RAW CAPTION: Got it, let's see. The video shows a person sitting at a table. First, they have a plate in front of them with some food. Then they move their hands—maybe adjusting something? Then they pick up a knife and fork. Wait, let's check the timestamps.

At the start, the person is sitting, hands on the table. Then they move their hands, maybe gesturing. Then they grab the utensils. The background is a plain wall with a light switch. The camera is static, maybe a bit shaky? Wait, the rules say to describe motion chronologically.

So step by step:

- Initial: Person seated at table, plate with food in front, hands on table.
- Then, hands move (maybe spreading them out?), then pick up knife and fork.

Appearance: Person in white shirt, plate with food, utensils on right side (since they pick up from there).

Spatial: Plate is center, utensils to the right of plate.

Camera: Static, no movement mentioned, but the video might have slight shake? Wait, the problem says "conclude with camera perspective and movement". The example output would need to say something like "static camera" or "slight shake".

Wait, the video is in sepia tone, but we don't mention color. Focus on motion.

Chronological order:

1. Person seated, hands resting on table beside plate.
2. Hands move (maybe placing on table, then picking up utensils).
3. Picks up knife and fork from right side of table, holding them up.

Wait, in the video, the first frame: hands on table, plate in front. Then in frame 2, hands move to the sides, then frame 3, hands move toward plate. Wait, no: frame 0: hands on table. Frame 1: hands moving. Frame 2: hands moving apart. Frame 3: hands on table. Frame 4: picks up utensils.

Wait, the video has a sequence:

0.0: person sitting, hands on table, plate in front.

0.3: hands spread out on table.

1.4: hands move towards the sides? Wait, maybe the movement is: they place hands on the table, then move them to the sides, then pick up the utensils.

Wait, looking at the frames:

[0.0] person at table, plate with food, hands on table.

[1.4] hands are moving apart (maybe pushing something), but the main action is the person's hands moving. Then [2.5] hands are further apart. Then [3.6] they pick up the utensils (since in frame 4, they are holding the knife and fork).

So the sequence:

- Initially, seated at a table with a plate of food in front.

- Hands move outward on the table.

- Then pick up knife and fork from the table's right side (where they were placed).

Appearance: Person in white shirt, plate has food, utensils are black (since it's sepia, but we describe as black in the video—wait, the rules say "color" but maybe the video is black and white or sepia. But the rules say to mention color if in the video. Wait, the problem says "Briefly describe their appearance and number (color, size, orientation)". So the person's shirt is white. The plate is white, food is small, utensils (knife and fork) are dark (since in the video, they are on the table to the right).

Spatial: Plate is centered on the table; utensils are to the right of the plate.

Camera: The camera is static, looking straight at the person, no noticeable movement.

So putting it all together in chronological order:

A person wearing a white shirt sits at a wooden table with a white plate of food in front. Their hands initially rest on the table, then move outward; subsequently, they pick up a black knife and fork from the table's right side, holding them up. The camera remains static, positioned directly in front of the subject.

Wait, check rules: exclude text recognition, named characters—so no "boy" or whatever. Just "person".

Let's structure:

- Chronological: initial position, then movement, then action.

So:

At the start, a person in a white shirt sits at a table with a white plate containing food directly in front. The person moves their hands on the table surface, then grasps a dark knife and fork placed to the right of the plate, lifting them toward the camera. The camera maintains a fixed position facing the subject.

Check for minimal background: wall with light switch is in the background, but only mention if essential.

The person's hands and chopsticks are moving: the person manipulates the chopsticks over the plate, lifting and repositioning them in deliberate motions.

The background (wall, light switch) is static with no shifting elements or fluid motion. No fire, water, smoke, or wind is visible.


A hand holding a white sheet of paper on a textured surface begins folding the paper diagonally, with both hands pressing down to create a crease; one hand wears a ring. The camera remains fixed in a top-down perspective throughout the sequence.

Hands and a white paper sheet are the discrete objects; the hands are actively folding and manipulating the paper through physical forces (e.g., pressing, creasing).

The dark textured surface in the background shows no uniform shifting or fluid motion. No fire, water, or wind effects are present.


RAW CAPTION: Got it, let's tackle this. First, I need to describe the video chronologically. The main subject is a man. Let's see the frames.

In the video, there's a man walking on a paved plaza. He's wearing a white short-sleeve shirt (though in the first frame, his sleeves are rolled up, but later maybe black? Wait, no, the description says he's in a white shirt. Wait, the first frame shows him with black under sleeves? Wait, no, the rules say to focus on motion and behavior. Let's check each frame.

The man is holding a cane. He's walking, moving his hand on the cane. The text on the screen is there, but we exclude text recognition. So the actions: he's walking, holding the cane, moving his hand. Then he turns around, so his motion is walking and turning.

Appearance: he's wearing a white shirt, dark pants, sunglasses. Size: medium, orientation: facing the camera initially, then turns.

Spatial relationships: background has buildings, trees, a bench, a black bag on the bench. But minimal background, so mention if essential. The man is on the plaza, with buildings to the left and right.

Camera: in the first frame, camera is close up. Then, as he turns, the camera might be steady or following him. Wait, the video starts with him in the frame, then he moves, and the camera follows his movement? Let's see the transition: in frame 0, he's facing, then frame 4 he turns his back, so the camera is moving to follow him.

Wait, the video shows him walking, then turning. So chronologically: the man walks forward, holds a cane, then turns to his right (so facing away from the camera). The camera is following his movement, maybe a slight pan to the right as he turns.

Wait, the first frame: he's facing the camera, walking. Then, in the next frames, he moves his hand on the cane, then turns. So the sequence is: the man walks on the plaza, holding a cane, gesturing with his hand while moving the cane, then turns his body away from the camera.

Appearance: he's a man with sunglasses, white shirt (maybe dark sleeves underneath? Wait, the first frame says "white shirt with rolled-up sleeves, revealing black under sleeves". Wait, in the video, the first frame: he's in a white shirt, but his sleeves are rolled up, so the black sleeves are visible. Wait, but the rules say to describe appearance. So "man wearing a white short-sleeve shirt with rolled-up sleeves revealing black undersleeves, dark pants, and sunglasses".

But the rules say "briefly describe their appearance and number". So main subject: one man.

Motion: he walks forward, then turns to the right, moving the cane in his right hand.

Camera movement: the camera starts with a medium shot, following him as he walks, then as he turns, the camera slightly pans to the right to keep him in frame.

Now, check the rules. Exclude text recognition. So ignore the yellow text.

Background: minimal, but there's buildings and a bench. But we can mention it's a plaza with buildings and a bench, but keep it minimal.

So putting it all together:

A man in a white shirt with rolled-up sleeves revealing black undersleeves, dark pants, and sunglasses walks forward on a paved plaza, holding a cane in his right hand and gesturing with his left hand as he moves. He then turns to his right, facing away from the camera while continuing to hold the cane. The camera follows his movement with a slight pan to the right.

Wait, check chronological order: he walks, then turns. The first part: he's walking, holding cane, gesturing. Then he turns. The background is a plaza with buildings and a bench, but minimal.

Wait, the first frame he's walking towards the camera, then moving forward. Then he turns. So the sequence is: the man walks, holds cane, gestures, then turns.

Also, check the appearance: shirt color, pants, etc.

Another thing: in frame 0, he's holding the cane, then frame 1, 2, 3 he's gesturing, then frame 4 he's turning. So the action is continuous.

So final caption should be concise, chronological paragraph.

Let's draft:

A man wearing a white shirt with rolled-up sleeves, dark pants, and sunglasses walks forward on a sunlit plaza, holding a cane in his right hand and gesturing with his left. He then turns his body to the right, facing away from the camera while maintaining his hold on the cane. The camera follows his movement with a slight pan to the right.

Check if it's concise and chronological. Yes.

The man (solid object) exhibits minor hand gestures and cane adjustments, moving due to his own locomotion and deliberate actions. These movements are localized and trackable with a bounding box.

The background (buildings, trees, bench) is static with no shifting, uniform motion, or environmental elements like fire, water, wind, or smoke. No fluid/environmental motion is dominant.


A man in a red shirt and blue jeans uses an orange chainsaw to cut a large orange pumpkin positioned on a green stand. He swings the chainsaw repeatedly, moving it around the pumpkin’s surface to slice through its outer layer. The pumpkin remains stationary on the stand, with a gray SUV and residential structures visible in the background. The camera maintains a fixed perspective, capturing the action from a consistent medium distance.

The man in red shirt and blue jeans is moving his arms and body to cut the pumpkin with a knife; the knife is moving due to manual force application.

The background elements (car, trees, house) remain stable with no shifting motion; no fluid/environmental motion (fire, water, smoke, wind) is observed.


RAW CAPTION: Got it, let's tackle this. First, the video shows a person in a black shirt massaging someone lying on a bed. Let's break it down chronologically.

In the first frame, the standing person is touching the leg of the person on the bed. Then, they adjust their position, moving their hands. The standing person is wearing a black short-sleeve shirt, the person on the bed is covered with a gray blanket, only their legs visible. The room has a window with blinds, a mirror, etc., but background is minimal.

Need to describe the motion: the standing person is massaging or moving the leg of the person lying down. Steps: first, the standing person's hands are on the leg. Then they shift, maybe talk (but caption doesn't need dialogue), then adjust hands. Spatial: standing person is next to the bed, the other person is lying down. Background: room with window, but keep it minimal.

Camera perspective: looks like a fixed shot, maybe a bit low angle, but no movement mentioned. The video frames show the same scene, so camera is static.

So the caption should be:

A woman in a black shirt stands beside a bed, massaging the leg of a person lying under a gray blanket. She adjusts her hands on the leg, shifting her posture while maintaining contact. The camera remains stationary, capturing the scene from a slightly low angle in a well-lit room with a window and mirror in the background.

Wait, check rules: focus on motion, chronological. So first, she's touching the leg (maybe starting with hands on leg), then moving (shifting posture), then continuing. Also, number of subjects: two people. Appearance: woman in black shirt, the other person with legs visible under gray blanket.

Make sure to mention chronological: initial action, then adjustment.

