A person in a green shirt and black apron holds a knife and places a large green watermelon onto a green cutting board. They adjust the watermelon, turn to face the camera, and then move the watermelon to a white cutting board beside the green one. The camera starts with a close-up of the person’s back and shifts to a wider angle showing the watermelon’s relocation.

A person (wearing a green shirt and apron) is moving their hands and a knife to cut a watermelon on a green cutting board. The watermelon and knife exhibit discrete, solid object motion due to physical forces (cutting).

The tiled wall and counter elements remain stable throughout the video, showing no shifting or fluid motion (e.g., water, smoke, wind).


RAW CAPTION: Got it, let's tackle this. First, the video starts with a person on a grassy coastal area. The person is preparing, maybe for kite surfing. Then they jump into the air—wait, the second frame shows them mid-air. Then they're on a board, gliding over water. The kite is visible, so it's kite surfing. The person is silhouetted against the sky, then they land on the water, creating a splash. Let's check the frames: 0.0: person on grassy land, 1.4: jumping, 2.5: airborne on board, 3.6: over water with kite, 4.7: landing.

Main subject: one person, kite, board. Motion: starts on land, jumps, soars above water, then lands. Appearance: person is dark (maybe wetsuit), kite is colorful (in frame 4.7 it's greenish), board is light. Spatial: grassy area to water. Background: ocean, sky with clouds, but minimal description. Camera perspective: probably follows the person's movement, maybe some camera shake.

Need to be chronological. Start with the person on the grass, then jumps (leaping into the air), then the person is airborne with the kite, then skimming over water, then lands on the water. Describe the number (one person), appearance (dark clothing, board, kite). Spatial: from grassy cliff to water.

Check rules: focus on motion, chronological. So: A single person in dark attire leaps from a grassy coastal cliff, soaring through the air while controlling a kite, then skims across the water's surface before landing with a splash. The camera follows the subject’s movement, capturing the action from a slightly shaky perspective.

Wait, need to make sure it's concise. Let's see:

0.0: person on grassy area, 1.4: jumping (leaps into the air), 2.5: airborne (on board, kite), 3.6: over water, 4.7: landing on water.

So:

A person in dark clothing jumps from a grassy coastal edge, soaring above the water while holding a kite, then lands on the water's surface with a splash. The camera tracks the subject's motion, following their trajectory from land to water.

Check if spatial relationships are relevant: "from grassy coastal edge" — that's the start. Then "soaring above the water" — spatial. Then "lands on the water's surface".

Appearance: "dark clothing" — yes, since they're silhouetted but in later frames, maybe dark wetsuit. Kite: in frame 4.7, it's greenish, but maybe just "kite" without color? The rule says "briefly describe appearance", so if color is visible, mention. In frame 4.7, the kite is light blue/green, but maybe just "kite".

Wait, the problem says "briefly describe their appearance and number (color, size, orientation)". So the person: dark (color), single (number). Kite: color maybe, but in frame 4.7 it's visible as a light-colored kite (since it's 4.7 frame, which shows the kite). But maybe the caption doesn't need to specify color, but the rule says "if relevant". Hmm.

Alternative:

A single person in dark attire leaps from a grassy coastal area, ascending into the air while maneuvering a kite, then glides over the water's surface before landing with a splash. The camera follows the subject's movement, capturing the transition from land to water with slight motion.

Wait, need to check if the first frame is person on grassy area. Then second frame: jumps (leaps into the air), so "leaps into the air" is accurate. Third frame: airborne, holding kite, on board. Fourth frame: over water, kite visible. Fifth frame: landing on water.

So chronological: starts on grass, leaps, soars, skims over water, lands.

So:

A person in dark clothing jumps from a grassy coastal cliff, soars through the air while controlling a kite, skims across the water's surface, then lands with a splash. The camera follows the subject's motion from a slightly shaky perspective.

Check all rules:

a) Motion and behavior chronological: yes.

b) Appearance: dark clothing, single person, kite.

c) Spatial: grassy cliff to water.

d) Camera: follows motion, slightly shaky.

e) Background minimal: only "coastal cliff" and "water's surface", which is essential for motion.

f) Exclude text, names: yes.

So the caption should be concise, like:

A person in dark clothing jumps from a

A person (kite surfer) and a kite are moving; the surfer is propelled by the kite.

The background (grassy shore and distant horizon) shifts uniformly, indicating camera panning. Water movement is ambient but not dominant.


A shirtless boy in gray shorts and a boy in a red shirt with gray shorts run toward a red playground slide; the red-shirted boy climbs the slide, slides down, and exits the structure, while the camera follows their movement with a slight shake.

Two children (one in red shirt, one in pink shirt) move: the child in red interacts with the slide (climbing, sliding down), while the other child runs and appears to fall near the slide base.

Static playground structures (blue poles, red slide) remain fixed with no significant background shifts or fluid/environmental motion (e.g., water, wind, smoke).


A person with long dark hair moves their light-skinned hands in front of their face, initially interlocking fingers and clapping motions, then separating the hands with one moving upward while the other lowers, and finally raising both hands to display thumbs-up gestures. The camera remains static, capturing the actions against a room background with minimal furniture visible.

Discrete person (long hair) making hand gestures and head movements; motion tracked via deliberate limb actions.

Background elements (lamp, furniture, poster) remain static with no shifting or fluid motion. No fire, water, smoke, or wind present.


A black tool moves across a red paint smear with yellow and white edges, pressing into the paint to form circular indentations. The tool continues to create multiple circles within the red paint, which spreads across a light background. The camera remains top-down and stationary throughout.

A paintbrush (solid object) is moving across the surface, spreading red paint. The brush is the only discrete solid object visible in motion.

The background (gray surface) is static with no uniform shifting. The motion of the paint is caused by the brush, which is not a natural fluid motion (fire, water, smoke, wind) but a human-induced action.


A gloved hand (blue) applies a glossy substance to the upper back of a person wearing a pink top. The hand spreads the substance in a circular motion across the skin, moving from the center outward. The person lies prone on a white surface, with a dark edge visible to the left. The camera maintains a close-up, static perspective focused on the application area.

A gloved hand is moving to press and rub a mark on the thigh; the thigh is minimally displaced due to the pressure.

No shifting background elements; no fire, water, smoke, or wind detected.


A man wearing a green shirt with a circular logo and a black beanie stands with his back to the camera, raising and lowering his arms in front of him. To his left, a young girl in a light-colored top stands still, while to his right, a boy with light hair also remains stationary, both observing the man. The scene takes place in a sunlit forest with trees and grass in the background, and a fallen log lies near the ground. The camera remains stationary, capturing the subjects from behind the man.

The man gestures with his arms (pointing and raising), turns slightly, and shifts position; children move partially into frame (e.g., the child on the right shifts position). All movements are discrete and attributable to human locomotion/gestures.

No fire, water, or smoke visible. Trees and hills are stationary; minimal background movement (if any) is likely due to wind but not dominant, as the background elements do not shift uniformly.


A person wearing blue gloves uses a white cloth to rub a stack of light and dark wooden blocks, moving the cloth in a smoothing motion across the surface. The round black clock with white face remains stationary to the left of the blocks. The camera maintains a top-down view with minimal movement.

A person wearing blue gloves is moving a white cloth to wipe wooden blocks, with hands and cloth exhibiting discrete motion due to physical contact.

Static background elements (wall, clock, wooden blocks) show no uniform shifting or environmental motion (fire, water, smoke, wind).


A hand picks up a blue and silver pencil sharpener from a dark surface with a logo, holds it above the surface, and inserts a yellow pencil into the sharpener. The camera remains in a close-up top-down perspective throughout.

A human hand manipulates a small solid object (metal/plastic component), lifting, rotating, and positioning it to display details. The hand's motion is explicit physical interaction.

The background features a static logo ('KU since 1919') with no shifting elements or fluid/environmental motion (e.g., fire, water, smoke).


Three individuals in black uniforms with gold sashes and tall feathered hats walk forward in a straight line through a hallway, maintaining synchronized movement. They proceed with white-gloved hands at their sides before simultaneously raising their arms to their foreheads in a salute. The camera remains steady, capturing their coordinated motion from a frontal perspective as they advance toward the viewer.

Three marching band members are moving: they march in place and perform synchronized salutes. Their movements are distinct and solid, representing explicit physical locomotion and actions.

The background consists of a stationary hallway with walls and distant people. There is no shifting background (e.g., no panning or tilting of the camera) and no fluid/environmental motion (fire, water, smoke, wind).


A person in a pink shirt and gray pants walks toward a stroller, extending their arm as a child in the stroller reaches out. The person bends down to embrace the child, leaning closely together. The camera captures the interaction from a low angle with slight movement.

Two children are moving: one child in a purple shirt walks toward the camera, and another child (partially visible in blue) extends their arms to interact with the first child.

The background elements (buildings, bushes) remain static across frames with no uniform shifting, and there are no fluid/environmental motions (fire, water, wind) present.


A person wearing blue gloves uses their right hand to guide a scalpel across a patient's skin while the left hand holds a circular probe to stabilize the area; the scalpel moves in a precise, downward motion as it incises the skin, with the probe positioned to the left of the scalpel; the camera maintains a static close-up view focused on the hands and skin interaction.

Discrete solid objects (blue-gloved hands, medical tool) exhibit controlled motion during a precise procedure on a patient's leg.

Background elements (e.g., light blue scrubs, pillow) show no uniform shifting; no fire, water, smoke, or wind present.


