Three people stand around a table with a rectangular cake covered in white frosting and black decorations. A person in a white shirt moves toward the cake, leans over it, and begins cutting, while the other two—wearing a dark blue shirt and a gray shirt—observe. The camera remains relatively stable with minor adjustments during the action.

Discrete solid objects: Children (in white, dark blue, and gray shirts) moving. The child in white shirt cuts the cake and leans forward; the child in dark blue shirt shifts from sitting to standing; others observe and adjust positions.

No shifting background elements; no fire, water, smoke, or wind observed. Walls and furniture remain stationary throughout.


A child in a green and black vest and blue pants, carried on shoulders, holds a red box while another child in a light blue jacket approaches from the left, takes the box, and both adjust it together. The camera follows with a slight shake as they move in a grassy yard with a shed in the background.

Two people interacting: one holding a child on their shoulders, the other extending a red box toward the child. The child and box are discrete objects in motion due to physical interactions (e.g., hand movements, box transfer).

Background elements (house, grass, trees) show minimal uniform shifting. No dominant fluid/environmental motion (fire, water, smoke) detected; tree sway is subtle and not the primary focus.


RAW CAPTION: Got it, let's break this down. The video shows a child lying on sand. First, the child is on their stomach, then moves. Let's check the frames. The child is wearing a blue shirt and shorts. They start in a prone position, then shift, maybe moving their arms and body. The background has some green objects and debris, but we need minimal background. Camera perspective: seems like a steady shot, maybe slightly tilted. Need to describe chronological motion: the child is on sand, moving limbs. Let's structure it.

Main subject: a child (appears as a small person, blue shirt, shorts). Motion: starts lying on stomach, then moves arms and body, possibly crawling or shifting position. Spatial: on sandy ground, background has some green items (but keep minimal). Camera: no significant movement, maybe a slight angle. Conclude with camera perspective.

Wait, rules say: chronological paragraph, concise. So start with the action. "A child in a blue shirt and shorts lies prone on sandy ground, moving their arms and upper body while shifting position. The camera maintains a steady, slightly angled perspective, capturing the child's motion against a sparse background with minimal debris."

Wait, check rules. "Focus on motion and behavior... chronological order." So first frame: child lying on sand, then moves. Let's make it flow.

"A child wearing a blue shirt and gray shorts lies on their stomach in the sand, moving their arms and torso. They shift position slightly, adjusting their limbs as they remain on the ground. The camera captures this from a top-down angle with minimal movement, keeping the background sparse and out of focus."

Wait, "top-down" – in the video, the camera seems to be looking down, but maybe not. Let's check the frames: the first frame shows the child lying, the camera is positioned above, so top-down. But maybe "slight angle". But the instruction says "conclude with camera perspective".

Also, background descriptions minimal. So only mention if essential. The green object in the background is maybe a toy, but since it's minimal, maybe just "sparse background".

Let me try to write:

"A child in a blue shirt and patterned shorts lies prone on sandy ground, moving their arms and upper body as they shift position. The camera remains stationary at a slight angle, capturing the child's motion against a minimally detailed background."

Wait, check the video: the child is lying, then moves arms, maybe trying to get up. Let's be precise.

First frame: child lying on stomach, arms extended. Second frame: similar, but body shifted. Third frame: arm moving. Fourth: arm further. Fifth: more movement. So the child is moving their arms and body, maybe attempting to crawl or adjust.

So chronological: "A child in a blue shirt and gray shorts lies on their stomach on sandy ground, moving their arms and torso in a slow, deliberate manner as they shift position. The camera maintains a steady, slightly angled perspective, focusing on the child's motion with the background remaining out of focus and sparse."

Wait, but need to keep it concise. Let's make it shorter.

"A child wearing a blue shirt and gray shorts lies prone on sandy ground, moving their arms and upper body while shifting position. The camera captures this from a top-down angle with minimal movement, against a sparse background."

Wait, check rules: "Exclude text recognition, named characters, or stylistic analysis." So no names, just describe.

Let me structure:

- Main subject: child (small, blue shirt, gray shorts, lying on stomach)
- Motion: moves arms, shifts body position over time
- Background: minimal, sandy ground with some debris
- Camera: top-down, steady, slight angle?

Wait, the video frames show the child's movements, so the caption should be chronological.

So: A child in a blue shirt and gray shorts lies on their stomach in the sand, moving their arms and torso as they adjust their position. The camera maintains a steady, slightly angled perspective, capturing the child’s motion against a sparse background with minimal debris.

Yes, that's concise. Let's check the rules:

a) Motion and behavior chronological: yes, describes the movement over time.

b) Appearance: blue shirt, gray shorts, small person.

c) Spatial: lying on sand, background sparse.

d) Camera: steady, slightly angled, top-down? Maybe "steady, slight angle".

e) Background minimal: yes, "sparse background with minimal debris".

f) Excluded text, names: no.

g) Output format: tags.

So final caption: "A child in a blue shirt and gray shorts lies prone on sandy ground, moving their arms and torso as they shift position over time. The camera captures this from a steady, slightly angled perspective against a sparse background with minimal debris."

Wait, but "

The child is making small movements with arms and legs, indicating self-initiated motion.

The background (ground and vegetation) is static. No fire, water, or wind effects observed.


A basketball player in a white jersey and orange shorts holds a ball, then dribbles forward on the court, jumps to shoot toward the hoop, and the ball passes through the net as the player continues running past; the camera follows the player’s movement, panning slightly to the basket with a large crowd visible in the background.

discrete_object_physics | ambient_environmental | camera_motion | ego_motion | static

The basketball player (number 22) is moving (running, jumping, landing, walking) and the basketball is moving (shot and going through the hoop). These are discrete objects moving due to physical forces and locomotion.

The stadium background (stands and court) is shifting uniformly, indicating camera motion. There is no fluid environmental motion (fire, water, wind) present. The crowd movement is discrete and not ambient.


RAW CAPTION: Got it, let's break this down. The video shows two people: one in a crib and another jumping. First, the person in the crib is lying down, maybe a child. Then the other person (adult?) jumps over the crib. The sequence: start with the jumper in mid-air, then lands, maybe the crib kid looks up, then jumper jumps again. Need to note the motion chronologically.

First, the jumper is in the air above the crib, then lands on the other side, then jumps again. The child in the crib is initially lying down, then looks up as the jumper lands or moves. Appearance: the jumper is wearing a dark shirt, the child in crib has light hair, maybe a gray shirt.

Spatial: jumper is behind the crib, jumps over. The crib is central. Background: fireplace, but minimal as per rules.

Chronology: 0.0s: jumper starts jumping. 1.4s: jumper is in mid-air, child looks up. 2.5s: jumper lands on the other side (maybe), then jumps again. 3.6s: jumper is again in mid-air. 4.7s: jumper is lower.

Wait, need concise. "A person in a dark shirt repeatedly jumps over a white crib containing a child with light hair wearing a gray shirt. The jumper’s movements cause the child to look up. The jumper is positioned behind the crib, leaping over it while the child remains in the crib. Camera remains stationary, capturing the motion from a fixed angle."

Wait, need to follow rules: chronological order. Start with what happens first. At the start, the jumper is jumping (first jump), then lands, maybe the child reacts, then jumps again.

"Starting with the jumper in mid-air above the crib, the person in a dark shirt leaps over the white crib containing a child with light hair and a gray shirt. As the jumper lands behind the crib, the child looks up. The jumper then jumps again, moving above the crib, while the child remains seated. The camera remains stationary, capturing the motion from a fixed perspective."

Check rules: a) motion and behavior chronologically. b) appearance: dark shirt, light hair, gray shirt. c) spatial: behind the crib, over the crib. d) camera: stationary, fixed. e) background minimal (fireplace mentioned but maybe too much, but rules say minimal unless essential. The fireplace is in the background, but maybe not essential for motion. So focus on the action.

Possible caption:

"A person in a dark shirt jumps over a white crib containing a child with light hair wearing a gray shirt. The jumper's repeated leaping motions occur behind the crib, causing the child to look up. The camera captures this sequence from a stationary, eye-level perspective."

Wait, but need to be more chronological. The video starts with the jumper jumping (0.0s), then the jumper is in mid-air (1.4s), then jumps again (2.5s), then again (3.6s), then lands (4.7s). Wait, the timestamps show the motion: at 0.0s, the jumper is in the air, then 1.4s the jumper is behind the crib, 2.5s again in air, 3.6s landing, 4.7s lower.

But perhaps simplify: "A person in a dark shirt repeatedly jumps over a white crib with a child inside. The child, wearing a gray shirt and light hair, looks up as the jumper moves. The camera remains stationary, capturing the action from a fixed angle."

Wait, the main subjects: two people. One is in the crib (child), the other is jumping (adult). Chronological: jump, land, jump again. The child is initially looking down, then looks up when the jumper is moving.

Let's structure:

At the start, the jumper is airborne above the crib. The child in the crib, with light hair and gray shirt, is seated. The jumper then lands behind the crib. The jumper jumps again, leaping over the crib while the child looks up. The camera remains stationary, capturing the motion from a fixed perspective.

Check all rules:

a) Motion chronologically: start with jump, then landing, then jump again.

b) Appearance: jumper (dark shirt, adult size), child (light hair, gray shirt, in crib).

c) Spatial: jumper behind crib, jumping over it.

d) Camera: stationary, fixed perspective.

e) Background: minimal, maybe just note the room has a fireplace but not necessary. So focus on action.

