RAW CAPTION: Got it, let's break this down. The video shows a woman in a striped shirt and dark pants moving in a room. First, she's standing near the chairs, then runs to the right, exits the frame, comes back, and then runs again. Need to track her movements chronologically.

Start: She's in the room with orange chairs, two doors. She moves to the right (out of frame), then re-enters from the left, runs towards the camera, maybe? Wait, the sequence is: [0.0] she's there, [1.4] runs right, [2.5] back to the left, [3.6] she's on the left side moving towards the right again, then [4.7] she's near the chairs, then the scene changes to a different person (but rule says exclude named characters, so focus on main subject which is the first woman).

Wait, the video has two parts: first the woman moving, then a cut to another scene. But the task says "main subjects (people/animals/objects) in chronological order". So first the woman in striped shirt, then the next scene is a different person. Wait, the video description: the first part is the woman, then at [5.0] it cuts to another person. But the problem says "the provided video", so we need to include all.

Wait, the video clips: the first part is the woman in the waiting room, then the second clip is another person (a man with a white coat, maybe a doctor). But according to the rules, we need to describe motion chronologically.

Let's check the timestamps:

[0.0] woman standing in waiting room with orange chairs, two doors.

[1.4] she runs to the right (out of frame)

[2.5] she's not there, then she re-enters from the left, runs towards the chairs.

[3.6] she's moving to the right, then runs back.

[4.7] she's in the middle, maybe.

Wait, the exact frames:

Frame 0: woman in striped shirt and dark pants standing near chairs.

Frame 1: she runs to the right (out of frame)

Frame 2: she's not visible, then frame 3: she's back, walking towards the chairs.

Frame 4: she's moving from left to right, approaching the camera.

Frame 5: then the scene cuts to a different person (the man in white coat).

Wait, the video sequence: first part is the woman in the waiting room, then at frame 5 (which is [4.7] maybe?) it changes. Wait the description says:

[0.0] woman in waiting room

[1.4] she runs right

[2.5] she's out, but then frame 3: she's moving back

Wait, the user provided the video description with the timestamps. Let's list the key frames:

- 0.0: woman standing in room with orange chairs, two wooden doors, wall with posters.

- 1.4: woman runs to the right, exits frame.

- 2.5: she is now to the left of frame, walking towards chairs.

- 3.6: she moves across the frame from left to right, near the chairs.

- 4.7: she continues moving right.

Then at the next frame (the fifth one, which is the next clip), it shows another person (a man in white coat holding a towel), but according to the rules, we need to include all motion.

Wait, but the problem says "the provided video" which includes both clips. So the video is two parts: first the woman in the waiting room moving, then a cut to another scene (the man). So the chronological order is: first the woman's movements, then the man's action.

But according to the rules, we need to describe the motion of the main subjects in chronological order. The first main subject is the woman, then the second main subject is the man.

Let's check the rules:

a) Focus primarily on the motion and behavior of main subjects (people/animals/objects) in chronological order.

So first, the woman moves: stands, runs right, then comes back, moves across the room. Then the scene cuts to another person (the man with white coat), who is holding something and looking at the camera.

But we need to describe all.

Now, the appearance: woman has long hair, striped shirt (white and dark), dark pants. The man has short hair, white coat, holding a towel.

Spatial relationships: in the waiting room, the woman moves between the chairs and doors. The man is in a different setting (maybe the same room but different area?).

Wait, the first scene:

A woman (solid object) is walking across the room, moving from left to right and then back.

The background (wall, doors, chairs) is static and does not shift uniformly. There is no fluid or wind motion. A brief glitch (hand) occurs but is not dominant.


A person in a black suit and white dress shirt adjusts a red and blue striped bow tie with both hands, pulling it into place around their neck and securing it. The background features window blinds. The camera remains stationary, focused on the upper torso.

A person's hands and torso are moving to adjust a bow tie, representing discrete solid object motion.

Background consists of static window blinds with no shifting or fluid motion; no fire, water, or smoke observed.


A girl in a red polka-dot dress with a headband washes a brown dog in a large metal tub filled with soapy water, scrubbing its fur with her hands before using an orange brush to groom it. The dog remains submerged in the tub as the girl moves the brush over its body. The camera maintains a static frontal view throughout, focusing on the girl and the dog with minimal background details visible.

The girl and the cat are the discrete solid objects moving. The girl uses her hands to wash the cat, causing the cat to move within the sink and water to splash.

The background (window and wall) is static with no uniform shifting. The water in the sink is being actively manipulated by the girl, so it is not ambient fluid motion; it is part of the discrete object interaction.


A man in a gray t-shirt, dark cap, and earphones interacts with a large touchscreen monitor on an exercise bike, adjusting the screen with his hands. The camera shifts slightly to capture his movements as he remains seated.

The camera maintains a close-up perspective with slight movement throughout.

A person's hands interact with a machine (opening/closing compartments, inserting paper, pressing controls), demonstrating discrete solid object motion via physical forces (pushing, pulling, grasping).

The background elements (walls, machine structure) show no uniform shifting or fluid environmental motion (fire, water, wind). Static elements remain consistent across frames.


A man in a dark suit and tie sits at a wooden table, moving his hands across papers and a water bottle. Behind him, several individuals in suits are seated. Throughout the sequence, the man adjusts documents on the table. The camera remains static in a medium shot perspective.

A man's hands are moving (signing a document), representing discrete solid objects in motion due to explicit physical action (locomotion of hands).

Static background elements (chairs, people, room walls) show no uniform shifting or fluid motion; no fire, water, smoke, or wind visible.

The child in green pants and pink shorts steps back from the hug, and the child in white shirt and pink shorts turns toward the seated toddler. Background includes a pink chair and a playpen. The camera remains stationary.

Three children are moving: one in green pajamas walks away from the hug, another in pink shifts position while sitting, and the third in white interacts with the others. Their movements involve walking, sitting, and turning, all driven by physical locomotion.

The background elements (wall, wooden floor, baby gate) remain stationary with no uniform shifting. No fluid motion (fire, water, smoke) or environmental forces (wind) are visible.


A baby in a red floral-patterned outfit interacts with an adult wearing light-colored clothing; the baby moves their head and body, turning toward the adult whose hand is visible near them. The camera remains close and shaky, capturing their interaction with minimal background detail. Overall perspective is handheld, slightly unstable, focusing on the subjects' movements.

Two babies and a hand (adult) are moving: the baby on the left moves its head and body, the baby on the right moves its head and body, and the hand occasionally appears moving.

The background (red fabric) does not shift uniformly and there is no fluid/environmental motion (fire, water, smoke, wind).


A person in a dark swimsuit floats on their back in a swimming pool, drifting slowly along the lane. The blue and white lane dividers are visible in the background. The camera maintains a top-down perspective, capturing the person's gentle motion through the water.

A single swimmer in a swimsuit moving through the water via coordinated arm strokes and leg kicks, demonstrating discrete locomotion.

The pool walls and lane divider (blue/white line) are stationary, with no uniform background shift. Water movement is caused by the swimmer's motion, not ambient fluid dynamics.


A person in dark clothing carries a wooden piece toward the back of a brown wooden box structure, positioning it to attach L clips, with the camera maintaining a static viewpoint focused on the box and the person's movement.

The horse stands near a wooden structure and fence with sparse background elements. The camera maintains a static perspective throughout.

A person in a yellow jacket and a light-colored horse exhibit discrete, solid motion: the person makes minor adjustments while interacting with the horse, and the horse remains largely stationary with subtle head movements.

The background features a stationary barn structure and ground elements with no significant shifting or fluid motion (fire, water, smoke, or wind).


