RAW CAPTION: Got it, let's see. The video shows a girl in a room. First, she's holding something near her face, maybe a makeup item. Then she moves her hand, maybe applying something. She has light brown hair, wearing a gray shirt. The background has a "LOVE" sign, red curtains, some toys. The camera is steady, probably a close-up. Let's check the rules. Focus on motion: she starts with hand to face, then moves it. Appearance: girl, gray shirt, long hair. Spatial: room with background elements. Camera: close-up, no movement. Need to be concise, chronological.

So the caption should start with her action, then describe her appearance briefly, mention the room's key elements minimally, and camera perspective. Let's structure it:

A girl with light brown hair and gray shirt is seen in a dimly lit bedroom, holding a small object near her face with her right hand, then moving it away as she looks toward the camera. The room features red curtains, a "LOVE" wall decoration, and scattered toys. The camera remains stationary in a close-up view.

Wait, check rules: exclude text recognition, so "LOVE" is text, but the rule says "Exclude text recognition"—wait, rule f says "Exclude text recognition, named characters, or stylistic analysis." So "LOVE" is text, so maybe don't mention it? Wait, no, the background descriptions should be minimal unless essential. But the problem says "keep background descriptions minimal unless essential for understanding motion." So maybe the "LOVE" is part of the background, but if it's not essential for motion, maybe skip. But the room has a "LOVE" sign, which is a detail. Hmm. The example in the rules says "mention spatial relationships if relevant" and "keep background descriptions minimal unless essential for understanding motion."

So maybe the room's details like the sign are not essential for motion, so skip. Wait, the main motion is the girl's action. Let's see:

In the video, a girl with long, light brown hair wearing a gray shirt is positioned in a dimly lit room. She holds a small object near her face with her right hand, then moves it away while looking toward the camera. The background includes red curtains and miscellaneous items. The camera remains stationary in a close-up perspective.

Wait, but rule e says "keep background descriptions minimal unless essential for understanding motion." So maybe "red curtains" and "miscellaneous items" are minimal. Let's check the original frames: the room has red curtains, a "LOVE" sign, toys. The motion is the girl's hand movement. So background is not essential for motion, so maybe just "a room with red curtains and various objects."

But the instruction says "briefly describe their appearance and number (color, size, orientation)." The girl: light brown hair, gray shirt. Motion: starts with hand to face, then moves. Camera: close-up, no movement.

Let me write:

A girl with light brown hair and a gray shirt is in a dimly lit room, holding a small object near her face with her right hand, then moving her hand away as she looks toward the camera. The room features red curtains and various objects. The camera remains stationary in a close-up view.

Wait, check rule b: "Briefly describe their appearance and number (color, size, orientation)." So the girl's hair color (light brown), shirt color (gray), maybe size? The video shows her as a child, but maybe not specify size. Orientation: she's facing the camera.

Wait, "briefly describe their appearance and number (color, size, orientation)." So "a girl with light brown hair and gray shirt" covers color. Size: since it's a child, maybe just say "a girl".

Motion: chronological order. First, she holds object near face, then moves hand away.

Background: minimal, so "a dimly lit room with red curtains and assorted items" but maybe "red curtains" is part of the background.

Camera: "remains stationary in a close-up view".

Putting it all together:

A girl with light brown hair and a gray shirt is in a dimly lit room, holding a small object near her face with her right hand, then moving her hand away while looking toward the camera. The room has red curtains and miscellaneous objects. The camera maintains a close-up, steady position throughout.

Wait, but the rules say "Exclude text recognition" so "LOVE" sign shouldn't be mentioned. The original has "LOVE" letters, but that's text, so exclude. So background just has red curtains, toys.

Let me check the original frames again. The background elements: red curtains, a "LOVE" wall decoration (which is text), a colorful balloon, a stuffed

The girl is moving: raising hand to face, covering mouth, holding cheek, and head movement (facial expressions and gestures).

Background is static with no shifting elements or environmental fluid motion (e.g., fire, water, smoke, wind).


A person in a blue shirt and khaki shorts operates a floor buffer with a red top and black base, moving it across a blue floor with white streaks. The individual pushes the buffer forward, rotating its head to create swirling patterns on the surface. The camera follows the movement, panning slightly to maintain focus on the action.

A person (wearing blue shirt, khaki shorts) operates a red floor buffer, moving it across the floor in circular patterns; the buffer's motion is driven by human locomotion.

Background elements (blue walls, floor, windows) remain static and consistent throughout; no fire, water, smoke, or wind motion observed.


A white boat with visible seating is in the foreground, while a red and white kayak moves away from the camera through the water, creating a wake. The kayak remains partially submerged as it recedes toward the tree-lined shore. The camera stays steady, capturing the kayak’s departure from the foreground boat.

The red and white boat is moving across the water, exhibiting clear locomotion due to its own propulsion (e.g., engine), with visible wake formation.

The water shows ripples from the moving boat (ambient_environmental), while the tree-lined shore remains static and does not shift uniformly, indicating no dominant fluid or environmental motion overwhelming the scene.


Two individuals sit side by side; the person on the left, wearing a black shirt and cap, plays a saxophone with their mouth on the mouthpiece and hands on the keys, while the shirtless person on the right strums a guitar with their hands on the fretboard. They remain seated in fixed positions throughout, with the camera maintaining a stationary perspective exhibiting a slight shake, capturing their instrumental performance against a minimal indoor background.

Two individuals (saxophonist and guitarist) exhibit deliberate motion through instrument playing; their bodies and limbs show controlled displacement consistent with physical interaction with instruments.

Background elements (walls, fabric) remain static with no uniform shifting or fluid motion (fire, water, smoke, wind) observed.


A shirtless man in gray shorts and black shoes lifts a barbell with weights from shoulder height overhead, then lowers it to chest level, bending at the knees. The gym background includes equipment racks to the left. The camera remains stationary throughout.

The man (discrete object) is performing a barbell lift: raising the barbell overhead and then lowering it. The barbell itself is a solid object moving under explicit physical force (muscle exertion).

The background (walls, door, and rack) is static and shows no shifting or environmental motion (fire, water, smoke, wind). No fluid or gaseous elements are present.


Two white-gloved hands manipulate a small object on a person's skin, pinching and pulling it outward in a sequential motion. The hands adjust their grip and position as they interact with the skin, with the camera maintaining a steady close-up perspective throughout the sequence.

Gloved hands manipulate a small dark object (likely a mole or lesion) on the skin; the object and gloves exhibit discrete, solid movement through direct physical interaction.

The background consists of static skin with no shifting elements, fluid motion (fire, water, smoke), or environmental wind effects observed.


A person's hands manipulate a small white box with intricate design, opening it to reveal a deck of cards with black squares on white background. The hands then spread the cards across a green surface with yellow trim, positioning them in a grid pattern. The camera maintains a top-down perspective with no significant movement throughout the sequence.

A person's hands and a deck of cards are moving. The hands perform actions like shuffling, handling the deck, and placing it on the table.

The background elements (couch, table, and miscellaneous items) show no uniform shifting or fluid motion. No fire, water, smoke, or wind is present.


A person in a purple jacket manipulates a mannequin head with long brown hair secured by pink and blue clips, pulling and adjusting the hair while leaning forward; the camera captures the interaction from a close, slightly shaky frontal perspective.

A person (in purple) is actively moving their hands to style a mannequin's hair, causing the hair to move. The mannequin is stationary but the hair is being manipulated.

No significant shifting background or fluid/environmental motion observed. The background (radiator, curtain) remains relatively static.


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' motion and behavior. Let me look at the video frames provided.

The video starts with a man walking towards a turnstile. He's wearing a white shirt and khaki shorts. The scene is at night, under a Bank of America sign. The camera seems to be moving slightly, maybe panning to follow him. There's a slight shake, which I should mention in the camera perspective.

