A person in a white dress shirt and purple tie adjusts the tie by pulling it upward and tightening the knot while standing in front of a door and a framed underwater-themed picture. The camera remains stationary throughout.

A person (discrete solid object) moves their hands and body to adjust a necktie, with visible physical motion due to manual manipulation.

Background elements (painting, door) show no uniform shifting; no fluid or environmental motion (fire, water, smoke, wind) present.


RAW CAPTION: Okay, let me tackle this video caption request. First, I need to understand what the user is asking for. They want a concise, chronological paragraph describing the video, following specific rules.

Looking at the video description: it's a tractor with a red snowblower in a snowy environment. The tractor is moving, kicking up snow. There's a person in the background, maybe two people. The camera seems to follow the tractor.

The rules say focus on motion and behavior of main subjects in order. So first, the tractor is moving forward, snowblower spinning. The person in the background is walking. The tractor's color: red snowblower, yellow wheel. Need to mention the motion—snow being blown, the tractor moving through the snow. Spatial relationships: person in the background, maybe left side. Camera movement: seems to pan left as the tractor moves.

Check the rules again: keep background minimal unless essential. The person in the background is maybe not essential, but since they are moving, maybe mention them briefly. Wait, the user says "briefly describe their appearance and number". So the people: two people in the distance, walking. But the main subject is the tractor. Need to structure chronologically: start with the tractor moving, then the person walking.

Wait, the video starts with the tractor's snowblower working, then the camera moves left, showing the person in the background. So the order would be: tractor moving forward with snowblower, snow being ejected, then camera pans left to show people walking in the distance.

Need to mention the red snowblower, yellow wheel. The snow is being blown to the side. The people are in the background, walking. Camera perspective: the initial shots are close-up of the tractor, then pans left to show the people. But the video description shows the camera moving left as the tractor moves. So the camera is following the tractor, panning left.

Wait, in the video description, the first few frames show the tractor from the side, then the camera moves left, showing the person. So the camera movement is panning left as the tractor moves. So the caption should mention the camera's movement as panning left.

Background: snowy residential area, houses, trees. But rule says minimal background unless essential. So mention the snowy landscape briefly, but maybe just "snow-covered landscape" without details.

Let me structure the paragraph:

A red snowblower attached to a green tractor with yellow wheels moves forward through deep snow, ejecting snow to the left. As the tractor advances, the snowblower spins rapidly, sending snow particles airborne. In the background, two figures walk along a snow-covered road. The camera pans left, tracking the tractor’s movement while maintaining a close perspective on the snowblower’s operation.

Check the rules:

a) Motion and behavior in chronological order: tractor moving, snowblower spinning, people walking. Correct.

b) Appearance: red snowblower, yellow wheel, two people. Correct.

c) Spatial: people in background, snowblower to left of tractor? Wait, the snow is ejected to the left. The people are behind or to the left? The description says "two figures walk along a snow-covered road" in the background, so maybe behind the tractor. So "in the background, two figures walk along the road."

d) Camera perspective: close-up of tractor, then pans left. The caption says "camera pans left, tracking the tractor’s movement while maintaining a close perspective on the snowblower’s operation." That covers it.

e) Background minimal: "snow-covered road" is enough.

f) Exclude text, etc. No text in the video.

g) No internal reasoning.

Check conciseness. Maybe "A red snowblower attached to a green tractor with yellow wheels moves forward through deep snow, ejecting snow to the left. The snowblower spins rapidly as the tractor advances, sending snow particles airborne. In the background, two figures walk along a snow-covered road. The camera pans left, tracking the tractor’s movement while maintaining a close perspective on the snowblower’s operation."

Wait, the video starts with the tractor moving, so "moves forward through deep snow" is the first action. Then the snowblower is spinning. Then the people walking. Camera pans left.

Is "ejecting snow to the left" accurate? The video shows the snow being thrown to the side, maybe left side relative to the tractor's direction. So that's correct.

Need to make sure it's chronological: first the tractor moving, then the snowblower action, then the people walking. The camera movement is part of the sequence.

I think that's covered.
</think>

<caption_output>A red snowblower attached to a green tractor with yellow wheels advances through deep snow, spinning rapidly to eject snow to the left. As the tractor

A tractor is moving forward, displacing snow as it travels, with its red snowblower attachment actively engaged in clearing snow from the ground.

No shifting backgrounds or fluid/environmental motion observed; snow-covered ground and distant trees remain static throughout the sequence.


A person runs toward a central tumbling mat in a dark indoor gym, performs a jump with arms raised, lands on the mat, and then exits the mat area. The individual is silhouetted against the dimly lit background, with spatial focus on their movement across the mat. The camera remains static, capturing the sequence from a frontal perspective with minimal background detail.

A single discrete solid object (a person) is performing tumbling motions (flips, rolls) on the mats, with clear, controlled physical movement.

The background (walls, floor markings, and fixed structures) remains static throughout the sequence. No fluid or environmental motion (fire, water, smoke, or wind) is observed.


A hand manipulates a white, fluffy substance in a close-up shot, pressing and folding it. The scene then widens to reveal a person in a white shirt using a tool to shape the substance on a wooden board, with a yellow bowl positioned to the left. Green plants are faintly visible in the background. The camera shifts from a tight close-up to a medium shot.

Hands moving and placing white substance (e.g., rice) on a board.

No shifting background or fluid/environmental motion; background in the second scene is static kitchen items, and first scene has no visible background.


RAW CAPTION: Got it, let's tackle this captioning task. First, I need to understand the video. The main subject is a young child, a girl, sitting on a bed. She's wearing a sleeveless white top with a pattern and light-colored shorts. She's holding a blue pen and writing or drawing in a book. The book has text and some images.

Let's break it down chronologically. The video starts with her writing, then she moves the pen, maybe turns the page or shifts her position. She's sitting cross-legged on the bed. The background has a purple pillow and a wooden cabinet with a mirror, but I need to keep background minimal.

Appearance: She has curly brown hair, is a small child. The pen is blue. The book is open, with text and images. Her actions: writing, then lifting the pen, maybe turning the page or adjusting the book.

Spatial relationships: She's on the bed, the book is in front of her. The mirror in the cabinet reflects part of the room, but maybe not necessary.

Camera perspective: The video seems to be shot from a fixed angle, slightly shaky maybe? The description says "slight shake" in the rules, so check if the camera moves. Looking at the frames, the camera might have a slight movement, not static.

Need to follow the rules: focus on motion and behavior in order. Start with her writing, then moving the pen, adjusting the book. Mention her appearance (color, size, orientation) but briefly.

So the caption should go like: A small child with curly brown hair, wearing a sleeveless white patterned top and light shorts, sits on a bed. She holds a blue pen, writing in an open book with text and images. She moves the pen across the page, lifts it, and adjusts the book's position. The camera maintains a slightly shaky, front-facing angle throughout, capturing her actions against a bed with a purple pillow and a wooden cabinet in the background.

Wait, need to make it concise. Let's see. Chronological order: she is writing, then shifts pen, maybe turns page.

First, the main actions. Let's structure:

A young child with curly brown hair, dressed in a sleeveless white top and light shorts, sits cross-legged on a bed. She holds a blue pen, writing on an open book with printed text and illustrations. She then lifts the pen, adjusts the book's position, and continues writing. The camera remains steady but with slight movement, capturing her from a frontal perspective against a bed with a purple pillow and wooden furniture.

Check the rules: exclude text recognition (so no mentioning "text" but maybe "printed text" is okay as it's not the text content). Named characters: no, so okay. Stylistic analysis: no.

Make sure it's chronological: start with her writing, then moving pen, adjusting book. Mention appearance: curly hair, white top, light shorts, blue pen. Spatial: on the bed, book in front. Background minimal: purple pillow, wooden cabinet. Camera: front-facing, slight shake.

Let me draft:

A young child with curly brown hair, wearing a sleeveless white patterned top and light shorts, sits cross-legged on a bed. She holds a blue pen, writing on an open book with text and images. She lifts the pen, adjusts the book, and resumes writing. The camera maintains a frontal perspective with slight movement, capturing the child against a bed with a purple pillow and wooden furniture in the background.

Wait, "slight movement" is part of the camera perspective. Need to specify. Also, "open book with text and images" is okay. Let's check length. Concise. Let's trim.

A small child with curly brown hair, wearing a sleeveless white top and light shorts, sits on a bed, writing with a blue pen in an open book. She lifts the pen, adjusts the book, and continues writing. The camera remains steady but slightly shaky, capturing her from the front against a bed with a purple pillow and wooden furniture.

Wait, the rules say "minimal background descriptions unless essential." So maybe "purple pillow and wooden cabinet" is essential? Maybe. Let's see.

Final check: chronological (writing, lift pen, adjust book), appearance (hair, clothes, pen), spatial (on bed, book in front), camera (frontal, slight shake), background minimal.

Another version:

A young child with curly brown hair, dressed in a sleeveless white top and light shorts, sits cross-legged on a bed. She writes with a blue pen in an open book, then lifts the pen, adjusts the book's position, and continues writing. The camera maintains a frontal perspective with slight shake, capturing the scene against a bed with a purple pillow and wooden cabinet.

That's concise. Let's see if it meets

The girl is moving her hand and arm to write in a book; her body and head also exhibit slight movements.

The background (wooden cabinet, bed) is static; no fire, water, smoke, or wind motion observed.


A baby in a pink outfit with a green bib sits in a high chair, holding a large red watermelon slice with green rind. The baby brings the watermelon toward their mouth, then lifts their head and looks up, appearing to smile. The baby remains seated in the high chair, which has a purple backrest; the background features floral wallpaper. The camera is stationary with a slight shake, capturing the scene from a front perspective.

The baby in the high chair is moving: turning head, moving hands while holding the watermelon slice.

