Two boys sit at a table; the boy on the left, wearing a white and green patterned sweater, brings food to his mouth while the boy on the right, in a bright yellow shirt with blue accents, eats from a plate. The left boy touches his face, and the right boy gestures with his hands. The camera maintains a close-up perspective with slight movement.

Two children exhibit discrete physical motion: eating (hand-to-mouth actions), handling napkins, and interacting with food items on a table.

Background elements (stacked books, wall) show no uniform shifting; no fire, water, or smoke present in the scene.


A person in a light blue shirt sits on the floor with a tabby cat resting on their lap; the person uses a brush to groom the cat's head and neck, moving the brush in circular motions while the cat remains still. The cat has brown and white fur with visible stripes. The camera maintains a close-up, static perspective focused on the interaction between the person and the cat.

The person's hands are moving while brushing the cat, and the cat is moving its head and body in response to the brushing action.

The background (floor, chair, blue object) is static with no shifting or environmental motion (fire, water, wind).


A person in a red shirt holds a dark-colored pipe, rotating it to display its shape and bowl. They move the pipe toward the camera, then position it near their face while adjusting its angle. The camera remains stationary throughout the sequence.

The person's hands manipulate a solid pipe object, moving it through distinct motions (rotation, positioning) with visible physical interaction.

Background elements (chair, grass, trees) remain stationary and show no uniform shifting; no fire, water, smoke, or wind motion observed.


RAW CAPTION: Got it, let's break down the video. First, the main subject is a person. Let's see their appearance: they're wearing a dark blue shirt, light blue jeans, black shoes, and a black cowboy hat. They're moving across the room. The video starts with them standing on the left side of the frame. Then they walk towards the center. In the next frame, they're moving forward, then they raise their right arm and then both arms.

Now, chronological order: first, the person is standing near the left, then walks toward the center, then raises their arms. Let's check the background. There's a wooden floor, red curtains, some red cushions, and windows with red balloons. But the rules say minimal background unless essential. So maybe just mention the setting briefly.

Spatial relationships: the person moves from left to center, then does arm movements. The camera is static, I think, since no movement is mentioned. The output should be concise, paragraph form.

Let's structure it:

A person wearing a dark blue shirt, light blue jeans, black shoes, and a black cowboy hat walks across a wooden-floored room from the left side toward the center. They raise their right arm, then both arms, moving their hands in an upward motion. The background includes red curtains and a wall with framed pictures, but camera remains stationary with a frontal view.

Wait, need to check the frames. Frame 0: standing on left. Frame 1: walking. Frame 2: walking. Frame 3: moving forward. Frame 4: raising right arm. Frame 5: raising both arms. So sequence: walks toward center, then raises arms.

Also, appearance: color, size (but maybe just "a person" without size unless needed. The rules say "color, size, orientation" for main subjects. So the person's clothing colors: dark blue shirt, light blue jeans, black shoes, black hat.

So putting it all together:

A person wearing a dark blue shirt, light blue jeans, black shoes, and a black cowboy hat walks across a wooden-floored room from the left side toward the center, then raises their right arm followed by both arms in an upward motion. The background features red curtains and framed pictures on the wall. Camera remains stationary in a frontal perspective.

Wait, the background is minimal. The rules say "background descriptions minimal unless essential for understanding motion." Here, the red curtains and frames might be necessary to set the scene, but maybe not. Let's see. The motion is the person walking and raising arms. The background elements like red cushions, balloons, etc., might not be essential. Maybe just "a room with red curtains and framed pictures on the wall."

Wait, the rules say "briefly describe their appearance and number (color, size, orientation)." So the main subject's appearance: color (dark blue shirt, light blue jeans, black shoes, black hat), size (probably assume adult, but maybe not necessary), orientation (standing, walking).

Chronological order: starts on left, walks toward center, raises right arm, then both arms.

Camera: stationary, frontal view.

Let me check the frames again. The first frame: person standing on the left. Then moves right. So starts on left, moves toward center.

Now, the caption should be:

A person dressed in a dark blue shirt, light blue jeans, black shoes, and a black cowboy hat walks from the left side of a wooden-floored room toward the center, then raises their right arm followed by both arms upward. The background includes red curtains and framed pictures on the wall, with the camera remaining stationary in a frontal perspective.

Wait, but the rules say "exclude text recognition, named characters, or stylistic analysis." So no "dress in" but "wearing" maybe. Also, "briefly describe their appearance and number (color, size, orientation)." So the person's appearance: color of clothing.

Let me rephrase:

A person wearing a dark blue shirt, light blue jeans, black shoes, and a black cowboy hat moves from the left side toward the center of a room with a wooden floor, raising their right arm and then both arms in an upward motion. The background has red curtains and framed pictures on the wall; the camera remains stationary.

Yes, that's concise. Let's check if all rules are met.

a) Motion and behavior in order: walking from left to center, raising arms.

b) Appearance: dark blue shirt, light blue jeans, black shoes, black hat. Number: one person.

c) Spatial: from left to center.

d) Camera: stationary, frontal.

e) Background minimal: red curtains, framed pictures.

f) No text recognition, named characters.

g) Internal thoughts done.

So final caption:
</think>

<caption_output>A person wearing a dark blue shirt, light

A person is moving by walking in place and performing arm gestures.

The background (red curtains, wall frames) is static with no shifting or environmental fluid motion.


A woman wearing a pink sari with long black hair stands on a balcony with ornate railings and terracotta pots. She holds a black cloth, swinging it in a circular motion, then allowing it to fall to her side. The camera remains stationary, capturing her from a frontal perspective as she maneuvers the cloth in fluid, rhythmic movements.

The woman in the pink dress is actively manipulating a black cloth (dupatta) through deliberate arm movements and body turns, causing the cloth to flow dynamically. This motion is driven by her physical actions.

The background (railing, potted plants, walls) shows no shifting or environmental motion. No fire, water, smoke, or wind is present as the dominant motion.


RAW CAPTION: Got it, let's break down the video. First, look at the sequence. There are several people. In the first frame, one person is upside down on a structure, another is jumping over. Then the next frames show movement: people jumping, climbing, moving around. Let's list the main actions chronologically.

Start with the initial scene: a person in a green shirt is on a white structure (like a bench or box), upside down, arms up. Then two people in dark clothes jump over a wooden fence (white posts). One person jumps from the fence onto the structure where the green-shirted person is. Then another person in dark clothes is on the fence, and the green-shirted person moves. Then people are moving around, maybe falling or landing.

Wait, need to track each step. Let's check each frame:

[0.0] Frame 0: Person in green shirt is upside down on a white structure (horizontal), arms up. A person in dark shirt (maybe black) is jumping from the right side (over a wooden fence), then another person (same dark shirt) is jumping. The person in the green shirt is on the structure, then in frame 1, the person in dark shirt jumps over, then in frame 2, they land on the structure, and the green-shirted person is moving. Then in frame 3, the person in dark shirt is on the structure, and another person is behind. Then frame 4, the person in dark shirt is stepping down from the structure, and the green-shirted person is holding onto the structure. Then frame 5, the person in dark shirt is moving away.

Wait, need to describe the main subjects (people) in chronological order.

Main subjects: Let's count. There are at least three people visible. Let's see:

1. Person in green shirt (smaller, wearing green, on the white structure).
2. Two people in dark clothing (black shirts, dark pants, maybe).
3. Another person in dark clothing (maybe, but maybe not, but the video shows multiple).

Wait, let's describe each action step by step.

Frame 0: A person in a green shirt is upside down on a white structure, arms raised. Two people in dark clothing jump over a wooden fence (white posts). One of the jumpers lands on the structure where the green-shirted person is.

