RAW CAPTION: Got it, let's tackle this. First, the video starts with a hand holding a small object near a container. Let's see the sequence.

Frame 0: Hand with long nails (light pink) holds a small item (maybe a cotton swab) above a clear container with a lid. The container has a purple substance inside, and the lid is off. The background is light, maybe a surface.

Frame 1: The hand moves the item over the container, then the container's lid is placed down. Wait, maybe the hand is adjusting the container? The small item is moved towards the container.

Frame 2: The hand is still holding the item, maybe pressing it into the container? The lid is now on the container? Wait, the first frame shows the container open with a purple spot. Then the next frames show the hand moving the item into the container.

Frame 3: The hand is holding the item (which is now in the container, maybe a cotton swab with purple liquid). Then the other hand is coming in, holding a small container with a red dot? Wait, frame 3 shows a hand with long nails (light pink) and another hand with a red dot on the finger (maybe a small bead or dot). The container is clear, lid off.

Frame 4: The hand with the red dot is placed over the container, maybe dipping something? The action here is the hand moving the red dot towards the container. Then frame 5: the hand with the red dot is pressing into the container.

So chronological order: A hand with long light pink nails holds a small object (like a cotton swab) above a clear container with a purple substance inside. The hand moves the object towards the container, then the container's lid is placed down. Another hand appears with a red dot on the fingernail, which moves towards the container and dips into it. The hands interact with the container, moving the object and the red dot.

Appearance: hands have long nails, light pink. Container is clear, lid off initially, then lid placed. The small object is white (maybe a swab), purple substance in the container, red dot on the other hand's nail.

Spatial relationships: The hand with the swab is over the container, then the other hand with red dot moves towards the container.

Camera perspective: Close-up, top-down view, no movement mentioned. Background is a light surface, minimal.

Now, follow the rules. Focus on motion chronologically.

Start: Hand with long light pink nails holds a small white object above a clear open container with purple liquid. Hand moves the object towards the container. Then another hand with a red dot on the fingernail moves into the frame, positioning the red dot over the container. The second hand dips the red dot into the container.

Check rules: a) motion in order, b) appearance (light pink nails, clear container, purple liquid, red dot), c) spatial: hand with object over container, then other hand approaches, d) camera: close-up, top-down, no movement, e) background minimal, f) exclude text, etc.

Make sure it's concise. Let's draft:

A hand with long light pink fingernails holds a small white object above a clear container with purple liquid, then lowers the object into the container. Another hand with a red dot on the fingernail enters the frame, moving toward the container and dipping the red dot into the liquid.

Check if that's chronological. First action: hand holding object over container, then moves object into container. Then other hand comes, moves toward container, dips red dot.

Wait, in frame 3: the hand with red dot is moving towards the container. So the sequence is:

1. Hand with light pink nails holds object above container.

2. Hand moves object toward container.

3. Other hand with red dot enters, moves toward container.

4. Second hand dips red dot into container.

Also, the container's lid is placed down? Wait, in frame 1, the container has a lid (the small container with the lid on the surface, but in frame 0, the lid is off). Wait, frame 0 shows a small open container with purple liquid. Frame 1 shows the lid is now placed down? Maybe the hand is placing the lid.

Wait, let's recheck the frames:

Frame 0: Hand holds object (swab?) above a clear container (lid off, purple liquid inside), a lid is on the surface. Wait, no: the video description says "a small open container with purple liquid" and "a lid is on the surface" (like a lid on the side). Then frame 1: the hand is moving the lid into the container? Maybe not. Let me see the user's input:

Frame 0: a hand holding a small white object

Hands pour liquid from a glass into a bowl, then point and manipulate the bowl.

Background (white surface) is static; no fluid/environmental motion (fire, water, smoke, wind) detected.


A woman in a white top and dark pants stands on a stage, gesturing with her hands while speaking. She steps forward, turns slightly, and moves toward the right side of the stage. The camera pans left, revealing an audience member in a white and blue top bending down in the foreground. The camera then shifts back, showing the woman near a large screen displaying a person in a white shirt to her left.

A person (speaker) is walking on the stage and gesturing.

The stage backdrop and lighting are static with no fluid or environmental motion (fire, water, smoke, wind) detected.


The stainless steel refrigerator door opens, revealing illuminated shelves filled with bottles and containers; the camera pulls back to show the fully open fridge, then transitions to a wider perspective of the unit against a dark background.

A human hand is seen opening the refrigerator door, indicating discrete solid-object motion (locomotion via physical action). The refrigerator door itself moves mechanically but is part of the object's structure.

The kitchen background (walls, cabinets) remains static throughout the video; no fluid or environmental motion (fire, water, smoke, wind) is present.


A small child wearing a black shirt with pink and blue accents manipulates colorful puzzle pieces on a dark surface, picking up and positioning pieces into the puzzle structure; the camera maintains a top-down perspective with slight movement as the child continues the activity.

A child is manipulating puzzle pieces, moving hands to pick up, place, and arrange the pieces.

The background (table and fabric) is stationary; no uniform shifting observed. No environmental fluid motion (fire, water, smoke, wind) present.


A hand uses a knife to cut slits into multiple round, light brown dough balls arranged on a perforated tray. The hand moves methodically across the tray, making precise cuts on each dough ball. The camera maintains a close-up, top-down perspective with slight movement, focusing on the cutting action.

A hand holding a knife is moving to cut the bread rolls. The hand and knife are the discrete solid objects in motion, performing a cutting action on the stationary bread rolls.

No shifting backgrounds or fluid/environmental motion observed. The background (baking tray and counter) is static with no uniform shift. No fire, water, smoke, or wind present.


Two toddlers interact near a window: a child in a white t-shirt and orange striped pants faces a child in a red t-shirt with heart patterns, touching hands. The white-shirt child steps back, while the red-shirt child looks down and moves toward the camera. Background includes a white crib. Camera remains stationary with minimal movement.

Two children (discrete solid objects) interact: one child in red holds the other's hand, then they move together while maintaining contact. Motion is due to intentional locomotion and hand-holding.

Background elements (white railing, door, outdoor foliage) show no significant shifting or fluid motion. No fire, water, or wind-driven environmental effects are present.


A person in a white sweatshirt with dark stripes sits at a table covered with a lace tablecloth, shuffling and arranging red-backed playing cards. Their hands move the cards rhythmically, lifting and placing them while interacting with multiple card stacks. The table also holds a bowl and scattered items, with a tiled wall and refrigerator visible in the background. The camera maintains a close-up perspective with slight shaking throughout the sequence.

Person's hands and cards are moving as the person shuffles or sorts the cards on the table.

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


A man wearing a straw hat, white shirt, and dark vest stands in a large wooden barrel at night. A woman with long hair, white top, and denim shorts steps into the barrel from the left, approaching the man, who turns and interacts with her as they move within the barrel. The camera captures the scene from a fixed position with a slight shake, showing a crowd in the background.

Discrete solid objects (a man on a barrel, a woman approaching him) are moving via locomotion and interaction; their motion is tracked by bounding boxes without environmental interference.

No shifting static background elements (buildings, lights, fence remain stable). No fire, water, smoke, or wind motion observed.


RAW CAPTION: Got it, let's break this down. The video starts with a scene in a field. There are people on tractors. First, the first frame shows two tractors, maybe? Wait, the user provided the video frames. Let's check each frame.

Frame 0: A person on a red tractor, another on a green one, and a person standing. The background has fields and trees.

Frame 1: The red tractor is moving, maybe the person on it is waving a flag? Wait, the description says "a person waves a flag" in the first frame? Wait no, looking at the frames:

Wait, the first frame [0.0s] shows multiple people: a person on a red tractor, a person on a green tractor, and a standing person. Then [1.0s] shows the red tractor moving, maybe with a flag? Wait, the second frame (1.0s) has a person on a red tractor, a person standing, and the red tractor moving. Wait, the user's frame descriptions:

Looking at the user's provided frames:

Frame 0: Several people on tractors (red and green), a standing person. Background: field, distant trees, clear sky.

Frame 1: Red tractor moving, a person standing. Maybe a flag is waved by someone?

Wait, the problem says to focus on motion and behavior in chronological order. Let's track the sequence:

The video starts (0.0s) with a field scene: a red tractor with a person driving, a green tractor with a person, and a standing person. Then as time moves (0.1s, 0.2s, etc.), the red tractor moves forward, the person on the red tractor is driving, maybe a flag is waved? Wait, the user's frame 1 says "a person waves a flag" — wait no, the first frame description: [1.4 seconds] says "a person waves a flag" — wait no, the user's input shows:

[0.0 seconds]: A field with multiple people on tractors (red and green), a standing person. Background: open fields, distant trees.

[1.4 seconds]: A red tractor moves, person waves flag (maybe the person on the red tractor?), and a standing person.

[2.5 seconds]: Red tractor continues moving, people in the field (maybe others watching), the tractor is now in the middle of the field.

[3.6 seconds]: Red tractor moves towards the right, a person stands near the tractor.