The background (floral wall and furniture) is static with no shifting or fluid motion. No fire, water, or wind is present.


A man in a gray long-sleeve shirt and dark pants lifts and swings a child in a white shirt and dark pants in a circular motion, gradually lowering the child to the ground. To his left, a man in a red jacket and dark pants holds a rope, and to his right, a woman in a red jacket and gray pants also holds a rope. The camera remains stationary throughout the sequence.

Discrete solid objects (people) are moving: the central figure performs kicking motions and walks, while others adjust positions.

Background elements (buildings, cars, tree) show no uniform shifting; no significant fluid/environmental motion (fire, water, smoke, or wind) is present.


A woman in a red top and black pants stands before a chalkboard with stacked colored rectangles, holding a glass. A boy in a white shirt and dark pants approaches her from the left, taking the glass. She gestures with her hands while he holds the glass. The camera remains stationary, capturing the interaction in a classroom setting with students seated in front. Background includes a chalkboard, a white chair, and floral-patterned wall decor.

Two people (red-shirted and white-shirted) exhibit discrete motion: the red-shirted person gestures and interacts with the white-shirted person who moves arms/body during the interaction.

The background (chalkboard, wall, chairs) remains static with no shifting or fluid motion. No fire, water, or wind effects are present.


A person wearing a black shirt and gray pants uses their right hand to repeatedly draw a black-handled knife back and forth across two metallic rods of a black knife sharpener held steady in their left hand on a light green surface. The background features a blue corrugated panel. The camera maintains a stationary close-up perspective focused on the hands and sharpener throughout the sequence.

A person's hand holds a tool (likely a cutter) interacting with a cylindrical object in a holder; the tool moves in a controlled, repetitive motion to cut the object.

Background consists of a static blue corrugated surface with no shifting or fluid motion. No fire, water, smoke, or wind-driven elements observed.


A man in a light-colored shirt and dark shorts stands on a pebbly shoreline near water, holding a shovel. He bends forward, positioning the shovel to dig, then lifts the shovel, shifting his weight. The background shows a calm body of water with a distant horizon. The camera remains static throughout.

A person is actively shoveling sand, with discrete movement of the body, shovel, and sand being manipulated.

Background elements (ocean, horizon) show no significant shifting or fluid motion; no fire, water, or smoke dominance.


RAW CAPTION: Got it, let's break this down. The video starts with a top-down view of a Scrabble board. Then cuts to a person sitting at a table. The person is wearing a patterned sweater and a beanie, holding a tile, then placing it. Wait, first scene: Scrabble board on table, tiles around. Then second scene: person at table, picks up tiles, places them. Need to describe chronologically.

First frame: Top-down view of Scrabble board (multicolored, tiles arranged, some tiles on table). Then the scene shifts to a person (wearing a dark sweater with white patterns, a knit beanie) at a round table. The person picks up a set of tiles, places them down, then seems to interact with something (maybe the tiles). Wait, the video has [0.0] to [5.0] seconds. The first frame is 0.0, then 1.4 shows the person.

So the caption should start with the Scrabble setup, then the person's actions.

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

First part: A Scrabble board with tiles is laid out on a wooden table, surrounded by scattered tiles. Then the scene cuts to a person wearing a dark patterned sweater and a knit beanie, seated at a round table. The person picks up a set of tiles, places them on the table, and then moves their hand toward their face.

Wait, the exact steps: [0.0] is the board. Then [1.4] is the person. So the video starts with the board, then cuts to the person. The person is holding tiles, then places them (maybe arranging?).

Wait the first frame (0.0) shows the board, then [1.4] shows the person. So chronological order: first the board, then the person's actions.

The person is at a table, picks up tiles (from the table), places them down, then maybe gestures.

Need to keep it concise. Also, mention spatial relationships: in the first scene, the board is on a table with tiles around. The second scene, the person is at a table (round), with a window in the background, red wall.

But per rule e: minimal background unless essential. So maybe just "at a table" and "near a window".

Now, the caption should be a paragraph describing motion chronologically.

First: A Scrabble board with colored squares and tiles is shown on a wooden table with scattered tiles. Then, a person wearing a dark patterned sweater and knit beanie sits at a round table, picks up tiles, places them on the table, and gestures with their hand.

Wait, check the exact video: [0.0] is the board. [1.4] is the person. Then [2.5] the person holding tiles, [3.6] placing them down? Wait the video description says:

[0.0] - Scrabble board on table.

[1.4] - person sitting, hand on table.

[2.5] - person holding tiles.

[3.6] - person putting tiles down.

[4.7] - person gesturing.

So the sequence:

1. Top-down view of Scrabble board on wooden table with scattered tiles.

2. Cut to person wearing dark patterned sweater and knit beanie seated at round table; person holds a set of tiles, places them on the table, then gestures with their hand.

Now, describe in chronological order.

Check appearance: person has dark sweater with white patterns, knit beanie. Number: one person.

Spatial: in the first scene, board on table. In the second, person at table (round), with window to the right (background).

But rule e: minimal background. So maybe "at a round table with a window in the background".

But need to be concise.

Also, camera perspective: first scene is top-down. Then the second scene is a medium shot (showing the person from chest up or so). The rules say conclude with camera perspective and movement.

So the caption should end with "Camera begins with top-down view of the board, then cuts to a medium shot of the person."

Wait, the output format says "Conclude with the camera perspective and movement (e.g., top-down, pan left, slight shake)."

So in the caption, describe the camera perspective for each part.

First scene: top-down view.

Second scene: after the cut, camera is at a medium shot.

So putting it all together:

The video opens with a top-down view of a Scrabble board on a wooden table, surrounded by scattered tiles. The scene then transitions to a person wearing a dark patterned sweater and knit beanie seated at a round table, who picks up a set of tiles, places them on the table,

A person's hands move to pick up, manipulate, and place Scrabble tiles on a board; these are discrete, solid objects exhibiting intentional motion.

No shifting background elements or fluid/environmental motion observed. The static background (walls, floor, furniture) remains consistent across frames without uniform movement.


A large muddy off-road vehicle's tire dominates the frame as a person in a green shirt crouches in front of it. The camera pulls back slightly, revealing the vehicle moving slowly through mud, with multiple people surrounding it; one person in dark clothing approaches while another gestures near the tire. The vehicle progresses forward, aided by the group, with the camera maintaining a slight shake and shifting from close-up to a wider angle.

Discrete objects: The off-road vehicle (with spinning tire), the person in green shirt crouching near the tire, and other people assisting (e.g., stepping into frame). The tire spins due to vehicle's engine attempting to move, and people move due to pushing/assisting.

Background is muddy ground and distant vegetation, which is static. No fire, water, smoke, or wind as dominant motion. Mud splashing is a result of tire spinning (discrete object physics) and not an ambient fluid motion.


In a room with several seated individuals around a small table, a person with dark hair and dark clothing enters from the right, walks across the frame in front of the seated group, and exits to the left; camera remains static.

A single person (man) walks from the right to the left across the frame, moving due to his locomotion.

Static background elements (bookshelves, wall) do not shift. No fire, water, or smoke observed.


A person uses a white steam press to smooth a light-colored shirt, moving the press across the fabric with their hands while adjusting the shirt's position. The camera remains focused on the hands and steam press in a close-up view.

A person’s hands manipulate a garment (fabric), showing lifting, folding, and positioning actions.

Background elements (text overlays, wall) are static; no fluid/environmental motion (fire, water, wind) observed.


A worker wearing a blue cap, gray shirt, and dark pants bends to pick up a brick from a pile, then places it onto a gravel bed, while another worker in light gray clothing stands to the right holding a shovel; the camera maintains a stationary top-down perspective throughout the sequence.

Two workers: one bends and manipulates bricks with hands, the other holds a shovel. Their movements involve discrete, deliberate actions (placing bricks, shoveling soil) with visible physical interactions.

Background elements (stone piles, ground, bricks) show no uniform shifting; no visible fire, water, smoke, or wind-driven motion.


Two individuals, one in a yellow shirt and dark shorts, the other in a dark shirt and shorts, interact on a grassy field. The yellow-shirted person moves forward, throws an object, and the dark-shirted person catches it. The yellow-shirted individual then steps back while the dark-shirted person stands in place. The camera remains stationary with a low-angle perspective, capturing their motion against a backdrop of trees and a clear sky.

Two distinct solid objects (people) are moving: the person in the yellow shirt performs dynamic actions (bending, kicking), while the person in the dark shirt remains relatively stationary. The motion of the yellow-shirted individual is driven by explicit physical forces (locomotion, interaction with a ball).

The background elements (trees, grass, distant structures) show no uniform shifting or fluid/environmental motion (fire, water, wind). Static objects like trees and ground remain stable throughout the frames.


A hand holding a red tool moves toward a wooden block positioned under a drilling machine; the drill operates, creating holes in the wood as the hand adjusts the block's position. The wooden block, dark brown with pre-existing holes, sits on a workbench with scattered wood pieces nearby. The camera maintains a close-up, slightly shaky perspective focused on the drilling action and hand movements.

A hand holding a pink plastic tool is moving it across a wooden board in a back-and-forth motion, likely for sanding or smoothing.

The background (workbench, wooden blocks, metal vise) is stable with no shifting or environmental motion (e.g., fire, water, smoke, wind).


RAW CAPTION: Got it, let's tackle this video caption. First, I need to watch the video and note the key elements. The video shows an indoor inflatable play structure. There are kids around it. Let's see the sequence.

In the first frame, there's a child in blue on the purple mat. Then another child in white and blue shorts is seen. Wait, the video starts with the inflatable structure. Let's check each frame.

