RAW CAPTION: Got it, let's break down the video. First, there's a hand holding a white ball with "SPORTCRAFT" and a star logo. The hand moves the ball towards a green cup on a speckled countertop. The background has brown diamond-patterned tiles. Then the hand drops the ball into the cup. The green cup is near the wall, and the tiles are behind. Camera stays static, maybe a slight focus shift but no movement. Need to describe chronologically: hand with ball, moving to cup, dropping ball. Mention colors: white ball, green cup, brown tiles. Spatial: hand enters frame, ball moves towards cup, drops into it. Background minimal, just the tiles. Camera perspective is static, close-up on countertop.

Wait, the video starts with the countertop and tiles. Then hand appears with ball. Ball is moved to the cup, which is on the counter. Then the hand points? Wait, no: frame 0 is countertop, frame 1 hand holding ball, frame 2 hand moves ball to cup, frame 3 ball is in cup, frame 4 hand points? Wait the description says:

[0.0] countertop with tiles.

[1.0] hand holding white ball with logo (SPORTCRAFT, star) over counter.

[2.0] hand releases ball, ball moves to green cup (cup is there), ball is near cup.

[3.0] green cup is in place, ball is now in cup?

Wait the frames: 0 is countertop, 1 is hand holding ball, 2 is hand moving ball into cup, 3 is cup (ball inside?), 4 is hand pointing. Wait no, the user's provided frames: [0.0] first frame is countertop, then [1.4] hand with ball, [2.5] hand releases ball (ball moves to cup), [3.6] cup is there, [4.7] hand points to cup.

Wait the sequence:

- Start: countertop with brown diamond tiles in background.

- Then a hand appears holding a white ball (with green logo and star) above the counter.

- Hand moves the ball towards a green cup positioned against the wall (to the right of the tiles).

- The ball is dropped into the green cup (now the cup is visible with the ball inside).

- Then a hand points towards the green cup (which now contains the ball).

Wait, need to check the frames:

Frame 0: countertop and tiles.

Frame 1: hand holding ball (white, with green logo and star).

Frame 2: hand moves ball towards green cup (which is now visible), then releases it.

Frame 3: the ball is now in the green cup.

Frame 4: hand points to the cup.

But in the user's description, the video is:

[0.0] countertop, tiles.

[1.4] hand holds white ball (SPORTCRAFT, star) over counter.

[2.5] hand releases ball, ball moves to green cup (cup is now visible, positioned against the wall).

[3.6] green cup is in place (ball inside).

[4.7] hand points to cup.

So the main actions:

1. Hand holds white ball (with logo, but we can't mention text; so just white ball with green logo and star, but rule f says exclude text recognition, so maybe just "white ball" since we can't describe the logo).

Wait rule f: exclude text recognition. So "SPORTCRAFT" is text, so can't mention. So just describe the ball's appearance: white with a green logo and a star (but text isn't part of it, maybe just "white ball" and the logo is part of the design, but since text is excluded, perhaps the color and the logo's color (green and star, but not text). Wait rule f: "Exclude text recognition, named characters, or stylistic analysis." So the word "SPORTCRAFT" is text, so we can't say that. So the ball is white with a green logo and a red star? Wait in the video description, the ball is white with "SPORTCRAFT" (green) and a red star. But since we can't recognize text, we just say white ball with a green logo and a star.

Wait, but maybe the ball's appearance: color is white, has a green logo (but no text), and a star. But the rules say exclude text recognition, so the fact that it's a logo isn't text, so it's allowed. But since the user is to avoid text, just describe the visual.

So the ball is white, with some green and red (star) markings. But rule f says exclude text recognition, so even if the logo

A white ball is held and rotated by a hand (0.0-1.0s), then moved away. A green cup is slightly repositioned by a hand (4.1-4.5s). Both are solid objects moved by explicit physical forces (hand manipulation).

The tiled wall and countertop background remains static throughout the video with no uniform shifting or fluid/environmental motion (fire, water, smoke, wind). No ambient phenomena are present.


A red circular shape expands to cover the left side of the screen as a red panel slides in from the left. A person in a white shirt is seen painting a wall with a roller, positioned to the right of the red panel. The person moves their arm up and down to apply paint. The camera remains static, capturing the person from the side.

A person (solid object) is moving their arm to paint a wall, indicating explicit physical motion due to locomotion and tool use.

No ambient environmental motion (fire, water, smoke, wind) present. The background wall is static in the painting scene, with no fluid or gaseous elements dominating motion.


A person wearing a red short-sleeve shirt, dark hair, and a blue wristband reclines on a green surface, holding a phone with both hands. They adjust their grip and move their fingers across the phone screen. The camera maintains a close-up perspective with slight movement.

A person in a red shirt is seated, holding a phone, with minimal head and body movements consistent with natural locomotion (posture adjustments, slight head turns).

The background (dark green wall and static objects) shows no shifting or uniform movement. There are no fluid or environmental motions (fire, water, smoke, wind) present.


A group of pedestrians, including individuals in blue and white shirts, cross a street in front of a red jeepney with an open rear. The jeepney moves left, while white and yellow taxis drive past. Pedestrians continue walking in various directions near a green utility pole. The camera maintains a top-down perspective, panning left to follow the traffic flow.

Multiple solid objects (pedestrians, vehicles) exhibit locomotion: pedestrians walk across the street, vehicles move along the road, and a red bus advances forward.

No uniform shifting of static background elements (road, buildings, parked vehicles) observed. No fire, water, or smoke present; environmental motion is negligible.


A shirtless man sits outdoors at night, facing right, then turns his head toward the camera while gesturing with his right hand. The camera, handheld with slight movement, captures him against a dark background with faint distant lights.