Let me rephrase:

In a well-lit room with a window and mirror, a woman in a black shirt stands beside a bed, placing her hands on the leg of a person lying under a gray blanket. She shifts her posture, adjusting her hands on the leg while maintaining contact. The camera remains stationary, capturing the scene from a low angle.

Check if background is essential: the rules say minimal unless essential. The window and mirror are part of the room, but maybe not essential for understanding motion. Wait, the rules say "mention spatial relationships if relevant". The woman is next to the bed, the other person on the bed. But maybe background can be brief.

Alternatively, maybe just say: A woman in a black shirt stands next to a bed, massaging the leg of a person lying under a gray blanket. She moves her hands along the leg, adjusting her stance. The camera is stationary, providing a low-angle view.

Wait, the problem says "conclude with camera perspective and movement". So "camera remains stationary" or "fixed shot".

Let me check the rules again:

a) Focus on motion and behavior of main subjects chronologically.

b) Briefly describe appearance and number.

c) Mention spatial relationships if relevant.

d) Conclude with camera perspective and movement.

e) Background minimal unless essential.

f) Exclude text, names, etc.

So main subjects: two people. Standing woman (black shirt), lying person (gray blanket over legs). Motion: she starts touching leg, then moves hands, shifts position.

Chronological: First, she places hands on the leg (0.0-0.5s), then shifts posture (0.5-2.5s), then continues.

So caption:

A woman in a black short-sleeve shirt stands beside a bed, placing her hands on the leg of a person lying under a gray blanket. She shifts her posture, moving her hands along the leg while maintaining contact. The camera remains stationary, capturing the scene from a low angle.

Wait, the "lying under a gray blanket" is part of the description. Also, the number: two people (one standing, one lying). Appearance: woman in black, person under gray blanket.

Check if spatial relationships: the woman is beside the bed, the person is on the bed. So "stands beside a bed, massaging the leg of a person lying on the bed".

Yes. Let's draft:

A woman in a black shirt stands beside a bed, massaging the leg of a person lying under a gray blanket. She shifts her position, adjusting her hands on the leg while maintaining contact. The camera remains stationary, providing a low-angle view.

Wait, the problem says "briefly describe their appearance and number". So two people: one standing (black shirt), one lying (gray blanket). The motion: she's moving hands, shifting.

Also, need to mention the action chronologically. So first, she's massaging (placing hands), then adjusting posture.

Yes. Let's write that.

Final caption:

A woman in

Two solid objects (people) are moving: one standing person gestures and shifts position, while another person lying down also shows subtle movements.

The background elements (walls, windows, furniture) show no significant shifting or fluid motion. No fire, water, smoke, or wind is visible.


Hands hold a dark red, glossy apple on a wooden surface; a knife slices horizontally through the apple, separating the top portion, which is then lifted away. The camera maintains a top-down view with minimal movement.

A hand and a knife interact with a red apple, cutting it. The apple is a discrete solid object undergoing physical deformation due to the knife's motion.

The background is a static wooden cutting board with no shifting elements or fluid/environmental motion (fire, water, smoke, wind).


RAW CAPTION: Okay, let's tackle this captioning task. First, I need to understand the video description provided. The user wants a concise, chronological paragraph focusing on the motion and behavior of main subjects.

Looking at the video description: it's a sequence where a person in pink with a drum and another in a kilt playing bagpipes. The main subjects are the two musicians. The pink-clad person is moving from left to right, drumming. The bagpiper is standing still, playing. Background has a stone wall and a picnic table, but the rules say to keep background minimal unless essential.

Chronologically, the video starts with the pink drummer on the left, then moves right. The bagpiper is stationary. The drummer's movement is from left to right across the frame. The bagpiper stays in place, so their position is consistent.

Need to mention their appearance: pink outfit with yellow feathers, large drum; bagpiper in dark blue kilt, red feather hat. Number: two people. Spatial relationship: the drummer is to the left of the bagpiper, moving past him.

Camera perspective: the description mentions the camera follows the drummer as he moves from left to right. So the camera is panning left to right, maybe slightly following the motion.

Check the rules: don't include text, named characters, or stylistic analysis. Keep background minimal. So stone wall and picnic table are in the background but only briefly mentioned.

Putting it all together: The drummer moves left to right, playing, the bagpiper stays still. Camera follows the drummer's movement. Mention their appearance briefly. Make sure it's chronological.

Possible structure: In the opening frame, the pink-clad drummer in a yellow feathered hat begins moving from left to right, drumming while wearing a bright pink outfit with yellow patterns. The bagpiper in a dark blue kilt and red feathered hat stands still, playing the bagpipes. As the drummer progresses, the camera pans right, capturing their movement against a stone wall backdrop with a picnic table. The drummer exits the frame to the right, while the bagpiper remains positioned to the right of the initial view.

Wait, the rules say "conclude with camera perspective and movement". So the last part should mention that. Let me check the example output format.

The user provided an example where the camera perspective is mentioned at the end. So the caption should end with "Camera follows the drummer’s left-to-right movement, panning slightly to the right."

Wait, in the given example, the caption ends with "The camera follows the drummer’s left-to-right movement, maintaining a steady perspective."

So in this case, the drummer moves left to right, so camera pans right. The bagpiper is stationary. The background elements are minimal, so maybe just mention the stone wall as part of the background but not too much.

Let me check the rules again: "background descriptions minimal unless essential for understanding motion." The motion here is the drummer moving, so maybe the stone wall is essential for context (e.g., they're in front of a stone building). But the user's example didn't include much background, so perhaps just mention "against a stone wall backdrop" briefly.

Wait, the example output from the user's problem statement isn't provided here, but the instructions say to follow the format. Let me structure it step by step.

First, chronological order:

- The video starts with the drummer moving from left to right (frame 0 to 4). The bagpiper is stationary. The drummer's position changes relative to the bagpiper.

Description of motion: The person in pink (drummer) moves from left to right across the frame, drumming. The bagpiper remains stationary, playing.

Appearance: Drummer in bright pink outfit with yellow feathered hat, large drum. Bagpiper in dark blue kilt, red feathered hat, playing bagpipes.

Spatial relationship: The drummer is initially to the left of the bagpiper, moving past him to the right.

Camera movement: The camera follows the drummer's movement, panning right.

Background: stone wall and picnic table, but minimal. Since the motion is the main focus, maybe just mention "against a stone wall backdrop."

Putting it all into a concise paragraph:

The drummer in a bright pink costume with yellow feathered headpiece marches from left to right, drumming vigorously while carrying a large pink drum. To their right, a bagpiper in a dark blue kilt and red feathered hat stands stationary, playing the bagpipes. As the drummer moves across the frame, the camera pans right, capturing their motion against a stone wall backdrop with a picnic table visible in the background.

Wait, but the rules say "conclude with the camera perspective and movement". So the last part should be about the camera. Let me check the example output. The

The individual in the pink costume is actively dancing with rhythmic leg and arm movements while holding a drum; the person in the kilt exhibits controlled hand and head motions while playing bagpipes.

The stone wall and benches in the background show no shifting or displacement, indicating a stable environment. No fire, water, smoke, or wind motion is observable.


The video begins with a black screen, transitioning to a scene where a camera on a tripod is positioned on a path in front of a grassy hill. A person wearing dark green pants and a brown jacket walks into the frame from the left, approaches the tripod, and jumps over it, landing on the grass. The camera remains stationary throughout, capturing the motion from a fixed ground-level perspective.

A person (photographer) enters the frame, walks toward the tripod, and performs a jump over the hedge, exhibiting discrete locomotion.

The grassy hedge and brick building in the background remain static with no uniform shifting; no fire, water, smoke, or wind motion is present.


Two girls sit side by side; the left girl with long dark hair and a blue floral top uses a lighter to light her candle, then holds it up and moves it toward her face. The right girl, with light brown hair and a light blue shirt, holds a candle. The camera remains static, capturing their upper bodies against a plain wall.

Two people are moving: the left person brings a food item to her mouth and chews, while the right person drinks from a container. Both are discrete solid objects moving due to their own locomotion (eating, drinking, and hand gestures).

The background (wall and grid) is static with no fluid motion or environmental effects; no dominant fire, water, smoke, or wind motion observed.


A person with curly hair, wearing a blue shirt and earrings, is positioned in front of a wooden door and louvered window. They open their mouth, smile to reveal teeth, then close their mouth while speaking. The camera maintains a close-up, static perspective focused on the upper body and face, with minimal background detail visible.

The person's face and mouth are moving due to speaking.

Background is static (wooden door and wall). No fluid or environmental motion detected.


RAW CAPTION: Got it, let's break down the video. The first frame shows a white liquid being poured into a metal bowl. Then, the next part shows a carton (maybe milk or cream) pouring into a baking pan with white cups. Then, a hand places a chocolate bar into a white container with a blue cloth. Next, there's a pot with a dark liquid being poured into a white bowl. Finally, chocolate is poured into a baking pan with a blue cloth on top.

Wait, need to go chronologically. Let's list each scene in order:

1. [0.0] White liquid poured into metal bowl.
2. [1.1] Carton (light blue and white, maybe milk) poured into baking pan with white cups.
3. [2.5] Hand placing a chocolate bar into a white container with blue cloth. Wait, the third frame shows a hand placing chocolate? Wait the video's frames: first frame is pouring liquid into metal bowl, then second frame shows pouring from carton into pan with cups, third frame shows a white cup (maybe a dessert) with a blue cloth? Wait no, the user provided the frames:

Frame 0: liquid into metal bowl.

Frame 1: carton pouring into pan with white cups (so maybe a baking dish with cups, like for individual portions).