The man approaches the turnstile, interacts with it—maybe inserting a card or using the machine. Then he moves through the turnstile. The background has some pillars and maybe another person in the distance, but the rules say to keep background minimal. So I should only mention if it's essential. The other person is not the main subject, so maybe skip.

The main subject is the man in white shirt and khaki shorts. His actions: walking towards the turnstile, interacting with it, passing through. The turnstile is between two pillars. The camera is probably at a low angle, maybe handheld, causing a slight shake.

Need to structure the paragraph chronologically. Start with him walking towards the turnstile, then interacting, then moving through. Mention his appearance briefly. The camera movement is a slight shake, maybe panning left. Wait, in the frames, the camera seems to follow him as he moves towards the turnstile. So maybe the camera is panning left to track his movement.

Check the rules again: exclude text recognition (like Bank of America sign), so don't mention the sign. But the sign is part of the background, which is minimal. Wait, the rules say "keep background descriptions minimal unless essential for understanding motion." The sign might not be essential, but the turnstile is part of the structure. Hmm, but the user said exclude text recognition, so the red sign with text isn't mentioned. So focus on the turnstile as an object.

Wait, the problem says "Exclude text recognition, named characters, or stylistic analysis." So even if the sign says Bank of America, don't mention it. So the only background elements that are relevant are the turnstile structure, the pillars, maybe the ground. But keep it minimal.

So the caption should be: A man in a white shirt and khaki shorts walks toward a turnstile, interacts with it, then passes through. The camera follows his movement with slight shake. The background includes a covered area with pillars.

Wait, but the rules say to mention spatial relationships if relevant. So he's approaching the turnstile between two white pillars. The turnstile is part of the structure. Let me check the frames again.

Frame 0: Man is walking towards the turnstile. Frame 1: He's closer, interacting with the machine. Frame 2: He's at the turnstile, moving through. Frame 3: He's passing through. Frame 4: He's exiting the turnstile area.

So chronological order: The man walks towards the turnstile, interacts with it (maybe inserting a card or pressing buttons), then moves through the turnstile.

His appearance: white shirt, khaki shorts, medium build. The turnstile is metallic, white pillars.

Camera perspective: the video starts with a view from slightly low angle, following the man as he approaches, with a slight camera shake. Since it's a handheld shot, maybe the camera moves slightly as the man walks.

Wait, the first frame shows the man walking towards the turnstile. Then the next frames show him getting closer. So the camera is following his movement, maybe panning left as he walks.

But according to the rules, the camera movement should be mentioned in the conclusion. So the caption should end with "Camera follows the subject with slight shake."

Wait, the user says "Conclude with the camera perspective and movement (e.g., top-down, pan left, slight shake)."

So the camera is probably handheld, maybe a slight shake and panning left as the man moves.

Let me structure it:

A man wearing a white shirt and khaki shorts walks toward a turnstile between two white pillars, interacts with the machine, and proceeds through it. The camera follows his movement from a low angle with a slight shake.

But need to check if "interacts with the machine" is accurate. In the video, he's probably turning the handle or inserting a card. But the exact action isn't clear, but "interacts" is safe.

Also, the background is a covered area with pillars, but minimal background description. So maybe mention "a covered area" but the rules say minimal. If not essential, skip.

The main points: man in white shirt, khaki shorts, walking to turnstile, interacting, passing through. Camera follows with slight shake

A person (solid, distinct object) is moving: standing at an ATM, turning, interacting with the machine, and walking away. Motion is due to locomotion (walking) and manual interaction.

The background (walls, pillars, signage) is stationary with no shifting or environmental fluid motion (e.g., fire, water, smoke). No wind or fluid effects are visible.


Initially, a light surface displays colored paint marks: a small blue dot left, a large red blotch center, a white with pink dot top right, and a pink smear bottom. A hand with a paintbrush enters from the left, moves toward the white and pink dot, and touches it. The camera remains stationary in a top-down view.

A hand (solid object) is moving to interact with the paint, causing the paint to spread and mix.

The background is a static white surface with no shifting or environmental motion (e.g., no fire, water, wind).


A person wearing a white polka-dot shirt and colorful bracelets uses a flexible vacuum hose inside a car, moving it along the door frame and lower interior panel. Their hand guides the hose from the upper door area toward the seat, adjusting its position as they clean. The camera maintains a close-up perspective, following the hand and hose motion with minimal background visibility.

A person's hand and a flexible vacuum hose are moving as the hand manipulates the hose against the car door, demonstrating discrete solid-object motion.

The background elements (car interior, steering wheel, window) remain static with no uniform shifting or fluid motion; no fire, water, smoke, or wind is present.


In a gym, a man in a blue shirt and red shorts crouches beside two individuals lying prone on the floor. The first individual wears a blue shirt, black shorts, and blue/yellow sneakers, with hands on the ground; the second wears a gray shirt, black shorts, and red sneakers. The man gestures toward them, then the gray-shirted individual lifts their body slightly, while the blue-shirted individual adjusts their position. The scene is viewed from a static top-down perspective.

Two individuals on the floor (one in blue, one in gray) and a person in blue are moving; the person in blue appears to be performing a dynamic motion (e.g., stretching, exercise), while the others are relatively static or adjusting position.

The background (wooden wall, gym equipment, floor) shows no uniform shifting or fluid/environmental motion (fire, water, smoke, wind). No dominant ambient phenomena observed.


Three people, including one in a gray patterned hoodie, walk from a green dumpster toward a white corrugated metal door. The individual in the gray hoodie moves between two others—one in a black jacket and one in a green jacket—as they approach the door as a group. The camera follows their movement with a slight pan.

Three people are moving: initially at the dumpster (0-0.4 seconds) then walking towards the white container (0.5-5.0 seconds). Their motion is due to locomotion.

The background (white container, yellow post) is static and does not shift uniformly. No fire, water, smoke, or wind is visible.


A person in a white shirt and dark pants stands on a concrete throwing platform, swinging a discus in a circular motion before releasing it. Behind them, another individual in light clothing observes. The scene takes place on a grassy field bordered by a fence and red triangular flags; the camera remains stationary throughout, capturing the thrower's movement from a frontal perspective.

The athlete (person) and hammer are discrete objects. The athlete performs rotational motion (spinning and releasing) driven by physical forces, while the hammer moves as a solid object under the athlete's control.

Background (fence, wall) is static with no uniform shifting. No dominant fluid/environmental motion (e.g., fire, water, wind); flags show minimal swaying but are not the primary motion.


A dealer in a white shirt, black vest, and bow tie shuffles a deck of cards behind a red blackjack table. He then deals the cards onto the table's surface, arranging them in front of him. The camera remains static, capturing the dealer's actions from a frontal perspective with the casino interior in the background.

The dealer (a person) moves their hands and body to deal cards and handle chips; the chips and cards on the table also exhibit motion due to the dealer's actions.

The background (casino setting with walls, fireplace, and floor) is static; no significant fluid or environmental motion (fire, water, smoke, wind) dominates the scene. The fireplace fire is a minor, non-dominant element.


RAW CAPTION: Got it, let's break this down. The video starts with a cake on a stand. First, the cake is white with orange decorations on top. Then, a person enters the frame—they're wearing a gray shirt with "PINK" visible. They're holding a piping bag with chocolate, and they start drizzling chocolate around the top edge of the cake. The chocolate drips down the side. The person's hands are visible, and they're working on the cake's side. The background is a kitchen with cabinets and a sink. The camera is stationary, maybe slightly shaky. Need to capture the chronological order: cake shown, person adds chocolate, chocolate drips. Keep it concise, mention the main actions, appearance (white cake, orange decorations, chocolate drizzle), spatial relationships (person to the right, near the cake). Background minimal, but maybe mention kitchen elements briefly. Let's structure it: start with the cake, then the person adding chocolate, the chocolate dripping, camera perspective.

