A toddler in a red shirt and white pants crawls on a tiled floor toward an adult’s hand holding a small white ball. The adult, wearing blue jeans and sandals, moves their hand slightly, prompting the toddler to stand up and reach for the ball. The camera maintains a top-down view with minimal movement as the interaction unfolds.

The baby (solid object) exhibits clear locomotion: crawling, transitioning to a standing position, and moving toward the camera. Adult legs are present but stationary, indicating no dominant motion from other solid objects.

Background consists of static floor tiles with no visible fluid motion (water, fire, smoke) or significant environmental disturbances. Background elements remain largely stationary across frames.


A man in a red shirt and beige pants waters lush green plants in a garden. He holds a hose, directing water onto the foliage, then the camera zooms in to show the nozzle spraying water onto the leaves. The scene focuses on the watering action, with the man positioned beside the plants and the camera shifting from a medium view to a close-up of the water spray.

A person (wearing red shirt and beige pants) is holding and adjusting a hose to direct water towards plants.

Background elements (trees, foliage) are static; water flow from the hose is a secondary effect of the person's action, not dominant environmental motion.


A hand holds a metallic bolt with a hexagonal nut, rotating it to display its reflective surface and structural details. The hand then shifts the bolt away, revealing three wrenches aligned horizontally on a wooden surface in the background. The camera remains in a close-up perspective with subtle movement throughout.

Hands are manipulating a metallic mechanical object (e.g., socket or tool component), with discrete movement involving physical handling and rotation.

The background features static tools (wrenches) on a surface with no shifting or fluid motion. No fire, water, or wind is present.


Two individuals, one in a blue striped shirt with a white apron and the other in a red shirt with a white apron, stand side by side in a kitchen. The person in blue manipulates a white curd-like substance by stretching and twisting it with their hands, while the person in red uses a tool to cut or shape similar material. Both are positioned in front of a large blue basin filled with white liquid, with stainless steel pots visible in the background. The camera remains stationary, capturing a medium shot of the scene without noticeable movement.

Two individuals (wearing aprons) exhibit discrete hand/arm movements: stirring a blue pot and handling ingredients in a bowl.

Background elements (kitchen containers, walls) show no uniform shifting; no dominant fluid/environmental motion (fire, water, smoke) observed.


A pair of hands with gold-painted fingernails manipulates a red and orange crochet hook and green yarn, inserting the hook into a loop of yarn, pulling the yarn through to form a stitch. The left hand holds the yarn while the right hand operates the hook, with a white doily visible in the background. The camera maintains a close-up, steady shot focusing on the hands and the stitching process.

Hands manipulating yarn and a red tool (likely a crochet hook) exhibit controlled motion for creating a knitted or crocheted object.

The background features a static lace-like pattern with no shifting or fluid motion. No fire, water, smoke, or wind is present.

The background (dark surface and "Art & Design" text) is static with no shifting or environmental motion (fire, water, smoke, wind).


A person with long brown hair and a white t-shirt holds a black curling iron, raising it toward their head, then positioning the iron along their hair to curl a section. The subject remains centered against a light blue background, with the camera maintaining a static front view.

The woman is moving her head and arms to style her hair using a curling iron. The curling iron and hair are solid objects with motion due to explicit physical forces (her actions).

The background is a static blue wall with no shifting or environmental motion (fire, water, smoke, wind).


A person in a dark hoodie, dark pants, and white sneakers dances energetically in front of a white brick wall with a blue door to the left. They move their arms and legs rhythmically, stepping side to side and gesturing. The camera remains stationary throughout the sequence.

A single person (solid, distinct object) is performing dance movements: stepping, arm swings, and body rotations. Motion is driven by intentional locomotion and muscular action.

Background elements (wall, blue structure, bucket) show no shifting or fluid motion. No fire, water, smoke, or wind detected in the scene.


A shirtless man in red shorts lies on a blue-and-white striped lounge chair near a pool, with a white table holding a cup and glass beside him. A person in pink bikini bottoms walks past him from right to left, then exits the frame. The man shifts his arms and body, sitting up slightly while remaining on the lounge chair. Other people relax on nearby lounge chairs in the background. The camera remains stationary with minor adjustments to follow the walking figure.

The man in red shorts adjusts his position on the lounge chair (arm/leg movements), the woman in pink bikini interacts with his feet (arm movements), and background individuals show minor locomotion.

Background elements (pool, lounge chairs, distant people) are static with no uniform shifting. No fluid or environmental motion (fire, water, wind) dominates the scene.


Three performers in blue traditional outfits execute a coordinated stage routine: one stands balanced atop another’s shoulders, both holding poles with spinning discs, while a third performer to the right manipulates similar poles. Initially, the top performer maintains a wide stance with arms raised; as the sequence progresses, they shift weight, adjusting leg positions and arm movements to stay balanced. The bottom performer holds steady, and the right performer continuously rotates their discs. The camera remains fixed in a frontal position, capturing the motion with minimal movement.

Acrobats are performing a stack: one acrobat stands on the shoulders of another, and the top acrobat moves their arms and body to balance. Other performers in the background are also moving.

The background (stage, dark area, red light) remains stationary. No fluid or environmental motion (fire, water, smoke) is dominant. The scene is controlled by the performers' actions.


A person in a red hoodie over a striped shirt and long dark hair stands with their back to a refrigerator, then turns to face the camera, adjusting their hoodie while revealing their face. The scene occurs in a kitchen with a fridge adorned with notes and water bottles on the counter; the camera remains static with minimal shake.

A person wearing a red hoodie is moving: initially facing away, then turning to face the camera, adjusting their hoodie and making gestures. The motion is deliberate and localized to the person's body.

Background elements (refrigerator, water bottles, curtains) are static with no uniform shifting. No fire, water flow, smoke, or wind motion observed.


The video opens with two women operating sewing machines; one wears a checkered shirt with a red undershirt, the other a gray top with blonde hair. They work at the machines with spools of thread visible. The scene cuts to four women gathered around a table, one in a striped shirt with a pink bag, another in a dark top, a third in gray, and the fourth in green, interacting with materials. It then shifts to a close-up of hands with red nail polish sewing fabric. The camera remains static in the first and second scenes, then transitions to a close-up perspective.

Discrete objects moving: people (two women in the first scene, a group of people in the wider shot, and hands in the close-up). Their motion is due to explicit physical actions (sewing, talking, gesturing).

The background (indoor room with sewing machines, pictures on walls) is static in each frame. No fire, water, smoke, or wind is visible. The scene consists of multiple static shots (cutting between scenes), so no uniform background shift.


A man in a blue striped shirt and light blue pants walks left to right across a grassy field, approaching three black cows moving in unison. The cows, large and black, remain in a tight group as the man walks alongside them initially, positioned to their left. A small black dog runs alongside the herd, darting in front and behind the cows. The group continues moving forward across the field, with the camera panning slightly right to track their motion.

Discrete objects: a person in blue clothing and two cows (with a calf) are walking across the grassy field. Their motion is due to locomotion.

The background (trees and fence) is static and shows no signs of environmental motion (e.g., wind, water). No fire, smoke, or fluid motion is present.


A man in a striped shirt and dark shorts holds a long-handled gardening tool, moving it toward a tall, spiny cylindrical cactus positioned against a wooden wall. He steps slightly forward and adjusts the tool’s position near the cactus, then withdraws it while remaining adjacent to the plant. To the cactus’s right, a palm-like plant with long green leaves stands against the same wooden wall. The camera remains stationary, capturing the scene from a fixed angle with minimal background detail.

The man is moving while using a tool to trim the cactus, demonstrating discrete physical motion.

A pair of light-skinned hands with neatly trimmed nails manipulates a metallic needle and light purple-and-white yarn. The right hand holds the needle while the left hand threads the yarn through the needle's eye, then pulls the yarn to form a loop. The hands move in tandem to create the stitch, with the needle positioned horizontally. The background remains blurred, emphasizing the hands and needle. The camera maintains a close-up, static view focused on the hands' precise movements.

Hands are actively manipulating yarn and knitting needles, demonstrating discrete physical actions (looping, pulling yarn). The yarn and needles move as solid objects due to human interaction.

The background appears blurred but shows no significant shifting or fluid motion (fire, water, wind). Background elements (e.g., indistinct fabric) remain static relative to the scene.


In a gym setting, a woman wearing a white tank top and blue shorts bends over a barbell resting on wooden blocks, lifting it vertically to overhead position while standing. A man in a yellow shirt stands to her left, observing. Another individual in dark clothing exits the frame from the right. The background features walls with posters and gym equipment. The camera remains stationary throughout.

The main subject (person in blue shorts and black shirt) lifts a barbell from a bent position to an upright standing position, demonstrating physical exertion. Other individuals in the background are stationary or minimally moving but not the primary focus.

The background (walls, posters, floor) is stationary; no fire, water, smoke, or wind is present.


Two individuals, one with red hair in dark clothing and another in all black, move dynamically in an indoor space. The red-haired person bends toward the floor, interacting with objects, while the black-clad individual shifts position near a desk. The camera moves erratically, capturing their motion with slight shake. Background includes a desk and scattered items, but focus remains on their actions.

Two people are moving: one with a stick interacting with objects on the floor, the other moving around the room. The stick is being swung and hit against objects. The people's movements are due to their own locomotion and actions.

No shifting background; no fire, water, smoke, or wind. Background elements (walls, floor, amplifier, guitar stand) are static.