Frame 2: white cups (like individual dessert molds) placed in a pan, then a blue cloth is on top? Wait the second frame: "a carton pouring into a baking pan with white cups" then next frame shows "a white cup (maybe a dessert) with a blue cloth" — wait no, the video description:

Wait the user's input:

<0.3 seconds> [pouring white liquid into metal bowl]

<1.4 seconds> [pouring liquid from carton into a baking pan with white cups]

<2.5 seconds> [white cups in pan with blue cloth, then a chocolate bar is placed on top? Wait no, the third frame description says "Galaxy chocolate bar on white cup with blue cloth"]

<3.6 seconds> [pouring dark liquid (maybe chocolate) into a white bowl]

<4.7 seconds> [chocolate poured into a baking pan with a blue cloth on top]

Wait the frames:

1. White liquid poured into metal bowl.

2. Carton pouring into pan with white cups.

3. Chocolate bar placed on white cup with blue cloth.

4. Dark liquid poured into white bowl (maybe chocolate).

5. Chocolate poured into baking pan with blue cloth.

So the chronological sequence of actions:

- First, a white liquid (like milk or cream) is poured from a container into a metal bowl.

- Then, a carton (likely milk or cream) is poured into a baking pan that contains white cups (possibly dessert molds).

- Next, a chocolate bar is placed on top of a white cup (which is in the pan) with a blue cloth visible.

- After that, a dark liquid (probably chocolate) is poured from a container into a white bowl.

- Finally, chocolate is poured into a baking pan that has a blue cloth on it.

Now, the main subjects are the liquids being poured, the containers, and the chocolate bar. The appearance: white liquid (color, flow), carton (blue and white?), white cups (light-colored, maybe ceramic), chocolate bar (brown, rectangular), dark liquid (brown, viscous), blue cloth (color).

Spatial relationships: pouring into metal bowl (close-up, top-down), carton pouring into pan (top-down), chocolate bar placed on cup (pan with cups), dark liquid into bowl, chocolate into pan with cloth.

Camera perspective: likely top-down shots for most frames, showing the pouring action.

Background: minimal, maybe kitchen countertop.

So the caption should be chronological, concise, mention motions, appearance, spatial if relevant, conclude with camera.

Let's draft:

A white liquid is poured from a container into a metal bowl. Then, a carton pours a similar liquid into a baking pan containing white cups. A hand places a chocolate bar onto a white cup within the pan, which has a blue cloth beneath it. Subsequently, a dark liquid is poured from a container into a white bowl. Finally, chocolate is poured into a baking pan topped with a blue cloth. The camera maintains a top-down perspective throughout the sequence.

Check if it's concise. Remove unnecessary words. Let's see:

"A white liquid is poured from a container into a metal bowl. Next, a carton pours liquid into a baking pan with white cups. A chocolate bar is placed onto a white cup in the pan, which has a blue cloth underneath. Then, dark liquid is poured into a white bowl. Finally, chocolate is poured into a baking pan with a blue cloth. The camera is top-down throughout."

Yes,

Discrete objects include a blue spatula spreading mixture in a pan, hands pouring ingredients (milk, butter, chocolate sauce), and chocolate pieces being placed into the pan. These objects move due to explicit physical interactions (pouring, spreading, placement).

The background (countertop) remains static throughout; no fluid or environmental motion (fire, water, wind) dominates the video. The liquid flows (milk, chocolate) are part of controlled culinary actions, not ambient phenomena.


A person in a dark long-sleeve shirt holds a metallic clarinet, their right hand adjusting finger positions over the keys while seated in front of an open sheet music book on a wooden table. The sheet music displays musical notation, and the person’s left hand rests near the instrument’s base. The camera maintains a static top-down perspective throughout, focusing on the hands, clarinet, and sheet music without movement.

The person's hands are moving to press the keys of the clarinet, demonstrating controlled motion from explicit physical forces (muscle movement) during playing.

No shifting backgrounds or fluid/environmental motion (fire, water, wind). Background (table and sheet music) is static and unchanging.


A woman with a ponytail, wearing black athletic clothing, performs an exercise on a gym machine, pulling a handle toward her torso while standing in front of the equipment; she then returns the handle to its starting position. The scene occurs in a well-lit gym with other exercise machines visible in the background, and the camera remains stationary throughout the sequence.

A person (woman) performs discrete physical movement (arm extension/retraction on gym equipment) with explicit force application to weights.

Static background elements (window, gym structure) show no uniform shifting; no fire, water, smoke, or wind motion detected.


A diapered baby stands on a light-colored floor in front of a couch, gripping the cushion with both hands. The baby shifts weight, lifts its head upward, and adjusts its stance while maintaining contact with the couch. The camera remains close and slightly shaky, capturing the baby’s movements against a plain background.

A baby (discrete solid object) exhibits localized movements: shifting weight, turning head, and raising arms while interacting with an object on the ledge.

No shifting backgrounds or fluid/environmental motion (fire, water, wind) detected. Background elements (window ledge, floor) remain static throughout the clip.


A woman with brown hair, wearing a black shirt with red splatters, lies reclined in a chair while a tattoo artist wearing black gloves applies ink to her upper body using a machine. The artist, positioned to her right, moves the tattoo machine steadily over her skin as the woman remains still. Background shelves with colorful bottles are visible. The camera maintains a close-up, slightly shaky perspective focused on the tattooing process.

Tattoo artist's hands (wearing gloves) are moving in a repetitive motion to perform the tattoo; client is mostly stationary.

Background (shelf with bottles) is static. No ambient environmental motion (fire, water, smoke, wind) present.


A small child wearing a purple hooded jacket, dark jeans, and purple sneakers stands on a concrete surface, initially facing downward. The child shifts weight, lifts one leg, and begins moving arms rhythmically in a dance-like motion. The camera remains stationary with minimal shake throughout.

The child is moving by walking, which is a form of locomotion.

The background (concrete ground and grass) is static. No fluid or environmental motion (fire, water, wind) is present.


A person uses a blue-handled paintbrush to apply a vibrant red paint to light-colored wooden slats of a crate, moving the brush in smooth strokes across the surface. The brush glides over the wood, evenly distributing the paint as the red color covers the slats. The camera maintains a close-up perspective, focusing on the brush motion and the crate, with minimal background detail visible. The scene captures the sequential application of paint from one slat to another, highlighting the fluid movement of the brush and the transformation of the wooden surface.

A hand and brush (discrete solid objects) move across a wooden structure; brush motion is driven by hand movement and physical contact with the surface.

Background (pink wall) is static and shows no shifting or environmental motion; no fire, water, smoke, or wind present.


A boy in a black shirt sits at a piano, playing with his hands on the keys. He turns his head to face the camera. An organ with circular holes stands behind him. The camera remains stationary throughout the scene.

A person (solid object) is moving their hands on the keyboard keys and turning their head toward the camera.

The background (wall, decorative panel, and framed picture) shows no shifting or fluid motion; no fire, water, smoke, or wind is observed.


RAW CAPTION: Okay, I need to generate a concise caption for this video based on the user's instructions. Let me start by looking at the video description provided. The video shows a crowded dance floor with people moving around. The setting is a dimly lit venue with colorful lights, maybe a club or a ballroom. The main subjects are the people dancing, so I should focus on their motion and behavior.

First, the rules say to describe the motion and behavior in chronological order. So, I need to note how the people are moving. The video starts with a crowd dancing, maybe in a circle? The frames show people in different positions, but it's a bit blurry. The user mentioned that the main subjects are people, so I should mention the number and their actions. Since it's a crowded place, I can say "a large crowd" or "numerous people."

Looking at the appearance: they're silhouettes because of the lighting. The description says it's night, so the scene is dark with purple and red lights. The people are dressed in dark clothing, but since it's dark, maybe not much detail. The spatial relationships: the crowd is on the dance floor, maybe moving in circles or shifting positions. The background has some structures, like lanterns and decorations, but the user says to keep background minimal unless essential. So maybe just mention the lighting is from overhead lamps and the stage area.

Chronological order: the video starts with the crowd dancing, then maybe the movement changes slightly. The first few frames show people in motion, perhaps rotating or moving in a circle. The caption needs to be concise, so maybe describe the initial action and how it progresses.

Camera perspective: the user says to mention the camera movement. The original video might have a slight shake or pan, but the description doesn't specify. The user's example in the output format includes "slight shake" as an example. Wait, in the given video, the frames are described as a series of clips where people move. The user's example output mentions "slight shake," but I need to check if the video has any camera movement. The problem states that the camera might be static or moving. Since the user's rules say to include camera perspective and movement, I need to infer. The video shows a crowd in motion, and if it's a handheld camera, maybe there's a slight shake. Alternatively, maybe the camera is stationary but the crowd moves around it.

Wait, the user's example in the instructions says: "Conclude with the camera perspective and movement (e.g., top-down, pan left, slight shake)." So for this video, since it's a dance floor with people moving, the camera is likely stationary or moving slightly. The problem statement says "the video" and the frames are sequential, but the user hasn't specified camera movement. However, in the given example outputs, they mention "slight shake." Maybe the video has a slight shake. Alternatively, if the camera is fixed, it's static.

Wait, the user's rules say "exclude text recognition, named characters, or stylistic analysis." So focus on motion, appearance, spatial, camera.

Looking at the video description: [0.0 second] to [5.0 second], the scene is a crowd dancing under colorful lights. The people are moving around, maybe in a circle. The initial frames (0.0 to 5.0) show people in motion. The caption should describe the chronological order: the crowd is dancing, moving in different directions.

Wait, the user says "chronological paragraph," so first, the crowd is present, then their movements. Let me check the example output they provided. The output format is a paragraph. Let me think of an example.

Example: "A large crowd of people, mostly in dark clothing, dance energetically on a dimly lit floor illuminated by purple and red lights. The dancers move in circular patterns, shifting positions as they interact. The camera remains stationary with a slight shake, capturing the dynamic motion from a low angle."

But the user's example might be different. Let me stick to the rules.

Main subjects: people, numerous. Appearance: silhouettes (since it's dark), maybe their clothing is dark. Motion: dancing, moving in circles, shifting positions. Spatial: around the central stage or dance floor. Background: minimal, just lights. Camera: probably static or slight shake.

So, putting it all together.

Start with the main action: "A large crowd of people, mostly in dark clothing, dances energetically on a dimly lit dance floor illuminated by purple and red overhead lights." Then describe their movement: "As the video progresses, the dancers move in shifting circular patterns, occasionally changing positions as they interact with one another." Then camera: "The camera remains stationary with a slight shake, capturing the scene from a low angle."