A person in a checkered shirt and white vest handles sliced bananas on a green tray, then lifts one banana while others observe from the market stall; the camera pans to follow the person’s actions with slight movement.

People (e.g., the individual in the striped shirt) manipulate mangoes on a green tray, with visible motion from slicing and transferring fruit.

Background elements (trees, structures, distant people) show no uniform shifting or fluid motion; no fire, water, or wind dominating the scene.


RAW CAPTION: Okay, let's tackle this video caption request. First, I need to understand the user's requirements. They want a concise, chronological paragraph describing the video, following specific rules.

Looking at the video description provided, there are several frames. The main subject seems to be a person in a red outfit with stripes, dancing. There's a backdrop with a red banner and other people around.

Rule a says focus on motion and behavior in chronological order. So I need to list the actions step by step. The first frame shows the person on stage, then moving, maybe spinning? The person is wearing a red jacket and striped pants. Other people are in the background, maybe band members.

Rule b: mention appearance and number. The main person is blonde, red jacket, striped pants. Others in the background, maybe two people visible in some frames.

Rule c: spatial relationships. The main person is in front, others behind. The banner is behind them.

Rule d: camera perspective. The camera might be moving, maybe panning or zooming. The description says the camera shows different angles, so maybe it's a slight shake or pan left.

Rule e: minimal background unless essential. The banner is part of the background, but maybe just mention it's colorful with a red banner.

Rule f: exclude text recognition. So don't mention "JERUSALEM" or anything on the banner.

Need to structure the caption in chronological order. Start with the main person on stage, then their movements, interactions with others, and camera movement.

Check the output format: must be in <caption_output> tags. No markdown. Just the paragraph.

Wait, the example in the problem statement shows that the caption should be a paragraph inside the tags. So first, describe the main subject's actions in order, then camera movement.

Let me outline:

- Person in red jacket and striped pants dances energetically.
- Moves from center to left, then back, arms raised, spinning.
- Other individuals in background (band members) playing instruments.
- Camera follows main person, zooming slightly and panning left.
- Background is colorful, but keep it minimal.

Need to check if the description mentions a drummer. Yes, in frame 0, there's a drum set. Maybe mention the drummer in the background.

Wait, the problem says exclude named characters, so no mentioning specific people, just their roles as band members.

Wait, the rules say "briefly describe their appearance and number (color, size, orientation)" so maybe "a drummer in a green outfit" but since it's "exclude named characters", but appearance is allowed.

But the rule says "exclude text recognition, named characters, or stylistic analysis". So appearance like color is okay. So in the background, there are band members: one in green, one in white, etc.

Wait, the video description mentions:

First frame: person with blonde hair in red jacket, striped pants, dancing. Behind: banner with "JERUSALEM", a drummer (maybe), and other people.

Wait, the user's video description has frames with a person on stage, then zooming in on the person, then rotating, etc.

The key points:

- Main subject: person in red jacket, striped pants, blonde hair, dancing. Actions: raises arms, spins, moves across stage.

- Background: colorful backdrop, red banner with text (but exclude text recognition), other band members (drummer, others).

- Camera movement: zooms in, follows the person, slight shake.

Need to structure chronologically:

Start with the person dancing energetically on stage, moving arms and body. Then the camera zooms in as they spin, then moves around them, showing other band members in the background (drummer, others). The camera pans left slightly as the person moves.

Wait, the user's video description shows the first frame as a wide shot, then zooming in on the person, then panning.

But according to the problem statement, we need to follow the frames chronologically.

Looking at the frames:

[0.0] Wide shot: person on stage with banner, drummer in background.

[1.4] Zoom in on the person, still dancing.

[2.5] Person continues dancing, maybe spinning.

[3.6] Person spins, moving.

[4.7] Person back to center, others visible.

So the chronological order is the person starts dancing, moves around, spins, and the camera follows their movements.

So the caption should start with the person dancing on stage, then moving, spinning, other band members in the background, camera following with slight movements.

Let me draft:

A person in a red jacket and striped pants dances energetically on stage, raising arms and spinning. The camera zooms in slightly as they move, revealing other band members in the background: a drummer with a green outfit

The central figure in red attire performs dynamic locomotion (dancing, arm movements, torso shifts) while two background figures also exhibit intentional movement. All motion is tracked as discrete solid object behavior driven by physical forces (e.g., muscle contractions for dancing).

Background elements (painted backdrop, banner, structural patterns) show no uniform shifting or fluid motion (fire, water, smoke, wind); all background features remain stationary relative to the scene.


A hand with a silver wristwatch featuring a blue face and white strap manipulates a white object secured by a black strap, adjusting the strap and repositioning the object. The camera maintains a close-up perspective focused on the hand and object throughout.

A hand is manipulating a black strap attached to a white object, with movements consistent with adjusting or fastening the strap.

The background consists of a static white structure with a black strap; no shifting backgrounds, fire, water, smoke, or wind are observed.


A man wearing a white shirt, dark jeans, and a brown hat sits on a large light-colored rock, using a tool in his right hand. He shifts his position slightly, moving his hand to adjust the tool. The scene is set in an open grassy area with trees, but the camera remains stationary throughout.

A person (wearing white shirt and red hat) is standing on a large rock, making small hand movements and postural adjustments while appearing to work with a tool. The person's motion is deliberate and localized to their upper body.

Background trees and grass are static; no fire, water, smoke, or significant wind motion observed. Background elements show no uniform shifting.


A person in dark clothing leans forward to operate a brightly lit lathe, adjusting the workpiece with both hands. Their hands shift between manipulating the workpiece and the machine's controls, moving slightly to the left as they focus on the illuminated area. The camera perspective transitions from a side view to a closer angle, highlighting the hands and machine components while the background remains indistinct.

A person's hands and arms are actively moving, manipulating objects (likely a workpiece and tool) on a table under a lamp, indicating explicit physical interaction.

No significant shifting of static background elements (walls, furniture) observed. No fluid or gaseous environmental motion (fire, water, smoke, wind) present.


RAW CAPTION: Got it, let's tackle this. First, the video shows a group of dancers. Let's list the sequence.

Starting with frame 0: There are multiple dancers. Let's count: maybe 5? Two women in black leotards with white tights, one in a white top and black pants. They're on stage, dark background. Their movements: arms raised, one woman leaping.

Frame 1: The dancers are moving, arms extended. Positions change—some to the left, right. One woman in black leotard does a leap, arms out.

Frame 2: More dynamic. A woman jumps with arms up, others move around. One in white shirt, black pants, maybe a man? Dancers are spread out, moving in sync.

Frame 3: They continue, some are in mid-air. The dancer in black leotard is central, others move around. Arm positions vary, some bent, some extended.

Frame 4: Dancers are in different positions. One woman steps forward, arms out. Others are behind, moving. The group's formation changes.

Frame 5: Dancers hold hands, move forward. The central dancer (black leotard) is leading, others follow. They're walking towards the front.

Now, check the rules. Focus on motion, chronological. Describe appearance: number, color. Spatial relationships: e.g., "one dancer in black leotard leaps to the left". Background is dark, minimal. Camera: probably fixed, since it's a stage performance, no mention of camera movement. Wait, the problem says "conclude with camera perspective and movement". The video is a stage performance, so camera is likely static, maybe a slight pan or fixed. But the frames don't show camera movement; the action is on stage.

So structure: start with first frame, then each frame's key actions, order, describe appearance (number, color, orientation), spatial, then camera.

Let's outline:

- Multiple dancers: 4 or 5? Let's count. Frame 0: at least 5. Some in black leotards (women), some in white tops (men? or other). Let's say 3 women in black leotards, 2 men in white tops? Wait, frame 0: two women in black, one man in white (right side), another in white left? Maybe. But the exact count might not be necessary. Rule b: briefly describe appearance and number. So "a group of dancers, including several in black leotards and white tops, perform on a dark stage."