Hands pour a brown powder from a metal container into a sieve. A person in a white polo shirt stands at a table, holding and shaking a tall stack of sieves. The camera transitions from a close-up of the pouring action to a medium shot of the person shaking the sieves.

Discrete objects include hands pouring granular material through a sieve and a person manipulating a large cylindrical object in an office setting. The motion originates from human interaction with solid objects.

No significant ambient motion (no fire, water, smoke, wind) or shifting background elements observed. Background includes static office furniture and walls in the second scene.


A bartender in a white shirt stands behind a bar, bends forward to adjust an object on the counter, then returns to an upright stance while maintaining position behind the bar. The camera remains static throughout, focusing on the bartender's movements.

The bartender (solid, discrete object) exhibits locomotion and hand movements (mixing drinks) driven by physical actions.

Background elements (bar counters, bottles, screens) show no uniform shifting. No fire, water, smoke, or wind motion observed.


RAW CAPTION: Got it, let's break this down. First, the video starts with a large crowd seated in a stadium-like area, trees in the background. Then it transitions to a top-down view of a track or field with many small figures (probably runners) lined up in rows. The crowd is dense, black-and-white, so no color. The main subjects are the crowd and the runners. Chronologically: first the crowd, then the runners on the track. Need to mention the motion—crowd is stationary, then the runners might be starting or moving. Wait, the video clips: first frame is crowd, then the next is the track with runners. So the sequence is crowd view, then top-down of the track with many people in rows. The runners are small, numerous, arranged in lines. Background is trees in first scene, then the track surface. Camera movement: from a wide shot of the crowd (side view) to a top-down view of the track. Need to keep background minimal. Let's structure it: The video opens with a large crowd seated in a stadium area, densely packed and facing a central track, surrounded by tall trees. It then transitions to a top-down view of the track, where numerous small figures—likely athletes—are arranged in multiple parallel lines across the ground. The camera shifts from a side perspective of the spectators to a direct overhead angle capturing the organized rows of participants. The background in the first scene includes trees, while the second scene focuses on the track surface with the participants. Wait, but the rules say minimal background unless essential. So maybe: The video begins with a dense crowd of spectators seated in tiered rows within a stadium, surrounded by tall trees. The camera then pans down to a top-down view of a track where numerous small figures, likely athletes, are positioned in neat parallel lines across the ground. This sequence shows the crowd first, then the athletes in formation. Need to mention motion: the crowd is static, then the athletes might be starting (but the clips don't show movement, just the lines). So "arranged in neat parallel lines" implies they're in formation. The camera movement: from a side view of the crowd to top-down on the track. So the final caption would be: A large crowd of spectators fills tiered seating in a stadium, surrounded by tall trees; the camera then shifts to a top-down view of a track with numerous small figures arranged in parallel lines. The crowd is stationary, while the track scene shows organized rows of participants. But need to check the rules: "Focus primarily on motion and behavior of main subjects". The main subjects are the crowd and the athletes. The crowd is stationary, the athletes are in formation. Also, "briefly describe appearance and number" — crowd is dense, many people; athletes are small, numerous. Spatial relationships: crowd is in the stands, athletes on the track. Camera: starts with side view, then top-down. Let's make it concise. "The video opens with a dense crowd of spectators seated in tiered rows at a stadium, surrounded by trees, then transitions to a top-down view of a track where numerous small figures are arranged in parallel lines. The crowd remains stationary, while the track scene shows organized rows of participants." Wait, but "motion and behavior"—the crowd is static, the athletes might be in a starting position (so behavior is being positioned). But the clips are static, so maybe "arranged" is the behavior. Let's check the examples. The first frame is crowd, then the next is the track. So the sequence is crowd, then track. The camera moves from the side of the stadium to top-down on the track. So the caption should be chronological: first the crowd, then the track view. So the caption: The video begins with a large crowd of spectators seated in tiered rows within a stadium, surrounded by tall trees; it then transitions to a top-down view of a track where numerous small figures, likely athletes, are positioned in neat parallel lines across the ground. The camera shifts from a side perspective of the spectators to an overhead angle capturing the organized rows of participants. But need to keep it concise. Let's trim: The video opens with a dense crowd of spectators in tiered stadium seating, surrounded by trees, then cuts to a top-down view of a track with numerous small figures arranged in parallel lines. The crowd is stationary, while the track scene shows organized rows of participants. But "behavior"—the crowd is sitting, the athletes are in lines. Also, number: "large crowd", "numerous small figures". Appearance: black-and-white, so "dense crowd", "small figures". Let's write the exact caption: <caption_output>The video starts with a large crowd of spectators seated in tiered rows at a stadium surrounded by trees, then shifts to a top-down view of a track where numerous small figures are arranged

A large group of people (discrete objects) moving in a coordinated pattern on a field.

The background elements (trees and field) are static in both scenes. No fluid or environmental motion (fire, water, smoke, wind) is observed.


A person with dark hair and a blue top applies an eyeliner pencil to their right eye, holding the tool steady and moving it along the eyelid in a deliberate motion. The background features a door and dimly lit surroundings. The camera maintains a close-up, static perspective focused on the person’s face throughout the sequence.

A person is moving their hand to apply makeup with a brush. The brush and hand are the discrete objects in motion, tracked as a bounded movement.

The background (door and red fabric) remains static with no shifting or fluid motion. No fire, water, smoke, or wind observed.


In a dimly lit indoor venue, a tall man in a dark blue suit walks steadily from left to right through a seated crowd, passing in front of a man in a gray suit who dances near a keyboard on the left. The camera follows the blue-suited man with a slight shake, capturing the crowd’s stillness and the venue’s warm lighting from wall sconces.

Two men (one in blue suit, one in gray suit) are dancing in the foreground, moving their arms and bodies. Additional people are seated in the background but mostly stationary.

The background walls and floor are mostly static. The candle flames in the background exhibit minor flickering (ambient environmental), but this is not dominant. The main scene is a dance floor with people dancing.


A person in a shiny silver costume with a helmet and large shoulder pads interacts with a person in a green shirt; the silver figure turns and walks through a crowd of people in an outdoor area with stairs and buildings in the background. The silver-costumed individual moves forward, shifting positions relative to the green-shirted person, while other pedestrians walk past in the background. The camera follows the silver figure’s movement with slight handheld shake, maintaining a medium shot perspective.

The main discrete objects are the person in the silver astronaut suit (with helmet) and the child in the green shirt. They exhibit locomotion (walking, turning) and interaction. Other pedestrians in the background also move.

The background (buildings, signs) remains static and unshifting, with no fire, water, smoke, or wind present. The only motion is from discrete objects (people).


A hand reaches from the top left toward a plastic bag containing green lettuce on a countertop with various food items including a colorful plate with meat, bread slices, and condiments. The hand lifts the lettuce from the bag. The camera maintains a top-down perspective with no movement.

A hand (discrete object) moves to pick up and place a bag of celery on a plate. The celery bag is also moved by the hand.

No shifting backgrounds or fluid/environmental motion (fire, water, wind) observed. Background elements (table, plate, packages) remain stationary.


A person wearing black clothing and blue gloves pours items from a container onto a circular object featuring a red and white symbol, which rests on a flat surface. The container is held above the object as the individual manipulates its contents. The camera maintains a close-up perspective, focusing on the hands and the object with minimal movement.

A person's hands manipulate a container with a red circular symbol, moving tools and materials in deliberate, controlled motions.

A child in a white shirt and dark pants runs across a gym floor, trips, and falls. An adult in a white shirt and dark pants approaches, bends down to lift the child, and the child holds the adult’s arm. The adult stands with the child in front. The camera remains handheld with slight shake throughout the sequence.

Two individuals: one person crawls on the floor and stands up, while the other person performs dynamic movements (e.g., arm gestures and body swaying).

The background walls and floor remain static throughout the video, with no uniform shifting or fluid motion observed. No environmental elements (fire, water, smoke) are present.


RAW CAPTION: Got it, let's tackle this. First, the video starts with a white screen with pink text: "DRE BALDWIN" and some email and MySpace info. Then it goes to a red text "WWW.DREALDAY.COM". Then it cuts to a basketball court. A person in black and white athletic wear (jersey and shorts) is dribbling a basketball. The text "100 x" appears on the floor. Now, the rules say to focus on motion and behavior chronologically. Exclude text recognition, but wait—rule g says don't include text recognition, but the task is to describe the video. Wait, rule f says exclude text recognition, named characters, or stylistic analysis. So for the text in the video, like the website, we might not mention it? Wait, but the video includes those text screens. Wait, the user says: "Exclude text recognition"—so we don't mention the text like "www.drealday.com". Wait, let's check the rules.

Rule f: "Exclude text recognition, named characters, or stylistic analysis." So the text in the video (like the website) should not be part of the caption. So the caption should focus on the motion of the basketball player, not the text that appears. So first part: white screen with text (but exclude text recognition), so we can say "A white screen with pink text fades out". Then next part: "A white screen with red text 'www.drealday.com' fades out". Then the basketball court scene.

Wait, but the rules say "Focus primarily on the motion and behavior of main subjects". So the initial screens are text, but we need to describe the video chronologically. Let's break down the frames:

Frame 0: White screen with pink text (DRE BALDWIN, email, myspace). But per rule f, exclude text recognition, so we can describe the screen as a white background with text (but not mention the text content). Then frame 1: similar, but text is different? Wait, the video starts with [0.0] showing "DRE BALDWIN" etc. Then [1.4] "WWW.DREALDAY.COM". So the first part is text screens, then the basketball.