A person in a red shirt sits at a desk with a white writing surface. Close-up shots show hands using a brush pen to write "Calligraphy" in flowing strokes, with blue tape securing the paper. The hands then switch to a fine brush, applying blue ink to create curved strokes on the paper. The camera shifts from a medium shot to top-down close-ups, focusing on the fluid motion of the brushes and the evolving letterforms.

Discrete objects: the person's hand and pen moving to write calligraphy on whiteboard and paper; motion is controlled and directional with no collisions or complex physics.

No shifting backgrounds or fluid/environmental motion observed; whiteboard and table remain static throughout the video with no visible fire, water, smoke, or wind.


A person with long dark hair and dark clothing enters the frame from the right, moving toward the center to play a wooden flute. They hold the flute horizontally, positioning it to their lips as they play, with a snowy forest visible through a large window behind them. The camera remains stationary, capturing the individual in profile against the window.

A seated person playing a flute; discrete motion observed in finger movements on the flute and slight head adjustments while playing.

The background shows a static forest scene through a window with no significant fluid or environmental motion (e.g., wind, water); trees and ground appear motionless with no fire or smoke.


A hand holding metal tongs stirs browned food pieces in a black frying pan with bubbling liquid. The tongs grasp and lift pieces, flipping them within the pan while the hand moves them continuously. The camera remains stationary in a close-up perspective focused on the pan's contents.

A hand holding tongs manipulates pieces of food (chicken) in a frying pan. The tongs move the food pieces via direct physical contact, showing discrete object-to-object interaction.

The kitchen background (stove, pan, and surrounding elements) is static with no uniform shifting. The only ambient elements are minor oil bubbling from cooking, which is not dominant.


A small child wearing a red and white checkered shirt, dark pants, and a white hat walks across a green numbered court, using a stick to move a disc. The child moves from the right side of the frame toward the left, stepping onto marked sections of the court while adjusting the disc's position. The camera follows the child's motion with a slight pan left to maintain focus on their actions, capturing their progression along the court's surface. Background elements include a chain-link fence and greenery, but the scene centers on the child's movement and interaction with the court.

A child (discrete solid object) moves across the court, interacting with a disc (another discrete object) through locomotion and physical contact.

Background elements (fence, trees, ground) show no uniform shifting or fluid motion; no fire, water, or smoke observed.


A person wearing a dark shirt holds a silver and black clarinet, initially positioned vertically with hands gripping the instrument's body. They rotate the clarinet slightly, adjust finger placement on the keys, and bring the instrument closer to their mouth. The individual stands in front of a light blue wall with framed pictures. The camera maintains a low-angle perspective, remaining static throughout the sequence.

The person is manipulating the clarinet, moving it in their hands and bringing it to their mouth.

No shifting background or fluid/environmental motion detected.


A woman with long dark hair wearing a black top massages a shirtless person lying face down on a purple mat with a white sheet; she moves her hands in a rubbing motion on the recipient’s back, which remains still. The recipient is positioned beneath the masseuse, who leans forward to apply pressure. The camera starts close-up on the interaction, then pans slightly to the right to reveal more of the room, including green curtains and a teal chair in the background.

The massage therapist's hands and arms move actively over the client's back and shoulders, applying pressure in a controlled manner. The client remains stationary on the massage table.

The background (green curtain, chair, carpeted floor) remains stable with no shifting or environmental motion. No fire, water, smoke, or wind is visible.


tags. Keep it concise, chronological. Start with the person holding the gun, then the spraying action. Conclude with camera perspective—close-up, static. Minimal background.  Possible draft: A person wearing orange gloves and pink overalls holds a spraying gun, angling it to apply a steady stream of water onto a dark surface. The hand moves the gun smoothly across the surface, creating a uniform spray pattern. The camera maintains a close-up, static view focusing on the spraying action and the water droplets hitting the surface.  Check if I missed anything. Need to mention the motion (spraying, moving the gun), appearance (gloves, overalls), spatial (person on right, spraying left), camera (static, close-up). Exclude text, names. Okay, that should cover it. </think>  <caption_output>A person wearing orange gloves and pink overalls holds an angled spraying gun, moving it steadily to apply a fine stream of water onto a dark surface. The hand guides the gun in smooth, controlled motions, creating a consistent spray pattern across the target area. The camera maintains a close-up, static perspective focusing on the spraying action and the water droplets contacting the surface.

A person's arm and a sprayer gun are moving in a controlled manner to apply the spray to the wall, which is a discrete solid object motion.

The background (a dark wall) is static and shows no uniform shifting. The spray is a transient fluid motion but not dominant; the primary motion is the person's arm movement.


RAW CAPTION: Got it, let's break this down. The video shows three people in yellow shirts in an indoor gym. First, look at the sequence. At the start, a girl in yellow stands near a yellow ball on the floor. Then, in the next frames, another girl in yellow runs towards the ball. Wait, the first frame: main subject is the girl with the glove, then in frame 2, she's still there, but the other two move. Let's check each frame.

Frame 0: Three people—center is a girl in yellow (shorts, glove), ball on floor. Two others in yellow: one left, one right.

Frame 1: The left girl runs left, the right girl (maybe) moves towards the ball? Wait, no. The video has a sequence where the first person (front) stands, then the person on the left runs to the left (maybe to get the ball), and the person on the right is near the ball. Wait, frame 0: ball is in front of the center girl. Then frame 1: the center girl is still there, but the left girl is moving. Wait, let's track motion.

Chronological order: The center person (yellow shirt, black shorts, glove) is standing. Then, the person on the left (yellow shirt) runs towards the left, possibly to get the ball. Wait, no—maybe the ball is rolled? Wait, the ball is on the floor in front of the center person. Then, in frame 2, the left person is running left, the center person is still standing, and the right person (yellow shirt) runs towards the center's position? Wait, maybe the left person runs to the left, then the center person moves towards the right, and the right person moves towards the ball.

Wait, let's list actions:

- Initial: Three people in yellow shirts in gym. Center person (yellow, black shorts, glove) stands near yellow ball on floor.

- Then, the person on the left (yellow shirt) runs towards the left side of the frame.

- The person on the right (yellow shirt) runs towards the center area.

- The center person remains stationary for a bit, then maybe moves slightly.

Wait, the video starts with the center girl, then the left girl runs left, right girl runs towards center, and center girl stays. Let's check the frames.

[0.0] Frame: Center girl (yellow, black shorts, glove) stands, ball on floor. Two others: left girl (yellow) in a stance, right girl (yellow) near back.

[0.3] Frame: Left girl runs left, right girl runs towards ball (which is near center).

Wait, no. Let's see the movement. From frame 0 to 1: the left girl moves left, the right girl moves towards the center. The center girl is still there. Then frame 2: left girl continues left, center girl might move towards the ball.

Wait, but need to capture chronological order. So first, the three people are in the gym. The central figure (yellow, black shorts, glove) is near a yellow ball. Then, the person on the left (yellow shirt) runs to the left, the person on the right (yellow shirt) runs towards the central area, and the central figure remains stationary. Wait, but maybe the central figure moves? Let's check the frames.

Wait, the video shows:

- Frame 0: three people. Center person (yellow, black shorts) stands with glove, ball on floor.

- Frame 1: Left person runs left, center person stays, right person moves towards ball.

- Frame 2: Left person continues left, right person is near ball, center person steps forward.

- Frame 3: Left person is far left, center person moves towards ball, right person is near ball.

- Frame 4: Center person near ball, right person moves back, left person is out of frame.

Wait, but the user provided the frames as [0.0], [0.3], [0.6], [0.9], [1.2], [1.5], [1.8], [2.1], [2.4], [2.7], [3.0], [3.3], [3.6], [3.9], [4.2], [4.5], [4.8].

But the task is to write a concise paragraph. Let's see the main actions.

The video starts with a female in a yellow shirt and black shorts standing near a yellow ball on the gym floor. Two other females in yellow shirts are positioned in the background. The left female runs toward the left side of the frame, the right female runs toward the ball, and the central female takes a step forward. The camera

Two people in yellow shirts are walking; the foreground person moves slowly across the gym floor, and a background person is also moving. A yellow ball is stationary on the floor.

The background (walls, banners, gym equipment) is static and does not shift. No fluid motion (fire, water, smoke, wind) is observed.


A man in a vibrant, multicolored traditional outfit performs a high kick toward a boy in a black vest and white shirt, who steps back as the man moves slightly left. The bride in a white gown stands behind them, clapping, while other guests—including a woman in a white dress with a black belt—clap and move into view from the left. A drummer in colorful attire plays near the right background. The camera maintains a static perspective throughout the sequence.

Discrete solid objects (people) are moving: the bride and groom dance, guests enter the dance floor, and participants engage in social locomotion (e.g., walking, turning).

Static indoor background elements (walls, windows, furniture) show no uniform shifting; no fire, water, smoke, or wind visible. Ambient environmental motion is absent.


A person wearing shorts and a striped shirt moves forward toward the camera in a room with yellow walls, bending down while the camera maintains a stationary low-angle perspective, capturing their legs and lower body.

A person (visible from waist down) exhibits discrete physical movement: standing still initially, then bending down and crouching while holding an object.

The background (yellow wall, bed, wooden chair) remains static with no shifting or fluid motion. No fire, water, smoke, or wind is observed.


RAW CAPTION: Got it, let's tackle this. First, the video starts with a close-up of hands on a mossy tree trunk. A person in a black jacket with a logo is holding a piece of mossy bark. Then, the camera pulls back to show two people: one with gray hair, also in a black jacket, assisting. The man with gray hair is standing to the left of the tree, while the other person (maybe a bit older) is handling the bark. They move slightly, and the background has houses and a yard. Need to describe the motion chronologically.