Frame 0: Inflatable bouncy castle with red, yellow, green. Kids near it. One kid in blue on purple mat. Frame 1: Child in white shirt and blue shorts is moving towards the structure. Frame 2: Same kid is near the slide. Frame 3: Kid is climbing the structure. Frame 4: Kid is on the slide, sliding down. Frame 5: Kid is sliding down the slide.

Wait, the main subject is a child. Let's track the motion. The child starts on the purple mat (frame 0), then moves towards the inflatable (frame 1-2), climbs up (frame 3), and slides down (frames 4-5).

Appearance: The child is wearing white shirt and blue shorts (maybe blue pants). Let's confirm. In the frames, the child is in light-colored top and blue shorts. Maybe "white shirt and blue shorts" for appearance.

Number: One main child, maybe others in the background but not the focus. The caption should focus on main subjects, so primary is one child.

Spatial relationships: The child is in front of the inflatable structure, moving towards it, then onto the slide.

Camera movement: The video seems to have a slight shake, maybe handheld. The camera angle is low, following the child's movement. The camera moves slightly to follow the child's action.

Background: Indoor gym with other people sitting in the back, but minimal description as per rules.

Now, chronological order:

- The child is initially near the purple mat at the base of the inflatable.
- The child walks towards the inflatable structure.
- The child climbs up the side of the inflatable.
- The child slides down the red slide.

Wait, let's check frames:

Frame 0: Child in blue is on purple mat (maybe sitting or lying? Wait, frame 0: [0.0 seconds] shows a child in blue on purple mat. Then frame 1: [1.4 seconds] the child is moving. Wait, the frames are short intervals.

Wait, the video starts with a child on the purple mat. Then the child stands up and moves towards the inflatable. Then climbs up the structure, then slides down.

So steps:

1. The child (wearing blue shorts, light top) is seated on a purple mat at the base of the inflatable slide.

2. The child stands and moves towards the inflatable structure.

3. The child climbs up the side of the inflatable.

4. The child slides down the red slide.

Camera: Handheld, slight shake, following the child's movement.

Now, put it in a concise paragraph.

Check rules: chronological order, motion and behavior, appearance (color, size, orientation), spatial relationships (in front of, etc.), camera perspective and movement.

Let's draft:

A child wearing a white shirt and blue shorts moves from a purple mat at the base of a colorful inflatable bouncy castle toward the structure. The child then climbs up the side of the inflatable, which features red, yellow, and green sections, and slides down the red slide. The camera follows the child's movement with a slight shake, capturing the indoor setting with minimal background details.

Wait, check if the child is on the mat initially. Frame 0: "a child in blue on purple mat". Wait, maybe "blue clothing"? Wait, the child is wearing blue, maybe shorts. Wait, the video: in the first frame, the child is in blue (maybe shorts), then the next frames show a child in white shirt and blue shorts (frame 1: [1.4 seconds] says "a child in white shirt and blue shorts is seen...").

Wait, need to be precise. Let's check the frame descriptions:

Frame 0: [0.0 seconds] – Child in blue on purple mat (maybe the first child is in blue, then the next child is different). Wait, maybe the main subject is one child.

Wait, the video is a sequence:

At the start, the inflatable structure is visible. A child in blue is on the purple mat. Then, a child in white shirt and blue shorts (maybe the same or different) is seen moving. Wait, the problem says "main subjects (people/animals/objects)". So the main action is the child moving toward the inflatable, climbing, sliding.

Wait, maybe the main subject is the child in white shirt and blue shorts. Let's see:

Discrete objects (children) exhibit locomotion on the inflatable structure, including sliding, climbing, and shifting positions on the slide and surrounding platforms.

The background (walls, ceiling lights, and distant structures) remains consistently static across frames with no uniform shifting or fluid motion (e.g., fire, smoke, water). No environmental elements dominate the scene.


A hand moves red, white, and gray poker chips across a dark surface, rearranging them. The camera shifts to reveal a person in a white shirt and brown vest with a bow tie standing behind a table, with playing card symbols visible in the background. The camera then pans to a wider view of the person at the table as they gesture with their hands.

Discrete objects: Hand (moving poker chips) and woman's hands (moving in front of PokerStars background).

Background (PokerStars logos and cards) is static. No fluid/environmental motion (fire, water, wind) detected.


A person in a white shirt and dark pants walks away from a large machine covered with a blue cloth, moving toward a doorway. Simultaneously, another person in a light blue shirt and dark pants stands to the right of the machine, observing. The camera remains relatively static with a slight shake, capturing the scene from a side angle.

Two distinct human subjects are moving: one individual approaches the machine, interacts with it, and shifts position; the second individual walks across the frame. Their motions are deliberate locomotion without fluid/environmental influence.

Background elements (walls, door, and floor) show no uniform shifting or environmental motion (fire, water, smoke, wind); static structure remains consistent throughout.


RAW CAPTION: Got it, let's tackle this. First, I need to describe the video in chronological order. The main subject is a person washing clothes by a river. Let's break down the frames.

In the first frame, the person is sitting on the ground near the river, wearing an orange shirt with a red apron, dark pants. There's a large metal basin, some clothes (yellow and green), and a red cloth. The background is a river with greenery.

Looking at the sequence: the person is handling the green/yellow cloth, moving it between the ground and the basin. The actions are washing—so the person dips the cloth into the basin, scrubs it, then maybe rinses or continues.

Need to mention appearance: person in orange top, red apron, dark pants. The cloth is bright green/yellow. Basin is metal, filled with water.

Spatial: The basin is in front of the person, the cloth is on the ground near the basin. The river is in the background.

Chronological order: The person starts by handling the cloth, then moves it to the basin, washes, then maybe repeats. Each frame shows progression of washing.

Background: river, some buildings, greenery. But keep minimal.

Camera: The video is a static shot? Wait, the frames show slight changes. The camera perspective seems consistent, maybe a fixed angle, no major movement.

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

- Subject (person) doing action (washing clothes), appearance, sequence of actions (dipping, scrubbing), objects involved (basin, cloth), background (river), camera.

Check rules: focus on motion and behavior chronologically.

So, "A person wearing an orange shirt and red apron sits on the ground by a riverbank, washing a bright green and yellow cloth. They dip the cloth into a large metal basin filled with soapy water, scrub it against the ground, and then lift it from the basin. The scene includes scattered laundry items and a red cloth nearby, with the river and greenery in the background. The camera remains stationary throughout the sequence."

Wait, check if it's concise. Let's make it shorter.

"A person in an orange shirt and red apron sits by a riverbank, washing a bright green cloth. They dip the cloth into a metal basin filled with soapy water, scrub it on the ground, and lift it from the basin. Nearby, a red cloth and other laundry items lie on the rocky shore. The camera maintains a fixed position, capturing the washing motion against the river backdrop."

Wait, need to make sure chronological: first dip, then scrub, then lift. The frames show progression from handling the cloth to dipping into basin.

Also, the person is wearing dark pants. Let's include that.

"A person dressed in an orange shirt, red apron, and dark pants sits on the riverbank, washing a bright green cloth. They dip the cloth into a large metal basin filled with soapy water, scrub it against the ground, and lift it out of the basin. A red cloth and other laundry items are scattered nearby on the rocky shore, with the river and greenery in the background. The camera remains stationary throughout."

Check if background descriptions are minimal. The river is essential for the setting, so it's okay. "Riverbank" is key.

Make it concise:

"A person wearing an orange shirt, red apron, and dark pants sits by a river, washing a bright green cloth. They dip the cloth into a metal basin filled with soapy water, scrub it on the ground, and lift it from the basin. Scattered laundry items and a red cloth lie nearby on the rocky shore. The camera stays fixed, capturing the washing action against the river backdrop."

Wait, the user said "chronological paragraph". Let's check each frame:

Frame 0: Person sitting, handling cloth.

Frame 1: Person moving cloth towards basin.

Frame 2: Person placing cloth on ground.

Frame 3: Person dipping cloth into basin.

Frame 4: Person scrubbing cloth (in basin).

Frame 5: Person lifting cloth out.

So chronological: handling cloth → moving to basin → dipping → scrubbing → lifting.

So the caption should reflect that sequence.

"A person in an orange shirt and red apron sits by a river, washing a bright green cloth. They move the cloth toward a metal basin filled with soapy water, dip it into the basin, scrub it against the ground, and lift it out. Nearby, a red cloth and other laundry items rest on the rocky shore. The camera remains stationary throughout the sequence."

Yes, that's chronological. Mention the main subject's actions step by step.

Check appearance: orange shirt, red apron, dark pants (since they're wearing dark pants as well).

Include pants: "A person in an orange shirt,

A person is actively washing clothes with their hands, moving the clothes and hands in discrete motions.

The river and distant shoreline are visible but show no significant fluid or environmental motion dominance; background elements remain relatively static with no uniform shifting.


Two individuals, one in a yellow shirt and blue shorts, the other in a green shirt and dark shorts, stand on an indoor badminton court. The person in green shifts position slightly toward the net, followed by the yellow-shirted individual moving toward the center court. The camera exhibits a slight shake during the sequence, maintaining a frontal perspective.

Two people (discrete solid objects in green/yellow shirts) moving due to locomotion; their motion appears intentional (e.g., interacting during a sport).

No shifting background elements detected; no fluid/environmental motion (fire, water, smoke, wind) present. Court lines and distant structures remain consistently static across frames.


A split-screen video shows two individuals: on the left, a person in a teal hoodie with white drawstrings moves indoors near a door, turning slightly while holding a phone; on the right, a person in a black jacket with long wavy hair walks away from the camera along a stone path outside a house with trees. The camera remains static, capturing both subjects in separate frames without significant movement.

Two humans: one sitting and gesturing (left side) and one walking (right side).

Both sides show static backgrounds (interior staircase and outdoor sidewalk with trees). No dominant fluid motion (fire, water, smoke) or wind is evident. Trees do not show significant sway.