But the caption must follow chronological order. So the sequence is:

1. White screen with pink text (excluding text recognition, so describe as a white screen with text, but not name the text).

Wait, but rule f says "Exclude text recognition, named characters, or stylistic analysis." So the text is part of the video, but we can't mention what the text says. So we need to describe the visual elements without the text content.

But the problem is that the initial frames have text, but the task is to describe the motion and behavior of main subjects. The main subject in the first frames is not a person, but the text. Wait, but the rules say "main subjects (people/animals/objects)". So in the first frames, there's no people/animals, just text. But the task says "Focus primarily on the motion and behavior of main subjects". So if there are no main subjects, describe the scene.

Wait, the video:

[0.0] White screen with pink text.

[1.4] White screen with red text.

[3.6] Transition to basketball court: a person in black and white athletic wear dribbling a basketball on a wooden court with red walls, text "100 x" appears on the floor.

So the chronological order:

1. A white screen with text fades into view (but not text content).

2. A white screen with red text fades into view.

3. The scene shifts to a basketball court where a person in black and white athletic wear is dribbling a basketball; the text "100 x" appears on the wooden floor.

But according to rule f: "Exclude text recognition". So even though "100 x" appears, we have to exclude text recognition. Wait, but rule f says "Exclude text recognition", which means not mention the text. So "100 x" should not be part of the caption.

Wait, let's read rule f again: "Exclude text recognition, named characters, or stylistic analysis."

So text recognition is when you say "the text '100 x' appears". So we can't mention the text. So the description of the basketball scene would be: a person in black and white athletic wear dribbling a basketball on a wooden court with red walls.

Also, the background: the red walls are part of the court, but minimal background description. So "wooden court with red walls" is minimal.

Now, the spatial relationships: the person is on the court, dribbling. The camera perspective: in the basketball scene, the camera is probably

A person (wearing black shorts and black shoes) is jumping vertically on a wooden gym floor. The motion is discrete and solid, driven by muscle force.

The background (red wall and wooden floor) is stationary with no shifting or fluid motion. There are no environmental fluids (fire, water, smoke, wind) present.


Two hands manipulate blue yarn and an orange crochet hook. The left hand holds the yarn while the right hand guides the hook through loops, pulling yarn through to form stitches. The hands move in coordinated motion, with the hook entering and exiting loops. The background is a dark surface. The camera remains in a close-up, static perspective throughout.

Two hands manipulate a blue yarn and an orange crochet hook, moving in controlled motions to form stitches through yarn loops. The hands and hook exhibit discrete, solid-object motion consistent with manual dexterity.

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


A person wearing a dark shirt sits in front of a keyboard, their hands moving rhythmically across the keys. The individual remains seated throughout, with their posture slightly angled toward the instrument. A window with horizontal blinds is visible behind them, allowing diffused light to filter into the space. The camera maintains a static position, capturing the scene from a fixed angle with no noticeable movement or shake.

Person's hands and upper body exhibit discrete motion while playing the keyboard. Hand movements press piano keys in a rhythmic pattern, indicating explicit physical locomotion (muscle-driven motion) of solid objects.

Background (window, blinds, room interior) is static; no environmental motion (fire, water, smoke, wind) observed. Outdoor view through window remains consistent with no fluid dynamics or wind effects.


A man in a white shirt and black shorts leans toward a seated girl in a blue top, reaching out to touch her face. He then pulls his hand back and steps away, while the girl looks up at him. The camera maintains a close angle, slightly shaking as it follows the man’s movements, with the boat’s interior and ocean visible in the background.

The officer (in white shirt) and the woman (sitting) are the discrete objects. The officer's hands move to interact with the woman's head, showing explicit physical actions (touching, adjusting) driven by human locomotion.

The background includes water and boat elements, which show minimal shifting (indicating the camera is likely fixed on the boat). No dominant fluid/environmental motion (fire, water, smoke, wind) dominates the scene.


A person with short dark hair holds a large yellow banana close to the camera, peeling it with both hands while moving the fruit in front of their face; the banana peel is partially removed and the fruit is rotated, with the camera remaining in a close-up perspective showing slight movement and a plain indoor background.

A person is peeling and eating a banana; the banana and the person's hand/mouth are moving in discrete, solid object motion.

The background (walls, ceiling) is static with no fluid or environmental motion (fire, water, smoke, wind) detected.


RAW CAPTION: Got it, let's tackle this. First, the video starts with two people in a room with a green chalkboard. The first person is in a checkered shirt and dark pants, moving towards the right. The second person, also in a checkered shirt but maybe different, is near the chalkboard. Wait, the first frame shows two people: one in checkered shirt (maybe black and white) and another in a different shirt. Then the scene shifts to a classroom setting with a green chalkboard, a wooden table with a stack of clothes or something. Then two people: one in white shirt and dark pants, and another in a dark shirt with a checkered pattern, maybe. They start moving, the one in white shirt spreads their legs wide, maybe doing a move, and the other is crouching or bending. The motion: the person in white shirt extends legs, then the other person is on the floor, then the white-shirted person moves their arms, maybe. Then the other person gets up. Wait, the sequence: in frame 0, two people in a room with green chalkboard. Frame 1, same, but the person on the right is in motion. Frame 2, the person in white shirt and dark pants is in a low position, maybe stretching, and the other person is bending. Then frame 3, the person in white shirt spreads legs further, and the other is on the floor. Frame 4, white-shirted person is still in that stance, other is on the floor. Frame 5, white-shirted person moves arms, other is getting up.

Need to describe chronologically. Main subjects: two people. First frame: two people (one in checkered shirt, one in white? Wait, the first frame shows a person in checkered shirt (maybe black and white) moving left, and another in a different shirt (maybe dark) on the right. Then the next frames shift to a classroom with green chalkboard, wooden table, etc. Wait, the second frame says "a room with a green chalkboard, a wooden table with a stack of clothes or blankets, and two people: one in a white shirt and dark pants, and another in a checkered shirt (gray and white?)".

So timeline:
- Start: Two people in a room with green chalkboard. One (checkered shirt, dark pants) walks left, another (dark shirt, maybe) is on the right.
- Then the scene transitions to a classroom view. Now, two people: one in white shirt/dark pants, the other in checkered shirt (gray/white), and they move. The white-shirted person spreads legs wide, bends, then the other person crouches on the floor. Then the white-shirted person remains in stance while the other is on floor. Then the white-shirted person moves arms, and the other gets up.

Wait, the actual video frames: [0] shows two people in a room with green chalkboard (the room has a green chalkboard, maybe a classroom). [1] same room, the person on the right is bending over, left person is walking left. Wait, maybe better to list each frame's action.

Frame 0: Two people, one in checkered shirt (black/white) moving left, another in dark shirt on the right. Background: green chalkboard, wooden table, etc.

Frame 1: The person in white shirt (left) spreads legs wide, bends, other person (right) is bending over.

Frame 2: White-shirted person remains in low stance, right person crouches down.

Frame 3: White-shirted person maintains stance, right person is on floor.

Frame 4: White-shirted person moves arms, right person is on floor.

Frame 5: White-shirted person moves, right person gets up.

So chronologically: Initially, two people in a classroom setting with a green chalkboard. The person in a white shirt and dark pants (appears in frame 1) extends legs wide and lowers their body, while the other person in a checkered shirt (gray and white) crouches and then moves onto the floor. The white-shirted individual maintains a wide-legged stance while the other person is on the ground. The white-shirted person then moves their arms, and the checkered-shirted person begins to rise. The camera remains static, capturing the scene from a slightly elevated angle, with minimal background details.

Wait, check the rules: minimal background descriptions. So mention only essential background. The main subjects are two people. Their appearance: white shirt/dark pants, checkered shirt (gray/white, maybe).

Let me check the frames again:

Frame 0: Two people. One is in checkered (black/white) shirt

A person (wearing gray shirt and dark pants) moves by bending down, standing up, and walking away. Another person is present but stationary in the first scene.

The background elements (green chalkboard, wooden table in first scene; green wall, bench in second scene) are static with no shifting or environmental fluid motion.


A person in blue clothing sprays a dark surface with a handheld tool, moving it in a sweeping motion. The person then lowers the tool and steps away, leaving the surface with visible spray marks. The camera maintains a top-down perspective with slight shifts to follow the motion and tool placement.

A person in blue clothing moves their arms and hands while manipulating a tool near a yellow object (possibly a container), exhibiting discrete physical actions.

Background elements (metal structures, wall) show no uniform shifting; no fire, water, or smoke present; ambient environmental motion is negligible.


RAW CAPTION: Got it, let's break down the video. First, the scene is a track and field event, probably discus or hammer throw. The main subject is an athlete in a red uniform with the number 24, standing in a throwing circle. Let's check the sequence.

At the start (0.0s), the athlete is crouched, preparing to throw. Then, they spin around (0.5s), which is typical for discus/hammer throw to build momentum. After spinning, they release the discus (around 1.5s), then step out of the circle. Then, they walk away, and another person in red (number 26) is nearby.

Wait, the video shows: the athlete in red (24) starts in a ready position, spins, releases the object (discus), then walks off. Other people: one in red 26, one in black 26, and another in red 4. The background has a field, cars, fence.

Need to describe chronologically. Start with the athlete's action: preparing, spinning, throwing, then moving away. Mention their appearance: red shirt with 24, white shorts maybe. The others are standing around, some in red, some black. Spatial: the thrower is in the circle, others around. Background minimal.