Wait,

Discrete solid objects (people) are dancing and moving around the dance floor.

No shifting background elements; no visible fluid or environmental motion (fire, water, wind).


A shirtless man wearing black pants and barefoot stands in a dojo with wooden walls and martial arts equipment. He swings a long white rope in a circular motion, moving it through his hands. The screen then cuts to black. The camera remains stationary throughout.

A shirtless man is actively moving a long white rope in a rhythmic fashion, causing the rope to oscillate and extend.

The background (wooden walls, posters, gym equipment) is stationary. No environmental fluids (fire, water, smoke) or wind motion is observed.


The video opens with a close-up of a car tire. Two hands with light skin enter the frame, sequentially pointing at various sections of the tire's tread pattern. The hands move in and out of the frame, directing attention to specific tread areas. The camera maintains a close-up view, focusing on the tire and the hands' gestures, with the ground visible in the background.

A person's hands are moving to point at and touch the tire tread. The tire is stationary.

Background is static (ground and car body). No fluid or environmental motion (fire, water, smoke, wind) observed.


A person in a checkered shirt on the left holds and manipulates a plastic bag, turning it and waving it, while a shirtless person on the right shifts position, moving their head and body. Both subjects are in static split-screen frames with minimal background detail.

Two discrete individuals: left individual manipulates a cloth-like object with arm movements; right individual shows slight head/shoulder motions while lying down.

Background elements (room furniture, bed) show no uniform shifting; no fluid/environmental motion (fire, water, smoke, wind) present in either scene.


The video shows three children playing on a sandy field. Initially, a blue-shirted child and an orange-shirted child stand on the left, while a white-shirted child is near a swing set on the right. The blue-shirted child runs rightward across the field, followed by the orange-shirted child. The white-shirted child remains near the swing set. The camera pans right to follow the running children, with the background featuring grassy patches and a concrete wall.

Children are running and moving across the dirt field. These are solid objects in motion due to their own locomotion.

The background (trees, water, distant hills) is stable and shows no significant shifting or fluid motion (e.g., no fire, water flow, smoke, or strong wind). The ground is static.


A person’s arm, wearing a striped shirt, extends into the frame holding a trowel, applying and smoothing white plaster across a wall section in repeated horizontal motions. The plaster covers a rectangular area adjacent to a vertical gap on the right. The camera remains stationary, capturing the action from a fixed close-up angle.

A hand holding a trowel is moving to spread a white substance (plaster) on a wall surface. The motion is deliberate and controlled.

No shifting background or fluid/environmental motion (e.g., fire, water, wind). The background (wall and adjacent structure) is static.


A person with long blonde hair, wearing yellow sunglasses and a blue shirt, sits outdoors near a black railing. They hold a checkered-pattern hookah hose, bringing it to their mouth and inhaling. The hookah, featuring a glass top and metallic base, rests on a table in front of them. The camera gradually zooms in to focus on the person’s action as they exhale, with greenery visible in the background.

A person (discrete solid object) is moving their head and hand while using a hookah. The hookah itself is stationary on a table, and the person’s motions are due to explicit physical actions (inhaling/exhaling).

The background features a static black fence and trees with no significant shifting or fluid motion (e.g., no fire, water, or smoke). Background elements remain consistent across frames, indicating no ambient environmental motion.


A person wearing a red shirt lifts a section of dark hair with one hand, then uses a red hair straightener to glide downward along the hair strand in front of a closet with hanging clothes. The camera remains steady, capturing the motion from a close-up perspective.

The person is moving their hands and head while styling hair, using a red tool and a black object (likely hair styling tools). This is discrete, solid object motion driven by the person's own physical actions.

Static closet background with hanging clothes; no fluid or environmental motion (fire, water, wind) present. Background elements are stationary relative to the frame.


RAW CAPTION: Got it, let's tackle this video captioning task. First, I need to watch the video and note the main actions. The video shows a swimming pool area with people. Let's break it down chronologically.

In the first frame, there are several people around the pool. Then, in the next frames, a person jumps into the pool—probably from the diving board. Then another person might be walking towards the board. Let's check the sequence.

Frame 0: People are standing, maybe some on the deck, others near the pool. There's a person at the edge of the pool, preparing? Then frame 1: someone jumps into the pool, creating a splash. Then in frame 2, maybe the person who jumped is now in the water, and another person is moving towards the diving board. Frame 3: the person on the diving board walks towards the edge, maybe to jump? Wait, no, in frame 0, there's a person on the board. Then in frame 1, they jump into the pool. Then in frame 2, another person (maybe two people) are moving on the board. Wait, the video has a sequence where one person jumps, then another person is on the board, then another steps up.

Let's list the main motions:

- Start: A person stands at the edge of the pool (diving board area), others around.
- Then the person jumps into the pool, making a splash.
- After the splash, another person (maybe two) approach the diving board, one steps up and walks towards the edge.

Wait, the frames:

0.0s: Person at diving board, maybe waiting. Others around.
0.3s: Person jumps from diving board into pool, splash.
1.4s: After splash, maybe the person is in water, then another person (two people) are on the deck near the pool? Wait, the description says in frame 2, two people are walking towards the pool. Wait, the frames: first frame, person at edge. Second frame, they jump. Third frame, another person is walking on the deck, then fourth frame, two people approaching.

Wait, the user's example shows that in the video, a person jumps into the pool, then another person is on the board, then another steps up.

So chronological order:

1. A person stands at the pool's diving board edge (near the water).
2. The person jumps into the pool, creating a splash.
3. After the jump, another person approaches the diving board, steps up, and walks along the deck towards the pool edge.
4. Then, a second person (or two) are now near the diving board, moving towards the edge.

Appearance: The jumpers are individuals, likely in swimwear (dark swim trunks, maybe). The people around are spectators, some with cameras (tripods).

Spatial: The diver jumps from the diving board into the pool. The person who steps up is on the deck, moving towards the board.

Camera perspective: The video is shot from a high angle, top-down view, looking over the pool and deck. The camera doesn't move much; it's static or slight pan.

Background: Minimal, mostly the pool deck, spectators, tripods. But according to rules, keep background minimal.

So putting it all together:

A person in dark swimwear stands at the pool's diving board edge, then jumps into the water, creating a splash. Subsequently, two people in swimwear walk toward the diving board, with one stepping onto the board and moving toward the water. The camera remains in a static top-down position, capturing the pool area and surrounding deck.

Wait, let's check the frames:

Frame 0: Person at edge of pool (diving board), others around (spectators, some with tripods).

Frame 1: The person jumps into the pool (splash).

Frame 2: After splash, a person walks along the deck (toward the pool), and another person is near the board.

Frame 3: The person on the deck walks further, and another person steps onto the board.

Frame 4: Two people on the deck, one near the board.

Wait, the video description in the user's message shows:

Frame 0: person at edge.

Frame 1: jump.

Frame 2: after jump, a person walks on the deck, another person approaches.

Frame 3: two people walking towards the pool.

Frame 4: two people near the diving board.

So the main actions:

- One person jumps from the diving board into the pool (splash).

- Then, another person (or two) move from the deck toward the diving board; one steps onto the board and walks toward the edge.

Appearance: The jumpers are in swimwear (dark color, size: individual). The others on deck

Multiple discrete solid objects (people) are moving: divers entering the water (causing splashes), swimmers in the pool, and deck personnel walking or standing. Their motion is due to locomotion (walking, diving) and physical forces, trackable with bounding boxes.

The pool deck, walls, and fixed structures show no uniform shifting, indicating stable background. Water in the pool exhibits minor splashes and ripples from human activity (diving/swimming), but these are secondary effects caused by discrete objects rather than dominant fluid motion. No fire, smoke, or significant wind effects observed.


A boy in a pink shirt and dark shorts and a girl in a white dress with red floral patterns and yellow pants stand on a colorful mat. The boy extends his arm toward the girl, who then turns and walks forward, looking down. The camera zooms in on the girl's face as she moves.

Two children (discrete solid objects) interact: one stands and moves away, the other sits then stands. Their locomotion is caused by explicit physical forces (walking, standing up) and minor hand contact. Other background people move minimally but are not the focus.

Static background elements (purple padded walls, colorful floor) show no shifting or fluid motion. No fire, water, smoke, or wind effects observed.


RAW CAPTION: Okay, let's tackle this video captioning task. First, I need to understand the requirements. The user wants a concise, chronological paragraph describing the video, focusing on the main subjects' motions and behaviors in order. They specified rules like mentioning appearance, spatial relationships, camera perspective, etc., but minimal background.

Looking at the video frames provided:

The first frame shows a city rooftop with three people. One is on a ladder, another in a purple hoodie hanging upside down, and a third person in the foreground. The second frame is a close-up of a woman in a black leather jacket holding a microphone. Third frame is another angle of her speaking. Fourth frame shows a person in purple bending over, and a hand holding a microphone towards them.

So the sequence is: Start with the rooftop scene with multiple people, then cut to the woman speaking, then the person in purple. Need to describe each action in order.

Main subjects: The woman (black leather jacket, speaking into mic), the person in purple (hanging, then bending over). The third person on the ladder might be secondary.

Chronological order: The video starts with the rooftop scene where someone is hanging upside down. Then the camera focuses on the woman with the mic. Next, the person in purple is seen bending over while being interviewed.

Need to mention their appearances: woman in black leather jacket, purple hoodie. Spatial relationships: the woman is in front of the city buildings, the purple person is on the ground. Camera movement: starts with a wide shot, then close-ups.

Check if background is essential. The city buildings are in the background, but maybe minimal mention. The user says "keep background descriptions minimal unless essential for understanding motion." Since the motion is on the rooftop, maybe just "cityscape" as background.

Avoid text recognition (like the logo on the mic), named characters, stylistic analysis.

Structure the caption:

1. Start with the rooftop scene: a person in purple hoodie hanging upside down from the roof edge, another person on a ladder.
2. Camera shifts to close-up of the woman in black leather jacket holding a microphone.
3. Then the person in purple bends over as someone holds a microphone towards them.