Chronological order:

0.0s: Dancers begin with arms raised, one leaps high.

0.3s: Dancers move, arms extended, some leap.

0.6s: Dancers shift positions, mid-air leaps.

1.0s: Dancers move in sync, varied arm positions.

1.3s: Dancers walk forward, one leads, others follow.

Wait, no, the frames are [0.0], [0.3], [0.6], etc. Let's check the frames:

[0.0] - 4 dancers: two women (black leotards), two men (white tops, black pants). One woman leaps, arms up. Others are in different positions.

[0.3] - 4 dancers: same, moving. One woman in black leotard jumps, arms out. Others step.

[0.6] - Dancers leap, one in black is central, others around.

[1.0] - Dancers are in different positions, maybe some are behind, moving.

[1.3] - Dancers walk, holding hands.

Now, compile:

A group of dancers, including multiple in black leotards and white tops, perform on a dark stage. Initially, they raise their arms; a dancer in a black leotard leaps high with arms extended. Then, they shift positions, moving in synchronized leaps and turns. As the sequence progresses, some dancers step forward while others remain in the background, forming various formations. Finally, they walk forward in a line, hands linked. The camera remains stationary, capturing the full stage from a frontal perspective.

Wait, check rule g: exclude text recognition, named characters, stylistic analysis. So no mention of style. Also, rule e: background minimal. The background is dark, so "dark stage" is okay.

Check rule a: motion and behavior in chronological order. Yes.

Rule b: appearance and number. "multiple in black leotards and white tops" (so 2-3 black, 2-3 white). Number: "a group of dancers"—okay.

Spatial: "a dancer in black leaps high" (position relative to others?), but maybe not necessary. Maybe "the central dancer in

Multiple dancers (solid, discrete objects) perform synchronized ballet movements including leaps, spins, and coordinated formations. Their motion is tracked through distinct bounding boxes and driven by physical forces (locomotion, gravity, balance).

The background is a solid black stage with no visible environmental elements (fire, water, smoke, wind) or shifting background features. Background elements remain static throughout.

The background consists of a static tiled wall with no shifting or environmental fluid motion (fire, water, smoke, wind).


RAW CAPTION: Got it, let's break down the video. First, the scene is a park with a big tree. In the initial frames, there's a person climbing the tree. Let's check the details. The person is wearing a dark shirt and has long hair, maybe red? Wait, the video starts with a person partially hidden in the tree. Then they move up. Let's track the motion: the person is climbing the tree, moving from lower branches to higher up. The tree has a thick trunk, branches, and the background has a grassy area with picnic tables and a red structure maybe.

Now, the main subject is a person. They start at the lower part of the tree, climb up, and by frame 4-5, they're higher up, maybe halfway. Their appearance: dark top, light pants? Wait, the video shows a person with a pink headband maybe? Wait, the description says "person wearing a dark shirt" and "long hair." Let's focus on chronological order.

Frame 0: person partially in the tree. Frame 1: starts moving up. Frame 2: ascending. Frame 3: higher. Frame 4: continuing up. Frame 5: reaching a higher branch. So the motion is climbing the tree upward.

Spatial relationships: the person is on the right side of the tree. Background has grass, picnic tables, other trees. But according to the rules, keep background minimal.

Camera perspective: the camera is stationary, maybe a slight angle. Wait, the video starts with the tree in the foreground, camera might be fixed.

So the caption needs to be concise. Start with the person climbing. Mention their movement over time.

Let me structure it:

A person with long hair and a dark shirt climbs a large tree, moving upward from the lower branches to a higher branch. The camera remains stationary, capturing the action from a fixed position in front of the tree.

Wait, check the rules: focus on motion and behavior, chronological. So first frame: person starts climbing. Then moves up.

Also, number of subjects: one person.

Appearance: dark shirt, long hair (maybe pinkish, but not sure, but rules say mention if relevant. The problem says "briefly describe their appearance and number (color, size, orientation). So color: dark shirt, long hair. Size: presumably adult. Orientation: climbing the tree.

Spatial relationships: the person is on the right side of the tree.

Background: minimal, so just mention if necessary. But the rules say "keep background descriptions minimal unless essential for understanding motion." So maybe not needed.

Camera perspective: stationary, fixed.

So putting it all together:

A person with long hair and a dark shirt climbs a large tree, moving upward from the lower branches to a higher branch. The camera remains stationary, capturing the action from a fixed position.

Wait, let's check each rule:

a) Motion and behavior in chronological order: climbing upward. Yes.

b) Appearance and number: one person, dark shirt, long hair. Yes.

c) Spatial relationships: person on the tree, but maybe not necessary. The tree is central, so maybe not needed.

d) Camera: stationary, fixed.

e) Background minimal: yes, since it's a park, but we don't need to describe the picnic tables etc.

f) Exclude text, names: yes.

So the caption should be:

A person with long hair and a dark shirt climbs a large tree, ascending from the lower branches to a higher position. The camera remains stationary, capturing the motion from a fixed angle.

Wait, the video shows the person moving up, so chronological: starts at lower, moves up.

Let me check the frames: frame 0: person in tree, frame 1: starts climbing, frame 2: higher, frame 3: higher, frame 4: moving up, frame 5: higher. So it's a continuous climb.

Another thing: the person is on the right side of the tree. Maybe mention "positioned on the right side" but maybe not necessary.

Wait, the rules say "briefly describe their appearance and number (color, size, orientation)". So orientation: climbing, so maybe "climbing upward".

So final draft:

A person with long hair and a dark shirt climbs a large tree, moving upward from the lower branches to a higher branch. The camera remains stationary, capturing the action from a fixed position.

Yes, that's concise, chronological, mentions appearance, motion, camera.

Wait, does "dark shirt" need to be more specific? Maybe "dark top". But "dark shirt" is okay.

Also, check if the person has any other distinguishing features. The video might

A person is climbing a tree, moving upward through the frame.

Background trees show minimal wind sway but not dominant; no fire, water, or smoke present.


A hand holds a dark, irregular object near a girl with light brown hair, moving it closer to her face as she looks at it. The hand then shifts the object towards the second girl, who observes it. Both girls are positioned close to the camera, which maintains a close-up perspective with slight movement throughout.

Two individuals are present; one manipulates a chocolate-like object (hand movement towards mouth, object held up), and both show facial motion (e.g., mouth movements).

No shifting background elements or fluid/environmental motion (fire, water, wind) observed; background appears static.


A man in a dark jacket and light blue jeans bends over a white mailbox on a snowy yard, opening it with his right hand while holding a cane in his left. He inspects the mailbox, then closes it and turns to walk away from the post. The background features snow-covered ground and a wooden fence. The camera remains static with minimal movement.

A man is interacting with a mailbox, moving his arms and body while holding a cane. His motion is due to physical locomotion and actions.

Background elements (wooden fence, building, snow) are static with no significant fluid or wind motion. No fire, water, or smoke visible.


RAW CAPTION: Okay, I need to generate a caption for this video based on the user's rules. Let me start by watching the video frames provided.

First, the video starts with a close-up of hands on a table. There's a white cloth and a dark object, maybe a bottle. Then the camera moves to show two people in a room. One person is sitting on a bed with a white shirt and hair in a bun. The other person is standing next to them, wearing a dark top. The room has a bed with a colorful blanket and some clothes around.

The main actions: the camera shifts from the table to the people. The person sitting on the bed is interacting with something on the table, maybe moving objects. The standing person is close by, perhaps talking or helping. The camera moves slightly, maybe panning left to show the scene more clearly.