[4.7 seconds]: Red tractor moves forward, people are on it (maybe two people?), and the tractor is heading towards the right side of the field.

Wait, the task is to describe the motion chronologically. Let's list the key elements:

- Main subjects: people on red tractor, people on green tractor (maybe), standing people.

- Motion: the red tractor moves forward through the field, passing by standing people. At one point, a person on the tractor waves a flag.

- Appearances: red tractor (color, size), people on it (wearing helmets or hats), standing people.

- Spatial: tractor moves from left to right, people stand in the field.

- Background: open fields, distant trees, clear sky — but keep background minimal.

- Camera movement: the camera follows the tractor, maybe panning right as the tractor moves.

Let's structure the caption:

Start with the initial scene: a red tractor with a person driving, a green tractor, and a standing person in a field. Then the red tractor moves forward, with a person waving a flag. The tractor continues moving, passing through the field, with other people visible. The camera follows the tractor's movement, panning right.

Now, check the rules:

a) Motion and behavior in chronological order: tractor starts stationary, then moves forward, person waves flag, continues moving.

b) Appearance: red tractor (color), people (wearing helmets? maybe), number: at least one person on red tractor, others standing.

c) Spatial: tractor moves from left to right, people standing near the tractor.

d) Camera perspective: follows the tractor, panning right.

e) Background minimal: fields, trees.

f) No text, names.

Now, write concise paragraph:

In a grassy field, a red tractor with a driver moves forward, passing a standing person; a person on the tractor waves a flag. The tractor continues across the field, with other individuals visible in the distance, as the camera pans right following its movement.

Wait, but need to check the frames:

Frame 0: Multiple tractors (red and green), people. Frame 1: red tractor moving, person waves flag. Frame 2: red tractor in field, people standing. Frame 3: red tractor closer, more people. Frame

Two people on a red tractor moving from left to right, and a person in a yellow jacket walking in the background.

The background (fields, trees, horizon) remains static and does not shift uniformly. No dominant fluid or wind effects are observed.


RAW CAPTION: Got it, let's break this down. First, the video shows a person in a gym. The person is wearing black clothes, maybe a black shirt and pants, and white shoes. They're on a track inside the gym. The main action is the person starting in a standing position, then bending down, then jumping or running. Wait, the sequence: at 0.0, they're standing. Then they go into a lunge or jump, then back to standing? Wait, let's check the timestamps. From the frames: [0.0] standing, [1.4] bent down (maybe a jump), [2.5] standing again, [3.6] jumping, [4.7] landing. Wait, the motion is: the person starts standing, then performs a jump or hop, then lands, then maybe repeats? Wait, the frames show the person in a gym with exercise equipment in the background. The main subject is a single person. They move from standing, then bend their legs (like a squat or jump), then jump, then land. Let's chronologically describe.

First, the person is standing on the track. Then they bend their knees, lowering their body (like a jump squat). Then they jump upward with both feet. Then they land back on the track, maybe with legs bent. The background has gym equipment, but keep it minimal. Camera is static? The frames don't show movement, so maybe the camera is fixed. The person's appearance: dark clothing (shirt and pants), white shoes. Spatial: on the track, in front of gym equipment. Chronology: starts standing, lowers body, jumps, lands. Now, put it all together concisely.

"An individual in dark clothing and white shoes stands on a gym track, bends their knees to lower their body, then jumps upward with both feet before landing back on the track. The background features gym equipment. The camera remains stationary, capturing the person’s motion from a fixed perspective."

Wait, check the rules. Rules say: focus on motion and behavior in chronological order. Briefly describe appearance (color, size, orientation). Mention spatial relationships if relevant. Conclude with camera perspective and movement.

Let me structure:

1. Main subject: person, dark shirt/pants, white shoes, single person.
2. Motion: standing, then bending (jumping motion), then jumping, then landing.
3. Spatial: on the track, gym equipment in background (minimal).
4. Camera: stationary (since the frames don't show movement).

So the caption should be concise. Let's make sure it's chronological:

"At the start, a person in dark clothing and white shoes stands on a gym track. They bend their knees, lower their body, then jump upward, landing back on the track. The background includes gym equipment. The camera remains stationary, capturing the motion from a fixed angle."

Wait, check the video. The video has frames 0 to 4.7. The person starts standing, then does a lunge/jump (maybe a jump squat), then stands, then jumps again? Wait, the first frame (0.0) is standing. Then 1.4: they're bent down (maybe in mid-jump or lunge). 2.5: standing again. 3.6: jumping. 4.7: landing. So the sequence is: stand, jump (bend), stand, jump (higher?), land. Wait, maybe it's a series of jumps. Let's say: the person performs a series of jumping motions, starting from a standing position, bending their knees to jump, then landing, and repeating.

Wait, the movement is: 0.0 - standing. 1.4 - knees bent, leaning forward (maybe preparing to jump). 2.5 - standing (after landing). 3.6 - knees bent again (another jump). 4.7 - landing. So it's a sequence of jumping up and down.

So the caption should describe that: person stands, bends knees to jump, then lands, then repeats. But the video is short, so the main actions.

Another angle: "A person wearing dark attire and white shoes performs repeated jumping motions on a gym track. They begin standing, lower their body by bending knees, then leap upward, landing back on the track. Gym equipment is visible in the background. The camera remains static, capturing the movement from a fixed viewpoint."

Check the rules:

- Motion and behavior in order: yes.

- Appearance: dark attire, white shoes (color, size, orientation? Size might not be necessary, but color is. Since it's a person, "dark clothing" is okay).

- Spatial: on the track, gym equipment in background.

- Camera: static (fixed perspective).

- Background minimal: gym equipment mentioned, but brief.

A person is running in place and performing exercises on a track. The motion is due to muscular effort and locomotion.

Background is static (gym equipment and walls remain stationary). No fluid or environmental motion observed (no fire, water, smoke, wind).


RAW CAPTION: Got it, let's see. The video starts with a person's hands on a cutting board with raw meat. The person is wearing a white shirt and a watch. They're handling the meat, probably cutting or arranging it. Let's check the frames. First, they hold a piece, then move it, split it into two. The meat is red, with some fat, on a white cutting board. The background is a dark countertop. The camera is top-down, maybe slightly moving? Need to describe chronologically: the hands manipulate the meat, separating it into two pieces. Appearance: hands, white shirt, watch, red meat with fat, white board. Spatial: hands in front of the board. Camera: top-down, maybe slight focus on the hands. Background minimal, just the counter. So the caption should be concise. Let's structure it:

A person wearing a white shirt and a wristwatch manipulates raw red meat with visible fat on a white cutting board, separating a piece into two portions with their hands. The meat is arranged on the board, with the hands moving the pieces to the left and right. The camera maintains a top-down perspective with minimal movement, focusing on the cutting board and hands.

Wait, check rules: chronological order, motion and behavior. First, the hands are holding a piece, then separating it. So: The person's hands position and separate a large piece of red raw meat with a white fat layer into two equal portions on a white cutting board, moving the meat pieces to the right and left. The camera stays top-down, focusing on the board.

Let me make sure. Frame 0: hands holding meat. Frame 1-2: hands manipulating. Frame 3-4: separating into two. So motion: hands separate the meat into two pieces. Appearance: meat is red, with fat, on white board. Spatial: hands work on the board. Camera: top-down, no major movement. Background is dark counter, but minimal.

So the caption should be:

A person wearing a white shirt and a wristwatch uses their hands to separate a large piece of red raw meat with visible fat into two equal portions on a white cutting board, moving the pieces apart to the left and right. The camera maintains a top-down perspective with slight focus shifts, keeping the cutting board and hands in view.

Wait, the rules say exclude named characters, so "a person" is fine. Also, number: "a large piece" becomes two. Chronological: starting with holding, then separating into two. So the description should be in order. Let's check the exact sequence: frame 0: hands holding, frame 1: hands pressing, frame 2: hands moving the meat, frame 3: split into two, frame 4: showing two pieces. So the action is separating the meat into two.

So the caption: A person uses their hands to split a large piece of red raw meat with a white fat layer into two equal portions on a white cutting board, moving the pieces apart. The camera remains in a top-down position, focusing on the hands and meat.

Wait, maybe more precise. Let's see the video: at start, hands hold meat, then press to cut, then move the two pieces. The meat is on the board, so the hands are manipulating the meat. The meat has visible fat, red color. The board is white with some red juice. Background is dark, but not important.

So the caption: The person's hands separate a red raw meat piece with visible fat into two portions on a white cutting board, moving the pieces to the right and left. The camera maintains a top-down view with minimal movement, centered on the board.

Wait, the output must be a concise paragraph. Let's try:

A person wearing a white shirt and a wristwatch separates a large piece of red raw meat with visible fat into two equal portions on a white cutting board, moving the meat pieces to the left and right. The camera stays top-down, focusing on the hands and the board.

But rules say "briefly describe their appearance and number (color, size, orientation)". The meat is red, large piece, split into two. The person's hands: wearing white shirt, watch.