The shirtless man is moving his head and upper body, likely due to talking or gesturing.

The background appears stable with fixed lights and structures; no significant fluid or environmental motion (fire, water, smoke, wind) detected.


A man in white clothing performs a dynamic acrobatic sequence: he starts in a standing position, executes a low kick, transitions to a handstand, lowers himself to the floor, and rises. Another person in white joins him, engaging in movement. Seated individuals in white surround them, some playing instruments or observing. The camera remains stationary, capturing the action from a fixed perspective.

Two people in white uniforms are moving: one performs dynamic martial arts moves (kicking, sweeping, and ground manipulation), while the other is thrown and swept by the first. These are solid, distinct objects with clear physical interactions (contact, impact, locomotion).

The background elements (wall decorations, chairs, floor) show no shifting or uniform motion. No fire, water, smoke, or wind is present; the environment is static and unaffected by ambient forces.


RAW CAPTION: Got it, let's break this down. The video starts with a person in dark clothing. First frame: close-up of legs and torso, maybe bending down. Then frame 2: a woman with long dark hair, holding up a black garment. She's in a room with a door and kitchen visible. Frame 3: she's putting on the black outfit, which has a zipper. Frame 4: she's adjusting the top part, like a vest or jacket. Frame 5: she's wearing the black outfit, now standing straight.

Need to describe in chronological order. Main subject is the woman. Appearance: long dark hair, black clothing (dress or jumpsuit? The video shows her putting on a black garment with a zipper, then adjusting). Motion: starts with her holding the garment, then putting it on, adjusting the straps or zipper. Spatial: she's in a room with a door to the left, kitchen in the background. Background is minimal, so maybe mention door and kitchen briefly. Camera perspective: starts close-up, then shifts to medium shot. Camera movement: probably steady, but the video might have slight shake.

Rules: focus on motion and behavior chronologically. So first, she's handling the black garment (holding it up), then putting it on, adjusting it. Mention appearance (long dark hair, black clothing). Spatial: room with door and kitchen. Camera: starts close-up, then medium shot, slight shake maybe? Wait, the first frame is very blurry, then clearer. The video moves from a close-up of the body to a medium shot of her putting on the outfit.

Let's structure: "A woman with long dark hair is seen putting on a black garment. She initially holds the garment up, then pulls it over her head, adjusts the straps, and stands upright in a room with a door and kitchen visible in the background. The camera shifts from a close-up of her upper body to a medium shot as she completes the action, with a slight shake."

Check rules: a) motion chronological: holding up, pulling over, adjusting, standing. b) appearance: long dark hair, black garment. c) spatial: door and kitchen in background. d) camera: close-up to medium shot, slight shake. e) background minimal but essential? The kitchen and door are part of the scene but not essential for motion. Wait, rule e says "minimally unless essential". So maybe just mention the room, door, kitchen briefly. f) exclude text, etc.

Wait, the initial frames: first frame is very blurry, showing legs and torso, then frame 2 shows her face, then putting on the garment. So the sequence: she's in the process of putting on a black outfit. The movement is from holding the garment (frame 2) to putting it on (frames 3-5).

So the caption should be: "A woman with long dark hair puts on a black garment. She holds it up, pulls it over her head, and adjusts the straps before standing upright. The scene occurs in a room with a door and kitchen visible in the background, with the camera shifting from a close-up to a medium shot."

Check for conciseness. Let's see:

- Main subject: woman with long dark hair.
- Motion: holds garment up, pulls over head, adjusts, stands.
- Appearance: black garment.
- Spatial: room with door and kitchen (minimal but necessary context).
- Camera: close-up to medium shot.

Yes. Need to be concise. Let's tighten: "A woman with long dark hair puts on a black garment, holding it up, pulling it over her head, adjusting straps, and standing upright. She is in a room with a door and kitchen visible in the background as the camera shifts from a close-up to a medium shot."

But the rules say "concise, chronological paragraph". Maybe: "A woman with long dark hair holds up a black garment, pulls it over her head, adjusts the straps, and stands upright in a room with a door and kitchen visible in the background. The camera shifts from a close-up of her upper body to a medium shot."

Wait, the first frame is blurry legs, then she's moving. Maybe the sequence is: the video starts with her bending down (maybe adjusting clothing), then she holds up the black garment, puts it on, adjusts, and stands. But the key motions are holding the garment, putting it on, adjusting.

Let me check the frames:

[0.0] - blurry, legs and torso, maybe bending.

[1.4] - she's lifting the garment up, showing her face, long dark hair.

[2.5] - she's holding the garment, adjusting.

[3.6] - putting it on,

A person (discrete solid object) performs explicit physical actions: adjusting a black dress, lifting it over shoulders, and positioning it against the body. Hand and body movements are controlled and deliberate, indicating locomotion or intentional manipulation.

Background elements (doors, walls, indoor fixtures) remain static with no uniform shifting or fluid motion (e.g., fire, water, smoke). No environmental fluid dynamics detected.


A person in a light gray long-sleeve top and black shorts sits cross-legged on a brown yoga mat, adjusting their legs by pulling one foot toward their body while using hands to grasp the foot, maintaining a top-down static camera angle.

A person's legs and hands are moving discretely as they adjust their posture during a yoga stretch. The person's limbs exhibit controlled motion consistent with intentional physical movement.

The background consists of a static wooden floor and wall with no shifting or fluid motion. No environmental elements like fire, water, or smoke are present.


RAW CAPTION: Got it, let's break down the video frames.

First frame (0.0s): A person in a dark outfit is mid-air, jumping or flipping. Background is an outdoor area with a building, some structures, and a clear sky.