Check rules: focus on motion/behavior, chronological. Main subjects: cake, person. Describe appearance: white cake, orange rosettes, chocolate being drizzled. Person in gray shirt, hands adding chocolate. Spatial: person enters from right, working on the cake. Background: kitchen (sink, cabinets) but minimal. Camera: stationary, slight shake maybe.

Let's draft:

A white frosted cake with orange rosette decorations on top sits on a stand in a kitchen. A person wearing a gray shirt enters the frame from the right, holding a piping bag with chocolate; they apply chocolate along the cake’s top edge, causing drips down the side. The cake remains centered, with the person’s hands moving around the base. The camera is stationary with minimal movement.

Wait, check rules: exclude text recognition (so "PINK" on shirt is out), named characters (no, person is generic). Focus on motion: person adds chocolate, drips. Appearance: white cake, orange decorations (rosettes), chocolate drips. Spatial: person to right of cake, working on it. Background minimal: kitchen visible, but not detailed. Camera: stationary, maybe slight shake.

Refine:

A white frosted cake with orange rosette decorations on top sits on a stand. A person enters the frame from the right, their hands holding a chocolate piping bag; they drizzle chocolate along the cake’s top edge, resulting in chocolate drips down the side. The cake remains centered as the person adjusts the bag. The camera is stationary with slight movement.

Wait, the first frame shows the cake alone, then person comes in. So chronological: cake present, person adds chocolate. The person's shirt has text but we can't include text recognition, so just say "person wearing gray shirt" (but rule f says exclude text recognition, so maybe just "person" without shirt color? Wait rule f: exclude text recognition. So even if the shirt has text, we don't mention it. So "a person" is okay, no mention of shirt color or text.

Wait, rule f: Exclude text recognition, named characters, or stylistic analysis. So the shirt's "PINK" is text recognition, so we can't mention. So just "a person" enters. Let's adjust.

"A white frosted cake with orange rosette decorations on top sits on a stand in a kitchen. A person enters from the right, their hands holding a piping bag with chocolate; they drizzle chocolate along the cake’s top edge, causing chocolate to drip down the side. The person adjusts the piping bag while working on the cake’s side. The camera remains stationary with slight movement."

Check rules: a) motion/behavior chronological: cake shown, person adds chocolate, drips. b) appearance: white cake, orange rosettes, chocolate. c) spatial: person enters right, works on cake. d) camera: stationary, slight movement. e) background minimal (kitchen mentioned, but necessary for context maybe). f) exclude text (so no shirt details). g) no reasoning.

Another angle: the person is using a piping bag to add chocolate, so the action is applying chocolate. The video starts with cake, then person adds chocolate. So:

The video opens with a white frosted cake topped with orange rosettes on a stand. A person enters from the right, applying chocolate with a piping bag to the cake’s top edge, causing drips down the side. The person moves their hands around the cake’s perimeter, adjusting the chocolate application. The camera remains stationary throughout.

Check: chronological, main subjects (cake, person), motion (applying chocolate, drips), appearance (white cake, orange rosettes, chocolate), spatial (person from right, near cake). Background: kitchen (but minimal, just mention it as setting? But rule e says

A person's hands (discrete solid objects) enter the frame to apply chocolate to the cake, causing visible motion and drips.

Background elements (cabinets, countertop) remain static with no uniform shifting; no fire, water, smoke, or wind motion observed.


A rider in a checkered shirt and dark pants sits atop a brown and white camel as it rotates clockwise on a platform. The camel lowers its head and turns, with the rider holding on securely. The background shows indistinct onlookers, and the camera captures the circular motion from a frontal perspective with slight shifts to follow the camel's rotation.

A mechanical bull (solid object) and its rider exhibit discrete motion: the bull rotates and tilts cyclically, while the rider maintains position relative to the bull.

Background elements (railings, banner, distant people) remain static and do not shift uniformly; no fluid/environmental motion (fire, water, smoke, wind) is present.


RAW CAPTION: Got it, let's break down the video. First, the scene is outdoors on a grassy area with trees and bushes in the background. There's a person standing in front of a large circular metal target mounted on a frame. The person is holding a long pole or stick. They swing the pole, hit the target, and then the pole falls. Wait, the person moves towards the target, swings the pole, then steps back. Let's check the frames:

Frame 0: Person standing, holding pole, target in front.

Frame 1: Person starts moving, swinging the pole.

Frame 2: Person is mid-swing, pole hitting the target.

Frame 3: Person is after the swing, pole is on the ground maybe? Wait, the description says "the pole falls" or is it that the pole is used to hit the target, then the person steps back.

Wait, the video shows the person swinging a long pole at a large black circular target. They move from their initial position, swing the pole towards the target, make contact, then the pole goes off to the side. Then the person steps back. Also, in frame 4, the person is standing back, and a dog runs in. But the task is to describe motion chronologically.

So main subject: person. Appearance: wearing a gray top, blue jeans. Target: large black circular, mounted on a frame. Action: person holds a long pole, moves to swing, strikes the target, then the pole falls to the ground, person steps back. Then a dog enters.

Wait, the frames: [0] person standing, pole in hand. [1] person starts moving towards target. [2] person swings pole, hitting target. [3] person is after swing, pole is near target. [4] person is back, pole on ground. [5] dog enters.

But the rules say focus on motion and behavior of main subjects. The main subject is the person. Let's structure:

A person wearing a gray top and blue jeans stands on a grassy area in front of a large black circular target mounted on a metal frame. They hold a long pole, swing it towards the target, making contact, then step back as the pole falls to the ground. A dog enters the frame from the left.

Wait, need to be concise, chronological. Let's check each frame:

0: person standing, holding pole.

1: person moves to swing pole towards target.

2: person swings pole, strikes target.

3: person completes swing, pole is on the ground (or near ground), person steps back.

4: person stands back, dog appears from left.

So the sequence:

The person, wearing a gray top and blue jeans, stands on grass in front of a large black circular target. They swing a long pole to strike the target, then step back as the pole falls to the ground. A dog runs into the frame from the left.

Now, background: minimal, so just grassy area with trees. But the rules say exclude background unless essential. The target is essential, so mention it.

Let's draft:

A person in a gray top and blue jeans stands on a grassy area in front of a large black circular target mounted on a metal frame. They swing a long pole to hit the target, then step back as the pole falls to the ground. A dog enters from the left.

Check if that's chronological:

1. Person stands in front of target.

2. Swings pole to hit target.

3. Steps back after hitting.

4. Dog enters.

Yes.

Now, camera perspective: the video is from a fixed position, no mention of movement. So "camera remains stationary" or "static shot".

Wait, the rules: "Conclude with the camera perspective and movement (e.g., top-down, pan left, slight shake)."

In this case, the camera is fixed, so "static shot".

So the caption should end with that.

Putting it all together:

A person wearing a gray top and blue jeans stands on a grassy field in front of a large black circular target mounted on a metal frame. They swing a long pole to strike the target, step back, and then the pole falls to the ground; a dog runs into the frame from the left. The camera remains stationary.

Wait, but the dog enters in frame 4. Let's check the frames:

Frame 0: no dog.

Frame 1: no dog.

Frame 2: no dog.

Frame 3: no dog.

Frame 4: dog appears.

So the dog enters after the person steps back.

So the sequence:

Person swings pole at target, steps back, pole falls, dog enters.

Now, in the caption, need to be concise. Let's see:

A person in a gray top and blue jeans stands in front of a large black circular target on

A person moves (walking, swinging a hammer) and a large metal disc (gong) swings due to the hammer impact, both discrete solid objects subject to physical forces.

Static background elements (trees, grass) show no uniform shifting; no fire, water, smoke, or wind motion dominates the scene.