Also, "spatial relationships: in front of, to the left". The meat is on the board, hands in front.

So putting it all together:

A person wearing a white shirt and wristwatch manipulates a large piece of red raw meat with visible fat on a white cutting board, splitting it into two portions and moving the pieces to the left and right. The camera maintains a top-down perspective with slight movement, centered on the board and hands.

Wait, but the rules say "DO NOT output your reasoning". So the final caption needs to be concise, following all rules.

Let me check the example rules again. Focus on motion and

Hands are manipulating raw meat pieces, repositioning and separating them on a cutting board.

Background (countertop, kitchen surroundings) is static; no fluid or environmental motion (fire, water, wind) detected.


In a gymnasium, a girl in a white shirt and dark pants twirls a baton while a boy in a white shirt with red pants and dark pants holds a baton; they move across the floor as onlookers observe. The scene transitions to a group of children in black shirts and khaki pants, standing in a circle, holding batons and facing an instructor. The camera shifts from the two individuals to the group, capturing their positions and actions.

Solid objects (people) are moving: two individuals engage in martial arts practice (kicking, striking), while a larger group claps and performs synchronized movements. All motions are due to human locomotion and physical interactions.

Background elements (walls, doors, gym floor markings) show no uniform shifting or fluid motion (e.g., no fire, water, smoke, wind). Static background remains consistent throughout frames.


RAW CAPTION: Got it, let's break this down. The video starts with a close-up of hands playing a guitar. The hands are using a cloth, maybe for cleaning or polishing the guitar. The cloth is light-colored with a pattern. Then the camera shifts to show a person in historical clothing—like a dark outfit with a ruffled collar—holding the guitar. The person is seated, and the guitar is being played. The background is dark, so focus is on the subject. The camera first shows the hands close up, then pulls back to show the person. Need to mention the motion: hands moving over the guitar with cloth, then the person's posture. Spatial: hands in front, then person holding guitar. Camera starts close-up, then zooms out. Let's structure it chronologically.

First part: Close-up of hands (dark skin) using a light patterned cloth on the guitar's body. Then the camera pulls back to reveal a person wearing dark historical attire with a ruffled collar, seated and holding the guitar. The person's hands continue the motion of cleaning or polishing the instrument. Background is dark, minimal details. Camera movement: starts with close-up, then slight zoom out to show the person.

Check rules: a) motion in order: hands with cloth, then wider shot. b) appearance: hands (dark), cloth (light patterned), person (dark historical clothes, ruffled collar). c) spatial: hands in front of guitar, person holding guitar. d) camera: starts close-up, then zooms out. e) background minimal. f) exclude text/names.

Now form a concise paragraph. "Close-up of dark-skinned hands using a light patterned cloth to polish a wooden guitar; the hands move rhythmically over the instrument's body. The camera then zooms out to reveal a person in dark historical attire with a ruffled collar, seated and holding the guitar while continuing the polishing motion. Background remains dark and indistinct, emphasizing the subject's actions. Camera movement transitions from tight close-up to a slightly wider shot."

Wait, need to make sure it's chronological. First the hands close up, then the wider shot. The person is the main subject. Also, "polishing" might be inferred, but the video shows hands on the guitar with cloth. Maybe "rubbing" instead of polishing? But the action is using the cloth on the guitar. Let's check the video frames. Frame 0-5 show hands with cloth on guitar. Then frame 5 shifts to a person (the person's face is visible now). So the sequence is: hands close-up, then pull back to show the person.

So the caption: "Close-up of dark-skinned hands using a light-colored patterned cloth to rub a wooden guitar's body; the hands move back and forth over the instrument. The camera then pulls back slightly to reveal a person in dark historical attire with a ruffled collar, seated and holding the guitar as the hands continue the motion. Background remains dark and unobtrusive, focusing on the interaction. Camera transitions from tight close-up to a wider shot."

Check length. Needs to be concise. Let's shorten: "Close-up of dark-skinned hands rubbing a wooden guitar with a light patterned cloth; hands move rhythmically over the instrument. The camera then zooms out to show a person in dark historical clothing with a ruffled collar, seated and holding the guitar while the hands continue polishing. Background is dark, minimal details. Camera shifts from close-up to wider shot."

Wait, "polishing" might be accurate. The cloth is used on the guitar, so polishing. But maybe just "rubbing" is safer. Let's see. The video shows the cloth moving over the guitar. So "rubbing" or "cleaning". But the action is the hands using the cloth on the guitar. So "dark-skinned hands use a light patterned cloth to rub the wooden guitar's body; hands move back and forth. Camera pulls back to reveal a person in dark historical attire with a ruffled collar, seated and holding the guitar while the hands continue the motion. Dark background, camera transitions from close-up to wider view."

Make it flow chronologically. First part: hands close up. Second: camera zooms out to person. So:

"Close-up of dark-skinned hands using a light patterned cloth to rub a wooden guitar; hands move rhythmically over the instrument. The camera then zooms out to reveal a person in dark historical clothing with a ruffled collar, seated and holding the guitar as the hands continue the motion. Background remains dark and indistinct. Camera transitions from tight close-up to a slightly wider shot."

Yes, that seems to fit. Check rules. a) motion in order: hands rubbing, then person visible. b) appearance: hands (dark), cloth (light patterned),

A person's hands and a violin are visible, with the hands moving to play the violin (bowing motion) and adjusting the instrument's position.

The background is dark and static with no fluid environmental motion (fire, water, smoke, wind) or shifting elements; the scene lacks prominent ambient effects.


The video shows a group of people bent over on the floor in a gym, with a man in a black shirt and dark pants walking through them. The man gestures as he moves left to right, passing near a wooden bench and a blue mat where one individual performs a handstand. Several individuals, including those in red, blue, and gray shirts, maintain bent postures or are positioned on the floor, surrounded by dumbbells and exercise balls. The camera remains stationary, capturing the scene from a fixed perspective.

Multiple individuals are performing physical exercises (e.g., bending, lifting), with movements consistent with locomotion and applied force.

The background elements (e.g., 'STREAMFIT' banner, walls, floor) show no uniform shifting or fluid motion; no fire, water, smoke, or wind is present.


Two individuals sit on the ground; one wears a vibrant, multicolored patterned outfit and holds a large, multicolored bowl, while the other, dressed in a black-and-white top and white pants, plays a wooden xylophone with mallets. The camera pans right, focusing sequentially on the second individual’s hands striking the instrument. Spatially, the xylophone player sits to the right of the first person, with minimal background details visible. The camera movement is a slow pan right with slight shake.

Two individuals playing musical instruments: one on a drum (left) and one on a marimba (right). The marimba player's hands and mallets move rapidly to strike keys, while the drum player manipulates the drumhead. All motions are discrete, solid-object movements.

No significant shifting background or fluid motion. Background elements (bicycle, wooden structure) remain static relative to the scene. No fire, water, smoke, or wind present.


A person in dark clothing sits on a chair, strumming a white and brown electric guitar. Their left hand moves along the fretboard while the right hand strums, positioned with the guitar angled toward a black amplifier to the right. The room has a tiled floor and minimal background elements. The camera remains static, capturing the scene from a slightly low angle with no noticeable movement.

A person playing an electric guitar shows discrete motion of hands strumming/picking and fretting on the instrument, representing solid object interaction.

The background (walls, floor, furniture) remains static across frames with no uniform shifting, indicating no ambient environmental motion (e.g., fire, wind).


A person in dark shirt and shorts sits on a striped board, then rises and walks toward another individual in a white shirt and shorts standing nearby; the second person also moves. The camera remains steady with slight shake, capturing the action from a medium distance.

Two people (one in dark shirt, one in white shirt) are moving: the seated person stands and runs away from the bicycle; the standing person walks away.

The background rocks and grass are static; the ocean shows minor wave motion but not dominant.


A single swimmer, wearing a black waistband, moves underwater in a pool, executing a stroke with arms pulling through water and legs kicking. The swimmer’s body remains horizontal, creating bubbles and ripples as they propel forward. The blue tiled pool floor is visible beneath them. The camera maintains a steady underwater perspective, capturing the swimmer’s motion from a fixed angle.

A single swimmer is visible, moving through the water with consistent arm and leg motions, indicating active locomotion.

The background consists of static pool tiles that do not shift uniformly, indicating no camera-induced motion. The water is present but the dominant motion is not solely driven by fluid dynamics; the swimmer's movement is the primary action.


Three individuals stand behind a studio desk, each holding red bags; the left person wears a dark suit, the middle individual wears a red top with a green hard hat, and the right person wears a black top with a green hard hat. The camera zooms in on the right individual, who adjusts a green rope while smiling. The scene returns to the group, where the left person shakes a red bag while the others hold their bags. The camera shifts between wide shots of the group and a close-up of the right individual. The background features a city skyline, and the overall setting remains consistent throughout.

Three individuals in red jackets and a woman in a black top/green hat are moving; their motions include gesturing, holding objects, and positional shifts within the studio.