Second frame (0.6s): The person is still in motion, maybe landing or continuing the jump. The background has the same building, but now there's a vehicle (like a truck) visible. The scene is still outdoors.

Third frame (1.3s): The scene shifts indoors. There's a gymnastics setup with mats (red, blue). A person in a yellow shirt is running or moving. Other people are around, like a child in white and an adult in blue.

Fourth frame (2.0s): Inside a gym, more mats. A person in red pants is moving towards the mats. There's a child in white standing near the mats. The background has gym equipment and walls.

Fifth frame (2.7s): Inside the gym, a person in yellow is on a blue mat. Others are around, including a child in red and white. The background has a high ceiling, lighting, and gym apparatus.

Now, need to describe chronologically. Start with outdoor: person in dark outfit jumping. Then transition to indoor gym. Mention movements: first frame, person jumping; second frame, possibly landing or another move; then third to fifth frames, moving to gym, people on mats.

Check rules: focus on motion, main subjects, chronological. Number, appearance, spatial. Conclude with camera movement.

Background: initial outdoor (building, truck), then indoor gym.

Main subjects: outdoor person (dark outfit), then indoor people (yellow shirt, red pants, child in white, etc.)

Chronological order:

1. Outdoor: a person in dark clothing is airborne, jumping or flipping. Background includes a building and parked vehicle.

2. Transition to indoor gym: the scene shifts to an indoor space with colorful gymnastics mats (red, blue). A person in a yellow shirt moves across the mats, while other individuals (e.g., a child in white, a person in blue) stand nearby.

3. In the gym, the person in yellow continues moving on the blue mat, with another individual in red pants approaching, and a child in white nearby.

Camera movement: starts with a static shot of the outdoor jump, then transitions to a pan to the indoor gym, with slight shakes.

Wait, but the frames are sequential: 0.0s to 2.7s. So:

- Frame 0.0: Person in dark clothing jumps outdoors, background building.

- Frame 0.6: Person still in motion (maybe landing), background vehicle.

- Frame 1.3: Shift to indoor gym, person in yellow runs on mats, others around.

- Frame 2.0: Indoor gym, person in red pants moves towards mats, child in white nearby.

- Frame 2.7: Gym, person in yellow on mat, others (red and white, blue shirt) present.

So the sequence: outdoor jump → indoor gym with people moving on mats.

Write a concise paragraph.

Focus on motion:

First, a person in dark attire jumps upward against a backdrop of a building and parked vehicle. The scene transitions to an indoor gymnastics facility where individuals in colorful attire (yellow, red, white) move across red and blue mats, with some standing nearby. The camera shifts from an outdoor static view to a slightly shaky indoor pan, capturing the motion.

Check rules: no text, no named characters, minimal background.

Let's structure:

"At the beginning, a person in dark clothing is airborne in an outdoor setting with a building and parked vehicle visible. The scene then transitions to an indoor gymnastics area where multiple individuals move across red and blue mats; a person in yellow runs, while others in white and blue stand nearby. The camera shifts from a static outdoor shot to a shaky indoor pan, following the movements within the gym."

But need to be concise.

Another approach:

"A person in dark clothing jumps outdoors before the scene shifts indoors to a gym where a person in yellow runs across red and blue mats, with others in white and blue moving nearby. The camera transitions from a static outdoor view to a shaky indoor pan."

Wait, the first two frames are outdoor, then indoor. Let's check the video description.

The user provided 5 frames:

0.0s: outdoor, person jumping.

0.6s: outdoor, person still moving, vehicle.

1.3s: indoor gym, person in yellow moving.

2.0s: indoor gym, person in red pants moving.

2.7s: indoor gym, people moving.

So main subjects:

- Outdoor: dark-clad person (jumping, airborne)

- Indoor: yellow-shirted person, red-pants person,

The primary objects moving are two athletes: one vaulting outdoors and another running and doing a handstand indoors. Other gym attendees are also moving.

The background (buildings and gym walls) is stationary; no fire, water, smoke, or wind is present. The video has a glitch (horizontal lines) but this is a recording artifact and not environmental motion.


Two boys interact closely: the left wears a light gray polo shirt, the right a white T-shirt with red and orange stripes. Initially standing side by side, they move dynamically—shifting positions, with the gray-shirted boy occasionally in front of the white-shirted one. Both gesture and turn toward the camera, their movements captured by a shaky, close-up camera that pans slightly between them.

Two children are moving: one in a light blue shirt moves from left to center and lifts a shirt, while the other in a white shirt gestures and points.

The background consists of indoor walls with no fire, water, smoke, or wind. The background does not shift uniformly (handheld motion is non-uniform).


A person with long dark hair and an orange sleeveless top sits at a table. They hold a small blue object in their right hand while manipulating a white object with their left hand, moving it toward the blue object, then bringing the white object closer to their face. The background includes hanging clothes, and the camera remains fixed in a close-up perspective.

A person's hand and arm are moving in discrete motions (e.g., holding an object, gesturing) with clear physical interactions.

Background elements (clothes hanging) are static; no fluid/environmental motion (fire, water, wind) is observed.


A person in a white shirt and beige cap repeatedly hammers a chisel into a large gray rock on the ground, striking it multiple times. The camera pans upward to reveal the person’s face and upper body as they continue the action, then shifts to show a second individual in a red shirt and white vest standing near a white railing in the background. The scene occurs outdoors with dirt, rocks, and a house visible. The camera moves slightly, maintaining a close-up on the hammering activity before widening to include the surroundings.

A man in white shirt and cap swings a hammer to strike rocks; the hammer moves in discrete striking motions while the rocks are stationary except for localized fracturing.