First frame: close-up on hands, then pan back to show both people. The main subject is the person holding the mossy bark, then the second person joins. The background is a residential area with houses, but keep it minimal. Spatial relationships: the second person is to the left of the tree. Camera starts close-up, then pulls back to a wider shot.

Check rules: focus on motion, appearance (black jackets, gray hair), spatial (left side), background minimal. Conclude with camera perspective: starts close, then pans back to wider.

Let me structure:

A person in a black jacket holds moss-covered bark from a tree trunk. Another individual with gray hair, also in a black jacket, stands to the left, assisting. The camera zooms out from a close-up of the hands to reveal both figures near the tree, with residential houses visible in the background. The individuals interact with the bark, adjusting their grip, while the camera remains steady in a medium shot.

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

- Chronological: starts with close-up of hands, then camera pulls back to show two people.

- Main subjects: two people, black jackets, one with gray hair.

- Motion: hands holding bark, then camera zooms out to show both.

- Spatial: second person to left of tree.

- Background: residential (houses, yard) but minimal.

- Camera: starts close, then pulls back (zoom out) to wider shot.

Draft: A person in a black jacket holds mossy bark from a tree trunk while another individual with gray hair, also in a black jacket, assists from the left. The camera pulls back from a close-up of the hands to reveal both standing near the tree in a residential yard. The individuals adjust their grip on the bark as the camera stabilizes in a medium shot.

Check rules:

a) Motion: holding, assisting, adjusting grip. Chronological: starts with holding, then camera moves to show both.

b) Appearance: black jackets, gray hair.

c) Spatial: second person to left.

d) Camera: pulls back (zoom out), stabilizes medium shot.

e) Background: residential yard (minimal, as per rule e).

f) Exclude text, named characters. Good.

Yes, that's concise. Let's make it tighter.

Final draft: A person in a black jacket holds moss-covered bark from a tree trunk while another individual with gray hair, also in a black jacket, stands to the left and assists. The camera zooms out from a close-up of the hands to show both near the tree in a residential setting. They adjust their grip on the bark as the camera stabilizes in a medium shot.

Check length: keep it brief. Maybe "A person in a black jacket holds mossy bark from a tree trunk; another individual with gray hair, also in a black jacket, stands to the left and assists. The camera zooms out to reveal both near the tree in a residential yard, then stabilizes in a medium shot as they adjust their grip."

Wait, the problem says "concise, chronological paragraph". Let's ensure it's chronological:

1. Close-up: hands holding bark (first frame).

2. Camera pulls back to show both people.

3. They interact with the bark, adjusting grip.

So:

A person in a black jacket holds a piece of moss-covered bark from a tree trunk. The camera pulls back to show a second individual with gray hair, also in a black jacket, standing to the left and assisting. Both adjust their grip on the bark as the camera stabilizes in a medium shot.

That's good. Check if "residential yard" is necessary? Rule e says minimal background. The background includes houses and yard, so maybe "residential yard" is acceptable but minimal. Alternatively, "residential area" but the video shows houses and yard, so maybe just "residential background" but keep it minimal.

Original video: background has houses, grass, maybe a car. So "residential setting" is okay.

Let me check the example. The rules say "mention spatial relationships if relevant", so "to the left" is relevant.

Putting it all:

<caption_output>A person in a black jacket holds mossy bark from a tree trunk. A second individual with gray hair, also

Two individuals are engaged in handling a tree branch covered in moss; their hands move to interact with the branch, demonstrating deliberate physical actions.

The background elements (trees, houses, and vehicles) remain stationary relative to the frame, with no significant fluid motion (fire, water, smoke) or wind effects observed.


A person in a white t-shirt and gold chain turns slightly while standing beside another individual in a red shirt and beige shorts. The person picks up a red cup from the floor, bends down, then stands upright holding it. The red-shirted individual remains in the background. The camera, handheld and slightly shaky, follows the main subject’s movements through an indoor setting with minimal background details.

People in the scene exhibit movement: a person in a white shirt with gold chains shifts position (e.g., turning, gesturing), while other individuals (in red and dark clothing) remain relatively stationary or move minimally within the frame.

No shifting backgrounds or fluid/environmental motion (fire, water, wind) observed; static elements like walls, furniture, and a red bucket remain consistent across frames.


Two light-skinned hands manipulate a small, metallic object, pulling it from a package held in front of a printed shirt. The hands adjust the object, displaying it briefly. Camera remains close, with slight handheld movement.

Hands and a small pencil-like object are being manipulated; precise movements include twisting, holding, and positioning the object, showing clear physical interaction.

Background is static fabric with printed text; no fluid/environmental motion (fire, water, smoke, wind) detected. No significant shifting of background elements.


A person’s hand uses a metal chisel to carve a light-colored rectangular wooden block clamped in a vise, generating thin wood shavings that accumulate on the vise surface. The hand moves steadily along the block’s edge, then withdraws, leaving the block partially shaped with visible shavings. The camera maintains a close-up perspective, slightly panning left as the hand shifts, with a blurred workshop background featuring a chair and table.

The hand holding the chisel moves in controlled carving motions, the chisel itself advances into the wood block, and wood shavings fall away from the carving site as discrete solid objects.

The wooden stool and tiled floor background elements remain static with no uniform shifting. No fire, water, smoke, or wind is present, so no ambient environmental motion is observed.


A man in a silver suit and white hat stands on a white box, holding a string attached to a child in pink pants. The child moves toward the man, raising their arms, while another child in green pants joins, running behind the first child. Both children circle the box, with the man gesturing outward. The camera remains stationary with slight motion, capturing the scene in an outdoor urban environment with minimal background details.

Two children (a girl in pink and a boy in green) are moving: the girl reaches up to the statue, jumps, and moves her arms; the boy moves around her. The statue is stationary.

The background (building and ground) is static with no shifting. No environmental motions (fire, water, smoke, wind) are present.


A child in a blue shirt and red shorts jumps onto a bed with patterned sheets, then moves alongside a second child in a striped shirt. Both interact on the bed, with the blue-shirted child shifting positions and standing up while the striped-shirted child remains seated. The camera follows their movements with a slight shake, maintaining a close perspective on the action.

Two people: one in blue shirt and jeans moves actively on the bed, interacting with blankets and the other person who is lying under a blanket. The motion includes bending, lying down, sitting up, and moving around the bed.

The background (walls and furniture) remains stationary without uniform shifting. No environmental fluids (fire, water, smoke) are present.


RAW CAPTION: Got it, let's tackle this. First, the video starts with a split screen, but then cuts to a pool scene. The main subject is a person in a white shirt and jeans standing on the pool's edge. They raise their arms, then jump into the pool. Another person in a red top and dark shorts runs along the pool's edge. Wait, the first frame is a split screen with a white structure on the left and the pool on the right? Wait, no, the user provided the video frames. Let's check:

First frame [0.0] shows a split screen: left is a white structure (maybe a fence or something), right is a blue sky with a building. Then [1.4] shows a pool scene: clear blue water, a person standing on the edge. The person is wearing white shirt and jeans, raises arms, jumps. Then another person in red runs by. Then the person jumps in, creating a splash.

So chronological order: Start with a split screen (maybe not part of the main action), then focus on the pool. The main subject is a man in white shirt and jeans (standing on pool edge), jumps in. Then a woman in red top runs past. Wait, the video has frames:

0.0: split screen (left: white structure, right: blue sky with building, maybe a pool? Wait, no, the first frame description is [0.0] shows a split screen: left is a white structure (maybe a fence), right is a blue sky with a building. But the next frame [1.4] is a full pool scene. So maybe the split screen is just the start, but the main action is the pool scene.

So from frame 1.4 onwards: The video shows a backyard pool. A person (male, white shirt, jeans) stands at the edge, raises arms, then jumps into the pool. Meanwhile, another person (female, red top, dark shorts) runs along the pool's edge. The background has a house, trees, power lines. Camera is stationary, probably a fixed shot, capturing the pool area from a side angle.

Now, following the rules: focus on motion and behavior chronologically. Start with the person on the edge, raises arms, jumps. Then the other person runs. Need to mention their appearance briefly (color, size, orientation). Spatial relationships: the jumper is on the pool's edge; the runner is on the edge near the house. Background minimal. Camera perspective: stationary, side view.

Wait, the first frame is a split screen, but the task says "the provided video"—the video has multiple frames, so maybe the split screen is the start, but the main action starts at 1.4. So in the caption, we can start from the pool scene.

Let's structure:

The video opens with a split-screen view, then focuses on a backyard pool. A man in a white shirt and jeans stands at the pool's edge, raises his arms, and jumps into the water. As he jumps, a woman in a red top and dark shorts runs along the pool's edge. The background includes a house, trees, and power lines. The camera remains stationary, capturing the scene from a side perspective.

Wait, need to check if the first frame is part of the video. The user says "the provided video", which includes those frames. So maybe the split screen is the first part, then the pool scene. But the caption should describe the main action. The task says "chronological paragraph describing the provided video". So the video starts with split screen (maybe not important), then transitions to pool scene.

But rule e: minimal background. So maybe skip split screen as it's just part of the video but not main action.

Wait, the first frame is <0.3 seconds> which is the split screen, then <1.4> is pool. So the video's main content is the pool scene.