The cityscape background remains static; no shifting elements or fluid/environmental motion (fire, water, smoke, wind) is observed.


Three children stand in front of a wall with hanging fabric; the left child raises their arm, the middle child moves their head, and the right child shifts position. The scene transitions to a white screen. The camera remains stationary throughout.

Three individuals are standing and displaying facial expressions and slight head movements.

The background (wall decorations and curtain) is static with no environmental motion observed.


A young child with curly hair, wearing a gray hoodie, sits at a dark table, arranging green puzzle pieces onto a colorful puzzle base featuring a yellow character. The child moves their hands, placing pieces with both hands, then picks up a green piece and positions it on the puzzle. The background is a plain brown wall. The camera maintains a static, top-down perspective throughout.

A child is actively manipulating jigsaw puzzle pieces with their hands, moving discrete solid objects (puzzle pieces) via physical interaction.

The background consists of a static wall and table with no shifting or fluid motion (e.g., no fire, water, smoke, or wind).


RAW CAPTION: Got it, let's tackle this captioning task. First, I need to focus on the main subject, which is the person installing flooring. The video starts with a top-down view of a room where the person is working. The person's hands are moving—using a tool, maybe a hammer or something, to adjust the floorboard. They lift a section of the floorboard, revealing the underlayment or subfloor. Then they smooth it out. The tools on the floor: a yellow and black drill, a stapler, etc., but background descriptions should be minimal, so maybe just mention the tools briefly as context.

Wait, the rules say minimal background unless essential. So the main motions: hands working on the floorboard, lifting and adjusting. The person's arms are visible, so maybe "a person's hands" or "an individual". The flooring has a pattern, light-colored with some texture. The camera is top-down the whole time, no movement mentioned. Let's structure it chronologically.

Start: Person's hands use a tool to adjust flooring piece. Then lift the edge of the flooring to reveal subfloor, then smooth the flooring into place. The tools on the floor are in the foreground but maybe not necessary to detail. Camera is top-down throughout.

Check rules: chronological, motion of main subject. So sequence: hands working, lifting, adjusting. Spatial relationships: hands on the floor (top-down view, so the person is kneeling, hands near the wood frame of the room).

Let me draft:

A person's hands adjust a light-colored patterned flooring piece on a wooden subfloor, using a tool to secure it. The hands lift the edge of the flooring to reveal the subfloor, then smooth the piece into place. Tools like a yellow drill lie on the floor near the wooden frame. The camera maintains a top-down perspective throughout, capturing the installation process.

Wait, but need to be concise. Let's make it shorter. The first frame shows the person starting to work. Then hands use tool, lift, adjust, smooth. Mention the flooring's appearance briefly.

Wait, the video description has frames 0 to 5.0. So in the first part, the person is working on the floor. Let's see:

In the video, a person's hands manipulate a light-colored textured flooring piece on a wooden subfloor. The hands use a tool to secure the flooring along the edge of a wooden frame, lift the flooring to expose the subfloor, and then smooth it back into place. Various tools, including a yellow drill, are visible on the floor nearby. The camera remains stationary in a top-down position throughout the sequence.

Hmm, but the rule says "briefly describe appearance and number". So the person's hands are the main subject. Number: one person. Color: hands (maybe not specify color, but the flooring is light-colored with texture). Orientation: hands working on the floor.

Also, spatial: the hands are on the flooring, near the wooden frame. The tools are on the floor, which is the lower part of the frame (since it's top-down).

Let's check if background is minimal. The floor is visible, tools on floor, so maybe mention the floor's texture as part of the setting.

Wait, the rules say "background descriptions minimal unless essential for understanding motion". So the wooden frame is part of the structure, essential for understanding the installation.

So revised:

A person's hands adjust a light-colored textured flooring piece on a wooden subfloor, using a tool to secure it along the edge of a wooden frame. The hands lift the flooring to expose the subfloor, then smooth the piece back into place. Tools like a yellow drill lie on the floor nearby. The camera remains stationary in a top-down position throughout.

Check for conciseness. Let's see if "adjust" is the right term. In the first frame, the person is using a tool to work on the edge. Then lifting the flooring. So the actions are: working (using tool), lifting, smoothing.

Maybe: A person's hands use a tool to secure a light-colored textured flooring piece along the edge of a wooden frame on a subfloor. The hands lift the flooring to expose the subfloor, then smooth it into place. Tools including a yellow drill are visible on the floor below. The camera maintains a top-down perspective without movement.

Wait, "flooring installation" is text in the video, but rule f says exclude text recognition. So ignore that.

Also, the rule says "main subjects (people/animals/objects)"—the main subject is the person, but maybe the flooring is the object. So the hands are the main subject.

Let's try to make it concise and chronological:

A person's hands adjust a light-colored textured flooring piece on a wooden subfloor, using a tool to secure it. The hands lift the edge of the flooring

A person (discrete solid object) is moving their hands and body to mark and adjust the floor with tools (tape measure, pencil).

The background (wooden floor, structural elements) is static; no uniform shifting or fluid motion (fire, water, smoke) is observed.


RAW CAPTION: Got it, let's tackle this. First, identify the main subjects: three kids and a dog. The video starts with the kids standing close. The kid in black shirt (with "28" maybe) is tall, wearing jeans. The middle kid in dark shirt and light pants is holding something, maybe a stuffed toy? Wait, the action: the kid in the middle is interacting with the tall kid. Then, the kid on the left in orange shirt is moving. The dog is in the background.

Chronological order: At the start, kids are standing. Then the middle kid (dark shirt) is holding something, maybe a toy, and moves towards the tall kid. Then the kid in orange shirt is involved. The dog is there but maybe not moving much. The camera perspective—looks like a handheld shot, slightly shaky. Background is a room with shelves, maybe a laundry area? But keep background minimal.

Need to describe motion: The kids are moving, interacting. The dog is in the lower right, maybe watching. The camera moves a bit, maybe pans or shakes. Let's structure:

Three children and a dog are in a room. The tallest child (wearing a black and white shirt with "28" and jeans) stands to the right. A shorter child in a dark shirt and light pants holds a small object, moving towards the tallest child. Another child in an orange shirt and dark jacket stands to the left, adjusting position. The dog is in the foreground right, looking up. As the children shift, the middle child steps back, the tall child turns slightly, and the left child moves closer. The camera remains steady with slight shake, capturing the interaction in a medium shot.

Wait, check rules: concise, chronological, main subjects motion. Background minimal. So focus on kids' actions. Let's make it shorter.

Three children interact in a room: a tall child (black/white shirt, jeans) stands right, a shorter child (dark shirt, light pants) holds an object, moving toward the tall child, and a third child (orange shirt, dark jacket) shifts position left. The dog remains in the foreground, observing. The camera is handheld with slight shake, maintaining a medium shot throughout.

Wait, check if "28" is essential? Rule f says exclude text recognition. So the shirt has some text but we can say "black and white shirt with a number" but rule f says exclude text recognition, so maybe just "black and white shirt" without the number. Wait, rule f: "Exclude text recognition, named characters, or stylistic analysis." So the number on the shirt—since it's text, we don't mention it. So the tall child is wearing a black and white shirt, jeans.

Let me revise:

Three children interact in a room. A tall child in a black and white shirt and jeans stands to the right. A shorter child in a dark shirt and light pants holds a small object, moving toward the tall child. A third child in an orange shirt and dark jacket shifts position to the left. A dog in the foreground right observes. The children's movements are dynamic, with the middle child stepping back and the left child adjusting. The camera is handheld with slight shake, capturing the scene in a medium shot.

Check chronology: First, they are standing. Then the middle child moves toward tall, then maybe the tall child reacts. The left child moves. Then maybe the middle steps back. So "the middle child moves toward the tall child, then steps back". The dog is present.

Another attempt:

Three children and a dog are in a room. The tallest child (black and white shirt, jeans) stands right. A shorter child (dark shirt, light pants) holds an object, moving toward the tall child, then steps back. A third child (orange shirt, dark jacket) moves left. The dog remains in the foreground, looking up. The camera is handheld with slight shake, capturing the interaction.

Yes, that's concise, chronological. Mention spatial relationships: "tallest child stands right", "shorter child moves toward tall child", "third child moves left". Dog in foreground.

Check rules:

a) Motion and behavior: children moving, dog observing.

b) Appearance and number: three kids, dog. Described.

c) Spatial: tall child right, middle child moving toward, third left.

d) Camera: handheld, slight shake, medium shot.

e) Background minimal: "room" is enough, don't go into shelves.

f) Exclude text: so no "28".

g) No reasoning.

So final:

<caption_output>Three children interact in a room: a tall child in a black and white shirt and jeans stands to the right. A shorter child in a dark shirt and light pants holds an object, moving toward the tall child then stepping back. A third

Three children are moving: one in dark shirt is being helped to stand and then plays with the others, showing interactions like pushing, pulling, and jumping.

Background elements (walls, shelf, cage) are stable with no uniform shifting. No fire, water, smoke, or wind detected.