Frame 1: The person in green is still on the structure, the jumper (dark shirt) is now on the structure. Another person (dark shirt) is on top of the fence.

Frame 2: The person in green is now on the ground or moving? Wait, no. Let's see. The first jumper (dark shirt) lands on the structure, then another person (dark shirt) jumps over the fence and lands on the structure. The green-shirted person is moving.

Wait, maybe better to list the sequence:

1. A person in green shirt is suspended upside down on a white wooden structure, arms extended upward.

2. Two individuals in dark clothing jump sequentially over a wooden fence; the first lands on the structure where the green-shirted person is, while the second continues jumping over the fence.

3. The green-shirted person adjusts their position on the structure, moving downward, and the first jumper (dark clothing) steps off the structure.

4. The second jumper (dark clothing) descends from the fence and approaches the structure.

5. The scene concludes with people moving around the structure, one person standing on the structure, another moving away.

Wait, but need to be concise. Let's make sure it's chronological. Also, mention spatial relationships: e.g., the green-shirted person is on the white structure, the jumpers are over the fence.

Now, check background: minimal, so just mention the grassy field, some trees, but maybe not necessary. The main focus is on the people's motions.

Also, camera: static? The video shows a fixed camera, no movement mentioned.

So, putting it all together.

First, describe the initial action: A person in a green shirt is upside down on a white wooden structure. Two individuals in dark clothing jump over a wooden fence. One jumper lands on the structure, while the other continues over. The green-shirted person then moves, and the first jumper steps down. The second jumper descends from the fence and moves toward the structure. People interact around the structure, with one person standing on it and others moving away. Camera is stationary, top-down? Wait, the video is outdoor, so probably eye-level or slightly angled, but the rules say minimal background. The camera perspective: since the video is a single frame, maybe static, no movement.

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

Multiple people (discrete solid objects) moving across an obstacle course via locomotion (climbing, jumping, balancing), with clear physical motion trajectories.

Static background elements (fences, trees, buildings) show no significant uniform shifting; no fire, water, smoke, or wind-driven motion observed.


A person in a blue top and dark shorts runs toward a sandpit, leaps into the air, and lands in the sand. Nearby, a man in a white jacket stands observing, while other individuals are positioned along the track and grassy area. The camera follows the runner’s motion, panning to capture the jump and landing sequence. Background elements include colorful flags and a blue structure, but focus remains on the runner’s movement and surrounding observers.

Multiple individuals are actively running across the track; their movement is due to locomotion and explicit physical forces (muscle contraction). Cones and equipment are static.

Static background elements (blue container, buildings, track) remain consistent across frames with no uniform shifting or fluid motion (fire, water, smoke, wind).


A bald man with a gray beard wearing a dark polo shirt holds a pink object near his face, moving it slightly. A young blonde girl sits at a cluttered table, initially facing away but then turns to face the man. The table has red and purple mugs, bottles, and containers; the background includes kitchen shelves and a refrigerator. The camera remains static.

A person (adult) displays hand movements (e.g., holding and manipulating objects), and a child exhibits subtle posture changes; both are solid, discrete objects with localized motion.

Background elements (shelves, cabinets, decorations) remain static across frames; no fluid motion (fire, water, smoke) or significant environmental movement observed.


A person wearing a black top, pink shorts, and red shoes is seen climbing a rope inside a gym. They begin by hanging from the rope, pull themselves upward to stand, and then swing back down while maintaining a grip. The camera remains stationary, capturing the motion from a fixed angle.

The person (a woman) is the discrete object. She is moving her body (arms, legs) and appears to be performing a physical activity (e.g., stretching, preparing to jump).

The background (gym wall, logo, equipment) is static and does not shift. No fluid or environmental motion (fire, water, wind) is present.


Multiple people are visible in the pool, with some actively swimming or moving through the water. Their motion is distinct and driven by locomotion (swimming), with clear bounding box tracking.

The background (blue walls, pool edges) shows no uniform shifting, indicating no camera panning or tilting. Water in the pool has minor ripples due to swimmer motion but is not the dominant environmental feature.


A shirtless man lies on a table as a woman in a pink sleeveless top touches his abdomen, moving her hands across his stomach. To his right, a woman in a floral shirt holds his leg, while a woman in a white top with a green microphone records the scene. A child stands near the background. The camera remains static, capturing the group around the man.

Discrete objects: The person in the pink top (applying substance to the patient's abdomen), the person in the checkered shirt (holding a tool), and the patient (receiving care). Motion involves hand movements and tool manipulation due to physical interaction.

No shifting background elements; walls and medical equipment remain stationary. No fire, water, smoke, or wind present.


A person in dark pants and a dark top, wearing black shoes, walks from the right side of the frame toward the left, passing office chairs and a desk. They briefly extend their right arm toward the desk before continuing their stride. The camera remains stationary at a low angle throughout the sequence, capturing the individual's lower body movement in an office setting with scattered items and furniture.

A person wearing dark pants and shoes is performing rhythmic leg movements (e.g., jumping, stepping) and arm motions. The person is the only discrete object with significant motion, moving within the frame against the static office background.

Background elements (desk, chairs, shelves) remain stationary with no fluid motion (fire, water, smoke, wind) observed. The environment is static office furniture without environmental fluid dynamics.


Two hands press a rectangular food item into a white bowl filled with light brown breadcrumbs, rotating it to achieve even coverage. They lift the coated item and place it onto a white plate.

Hands move a solid food item (likely a roll or log) through a bowl of breadcrumbs and then place it onto a plate; the motion involves deliberate physical interactions with the object.

The background consists of a static bowl, plate, and wooden surface with no shifting or fluid motion (e.g., no fire, water, smoke, or wind).


A pair of hands with polished nails and silver rings rests on a metal tin, then uses a black-handled knife to slice across the tin's surface from left to right; the hands shift position as the cutting action concludes, captured in a close-up, top-down perspective with minimal background.

The hands (with rings and painted nails) and a black object (likely a phone) are moving. The hands are pressing and moving the phone across a stack of money in a tin container.

The background (table) is static and shows no shifting. There are no fluid or environmental motions (fire, water, wind) present.


A brown paper bag and a white ceramic bowl rest on a red plaid fabric. A hand moves the bag toward the bowl, lifts it, and dips fingers into the bag, adjusting its position. The camera remains top-down and static throughout.

A hand (part of a person) is moving a brown paper bag, causing it to shift position on the table.

The red plaid tablecloth background is static, showing no shifting or fluid motion. No environmental phenomena (fire, water, smoke, wind) are present.


A woman in dark clothing stands on a black mat in a dimly lit indoor space, swinging a baton and shifting her stance; a person on a scooter remains stationary to her left near a door, while others observe from the background. The camera pans slightly, following the woman's movements.

A person (solid, distinct object) is performing physical exercises (e.g., lifting, bending) while standing on a mat; motion is due to explicit physical locomotion.

Background elements (walls, door, windows, posters) remain static with no significant shifts or fluid motion (fire, water, smoke, wind).


Two individuals stand in front of an orange backdrop with a circular wooden pattern; one wears a black shirt with a white logo and a black cap, the other a camouflage shirt holding a yellow microphone. The person in black leans in, covering the other’s mouth with their hand while they interact closely. The scene shifts to two new individuals, one in a colorful patterned shirt and another in a black shirt with a white cap, both standing before an orange background with visible flags. The person with the microphone holds it steady throughout. Camera remains mostly static with minimal cuts between scenes.

Two people are moving: the interviewer leans in to kiss the interviewee on the cheek, and then they move towards each other and the interviewee bends down. The scene then cuts to a new segment with two different people standing and talking.

The background (orange wall with circular pattern) is static and shows no fluid motion or shifting. There are no environmental effects like fire, water, or smoke.