So final caption:

"A person in a dark shirt repeatedly jumps over a white crib containing a child with light hair and a gray shirt. The jumper’s movements occur behind the crib, causing the child to look up. The camera

Two children are visible; one is in a crib, while the other is actively jumping and moving within the crib space. The jumping motion is a discrete physical action driven by the child's locomotion.

The static background elements (fireplace, wall decorations, purple wall) show no uniform shifting across frames, and there are no fluid/environmental phenomena (fire, water, smoke, wind) dominating the scene.


Several people seated around a table manipulate blue and white tiles on a green surface, moving and stacking them with their hands. The group, including individuals in dark jackets and a person in a red patterned shirt, are positioned closely around the table, engaging in the game. The camera captures the scene from a top-down perspective with slight movement, maintaining focus on the table and the players' hands as they interact with the tiles.

Hands and game tiles (solid objects) are moving due to physical interactions (picking up, placing tiles) as part of a board game, with clear motion tracking of discrete objects.

No shifting background elements or fluid/environmental motion (fire, water, wind) detected; the background remains static with no signs of environmental influence.


A young child in a light striped shirt sits and flips through an open newspaper, turning pages with both hands while shifting focus between sections. The child’s hands move across the paper as they navigate through the pages, maintaining a seated position. The scene is viewed from a top-down perspective with minimal background details visible.

The child's hands are actively turning the pages of the newspaper, causing discrete movements of the newspaper as it flips.

The background (wooden walls and chair) is static with no shifting or environmental motion (fire, water, smoke, wind) detected.


A small child in a white shirt and shorts starts on the floor, then stands and walks across the room from left to right toward a table with toys, moving toward the back of the room. The camera remains stationary throughout.

A child (solid object) moves from sitting to standing and walks across the room, demonstrating locomotion driven by physical forces.

Background elements (walls, furniture, floor) remain stable with no uniform shifting or fluid motion. No fire, water, smoke, or wind effects are visible.


A person in a black shirt with white-cuffed sleeves adjusts a brass alto saxophone's keys with both hands, then brings the instrument to their mouth to play. The camera starts with a close-up of the hands on the saxophone, transitioning to a medium shot showing the upper body and the playing motion. The background remains plain and unobtrusive.

The saxophone is being played by a person; the hands move the keys and the mouthpiece, and the player's head may adjust slightly. These are discrete, solid object movements controlled by the musician's actions.

The background is static and uniform (white/light gray) with no visible fluid motion (fire, water, smoke, wind) or shifting elements. The background does not shift uniformly, so no camera motion is evident.


A white dresser with multiple drawers serves as the background. A hand holding a gray fuzzy object and two yellow knitting needles enters the frame, inserting the needles through the fuzzy material. The hand manipulates the needles within the object, adjusting their position against the dresser. The camera remains stationary throughout.

A hand holds a yellow crochet hook and manipulates gray yarn in rhythmic crochet motions, with discrete movements of the hook and yarn fibers.

The white dresser background remains static throughout the video with no shifting or environmental fluid motion (fire, water, smoke, wind).


A person wearing a green hoodie and black beanie sits at a wooden table, initially holding a phone with both hands. They then extend their right hand to pick up a stack of cards from the table, briefly holding them before returning to focus on the phone. The camera remains stationary, capturing the subject from a frontal angle in an indoor setting with a blurred wall and indistinct background elements.

Discrete solid objects (people, phone, small items on table) exhibit intentional motion: hands manipulating phone, handling small objects on table, and head movements.

Background elements (tiled walls, table) remain static with no uniform shifting or fluid motion. No fire, water, smoke, or wind present.


A woman in a dark top and white shorts sits on a wooden bench with metal armrests, petting a black medium-sized dog that stands on its hind legs in front of her. The dog remains upright while she continues stroking its head and neck. The camera remains stationary throughout the sequence.

A seated woman is holding and moving a small dog on her lap; the dog's movement is due to the woman's hand actions.

Background (walls, whiteboard, posters) is static with no shifting. No environmental motion (fire, water, wind) observed.


A person in a white short-sleeved shirt and white hairnet bends over a large white sink filled with a yellowish liquid. They dip a white cloth into the liquid and scrub the sink’s interior in circular motions. Behind them, shelves hold stacked white items. The camera follows the person’s movements with a slight pan to the right.

A person (solid, distinct) moves their arms and body to wash an object in a container, involving physical interactions like dipping, stirring, and lifting.

Static background elements (walls, shelves) show no uniform shifting; the liquid in the container is a secondary element being manipulated, not dominant ambient motion (e.g., flowing water or smoke).


RAW CAPTION: Got it, let's break this down. The video shows a track and field event, probably a javelin or discus throw? Wait, the main action: a person is in a circle (the throwing area), then steps out. Let's check the frames.

First frame: person in yellow shirt (maybe volunteer) and others around a circular platform. Second frame: someone in white shirt is stepping out, maybe throwing. Wait, the person in the white shirt is moving from the circle. Let's track the sequence.

Frame 0: A group of people, some in yellow vests (with "SQUAD" maybe), around a circular white platform on red track. One person in white shirt is near the platform.

Frame 1: The person in white shirt is stepping off the platform, others around.

Frame 2: They're moving forward, others watching.

Frame 3: The person is running, then turns.

Wait, the main subject: the athlete. Let's focus on motion. The athlete is in the throwing circle (platform), then steps out, runs, and then the scene shows them moving. Wait, no: the video starts with the athlete in the circle, then they step out, and others (volunteers) are around.

Wait, the caption needs chronological order. Let's list the steps:

- Initially, several people (volunteers in yellow shirts, some in other colors) stand around a circular platform on a red track. One individual (athletic wear, white top and dark shorts) is in the platform.

- Then, the individual steps off the platform and begins moving forward (running or walking).

- The volunteers and other onlookers are positioned around the platform, some moving slightly.

Wait, let's check the frames. Frame 0: person in yellow shirt (left) and another person (center) near the platform. Frame 1: the person in white shirt steps off, others (yellow shirts) are around. Frame 2: they continue moving, then frame 3: the person is walking away, others still around.

So main subject: the athlete (white top, dark shorts) steps out of the circular platform and walks forward. Volunteers in yellow shirts are near, some moving. Others in the background (blue shirts, etc.) are stationary.

Now, appearance: athlete in white top, dark shorts; volunteers in yellow shirts with text (but exclude text, so just yellow). Number: multiple people (volunteers and onlookers).

Spatial: the athlete is in front of the platform, then moves away. Volunteers are around the platform.

Chronological: Athlete steps off the platform, then moves forward as volunteers adjust positions.

Camera perspective: seems to be a steady shot, maybe slight pan to follow the athlete's movement.

Now, write concisely.

First, describe the main motion: An athlete in a white top and dark shorts steps out of a circular platform on a red track, then walks forward. Around the platform, several individuals in yellow shirts move and stand, some adjusting positions. Background includes other people, but minimal. Camera remains relatively steady, capturing the athlete's movement from a frontal perspective.

Wait, check the rules: exclude text recognition, so no "SQUAD" etc. Mention appearance: white top, dark shorts; yellow shirts (but no text).

Let's structure:

"An athlete in a white top and dark shorts steps from a circular white platform on a red track, then walks forward while several individuals in yellow shirts stand and move around the platform. The camera remains steady, observing the athlete's movement from a frontal angle."

Check rules:

a) Motion: steps from platform, walks forward.

b) Appearance: athlete (white top, dark shorts), yellow shirts (number: several).

c) Spatial: athlete steps off platform, volunteers around.

d) Camera: steady, frontal.

e) Background minimal.

f) No text.

That's good.

Wait, in frame 3, the athlete is running? Wait, let's check again.

Frame 0: athlete (white top) is on platform.

Frame 1: stepping off, then moving.

Frame 2: continues moving.

Frame 3: athlete is running, moving forward.

Wait, maybe "steps off the platform and runs forward".

Yes, the video shows them running. So:

"An athlete in a white top and dark shorts steps off a circular white platform on a red track and runs forward, while several individuals in yellow shirts stand and move around the platform. The camera remains steady, capturing the athlete's movement from a frontal angle."

Yes, that's better. "Steps off" and "runs forward".

Check if the platform is white: yes, the circular platform is white.

So the caption would be:

<caption_output>An athlete in a white top and dark shorts steps off a circular white platform on a red track and runs forward,

Multiple solid objects (athletes, officials in yellow vests) exhibit locomotion (walking, running, positioning) due to physical forces.

The red wall and track surface remain static; no shifting background elements or fluid/environmental motion (fire, water, smoke, wind) observed.


A person wearing a plastic cape sits while another individual with white gloves applies a black substance to their hair, spreading it evenly from the top of the head downward. The gloved hands move methodically, massaging the product into the hair. The background includes a wooden bookshelf and a door, but the focus remains on the hair treatment. The camera remains stationary throughout, capturing the procedure from a fixed angle.

A gloved hand moves rhythmically to apply a dark substance to a seated person's hair. The hands and hair exhibit controlled, deliberate motion due to manual application.

The background (cabinets, shelves, and wall) remains static throughout the video with no shifting or motion. No fluid, fire, water, or wind effects are present.


A person in a red shirt and black pants stands before a wall, spraying red paint in continuous motion to create graffiti. They move laterally across the wall, turning to spray from different angles while maintaining a steady position relative to the wall. The individual shifts orientation, facing away from the camera at times, as they extend their arm to cover various sections. The scene occurs in a room with a green curtain to the left and a wooden door to the right; the camera remains stationary throughout the sequence.

A person in a red shirt is actively moving (kneeling, standing, repositioning) while spraying graffiti on a wall. This is a solid, distinct object exhibiting locomotion due to physical forces (muscle movement).