A pair of hands manipulates a red and blue circular textile piece on a light gray surface. The left hand holds a white crochet hook near the edge, while the right hand adjusts and pulls maroon yarn through the piece. A gold needle lies nearby on the surface. The camera maintains a static top-down perspective throughout.

Two hands (one holding a crochet hook, the other managing yarn) are manipulating a crocheted circular object and red yarn to create or adjust it.

The background (table surface) is static with no shifting elements. No fire, water, smoke, or wind is present.


A man in a blue shirt and jeans, carrying a child in a purple and green top on his back, crouches on a sandy beach. He picks up a purple toy and places it near an orange sand structure while the child shifts position on his back. The man then stands, continuing to arrange colorful toys around the structure. The camera follows his movements with slight adjustment, capturing the ocean in the background.

A man (in blue shirt) and a child on his back interact with a toy structure (orange) and other beach toys. The man moves his hands to adjust the toy, causing discrete object motion.

Background shows ocean waves and sand; no significant fluid or wind-driven motion dominating the scene. Waves are present but not the primary motion.


RAW CAPTION: Got it, let's break this down. The video shows a split screen: left is sheet music titled "Menuett (L'ave de Guitarre)" by Robert de Vise, right is a close-up of a hand playing a guitar. The hand is on the fretboard, fingers moving to press strings. Need to describe the motion chronologically.

First, identify main subject: a hand (right side). Appearance: human hand, fingers pressing guitar strings. Number: one hand. Motion: fingers moving up and down the fretboard, pressing different frets. Spatial: the hand is on the guitar, which is positioned on a table. Background: left side is sheet music, but per rule e, minimal background description. Camera: close-up, static? The frames don't show camera movement, so maybe static or slight shake? Wait, the rules say camera perspective and movement. The video is split screen, so camera perspective is close-up on the hand and guitar, split with sheet music.

Check rules: a) motion in chronological order. So the hand's actions: fingers moving, pressing strings. b) appearance: hand, guitar (color? light-colored guitar, but maybe not essential). c) spatial: hand on guitar, sheet music on left. d) camera: close-up, split screen. e) background minimal. f) exclude text recognition.

So structure: start with the hand playing guitar (motion: fingers pressing frets, moving up/down), then mention the sheet music on the left (but only if essential). Since the sheet music is part of the split screen, maybe mention the layout but keep minimal.

Wait, the rules say "background descriptions minimal unless essential for understanding motion". The sheet music is part of the scene, but is it essential for motion? Maybe not, but the split screen is part of the scene. Hmm. The main action is the hand playing.

So draft: A hand with visible fingers presses strings on a light-colored guitar, moving up and down the fretboard in rhythmic motions. The scene is split-screen, with sheet music displayed on the left. The camera maintains a close-up perspective of the hand and guitar, showing consistent finger movements without significant camera movement.

Check rules:

a) motion chronologically: hand presses strings, moves up/down.

b) appearance: hand (no color specified, just human hand), guitar (light-colored, strings visible).

c) spatial: hand on guitar, sheet music on left.

d) camera: close-up, split screen.

e) background minimal (sheet music is in background but it's part of the split, so maybe okay).

f) exclude text recognition, so don't mention "Menuett" etc.

Wait, the rules say "exclude text recognition", so don't talk about the sheet music's text. So just say "sheet music is visible on the left" without naming it.

So revised: A hand presses strings on a light-colored guitar, fingers moving up and down the fretboard in a rhythmic motion. The scene is split-screen, with sheet music visible on the left. The camera remains close-up and static, focusing on the hand's movements on the guitar.

Check if that's concise. Let's see.

Main subjects: hand, guitar. Motion: fingers moving on fretboard. Appearance: hand (human), guitar (light-colored). Spatial: hand on guitar, sheet music on left (in split screen). Camera: close-up, static.

Yes. Now, make sure chronological order: the hand is pressing strings, moving up/down. So the caption describes the sequence: hand moves fingers to press strings, then repeats.

Another point: the hand's position changes as it moves along the fretboard.

So final caption: A hand with visible fingers presses strings on a light-colored guitar, moving up and down the fretboard in rhythmic motions. The scene is split-screen, with sheet music displayed on the left side. The camera maintains a close-up perspective, focusing on the hand's movements without camera movement.

Wait, but the rules say "conclude with camera perspective and movement". So "camera remains close-up and static" at the end.

Let me check the output format: must be <caption_output>...<caption_output>

Need to make sure it's concise. Let's shorten: A hand presses strings on a light-colored guitar, fingers moving up and down the fretboard rhythmically. The scene is split-screen with sheet music visible on the left. The camera stays close-up and static throughout.

Yes. That's concise, chronological, covers motion, appearance, spatial (split-screen, left), camera.
</think>

<caption_output>A hand with visible fingers presses strings on a light-colored guitar, moving up and down the fretboard in rhythmic motions. The scene is split-screen, with

The person's hands are moving discretely to play the stringed instrument (plucking/strumming), representing solid objects interacting with physical forces.

Background elements (sheet music, table) show no shifting or fluid motion; no fire, water, smoke, or wind present.


Several red apples, some sliced, rest on a wooden surface. Hands place a whole red apple on the board and use a knife to slice it into a tic-tac-toe pattern, creating evenly spaced vertical and horizontal cuts. The hands remain centered on the apple as they maneuver the knife, with the wooden surface providing the background. The camera maintains a consistent top-down perspective throughout.

Hands and knife moving to cut the apple. The apple is stationary until cut, then pieces move due to the cutting action.

No shifting background elements or fluid/environmental motion. The kitchen background in the initial shot and the wooden cutting board in the overhead shot are static. No fire, water, smoke, or wind observed.

The background features a static wooden wall with no shifting or fluid motion (fire, water, smoke, wind) observed.


RAW CAPTION: Got it, let's break down the video. First, the scene is a football game. There are two teams: one in dark uniforms (probably navy with red accents) and the other in white. The main action starts with the team in white on offense. They line up, the quarterback takes the snap, drops back, and then there's a play where the ball is thrown. The receivers try to catch it, but maybe it's intercepted or a tackle happens. Then the players from the dark team (defense) might be involved in a tackle or a sack. Let's check the frames: in frame 0, the quarterback is in the pocket, then he throws the ball, a player catches it (maybe), and then there's a tackle. Then the play ends with players down. The crowd and officials are in the background but not the main focus.

Wait, the user says to focus on motion and behavior in chronological order. Let's outline:

- Start: Offense (white jerseys) lines up, quarterback takes snap (frame 0).
- Then quarterback drops back, throws ball (frame 1-2).
- A receiver catches the ball (frame 2), but then a defender (dark jersey) tackles him (frame 3-4).
- The play ends with the ball carrier down (frame 4), and players from both teams are around, maybe the ref is there. The defense team (dark) is standing on the sideline, watching the play.

Wait, in the frames, the first frame shows the quarterback (white) in the pocket, then he throws, the ball is in the air, then a white jersey player catches it? No, maybe a tackle happens. Wait, frame 0: the play starts. The offense (white) is at the line of scrimmage, quarterback (number maybe 12?) takes the snap. Then he drops back, throws the ball. In frame 1, the ball is in the air. Frame 2: maybe a receiver is trying to catch, but a defender (dark) moves in. Frame 3: the ball carrier is tackled by multiple defenders. Frame 4: players are down, referees and other players are around.

Now, the main subjects: football players (offense and defense), referees. Number of players: offense (white) has several (like the QB, receivers), defense (dark) has around 10-15 in the scene. Appearances: dark jerseys (navy, red numbers), white jerseys (white, blue numbers). Spatial relationships: offensive players in the center (playing), defensive players near the sideline (watching the play as it happens). Then the play happens: QB throws, receiver gets it, then defender tackles, players go down.

Camera perspective: seems like a sideline camera, top-down or side angle? The video shows a wide shot of the field, so maybe a high angle, but the description says "camera perspective and movement". In the frames, the camera doesn't move much; it's a steady shot capturing the play from the sideline.

Now, structure the caption:

First, the initial setup: The football team in white jerseys lines up at the line of scrimmage, with the quarterback (in white) taking the snap. Then the quarterback drops back and throws the ball. The receiver (also in white) attempts to catch it but is tackled by a defender (in dark jersey). Multiple defenders converge, bringing the ball carrier to the ground. The defensive team (dark jerseys) then stands on the sideline, observing the aftermath. The camera remains static, capturing the play from a sideline perspective.

Check rules: chronological order, motion and behavior, appearance (white and dark jerseys), spatial (offensive center, defensive near sideline), conclude with camera (static, sideline).

Let me make it concise:

In the football game, the white-jerseyed offense lines up, with the quarterback taking the snap, dropping back, and throwing the ball. A receiver in white attempts to catch it but is tackled by a dark-jerseyed defender; multiple defenders converge and bring the ball carrier to the ground. The dark-jerseyed defensive team stands on the sideline, observing the play. The camera remains steady, capturing the action from a sideline angle.