A person in a camouflage-patterned jacket uses their hands to manipulate thin, branching objects, moving them toward a metallic device. The hands adjust the branches' positions in front of the tool, with the camera maintaining a close-up perspective and slight shake.

Discrete objects: person's hands manipulating wires and a cutting tool. The hands move to cut and handle the wires, showing explicit physical forces.

The background is a static camouflage pattern with no shifting or fluid motions (fire, water, smoke, wind).


A hand with a striped sleeve and bracelet uses a spoon to add and smooth white cream onto the top of a cake resting on a silver tray, which sits on a blue table. The camera maintains a top-down perspective with no movement.

A person's hand (part of a distinct human subject) is moving over the cake, likely attempting to cut or remove frosting.

Background elements (blue table, white bowl) are static and unchanging. No fluid or environmental motion (fire, water, smoke, wind) is present.


RAW CAPTION: Got it, let's break this down. The video shows a nighttime football field with a large scoreboard. First, there are a few people on the field. The main action: a player in a dark uniform kicks a ball towards the goalpost. Then, another player in a light green uniform runs after the ball. The ball is seen flying through the air, and the player in dark runs towards the goal. The camera seems to pan left as the players move. The background has empty stands and the bright scoreboard. Need to follow the rules: chronological order, focus on motion, describe appearance briefly, spatial relationships. Let's structure it.

First, the initial scene: players on field. Then the kick, ball flight, player chasing, another player running. The camera movement is a pan left. Background is empty stadium. Keep it concise.

Check the timestamps. At 0.0s, people are on field. Then the kick happens. The ball is kicked, then the player in dark runs towards the goal. The player in green runs to catch the ball? Wait, the second frame shows the ball in air, then the player in green runs. Wait, the description: "a player in dark uniform kicks the ball, then the ball is in air, then the player in green runs towards it. The other player in dark is running too. The camera pans left as the action unfolds.

So: A football player in dark clothing kicks a ball toward the goalpost. The ball arcs through the air as a player in light green uniform runs to pursue it, while another player in dark runs toward the goalpost. The camera pans left, tracking the players’ movements. The background features empty stadium seats and a bright scoreboard.

Wait, need to check the numbers. The video has a few players. Let's count: in the first frame, maybe two players: one kicking, one running. Then another player. So main subjects: three players? The caption should mention the number. Wait, rule b: briefly describe appearance and number. So "a player in dark uniform kicks... another player in green runs... a third player in dark moves toward the goal."

Wait, the first frame shows three people: left side a person standing, then a player in dark kicking, another in green running. Then the next frames: the kicker runs, the green player runs towards the ball. Let's parse the video sequence.

At [0.0], we see:

- Left: person standing (dark jacket, dark pants)
- Middle: player in dark uniform (shorts, dark top) kicking the ball (knee bent, leg extended)
- Right: player in light green uniform (jersey) running towards the ball
- Far right: another person (maybe in uniform)

Then [1.4s]: the ball is in the air, the kicker runs forward (toward the goal), the green player is now closer to the ball. The person on the left is still standing.

[2.5s]: the kicker is running, the green player is running to catch the ball. The ball is near the goalpost?

[3.6s]: the kicker is moving left (toward the goalpost), the green player is still chasing.

[4.7s]: the camera pans left, showing the kicker running left, the green player moving, the ball is still in play.

Wait, the caption needs to be chronological.

So step by step:

1. A football player in dark clothing kicks a ball toward the goalpost.
2. The ball arcs through the air while another player in light green uniform runs to pursue it.
3. A second player in dark clothing runs toward the goalpost, and the first player (kicker) continues moving toward the goal.
4. The camera pans left, following the players’ movements.
5. Background shows empty stadium seats and a bright scoreboard.

But need to be concise. Let's combine.

"A football player in dark clothing kicks a ball toward the goalpost. As the ball arcs through the air, a player in light green uniform runs to pursue it, while another player in dark clothing runs toward the goalpost. The camera pans left, tracking the players’ movements against the backdrop of empty stadium seats and a bright scoreboard."

Wait, check the rules. Exclude text recognition, named characters. So no need to mention specific jersey numbers. Also, background minimal unless essential. So the scoreboard is part of the background, essential for the setting.

Now, check the rules:

a) Motion in chronological order: kick, ball flight, players running.

b) Appearance: dark uniform (kicker), light green (pursuer), dark clothing (another player).

c) Spatial: player in green runs toward the ball (which is in air), the other player runs toward goal.

d) Camera: pans left.

e) Background: minimal, so empty seats

A player (discrete object) is seen running and kicking a ball toward the goalposts; the ball's trajectory is clearly driven by physical forces from the kick.

Stadium background (goalposts, stands) shows no uniform shifting or environmental fluid motion (e.g., fire, smoke, wind).


A man wearing a white shirt, dark vest, and multicolored striped headscarf stands outdoors before a utility pole. He raises his hands, retrieves a long rod from the pole, lifts it overhead, and looks upward while gripping it. The background features distant buildings and hills. The camera remains steady throughout.

A person is moving a long object (likely a pole or stick) through deliberate physical actions: raising, holding, and positioning it. The person's body and the object exhibit clear locomotion due to intentional force application.

The background (buildings, mountains, grass) is static with no shifting or fluid motion. No fire, water, smoke, or wind is visible; the environment appears calm and stable.


A crowd of people in casual clothing dances energetically under pulsating blue and green lights, swaying and raising arms in unison. As the camera moves through the densely packed group, dancers shift directions, some facing forward while others turn sideways. The handheld perspective follows the movement, exhibiting a slight shake, capturing the dynamic motion of the crowd in the dimly lit space.

Discrete solid objects (people) are moving via dancing locomotion, with visible interaction and displacement in the scene.

Background elements (venue lights, distant structures) show no uniform shifting; no dominant fire, water, or wind motion observed.


In a dimly lit church, a man in a dark suit holding a white bouquet stands in the foreground facing the altar. As the video progresses, he shifts slightly, while other individuals in the background walk toward the exit doors. The camera remains mostly steady with minor movement, capturing the gradual departure of people from the space.

Multiple people are moving through the hallway, exhibiting locomotion (walking) with distinct bounding box tracking possible. Motion is driven by human movement and is not fluid or environment-driven.

Background elements (walls, doors, windows) remain static with no fluid or environmental motion (e.g., fire, water, smoke, wind) observed. No uniform shifting of background structures.


Multiple riders on horses gallop across a grassy field during a polo match; riders wear green and dark blue jerseys while horses display varied colors including white, brown, and chestnut, with some horses carrying red saddlecloths. Riders maneuver dynamically, adjusting positions and extending mallets, as they move in different directions across the field. The camera maintains a high-angle, fixed perspective capturing the full expanse of the playing area. Background elements are minimal, focusing on the active motion of the riders and horses.

Discrete objects: Multiple riders on horses moving across the field. The motion is due to the horses' galloping and riders' maneuvers (locomotion and controlled movement).

The background (grassy field and distant fence) is stable with no fluid/environmental motion (fire, water, smoke, wind) and no uniform shifting. Therefore, ambient_environmental is not applicable.


RAW CAPTION: Got it, let's break this down. The video starts with a girl in a blue outfit sitting at a piano. She's initially facing the piano, then turns to look at the camera. The steps are: first, she's seated at the piano (legs crossed, maybe?), then turns her head to smile at the camera. Need to describe the motion chronologically.

Main subject: a girl in blue. Initial position: sitting at piano, facing it. Then turns head to the right (towards camera), smiles. Background: piano with sheet music, some items on top. But per rules, background minimal. Focus on motion: seated, turns to look at camera. Spatial: piano is behind her? Wait, she's at the piano, so piano is in front of her initially. Then she turns to face camera.