Background elements (house, trees, ground) remain stable with no uniform shifting; no fire, water, smoke, or wind dominates the scene. Environment is calm and static.


The video opens with five seated individuals at a table, engaging in discussion while facing a seated audience. The panelists exhibit subtle gestures and shifting postures during their interaction, while audience members remain mostly stationary, occasionally adjusting their positions. The camera maintains a static frontal perspective throughout the sequence.

Discrete solid objects (people seated in the audience and speakers on stage) exhibit subtle movements (e.g., head turns, slight posture shifts) due to human locomotion, but no significant collisions or force-driven motions are visible.

The background consists of a static conference room setting (walls, stage, screen) with no visible shifting or environmental fluid motion (fire, water, smoke, wind). Background elements remain stationary throughout.


A person with blue sleeves adjusts a white paper cutter’s blade upward, then positions a stack of white papers onto the cutter’s surface. The camera maintains a top-down perspective throughout, capturing the sequence on a dark, patterned surface.

The moving objects are the person's hands and the white paper, which are being manipulated to cut the paper.

The background (table surface and paper cutter base) is static with no fluid motion (fire, water, smoke, wind).


Hands with light skin and rings flatten a white fabric with gray patterns on a light surface, then fold the fabric in half. The hands place a white plastic tool set with red polka dots and colorful buttons onto the folded fabric, positioning it centrally. The camera maintains a static top-down view throughout the sequence.

Hands are moving solid objects: unfolding/rolling a sheet of paper and placing a rectangular tray with compartments on the surface.

The background (white surface with red and floral elements) remains static; no shifting backgrounds or fluid/environmental motion (fire, water, wind) is observed.


A man in a dark blue shirt with green accents draws a black bow labeled "SACHER" then lowers it, turns, and walks along a grassy path toward a wooden building with a rocky cliff backdrop. The camera follows him in a medium shot as he moves forward.

A person is actively manipulating a bow, adjusting their stance and equipment. This involves discrete, solid motion (e.g., arm movements, body positioning) driven by intentional physical actions.

The background includes a rocky wall, grass, a building, and a pathway. These static elements show no uniform shifting across frames, indicating no significant ambient environmental motion (fire, water, smoke, wind) or camera-induced background movement.


A person in a white cap and light shirt holds a rope attached to the snout of a large gray alligator partially submerged in murky water near a wooden fence. The alligator moves forward through the water, pulling the rope, while the person steps back onto the muddy bank. The alligator continues advancing toward the shore as the camera remains stationary, capturing the interaction from a ground-level perspective with minimal background detail.

The alligator is moving through the water via locomotion (swimming). The person is standing and holding a pole, with minimal movement.

The background (wooden fence) is static. The water is disturbed by the alligator's movement but is not the dominant motion.


A person in a blue shirt and black pants is seen lying in a sandpit before sprinting on a red track, accelerating toward the sandpit, and then jumping to land within it. The camera captures the motion from a side angle, tracking the athlete's sprint and jump sequence.

A person (athlete) is running and jumping. The motion is due to his own physical movement (locomotion and jump).

The background (stadium stands, grass field, runway) is stationary. No fluid or wind motion is present.


A man in a dark polo shirt, light trousers, and dark cap stands on a sunlit golf green, holding a putter; he swings the club, striking a golf ball that rolls forward. The camera then shifts to a side angle as he bends forward, observing the ball's trajectory.

The golfer (person) moves by swinging the golf club and bending to observe the ball; the golf ball moves after being struck by the club due to physical collision.

The background (trees, house, and green) remains largely stationary with no uniform shifting. Minimal wind-induced tree sway is visible but not dominant; no fire, water, smoke, or significant fluid motion is present.


A man in red shorts, black shirt, and white sneakers lifts a barbell with weight plates from the ground to a standing position, then lowers it back down. The camera captures the action from a top-down angle with slight movement.

A person performing weightlifting (deadlift motion) with a barbell and weights; the barbell and person exhibit discrete, physics-driven motion due to exertion.

Background elements (door, furniture, floor) remain consistent without uniform shifting or fluid motion; no fire, water, or smoke observed.


A woman with brown hair in a bun applies a product to her eye while seated at a table. The camera zooms in to closely focus on her eye and hand as she continues the precise application motion.

The woman's hand is moving to apply makeup, which is a discrete solid object motion.

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


RAW CAPTION: Okay, I need to create a concise chronological caption for this video. Let me start by watching the video frames provided.

First, the scene is an indoor pool. There's a child in the water. The main subject is a boy with blonde hair swimming. He's wearing red swim trunks and blue goggles. He's doing a freestyle stroke, moving his arms in a circular motion. The camera follows him as he swims towards the foreground.

In the background, there are other people: maybe a few kids and an adult. They're near the edge of the pool, but the focus is on the boy. The pool has lane dividers, and the walls have some colorful murals or decorations, like fish and balloons. But the rules say to keep background descriptions minimal unless essential. So maybe just mention there are other swimmers in the background.

Chronologically, the boy starts on the left side, swims forward, comes closer to the camera. The camera seems to be moving slightly to follow him, maybe a slow pan. The water is clear, the pool is indoor, but maybe not necessary to mention the indoor part unless it's relevant.

The caption needs to mention motion, appearance (blonde hair, red trunks, blue goggles), number (mainly one boy, others in background), spatial relationships (he's swimming towards the camera, others in background). Camera perspective is following the boy, maybe a slight pan.