I need to focus on motions and behavior in order. Mention appearance briefly: two people, one in white shirt, bun; other in dark top. Spatial relationships: seated person on bed, standing next to them. Background minimal, just the bed and items. Camera movement is slight pan left and shake.

Wait, the user said to exclude text recognition, named characters, etc. So don't mention specific names or if there's text. Keep it concise, chronological.

Check the rules: chronological paragraph, motion and behavior of main subjects. Appearances: color, size, orientation. Spatial relations if relevant. Conclude with camera perspective and movement.

So, first, the camera shows hands on a table with a white cloth and dark object. Then shifts to two people: one seated on bed (white shirt, bun) interacting with items, the other standing beside them (dark top). The seated person moves hands, maybe arranging or handling objects. The standing person is close. Background has bed and clothes, but keep it minimal. Camera moves from close-up to pan left, slightly shaky.

Make sure to avoid describing the background in detail unless essential. So mention the bed briefly as part of the room.

Final caption should be a paragraph. Let me structure it:

The video opens with hands manipulating items on a table covered with a white cloth, near a dark object. The camera then pans left to reveal two individuals in a bedroom: one seated on a bed in a white shirt with hair tied in a bun, handling objects on the bed, while the other stands beside them in a dark top. The seated person moves their hands across the bed, adjusting items, with the standing person occasionally interacting. The camera remains slightly shaky, maintaining a close-up perspective that shifts to capture both subjects in the room’s cluttered setting.

Wait, but need to check if "cluttered setting" is necessary. Rule e says minimal background unless essential. The bed with colorful blanket and clothes might be essential to show the room's context. But maybe "cluttered" is okay. Alternatively, "a bed with a colorful blanket and scattered clothes" but the user said minimal. Maybe just mention the bed as part of the background.

Also, the first part: hands on table, white cloth, dark object. Then the camera moves to two people.

Another point: the video's initial frames show hands, then shifts to the people. So the sequence is table first, then the people. The camera movement is panning left and maybe a bit shaky.

Let me try to condense it:

The video begins with hands on a table covered by a white cloth and a dark object. The camera then pans left to show two people in a bedroom: one seated on a bed in a white shirt with a bun, interacting with items on the bed, while the other stands beside them in a dark top. The seated individual moves their hands across the bed, adjusting objects, as the standing person occasionally engages. The camera remains slightly shaky throughout, maintaining a close-up perspective that shifts to frame both subjects against the bed and surrounding clutter.

Check for chronological order. Correct sequence: starts with hands on table, then camera moves to people. Then the actions of each person.

Wait, in frame 0, hands on table; frame 1-2, transition; frame 3, two people. So the motion is from table to the people. So the caption should say the camera shifts from the table to the two people.

Also, the user's rules say "concise, chronological paragraph describing the provided video."

Possible caption:

The video opens with hands interacting with objects on a table covered by a white cloth, including a dark bottle. The camera then pans left to reveal two individuals in a bedroom: one seated on a bed in a white shirt with hair tied in a bun, moving items on the bed, while the other stands beside them in a dark top. The seated person adjusts objects on the bed, and the standing person observes. The camera maintains a slight shake, focusing closely on the subjects before shifting to

Two individuals are interacting with dough using a rolling pin, applying physical forces to roll the dough. The dough and rolling pin exhibit distinct motion due to manual manipulation.

The background elements (bed, walls, tables) show no significant shifting or fluid motion. No fire, water, smoke, or wind-driven effects are present.


A pair of hands with white nail polish manipulates a needle and thread; the left hand holds the needle while the right hand threads the thread through the needle's eye, then the right hand brings red scissors into view to cut the thread. The scene is shot from a top-down perspective against a dark brown fabric background.

The hands (discrete solid objects) are moving to thread a needle; the needle and thread are also moving but are driven by the hands.

The background is a static dark textured surface with no shifting or environmental motion. No fire, water, smoke, or wind observed.


Two individuals collaborate on a metal vehicle component; one person in a blue shirt steadies a bolt while the other, wearing a wristwatch, turns a wrench to adjust it. Their hands move in coordination to tighten or loosen the bolt, with the wrench rotating against the metal structure.

RAW CAPTION: Got it, let's break this down. The video shows a young boy on the beach playing with sand. First, the boy is sitting, and there's an adult helping him. The adult uses a pink bucket. Let's track the sequence.

At the start, the boy is sitting on the sand, shirtless, in blue shorts. The adult's hands are holding a pink bucket. Then the adult pours sand into the bucket, maybe? Wait, the actions: in frame 0, adult is holding pink bucket, boy is touching sand structures. Then frame 1: adult lifts bucket, boy moves hand. Frame 2: adult pours sand from pink bucket onto the sand? Wait, the video shows the adult using the pink bucket to move sand. Let's see the motions.

Chronological order: the boy is sitting, building sandcastles. Adult's hands (wearing a swimsuit, maybe) help. The adult holds the pink bucket, pours sand into it or onto the sand. Then the boy's hand moves, and the adult's hand interacts with the sand. The background has a blue inflatable toy.

Main subjects: boy (shirtless, blue shorts), adult (hands visible, swimsuit). Actions: adult uses pink bucket, pours sand, boy assists or touches.

Spatial: boy in center, adult's hands from the right. Sandcastles around boy.

Background: sandy beach, blue inflatable (minimal, as per rules).

Camera: top-down view, probably static.

Now, structure the caption.

Start with the boy sitting, sandcastles around. Adult uses pink bucket. Sequence: adult pours sand from pink bucket, boy moves his hand, then adult continues. Mention the motion step by step.

Check rules: chronological, main subjects' motions, appearance (boy shirtless, blue shorts; pink bucket), spatial (adult's hands to the right of boy), camera top-down.

Avoid background details unless essential. The blue inflatable is in the background, but maybe mention as minimal.

Let's draft:

A shirtless boy in blue shorts sits on the sand, building sandcastles. An adult’s hands hold a pink plastic bucket and pour sand onto the structures, while the boy moves his hands to assist. The adult then lifts the bucket, and the boy reaches out toward the sand. The camera maintains a top-down perspective throughout the sequence.

Wait, check the frames: first frame, boy is touching sand, adult holds bucket. Then adult pours sand, boy moves hands. Then adult lifts bucket, boy touches sand. So step by step:

- Boy sits, building sandcastles. Adult uses pink bucket to interact with sand (pouring, maybe). Boy moves his hand. Adult’s hand works with sand, boy touches.

Let's make it concise:

A shirtless child in blue shorts sits on the sand, surrounded by sandcastles. An adult’s hands hold a pink plastic bucket, pouring sand onto the structures; the child moves their hands to assist. The adult lifts the bucket, and the child reaches toward the sand. The camera remains stationary in a top-down view.

Check if background is minimal: "sandy beach" is implied, but the blue inflatable is in the background. Wait, rules say minimal unless essential. The blue inflatable might be essential for context (beach), but maybe just mention "sandy beach" without specific items. The problem says "background descriptions minimal unless essential for understanding motion." Since the inflatable isn't part of the main action, maybe skip it. So focus on main subjects.

Let me check the initial frames:

Frame 0: boy sitting, adult's hand with pink bucket. Sandcastles in front.

Frame 1: adult pours sand, boy's hand reaches.

Frame 2: adult pours, boy moves hand.

Frame 3: adult pours, boy touches.

So actions: adult uses pink bucket to move sand, boy interacts.

Final caption:

A shirtless child in blue shorts sits on the sand, building sandcastles. An adult’s hands hold a pink plastic bucket and pour sand onto the structures, while the child moves their hands to assist. The adult lifts the bucket, and the child reaches toward the sand. The camera remains stationary in a top-down view.

