RAW CAPTION: Got it, let's tackle this video captioning task. First, I need to focus on the main subject. The video shows a man in a dark sleeveless shirt. He's seated, with his arms spread wide. There's a rope tied around his neck, which is a key detail. Let's go chronologically.

Looking at the frames: at the start, he's holding the rope with both hands, arms out. Then, he moves his hands slightly. In the later frames, his hands are near his chest. Wait, the timestamps are 0 to 5 seconds. So the sequence is: he starts with arms extended, holding the rope, then his hands move downward towards his chest.

Appearance: Man, dark sleeveless shirt, has a beard, tattoos on arms. Background has a window with blinds and a valance curtain. But rule e says minimal background unless essential. Since the window is behind him, maybe mention it briefly.

Spatial relationships: The rope is horizontal, across his neck. He's in front of the window. Camera is static? The video description says "slight shake" maybe? Wait, the user's example says "conclude with camera perspective and movement". The video is a fixed shot, probably no movement, but the user's rules say "slight shake" might not be there. Wait, the problem says "DO NOT include any reasoning", so just follow the output format.

Wait, the rules: a) motion and behavior in chronological order. So step by step:

- Man seated, rope around neck, arms extended outward. Moves hands slightly downward towards chest. Background: window with blinds and valance curtain.

Camera perspective: The camera is positioned to capture him from the front, looking straight at him, no significant movement (since it's a fixed shot).

Now, check rules: b) describe appearance and number. Main subject is one man, dark sleeveless shirt, beard, tattoos on arms.

c) spatial relationships: in front of window with blinds.

d) camera: front view, static.

e) background minimal: mention window briefly.

f) exclude text, names, stylistic.

So putting it all together.

First, the man is seated, rope around his neck, arms spread. Then he moves his hands down. Background: window with blinds and valance. Camera static.

Let me structure it:

"A man wearing a dark sleeveless shirt with a beard and arm tattoos sits in front of a window with blinds and a valance curtain. A rope is tied around his neck, held by his extended arms. He slowly moves his hands downward toward his chest. The camera remains static, positioned directly in front of him."

Check if all rules are met.

a) Motion: starts with arms extended, hands moving down.

b) Appearance: dark sleeveless, beard, tattoos.

c) Spatial: in front of window.

d) Camera: static, front.

e) Background minimal: window mentioned, but valance is part of background.

f) No text, names.

Seems okay. Let's see if it's concise. Maybe shorten:

"A man in a dark sleeveless shirt, with a beard and arm tattoos, sits facing the camera. A rope is tied around his neck, held by his extended arms. He moves his hands downward toward his chest. The background includes a window with blinds and a valance curtain. The camera is static."

Wait, "sits facing the camera" is good. The background is part of the setting. Let me check the exact sequence of motion.

In the frames: first frame, arms extended holding rope; then frame 2, same; frame 3, arms still extended but maybe hands moving; frame 4, hands are near chest; frame 5, hands lower. So he's moving his hands from outstretched to downward.

So the motion is "moves hands downward toward chest".

Now, the caption should be chronological: starts with arms extended, then hands move down.

So combining:

"A man in a dark sleeveless shirt with a beard and arm tattoos sits in front of a window with blinds and a valance curtain. A rope is tied around his neck, held by his outstretched arms. He slowly lowers his hands toward his chest. The camera remains static, capturing the scene from a frontal perspective."

Check for brevity. Maybe:

"A man wearing a dark sleeveless shirt, with a beard and arm tattoos, sits facing a window with blinds and a valance. A rope is around his neck, held by his extended arms; he gradually lowers his hands toward his chest. The camera is static."

Yes, that's concise.

Wait, rule d says "conclude with camera perspective and movement". So last part: "The camera is static."

Including that.

Let me check the output format. Must be within <caption_output> tags.

So final caption:

<caption_output

The man (solid object) exhibits discrete arm and head movements due to muscular locomotion, clearly trackable as a bounding box with minimal overlap with background.

No shifting background elements observed (window blinds and curtain remain stationary). No fluid, gaseous, or wind-driven motion (e.g., no fire, water, or smoke visible).


A person in a black shirt, black pants, and white shoes stands on a stage with dim lighting. They fall backward, rolling across the wooden floor while moving toward the camera, eventually lying on their back with arms raised. The camera follows their motion, shifting angles to capture the roll and final position.

A person in athletic wear moves across the floor, sliding and repositioning themselves—indicating discrete, solid object motion due to physical forces.

Background elements (court lines, walls) remain stationary; no fire, water, smoke, or wind motion observed.


RAW CAPTION: Got it, let's see. The video starts with a person on a skateboard in the middle of a street. They're moving forward, right? Let's check the frames. The first frame shows the person standing still maybe, then they start moving. Wait, no, the first frame is [0.0] and they're in the middle of the street. Then over time, they're moving forward. Let's note the motion: the person is on a skateboard, moving from the left to the right of the frame? Wait, no, the street is paved, sidewalk in front. Wait, the person is on the street, which is a road. So the person is riding a skateboard across the street, moving towards the camera or away?

Wait, looking at the frames: the first frame (0.0) has the person in the middle of the street. Then in frame 1, they're slightly further towards the right? Wait, no, maybe the person is moving forward. Let's check the sequence. The person is on a skateboard, starts in the middle of the street, then moves forward, maybe turning or adjusting. Wait, the description says "chronological paragraph". So:

Start: A person on a skateboard is positioned in the middle of a residential street. They begin moving forward, maintaining balance. As the video progresses, the person continues riding the skateboard across the street, making minor adjustments to their stance. The scene concludes with the person still moving forward, gradually exiting the frame.

Wait, need to check the appearance: the person's color, size. The video shows a person, probably wearing dark top and light pants, but since it's a brief video, maybe just say "a person wearing dark upper clothing and light pants". But the rules say briefly describe appearance. Also, number: only one person.

Spatial relationships: the person is on the street, with a sidewalk in the foreground. Background has trees and a house, but minimal.

Camera perspective: it's a static shot, no movement. The video is from a fixed camera position, looking across the street. So camera is stationary.

Wait, the rules: "Conclude with camera perspective and movement". So camera is stationary, top-down? No, it's eye-level, since it's a street scene. The camera is static, no movement.

So let's structure:

A person on a skateboard rides across a residential street, starting from the center and moving forward. The individual, wearing dark clothing, maintains balance while adjusting their stance slightly as they travel. The scene remains static, with the camera fixed in position.

Wait, need to be concise. Let's check the frames:

0.0: person on skateboard in the middle of the street.

1.4: same person, slightly further forward.

2.5: same, moving.

3.6: maybe turning or moving towards the sidewalk?

4.7: still moving forward.

Wait, the last frame (4.7) shows the person still on the street. So the motion is continuous. Let's describe the chronological order: starts in the street, moves forward, continues moving, exits? No, the video ends with them still moving.

So the caption:

A person on a skateboard begins riding across a residential street, moving forward from the center of the frame. The individual, wearing dark top and light pants, maintains balance while making minor adjustments to their stance. The camera remains stationary throughout, capturing the motion from a fixed eye-level perspective.

Wait, but need to keep it concise. Let's see:

A person on a skateboard moves forward across a residential street, maintaining balance with slight adjustments to their stance. The individual, dressed in dark clothing and light pants, rides from the center toward the right side of the frame. The camera remains static, positioned at eye level.

Wait, but the background: minimal background, so just mention residential street, sidewalk in foreground.

Wait, the rules say "exclude text recognition, named characters", so just the main subject.

Let me check the rules again:

a) Motion and behavior in chronological order.

b) Briefly describe appearance and number (color, size, orientation).

c) Spatial relationships if relevant.

d) Conclude with camera perspective and movement.

e) Background minimal.

So:

In the video, a person on a skateboard rides forward across a residential street, starting near the center and moving toward the right side of the frame. The individual, wearing dark clothing and light pants, maintains balance with minor adjustments to their posture. The camera remains stationary, capturing the motion from a fixed eye-level perspective.

Wait, but the video might be moving towards the camera? Let's check the frames. The first frame shows the person in the middle, then as time passes, they move closer? Wait, no, the street is the same. Maybe the person is moving from left to right? Wait, the sidewalk is in the foreground,

A single person is seen running along the road, exhibiting locomotion consistent with discrete object physics (solid, distinct movement due to physical force).

The background elements (house, trees, road) remain static across frames with no fluid motion (fire, water, smoke) or wind-driven swaying observed. No environmental motion dominates the scene.


A person’s hands manipulate a colorful fishing lure with orange and black striped tail fibers, green and brown wispy feathers, and metallic threads, adjusting and repositioning the feathers in front of the lure. The camera remains in a steady close-up, focusing on the detailed hand movements and the lure’s vibrant appearance against a blurred indoor background.

The person's hands are manipulating a fly fishing lure. The hands move the lure, adjusting its position and feathers.

Static background (indoor setting) with no shifting. No fire, water, smoke, or wind visible.