A man wearing a black shirt and blue shorts lies on a blue mat, then sits up, bends his knees, leans back, and returns to a lying position. He is positioned on the mat with arms extended initially, then moving as he shifts. The camera remains stationary throughout.

A person (discrete solid object) performs sit-up movements, demonstrating controlled physical motion through muscle contraction.

The background (posters on wall, floor mat) shows no uniform shifting or fluid motion. No fire, water, smoke, or wind effects present.


The video opens with a person in a light blue shirt seated at a desk, with two WFFY NEWS logos visible behind them. The scene then transitions to another individual wearing a black shirt and orange tie, seated at a desk with a single WFFY NEWS logo positioned to their right. Both individuals remain stationary throughout their respective shots, with the camera maintaining a static position for each segment before cutting to the next.

Two human anchors (solid objects) are moving: the female anchor in the first frame and the male anchor in the subsequent frames, exhibiting subtle hand gestures and head movements.

The background is a static studio set with no shifting. There is no fluid or environmental motion (e.g., fire, water, wind).


In a backyard with a wooden fence and overcast sky, a person wearing a light blue jacket, black pants, and white shoes enters from the left. They hold a badminton racket, move to the center of the frame, and swing the racket to hit a shuttlecock, which is airborne. Another person in a light shirt stands motionless to the right. The camera remains stationary throughout, capturing the scene from a low angle.

A woman is moving (swinging a badminton racket) and a shuttlecock is in flight, both exhibiting discrete physical motion.

The background (brick wall, trees) is stable with no uniform shifting. The sky has clouds moving slowly, but this is not dominant motion (ambient motion is minimal).


RAW CAPTION: Got it, let's tackle this. First, the video starts with a black screen, then transitions to an indoor gym setting. The main subjects are people—there are a few individuals. Let's see the sequence: at 2 seconds, a person in a dark top and light pants is near a sign. Then at 3 seconds, more people appear, including someone in purple and jeans. They move towards the camera or around. The background has wooden walls and a sign, but the main action is the people moving. Camera perspective: it's a bit shaky, maybe handheld, and the view is from a low angle or close to the ground. Need to mention the motion chronologically. So the sequence is: dark screen, then gym with people (number: maybe 2-3), they walk around, interact? The captions should be concise. Let's structure it.

Start: Video begins with a black screen. Then cuts to an indoor gym where several people are visible. A person in dark clothing stands near a sign, followed by others (including someone in purple) walking across the gym floor. The camera is stationary but slightly shaky, capturing the movement from a low angle. Wait, the description says "the camera perspective and movement" at the end. Let's check the rules: "conclude with camera perspective and movement".

So step by step:

- 0-1 seconds: black screen.

- 1-5 seconds: indoor gym, people moving. Let's list the people: initially, a person in dark top and light pants is near a sign. Then two more people (one in purple and jeans, another in light clothes) walk into view, moving towards the camera and then away.

Need to be concise, mention appearance (colors, size—wait, size is vague, maybe just "people" without size unless specified. The video shows people in various clothes: dark, purple, jeans. Number: probably 3-4 people.

Spatial relationships: the person in dark clothes is near the sign, others come into view. Background: wooden walls, gym floor.

Now, put it in chronological order:

The video starts with a black screen, then transitions to an indoor gym where several people are present. A person in dark clothing stands near a sign, followed by a person in purple and jeans and another in light attire walking across the gym floor toward the camera. The camera remains stationary but slightly shaky, capturing the movement from a low angle.

Wait, check the rules: "keep background descriptions minimal unless essential". The gym has wooden walls, which is essential as it's the setting. But the rule says "minimal". So maybe just say "indoor gym" instead of details.

Also, "exclude text recognition"—so the sign is mentioned but not the text on it. So "a sign" is okay.

Let's revise:

The video opens with a black screen, then shifts to an indoor gym where multiple people move. Initially, a person in dark clothing stands near a sign, followed by a person in purple and jeans and another in light clothing walking across the gym floor. The camera remains stationary but slightly shaky, capturing the movement from a low angle.

Wait, the rule b says "briefly describe their appearance and number (color, size, orientation)". So number: "multiple people" or "several people". Appearance: colors (dark, purple, light), but size is not specified, so maybe just "people in dark, purple, and light clothing".

Also, the spatial relationship: "near the sign", then "walking across the gym floor".

Chronological order: the first person is near the sign, then others enter and walk.

Let me check the frames:

[1.4] shows a sign, then [2.5] shows people, [3.6] more people moving.

So:

At the start, a black screen. Then, the scene changes to an indoor gym with wooden walls. A person in dark clothing is near a sign, then additional people (including one in purple and jeans, another in light clothing) walk across the gym floor. The camera is stationary but slightly shaky, capturing the motion from a low angle.

Wait, need to be concise. Let's compress:

The video begins with a black screen, then transitions to an indoor gym where several people move. A person in dark clothing stands near a sign, followed by a person in purple and jeans and another in light clothing walking across the gym floor toward the camera. The camera is stationary but slightly shaky, capturing the movement from a low angle.

Wait, "toward the camera" is from the frames: in frame 3, they are moving towards the camera, then frame 4-5, they walk away. So maybe "walking across the gym floor" without direction.

Let me check the frames again:

Frame 1: black screen.

Frame 2: gym with a sign

Two people (a man and a woman) are walking on the balcony, moving from left to right.

The background (room interior and balcony railing) is stationary; no fire, water, smoke, or wind observed.


A pair of hands manipulates pink yarn with knitting needles; the right needle holds a loop, which is then slipped onto the left needle to form a new stitch, all within a close-up, static shot focusing on the hands against a plain background.

Discrete solid objects: hands performing knitting motion, with yarn and needles moving in precise, controlled movements.

Background elements (plain surface) are static with no shifting or fluid motion observed; no fire, water, smoke, or wind present.


A person with long hair and patterned leggings begins in a handstand position, hands on the floor and feet extended, body arched; they then lower their body into a kneeling position while moving forward, with a light-colored cat lying still on the rug in front of them. The camera remains static at a low angle.

A person performing yoga transitions from a downward dog pose to a kneeling position, demonstrating discrete locomotion.

Background elements (rug, chair, radiator) are static; no shifting or fluid motion observed.


Two men in a dimly lit room; the left man wears a white t-shirt with dark stripes and light pants, the right man a white t-shirt with text and dark pants. The left man raises his arm, turns toward a dark green couch, and reaches toward objects on it. The right man bends forward, head down, over the couch, remaining still. The camera maintains a static position with slight shake, capturing the scene from a medium distance.

Two people are moving a large white blanket. The person on the right bends and handles the blanket, while the person on the left assists. The motion is due to manual manipulation of the blanket.

The background (walls, lamp, furniture) is stable with no shifting or fluid motion. No fire, water, smoke, or wind detected.


A man in a green shirt and dark pants stands up from a chair, holding a large beige megaphone and raising it to his mouth. A lamp with a floral shade sits on a table to his right. The camera remains stationary with slight movement as the man rises.

A person (discrete solid object) is actively moving a megaphone, raising/lowering it while stepping and adjusting their posture.

No shifting backgrounds observed; static elements (lamp, table, wall decorations) remain fixed. No fire, water, smoke, or wind present in the scene.


RAW CAPTION: Got it, let's break this down. First, the video starts with a casino table scene. There are cards and chips. The main action is a hand moving chips and then picking up a card.

Looking at the timestamps: at [0.0], there's a green felt table with cards (7 of clubs, a face card, Ace of hearts, etc.) and red/yellow chips. Then in [1.4], a hand places a chip stack. At [2.5], another chip is moved. Then [3.6], the hand picks up a card (the Queen of Hearts maybe) and moves it away.

Need to describe chronological order. Main subjects: hand (skin tone, fingers visible), cards (colors, suits), chips (red/yellow, cylindrical stacks). Spatial: chips are on the table, cards spread out. The hand moves chips, then takes a card.