Wait, but the video might be showing the adult pouring sand into the bucket first? Wait, the first frame: adult is holding the pink bucket, then the next frame, the adult is pouring sand (maybe into the bucket?) but no, the child is interacting with the sand. Wait, looking at the frames:

In frame 0, the child is sitting, and the adult's hands are holding the pink bucket, with the child touching the sand. Then in frame 1, the adult pours sand (from the bucket onto the sand?), and the child moves his hand. Then frame 2: adult pours, child moves. Frame 3: adult

The boy and adult's hands are the discrete objects moving: the boy pours sand from a pink bucket, adjusts the bucket, and interacts with sand structures; the adult assists by holding and moving the bucket.

No shifting backgrounds or fluid/environmental motion observed. Sand and static background elements (e.g., blue toy) remain stationary throughout the clip.


A man wearing a black shirt, cap, and chain sits outdoors, holding a dark textured pipe in one hand and a light-colored cylindrical object in the other. He rotates the pipe slightly while maintaining grip on the object, adjusting their positions to display details. The background features a house with siding and a window with decorative metal. The camera remains stationary, focusing on the man’s upper body and hands.

A person is actively manipulating a small object (likely a bottle) and another item in their hands, exhibiting discrete hand movements.

Background elements (railing, siding) remain stationary across frames; no fluid/environmental motion (fire, water, smoke, wind) observed.


A hand stirs a vibrant green liquid in a clear glass bowl with a metal spoon. White granular powder is then added and mixed into the green liquid, followed by pink powder which is stirred until the mixture turns pink. The camera remains in a top-down perspective throughout, focusing on the bowl and its contents against a light surface.

Discrete objects: a metal spoon (manually stirred through the liquid), a hand (holding the spoon), and solid powder (added and mixed). These objects interact via physical forces (stirring), not fluid/environmental motion.

The background (white countertop) remains static with no uniform shifting. The liquid mixing is contained within the bowl and not a free-flowing environmental fluid (e.g., no fire, water flow, smoke, or wind), thus not qualifying as ambient_environmental.


A baby wearing an orange shirt crawls on a tiled floor, reaching for a small silver toy car, then moves it across the tile to a nearby carpet where the baby continues to interact with the car, occasionally adjusting its position. The background includes wooden chairs with red cushions, and the camera follows the baby's movement closely, maintaining a low-angle perspective throughout.

Baby (solid object) crawling and pushing a toy car (solid object) across the floor; the car moves due to the baby's physical force.

No shifting background or fluid/environmental motion; background elements (chairs, floor) are static.


A person hangs from an upper window of a beige building; two individuals approach from the right and stand on a blue mat below, one in blue shorts and another in gray shirt. The hanging person begins descending toward the mat as the two on the ground watch; the camera remains stationary.

Two people on the blue mat are walking and interacting, exhibiting discrete locomotion.

Background elements (building, blue mat) show no uniform shifting; no fire, water, or wind-driven motion observed.


RAW CAPTION: Okay, let's see. I need to create a caption for this video clip. The user provided some rules, so I have to follow them carefully.

First, the video shows a futsal game. There are two teams: one in orange jerseys, the other in white. The score is 2-1. The main action is a player in orange trying to score. Let me check the timestamps. The video starts with the team in orange, then the ball is moved towards the goal. The player in orange shoots, the goalkeeper in white saves it. Then another player in orange tries to score again but maybe the goalie blocks it again. Wait, the sequence: at 0.0s, the players are moving. Then at 1.0s, the ball is being kicked towards the goal. The player in orange (number 10 maybe) is running towards the goal. Then the goalkeeper is there. The goal is defended by white team players. Then the ball is shot, the goalkeeper saves it. Then another attempt.

Wait, the user says to focus on motion and behavior in chronological order. So first, players in orange and white are moving on the court. The orange team is attacking, the white team defending. The ball is passed, then the orange player shoots, the goalkeeper stops it. Then the other player tries again, but maybe the goalie blocks. Then the video ends.

Wait, the first frame shows the score 2-1. Then the next frames show the orange team attacking. The orange player (10) is passing, then shooting. The goalkeeper (white) saves it. Then another orange player maybe tries to score again. But need to be concise.

Appearance: orange and white jerseys. Number of players: several, but maybe don't need specific numbers. Spatial: the orange players are on one side, white on the other. The goalkeeper is near the goal.

Camera perspective: top-down view, as it's a futsal court. The camera is stationary or maybe panning slightly.

Background: minimal, the court is blue, ads on the walls but user says minimal, so maybe not mention.

Rules exclude text recognition, so ignore the score and names like "CARLOS BARDOS" etc.

So the caption should mention the orange team attacking, passing the ball towards the goal, the white goalkeeper saving it, then another orange player attempting a shot.

Need to order chronologically:

1. Orange team players move towards the white team's goal.

2. A player in orange passes the ball towards the goal.

3. The white team goalkeeper positions himself to block.

4. The ball is shot by an orange player, saved by the goalkeeper.

5. Another orange player attempts a shot, but the goalkeeper blocks again.

Wait, but the video might be showing the action of the first shot. Let me check the frames:

At 0.0s: players moving, maybe the orange team has the ball. At 1.0s: the ball is being directed towards the goal. The orange player (10) is running towards the goal. The white goalkeeper is there. The player in orange shoots, the goalkeeper saves. Then another player in orange tries to score but the goalkeeper blocks. Then the scene ends.

So the caption needs to describe this in order.

Possible caption:

"Players in orange jerseys advance toward the white team's goal, passing the ball to a teammate who shoots. The white goalkeeper dives to save the shot, followed by a second orange player attempting a goal but the goalkeeper blocks the ball. The camera maintains a top-down view throughout the sequence."

Check the rules: no text recognition, so don't mention scores or names. Focus on motion, chronological order. Mention appearance (colors), spatial relationships (toward the goal, goalkeeper's position). Conclude with camera perspective.

Make sure to be concise. Maybe:

"Two teams, one in orange and one in white, compete on a blue court. An orange player passes the ball toward the white team's goal, where the goalkeeper positions himself. The orange player shoots, and the goalkeeper saves it. A second orange player attempts a shot but is blocked by the goalkeeper. The camera captures the action from a top-down perspective."

Wait, but the user says "mention spatial relationships if relevant". So "the goalkeeper positions himself in front of the goal". Maybe "the white goalkeeper stands in front of the goal to block the shot".

Also, need to check if there are two attempts. The video might show two shots: first save, then another attempt.

The video frames: first frame shows the teams set up, then the ball is being moved, then shot, then goalkeeper saves, then another shot maybe.

But since the user's sample caption might have specific details. Wait, the output example is just a structure.

Wait, in the first frame, the players are moving. Then the orange team is

Discrete solid objects include players (red/white jerseys), referee (orange), and ball moving via physical forces: kicks, collisions, and locomotion. These objects maintain distinct bounding boxes and clear motion paths.

The background elements (banners, walls, court boundaries) are stable and show no shifting or fluid motion. No environmental phenomena (fire, water, smoke, wind) are present.


A hand manipulates a green checkered elastic band, moving it toward a white cap with a black and red logo on a dark surface; the hand positions the elastic beside the cap, with blue-handled scissors visible in the background. The camera maintains a top-down perspective throughout.

A hand manipulates a green elastic band, causing it to stretch and move due to applied force.

Background elements (white cap, blue scissors, table surface) show no uniform shifting or environmental motion (no fire, water, or wind).


Three men stand in a room with a clock and couch in the background as a timer counts down from 3 to 0. The man on the left bends toward a cone as the timer hits 2, then quickly moves as it reaches 0, while the center man gestures with his hands and the right man shifts position. The camera remains static, capturing the scene from a frontal view.