So:

A man in a white shirt and jeans stands on the edge of a backyard pool, raises his arms, and jumps into the water. Concurrently, a woman in a red top and dark shorts runs along the pool's edge. The camera remains stationary, capturing the action from a side angle with minimal background details visible.

Check rules: focus on motion (jump, run), appearance (white shirt, red top), spatial (jumper on edge, runner on edge), camera stationary. Background minimal.

Wait, the first frame is split screen—do we need to mention it? The task says "describe the provided video", which includes all frames. But the split screen is just a frame, maybe not relevant. The main action is the pool scene.

Another point: the split screen might be a transition, but the user's input shows the first frame as split screen, then the next frames are pool. So in the

A person throws a ball (discrete object) which follows a projectile trajectory and then a person walks by the pool (discrete object) in the scene. Both motions are due to explicit physical forces (throwing and walking).

The background elements (buildings, trees, power lines) are static and show no uniform shifting. The pool water is calm and not exhibiting fluid motion. There is no fire, smoke, or significant wind movement observed.


A person's hands manipulate thin wooden sticks over a purple cloth with scattered white powder, arranging the sticks while brushing the powder with a tool; the cloth rests on a textured surface with additional sticks nearby and a drill visible in the background. The camera maintains a static top-down view throughout.

Hands and a purple cloth with scattered white particles are actively manipulated; the hands move the cloth and tools in deliberate motions.

Background elements (table, wooden structure, pencils) remain stationary across frames; no fluid/environmental motion (fire, water, smoke, wind) observed.


A person with dark hair and a white top lifts their arms to brush and adjust their hair in a bathroom. They then use a purple curling iron to curl sections of their hair, wrapping strands around the iron near their head. The background shows a shower curtain and tiled walls. The camera stays in a close-up, fixed position during the styling process.

A person (discrete solid object) manipulates their hair using hands and a flat iron; the hair moves due to deliberate physical force application.

No ambient environmental motion (fire, water, smoke, wind) observed. Background elements (towel rack, wall, outlet) are static and do not shift uniformly across the frame.


A man in a black shirt and blue shorts gestures with his right hand toward a large circular bell-shaped object featuring stars, stripes, and a central bell image. He shifts position, moving to the left of the object, then steps back, briefly turning away. The camera pans slightly to the right and shifts perspective, capturing the man's movements around the object against a stone wall backdrop.

A person (discrete solid object) moves across the frame, demonstrating locomotion (walking/position shifting) with clear bounding box movement.

Background elements (wall, structural elements) show no uniform shifting or fluid motion (e.g., fire, water, smoke). No environmental elements exhibit dominant fluid behavior.


Two fencers in white uniforms and black helmets engage in a bout on a blue gym floor, advancing toward each other from opposite sides of a central wooden table with equipment. They lunge and deflect dynamically, shifting positions as a woman in black attire stands between them, observing. The camera remains stationary, capturing the sequence from a fixed perspective.

Two fencers (solid objects) are actively moving: lunging, parrying, and dodging during a fencing match; a referee observes and gestures.

Background elements (wooden panels, blue flooring) remain static across frames; no fluid motion (fire, water, smoke) or wind effects are present.


RAW CAPTION: Got it, let's tackle this captioning task. First, I need to parse the video frames.

Frame 0: Shows a group of people outdoors, likely a historical reenactment. A person in a white t-shirt and light shorts holds something (maybe a cup or bowl), standing in front. To the left, a person raises their arm, possibly signaling. Others in period clothing (hats, vests, coats) are around, some holding staffs. Background has tents and grass.

Frame 1: Similar to frame 0, slight movement. The person in white t-shirt still holds the item, others remain in positions. Background tents and grass visible.

Frame 2: Camera shifts to a group of people standing in a line. A person in a red shirt and hat is on the left, then others in various colors (yellow vest, blue shirt with hat, gray shirt). They're looking up, maybe watching something. Background has trees and tents.

Frame 3: Same group as frame 2, similar posture. The person in red shirt is still there, others attentive.

Frame 4: Same as frame 3, minor movement. People still observing.

Frame 5: Same group, no significant motion.

Now, chronological order. First part (frames 0-1): A crowd of people, some in historical attire, with one in white t-shirt and shorts holding an object. A person raises arm left. Then camera pans to show another group (frames 2-5) standing in line, looking up.

Main subjects: people in period clothing (various colors: red, yellow vest, blue, gray), white t-shirt person. Their motion: initial frame, some movement (arm raising), then static as they observe.

Spatial relationships: In frame 0, white t-shirt person is center front, others around. In frames 2-5, the line group is standing side by side, looking up.

Camera movement: Initially showing the crowd, then panning left to the line of observers. Background: tents, grass, trees, but minimal description.

Need to be concise. Describe chronological: Start with the first scene (group, one person in white t-shirt holding something, another raising arm), then camera shifts to a line of people (including red shirt, yellow vest, etc.) watching something.

Check rules: motion and behavior in order. Number: multiple people, mention appearance (colors, attire). Spatial: positions relative to each other. Conclude camera movement (pan left).

Putting it all together:

In the opening scene, a group of people, including one in a white t-shirt and light shorts holding a small object, gather outdoors with some individuals in historical attire; one person raises their arm. The camera then pans left to show a line of onlookers—some wearing red shirts, yellow vests, and blue-gray clothing—standing side by side and looking upward.

Wait, check if all rules are met. Focus on motion: first scene has arm raising (motion), then the second group is static but observing.

Need to mention number: "multiple people" or specific numbers? The video has a crowd, so "a group" is okay.

Appearance: colors (white t-shirt, red shirt, yellow vest, blue-gray).

Spatial: in first scene, white t-shirt person is in front, others around. In second, line of people.

Camera: pans left.

Let me make it concise.

"Initially, a crowd of people, including one in a white t-shirt and light shorts holding an object, and others in historical clothing, gather outdoors with one person raising their arm. The camera then pans left to a line of onlookers—some in red shirts and yellow vests, others in blue-gray attire—standing side by side and looking upward."

Check if it's chronological. First the first group, then the pan to the line. Yes.

Is the number correct? In frame 0, there's a group, so "a crowd" is okay. Then "a line of onlookers" (multiple people).

Mention spatial: in first scene, the person with the object is in front. Then the line is side by side.

Camera movement: pans left.

Background: minimal, as per rules.

Yes. Now check if all parts are covered.

Final caption should be under <caption_output> tags.
</think>

A person in white clothing is moving by stepping and turning; a group of people is standing and conversing with minimal motion.

The background elements (trees, grass) are static with no significant fluid or wind motion. The environment is stable.


RAW CAPTION: Got it, let's break this down. First, the video shows a person in a room with students. The main subject is the person at the front. Let's check the sequence.

At [0.0], the person is standing near a table, holding something. Then [1.0], they start moving their arms, maybe gesturing. [2.0] they move towards the table? Wait, no, the description says "leaning forward" maybe. Wait, the frames: first frame, person stands with arms maybe up. Then next, moves hands. Then next, arms wide. Then next, arms up. Then a URL appears, but we have to exclude text recognition.

So main subject: one person (adult) in front of a room with students. Appearance: dark top with pink, maybe. But rules say briefly describe appearance. So "a person wearing a dark top with pink accents stands"

Chronological order: starts standing, then moves arms (gesturing), leans forward? Wait, the frames:

[0.0]: person standing, maybe holding an object.

[1.0]: person leans forward, maybe speaking.

[2.0]: person stands up straighter? Or moves.

[3.0]: arms raised.

[4.0]: arms wide.

[5.0]: URL, but ignore.

So motion: person begins standing with arms in front, then leans forward, then moves arms up, then raises arms wide.

Spatial: in front of a table with students seated. Background: white walls, tables, some bags. But keep background minimal. So maybe "in a room with students seated in front of a whiteboard and tables" but minimal.

Camera perspective: the video is from a fixed position, looking at the room. Camera movement: the description doesn't mention, so maybe "fixed camera" or "static".

Now, following rules:

a) Focus on motion of main subject (the person).

b) Briefly describe appearance: "a person wearing a dark top with pink details stands"

c) Spatial: in front of a group of seated students, near a table with objects.

d) Conclude with camera perspective: fixed position, no movement.

e) Background minimal: just mention room with tables, but keep it short.

Let's draft:

A person wearing a dark top with pink accents stands in a room with students seated in front of them. Initially positioned near a table, they lean forward, then raise their arms in a gesture, and subsequently extend their arms wide. The camera remains static, capturing the scene from a fixed position facing the front of the room.

Wait, check for chronological order: start with standing, then lean, then raise arms, then extend. Yes.

Appearance: "dark top with pink accents" - color, size (not sure, but brief), orientation (standing).

Spatial: "in front of students, near a table"

Background: minimal, so "room with tables" but not too much.

Camera: "static" (no movement mentioned).

Also, check if there are other subjects. The students are seated, but main subject is the person, so the caption should focus on their motion.

Let me check the rules again.

a) Motion of main subjects: the person's actions.

b) Appearance: color, size, orientation. So the person is standing, wearing dark top with pink.

c) Spatial: in front of students, near a table.

d) Camera: fixed position.

e) Background minimal: room with tables, white walls, but not essential. So maybe "in a classroom setting with tables and a whiteboard" but minimal.

Let's make it concise.

"A person in a dark top with pink details stands in front of seated students, initially near a table. They lean forward, then raise their arms upward and extend them wide. The camera remains static, positioned to capture the scene from the audience’s perspective."

Wait, "audience’s perspective" might not be right. The camera is looking at the person from the front, so maybe "fixed camera facing the person".