The background elements (walls, wooden board) show no uniform shifting or fluid motion; there are no fire, water, or smoke present, so ambient environmental motion is not dominant.


RAW CAPTION: Got it, let's tackle this. First, the video shows a dartboard. There are two red darts already on the board. Then hands enter the frame. The hands are moving, taking darts off the board. Let's check the steps.

First, the initial frame: darts on the board. Then a hand (left hand?) is on the left side, maybe holding something. Then the right hand comes in, pulls a dart from the board. Then the left hand also moves to pull another dart. Wait, the video is split into frames. Let's see the timestamps.

Frame 0: two red darts on the board. Frame 1: hands move, one is on the left, pulling a dart. Frame 2: hands are actively removing darts. Frame 3: hand continues pulling. Frame 4: hand pulls the second dart. Frame 5: the board now has no darts, and hands are moving away.

So the main subject is the hands removing the darts. The darts are red, maybe two darts. The board is in front of a piano. But background is minimal. So the caption should focus on the action: hands removing red darts from the dartboard. Chronological: start with darts on board, then hands remove them.

Need to mention the motion: hands (two, maybe) take darts off. Appearances: red darts, hands. Spatial: hands in front of the dartboard, which is near a piano (but background minimal, so maybe just "a piano is visible to the right"? Wait, rule e says minimal background unless essential. The piano is part of the background, but maybe it's okay to mention if it's part of the scene. Wait, the dartboard is on the piano? No, the piano is behind the dartboard, right? The dartboard is positioned next to the piano, with keys visible.

But rule e: minimal background. So maybe just note the piano is in the background, but since it's part of the setting, maybe include it briefly. Let's see.

The hands are removing the darts. Let's describe the order:

1. Initial state: two red darts embedded in the dartboard, with a piano visible behind it.
2. A hand enters from the left, reaches towards a dart, pulls it out.
3. Another hand (or same hand?) pulls the second dart out.
4. Both darts are removed, hands withdraw.

Now, check appearance: hands are light-skinned, arms in black sleeves? Wait, in the frames, the hands are in dark sleeves. So "dark-sleeved hands".

Chronological order: hands remove two red darts from the dartboard, with a piano visible in the background to the right. Camera is fixed, close-up shot.

Wait, the camera perspective: the video is a close-up of the dartboard, so camera is static, top-down? No, it's a side view, but close-up. The caption should say camera perspective: close-up, fixed.

Let's structure the caption:

A pair of dark-sleeved hands removes two red darts from a dartboard positioned next to a piano, with the hands first pulling one dart from the board then the second, followed by withdrawing the darts; the camera maintains a fixed close-up perspective throughout.

Wait, check rules: focus on motion and behavior in chronological order. So start with the darts being present, then hands act.

"Initially, two red darts are embedded in the dartboard. A pair of dark-sleeved hands enters the frame, with one hand removing the first dart and the second hand removing the second dart from the board. The darts are fully extracted, and the hands retract. The dartboard is positioned to the left of a piano visible in the background, with the camera maintaining a fixed close-up view."

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

"Two red darts are on a dartboard beside a piano. Dark-sleeved hands enter, removing both darts one after the other; the hands pull each dart from the board and withdraw, with the camera maintaining a static close-up view."

Check if background is minimal: piano is visible, but maybe it's necessary. The problem says "minimal unless essential for understanding motion." The motion of removing darts doesn't depend on the piano, but it's part of the scene. So mention it briefly.

Alternatively, "Two red darts are on a dartboard; dark-sleeved hands remove both darts sequentially, pulling each from the board and retracting, with the camera fixed in a close-up position."

Wait, need to mention the number of darts (two) and their color (red). Hands are dark-sleeved.

Let me check the frames again. Frame 0:

Hands are manipulating darts on a dartboard, removing them from the board. The darts are solid objects moving due to human interaction.

The background contains a piano keyboard and other static elements that show no uniform shifting or fluid motion. No fire, water, or smoke is present.


A person in a red sleeveless top and red shorts stands on a concrete throwing circle, facing away from the camera, with a chain-link fence behind. They begin by swinging their right arm back, then rotate their body clockwise while extending their arm forward to release an object. After the throw, they step back onto the circle, completing the motion. The background includes grassy fields and a distant figure near the fence. The camera remains stationary, capturing the action from a fixed angle with minimal movement.

A person in red athletic wear is the discrete object moving. They exhibit rotational motion (spinning) and a throwing motion, driven by explicit physical forces (muscle contraction for rotation and release).

The background (chain-link fence and grassy field) shows no shifting, fluid, or environmental motion (e.g., wind-blown grass, smoke, or water). Static elements remain fixed throughout, indicating no ambient environmental dominance.


A person with short dark hair wearing a black shirt stands in front of an open refrigerator in a dimly lit kitchen. They shake a container, releasing thick white vapor that billows outward. The camera remains stationary, viewing the scene through a doorway.

A person is moving their arms and body, interacting with objects (e.g., opening the refrigerator, handling items inside).

The background elements (refrigerator, shelves, window) remain stationary and show no fluid/environmental motion (fire, water, smoke, wind).


A person in an orange shirt stands at a kitchen counter, pouring liquid from a bottle into a bowl, while a child in a dark blue shirt sits to the right, handling food items. The adult moves slightly during pouring, and the child remains seated, focused on their task. The camera maintains a steady perspective with minimal movement, capturing the scene from a medium distance.

Two individuals (adult and child) are moving their hands and bodies in the kitchen; adult appears to be preparing something while child is seated and interacting with objects.

Kitchen background (cabinets, window) is static; no fire, water, smoke, or wind observed.


RAW CAPTION: Got it, let's break this down. The video shows someone opening a coconut. First, the person uses a tool to make a hole in the coconut. Then they insert a metal grater or something to extract the coconut water. Wait, the steps: the person's hands, they're using a tool (maybe a knife or coconut opener) to pierce the coconut, then a grater to scoop out the water. The main subject is the person's hands, wearing a blue jacket. The coconut is brown, on a white surface. Background has mulch and maybe a fence. The camera is close-up, following the actions. Let's make it chronological. Start with the person using the tool to make an incision, then using the grater to draw out the liquid. Keep it concise.

So: A person wearing a blue jacket uses a dark-handled tool to pierce a brown coconut resting on a white surface. They then insert a metal grater with multiple holes into the incision, moving it in a twisting motion to extract liquid. The camera maintains a close-up perspective, following the hands and tools as they interact with the coconut. Background elements like mulch and a fence are partially visible but not central to the action.

Wait, need to check rules. Focus on motion and behavior. Main subjects: person's hands (blue jacket), coconut (brown), tool (dark handle), grater. Chronological: first piercing, then using grater. Spatial: coconut on white surface, person's hands above. Camera is close-up, maybe slightly shaky? The video shows close-up of hands, so camera is close. No mention of background being essential, so minimal. Let's structure:

A person wearing a blue jacket uses a dark-handled tool to pierce a brown coconut placed on a white surface. They then insert a metal grater into the incision and move it in a twisting motion to extract liquid from the coconut. The camera remains close-up throughout, focusing on the hands and tools, with the background featuring mulch and a partially visible fence.

Wait, but rule e says minimal background. So maybe just mention if essential. The background (mulch, fence) isn't essential for motion, so maybe omit? Wait, the first frame shows mulch, but maybe not necessary. Let's check. The main action is hands on coconut, tools. So background can be minimal. Let's see the example in the problem. The rules say "exclude text recognition, named characters, or stylistic analysis. Keep background descriptions minimal unless essential for understanding motion."

So if the background isn't essential, just say "background shows mulch and a fence" but maybe not. Let's check the video frames: first frame has mulch, maybe a fence. But the motion is the hands and coconut, so maybe background is not essential. So perhaps just "background shows mulch" but the rules say minimal. So maybe skip background if not necessary. The problem says "if relevant", so if it's not relevant, don't mention. So focus on the action.

So revised: A person wearing a blue jacket uses a dark-handled tool to pierce a brown coconut on a white surface. They then insert a metal grater into the incision and twist it to extract liquid. The camera stays close-up, following the hands and tools as they interact with the coconut.

Wait, but the person is holding the tool in one hand and the grater in the other. Let's check the video steps:

Frame 0: hands holding tool (maybe a cleaver) and grater.

Frame 1: tool inserted into coconut.

Frame 2: tool and grater in position.

Frame 3: twisting the tool into the coconut.

Frame 4: using the grater to scoop.

Wait, maybe the steps are: pierce the coconut with the tool, then use the grater to extract. So the sequence is inserting the tool, then using the grater.

So in caption: A person wearing a blue jacket uses a dark-handled tool to pierce a brown coconut resting on a white surface. They then hold a metal grater with multiple holes against the incision and twist it to extract liquid. The camera maintains a close-up view of the hands and tools interacting with the coconut.

Check rules:

a) Motion chronological: pierce first, then use grater.

b) Appearance: blue jacket, brown coconut, metal grater with holes, dark tool.

c) Spatial: coconut on white surface, hands above.

d) Camera: close-up, maybe no movement mentioned (the video shows close-up, so "maintains close-up").

e) Background minimal: maybe omit since not essential.

f) No text, no names.

So final caption: A person wearing a blue jacket uses a dark-handled tool to pierce a brown coconut on a white surface. They then insert

A person's hands and a tool (e.g., knife/spike) interact with a coconut; the tool is inserted into the coconut and manipulated by the hands.

Background elements (concrete surface, soil) are static; no fluid or environmental motion (fire, water, smoke, wind) observed.