A person wearing a maroon shirt slices a red tomato into thin pieces on a white cutting board using a knife, then transfers the slices into a clear plastic container filled with chopped green and red vegetables positioned to the right of the board. A whole cucumber rests on the black countertop below. The scene is captured from a static top-down perspective with minimal background details visible.

Person's hands cutting a tomato with a knife on a cutting board; discrete solid objects (hands, knife, tomato) moving due to manual action.

Background (tiled wall, countertop) is static with no shifting; no fluid motion (fire, water, smoke) or wind observed.


A person wearing a dark shirt and a bracelet on their left wrist plays a black piano, their hands moving rhythmically over the keys in the left portion of the frame. The camera remains static, focusing closely on the hands and piano keys as they press down on the black and white keys.

A person's hands (discrete solid objects) move to press piano keys, exhibiting clear physical motion from explicit action (playing piano).

Background elements (door, curtains, walls) show no uniform shifting or fluid motion (e.g., no fire, water, or wind). Static background confirms lack of ambient environmental dominance.


A person is moving their hand (holding a blue object) rhythmically while playing an instrument; the motion is due to explicit physical forces (muscle movement).

Background (wall and chair) is stable with no uniform shifting. No fire, water, smoke, or wind observed.


A worker wearing an orange helmet and dark shirt uses a chainsaw to cut a large split log, causing the log to split further as the chainsaw moves. The worker steps back, revealing another person in a red shirt and helmet working near additional logs in the background. The camera pans from a close-up of the log’s split sections to show the worker and surrounding area with trees and equipment.

A person (lumberjack) is operating a chainsaw, causing the chainsaw to move rapidly as it cuts through a log. The lumberjack also moves slightly to adjust position.

The background (trees, logs, barrel) is stable with no uniform shifting. There are no dominant fluid motions (fire, water, smoke) or significant wind effects visible.


A hand with a blue wristband holds a red and yellow apple, splits it into two halves, then picks up a yellow lemon half to apply lemon juice onto one apple half. The scene occurs on a dark countertop with a second lemon half visible. The camera maintains a top-down perspective with minimal movement.

A hand manipulates a red apple (cutting it into halves), then shifts to interact with lemons. The apple and lemons are solid, distinct objects moving due to manual handling.

The background consists of a static dark countertop with a lemon, apple, and spoon; no fluid motion, fire, or wind is present. Background elements remain fixed relative to the scene.


A man wearing a black t-shirt with a white graphic and gray shorts stands in a room with light blue walls and white doors. He initially looks upward at a colorful ball near the ceiling, then moves the object in his hand downward, steps forward toward the camera, and extends his arm, bringing his hand close to the camera lens, which fills the frame. The background features two white doors with visible hinges and a wall light switch. The camera remains static until the final frame where the man’s hand obscures the view.

The man is the primary discrete object moving, walking toward the camera and making gestures. Additionally, a ball is thrown and caught (transient motion).

The background (light blue walls and white doors) remains static throughout the video. No environmental elements such as fire, water, smoke, or wind are present.


A person's hands, wearing a dark watch and ring, manipulate a bright green strip of material positioned on a yellow and gray Ryobi tool. The hands adjust the strip horizontally, then move it forward through the tool, causing the strip to slide off the surface. The strip is removed from the tool's workspace. A black and yellow drill is visible in the background on a wooden surface. The camera maintains a top-down perspective throughout, with no noticeable movement.

A person's hands manipulate a green strip through a Ryobi-powered tool, causing the strip to move linearly; the tool and hands are discrete solid objects interacting physically.

No shifting background elements or fluid/environmental motion (fire, water, wind) observed; background objects (e.g., wooden block, camera on tripod) remain stationary.


A person wearing a white tank top, dark shorts, and black shoes sits on a gym floor, holding a large dark weight ball. They lift the ball upward toward their chest while sitting up, then lower it back to their lap, repeating the motion. The gym background includes vertical bars, weights, and ropes. The camera remains stationary, capturing the person’s movements from a frontal perspective with minimal spatial shifts.

The person performs sit-ups, moving the body up and down while lifting a medicine ball. The medicine ball is moved by the person's arms.

The background (walls, gym equipment) is static with no uniform shifting. No fluid/environmental motion (fire, water, smoke, wind) is observed.


A dark-skinned hand holds a small, multicolored object featuring orange, green, and white patterns, maintaining a steady grip with minimal movement. The object remains centered against a dark background with a faint light source visible to the right. The camera exhibits a slight shake, capturing the scene from a close-up perspective focused on the hand and object.

A person holds a colorful object; subtle movements of the object and person's hand are visible, indicating manual manipulation.

Background elements (door, wall) are static; no fluid motion (fire, water, smoke, wind) observed.


RAW CAPTION: Got it, let's break this down. The video starts with a toddler at an outdoor table. The kid is wearing a blue striped shirt, sitting at a glass table with a plate of food (like fruits and maybe some snacks) and a sippy cup with an orange top. The background is a wooden deck railing and part of a house.

Then, the toddler moves their hands, maybe waving or reaching. Next, a hand comes into the frame holding a black can (looks like a Monster Energy drink), which is placed on the table near the sippy cup. The toddler's actions: in the first frame, maybe eating or playing with food, then moving, then the hand with the can appears.

Need to describe chronologically. First, the toddler at the table, interacting with the sippy cup and food. Then, the toddler's hand movement. Then, an adult's hand brings the can into the frame and places it on the table.

Check the rules: focus on motion and behavior. Mention appearance (blue striped shirt, sippy cup orange top, black can), spatial relationships (table in front, deck railing behind). Conclude with camera perspective—probably a fixed shot since it's a sequence, but maybe slight shake? Wait, the video might have some movement, but the main thing is the sequence of actions.

Background is minimal: wooden deck, house. So describe the main subjects' actions step by step.

Start: Toddler in blue striped shirt sits at glass table, hands near sippy cup (orange top) and food plate. Moves hands, then an adult’s hand enters from the right, holding a black can, places it on the table near the sippy cup.

Make sure it's concise, chronological. Avoid text, named characters.

Let me structure it:

A toddler in a blue striped shirt sits at a glass outdoor table, interacting with a sippy cup (orange top) and a plate of food. The child moves their hands, then an adult’s hand enters the frame from the right, placing a black can on the table next to the sippy cup.

Check for rules: motion and behavior in order, appearance (blue shirt, orange top sippy, black can), spatial (table, deck railings), background minimal. Camera perspective—probably a handheld shot with slight movement, but the problem says conclude with camera perspective. Wait, the example might not have that, but the rules say "conclude with camera perspective and movement". So maybe "The camera maintains a slight shake as it captures the sequence."

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

In the video, it's likely a handheld shot, so "slight shake". Let's see.

Let me draft:

A toddler in a blue striped shirt sits at a glass table on a wooden deck, interacting with a sippy cup (orange top) and a plate of food. The child moves their hands, then an adult's hand enters from the right, placing a black can next to the sippy cup. The camera remains static with a slight shake during the sequence.

Wait, is the camera static? The description might not specify, but the problem says to include camera perspective. The original video might have some movement, but the task says to describe as per the video. Since the user provided the video frames, the camera might be handheld. But let's check the rules again: "Conclude with the camera perspective and movement".

Looking at the frames, the camera is likely capturing from a slightly angled view, maybe handheld with a slight shake.

Let's finalize:

A toddler in a blue striped shirt sits at a glass outdoor table with a sippy cup (orange top) and a plate of food. The child moves their hands, then an adult’s hand enters from the right, placing a black can on the table near the sippy cup. The camera maintains a slight shake throughout the sequence.

Wait, but the background: minimal, so just mention the deck and house. But rules say "background descriptions minimal unless essential for understanding motion". Since the motion is at the table, maybe the deck railing is part of the background but not essential. So maybe not include the background beyond what's necessary.

Wait, the first frame shows a wooden deck railing behind the table. So perhaps "sits at a glass table on a wooden deck" is okay.

Let me check again:

- Main subjects: toddler, adult's hand, objects (sippy cup, plate, food, can).

Chronological order:

1. Toddler sits at table, interacts with sippy cup and food.

2. Toddler moves hands (like waving or reaching).

3. Adult's hand enters from right, places black can next to sippy cup.

Appearance: toddler in blue striped shirt; sippy cup orange top; black can.

Spatial: table in front

Child (blue shirt) moves hands to interact with bottle and plate; adult hand (holding dark soda can) enters frame to interact with bottle.

Background elements (wooden railing, building structure) show no uniform shifting; no fire, water, smoke, or wind detected.


Two hands manipulate a set of playing cards; the left hand holds a 10 of Hearts card with red hearts, while the right hand flips through adjacent cards, revealing their backs and faces. The cards are moved in a sequence, with the right hand’s motion causing the cards to shift. The camera maintains a top-down perspective throughout.

Hands are manipulating playing cards (shuffling, showing, turning), which are solid objects moving due to explicit physical forces (hands).

No shifting background or fluid motion. Background (table surface) is static.