Wait, check the numbers: the offensive team (white) has players like 8, 10, etc., but we don't need to mention specific numbers. The rule says "briefly describe their appearance and number (color, size, orientation)" but "number" here is not the player numbers, but maybe the count? Wait, the rule says "appearance and number (color, size, orientation)". So perhaps "the offensive team, dressed in white jerseys, with several players; the defensive team, in dark jerseys, with multiple players".

But the task says "briefly describe their appearance and number (color,

Discrete solid objects (football players in uniforms) are moving due to locomotion and collisions during gameplay. Players in the foreground and midground exhibit directional movement typical of football plays.

The background (football field lines, stands, and distant objects) remains stationary across frames with no uniform shifting. No fluid or wind-driven environmental motion is observed.


RAW CAPTION: Got it, let's tackle this. First, I need to watch the video and note the main actions. The video shows four people in a room. Let's check the sequence.

At the start, there are four people. One is holding a stick, maybe a cane or something. Then, they all move. Wait, the first frame: four people. One on the left is in dark clothes, then another in black, a third in dark top and jeans, and one in blue shirt. Then in the next frames, they move. Wait, the sequence:

Frame 0: Four people. Let's see their actions. One person on the right (with a cane) is raising their arm. Another person in the middle left is also raising. Then frame 1: they start moving. Frame 2: some are moving left, right. Then frame 3: the person in dark clothes (maybe left) runs towards the camera? Wait, the description says "two people in dark shirts and jeans" but maybe the exact numbers.

Wait, the key is to list the actions chronologically.

Looking at the video:

- Start: Four people. One person (left) in dark shirt and pants, another (center) in dark shirt and jeans, third (right) in dark top and jeans holding a cane, fourth (front right) in blue shirt. They're all moving.

Frame 0: All four are in motion. One (center left) is raising arm. One (right) has arm up. Then frame 1: the person in blue shirt is swinging a stick (cane) and moves to the right. Frame 2: the person in blue shirt exits right. The others move: the center person (black shirt) is moving left, the right person (dark top) moves towards the door, the left person (dark shirt) is moving left. Frame 3: the person in dark shirt (left) is still moving left, the center person (black) is now on the floor? Wait, frame 3: the person who was in the center is sitting on the floor. Wait, frame 0: four people. Frame 1: maybe one person is moving away. Frame 2: two people are moving towards the camera? No, the video description might have: in frame 3, one person is sitting on the floor.

Wait, let's break down each frame:

Frame 0: Four people. One (left) in dark shirt and pants, one (center) in black shirt, one (right) in dark top and jeans with cane, one (front right) in blue shirt. All are moving. The one on the right is raising their arm.

Frame 1: The person in blue shirt is now moving towards the camera (from front right to center). The person in dark top and jeans (right) is moving towards the door (right side). The center person (black shirt) is moving left. The left person (dark shirt) is moving towards the camera.

Frame 2: The person in blue shirt exits right. The left person (dark shirt) is now moving towards the camera, almost out of frame. The center person (black) is still moving left. The right person (dark top) is now near the door.

Frame 3: The person in dark shirt (left) is moving towards the camera. The center person (black) is now sitting on the floor (suddenly). The right person (dark top) is standing by the door.

Wait, maybe the key actions are: all four people are moving, then the center person (black shirt) trips and falls. Wait, no, frame 3: the person in dark shirt (left) is moving left, and the center person is sitting on the floor. Wait, maybe the sequence is:

0.0: Four people are in the room, moving. One person (left) in dark clothes, one (center) in black, one (right) in dark top and jeans holding a cane, one (front right) in blue shirt.

0.25: The person in blue shirt swings a cane (stick) and moves right. The person in dark top (right) raises arm. The person in black (center) raises arm.

0.5: The person in blue shirt is moving out of frame to the right. The person in dark top (right) moves towards the door. The person in black (center) is moving left. The person in dark shirt (left) is moving left.

0.75: The person in dark shirt (left) is moving left, the person in black (center) is now sitting on the floor. The person in dark top (right) is standing by the door.

Wait, in frame 3, the person in black (center) is sitting on the floor. So maybe the action is

Multiple people moving: running, throwing objects (balls), and one person falling. Discrete solid objects (people, balls) exhibit locomotion and collisions.

No shifting backgrounds observed; walls, ceiling lights, and door remain static. No fluid motion (fire, water, smoke, wind) present.


A hand unrolls a brown paper roll with red lobster patterns onto a dark, worn table, then places a black box with a white label onto the paper, adjusting its position. A white tape dispenser sits to the right of the paper. The camera remains stationary in a top-down view.

The hands manipulate solid objects: unrolling a fabric with crab patterns, placing a book on the fabric, and positioning a stapler. These actions involve discrete, solid objects moving due to explicit physical forces (hand movements).

The background (dark surface with marks) remains static with no uniform shifting or fluid environmental elements (fire, water, smoke, wind) present.

A man in a blue shirt and dark pants is moving his body and cleaning tool (sponge/cloth) to wipe a window. His motion includes bending, reaching, and scrubbing motions with deliberate locomotion.

The background (wall, window frame, interior structure) shows no shifting or movement. No fluid/environmental motion (fire, water, smoke, wind) is present; the scene is controlled indoor cleaning with static ambient conditions.


A man in a light-colored shirt and dark pants lies on his side in a sandy enclosure, gradually shifting his position and moving his arm. The enclosure is bordered by white railings, with spectators visible in the background stands. The camera remains stationary, observing the man’s slow repositioning within the arena.

A single person is visible in a sandpit; their position shifts slightly across frames, indicating subtle movement within the sand.

Background elements (railings, signage, trees) show no uniform shifting. No fire, water, smoke, or wind-driven motion observed.


A man with short dark hair lies on a bed with eyes closed, covered partially by a light blue sheet; two hands gently massage his head in a circular motion, moving from the temples toward the sides, while his head rests on a white pillow. The camera maintains a steady top-down perspective throughout.

A person lying on the bed is receiving a neck massage; the hands performing the massage move in discrete, intentional motions across the neck area, indicating explicit physical force application.

The background consists of a static bed with white sheets and walls; there is no shifting background or fluid/environmental motion (e.g., fire, water, wind).


A baby wearing a yellow shirt and brown shorts, barefoot, stands on a dark rug pushing a blue and yellow toy, then sits down while holding the toy’s handle, smiling as the camera captures the motion with slight shake.

The baby (a solid, distinct object) is actively moving: pushing the toy, kneeling, and shifting position while interacting with the blue and yellow toy.

The background elements (furniture, walls, floor) show no uniform shifting or fluid/environmental motion (e.g., no fire, water, smoke, or wind).


The video opens with a person wearing black headphones and a light blue shirt speaking into a microphone. It then cuts to another person in a light blue shirt with short hair speaking in front of a background with industrial equipment. Both individuals remain stationary throughout; the camera alternates between these two fixed shots with no movement.

Two human subjects (discrete solid objects) exhibit minor head/neck movements and speech-related motions due to muscle activity. These are localized movements consistent with locomotion and physical expression.

Both scenes feature static backgrounds (plain wall and office environment) with no fluid motion (water, fire, smoke, wind) or environmental distortion. Background elements remain fixed without uniform shifting.


A child in an orange sleeveless top and pink pants milks a large brown cow, then moves their hands upward along the cow's side. The child stands to the right of the cow, with a metal bucket positioned below. The camera follows the child’s motion with a slight shake.

Child (in orange shirt) is moving via locomotion and hand gestures to interact with the stationary cow.

Static background of gravel and rocks; no environmental motion (fire, water, wind) detected.


RAW CAPTION: Got it, let's break down the video frames. First, the video starts with a close-up of a person in a high-visibility yellow vest holding a dirt-covered clay vessel. The hands are careful, showing the object. Then it cuts to a close-up of dirt being sifted, maybe with a tool. Next, a hand wearing a glove is seen in a trench, probably an archaeological dig site, with the trench having layers and a white string line (maybe for measurement). Then, the person is using a brush or tool to clear dirt from the vessel, revealing it. The background has the trench, other people in the distance, but the focus is on the digging and cleaning.

Need to make a chronological paragraph. Let's check the rules: motion, behavior, appearance, spatial, camera perspective.

Frame 0: Close-up of hands with yellow vest holding clay vase covered in dirt. Person is handling the artifact.

Frame 1: Close-up of dirt being sifted, maybe a tool moving through soil.

Frame 2: A hand in a trench (dirt mound), the trench has layers, maybe the same site.

Frame 3: Hand with glove in trench, using tool to clean the vase, which is partially buried. The trench has string for reference.

Frame 4: Close-up of the vase being cleaned, showing the object more clearly.

