RAW CAPTION: Got it, let's tackle this. First, I need to describe the video chronologically. The video starts with a person in a red shirt and black pants on a basketball court. Wait, no, the first frame shows two people: one in red and white, another in red. Wait, the video is of a gym. Let's check the frames.

In frame 0, two people are near the center. One is in red and white (maybe a soccer or hockey stick?), the other in red. Then in frame 1, the person in red is moving, maybe dribbling a ball. Wait, the action: the main subject is a person in red and white (maybe a goalkeeper?) or a player. Wait, the second frame shows a person in red running towards the other person. Wait, the video shows a person in red (maybe a soccer player) with a ball, moving across the gym. Then there's another person in the background.

Wait, let's parse the timestamps:

Frame 0: Two people near the center. One in red and white (maybe a sports uniform), another in red. The person in red is handling a ball (maybe a hockey stick? No, it's a gym, maybe a soccer ball? Wait, the court is a gym with basketball hoops. The person is holding a stick, like a lacrosse stick? Or a hockey stick. Wait, the video is from a gym, so maybe floorball or something.

Wait, the key is to follow chronological order. The first action: a person in red (maybe the main subject) is on the gym floor. Then moves towards the other person. Let's list the actions:

At the start, a person in red and black (maybe the outfit is red top, black pants) is near the center. Then they move towards the left side, passing another person in red. Wait, no: frame 0 shows two people close together. Then frame 1, the person in red is moving towards the left, the other person is in the background. Wait, the description in the video:

The video shows a gym with basketball hoops. There are two people: one in red (main subject) and another in the background. The main subject starts near the center, holding a ball (or a stick?), then runs across the gym towards the left side, passing by another person. Then the camera follows the movement.

Wait, the task is to describe motion and behavior in chronological order. Let's see:

- Initial frame: Person in red shirt and black pants (small, standing) is near the center of the gym, holding a ball or stick. Another person in red is nearby.

- Then, the person moves to the right (or left?), runs across the gym. The video shows them moving from left to right, passing another person.

Wait, the frames:

Frame 0: two people near the center, one in red and white, one in red.

Frame 1: person in red is moving towards the left, the other person is in the background.

Frame 2: person in red is running towards the left side of the gym.

Frame 3: person is now near the basketball hoop area (left side), moving left.

Frame 4: person is in the left part of the gym, moving left, near the wall with an American flag.

Frame 5: person has moved further left, near the wall.

So the main subject is a person in red (maybe red shirt, dark pants) moving across the gym from the center towards the left side, passing by another person. The camera follows this movement, panning left.

Appearance: main subject is red shirt, black pants, medium size. Another person in the background, maybe in blue or red.

Spatial relationship: the main subject starts near the center, then moves to the left, passing the other person who is in the background.

Background: gym with yellow walls, blue padding, basketball hoops.

Camera: starts with a static shot, then pans left to follow the main subject.

So putting it all together chronologically:

A person in a red shirt and black pants begins near the center of a gymnasium, holding an object, then runs leftward across the court, passing another person in red. The camera pans left to follow the movement.

Wait, check the rules: minimal background. So background is gym, but don't describe too much. Focus on main subjects' motion.

Also, appearance: red shirt, black pants (size, orientation - medium, moving left).

Another person in the background (maybe red shirt, but not as focus).

So let's structure:

The video shows a person in a red shirt and black pants moving from the center toward the left side of a gymnasium court, passing another individual in red. The main subject runs across the court, while the camera pans left to track their motion.

Wait

The person in red (batting) and the ball (being hit) are the discrete objects moving due to explicit physical forces (the bat hitting the ball and the person running).

The background (walls, basketball hoops) is static and does not shift uniformly. There is no fluid or environmental motion (fire, water, wind) present.


RAW CAPTION: Got it, let's tackle this video captioning task. First, I need to follow all the rules. The video shows a woman in an eyewear store. Let's break down the sequence.

At the start [0.0], there's a woman with long dark hair, wearing a headband and glasses. A person's hand adjusts her glasses. Then, she turns her head slightly, looking to the side. The background has shelves with eyewear and price tags. Then another person, a man in a suit, enters the frame, and a woman in a black shirt appears. The camera seems to move a bit, capturing their interactions.

Need to focus on motions: first, someone adjusts her glasses; she looks around; then a man and another woman join. Mention appearance: woman with headband, glasses; man in suit; woman in black shirt. Spatial: woman in front, man enters from left, another woman on right. Background minimal. Camera perspective: maybe a medium shot, slight movement as people move.

Wait, the rules say exclude text recognition, so ignore the text on screen. Focus on actions. So step by step:

- Initial frame: woman with headband and glasses, someone's hand adjusts her glasses.
- She then turns her head, maybe looks to the side.
- Then a man in a suit comes into view from the left, and another woman in black appears to the right.
- The camera remains steady but shifts slightly as people move.

Check the rules: chronological, motions of main subjects. Main subjects are the woman, then the man and other woman. Appearance: woman with dark hair, headband, glasses; man in suit; woman in black shirt. Spatial: woman in center, man on left, other woman on right. Camera movement: slight shake or pan? The video shows the camera capturing the scene as people move, so maybe a slight movement.

Make it concise. Let's structure:

A woman with long dark hair, wearing a headband and glasses, is seated in front of a store display with shelves of eyewear. A hand adjusts her glasses; she then turns her head to the side. A man in a dark suit and blue shirt enters from the left, and another woman in a black shirt joins from the right. The camera captures the interactions with slight movement as the individuals shift positions.

Wait, check for excluding text: yes, no mention of the text on screen. Mention spatial: woman in front, man on left, woman on right. Appearance: describe each. Chronological order: first adjustment, then turning, then others entering.

Let me refine:

A woman with long dark hair, wearing a headband and glasses, has her glasses adjusted by a hand; she then turns her head to the side. A man in a dark suit and blue shirt appears from the left, and another woman in a black shirt joins from the right. The camera remains steady but slightly shifts as the individuals move within the frame.

Check if background is minimal: yes, shelves are mentioned but not detailed. Keep background minimal unless essential. The store display is essential for context (eyewear store), so maybe mention "in front of an eyewear store display" but since rule e says minimal, perhaps just "store display with shelves of eyewear" as needed.

Wait, rule e: minimal background. So maybe just "store display with shelves" as context.

Final check: chronological, motions, appearance, spatial, camera.

Another angle: first frame, woman's glasses adjusted, she looks around. Then man enters from left, woman in black from right. Camera movement: slight shake as people move.

So the caption should flow as:

A woman with long dark hair, wearing a headband and glasses, has her glasses adjusted by a hand; she turns her head to the side. A man in a dark suit enters from the left, and a woman in a black shirt appears from the right. The camera captures the scene with slight movement as the individuals shift positions in front of the store display.

Wait, "store display with shelves of eyewear" might be necessary for context. But rule e says minimal background. So maybe "in front of shelves with eyewear" is okay.

Wait, the initial frame shows "Mercado dos Óculos" which is the store name, but rule g says exclude text recognition. So don't mention the store name.

So:

A woman with long dark hair, wearing a headband and glasses, has her glasses adjusted by a hand; she then turns her head to the side. A man in a dark suit and blue shirt appears from the left, and another woman in a black shirt enters from the right. The camera captures the interactions with slight movement as the individuals shift positions in front of the store's eyewear display.

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

A woman with long dark hair, wearing a head

Three people (a woman adjusting glasses, then two others entering the frame) move via locomotion (walking); discrete solid objects with clear bounding box tracking.

Shelves and product displays remain static with no fluid motion (fire, water, smoke) or wind-driven environmental effects; background elements do not shift uniformly.


A woman in a silver dress stands with hands on hips in the center of a stage, flanked by a person in a white outfit holding a plate to her left near a blue circular structure and a man in a blue shirt to her right. The man in blue steps forward, extends his arm toward the woman, then turns to speak into a microphone as the camera shifts to a close-up of him, with another woman visible in the background near red curtains.

Three individuals (two men, one woman) move expressively—gesturing, shifting positions—indicating intentional locomotion or interaction.

Red curtains and background screen ("THE FAZ") remain stationary throughout; no fluid motion (fire, water, smoke) or wind effects observed.


A person in a white shirt and shorts approaches a large orange ball on a gym floor, jumps onto it, and rolls rightward toward a red platform, moving across the space as the camera slightly pans to track their motion.

A person performs acrobatic movements (handstands, jumps, balancing) while interacting with a large red ball; both the person and ball exhibit solid-object motion due to physical forces.

Background elements (walls, gym equipment, banners) remain stationary across frames; no fluid/environmental motion (fire, water, smoke, wind) is present.


Two women sit side by side on a couch; one wears a white crocheted sweater and the other a brown shirt, both manipulating a piece of yarn with their hands while working collaboratively. The background includes a chair and windows with blinds. The camera remains stationary throughout.

Two individuals are engaged in discrete hand movements, interacting with a small object (e.g., handling items or performing a task).

Background elements (windows, chair, couch) show no shifting or fluid motion; no fire, water, smoke, or wind is present.


In an indoor futsal game, a player in black shorts and shirt kicks a ball to an orange-shirted player. The orange player dribbles the ball while two black-shirted players chase from behind, and another orange player moves to the right. The green-shirted goalkeeper stands near the goal as the ball travels toward it. The camera pans left, following the players' movement across the court.

Briefly describe what discrete, solid objects are moving.