Camera perspective: seems like a stationary shot, maybe slight angle but not moving much. The video shows the action from behind the thrower, so camera is behind the thrower's initial position.

Let's structure:

A female athlete in a red uniform (number 24) stands in a throwing circle, crouched in preparation. She begins to spin clockwise, building momentum, then releases a discus, which flies through the air. After releasing, she steps out of the circle and walks away toward the field. Around her, several individuals in red and black uniforms (numbers 26, 4) stand nearby, observing. The background features an open grassy field with distant vehicles and a fence. The camera maintains a steady, behind-the-thrower perspective throughout.

Wait, check if the athlete is female? The problem says "people" so maybe not gender-specific. Let's avoid gender. "An athlete" not "female athlete".

Also, the video starts with the athlete in position, then spins, throws, then walks. Let's confirm the frames:

Frame 0.0: athlete in circle, crouched.

Frame 0.5: spinning.

Frame 1.5: throwing (discus in air).

Frame 2.5: stepping out, walking.

Others: red 26, black 26, red 4 are standing around.

So the caption should be:

An athlete in a red uniform with the number 24 stands in a circular throwing area, crouched and preparing to throw. She spins clockwise, then releases a discus, which arcs through the air before landing. After releasing, she steps out of the circle and walks away across the grassy field. Nearby, several other individuals in red and black uniforms (some with numbers 26, 4) observe. The background shows an open field with distant vehicles and a fence. The camera remains stationary, positioned behind the thrower, capturing the sequence from a fixed angle.

Check rules: chronological, motion, appearance (red uniform 24), spatial (thrower in circle, others around), background minimal. Camera perspective: stationary, behind thrower.

Wait, "red uniform with number 24" – the athlete is wearing red shirt, maybe red shorts.

Also, "in front of, to the left" etc. In the video, the thrower is in the center of the circle, others are around. So "several individuals in red and black uniforms stand nearby".

Need to keep concise. Let's try to shorten.

An athlete in a red uniform (number 24) is positioned in a throwing circle, crouched and preparing to throw. She spins clockwise, releases a discus, and steps out of the circle to walk away. Several individuals in red and black uniforms (including those with numbers 26 and 4) observe from around the circle. The background includes an open grassy field with distant vehicles and a fence. The camera remains stationary, capturing the action from behind the thrower.

A volleyball is moving through the air due to a spike; players are jumping and moving to play the ball.

The background (building, tree, ground) is static; no ambient environmental motion (fire, water, wind) is visible.


RAW CAPTION: Got it, let's tackle this. First, the video is a street scene at 42nd Street, 2014. The main subject is tap dancing. Let's see the frames. In the first frame, there's a crowd, then a person starts dancing. The dancer is in the middle, maybe wearing casual clothes. Let's break it down chronologically.

Start with the initial scene: people gathered, some sitting, some standing. Then a man (or person) stands up and begins tap dancing. The dancer moves rhythmically, tapping their feet. The crowd watches. Then maybe the dancer continues moving around, interacting with the space. The camera seems to stay fixed, maybe slightly shifting to follow the dancer.

Wait, the rules say focus on motion and behavior of main subjects. Main subject is the tap dancer. Let's check the appearance: the dancer is a man, probably, wearing casual clothes—maybe dark shirt, pants. The action is tapping feet, moving in place or around. Number: one main dancer, others are onlookers.

Chronological order: The video starts with a crowd in an urban setting (subway station maybe). A person stands up from a seated position and begins tap dancing. The dancer performs with rhythmic foot movements, occasionally shifting position within the crowd's attention. Onlookers stand or sit, watching. The camera remains stationary, capturing the dancer's movements against the bustling background.

Background minimal: urban, crowd, maybe subway platform. But per rule e, minimal unless essential. So focus on the dancer's actions.

Let's structure:

- Initial scene: crowd gathered, some seated, some standing.
- Then, a person (main subject) stands up and starts tap dancing.
- Dancer performs with foot taps, moves rhythmically, maybe steps around.
- Onlookers observe.
- Camera: stationary, likely fixed angle, no major movement.

Make it concise paragraph. Check for all rules.

Avoid text recognition: the text "tap dancing 42nd street, 2014..." is not to be included. So describe the action without mentioning the text.

Appearance: dancer is male, casual attire (like dark shirt, light pants?), but maybe not specific. Rule b says "briefly describe appearance and number". So "a man in casual clothing" or "a person".

Spatial relationships: dancer is in the center, onlookers around.

Camera: the video seems to have a fixed perspective, possibly handheld but slight shake? Wait, the frames don't show camera movement, but the instruction says "camera perspective and movement". Let's see the clips: the first frame shows a crowd, then the dancer is in the middle. Camera might be static, capturing the scene.

Putting it all together:

In a bustling urban setting, a crowd gathers with some seated and others standing. A man in casual attire stands up and begins tap dancing, rhythmically tapping his feet as he moves slightly within the group. Onlookers remain stationary, observing the performance. The camera maintains a steady, fixed perspective throughout the sequence.

Wait, check if "bustling urban setting" is too vague. Maybe specify subway station, but rule e says minimal background unless essential. The scene is a subway platform (from the background signs and layout). But maybe it's safe to say "urban area" or "public space".

Let me recheck the frames. The first frame shows a subway platform: there's a sign with "42nd street", and people are on a platform. So it's a subway station. But the rules say minimal background, so maybe not necessary to mention subway, but the motion is in public space.

Alternatively: In a busy public space, a crowd includes seated individuals and standing onlookers. A person in casual clothing stands and performs tap dancing, using rhythmic foot movements. The dancer shifts position slightly while the audience watches. The camera remains stationary, capturing the scene from a fixed angle.

Yes, that's concise. Now, check rules:

a) Motion chronological: starts with crowd, then dancer stands and dances.

b) Appearance: person in casual clothing (number 1 main, others onlookers).

c) Spatial: dancer in center, onlookers around.

d) Camera: stationary.

e) Background minimal.

f) No text.

g) Don't include reasoning.

So final caption:

A man in casual clothing stands and begins tap dancing in a busy public space, rhythmically tapping his feet while slightly shifting his position. Onlookers, some seated and others standing, observe the performance. The camera remains stationary, capturing the scene from a fixed perspective.

Briefly describe what discrete, solid objects are moving.

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


A pair of older hands with visible veins holds a black smartphone, while the right hand sequentially presses numbered keys on the screen's keypad. The left hand stabilizes the device, with the green background remaining static. The camera maintains a top-down close-up view without movement throughout the sequence.

Discrete solid objects (human hands) are interacting with a smartphone, pressing buttons and performing explicit physical movements.

The background is a solid green surface with no shifting or fluid motion (no fire, water, smoke, or wind visible). Static background elements remain consistent.


RAW CAPTION: Got it, let's break down the video. First, the scene is an open field with trees in the background. There are a few people and a horse. Let's look at the sequence.

At the start, there's a person on a horse (maybe brown horse) moving from right to left. Then, two people running towards the horse. Wait, in the first frame, there are two people on the left? Wait, no. Let's check the timestamps.

Frame 0: Maybe a person running left, horse on the right. Then frame 1: same? Frame 2: people moving, horse. Frame 3: the two people are now running towards the horse? Wait, the video shows a horse with a rider moving from right to left. Then two people (maybe wearing light-colored shirts) are running across the field towards the horse. Wait, the description should be chronological.

Wait, the video starts with a field, then the horse and rider are moving. Then two people run towards the horse. Let's see:

In the video, the main subjects: a horse (brown, ridden by a person) moving from right to left. Then two people (light-colored clothing, maybe shirts) are running from the left towards the horse. Wait, in the frames, the horse is moving, and the two people are moving towards it. So the sequence: horse is moving left, two people run towards it. Wait, in frame 2, the horse is more visible, and the two people are running towards it. Then in frame 3, the horse is still moving left, and the two people are near it. Then frame 4, the horse is further left, and the two people are behind it.

Wait, let's parse the frames:

Frame 0: Maybe a bit blurry, but the horse is on the right. People are on the left, maybe running.

Frame 1: The horse is moving left, riders? Wait, the description says "a horse with rider" moving from right to left. Then two people (two individuals, light-colored shirts) run from the left towards the horse.

Frame 2: The horse is still moving left, and the two people are closer to it.

Frame 3: The horse is further left, and the two people are now behind it, continuing to run?

Wait, maybe the two people are running towards the horse. So chronological order: the horse (brown, ridden by a person) moves from right to left across the field. Simultaneously, two individuals wearing light-colored shirts run from the left side of the frame towards the horse. As the video progresses, the horse continues moving left, and the two runners approach it until the horse is further left and the runners are behind it. The background is a field with trees, minimal description. Camera seems to be static, maybe slight movement? Wait, the problem says to describe camera perspective and movement. The caption must mention that. Let's check the rules: "Conclude with the camera perspective and movement (e.g., top-down, pan left, slight shake)."

Looking at the video, the camera seems to be handheld, maybe slightly shaky. The background is a field with trees, but minimal. So the main motion: horse and rider move left, two people run left to right (towards the horse). Wait, no: the horse is moving from right to left, so the rider is moving left. The two people are running from left to right (since in frame 0, they are on the left, and in frame 4, they are more to the right). Wait, maybe the two people are running towards the horse, which is moving left.

Wait, let's reorient. Let's list the elements:

- Horses: one brown horse with a rider, moving from right to left.