A person in a green jacket, black pants, and helmet skis across a snow-covered slope, using ski poles to propel forward and gradually turning right while maintaining balance. A small snow-covered structure is visible to the left. The camera remains stationary with a slight shake.

A single skier (wearing a green jacket and black pants) is moving across the snow using ski poles. The skier's motion is discrete, locomotive, and consistent with intentional physical movement on skis.

The snow-covered ground, trees, and bench in the background show no shifting or fluid motion. No fire, water, or smoke is present; the environment is static with undisturbed snow, indicating no dominant ambient environmental motion.


A person wearing a white and black short-sleeve shirt and dark pants repeatedly jumps in place near a wooden door with a glass panel on the left side of the frame. The individual begins standing, lifts their legs upward while bending knees, then extends limbs outward during the jump, repeating the motion several times. The background includes a white wall with three framed items to the right of the door, with minimal environmental details beyond the doorframe and wall. The camera remains stationary throughout the sequence, capturing the motion from a fixed, eye-level perspective.

A person wearing a white/black shirt and green pants is the primary moving object. The individual exhibits locomotion (walking/jumping) through a doorway, causing motion blur due to rapid movement and low frame rate.

The background elements (wooden door with frosted glass, wall with three framed pictures) remain stationary and consistent across all frames. No fluid motion (fire, water, smoke, wind) or environmental effects are present.


A person with pink nail polish holds a brown and white bulldog's mouth open, using a yellow toothbrush to brush the dog's teeth. The hand stabilizes the dog's jaw while the toothbrush moves inside the mouth. The camera remains close-up and static throughout, focusing on the brushing action against a dark background.

A person's hands (with red nail polish) and a yellow toothbrush are interacting with a dog's mouth. The hands and toothbrush move in a deliberate, rhythmic motion to clean the dog's teeth, exhibiting discrete, solid-object motion.

The background consists of a dark, static surface (likely a table or floor) with no shifting or fluid motion observed. No fire, water, smoke, or wind-induced motion is present.


Two individuals sit across a small wooden table; one wears a light straw hat, the other a dark cap. They simultaneously lean forward, bending over the table to inspect an object, then gradually straighten while maintaining proximity to the table surface. The camera remains static with minimal handheld shake.

Two people wearing hats are interacting at a table: one leans forward to manipulate objects (likely cards), while the other leans in to observe or assist. Their hands and upper bodies move intentionally due to explicit physical actions.

Background includes walls, framed artwork, and furniture with no shifting or fluid motion (no fire, water, smoke, or wind observed). Static elements like the door and wall decorations remain consistent throughout.


A young girl in a striped shirt and jeans sits cross-legged on a green rug with a globe design, tying her shoelaces. An adult in a dark shirt stands to her right, gesturing with their hands while shifting position slightly. The background features a wall with colorful posters and a light switch. The camera remains stationary, capturing the scene from a fixed angle.

The adult performs hand gestures while holding an object, and the child remains seated with minimal movement. The adult's hand motion is discrete and driven by intentional physical action.

The background (wall with posters, green rug) shows no uniform shifting or environmental fluid motion (e.g., fire, water, smoke). Static elements remain fixed across frames.


RAW CAPTION: Got it, let's break this down. The video starts with the videojug logo, but the rules say to exclude text recognition. So the first part might not be included in the caption since it's the logo. Then the next scenes: first, a person mowing a lawn with a green lawnmower. The person is wearing dark pants and sandals. Then they stop, and the camera shows them using a rake? Wait, no, the next scene is a person with a yellow-handled tool (maybe a rake or something) working on the grass. Then another scene where a person is using a measuring tool (like a ladder or measuring stake) in the garden. Wait, the timestamps are [0.0], [1.4], [2.5], [3.6], [4.7].

So the video sequence:

0.0: Logo screen (but ignore text recognition, so maybe skip as it's not motion)

1.4: Person mowing lawn with green lawnmower. Person's legs visible, dark pants, sandals. Lawnmower is green, moving across grass. Background is garden with plants.

2.5: Close-up of person's legs (dark pants, sandals) and the lawnmower, then the person pushes the mower, grass being cut.

3.6: Person using a yellow-handled tool (maybe a rake) on grass, which is a mix of green and brown. The person is standing, working on the grass.

4.7: Person using a measuring device (like a measuring rod or ladder) in the garden. The person is bending over, using the tool.

Now, need to describe in chronological order, focusing on motion and behavior.

Start with the mowing: person pushing green lawnmower on grass, then moving to using a yellow tool (rake?), then measuring.

Wait, the order is:

1.4: lawnmower (person pushing, green mower)

2.5: close-up of person's legs (dark pants, sandals) and mower, pushing.

3.6: person with yellow-handled tool on grass (maybe raking or preparing)

4.7: person using a measuring tool (lawn measuring device) in garden, bending.

So the caption should be:

A person wearing dark pants and sandals pushes a green lawnmower across a grassy area, moving the mower while the camera captures the action. Next, the person uses a yellow-handled tool to work on the grass, followed by using a measuring device in the garden, bending over to adjust it. The camera shifts between close-ups of the lawnmower and the person’s actions, then to a wider shot of the garden area. Background includes greenery but is minimal. Camera perspective changes from close-up to medium and wide shots.

Wait, need to check the rules:

a) Motion and behavior chronologically. So first mowing, then using the tool, then measuring.

b) Appearance: green lawnmower, dark pants, sandals, yellow tool.

c) Spatial relationships: person pushing mower, then using tool on grass.

d) Camera perspective: close-up, then wider shots.

e) Background minimal.

f) No text.

So let's structure:

The video opens with a person in dark pants and sandals pushing a green lawnmower across a grassy area, then shows the same person using a yellow-handled tool to clear or adjust the grass, followed by the individual bending over to measure a section of the lawn with a measuring device. The camera alternates between close-ups of the lawnmower and the person’s actions, then transitions to a wider shot of the garden setting. Background vegetation is present but not detailed.

Wait, need to be concise. Let's see:

A person wearing dark pants and sandals pushes a green lawnmower across grass, then uses a yellow-handled tool to work the grass, followed by measuring a lawn section with a device while bent over. The camera captures close-ups of the lawnmower and tools, then a wider garden scene. Background greenery is minimal.

Check if that's chronological. Yes: mowing → tool work → measuring.

Make sure to mention appearance: green lawnmower, yellow tool, dark pants, sandals.

Spatial: pushing mower (person in front of mower), then using tool (on grass), measuring (in garden).

Camera: close-ups, then wider.

Let me try to write it:

A person in dark pants and sandals pushes a green lawnmower across grass, then uses a yellow-handled tool to prepare the lawn, followed by bending over to measure a section with a device. The camera alternates between close-ups of the lawnmower and tools, then shifts to a wider garden shot. Background vegetation is present but unobtrusive.

Yes, that's concise, chronological, covers motion and appearance, spatial (pushing, preparing,

A person moves a green lawnmower across the grass and then uses a rake to gather grass clippings. The motion of the lawnmower and rake is driven by the person's physical locomotion and tool manipulation.

The background (grass, trees, bushes) remains static with no significant shifts or fluid motion. No fire, water, smoke, or wind-driven environmental motion is observed.


A woman with long curly hair wearing a patterned cardigan holds a glass and a red object, while a man in a white graphic t-shirt moves into the frame from the right. The woman lifts the glass to drink, then the man sits beside her. Both remain seated in a cluttered indoor space with minimal background detail. The camera maintains a static perspective throughout.

Two people are moving: the person on the right shifts position, turns, and interacts with the phone; the person on the left holds a cup and drinks while occasionally adjusting their posture.

The background consists of static elements like shelves, walls, and furniture. No uniform shifting of background elements is observed, and there are no fluid or environmental motions (e.g., fire, water, smoke).


A baby in a blue onesie lies on a pink fabric surface as an adult hand with a silver bracelet and ring gently repositions the infant. The hand moves the baby’s body, adjusting its position while maintaining contact. The camera provides a close-up perspective with slight movement, focusing on the interaction between the hand and the baby.

A baby (wearing a blue garment) and an adult's hands (with a bracelet and ring) are moving. The hands adjust the baby's position, indicating physical interaction.

The background (couch fabric) shows minimal movement with no fluid or environmental elements (fire, water, wind) visible. Background elements do not shift uniformly.


A woman in white clothing holds a small child in a red shirt as they walk toward a window in a room with a blue inflatable bed. The child then runs forward, leading the woman, who follows closely. The camera remains static.

Two solid objects: an adult (woman) and a child. The adult holds the child's hand, guiding her through locomotion and physical interaction (e.g., running across the room), with clear bounding box tracking of distinct movements.

Static background elements (walls, floor, blue inflatable bed) show no shifting or fluid motion. No fire, water, smoke, or wind effects observed; environment remains uniform.


A person wearing a white hooded jacket with visible text on the back and black pants with "SIMS" branding sits on a wooden floor, adjusting a red and yellow athletic shoe. They manipulate the shoe's upper and laces while seated, moving their hands to secure or fit the footwear. The camera maintains a static, top-down perspective throughout, focusing on the individual's lower body and actions against the plain wooden surface.

A person is actively manipulating their footwear (putting on shoes), with discrete movements of hands and legs visible.

The wooden gym floor background is static with no shifting or fluid motion. No fire, water, or wind-driven effects observed.


A person wearing a white shirt and dark overalls stands facing the camera, speaking while raising their right hand slightly. They then turn their head to the left, maintaining eye contact with the camera. The background includes a dark wooden cabinet with decorative items and lamps. The camera remains static throughout.

A person (human) is moving their head and hands, exhibiting discrete locomotion (head turns/nods) and gestural motion (hand movements near face).