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


A man in a gray long-sleeve shirt stands against a green backdrop. He initially touches his right ear with his right hand, then shifts his head left while lowering his hand, raises his hand to his chin, turns his head to face the camera, and finally adjusts his posture with his hand near his chin. The camera remains static throughout.

The man in the gray shirt is making deliberate hand movements near his face (touching cheek, jaw, and moving hand away).

The background is a static green screen with no shifting or environmental effects. No fire, water, smoke, or wind present.


Hands manipulate a pink and patterned scrapbook on a grid surface, using scissors to cut a page section, then turning the book to adjust a photo and remove a strip of material; the camera remains stationary top-down.

Discrete objects in motion: the person's hands (cutting and arranging paper), scissors, scrapbook pages, and photograph.

The background is a static grid-patterned surface with no shifting or environmental effects (no fire, water, smoke, or wind).


A man in a light gray shirt, beige pants, and cap stands on a green mat, facing forward; a woman in a light pink shirt and jeans stands to his left. The man adjusts his stance, swings a golf club, and hits the ball. The scene occurs on a paved area with a wooden structure behind them, overlooking grassy terrain. The camera remains stationary throughout.

The golfer and golf club are moving due to the golfer's swing, and the golf ball is struck and moves (though not visible in all frames, the action is clear).

Background elements (wooden structure, paved area, grass) are static with no shifting or fluid motion (fire, water, wind).


A person wearing blue jeans and red/black gloves uses a blue and black power tool to cut a light-colored wooden board placed horizontally on a wooden pallet. The person moves the tool steadily along the board, generating sawdust on the pallet. The board remains fixed on the pallet throughout the action, with the person’s hands guiding the tool. The camera maintains a static perspective, focusing on the cutting motion from a frontal angle.

A person (wearing blue jeans and red gloves) is actively using a circular saw on wooden pallets; the saw blade and hand movements are distinct solid-object motions due to mechanical operation.

Background elements (railing, distant landscape) show no uniform shifting or fluid motion; no fire, water, or wind-driven phenomena observed.


A person in a white shirt and dark pants sits on a carpeted floor, holding a sheet of paper and inserting it into a black printer positioned in front of them. The printer has a black laptop placed on top, with its screen displaying a windowed interface. The person adjusts the paper within the printer’s tray. The camera remains stationary, capturing the scene from a fixed angle.

A person is handling cards and interacting with a device (likely a card reader); the hands and cards are moving in discrete motions due to the person's actions.

The background (table, laptop, and other stationary objects) is stable with no uniform shift, and there are no fluid or environmental motions (e.g., fire, water, wind) present.


A high-angle, static camera captures a construction site where three workers (one in red shirt, one in green, one in white) converge on a wooden structure; the red-shirted worker moves toward the structure from the right, the green-shirted worker follows closely, and the white-shirted worker remains near the structure’s base, with parked vehicles and construction materials visible in the background.

Discrete objects: multiple people walking across the parking lot (e.g., a person in red moving leftward at 0.7s, others near the building from 0.0-3.5s). Movement is locomotion-driven with clear bounding box tracking.

Background elements (buildings, parked vehicles, ground) remain stable with no uniform shifting or environmental fluid motion (fire, water, smoke, wind). The scene shows a calm parking lot with no significant ambient effects.


A child's hands, wearing blue shorts, manipulate colorful jigsaw puzzle pieces on a blue table; the right hand moves a blue-yellow piece toward the left, then positions it next to a light blue piece, while the left hand assists in alignment. The camera remains top-down with minimal movement, capturing the hands' actions against a tiled floor background with indistinct yellow and green objects.

Hands moving puzzle pieces on a blue board; discrete solid objects undergoing manipulation by explicit physical forces (hand movements).

Static background (tiled floor and yellow bag) with no fluid motion (fire, water, smoke, wind) detected.


A person in a purple jacket with a red collar manipulates a large dark gray fabric under a white sewing machine, pulling and repositioning it repeatedly to sew. The camera remains static, capturing the person's hands and the machine from a side angle.

A person in purple clothing operates a sewing machine, moving their hands and body to guide fabric through the machine. The sewing machine itself is stationary, but the fabric and the person's limbs exhibit discrete motion from manual manipulation.

Background elements (tables, chairs, room fixtures) show no uniform shifting or fluid motion. No fire, water, smoke, or wind is visible in the scene.


A person wearing a green shirt and khaki pants stands on a sunlit grassy park area, holding an object in their right hand. They swing their arm forward and release the object, then turn their body slightly to the left while maintaining their position. The camera remains stationary throughout, capturing the motion against a backdrop of trees and distant park features.

A person (discrete solid object) is performing actions: holding an object, throwing it, and bending down. The motion is due to the person's physical actions.

The background consists of static trees and grass with no significant wind-induced motion or fluid effects. No fire, water, or smoke is present.


A person in a brown shirt leans over a microscope, adjusting its components, while another person in a green shirt stands behind and moves slightly. The brown-shirted individual focuses on the microscope, occasionally shifting position, with the green-shirted person observing and adjusting their stance. The camera remains relatively close to the subjects, exhibiting a slight shake throughout the sequence, capturing their interactions in a laboratory setting with minimal background details visible.

Two people: one in a brown shirt interacting with equipment (turning head, moving body) and one in a green shirt moving away.

No shifting background; no environmental fluid motion (fire, water, wind, smoke).


RAW CAPTION: Got it, let's break this down. First, the video starts with a man in a light blue polo shirt working on a device. Then the camera cuts to a close-up of a hand placing a white object into a tray with a light inside. Wait, the rules say to focus on motion and behavior chronologically. So the sequence is: the man is at a table (first frame), then the hand is opening a device (second frame), and then placing a small object into the tray. Let's check the frames. Frame 0: man in blue shirt, handling something on a white surface. Frame 1: close-up of hand opening a lid (dark gray lid) on a device with a light inside (the tray has water or liquid, maybe). Frame 2-5: hand continues placing a small object (maybe a pellet or something) into the tray. Wait, the text "TRUFFAUT" is in the corner, but we exclude text recognition. So main subject is the hand and the object.

Chronological order: The video begins with a person in a light blue polo shirt interacting with a device. Then the camera shifts to a close-up of a hand opening the lid of a rectangular container with an internal light. The hand places a small object into the container.

Appearance: Hand is light-skinned, the container is dark gray with a white interior, internal light is bright white. The object being placed is small, white.

Spatial relationships: The hand is above the container. The container has the lid being opened, so the hand is moving the lid.

Camera perspective: Starts with a medium shot of the person, then close-up on the hand and container.

Background: Minimal, maybe the work area but not essential.

Now, write in concise paragraph. Avoid text, names, etc.

Let's draft: A person in a light blue polo shirt interacts with a device at a table. The camera then focuses on a close-up of a hand opening the lid of a dark gray container with a white interior and internal light, revealing a tray with liquid and a green object. The hand places a small white object into the tray.

Check rules: a) motion chronological (person interacts, then hand opens lid, places object). b) describe appearance (light blue shirt, dark gray container, white interior, small white object). c) spatial: hand above container, placing into tray. d) camera: starts medium shot, then close-up. e) background minimal. f) exclude text.

Make it concise. Maybe: A person in a light blue polo shirt works at a table with a device. The camera shifts to a close-up of a hand opening the lid of a dark gray container with a white interior and internal light, placing a small white object into the tray containing liquid and a green item.

Wait, the video shows the container with a light (probably a LED strip) along the top, and the hand is putting something in. The frames show the hand pressing down on the lid (first close-up), then opening it. Wait, the second frame (index 1) shows the lid being opened by the hand, then the hand places the object. Let me check the timestamps: frame 0: person at table. Frame 1: hand opening lid. Frame 2: hand continues opening lid. Frame 3: hand near container. Frame 4: hand holding object over container. Frame 5: object is placed into container.

So the sequence is: hand opens lid, then places object. The container has a light inside (so the tray is illuminated). The green object in the tray is part of the contents.

So final caption: A person in a light blue polo shirt interacts with a device at a table. The camera then shows a close-up of a hand opening the lid of a dark gray container with a white interior and internal LED light, followed by placing a small white object into the tray containing liquid and a green item.

Wait, but the rules say "concentrate on motion and behavior of main subjects in chronological order." The main subjects are the hand and the object. The person is in the first frame, but the main action is the hand. So maybe: A hand opens the lid of a dark gray container with a white interior and internal light, then places a small white object into the tray containing liquid and a green item.

Wait, but the first frame shows the person. But the rules say "primarily on motion and behavior of main subjects". The person is a main subject, but the action is the hand. Let's see. The user's example says "if the video shows a person, include their action". So the first frame has a person: "a person in a light blue polo shirt works at a table with a device." Then the next part is the hand.

So

A hand moves a thin object (stick) into the water, creating localized disturbances (bubbles and ripples) within the container.

The background elements (container walls, dark panel) are static. The water in the container shows minor movement (bubbles) caused by the discrete object interaction, but the dominant motion is not fluid-driven ambient motion.


An elderly person with white hair and a dark blue shirt dries a small light brown golden retriever puppy wrapped in a green and white striped towel, adjusting the towel to pat the puppy’s body while holding it close. The puppy remains still, nestled against the person. The camera stays stationary throughout.

A person (wearing a blue shirt and jeans) and a light brown dog are the discrete objects. The person's hands move the towel to dry the dog, and the dog remains mostly stationary while being wrapped in the towel.