- People: two individuals, wearing light-colored shirts (maybe beige or white), running from the left side of the frame towards the horse.

Chronological order:

1. The horse and rider are visible on the right side of the field, moving left.

2. Two people (light clothing) enter the frame from the left and begin running towards the horse.

3. As the video progresses, the horse continues moving left, and the two people run closer to the horse.

4. By the end, the horse is further left, and the two people are near the horse's position.

Wait, but in the frames provided, frame 0: maybe the horse is on the right, two people on the left. Frame 1: horse moving left, people still left. Frame 2: people moving right (towards horse). Frame 3: people closer to horse. Frame 4: horse is left, people are behind.

Wait, the key is the motion: the horse is moving left, the two runners are moving towards the horse (so their

Two people and a horse; the horse is galloping and one person is running, both moving due to locomotion.

Background (trees and sky) is static with minimal environmental motion (light wind causing slight tree sway); not dominant.


A pair of hands with red nail polish manipulates a transparent plastic bag containing a green rectangular object, then lifts the bag to display the object. Subsequently, the hands open a box filled with colorful containers holding green items and rearrange the containers within the box. The camera begins in a close-up of the hands and bag, then shifts to capture the box's contents and the hands' movements.

Hands with red nail polish move the green tray, adjust its position, and interact with small round objects on the tablecloth (e.g., pressing, positioning).

Background elements (green tray, colorful tablecloth with cupcake patterns, surrounding objects) show no uniform shifting or fluid motion; no fire, water, or smoke visible.


A lifter in dark athletic clothing lifts a barbell with yellow weight plates from the ground to shoulder height, then overhead, before lowering it. The lifter moves centrally in the gym, with a mirror reflecting their actions to the left and other individuals observing from the background. The camera remains static, capturing the action from a fixed side perspective.

The weightlifter (person) moves the barbell (with weights) through a lifting motion: picking it up from the ground, raising it to the shoulders, then overhead, and finally dropping it. Other individuals in the background are stationary or minimally moving.

Check for shifting backgrounds or fluid/environmental motion: The background (walls, door, gym equipment) is static and shows no shifting or fluid motion. There are no flames, water, smoke, or wind effects visible in the gym environment.


A woman with long brown hair and a black-and-white patterned top plays a grand piano, her hands moving rhythmically over the keys. The camera slowly zooms in from the side, focusing on her hands and the piano, with minimal background detail. The angle shifts slightly closer to the keyboard as she continues playing.

The woman's hands are actively moving across the piano keys, demonstrating discrete solid-object motion due to explicit physical interaction (playing the piano).

The background features a wall with glass decorations and a lamp; no uniform shifting of static elements (walls, fixtures) is observed, and no fluid/environmental motion (fire, water, smoke, wind) is present.


RAW CAPTION: Got it, let's break this down. The video is a black-and-white shot of a person playing a flute. First, I need to describe the main subject: a person in a dark shirt playing a flute. The chronological order would be the person holding the flute, their hands moving over the keys, and the slight movement of their head. Appearance: dark shirt, flute with keys. Spatially, the person is centered, maybe with some background elements but minimal. Camera: the shot seems to be a close-up, maybe slight camera movement? Wait, the frames show the person's profile, hands moving. Let's check the rules. Rule a: motion and behavior chronologically. So the person is playing, hands moving over the flute keys, head turning slightly. Rule b: appearance—dark shirt, flute (silver keys maybe, but since it's B&W, just flute). Number: one person. Rule c: spatial—no specific relations, just the person in the frame. Rule d: camera perspective—close-up, maybe slight pan or movement? The video frames show a close-up of the person from the side, maybe the camera is static but the person moves. Wait, the video's first frame is the person playing, then slight movement of the head and hands. So camera perspective is close-up, maybe slight movement. Rule e: background minimal, so maybe just mention it's dark background. Let's draft: A person in a dark shirt plays a flute, hands moving over the keys while head turns slightly. The flute has visible keys. Background is dark and indistinct. Camera captures a close-up profile of the person, with minimal movement. Wait, need to be concise. Let's structure:

In a black-and-white sequence, a person wearing a dark shirt holds a flute, their fingers moving over the instrument's keys as they play. The person’s head turns slightly to the side, maintaining focus on the flute. The background is indistinct and dark. The camera maintains a close-up profile view with minimal movement.

Wait, check rules. Rules say "conclude with camera perspective and movement". So need to end with that. Let's check the example output. Hmm. Let's make sure. The caption should be chronological: person starts playing, hands move, head turns, etc. Appearance: dark shirt, one person. Spatial: no other objects, so just the person. Background: minimal, dark. Camera: close-up, maybe slight pan? Looking at the frames, the video shows a slow movement of the person's head and hands. So camera might be static, but the subject moves. Wait, the first frame is the person's side, then second frame head moves a bit. So the camera is static, but the subject moves. So camera perspective is close-up, static. But need to check. The instruction says "conclude with the camera perspective and movement". So like "close-up, static" or "close-up, slight pan".

Let me rephrase. A single person in a dark shirt plays a flute, their fingers moving across the keys as they breathe into the mouthpiece. The person’s head turns slightly to the right. Background is dark and blurred. The camera captures a close-up profile of the person with minimal movement.

Wait, but need to keep it concise. Let's check the key points:

- Subject: 1 person, dark shirt, playing flute (key motion)
- Chronological: starts playing, hands move, head turns
- Appearance: dark shirt, flute (no color, since B&W)
- Spatial: no other objects, so just the person in frame
- Background: minimal, dark
- Camera: close-up, static or slight movement? The frames show the person's profile shifting slightly, so maybe the camera is static, but the subject moves. So camera perspective is close-up, static.

Putting it all together:

A person wearing a dark shirt plays a flute, fingers moving across the instrument's keys while their head turns slightly. The background is dark and indistinct. The camera maintains a close-up profile view with minimal movement.

Wait, is the head turning? In the frames, the person's head moves from one side to another. So that's part of the motion. Let's make sure it's chronological. The video starts with the person playing, then head turns, fingers moving. So sequence is: playing, head turns, fingers adjusting.

Yes. So the caption should mention that. Also, rule b: mention appearance and number. Number: 1 person. Appearance: dark shirt, flute.

So final caption: A single person in a dark shirt plays a flute, fingers moving over the keys and head turning slightly as they perform. The background is dark and indistinct. The camera captures a close-up profile of the person with static perspective.

Wait, but "static perspective" might not be right.

The person (flute player) and the flute are moving; the person's hands and body show subtle motion from playing the flute.

Background is static (wall and ornament remain fixed). No ambient environmental motion (fire, water, smoke, wind) observed.


Two individuals interact in a snowy landscape: one person in a dark purple jacket kneels while assisting another standing person wearing a dark green and yellow jacket with ski poles. The standing person raises both arms upward in a gesture. The background features a vast snow expanse with distant mountains. The camera remains stationary throughout.

Two people are present: one seated (relatively static) and one standing. The standing individual exhibits arm movements (e.g., raising arms, gesturing) and slight shifts in posture, indicating deliberate motion from physical forces (locomotion/limb movement).

The background consists of a static snowy landscape with no visible fluid motion, fire, or wind-driven effects. The background elements (snow, horizon) do not exhibit uniform shifting.


A white piping bag applies white frosting rosettes to the sides of a round brown chocolate cake, moving clockwise around the cake's perimeter. The cake sits on a white plate atop a red cloth with white patterned designs. The piping bag's tip deposits smooth, swirled frosting onto the cake's surface, gradually completing the decorative border. The camera maintains a top-down perspective with slight rotation to follow the piping motion.

A white piping bag (discrete object) is visible on the left side, moving slightly to apply frosting to the cake, indicating physical interaction with the cake's surface.

The red fabric background with white patterns remains static across frames, showing no signs of fluid motion (fire, water, wind) or environmental shifts.


A small child, wearing a dark jacket, light blue jeans, and barefoot, dances energetically in a living room. The child spins and steps around the room, moving near a wooden cabinet and a coffee table. The background includes bookshelves and a television. The camera remains stationary throughout the sequence.

A person is moving through the scene with distinct arm and leg motions, indicating locomotion and physical movement.

Static background elements (bookshelf, furniture, floor) show no uniform shifting; no fire, water, or smoke present.


A woman in a pink top walks left, passing a man in a blue polo shirt and blue cap who holds an object; a crowd of people follows behind them. The camera pans left to track the woman's movement.

The discrete objects (people) are moving: the man in the blue shirt is turning to face the woman, and the woman in the pink shirt is turning her head and body and taking a step. There is also slight movement of the crowd in the background.

The background (trees, building, ground) is static and not shifting. No dominant fluid or environmental motion (fire, water, smoke, wind) is observed.


A person wearing a gray sweater uses a makeup brush on their eye, then adjusts the brush to the eyebrow area while the camera zooms in closely, followed by sparkles appearing over their eyes. The camera shifts from a medium close-up to an extreme close-up of the eye and eyebrow, then to the eyes with visual effects. The background remains a solid turquoise color throughout.

A person's hand is moving across their face, performing a deliberate action (likely makeup application or similar), representing a solid, distinct object in motion due to explicit physical force.

The background is a static teal color with no shifting elements or fluid/environmental motion (fire, water, smoke, wind) detected.