Camera perspective: top-down view, no movement mentioned. Background minimal—just the table.

So structure: Start with scene, hand moves chips, then picks up a card. Mention number of chips (stacks), cards' details.

Check rules: a) motion chronologically. b) appearance (chip colors, card suits). c) spatial (hand near chips/cards). d) camera top-down. e) background minimal. f) no text recognition.

Draft: A hand moves two stacks of red-and-yellow poker chips on a green casino table, then picks up a Queen of Hearts card from among scattered playing cards including a 7 of clubs and Ace of spades. The camera maintains a top-down perspective throughout.

Wait, check the video: [0.0] has the cards. [1.4] hand adds a chip (but wait, maybe it's moving existing chips? Wait the first frame shows chips already there, then in frame 2 a hand adds a chip. Then frame 4, hand picks up a card.

Wait the description: [0.0] shows chips (two stacks?), then [1.4] hand moves a chip (so stack becomes three?), then [2.5] another chip, then [3.6] hand picks up a card. Wait the first frame (0.0) has two chip stacks. Then in 1.4, a hand adds a chip to one of the stacks, making it three. Then 2.5, another chip added. Then 3.6, hand picks up a card.

Wait the user's video frames: [0.0] shows two chip stacks. Then [1.4] a hand places a chip on the table (so adding to one of the stacks). Wait no: in frame 0.0, there are two stacks (red/yellow). Then in 1.4, the hand is moving a chip, so maybe stacking. Then 2.5, another chip. Then 3.6, hand picks up a card.

So step by step: initial scene: green table, cards (7 of clubs, Queen of hearts, Ace of hearts, two Aces, 9 of spades), two chip stacks. Then hand moves one chip stack (adds to it, making three stacks?), then another chip. Then hand picks up a card (the Queen of hearts).

Need to mention number of chips: first, two stacks, then adding to make three. Cards: 7 of clubs (black, 7), Queen of hearts (red, Q), Ace of hearts (red, A), 9 of spades (black, 9), Ace of spades (black, A).

In the video, at [0.0], the table has:

- 7 of clubs (black, 7)
- Queen of hearts (red, Q)
- Ace of hearts (red, A)
- 9 of spades (black, 9)
- Ace of spades (black, A)
- Two chip stacks (red/yellow)

Then [1.4]: hand adds a chip (so one stack becomes two, or third stack?) Wait the video shows:

[0.0] two chip stacks.

[1.4] hand moves a chip, so maybe the stacks are now three? Or the hand is adjusting. Wait the first frame shows two stacks. Then in frame 1.4, a hand moves a chip to the right, adding to the first stack? Then frame 2.5, hand moves another chip, maybe to a new stack. Then frame 3.6, hand picks up a card (the Queen of hearts).

So motion: hand adds chips (two more), then picks up a card.

The caption should be concise. Let's structure:

A hand adjusts red-and-yellow poker chips on a green casino table, moving additional chips to form new stacks near existing chip piles, then picks up a Queen of Hearts card

A hand manipulates poker chips and playing cards: stacking chips, moving them to new positions, and arranging cards on the table. These are distinct solid objects in explicit physical interaction with the hand.

No fluid or environmental motion (fire, water, smoke, wind) observed. Background (green table with printed text) is static and unchanging.


In a gymnasium, a person in a white uniform runs toward a red high jump bar, leaps over it, and lands on the mat before moving away. Spectators in white and orange uniforms stand in the background. The camera remains stationary throughout.

A martial artist in white uniform performs a jump and acrobatic flip on the mat, landing safely. Other individuals in the background remain stationary.

Background walls, basketball hoop, and gym floor are stationary with no fluid motion (fire, water, smoke) or wind effects. Static elements show no uniform shifting.


The video opens with a person with dark hair in a car, their head moving and smiling. Next, a person with light hair gestures with their hands while seated. Then, another individual adjusts their position in the car seat. A person with long hair leans forward, followed by another person’s face visible as they sit in the car. The camera remains handheld, shaky, and rapidly shifts between subjects inside the vehicle.

Two people inside a vehicle are moving: they turn their heads, talk, and gesture. These are discrete solid objects moving due to their own locomotion and communication.

The background outside the window (green landscape) is mostly static with minimal and inconsistent movement, indicating no significant ambient environmental motion (fire, water, wind). There are no fluid or gaseous elements. The background does not shift uniformly, so not camera_motion.


A person in dark clothing jumps onto a trampoline, executes a mid-air flip, and lands on the trampoline surface. The camera remains fixed, observing the action from a ground-level frontal view in a wooded setting with minimal background detail.

A human subject is actively interacting with the trampoline via jumping and flipping motions, demonstrating discrete, solid-body physics through physical forces (trampoline elasticity, gravity, collisions).

Background elements (trees, grass, trampoline frame) show no uniform shifting or environmental fluid motion (e.g., no wind-induced tree swaying, water, or smoke).


A person wearing a blue shirt under a blue and black checkered jacket manipulates a blue object with both hands on a wooden table. The hands move apart and together, adjusting the object's position. The background features a dark chair leg to the left and drawers to the right. The camera maintains a fixed, low top-down view focused on the table and hands.

A person (in blue and black striped shirt) is manipulating a blue object (likely a pen or tool) on a wooden table. The hands and blue object show controlled motion due to explicit physical forces.

Background elements (wooden table, chair, monitor) are static with no shifting or fluid motion. No ambient environmental motion (fire, water, wind) detected.


A person in dark clothing feeds a log into a black log splitter, which splits the log into wood chips that accumulate on the ground. The splitter processes additional logs, and the camera pans around the machine, capturing the snow-covered surroundings and a gray truck parked to the right.

A person operates a saw, moving a wooden plank through the saw mechanism; the saw blade and wooden plank exhibit discrete motion due to cutting action.

No shifting background elements (snow-covered ground, buildings, cars remain stationary). No fluid/environmental motion (fire, water, smoke, wind) present.


A close-up shot shows a red pot on a stove with a single frying egg, featuring a white surrounding and yellow yolk, lightly seasoned. A hand briefly enters the frame to adjust the pot's position. The camera then shifts to a wider kitchen scene where a woman with dark hair, wearing a light-colored top, moves toward the stove. She lifts a black frying pan and places it back on the stove, adjusting its position. The kitchen background includes wooden cabinets, a red toaster, and a knife block. The camera remains steady, capturing the woman's actions from a medium angle as she interacts with the stove and pan.

A person (discrete solid object) moves across the kitchen space, performing actions like turning and reaching. The egg in the pan shows minimal thermal motion but is not a distinct moving object due to explicit physical forces.

Background elements (cabinets, stove, utensils) remain static with no uniform shifting or fluid motion (e.g., fire, water, smoke) observed in any scene. The cooking egg is a solid object undergoing thermal change, not ambient environmental motion.


RAW CAPTION: Got it, let's break this down. First, the main subject is a person. Let's describe their actions chronologically. The video starts with the person crouching, holding a tool (maybe a drill or something) into a white container. Then they move the tool, maybe adjusting it. Next, they use a knife? Wait, in the frames, they're handling a stick or drill, then switching to a knife. Wait, the sequence: first, they're using a tool (like a drill bit) on a white container. Then they move the tool, maybe stop, then use a knife to cut or open the container. Then they're holding the knife and the container. Let's check the frames:

Frame 0: crouching, holding a tool (long, thin) into a white cylindrical object.

Frame 1: still crouching, same action but maybe adjusting.

Frame 2: they move the tool, then reach for the knife (since next frame has a knife). Wait, the next frames: in frame 2, the person moves the tool, then in frame 3, they hold a knife and cut the container. Then frame 4: they use the knife on the container, then frame 5: they stop, holding the knife and the container.

Wait, the key actions: crouching, using a tool (drill?) on a white container, then using a knife to cut the container. Then holding the knife and the container.