Two girls sit on the floor, one in blue shorts with a red stripe and black top, the other on a pink cushion wearing a black top, both handling playing cards. The girl on the left shuffles and deals cards toward the center, while the girl on the right adjusts her cards. A colorful blanket lies in the background. The camera maintains a static top-down view.

Two children's hands are actively manipulating a deck of cards, moving them in discrete, deliberate motions (shuffling, picking up, placing down). The cards themselves move as solid objects due to physical contact with the children's hands.

The tiled floor and colorful box in the background remain static throughout the video. No fluids, smoke, or environmental motion (e.g., wind) are present.


A young boy with brown hair and a light gray shirt repeatedly picks up pieces of food from a glass bowl and transfers them into a metal container. An adult’s hand holds a plate with food in front of the boy. The boy moves his arm and body while handling the food, with the glass bowl positioned to the right of the metal container. The scene occurs in a room with wooden flooring and furniture in the background. The camera remains stationary at a slightly downward angle.

A child is moving their arms and head while eating, exhibiting discrete solid-object motion.

Background is stable with no shifting elements. No ambient environmental motion (fire, water, wind) detected.


A hand adjusts a blue bicycle frame, then manipulates a wooden ramp on a black metal cart with a wheel, followed by using a yellow and black tool to tighten a skateboard wheel, and finally adjusting a black spiky wheel with multiple bolts. Each action is shown in close-up shots focused on the hands and objects.

Hand moving bicycle stand, hands adjusting a small wheel attached to a bicycle, and hand holding a spiky sun-shaped object. All are discrete solid objects being manipulated by a person.

No shifting backgrounds or fluid/environmental motion (fire, water, wind). Background elements (grass, trees, pavement) are static.


RAW CAPTION: Got it, let's break this down. First, identify the main subjects. There are two people in the video: one in yellow and one in red. They're engaged in a martial arts or capoeira-like movement. The sequence starts with the yellow-clad person kicking the red-clad person. Then they move around, with the yellow person doing a sweep or kick, and the red person reacting. The background has a crowd watching, but we need to keep background minimal.

Chronological order: Start at 0.0s, yellow person kicks red, then they move, yellow does a high kick, red dodges, maybe some grappling. The crowd is around, clapping. Need to mention their colors, movements step by step.

Spatial relationships: Yellow is in front of red initially, then they switch positions. The crowd is surrounding them, seated.

Camera perspective: The video seems to be a medium shot, maybe handheld, with some slight movement to follow the action.

Check rules: focus on motion, appearance (colors), spatial (front, left, etc.), conclude with camera. Background minimal.

So, draft:

Two individuals engage in a martial arts exchange: a person in yellow attire executes a high kick toward a person in red, who dodges and counters with a low sweep. The yellow-clad figure then steps forward, moving to the left, while the red-clad individual responds with quick, evasive maneuvers. Both move dynamically within a circular space surrounded by an audience seated on the ground. The camera follows their movements with slight motion, capturing the sequence from a slightly elevated angle.

Wait, need to be more concise. Let's make it shorter.

First, the yellow person kicks red. Then they move, yellow does a kick, red counters. Then they continue, maybe a sweep.

At [0.0s], the yellow-clad participant kicks the red-clad individual, who bends backward. They then circle each other, with the yellow figure executing a high kick toward the red-clad participant, who dodges left. The red-clad individual then lunges forward, engaging in close-contact movement as the yellow figure steps back. The crowd remains seated in the background, observing. The camera follows the action with minimal movement, maintaining a medium shot perspective.

Check if all rules are met: motion chronological, appearance (yellow, red), spatial (dodges left, steps back), background minimal, camera movement.

Yes. Let's trim:

In a circular arena, a person in yellow executes a high kick toward a person in red, who dodges and bends backward. The yellow participant then steps forward, moving to the left, while the red-clad individual counters with a low sweep, lunging forward to engage. They continue their dynamic exchange within the ring, surrounded by seated onlookers. The camera tracks their movements with slight motion, maintaining a medium perspective.

Wait, maybe better to describe the sequence step by step.

At the start, the yellow-clad individual kicks the red-clad person, who bends backward. Next, the yellow figure moves to the left, executing a swift kick, while the red-clad individual dodges and lunges forward. They continue their fluid interaction, with the yellow person stepping back and the red-clad figure maintaining close contact. The audience sits around the perimeter, observing. The camera follows the action with minimal shake, capturing the exchange from a medium angle.

Check for conciseness and chronology. Maybe:

Two individuals, one in yellow and one in red attire, engage in a dynamic martial arts exchange. The yellow-clad participant initiates with a high kick toward the red-clad individual, who bends backward and dodges left. The yellow figure then steps forward, followed by a swift sweep as the red-clad person lunges forward. They continue their fluid interaction, moving in a circular pattern within the arena, surrounded by seated onlookers. The camera follows their movements with slight motion, capturing the sequence from a medium perspective.

Yes, that's concise. Let's make sure it's in chronological order: kick, dodge, step forward, sweep, lunges, continue.

Final check:

- Motion: yellow kicks, red bends/dodges, yellow steps forward, red lunges, etc.

- Appearances: yellow, red.

- Spatial: red dodges left, yellow steps forward.

- Background: seated onlookers (minimal).

- Camera: follows with slight motion, medium perspective.

Yes. Let's write the caption.

No shifting background or fluid/environmental motion detected. The background (bed, window, nightstand) remains static throughout the clip.


RAW CAPTION: Got it, let's break down the video. First, the scene: a man in a green shirt and khaki shorts is handling goats. There are four goats: a brown one, a black and white one, a black with white patches, and a white one. The man is moving with them, probably guiding or herding. The video starts with him standing, then he walks forward, and the goats follow. The background has a silo and some greenery, but we need to keep background minimal. The camera seems to follow the man and goats, maybe panning slightly. Let's check the rules: chronological order, motions, appearance, spatial relationships. So start with the man's position, his movement, goats moving around him. The goats are in various colors, moving in front of him. The camera is likely tracking the action, maybe a slight follow movement. Avoid background details unless essential. Let's structure it:

In the initial frame, a man in a green shirt and khaki shorts is positioned behind a group of four goats (brown, black-and-white, black with white patches, and white) in a grassy field. He then walks forward, guiding the goats as they move in various directions; the brown goat leads slightly, followed by the black-and-white goat, then the black with white patches, and the white goat stays close. The man maintains proximity to the goats, adjusting his position to control their movement. The camera follows the man and goats with a slight pan, capturing their motion from a ground-level perspective, with the silo visible in the background.

Wait, need to be concise. Let's check the rules: "concise, chronological paragraph". Let's start with the man's action, then the goats' motion. Let's list the steps:

1. Scene: man with goats in field.
2. Man moves forward, goats follow.
3. Describe goats' colors and positions.
4. Camera movement.

So: A man in a green shirt and khaki shorts herds four goats—brown, black-and-white, black with white patches, and white—across a grassy field. Initially positioned behind the goats, he walks forward, guiding them as they move in front of him; the brown goat leads, followed by the black-and-white goat, then the black with white patches, and the white goat trails. The camera follows their movement with a slight pan, maintaining a ground-level perspective as the man adjusts his position to control the goats' direction.

Check rules: a) motion and behavior in order. b) appearance and number. c) spatial relationships (brown leads, etc.). d) camera perspective (ground-level, slight pan). e) background minimal (silo is in background but maybe not essential? Wait, the problem says "minimal unless essential for understanding motion". The silo is part of the background, but maybe we can skip it. Let's see: the main motion is man and goats, so background can be mentioned only if needed. Since the video is in a field with silo, but maybe not necessary for motion. Let's see the original video: the background has a silo, but the action is in the foreground. So maybe just say "grassy field" without the silo. Wait, the first frame mentions the silo, but according to rule e, minimal background unless essential. So maybe the silo isn't essential, so we can omit it. Let's revise:

A man in a green shirt and khaki shorts herds four goats—brown, black-and-white, black with white patches, and white—across a grassy field. He starts behind the goats, then walks forward, guiding them as they move in front of him; the brown goat leads, followed by the black-and-white goat, then the black with white patches, and the white goat stays close. The camera follows the group with a slight pan, maintaining a ground-level perspective as the man adjusts his position to direct the goats' movement.

Wait, check if the goats' order is correct. Let's look at the frames:

Frame 0: goats are in front of the man, he's behind. Frame 1: man moves forward, goats move. Frame 2: man is in front of some goats. Wait, in frame 0: man is standing, goats are in front of him (he's behind them). Then frame 1: he walks forward, goats move. So the man was behind, then moves to be with them. The goats' order: in frame 0, the goats are from left to right: black with white patches (left), brown (middle), black and white (right), white (front? Wait, no. Wait, frame 0: the man is on the right, goats are in front. Let's count: leftmost is black with white patches (has white patches), then brown

A person in a green shirt and three goats are moving; the person walks toward and interacts with the goats, while the goats shift positions and move across the frame.

Static background elements (silo, grass, distant trees) show no uniform shifting or fluid motion; no fire, water, or wind-driven phenomena dominate the scene.


A person in a blue and black jacket holds a yellow and black cleaning tool, bends downward, and inserts the tool into a rusty metal drain grate. The camera transitions to a close-up of the tool entering the grate’s slots, then shifts to show the tool navigating inside the drain to clear debris. The sequence alternates between medium and close-up shots, emphasizing the tool’s movement from the grate into the drain’s interior.

A person (solid object) bends down and manipulates a tool. The tool moves toward and into a metal drain grate, indicating discrete object motion due to physical interaction.

Static background elements (wooden crates, concrete ground) show no uniform shifting. No fluid/environmental motion (e.g., fire, flowing water, smoke) dominates the scene. The drain inspection involves tool interaction but no ambient environmental motion.