Let me structure it step by step:

1. Start: A blonde-haired child in red swim trunks and blue goggles swims freestyle in the pool.
2. Motion: Moves forward, arms alternating, head above water.
3. Background: Other swimmers near pool edge.
4. Camera: Follows the child, slight pan, stays at water level.

Check if all rules are met: motion, behavior chronologically, appearance details, spatial relationships (others in background), camera movement. Avoid background details unless essential. Mention the pool is indoor but maybe not necessary. The main thing is the boy's movement.

Let me check the output format. Must be in <caption_output> tags. Keep it concise. Let's draft:

"A blonde-haired child wearing red swim trunks and blue goggles swims freestyle through the indoor pool, moving forward with alternating arm strokes. The child’s head emerges periodically as they navigate the water, while other swimmers remain near the pool's edge in the background. The camera follows the child's progression with a slight pan, maintaining a water-level perspective."

Wait, the rules say to exclude text recognition, named characters, etc. So "blonde-haired" is okay since it's appearance. "Red swim trunks" and "blue goggles" are appearance. Mentioning "indoor pool" is okay as it's setting. The other swimmers are in the background. Camera follows, slight pan, water-level perspective.

Check if "swims freestyle through the indoor pool" is correct. The video shows the child moving in the pool, so "through" might be okay. Alternatively, "in the indoor pool."

Wait, the problem says "chronological paragraph," so start from the beginning. The child is swimming, moving towards the camera. The camera follows.

Another check: "other swimmers remain near the pool's edge in the background" – correct. "Camera follows the child's progression with a slight pan, maintaining a water-level perspective."

Yes. Let me see if it's concise. Maybe trim a bit. Maybe "A blonde child in red trunks and blue goggles swims freestyle, moving forward with arm strokes in the indoor pool. Other swimmers are visible near the pool edge. The camera follows the child with a slight pan, keeping a water-level view."

Hmm. "Blonde child" is okay. "Trunks" instead of "swim trunks". The rules allow "color, size, orientation" but size isn't specified. Maybe "blonde-haired child wearing red swim trunks and blue goggles."

Wait, the original video description mentions the child has red swim trunks, so that's specific. The goggles are blue. So including those details.

Let me check the example output. The user provided an example but in this case, the task is to generate the caption. The key is to be concise, chronological, mention appearance, motion, spatial relationships, camera movement.

Final draft: A blonde child wearing red swim trunks and blue goggles swims freestyle in an indoor pool, moving toward the camera with alternating arm strokes. Other swimmers are visible near the pool's edge. The camera follows the child's motion with a slight pan, maintaining a water-level perspective.

Wait, the problem states to exclude text recognition, named characters, etc. So "blonde child" is fine. "Red swim trunks" is appearance. The pool is indoor, but maybe just "pool" is enough. Wait, the video is

A single swimmer (person) is moving through the water using freestyle strokes; the motion is driven by the swimmer's propulsion and water resistance.

The background (walls and poolside) is static. The water has ripples due to the swimmer's motion, but the water is not the dominant motion source (it's the medium for the swimmer's locomotion).


A toy train set with blue tracks and colorful components rests on a green and yellow patterned blanket. A child in a green shirt enters the frame, lying on the blanket and interacting with the toys, moving the train set. The camera pans slightly downward to reveal the child’s position relative to the toys.

A child is lying on the mat, exhibiting slight movements (e.g., shifting position, hand movements).

The background (mat with green and white patterns) shows no significant shifting; no fluid/environmental motion (e.g., fire, water, wind) is present.


A nighttime outdoor scene shows multiple people in casual clothing (white shirts, dark pants, red tops) moving around a central individual in a white and blue patterned outfit. Initially, a man in a white shirt grasps another’s arm, then the group collectively pushes and dances around the central figure, with some members moving left and right. The camera pans slightly to follow the crowd’s dynamic interactions, capturing their energetic motions as they disperse across the frame.

Multiple discrete solid objects (people) are moving: a person in a white suit interacting with others, a person in a blue shirt running, and others holding red objects. Motion arises from explicit locomotion and collisions (e.g., physical contact between individuals).

The background consists of a dark night scene with fixed ground and distant lights showing no fluid environmental motion (e.g., fire, water, smoke, wind). Static elements like the ground and distant lights remain stationary without uniform shifting.


A woman in a black tank top, black leggings, and turquoise sneakers performs a switch climber exercise on a concrete floor against a plain white wall. She starts in a plank position, then alternates her legs by drawing one knee toward her chest while extending the opposite leg, repeating the motion in a rhythmic sequence. The camera maintains a static, frontal perspective throughout, focusing on her full-body movement with minimal background detail.

A person (discrete solid object) is performing a lunge exercise with visible locomotion (weight shifting between legs and knee bending).

The background (concrete floor and wall) is static with no shifting or environmental fluid motion (fire, water, smoke, wind) observed.


A person in a black top and blue jeans rhythmically strikes a large drum with their hands, moving them up and down to press the drumhead. The drum has a light-colored head and colorful decorative edges. The camera maintains a close-up view focusing on the hands and drum, with an urban background partially visible.

The person's hands (solid, discrete objects) are striking a drum. The motion is rhythmic and driven by the force of the hands hitting the drum, which causes the drumhead to vibrate.

Background shows a cityscape with buildings and water; no fire, water flow, smoke, or wind effects. Background elements are static with minimal movement (likely due to the subject's motion, not ambient).


Two women assist a shirtless baby in a blue basin; one wears a green shawl with a yellow skirt, the other a black-and-white polka-dot headscarf. The baby cries as the women wash their hands and upper body. The camera zooms in on the baby’s face, focusing on hands and upper body while the women continue washing. Background includes a brick wall and scattered sandals.