A woman stands in front of a blue-toned map of France, initially with hands clasped, then gestures with both hands while shifting her body orientation slightly to her left. The camera remains stationary, maintaining a medium shot.

The woman is the only discrete object moving, with gestures and body movement driven by her physical actions.

The background (map of France) is static with no fluid/environmental motion (fire, water, smoke, wind). No shifting background elements observed.


Hands hold a pink lace fabric with intricate patterns, then place a shiny red object with a detailed design onto the fabric. The hands adjust the red object's position on the lace, lift the lace to reveal the object underneath, and reposition the fabric. The camera maintains a static top-down view throughout the sequence against a plain white background.

Hands manipulate a red apple and a patterned fabric, with movements involving grasping, rotating, and positioning the objects.

The background consists of a static white surface and a patterned fabric; no shifting background elements or fluid/environmental motion (fire, water, wind) are present.


A person wearing a dark beanie and gray hoodie walks away from the camera toward a doorway. A second person, dressed in a plaid shirt and dark blue t-shirt, steps out from the doorway, gestures with their hands while moving forward, and exits the frame to the right. The camera remains static throughout, capturing the subjects' movements in a room with minimal background details.

Two people: one initially outside the door (walking in) and one inside (reacting and gesturing). Their motion is due to locomotion and hand gestures.

The background (walls, door) remains static; no fluid/environmental motion (fire, water, wind) observed. The door opening is a mechanical action without environmental fluid motion.


Two children interact in a leaf-covered yard; one, wearing a hat, gray shirt, and blue jeans, is initially seated on a black scooter with red handlebars, while the other, in a striped shirt and blue jeans, stands nearby holding a small object. The first child adjusts the scooter, stands, and pushes it forward as the second child moves to their left, briefly kneeling beside the scooter. The background includes scattered leaves, a red tricycle, and a white building. The camera follows the action with slight shake, maintaining a ground-level perspective.

Two individuals: one riding a scooter (motion from standing to propulsion), another kneeling and assisting. Discrete movements of people and scooter due to locomotion.

Background elements (wall, ground, leaves) show no uniform shifting. No fire, water, or wind-driven motion observed.


A small child in a red hooded jacket swings back and forth on a swing, moving from left to right and then back, with trees and a house visible in the background. The camera follows the child’s motion, slightly shaking as it captures the swinging movement.

The child on the swing is the primary discrete solid object, exhibiting back-and-forth motion due to swinging forces.

Background elements (trees, house, ground) are static; no fluid motion (fire, water, smoke, wind) detected.


A person wearing a black sleeveless top and shorts stands on a concrete throwing circle, initiating a rotational motion with arms extended. They spin clockwise, transferring momentum, then release a discus forward through a netted enclosure. The camera remains stationary at a fixed side angle, capturing the athlete’s full motion against a grassy field backdrop with minimal background detail.

A single person in athletic attire is executing a shot put throw, with visible rotation, arm extension, and follow-through motion. The shot put itself is also in motion during the throw.

The background features stationary elements like a grassy field, trees, and distant structures with no significant shifting or fluid motion (e.g., no fire, water, or prominent wind effects).


RAW CAPTION: Got it, let's tackle this captioning task. First, I need to watch the video. The video shows a person with long blonde hair and glasses, wearing a dark jacket. They're braiding their hair. Let's check the sequence.

The person starts by holding a section of hair, then continues braiding. The background has a room with a pink and white checkered curtain, a bed with pillows, and a wall with a picture. But rule f says to exclude background unless essential. Wait, rule e says minimal background unless essential. So maybe just mention the room is visible but not details.

Chronic order: The person is braiding their hair. Their hands move to braid, so motion is hands working on hair. Appearance: long blonde hair, glasses, dark jacket. Spatial: in front of the camera, maybe with curtain behind. Camera: fixed, since no movement mentioned. The video ends with them still braiding. Let's structure.

Focus on motion: person braids hair, hands moving to form braid. Appearance: long blonde hair, glasses, dark jacket. Background minimal, just a room with curtain. Camera is static.

Check rules: chronological order, motion first. So "A person with long blonde hair, glasses, and a dark jacket braids their hair, moving their hands to form a braid. The scene is set in a room with a pink and white checkered curtain in the background; the camera remains stationary throughout."

Wait, need to check if background is essential. The curtain is part of the background, but the main action is the person braiding. Since it's a room, maybe it's essential for setting? Rule e says minimal. So perhaps just "in a room" without details. Wait, the first frame shows a curtain, so maybe mention it's in front of a curtain? But the person is in the center. Let's see.

Wait, the person is in front of the curtain, but the main subject is the braiding. Let's keep it concise. The person is braiding their hair, hands moving. The camera is fixed, no movement.

So structure: [Subject] [action], [motion description]. [Appearance]. [Background minimal]. [Camera].

Let me draft:

A person with long blonde hair, wearing glasses and a dark jacket, braids their hair while holding sections of hair with their hands. The individual stands in a room with a visible pink and white checkered curtain; the camera remains stationary throughout the sequence.

Wait, check if "holding sections" is chronological. First, they grab hair, then braid. So "begins braiding, using hands to manipulate hair strands."

Wait, the video shows them starting to braid, so the motion is hands moving to braid. Let's make it concise.

"A person with long blonde hair and glasses, wearing a dark jacket, braids their hair by moving their hands to interweave strands. The scene occurs in a room with a pink and white checkered curtain in the background, with the camera remaining static."

Is that good? Check rules:

a) Motion: braiding hair, hands moving to braid. Chronological: starts braiding, continues.

b) Appearance: long blonde hair, glasses, dark jacket. Correct.

c) Spatial: in a room with curtain (background), but spatial relationship: the person is in front of the curtain? Maybe not necessary. The rule says mention if relevant. So maybe just "in a room" but since the curtain is part of the background, maybe minimal description.

d) Camera: stationary. Correct.

e) Background minimal: "room with pink and white checkered curtain" is minimal, as it's part of the setting but not essential for motion.

f) Exclude text: no text here.

g) Internal thinking done.

Wait, the video starts with the person holding hair, then braiding. So first action: holding hair, then braiding. But in caption, concise. So "braids hair, moving hands to form a braid."

Let me revise:

A person with long blonde hair, glasses, and a dark jacket braids their hair using their hands to weave strands together. The individual is positioned in a room with a visible pink and white checkered curtain, and the camera remains fixed throughout the sequence.

That's concise. Checks all rules. Let's confirm:

- Motion: braiding hair, hands weaving strands. Chronological: starts braiding, hands move.

- Appearance: long blonde hair, glasses, dark jacket.

- Background: room with curtain, minimal.

- Camera: fixed.

Yes. I think that's good.
</think>

<caption_output>A person with long blonde hair, glasses, and a dark jacket braids their hair by moving their hands to interweave strands. The individual stands in a room with a pink and white checkered curtain visible in the background

A person with long hair is actively braiding their hair; hands and fingers move to manipulate the hair strands in discrete, solid-object motions driven by physical manipulation.

Static background elements (wall, curtain, framed picture) remain consistently positioned with no uniform shifting or environmental motion (fire, water, smoke, wind) observed. No fluid or gaseous phenomena present.


A girl in a blue swimsuit raises her arms in the pool, then lowers them to hold an object toward a shirtless boy standing to her left in shallow water. The boy observes while another child floats further in the pool. The camera remains stationary, capturing the scene from a top-down angle with poolside equipment visible in the background.

Two individuals in the pool are moving: one is reaching out with an arm (possibly swimming or interacting with the other person), and both exhibit locomotion through water displacement.

The pool water shows minor ripples, but the surrounding background elements (pool deck, walls, structures) remain stable with no uniform shifting. The water ripples are secondary to the main subject motion.


A man in a black suit and tie stands to the left of two seated individuals, pouring a liquid into a glass; the camera pans downward to reveal a red table with a bottle, empty wine glass, papers, and a pen, then shifts to a top-down view of the table setup.

Discrete solid objects include the bottle (held by a person in a suit) moving to pour liquid into a glass, and the person's hand manipulating the bottle. These movements are due to explicit physical forces (holding, pouring).

Background elements (walls with paintings, furniture) are static and do not shift uniformly. No fluid/environmental motion (fire, water flow, smoke) is observed.


A hand uses a colored pencil to color a black-and-white line drawing of a skull on paper. Initially, the pencil shades the diamond on the skull's forehead with blue, then fills the eye sockets with yellow and green, colors the flowers around the eyes pink, and outlines the nose and mouth in blue. The hand continues coloring the lower jaw and teeth. Finally, the hand holds up the completed colored skull, revealing detailed patterns and hues. The camera maintains a close-up perspective focused on the paper, slightly adjusting to follow the pencil's movements.

A hand holding colored pencils moves to color specific sections of the skull drawing on paper. The paper is held by a person at the end, but the dominant motion is the hand's controlled coloring actions.

The background (white paper on dark surface) is static; no shifting backgrounds or environmental fluids (fire, water, wind) observed.