RAW CAPTION: Got it, let's tackle this. First, I need to describe the video chronologically. Let's look at each frame.

Frame 0: A person in a dark shirt and jeans is on a skateboard, crouching. Another person in a dark shirt and shorts is standing nearby. The ground has yellow lines.

Frame 1: The skateboarder is in mid-air, jumping. The other person is still standing.

Frame 2: The skateboarder lands on the skateboard, maybe doing a trick. The other person is still there, watching.

Frame 3: The skateboarder is moving forward, balancing. The other person is to the left, maybe also on a skateboard?

Frame 4: The skateboarder is still moving, maybe preparing for another trick. The other person is in the background.

Frame 5: The skateboarder does a trick where they jump, and the skateboard flips. The person in the background is there.

Wait, the video is 5 seconds, each frame is a moment. Let's structure the chronology.

First, the main subject: a person (dark shirt, jeans) on a skateboard. Initially crouching (frame 0). Then jumps off (frame 1), lands (frame 2), rides forward (frame 3), then does a trick where the board flips (frame 4-5). Another person (dark shirt, shorts) is present, sometimes standing, sometimes on skateboard? Wait in frame 2, the other person is in the background. In frame 5, the main subject is jumping, skateboard flipping.

Need to describe motion step by step. Also, the other person's presence: at start, standing; then maybe riding?

Let me parse each frame:

[0.0s]: Person (dark shirt, jeans) on skateboard, crouching. Another person (dark shirt, shorts) stands to the left. Yellow lines on ground.

[0.3s]: Main person in mid-air, skateboard under them, body bent. Other person still standing.

[1.0s]: Main person lands on skateboard, standing. Other person is to the left, slightly crouched.

[1.6s]: Main person rides forward, hands extended. Other person is behind, maybe on skateboard.

[2.2s]: Main person jumps, skateboard flips beneath them. Other person is in background.

Wait, the frames are 0 to 5, each showing a moment. Let's list the key actions:

- Starts crouching on skateboard.

- Jumps into the air, performing a trick.

- Lands, continues riding.

- Moves forward, hands out for balance.

- Then jumps again, skateboard flips.

Also, the other individual: in the first frame, standing; in later frames, possibly riding or watching.

Now, concise chronological description.

Main subject: male skateboarder (dark shirt, dark pants). Another male (dark shirt, shorts) is present.

Sequence: Skateboarder starts crouched on board. Lifts off, airborne. Lands, continues riding. Moves forward with arms extended. Performs a jump trick where the skateboard flips beneath him.

Other person: Initially standing to the left, then appears to ride skateboard in background.

Camera perspective: Likely a fixed camera, slight movement as the skateboarder moves.

Background: Park-like area with yellow lines, grass, structures.

But need to keep background minimal. So focus on motion.

Let's structure the caption:

At the beginning, a male skateboarder in a dark shirt and jeans crouches on his board. He then jumps into the air, landing on the board while riding forward. Continuing, he extends his arms for balance as he moves across the yellow-lined pavement. Another person in a dark shirt and shorts stands nearby, then appears to ride a skateboard in the background. The skateboarder performs a trick, launching himself and flipping the board beneath him. The camera remains mostly static, capturing the sequence from a slightly low angle.

Wait, but need to be concise. Let's check the rules: chronological, focus on motion, appearance (color, size), spatial relationships (in front, left, etc.), conclusion with camera.

Let me draft:

A male in a dark shirt and jeans crouches on a skateboard. He jumps upward, lands on the board, then rides forward with arms extended. To his left, another male in a dark shirt and shorts stands and later rides a skateboard. The first male performs a trick, launching into the air and flipping his skateboard. The camera maintains a fixed position, capturing the action from a ground-level perspective.

Wait, need to check if "to his left" is correct. In frame 0, the other person is to the left of the skateboarder. Then as the skateboarder moves, the other person is behind?

Maybe: Initially, the skateboarder (dark shirt, jeans) crouches on his board

Two skateboarders perform distinct physical maneuvers (jumps, tricks) involving solid objects (skateboards, bodies) under explicit physical forces (gravity, propulsion).

Background elements (parking lot lines, pillars, trees) show no uniform shifting or fluid motion; no fire, water, smoke, or significant wind effects detected.


A person in a gray shirt seated at a white table manipulates a small red object, then shifts it and picks up a pink item from the table, while another person in a dark jacket remains seated across the table with hands resting. The scene occurs in a well-lit indoor space with a large window showing a snowy exterior; the camera maintains a fixed position throughout.

Two people interacting: left person writes on notepad, flips pages, moves small object (pen/marker) toward right person; discrete solid objects (people, notepad, pen) exhibit explicit locomotion/physical interactions.

No shifting backgrounds; static walls and window view with no fluid/environmental motion (fire, water, smoke, wind) detected.


RAW CAPTION: Got it, let's break this down. First, the video starts with a person in a teal shirt and khaki pants working with an anvil. The anvil is rusty, shaped like a traditional blacksmith's anvil. The person is holding a piece of metal, maybe a nail or a small bar, and using a hammer to strike it. In the background, there's a yellow box and some equipment. Then, the person adjusts the metal piece on the anvil, using tongs or a tool to hold it in place. The action is a bit of hammering, then moving the metal around. Wait, the next part—the video transitions to a different scene? Wait, no, the description says "You are an expert video captioner. Your task is to generate a concise, chronological paragraph describing the provided video." The provided video is the frames given. Let's check the frames:

Frame 0: Person's hand near a yellow box and an anvil.

Frame 1: Person's hand moving towards the anvil, placing something (metal) on it.

Frame 2: Person is holding a hammer and the metal on the anvil.

Frame 3: Person is striking the metal with the hammer.

Frame 4: Person is adjusting the metal with a tool.

Frame 5: The scene changes to a large group of people on horses, but wait—wait, the user provided the video frames. Wait, no, the video is a sequence. Wait, the user's input is a series of frames. Let's read the video description again. The user says "provided video" and lists the frames. Let's see:

[0.0] shows a person in teal shirt, hand near yellow box, anvil.

[1.4] person places metal on anvil.

[2.5] person uses hammer to strike.

[3.6] person continues hammering, with orange and green crates in background.

[4.7] the scene shifts to a large group of people on horses, but wait, that's the next frame. Wait, but the problem says "the provided video" which is these frames. Wait, no, maybe the video is a sequence where first it's the blacksmith, then a horse scene. Wait, but the rules say to describe the video chronologically. Let's check the frames:

The first part: the person is working with an anvil (blacksmithing). Then, the last frame is a scene with many people on horses. Wait, but that's a transition. But the task is to describe the video in chronological order.

Wait, the user's input has 5 frames. Let's parse each:

Frame 0: A person in a teal shirt and khaki pants is seen holding a hammer near a rusted anvil with a yellow box in the background.

Frame 1: The person places a metal object onto the anvil.

Frame 2: The person uses the hammer to strike the metal.

Frame 3: The person continues hammering, with green and orange crates visible in the background.

Frame 4: The scene shifts to a large group of people riding horses.

Wait, but the task says "chronological paragraph". So the video starts with the blacksmithing, then cuts to the horse scene. But the rules say: focus on motion and behavior in chronological order. So first part: person working with anvil, then the scene changes.

But let's check the rules again: a) Focus primarily on the motion and behavior of main subjects in chronological order.

So first, the main subject is the person (teal shirt, khaki pants) working with the anvil. They move the metal, strike it, then the scene changes to people on horses. Wait, but maybe the horse scene is a different part. Let's structure it:

First, the person is in teal shirt, hands working on the anvil. They pick up a metal piece, place it on the anvil, then hammer it. Then, the scene shifts to a group of people on horses.

But the user's input for the video: let's see the frames:

[0.0] shows a person in teal shirt (only hands visible) near yellow box and anvil.

[1.4] person places metal on anvil.

[2.5] person uses hammer to strike metal.

[3.6] person is hammering, with orange and green crates.

[4.7] scene changes to many people on horses.

Wait, but in the problem statement, the user wrote:

"the provided video" with the frames. So the video sequence is: first the blacksmithing, then a shot of people on horses.

But the caption needs to be chronological. So start with the person working with the anvil, then the scene changes.

Now, the rules: b) Briefly describe appearance

The person’s hands and tools (pliers, hammer) move as they manipulate the metal on the anvil, exhibiting explicit physical interactions like hammering and positioning.

The background elements (crates, wall, and floor) show no uniform shifting or fluid motion; no fire, water, or smoke is present.

The man in black gestures with his hands and adjusts his shirt, while the woman gestures toward the man in blue. Pedestrians move through the city street backdrop as the camera maintains a steady perspective with minimal movement, capturing the interaction from a frontal angle. </think>  <caption_output>A man in a black shirt and light pants converses with a man in a light blue shirt; a woman in a brown shirt approaches them, engaging in dialogue. The man in black gestures with his hands and adjusts his shirt, while the woman gestures toward the man in blue. Pedestrians move through the city street backdrop as the camera maintains a steady perspective with minimal movement, capturing the interaction from a frontal angle.

Discrete solid objects (people) are moving: individuals walking past the scene, conversing, and adjusting positions.

Static background elements (buildings, street signs) show no uniform shifting; no fire, water, smoke, or wind effects observed.


Several individuals in black, red/white, and blue athletic wear actively throw and chase yellow balls across an indoor gym court with yellow cones. They move dynamically around the cones, engaging in rapid motion as they interact with each other and the balls. The camera pans left, following their actions with slight shake, capturing the energetic interactions.

Solid objects (people, yellow balls) are moving due to physical interactions (throwing, catching, running), with clear bounding boxes for tracking.

Background elements (blue walls, court markings) show no uniform shifting, and there are no fluid or gaseous motions (fire, water, smoke) present.