Child is moving (squirming, crying) due to washing; women are moving hands to wash the child. Solid objects interacting via physical forces.

Background (brick wall, ground) shows minimal shift, not uniform. No dominant fluid/environmental motion; water is contained and static in the basin.


A person wearing a yellow helmet and dark clothing stands on a raised metal platform, leaning forward to spray a misty stream. They adjust their stance slightly while continuing the spraying motion. The background features blurred greenery. The camera moves with a gentle pan to the right, following the subject.

A person wearing a yellow helmet is moving from a platform structure downward (possibly falling or jumping), which is the main discrete object motion.

The background (trees and structure) is static. There is a minor mist in the air, which is a result of the activity but not a dominant fluid/environmental motion.


A man stands at a podium speaking to an audience. A person in a blue shirt and dark pants enters from the left side of the stage, walks across the stage, and exits to the right. The camera remains stationary, capturing the speaker and the moving individual against a backdrop of seated panelists.

Solid objects (people) are moving: the speaker at the podium exhibits minor gestures and body movements, while band members and audience members show subtle locomotion due to speaking, playing instruments, or seated adjustments.

The background elements (stage, screen, banners, flags) remain static with no uniform shifting or fluid environmental motion observed. No fire, water, smoke, or wind-driven motion present.


Two individuals, one in white shirt and blue pants, the other in white shirt and white pants, perform a dance routine in the center of a room, moving in a circular pattern across the wooden floor as seated onlookers in yellow and white shirts observe from the periphery; the drum sits to the right, and the camera remains stationary throughout.

Two main subjects (a person in white and a person in blue) are engaged in martial arts movements, including kicks and defensive maneuvers. The sitting audience is mostly static.

The background (walls, door, painting) is static with no shifting. No fire, water, smoke, or wind effects are present.


A person in a black-and-white striped shirt and purple oven mitt stirs a thick, pale yellow liquid in a large metal pot on a stovetop. They then lift the pot using the mitt and move it toward a wooden wall with hanging pans, while wearing a dark cap. The camera begins with a close-up of the pot, then pans slightly to follow the person's movement toward the wall. Background details are minimal, focusing on the action.

The person (wearing striped shirt and purple gloves) is stirring the pot and moving the pot. The spoon is being used to mix the food, causing the food to move.

Background (wooden wall, hanging pots) is static. The food in the pot is being stirred by the person, which is controlled movement, not environmental fluid motion.


A woman in a black swimsuit crouches on the sandy beach, handling a red object and a green item. She then stands, turns, and walks away toward the right. In the background, beach chairs and a person in a pink top are visible. The camera remains static throughout.

A woman in a black swimsuit is moving: she bends over, sits up, and adjusts her clothing. The motion is discrete and self-propelled.

The ocean has gentle waves but they are not the dominant motion. The sky is clear and the distant building is stationary. The background does not show uniform shifting, so no camera motion is indicated. The ambient elements (waves) are present but not dominant.


Players in red jerseys and white socks walk across a grassy field, passing a referee in a yellow wheelchair positioned near the center. The camera pans left, following the movement of the players as they traverse the field, with the wheelchair referee remaining stationary in the background.

Discrete solid objects (people in red uniforms) are moving via locomotion (walking, positioning), with clear bounding box tracking of their movements across the field.

Background elements (trees, spectators) appear stable; no significant fluid or gaseous motion (fire, water, smoke) observed. Ambient environmental motion is negligible.

A cyclist on a bicycle moving across the parking lot towards the left side of the frame, with motion consistent with locomotion.

No shifting background elements or fluid/environmental motion (e.g., fire, water, wind). The background (parking lines, building, parked cars, bushes) remains static throughout the frames.


A person wearing a black shirt and blue jeans stands at a white countertop, adjusting a white and silver electric knife sharpener with their hands. Three knives—two with white handles and one with a red handle—rest on the counter in front of the sharpener. The camera remains stationary, capturing the person’s hand movements as they manipulate the sharpener’s opening.

A person's arms and torso are moving while interacting with a machine, indicating discrete solid-object motion from explicit physical action (e.g., manipulating controls).

Background elements (table, stacked items, tools) are static with no shifting or environmental fluid motion (fire, water, smoke, wind) observed.


In a dimly lit indoor space with red and orange lighting, a person holding a microphone interacts with others near red curtains. The camera pans slightly and shakes, capturing movements of multiple people in the background as the central figure gestures and speaks. The scene remains dynamic with the camera shifting focus between the central figure and surrounding individuals.

A person in the foreground is moving their arm holding a hairdryer, directed towards a seated person in the background. The hairdryer and arm motion are the primary discrete object movements.

Background walls (red/orange) are static and do not shift uniformly. No ambient environmental motion (fire, water, wind, smoke) detected.


The video opens with a stationary shot of a room featuring a chair and a table. A person wearing dark shorts enters, carrying a baby dressed in light blue clothing. The person sits on the chair, holding the baby in their lap; the baby moves their arms. The camera remains static throughout, capturing the interaction against a plain wall with a visible power outlet.

Two discrete objects: an adult person moving from standing to sitting on a chair and a child being held who moves independently (kicking legs, moving arms).

The background (white wall, chair, table) is static and shows no ambient environmental motion (no fire, water, smoke, wind).


A person uses their fingers to gently pull their upper eyelid open, revealing the eye, then removes a clear circular contact lens from the eye, holding it between their fingers. A bright light source illuminates the eye area from the front. The background features a bed with patterned fabric. The camera maintains a close-up perspective, focusing on the eye and hand movements with minimal motion.

A hand and contact lens are moving: the hand manipulates the lens, positioning it into the eye, with minimal motion after placement.