No shifting background elements observed. No fire, water, smoke, or wind present in the scene. Background furniture (cabinet, lamps) remains static throughout.


RAW CAPTION: Got it, let's tackle this. First, I need to describe the video chronologically. The main subjects are a group of people. Let's count: there's a central person in black, and others in white shirts and dark pants. They're outdoors, trees in the background.

Looking at the sequence: the video starts with the group standing. The central person in black has arms up, then they all raise arms, then the central person moves their arms (maybe jumping or dancing), others follow. Let's break down the actions.

First frame: group standing, some raising hands. Then each frame shows more movement—arms up, then maybe swaying. The central figure in black is leading, with others mirroring. So chronological order: people start in a formation, then raise arms together, possibly moving in sync.

Appearance: central figure in black outfit, others in white tops and dark bottoms. Number: around 20-30 people. Spatial: central person in front, others behind and around. Background: trees, concrete ground.

Camera: seems static, no movement mentioned. Maybe fixed position, looking at the group.

Now, need to write a concise paragraph. Focus on motion: start with group standing, then raise arms, then move arms (like jumping or stepping), synchronized. Mention appearance briefly (central in black, others white), number (large group), spatial (central in front). Conclude camera: stationary.

Check rules: don't include text, names, stylistic. Keep background minimal. So background is trees, but not essential for motion.

Let me draft:

A large group of people, mostly wearing white tops and dark pants, gather outdoors with trees in the background. A central individual in black stands facing the group, leading synchronized arm movements. Initially, the group holds hands above their heads; the central figure then raises both arms upward, followed by the others mirroring the motion, swaying slightly in place. The camera remains stationary, capturing the group’s coordinated dance from a frontal perspective.

Wait, check number: "large group" is vague. Maybe "dozens" or count. The video shows maybe 20-30. But "large group" is okay.

Check motion: "initially hold hands above heads"—but in the first frame, they have arms up, maybe hands together. Then move. Let's check the frames. First frame: arms up, maybe hands clasped? Then next frames, the central person moves arms up, others follow.

Wait, the movement seems like a group exercise: arms raised, then maybe stepping, but the video shows the arms moving up and down. So maybe "raising arms in unison, then lowering them as a group."

But the instruction says chronological: start with how they are positioned, then their actions.

So:

A large group of people, with most wearing white shirts and dark pants and one central individual in black, stand outdoors on a concrete area with trees in the background. Initially, the group raises their arms above their heads in unison; the central figure leads the movement, then all participants follow by raising their arms higher and swaying slightly. The camera remains stationary throughout, capturing the synchronized motion from a frontal viewpoint.

Is "swaying slightly" accurate? The video shows them moving, but maybe stepping or jumping. The description should be concise. The movement is arm raising, so "raising arms in unison, then moving arms upward and downward rhythmically."

Wait, the first frame to the end: the central person in black has arms up, then they move arms (like arm circles or jumping). The group follows.

Let me check the frames:

Frame 0: group standing, arms up.

Frame 1: same, but maybe moving slightly.

Frame 2: arms up, central person moving.

Frame 3: central person stepping, arms up.

Frame 4: arms up, moving.

Frame 5: arms up, moving.

So they start standing, then raise arms, then move (dance), all in sync.

So the chronological description:

A large group of people, most dressed in white tops and dark pants with one central figure in black, stand outdoors on a concrete surface surrounded by trees. Initially, the group raises their arms above their heads in unison, with the central figure leading the motion. They continue by swaying their arms upward and downward rhythmically while maintaining their formation. The camera remains stationary, capturing the synchronized activity from a frontal perspective.

Check if "surrounded by trees" is minimal background. Yes, but it's part of the setting. But rule e says minimal unless essential. Since it's outdoors, maybe necessary. The key is the motion, so background is just trees, not essential but maybe necessary for context.

Wait, rule e: "background descriptions minimal unless essential for understanding motion." Since the motion is group exercise outdoors, maybe "trees in background" is

A group of people in white shirts and dark pants are moving in synchronized exercise motions (raising arms, stepping).

The background (trees, ground) is static with no shifting or environmental motion (fire, water, smoke, wind).


A hand manipulates poker cards on a dark table, placing them face-up near a yellow-bordered edge. The hand then moves to a tray of stacked poker chips in green, red, and yellow, adjusting their positions. The camera maintains a close-up, top-down view, focusing on the hand’s actions and the table’s surface throughout the sequence.

Discrete solid objects: dealer's hand (moving chips and cards), playing cards (being dealt and rearranged), and poker chips (shifting in the tray). Motion is explicit physical action from dealer's locomotion.

The background (poker table, yellow border, chip tray) is static with no fluid or environmental motion (fire, water, wind). The table surface remains fixed throughout the clip.


A person in a blue wetsuit swims underwater in a pool, arms extended outward. The person turns and moves through the water, as multiple gray dolphins swim into view, approaching from the right and front. The dolphins glide around the person, interacting closely. The camera maintains an underwater perspective, following the motion of the person and dolphins.

Discrete solid objects include the swimmer (in a blue wetsuit) and dolphins. The swimmer moves through the water via swimming motion, and dolphins swim independently in the background.

The video is underwater, with water movement as the ambient medium. However, static background elements (e.g., pool walls) are not clearly visible, and the dominant motion is not primarily fluid-driven (water flow itself).


A pair of hands assembles a fishing lure, beginning by adjusting a red component. They then attach a purple feather, followed by a white feather, using a fixed metallic tool to hold the lure steady. The hands manipulate the lure and feathers with precise movements, repositioning them throughout the process. The camera maintains a steady close-up perspective, focused on the hands and the lure.

Two hands manipulating a small object (appears to be a purple flower or similar craft item), with movements involving grasping, adjusting, and positioning.

The background (shirt with text) is static; no shifting elements or fluid/environmental motion (fire, water, smoke, wind) observed.


A person wearing a white shirt and dark pants jumps repeatedly across a zebra-patterned rug, moving from left to right in front of a red door. The individual leaps over the rug multiple times while the camera remains stationary, capturing the motion from a fixed position.

A person (woman) is moving across the room, dancing or running, as the only discrete solid object with significant motion.

The background (red door, wall with pictures, curtains) is static with no shifting or fluid motion. No fire, water, smoke, or wind observed.


RAW CAPTION: Okay, let's see. I need to generate a caption for this video based on the given frames. The user provided four frames, each showing different scenes.

First frame: A person in a blue hoodie and plaid shorts using crutches. They're walking on a sidewalk. The video starts with them from the back, moving forward. The person is using two crutches, so they might have mobility issues.

Second frame: The scene changes. Now it's a man in a white shirt and dark pants walking with a cane. He's near a bus with a "5" and a red circle. Wait, the bus has some text, but the rules say to exclude text recognition. So maybe just note the bus is moving or passing by.

Third frame: Another person in a black shirt and a backpack, walking down a street. There's a flower bed to the right. They're moving forward as well.

Wait, the instructions say to follow the chronological order. So the video starts with the first person, then transitions to the next scene. The user mentioned "chronological paragraph describing the provided video."

Wait, the video is a sequence of frames. The first frame is the person with crutches, then the next is the man with the cane near the bus, then another person walking. So the sequence is: 1) crutch user, 2) man with cane near bus, 3) person with backpack on street.

So I need to describe each in order. Let's check the frames again.

First frame: person in blue hoodie, plaid shorts, black shoes, using crutches on a sidewalk. The background has a street with parked cars.

Second frame: the scene shifts to a man in white shirt, dark pants, holding a cane, walking. He's in front of a bus with some symbols, maybe the bus is moving. Then another person in a light jacket with a purple bag is on the right.

Third frame: a man in black shirt, carrying a bag, walking on a sidewalk. There's a flower bed to the right.

Wait, the third frame is a different angle. The video might be panning or cutting between scenes. The task is to describe the motion chronologically, so the order of the frames is the sequence.

So the caption should start with the first person, then the second scene with the man and bus, then the third scene with the person with the backpack.

Need to keep it concise. Mention appearance (color, size, orientation), motion, spatial relationships, but minimal background.

First part: A person in a blue hoodie and plaid shorts uses crutches to walk forward on a sidewalk. Then, the scene shifts to a man in a white shirt and dark pants walking with a cane in front of a moving bus. Finally, another individual in a black shirt and backpack walks along a street with a flower bed visible to the right.

Wait, the rules say to mention spatial relationships if relevant. Like in front of, to the left. For example, the man with the cane is in front of the bus. The flower bed is to the right.

But the third frame: the person in black shirt is walking, and there's a flower bed to the right. So need to include that.

Camera perspective: The video starts with a rear view, then shifts to a side view of the man with the cane, then a different angle for the third person.

Wait, the camera movement. The first frame is from behind the crutch user, then maybe the camera follows or cuts to the next scene. The description should mention camera perspective and movement. The first part is rear view, then the camera shifts to a side view of the man with the cane, then another angle for the third person.

But the instructions say "conclude with the camera perspective and movement."

So, for example: The camera captures the initial scene from behind the crutch user, then shifts to a side view of the man with a cane walking in front of a bus, before panning to show the individual in a black shirt walking past a flower bed.

Wait, the third frame is the person with the backpack. The video might be moving from one scene to another.

Putting it all together:

A person in a blue hoodie and plaid shorts walks forward using crutches on a sidewalk, seen from behind. The scene transitions to a man in a white shirt and dark pants walking with a cane in front of a moving bus, followed by a person in a black shirt and backpack walking along a street with a flower bed visible to the right. The camera perspective shifts from rear to side views before panning across the street.