RAW CAPTION: Got it, let's break this down. The video shows a person in a room. First, I need to note the main subject: a person wearing a white shirt and dark pants, moving. Let's check the chronological order. The person starts standing, then moves—maybe dancing or walking? Let's see the frames. The person is initially in the middle, then steps forward, moves their arms. The room has a guitar, bookshelf, lamp. But background minimal unless essential. So focus on the person's motion.

Chronological: starts standing, then takes steps, moves across the room. Appearances: white shirt, dark pants, white shoes (since they're visible). Number: one person. Spatial: room with wooden floor, bookshelf to the right (since in the first frame, bookshelf is on the right side). Wait, in the video, the person is in front of the bookshelf initially? Let's check the frames. Frame 0: person is near bookshelf and guitar. Then moves left? Wait, the video shows the person moving towards the camera, then maybe stepping. Wait, the movement: in the first frame, person is standing, then in next frames, they're moving forward (towards the camera), taking steps. So their motion is walking forward across the room.

Camera perspective: the video seems to have a slight shake, maybe handheld. No pan, just the person moving. Background: minimal, just room elements like bookshelf, guitar, but keep that minimal. So description: person in white shirt and dark pants walks forward across the room, moving from near the bookshelf towards the camera. Camera is stationary with slight shake, medium shot. Wait, need to follow rules.

Check rules: a) motion chronologically. So start position: standing near bookshelf (right side, maybe), then moves left? Wait, in frame 0: person is on the right side (bookshelf on right), then frame 1-4: person is moving towards the left? Wait, no, the frames show the person stepping forward. Wait, let's count: frame 0 to 5. Person starts at position where bookshelf is to the right, then moves to the left side of the frame? Or towards the camera. Wait, in the video, the person's movement is forward (towards the camera), so their position shifts from back to front. So chronology: person stands, then takes steps forward, arms moving slightly. Appearance: white shirt, dark jeans, white shoes (as seen in frame 0, shoes are white). Number: one person.

Spatial relationships: the person is initially in the middle-right of the frame (with bookshelf to the right), then moves towards the center-left as they walk forward. But maybe just say "moves forward across the room."

Background: minimal, room has bookshelf, guitar, lamp, but only mention if essential. Since the motion is in the room, maybe not essential. So focus on person's action.

Camera perspective: static camera with slight shake (since the video is shaky).

Putting it all together:

A person wearing a white shirt and dark pants walks forward across a wooden-floored room, moving from near the bookshelf toward the camera; their arms move slightly as they step. The camera remains stationary with a slight shake, capturing the person's motion from a medium distance.

Wait, check rules. Background descriptions minimal. So maybe don't mention bookshelf explicitly, just "room with wooden floor." Wait, the rules say "keep background descriptions minimal unless essential for understanding motion." So if the motion is in the room, maybe the background is just part of the room, but the key is the person's movement. Let's rephrase.

Person in white shirt and dark jeans walks forward through a room with wooden flooring, their body shifting position as they step; the camera remains fixed with a slight shake.

Wait, but need to mention spatial relationships if relevant. So maybe "walks forward from the right side of the frame toward the center."

Wait, in the first frame, the person is on the right side (bookshelf to their right), then they move left across the room. So the motion is from right to left in the frame.

Let me check the frames again. The first frame shows the person standing with the bookshelf to their right (since bookshelf is on the right side of the image). Then in subsequent frames, the person moves left (toward the left side of the frame), so their position shifts leftward as they walk.

So chronology: person stands near bookshelf on right, then steps left across the room, arms moving.

Appearance: white shirt, dark pants (jeans), white shoes.

Number: one person.

Spatial: starts right side, moves left.

Camera: static with slight shake.

So putting it all together:

A person in a white

A person (boy) is moving: raising arms, stepping forward/backward, and walking within the room; all movements are discrete and attributable to human locomotion and arm gestures.

The background (guitar, bookshelf, lamp, window) is static with no shifting or fluid motion (e.g., fire, water, wind); walls and floor remain uniformly fixed throughout.


A man in a white tank top and dark shorts swings an axe with an orange handle to split a log on the ground, bends forward to adjust the wood, and continues chopping; stacked logs and a wooden fence are visible in the background, with the camera maintaining a slight shake while following his movements.

A person (wearing a white tank top and dark shorts) is swinging an axe to chop wood. The person's motion includes lifting the axe, bringing it down, and adjusting posture while interacting with the logs and ground.

The wooden fence and ground elements are static with no uniform shifting, indicating no significant ambient environmental motion (e.g., no fire, water, or wind-driven motion observed).


In the video, three individuals are positioned on a dimly lit stage. A woman in a black dress with a red shawl stands on the left, a man in a black suit and white pants is centered, and a woman in a blue-pink striped dress holding a bag stands on the right. The man steps forward and shifts his position toward the right, while the others make minor adjustments. The camera maintains a fixed frontal perspective throughout.

Three people (actors) are moving: stepping and turning in place, indicating locomotion. The motion is discrete and solid.

The background (stage set including wall and table) is static with no shifting. No fire, water, smoke, or wind observed. Lighting changes are due to stage lighting, not environmental motion.


A person wearing a white shirt and light shorts walks toward the camera; the camera then shifts downward to show their bare feet stepping on a wooden herringbone-patterned floor, with a few shoes scattered nearby as they continue moving. The camera maintains a slight downward pan from chest to feet.

A person (human) is moving through space, performing leg and body motions (e.g., stepping, bending) indicative of locomotion or exercise. No other discrete objects show motion.

The background (wooden door, herringbone floor, wall) is static with no shifting or fluid motion. No fire, water, smoke, or wind is present, so ambient environmental motion is absent.


A guitarist in camouflage shorts, white helmet, and bare feet strums while shifting position on stage, accompanied by a bassist in dark shirt to his left and a drummer behind him; audience members in front move and gesture as the band plays, with the camera panning right and exhibiting slight shake.

Discrete solid objects (band members: singer, guitarist, drummer; audience members) move due to locomotion (singer stepping, guitarist gesturing, audience entering/leaving frame).

No shifting backgrounds or fluid/environmental motion (fire, water, wind) detected; stage setup remains static with no dominant ambient elements.


A person wearing a blue cap, gray sleeveless top, blue jeans, and white sneakers stands on a tile floor near a stone fireplace, then steps off a board, turns, and walks toward the fireplace, passing boxes and tools on the floor. The camera remains stationary.

A person (solid, distinct object) is moving: walking, bending, and handling tools in the foreground.

No significant shifting of background elements (walls, floor, fireplace) observed; no fire, water, smoke, or wind motion present.


A man in a dark gray shirt and cap adjusts a milking apparatus attached to a light tan cow’s udder while moving around the cow’s hindquarters in a stall. The cow remains stationary as the man secures the equipment with his hands. The camera follows his motion, panning slightly to track his position.

A person (discrete solid object) moves around a stationary cow, performing milking actions. The person's motion is driven by locomotion and manual manipulation.

Static background elements (walls, milking apparatus) show no uniform shifting; no fluid/environmental motion (fire, water, smoke, wind) is present.


RAW CAPTION: Got it, let's break this down. The video starts with a hockey game scene. First frame: players in black and orange jerseys (one with #2) near the net. Then it shifts to two black jerseys (55 and 86) on the ice. Then a white jersey (88) with black stripes. Then a player in white (22) and black. Wait, need to track chronologically.

Main subjects: hockey players. First, players in black and orange (maybe two?) near net. Then two black jerseys (55 and 86) moving on ice. Then white jersey (88) with black stripes. Then white jersey (22) with black. So chronological: starts with net action, then players skating, passing puck.

Appearance: jerseys in black/orange, white/stripes. Numbers like 2, 55, 86, 88, 22. Spatial: players in front of net, then moving across ice. Camera: probably static or slight pan? Wait, the video is a sequence, so camera perspective might be following the action.

Background: hockey rink, net, ice. Minimal, as per rule e.

Rules: focus on motion, chronological. So sequence: first, a hockey player in an orange helmet and black jersey (maybe #2) near the net, interacting with a player in black and orange. Then two players in black jerseys (55 and 86) skate, pass puck. Then a white jersey (88) with black stripes chases. Then a white jersey (22) with black stripes plays.

Wait, need to check each frame. First frame: players in black (one with #2) and orange (maybe goalie), near net. Then next frame: two black jerseys (55 and 86) on ice, puck in play. Then white jersey (88) with black stripes, then white jersey (22).

So chronological: the scene opens with hockey players in black and orange jerseys near the goal net, then shifts to two black-jerseyed players (numbers 55 and 86) skating and passing a puck across the ice, followed by a white-jerseyed player (number 88) with black stripes attempting to intercept, and finally a white-jerseyed player (number 22) with black stripes involved in the play.

Camera perspective: likely a standard hockey broadcast angle, following the action. No specific camera movement mentioned, so maybe static or smooth tracking.

Need to keep it concise. Let's structure:

The video begins with hockey players in black and orange jerseys near the goal net, then transitions to two players in black jerseys (numbers 55 and 86) skating and passing a puck, followed by a white-jerseyed player (number 88) with black stripes pursuing the play, and finally another white-jerseyed player (number 22) with black stripes participating. The camera maintains a fixed broadcast perspective, tracking the action across the ice rink.

Wait, check rules: exclude text recognition. So don't mention "numbers" but maybe "jerseys with visible numbers". Wait, rule f: exclude named characters or stylistic analysis. So can't mention numbers? Wait, the problem says "briefly describe their appearance and number (color, size, orientation)"—wait, rule b says "mention number (color, size, orientation)". Wait, the instruction says: "b) Briefly describe their appearance and number (color, size, orientation)". So need to include number? Wait, but in the frames, the numbers are visible (like 2, 55, 86, 88, 22). But rule f says "Exclude text recognition". Oh, conflict. Wait, the problem says: "Exclude text recognition, named characters, or stylistic analysis." So numbers are text recognition? So don't mention numbers. Oh, that's important. So can't say numbers 55, 86. So describe as "players in black jerseys" without numbers.