Also, check the frames: in frame 3, there's "http://" but exclude text recognition. So no mention of that.

Let me confirm the steps:

- Start: person standing, holding something? Or gesturing.

- Frame 1: person leans forward (maybe), moving arms.

- Frame 2: person stands upright with arms raised.

- Frame 3: arms raised.

- Frame 4: arms wide.

So sequence: standing, leans forward, raises arms, extends arms.

So the caption should be chronological.

"A person wearing a dark top with pink accents stands in a classroom with seated students. They lean forward, raise their arms

A person (speaker) is moving by gesturing and slight walking; audience members are mostly static.

Background (walls, ceiling, whiteboard) is stable with no fluid or environmental motion; no fire, water, smoke, or wind visible.


A young child with short dark hair and a gray shirt holds an illuminated orange candle. Initially facing right, the child turns their head left, then brings the candle close to their mouth as if blowing on it. The background features blurred glass windows with distant lights. The camera maintains a close-up, steady perspective focused on the child and the candle.

A child is holding a lit object and exhibits subtle head movements (blinking, slight head turns) as the primary discrete object motion.

Background elements (glass-like structures with lights) show no uniform shifting; no fluid/environmental motion (fire, water, smoke, wind) is present.


tags.  Also, camera perspective: first is close-up, then top-down, then wider shot. So conclude with camera movement: starts with close-up, transitions to top-down, then wider view.  Wait rule d: conclude with camera perspective and movement. So need to mention that at the end.  Let's see:  The video begins with close-up shots of multiple hands shaping dough on a wooden table, transitions to a top-down view of hands rolling dough into balls and arranging them on a baking sheet, then shows a person carrying the sheet toward an oven, followed by a wider shot of several individuals in white uniforms and hairnets gathered near the oven.  Yes, that includes camera movement.  Now check all rules:  a) Motion and behavior chronologically: shaping dough, rolling, arranging, carrying to oven, group near oven. Yes.  b) Appearance and number: multiple hands (not specified number, but "multiple"), people in white uniforms and hairnets. Size: hands, dough balls, baking sheet. Orientation: hands on table, etc.  c) Spatial relationships: hands on table, dough balls arranged on sheet, sheet carried to oven, group near oven.  d) Camera: starts close-up, transitions to top-down, then wider shot. So "begins with close-up shots, transitions to top-down view, then wider shot".  e) Background minimal: kitchen setting, but not detailed.  f) No text, no named characters.  g) No internal reasoning.  So final caption:  <caption_output>The video starts with close-up shots of multiple hands shaping dough on a wooden table, transitions to a top-down view of hands rolling dough into small balls and arranging them on a baking sheet, then shows a person carrying the sheet toward an oven, followed by a wider shot of several individuals in white uniforms and hairnets gathered near the oven.

Hands shaping dough, placing cookies on trays, and people carrying trays exhibit solid, distinct motion due to physical interactions (e.g., pressing, rolling, lifting).

No shifting backgrounds or fluid/environmental motion (e.g., fire, water, wind). The kitchen walls and static elements remain consistent; the camera movement is panning to follow subjects but does not shift the background uniformly.


A shirtless man in dark plaid shorts and a young boy in dark swim trunks stand near a metal pole on a beach. The man bends forward, guiding the boy’s hand toward the pole; the boy reaches out, then adjusts his stance while the man supports him. The camera remains stationary, capturing the interaction from a side angle with the sandy beach and ocean in the background.

Two discrete objects: a man and a child. The man is moving his arms and body to interact with the child (giving an object). The child is moving his hands and bending down. These motions are due to physical interactions.

The beach background (sand, ocean, steps) is static. The ocean waves are subtle and not dominant. There is no significant environmental fluid motion (like fire, smoke) that dominates the scene.


A group of approximately twenty people in purple and white uniforms perform synchronized movements on a basketball court, starting in a straight line and transitioning into a circular formation while facing the audience; the crowd in blue and yellow attire fills the stands surrounding the court, and the camera maintains a static top-down perspective throughout.

Basketball players (in uniforms) and the basketball exhibit distinct locomotion: dribbling, passing, running, and shooting movements. Spectators in the stands show minimal, non-continuous motion.

The arena background (bleachers, court lines, walls) remains stationary across frames with no fluid motion (fire, water, smoke) or wind effects observed. Static elements show no uniform shifting.


A gray tabby cat with distinct black stripes and yellow eyes is being gently petted by a hand on its cheek. The cat shifts its head slightly, eyes partially closed, while the hand maintains contact. The cat remains seated on a gray surface, with a blurred background of furniture. The camera stays close-up with minimal movement.

A cat is being petted by a hand, with the cat's head exhibiting slight movements due to physical interaction (petting). The hand and cat are discrete, solid objects moving in response to contact forces.

The background includes static elements like a chair and floor; no significant shifting or fluid motion (fire, water, smoke, wind) is present.


A person with brown hair and a black headband uses their fingers to gently touch and adjust the skin around their nose. The background features a lace curtain with white floral patterns. The camera remains in a close-up position, focusing on the nose and eye area, with no noticeable movement.

Discrete solid object: person's finger moving deliberately to apply substance to face (localized motion).

Background is static wall with floral pattern showing no shifting or environmental motion (fire, water, smoke, wind).


RAW CAPTION: Got it, let's tackle this. First, I need to generate a concise paragraph describing the video chronologically. Let's start by looking at the frames.

The first frame shows a knife on a wooden board. The knife has a shiny blade and a wooden handle. Then the video moves to hands using a stone. The text says to start sharpening the front side on #1000 stone. So the main subjects are the knife, the sharpening stone, and the hands.

Chronic order: First, the knife is placed on a wooden board. Then hands pick up the knife and start sharpening on the stone. The stone is part of the setup, probably a whetstone. The hands are moving the knife back and forth on the stone. The stone is #1000, but we don't need to mention the number as per the rules? Wait, no—rule f says exclude text recognition. Oh right, rule f: Exclude text recognition, named characters, or stylistic analysis. So the text "Start Sharpening..." is not to be included. So we can't refer to that text.

So focus on the motion: hands hold the knife, place it on the stone, and move it back and forth. The knife is metallic with a wooden handle. The stone is a rectangular, maybe grayish (since in frame 2, it's a stone with a wooden board? Wait frame 2: hands are placing the knife on a stone. The stone is on a wooden board, which is on a surface.

First frame: close-up of knife on wooden board. Then frame 2: hands adjusting the knife on the stone. Then frames 3-5: hands moving the knife back and forth on the stone. The stone is likely a whetstone, maybe with a grit number, but we can't mention the number. Wait, the stone is called #1000 in the text, but we have to exclude text recognition. So just describe the stone as a sharpening stone.

So the caption should be: A knife with a metallic blade and wooden handle rests on a wooden board. Hands grasp the knife, position it on a rectangular sharpening stone, and move it back and forth to sharpen the front edge. The stone sits on a wooden surface. The camera starts with a close-up of the knife, then shifts to show the hands and stone during sharpening.

Wait, need to check rules:

a) Chronological order: start with knife on board, then hands sharpening.

b) Appearance: knife (metallic blade, wooden handle), hands (white shirt sleeves, so maybe color), stone (rectangular).

c) Spatial: hands are in front of the stone, knife is on the stone.

d) Camera: first close-up, then shifts to show hands and stone.

e) Background: minimal—maybe the surface it's on.

f) Exclude text, so no mention of the text in the video.

So putting it all together:

The video opens with a close-up of a knife featuring a shiny metallic blade and wooden handle placed on a light wooden board. A person’s hands, clad in white sleeves, then adjust the knife onto a rectangular sharpening stone and move it rhythmically back and forth to sharpen the front edge. The stone remains stationary on a wooden surface as the hands guide the knife. The camera maintains a close-up view, transitioning to show the hands and stone during the sharpening motion.

Check for rules:

- Chronological: starts with knife on board, then hands sharpening.

- Appearance: knife's features, hands (white sleeves), stone.

- Spatial: knife on stone, hands moving it.

- Camera: close-up, then shows hands and stone.

- Background minimal.

- No text.

Yes, that seems good. Now make it concise. Let's tighten:

A knife with a metallic blade and wooden handle rests on a light wooden board. A person’s white-sleeved hands adjust the knife onto a rectangular sharpening stone and move it back and forth to sharpen the front edge. The stone sits on a wooden surface. The camera begins with a close-up of the knife, then focuses on the hands and stone during the sharpening motion.

Wait, maybe "the video opens with" can be simplified. Also, the first frame is the knife on board, then the hands start working. Let's make it a single paragraph.

The video starts with a close-up of a knife with a metallic blade and wooden handle placed on a light wooden board. A person’s hands, wearing white sleeves, then place the knife onto a rectangular sharpening stone and move it rhythmically back and forth to sharpen the front edge. The stone remains on a wooden surface as the hands guide the knife. The camera maintains a close-up perspective, shifting to emphasize the hands and stone during the sharpening motion.

Yes, that's concise

Hands (in white shirt) and knife are moving in controlled, back-and-forth motion against a stationary sharpening stone, demonstrating deliberate physical interaction.

No shifting background or fluid/environmental motion (fire, water, wind) detected. Background elements (wall, countertop) remain stationary throughout the sequence.

The background includes wooden cabinets, a refrigerator, and kitchen items. The camera remains static throughout.

The person is moving hands and holding objects (yellow folder, blue item), indicating discrete solid object motion.

No significant background shifting or fluid/environmental motion detected (e.g., no fire, water, wind).