Wait, but need to be concise. Let's check the rules again.

a) Focus on motion and behavior chronologically.

b) Briefly describe appearance and number.

c) Mention spatial relationships.

d) Conclude with camera perspective and movement.

e) Minimal background.

Discrete objects include a moving bus, pedestrians walking, and a person with crutches (stationary initially then possibly moving).

Background elements (pavement, road, buildings) show no uniform shifting; no fluid/environmental motion (fire, water, smoke, wind) present.


A woman with long brown hair, wearing a dark top and gray cardigan, holds a metallic plier-like tool with both hands. She manipulates the tool by lifting her right hand while stabilizing it with her left, adjusting its position repeatedly. She stands in front of wooden cabinets, with minimal background detail visible. The camera remains static, focusing on her upper body and hands.

A person's hands are actively manipulating a small object (likely a tool or keychain) using a mechanical tool; the motion involves discrete, solid-object interactions (e.g., twisting, gripping) driven by physical forces.

The background elements (ceiling lights, wooden furniture) remain stationary with no uniform shifting, indicating no dominant ambient environmental motion (e.g., fire, water, wind) or camera-induced background shifts.


A hand presses a button on a red slot machine with three reels displaying fruit and crown symbols; the reels spin rapidly, obscuring the symbols, then stop to reveal new symbols. The hand remains in front of the machine as the reels complete their spin. The camera maintains a close-up perspective, slightly shifting to follow the machine's action.

A human hand interacts with the slot machine (pressing buttons/lever), and the machine's reels spin. These are discrete solid objects undergoing mechanical motion due to direct physical forces.

The static background elements (slot machine casing, surrounding walls) show no significant shifting or environmental fluid motion (fire, water, smoke).


A bald man in a black shirt, wearing black gloves, sits and holds a small object, then turns his head while interacting with another person. He positions a tattoo machine near the other person’s arm, which is visible in front of him; the man’s arm also displays a tattoo. The camera moves closely around the subjects with slight shakes, focusing on the tattooing motion against a cluttered background.

The bald man turns his head and moves his arm, while the tattoo artist (partially visible) uses a tattoo machine on the man's arm. The tattoo machine and the artist's hand are moving due to physical operation.

The background (cluttered room with boxes and furniture) is static with no shifting or fluid motion. No fire, water, smoke, or wind observed.


A person with long curly hair, wearing a light yellow T-shirt and dark pants, sits in a wooded area. They hold a long, cylindrical didgeridoo, bringing it to their mouth to play. The camera remains stationary, with dense foliage in the background.

A person is moving their hands and a long tube (musical instrument) to play it, which is a discrete object physics motion.

The background (trees and foliage) is static with no significant shifting or fluid environmental motion. Minimal leaf movement is present but not dominant.


A hand holding a small object slowly lowers it toward a large glass fishbowl containing a blue betta fish. As the object is released into the water, the fish swims near the surface. The hand remains positioned above the bowl throughout the sequence. The camera maintains a steady close-up perspective with no noticeable movement.

Hand holding a dropper releasing liquid drops; the motion is controlled and discrete.

Background is static. Minimal water ripples in the fishbowl are transient and not dominant motion.


A person in a pink top and dark pants is seated at a desk in a radio studio. They abruptly jump up, moving toward the right side of the frame, then land on a green chair, adjusting the microphone stand. The camera remains stationary, providing a top-down view.

A person in a pink shirt moves from lying down to sitting up, standing, and then sitting on a chair. The person's motion is due to locomotion and interaction with the chair.

The background (wall with posters and desk) is static and shows no shifting or fluid motion. No ambient environmental phenomena (fire, water, smoke, wind) are present.


A person in a dark long-sleeve shirt holds a black bass guitar with a patterned pickguard. They move their left hand up the neck while their right hand plucks the strings, adjusting grip positions. The camera remains stationary, capturing a medium close-up of the person and instrument against a dark background.

A person holding a bass guitar, with visible hand movements on the fretboard and strings while playing.

Background is dark and static with no visible shifting elements or fluid/environmental motion (fire, water, smoke, wind).


A group of soccer players on a grassy field initially cluster together, then begin running and dispersing across the field. The players, distinguishable by yellow and red jerseys, move from the center toward the camera and sides, spreading out as they run. The camera remains static, providing a wide view of the field and background trees.

Soccer players (4-5 people) and a soccer ball moving due to running, passing, and kicking; the ball's motion is driven by collisions with players and the ground.

No shifting background or fluid/environmental motion observed.


A person in dark clothing operates a white and silver floor cleaning machine with a hose, moving it across the boundary line between red and green surfaces on a tennis court. The camera remains stationary, capturing the person's forward motion.

A person (tennis player) is standing and making minimal adjustments to their stance and racket position.

The background (tennis court) is stationary with no fluid or wind motion. There is no fire, water, smoke, or wind.


A person in a gray and white plaid shirt manipulates a long, flat metal bar, moving it horizontally toward a blue vise on a cluttered workbench. They adjust the bar’s position with both hands, then shift their right hand to the side of the vise. The background features a stone wall and scattered tools, including a clear water bottle. The camera remains stationary with slight shake.

A person in a checkered shirt manipulates a metal blade and sharpening tool, with discrete motion of hands and blade during sharpening actions.

Static stone wall and workbench tools show no uniform shifting; no fire, water, or smoke present in the scene.


A woman in a white tank top and dark shorts sits on a bed holding a black bag, then stands and moves the bag across the bed, which has a white blanket and pillows. The camera remains static with slight movement.

Discrete solid objects (woman, dog) are moving: the woman manipulates the dog's position on the bed through physical contact, causing the dog to shift and reposition.

Background elements (bed, headboard, walls) show no uniform shifting or environmental fluid motion (fire, water, wind); no significant ambient environmental phenomena observed.


A hand in a white sleeve stirs a brown liquid in a rectangular metal tray, with a white bowl containing orange slices positioned to the right. The scene transitions to a whole roasted chicken with golden-brown seasoning on a white plate. The camera shifts from the tray to the chicken, maintaining a top-down perspective with slight movement.

A human hand (discrete object) is stirring the liquid in the tray. The chicken in the second segment is static.

Static background elements (stove, counter, bowl) are present and do not shift uniformly. No fire, water, or smoke is observed. The motion in the first segment is caused by a hand, not an environmental fluid.


RAW CAPTION: Got it, let's break this down. First, the video starts with a close-up of a hand holding two glowing orange objects. Wait, the first frame shows a hand holding something with green glow? Wait, no, the first frame: "a hand holds two glowing orange objects against a dark green background." Then the next frames are hands handling a white object. Let's check the timestamps.

Frame 0: Hand holds two glowing orange objects (maybe like pumpkin lights? But the description says "glowing orange objects" with green eyes? Wait, the user's input says [0.0] has a hand holding two glowing orange objects. Then [1.4] shows hands holding a white box with green and white patterns. Then they open it, revealing a green object, then close it. So the main subjects are the hands and the objects.

Chronological order: First, a hand holds two glowing orange objects (maybe like two pumpkins with green eyes, but the video's frame [0.0] is that). Then, hands handle a white box (green and white patterns), open it, show a green object inside, then close the box.

Wait, the user's input for the video:

[0.0] shows a hand holding two glowing orange objects (each with a green eye? But the description says "two glowing orange objects"). Then [1.4] shows hands holding a white box with green and white patterns. Then the hands manipulate the box: open it (turning the box, sliding fingers, etc.), revealing a green object inside, then closing it.

So the steps:

1. A hand holds two glowing orange objects against a dark green background.

2. The scene shifts to hands holding a white box with green and white patterns; the hands open the box, revealing a green object inside, then close the box.

Now, need to describe in chronological order, motion and behavior. Main subjects: hands and objects.

First frame: hand holding two glowing orange objects. Then hands handling the white box. Then opening, showing green object, closing.

Appearance: the objects are glowing orange (maybe like lanterns), hands are light-skinned.

Spatial relationships: first, hand holding objects (in front of dark green background). Then hands in front of dark green background with white box.

Background is dark green throughout, minimal.

Camera perspective: close-up, top-down? The video starts with close-up of hand, then top-down view of hands handling the box.

Let's structure the caption.

Start: A hand holds two glowing orange objects against a dark green background. Then, hands hold a white box with green and white patterns, manipulate it to open, reveal a green object inside, then close the box. Camera perspective is close-up, transitioning to a top-down view of the hands.

Wait, need to be concise. Let's outline:

- First, hands hold two glowing orange objects (describe their appearance: glowing orange, possibly with green elements? The first frame's description: "a hand holds two glowing orange objects against a dark green background" – but the video frame [0.0] has "a hand holds two glowing orange objects with green eyes" as per the user's input. Wait, the user provided the video frames as:

<0.0> shows a hand holding two glowing orange objects with green eyes against a dark green background.

Then <1.4> shows hands holding a white box with green and white patterns.

Then the hands manipulate the box: open it, slide fingers, turn, close.

So first, the hand holds two glowing orange objects (each with a green eye, maybe like pumpkin faces). Then hands handle the white box (white with green patterns), open it to reveal a green object inside, then close the box.

Chronological order:

1. A hand holds two glowing orange objects with green eyes against a dark green background.

2. The scene shifts to hands holding a white box with green and white patterns; the hands manipulate the box, opening it to reveal a green object inside, then closing the box.

Now, describe motion: holding, then opening, sliding, closing.

Appearance: the two glowing objects are orange, green eyes. The box is white with green patterns.

Spatial: first, hand in front of dark green background. Then hands handling the box (same background).

Background is dark green, minimal description.