Now, order of events: first, the vase is held (frame 0), then dirt being sifted (frame 1), then the trench with the vase in the dirt (frame 2), then the hand cleaning the vase (frame 3), then the cleaned vase (frame 4). Wait, the frames are sequential: [0], [1], [2], [3], [4]. So:

1. Close-up of hands holding a small, brown clay vessel covered in dirt; the person wears a high-visibility yellow vest.
2. Close-up of a tool sifting through loose, grayish-brown dirt.
3. A gloved hand in a dirt trench, with a white string line visible in the background, partially uncovering a similar clay vessel.
4. The gloved hand continues to brush dirt from the vessel, revealing more of its shape against the trench walls.
5. The vessel is now clearly visible, with its surface cleaned to show texture.

Wait, the frames are 0 to 4. Let's map each frame:

[0] - person holds vase (hands, yellow vest)
[1] - dirt being sifted (close-up)
[2] - dirt mound with a hole (maybe the vase is buried)
[3] - hand with glove in trench, excavating (trench with string)
[4] - the cleaned vase (now visible)

Wait, the sequence is: first, the vase is held (frame 0), then dirt is being sifted (frame 1), then a trench with a buried object (frame 2), then a hand in the trench clearing the object (frame 3), then the object being cleaned (frame 4). But the exact frames:

Frame 0: hands hold vase (yellow vest)
Frame 1: dirt being moved (sifted)
Frame 2: dirt pile with a hole (maybe the vase is in the hole)
Frame 3: hand in trench, using a tool to dig up the vase
Frame 4: the vase is now clean, held or placed in the trench.

Wait, no, the frames are:

[0] = person holds vase (hands, yellow vest)
[1] = close-up of dirt being sifted (soil particles moving)
[2] = close-up of a hole in the dirt (the vase is inside)
[3] = gloved hand in trench (trench has string lines) excavating the vase
[4] = the vase being cleaned (gloved hand brushing dirt off)

So chronological order:

- A person wearing a yellow high-visibility vest holds a small, brown clay vessel coated in dirt.
- The scene shifts to a close-up of loose grayish-brown dirt being sifted by a tool.
- Next, a hole in the dirt mound reveals a similar clay vessel partially buried.
- A gloved hand in a trench, marked by white string lines, carefully brushes dirt from the vessel.
- Finally, the vessel is shown with its surface cleaned, revealing its shape and texture.

Now, check the rules. Focus on motion and behavior, chronological. Appearance: person's vest color, vase color, dirt. Spatial: the trench with string lines, the vase being in the hole.

Camera perspective: first close-up, then close-up of dirt, then close-up of hole, then medium shot of hand in trench, then close-up of vase.

But the caption needs to be concise. Let's

Discrete solid objects moving: hands with tools (gloves, trowel) actively digging and displacing soil. The soil being moved is a solid material undergoing mechanical displacement.

No shifting backgrounds or fluid/environmental motion (fire, water, wind) detected. Background elements (mud, trench walls, ground) remain static throughout the frames.


A person in a striped apron uses a large cleaver to cut red meat on a white cutting board, slicing the meat into smaller pieces while repositioning the pieces with their hand; a plate of additional red meat sits to the right of the board on a white table, with the scene captured from a static top-down camera angle.

Discrete objects: knife (moving vertically/horizontally to cut meat) and meat pieces (being displaced and severed by the knife). Motion is caused by explicit physical forces (hand-driven chopping).

The background (kitchen wall, vent, table) is static with no shifting or environmental motion; no fire, water, or wind present.


RAW CAPTION: Got it, let's tackle this. First, the video shows a person throwing something. Let's break down the frames.

In frame 0, the person is in a throwing motion, arm extended. Frame 1, they're pulling back, preparing to throw. Frame 2, the arm is back, maybe after releasing? Wait, no, the action is chronological. Let's see:

The sequence: The person (female, white hoodie, dark pants) is in a backyard. She's holding an object, probably a frisbee or ball. She starts with arm extended forward (frame 0), then pulls back (frame 1), then extends again (frame 2), then throws (frame 3), and maybe follows through (frame 4). Wait, the frames show her motion: first throwing, then pulling back, then preparing, then throwing again? Wait, the video is a sequence of actions.

Looking at the frames: 0.0s - she's in the middle of a throw (arm forward), 0.3s she's pulling back, 0.6s arm up, 0.9s arm back, 1.2s arm forward again? Wait, no, the frames show the person's motion. Let's track each frame.

Frame 0: Person with right arm extended forward, left arm bent. Then frame 1: left arm back, right arm up? Wait, no, maybe it's the throwing motion cycle. The person is throwing a frisbee or something. So the motion is: wind up, throw, follow through.

The main subject is one person. Appearance: female, white hoodie, dark pants. Action: throws an object (probably a frisbee) repeatedly. The background is a fenced backyard with trees, grass, a wooden structure, houses.

Chronological order: The person starts by extending arm forward (throwing), then pulls back, then throws again. Wait, the frames show:

0.0s: arm extended (throwing)
0.3s: arm back (wind up)
0.6s: arm up (releasing)
0.9s: arm forward again (another throw)
1.2s: arm back (wind up)
1.5s: arm extended (throwing again)

Wait, no, the actual video frames provided:

[0.0] she's throwing (arm forward)
[0.3] she's pulling back (arm back)
[0.6] she's in the middle of the throw (arm up)
[0.9] she's following through (arm forward)
[1.2] she's pulling back again (arm back)
[1.5] she's throwing again (arm forward)

Wait, but the user provided 0.0 to 1.5 seconds, with 5 frames? Let's list each frame:

Frame 0 (0.0s): Person with right arm extended forward, left arm bent (throwing motion)
Frame 1 (0.3s): Person pulling back, right arm behind body, left arm forward
Frame 2 (0.6s): Person with right arm up, left arm bent
Frame 3 (0.9s): Person with right arm extended forward (after throwing)
Frame 4 (1.2s): Person pulling back, right arm behind body
Frame 5 (1.5s): Person with right arm extended forward (throwing again)

Wait, but the user's example has the first frame as [0.0] with person throwing, then [0.3] pulling back, [0.6] arms in position, [0.9] throwing, [1.2] pulling back, [1.5] throwing. So the action is repetitive: wind up (pull back), throw, follow through.

So the chronological description: A person in a white hoodie and dark pants repeatedly throws an object, starting with arms extended (throwing), then pulling back, then extending forward again, with each throw motion occurring sequentially.

Now, spatial relationships: The person is in a backyard, near a fence, with trees and grass in the background. The wooden structure is to the left.

Camera perspective: The video is shot from a fixed angle, probably a medium shot, not moving (since the camera doesn't shift; it's a steady shot). The camera is at eye level, showing the person from the side.

Background: Minimal description. The backyard has grass, a fence, trees, houses. But according to rule e, keep background minimal unless essential. So mention if necessary.

The key is to focus on the person's motion, chronological.

So putting it all together:

"A person wearing a white hoodie and dark pants stands in a grassy backyard near a fence, repeatedly throwing an object. Initially, they extend their right arm forward

A person is performing discrete actions: swinging a bat-like object, moving their arms and body in controlled motions consistent with physical exertion (e.g., baseball swing).

Background elements (fence, tree, grass) show no uniform shifting or fluid motion (e.g., fire, water, wind). Static environment with no dominant ambient phenomena.


A barefoot person wearing a blue plaid shirt and jeans walks into the frame from the right, approaches a red object and black container on the grass near a wooden post, bends down to pick up a white pipe, then sits on the grass facing the camera. The background includes a wooden fence, a house with stacked items, and a tree. The camera remains stationary throughout.

A person enters the frame, walks, crouches, picks up an object from the ground, and sits down. These are discrete, solid-object movements.

Static background elements (house, fence, tree, grass) show no uniform shifting or fluid motion (fire, water, smoke, wind).


Two individuals in a gym: one wearing a white T-shirt, black pants, and black cap swings dumbbells, lowering them in a repetitive motion; the other, in a red jacket, white cap, and black pants with white stripes, holds a large black tire steady. The left person continues arm movements, while the right person maintains grip on the tire. The scene occurs on red flooring with gym equipment visible in the background. The camera remains stationary.

Two people and a tire are present. The person in white (left) performs repetitive swinging motions with a sledgehammer, impacting the stationary tire. The person in red (right) stands mostly still, occasionally shifting position to maintain the tire's placement.

The gym background (walls, American flag, equipment) remains static with no fluid motion (fire, water, smoke) or environmental wind effects. Background elements show no uniform shifting.


A person in a black shirt, cap, and gloves cleans solar panels on a roof using a long pole. They then move indoors, cleaning a large window with a tool while standing near the window and facing outward. The camera transitions from an exterior view of the roof to an interior view of the room with windows.

A person cleaning windows moves their arms and body to operate cleaning tools; another person (woman) interacts and moves during conversation inside the house. Both exhibit locomotion and object manipulation.

Background elements (house, trees, sky) remain static throughout the clip; no fluid/environmental motion (fire, water, wind) observed. Background does not shift uniformly.


A brown-capped mushroom with a red-yellow stem grows among dry leaves and soil. Adult hands enter the frame, grasp the mushroom, lift it, and peel back the cap to expose the inner surface. The hands hold the mushroom, showcasing its cap and stem. The camera perspective shifts slightly with the hand movements during the action.