A pair of adult hands places a small, rectangular metal object onto a worn metal surface within a wooden frame. The hands then slide the object back and forth across the surface, generating metal shavings. The hands are positioned centrally in the frame, with the wooden frame and workbench visible below. The camera maintains a close-up, steady angle focused on the hands and the metal surface throughout the sequence.

A pair of hands is actively manipulating a small, solid object on a metal surface, demonstrating precise physical interaction.

Static background elements (wooden structure, metal surface) show no shifting or fluid motion; no fire, water, smoke, or wind present.


A person in a white shirt holds a yellow book with red text, then lowers it out of view. They move their hands to wipe their face, then place both hands on their head, leaning forward. The background consists of vertical wooden panels. The camera remains static throughout.

A person in a white shirt is performing discrete movements: holding and shaking a box, clapping hands, and covering their face with both hands. These are solid, distinct object motions driven by the person's actions.

The wooden panel background shows no shifting or movement, and there are no fire, water, or wind elements present. This eliminates ambient environmental motion.


RAW CAPTION: Got it, let's break this down. The video starts with a person on a bicycle with a basket, maybe a delivery bike, in a snowy street. There are other pedestrians in the background. Then the scene changes to another part of the street where a person is riding a bike, and there's a street sign visible. Then it shifts again to a different street with more people and a bike with two people? Wait, no, let's check each frame.

First frame: A person (wearing dark clothes, maybe a helmet) is on a bicycle with a basket, on a cobblestone street with snow. A person in a green jacket and backpack stands to the right. Background has shops and pedestrians.

Second frame: The same bike? Maybe moving. Then third frame shows a person riding a bike on a snowy road, with people walking on the sidewalk. Fourth frame: The bike with two people? Wait, no, the first frames have a bike with a basket, then maybe a different scene. Wait, the user provided five frames (0 to 4.7 seconds). Let's list the key actions.

Frame 0: Person on bicycle (dark clothing, helmet) with a basket (green maybe?), stopped on cobblestone street with snow. Pedestrians in background, shops with red doors. Another person (green jacket, blue bag) stands to the right.

Frame 1: Bike starts moving, maybe turning. Person still on bike.

Frame 2: Scene shifts to a different street—now a person riding a bike (blue backpack) on a snowy road, with pedestrians on the sidewalk. Cars are visible in the distance.

Frame 3: Back to a cobblestone street, bike with two people? Wait, no, the description says "a person" on a bike in the first part. Wait, maybe the bike is a tandem? Wait, no, looking at the video description: "a person on a bicycle with a basket" in the first frames, then another scene with a person on a bike (blue backpack), then maybe a bike with two people? Wait, the user's frames:

0.0: bike with basket, person standing to the right.

1.3: bike moving, maybe the same person.

2.5: person on bike (blue backpack) riding on a snowy street with people walking.

3.6: bike with two people? Wait, the user's fourth frame (3.6s) says "a bike with two people" maybe? Wait, the user's input:

Frame 0: person on bike, basket, street with snow.

Frame 1: bike moving, same person.

Frame 2: another scene with a person (blue backpack) on bike, street sign, people walking.

Frame 3: bike with two people? Wait, the user's input says:

"Frame 2: [2.5 seconds] a person riding a bike with a blue backpack on a snowy road, with pedestrians on the sidewalk."

Then frame 3: "a bike with two people" (maybe the tandem bike? Or a person carrying a child? Wait, the first frames have a bike with a basket, then later a person on a bike.

Wait, the main subjects are the bicycle riders. Let's track their motion.

First, a person (wearing dark clothing, helmet) is on a bicycle with a basket. They start on a cobblestone street, then move forward. Then the scene shifts to a different street where another person (blue backpack) rides a bike through a snowy street with pedestrians. Then back to a cobblestone street, the first person (with basket) continues riding.

Wait, the user's frames:

0.0: Bike with basket, person in dark clothes, helmet, stopped on cobblestone street. A person in green jacket stands to the right. Background: shops, pedestrians.

0.3: Bike starts moving, person rides forward.

1.4: Bike moves further, street with snow, shops.

2.5: Scene changes to a different street (maybe a different location) where a person (blue backpack) rides a bike through a snowy street with pedestrians on the sidewalk.

3.6: Back to a cobblestone street, the first person (with basket) is riding, with another person (maybe a passenger?) on the bike. Wait, the user's input says "a bike with two people" in frame 3.6.

Wait, the user's input description:

"Frame 0: person on bike with basket (green), cobblestone street, snow. Person in green jacket stands to right.

Frame 1: bike moving.

Frame 2: person riding bike (blue backpack) on snowy road, pedestrians walking.

Frame 3: bike with two people on cobblestone street, moving."

Wait, the key is to describe the motion

Discrete solid objects include tricycle riders, cyclists, and pedestrians moving via explicit locomotion (biking, walking). Their motion is tracked with bounding boxes.

Background elements (buildings, sidewalks) remain static across scenes; snow is accumulated and not exhibiting fluid motion (e.g., wind-driven drift), thus not dominant ambient environmental motion.


In a ballet studio, two young dancers and a teacher stand at a barre. The left dancer, wearing a black leotard, lifts her right leg high with arms raised, supported by the teacher; the right dancer, in a gray top and blue shorts, lifts her left leg, then extends it outward. Both maintain poses while the teacher assists the left dancer’s position. The camera remains static throughout.

Two dancers (girl and adult) and a child are moving in ballet positions; legs are raised, turned, and positioned. The motion is due to human locomotion.

Background is static (window, wall do not shift). No fluid/environmental motion dominates; the dominant motion is from dancers.


A shirtless individual in gray shorts walks quickly from left to right across the frame, passing in front of seated people near musical instruments. A second person in dark clothing then walks in the same direction, moving from left to right. Throughout, a man in a red shirt remains seated at a table, while another in a black and white shirt sits near drum equipment. The camera maintains a fixed, low-angle perspective with no visible movement.

A person in shorts is stepping on a moving platform (like a skateboard), causing it to move back and forth. The person's motion is due to their own locomotion and the platform's movement.

No shifting background elements or fluid/environmental motion observed.


A person in a pink top and dark pants dances energetically, moving forward and backward while raising their arms, surrounded by other people in casual clothing who stand or sit near wooden structures in the background. A striped yellow-and-black hat lies on the ground in the foreground. The camera follows the dancer with slight shake, maintaining a medium shot.

A girl in a pink shirt is actively running, jumping, and interacting with others. Additional people (e.g., individual in yellow shirt) exhibit locomotion. All movements are solid, distinct object motions due to intentional physical actions.

No significant ambient environmental motion (fire, water, smoke, wind). Background elements (barn interior, hay bales, wooden structure) remain static with no uniform shifting or fluid dynamics observed.


An older man in a light gray shirt, dark shorts, and sneakers bends forward on a black mat, sits down, lies back onto the mat, and extends his arms upward. The camera remains static, capturing the sequence in a room with a yellow wall and wooden flooring.

A person is performing physical movements: sitting on a mat, transitioning to a prone position, and moving limbs (arms/legs). The person is a discrete, solid object with motion due to explicit physical actions (locomotion, posture changes).

Background elements (walls, floor) are static and show no uniform shifting or fluid/environmental motion (e.g., fire, water, smoke, wind).


In a squash court, two male players—one in light blue shirt and dark shorts, the other in dark shirt and dark shorts—engage in a rally. The player in light blue moves right to hit the ball, then the player in dark shirt follows left. The light blue player continues moving right while the dark-shirted player moves left, alternating hits as they traverse the court's red-lined wooden floor. The camera remains stationary, providing a fixed top-down view of the court's interior.

Two players (humanoids) and a racquetball are moving. The players are actively running, lunging, and striking the ball with racquets. The ball's trajectory and the players' movements are consistent with collisions and physical forces (e.g., hitting the ball, footwork).

The background consists of static walls and wooden flooring with no visible shifting or fluid motion (e.g., no fire, water, or smoke). The environment is indoor and rigid, with no environmental elements dominating motion.


A person's hand, clad in dark blue clothing, uses a carving tool to follow red outline lines on a light brown wooden surface. The hand moves steadily, guiding the tool along the contours of the drawn design, gradually shaping the wood. The camera maintains a close-up, top-down perspective throughout the sequence, focusing on the carving action without movement.

A handheld tool (likely a laser or etching device) is being moved across the stone surface, with the person’s head visible in the background but stationary.

The stone surface and surrounding environment show no significant fluid motion (e.g., fire, water, smoke). Background elements (stone, partially visible person) appear stable with no uniform shifting.


A group of approximately ten people, dressed in casual attire (t-shirts, dark pants, skirts), stand outdoors under a clear sky with sparse trees, holding large white pillows and black hats. They then move forward rapidly, engaging in a chaotic pillow-throwing and pushing motion, colliding as individuals jostle in the frame. The camera follows the crowd’s movement, exhibiting a slight shake as the action intensifies.