Wait, the user's rules: "f) Exclude text recognition, named characters, or stylistic analysis." Text recognition includes numbers. So we shouldn't mention the numbers. So focus on colors: black, white, orange (for jerseys), and their actions.

So revised: The video opens with hockey players in black and orange jerseys near the goal net, then shifts to two players in black jerseys skating and passing a puck across the ice. Subsequently, a player in a white jersey with black stripes enters the play, followed by another player in a white jersey with black stripes. The camera maintains a fixed broadcast angle, tracking the players' movements on the ice rink.

Check rule a: chronological motion.

Discrete solid objects include hockey players (in full gear) and the puck. Players are skating, passing, and colliding with the puck, exhibiting clear locomotion and collision physics.

The background (ice rink boards, goal net, and static elements) shows no uniform shifting or fluid motion; no fire, water, or wind-driven elements are present.


In a dimly lit room with a red curtain backdrop, a large group of people move rhythmically, some shifting positions and walking toward the camera while others remain in place. The camera, positioned at a slightly shaky angle, pans left throughout the sequence, capturing the ongoing motion of the crowd.

The primary discrete objects are groups of people moving rhythmically in a dance-like pattern; their motion is locomotion (stepping, turning) and appears coordinated.

The background (red wall, lighting) remains static with no shifting or environmental effects (fire, water, wind).


A girl with long blonde hair, wearing a gray sweater and black pants, stands on a step stool near a door, holding a camera up to her face. A boy in a gray shirt and dark pants walks into the frame, approaches a gray box on the floor, and bends down to interact with it. The camera remains static throughout, capturing the scene from a fixed perspective in a hallway with minimal background details.

Two people: one on the ground moving by walking/stepping, and one on a rod adjusting position while holding a camera. Both movements are solid and distinct.

Background elements (walls, door) are static; no fluid or environmental motion (fire, water, smoke, wind) observed.


An older bald man wearing a light-colored shirt and dark pants stands near a stream, holding a fishing rod. He casts the line into the water, adjusting his stance as the rod moves. The camera follows him from behind, slightly shaky, capturing his back and the surrounding greenery with minimal background detail.

A single person (discrete solid object) is visible, performing fishing-related actions (adjusting posture, rod movement), exhibiting deliberate locomotion due to physical interaction with the environment.

Background features (trees, water) show subtle swaying, indicating environmental motion (wind-driven foliage and water flow), consistent with ambient environmental elements. No uniform background shift suggests camera stability.


A hand extends into dark, murky water, interacting with two elongated greenish fish swimming near the surface. The hand moves slightly, adjusting position as the fish glide around it; one fish swims to the left while the other remains more stationary. The hand then pulls a small object from the water, causing a brief splash. The camera maintains a close-up, slightly shaky perspective focused on the hand and immediate water surface, with minimal background detail.

A hand releases a fish, which then swims away through the medium (likely water). The fish exhibits discrete, solid-object motion due to its locomotion (swimming), while the hand's movement is part of the action but not the primary motion source.

The background consists of a dark, static surface with greenish elements that show no uniform shifting across frames. There is no dominant fluid or environmental motion (e.g., water flow, wind) that dominates the scene beyond the object movement.


A man in dark clothing and a red hat stands on a raised platform, holding a red cloth, while a child in red stands beside him. The man gestures with the cloth as they shift positions slightly, with a musician in traditional attire playing an instrument behind them. The camera remains steady, capturing the stage and audience from a frontal perspective with minimal background details.

Performers on stage are moving (dancing, gesturing) and audience members show minimal movement.

Background trees and stage structure are stable; no fire, water, smoke, or significant wind-induced motion observed.


RAW CAPTION: Got it, let's break this down. The task is to create a concise chronological paragraph about the video. First, identify the main subjects. There are dancers, probably belly dancers, since the attire is revealing with belts and long skirts. Let's look at the sequence.

Frame 0: A woman in a black crop top, black pants with a belt, and long sleeves (black) is dancing. She's holding a microphone? Wait, no, maybe a stick? Wait, the description says "black crop top, black pants with a belt." She's moving, arm raised.

Frame 1: She's moving, maybe turning. The camera shifts.

Frame 2: Another dancer comes into view? Wait, the video shows multiple dancers. The first dancer is moving across the space.

Frame 3: More dancers joining. The background has tripods and musical instruments, but we need minimal background.

Frame 4: More dancers, moving in formation.

Frame 5: The camera follows the dancers, moving as they dance.

Now, chronological order: Start with the first dancer, then others joining. Describe their appearance: black attire, crop top, pants with belts, long skirts? Wait, the video shows a woman in a black crop top and long black skirt (since it's a belly dance style, but the description says pants with a belt—maybe a long skirt or pants? Wait, the image shows a belt with decorations, so probably a long skirt. Let's check.

Appearance: women in black crop tops, black long skirts, belts with accessories. Number: at least two, then more.

Motion: The first dancer starts, then another enters, they move across the floor. The camera follows them, panning to show the group.

Spatial: The dancers are in a room with musical equipment (tripods, maybe a drum set) but minimal background.

Camera movement: The camera moves with the dancers, maybe panning left or following their movement. The description says "pan left" in the rules, but we need to see. The video shows the camera following the dancers, so probably a smooth pan.

Now, structure the caption:

First, introduce the main subjects: multiple women in black crop tops and long skirts with decorative belts.

Chronology: One dancer begins, then others join, moving across the room in formation.

Appearance: All wearing black, crop tops, long skirts (or pants with belts), decorative belts.

Spatial: They are in a room with musical equipment, but focus on their movement.

Camera: The camera follows the dancers, panning to capture their movements.

Check rules: avoid text, names, styles.

Putting it all together:

In a dance studio, multiple women in black crop tops, long skirts, and decorative belts begin moving rhythmically. The first dancer starts in the foreground, then others join, moving across the room in formation. They perform coordinated motions, turning and shifting positions, while the camera pans to follow their movement and capture the group dynamic.

Wait, check if it's chronological. First dancer, then others join. Mention number: at least three (the video shows multiple). Appearance: black outfits, crop tops, long skirts, belts. Motion: dancing, turning, shifting.

Camera: The camera pans to follow the dancers.

Background: minimal, just the studio with musical equipment, but we can skip unless essential. The problem says "keep background descriptions minimal unless essential for understanding motion." So maybe not necessary, but since it's a dance studio, maybe just mention "dance studio" briefly.

Let me check the example. The user says "focus on motion and behavior of main subjects in chronological order."

So:

A woman in a black crop top, long black skirt, and decorative belt dances in a dance studio. As she moves, more women in similar black attire join her, forming a group that turns and shifts across the room. The camera follows the dancers, panning to capture their coordinated movements.

Wait, need to be concise.

Final draft:

In a dance studio, a woman in a black crop top and long black skirt with decorative belt begins dancing, then multiple women in similar black attire join her, moving rhythmically across the room. They turn and shift positions while the camera pans to follow their synchronized motions.

Check the rules:

a) Motion and behavior chronological: yes, first woman starts, then others join, move.

b) Appearance and number: black crop tops, long skirts, decorative belts; multiple women (at least 3).

c) Spatial: moving across the room.

d) Camera: pans to follow.

e) Background minimal: "dance studio" is enough, maybe.

f) No text, names, etc.

Yes, this should work.

<caption_output>In a dance studio, a woman in a black crop top, long black skirt, and decorative belt begins dancing, then multiple women in similar black attire join her, moving

Multiple dancers in black attire perform coordinated belly dance movements. Solid objects (dancers) exhibit distinct motion: arm swings, torso isolations, and skirt rotations driven by muscular locomotion. Bounding boxes track individual dancers clearly.

Background elements (walls, bench, tripod) show no significant shifting or fluid motion. No fire, water, smoke, or wind present. Background remains static throughout the clip.


A hand wearing a striped sleeve holds a small metallic object over a white surface with concentric circles and water droplets. The hand rotates the object in a circular motion across the surface, adjusting its position. The object is gripped between the thumb and fingers. The camera maintains a close-up, static view of the hand and surface.

A hand manipulates a small object on the platform, while a white cylindrical object is tilted to dispense granular material (e.g., sand) onto the platform. Both objects exhibit distinct, controlled physical movement.

Static circular platform with marked concentric circles serves as background; no uniform shifting or fluid motion observed (no fire, water, smoke, or wind).


RAW CAPTION: Got it, let's break this down. The video starts with two people at a table. One is in a red robe, writing, the other in a dark jacket and cap, raising a glass. Then the cap guy moves the glass down. Next, the scene shifts to a table with wine bottles labeled 18, 19, 20, 21, 22. A hand adjusts bottle 19. Then a close-up of bottles 16, 17, 18.

Need to capture chronological order. First, two people at table: one in red robe (sitting, writing), other in dark jacket/cap (holding glass, then moves it down). Then cut to table with wine bottles, hand moving bottle 19. Then close-up of bottles 16-18.

Check rules: motion and behavior, chronological. Mention appearance (red robe, dark jacket, cap, bottle labels). Spatial: cap guy to right of red robe. Then table with bottles, hand adjusting. Camera moves from table scene to bottles, then close-up.

Background minimal, exclude text recognition (but labels are numbers, so maybe mention labels as numbers). Wait, rule f says exclude text recognition, but maybe the numbers are part of the object description. Wait, the user says "Exclude text recognition, named characters, or stylistic analysis." So maybe don't mention the numbers on bottles? Wait, but the numbers are part of the bottle labels, but since they're numbers, maybe it's part of the object description. Wait, the instruction says "Exclude text recognition" so maybe skip the numbers. Hmm.