Two men in black shirts and shorts play squash on an indoor court. The man on the left sprints forward with a racket, while the other steps back; they then exchange positions, moving right and left across the court. The camera maintains a stationary wide-angle view throughout, capturing their movement within the court boundaries.

Two players (solid objects) are actively moving: one player swings a racquet to hit a ball, while both players reposition and collide with the ball through locomotion and physical interaction.

The background (walls, court markings) shows no shifting or fluid motion; static elements remain consistent across frames with no signs of fire, water, smoke, or wind-driven movement.


Several children in bright yellow shirts stand on a grassy field. One child runs toward a ball on the ground, bends down to pick it up, and another child in a yellow shirt kneels nearby. Both children remain on the grass with the ball. The camera pans slightly to follow the children’s movements.

Children in yellow shirts are moving: running, bending, and interacting with balls on the grass. Their motion is driven by locomotion and physical interactions (e.g., picking up balls, sitting down).

The background features static trees and distant figures with no significant shifting or fluid motion (e.g., wind, water). No fire, smoke, or fluid effects dominate the scene.


A shirtless individual with short hair moves their right arm up to hold a white object in front of them, smiling, then lowers the arm and repeats the motion. The background features a dimly lit room with a window, and the camera remains steady in a close-up perspective.

Two shirtless individuals are moving their heads and bodies (gesturing, talking), which is discrete object motion.

The background (window, room interior) is static with no signs of fire, water, smoke, or wind. No ambient environmental motion detected.


A person in a gym, wearing a light gray shirt and dark shorts, holds two dumbbells at waist level in a squat position. They rise to a standing posture while simultaneously pressing the dumbbells overhead with extended arms, maintaining a straight stance. The gym environment includes visible weight racks and mirrors in the background. The camera remains stationary, capturing the movement from a frontal perspective.

The skier maintains a consistent forward motion, becoming increasingly visible as they approach, while the camera remains stationary, capturing the scene from a fixed perspective.

A single skier in red clothing is moving downhill along a snow-covered trail, exhibiting consistent locomotion motion typical of skiing.

The background consists of stationary trees and snow-covered terrain with no significant fluid motion (e.g., fire, water) or strong wind-induced swaying; background elements remain largely static across frames.


A woman in a black tank top and white shorts bends toward a tricolor beagle (brown, white, black) wading in shallow stream water, while a man in a green shirt and khaki pants stands to her left holding a phone. The dog steps forward, moves deeper into the water, and approaches the woman, who extends her hand. The camera remains stationary, capturing the interaction from a slightly elevated perspective.

Two human figures (adult and child) and a dog are moving: the dog wades/swims through the water, the child bends and interacts with the dog, and the adult stands observing.

The background includes stationary trees and rocky terrain with minimal movement; water shows gentle ripples but is not the dominant motion source.


Two individuals, one with blonde hair and the other with dark hair, each holding white cloths, clean a dark wooden surface from a top-down perspective. They then stand and move away, revealing a kitchen setting with cabinets. The camera focuses on the wooden surface with small spots, followed by a close-up of a hand using a white cloth. The camera transitions from top-down to close-up views with minimal movement.

Two people (with tools) and a cloth are moving. The people are working on a wooden object, and the cloth is being moved over the surface to polish or clean it. These are solid objects moving due to manual forces.

No shifting backgrounds or fluid/environmental motion (fire, water, wind) observed. Background elements (wooden structures, walls) are static across scenes. Close-up of cloth shows no fluid motion.

RAW CAPTION: Got it, let's break this down. The video starts with a woman in a red dress walking through a doorway. Then it cuts to a bathroom scene where a shirtless man with a necklace is standing in front of a mirror. A woman with long hair, also shirtless, approaches him from behind. She hugs him, and he turns to face her. They interact closely, with her leaning into him. The camera seems to follow the action, maybe a slight movement as the scene transitions. Need to focus on the motion chronologically: woman in red dress moving, then the bathroom scene with the man and woman. Describe their appearances briefly—shirtless man, long-haired woman. Spatial relationships: she approaches from behind him in the mirror. Background minimal, just the bathroom. Camera movement—probably follows the action, maybe a steady shot but maybe slight shift. Check rules: no names, no text, just actions. Let's structure it step by step.

First frame: woman in red dress (red, dress, walking through doorway). Then cuts to bathroom: shirtless man (no shirt, necklace) in mirror, long-haired woman (shirtless, back to camera) approaches him. She hugs him, he turns, they interact. Camera perspective—maybe the shot transitions from the doorway to the bathroom, so camera moves to follow the scene. Let's make it concise.

Wait, the first frame is the woman in red walking through a doorway. Then the next frame shows the man in the bathroom (shirtless, necklaces) and the woman's back (shirtless, long hair). Then she moves towards him, hugs him. So the sequence is: woman in red dress moves through doorway; then in bathroom, shirtless man stands in front of mirror, shirtless woman with long hair approaches him from behind, wraps arms around him, he turns to face her. Camera perspective: starts with a view through a doorway, then shifts to the bathroom interior, possibly a medium shot capturing their interaction.

Avoid background details. Mention appearance: man shirtless, wearing necklace; woman shirtless, long hair. Actions: woman walks through doorway, then enters bathroom, hugs man from behind, man turns. Spatial: woman approaches from behind man in mirror.

Now, condense into a paragraph.

Start: A woman in a red dress walks through a doorway. Then, in a bathroom, a shirtless man with a necklace stands before a mirror as a shirtless woman with long hair approaches him from behind, wraps her arms around him, and he turns to face her.

Check rules: chronological order (woman walks, then bathroom scene), mention appearance (red dress, shirtless, necklace, long hair), spatial (behind, in front of mirror), camera movement—probably follows the action, but the description says "camera perspective and movement" so need to say. The first scene is a view of her walking, then cuts to the bathroom. So camera cuts from doorway to bathroom, then captures their interaction. So maybe "The camera transitions from a view of the woman walking through a doorway to a bathroom scene where a shirtless man stands before a mirror as a shirtless woman with long hair approaches him from behind."

Wait, output format: concise paragraph. Let's make it flow.

"A woman in a red dress walks through a doorway. In a bathroom, a shirtless man with a necklace stands before a mirror as a shirtless woman with long hair approaches him from behind, embracing him and turning to face him. The camera shifts to capture their interaction."

But need to be concise. Check the rules: "concise, chronological paragraph".

Another version: A shirtless woman with long hair enters a bathroom, approaches a shirtless man with a necklace standing before a mirror, and wraps her arms around him from behind as he turns to face her. The scene transitions from a doorway view of the woman in a red dress walking through.

Wait, the first frame is the woman in red dress walking through doorway. So start with that.

"Initially, a woman in a red dress walks through a doorway. Subsequently, in a bathroom, a shirtless man with a necklace stands before a mirror as a shirtless woman with long hair approaches him from behind, embracing him and turning to face him. The camera captures the transition from the doorway scene to the bathroom interaction."

But need to be more concise. Let's cut the "initially, subsequently" part.

"A woman in a red dress walks through a doorway. In a bathroom, a shirtless man with a necklace stands before a mirror as a shirtless woman with long hair approaches him from behind, embraces him, and turns to face him."

Check camera perspective: the first part is a view through the doorway (so camera is outside looking in), then shifts to the bathroom (camera is inside the bathroom, medium shot). So "The camera shifts from a doorway view of the woman walking to

Two people: one shirtless and one with long hair. The person with long hair turns around to face the shirtless person, and they move towards each other and embrace.

No shifting background (wall and door remain static). No fluid/environmental motion (fire, water, smoke, wind) observed.


A clear glass espresso cup containing layered coffee (dark brown base, lighter top) rests on a metal grid in front of a stainless steel espresso machine. A white hand holding a black tool enters from the right, presses the tool down onto the cup, then retracts. The camera maintains a stationary close-up perspective focused on the cup.

A hand (discrete object) interacts with the coffee by stirring or adding a component, showing deliberate physical motion.

The background (coffee machine, grid surface) is static with no shifting or fluid motion. No fire, water, smoke, or wind is present.


A group of six women, wearing athletic attire in colors like black, teal, pink, and white, dance in sync within a well-lit studio featuring large windows and dark walls. They perform coordinated jumping and kicking motions, moving fluidly across the room while maintaining loose spatial formation. The camera follows their movement with a slight handheld shake, capturing their synchronized actions against the backdrop of a pink mat and wall decorations.

Multiple people (dancers) moving with coordinated arm/leg motions; distinct solid objects exhibiting locomotion through synchronized dance movements.

Background (walls, window, radiator) is stationary with no fluid/environmental motion (fire, water, wind, smoke); no ambient phenomena detected.


RAW CAPTION: Got it, let's break this down. The task is to create a concise caption following the rules. First, identify the main subject: a person playing an accordion. Let's check the video frames. The person is standing in a large room with blue walls and wooden floor. They're holding a black accordion, wearing dark clothing. The video shows them moving the accordion's bellows, so the action is playing.

Chronological order: The person starts holding the accordion, then moves the bellows (expand and contract), which is typical for playing. Background has a few people in the distance, but rules say minimal background unless essential. So mention the room briefly, but focus on the main subject's motion.

Appearance: Person in dark clothes, black accordion. Number: one person. Spatial: in the center of the room, with blue walls and wooden floor (background). Camera: seems stationary, no movement mentioned. Rules say conclude with camera perspective and movement. The video starts with the person holding accordion, then playing (moving bellows). So motion is the person manipulating the accordion's bellows while standing.