A crowd of people carrying and passing a large banner exhibit chaotic locomotion and object handling; discrete solid objects (people and banner) move due to physical forces and collisions.

The background (trees and clear sky) remains static with no uniform shifting. No fire, water, smoke, or wind dominates the scene.


RAW CAPTION: Got it, let's break this down. First, the video starts with two people standing on a grassy field near a baseball diamond. The first frame shows them together. Then the camera shifts to focus on one person—maybe the other leaves the frame. That person is wearing a light gray shirt, blue shorts, a cap, and dark shoes. They start holding a frisbee, then throw it. Wait, the actions: the first scene has two people, then the camera moves to show one person throwing a frisbee. Let's check the timestamps.

Frame 0: two people (one in white shirt, black shorts; the other in gray shirt, blue shorts) standing on grass. Frame 1: maybe the camera moves to one person. Frame 2: the person is standing, holding a frisbee. Frame 3: they prepare to throw. Frame 4: they throw the frisbee. Frame 5: after throwing, they walk back.

So chronological order: two people start on the field. Then one person (described in appearance) throws a frisbee, then walks away. Camera perspective: starts with two people, then focuses on one (so camera moves to follow the action, maybe a pan or cut? The description says "camera movement" so maybe it's a shift in focus. The rules say mention camera perspective and movement.

Background: grassy field with a baseball diamond, trees. Minimal background.

So the caption should be:

Initially, two individuals stand on a grassy field near a baseball diamond; one wears a white shirt and black shorts, the other a light gray shirt, blue shorts, and a cap. The camera shifts focus to the second individual, who holds a frisbee, prepares to throw, and then releases it, subsequently walking away.

Wait, check rules: chronological order. So start with the two, then camera moves to one, who throws the frisbee, then walks. Also, describe appearance (colors, etc.). Spatial relationships: in the first frame, they are together on the grass. Then the camera focuses on one (so he is in front, or the camera moves to him). The problem says "mention spatial relationships if relevant"—so in the first frame, they are standing together on the grass; then the camera moves to show one person throwing.

So let's structure:

At the beginning, two people are standing on a grassy field adjacent to a baseball diamond. One person is dressed in a white shirt, black shorts, and white shoes; the other wears a light gray shirt, blue shorts, dark shoes, and a cap. The camera then shifts focus to the person in the light gray shirt, who holds a frisbee, spins around, and throws it toward the outfield, followed by walking away.

Wait, in the frames: frame 0: two people; frame 1: one person (so the camera moved to focus on one). Frame 2: person holding frisbee; frame 3: prepares to throw; frame 4: throws; frame 5: walks. So the action is: the person throws the frisbee (starts holding, then throws, then walks).

Also, the appearance: light gray shirt, blue shorts, cap, dark shoes. The other person's shirt and shorts are mentioned in the first frame but maybe not in the later frames. Since the video shifts focus, the main subject is the person in gray.

Wait, the rules: "main subjects (people/animals/objects) in chronological order." So the primary action is the person throwing the frisbee. So the two people are initially present, then the focus moves to the one person who does the action.

So the caption:

Two individuals stand on a grassy field next to a baseball diamond; one wears a white shirt and black shorts, the other a light gray shirt, blue shorts, and a cap. The camera shifts to focus on the person in the light gray shirt, who holds a frisbee, winds up, and throws it, then walks away.

Check the rules:

a) Motion and behavior: two people start standing, then one throws, then walks. Chronological.

b) Appearance: color and size for main subjects. The main subject after the first frame is the person in gray. So mention his appearance.

c) Spatial: in the first frame, both on field; then camera focuses on him (so he's now the main subject, maybe he's in front of the camera).

d) Camera perspective: starts with two people (wide shot?), then shifts to the person (close-up or focus on him). So "the camera shifts focus to" or "the camera follows" or "cuts to".

e) Background minimal: baseball diamond, trees, grass.

f) Exclude text, names.

g) Don't output reasoning.

Putting it all together:

Initially

A person in a baseball uniform performs pitching motions, with visible locomotion (walking, throwing) and distinct object interaction (ball movement).

The background (trees, field, fence) shows no uniform shifting or fluid motion; no fire, water, or wind-driven phenomena observed.


A man in a gray shirt, dark pants, and brown shoes stands on a sidewalk in front of a store window, playing a flute. He remains stationary as a second person, wearing a black top and dark shorts, walks into frame from the right, bends down, and places an object into a bowl on the ground. The camera remains fixed throughout.

Two people: first person adjusts camera position (discrete hand movements), second person walks in, bends down, and interacts with a circular object on the ground.

The storefront glass and blue sign remain static across frames with no uniform background shift or fluid/environmental motion (fire, water, smoke, wind).


A dark-skinned hand mixes reddish-brown sauce with pieces of green vegetable on a yellow plate, moving in circular motions to coat the food. The hand repeatedly lifts and spreads the sauce across the plate, adjusting the placement of the vegetable pieces. The camera remains fixed in a top-down position, focusing solely on the plate and hand interaction.

A dark-skinned hand is actively moving across a yellow plate, spreading a thick reddish-brown sauce over pieces of food (likely meat or vegetables). The hand's motion is deliberate and discrete, driven by physical force.

The background (marble surface) is static with no uniform shifting, ruling out camera_motion. No fire, water, or smoke is present, so ambient_environmental is not dominant.


A person with a wristwatch and colorful wristbands adjusts a component on a red machine with a large black tire. They remove a black cylindrical object, hold it briefly, then reinsert it into the machine. The red frame, white cylinder, and metal parts of the machine are visible, with the person’s hands positioned in front of the machine. The camera maintains a steady close-up perspective on the hands and mechanical parts throughout.

Hands are moving in discrete, solid motion to manipulate components on the machine (e.g., tightening, adjusting parts), exhibiting clear physical interaction.

Static background elements (red machine structure, tire) show no uniform shifting or fluid environmental motion (e.g., no fire, water, smoke, wind).


A hand with light-colored nail polish holds a needle threaded with dark thread, inserting it into a beige fabric stretched in an embroidery hoop. The hand moves the needle through the fabric, creating a stitch near an existing small cross-stitch design featuring orange and brown threads. The hand adjusts the needle's position repeatedly, advancing the embroidery. The camera maintains a top-down perspective, focusing on the hand and the fabric with minimal background visibility.

A human hand and embroidery needle are moving in discrete, solid motions as the hand manipulates the needle to create stitches on fabric within an embroidery hoop.

The background consists of dark, static elements (e.g., furniture or walls) with no visible shifting or fluid motion (fire, water, wind). No ambient environmental phenomena are present.


The video begins with a black screen displaying the text "NEWS ANCHOR FAIL FROM FAILBLOG". It then transitions to a female news anchor with short dark hair, wearing a white shirt, seated in front of a backdrop featuring multiple television screens showing "Local 9" and "9" logos. The anchor remains stationary, facing forward, with slight head movements as she speaks. The camera maintains a static shot throughout, positioned at eye level with the anchor.

The news anchor is moving minimally (head nodding, mouth movement) due to speaking and gesturing. This is typical human locomotion.

Static studio background with no shifting or fluid motion. No fire, water, smoke, or wind present.


A person wearing a dark sleeveless top, black shorts with a blue stripe, and dark shoes stands on a concrete square in a grassy field. They begin with arms extended sideways holding a red ball, then step forward with their left foot, pivot, and release the ball. To the right of the square, a black bag, a pair of shoes, and a water bottle lie on the grass. The camera remains stationary, capturing the motion from a fixed perspective.

The person (a solid object) is moving by throwing a ball and stepping on a mat. The ball is visible at the time of throw and then leaves the frame. The dogs remain stationary.

No shifting background or fluid/environmental motion observed.


A man in a white shirt and dark shorts stands on a concrete circle within a green netted throwing area, picks up a red discus from the ground, spins clockwise multiple times, and releases the discus forward. Other individuals are visible in the background beyond the net. The camera remains stationary with minimal movement.

A person (batting subject) is moving: running towards the home plate, swinging a bat, and following through after contact. The motion is discrete and driven by physical locomotion and collision (bat-ball interaction).

The background includes a building and trees; no significant fluid motion (fire, water, smoke) or dominant wind effects are observed. Background elements remain relatively static with minimal visible swaying.


A person in a black tank top, green shorts, and blue sneakers crouches in a gym, then stands and pulls a black rope toward themselves. They walk forward, approaching the camera, which tilts upward as they get closer. The camera perspective shifts slightly, focusing on the person's upper body as they move.

A person is moving by pulling a cable and walking towards the camera, which is a clear example of locomotion by a discrete solid object.

The background (gym equipment, walls) is static with no shifting. No fluid or environmental motion (fire, water, wind) present.


Three men stand around a table; the man in blue handles items, the man in dark blue steps back and moves left across the table, while the man in striped shirt observes from the right. A seated person is visible in the foreground. Camera remains stationary.

Three individuals (two in blue shirts and one in black shirt) are moving: one stands and moves around the table, another is handling objects on the table, and the third is standing. The motion is due to explicit physical forces (walking, lifting, pushing).