Three people exhibit discrete solid-object motion: the person in gray tank top bends to pick up a cone and performs exercises, the person in black shirt gestures while speaking, and the person in white shirt sits/stands on the couch.

No shifting background elements (clock, couch, staircase remain stationary). No fire, water, smoke, or wind motion detected.


A girl in a dark blue shirt and jeans stands at an outdoor sink, wringing a green cloth. She then lifts the cloth upward. A man in a blue shirt, white cap, and blue shorts enters from the right, holding an object, and stands to her right. The camera remains stationary throughout.

A girl (discrete object) is actively washing a green item with hands, exhibiting deliberate motion (wringing, rubbing). A man (discrete object) stands stationary nearby, observing.

Background elements (wall, shutter) show no uniform shifting; no fire, water flowing, smoke, or wind-driven motion observed. Water in the sink is contained and part of discrete object interaction, not ambient fluid motion.


Two men sit on a bench against a brick wall; one in a white polo shirt and dark shorts manipulates the extended foot of the other man, who wears a white polo shirt and blue shorts. The man with dark shorts uses both hands on the foot, adjusting his grip throughout the sequence. The camera remains stationary, capturing the interaction from a side angle.

Two people: one seated with leg extended on a bench (patient), the other seated (practitioner) moving hands in rhythmic motion on the patient's leg (massage). Motion is discrete and localized to the hands/leg.

The tiled wall and concrete bench background show no shifting or environmental motion (e.g., wind, water). No fluids or atmospheric effects are present.


A person wearing a black horned mask and dark shirt brushes their teeth with a blue toothbrush in a bathroom with white tiled walls. They move the toothbrush in their mouth, turn their head to the right, and face forward again, while animated blue cassette tapes and stars appear as overlays. The camera remains mostly stationary with a slight shake.

The child's head and toothbrush are moving due to brushing teeth; the toothbrush is a discrete object moving in the mouth. The child's head turns and moves.

Background consists of static bathroom tiles and sink. No fluid/environmental motion (fire, water, smoke, wind) is dominant. Animated graphics are part of video editing and not real environmental motion.


A person's hands manipulate a vibrant art book, flipping pages to reveal colorful craft projects including pink and blue floral decorations on one page and a green grid design on the next. The hands move sequentially, turning the book's pages which display various patterns and colors. The camera maintains a top-down view throughout, capturing the motion of page-turning without shifting perspective.

Discrete objects: the person's hands and the art book. Hands are actively flipping pages, moving art pieces, and manipulating the book's contents in controlled motions.

The background (patterned fabric) is static with no shifting or environmental motion. No fire, water, smoke, or wind is present.


A person in a red shirt dances energetically in front of a light-colored couch, moving their arms and upper body rhythmically while shifting positions; a framed picture hangs on the wall behind them. The camera maintains a fixed perspective with minimal movement, capturing the subject against a dimly lit room background.

A person in a red shirt is moving their arms rhythmically. The motion is deliberate and consistent with human locomotion (e.g., dancing or gesturing), with no other discrete solid objects moving.

The background (couch, framed picture, wall) shows no uniform shifting or fluid motion. No fire, water, smoke, or wind is present. Musical notes are digital overlays, not environmental elements.


A child in a blue shirt with a headband leans over an adult in a red patterned top, both seated. The child moves their head, looks around, and shifts position while the adult remains still, holding a container with a light-colored substance. The camera maintains a top-down perspective with slight shake, capturing minimal background details.

Two children (a girl and an adult) exhibit subtle motion: the girl turns her head, blinks, and shifts position while sitting; the adult remains mostly static with minor head movements. Motion is self-driven locomotion without collisions or external forces.

No shifting background elements; green wall and countertop remain stationary. No fluid/environmental motion (fire, water, wind, smoke) observed beyond the static water bottle.


A female news anchor with long dark hair, wearing a black blazer over a white shirt, sits in front of a vibrant studio backdrop with blue and orange curved patterns. She speaks while making expressive hand gestures, moving her hands up and down to emphasize her points. The camera remains stationary, maintaining a steady frontal view of the anchor throughout the sequence.

The news anchor is the primary discrete object, exhibiting controlled hand gestures and body movements consistent with speech delivery.

Background features a static colorful graphic design (blue/yellow curves) with no visible shifting or fluid motion. No fire, water, smoke, or wind-driven elements observed.


A blue-gloved hand enters the frame from the left, reaching toward the engine bay of a car with the hood open. The hand, holding a yellow-handled tool, moves across the engine components. The background features wooden panels, and the camera remains stationary in a top-down view throughout.

A person wearing blue gloves is moving their hands and arms to interact with objects in the car engine bay.

The wooden panels and wall in the background are static; no fluid motion (fire, water, smoke, wind) is present.


RAW CAPTION: Got it, let's break down the video frames. First, there are four people sitting around a table in a room with windows. The first frame shows them at the table. Then, in the second frame, they all lean in, maybe reacting to something. Third frame is a close-up of a person in a teal shirt, and then the next frame shows another person's hand moving towards the teal-shirted person. Then the last frame is a close-up of the teal-shirted person covering their face with a hand.

Wait, need to order chronologically. Let's list the sequence:

0.0 - 0.3 seconds: Four people (various colors: denim jacket, dark shirt, teal shirt, dark shirt with cap) sit at a wooden table. Room has windows with blue/green light.

0.3 - 1.4 seconds: They lean in, maybe laughing or reacting. Camera angle shifts slightly.

1.4 - 2.5 seconds: Close-up of the person in teal shirt (blonde hair, short) as another person reaches over.

2.5 - 4.0 seconds: Teal-shirted person moves their hand, covers face with right hand (blonde hair, short).

4.0 - 4.7 seconds: Close-up of teal-shirted person's hand covering face.

Wait, the frames given are:

[0.0] - four people at table.

[1.4] - they lean in (maybe moving positions).

[2.5] - close-up of teal shirt person, then another person's hand (from right) reaching towards them.

[3.0] - hands: one hand (from right) with yellow object (maybe a card) touching the teal shirt person's hand.

[4.0] - teal shirt person covers face with right hand.

Wait, the frame breakdown:

Frame 0: Four people at table. Room with windows, lamp.

Frame 1: Same people, leaning in.

Frame 2: Close-up of the person in teal shirt (blonde hair, short).

Frame 3: Close-up of hands: the teal-shirted person's hand, another person's hand (from right) touching their hand.

Frame 4: Teal-shirted person covers face with right hand (blonde hair, short).

So chronological order:

At the start, four people are seated around a table. They lean in, adjusting their positions. The camera then zooms in on the person wearing a teal shirt with short blonde hair. Another person's hand reaches toward the teal-shirted individual, possibly handing or showing something. The teal-shirted person then uses their right hand to cover their face.

Check appearance: number of people - four. Teal shirt is a key one. The other people: denim jacket, dark shirt with red sleeve, dark shirt with cap.

Spatial relationships: the teal-shirted person is seated at the table, others around. When the hand reaches, it's from the right side of the frame.

Background: windows, lamp, but minimal as per rules.

Camera perspective: starts as a medium shot of the table, then zooms in on the teal-shirted person, then closer on hands, then closer on the face.

Wait, the rules say "conclude with camera perspective and movement". So in the caption, after describing the actions, mention camera movement.

Let's structure:

Chronological:

First, four people (denim jacket, dark red-sleeve shirt, teal shirt, dark cap shirt) are seated around a wooden table in a room. They lean in toward each other, adjusting positions. The camera zooms in on the teal-shirted individual with short blonde hair. Another person's hand extends from the right, reaching toward the teal-shirted person's hand. The teal-shirted person then raises their right hand to cover their face.