RAW CAPTION: Got it, let's tackle this video caption. First, the main subject is a skier. Let's check the frames. The skier is in motion, going up and down a ramp. Let's see the sequence: the skier starts at the top of the ramp, descends, then maybe does a trick or jumps? Wait, in the video, the skier is moving along the ramp. Let's note the appearance: the skier is wearing a white top, orange pants, and has skis. The skis are on their feet.

Chronological order: The skier is initially at the top of the ramp (frame 0), then moves down, maybe jumps or does a maneuver, then continues down. Wait, looking at the frames: frame 0, the skier is in mid-air? Wait, no. Wait, the first frame [0.0] shows the skier jumping off a ramp. Then [1.4] they're landing, [2.5] moving up again, [3.6] jumping again? Wait, no. Let's check the video sequence.

Wait, the video is a loop? Let me see. The skier starts on the ramp, goes down, then maybe hits a jump and goes up. Wait, the first frame [0.0] shows the skier in mid-air, then [1.4] they land on the ramp, then [2.5] they go up, [3.6] mid-air again, [4.7] landing. So the motion is: skier jumps off the ramp, lands, then jumps again, lands, etc.

Appearance: skier has white top, orange pants, skis. The skis are long, dark. The skier is a person, adult size. Spatial relationships: the ramp is beige, the background has some structures (like a building with a sign, but the rules say minimal background). So background is minimal, but maybe just mention the ramp.

Camera perspective: seems like a fixed camera, maybe from the side, capturing the ramp. No movement mentioned.

Let's structure the caption:

Start with the skier's action. In chronological order: the skier begins by launching off the ramp, descends, lands, then ascends the ramp again, launches into the air, and lands. Wait, the sequence is: 0.0: skier in mid-air (jumping off ramp), 1.4: landing on ramp, 2.5: moving up (probably on the ramp), 3.6: mid-air again (jumping up), 4.7: landing.

So the main action: A skier wearing a white top and orange pants performs a sequence of jumps and landings on a ramp. They launch off the ramp, descend, land, then ascend the ramp, launch again, and land.

Now, check the rules: focus on motion and behavior chronologically. Describe appearance (white top, orange pants), number (one skier). Spatial: on the ramp. Background minimal. Camera perspective: fixed, side view.

Let's draft:

A single skier in a white top and orange pants skis down a ramp, launching into the air, landing, then ascending the ramp to jump again and land. The camera remains stationary, capturing the skier’s movements from a side perspective.

Wait, need to be more precise with the timing. Let's check each frame:

Frame 0: skier is airborne, mid-jump, skis horizontal.

Frame 1.4: skier lands on the ramp, skis on ground.

Frame 2.5: skier is moving up the ramp (maybe after landing, continuing up).

Frame 3.6: skier is airborne again (jumping).

Frame 4.7: skier lands again.

So the sequence is: jump off ramp, land, then jump again.

So the caption: A single skier in a white top and orange pants performs a jump from the ramp, lands, then launches into the air again, and lands. The skier maintains balance on the skis throughout, with the camera fixed in a side view capturing the motion.

Check for brevity and chronological order. Let's refine:

A skier wearing a white top and orange pants descends a ramp, launches into the air, lands, then ascends the ramp to jump again and land. The camera remains stationary, capturing the sequence from a side perspective.

Yes, that's concise. Checks all rules: motion chronologically, appearance (white top, orange pants), spatial (ramp), camera (stationary, side view). Background minimal (ramp is the main element, background structures are not essential).

A person in dark clothing shears a white sheep's wool, moving shears along the sheep's body as fleeces fall to the ground. The sheep stands with its legs held by the person, who adjusts its position during shearing. The scene occurs indoors with a wooden floor and a growing pile of shorn wool to the right of the sheep. The camera maintains a stationary, close-up perspective with a slight shake.

A person is actively using a tool to manipulate insulation material on a wall, with clear physical motion of the body and hands.

Three children, two in colorful dresses (one blue, one pink) and one in red, walk with arms outstretched across a pink-brick courtyard, followed by additional children in similar attire joining from the right and moving toward the left; the group runs toward a doorway as the camera pans left to follow their motion.

Children are moving independently via locomotion (running, jumping), with distinct bounding boxes tracking their trajectories.

No shifting background elements or fluid/environmental motion (fire, water, smoke, wind) observed; static walls and structures remain consistent across frames.


RAW CAPTION: Got it, let's tackle this video caption. First, I need to look at the frames. The video is a night scene with two people. The timestamp is 2013-03-31 21:58:39, so it's nighttime. There's a silver minivan and a pink pickup truck in the background. The main subjects are two people.

First, the person in the foreground: they're walking towards the van. Let's check their appearance. They have a jacket, maybe gray, and pants. Then there's another person in the background, wearing a white jacket, walking towards the first person.

Chronologically: the first person (closer to the van) starts moving, then the second person comes from the right side of the frame. They walk towards each other. Wait, in the frames, the first person is moving from right to left? Wait, frame 0: the person is near the van, then in frame 1, they walk towards the center. Then the second person (in white) starts walking from the right side towards the first person.

So step by step: the person in the foreground (gray jacket, pants) walks from the right side towards the van, then turns left. The person in white walks from the background (near the pickup truck) towards the first person. They meet, then the first person turns and walks away. Wait, no, let's check the frames.

Frame 0: two people. Person A (foreground) is near the van, person B (background) is standing. Then in frame 1, person A walks towards the center, person B starts walking towards person A. Frame 2: person B is closer to person A, they seem to interact. Frame 3: person A turns and walks away, person B follows. Wait, maybe they are walking together? Or person B approaches person A, then they walk together.

Wait, the first person (A) is moving from right to left in the frame. Let's check coordinates. The van is on the left, pickup is behind. The person A is on the right side of the van, then walks towards the center, then turns to go towards the building. Person B is on the far right, walking towards the left, towards person A.

So the main subjects: two people. Person A: gray jacket, pants, moving from right to left, then turns. Person B: white jacket, walking from right to left towards person A.

Spatial relationship: person B is behind person A initially, then approaches from the right.

Chronological order: At 0s, person A is near the van's front, person B is standing near the pickup. Then person A walks left, person B starts walking towards person A. They meet, then person A turns and walks towards the building (right side of the frame), and person B follows. Wait, frame 4: person A is now on the right side, walking towards the building. Person B is behind them.

So the sequence: two individuals, one in gray (person A) and one in white (person B), are in a parking lot at night with vehicles. Person A moves from the right side of the frame towards the van, then turns left and walks towards the building. Person B walks from the background towards person A, catches up, then follows person A towards the building. The camera is fixed (no movement, top-down view, night scene). Background has the van and pickup truck, but minimal description.

Now, the caption needs to be concise, chronological. Let's structure it:

At night, two people walk in a parking lot. A person in gray clothing walks from the right towards a silver van, then turns left toward the building. Another person in white clothing walks from the background toward the first person, catches up, and follows them toward the building. The camera is static, overhead.

Check rules: focus on motion and behavior, chronological. Mention appearance (gray, white), number (two people), spatial (right, background). Background minimal. Camera perspective: static, overhead (CAM06 label suggests it's a camera feed, so top-down).

Let's draft:

"Two people are visible in a nighttime parking lot. A person in gray clothing walks from the right side toward a silver van, then turns left and moves toward a building. A second person in white clothing walks from the background toward the first individual, meets them, and follows toward the building. The camera remains stationary, providing a top-down view."

Check if it's concise. Maybe shorten: "At night, two people interact in a parking lot: a gray-clad person walks from the right toward a silver van, then turns left toward the building; a white-clad person walks from the background toward them, catches up, and follows. The camera is

Two people: one in blue suit interacting with the van (repetitive motion, possibly pushing or shoveling), and another in white walking towards the van then stopping.

Background elements (van, building, ground) are static with no uniform shifting. No fluid or environmental motion (e.g., fire, water, wind) observed.


RAW CAPTION: Got it, let's tackle this. First, the video shows a speedboat moving on water. There are two people in the boat, right? The boat is creating a wake. Then, there's a person in the water—maybe being towed or something. Wait, the first frame has a person in the water, but as the boat moves, that person might be getting pulled. Let's check the timestamps.

Frame 0: Boat is moving, person in water left, two red buoys. Frame 1: Boat gets closer, person in water is still there. Frame 2: Boat is closer, person in water is maybe being towed. Frame 3: Boat is even closer, person is still there. Frame 4: Boat is moving past, person is in the water. Frame 5: Boat is almost out of the frame, person is still there.

Wait, the main subjects: the speedboat (dark color, two people inside), and a person in the water (wearing a dark outfit, maybe a wakeboarder). The boat is moving forward, creating a wake. The person is in front of the boat? Or to the side? In the first frames, the person is to the left of the boat. As the boat moves, the person is being pulled behind? Wait, in water skiing or wakeboarding, the person is towed by the boat. So the person is being pulled by the boat, moving in the same direction.

Let's outline chronologically: At the start, the speedboat is moving forward on the water, creating a wake. There are two red buoys visible. A person is in the water to the left of the boat, likely being towed by the boat. As the video progresses, the boat moves closer to the camera, the person remains in the water, positioned to the side (left) of the boat, and the wake intensifies. The boat passes by the buoys, and the person stays in the water, possibly engaging in water sports. The background has trees but minimal detail.

Now, appearance: Speedboat is dark, two people (can't see details, just silhouettes), person in water is wearing dark clothing, maybe a wetsuit. The buoys are red. Spatial: Person is to the left of the boat initially, then as the boat moves, the person is still in the water. The camera is moving towards the boat, tracking its motion as it approaches and passes. Wait, in the frames, the camera is getting closer to the boat, so the camera movement is a forward pan or tracking the boat.