Check rules: chronological, motion of main subjects. So:

First, the girl sits at the piano, facing the instrument. Then she turns her head to the right, looking at the camera and smiling. Need to mention appearance: blue outfit, long dark hair. Number: one girl.

Camera: static? The video shows slight camera movement? Wait, the frames change from [0.0] to [5.0], the camera might be panning slightly, but the description in the video doesn't specify. Wait, the user says "conclude with camera perspective and movement". So check if camera moves. The video might be a static shot, but maybe slight movement. But the sample output might not have camera movement. Wait, the rules say "conclude with camera perspective and movement (e.g., top-down, pan left, slight shake)".

Looking at the video: the camera angle is fixed, maybe a slight pan. But the description should be minimal. Let's see: the girl is seated, turns, etc.

So putting it all together:

A girl with long dark hair, wearing a blue outfit, sits at a piano, facing the instrument. She turns her head to the right, smiling at the camera. The camera remains static, observing her from a slightly angled perspective.

Wait, need to check the rules: "Keep background descriptions minimal unless essential". The piano is essential here as it's the main object. So mention piano? But the main subject is the girl.

Wait, the main subject's motion: sitting at piano, then turning to look at camera. Appearance: blue outfit, long dark hair.

So:

A girl in a blue outfit, with long dark hair, sits at a wooden piano, facing the keys. She turns her head to the right, smiling toward the camera. The camera maintains a static perspective.

Wait, but the video starts with her facing the piano, then turns to look at camera. So chronological order: she is seated at piano (initially facing it), then turns her head to look at the camera.

Also, need to mention number: one girl.

Let's write:

A girl with long dark hair, wearing a blue outfit, sits at a piano, facing the instrument. She turns her head to the right, smiling directly at the camera. The camera remains static.

Check if all rules are met:

a) Motion and behavior: seated at piano, then turning head to look at camera. Chronological.

b) Appearance: blue outfit, long dark hair, one girl.

c) Spatial: piano in front of her initially, then she turns toward camera.

d) Camera: static (assuming no movement).

e) Background minimal: piano mentioned as essential.

f) No text, names, etc.

Yes.

Wait, but the video starts with her sitting at piano, then turning. So:

The girl is seated at a piano, facing the instrument with her legs crossed. She then turns her head to the right, smiling at the camera. The camera maintains a fixed position.

Wait, but need to be concise. Let's check the example output.

Wait, the user's example might not have the exact structure, but following the rules.

Another check: "Briefly describe their appearance and number (color, size, orientation)".

Appearance: blue outfit (color), long dark hair (color, size?), one girl.

Size: maybe not necessary, but "long dark hair" is okay.

So putting it all:

A girl with long dark hair, dressed in blue, sits at a piano facing the keys. She turns her head to the right, smiling toward the camera. The camera remains static throughout.

Yes. Let's confirm.

Initial state: sitting at piano, facing it. Action: turns head to right, smiles at camera. Camera: static.

That's chronological, mentions motion, appearance, spatial (facing keys, turning toward camera), camera static.

Yes. I think that's it.

Background elements (door, wall, furniture) are static and show no shifting or environmental motion. No fire, water, smoke, or wind present.


A man wearing a white shirt and blue jeans stands on a snow-covered pathway between two houses, initially facing away from the camera while holding an object in his right hand. He then turns to face the camera and takes a step back, moving slightly away from his starting position. The camera remains mostly stationary with minimal movement, capturing the man's motion against a backdrop of snow-dusted ground and residential buildings.

A single person (man) is walking toward the camera along the sidewalk.

The background elements (houses, bushes, sky, snow) are static with no significant fluid or wind motion observed. The environment appears calm and unchanging.


A man wearing a white t-shirt, dark shorts, and blue sneakers holds a dumbbell in his right hand and performs alternating lunges. He begins with his left leg extended forward and right leg back, then shifts his weight to extend his right leg forward while keeping his left leg back, repeating the motion. A red step platform is positioned to his left, and a squat rack with yellow weight plates stands to his right. The camera remains stationary throughout, capturing the exercise from a fixed side angle.

A person performs a lunge exercise, moving legs and body in a discrete, controlled manner with clear bounding box tracking.

Static gym background (weights, wall, floor) shows no uniform shifting; no fire, water, or wind motion present.


Three men sit around a round wooden table; the man in a white polo shirt on the left handles cards, the man in a light blue shirt in the middle raises his right arm, then lowers it and gestures toward the table, while the man in a white t-shirt on the right remains still. The camera stays fixed as the scene darkens.

Three individuals seated at a table are moving (e.g., gesturing, leaning forward, adjusting posture). These motions are discrete, solid object movements.

The wooden walls and table in the background are static; no fluid/environmental motion (fire, water, smoke, wind) is observed. The lighting change is a temporal effect, not an environmental motion.


A man in a red shirt and dark shorts bends down to lift a barbell loaded with yellow and blue weight plates from the ground, then raises it to his shoulders, and finally overhead while standing in a gym with weightlifting equipment in the background. The camera remains stationary throughout the sequence.

A person in a red shirt is performing a weightlifting exercise (likely a deadlift), moving the barbell through distinct phases (bending, lifting, standing). The barbell and the person are solid objects moving due to physical forces (muscle contraction, gravity).

Background elements (gym equipment, walls, floor) are static with no shifting or fluid motion (e.g., no fire, water, smoke, or wind-driven swaying).


A person in a black top dips a piece of chicken into a yellow liquid in a glass bowl. The chicken is lifted and manipulated over a white plate with additional chicken pieces. Nearby, a large glass dish containing shredded cheese sits to the left, alongside a small white bowl with powdered contents and another glass bowl with yellow mixture. The camera maintains a top-down perspective, focusing on the counter setup without significant movement.

The person's hands are actively moving a piece of chicken into a yellow liquid (likely egg) and manipulating it, representing discrete solid objects undergoing physical interaction.

Background elements (table, bowls, and walls) show no uniform shifting or fluid/environmental motion (e.g., no fire, water, or wind).


A seated girl with long hair holds a white fluffy dog in a room with pink shelves and hanging clothes. A second girl in a yellow top and patterned pants runs into the frame from the right, approaches the seated girl, takes the dog, and carries it away while the seated girl watches from behind. The camera remains static with slight movement throughout.

Two individuals and a dog exhibit physical interaction: the standing individual moves toward the seated person and pets the dog, causing the dog to shift position due to direct contact.

Background elements (furniture, shelves) remain static with no uniform shifting or fluid motion. No fire, water, or wind effects observed.


A person wearing dark long sleeves works inside an open black computer case with red accents, manipulating internal components with their hands.

The gray surface background remains static with no shifting or environmental fluid motion (fire, water, wind, etc.).


A white rectangular plate holds a pile of thinly sliced yellowish-white vegetables on a dark surface. A hand enters from the top right, placing a small white object onto the vegetables. The scene then transitions to a white screen.

A hand moves into the frame and places a piece of food onto the plate, then moves away. The plate and the sliced food remain stationary.

The background (wall and table) remains static throughout the video; no fluid/environmental motion is present.


A person in a light blue tank top, black pants, and a visor lies on artificial grass, then sits up into a cross-legged position facing a brick wall. The background includes stone steps and greenery. The camera remains close, slightly adjusting to follow the subject’s movement from lying to sitting.

A single person (discrete solid object) transitions from lying down to sitting upright, then to a cross-legged seated position. Motion is caused by the person's own locomotion (e.g., arm movements, body repositioning).

Static background elements (wooden wall, stone steps, plants) show no shifting or fluid motion. No fire, water, smoke, or wind-driven movement observed.