Wooden cabinets and countertop in the background show no uniform shifting or fluid motion; no fire, water, or wind is present.


A person with long blonde hair and a white tank top stands against a wall with a decorative grapevine mural, holding a large purple cylindrical object. They manipulate the object by rotating and extending it outward, shifting its position in front of their body. The camera remains stationary, capturing the person from a frontal perspective.

The woman manipulates a purple cylindrical object with her hands, exhibiting deliberate motion consistent with physical handling (e.g., gripping, rotating, or positioning).

Background elements (wall and grapevine painting) show no shifting or fluid motion; static environment with no fire, water, or wind effects detected.


A person’s hands grip a large green watermelon with a red interior, using a knife to slice into it. The watermelon rests on a surface as the hands steady it while the knife cuts through the fruit. The camera maintains a close-up, static view throughout.

The watermelon is being cut by a knife held by a person. The person's hands move to hold and guide the knife, and the watermelon is rotated to facilitate cutting.

No shifting background or fluid/environmental motion observed; background elements (e.g., table, wall) are static and not shifting uniformly.


The video shows a person's hands rapidly tapping a round drum with a light brown head and red border, held between gray pants on a wooden floor. The camera maintains a top-down perspective throughout, focusing on the hands' motion.


A man in dark clothing and a cap drives a yellow snow blower forward across a snow-covered yard, passing a white house with a red roof and snow-laden bushes. The camera follows the vehicle’s movement, maintaining a consistent perspective as it clears snow and progresses along the yard.

A person operating a yellow lawn tractor moves forward through the snowy landscape. The tractor's motion is distinct and tracks the person's steering and propulsion.

Background elements (white house, snow-covered ground, trees) remain static and show no uniform shifting. No fire, water, smoke, or wind-driven fluid motion is visible.


RAW CAPTION: Got it, let's tackle this. First, the video shows a person lying down, probably in bed. Let's check the frames. The person has red hair, wearing a white shirt with black patterns. They're under a blanket, covered up to the chest maybe. In the first few frames, they're lying still, then maybe moving a bit. The background has a curtain with stars and white blinds. The camera is positioned low, close to the person, maybe a bit shaky. Let's list the motions: the person is lying down, then perhaps shifts position slightly, like moving their arm. Need to be chronological. So, the main subject is the person, appearance: red hair, white shirt with black design, lying on bed. Motion: starts lying still, then moves arm up, then shifts position. Background is minimal, just the curtain and blinds. Camera is close-up, slightly shaky. Let's put it all together.

Wait, the rules say focus on motion and behavior in chronological order. So start with what's happening first. The person is lying down, then moves their arm. Let's see the frames: in [0.0], person is lying, covered by blanket, arm up. Then in [1.4], same, then [2.5], they move their arm. Wait, maybe the person is adjusting their blanket or moving. Let's describe the sequence.

First, a person with red hair and a white shirt with black patterns lies on a bed, covered by a blanket. The person remains mostly still but slightly shifts their position, moving their arm upward and repositioning their body. The camera is positioned low, close to the person, capturing a slightly shaky perspective. Background includes a curtain with star patterns and white blinds, but focus is on the person's movements.

Check rules: a) motion and behavior chronological. So the person starts lying down, then moves arm. b) appearance: red hair, white shirt, black patterns. Number: one person. c) spatial relationships: lying on bed, blanket over, arm movement. d) camera: low, close, shaky. e) background minimal, but curtain and blinds are there, but maybe mention briefly? The problem says "minimal unless essential for understanding motion". Is the background essential? Maybe not, but in the video it's a bedroom, so maybe just note the curtain and blinds as part of the scene. Wait, the task says "Keep background descriptions minimal unless essential for understanding motion." So if the background isn't crucial, just mention it briefly. The background here is a curtain with stars and white blinds. But maybe in the caption, since it's a bedroom, but not sure. Let's see.

Final caption should be concise. Let's structure it:

A person with red hair and a white shirt with black patterns lies on a bed, covered by a blanket. The individual remains still but gradually moves their arm upward and shifts position slightly. The camera captures the scene from a low angle, close to the person, with slight shakiness. Background elements include a star-patterned curtain and white blinds.

Wait, but need to check the exact frames. The video is dark, so maybe the person is under covers. Let's check the frames:

Frame 0: person lying, arm up, covered by blanket.

Frame 1-4: same position but maybe slight movement.

So the motion is the person moving their arm. Let's make it chronological:

The person, with red hair and wearing a white shirt with black designs, lies on a bed, partially covered by a blanket. They move their arm upward and adjust their position slightly, remaining mostly still otherwise. The camera is positioned close to the person from a low angle, with slight shake, capturing the scene in a dimly lit room with a star-patterned curtain and white blinds in the background.

But the problem says "briefly describe their appearance and number (color, size, orientation)". So appearance: red hair, white shirt with black patterns (since it's a design), one person. Motion: lying down, moving arm. Background minimal, but the curtain is part of the scene. Wait, the rules say "Keep background descriptions minimal unless essential for understanding motion." So if the background isn't essential, maybe don't mention it. But in the video, the curtain and blinds are visible, but maybe they aren't essential for the motion. Hmm. Maybe better to omit the background unless needed. Let's see.

Original instruction: "Mention spatial relationships if relevant (e.g., in front of, to the left)." So spatial relationships: the person is on the bed, which is part of the room. But maybe the background is the wall with curtain.

Wait, the problem says "Exclude text recognition, named characters, or stylistic analysis." So no "Made with KINE MASTER" text.

Putting it all together:

A person with

The person (solid object) is moving their arm (e.g., lifting from under head), indicating discrete locomotion or physical movement.

No shifting background elements (walls, bed remain static); no fire, water, smoke, or wind visible. Background appears stationary.


A small child in a green long-sleeve shirt stands in front of a colorful pinball machine, then bends forward, lowering his head closer to the machine until his face is nearly resting on it. The camera remains mostly stationary with slight shifts as the child moves.

A young boy is moving his head and body while interacting with the pinball machine. His motion is due to his own physical actions (bending, leaning, looking).

The background (wall and floor) is static with no shifting. There are no fluids (fire, water, smoke) or wind effects present.


A baby in pink clothing crawls across a carpeted floor toward a red armchair, moving forward while an adult in dark pants and a gray jacket crouches nearby, observing the baby. The baby remains centered as it progresses toward the chair, with the adult staying in a stationary crouched position. The camera maintains a steady perspective with minimal movement, capturing the scene from a low angle.

A baby in pink clothing crawls forward on the floor, while an adult (sitting on the floor) makes subtle adjustments to their position (e.g., shifting legs, hand movements). Both objects exhibit discrete, localized motion without environmental interference.

The background (couch, floor, and wall) remains stationary with no uniform shifts or environmental fluid motion (e.g., smoke, water, wind). No dominant ambient elements are present.


tags.  Final caption: A person in a dark long-sleeve shirt and green pants stands on a leaf-covered path in a park, holding a small circular object. They raise their arms to throw the object forward, extending their hands in a smooth motion. A bicycle is positioned to their right, with a stone building visible behind them. The camera remains static. </think>  <caption_output>A person in a dark long-sleeve shirt and green pants stands on a leaf-covered ground in a park, holding a small circular object. They raise the object with both hands, then throw it forward with a sweeping arm motion. A bicycle is visible to the right, and a stone building appears in the background. The camera remains static throughout the sequence.


A man in a blue t-shirt and camouflage pants walks from a corner toward the camera, holding a yellow-handled tool. He stops near a metal tray and blue bucket on the floor, with a circular object nearby. The camera follows his movement, then shifts to a lower perspective focusing on the floor and tray.

A person (holding a mop and bucket) moves across the room, exhibiting locomotion (walking) and manipulating objects (mop, bucket).

Background elements (walls, window, baseboards) show no uniform shifting; no fire, water, smoke, or wind present to dominate the scene.