Now structure the caption: Main subject (person) in action (playing accordion), appearance, motion, background minimal, camera.

Check rules: a) motion and behavior chronological. So first, standing with accordion, then moving bellows. b) appearance: dark clothes, black accordion. c) spatial: center of the room, background people but minimal. d) camera: stationary. e) minimal background. f) exclude text, names.

So draft: A person in dark clothing stands in a large room with blue walls and wooden flooring, holding a black accordion and rhythmically expanding and contracting its bellows to play. In the background, a few individuals are visible near the walls. The camera remains stationary, capturing the person from a frontal perspective.

Wait, check rules: background descriptions minimal unless essential. The background people might not be essential, but the room's features (blue walls, wooden floor) might be part of the setting. But need to be minimal. Let's see. The rules say "minimally describe background unless essential for understanding motion." Since the motion is playing the accordion, the room is the setting, so maybe mention "large room with blue walls and wooden floor" as context, but not too detailed.

Also, number: one person. Appearance: dark clothing, black accordion.

Motion: expanding and contracting bellows (which is the action of playing).

Camera: stationary, frontal.

So rephrase: A person wearing dark clothing stands in a large room with blue walls and wooden flooring, holding a black accordion and moving its bellows rhythmically while playing. A few people are visible in the background near the walls. The camera remains stationary, capturing the individual from a frontal view.

Wait, the rules say "conclude with camera perspective and movement". So the caption should end with that. Let's structure:

First, main subject's motion/behavior: person stands, holds accordion, moves bellows. Then appearance. Then background (minimal), then camera.

Final check: "A person in dark attire stands in a large room with blue walls and wooden flooring, holding a black accordion and rhythmically expanding and contracting its bellows to play. In the background, a few individuals are near the walls. The camera remains stationary, capturing the subject from a frontal angle."

But need to be concise. Let's see the example output. The task says concise paragraph. Let's trim.

"A person wearing dark clothing stands in a spacious room with blue walls and wooden flooring, holding a black accordion and moving its bellows rhythmically while playing. A few people are visible in the background near the walls. The camera remains stationary, capturing the individual from the front."

Wait, "spacious room" is better than "large room". But maybe "large room with blue walls and wooden floor". Also, "rhythmically expanding and contracting its bellows to play" – that's the action.

Check rules: b) briefly describe appearance and number. Number is one person. Appearance: dark clothing, black accordion.

c) spatial relationships: person is in the center (implied by the video), background people near walls.

d) camera perspective and movement: stationary, frontal.

e) background minimal: yes, since background people are mentioned but as minimal.

f) no text, names.

So the caption should flow: main subject, action, appearance, background (minimal), camera.

Let's write it:

A person in dark clothing stands in a large room with blue walls and wooden flooring, holding a black accordion and rhythmically moving its bellows while playing. A few individuals are visible in the background near the walls. The camera remains stationary, capturing the subject from a frontal perspective.

That should be concise and follow all rules.
</think>

A man in black pants and a white shirt is playing an accordion. His hands and torso exhibit subtle movements (e.g., hand motions on keys, slight body sway) due to active physical interaction with the instrument.

The background (blue walls, wooden floor, monitors) is static with no shifting or fluid motion. No fire, water, smoke, or wind is present.


RAW CAPTION: Okay, let's see. I need to generate a concise, chronological paragraph describing the video based on the provided frames. The user gave specific rules, so I have to follow them carefully.

First, the video starts with a person wearing a white hat and a dark vest. They're standing on a platform next to a railing. The background is green, maybe some foliage. The person is handling a dark-colored object, maybe a bag or a piece of equipment. Then, in the next frame, they move slightly, still holding the object. The third frame shows them bending down, possibly placing or adjusting the object on the platform. The fourth frame has them standing up again, maybe adjusting their position. The fifth frame they're looking towards the camera, still holding the object.

I need to describe the motion and behavior in chronological order. Focus on the main subject, which is the person. Appearance: white hat, dark vest, backpack. Number: one person. Spatial relationships: near the railing, on the platform. Background is green but minimal as per rule e.

Camera perspective: the video seems to be handheld, so maybe slight shake. The camera moves a bit, maybe panning or following the person's movement. But the user says to mention camera movement at the end.

Check if any text or names are present. The frames don't have text, so exclude that. No named characters, so okay.

Let me structure the caption:

Start with the person's initial position, then actions in order. Mention appearance briefly. Spatial relations like near the railing. Conclude with camera movement.

Wait, the first frame: person standing, holding object. Then moving, bending, adjusting. The camera's perspective: since it's shaky, maybe "slight shake" as per rule d.

Make sure to keep it concise. Let's draft:

A person wearing a white hat and dark vest stands on a platform beside a metal railing, handling a dark object. They bend forward to adjust the object on the platform, then stand upright while looking toward the camera. The camera remains steady with minor movements, capturing the scene from a frontal angle.

Wait, but the video has some movement. The user says "slight shake" as per rule d. The example in the rules says "slight shake" so maybe "slight shake" in the camera movement.

Check the sample output. Maybe better: "The camera maintains a frontal angle with slight shake, focusing on the person..."

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

So the camera movement is mentioned at the end.

Let me try again:

A person in a white hat and dark vest stands on a platform near a metal railing, handling a dark object. They lean forward to adjust the object on the platform, then straighten up and look toward the camera. The camera remains mostly stationary with slight shake, capturing the sequence from a frontal perspective.

Wait, the frames show movement. The second frame shows the person moving, so "bends down" maybe. Let's see:

First frame: standing, holding object. Second frame: moving, perhaps bending. Third: bending down. Fourth: standing. Fifth: looking towards camera.

So chronological order: person stands, bends down, adjusts object, stands upright, looks at camera.

In the caption, need to be chronological.

"A person wearing a white hat and dark vest stands on a platform beside a metal railing, holding a dark object. They bend forward to adjust the object on the platform, then straighten up and look toward the camera. The camera remains stationary with slight shake, capturing the sequence from a frontal angle."

But rule d says "Conclude with the camera perspective and movement (e.g., top-down, pan left, slight shake)."

The camera perspective here is frontal. The movement is slight shake.

Yes. Also, background is minimal. The green background is mentioned as essential? Rule e says "minimal unless essential for understanding motion." The motion here is the person moving, so maybe the green background is just part of the scene but not essential. But maybe the platform is near water or something, but the frames show greenery. Maybe "a green outdoor setting" but rule e says minimal, so maybe don't mention unless necessary. Since the motion isn't dependent on the background, maybe just "a platform" without the green.

Wait, the first frame shows the person on a platform with a railing, greenery behind. So "a platform beside a metal railing with greenery in the background" but rule e says minimal. So perhaps omit the green background unless it's essential for understanding motion. The motion is the person's actions, so background is minimal. So just mention the platform and railing.

So revised:

"A person wearing a white hat and dark vest stands on a platform beside a metal railing, handling a dark object.

Briefly describe what discrete, solid objects are moving.

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


A person stands in front of a black metal fence, initially adjusting the camera angle. They lift a yellow plastic bag toward the camera, holding it momentarily before lowering it back down. The individual remains positioned centrally in front of the fence throughout, with the overcast sky visible behind. The camera maintains a close-up, slightly shaky handheld perspective, focusing on the person's actions.

A person holding a bag of 'Nour' (text visible) moves their head and brings the bag toward their mouth, demonstrating discrete object motion via hand and head movement.

The fence and sky background show no significant shifting or fluid motion; no fire, water, or smoke is present.


A person with gray hair and a beige shirt grips a hammer-like tool in a close-up shot, then lifts it above their head. The individual, wearing brown pants and shoes, adjusts their stance on a concrete floor marked with yellow-black tape, positioning the less dominant foot forward while stabilizing with the back foot. The camera transitions from a close-up of the hands and tool to a medium shot of the person raising the tool, then focuses on the feet and ground markings.

A man raising a bat and a person stepping over caution tape.

No shifting backgrounds and no fluid/environmental motion (fire, water, wind) observed.


The video opens with a small white sailboat featuring a red and white sail, sailed by a person in a yellow life jacket, moving slowly on calm water. It then cuts to a group of five children wearing yellow and blue life jackets standing on a dock, with an adult in a blue shirt and cap addressing them. The camera perspective shifts from a side view of the sailboat to a ground-level view of the dock scene.

A sailboat (solid object) is moving due to wind-driven forces in the first segment. In the second segment, a group of people (discrete objects) are stationary on a dock.

The water in the first segment shows gentle waves (ambient environmental motion), but the dominant motion is driven by the sailboat's movement. The background (land, dock) in both segments is static and shows no uniform shifting, indicating no camera motion.


A hand with light-colored nail polish approaches a child's eye from the left, holding a small dark object. The hand positions the object near the eye, then withdraws. The camera remains in a close-up, stationary perspective.

A hand holding tweezers interacts with a child's eye, with discrete motion of the hand, tweezers, and eye movements due to physical actions (applying/removing an object from the eye).

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


RAW CAPTION: Okay, let's tackle this video captioning task. First, I need to understand the requirements. The user wants a concise, chronological paragraph describing the video. The main points are focusing on motion and behavior of main subjects in order, mention appearance and number, spatial relationships, camera perspective, keep background minimal, exclude text or names.

Looking at the video frames: The first frame shows a crowded area with people near a railing, maybe a market or street. The second frame has a person in a pink shirt moving. Third frame shows more people, some sitting on a bench. Fourth frame has a person in a pink shirt and others around. Fifth frame is a blur with more movement.