Camera perspective: starts as close-up of hand, then top-down view of the hands and box.

Wait, the user says in the rules: "briefly describe their appearance and number (color, size, orientation)".

So:

- Hand holds two glowing orange objects (each with a green eye, so orange color, green eyes), dark green background.

- Hands (two hands) holding white box (white with green patterns), then open the box (sliding fingers, turning), revealing green object inside, then close the box

Hands holding and shuffling a stack of paper money, exhibiting clear physical movement (fanning, stacking, shuffling) due to manual manipulation.

The background is a solid dark green surface with no shifting elements or fluid motion (e.g., fire, water, smoke). The initial pumpkin-like objects are static props, not environmental motion.


A woman in a gold sequined dress and a man in black attire with a hat dance in a room with plain walls. She raises her arm, then they twirl and hold hands while moving across the space. The camera remains stationary with a slight shake.

Two solid objects (dancer in gold dress, dancer in black suit/hat) are moving: performing synchronized dance motions including spins, arm gestures, and stepping. Motion is clearly tracked with distinct bounding boxes.

The background (plain wall and dark furniture) shows no shifting or fluid motion. No fire, water, smoke, or wind is present.


A person with gray hair lies on their back under a light sheet, resting on a dark pillow. To their right, a person with short red hair and wearing a black top uses their hands to gently touch and adjust the first person’s head and face, moving their hands across the head and face. The background includes a wooden floor and a partial view of a white object. The camera maintains a top-down perspective with no movement.

Two individuals: one lying still on a bed, another using hands to massage the first person's head. The massage hands show discrete, localized motion due to physical contact and manipulation.

Background elements (wooden floor, white wall) are static with no uniform shifting. No fire, water, smoke, or wind motion detected.


A person wearing a dark jacket, light pants with a dark stripe, gray hat, and black gloves stands in deep snow holding a snow shovel. They turn their back to the camera, then begin shoveling snow forward with the tool, moving it repeatedly to clear the ground. Snow-covered vehicles and trees are visible in the background. The camera remains static throughout the sequence.

A person (discrete solid object) is shoveling snow, moving the shovel and displacing snow in a controlled manner.

The background (trees, cars) is static and stable with no uniform shifting. The snow is being displaced by the shovel but is not fluid or wind-driven as the primary motion.


A person in a red and orange jacket, black pants, and helmet sits on snow holding kite control lines. They stand up and glide forward on a snowboard as the kite flies above, pulling them across the snowy field. The camera captures the action from a low angle, slightly shaky.

The snowboarder (wearing a red jacket) is moving: initially seated, then standing, jumping, and riding away on the snowboard. This motion is due to physical forces (propulsion by the snowboarder).

The background (trees, sky, ground) is stable with no uniform shifting, and there is no fluid motion (fire, water, smoke) or strong wind effects. The environment is snowy, but the motion is not driven by ambient conditions.


A person wearing a white shirt and gray pants bends forward near a floral-patterned couch with a red pillow, then straightens up, shifts the red pillow on the couch, steps back, and turns to face the camera. The camera remains stationary, capturing the scene from a fixed position.

A person (solid object) is moving: bending down, standing, adjusting clothing, sitting on the couch, and making facial expressions (yawning/speaking).

The background (couch, pillow, picture) is static with no shifting. No ambient environmental motion (e.g., fire, water, wind) is present.


A person with closed eyes has a makeup brush applied to their lower eyelid; the person then opens their eyes, and the brush moves to the upper eyelid for application. The camera maintains a static close-up perspective throughout.

A person (subject) is applying eyeliner with a makeup brush; the brush moves along the eyelid, and the eye blinks.

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


Two light-skinned hands adjust a colorful, textured knitted fabric with blue and purple hues laid on a wooden surface. The hands smooth and spread the fabric horizontally across the table, moving from left to right and pressing to flatten it. The camera maintains a steady top-down view throughout the sequence.

Hands manipulate a knitted fabric (pulling, folding, pointing), indicating solid objects interacting via physical forces.

The wooden table background is static and shows no shifting or environmental fluid motion (e.g., fire, water, smoke).


A person in a blue shirt and dark shorts transitions from a kneeling position to sitting upright on a concrete floor, adjusting their posture. The camera captures the action from a top-down perspective with slight movement.

A person in dark clothing is moving across the ground, exhibiting crawling or prone locomotion.

Background features a static zigzag border and concrete ground with no shifting or fluid motion (fire, water, wind).


Three individuals are on stage; a seated pianist in dark attire plays the piano, a standing woman in a black dress adjusts the piano lid and then walks away toward the background, while a vocalist in a black dress remains stationary at a music stand to the right of the piano. The camera remains static with a dark curtain backdrop.

The pianist's hands move over the keyboard during performance, and the singer's head and torso exhibit subtle body movements while performing.

The dark curtain background is static with no shifting or fluid motion. No environmental elements like fire, water, or wind are visible.


A vibrant bouquet of densely packed pink, purple, and blue flowers fills the frame, with a hand entering from the right to adjust the green stems, moving them slightly within the arrangement. The hand's motion is deliberate, shifting the stems while the bouquet remains centered. The camera maintains a close-up perspective with minimal movement, focusing on the interaction between the hand and the floral stems.

A hand (discrete object) is moving to adjust the flowers.

No shifting background (no distinct walls/ground) or ambient environmental motion (fire, water, etc.).


RAW CAPTION: Got it, let's tackle this. The video shows a football game with multiple clips. First, the main subject is players in a huddle or play. Let's break down each frame.

Frame 0: Players in dark uniforms (maybe black and yellow?) with numbers, like 72. They're on a field, maybe near the end zone. Then frame 1: More players, some in white and teal, others in dark. Frame 2: Players in white and teal (maybe Dolphins?) blocking or tackling. Frame 3: Players in maroon and yellow (Redskins?) running, with the ball carrier. Frame 4: Players in red and white (maybe another team) tackling, maybe the ball carrier is in white and yellow.

Wait, the task is to describe chronological order. So the video starts with a play where a player in a dark uniform (back number 72) is in the center, then the action shifts to other plays. Each clip shows different teams: first maybe a pile-up, then a tackle, then a player with the ball in white uniform, then another play with maroon/yellow, then red/white.

Need to focus on motion and behavior. Let's see:

First scene: Players in dark jerseys (maybe black and white, with yellow accents?) are engaged in a play. The player with number 72 is visible from behind, arms raised, part of a group in formation.

Then next scene: Players in white and teal uniforms (like Miami Dolphins) are in a huddle or blocking, maybe a tackle.

Third scene: Players in maroon and gold (like Washington) are running, one player in white and teal is carrying the ball, maybe being tackled.

Fourth scene: Players in red and white uniforms (maybe Baltimore) are tackling a player in white and yellow.

Now, chronological order of the video's clips: the video shows multiple plays in sequence. So the first play has players in dark uniforms (like the one with 72) in a huddle, then cuts to another play with white/teal players, then maroon/gold, then red/white.

Need to describe each part in order. Also, mention appearance: number of players, colors, their actions.

For the first clip: A group of football players in dark uniforms (with yellow accents) are in a huddle near the goal line, one player with the number 72 visible from behind, arms extended. Then, the scene transitions to a play where players in white and teal uniforms are engaged in a tackle, with a player in white and teal running with the ball. Next, players in maroon and gold uniforms are involved in a play where a player in white and teal is being tackled by multiple opponents. Finally, a play features players in red and white uniforms tackling a player in white and yellow, with several players in red and white surrounding the ball carrier.

Wait, need to check the exact frames. The first frame (0.0) shows a player in black and yellow (number 72) with a team of players (dark uniforms) on the field, maybe a pile-up. Then frame 1: more players in dark and white (maybe the opposing team is white and teal), the action is a tackle. Frame 2: players in white and teal are blocking, maybe a run play. Frame 3: players in maroon and gold (Redskins) are tackling a player in white and teal. Frame 4: players in red and white (Ravens?) are tackling a player in white and yellow.

Wait, but the user said "chronological paragraph", so describe the sequence of events as they happen in the video.

Let's structure it:

The video begins with football players in dark uniforms (including one with the number 72 visible from behind) engaged in a play near the goal line. The action transitions to a tackle involving players in white and teal uniforms, with multiple players colliding. Next, players in maroon and gold uniforms are shown running with the ball, being tackled by opponents. Finally, a play features players in red and white uniforms attempting to tackle a player in white and yellow, with several players surrounding the ball carrier.

Wait, but need to be concise and focus on main subjects' motion and behavior. Let's check the rules:

a) Chronological order of motion and behavior.

b) Briefly describe appearance (color, size, number) of main subjects.

c) Spatial relationships (e.g., in front of, etc.)

d) Camera perspective and movement.

e) Minimal background.

f) Exclude text, named chars, stylistic.

So let's try:

The video shows a sequence of football plays: initially, players in dark jerseys (with yellow accents) form a huddle near the goal line, with one player's back number 72 visible. The scene then

Football players moving due to physical forces: tackling, blocking, running with the ball.

No significant background shifting (field and stands are static) and no fluid/environmental motion (like fire, water, smoke, wind).


A pair of hands holds an orange, fuzzy object above a burlap cushion, then places it near a small orange butterfly-shaped piece already on the cushion. The hands use a red pen with a white grip to trace on the orange object while holding it steady. A red pen rests to the left of the cushion and a test tube to the right. The camera maintains a static top-down view.

Hands manipulate a solid orange object (likely playdough/clay) with a red tool; the orange object is displaced and deformed by hand pressure, and the red tool is used to interact with it.