Check the order. The video starts with frame 0: a rooftop scene with three people (one hanging, one on ladder, one in foreground). Then frame 1: woman with mic. Frame 2: same woman. Frame 3: purple person bending over with mic.

Wait, the timestamps are [0.0] to [4.7]. So the first frame shows the rooftop with the hanging person. Then the next frames are close-ups of the woman and the purple person. So the sequence is: the scene starts with the person hanging, then the woman speaking, then the purple person bending over.

So the caption should start with the hanging person, then the woman, then the purple person. But the user says "chronological order of the video."

Wait, the first frame is [0.0] which is the rooftop scene with the hanging person, then [1.0] is the woman speaking, [2.0] same, [3.0] person bending over.

So the video starts with the rooftop scene where a person in purple hoodie hangs upside down from the roof edge. Then the camera shifts to a woman in a black leather jacket speaking into a microphone. Next, the camera focuses on the person in purple bending over while a hand holds a microphone towards them.

Check appearance: "person in purple hoodie" (size, color), "woman in black leather jacket".

Spatial relationships: The hanging person is on the roof edge, the woman is in front of the cityscape. The purple person bends over on the ground.

Camera perspective: The initial shot is a medium wide shot of the rooftop, then close-ups of the woman and the purple person. Camera movement: pans or cuts to close-ups.

Wait, the first frame is a wide shot, then cuts to close-up of the woman, then to the purple person. So camera movements are cuts to close-ups.

Need to describe camera perspective and movement. The instructions say "Conclude with the camera perspective and movement (e.g., top-down, pan left, slight shake)."

So the initial shot is a medium-wide, then close-ups. So maybe "starting with a medium-wide shot of a rooftop scene, then cutting to close-ups of the woman and the purple-clad individual."

Now, the final caption should be concise. Let's piece it together:

On a rooftop with a cityscape background, a person in a purple hoodie hangs upside down from the roof edge while another individual stands nearby. The camera then cuts to a close-up of a woman in a black leather jacket speaking into a microphone. Subsequently, the camera shifts to a close-up of the person in the purple hoodie bending over as

A woman holding a microphone (talking) and a person in purple clothing (bending over) are discrete solid objects moving due to locomotion or physical interaction.

Static background elements (buildings, ground) show no uniform shifting. No fire, water, smoke, or wind effects observed.


A person in a light-colored shirt and dark pants takes a pool shot from behind a wooden pool table under a hanging lamp, striking the cue ball which rolls across the green felt surface; after the shot, the person turns and walks away from the table while the camera remains stationary, capturing the scene from a fixed angle with minimal background details.

A person is walking around the pool table, moving from the right side of the frame to the left side. The pool balls remain stationary.

The background elements (walls, chair, lamp) are static and do not shift. There is no fluid or environmental motion (fire, water, smoke, wind) present.


RAW CAPTION: Okay, I need to generate a concise caption for this video based on the rules provided. Let me read through the instructions again to make sure I don't miss anything.

First, the task is to create a chronological paragraph describing the video. The main points are focusing on motion and behavior of subjects, their appearance and number, spatial relationships, camera perspective, minimal background, and exclude text or named characters.

Looking at the video frames:

- The video starts with three people in a kitchen. They're wearing different colored jackets and beanies: one blue jacket with yellow beanie, one pink hoodie with blue beanie, and one gray suit with pink beanie. All have sunglasses.

- In the first frame (0.0s), they're standing in the kitchen. The person on the left is near the fridge, middle is by the counter, right is near the sink.

- At 0.3s, the right person moves out of frame, maybe dancing or moving away. Then the middle person adjusts their hat. Wait, the description says at 1.4s the right person is gone, but the next frame (1.4s) shows two people. Wait, the user provided the video frames as [0.0], [0.3], [1.4], etc. Let me check the exact frames given.

The provided frames:

0.0s: three people in kitchen. Left: blue jacket, yellow beanie. Middle: pink hoodie, blue beanie. Right: gray suit, pink beanie. All with sunglasses.

0.3s: Right person is now out of frame. The left and middle are still there. Middle person moves towards left.

1.4s: Two people. Left is blue jacket, yellow beanie (moved closer to camera). Middle is pink hoodie, blue beanie. Both adjust sunglasses.

2.5s: They are close together, moving towards camera. Left person's hair is visible, middle person is now in front. They are smiling, maybe dancing.

3.6s: Closer view, all three are now in frame again? Wait, no. The description says in frame 3.6s, three people are close, smiling. Then in 4.7s, the middle person is in front, left is to the side, right is out of frame again?

Wait, maybe the person on the right moves in and out. Let's parse each frame as per user input.

User's frame descriptions:

[0.0] Three people in kitchen. Left: blue jacket, yellow beanie, sunglasses. Middle: pink hoodie, blue beanie, sunglasses. Right: gray suit, pink beanie, sunglasses. All standing.

[0.3] Right person moves out of frame (maybe exits to the right). Left and middle are there. Middle person moves towards left, adjusts beanie?

[1.4] Two people visible. Left person (blue jacket) adjusts sunglasses. Middle person (pink hoodie) is now in front of left person. They're closer.

[2.5] Both move towards camera, smiling. Left person raises hands, middle person is next to them.

[3.6] Closer, three people are visible again. Left and middle are close to each other, right person (gray suit) is partially visible on the right.

[4.7] Two people. Left person (blue jacket) is to the left, middle person (pink hoodie) is in front. They're smiling, moving towards camera.

Wait, but the user's input shows the video as follows:

The frames are:

0.0: three people in kitchen.

0.3: right person moves out (so now two people left).

1.4: two people (left and middle) now closer.

2.5: they move towards camera, smiling.

3.6: three people again? Or maybe two.

Wait, the user's frame descriptions are:

At 0.0 seconds: three people.

At 0.3 seconds: right person is gone (maybe moves out of frame).

At 1.4 seconds: two people visible.

At 2.5 seconds: two people moving towards camera.

At 3.6 seconds: three people close together.

At 4.7 seconds: two people (left and middle) moving towards camera.

Wait, but the user provided the initial description as:

<0.3 seconds> [frame 1]

<1.4 seconds> [frame 2]

etc.

So the video shows three people initially. The first frame (0.0s) has all three. Then, at 0.3s, the right person moves out of frame (exiting to the right). Then at 1.4s, two people are left (left and middle). They adjust their sunglasses. At 2.5s,

Three individuals (wearing distinct clothing and headwear) exhibit discrete motion: adjusting headgear, shifting positions, and interacting with each other in a confined space.

The kitchen background (cabinets, fridge, appliances) remains static with no fluid or environmental motion (fire, water, smoke, wind) observed.


A man in a blue shirt and black shorts performs repeated step-like movements while a man in a maroon shirt and black pants stands to his right, gesturing. The blue-shirted man moves from left to right across the frame, executing lunges, while the maroon-shirted man remains stationary, using hand motions. The camera remains fixed, capturing the scene from a mid-level perspective in a gym setting with minimal background details.

Two solid human subjects: person in blue shirt performing discrete lunging movements (discrete locomotion), person in maroon shirt standing still as instructor (no motion).

The gym background (weight racks, walls, floor) is stationary with no visible fluid motion, smoke, or wind; no environmental elements exhibit dominant ambient behavior.


RAW CAPTION: Got it, let's break this down. The video shows a person on a snowy field. First, the person is on a sled, bending over. Then they stand up, move the sled, and start pulling it with a rope. Wait, the sequence: in the first frame, they're crouched on the sled, hands on it. Then they rise, step onto the sled? Wait, no, looking at the frames: frame 0 to 5. Let's see the actions chronologically.

Frame 0: Person is bent over, on the sled (which has a wooden seat, metal runners), pulling with a rope. They're on snow. Frame 1: They start to stand up, maybe? Frame 2: More upright, moving the sled? Frame 3: They're standing, pulling the sled forward. Wait, the description says the person is pulling the sled. Wait, the sled has a rope attached. So the person is using the rope to pull the sled.

Wait, let's check each frame:

0: Person (brown jacket, dark pants, red hat) is on the sled, hands on the sled, leaning forward, preparing to pull. Sled is wooden with metal runners, rope attached to a wooden pole.

1: Person is standing, moving the sled forward? Wait, the position: first frame, they're on their knees or bent over the sled. Then in frame 2, they're standing, but the sled is moving? Wait, the video shows motion. So the person starts by being on the sled, then stands up and pulls the sled with the rope.

Wait, the key is the chronological order. Let's list the steps:

1. The person is initially bent over on the sled, hands gripping it. They are wearing a brown jacket, dark pants, red hat. The sled is wooden with metal runners and a rope attached to a wooden pole. The background is snowy.

2. They stand up, shifting their position, moving the sled forward.

3. They pull the sled with the rope, moving across the snow. The sled leaves tracks.

4. As they move, the camera captures their motion from a distance, possibly following them or static? Wait, the camera perspective: the video starts with a shot of the person on the sled, and as they move, the camera might be following or static. The description says "conclude with camera perspective and movement".

Background: snowy field, minimal. No other objects or people.

Now, need to write in chronological order. Let's see:

First, the person is on a wooden sled with metal runners, attached to a rope, in a snowy area. They are wearing a brown jacket, dark pants, red hat. Initially, they are bent over the sled, hands on it. Then, they rise to a standing position, gripping the sled's edge, and begin pulling it forward using the rope. As they move, they continue pulling the sled across the snow, leaving a trail behind. The camera maintains a static, top-down view throughout, capturing the person's motion across the snowy landscape.

Wait, check the rules: focus on motion and behavior chronologically. So steps: initial position (bent over), then standing up, pulling sled.

Also, mention spatial relationships: e.g., the rope is attached to the sled, person is in front of the sled? No, the person is on the sled. Wait, the sled is behind them? Wait, the rope is attached to the sled, so when they pull, they're pulling the sled. So the sled is in front of the person.

Wait, the sled is the thing they're pulling. So the person is behind the sled, pulling it. Wait, the video: the sled has a wooden seat, and the person is on the sled. Wait, no. Wait, the first frame: the person is crouched on the sled, which is on the snow. So the sled is a sled, like a sledge, and the person is sitting on it? But in the first frame, they're bent over. Maybe they're moving the sled, but the person is on the sled. Wait, maybe the sled is a sort of platform, and they're pulling it. Wait, the video shows the person using the rope to pull the sled. So the sled is in front of them, and they're pulling it.