Appearance: person is wearing a white t-shirt, plaid shorts, black sneakers with white stripes. The container is white, cylindrical. Background has green buckets, a brick wall, a door.

Chronological order:

- The person is crouching on a concrete surface, holding a long tool (likely a drill bit) inserted into a white cylindrical container. They adjust the tool, then switch to using a knife, which they use to cut or open the container. After using the knife, they hold the container and the knife.

Spatial relationships: The person is in front of a brick wall and green buckets. The concrete surface is where they're working.

Camera perspective: It's a static shot, no movement mentioned, so probably a fixed camera angle, top-down? Wait, the video is filmed from a slight angle, but the problem says "camera perspective and movement (e.g., top-down, pan left, slight shake)". The description says "static camera" or "fixed angle".

Now, following the rules:

a) Motion and behavior in chronological order.

b) Appearance of main subjects: person in white t-shirt, plaid shorts, black sneakers; white container.

c) Spatial: person crouching on concrete, with green buckets behind them.

d) Camera: static, fixed angle.

e) Minimal background: green buckets, brick wall.

f) Exclude text, named characters.

Let's put it all together.

First, the person is crouching. Then using a tool on the container. Then using a knife. Then holding the container and knife.

" A person crouches on a concrete surface, holding a long tool inserted into a white cylindrical container, then adjusts the tool before switching to a knife and using it to cut the container. The individual, dressed in a white T-shirt, plaid shorts, and black sneakers, remains in front of a brick wall with green buckets in the background. The camera remains static throughout, capturing the actions from a fixed angle."

Wait, check the exact actions: first, the person is using the tool (drill bit) into the container, then moves the tool (maybe removing it?), then uses the knife to cut. Let's check the frames:

Frame 0: crouching, holding tool in container.

Frame 1: same, but maybe rotating the tool.

Frame 2: person moves the tool away, then picks up a knife.

Frame 3: person uses knife on the container.

Frame 4: person cuts the container with the knife.

Frame 5: stops, holding knife and container.

So the chronological order: crouch, use tool on container, adjust tool, then use knife on container.

So the caption should be: A person crouches on a concrete surface, holding a long tool into a white cylindrical container, then adjusts the tool and switches to a knife, using it to cut the container. The individual, wearing a white T-shirt, plaid shorts, and black sneakers, works in front of a brick wall with green buckets behind. The camera remains static.

Check for rules:

a) Motion in order: crouching, using tool, adjusting, using knife.

b) Appearance: person's clothes, container.

c) Spatial: in front of brick wall and green buckets.

d) Camera: static.

e) Background minimal (green buckets, brick wall are essential? Maybe minimal is okay

A person (discrete solid object) is actively moving: manipulating a tool (shovel) to interact with the ground, adjusting their posture, and handling a white container. The tool and container are solid objects moving due to the person's actions.

The brick wall and green buckets in the background are stationary and show no shifting or environmental fluid motion (e.g., fire, water, smoke, wind). No ambient environmental phenomena are present.


A man in a blue shirt and beige pants stands near cricket wickets on a grassy field, holding a camera. Another man in a striped shirt and white pants approaches with a cricket bat, high-fives the first man, then walks past him to the right. The camera remains stationary with minimal movement.

Two people: one in blue shirt (stationary then slightly moves) and one in striped shirt and white pants (walks toward the wicket, swings a cricket bat, then interacts with the other person). The cricket bat is swung as a discrete object motion due to physical force.

The background (trees, distant structure) is static with no significant fluid or wind-driven motion. The grass is flat and uniform. No fire, water, or smoke observed.


A person wearing a light gray sweatshirt with dark graphic designs holds a silver flute, bringing it to their lips to play; the background features a colorful poster on the wall. The camera maintains a fixed perspective with minimal movement.

A person is moving their fingers on a flute (discrete solid object), indicating explicit physical motion from manual interaction with the instrument.

The background (walls, posters) shows no uniform shifting or fluid/environmental motion (fire, water, smoke, wind); static elements remain consistent across frames.


The video opens with a light blue "HowTo" logo on a beige background, followed by a close-up of a blue and white braided rope tied into a knot. A pair of hands then appears, manipulating a blue and white rope around a wooden post. The hands loop the rope, wrap it around the post, and pull to secure the knot. The camera maintains a top-down perspective focusing on the hands and rope, with minimal background details visible.

Hands manipulate a rope to tie a knot; the rope and hands exhibit deliberate physical movement due to manual manipulation.

Background features a static wooden floor and rod; no shifting backgrounds or fluid/environmental motion (fire, water, smoke, wind) observed.


RAW CAPTION: Got it, let's break this down. The video shows a hockey player on an ice rink. First, the player is skating, then they do a move that creates a spray of ice. Let's check the steps.

First frame: player in motion, hockey stick, grey shirt, dark pants with orange stripes. Then they crouch, maybe a maneuver, and in the next frames, they're skidding, causing ice spray. The camera starts at a low angle, maybe close to the ice, then moves with the action, possibly getting closer as the player skates and sprays ice.

Need to describe chronological order: the player skates forward, then executes a move (maybe a quick turn or stop) leading to ice spray. Mention appearance: grey top, dark pants with orange, ice skates. Spatial: on the rink, background has flags but minimal. Camera perspective: starts low, follows the action, maybe moves with the player's motion.

Wait, the video starts with the player skating, then they lower their body (crouch), then there's a spray of ice. So sequence: player moves forward, crouches, then skates hard, causing ice to spray up. The camera is low, close to the ice, and might be moving forward with the player.

Check rules: focus on motion, chronological. "A hockey player in a grey top and dark pants with orange stripes skates across the ice rink. The player lowers their body, then executes a sharp turn, causing a spray of ice to erupt from their skates. The camera remains low and close to the ice, tracking the player’s movement as the ice spray intensifies."

Wait, need to check if background is minimal. Background has flags but not essential. Camera movement: starts at a low angle, possibly moving forward to follow the player's action.

Let me make sure to follow all rules. Exclude text recognition (like the scoreboard), named characters (no names), stylistic analysis. Just motion, appearance, spatial, camera.

So the caption should be:

A hockey player wearing a grey top and dark pants with orange stripes skates across the ice rink, then crouches and executes a sharp maneuver, causing a burst of ice spray to rise from their skates. The camera maintains a low, close perspective, following the player’s motion as the ice spray intensifies.

Wait, the video shows the player moving, then the spray. Let's check the timestamps:

0.0: player skating, stick in hand.

1.4: player is crouched, moving.

2.5: still crouched, maybe turning?

3.6: ice spray, close-up on skates.

4.7: spray continues, camera angle low.

So sequence: skates, crouches, turns/shifts, causes ice spray. The camera is close to the ice, moving with the action.

So revised caption:

A hockey player in a grey top and dark pants with orange stripes skates forward on the ice rink, lowers their body, and executes a sharp turn, generating a spray of ice particles. The camera remains at a low angle, closely tracking the player’s movement as the ice spray intensifies around their skates.

Check all rules: chronological order (skating, crouching, turning, spray), appearance (grey, dark with orange), spatial (on rink, ice spray), camera (low angle, tracking). Background minimal. No text recognition (scoreboard is there but not mentioned as per rule e, minimal unless essential; the score is part of the background but the rule says minimal so maybe omit? Wait, the rules say "Mention spatial relationships if relevant (e.g., in front of, to the left). Background descriptions minimal unless essential for understanding motion." So if the background isn't essential for motion, don't mention. The flags are there but not needed, so omit.

Yes, the caption should be concise, focus on main subject's motion. So:

A hockey player in a grey top and dark pants with orange stripes skates across the ice rink, crouches, and executes a sharp maneuver that causes a burst of ice spray. The camera maintains a low, close perspective, following the player’s movement as the spray intensifies.