Wait, the frames: the third frame (2.5s) is a close-up of the teal shirt person's face. Then 3.0s is a close-up of hands: teal shirt person's hand and another's hand. Then 4.0s: teal shirt person covers face.

So the sequence of actions:

- Initial shot of all four at table.

- They lean in (maybe laughing or reacting).

- Camera cuts to close-up of teal shirt person (face, short blonde hair).

- Then close-up of hands: another person's hand (from right) touches teal shirt's hand.

- Then teal shirt person covers face with right hand.

Wait, in the provided frames:

Frame 0: four people at table.

Frame 1: four people leaning in (positions changed, maybe).

Frame 2: close-up of teal shirt person's face.

Frame 3: close-up of two hands (one is teal shirt's hand, the other is someone's hand reaching toward).

Frame

A boy in a teal shirt pours liquid from a bottle into another person's hand, then covers his face with his hands; other people adjust their positions and interact with objects at the table.

Background elements (windows, walls, ceiling light) show no uniform shifting; no fire, water, or smoke present, ruling out ambient environmental motion.


RAW CAPTION: Got it, let's break this down. The video shows a person sitting on the floor. First, they're adjusting pink and black sneakers. Then they pick up one shoe, showing it to the camera. Let's check the rules.

Chronological order: Start with sitting, adjusting shoes. Then pick up a shoe. Appearance: person wearing a white and blue sleeveless top, red pants, sneakers are black with pink laces and soles. Spatial: sitting on the floor, shoes in front. Background: room with dresser, bed, etc., but minimal. Camera: static? The description says "slight shake" maybe, but the video might be handheld. Wait, the user says to mention camera perspective and movement. The video is likely a handheld shot, so camera might be stationary or slight shake. Wait, the problem says "conclude with camera perspective and movement".

Let's structure:

- Person sits on floor, adjusts pink/black sneakers (black with pink laces, soles). Then picks up a shoe, holds it up to camera.

Main subject: person, actions: sitting, adjusting shoes, holding up a shoe.

Appearance: person has short dark hair, white/blue top, red pants. Shoes: black with bright pink laces and soles.

Spatial: shoes on blue rug, person in front of dresser and bed.

Background minimal, so just mention if essential. The room has furniture, but maybe not necessary unless it affects motion.

Camera: likely static or slight shake, but since it's a video, maybe handheld, so slight shake.

Now, write concise paragraph.

"Person sits on blue rug, adjusts black sneakers with bright pink laces and soles. Then picks up one shoe, holds it toward camera. Person wears white and blue sleeveless top and red pants. Background includes dresser and bed. Camera is static with slight shake."

Wait, check rules: "Briefly describe their appearance and number (color, size, orientation)". Number: one person.

Chronological: first adjusting shoes, then picking up a shoe.

Background minimal: so "background includes dresser and bed" is minimal.

Camera: "static with slight shake" as per common handheld shots.

Let me check if all rules are covered:

a) Motion chronological: adjusting, picking up.

b) Appearance: person's top, pants, shoes.

c) Spatial: sitting on rug, shoes in front.

d) Camera: static with slight shake.

e) Background minimal: yes.

f) Exclude text, etc.: done.

Now, write it concisely.

"Person sits on a blue rug, adjusting black sneakers with bright pink laces and soles, then lifts one shoe to face the camera. The individual wears a white and blue sleeveless top and red pants, positioned in front of a dresser and bed. Camera remains static with slight movement."

Wait, "slight movement" instead of shake? The problem says "slight shake" in the example. Wait, the user's output format example says "slight shake". But maybe the video's camera is handheld, so slight shake.

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

So if the camera is at a low angle, but the video shows the person sitting, so maybe the camera is positioned low, like looking up at them. Wait, the first frame shows the person bending over, then sitting. The camera angle might be low, but the problem says "camera perspective". Wait, the video is shot from the floor level, so perspective is low angle (looking up). But maybe not specified. Wait, the user says "focus on motion and behavior", so maybe the camera is static.

Wait, the problem says: "Conclude with the camera perspective and movement". So we need to state it.

Let's think: the video starts with the person bending, then sitting. The camera is stationary, maybe handheld, so slight shake.

But let's check the video description: the user provided the video clips. In the frames, the person is moving, so the camera might be static.

So possible caption:

"A person sits on a blue rug, adjusting black sneakers with bright pink laces and soles, then lifts one shoe to show the camera. The individual wears a white and blue sleeveless top and red pants. Background includes a wooden dresser and bed. Camera is static with slight shake."

Check length. Need to be concise.

Trim:

"Person sits on blue rug, adjusts black sneakers with bright pink laces and soles, then holds one shoe toward camera. Wears white/blue sleeveless top and red pants. Background features dresser and bed. Camera is static with slight shake."

Yes, that's concise.

RAW CAPTION: Got it, let's break this down. First, the video shows a sheep shearing event. The main subjects are people and sheep. Let's list the sequence.

Start with the first frame: several people around sheep. A woman in black shorts is bending over a sheep, maybe shearing. There's a man in pink shirt, another in white cowboy hat, red shirt with lanyard. The timer is at 20 seconds initially. Then as time goes (20 to 24 seconds), the shearing continues. Some people move around, like a man in gray shirt handling another sheep. The sheep are on the ground, being sheared. People are standing around, some assisting. The crowd is in front, watching.

Need to note appearance: people in various colors (pink, red, black, white), sheep are woolly, being sheared. Spatial: people in front and behind barriers, sheep on ground. Camera is static, maybe slightly shaky, looking down at the scene.

Chronic order: Start with shearing actions, then more people moving, shearing continues, timer changes from 20 to 24.

Avoid text recognition, so don't mention the "American" signs or exact numbers. Focus on motion.

Let me structure:

In the video, multiple people shear sheep at an event. A woman in black shorts bends over a sheep while others assist; a man in a pink shirt and another in a red shirt with a lanyard stand nearby. As the timer progresses from 20 to 24 seconds, more individuals move around the sheep, handling them and trimming wool. The crowd observes from the front. The camera remains stationary with a slight shake, capturing the activity from a slightly elevated angle.

Wait, check rules: don't mention text, so no timer numbers as part of the scene? Wait, the timer is part of the background. The rule says exclude text recognition, but the timer is a display, not text to recognize. Wait, no, the rules say: "Exclude text recognition, named characters, or stylistic analysis." So the timer's numbers are text, so we shouldn't mention the specific numbers. Oh right, the instruction says "Exclude text recognition"—so we can't talk about the timer showing 20, 21, etc. So need to say the timer is present but not describe its numbers.

So adjust: "the timer displays seconds as the event progresses" but since we can't mention text, just say "a timer counts down" or "the timer shows elapsed time".

Wait, the example in the problem statement: "Exclude text recognition", so in the caption, we shouldn't reference the numbers on the timer. So describe the timer as present but not its numbers.

Let me rephrase:

In the video, several people shear sheep at an outdoor event. A woman in black shorts bends over a sheep while others assist; a man in a pink shirt and another in a red shirt with a lanyard stand nearby. As the event continues, additional individuals move around the sheep, trimming wool. The crowd observes from the front. The camera remains stationary with a slight shake, capturing the activity from a slightly elevated angle.

Check spatial relationships: "a woman in black shorts bends over a sheep" (spatial: bending over), "others assist" (nearby), "people in front of barriers" (since there are barriers separating them from the sheep).

Also, the sheep are being sheared, so the action is shearing.

Make it chronological: start with shearing, then movement of people, continuing shearing.

Another point: the sheep are on the ground, with wool on the floor.

Let's try:

At an outdoor shearing event, multiple people shear sheep. A woman in black shorts bends over a sheep while others assist; a man in a pink shirt and another in a red shirt with a lanyard stand nearby. As the event progresses, additional individuals move around the sheep, trimming wool, with more people joining the shearing process. The crowd observes from the front of the barriers. The camera remains stationary with a slight shake, capturing the activity from a slightly elevated angle.