RAW CAPTION: Got it, let's see. The video shows a dog yawning. The dog is a beagle, brown and white, with floppy ears. It's yawning, mouth open, tongue out. Then there's a quick cut to another dog, maybe a black one, but it's a split second. The main action is the first dog yawning. Camera is close-up on the dog, steady. Background is minimal, just a light wall. Need to describe chronologically: the dog (beagle, brown and white, large ears) yawns, then a brief shot of another dog. Camera stays close-up, no movement. Wait, the video starts with the dog yawning, then maybe the split second shows the other dog. Let me check the frames. Frame 0 to 5: dog yawning. Then frame 5 has "5" maybe a split screen? Wait the user provided 5 frames: first 0, then 1-4 are the dog yawning, frame 5 is the split? Wait no, the user's input is: [0.0 second], [1.4], [2.5], [3.6], [4.7]. Wait the video clip is 5 frames (0 to 4.7 seconds). The main subject is the beagle, then in frame 5 maybe another dog? Wait the user's example input shows frame 0.0: dog yawning. Then 1.4-4.7: same dog yawning. Wait, the problem statement says "the provided video" with 5 frames. But in the user's input, the first frame is [0.0 seconds] with the dog yawning, then [1.4], [2.5], [3.6], [4.7], all showing the same dog yawning. Wait, but in the video, maybe there's a transition. Wait no, the user's example shows the dog yawning for multiple frames. Wait the caption needs to be chronological. So the dog (beagle, brown and white, large floppy ears) is shown yawning with its mouth open and tongue out. Then, in the last frame (4.7 seconds), maybe another dog appears? Wait no, the user's input says "Frame 5: A black dog appears briefly to the right of the beagle." Wait looking at the user's provided video: the [0.0] frame has the beagle, [1.4] to [4.7] the beagle continues yawning. Wait the user's input description is: "0.0 second] [1.4] [2.5] [3.6] [4.7] - The video shows a beagle yawning, then a black dog appears briefly to the right." Wait, no. Wait the user's provided video frames: the first frame (0.0) has the beagle, then 1.4 to 4.7 are the same dog yawning. But the user's problem statement says "in frame 5: A black dog appears briefly to the right of the beagle." Wait no, the user's input has "Frame 5: A black dog appears briefly to the right of the beagle." Wait no, the user's provided video description in the problem statement is: "You are an expert video captioner. Your task is to generate a concise, chronological paragraph describing the provided video." Then the video frames are: 0.0, 1.4, 2.5, 3.6, 4.7. Wait the user's input image shows a dog (beagle) yawning, and then in the next frames, maybe the same. Wait the actual video description: the first few seconds show a beagle yawning, then a split screen or transition where another dog appears. But according to the user's problem statement, the caption should exclude text recognition, named characters, etc. So focus on the action. Let's parse the frames. The first part is the beagle (brown and white, floppy ears) yawning with mouth open, tongue out. Then, in the sequence, a black dog appears briefly to the right. Wait, but in the 5 frames provided (0.0 to 4.7), is there a split? The user's initial input image shows the dog, then in frame 5 (maybe 4.7), the black dog appears. Wait the user's example output needs to be chronological. So the main subject is the beagle yawning, then the black dog appears briefly. Let's check: the video starts with the beagle (brown and white, large floppy ears, close-up) yawning (mouth open, tongue out). Then, a black dog appears briefly to the right of the beagle. Wait,

A dog is yawning, with visible motion in its mouth and head as it opens and closes its mouth, representing discrete solid object motion.

The background appears static with no shifting elements or environmental fluids (fire, water, wind). No ambient environmental motion detected.


A child’s hand, wearing pajamas with cartoon prints, points and gently moves along a row of colorful toy trains (red, green, blue, and other hues) arranged on a blue mat. The hand shifts from one train to the next, maintaining contact with the toy cars. The camera remains in a static top-down position, capturing the hand’s motion against the blue and striped fabric background.

A hand interacts with toy trains, moving them along a track; the trains are solid objects with motion due to explicit physical forces (hand manipulation).

Background elements (floor, blue mat) show no uniform shifting; no fire, water, smoke, or wind motion present.


A man in dark clothing carves a large, translucent ice sculpture shaped like a horse, using a tool to shape the ice's upper section. He shifts his position slightly while maintaining focus on the sculpture, which glows under a bright light source above. The scene is dimly lit, with minimal background details visible beyond the illuminated ice. The camera remains stationary, capturing the carving process from a frontal perspective.

A person is actively moving around an ice sculpture, using tools to grind or shape it, demonstrating discrete physical motion due to manual labor.

Background elements (walls, structures) show no uniform shifting; no fire, water, smoke, or wind-driven motion observed.


Three people lie on a checkered bed; one in a striped shirt and blue jeans is positioned at the head, while another in a pink top and blue jeans and a third in gray pants lie toward the foot. Over the sequence, the individual in the pink top shifts their arm slightly, adjusting their posture, while the others remain still. The bed is adjacent to a pink railing and a standing fan, with the camera maintaining a top-down perspective and slight shake.

A person on the bed exhibits slight positional changes (e.g., shifting posture), indicating solid object motion.

Background elements (bed frame, fan, wall) show no uniform shifting; no fire, water, or smoke detected.


A woman in a blue and purple outfit carries a tray with green and yellow items through a seated audience. She moves forward, stops to interact with a seated man and woman, handing items from the tray, then continues walking past them. The camera follows her movement with a slight pan to the right, maintaining a medium shot of her and the surrounding crowd.

A woman in a bikini (discrete object) moves through the crowd while distributing items; her motion is due to explicit locomotion (walking) and interaction with seated individuals.

The background consists of stadium seating and spectators, which show no uniform shifting or fluid environmental motion (e.g., no fire, water, or wind effects). Background elements (seats, walls) remain static relative to the frame.


A close-up of a person wearing a dark shirt with a green collar shows their lower face; a hand enters the frame from the right, moves toward the chin, and gently touches the chin area in a slow motion. The background is blurred and indistinct. The camera maintains a fixed close-up perspective throughout the sequence.

A human hand is moving near the mouth, exhibiting discrete motion through intentional gestures (e.g., touching or pointing).

The background consists of a static fabric (dark blue with green trim) and no visible fluid or environmental motion (fire, water, wind). Background elements do not shift uniformly.


A young boy wearing a white shirt and blue jeans stands on a grassy area near a golf green, holding a golf club. He adjusts his stance, swings the club back, follows through with the swing, and looks down at the golf ball after the motion. The background features a house with stairs and a stone wall. The camera remains static with minimal movement.

The child is moving (swinging golf club and walking) and the golf ball is displaced by the club impact.

The background (stone wall, trees, building) remains static with no uniform shifting. No significant fluid or fire motion; minimal grass sway from wind is present but not dominant.


A person in an orange shirt kneels beside a bed, holding a large black machete, then stands and lifts the object toward the camera. A second person remains motionless under a red blanket on the bed. The room contains scattered clothing, with a doorway leading to a rocky outdoor area. The camera maintains a static perspective with slight shake.

A person sitting on the floor moves a curved tool (e.g., scythe) in a circular motion; the tool and person exhibit explicit physical motion due to hand/body movement.

Static stone wall and hanging clothes in the background show no shifting or fluid motion; no fire, water, smoke, or wind effects dominate the scene.


A man in a gray t-shirt drinks from a glass, lowers it, and holds a clipboard and pen while turning away from a wooden fence. He walks toward the fence’s corner, with the camera panning left and exhibiting a slight shake.

The man moves his arms (drinking, holding a lighter), the lighter produces a brief fire burst, and the man shifts position relative to the fence.

The wooden fence and surrounding static elements (trees, ground) show no uniform shifting or fluid environmental motion (fire, water, wind). The fire from the lighter is a transient effect not dominating the scene.


RAW CAPTION: Okay, let's tackle this video captioning task. First, I need to understand what the user is asking for. They provided a video clip and want a concise, chronological paragraph following specific rules.

Looking at the video frames, there's a person in a bedroom. The main subject is a person wearing a white shirt and black pants. They're moving their arms and legs in a dance-like motion. The background has a bed with white sheets, a door, and some furniture. The camera seems stationary, maybe a bit shaky.

I need to focus on the motion chronologically. The person starts with arms raised, then moves them down, steps side to side. The description should mention their appearance briefly: white shirt, black pants. Spatial relationships—like the bed to the right, door in the background. The camera is probably fixed but slightly shaky. Background details are minimal unless essential. No text or names to include.

Wait, the rules say to exclude text recognition and named characters, so just describe the actions. Let me structure it step by step. Start with the person's position and motion, mention their clothing, then the background elements only if necessary. Camera perspective is static with a slight shake.

Check the output format: must be in <caption_output> tags, concise paragraph, chronological. Avoid any markdown. Let me draft:

A person in a white shirt and black pants stands in a bedroom, moving their arms and legs rhythmically. They raise both arms above their head, then swing them down while stepping side to side, maintaining a wide stance. The bed with white bedding is visible to the right, and a closed door is in the background. The camera remains stationary but slightly shaky.

Wait, does it mention the chronological order? The motion starts with arms up, then swinging down, stepping. The first frame shows arms up, then moving. So the sequence is: raises arms, then moves them down, steps side to side. The description should reflect that order. Also, the person is in front of the bed. Make sure not to include background unless essential. Maybe the bed and door are just part of the setting but not crucial for motion. Hmm, the user says "minimal unless essential for understanding motion". Since the person is dancing in the room, maybe the bed is part of the background context but not directly affecting the motion. However, the rules say to mention spatial relationships if relevant. Maybe just say "in front of the bed" or "with the bed to the right".

Let me check again. The example in the rules: "Mention spatial relationships if relevant (e.g., in front of, to the left)." So if the bed is to the right of the person, that's relevant for context.

Putting it all together: A person wearing a white shirt and black pants dances in a bedroom, moving their arms in wide, rhythmic motions while stepping side to side. They raise both arms above their head, then lower them, continuing the movement with legs spread. The bed with white bedding is visible to the right, and a closed door is in the background. The camera remains static but exhibits slight shaking.

Wait, the user wants the caption to be a single paragraph, chronological. The movement starts with arms up, then the steps. Make sure it's in order. Also, keep it concise. Let me check the rules again: "concise, chronological paragraph describing the provided video." So each action in the order they happen.

Original video frames: starts with arms up, then steps out, arms moving. So:

The individual in a white shirt and black pants begins by raising both arms above their head, then extends them outward while stepping side to side. They maintain a wide stance, swinging arms in a rhythmic motion. The bed with white bedding is positioned to the right, and a closed door is visible in the background. The camera remains stationary with minimal shake.