Wait, let's re-express:

The person (wearing brown jacket, dark pants, red hat) is initially bent over a wooden sled with metal runners, which is attached to a rope. They stand up, then grip the rope and pull the sled forward across the snow, moving in a straight line while leaving tracks behind. The camera remains static, capturing the person's movement from a slightly elevated angle.

But let's check the exact frames:

Frame 0: Person is on the sled

A person in winter clothing is actively pulling a sled across snow, moving forward by exerting force on the sled via a rope; the sled is a solid object being displaced by the person’s locomotion.

The snowy background shows no significant fluid motion (e.g., wind-driven snow, flowing water) or uniform shifting; static elements like snow and distant terrain remain consistent across frames.


Hands with yellow nail polish manipulate a green and white "Glue Dots" container to apply adhesive dots to the ends of a light brown rolled object on a wooden desk. The hands press the container against the roll’s edges, securing the tape with the dots. The camera maintains a close-up perspective centered on the hands and the rolled object, with the desk surface and scattered items faintly visible in the background.

Hands are manipulating a container of Glue Dots and applying the dots. The glue dots (small adhesive objects) are being moved by the hands.

The background (cluttered desk, basket, bottles) is static with no shifting. No fluid or environmental motion (fire, water, wind) is present.


A hand sprinkles white crumbly ricotta cheese onto a red sauce base in a black skillet. The hand then adds finer white parmesan cheese over the ricotta. Next, the hand places green basil leaves on top of the cheeses. The skillet remains centered on a wooden board with a red checkered cloth visible in the top right. The camera maintains a top-down view throughout.

Hand moving to place ricotta cheese, parmesan cheese, and basil leaves onto the pizza; cheese and basil leaves are discrete solid objects being physically moved by the hand.

Static wooden surface and red/white checkered cloth background with no shifting or environmental motion (no fire, water, smoke, or wind).


Four individuals sit around a wooden table with scattered playing cards; a person in gray pants reaches toward the table, picks up multiple cards, and arranges them face-up while another individual in dark clothing adjusts their position. The table remains central as cards are redistributed, and the camera maintains a static top-down perspective throughout.

Multiple people are moving: one person in the center shifts from sitting to standing and back, another person in the background moves around the table.

The background (room, furniture) is static with no uniform shifting. No fire, water, smoke, or wind motion observed.


Two men in white uniforms with red and green accents perform dynamic martial arts movements on a wooden floor. They begin in crouched stances, then bend low, extending limbs toward the ground, followed by acrobatic spins and kicks. Other individuals in similar uniforms stand around them, observing. The camera maintains a close perspective, slightly shifting to follow the main subjects' motion.

Discrete human subjects (practitioners in martial arts uniforms) are engaged in dynamic movements including kicks, dodges, and acrobatic maneuvers, demonstrating locomotion and collision-like interactions.

The background consists of static human figures in white uniforms and a smooth reflective floor, with no visible shifting or fluid environmental motion (fire, water, smoke, wind).


A person wearing a red and white striped shirt and dark pants swings an object overhead, then walks forward and bends down to retrieve it. The setting is a grassy field bordered by a fence with distant mountains under a cloudy sky. The camera remains stationary at ground level, capturing the subject's movements from a low-angle perspective.

The golfer (a person) is moving: preparing for a swing, swinging, walking, and bending down. Motion is due to locomotion and club swinging.

No shifting backgrounds or fluid/environmental motion. The background (fence, trees, sky) is static with no wind or fluid effects.


Two women dance energetically in a living room; one wears a white top and black shorts, the other a silver sequined dress. They move in sync, raising arms, stepping side-to-side, and swaying rhythmically. Throughout, the woman in white occasionally gestures with her right arm while the other shifts her stance, maintaining close proximity. The camera remains stationary, capturing them from a frontal perspective with a slight shake.

Two people (solid objects) are moving: one is putting on a jacket and moving, the other is dancing and moving around.

The room background (walls, furniture) is static; no fluid or environmental motions (fire, water, wind) are present.


Three individuals in white karate uniforms with black belts stand around a wooden board; one holds the board while the other two face it, with the rightmost person bending forward to adjust their stance. The person on the far left appears to photograph the scene. The background includes a white wall and stacked chairs, with the camera maintaining a stationary perspective throughout.

A person in a white karate uniform (black belt) moves toward a wooden board, executing a kick that causes the board to move. Other individuals stand stationary.

Background elements (white wall, metal chairs) show no uniform shifting or fluid motion (no fire, water, smoke, or wind visible).


A seated man in a blue tank top and black shorts lifts dumbbells from his lap up to shoulder height, repeating the motion; a woman in athletic wear walks on a treadmill in the background to his right. The camera maintains a fixed perspective throughout.

A person in a blue tank top is performing a dumbbell exercise (lifting weights), with clear motion of their arms and torso due to physical exertion. Other individuals in the background are stationary or minimally moving.

The background includes static gym equipment, walls, and a TV screen with no visible shifting or fluid motion. No fire, water, or wind-driven effects are present.


Two individuals in white shirts, one wearing black pants and the other dark shorts, move within a spacious room with yellow walls and tiled floors. The person on the left begins stepping forward while the right individual walks toward them, maintaining a distance. The camera remains stationary with slight movement, capturing their interaction from a fixed perspective.

Two human figures are moving through the space with distinct locomotion (dancing/walking) visible in their bounding boxes.

Background elements (walls, doors, chairs) remain static with no uniform shifting or fluid motion (fire, water, smoke).


The video opens with a stationary view of a residential driveway featuring a basketball hoop, green trash bin, and houses. A person wearing a black t-shirt enters the frame from the right, holding a basketball. They move the ball closer to the camera, displaying its surface, then step out of the frame, leaving the driveway scene visible. The camera remains fixed throughout.

A person (discrete object) enters the frame from the right, moves left across the frame, holds a basketball, and then exits the frame to the right. The basketball is moved by the person.

The background (sidewalk, basketball hoop, plants, building) is static throughout the video. There is no evidence of fire, water, smoke, or wind (leaves do not sway, no movement in the environment).


tags.  So final answer:  <caption_output>A person wearing a blue and white striped shirt and pink earphones holds a red and white lollipop, bringing it toward their mouth, inserting it, and sucking on it. The camera maintains a close-up perspective throughout.

A person is holding and rotating a lollipop in their mouth; the lollipop and the person's hand/mouth are moving due to explicit physical actions.

The background (wall) is static with no shifting or fluid/environmental motion (fire, water, wind).


A hand gathers thinly sliced onion rings on a wooden cutting board, then uses a large chef's knife to slice through the stack, moving the knife downward. The hand holds the onion firmly while the knife cuts through the layers, accumulating sliced pieces on the board. The camera maintains a close-up, steady perspective focused on the cutting action.

Person's hands and knife are moving to chop onions; motion results from explicit physical forces (knife impacting onions causing slicing and displacement).

Background elements (sink, countertop) are static with no shifting or fluid motion. No fire, water, smoke, or wind observed.


A person in light-colored clothing sits at a wooden table with various items, then moves their arm to interact with objects on the table before standing and walking away from the table; the camera maintains a top-down view with slight shake.

A person is moving around the table and under it, demonstrating locomotion.

The background (walls and floor) is static and does not shift uniformly. No fire, water, smoke, or wind is present.


A hand enters the frame from the bottom right, holding a pen, and begins coloring the blue section of the left character on a white paper. The hand moves steadily across the character's body while the right character remains uncolored. The camera maintains a fixed top-down perspective throughout.

A hand (discrete solid object) is moving to draw lines on the paper, creating visible motion as it sketches details on the cartoon characters.

The background consists of a static white paper with two cartoon characters; no shifting backgrounds or fluid/environmental motion (fire, water, wind) is observed.


A person wearing a pink sleeveless shirt, black shorts, black boots, and a hat rides a hoverboard with red wheels, holding a grass trimmer. They move slowly from left to right across a grassy lawn in front of a stone house with bushes. The camera pans slightly to follow their motion.

The person (wearing pink shirt, black shorts, and hat) is moving a lawnmower across the grass. The motion is due to the person's locomotion.

The background (house, bushes) is stable without uniform shifts. There is no dominant fluid or environmental motion (fire, water, smoke, wind).


A person with long dark dreadlocks and a light-colored top moves closer to the camera in a room with a ceiling light and metal rack visible in the background; they smile and raise their right hand to touch their face. The camera maintains a close-up perspective with slight handheld movement.

A person is moving their head and hand, with discrete motion that is not camera-induced or environmental.

Background is stable (white wall and ceiling fixtures remain fixed); no environmental fluids (fire, water, smoke, wind) detected.


The video opens with a close-up of a person in a green shirt with a dark floral-patterned collar, partially obscured by a colorful patterned cloth. It transitions to an older woman with short dark hair and glasses, also wearing a green shirt with a dark floral-patterned collar, seated at a table covered with a vibrant multi-colored fabric. She meticulously embroiders a cloth with a needle and thread, her hands moving steadily. The background includes household items like a wooden chair and woven baskets. The camera shifts from the initial close-up to a side view of the embroidering woman, maintaining a steady focus on her hands and the detailed work.

Person's hands and needle exhibit discrete motion while sewing fabric; movements are controlled locomotion (hand manipulation) and collisions (needle piercing fabric). The sewing machine components also show localized motion.

No shifting backgrounds or fluid/environmental motion (fire, water, wind). Background elements (wall, fabric rolls, chair) remain stationary throughout the sequence.


RAW CAPTION: Got it, let's tackle this. First, the video shows a band on stage. Let's list the subjects: five people. The main actions are them playing instruments. The girl on the left is singing or playing, then the guy with guitar, then the one with banjo (cowboy hat), then the singer with sheet music, and the drummer in back.