A person in a blue shirt and dark pants uses a long tool to manipulate a large, light-colored sack in a white basin, while another individual in a red and white striped shirt stands nearby in the background. The camera remains close to the basin, exhibiting slight shake as it focuses on the interaction.

Discrete objects include two people (one in blue shirt using a tool, another in red striped shirt observing), and objects inside a white container being manipulated by the tool.

Background elements (e.g., walls, distant structures) show no uniform shifting. No fire, water flow, or smoke motion observed.


Three individuals, two wearing red shirts and one in a blue shirt with black pants, stand on grass in front of a building. They hold white discs above their heads, then swing the discs downward in synchronized motion. The camera remains static with slight shake throughout the sequence.

The background consists of a static Sudoku grid on paper; no shifting background elements or fluid/environmental motion (fire, water, smoke, wind) is present.


RAW CAPTION: Got it, let's break this down. The video starts with a close-up of hands holding a small bottle, maybe a spice or seasoning. Then it cuts to a person in a kitchen wearing an apron. The person is standing at a counter with a brick wall in the background. They seem to be cooking, pouring something into a pan. The camera moves from the hands to the person's face, then to a wider shot of the kitchen. The background has shelves with kitchen items. Need to describe the sequence: close-up of hands, then the person (apron, kitchen setting), pouring into pan, then maybe stirring. Check the rules: chronological order, motion, appearance, spatial, camera movement.

First frame: hands holding a small bottle (maybe glass), dark sleeves. Second frame: person with short hair, light shirt, dark apron, in kitchen. Third: wider shot, brick wall, shelves, counter with utensils. Fourth: person pouring into pan. Fifth: close-up of pan with liquid. So the sequence is hands pouring, then person in kitchen, then wider shot, then pouring into pan, then pan close-up.

Now, concise paragraph. Start with the hands: "A person with dark sleeves holds a small glass bottle, shaking it as they pour liquid into a pan." Then the person: "They stand at a wooden counter in a kitchen with a brick wall and shelves, wearing a light-colored shirt and dark striped apron, pouring the liquid into the pan." Then camera moves: "The camera shifts from close-up to a wider shot of the kitchen setup before focusing back on the pan as the liquid flows."

Wait, need to follow the frames. Frame 0: close-up hands. Frame 1: person's face. Frame 2: person's body. Frame 3: wider kitchen. Frame 4: person pouring. Frame 5: pan close-up.

So the chronological order:

- Close-up of hands holding a small bottle, pouring liquid.

- Person in apron at counter, pouring.

- Wider shot of kitchen with brick wall, shelves, etc.

- Close-up of pan with liquid being poured.

Now, describe each step. Make sure to mention the person's appearance (apron, shirt), the action (pouring), spatial (kitchen, counter), camera movement (close-up to wide, then back to close-up).

Let's draft:

"A person with short dark hair and a dark striped apron over a light shirt stands at a wooden kitchen counter, pouring liquid from a small bottle into a pan. The camera transitions from a close-up of the hands holding the bottle to a wider shot showing the person in a kitchen with a brick wall and shelves filled with kitchenware. The person then continues pouring into the pan, and the camera focuses on the liquid flowing into the pan."

Check rules: motion and behavior chronological. Yes, hands pouring, then person in kitchen, wider shot, pouring into pan. Mention appearance (short dark hair, apron, light shirt), spatial (kitchen, brick wall, shelves), camera movement (close-up to wide, then focus on pan). Background minimal except essential (brick wall, shelves are essential for kitchen context).

Wait, frame 4 is person pouring, frame 5 is pan close-up. So the sequence is:

1. Hands pouring (close-up)

2. Person's face (frame 1)

3. Person's body in kitchen (frame 2)

4. Wider kitchen shot (frame 3)

5. Person pouring into pan (frame 4)

6. Pan close-up (frame 5)

Wait, the video has 6 frames? The user provided 0 to 5.

Wait the input is:

[0.0] close-up hands

[1.4] person's face

[2.5] person's body in kitchen (apron, shirt, counter)

[3.6] wider shot of kitchen (brick wall, shelves, counter with items)

[4.7] close-up of person pouring into pan

[5.0] close-up of pan with liquid

Ah, right. So the order is:

0: hands holding bottle, pouring

1: person's face (showing the person)

2: person standing at counter in kitchen

3: wider kitchen shot (brick wall, shelves, counter)

4: person pouring into pan (close-up)

5: pan with liquid

So the caption should be:

A person with short dark hair, wearing a light-colored shirt and dark striped apron, holds a small glass bottle and pours liquid into a pan. The camera shifts from a close-up of the hands to a medium shot of the person in a kitchen with a brick wall and shelves filled with kitchenware. The person continues pouring into the pan, and the camera focuses on the pan as the liquid flows.

Check rules: chronological

The background (door and wall) is static with no fluid motion (fire, water, smoke, wind).


RAW CAPTION: Okay, I need to create a concise, chronological paragraph for this video based on the rules provided. Let me start by analyzing the video frames.

First, the main subjects are a young boy and a horse. The boy is wearing a red and black checkered jacket, gray pants, and a dark blue cap. He's standing near a metal fence, holding onto the rails. The horse is brown with a white blaze on its face, and it's wearing a black hoof boot.

Looking at the sequence: in the first frame, the boy is holding the fence, looking at the horse. The horse is leaning over the fence, maybe eating or interacting with the boy. Then, the boy moves his hand up the fence, possibly trying to touch the horse. The horse's head moves towards him. The boy continues to interact, maybe petting or reaching towards the horse.

I need to describe this in chronological order. Start with the boy's position and actions. Mention his appearance briefly: red and black jacket, cap, gray pants. The horse is brown, with a white spot, wearing a black boot. The spatial relationship: boy is in front of the fence, horse is on the other side.

Check the background: there's grass, some trees, maybe another person in the distance, but the rules say to keep background minimal. So maybe just mention the grassy field and distant structures briefly.

Camera perspective: it seems like a steady shot, maybe slightly moving as the boy moves. The camera is at a medium shot, close to the boy and horse.

Need to avoid text recognition (like the cap says "BLUE" but we shouldn't mention that). Also, exclude stylistic analysis.

Putting it all together:

A young boy in a red and black checkered jacket and dark blue cap stands at a metal fence, holding the rails. He faces a brown horse with a white blaze and black hoof boots, which leans toward him. The boy extends his hand toward the horse, which moves its head closer as he gently touches its muzzle. The scene occurs in a grassy field with distant structures visible. The camera remains steady, capturing the interaction from a close, eye-level perspective.

Wait, check the rules again. Must be chronological. Let's see the frames: the boy starts by holding the fence, then reaches up, the horse moves its head, then the boy moves his hand. The caption should follow that order.

Also, mention the spatial relationship: the horse is on the other side of the fence. The boy is in front of the fence.

Make sure not to mention the background too much. "Grassy field with distant structures" is okay as it's minimal.

Check for exclusion of text: the cap says "BLUE" but the rules say exclude text recognition, so don't mention the cap's text.

Another check: "briefly describe their appearance and number". The boy is one person, horse is one animal. Their appearances: boy in checkered jacket, cap, gray pants. Horse brown, white blaze, black boots.

Camera: steady, eye-level.

Wait, the output format requires the caption to be in a specific tag. So the final output should be:

<caption_output>...<caption_output>

Let me rephrase:

A young boy in a red and black checkered jacket and dark blue cap stands at a metal fence, holding the rails. He faces a brown horse with a white blaze and black hoof boots, which leans toward him. The boy extends his hand toward the horse, gently touching its muzzle as the horse moves its head closer. The scene occurs in a grassy field with distant structures visible. The camera remains steady, capturing the interaction from a close, eye-level perspective.