Hmm, "maintain a wide stance" might be redundant since they're stepping side to side. Maybe "steps side to side with arms raised and lowered". Let me see the actual frames: the person starts with arms up (frame 0), then moves arms down (frame 1), then steps left (frame 2), right (frame 3), etc. Wait, the frames go from 0 to 5. In frame 0, arms up, frame 1 arms up, frame 2 arms moving, frame 3 arms up again. Wait, the user provided the frames as:

[0.0] person with arms raised.

[0.3] arms still up.

[1.4] arms up, legs apart.

[2.5] arms extended outward.

[3.6] arms up.

[4.7] arms down.

So the motion is: starting with arms up, then maybe moving arms down. Wait, the sequence shows the person moving their arms in a swinging motion,

A person (solid, distinct object) performs jumping jacks with clear locomotion: vertical jumps, leg spreads, and arm movements driven by physical effort.

Background elements (bed, door, walls) remain stationary with no shifting or fluid motion (e.g., smoke, wind). No ambient environmental phenomena observed.


RAW CAPTION: Got it, let's tackle this. First, the video shows a person with a sack over their head, right? Then there's another person, maybe a shirtless man. The main subject is the one with the sack. Let's break down the timestamps.

At 0.0, the person with the sack is in the frame, maybe turning. Then the sack moves, and a knife appears? Wait, no, the video description says "a knife" but in the frames, it's a blade coming from the right. Let's check the frames:

Frame 0: person with sack, dark background, maybe a shadow on the left.

Frame 1: same person, sack on head, moving? Maybe turning.

Frame 2: the blade (knife) appears from the right, approaching.

Frame 3: blade is closer, person with sack is facing the knife.

Frame 4: the knife is near the sack, maybe threatening or cutting?

Wait, the main subject is the person with the sack. The second person is partially visible at the start, then maybe leaves. Wait, the first frame has a shirtless man on the right, then in subsequent frames, he's not there. Wait, the user's input shows the video frames: in frame 0, there's a shirtless man on the right (partially visible), then the focus is on the person with the sack.

So the sequence:

- Start: Person with sack over head (tan sack, face visible inside the sack) is standing, maybe turning. A shirtless man is partially on the right.

- Then, the person with the sack moves slightly, and a knife (blade) enters from the right, moving towards the sack.

- The knife gets closer, the person with the sack's head (sack) is being approached by the knife.

- The camera seems to zoom in on the sack and the knife.

Background is a plain gray wall. Minimal background.

Now, rules: focus on motion and behavior in chronological order.

Main subjects: person with sack (sack on head, tan, face partially visible), and the knife.

First, the person with the sack is in the frame, then a knife appears from the right, moving towards the sack. The sack is on the person's head, they might be turning or moving slightly.

Wait, the frames: frame 0, person with sack on left, shirtless man on right. Frame 1: the sack person is still there, but the man on right is less visible. Frame 2: the knife appears from right. Frame 3: knife is closer, person with sack is now facing the knife. Frame 4: knife is near the sack, perhaps about to touch.

So the motion is: the person with the sack is standing, then a knife is introduced from the right, moving towards the sack. The person might be turning or reacting.

Wait, in frame 2, the knife is on the right, approaching. Frame 3, knife is closer, the sack is in the center, the knife is coming in from the right. Frame 4, knife is even closer, maybe the sack is being threatened.

So the sequence: a person wearing a tan sack over their head stands against a gray background. Another individual is partially visible on the right, then exits. The person with the sack turns slightly, and a knife appears from the right, moving towards the sack. The knife approaches closer to the sack, which is held in place by the person. The camera zooms in on the sack and the approaching knife.

Now, check the rules:

- Motion: person with sack (turns slightly), knife (enters from right, moves towards sack).

- Appearance: sack is tan, person has face visible under sack (but maybe not detailed). Knife is metallic, long blade.

- Spatial: knife is to the right of the sack person initially, then approaches from the right.

- Background: gray wall, minimal.

- Conclude camera: maybe slight zoom in.

Let me structure it:

"The video shows a person wearing a tan sack over their head standing against a gray background. Initially, a shirtless individual is partially visible on the right, then exits. The sack-wearing person turns slightly as a metallic knife enters from the right, moving towards the sack. The knife approaches closer, nearly touching the sack, while the person remains stationary. The camera zooms in slightly on the sack and the approaching knife."

Wait, but need to check if "shirtless individual" is necessary? The rules say "mention spatial relationships if relevant". The initial frame has a shirtless man on the right, but maybe he's not the main subject. The main subject is the sack person. The other person might be a secondary element, but in the sequence, maybe they're present at the start.

Wait, the first frame: "a

A tool (resembling a needle) moves incrementally toward a stationary, cloth-covered object (likely a mannequin or statue), indicating discrete object interaction.

Static gray background with no shifting elements or environmental fluids (fire, water, smoke, wind).


A person's arm reaches into the frame from the left, interacting with a pile of scattered electronic debris on gravel ground near a brick wall. The arm picks up a black plastic component with visible internal circuitry, manipulates it briefly, and repositions it within the debris. The hand and arm remain the primary focus throughout, with no other subjects present. The camera maintains a static, ground-level perspective throughout the sequence.

A person's hand interacts with a black bag and broken pieces of material (possibly electronic debris), moving them with clear physical contact and manipulation.

The brick wall, hose, and concrete blocks in the background show no uniform shifting or fluid motion. No fire, water, or smoke is visible.


RAW CAPTION: Got it, let's break this down. The video shows a man in a gym. He's wearing a black shirt, dark shorts, and white sneakers. He's holding two dumbbells. The action is him doing a step-up exercise on a blue step platform on a black mat. He lifts his right leg up, steps onto the platform, then brings his left leg up to step onto it too. The gym has various equipment around: weights, benches, a blue exercise ball, etc. But we need to keep background minimal. The camera is static, right? Let's check the frames: the man is centered, no camera movement. So chronological order: he starts standing on one leg, steps up with the other, then the other leg. Wait, first frame he's holding dumbbells, step up with right leg, then left leg. Wait, the video shows him lifting one leg, then the other. So step-by-step: He stands on the mat, holds dumbbells, lifts his right leg to step onto the blue platform, then lowers it, then lifts left leg to step onto platform. The caption needs to be concise, chronological. Mention his appearance: black shirt, dark shorts, white sneakers, two dumbbells. Spatial: in a gym with equipment, but minimal. Camera is static, front view.

Let me draft: A man wearing a black shirt, dark shorts, and white sneakers holds two dumbbells and performs step-up exercises on a blue platform placed on a black mat in a gym. He lifts his right leg to step onto the platform, then lowers it, and repeats with his left leg. The camera remains stationary, capturing him from the front in a medium shot.

Wait, check rules: focus on motion and behavior chronologically. So the actions: first, he's standing on the mat, then steps up with right leg (so right leg lifts, steps onto platform), then steps up with left leg. So "a man... holds two dumbbells... lifts his right leg to step onto the blue platform... then lowers it... lifts left leg to step onto platform."

Also, background descriptions minimal: just mention "in a gym" but don't describe all equipment.

Camera: static, front view, medium shot.

Let me check the rules again. a) Motion chronologically: so the sequence of actions. b) Appearance: black shirt, dark shorts, white sneakers, two dumbbells. c) Spatial: on a blue platform on a black mat in a gym. d) Camera: stationary, front view. e) Background minimal: "in a gym" is okay, but no details. f) No text, names, etc.

So putting it all together:

A man in a black shirt, dark shorts, and white sneakers holds two dumbbells and performs step-up exercises on a blue platform atop a black mat in a gym. He lifts his right leg to step onto the platform, then lowers it, and repeats the motion with his left leg. The camera remains stationary, capturing the sequence from a front view.

Wait, check if the action is as per frames. The video shows: frame 0-5, he's lifting right leg, stepping up, then left. So maybe "steps up with right leg, then left leg."

Another version: A man dressed in a black shirt, dark shorts, and white sneakers holds two dumbbells while executing step-up movements on a blue platform on a black mat within a gym. He lifts his right leg to step onto the platform, lowers it, and then lifts his left leg to step onto the platform. The camera remains static, viewing him from the front.

Yes, that's concise. Make sure to mention the number of dumbbells (two), but the rules say "briefly describe their appearance and number (color, size, orientation)." So "two dumbbells" is okay. Wait, the dumbbells are dark, maybe black? The video shows black dumbbells. So "holds two black dumbbells." But the rules say "briefly describe", so maybe "holds two dumbbells" is sufficient unless color is important. The problem says "color, size, orientation", but the main subject is the man, so his appearance is black shirt, dark shorts, white sneakers. The dumbbells: maybe "two dark dumbbells" but maybe just "two dumbbells" is okay. Let's check the rules: "Focus primarily on the motion and behavior of main subjects (people/animals/objects) in chronological order. Briefly describe their appearance and number (color, size, orientation)."

So the main subject is the man, so his appearance: black shirt, dark shorts, white sneakers. The dumbbells are objects he's holding, so they are part of the main subject's actions. So maybe include the dumbb

A person (discrete solid object) is performing a squat exercise, moving up and down due to explicit physical locomotion.

The gym background (equipment, walls, floor) shows no shifting or uniform motion; no fluids (water, fire, smoke) or wind effects present.


A man in a white t-shirt sits on a couch with beige cushions, holding a baby in his lap. He holds a white bottle, positioning it near the baby's mouth; the baby, dressed in a striped outfit, begins drinking. The man leans down and kisses the baby on the forehead. The camera stays close to the subjects with slight movement, focusing on their interaction while the background includes a framed photo and a small vase on the couch.