Chronological order: they start playing. The girl on the left is holding a mic, the guitarist strums, the banjo player strums, the singer in white shirt reads from sheet music, drummer plays. The stage has an American flag, but minimal background. Camera seems to pan slightly, maybe moving a bit. Let's check the rules: no text recognition, so ignore the signs. Focus on motion and behavior.

First, describe the band members' actions in order. The girl is on the far left, holding a mic, possibly singing. Then the guy next to her with a guitar, strumming. Then the cowboy-hatted person with banjo. Then the guy in white shirt with sheet music, singing. The drummer on the right is playing. The camera moves slightly, maybe panning from left to right? Wait, the video clips show the camera angle changing a bit, maybe a slight pan.

So, the main subjects: five musicians. Their actions: playing instruments (guitar, banjo, drums, singing), moving their hands. The spatial relationships: the girl is leftmost, then guitarist, then banjo player, then singer, then drummer. The stage has an American flag in the background. Camera is at a medium distance, slightly panning.

Need to be concise. Let's structure it: "A band of five musicians performs on stage; from left to right, a woman in a black dress sings into a microphone, a man in a blue plaid shirt strums a guitar, a man in a red shirt and cowboy hat plays a banjo, a man in a white shirt sings while reading from a sheet music stand, and a drummer in the background plays cymbals and drums. The camera pans slightly across the stage as the musicians continue their performance." Wait, but check the rules: no text recognition, so don't mention "POAKEY" sign. Also, describe appearance briefly: color, size, orientation.

Wait, the woman: black dress, short hair. Man in blue plaid: medium height, holding guitar. Man in red: cowboy hat, playing banjo. Man in white: singing. Drummer: maybe behind, playing.

So, "Five musicians perform on stage: a woman in a black dress with short hair stands left, singing into a microphone; a man in a blue plaid shirt holds a guitar, strumming; a man in a red shirt and cowboy hat plays a banjo; a man in a white shirt sings from a sheet music stand; and a drummer behind them plays cymbals and drums. The camera pans slightly left to right during the performance, capturing the group’s synchronized playing and singing."

Wait, but need to be chronological. The video starts with them playing, so the actions are ongoing. The camera movement is slight. Let's check the initial frames: the first frame shows them, then the camera shifts a bit, maybe panning. So the camera movement is a slight pan.

Also, spatial relationships: the woman is leftmost, then guitarist, then banjo player (middle), then singer, then drummer. Background is an American flag, but minimal description.

Final caption should be concise. Let's trim: "A five-person band performs on stage; a woman in a black dress sings leftmost, a man in a blue plaid shirt plays guitar, a man in a red shirt and cowboy hat strums a banjo, a man in a white shirt sings while reading sheet music, and a drummer plays cymbals and drums in the background. The camera pans slightly across the stage as the musicians continue their performance."

Wait, the video shows the camera moving a bit, so "camera pans slightly". Also, check for excluded elements: no text recognition, so no "POAKEY" sign. Good.

Check all rules: focus on motion and behavior (playing instruments, singing, reading sheet music), chronological order (they're performing), appearance (brief: black dress, blue plaid, red shirt, white shirt, drummer's position), spatial relationships (left to right order), camera movement (panning), background minimal (American flag not described in detail).

Yes, that should work.

Band members (e.g., guitarist, drummer, singer) exhibit subtle movements from playing instruments and body swaying, consistent with discrete solid-object motion due to physical interaction with instruments.

The background features a static American flag and stage elements with no visible shifting or fluid motion (fire, water, smoke, wind).


A woman in a black dress plays a red drum set with drumsticks, striking cymbals and drums rhythmically while seated in front of the instrument; the background includes a wooden structure and red carpet, with minimal movement from the camera that remains stationary.

The drummer's arms and hands move rhythmically to strike the drum kit, causing discrete physical interactions (drumstick collisions with drums/cymbals) and vibration of the drum surfaces.

The background elements (walls, wooden structure, red carpet) remain static with no shifting or environmental fluid motion (fire, water, smoke, wind).


A hand holds a small white espresso cup on a matching saucer beneath an espresso machine, tilting the cup to pour the dark coffee into the saucer. The hand then lifts the cup, revealing the emptying process, with the cup’s interior and the remaining coffee visible. The camera maintains a close-up perspective throughout, focusing on the cup and hand’s motion against a dark, minimally detailed background.

A hand moves a white cup of coffee; the cup is a discrete solid object whose motion is driven by the hand's locomotion.

The background elements (coffee machine, glass, and surface) remain static with no uniform shifting, and no fluid/environmental motion (e.g., fire, water, wind) is present.


A man in a white tank top, blue jeans, and yellow shoes pushes a green lawnmower with yellow wheels across a grassy yard, moving from near the porch column toward the right. The camera pans right to follow his mowing motion as he progresses across the lawn.

A person wearing a white tank top, jeans, and red cap is mowing the lawn with a lawnmower, moving from left to right across the grass. The lawnmower and the person are solid objects with distinct bounding boxes.

The background elements (house, trees, parked cars, road) show no uniform shifting or fluid motion. No fire, water, smoke, or wind is visible.


Two girls sit at a table; the girl on the left, wearing a black top and having long dark hair, initially touches her face, then moves her hands to her mouth to blow into a small object, while the girl on the right, in a patterned shirt, inflates a large red balloon held in front of her. The camera remains stationary.

The red balloon inflates due to the person on the right blowing air into it; the person on the left blows into a small whistle and moves their hands.

No shifting backgrounds; static wall and chair elements remain unchanged. No fire, water, smoke, or wind as dominant motion.


Hands manipulate a stack of playing cards against a dark background, initially fanning and separating cards. The hands move cards from one pile to another, then shuffle and display a card with a spade symbol. The camera maintains a top-down perspective throughout, focusing on the hands and cards with minimal background detail.

Hands are manipulating solid playing cards, performing actions like shuffling, separating, and displaying individual cards.

The background is a uniform black surface with no visible shifting or fluid motion (e.g., no fire, water, smoke, or wind).


RAW CAPTION: Got it, let's break this down. First, the video shows a person playing a keyboard. Let's check the rules. The main subject is the person, so describe their actions chronologically.

Start: Person is sitting on a bed, wearing a blue sleeveless shirt and black shorts with white stripes. They're playing the keyboard. Then, in the next seconds, they stop playing, stand up, and move away from the keyboard.

Appearance: Male, short hair, blue shirt, black shorts with white stripes. Position: sitting on bed with striped pillow, keyboard in front. Then stands up and leaves the frame.

Spatial relationships: Keyboard is in front of the person, bed has pillows. Background is a room with a wall, some items like a blue pillow, maybe a chair.

Camera: The video is static? Wait, the video shows the person moving, but the camera doesn't seem to move. Wait, the frames might have a slight shake, but the problem says "conclude with camera perspective and movement". Let's see: the camera is fixed, maybe a slight shake but mostly static.

Wait, the rules say: "Conclude with the camera perspective and movement". So need to mention if it's fixed, pan, etc.

Let's structure:

- Initial scene: person sitting on bed, playing keyboard. Description of their clothes, position relative to keyboard.

- Then: they stop, stand up, and leave the frame.

- Background: minimal, so just mention the bed, pillows, wall.

- Camera: static or slight shake?

Looking at the video frames: the camera doesn't move, so fixed. But maybe slight shake? The problem says "if relevant".

So putting it all together:

A person wearing a blue sleeveless shirt and black shorts with white stripes sits on a striped pillow on a bed, playing a keyboard. They then stand up, move away from the keyboard, and exit the frame. The keyboard is positioned in front of them, with a blue and white striped pillow behind. The camera remains fixed throughout the sequence with slight shake.

Wait, need to check rules: keep background minimal. So maybe just the bed, pillow, but not too much. Let's see.

Rule e: "Keep background descriptions minimal unless essential for understanding motion." So the bed and pillows are part of the scene where the person is sitting, but maybe not essential for motion, but the motion is moving off the keyboard, so maybe the bed is necessary as their initial position.

Let me structure the caption:

A young male, dressed in a blue sleeveless shirt and black shorts with white stripes, sits on a striped pillow on a bed, playing a keyboard placed in front of him. He then stands up, turns away, and moves out of the frame. The camera remains stationary with minimal movement throughout the sequence.

Wait, but the problem says "chronological paragraph". So sequence of actions.

First action: sitting, playing. Second: stops, stands up, moves away.

Now, check the appearance: "male" but the video shows a person, maybe "a person" but rule b says "briefly describe their appearance and number (color, size, orientation)". So "a person" but maybe specify gender if visible. The video shows a boy, so "a boy".

Wait, the rules don't specify gender, but if it's visible, include. The first frame: "boy" as the person.

So:

A boy wearing a blue sleeveless shirt and black shorts with white stripes sits on a striped pillow on a bed, playing a keyboard. He stops playing, stands up, and moves out of the frame. The camera remains fixed throughout the sequence with slight movement.

Check rules: exclude text recognition, so no text. Conclude with camera perspective: fixed. Movement: slight shake.

Wait, the video's camera: the frames might have a slight shake, but the problem says "DO NOT output reasoning", so just note if it's fixed.

Wait, the sample output should be concise. Let's try:

A boy in a blue sleeveless shirt and black shorts sits on a striped pillow on a bed, playing a keyboard. He stands up, turns away, and exits the frame. The camera remains stationary with minor shake.

Yes, that's concise. Let's check rules:

a) Motion and behavior: chronological (sitting, playing, standing up, moving out).

b) Appearance: blue shirt, black shorts, striped pillow.

c) Spatial: keyboard in front, pillow behind? Wait, "sits on a striped pillow on a bed" so spatial: pillow on bed.

d) Camera: stationary with minor shake.

e) Background minimal: bed, pillow, but maybe not too much.

f) No text.

g) Don't include reasoning.

So the caption would be:

<caption_output>A boy wearing a blue sleeveless shirt and black shorts

The person (a discrete solid object) is moving: initially seated playing the keyboard, then standing and walking away from the keyboard.

The background (bed, pillows, wall) is static with no fluid or wind-driven motion. No camera-induced motion detected.