Check rules: focus on motion and behavior, chronological. Yes.

Exclude text recognition: no numbers mentioned, just "event progresses".

Appearance: woman in black shorts (color, what she's wearing), man in pink, red shirt with lanyard.

Spatial: "in front of barriers", "bends over a sheep".

Camera: stationary with slight shake, slightly elevated.

Yes, that works.

Multiple people and potentially animals (e.g., horses) exhibit deliberate movement—leaning, adjusting positions, and interacting—indicating solid, distinct objects responding to physical forces (locomotion, human action).

Background elements (fences, signs, and structures) remain stationary with no visible uniform shifting; no fire, water, smoke, or wind-driven fluid motion detected.


A maroon puppet with a green mouth and two eyes is manipulated by a hand, moving its head up and down while repeatedly opening and closing its mouth. The puppet remains centered in the frame, with a bed and black object visible in the background. The camera remains stationary throughout.

A hand manipulates a solid red object with a green circular component (likely a toy or hat), exhibiting up/down motion via manual movement.

Background elements (wall, table, furniture) show no uniform shifting; no fire, water, smoke, or wind present.


A close-up of Segway wheels on a grassy field transitions to a wider shot revealing two people riding Segways. The man on the left wears a dark shirt, light pants, and a dark helmet, while the woman on the right wears a black shirt, red shorts, and a light blue helmet. Both ride forward, the man gesturing with his right hand as they move. The camera follows their motion, maintaining a slightly shaky perspective as they travel across the open grassy area with distant trees in the background.

Two people on Segways are moving steadily forward from right to left. Their motion is due to active locomotion (self-balancing technology), with clear, distinct bounding boxes tracking the riders and vehicles.

The background consists of a static grassy field with no fluid motion (fire, water, smoke, or wind effects). The grass remains uniform and unchanging throughout the clip, indicating no ambient environmental motion.


RAW CAPTION: Okay, let's tackle this video captioning task. First, I need to understand the user's requirements. They want a concise chronological paragraph describing the video, following specific rules. Let me break down the instructions again to make sure I don't miss anything.

The main points are: focus on motion and behavior of main subjects in order, describe appearance and number briefly, mention spatial relationships if relevant, conclude with camera perspective and movement, keep background minimal, exclude text recognition, named characters, or stylistic analysis.

Looking at the provided video frames, the main subject is a hand playing a ukulele. The video shows a close-up of the ukulele's body and fretboard with a hand strumming or fretting the strings. The hand is moving across the strings, probably pressing down on the frets and strumming. The background has some fabric with a pattern, but it's not essential to describe unless necessary.

First, the chronological order: the hand is initially positioned on the strings, then moves to press different frets, maybe strumming. The appearance: the ukulele is wooden, brown, with a sound hole. The hand is a person's hand, size and color (skin tone) mentioned. Spatial relationship: the hand is on the fretboard, in front of the sound hole.

Camera perspective: close-up, focusing on the hand and ukulele. There's no movement mentioned in the frames, so maybe a static shot. The user says to exclude text recognition, so ignore "Kumu Kealoha 808Ukejams" even though it's there.

Now, structure the caption. Start with the main subject and action. The hand is playing the ukulele. Mention the motion: strumming and fretting. Appearance: wooden ukulele, hand pressing strings. Spatial: hand positioned over the fretboard. Camera: close-up, static.

Check if background is essential. The fabric in the background is there, but the user says minimal background descriptions. Maybe mention "dark patterned fabric" but only if necessary. However, the example output in the instructions doesn't include background unless essential. The user's example might have omitted it, so perhaps it's okay to skip unless critical.

Wait, the user's example output in the rules says "keep background descriptions minimal unless essential for understanding motion." Since the motion is the hand playing the ukulele, the background isn't essential, so skip it.

So, the caption should be: A hand with light skin tone strums and presses strings on a brown wooden ukulele, moving fingers across the fretboard. The hand remains centered on the instrument, with the sound hole visible. The camera maintains a static close-up shot focusing on the hand and ukulele.

Wait, check for chronological order. The action starts with the hand pressing strings, then strumming. The video shows the hand in motion over the strings, so the caption should describe the sequence.

Possible correction: The hand strums the ukulele's strings, moving fingers to press different frets on the wooden instrument's fretboard. The hand stays positioned over the strings, with the sound hole visible. The camera remains fixed in a close-up view.

Wait, in the video, the hand is pressing down on the strings, maybe using a fingerpicking technique. The description should mention the motion as strumming or plucking. The user's example might have "strums and presses strings".

Let me check the example. The user provided an example output format. Wait, no, the user provided the rules and the output format. Wait, the user says: "Your task is to generate a concise, chronological paragraph describing the provided video."

The video shows the hand in motion. The first frame shows the hand on the strings, then moving fingers. The key motions are strumming and fretting.

So the caption should be: A hand with light skin tone strums the strings of a brown wooden ukulele while pressing various frets on the fretboard. The hand moves rhythmically across the instrument's strings, with the sound hole visible below. The camera maintains a static close-up view focused on the hand and ukulele.

Check if "light skin tone" is necessary. Rule b says "briefly describe appearance and number (color, size, orientation)". So the hand's color (skin tone) is part of the appearance. The ukulele is brown wooden.

Also, mention spatial relationships: the hand is positioned over the fretboard, in front of the sound hole.

Wait, the sound hole is part of the ukulele's structure, so the hand is on the fretboard which is above the sound hole. The hand is positioned over the strings, which are in front of the sound hole.

But maybe the description can be more concise. Let's see.

Another possible version: A hand

A hand (discrete solid object) is moving to press strings and strum the ukulele.

Background is static (ukulele and fabric); no fluid/environmental motion (fire, water, wind) detected.


A child in a blue striped shirt holds a black and tan German Shepherd's front paw on a tiled floor, gently manipulating it upward and downward. The dog lies calmly beside the child, observing the movement with its head slightly raised. The camera maintains a close-up, top-down perspective with minimal shake throughout the sequence.

The person's hands, a dog, and a small animal (puppy or kitten) are moving: hands manipulate the small animal, dog moves its head and mouth (licking/sniffing), and the small animal is held and moved by the person.

No shifting background (carpet remains static); no fluid or environmental motion (e.g., fire, water, wind) observed.


A person in white clothing jumps over a small wooden stool, moving from left to right across a concrete patio. The individual’s motion starts with a leap over the stool, landing on the opposite side. Background includes a dense hedge and trees, with minimal detail. The camera remains stationary throughout.

A person in white clothing is moving across the scene, performing actions that involve locomotion and interaction with objects on the ground (e.g., buckets).

Background elements (hedges, trees, wooden structure) are stationary with no visible shifting or fluid motion (fire, water, smoke, wind) detected.


A child in a teal shirt with braided hair adorned by yellow beads and a pink headband holds a red pen. She begins writing, then lifts the pen upward. The background features a plain white curtain. The camera maintains a close-up perspective with slight movement.

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


A dark-skinned hand adorned with a ring and colorful patterned sleeve moves across a white fabric, smoothing it from right to left. The hand continues to adjust the fabric, shifting positions while maintaining contact. The camera stays close to the hand and fabric, capturing minimal movement as it focuses on the action.

A hand (with visible rings and watch) is actively folding and moving a white fabric sheet. The hand is the primary discrete object applying physical force to the fabric, causing it to shift and reposition.

The background (patterned fabric) shows minimal motion and no fluid/environmental elements like fire, water, or wind. The white fabric is being manipulated by a hand, which is solid and distinct.