Discrete solid objects: a person (white shirt) and a baby. The person adjusts their position and interacts with the baby (e.g., holding, possibly feeding), while the baby exhibits slight movement.

Static background elements (couch, cushions, wall) show no uniform shifting or fluid motion. No fire, water, smoke, or wind is visible.


A man in a red t-shirt and black shorts stands in a room with white walls, a cabinet to his left, a door, and a television to his right. He jumps and spins toward the camera, moving forward with visual sparkles, then steps backward and stops near the cabinet. The camera remains static with slight movement.

The person in the red shirt and black shorts is moving: running, jumping, kicking, and extending arms, which are physical locomotion actions.

The background elements (walls, door, cabinet, TV, bicycle) are static and show no uniform shifting. The bright light effects are visual overlays and not fluid/environmental motion (e.g., fire, water, smoke, wind).


In a fenced enclosure, several dark brown pigs gather near a wooden fence, with one lying on the ground while others stand and root in the dirt. As the video progresses, the pigs shift positions, with one moving toward the fence. The camera pans slightly to the right, maintaining a steady view of the animals.

Discrete solid objects (animals) are moving within the fenced enclosure through locomotion; their motion is tracked by bounding box shifts.

Background elements (fence, trees) show minimal uniform motion; subtle tree swaying suggests weak ambient wind, but not dominant fluid/environmental motion (no fire, water, or dense smoke).


Two individuals in white karate uniforms with black belts stand in a dojo with a green floor; the person on the left holds a black pad while the person on the right prepares to strike. The right individual steps forward, executing a high kick toward the pad held by the left person, which moves slightly in response. The camera remains static, capturing the interaction from a fixed perspective.

Two people in martial arts uniforms: one performs a high kick and acrobatic flip while the other maintains a defensive stance. Motions are distinct physical actions (kicking, flipping) with clear bounding box tracking.

Static background elements (walls, windows, floor) show no uniform shifting. No fire, water, smoke, or wind present; environment is controlled and indoor.


A pair of hands adjusts red Christmas-themed wrapping paper adorned with Santa Claus and snowman prints on a carpeted floor. The hands lift the paper to expose a white box beneath, then hold the paper upright, displaying the box. The background features a green children's book and black shoes. Camera maintains a top-down view with slight movement.

The person's hands manipulate the red wrapping paper and white box, causing discrete motion of solid objects through physical handling (smoothing, tearing, lifting).

The background (carpet, green book, scissors) remains static with no uniform shifting. No fluid/environmental motion (fire, water, wind) is observed.


The video begins with a close-up of a red and white striped fruit corer. A person wearing a red shirt holds the corer over a green apple placed on a wooden cutting board, surrounded by other apples. The person inserts the corer into the apple, extracting the core. The camera maintains a close-up perspective, shifting slightly to follow the coring motion.

Hands manipulating a green apple on a plate, performing slicing motion. The apple is a solid object moving due to explicit physical forces (manual cutting).

No shifting backgrounds or fluid/environmental motion (fire, water, wind) observed. The background elements (table, apples) remain static throughout the video segments.


A hand presses a button on a black, oval-shaped robotic vacuum cleaner, then adjusts the control panel. The device rests on a carpeted floor near wooden furniture. The camera maintains a close-up perspective, focusing on the hand's interaction with the vacuum's controls.

A hand is moving to press buttons on a black device (likely a remote control or similar).

Static background (wooden furniture and carpet) with no fluid motion (fire, water, smoke, wind) observed.


A gloved hand manipulates tools over a vibrant painting depicting greens, oranges, and browns on a flat surface, moving from right to left to adjust elements. The hand remains centered on the artwork, with a tiled floor visible beneath. The camera stays in a close-up perspective, slightly following the hand's motion.

Discrete solid objects (gloved hands, tweezers, and other tools) are moving as the person manipulates the artwork on the glass surface.

Background elements (tiled surface) show no uniform shifting; no fire, water, smoke, or wind present in the scene.


RAW CAPTION: Got it, let's tackle this. First, I need to describe the video chronologically. The main subjects are a bird and a human hand. Let's break down the frames.

Frame 0: A small bird with a blue-gray head, yellow belly, and black bib is perched on a human hand. The hand has seeds. Background has mossy logs and greenery. Then the bird flies away (frame 1-2), leaving the hand with seeds. Frame 3-4: The bird returns, now in a different position, maybe landing on the log? Wait, frame 3 shows the bird landing on the log, and frame 4 the hand is holding seeds again, bird is near the hand.

Wait, the sequence:

- Start: Bird is eating seeds from hand. Then the bird flies off (so frame 1, 2: bird is gone, hand with seeds). Then frame 3-4: bird comes back, lands on the log? Wait, in frame 3, the hand is holding seeds, and the bird is flying towards the hand. Frame 4: bird is close to the hand, maybe about to eat again.

Wait, let's check the frames:

0: Bird on hand, eating seeds. Hand with seeds.

1: Bird flies away, hand still there.

2: Same as 1, bird gone.

3: Hand with seeds, bird is flying towards the hand (maybe landing).

4: Bird is now near the hand, landing on it?

Wait, the video description:

[0.0] Bird is on hand, eating.

[1.4] Bird flies away, hand with seeds.

[2.5] Still bird gone, hand with seeds.

[3.6] Hand with seeds, bird flies towards hand (landing), and another bird is on the log.

Wait, frame 3.6: "a hand holding seeds and a bird approaching from the left" – no, the description says frame 4 (time 3.6) shows the hand holding seeds, and another bird is on the log. Wait, the user's input:

<0.3 seconds> [bird on hand, eating]

<1.4> [bird gone, hand with seeds]

<2.5> [hand with seeds, bird gone]

<3.6> [bird returning, hand holding seeds]

Wait, the user's input for the video segments:

Frame 0: bird on hand, eating.

Frame 1: bird flies away (hand with seeds).

Frame 2: hand with seeds (bird gone).

Frame 3: hand with seeds, bird flies towards hand (maybe landing).

Frame 4: bird is near the hand, landing.

Wait, the key is to track the bird's movement. Let's list the timeline:

- 0.0 seconds: A small bird (blue-gray head, yellow belly) perches on a human hand, pecking at seeds. Hand is open, holding seeds. Background has a mossy log.

- 0.3 seconds: The bird flies away from the hand, leaving the hand with seeds visible. Hand is still in the same position.

- 1.4 seconds: The bird is no longer present; hand holds seeds. Background remains with the log and greenery.

- 2.5 seconds: Same as previous (bird gone, hand with seeds).

- 3.6 seconds: The bird returns, flying towards the hand, while a second bird is visible on the log in the background.

- 4.7 seconds: The bird lands on the hand, pecking at the seeds.

Wait, the user's video description:

<0.3> [bird on hand, eating]

<1.4> [bird flies away, hand with seeds]

<2.5> [hand with seeds (bird gone)]

<3.6> [hand holding seeds, bird approaching from left? Or landing?]

Wait, the description says frame 3.6: "a hand holding seeds and a bird approaching from the left" – no, the actual text for frame 3.6 is:

"<3.6 seconds> a hand holding seeds and a bird approaching from the left" – no, let me check the original input:

The user provided:

<0.3 seconds> [bird on hand, eating]

<1.4 seconds> [bird flies away, hand with seeds]

<2.5 seconds> [hand with seeds, bird gone]

<3.6 seconds> [hand holding seeds, bird returning to land on the hand]

Wait, the original frames:

The video starts with a bird eating from a hand. Then the bird leaves, then comes back. Let's parse the frames as given:

0.0: Bird (blue-gray head, yellow belly) is perched on a human hand

The main bird flies away from the hand, then returns, and another bird lands on the rock. These are discrete solid objects moving due to their own locomotion.

The background includes a rock with moss and a calm stream. The water movement is minimal and not dominant; thus, ambient environmental motion is not the primary force.