The background (bed and patterned fabric) shows no shifting or environmental motion; no fire, water, or wind effects are present, confirming no ambient environmental motion.


A hand holds a blue and yellow bubble gun with a yellow nozzle, placing it on a green base before lifting the gun upward to spray a stream of bubbles against a light background. The camera remains stationary, focusing closely on the motion of the gun and the bubble emission.

The background elements (booths, tables, windows) remain static and consistent across frames, with no fluid/environmental motion (fire, water, smoke, wind) present.


A bright light source appears, transitioning to a red circular object held in close view. The light dims, revealing a dark interior with indistinct shapes within the red circle. The camera maintains a close-up perspective with subtle movement throughout.

Solid, distinct marbles are moving within a red container; their motion appears to be due to physical interactions (e.g., rolling, bouncing) within the confined space.

The background consists of a static fabric pattern with no significant shifting or fluid motion (e.g., fire, water, wind). The red container holding marbles remains consistent in position, with no environmental disturbances.


RAW CAPTION: Got it, let's tackle this caption. First, the video shows a man. He's wearing a blue and white towel around his neck, maybe a sleeveless top. He's outdoors, with buildings and trees in the background. The actions: he starts with arms out, then raises one arm up, then the other, and then lowers them. Wait, the frames go from 0 to 5 seconds. Let's check each frame. At 0, arms are out. Then he raises one arm (right?), then both up, then maybe one down. Wait, the sequence: first frame he has arms out, then raises right arm up, then both up, then maybe left arm up? Wait, the description says "arm movements". So he's making celebratory gestures. Let's list the actions in order.

He starts with arms extended to sides, then raises right arm up (punching motion?), then both arms up, then maybe one down. Wait, the video: frame 0: arms out, frame 1: right arm up, frame 2: both arms up, frame 3: right arm up, frame 4: right arm up, frame 5: arm down. Wait, the movement is sequential. So the man is performing arm movements: extending arms, raising one, then both, then perhaps a fist pump. His appearance: male, blue and white towel, sleeveless, maybe cap? Wait, the first frame shows a cap. Background: buildings, trees, clear sky. Minimal background. Camera: seems to be a handheld shot, maybe slight shake. The caption needs to be chronological.

Let's structure it: A man with a blue and white towel around his neck stands outdoors. He extends his arms outward, then raises his right arm upward, followed by both arms upward, and then lowers his right arm. He is positioned in front of buildings and trees. The camera maintains a slight shake throughout, capturing the motion from a close, eye-level perspective.

Wait, check rules: a) motion chronologically. So start with initial pose: arms out. Then first movement: right arm up. Then both up. Then maybe lowering. But in the frames: 0: arms out. 1: right arm up. 2: both up. 3: right arm up. 4: right arm up. 5: arm down. Wait, maybe it's a continuous motion. Let's see: from frame 0 to 1: right arm raises. Then frame 2: both arms up. Frame 3: right arm up. Frame 4: right arm up. Frame 5: arm down. Hmm, maybe the main actions are arm movements: starting with arms out, then raising arms up (possibly both), then maybe one arm down.

But the key is to describe the motion in order. Let's say:

A man wearing a blue and white towel around his neck stands outdoors, facing the camera. He begins with arms extended outward, then raises his right arm upward, followed by raising both arms high above his head, and finally lowers his right arm. The background includes buildings and trees, but is not the focus. The camera remains relatively close, with a slight shake, capturing the man's gestures from a frontal perspective.

Check rules: a) motion chronologically. Yes, the actions in order. b) appearance: man, blue and white towel. Number: one man. c) spatial: in front of buildings and trees (but minimal background, so maybe just "outdoors"). d) camera: close, slight shake, frontal. e) background minimal. f) exclude text, etc.

Wait, the output format must be inside <caption_output> tags. Let's make sure it's concise. Let's draft:

A man with a blue and white towel around his neck performs arm movements outdoors: he starts with arms extended, raises his right arm upward, then lifts both arms high, and lowers his right arm. He stands in front of buildings and trees. The camera maintains a close, slightly shaky perspective throughout.

Wait, check chronological order. The sequence is arms out → right arm up → both up → right arm down? Wait, in the frames:

[0] arms out (left and right arms extended)

[1] right arm up (left arm down?)

[2] both arms up

[3] right arm up (maybe left arm down?)

[4] right arm up

[5] arm down (left arm?)

Wait, maybe the key motions are: starts with arms out, then right arm up, then both up, then right arm up again, then down. But the main points are the arm raises. Let's focus on the significant movements. So the man alternates between arm positions: out, right up, both up, right up, then down. But the caption needs to be

A man is performing deliberate dance movements, including arm raises, fist pumps, and drinking motions, with clear locomotion of his body and limbs.

Background elements (buildings, trees, sky) remain stationary with no fluid motion (fire, water, smoke) or significant wind effects; trees show minimal natural sway but are not dominant.


RAW CAPTION: Okay, let's tackle this video captioning task. The user wants a concise chronological paragraph focusing on the main subjects' motions and behaviors.

First, I need to observe the video frames. The first frame shows a man in a black t-shirt walking towards a hay bale target. There's another person in a blue shirt on the left. The hay bale has red marks. The camera seems to follow the man in black.

In the next frames, the man in black is holding an axe, preparing to throw. The person in blue is nearby, maybe holding another axe. The man turns and throws the axe towards the hay bale. The camera stays focused on his action, maybe panning slightly to follow the throw.

I need to mention the key elements: the two men, their actions (walking, throwing), the hay bale as the target. Keep the background minimal. Avoid any text recognition or character names. Check the rules: chronological order, mention appearance (colors), spatial relationships (left, right), camera perspective.