The background (wall and banner) is static with no shifting or fluid motion. No fire, water, smoke, or wind present.


RAW CAPTION: Got it, let's break this down. First, the main subject is a person. They're wearing a sombrero, white tank top, black pants. The action: in the first frame, they're holding something (maybe a plate?) and then moving. Let's check the sequence.

Frame 0: Person standing, hands out. Frame 1: They raise both hands, maybe holding an object. Frame 2: Still moving, maybe tossing something. Frame 3: They're tossing a plate (since there's a plate in the air). Frame 4: Plate is mid-air, person has hands up. Frame 5: Plate is gone, person has hands raised.

So the motion is: starts with arms extended, then raises both arms while tossing a plate (which is in the air), then hands up as the plate moves away.

Appearance: sombrero (colorful, wide-brimmed), white tank top, black pants. Number: one person.

Spatial: background has shelves with various items (plates, books, etc.), but minimal description. Camera is static? The video seems to have a slight shake maybe, but the rules say mention camera perspective. The frames show a consistent view, so maybe static camera.

Now, chronology:

Starts with person holding an object (maybe a plate) with both hands extended. Then raises both arms upward while tossing the plate, which is airborne. Then the plate is moving away from them, and the person's hands are raised high.

Wait, in frame 0: hands out, maybe holding. Frame 1: hands up, maybe tossing. Frame 2: hands moving, plate in air. Frame 3: plate is in the air, person's hands are raised. Frame 4: hands up, plate still there? Wait, let's parse the frames.

Wait, the video frames:

[0.0] person stands, hands out (maybe holding an object)

[1.0] person raises both hands, object in hand?

[2.0] person moves, arms up, plate thrown?

[3.0] plate is mid-air, person has hands raised

[4.0] plate is moving down, person's hands up

[5.0] person has hands raised, plate out of frame

Wait, the key is the motion of the person and the plate.

The person, wearing a large sombrero, white tank top, black pants, starts with arms extended. Then raises both arms upward while tossing a plate, which flies through the air. As the plate moves away, the person's hands remain raised above the head.

Camera: seems to be a fixed position, no obvious movement, maybe slight shake.

Background: shelves with books and dishes, but minimal.

So the caption should be concise, chronological:

A person wearing a wide-brimmed sombrero, white tank top, and black pants stands in front of shelves. They extend both arms, then raise them upward to toss a plate, which arcs through the air. The person keeps hands raised as the plate moves away. The camera remains static with slight shake.

Wait, but rules say "briefly describe appearance and number". So "a person wearing a colorful sombrero, white tank top, black pants."

Check the rules:

a) Motion chronology: starts with arms extended, then tossing the plate.

b) Appearance: sombrero (colorful), white tank top, black pants.

c) Spatial: in front of shelves (but maybe just mention front of shelves as background).

d) Camera: static with slight shake.

e) Background minimal: shelves are there but not necessary, but maybe "in front of a shelf with various items".

Wait, the first frame: shelves are behind, so "in front of a shelf with books and dishes".

But rule e: keep background minimal unless essential. Since the shelves are part of the scene, maybe mention it briefly.

Putting it all together:

A person wearing a colorful sombrero, white tank top, and black pants stands in front of a shelf holding books and dishes. They extend both arms, then raise them upward while tossing a plate into the air. The plate arcs away as the person keeps hands raised. The camera is static with slight shake.

Wait, let's check the frames again. In frame 0: person has hands out, maybe holding a plate. Frame 1: hands up, plate in hand? Wait, no, the description says "a person... in front of shelves". The actions:

- Frame 0: arms extended (maybe holding an object)

- Frame 1: arms raised, object is being tossed

- Frame 2: arms up, object mid-air

- Frame 3: arms up, object still moving

- Frame 4: arms up, object is gone

Wait, the video shows the person tossing a plate. So the sequence is

The person is moving their arms and body, throwing a stuffed animal and a ball, which are moving through the air due to explicit physical forces (the throw).

The background (bookshelf and wall) is static with no shifting. No ambient environmental motion (fire, water, smoke, wind) is present.


A person in dark clothing sits, playing a large accordion with black and white keys. They continue playing, then expand the accordion's bellows, moving the instrument slightly to the left. The camera remains stationary, capturing the scene from a fixed angle.

The person (a solid object) is moving their hands and body to play the accordion, causing the bellows of the accordion to expand and contract.

The background remains static (lamp, framed photos, furniture) with no environmental fluid motion (e.g., smoke, water, wind).


RAW CAPTION: Got it, let's see. The task is to create a concise chronological paragraph for the video. First, look at the frames. The first frame shows a group of people on a stage with a checkered floor. There are several people, maybe 8 or so, standing around a circular area. The floor is checkered black and white, and there's a blue circle in the center with a logo. Then the next frames switch to a different scene: people outdoors, maybe a park or backyard with a wooden fence. They're moving, doing some dance moves. The text in Korean is there, but we have to exclude text recognition. So focus on the motion.

Chronological order: first scene is a group on a stage (circle area, checkered floor), then they move to an outdoor setting with a fence. The people are moving, dancing, raising arms, maybe jumping. Describe the subjects: main subjects are people, number maybe around 10-15, their appearance: in the first scene, white shirts and pants, some in different colors. Then outdoor: pink shirts, one with a yellow headband, green necklace. Movements: in first scene, standing in a circle, then next scenes dancing, arms raised, moving in unison. Spatial: first scene is a stage with audience around, then outdoor with fence in background. Camera perspective: first frame is top-down, then maybe handheld or moving camera. Need to keep background minimal.

So structure: Start with the stage scene: multiple people (around 8-10) on a circular platform with black-and-white checkered floor, some in white attire, standing in a circle. Then transition to an outdoor setting where the group (now more people, including those in pink shirts, one with yellow headband) dance energetically, moving arms and bodies in unison, with a wooden fence in the background. Camera shifts from top-down to dynamic handheld shots following the movement.

Check rules: exclude text, focus on motion and behavior chronologically. Mention appearance (colors), number, spatial relationships. Conclude with camera.

Let me draft:

The video opens with a group of approximately ten people standing in a circle on a black-and-white checkered floor platform, some in white tops and pants, while others wear varied colors; they remain stationary as an audience surrounds them. It then transitions to an outdoor scene where the group, now including individuals in pink shirts and one with a yellow headband, dance energetically, raising arms and moving in unison near a wooden fence, with camera movements shifting from top-down to dynamic handheld shots capturing their motion.

Wait, but need to check chronological order. First frame is stage, then next frames are outdoor. So first part is stage, then outdoor. Also, the number: in first scene, how many? Maybe 8-10. Second scene, more people. Movements: first scene stationary, then dancing.

Another point: in the second scene, the text is "모두 다함께!" which is "Everyone together!", but we exclude text recognition. So ignore that.

Check appearance: first scene, people in white (some), others in different colors (maybe one in pink? Wait, the first frame shows people in white, then the second scene has people in pink. So first scene: group in white, then second scene: group in pink, etc.

So revised:

The video starts with a group of approximately eight people standing in a circle on a black-and-white checkered floor platform, wearing white tops and pants, surrounded by an audience; they remain motionless. It then cuts to an outdoor setting where a larger group, including individuals in pink shirts and one with a yellow headband and green necklace, dance energetically, raising arms and moving in unison near a wooden fence, with the camera shifting from a top-down view to handheld shots following their dynamic movements.

Wait, "surrounded by an audience" – the first frame has audience in the background. So mention that briefly. But rule f says exclude text, so background descriptions minimal unless essential. The audience is part of the scene, but maybe just mention "surrounded by seated audience" briefly.

Also, in the second scene, the people are moving: "dancing energetically, raising arms and moving in unison".

Let's check number: first scene, maybe 8 people (since the image shows several, but not exact). Second scene, more people, maybe 10+.

Also, the movement: in the first scene, they are standing (motionless), then second scene dancing.

So putting it all together:

The video begins with approximately eight people standing in a circle on a black-and-white checkered floor platform, wearing white tops and pants, surrounded by a seated audience; they remain stationary. It then transitions to an outdoor scene where a larger group, including individuals in pink shirts

Solid objects (people) are moving through locomotion (dancing) and hand gestures, with clear bounding boxes tracking individual movements.

Background elements (walls, ground, blue building, grass, fence) show no uniform shifting or fluid motion; no fire, water, smoke, or wind dominant in the scene.


A person in a light beige shirt holds a spray can with a green nozzle, moving it to apply a dark substance onto a brown cardboard sheet resting on a table with metallic surfaces. The individual adjusts the can's angle while spraying, extending their arm leftward to cover the cardboard. The camera maintains a close perspective, slightly shifting to follow the hand’s motion throughout the spraying action.

A person is holding and moving a can with a green cap, indicating discrete solid object motion due to physical interaction (arm movement).

Background elements (walls, TV, table) are stationary; no fluid motion (fire, water, smoke) observed.