RAW CAPTION: Got it, let's break this down. The video shows a person cutting a pineapple. First, the hand with a bracelet is holding the pineapple on a wooden cutting board. Then, they slice it. The slices are taken off the board. There's a plate with pineapple leaves and another empty plate in the background. The main action is the cutting and moving the slices. Need to describe the sequence: the hand cuts, lifts the slices, moves them. The background has plates but keep it minimal. Camera is probably a close-up, static? Wait, the instructions say camera perspective and movement. Let's check the rules. So chronological order: first, the hand cuts the pineapple, then lifts the slices, then places them somewhere? Wait, the video frames: [0.0] hand on pineapple, [1.4] cutting, [2.5] taking a slice, [3.6] holding up the slice, [4.7] placing the slice. So the action is: a hand with a bracelet uses a knife to cut a pineapple on a wooden board, lifts the sliced pieces, and moves them away from the board. The background has a plate with pineapple leaves and an empty plate. Camera is close-up, static? The video is a fixed shot showing the action. So the caption should be chronological, describe the motion of the hand and pineapple, mention the plates in the background minimally. Let's draft: A person's hand with a bracelet cuts a pineapple on a wooden cutting board, slices the fruit, lifts the cut pieces, and moves them away from the board. In the background, a plate with pineapple leaves and an empty plate sit on the wooden table. The camera maintains a close-up, static perspective throughout the sequence. Wait, need to check the rules. Rule f: exclude text recognition, named characters, stylistic analysis. So no "person's hand" but maybe "a hand"? Wait, the rules say "main subjects (people/animals/objects)". So the main subject is the hand (person), then the pineapple. So: A hand with a bracelet uses a knife to slice a pineapple on a wooden cutting board. The hand lifts the cut slices, moving them away from the board. In the background, a plate with pineapple leaves and an empty plate are visible on the wooden table. The camera remains in a close-up, static position throughout the sequence. Let's check if that's concise. Also, the video shows the pineapple being cut, then the slices are handled. The sequence is cutting, lifting slices, moving them. So the caption should cover that. Maybe: A hand with a bracelet cuts a pineapple on a wooden cutting board, then lifts and moves the sliced pieces away from the board. A plate with pineapple leaves and an empty plate are positioned to the right and left of the board, respectively, on the wooden table. The camera maintains a close-up, static view. Wait, but the background plates: in the first frame, the plate with leaves is behind the pineapple, and the empty plate is to the right. So maybe: To the right of the cutting board, an empty plate sits on the wooden table; behind the pineapple, a plate with pineapple leaves is visible. But rule e says background descriptions minimal. So maybe just mention the plates without details. Let's see. The key is to focus on the main motion. So: A hand with a bracelet slices a pineapple on a wooden cutting board, lifts the cut slices, and moves them away from the board. In the background, a plate with pineapple leaves and an empty plate are visible on the wooden table. The camera remains in a close-up, static perspective throughout. That seems to fit. Check the rules: a) motion and behavior in chronological order: slicing, lifting, moving. b) describe appearance: hand with bracelet, pineapple (yellow, with rind), cutting board (wooden), plates (white with blue rim, one with leaves). c) spatial relationships: hand and pineapple on board, plates in background (right and behind). d) camera: close-up, static. e) background minimal: just mention plates. f) no text, no named characters. g) no reasoning. So the final caption should be concise. Let's shorten: A hand with a bracelet slices a pineapple on a wooden cutting board, lifts the cut slices, and moves them away. An empty plate and a plate with pineapple leaves sit on the wooden table in the background. The camera maintains a close-up, static view. Wait, maybe "slices the pineapple into pieces" instead of "cut slices". Let's check the video: the hand cuts the pineapple, then lifts the pieces. So: A hand with a bracelet uses a knife to cut a pineapple on a wooden cutting board, lifting the sliced pieces and moving them away. In the background, an empty plate and a plate with pineapple leaves rest

Discrete objects: hands (performing cutting actions) and pineapple (being sliced). Solid objects moving due to physical forces (knife cutting pineapple).

Background elements (wooden table, plates, green food) are static with no uniform shifting or fluid motion (fire, water, wind). No environmental fluid dynamics observed.


Two colored cups (blue and green) sit on a reflective floor in front of window blinds. Hands enter the frame from both sides, holding an orange circular object and a white circular object with a star, moving them toward the camera before withdrawing. The camera remains static, capturing the scene from a low angle.

Two circular objects (one orange with text, one white with text) are held and moved by hands. The hands enter the frame, bring the objects close to the camera, and then move them away.

The background (blinds, table, cups) is static and unchanging. No fluid or environmental motions (fire, water, smoke, wind) are present.


A person with long dark hair and a dark shirt bends over a bed with white sheets, then leaps upward and lands on the bed, moving to adjust the bedding. The room contains a mirror, a lamp, and framed artwork on the wall. The camera remains stationary with minimal movement.

A human subject (discrete solid object) is actively moving, making the bed (adjusting pillows, pulling sheets, and repositioning bedding).

Background elements (mirror, framed picture, lamp) remain stationary throughout; no fire, water, smoke, or wind detected in the scene.


A person in a grassy yard stands left of center behind a metal fence, raising and lowering their arms repeatedly. The individual remains near a gray building with a tree nearby. The camera stays stationary throughout the scene.

A person is moving through the scene in the background.

Background elements (fence, buildings) are static; no significant environmental motion (e.g., wind) detected.


A person in a purple shirt and colorful leggings stands in a gym holding dumbbells at their sides. They lift the dumbbells upward to shoulder height, then lower them back down. Gym equipment is visible in the background, but the camera remains stationary throughout, capturing the exercise from a fixed front perspective.

A person performing a barbell overhead press: the individual lifts the barbell from waist height to overhead position and lowers it back down in controlled motion.

No shifting background or fluid/environmental motion (fire, water, wind). Static gym equipment (weights, chair, wall) remains fixed throughout the clip.


A hand holds a blue USB cable and inserts it into a blue port on a server, maneuvering the cable toward the port and guiding it into place; adjacent green and purple ports are visible on the server's front panel, with the camera maintaining a static close-up perspective.

A hand is manipulating a blue cable, inserting it into a port on an electronic device. The hand's motion is deliberate and discrete, driven by physical interaction with the cable and device.

The background consists of static electronic device components and wires with no fluid motion (fire, water, smoke) or uniform background shifting indicating camera movement.


RAW CAPTION: Got it, let's break this down. The video shows a yellow bulldozer. First, I need to note the main subject: the bulldozer. It's moving, so describe its motion. The bulldozer is yellow, large, with a metal blade. The operator is inside, but maybe not necessary unless specified. The background has a building and some vegetation, but keep background minimal. Chronological: the bulldozer starts, moves forward, blade pushing dirt. Camera perspective: the video seems to be a steady shot, maybe slight pan as it moves. Let's check the rules.

Focus on motion: the bulldozer moves forward across a muddy field. Appearance: yellow, large, with a wide blade. Spatial: moving from left to right? Wait, the video starts with the bulldozer in the frame, then it moves, so the camera might follow or stay fixed. Wait, the frames show the bulldozer moving, so the camera is likely static or slightly following. Let's check the example.

Rules: chronological order. So the bulldozer moves forward, blade pushing dirt, moving across the field. Background: a building and some bushes, but minimal. Camera: seems like a fixed camera, maybe a slight pan to follow the movement.

Let's draft: A yellow bulldozer with a large metal blade moves forward across a muddy field, pushing dirt ahead of it. The machine advances slowly, its operator visible inside the cabin. The camera maintains a steady perspective, slightly panning to follow the bulldozer's movement. Background includes a distant industrial building and sparse vegetation.

Wait, need to be concise. Let's check length. The example should be a paragraph. Let's see.

First, main subject: yellow bulldozer. Motion: moving forward across muddy field. Blade pushing dirt. Camera: steady, slight pan. Background minimal.

So: A yellow bulldozer with a wide metal blade advances slowly across a muddy field, pushing dirt ahead of it. The machine moves from left to right, its operator visible in the cabin. The camera remains stationary with a slight pan to follow the bulldozer’s progression, capturing minimal background elements including distant industrial structures and sparse vegetation.

Wait, but need to check if background is essential. Rule e says minimal unless essential. The background (building) is probably not essential for motion understanding, but maybe it's there. But rule e says "minimal", so maybe just mention if necessary. The bulldozer's motion is key, so focus on that.

Another version: A yellow bulldozer with a large metal blade moves forward across a muddy terrain, pushing dirt in front of it. The operator is visible inside the cabin as the machine advances steadily. The camera follows the bulldozer’s movement with a slight pan, maintaining a level perspective.

Wait, need to be chronological. The video starts with the bulldozer, then it moves. So "advances steadily" is the motion. Also, check the appearance: color (yellow), size (large), orientation (blade forward).

Let me make sure. The key points:

- Main subject: yellow bulldozer (large, metal blade)
- Motion: moves forward across muddy field, pushing dirt
- Operator visible in cabin
- Camera: slight pan to follow, steady perspective
- Background: minimal, industrial building and vegetation (but minimal, so maybe "distant industrial structures" or not mention? But if it's part of the scene, maybe include minimally.

Wait, the first frames show the bulldozer in a field with buildings in the background. So background elements are present but should be minimal. So maybe "background includes a low industrial building and scattered vegetation."

Putting it all together concisely.

"A yellow bulldozer with a large metal blade advances slowly across a muddy field, pushing dirt ahead of it. The operator remains visible inside the cabin as the machine moves forward. The camera maintains a steady perspective with a slight pan to track the bulldozer’s progression, capturing minimal background details including a distant industrial building and sparse vegetation."

Check for conciseness. Maybe trim "remains visible" to "operator visible".

"A yellow bulldozer with a large metal blade advances slowly across a muddy field, pushing dirt ahead of it. The operator is visible inside the cabin as the machine moves forward. The camera maintains a steady perspective with a slight pan to track the bulldozer’s progression, capturing minimal background details including a distant industrial building and sparse vegetation."

Yes, that seems to cover the rules: motion chronological, appearance, spatial (pushing dirt ahead), camera movement. Background minimal.

A single solid bulldozer is moving forward, pushing mud and spraying water from its blade. Motion is due to vehicle locomotion and physical interaction with ground material.

Background elements (building, trees) are stationary with no uniform shifting. Water spray from the bulldozer is a localized effect, not dominant fluid motion (fire, water flow, smoke, or wind), so ambient environmental motion is not dominant.


RAW CAPTION: Got it, let's tackle this video caption. First, identify the main subjects. There are two men. One is in a brown jacket with a head covering, using a large metal instrument, maybe a gong or something. The other is in a blue shirt and blue cap, working with a tool on the ground. They're sitting on the street, near a metal fence.