Wait, the example: in the video, bottles have numbers 18, 19, etc. But rule f says "Exclude text recognition, named characters, or stylistic analysis." So text like 18 is text recognition, so don't mention the numbers. Oh, right. So instead of "bottles labeled 18, 19", just say "bottles with numbers".

Wait, but the user's example in the video has numbers, but the rule says exclude text recognition. So in the caption, don't mention the numbers. So just say "bottles" without the numbers. Wait, but the numbers are part of the object's identification. Hmm.

Wait, the rules: "Exclude text recognition, named characters, or stylistic analysis." So text recognition would be reading the numbers, so we can't mention the numbers. So in the caption, describe the bottles as "black wine bottles" without the numbers.

Let me check the initial frames:

Frame 0: two people at table. Person in red robe, person in dark jacket/cap.

Frame 1: same, cap guy moves glass down.

Frame 2: cap guy moves glass down, red robe person still writing.

Frame 3: cut to table with wine bottles.

Frame 4: hand adjusting bottle.

Frame 5: close-up of bottles.

So sequence:

- Two people seated at a table; one in red robe is writing, the other in dark jacket and black cap raises a glass then lowers it. The camera shifts to a table with multiple dark wine bottles arranged in a row. A hand adjusts one bottle. The camera then focuses on a close-up of three bottles in the arrangement.

Now, check appearance: red robe (color), dark jacket (color), black cap (color). The hand is part of a person (but we don't know who), so just "a hand".

Spatial: cap guy is to the right of the red robe person. The bottles are on a table, arranged in a row.

Camera perspective: starts at eye-level, then shifts to top-down? Wait, the transition from the people to the bottles: the first scene is a medium shot of the table with people, then cuts to a close-up of the bottles.

So camera movement: initial shots are at table level, then cuts to a close-up of the bottles.

Now, put it all together in chronological order, concise.

First part: Two individuals sit at a table; one wears a red robe and writes, the other in a dark jacket and black cap raises a glass before lowering it. The camera shifts to a table with several dark wine bottles arranged in a row. A hand adjusts one bottle, then the camera focuses on a close-up of three bottles.

Check rules: motion (raising glass, writing, adjusting bottle), chronological (starts with people, then bottles). Appearance: red robe, dark jacket, black cap, dark wine bottles. Spatial: cap guy to right of red robe, bottles arranged in row. Camera perspective: initial medium shot, then close-up.

Exclude text recognition: so don't mention the numbers on the bottles. The user's rule says "Exclude text recognition", so numbers like 18

In the first scene, a man drinking and a woman sitting, and a third person entering. In the second scene, a hand moving wine bottles.

The background (wall, door, poster) remains static throughout. No fire, water, smoke, or wind is present. Therefore, no ambient environmental motion.


RAW CAPTION: Got it, let's break this down. The video shows two people changing a tire on a black car. First, the main subject is the car: a black Tesla Model 3 (but we can't mention the model, so just black car). Then two people: one in black shirt and jeans, another in black shirt and jeans (wait, maybe different? Let's check the frames). In the first frame, one is kneeling, the other standing. Then they move: the standing person helps the kneeling one. Let's see the sequence.

First, the person kneeling (maybe with gloves) is working on the wheel. The standing person moves around, then kneels down too. They're both near the rear wheel. The background has a house and some greenery, but minimal. The camera is probably stationary, no movement. Let's structure chronologically.

1. Two individuals are at the rear of a black car. One person (wearing a black shirt and jeans, with gloves) is kneeling and working on the wheel. The other person (also in black shirt and jeans) stands nearby.
2. The standing person moves closer, then kneels beside the first person to assist with the tire change.
3. The person in blue jeans (wait, the video shows them with gloves, maybe different clothing? Wait, the first person is kneeling, the other is standing. Then the standing one steps back, then moves to help. The tire is being removed or replaced. The spare tire is visible on a cart.

Wait, need to check the actions: the first frame, the person kneeling is working, then the other person helps, then the kneeling person is on the ground, the other stands. Then the standing person walks away, the kneeling person continues working. Wait, the timestamps: [0.0] shows one kneeling, one standing. [1.4] the standing person moves to help, then [2.5] the standing person is standing next to the kneeling one, then [4.5] the standing person moves away. Wait, maybe the sequence is: two people, one kneels, the other stands, then they switch positions as they work.

So chronological: Two people, one in black shirt and jeans (kneeling, gloves) and another in black shirt and jeans (standing), are at the rear of a black car. The kneeling person works on the wheel, while the standing person assists by moving closer. They then both kneel to continue the tire change. The spare tire is near them. Background has a house with a garage door, but minimal. Camera is static, no movement.

Wait, let's check the rules: focus on motion and behavior chronologically. So step by step:

- At the beginning, one person (black shirt, jeans, gloves) is kneeling by the rear wheel of a black car, handling the wheel. Another person (black shirt, jeans) stands nearby.
- The standing person moves toward the car, then kneels to assist.
- The standing person then stands up, steps back, and the kneeling person continues working.

Wait, the video frames: [0.0] shows the kneeling person, the standing person. Then [1.4] the standing person moves closer, the kneeling person is still on the ground. [2.5] the standing person is now standing to the right of the kneeling person, who is still on the ground. [3.6] the standing person is on the right, the kneeling person is on the left, both working. [4.7] the standing person steps back and moves away from the car, while the kneeling person remains.

So the sequence of actions:

1. A person in a black shirt and jeans kneels to the left of a black car's rear wheel, working on it.
2. Another person, also in a black shirt and jeans, stands near the wheel.
3. The standing person moves closer, then kneels beside the first person to assist.
4. After working together, the standing person stands up and walks away from the car, while the other person continues working.

Now, the camera perspective: the video shows a static shot, no apparent movement (no pan or zoom).

Need to mention spatial relationships: the two people are at the rear of the car, one kneeling left of the wheel, the other standing nearby. Then the standing person moves closer and kneels, then steps back.

Also, background: the car is parked outside a house with a garage, some trees, but minimal.

Now, the caption must be concise. Let's structure:

Two individuals, both wearing black shirts and jeans, work on the rear wheel of a black car. One person kneels to the left of the wheel, handling it, while the other stands nearby. The standing person moves closer, kneels to assist, then stands up and steps back away from the car

Two people are engaged in physical interaction with a stationary car and tools; one person is kneeling and handling items, while the other stands and moves around the car, performing actions like lifting and positioning.

The background elements (house, trees, ground) are stable with no significant shifting or environmental fluid motion (fire, water, wind) observed. Background remains consistent throughout the video.


A man in a beige uniform and hat stands near a palm tree with red markings, then walks left toward a large cylindrical log structure, reaching up to interact with it. He moves quickly across the frame, positioning himself to the left of the structure. The background consists of dense green foliage and trees. The camera remains stationary throughout the sequence.

A person (solid, distinct object) is moving: walking, gesturing, and interacting with a pole structure. Motion is due to explicit locomotion and handling objects.

Background elements (trees, wooden structure) remain stationary; no shifting backgrounds or fluid/environmental motion (fire, water, wind) observed.


A child in red shorts pushes a swing at a wooden playground structure, causing another child to oscillate back and forth. The pusher alternates positions near the swing set while the swing moves. The camera maintains a top-down perspective with slight movement, overlooking a grassy yard.

A child in red shorts is swinging back and forth on a swing, driven by physical forces (pendulum motion). The swing set structure and the second child standing nearby are static.

The background (grass, swing set structure, building) remains stationary with no uniform shifting or fluid motion. No fire, water, smoke, or significant wind effects are present.


A child in a pink top and blue pants moves rapidly across the room, then runs toward the right side where another child in a dark shirt and white pants emerges from behind a refrigerator. The first child sits on the wooden floor in front of a black media console. The camera pans right to follow the first child’s movement and remains static as she settles.

Two children (one in pink, one in blue) exhibit distinct motion: the pink-clad child performs a handstand, crawls, and sits; the blue-clad child jumps, runs, interacts with the refrigerator, and moves across the floor.

The background elements (walls, refrigerator, kitchen area) remain stationary with no uniform shifting, and there is no fluid/environmental motion (fire, water, smoke) present.


A woman in a gray tank top, black shorts, and red sneakers sits on a large green exercise ball, leans back, stands up, and pushes the ball forward while moving to its side. A red exercise ball and green railing are visible nearby in the gym setting. The camera remains static.

The child (discrete object) moves via physical locomotion: shifting weight on the green exercise ball, leaning forward, and touching the ball with hands/feet.

The brick wall, green railing, and floor are static; no shifting background or fluid/environmental motion (fire, water, wind) is present.


A light brown and white cat, with a fluffy coat, is seen close-up licking its paw while resting against a person's arm. The cat's tongue extends as it grooms, its head moving slightly in the frame. The background includes a partially visible sign but remains out of focus. The camera maintains a close-up perspective with minor handheld movement.

A cat is actively moving its head and tongue to lick a black object (likely another animal), while a human hand moves to pet the cat. Both objects exhibit clear physical motion driven by voluntary actions.

No shifting background elements or fluid/environmental motion (fire, water, wind) detected; wall with papers and window remain stationary throughout the clip.


A person wearing a light gray t-shirt and gloves stands beside a large white sculptural piece on a workbench. They hold a tool in one hand and a green hose in the other, then turn to direct the hose toward the sculpture’s surface, moving it across the form. The individual adjusts their stance and hand position while working. The scene features a stationary camera with minimal background details including storage cabinets and tools visible behind the work area.

A man (discrete object) is moving his arms and body while interacting with a sculpture and a green hose-like tool, exhibiting deliberate locomotion and tool manipulation.

Static background elements (cabinets, walls) show no uniform shifting; no fire, water, smoke, or wind motion observed.