Check the rules again. Rule a: motion and behavior in chronological order. The boy holds the fence, extends hand, touches horse, horse moves. Yes, that's chronological.

Rule b: mention appearance briefly. Check.

Rule c: spatial relationships. Boy in front of fence, horse on other side. The boy is to the left or right? The video shows the boy on the right side of the fence, horse on the left. Wait, in the frames, the boy is on the outside of the fence, so the horse is inside. So the boy is standing outside the fence, facing the horse which is inside. So the spatial relationship: boy is outside the fence, horse is on the other side.

In the description, should say the boy stands at the fence facing the horse, which is on the other side.

So revise:

A young boy in a red and black checkered jacket and dark blue cap stands outside a metal fence, facing a brown horse with a white blaze and black hoof boots. The horse leans toward him, and the boy extends his hand to gently touch the horse’s muzzle. The horse moves its head closer as he reaches. The

The child is moving arms and body slightly while interacting with the horse; the horse is moving its head to eat.

The background (fence, grass, trees) is stable with no shifting or environmental fluids (fire, water, smoke, wind) observed.


RAW CAPTION: Got it, let's tackle this caption. First, the main subject is a beekeeper. They're wearing a beige beekeeping suit with a veil and a hat. The video shows them interacting with beehives.

Looking at the sequence: in the first frame, they're near a hive. Then, they handle a hive component—probably a frame. The action is them opening or inspecting the hive. The background has grass, trees, and other beehives. The camera is static, maybe a window view, so it's a fixed perspective looking out.

Need to describe chronologically: the beekeeper (beige suit, veil) approaches a hive, adjusts or opens it, maybe uses a tool (like a smoker? but the tool is red). Wait, in frame 3, they have a red tool. Then frame 4, they're working on the hive.

So the motion: beekeeper in beige protective gear (veil, hat, suit) is seen handling a beehive frame. They move their hands over the hive, possibly inspecting or working on it. Spatially, they're positioned next to the hive, with other hives nearby. Background is grassy area with trees. Camera is a steady view from outside, likely through a window, so static.

Keep it concise. Let's structure:

A beekeeper in a beige protective suit with a wide-brimmed hat and mesh veil inspects a beehive frame, using a red tool to adjust or open the hive. They work methodically near other hives in a grassy, wooded area. The camera captures the scene from a static, slightly elevated perspective through a window.

Wait, need to check rules. Exclude text, names. Focus on motion and behavior. Chronological order.

Start: beekeeper (appearance: beige suit, veil, hat) is handling a hive. Actions: moving hands, adjusting, using tool. Background: grass, trees, other hives. Camera: static, window view.

So:

A beekeeper wearing a beige protective suit with a mesh veil and wide-brimmed hat adjusts a beehive frame, using a red tool to manipulate it. They work methodically beside other hives in a grassy, wooded area. The camera maintains a static, top-down perspective through a window.

Check if chronological. The sequence shows them handling the hive, so starting with the beekeeper at the hive, then moving the frame. Yes.

Make sure minimal background, only essential. Grass and trees are essential as setting.

Okay, draft:

A beekeeper in a beige protective suit with a mesh veil and wide-brimmed hat adjusts a beehive frame, using a red tool to manipulate it. They work methodically beside other hives in a grassy, wooded area. The camera captures the scene from a static, window-side perspective.

Wait, "top-down" is mentioned in rules. Wait, the original video is viewed through a window, so maybe the camera is outside looking in? So the perspective is from outside, but the video shows the scene as if viewed from the window. So "static, window-view perspective" or "static, viewed through a window".

Let me check the frames: it's a video, probably recorded from inside the house looking out the window at the beekeeper outside. So the camera is inside, looking out the window. So the perspective is through a window, static.

So:

A beekeeper wearing a beige protective suit with a mesh veil and wide-brimmed hat adjusts a beehive frame, using a red tool to manipulate it. They work methodically beside other hives in a grassy, wooded area. The camera captures the scene from a static, indoor window perspective.

But rules say "conclude with the camera perspective and movement". So need to specify.

Original video: frames show the beekeeper outside, so the camera is inside, looking out the window. So camera is static, positioned inside the building, looking out through the window.

Thus:

A beekeeper in a beige protective suit with a mesh veil and wide-brimmed hat manipulates a beehive frame, using a red tool to adjust it while working beside other hives in a grassy, wooded area. The camera remains static, viewed through a window from the interior.

Check if all rules:

a) Motion: beekeeper manipulates frame, uses tool. Chronological: starts with handling the hive, then using the tool.

b) Appearance: beige suit, veil, hat.

c) Spatial: beside other hives, grassy area.

d) Camera: static, window interior perspective.

e) Background minimal: grassy wooded area.

f) No text, etc.

Okay, that works.
</think>

<caption_output>A beekeeper in a beige protective suit with a mesh veil and wide-brimmed hat adjusts a beehive frame,

A beekeeper in protective gear is moving their hands and body to handle a beehive frame; the frame itself is being manipulated by the beekeeper.

Background elements (grass, trees, hive structure) show no uniform shifting or fluid environmental motion (e.g., no wind-blown foliage, smoke, or water flow).


Four people play beach volleyball on a sandy court at night under bright lights. Two players stand on each side of the net; one player on the right side jumps to hit the ball while others adjust positions. After the hit, the player who struck the ball runs toward the center, followed by teammates. The camera remains stationary at a low angle near the net, capturing the action with minimal background details.

Discrete solid objects (people) are actively moving through locomotion (running, positioning) on the sandy beach.

Background elements (sandy beach, streetlights) show no uniform shifting or fluid motion; ambient environmental factors like wind or water are not dominant.


A gloved hand holds a wooden carving piece on a person’s light blue denim lap, with wood shavings scattered around. The hand uses a tool to carve, producing additional shavings that fall onto the lap. The camera maintains a close-up, static perspective focused on the carving process.

Discrete solid objects include a person's hands manipulating a wooden object, with visible carving shavings; motion consists of precise hand movements and object deformation due to physical carving forces.

Background elements (floor tiles) remain static with no uniform shifting or fluid/environmental motion (e.g., fire, water, smoke).


A boy in a red shirt and blue shorts runs toward a basketball hoop from the right, jumps to shoot the ball, lands, and then sprints away. The camera remains stationary, capturing the driveway, stone wall, and a house in the background.

A person in a red shirt is moving: dribbling a basketball, running, jumping, and shooting. This discrete object (person) exhibits locomotion and explicit physical actions.

The background elements (stone wall, houses, trees) show no significant uniform shifting, and there are no fluid/environmental motions (fire, water, smoke, strong wind) dominating the scene. Subtle tree sway is not dominant.


A woman in a teal floor-length gown with a green crown stands on a black platform, gesturing with her hands; she shifts position slightly as the camera pans left, revealing an audience seated and standing in the background of a spacious indoor venue.

The primary discrete object is a person (female performer in blue dress) on a raised platform; her arm movements and posture changes indicate locomotion/physical motion due to deliberate action.

Background elements (walls, seated audience) show minimal displacement; no fluid or environmental motion (fire, water, smoke) detected. Audience remains mostly static with occasional subtle shifts.


A person wearing a gray long-sleeve shirt over an orange vest and blue jeans uses both hands to manipulate a green fabric, threading a needle through it in a repetitive motion. The hands adjust the fabric and needle methodically while seated, with fallen autumn leaves visible in the background. The camera maintains a close-up, static perspective focused on the hands and fabric throughout the sequence.

A person is manipulating a small object (likely a cloth or bag) with their hands; the motion is deliberate and solid, consistent with discrete object physics.

The background consists of static fallen leaves with no fluid motion (fire, water, smoke) or uniform shifting, indicating no ambient_environmental or camera_motion dominance.