Chronological order: The first frame shows them sitting. Then, in the next frames, the man in blue is using a tool on a metal object (probably shaping it), while the other man is holding a rod or something on the metal piece. The camera moves a bit, maybe panning left or right? Wait, in the video, the camera might have a slight shake. Also, a person in red walks past. Background is a metal fence with some statues. But need to keep background minimal.

Focus on motions: The man in blue is actively working, maybe hammering or shaping. The other man is holding the metal piece steady. They're seated on the ground, close to each other. Spatial: man in blue is to the right of the man in brown? Wait, the first frame shows brown jacket on left, blue shirt on right. Then, as the video goes, the blue shirt guy is working on the metal, maybe moving the tool. The camera has a slight movement, maybe a pan.

Check rules: chronological paragraph. Start with their positions, then actions. Mention appearance briefly: two men, one brown jacket, head covering, one blue shirt, blue cap. Their actions: first, sitting, then the blue shirt man uses a tool (like a hammer) on a metal object, while the brown jacket man holds it. The camera perspective: maybe handheld, slight shake.

Background: metal fence with decorative elements, but minimal. Exclude text, names. So the caption should be:

Two men sit on a wet street near a metal fence; one in a brown jacket and head covering holds a large metal sheet while the other in a blue shirt and cap uses a tool to shape a metal object on the ground. A person in red passes by. The camera captures their movements with a slight shake.

Wait, check chronological: the sequence of actions. Initially, they are positioned, then the blue shirt guy works on the metal. Maybe the order: first, both are seated, then the blue shirt man starts working with the tool, the brown jacket man holds the metal. Then the person in red walks by. The camera movement: the video has a slight shake, maybe a small pan.

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

Two men sit on a wet street; one in a brown jacket and head covering holds a metal sheet, while the other in a blue shirt and cap uses a tool to shape metal on the ground. The blue-shirted man moves the tool rhythmically as the other steadies the sheet. A person in red briefly walks past. The camera maintains a close perspective with slight movement.

Wait, need to check if "rhythmically" is needed. The video shows them working, so maybe just "uses a tool to shape metal". Also, "metal sheet" or "metal object". The first part: in the frames, the brown jacket man is holding a large metal disc (like a gong), and the blue shirt man is working on it. Wait, the description in the frames: the brown jacket man is holding a metal disc with a rod, and the blue shirt man is using a tool (maybe a hammer) on a metal piece on the ground. Wait, looking at the frames: the first frame shows them with a metal disc. Then the blue shirt guy is working on a metal object (maybe the disc). Wait, maybe the blue shirt guy is hammering the metal sheet while the other holds it.

Wait, the video shows:

[0.0] Both sitting, brown jacket man holds a large metal disc with a rod, blue shirt man holds a tool (like a hammer) on a wooden board.

[1.0] Brown jacket man moves the rod, blue shirt man continues working.

[2.0] Same.

[3.0] Person in red walks past.

[4.0] Same positions.

So chronological: two men sit on the street; one (brown jacket, head covering) holds a large metal disc with a rod, the other (blue shirt, cap) uses a tool to shape metal on the ground. A person in red walks by. The camera captures them from a slightly elevated angle with minor shake.

But need to check if "on the ground" is accurate. The blue shirt man is sitting on a mat, working on a metal object on the street (the ground). The brown jacket man is on the ground too, holding the metal disc.

So the caption: Two men sit on a wet street; one in a brown

Two individuals (discrete solid objects) move their hands and limbs while working with materials on the ground, showing intentional physical actions.

The metal fence and ground show no uniform shifting; no fire, water, or smoke present. Background elements remain static.


A person in a black sleeveless shirt and dark shorts runs on a treadmill, slightly adjusting their posture as they move forward; another individual in a white shirt and dark shorts runs on an adjacent treadmill, positioned to the right of the main subject. The camera follows the primary runner closely, maintaining a handheld perspective with a slight shake throughout the sequence, capturing their rhythmic motion against the backdrop of gym equipment.

Runner on treadmill and other gym-goers are moving due to locomotion (running, walking).

Background (gym walls, equipment) is stationary with no uniform shift; no fluid/environmental motion (fire, water, wind) observed.


A person with dark hair and visible eye makeup holds a small object near their ear in a dimly lit environment, then moves both hands toward their face to adjust the object. They look to the side while holding it, followed by raising the object toward the camera. The camera maintains a close-up perspective with slight movement throughout the sequence.

A person (discrete solid object) moves their head and hands: adjusting glasses, then holding/interacting with a phone. Hand and head movements are voluntary locomotion.

Background is dark and static; no shifting walls or ground observed. No fluid motion (fire, water, smoke, wind) present.


A man in a dark suit presents a purple circular award to a man in a white robe with a sash, then moves left to hand the award to a man in a beige suit and red turban, who accepts it while the man in white steps back; the camera remains static.

The background elements (text and colored backdrop) are static with no shifting or fluid motion (no fire, water, smoke, or wind).


A person with long dark hair and a dark shirt with a circular emblem sits in a room featuring a couch, bed, and scattered furniture. They raise their right hand to display a small object, hold it momentarily, then lower it. The camera remains stationary throughout.

The person's hand and the lighter are moving as the person lights the object; body motion is minimal but present.

Background elements (couch, bed, walls) are static with no shifting. A brief flame emission occurs during the action, but it is not dominant motion.


A hand with a ring holds a black circular object against a white wall, then a yellow and black power drill drills into the object. The hand subsequently lifts the object away from the wall, revealing a drilled hole. The camera remains static throughout.

A hand holding a power drill manipulates a black object (likely a lens) and removes it from the wall, demonstrating clear discrete object motion.

The background (white wall) is static and shows no shifting or environmental fluid motion (fire, water, smoke, wind).


RAW CAPTION: Got it, let's break this down. First, the video shows a young child sitting on the floor. The child is wearing a white shirt with dark sleeves and black pants. They're handling money, picking up bills and putting them into a box. Let's track the actions step by step.

Start: Child is seated, looking at money on the floor. Then, they pick up a bill from the floor, hold it, and place it into a box. Next, they move the box towards themselves, maybe adjusting it. Then, they reach for another bill on the floor. The background is a light-colored carpet, so maybe that's the main setting.

Check the rules: focus on motion and behavior chronologically. Describe appearance briefly. Spatial relationships: the money is on the floor, child is sitting, box is in front. Camera perspective: it seems to be a static shot, maybe slightly shaky but no major movement. Background minimal, so just mention the carpet.

Now, structure the caption. Start with the child's action, then the sequence. Don't mention text on the shirt (since rule f says exclude text recognition). So the shirt has a design but we don't describe the text.

First sentence: Child sits on carpet, picks up dollar bill from floor. Then, holds bill and places into box. Next, moves box towards themselves, then reaches for another bill. The box is light-colored, the child's shirt is white with dark sleeves.

Check chronological order: 0-0.3s: child sitting, looking at money. 0.3-1.2s: picks up bill, holds. 1.2-2.5s: moves box, places bill. 2.5-3.6s: picks up another bill, adjusts. 3.6-4.7s: moves towards box, holds bill.

Wait, the video frames: first frame, child has a bill in hand, box open. Then picks up a bill, moves box, places bill, etc.

So the main actions: child sits, picks up bills from floor, places into box, moves box, continues handling money.

Appearance: child is small, white shirt with dark sleeves, black pants. Box is light-colored. Money is green bills on the floor.

Spatial: child sitting on carpet, money scattered around, box in front.

Camera: top-down, slight shake.

Now, make the caption concise.

" A young child in a white shirt with dark sleeves and black pants sits on a light-colored carpet, picking up green dollar bills from the floor and placing them into a light-colored box held in their lap. The child shifts the box and continues handling the bills, moving slightly as they interact with the money. The camera captures the scene from a top-down perspective with a slight shake, focusing on the child’s actions against a minimal background of the carpet."

Wait, check the rules: exclude text recognition (so no "502" on shirt). So "white shirt with dark sleeves" is fine, no text.

Also, chronological: first picks up a bill, then places into box, then moves box, then picks up another bill.

Make it flow as a paragraph.

"A small child wearing a white shirt with dark sleeves and black pants sits on a light-colored carpet, reaching to pick up green dollar bills scattered on the floor. The child lifts a bill, holds it, and places it into a light-colored box in their lap, then shifts the box to the side while continuing to gather bills from the floor. The camera maintains a top-down view with a slight shake, capturing the child's repetitive motion of collecting money."

Check for all rules:

a) Motion and behavior chronological: yes, picking up, placing, shifting box.

b) Appearance: child's shirt, pants; box, money.

c) Spatial: money on floor, box in lap.

d) Camera: top-down, slight shake.

e) Background minimal: carpet mentioned, which is the main background.

f) No text, no names.

g) Internal, but output as caption.

Let's make it more concise. Maybe:

"A young child in a white shirt with dark sleeves and black pants sits on a light carpet, picking up green dollar bills from the floor and placing them into a light-colored box. The child moves the box and continues gathering bills, shifting position while handling the money. The camera captures this top-down with a slight shake."

Wait, maybe "light-colored carpet" instead of "light carpet" for clarity.

Final check:

- Chronological: child picks up bill, places in box, moves box, picks up more.

- Appearance: child's clothing, box color, money color.

- Spatial: bills on floor, box in lap.

- Camera: top-down, slight shake.

Yes.

" A young child wearing a white shirt with dark sleeves and black pants sits on a