A hand (discrete object) interacts with an acorn (discrete object), manipulating and opening it. The hand moves deliberately, applying physical force to the acorn, showing clear solid-object motion.

Background elements (leaves, dirt, static objects) show no uniform shifting or fluid environmental motion (fire, water, smoke, wind). Background remains relatively stable with no dominant ambient environmental motion.


A person wearing a white sleeveless shirt, gray shorts, and black shoes stands on a grassy field, initially raising their right leg in a kicking motion. They then extend both arms forward, step forward, and shift their body to the right. A black backpack lies on the grass to the left of the person, with parked cars and trees visible in the background. The camera remains static with minimal movement.

A single person is performing leg extension and arm movement, indicating intentional locomotion.

Background elements (trees, parked cars, grass) show no uniform shifting or fluid motion. Tree sway is minimal and not dominant.


RAW CAPTION: Got it, let's break down the video. First, the video shows a baking tray with small dough balls. The text says to bake for 5 minutes at 250° or until they pop out. Then, a hand picks up a dough ball, showing the inside. Next, there's a glass with cookies. Let's make sure to follow the rules.

Start with the tray: metal baking tray with 20 small round white dough balls. Then the hand reaches in, picks one up, revealing a golden-brown interior. Then the scene changes to a glass filled with round, golden-brown baked cookies. Need to mention the order: first tray, hand action, then the glass.

Check the chronology: [0.0] tray, [1.4] tray (maybe a slight change, but same), [2.5] hand adding? Wait, the second frame shows the hand putting a dough ball? Wait, the video: frame 0-1: tray with dough balls. Frame 2: hand placing a dough ball. Wait, the first frame says "Levar ao forno..." but the video shows the tray with dough balls. Wait, the video starts with tray with dough balls, then a hand adds a dough ball? Wait, no. Let's look at the frames:

[0.0] Trays with dough balls (metal, small white round balls). [1.4] Same tray. [2.5] Hand placing a dough ball (so adding a ball). [3.6] Hand holding a ball, showing interior. [4.7] Glass with cookies.

Wait, the instructions say to describe motion and behavior. Let's see:

Initial: tray with many small white dough balls arranged in rows. Then a hand places another dough ball (so adding to the tray). Then the hand picks up a dough ball, revealing the inside (golden-brown). Then cuts to a glass filled with round, golden-brown cookies.

Wait, the text in the video is about baking, so the dough is being baked, then shown as cookies.

Wait, the video starts with the tray with dough balls (before baking), then the hand is adding a ball (maybe checking or placing), then the hand holds a ball to show the interior (after baking, so the dough is now a cookie). Wait, the step where the hand breaks it open is showing the interior, which is the cookie inside. Then the glass shows the baked cookies.

So chronological:

1. A metal baking tray holds numerous small, round, white dough balls arranged in a grid.
2. A hand places an additional dough ball onto the tray.
3. The hand picks up one dough ball, revealing a golden-brown interior.
4. The scene shifts to a glass filled with round, golden-brown baked cookies.

Check for rules: main subjects (dough balls, hand, cookies). Motion: placing, picking up, shifting scene.

Appearance: dough balls white, round, small. Cookies golden-brown.

Spatial: hand interacting with tray, then glass.

Camera: top-down view for the tray, then close-up on hand, then top-down on glass.

Need to mention the number? The dough balls are many, but the rules say "briefly describe appearance and number" - so "numerous small round white dough balls".

Let's structure the caption:

The video opens with a metal baking tray containing numerous small round white dough balls arranged in a grid. A hand then places an additional dough ball onto the tray, followed by picking up one dough ball to reveal a golden-brown interior. The scene transitions to a glass filled with round golden-brown baked cookies. The camera maintains a top-down perspective throughout, shifting to a close-up during the hand’s interaction with the dough balls.

Wait, check rules: exclude text recognition. The text is part of the video, but we shouldn't mention it. So no "Levar ao forno...", just the visual elements.

Check the rules again:

a) Focus on motion and behavior in chronological order.

So the order is:

- Tray with dough balls (static, then hand adds one, then hand breaks to show inside, then glass of cookies).

Yes.

Now, concise paragraph.

"Numerous small round white dough balls are arranged on a metal baking tray. A hand places another dough ball onto the tray, then picks up one to reveal a golden-brown interior. The scene cuts to a glass filled with round golden-brown baked cookies. The camera provides a top-down view of the tray, a close-up of the hand’s action, and a top-down view of the glass."

Wait, check if "numerous" is needed. The video shows the tray with many, so "numerous" or "multiple". Let's use "multiple".

Also, the hand action: placing a dough ball (so the hand

A hand manipulates solid dough balls (discrete objects), lifting and rotating one to reveal its interior. The motion is caused by explicit physical interaction (hand movement).

No shifting backgrounds or fluid/environmental motion (fire, water, smoke, wind) observed. Background elements (kitchen counter, tray) remain static throughout.


A man wearing a white tank top, black shorts, and yellow sneakers performs an exercise on a blue mat with a large white exercise ball. He begins in a plank-like position, leaning forward with his hands on the ball and legs extended behind him. He then pushes his lower body forward, shifting his weight while maintaining contact with the ball. The camera remains static, capturing the motion from a front-facing perspective against a backdrop of beige and brown walls.

A person (wearing white shirt and black shorts) is actively moving on a yoga mat while interacting with a stationary exercise ball. The person's body shifts in controlled motions (e.g., bending torso, adjusting weight distribution), indicating intentional physical exertion.

The background consists of static wall panels and floor with no shifting, fluid, or environmental motion (e.g., no fire, water, wind). Walls and floor remain uniformly fixed throughout the clip.


A person in a red uniform and blue gloves pours liquid from a container into a red bucket, then moves to a metal shelf holding multiple white rectangular containers arranged in rows on a grid, and returns to the pouring area. The camera follows the person's movements with slight shifts in focus.

A person in a red robe manipulates white rectangular containers on a counter, lifting and repositioning them with manual motion.

The tiled walls and counter in the background remain static across frames; no significant fluid, gaseous, or wind-driven environmental motion is observed.

Background elements (trees, ground) show no significant shifting or fluid motion; no fire, water, smoke, or wind is present.


A hand holds a white curved paper, another hand cuts its edge with scissors; the paper is flipped to reveal a yellow and multicolored dotted side, then folded into a shape with yellow cutouts. The camera maintains a close-up, top-down view throughout.

Hands and paper are discrete solid objects moving due to manual manipulation (cutting, folding, and handling the paper).

Static gray background (table surface) with no shifting or environmental motion; no fire, water, smoke, or wind present.


Two individuals sit side by side; the person on the left has dark hair and wears a dark jacket over a white shirt, while the person on the right has light brown hair and a white t-shirt. The left individual turns their head toward the right, then looks forward, while the right individual looks down, then lifts their gaze. The camera remains close, slightly shaky, focusing on their upper bodies against a dark background.

Two people (a man and a woman) exhibit subtle head movements (turning, looking at each other, shifting gaze).

The background (vertical lines) is static and there is no fluid/environmental motion (fire, water, smoke, wind).


Two men stand side by side; the left man wears a pink turban and light pink striped shirt while holding a phone, the right man wears a blue hoodie and holds a phone to his ear. The right man lowers the phone and looks downward, then both men turn to face the camera. The camera remains static with no movement throughout.

Two people (solid objects) are present; the individual in blue moves their hand from a phone call position to holding the phone, while the individual in pink remains relatively stationary but holds a phone. Their motions are discrete, self-driven actions (e.g., phone handling, slight body shifts).

The background consists of static walls with mounted signs; no shifting background elements or fluid/environmental motion (fire, water, smoke, wind) observed.


A person in a black sleeveless top and gray shorts, barefoot, performs a dance sequence in a bright studio. They start in a squat with the right hand near the head, then lift the right leg high to the side while balancing on the left leg, followed by lowering the leg and returning to the squat position. This motion repeats. The background includes mirrored walls and silhouette artwork, with red and blue cylindrical objects visible. The camera remains static, capturing the entire sequence from a fixed angle.

A single person (discrete solid object) is performing locomotive movements: transitioning between squatting and standing positions while lifting one leg. The motion is driven by intentional physical exertion (e.g., exercise/dance).

The background (white walls, mirrors, blackboard, and fixed objects) remains static throughout the video. No fluid, fire, water, smoke, or wind effects are present to qualify as ambient environmental motion.


A person wearing a camouflage-patterned jacket and dark pants stands in murky water near rocky banks and dense foliage. They step onto a horizontal log, balancing briefly, then move rightward into the water, creating ripples as they walk. The camera follows the person’s movement from behind with slight handheld shake.

A person in a camouflage jacket is stepping from one rock to another in the river, moving by locomotion.

The river water is flowing (ambient environmental motion), but the background (trees and rocks) is stationary. The dominant motion is the person stepping on rocks.