A person wearing a yellow and black life vest and blue shorts sits on a small white sailboat with a purple and blue sail, adjusting the sail and oar while the boat glides forward on calm water. The camera follows the boat from behind, panning left as it sails past a tree-lined shore.

A person on a sailboat, moving the boat via sail manipulation.

Background trees are static; water has minor ripples but not dominant ambient motion.


A person in a light gray t-shirt strums a black electric guitar, their hands moving across the fretboard and strings. They stand in front of a wooden wall, with a second guitar visible to the right. The camera remains static throughout.

Person's hands moving on guitar strings (explicit physical interaction with instrument; discrete solid object motion).

Wooden wall and static equipment in background show no uniform shifting; no fire, water, smoke, or wind motion detected.


A man in a yellow shirt and blue jeans polishes a small, dark wooden table with three legs. He steps back, walks away from the table, which rests on a green cloth. The camera pans slightly to focus on the table's position after his departure.

The person is moving: adjusting the table, walking away, and shifting posture. The table is stationary on a green cloth, but the person’s locomotion is distinct.

Static background elements (shelves, walls, floor) show no uniform shifting or fluid motion (no fire, water, smoke, wind).


A person wearing a red shirt holds and plays a golden saxophone, their mouth positioned on the mouthpiece; after a few seconds, they stop playing, turn their body to the left, and walk out of the frame. The camera remains stationary, capturing the individual against a plain wall with a radiator visible to the right.

A person (discrete solid object) moving by locomotion while playing a saxophone, then walking out of frame.

The background (radiator and chair) is static and does not shift uniformly; no environmental fluid motion observed.


A child in a white shirt and white pants is initially prone on muddy ground, then pushes up with their arms, rolls onto their back, and moves forward on their hands and knees. The camera maintains a top-down perspective with slight shake.

Two individuals in white clothing are wrestling on the ground. Their motion is due to physical forces (grappling, pushing, lifting) and can be tracked as distinct solid objects.

The background (muddy ground with dry leaves) shows no fluid motion (water, fire, smoke) or wind-driven elements (trees swaying). The ground is mostly static with no uniform shifting of background elements.


A person in a dark shirt and light shorts begins crouched near orange cones on an indoor basketball court. They sprint forward, dribbling a basketball while weaving around the cones, moving across the court past the center court logo and toward the basketball hoop against red walls. The camera follows the subject's motion throughout.

A basketball player (solid object) and basketball (solid object) move due to dribbling, running, and ball-handling actions.

The red walls and wooden basketball court floor remain static across frames; no fluid motion (fire, water, smoke, wind) is present.


RAW CAPTION: Okay, let's tackle this video captioning task. First, I need to understand the requirements. The user provided a video snippet with a title screen followed by a scene of a room with people playing saxophones.

The main rules are to focus on motion and behavior in chronological order, describe appearance and number, mention spatial relationships, conclude with camera perspective, keep background minimal, exclude text recognition, and avoid named characters.

Starting with the video: The first part is a black screen with text, but the rules say to exclude text recognition, so I shouldn't mention the text. Then the scene shifts to a room with many people. The caption needs to describe the main subjects (people playing saxophones), their actions, number, appearance (but keep it brief), spatial relationships, and camera movement.

Looking at the video description: There's a large room with a crowd. They are holding saxophones. The camera is in an overhead shot. The people are standing around, maybe in groups. I need to note the number—since it's "the most saxophone players," but the exact number isn't specified. The caption should mention it's a large group, maybe "multiple saxophonists."

The scene transitions from text to the room. So the chronology starts with the text (but skip that per rules), then the room. The main action is people playing saxophones. Maybe they're arranged in a circle or groups. The camera is top-down, as per the description. The room has chairs and tables, but background should be minimal.

Wait, the user says to exclude text recognition, so even the title isn't mentioned. The caption should start from the scene where people are playing. So first frame is black screen, then the next frames show the room. But the user says "focus on motion and behavior of main subjects in chronological order." So the video starts with the text, but we skip that. Then the main scene is the room.

In the room, there's a large group of people, all holding saxophones. They're standing in a circle or semi-circle? The description says "standing around chairs." Maybe some are playing, some waiting? The caption should mention they are playing saxophones, so their action is playing.

Number: "multiple saxophonists" or "a large group of saxophone players." The appearance: saxophones (color? Maybe assume they're typical colors like silver or black, but since it's a generic description, maybe just "saxophones." Age? Not specified. So "multiple individuals holding saxophones."

Spatial relationships: maybe "arranged in a circle around chairs and tables." The room has chairs, tables, so the saxophonists are in the center or around the room.

Camera perspective: the description says "aerial view," so top-down. The camera is overhead, static or panning? The user says to mention movement. The example output might have "top-down view." The original video description says "an aerial view of the room," so the camera is positioned above, looking down.

The caption should be concise. Let's structure it:

- Chronological order: The scene opens with a group of saxophone players gathered in a room, arranged in a circle around chairs and tables. Multiple individuals (color and size not specified, but assumed typical) are standing, holding saxophones, and playing. They are positioned in various spots within the room, with some near tables. The camera maintains a static top-down perspective.

Wait, but need to follow the rules. The user says "briefly describe their appearance and number." So for appearance: "multiple individuals holding saxophones (likely silver or black)." But maybe better to be generic: "multiple saxophonists holding saxophones." Number: "a large group."

Spatial: "arranged in a circle around tables and chairs."

Camera: "top-down aerial view."

Also, the original video description mentions "aerial view," so the camera is high above. The video ends with this scene.

Putting it all together: The video opens with a black screen, then transitions to an aerial view of a large room where multiple saxophonists stand in a circle around tables and chairs, playing their instruments. The camera remains stationary in a top-down perspective.

Wait, but the first part is a black screen with text, but the rules say to exclude text recognition. So the caption should start from the scene after the text. So the chronology starts with the room scene.

Wait, the user's example says: the first frame is black screen, then text, then the room. The caption should describe the action after the text. So the video starts with the text (but we ignore that), then the scene of the room. So the main caption starts with the room.

So the caption should start with "A large group of saxophonists gather in a room

Multiple people are present as discrete solid objects; their motion appears to be minimal locomotion (standing or slight shifts) without significant collisions or external forces.

The background includes static elements (chairs, tables, walls) with no uniform shifting; no fire, water, or wind-driven motion observed.


RAW CAPTION: Got it, let's break this down. First, I need to observe the video frames. The scene is an indoor gym with a wooden floor. There are several people. Let's list the main subjects and their actions.

In the first frame, a group of people: some in white shirts, one in red. The red shirt person is facing away. There's a pair of shoes on the floor. Then, in the next frames, a person in white (maybe sitting or squatting) comes into view. Then, a person runs in from the right side, kicks the shoes? Wait, the shoes are on the floor. Let's check the motion.

Frame 0: People standing, shoes on floor. Frame 1: A person (white shirt, crouching) on the left. Frame 2: Same, but the person in red is still there, others moving? Wait, the action seems to be someone kicking the shoes. Wait, the shoes are on the floor, then a person runs towards them. Let's see the sequence.

Looking at the video: initially, a group of people (three or four) are standing. One person in red shirt, others in white. Shoes are on the floor. Then, a person in white (left side) crouches. Then, another person (right side) runs towards the shoes, kicks them. Wait, the shoes might be moved. Let's track the movement.

The main actions: a group of people stand near the center. A person in a white shirt crouches on the left. A person in white (from right) runs towards the shoes on the floor, kicks them. Then, the group moves slightly. Need to describe in chronological order.

Appearance: several people, mostly white shirts, one red. Shoes are on the floor. The person kicking is in white shirt, dark pants. Camera is stationary, top-down view? Wait, the camera angle seems to be eye-level, not top-down. The video is in a gym, so wooden floor, walls, some equipment.

So, chronological steps:

- Initial scene: multiple people (two in white shirts, one in red shirt, others) standing in a gym; a pair of shoes lies on the floor.

- A person in a white shirt crouches on the left side.

- A person in a white shirt and dark pants runs from the right side, kicks the shoes, causing them to move.

- The group of people shifts positions slightly.

Background: gym with wooden floors, walls, some blue padding and stacked chairs.

Now, concise paragraph. Must mention motion chronologically.

Check rules: focus on main subjects (people), appearance (color, size, etc.), spatial relationships, conclude with camera.

So: In a gymnasium with wooden floors, a group of people (including one in a red shirt and others in white) stand near the center; a pair of shoes rests on the floor. A person in a white shirt crouches on the left side of the frame. Then, a person in a white shirt and dark pants runs from the right, kicks the shoes, causing them to roll. The group shifts positions slightly as the shoes move. The camera remains stationary with a slightly wide-angle view.

Wait, check minimal background: "gymnasium with wooden floors" is okay. Spatial relationships: "left side of the frame", "right side". Camera: "stationary with a slightly wide-angle view".

Check for rules: no text recognition, no named characters. Correct.

Let's make it concise. Focus on motion.

Alternative:

In a gym with wooden floors, several people (one in a red shirt, others in white) stand near the center where shoes lie on the floor. A person in white crouches left; another in white and dark pants runs right to kick the shoes, which roll. The group shifts positions as the shoes move. The camera stays fixed.

Wait, maybe more precise:

In a gymnasium with wooden flooring, a group of individuals (including a person in a red shirt and others in white) stand near the center; a pair of shoes rests on the floor. A person in white crouches on the left. A person in white shirt and dark pants runs from the right side, kicks the shoes, causing them to roll toward the center. The group adjusts their positions slightly. The camera remains stationary with a wide view.

Check if this is chronological. Yes: initial standing, crouching, running and kicking, then group shifts.

Yes, that's the sequence.
</think>

<caption_output>In a gymnasium with wooden flooring, several individuals (including one in a red shirt and others in white) stand near the center where a pair of shoes lies on the floor. A person in white crouches on the left side of the frame. Another individual in a white shirt and dark pants runs

Multiple people (solid, discrete objects) move due to locomotion (running, positioning) and possible collision dynamics (e.g., volleyball interaction implied by court setup).

Background elements (walls, floor, gym fixtures) show no uniform shifting or fluid motion (fire, water, smoke, wind). Static environment with no environmental fluid dynamics.