A child wearing an orange life vest and dark pants water skis across the wake of a boat, steadily progressing closer to the camera while maintaining balance on the skis. The camera follows the skier from behind, capturing their approach with a distant shoreline and trees visible in the background.

A single person in a red vest is moving across the ice surface, exhibiting controlled locomotion (likely walking or gliding) with clear bounding box tracking.

Background elements (distant trees, horizon) show no uniform shifting or fluid motion; ice surface has minor texture variations but no environmental fluids (water, smoke, fire) or wind-driven movement.


A person's right hand holds a black fishing rod with a red handle, casting the line into a calm lake. The hand reels the line in, moving the rod upward and downward, while the distant boat remains stationary on the water. The rod is positioned horizontally, extending toward the center of the lake, with green trees and hills visible in the background. The camera maintains a first-person perspective, slightly shaking as the hand manipulates the rod.

The fisherman's hand and the fishing rod are moving as the person reels in the line.

The water has gentle ripples, but they are not dominant; the background (trees, boat, mountains) is stationary. The dominant motion is the fishing action, not ambient environmental.


RAW CAPTION: Got it, let's tackle this captioning task. First, I need to understand the video sequence. The video starts with a person with red hair wearing a green and floral cardigan, facing away from the camera. Then the scene changes to the person seated at a table with a purple background, looking at the camera. Next, there's a close-up of hands knitting with black and white yarn. Then it cuts back to the person at the table.

So chronologically: first, the back view of the person (red hair, green cardigan) at the table. Then the front view, smiling. Then hands knitting, showing the yarn and needles. Then back to the front view with the table items. Background has plants and yarn balls, but keep it minimal. Camera moves: starts with medium shot (back), then medium shot front, close-up of hands, then medium shot front again.

Need to focus on motion: person turns to face camera, then hands move to knit, then back to facing camera. Mention appearance: red hair, green cardigan, golden accents. Objects: yarn balls (white, blue, green), knitting needles, black and white sock.

Wait, the rules say to focus on motion and behavior in chronological order. So first, the person is seen from behind (red hair, green cardigan), then turns to face the camera, then the camera zooms in on hands knitting, then returns to the person at the table. Background elements: purple wall, plants, yarn balls on shelves. But keep background minimal.

Let's structure the paragraph:

The video opens with a person with short red hair and a green patterned cardigan seated at a table, facing away from the camera. The scene transitions to the person turning to face the camera, smiling, with a purple backdrop and knitting supplies including yarn balls and a partially knitted item visible on the table. The camera then focuses on the person's hands manipulating black and white yarn with knitting needles, forming a zigzag pattern. Finally, the view returns to the person seated at the table, maintaining a medium shot with the same background elements. Camera movement includes a shift from rear to front view, a close-up on the hands, and a return to the medium shot.

Check rules: a) chronological motion - yes. b) appearance: red hair, green cardigan, hands with rings. c) spatial: hands in front of the person. d) camera: starts medium (rear), then front, close-up, then front. e) background minimal (purple wall, yarn balls but not detailed). f) no text. g) no reasoning.

Wait, in the first frame, the person is facing away. Then second frame, front view. Third frame (close-up of hands). Then back to front. So:

A person with short red hair, wearing a green and floral cardigan, is initially seated with their back to the camera at a table with purple background. The person turns to face the camera, displaying a smile, with yarn balls and a knitted item on the table. The camera then cuts to a close-up of the person's hands knitting black and white yarn with wooden needles, creating a zigzag pattern. The shot returns to the person seated at the table, facing forward, with the same background elements visible.

Check for conciseness. Let's make it shorter. Maybe: A person with short red hair in a green cardigan is seated at a table, initially facing away from the camera with purple background. They turn to face the camera, smiling, as yarn balls and a knitted item remain on the table. The camera then focuses on the person's hands knitting black and white yarn with needles, forming a zigzag pattern, before returning to a medium shot of the person seated at the table.

Yes, that's better. Now check all rules:

a) Motion: facing away → turning to face → hands knitting → returning to seated. Chronological.

b) Appearance: short red hair, green cardigan (and in hands: rings, but maybe not necessary? Wait, in the video, hands have rings. But the rules say "briefly describe appearance and number". So "a person with short red hair and green cardigan; hands with rings". But maybe concise.

c) Spatial: hands in front of the person.

d) Camera perspective: initial medium shot (rear), then medium (front), close-up, then medium (front).

e) Background minimal: purple background, but not detailed.

f) No text.

So revised caption:

A person with short red hair and a green cardigan is seated at a table, initially facing away from the camera against a purple backdrop. They turn to face the camera, smiling, with yarn balls and a knitted item on the table. The camera then zooms to a close-up of the person’s hands knitting black and white yarn with wooden needles, creating

A person's hands are actively manipulating yarn and knitting needles, demonstrating discrete solid object movement.

Purple wall and shelves remain static; no fluid/environmental motion (fire, water, smoke, wind) observed.


A young girl in a green coat, pink pants, and a pink-and-white striped knit hat walks along a snow-covered path while holding an orange plastic shovel. She turns toward a metal railing, lifts the shovel to her side, and extends it forward to deposit snow over the railing. The camera follows her movement with a slight pan right, capturing her from behind and side as she approaches the railing.

Child (solid object) is moving via locomotion while interacting with an orange snow shovel; shovel motion is directly caused by child's physical actions.

Background elements (trees, bushes, fence, snow-covered ground) show no significant shifting or fluid motion. Minimal tree sway observed, but not dominant.

RAW CAPTION: Got it, let's see. The video shows a person doing a discus throw. First, the person is in a circular area, probably a throwing circle. They start with one leg extended, then rotate, swinging the discus. Let's break down the steps.

First frame: person is mid-throw, back to camera, leg up. Then they rotate, bringing the discus forward. Wait, the sequence is: at 0.0, they're in a stance with one leg lifted, then move to throw. Wait, looking at the frames: 0.0s is a kick, then 0.3s they extend the arm with discus. Wait, the video shows a person spinning in the throwing circle, typical discus throw motion. So the subject is a man, gray sweatshirt, black pants, red shoes, black beanie. He's in a concrete throwing circle, with a grassy field and trees in the background. The action is the throwing motion: he spins around the circle, rotating his body, then releases the discus.

Need to describe chronological order. Let's see:

- Starts with the person in the throwing circle, body angled, one leg lifted, preparing to throw.
- Then he rotates, extending his arm with the discus.
- Next, he continues the spin, moving his body in a circular motion.
- Finally, he releases the discus, arm extended forward.

Wait, the frames given: 0.0 to 0.5 seconds. Let's check each frame:

Frame 0.0: person is on the circle, right leg extended forward, left leg back, arm out to the side (maybe wind-up). Wait, no, the first frame (0.0) has the person with left leg forward, right leg back? Wait, maybe the movement is spinning. The motion is a discus throw, so the athlete spins around the circle to build momentum, then releases.

In the video sequence:

- At 0.0s, the athlete is in the throwing circle, body positioned for the throw, one leg lifted (right leg), arm extended back, discus in hand.
- At 0.3s, the athlete has swung the discus forward, body rotating, left leg now back, right leg lifted.
- At 0.6s, the athlete continues the rotation, arm extended, body moving in a circle.
- At 1.0s, the athlete has completed the spin, arm extended forward, about to release.
- At 1.3s, the athlete releases the discus.

Wait, but the frames provided are [0.0] to [0.5]s, but the user's video has frames up to 4.7s. Wait, the user's input shows [0.0] to [4.7]s. So the sequence is from 0.0 to 4.7 seconds.

Wait, the frames are:

[0.0] (first frame): person is in the circle, left leg forward, right leg back, arm extended to the right, discus in hand.