Wait, the video starts with the boat moving away from the camera? Wait, no. The first frame shows the boat approaching, because in frame 0, the boat is a bit distant, then in frame 1, it's closer, frame 2, closer, etc. So the camera is stationary, and the boat is moving towards it. Wait, but in the last frame, the boat is moving past. Wait, the boat starts at a distance (frame 0), then moves forward towards the camera (frames 1-5), so the camera is fixed, and the boat is approaching.

Wait, the description says: "a person in the water" — probably a wakeboarder or water skier being towed. So the person is attached to the boat, moving with it.

Let's structure the caption:

- Initially, a dark-colored speedboat with two people aboard moves forward on the water, creating a wake. A person in dark clothing is visible in the water to the left of the boat, likely being towed. Two red buoys are present on the water's surface. As the boat progresses, it moves closer to the camera, the wake intensifies, and the person remains in the water beside the boat. The camera remains stationary, capturing the boat's approach and movement through the water.

Wait, need to check the rules. Focus on motion and behavior chronologically.

Chronological order: The boat moves towards the camera, creating a wake. The person in water is being towed (since they are moving with the boat). The boat passes by, and the person stays in the water.

Appearance: Speedboat is dark (maybe black or dark blue), two people (can't see details, just silhouettes), person in water is dark-colored outfit, red buoys.

Spatial: Person is to the left of the boat initially, as the boat moves, they stay in the water.

Camera perspective: The camera is stationary, capturing the boat's approach and movement, so the camera doesn't move, but the boat comes closer.

Wait, in the frames, the boat starts at a distance, moves forward (towards the camera), so the camera is fixed. The person is being towed by the boat.

Let me

A boat with two people on board is moving towards the camera. The boat's motion is due to propulsion, and the people remain stationary relative to the boat.

The background consists of static trees and water with gentle ripples. The water's motion is subtle and non-dominant compared to the boat's movement. No significant fluid or wind-driven motion dominates the scene.


Multiple workers in bright yellow and orange safety vests move and work on a concrete foundation, positioning rebar and materials; additional workers enter from the right, spreading across the structure while others adjust their positions; camera maintains a static top-down perspective throughout.

Workers in high-visibility vests are moving across the construction site, walking and interacting with materials on concrete slabs.

The background (dirt ground, wooden supports, distant vehicles) shows no shifting or fluid motion; no fire, water, smoke, or wind is visible.


RAW CAPTION: Got it, let's tackle this. The video starts with a boxing ring. There are two fighters. The one in lighter gear, maybe white or light gray, and the other in darker, like black. First, the lighter one is standing, then maybe the darker one moves. Wait, the sequence: first frame shows both in the ring. Then the darker one (maybe the one with black shorts) is on the ground. Wait, no, in frame 0, the lighter one is standing. Then frame 1, the darker one is moving. Wait, let's watch the frames:

Frame 0: Both fighters in the ring, one is standing (lighter), the other (darker) is maybe near the ropes. Then frame 1: the darker one is attacking, maybe a tackle, and they both go down. Frame 2: they're on the mat. Frame 3: the lighter one is on top, maybe pinning the darker one. Frame 4: still grappling. Then frame 5: the screen turns to yellow text "FULL" maybe.

So chronological: two boxers in a ring. The boxer in darker attire (black shorts) engages the boxer in lighter attire (light shirt/shorts). The darker boxer moves toward the lighter one, causing both to fall to the mat. They grapple on the floor, with the lighter boxer gaining control, pinning the darker one. The scene ends with a yellow text overlay.

Wait, but the rules say to focus on motion and behavior. So: In a boxing ring, two fighters—one in lighter clothing (e.g., white) and one in darker clothing (e.g., black)—engage. The darker fighter advances, leading to both falling to the blue mat. They wrestle on the floor, with the lighter fighter maintaining a pinning position over the darker one. The camera remains stationary, capturing the action from a slight overhead angle.

Wait, check the frames: frame 0: the darker one is near the ropes, lighter one is standing. Then frame 1: darker one moves, maybe a punch or tackle. Then they both go down. Frame 2: they're on the floor. Frame 3: lighter one is on top, pinning. Frame 4: still wrestling. Then frame 5: the yellow text.

But need to mention spatial relationships. The ring is the setting. The boxers are in the ring, with ropes. The background has spectators, but per rules, keep background minimal. So focus on the boxers.

Appearance: two boxers, one in lighter (white/grey) attire, the other in darker (black) attire. Their size: probably similar, both standing initially, then one (darker) attacks, causing a fall.

Chronological: The boxer in darker clothing initiates contact with the boxer in lighter clothing, resulting in both falling to the mat. The lighter-clothed boxer then pins the darker-clothed boxer to the blue ring floor. The camera stays fixed, providing a top-down view of the ring during the action.

Wait, the camera movement: the video shows the action, probably a fixed camera angle. The last frame has yellow text, so the camera might not move during the fight.

Let me structure it:

In a boxing ring, two fighters—one in light-colored attire and one in dark-colored attire—engage. The dark-attired fighter advances, leading to both falling onto the blue mat. They grapple on the floor, with the light-attired fighter pinning the dark-attired fighter. The camera remains stationary, capturing the action from an overhead perspective.

Check rules: focus on motion, chronological. Yes. Mention appearance (light and dark attire), number (two). Spatial: on the mat, pinning. Background: ring, minimal. Camera: overhead, stationary.

Wait, the frames: frame 0: both in ring, dark one maybe near ropes, light one standing. Frame 1: dark one moves, maybe a tackle, they both fall. Frame 2: lying on mat. Frame 3: light one on top, pinning. Frame 4: still pinning. Then frame 5: yellow text.

So the motion: starts with both standing, dark advances, they fall, light pins dark.

Also, the rules say exclude text recognition. So the "FULL" text is not mentioned, only the action.

Another check: "Briefly describe their appearance and number (color, size, orientation)." So color (light and dark), size (similar, presumably), orientation (standing initially, then prone on mat, then pinning).

So putting it all together:

In a boxing ring, two boxers—one in light clothing and one in dark clothing—begin facing each other. The dark-clad boxer moves forward, causing both to fall onto the blue mat. They wrestle

Two boxers are moving: one in white and one in black, engaging in physical combat (punching, grappling, falling).

The background (boxing ring ropes, audience) is stationary. No fire, water, smoke, or wind motion is observed.


A checkers board with red and white pieces is shown. A hand moves a red piece forward, followed by another hand moving a white piece forward. The camera maintains a top-down perspective throughout, capturing the board and hands' movements without background details.

Human hands are moving discrete solid objects (chess pieces) on the board, demonstrating explicit physical manipulation of the pieces.

No shifting background elements; no fluid/environmental motion (fire, water, smoke, wind) observed. The chessboard and surrounding surface appear stable with no uniform background displacement.


A hand pours red sauce from a yellow-capped bottle over raw chicken pieces in a large metal pot, then uses fingers to mix the sauce into the chicken, distributing it evenly. The camera remains in a close-up perspective, focusing on the pot and mixing action with minimal movement.

A hand is actively stirring the chicken and sauce mixture in the pot. The hand is the discrete solid object causing the motion of the chicken and sauce pieces.

No shifting background elements; no fire, water, smoke, or wind motion observed. Background (wooden surface and green object) remains static throughout.


A person with long dark hair is shown in a close-up, slowly shifting their gaze upward, then to the left, and back toward the camera. The camera remains fixed throughout, capturing the individual's subtle head movements against a softly lit background with circular decorative elements.

A person (girl) is moving their head and eyes, with visible shifts in gaze direction.

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


A person's hairy arm is gripped and adjusted by another arm in a close-up shot; the gripping arm shifts position slightly while maintaining hold on the lower arm, which remains extended horizontally. The arms are positioned side by side against a light background, with the gripper arm on the left. The camera remains static and focused on the interaction between the arms.

Two hands are moving a cylindrical rolling pin back and forth on a flat surface; the motion is controlled by the hands and the rolling pin rolls due to manual action.

The background is a static countertop with no shifting or fluid motion (fire, water, wind).


RAW CAPTION: Got it, let's break down the video. First, the main subject is a person sitting on the ground, playing an accordion. The person is wearing a white shirt and blue jeans, with brown shoes. The accordion is black and white. There's an open suitcase next to them, probably for collecting tips. The setting is outdoors, under a tree with some chairs and rocks in the background. The camera seems to be stationary, maybe a slight pan or just fixed. Let's check the rules: need chronological order of motion. The person is seated, playing the accordion, so the action is continuous. Spatial relationships: the suitcase is to the left of the person. Background is minimal, just trees and chairs. Camera perspective is probably eye-level, since it's a standard shot. Let's structure the caption.

Start with the main subject: a person sits on the ground, plays accordion. Describe appearance: white shirt, blue jeans, brown shoes. The accordion is black and white. Suitcase is open, next to them. Then the background elements briefly, but minimal. Camera is stationary, maybe slight movement? The frames show maybe a slight pan, but the problem says "slight shake" maybe. Wait, the video description says "the camera perspective and movement" so need to mention that. Looking at the frames, the camera might be static but perhaps a slight pan left. Wait, the user says "DO NOT output your reasoning", but we have to follow the rules.