Background elements (burlap fabric, red marker, white surface) show no shifting or fluid motion; no fire, water, or wind detected.


A large herd of light brown and white cows moves across a road from left to right, walking in a compact group. Some cows have prominent horns, and they traverse the street with steady movement. The camera, positioned inside a vehicle, pans right to follow the herd as they pass, with trees and utility poles visible in the background.

A herd of cows moves consistently from left to right across the frame, with individual cows displaying discrete, solid motion due to locomotion.

No fluid or wind motion observed; trees and utility poles in the background remain relatively static relative to the camera's frame.


RAW CAPTION: Got it, let's break this down. First, the video starts indoors with a boy in a blue and white striped shirt. He's holding a pink frisbee, spinning it, then stops to show it. Then the scene cuts to outdoors: same boy, now in a grassy yard with a house, tree, and cone. He throws the frisbee. Need to focus on motion chronologically.

Main subject: boy, pink frisbee. Indoor: he moves the frisbee (spinning, then holding), then outdoors: he throws it. Background details: indoors, boxes, chair; outdoors, grass, house, cone. But keep background minimal. Camera perspective: starts with indoor shot, then cuts to outdoor. Camera movement? The transition is a cut, so no movement in the shots themselves, just a scene change.

Let's structure the caption:

First part: Indoor. Boy in blue/white stripes holds pink frisbee, spins it, stops to display. Then scene changes to outdoor: boy in grassy yard, throws pink frisbee. Mention spatial relationships? Indoors, background has boxes, chair; outdoors, house, cone.

Check rules: a) motion chronologically: indoor actions (spinning frisbee, holding), then outdoor (throwing). b) appearance: boy's shirt, frisbee color. c) spatial: indoor background elements, outdoor background elements (but minimal). d) camera: starts with indoor, cuts to outdoor. e) minimal background. f) no text, names.

So draft:

A boy in a blue and white striped shirt holds a pink frisbee indoors, spinning it and then displaying the frisbee with both hands. The scene transitions to an outdoor grassy yard where the boy throws the pink frisbee toward an orange cone near a house and trees.

Wait, check if that's concise. Let's see. The first part: holds, spins, displays. Then outdoors, throws. Background: indoor has boxes, chair (but minimal), outdoor has house, cone. The caption should be concise. Let's check the rules again.

Focus on motion and behavior, chronological. So indoor: initial action (spinning frisbee), then holding it. Then outdoor: throwing. The caption needs to mention the sequence.

Also, the output format is <caption_output>...<caption_output>

So let's write:

A boy in a blue and white striped shirt spins a pink frisbee indoors, then holds it with both hands. The scene cuts to an outdoor grassy area where the boy throws the pink frisbee toward a cone near a house.

Wait, "spins" might be better as "spins and stops to display". But "spins a pink frisbee indoors, then holds it" – but the first frame shows him holding it up, then spinning. Wait, first frame he's holding it, then moving it. The video starts with him holding the frisbee, then spins it (so motion of spinning), then stops to show it. So "spins the pink frisbee and then holds it with both hands". Then outdoors, throws.

Let's make it chronological:

The boy, wearing a blue and white striped shirt, spins a pink frisbee indoors and then holds it to display. The scene shifts to an outdoor grassy yard where the boy throws the pink frisbee toward a cone near a house.

Check if background is minimal: "indoor" and "outdoor" are enough. The specific background details (boxes, chair, house, tree, cone) are mentioned but minimally. The problem says "background descriptions minimal unless essential for understanding motion". The cone is essential for the throw direction, so "toward a cone" is okay.

Camera perspective: starts with indoor shot (no movement mentioned), then cuts to outdoor (so camera cuts). The rules say "conclude with camera perspective and movement". So the camera transitions from indoor to outdoor (cut).

Wait, the rules say: "conclude with the camera perspective and movement (e.g., top-down, pan left, slight shake)".

So in the caption, after describing the actions, mention camera. So:

A boy in a blue and white striped shirt spins a pink frisbee indoors, then holds it with both hands. The scene transitions to an outdoor grassy yard where the boy throws the pink frisbee toward an orange cone near a house. The camera cuts from an indoor setting with cardboard boxes to an outdoor view.

But need to be concise. The sample output format is a paragraph. Let's check the example in the problem: the rules say "concise, chronological paragraph".

Original video: first indoor, then outdoor. So:

The boy, wearing a blue and white striped shirt, spins and holds a pink frisbee indoors before moving outside to throw it

Person in striped shirt manipulates a pink frisbee through throwing/catching actions; motion is discrete and physically driven by human locomotion.

Indoor background (cardboard boxes, chair, fabric) remains static; outdoor background (grass, house, trees) shows no fluid or environmental motion (fire, water, wind). Scene transitions via cuts, not continuous background shifting.


A man in a black and white striped shirt, blue pants, and dark shoes dances with a woman in a white blouse, black skirt, and white shoes with black accents. They begin holding hands, then the woman spins, her skirt flaring, while the man pivots around her; they maintain close proximity as they rotate in a circular motion. The camera remains stationary, capturing their synchronized movements against a backdrop of green and pink walls.

Two solid objects (a man in a striped shirt and dark pants, and a woman in a white top and black skirt) are moving in synchronized dance steps, including spins, turns, and leg lifts. Their motion is discrete and explicitly driven by locomotion.

The background (green wall with decorative pattern and pink curtains) shows no shifting or environmental fluid motion; static elements remain fixed relative to the frame. No fire, water, smoke, or wind effects are present.

A person (top) manipulates a box (tilting, opening), and a hand (bottom) moves a small object on the table. These are solid objects moved by explicit physical forces (hand movements).

The background (table with blue and yellow stripes) is static; no fluid or environmental motion (fire, water, wind) observed.


RAW CAPTION: Got it, let's tackle this. First, the video shows a person using a sanding tool on a wooden window frame. Let's break down the actions step by step. The person is wearing a checkered shirt, their hand is holding a circular sander. They start sanding the wooden plank, moving the sander along the wood. Then they stop, maybe check the surface, and point at a spot. The background has a window with frosted glass and some construction elements, but we need minimal background. Camera perspective: it's close-up on the hand and wood, maybe slight movement following the action. Let's structure it chronologically.

First, the person's hand with the sander on the wood. Then moving the sander, then stopping, pointing. Mention the checkered shirt, the sander, the wood. Spatial: the hand is in front of the window frame. Background: window with glass panes, but keep it minimal. Camera: close-up, follows the hand movement.

Now, write concise paragraph. Make sure to mention motion order. "A person in a checkered shirt uses a circular sander to smooth a wooden window frame, moving the tool along the wood's surface; they then pause, stop sanding, and point to a specific spot on the plank. The camera maintains a close-up view focused on the hand and wood, slightly shifting to follow the motion." Wait, but need to check rules. Rules say chronological, motion of main subjects. Main subject is the person's hand. So:

"A person wearing a checkered shirt sands a wooden window frame with a circular sander, moving the tool horizontally across the wood; they then cease sanding, lift the sander, and point at a section of the plank. The camera stays close to the action, tracking the hand's movements against the window frame's backdrop."

Wait, check the frames: the first frames show the hand sanding, then moving the sander, then stopping, pointing. So sequence: sanding → moving the sander → pausing, pointing.

Also, the person's hand, checkered shirt, the sander (circular), wood. Background has window panes but minimal. Camera perspective: close-up, maybe slight movement. Let's make sure to mention spatial: the hand is working on the wooden frame which has glass panes above.

Wait, the video shows the hand on the wooden plank below the window. So the wooden frame is part of the window structure, with glass panes above. So the hand is in front of the window frame.

Putting it all together:

"A person in a checkered shirt uses a circular sander to smooth a wooden window frame, moving the tool across the plank's surface; they then stop sanding, lift the sander, and point to a spot on the wood. The camera remains close to the hand and frame, following the motion."

Check rules: chronological, motion behavior. Yes. Appearance: checkered shirt, circular sander. Spatial: hand on frame, frame has glass panes. Background minimal. Camera: close-up, following motion.

Another version: "A person wearing a checkered shirt sands a wooden window frame with a circular sander, moving it horizontally along the wood; they pause, remove the sander, and point to a section of the plank. The camera maintains a close-up view focused on the hand and frame."

Wait, in the frames, after sanding, the hand stops, then points. So sequence: sanding → stopping → pointing. Also, the sander is moved, then lifted, then pointing.

Let's check the video frames:

0.0 - 3.0: sanding motion (hand moving sander along wood)

3.0 - 4.0: stops sanding, hand lifts sander

4.0 - 5.0: points to a spot on the wood.

So yes, the order is sanding, then stopping, then pointing.

So caption should be: A person in a checkered shirt uses a circular sander to smooth a wooden window frame, moving the tool along the wood's surface; they then stop sanding, lift the sander, and point to a specific spot on the plank. The camera stays close to the action, tracking the hand's movements.

Check for conciseness. "A person wearing a checkered shirt sands a wooden window frame with a circular sander, moving it horizontally; they then cease sanding, lift the tool, and point at a section of the wood. The camera maintains a close-up view, following the hand's actions."

Yes, that's concise. Avoid excess. Make sure to mention the motion order.
</think>

<caption_output>A person wearing a checkered shirt uses a circular sander to smooth a wooden window frame, moving the tool horizontally across the wood's surface; they then stop sanding,

A person's hand (discrete solid object) moves along the wooden beam, performing actions like touching and inspecting the wood surface. The hand's motion is deliberate and physically driven by human action.

The window panes and structural elements in the background are static with no signs of shifting, fluid motion (water, smoke), or wind-driven movement. No ambient environmental elements dominate the scene.