[0.3] (second frame): person has moved, right leg now forward, left leg back, discus in hand, arm extended.

Wait, maybe it's a sequence of the throw motion: starting with the athlete in the throwing circle, beginning to rotate, then accelerating the spin, then extending the arm to release the discus.

So the main subject is a person (male, wearing gray long-sleeve shirt, black pants, red sneakers, black beanie) performing a discus throw. He is in a concrete throwing circle, with a grassy field and trees in the background. The chronological motion: He begins by standing in the circle, one leg extended, body angled. Then he rotates his body in a circular motion, swinging his arm with the discus, gradually increasing speed as he spins. Finally, he extends his arm forward, releasing the discus.

Need to mention appearance: gray sweatshirt, black pants, red shoes, black beanie. Number: one person. Spatial: in the throwing circle, with grass and trees behind. Camera perspective: seems to be a fixed, side-on view (since it's showing the side of the thrower, the circle, etc.). No camera movement mentioned, probably static.

So the caption should be concise, chronological.

Let me structure it:

A man wearing a gray sweatshirt, black pants, red sneakers, and a black beanie stands in a concrete throwing circle, initiating a discus throw. He begins by extending one leg forward and swinging his arm backward, then rotates his body in a circular motion, bringing his arm forward to build momentum. As he completes the spin, he extends his arm horizontally, releasing the discus. The background features a grassy field and

A person in athletic attire performs a rotational throwing motion (likely discus or hammer throw), with the body moving through discrete, controlled rotational and translational phases.

Background elements (railing, trees, grass) are stationary; no fluid motion (fire, water, smoke) or significant wind-driven swaying is visible. Background shows consistent spatial alignment across frames.


A person's hands pick up green leafy vegetables from a wooden surface and place them into a glass dish containing layered ingredients like meat, tomatoes, and other vegetables. The hands move from the left side of the frame, adjusting the greens in the dish before stepping back. The dish rests on a folded green towel atop the wooden surface, with a large round vegetable positioned to the right. The camera remains stationary in a close-up view, focusing on the hands and dish throughout the sequence.

A person's hands are moving to pick and place fresh herb leaves onto a dish; the hands and herbs are discrete solid objects undergoing intentional physical manipulation.

No shifting background or fluid motion observed. Background elements (countertop, towel, kitchen wall) remain static throughout the sequence.

A woman with short light hair, wearing a white apron over a dark top, stands in a kitchen with stainless steel equipment and containers visible behind her. The scene then shifts to a dining area where three people are seated at a table: one in a red jacket, one in a green shirt, and one wearing a red cap. The person in the red jacket moves forward, the individual in the green shirt turns their head, and the person with the red cap remains seated. The camera transitions from a close-up of the woman to static shots of the dining area.

Discrete objects: People (e.g., person in red jacket seated, person in green jacket moving to sit, waiter in dark vest walking, and others) exhibit locomotion (walking, sitting, leaning) and social interaction (talking) with distinct bounding boxes.

The cafe interior background (walls, tables, chairs) remains static with no shifting or fluid motion (e.g., no fire, water, smoke, or wind effects). Ambient environmental elements are minimal and confined to normal indoor conditions.

Briefly check for shifting backgrounds or fluid/environmental motion (fire, water, wind).


In a dimly lit living room, a person seated on a couch (left) and another standing near a bookshelf (right) in a gray shirt and dark pants initiate movement. The standing person runs swiftly toward the camera, passing through the room past a brick wall, while a second person in a striped shirt bends over in the foreground. The camera follows the runner’s motion with a slight shake, shifting perspective across the room.

Two people: one person moves toward the table, bends down, and engages in physical interaction with another person who is seated on the floor. Their motion involves explicit physical forces (e.g., grappling, shifting positions).

Background elements (walls, doors, furniture) show no uniform shifting or fluid motion (e.g., no fire, water, smoke, wind).


RAW CAPTION: Got it, let's tackle this. First, the video shows two men. The main subjects are two men. Let's check their actions. The first man is playing a flute (or similar wind instrument), wearing a dark suit, glasses, has a watch. The second man is in a brown blazer, black turtleneck, has a clarinet strap, and he's moving his hands.

Chronological order: Start with the first frame. Both are standing. Left man plays instrument, right man gestures. Then the right man moves his hands, maybe raising a fist. So actions: left man consistently plays, right man makes hand movements.

Appearance: left man dark suit, checkered shirt, glasses, watch; right man brown blazer, black turtleneck, clarinet strap.

Spatial: left is in front of right (since he's on the left side of the frame).

Background: minimal, just the wall, Carnegie Hall text but per rule f, exclude text recognition. So don't mention Carnegie Hall.

Camera: static, no movement mentioned, so probably fixed shot.

Now, structure the caption. Start with the two men, their actions in order.

First, the two men stand in front of a wooden backdrop. The man on the left, dressed in a dark suit with a checkered shirt and glasses, holds a flute to his lips and plays it. The man on the right, wearing a brown blazer over a black turtleneck, gestures with his hands, moving them in various motions including raising his right fist. Throughout the sequence, the camera remains stationary, capturing their actions from a frontal perspective.

Wait, need to be concise. Let's check rules: concise, chronological paragraph.

"Two men stand side by side. The left man, in a dark suit with a checkered shirt and glasses, plays a flute. The right man, in a brown blazer and black turtleneck, gestures with his hands, moving them expressively. The camera remains fixed, capturing them from the front against a neutral backdrop."

But need to mention motion chronologically. The video starts with both in position, then the right man moves his hands. So:

"Two men stand in front of a wooden backdrop. The man on the left, dressed in a dark suit and checkered shirt, holds a flute to his lips and plays it continuously. The man on the right, in a brown blazer and black turtleneck, raises his right hand and makes expressive gestures. The camera stays stationary, capturing their actions from a frontal view."

Check if background is essential: the backdrop is wooden, but maybe "neutral backdrop" is okay, but rule e says minimal background. So maybe just "a neutral backdrop" or omit if not essential. The problem is that the backdrop is part of the scene, but rule e says minimal unless essential for understanding motion. Since motion is about their actions, maybe background can be "wooden wall" but maybe too much. Wait, the example in the problem has "CARNEGIE HALL" text, but rule f says exclude text recognition. So don't mention that. So background is just the wall, but since it's minimal, maybe just "a wooden wall" but the rules say minimal. Hmm. The original problem's image has a wooden wall, so maybe describe as "in front of a wooden wall" but the caption should be concise.

Wait, the rules: "Keep background descriptions minimal unless essential for understanding motion." Since the motion is their actions, maybe the background is just the setting, but not essential. Wait, maybe the caption can just mention the background as "a neutral backdrop" or "a wall" but the example given in the problem's image has a wall, but the caption should focus on motion. Let's see.

Another angle: the main focus is the two men's actions. So start with their positions: two men standing. Left man plays flute, right man gestures.

Let me try again:

"Two men stand side by side. The left man, wearing a dark suit and checkered shirt, holds a flute to his lips and plays it. The right man, dressed in a brown blazer over a black turtleneck, gestures with his hands, raising one fist and moving his arms. The camera remains fixed, capturing them from the front."

Yes, that's concise. Check for chronological: starts with both standing, then left plays, right gestures (with motion).

Check the rules:

a) Motion: left plays flute, right gestures. Correct.

b) Appearance: described (dark suit, checkered, brown blazer, black turtleneck). Number: two men.

c) Spatial: left and right.

d) Camera: fixed, frontal.

e) Background: minimal, only mentioned as side by side, so maybe the wall is implied but not described. Wait, the

Two individuals: one playing a harmonica with hand and head movements, and the other making gestures. Their motions are due to intentional physical actions (locomotion/gestures).