Let me put it all together:

A person in a white shirt, blue jeans, and brown shoes sits on the ground playing a black and white accordion. An open dark suitcase lies to their left on the paved surface. The scene is set outdoors under a tree with wooden chairs and rocks in the background. The camera remains stationary with minimal movement.

Wait, check rules: "Conclude with the camera perspective and movement (e.g., top-down, pan left, slight shake)." So need to specify that. The video frames might show the camera panning left slightly? Let's see. The frames: first frame, second, etc. Maybe the camera is panning left. Wait, but the instruction says to think internally but not output reasoning. So based on the video, the camera movement: the user's example might have a slight pan. Let's check the rules again. "Conclude with the camera perspective and movement".

So the caption should end with camera movement. Let's see:

"A person in a white shirt, blue jeans, and brown shoes sits on the ground, playing a black and white accordion. To their left rests an open dark suitcase on the paved surface, with wooden chairs and rocks visible in the background under a tree. The camera remains mostly stationary with a slight pan to the left."

Wait, but need to be concise. Let's check the example: "Focus primarily on the motion and behavior of main subjects... chronological order."

The main subject is playing the accordion, so the motion is playing. So the caption should start with the person sitting and playing.

Let's write:

A person wearing a white shirt, blue jeans, and brown shoes sits on the ground, playing a black and white accordion. An open dark suitcase lies to their left on the paved surface. The scene is outdoors under a tree with wooden chairs and rocks in the background. The camera maintains a stationary perspective with minimal movement.

Wait, but the rules say "Keep background descriptions minimal unless essential for understanding motion." The background has chairs and rocks, but maybe essential for the setting? The tree is there, but not sure. But the user says to include spatial relationships if relevant. The suitcase is to the left, which is relevant.

Also, the person's position: sitting on the ground, next to the suitcase.

Let's make sure it's chronological. The person is sitting and playing, so the action is continuous.

Final check:

- Motion/behavior: person playing accordion (continuous, so in chronological order, it's the ongoing action).

- Appearance: white shirt, blue jeans, brown shoes; accordion is black and white.

- Spatial: suitcase to the left, person on ground, background has tree, chairs, rocks.

- Camera: stationary, maybe slight pan.

Wait, the problem says "Conclude with the camera perspective and movement". So the last part should be about the camera.

So putting it all together:

A person dressed in a white shirt, blue jeans, and brown shoes sits on the ground, playing a black and white accordion. An open dark suitcase rests to their left on the paved surface, with wooden chairs and rocks visible under a tree in the background. The camera remains stationary with slight movement.

But need to be concise. Let's trim down:

A person in a white shirt, blue jeans, and brown shoes sits on the ground, playing a black and white accordion. An open dark suitcase lies to their left on the pavement. The scene

The person (a discrete solid object) is moving their hands and body to play the accordion, causing minimal but distinct motion.

The background is static with no shifting or environmental fluid motion (e.g., fire, water, wind).


The video begins with two workers: one in a beige jacket and blue pants, the other in a white helmet and red vest, standing on a paved area. As the camera pans left, additional workers in orange safety vests and blue helmets enter the frame, moving across the site with long-handled tools. The workers’ coordinated motion includes running and adjusting tools, while a bright light appears in the background, illuminating the scene. The camera continues its leftward pan, capturing the activity on the wet, paved ground with distant trees visible beyond the work zone.

Multiple individuals moving across the scene (walking, running) with visible locomotion; no fluid or gaseous motion dominating the frame.

No significant background shift observed; trees and ground remain static. No fire, water, or smoke visible, ruling out ambient environmental motion.


A person in green shorts and a black t-shirt kneels against a concrete wall on a stone surface. They initially adjust their hands, then clasp them together while shifting their kneeling position and leaning forward slightly. The camera maintains a static medium angle with minimal movement.

A person (solid object) moves from a kneeling to a standing position due to their own locomotion.

Concrete wall background is static; no fire, water, smoke, or wind observed.


RAW CAPTION: Got it, let's break this down. The video starts with a child sitting in a car seat, right? The child is wearing a white and blue sleeveless shirt, and they're holding a blue object, maybe a toy or a bottle. Then the child stands up? Wait, no, the next frame shows them standing, holding the blue object, and putting it to their mouth, like drinking or sucking. Then they lower it. Wait, the first frame is sitting, second frame they're standing, third they're drinking from the blue object, fourth they're lowering it, fifth they're holding it again.

Wait, let's check the frames. Frame 0: child seated, hands on blue object. Frame 1: child standing, same shirt. Frame 2: child drinking from blue object. Frame 3: child lowering the blue object. Frame 4: child holding it with both hands. Frame 5: child holding it again, maybe turning it.

So chronological: The child, wearing a white and blue sleeveless shirt with text (but we can't mention text per rule f), is first seated in a car seat, holding a blue object. Then stands up, brings the blue object to their mouth, drinks, lowers it, and holds it again.

Appearance: child is small, wearing white and blue sleeveless shirt, blue backpack maybe? In frame 1, there's a blue backpack on their back. Background has car seats and plates on the floor.

Spatial: The child is seated first, then stands up. The blue object is in their hands, brought to mouth.

Camera perspective: seems like a top-down or close-up, maybe handheld as it's a bit shaky. The camera moves a bit, following the child's movement.

Need to follow the rules. No text recognition, so ignore any text on the shirt. Focus on motion: seated → standing → drinking from blue object → lowering → holding.

Let's draft:

A small child wearing a white and blue sleeveless shirt stands up from a car seat, holding a blue object. They bring the object to their mouth, drink, then lower it while holding it with both hands. The background shows car seats and plates on the floor. The camera remains close to the child with slight movement.

Wait, need to check rules:

a) motion and behavior chronological: seated (frame 0), then standing (frame1), drinking (frame2), lowering (frame3), holding (frame4-5). So start seated, then stands, drinks, lowers, holds.

b) appearance: child, small, white and blue sleeveless shirt, blue backpack (maybe, but not sure if essential). Number: one child.

c) spatial: seated in car seat (first), then stands up, so in front of the car seat maybe? But background is car interior.

d) camera: top-down? Wait, the first frame is a bit top-down, but then it's a close-up. The description says "slight shake" maybe.

e) background minimal: car seats and plates, but just mention if essential. The plates are on the floor, but maybe not essential.

f) exclude text recognition, so the shirt has text but we don't mention it.

g) don't output reasoning.

So revised:

A small child in a white and blue sleeveless shirt, wearing a blue backpack, starts seated in a car seat holding a blue object. They stand up, bring the object to their mouth, drink, then lower it while holding it with both hands. The background shows a car interior with seats and plates. The camera follows the child with slight movement.

Wait, but rule e says minimal background descriptions. So maybe just "car interior" or "car seats".

Check rule c: spatial relationships. "Seated in a car seat" → "stands up" so they were in the car seat, then stand.

So:

A small child wearing a white and blue sleeveless shirt sits in a car seat holding a blue object. They stand up, bring the object to their mouth, drink, then lower it while holding it. The background includes a car interior with seats. The camera remains close to the child with slight movement.

But need to make it a paragraph. Let's structure it chronologically.

The child, dressed in a white and blue sleeveless shirt, begins seated in a car seat holding a blue object. They then stand up, lift the object to their mouth, drink from it, and lower it while gripping it with both hands. The background features car seats and plates on the floor. The camera maintains a close perspective with minimal movement.

Wait, "minimal movement" but the description says "slight shake" maybe. But the problem says "conclude with camera perspective and movement". So "close-up, slightly shaky".

Hmm. Let's look at the frames: the first frame is a bit top

Child is moving hands and head to open bottle cap, drink, and manipulate bottle; actions are discrete and driven by physical forces.

No shifting background; no fire, water, smoke, or wind-driven motion observed.


Two light-skinned hands use a metallic crochet hook to pull orange yarn through loops, progressively forming a crocheted stitch; the camera maintains a close-up, steady perspective centered on the hands and yarn against a dark background.

Discrete objects include the hands, knitting needles, and yarn. The hands perform precise, repetitive motions (gripping, pulling, looping) to manipulate the yarn and needles, driven by intentional physical forces.

The background is a solid black surface with no visible environmental elements (e.g., no fire, water, smoke, or wind). The black background remains static and shows no uniform shifting, ruling out ambient environmental motion.


The video opens with a black screen, then transitions to a close-up of a person’s hands playing a white electric guitar. The individual wears a light blue shirt with a spider design, and their fingers move rhythmically across the fretboard, pressing and strumming strings. The background features white doors, and the camera remains stationary, focusing tightly on the hands and instrument throughout.

Discrete solid objects: person's hands moving on guitar strings/fretboard (strumming, fretting actions) and the guitar body (subtle vibrations from playing).

Background (wall, door frame) is static with no shifting or environmental motion (fire, water, smoke, wind) detected. No fluid or gaseous elements visible.


The video opens with a close-up of tall brown cattails against a snowy, icy backdrop. A person wearing blue pants and black boots steps forward onto the cracked ice, their movement causing small splinters of ice to break off. The camera then pulls back, revealing the person walking away across the expansive icy field, with sparse brown reeds and bare trees in the distant background. The camera maintains a steady, slightly elevated perspective throughout, tracking the individual’s progress as they move further into the open space.

A person wearing blue pants and boots is moving (walking) across the frozen terrain, with clear locomotion visible in the lower frames.

The background consists of static elements (dry grasses, frozen landscape) with no significant environmental motion (e.g., wind, flowing water, smoke). No fire, water, or wind dominates the scene.