A person in a yellow and dark jacket sits at a table, initially holding a pen near their mouth before lowering it to fill in a Sudoku puzzle on an open newspaper spread before them. The person's hands move across the grid, writing numbers, while the newspaper rests on a table with a cup and small items visible in the background. The camera maintains a static close-up perspective focused on the person's hands and the puzzle.

A person's hand is moving discretely while writing on a newspaper, representing solid object motion due to physical forces (pen movement).

Background elements (table, cup, newspapers) are static with no uniform shifting or fluid motion (e.g., fire, water, smoke).


A girl with long dark hair and a dark blue shirt is seated at a table, holding a pink hairbrush. She raises the brush upward, brushes her hair, then lowers the brush to her side. The background features a plain white wall with faint pink decorations. The camera remains stationary throughout.

A person (discrete solid object) is moving: brushing hair, waving, leaning forward, and performing deliberate physical actions with their arms and upper body.

The background consists of a static white wall with pink decorative elements (shoes) that do not shift uniformly. No fluid or environmental motions (fire, water, wind) are present.


A young child in a green shirt with red stripes sits on a patterned floor, shifting their gaze from right to left while tilting their head slightly. The camera maintains a close-up perspective with minor movement.

The child is the only discrete object exhibiting motion; subtle head turns and slight body shifts indicate self-driven locomotion without external forces or collisions.

The background (patterned floor, furniture, and household items) shows no uniform shifting or fluid/environmental motion (fire, water, wind). All static background elements remain consistent across frames.


The video begins with a black screen, transitioning to a person in a yellow jacket and black shirt with a red and white graphic standing outdoors near a tree in a grassy area with houses in the background. The individual waves their right hand, then shifts position slightly while adjusting their jacket. The camera maintains a close-up perspective with minor shaking as it follows the person’s movements, keeping the background elements minimal.

The person is moving their arms and head in gestures, which is a discrete object moving due to explicit physical forces.

The background (trees, houses, grass) is static. No dominant fluid or wind motion observed, as the person's gestures are the main motion.


A woman in a gray long-sleeve shirt and black pants stands left of a man in a white graphic tee and dark pants near a white door; she swings her arms and exits left. The man turns toward a doorway where a third person in a dark shirt and red pants enters, then runs toward the doorway and exits right. A table with a brown bag and items remains in the foreground. The camera is stationary.

Multiple solid objects (people) move: the left person gestures and moves toward the table, the middle person interacts with the table, the right person enters and moves, and a person runs behind the table. These motions are distinct and trackable as discrete object physics.

The background elements (white doors, wall, dark room area) show no uniform shifting or fluid motion. No fire, water, smoke, or wind effects are visible.


Several soccer players stand together; a player in a blue and black striped jersey adjusts his collar, turns to face the camera, and smiles. The camera zooms in on this individual, highlighting his upper body against a blurred background.

Two individuals in sports jerseys (blue/black and red/black) exhibit discrete movement: the blue/black-jerseyed individual gestures and adjusts position, while the red/black-jerseyed individual interacts nearby.

The background features static blue banners and distant structures with no uniform shifting or fluid motion; no fire, water, or smoke observed.


RAW CAPTION: Got it, let's break this down. The video shows two people on a snowy street. First, the main subjects: a man and a woman. The man is wearing a dark jacket and light pants, holding a broom. The woman is in dark clothes, pushing a stroller.

Chronologically: At the start, they're on a road with snow on the sides. The man is sweeping with the broom, moving it back and forth. The woman is pushing the stroller, which is small, dark-colored. Then she moves behind him as he sweeps. The stroller is in front of the woman initially, and as she walks, she's following the man? Wait, no. Wait the sequence: in frame 0, man is sweeping, woman is pushing stroller. Then as time goes, man continues sweeping, woman walks behind him, pushing the stroller. So the motion is man sweeping (left to right maybe), woman pushing stroller towards the man or following.

Spatial relationships: woman is behind the man, pushing stroller. The stroller is in front of her, moving along with her.

Background: snowy street, houses, cars, trees. But keep it minimal. Background elements like snow, houses, cars are secondary.

Camera perspective: probably a fixed camera, since no movement described. The video shows a steady view.

Now, rules: concise, chronological paragraph. Start with main subjects, their actions, then spatial, then camera.

So structure: "A man in a dark jacket and light pants sweeps with a broom on a snow-lined road while a woman in dark clothing pushes a small stroller behind him. The man sweeps continuously, the woman follows, adjusting her pace to keep the stroller moving alongside him. The scene occurs on a residential street with snow banks and parked cars visible, captured by a stationary camera."

Wait, check the rules. Need to mention appearance (color, size, orientation). Man: dark jacket, light pants. Woman: dark clothing. Stroller: small, dark.

Also, chronological order: first, man is sweeping, woman pushing stroller. Then, as time progresses, man continues sweeping, woman moves behind him, pushing the stroller.

Wait, the video starts with man sweeping, woman pushing stroller. Then the woman starts walking behind the man (since she's moving in the same direction), pushing the stroller. So the motion: man sweeps with broom, woman pushes stroller in the same direction, moving behind the man.

Let's make it concise.

"A man in a dark jacket and light pants sweeps the snow-covered road with a long broom, moving the broom back and forth. Behind him, a woman in dark clothing pushes a small dark stroller, walking in the same direction. The woman follows the man, maintaining her position behind him as he continues sweeping. The scene is set on a residential street with snow banks along the sides, captured by a stationary camera."

Check if background is minimal. Snow banks, residential street, parked cars. But maybe mention "residential street with snow banks" as essential for setting, but rule says minimal unless essential for motion. The motion is on the road, so background is snow banks, which is part of the environment. But maybe keep it as "snow-lined road" or "residential street with snow banks".

Also, exclude text recognition, named characters. So no names.

Camera: stationary, since no pan or movement mentioned.

Let me check the frames. The video shows the man sweeping, the woman pushing the stroller, then the woman starts walking behind the man. Wait, in the first frame, both are moving. Let's see:

Frame 0: man is sweeping, woman is pushing stroller, both moving right.

Frame 1: same, woman is moving, stroller is moving right.

Frame 2: man continues sweeping, woman is behind, stroller is in front of her.

So the sequence is the man sweeping, the woman is pushing the stroller, then she moves behind the man as he sweeps.

So the caption should say: "A man in a dark jacket and light pants sweeps the snow-covered road with a long broom, moving the broom back and forth. A woman in dark clothing pushes a small dark stroller behind him, walking in the same direction as he sweeps. The woman follows the man, adjusting her pace to keep the stroller moving along the road. The scene occurs on a residential street with snow banks and parked cars visible, filmed with a stationary camera."

Wait, but need to be concise. Let's make it shorter.

"A man in a dark jacket and light pants sweeps the snow-covered road with a long broom, moving the broom back and forth. Behind him, a woman in dark clothing pushes a small dark stroller, walking in the same direction. The woman follows the man, maintaining

Two individuals are actively moving: one is shoveling snow with a broom (discrete object physics: human locomotion and tool use), and the other is pulling a wheeled snow blower (discrete object physics: human locomotion and equipment movement).

RAW CAPTION: Got it, let's tackle this. The video shows a group of people, likely a military band, standing in formation. The main subject is the band members. They're all in dark uniforms, probably black or dark blue, with some wearing caps. There are many of them, maybe around 20 or so. The conductor is in front, facing them, holding a baton. The band members are holding instruments—maybe saxophones or similar wind instruments.

First, describe the scene: the band is standing in a line, the conductor is in front, directing. Then, the motion: the conductor moves the baton, the band members are playing their instruments. Wait, the video frames show them holding the instruments, but are they playing? The captions say "chronological paragraph," so need to note the sequence.

In the frames, the conductor is leading, so maybe the band is preparing to play or playing. The background has a building, trees, but minimal. Camera perspective: the view is from the front, maybe slightly angled. Camera movement: the video might have a slight pan or static? The frames show a consistent view, so maybe static or slow pan. Wait, the user says "camera perspective and movement," so if it's a static shot, note that.

Let's structure:

- Number of main subjects: several uniformed band members (dark attire, caps, holding instruments), a conductor (dark uniform, baton).

- Chronological: The band stands in formation. The conductor holds a baton, facing the band. Band members hold instruments (likely wind instruments) in playing position. As the video progresses, the conductor moves the baton (indicating direction), and the band members' posture suggests they are following the conductor, possibly playing music.

- Spatial: Conductor in front of the band, which is arranged in rows.

- Camera: Static view from a slightly low angle, focused on the conductor and band.

Wait, the problem says "concise, chronological paragraph." Let's keep it short.

Main points:

- A group of uniformed musicians (dark attire, caps) stand in formation, holding instruments.

- A conductor (dark uniform, baton) stands in front, facing the band.

- The conductor gestures with the baton, leading the musicians.

- The band members hold their instruments in a playing posture, possibly playing music.

- Background: buildings and trees, but minimal.

Camera: Static perspective, slight angle, no significant movement.