Wait, "sharp maneuver" might be specific, but maybe "turn" is better. Let's see the video: the player is moving, then they crouch, then the skates are moving in a way that kicks up ice. So the action is a quick turn or pivot.

Also, the camera perspective: the initial frames are from a low angle (close to the ice), and as the player skates, the camera follows, so it's tracking.

Let me try to structure:

A hockey player wearing a grey shirt and dark pants with orange stripes skates forward on the ice rink. The

A hockey player (wearing helmet, jersey, and skates) is moving. The player's locomotion (skating and sharp turn) generates ice particle spray as a direct consequence of physical forces applied to the ice surface.

Background elements (walls, goal post, ice rink boards) remain stationary with no uniform shifting. The dominant motion is transient ice particles kicked up by the skater, not continuous fluid/environmental phenomena (fire, water, smoke, wind).


RAW CAPTION: Got it, let's tackle this. First, the video shows a person in a dark room. They're wearing a dark crop top and blue shorts. The main action is the person moving. Let's check the timestamps.

At [0.0], the person is in a pose, arms out. Then [1.0] they start moving forward. By [2.0] they're walking towards the camera. [3.0] they get closer, still moving. [4.0] they're near the center, maybe adjusting position. [5.0] they're closer, arms moving. Need to describe the motion chronologically.

Appearance: female, dark crop top, blue shorts, barefoot. Number: one person.

Spatial relationships: initially near a wooden post (left) and a table with a circular object (right), but as they move, they're moving towards the camera. Background is dark with string lights, but minimal.

Camera: seems stationary, maybe slight shake? The description says "keep background minimal", so focus on movement.

So structure: start with the person moving forward, their appearance, actions over time, camera.

Let me draft:

A person wearing a dark crop top and blue shorts walks barefoot towards the camera in a dimly lit room. Initially positioned near a wooden post and a table with a circular object, they move forward with arms gesturing, adjusting their stance as they approach. The camera remains stationary with slight motion.

Wait, check rules: chronological paragraph. Start from first frame.

Frame 0: person in a pose, arms extended. Then they start walking towards camera, steps, arms moving. So "A person in a dark crop top and blue shorts, barefoot, begins walking toward the camera in a dimly lit room. Starting from a position near a wooden post on the left and a table with a circular object on the right, they take steps forward, extending their arms and adjusting their stance as they approach closer to the camera. The camera remains stationary with slight shake."

Wait, background is dark, minimal description. So maybe skip "dimly lit room" but need to mention if essential. The room has string lights but maybe not essential. The main motion is the person moving.

Check rule e: minimal background unless essential. The wooden post and table might be spatial, so mention briefly.

Let's structure step by step:

1. First frame: person is standing with arms out (maybe dancing or moving).
2. Then they walk towards camera, step by step.
3. Their posture changes, arms moving.

So: A person wearing a dark crop top and blue shorts, barefoot, moves through a dark space. Beginning near a wooden post and a table with a circular object, they take steps forward, swinging their arms as they approach the camera. The camera remains fixed.

Wait, the video has 5 frames. Let's see:

[0.0] person with arms out, maybe mid-movement.

[1.0] walking towards camera.

[2.0] closer, moving forward.

[3.0] even closer, arms moving.

[4.0] near center, arms gesturing.

[5.0] closer, arms moving.

So the main motion is walking towards camera, arms moving. Appearance: crop top (dark), shorts (blue), barefoot. Number: 1.

Spatial: initially near wooden post (left) and table (right), then moving towards camera (center).

Camera: stationary, maybe slight shake. The output says "conclude with camera perspective".

So:

A person in a dark crop top and blue shorts, barefoot, walks toward the camera in a dimly lit room. Starting near a wooden post on the left and a table with a circular object on the right, they take steps forward with arms gesturing, adjusting their posture as they approach closer to the center of the frame. The camera remains stationary with slight movement.

Check rules:

a) Motion chronological: yes, starts near post/table, moves forward.

b) Appearance: described (dark crop top, blue shorts, barefoot).

c) Spatial: near wooden post (left) and table (right), then towards center.

d) Camera: stationary, slight movement.

e) Background minimal: dimly lit room, but maybe needed for context.

f) Excluded text, etc.

g) Internal thinking, no output.

Now, make concise. Maybe:

A barefoot person wearing a dark crop top and blue shorts walks toward the camera in a dark space. Initially positioned near a wooden post on the left and a table with a circular object on the right, they take steps forward while gesturing with their arms, moving closer to the center of the frame. The camera remains stationary with minor shake.

Yes, that's concise. Let's check length.

Alternative: "A person in a dark crop top and blue shorts walks

A person (wearing black top and blue shorts) is dancing, moving their arms, legs, and torso.

The background (wooden wall, table, string lights) is static. No fire, water, smoke, or wind present.


A person wearing a gray tank top, black leggings, and red sneakers begins in a low pushup stance, then pushes up into a plank position, followed by rapidly drawing knees toward their chest in a mountain climber motion. The exercise occurs in a gym setting with blue walls and equipment visible in the background, filmed from a static side angle.

A person is performing dynamic exercises (push-ups, lunges) involving controlled movement of limbs and torso.

The background consists of static gym equipment (mats, bars, blue walls) with no shifting or fluid motion (e.g., water, smoke, fire). No ambient environmental elements are present.


A pair of adult hands holds a gold circular smartwatch, manipulating its position and interacting with the screen, which transitions between various display interfaces. The camera maintains a static close-up perspective focused on the hands and device.

Hands are manipulating the smartwatch (rotation, slight movements), and the smartwatch screen displays interface changes; both are solid objects with explicit physical interactions (holding and adjusting).

The background (dark surface and clothing) shows no significant shifting or fluid motion; no fire, water, smoke, or wind is present.


A man in a black shirt and bow tie holds a small blue bottle with his right hand while using a tool in his left hand to unscrew the cap. The camera shifts to a close-up of his hands as he rotates the tool to open the bottle, with the bottle positioned in front of a clear glass container. Background elements include shelves and windows, but remain out of focus. The camera movement transitions from a medium shot to a tight close-up on the hands and bottle.

Discrete objects: the person's hands and the blue bottle. Motion: hands tilting the bottle to pour liquid.

The background is static (bar setting) with no shifting. No fire, water, smoke, or wind as dominant motion.


A woman with blonde hair wearing a gray shirt holds a phone as a person in a blue shirt hands her a brown blanket; she accepts it, adjusts the blanket, and holds it while surrounded by a crowd. The camera, handheld with slight shake, focuses on the interaction between the two individuals.

Brief description of background and ambient


A male athlete in dark athletic wear leaps from a red runway into a sandpit, landing and rising before walking back along the runway toward the starting area. Spectators stand on the grassy field to the left, observing the motion. The camera remains stationary throughout.

A single athlete (discrete solid object) moves through a sequence of actions: running towards the sand pit, jumping, and landing. The motion is driven by physical forces (muscular exertion, gravity) during locomotion and impact.

Static background elements (trees, spectators, track) show minimal movement; no significant fluid motion (fire, water, smoke) or wind-driven environmental effects observed.


A person in a light blue shirt, dark pants, and hat steers a green three-wheeled vehicle with a white and yellow sail across a sandy beach. The vehicle moves forward, revealing the surrounding sandy terrain with scattered rocks and distant dunes under a clear sky. The camera pulls back to a wider angle, following the vehicle’s motion from a side perspective while maintaining a steady shot.

A person operating a green cart with a sail moves forward across the sandy terrain, steering and controlling the cart's direction via the sail and handle.

The sandy beach and distant vegetation remain static with no significant uniform shifting. No fluid/environmental motion (fire, water, wind) dominates the scene; wind is present but not the primary motion driver.