So the sequence starts with a crowded street scene. People are moving, some sitting. The main subjects are the people in the crowd. The person in pink is noticeable. Then there's a shift to someone in a black and white dress, maybe sitting on a bench. The camera seems to pan through the crowd, moving left and right, causing some shake.

I need to structure this chronologically. Start with the initial crowded scene, mention the movement of people, then specific individuals like the pink-shirted person. Then the bench scene with the person in the black dress. Then the crowd moving again. The camera's perspective is handheld, shaky, panning left. Background is busy but not detailed.

Check the rules: No text recognition, no named characters. So avoid specific details like exact numbers, but mention "several" or "a crowd". Spatial relationships: people in front of railings, sitting on benches.

Make sure to mention the camera movement at the end. The user says "conclude with camera perspective and movement". So the last part should state the camera is moving with slight shake, panning left.

Let me piece it together:

"Video opens with a crowded street scene where several pedestrians move rapidly in various directions, including a person in a pink shirt walking near a metal railing. The camera pans left, revealing more individuals, some seated on a bench; a woman in a black dress with white polka dots sits beside a child. The crowd continues to flow around the bench area, with people in diverse clothing colors and styles. The camera movement is handheld and slightly shaky, capturing the dynamic motion of the bustling environment."

Wait, but need to check if it's chronological. The video starts with the initial crowd (frame 0), then moves to the person in pink (frame1), then bench scene (frame2-4), then the next movement (frame5). So the caption should follow the sequence: starts with crowd, then pink shirt person moving, then bench with the polka dot dress, then crowd moving again. Camera pans left and moves with shake.

Wait, the video frames: 0 shows people near railing. 1 shows pink shirt person moving. 2-3 shows people around bench, including someone with polka dots. 4-5 shows more crowd movement.

So the caption should mention the initial crowd, then the pink shirt person, then the bench scene with the black dress person, then the camera movement. But the user says "concise, chronological paragraph", so maybe the main points in order.

Let me check the example output structure. The user provided a format example, so need to follow that. The key is to not be too verbose but hit all the points.

Maybe:

"The video begins with a busy street scene where numerous pedestrians walk past a metal railing. A person in a pink shirt moves through the crowd, followed by a woman in a black polka-dot dress sitting on a bench. The camera pans left, capturing people in various positions around the bench, with the crowd continuing to flow. The handheld camera exhibits slight shake and movement as it navigates the bustling environment."

Wait, but need to mention the number of people? The user says "briefly describe their appearance and number (color, size, orientation)". So "several pedestrians", "a person in pink", "a woman in black polka dots".

Also, "spatial relationships" like "seated on a bench" or "near a railing".

Putting it all together:

"Video starts with a bustling street filled with moving pedestrians, including a person in a pink shirt walking past a metal railing. The camera pans left, revealing a woman in a black polka-dot dress sitting on a bench with a child beside her. More people flow around the bench area, some carrying bags. The handheld camera moves with slight shake, capturing the dynamic crowd motion in the background."

Check if it's chronological: starts with street, then pan left to bench, then crowd around bench. Camera movement described at the end.

Make sure background is minimal. So "bustling street", "dynamic crowd motion" is okay.

Avoid text, names. Yes.

Looks good. Now, check the rules again.

a) Motion and behavior


The video opens with a black screen, then transitions to a room with orange walls where a blonde woman in a pink checkered off-shoulder top and shorts kneels on an orange mat, applying a white substance to the torso of a person lying on their back in white underwear. The woman moves her hands in smooth motions across the person’s back and chest, maintaining a position in front of them. The camera remains stationary throughout, capturing the scene with minimal background details.

Two people: one lying down (stationary) and one kneeling (moving hands and arms in a rhythmic massage motion). The motion is due to physical contact and manipulation of the body.

The background (orange wall, lamp, bed) is static with no shifting or fluid motion. No fire, water, smoke, or wind detected.


A man in a light blue shirt smiles with closed eyes in a close-up shot, then opens his eyes. The camera shifts to a wider view showing him seated at a café table, drinking from a cup, as a woman in a white dress walks past the café window. The camera remains static in the café scene.

The person's head and upper body show discrete, solid movement (smiling, head tilt) in the first scene; no other objects exhibit clear physical motion beyond this.

In the initial frames (0.0-3.7 seconds), static background elements (wall, decor) show no uniform shift. In the window scene (4.2-5.0 seconds), no significant fluid/environmental motion (fire, water, wind) dominates; only subtle potential tree sway from wind is present but not dominant.


Four individuals in black athletic wear move in a diagonal line across a blue-floored corridor. They begin leaning forward with bent knees, then step and shift positions toward the camera, maintaining synchronized motion. The camera pans slightly left and moves forward, capturing their coordinated movement with a slight shake.

Multiple individuals in black uniforms are performing synchronized movements: bending forward, stepping laterally, and extending arms. Their motion is discrete and solid, driven by intentional locomotion and coordination, with clear bounding box tracking possible.

The background elements (walls, ceiling lights, blue flooring) remain stable with no uniform shifting or fluid motion (fire, water, smoke, wind). The scene is an indoor environment with controlled lighting and no environmental fluid dynamics.


A child with short dark hair, wearing a white sleeveless shirt and blue pants, sits on a tiled floor and plays a blue toy drum set with yellow and silver accents. The child holds a drumstick, striking the drums and moving their hands rhythmically, occasionally lifting the stick. The camera maintains a top-down view with slight shake, capturing the child’s interaction with the instrument.

A child is moving their arms and drumsticks to interact with a drum set, exhibiting clear physical motion of solid objects.

Static background elements (walls, floor tiles) show no uniform shifting; no fire, water, or wind present in the scene.


A person in a blue top and black pants kneels on the floor, petting a small white dog with brown patches wearing a green bandana; the person then adjusts the bandana while the dog stays still, positioned behind and to the side of the dog. The background includes a bed with a pink blanket and a fan, captured from a slightly shaky close-up angle.

A person's hand moves to pet a dog; the dog moves its head and body in response to the touch.

Background elements (bed, fan, furniture) are stationary; no fire, water, smoke, or wind observed.


A man wearing a green sleeveless shirt, black shorts, and black-red athletic shoes lifts a barbell with green weight plates. He begins in a squat position on a white floor, rises to stand while holding the barbell at shoulder height, then lifts it overhead before lowering it back down. The background is a plain white space. The camera remains stationary in a side angle view.

A person (discrete object) performs a barbell lift: bending down to grip the barbell, lifting it to the chest, then overhead, and lowering it back down. The barbell moves as a solid object due to the person's physical force application.

The background consists of a plain white wall and floor with no visible shifting or movement. No fluids, fire, water, smoke, or wind are present, so ambient environmental motion is absent.


tags.  Let me structure it:  The video shows a group of people dressed in Santa-themed attire on a subway. Initially, a person with a white Santa hat and fur trim holds a pole while standing near others in red and white costumes. As the video progresses, individuals interact closely, with one person raising an arm and another holding a yellow object. The camera shifts slightly, capturing the crowd’s movements and expressions as they navigate the subway car, maintaining a close-up perspective on the group’s dynamic interactions. The subway’s interior is visible but not emphasized, focusing primarily on the participants’ coordinated motion and festive appearance.  Wait, but the rules say to mention spatial relationships if relevant. Maybe "A person in a Santa hat stands in front of others in Santa costumes on a subway." Hmm.  Wait, need to be chronological. So first, the initial scene. Then what happens next.  Let me go frame by frame:  Frame 0: Person in Santa hat (white fur, red hat) holding a pole. Others in red and white costumes. Subway setting.  Frame 1: More people in Santa costumes, one holding yellow object (maybe a lollipop), others waving.  Frame 2: Person in Santa hat is moving their arm, others behind.  Frame 3: The person with the pole is holding it up, group crowded.  Frame 4: A girl with green backpack and headphones is talking to someone.  Wait, the user says to focus on the main subjects' motion and behavior in chronological order.  So maybe:  A group of individuals in Santa-themed attire move through a subway car. Initially, a person with a white Santa hat and red fur trim holds a pole, while others in red and white costumes stand nearby. The camera captures them interacting closely, with some raising arms and another holding a yellow object. As the video progresses, the crowd shifts positions, and a person wearing headphones converses with a peer. The camera maintains a close-up perspective, panning slightly to follow the group’s movements within the subway environment.  Check if the rules are followed:  - Motion and behavior in chronological order: Yes.  - Appearance and number: Mentioned Santa attire, yellow object, headphones.  - Spatial relationships: "close to," "within the subway."  - Camera perspective: Close-up, panning.  - Background minimal: Yes.  - No text or named characters: Correct.  I think that's it. </think>  <caption_output>A group of people dressed in Santa-themed attire move through a subway car.

The subway’s interior remains visible but unobtrusive, focusing on the participants’ festive movements and expressions.

People in Santa costumes are moving within the train, shifting positions, adjusting grips on poles, and interacting with one another.

The train interior background (walls, poles) remains static without uniform shifts; no fire, water, smoke, or wind motion observed.


A swimmer wearing a dark swim cap and swimsuit swims freestyle in a pool lane bordered by yellow and black lane dividers, moving forward with alternating arm strokes and kicking legs; the swimmer approaches the wall, pushes off, and continues swimming. The camera maintains a top-down perspective, following the swimmer’s progression through the water.

A swimmer (discrete, solid object) is moving through the water by performing strokes; the motion is due to the swimmer's locomotion.

The background (lane dividers) is static and does not shift. The water is displaced by the swimmer but is not the dominant motion; the swimmer is the main subject.