Now, check rules:

a) Motion: conductor moving baton, band members holding instruments (implying action).

b) Appearance: dark uniforms, caps, instruments.

c) Spatial: conductor in front, band behind.

d) Camera: static, slight angle.

e) Background minimal.

f) Exclude text, names.

So the caption should be:

A conductor in a dark uniform holds a baton in front of a large group of uniformed band members, also in dark attire with caps, who stand in formation with wind instruments. The conductor gestures the baton, leading the band as they maintain their positions. The camera remains static, capturing the scene from a slight low angle.

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

A conductor in dark uniform stands facing a line of uniformed band members (dark attire, caps) holding wind instruments. The conductor moves a baton, directing the band members who remain stationary in formation. The camera is static, positioned at a low angle in front of the group.

Check for chronological order: The conductor leads, band follows. So start with conductor's action, then band's response.

"Conductor in dark uniform holds baton and directs a large group of uniformed band members (dark attire, caps) holding wind instruments. As the video progresses, the conductor gestures the baton, while the band members remain in formation with instruments poised for playing. The camera remains static, capturing the scene from a low angle in front of the group."

But need to be concise. Maybe:

A conductor in dark uniform stands facing a line of uniformed band members (dark attire, caps) holding wind instruments. The conductor moves a baton, directing the band as they maintain their positions. The camera is static, positioned at a low angle in front of the group.

Yes, that's good. Check all rules:

a) Motion: conductor moving baton, band members stationary (positional).

b) Appearance: dark uniform, caps, wind instruments.

c) Spatial: conductor in front, band behind.

d) Camera: static, low angle.

e) Background minimal (not mentioned except in the scene, but rules say minimal unless essential. The background is buildings/trees but not essential for motion, so maybe not included. Wait, the rules say "background descriptions minimal unless essential for understanding motion." Here, the motion is in the band, so background is not essential.

Individuals in uniform are turning and shifting positions slightly within the formation, indicating discrete locomotion by solid objects (people).

The background (buildings, trees) remains relatively static with no evidence of fluid or wind-driven motion. Minimal background shift is observed but consistent with subject movement rather than camera motion.


A person wearing dark pants and brown boots stands over two bottles on a concrete floor, one red and one dark. They lower an orange and gray chainsaw toward the bottles, then step on them, causing the bottles to break. The camera maintains a low angle, focusing on the lower body and the bottles as the person’s movements cause the bottles to shatter.

Person's legs shift position, and a handheld tool is manipulated (moved to interact with ground objects).

Background elements (box, sign) show no uniform shifting or fluid motion; no fire, water, or wind present.


Two teams of people, one in red shirts and the other in black shirts, engage in a tug-of-war on a grassy field. The red team members crouch low, gripping the rope and pulling with force, while the black team does the same. They strain against each other, leaning backward as they attempt to gain ground. The camera maintains a steady perspective but subtly shifts to follow the teams' movements, capturing their intense effort as the rope shifts back and forth.

Discrete solid objects: multiple people (e.g., red-shirted individual, others in blue/yellow) actively pulling a rope during a tug of war. Their motion is caused by physical force from the tug-of-war action and locomotion.

The background features a stable building and trees with no significant shifting or fluid motion. Minimal wind sway in foliage is present but not dominant, and no fire, water, or smoke effects are observed.


A woman in a blue patterned shirt and black pants bends down near a beige couch, then stands upright and gestures while a medium-sized brown and white dog stands on the wooden floor nearby. The woman shifts position slightly in front of a side table holding a lit lamp and framed pictures, with the dog remaining close to her. The camera remains stationary with minimal movement throughout the sequence.

Woman moving by walking and bending; dog stationary.

Background is stable; no ambient environmental motion (fire, water, smoke, wind) observed.


A man in a white polo shirt and blue jeans works at a long wooden table outdoors. He holds a screwdriver, places it on the table, picks up a screw, and adjusts it. He then lifts and slides a wooden plank along the table surface. A power drill rests to his right. The background includes stacked materials and greenery. The camera remains static, capturing the scene from a side angle.

A baby in white pajamas sits in a pink seat on a blue patterned bed. A child in a blue shirt enters from the left, reaches toward the baby’s legs, then moves away to the left, causing the baby to cry. The camera remains stationary with slight shake, capturing the interaction in a bedroom setting with toys and a window.

Two children: older child (blue shirt) moves around the bed, leaning toward infant; infant (pink outfit) reacts with facial expressions (smiling, crying) while seated on bed.

Background elements (bed, stuffed animals, window, table) remain stable with no uniform shifting; no fluids (fire, water, smoke) or wind-driven motion observed.


RAW CAPTION: Got it, let's break this down. The user wants a concise chronological paragraph about the video. First, identify the main subjects: hands and a tool (drill bit or something similar) working on a wooden piece. The video shows hands holding a curved metal object on a wooden block, then the tool is used.

Check the rules. Focus on motion in order. The hands are manipulating the metal object on the wood, then the tool is applied. Mention appearance: hands (color? maybe not necessary, but hands are visible), the wooden block has holes, the metal object is curved. Spatial: hands holding the metal piece, which is placed on the wooden block. The tool is brought down to interact with the metal.

Chronological: first, hands hold the metal piece on the wood. Then the tool (drill bit or similar) is used to work on the metal, rotating at 90 degrees as per the text, but we exclude text recognition. Wait, rule f says exclude text recognition, so ignore the French subtitles.

So sequence: Hands grip a curved metal object secured on a wooden block with multiple holes. A rotating tool is applied to the metal object, maintaining a 90-degree rotation angle as instructed, but since we can't mention text, just describe the action. The tool's motion is circular or rotational.

Camera perspective: close-up, focusing on the hands and the object. No movement mentioned, so maybe static close-up.

Background: minimal, blurred, but not essential. So focus on hands, metal, wood, tool.

Now, structure:

Start with the initial state: Hands hold a curved metal piece on a wooden block. Then the tool is applied: the rotating tool is pressed against the metal, moving in a circular motion. The hands adjust slightly to maintain the 90-degree angle (but since we can't mention the text, just the action). Wait, the text says "il est important de garder le meme angle de rotation de 90°" so the action is maintaining that angle, but we can't mention the text. So the motion is the tool being rotated at 90 degrees.

Wait, the video shows the hands holding the metal object, then the tool is used to work on it. The description needs to be chronological. Let's see the frames: first, hands hold the metal on wood, then the tool is applied, moving around.

Possible caption:

A pair of hands secures a curved metal object onto a weathered wooden block with multiple holes. The hands hold the metal in place while a rotating tool is applied to the metal's surface, moving in a circular motion to shape or modify it. The tool maintains a consistent 90-degree rotation angle as the hands adjust the metal's position relative to the block. The camera remains in a close-up, static position, focusing on the hands and the object's interaction.

Wait, but the rules say exclude text recognition, so "maintains a consistent 90-degree rotation" is based on the text, but maybe the video shows it. The original text says it's important to keep the angle, so the action is that the tool is used at 90 degrees. But since we can't mention the text, maybe just describe the tool's motion. Wait, the instruction says "Exclude text recognition", so don't reference the text, but the video might show the angle. Let's see the video: the hands are holding the metal, and the tool is moving in a way that the angle is 90 degrees. But since we can't mention the text, we have to infer from the motion.

Alternatively, "The hands adjust the metal piece on the wooden block while a rotating tool works on the metal's surface, maintaining a consistent angle of rotation." But maybe better to be more concise.

Wait, the key is to describe motion chronologically. Let's structure:

1. Hands hold a curved metal object on a wooden block.
2. A rotating tool is brought into contact with the metal object, applying pressure and moving in a circular motion.
3. The hands position the metal to keep the rotation angle consistent.

Camera: close-up, no movement.

So putting it all together:

A pair of hands secures a curved metal object on a weathered wooden block with multiple holes. The hands hold the metal steady as a rotating tool is applied to its surface, moving in a circular motion to modify the metal. The hands adjust the metal's position to maintain a consistent rotation angle. The camera remains in a close-up, static perspective throughout.

Check rules:
a) Motion in chronological order: yes, hands secure, tool applied, adjust position.
b) Describe appearance: hands, metal curved, wooden block with holes.
c) Spatial: metal on block, tool on metal, hands holding metal.
d) Camera: close-up, static.
e) Background minimal

Discrete solid objects include the hands manipulating the tool (chisel/file) and the wooden piece being shaped. Motion is deliberate, driven by physical force applied to cut/shape the wood.

The background consists of a static wooden workbench with no shifting elements, fluids, or environmental motions (fire, water, smoke, wind). Background elements remain stable throughout.


A group of people wearing winter coats, scarves, and hats run through a snowy street, moving rapidly in various directions; some carry large sacks while others push through the snow, with a few individuals embracing or holding onto one another. The scene transitions to a close-up of a person with a scarf, then returns to the crowd as more people join, moving urgently in the snow. The camera follows the chaotic motion with a slight shake and pan, capturing the group’s energetic movement through the snowy environment.