Multiple individuals in black wetsuits with white helmets move underwater in an aquarium, interacting closely while bubbles rise from their helmets. One person gestures toward a passing shark, others adjust positions near rocky terrain as fish swim in the background. The camera follows their motion through the water, maintaining a steady view of their interactions.

Discrete solid objects include performers in wetsuits (moving arms/legs, interacting with marine life) and a marine animal (e.g., seal/sea lion) exhibiting controlled motion in response to the performers.

The background features a large aquarium environment with water and marine structures; however, the water is not the dominant motion source as it appears static relative to the subjects. The aquarium walls do not shift uniformly, indicating no significant ambient environmental motion.


RAW CAPTION: Got it, let's see. The video shows hands doing something with a needle and thread. First, a hand holds a piece of fabric or maybe a small object, and the other hand uses scissors. Wait, the first frame has hands: left hand holding something, right hand with scissors cutting thread. Let's check the steps.

In the video, the left hand is holding a small, light brown object (maybe fabric or hair? But the task says don't describe appearance beyond necessary). The right hand uses scissors to cut a thread. The motion is: the left hand holds the object, the right hand moves scissors to cut the thread. Then the scissors are positioned to cut, and the thread is being trimmed.

Chronological order: The left hand holds the object (maybe a small item, like a fabric sample), the right hand brings scissors to cut the thread attached to the object. The scissors close around the thread, and the thread is cut. Then the scissors are pulled back. So the main subjects are two hands, one holding the object (light brown, small), the other holding scissors (metal, sharp). Spatial relationship: left hand is in front, right hand is to the right, using scissors.

Camera perspective: close-up, static, looking directly at the hands. Background is a solid blue wall and a wooden surface, but minimal description as per rules.

So the caption should be: Two hands are shown in close-up; the left hand holds a small light brown object, while the right hand maneuvers metal scissors to cut a thin thread attached to the object, moving the scissors toward and away from the thread. The camera maintains a static top-down view against a plain blue background with a wooden surface below.

Wait, check rules: focus on motion and behavior in chronological order. So step by step: left hand holds object, right hand brings scissors to cut thread. Then scissors close around the thread, cut, then move away.

Let's structure it:

"Two hands are visible in a close-up shot. The left hand holds a small light brown object, while the right hand uses metal scissors to cut a thin thread attached to the object. The scissors approach the thread, close around it, and then move away as the thread is severed. The camera remains static, focused on the hands against a plain blue background with a wooden surface."

But need to be concise. Also, the first part: "A hand holds a small, light brown object (likely fabric or thread), while another hand uses scissors to cut the thread. The scissors close around the thread, severing it, and are then withdrawn. The camera maintains a static close-up view against a plain blue backdrop with a wooden surface visible at the bottom."

Wait, but the video shows the hand holding the object (maybe a small piece of material), scissors cutting the thread. The key motions: left hand holds, right hand uses scissors to cut. So chronological: the left hand grips the object, the right hand positions scissors near the thread, then cuts, then pulls back.

Let me check the frames: in the first frame, the left hand is holding the object, right hand scissors near the thread. Then scissors cut. So the motion is from left to right, but the action is the cutting.

So the caption:

"A pair of hands is shown in close-up; the left hand holds a small light brown object, while the right hand manipulates metal scissors to cut a thin thread attached to the object. The scissors close around the thread, severing it, and are then moved away. The camera remains static, capturing the action from a top-down perspective against a plain blue background with a wooden surface visible."

Wait, but the rules say "concise, chronological paragraph". Let's make it shorter.

"Two hands are visible: the left holds a small light brown object, the right uses scissors to cut a thread attached to it. The scissors close around the thread, sever it, and retract. The camera stays static, focusing on the hands against a blue backdrop with a wooden surface below."

But check if "light brown" is necessary. The rules say "briefly describe appearance and number (color, size, orientation)". So "small light brown object" is okay.

Also, spatial relationships: the left hand is on the left, right hand on the right, scissors moving towards and away from the thread.

So final caption: "Two hands appear in a close-up; the left hand holds a small light brown object, while the right hand uses metal scissors to cut a thin thread attached to the object. The scissors close around the thread, severing it, then retract. The camera maintains a static top-down view against a plain blue background with a wooden surface visible at the bottom."

Wait, but the video might be top-down or not? The description says "top-down" but maybe it's just close-up. The user says "camera perspective and movement (

Two hands and a metal wire are the discrete solid objects; the hands manipulate the wire using tweezers, causing the wire to move due to applied force.

RAW CAPTION: Got it, let's tackle this. The video shows a man in a gym doing a weightlifting exercise. First, he's holding a barbell with yellow weights. He starts in a squat position, then lifts it up to his shoulders. Then he stands up, holds it, and lowers it back down. The gym has various equipment like machines and weights in the background. The main subject is the man, wearing a black tank top, black shorts with a green stripe, red shoes. The camera is static, so no movement. Need to describe the sequence chronologically.

Check the rules: chronological order of motion. So first, he's in a squat with barbell at chest? Wait, no, the frames: [0.0] he's lifting from the ground to shoulders? Wait, the first frame: he's holding the barbell, then [1.4] he's in a squat position (so the bar is at waist level, then he squats down), then [2.5] he's standing with bar at shoulders, then [3.6] he lowers the bar, then [4.7] he's in a squat again? Wait, the video is a sequence. Let's parse the frames:

Frame 0: He's lifting the barbell from the ground (knees bent, bar at waist level? Wait, no, in weightlifting, usually a clean and jerk or snatch. Wait, he starts with the bar at his shoulders? Wait, no, the first frame shows him with the bar at his shoulders, then he squats down (so he's doing a squat with the bar on shoulders). Wait, the description: [0.0] he's holding the bar, then [1.4] he's in a squat position (so he lowered the bar to his knees?), wait, no. Wait, the action is: he starts by lifting the barbell from the ground up to his shoulders (so the first movement is lifting), then he squats down (so the bar is at shoulders, he lowers into squat), then he stands up (bar remains at shoulders), then he drops the bar back down to his chest? Wait, the frames: 0.0: bar at shoulders, he's squatting. Wait, no, let's look at the sequence.

Wait, the user provided frames: [0.0] the man is holding a barbell with yellow weights at his shoulders, knees bent (squat position). Then [1.4] he's lifting the bar up (so standing up), [2.5] he's standing with bar at shoulders, [3.6] he lowers the bar to his chest (maybe), [4.7] he's again in a squat position. Wait, no. Wait, maybe it's a squat clean: he starts with the bar on the floor, lifts it to shoulders, then squats down, then stands up. But in the video, the first frame shows him with the bar at his shoulders, knees bent (squat), then he stands up (bar stays on shoulders), then lowers the bar to his chest, then squats again. Wait, no. Let me recheck.

Wait, the video is a sequence of frames. The caption needs to describe the motion chronologically. So the first frame (0.0) shows the man holding a barbell with yellow weights at his shoulders, knees bent (squat position). Then in 1.4, he's standing up (bar still at shoulders). Then 2.5: he's standing with bar at shoulders. Then 3.6: he's lowering the bar down to his chest (maybe a dip), then 4.7: he's in a squat position again. Wait, no. Wait, maybe it's a front squat or clean. Let's think of the motion.

Wait, the main action is: the man lifts the barbell from the ground to his shoulders (first movement), then lowers it to his chest (squat down), then stands up, then maybe does a jerk. Wait, no, the frames: 0.0: he's lifting, 1.4: he's in a squat (so after lifting, he's lowering), 2.5: standing, 3.6: lowering again, 4.7: squatting again. Hmm, maybe it's a front squat or a clean. Wait, perhaps it's a squat: he starts with the bar on his shoulders, squats down (1.4), stands up (2.5), then squats again (3.6, 4.7). Wait, the description in the frames: the barbell has yellow weights. The man is wearing black shirt, black shorts with green stripe, red shoes.

So the sequence: The man, dressed in a black sleeveless top