Wait, the rules say "briefly describe their appearance and number (color, size, orientation)." So for the main subjects: man in black t-shirt, man in blue shirt. Their actions: walking towards hay bale, then throwing axe. The blue-shirted person is to the left, maybe holding another axe. The camera follows the main subject's movement.

Also, conclude with camera perspective. The camera seems to stay at eye level, maybe a slight pan to follow the throw. The background is the hay bale and grass, but minimal.

Check the output format: must be in <caption_output> tags, no reasoning. Let me structure it step by step.

Start with the first action: Man in black t-shirt walks toward hay bale. Then the blue-shirted person appears on the left. Then the man turns and throws the axe. The axe hits the target. Camera follows his movement, stays steady.

Wait, in the frames, it's a short sequence. Let me check each frame.

Frame 0: Man in black t-shirt walking towards hay bale. Another person's arm is visible on the left.

Frame 1: Same man, now moving towards the right. The person in blue is more visible, holding a tool.

Frame 2: The person in blue is holding a wooden stick, maybe a handle for the axe. The man in black is still walking.

Frame 3: The man in black turns, holding an axe. The person in blue is standing to his left.

Frame 4: The man in black is preparing to throw the axe towards the hay bale. The person in blue is still on the left.

Frame 5: The man has thrown the axe. The axe is in mid-air. The person in blue is watching.

So the sequence is: man in black walks toward hay bale, person in blue is on left, man turns to throw axe, axe is thrown.

Need to mention the order: starts with walking, then throwing. The two men, their colors. The axe is thrown towards the hay bale.

Camera perspective: starts with a side view, follows the man's movement as he walks and throws.

Check the rules: exclude text recognition (so don't mention the text on the shirt), exclude named characters. So describe the shirt colors: black and blue.

Mention spatial relationships: the blue-shirted person is to the left of the black-shirted man.

Background: hay bale target, grass field. But keep background minimal, so maybe just "hay bale target" as essential.

Wait, the rules say "background descriptions minimal unless essential for understanding motion." The hay bale is the target, so essential for understanding the motion (throwing at it).

So the caption should have:

A man in a black T-shirt walks toward a hay bale target, with another person in a blue shirt standing to his left. The man turns and throws an axe toward the hay bale, while the blue-shirted person observes. The camera follows the man's movement with a slight pan to the right as he throws.

Check if it's chronological. Yes, walking, then throwing.

Check appearance: black and blue shirts. Number: two people.

Spatial: blue-shirted person to the left.

Camera: follows movement, slight pan.

Make sure to exclude text on shirts, so just "black T-shirt" and "blue shirt".

Avoid "throwing an axe" if it's not clear. Wait, the person in the black shirt is holding an axe. So "throws an axe".

Wait, the video shows him preparing to throw, then the axe is in mid-air. So "throws an axe" is correct.

Let me check the output format again. It must be a paragraph in the tags. Keep it concise.

Possible caption:

A man in a black T-shirt walks toward a hay b


A girl in a light blue shirt and dark pants sits on a carpeted floor, facing forward, with a television visible to her left. A boy in a striped shirt stands behind her near a doorway. The boy walks toward the girl, who then stands up and moves toward the camera, facing it directly. The camera tilts downward and shakes slightly as it follows the girl’s movement toward the foreground.

A child (sitting on the floor, then standing) and an adult (walking toward and assisting the child) are moving due to explicit locomotion and interaction.

The background elements (walls, furniture, TV) show no uniform shifting across frames, and there are no fluid/environmental motions like fire, water, or wind present.


RAW CAPTION: Got it, let's break this down. First, the video starts with a scene of a backyard. There's a small shed, some people, and various tools. The main subjects are the people moving around. Let's check the timestamps.

At 0.0 seconds, there's a shed with two people near it—wait, the first frame shows two people standing by the shed. Then, at 1.0 seconds, another person enters the scene from the right. Then in 2.0 seconds, a fourth person (wearing blue) bends down to pick something up. Then at 3.0 seconds, the person in blue is still crouching, and others are moving. The two people from the beginning are now closer to the shed.

Wait, need to track their movements chronologically. Let's list the actions:

- Initial scene: Two people near the shed (maybe one in striped shirt, one in dark shirt? Wait, in the first frame, two people are by the shed. Then the third person (in blue) comes into view, bends down. Then the fourth person (striped shirt?) moves towards the shed.

Wait, the frames are:

[0.0] Two people standing by the shed, one in striped shirt, one in dark shirt.

[1.0] Same as 0.0, but maybe they're still there.

[1.4] Hmm, maybe the description is about motion. Wait, the video starts with two people at the shed, then a third person (blue shirt) enters from the right, bends down to pick up something from a toolbox. Then the two people move towards the shed, and the third person is crouching. Then the fourth person (striped shirt?) is moving away.

Wait, the problem says "chronological paragraph describing the provided video". Let's parse each frame:

Frame 0: two people near the shed (one in striped shirt, one in dark shirt), grassy yard, shed, tools.

Frame 1: same as 0.0, maybe a slight shift.

Frame 2: The person in blue (now crouching) is picking up something, others move. Wait, the description says "at 2.5 seconds" the person in blue is crouching, others move.

Wait, the key actions:

- People are in the backyard. Two people (striped shirt and dark shirt) are by the shed. Then a third person (blue shirt) enters the scene and crouches down to handle an object (maybe from a toolbox). Then another person (striped shirt?) moves towards the shed. Then the first two people (striped and dark) move towards the shed, and the person in blue is still crouching.

So chronological order:

1. The video begins with two people (one in a striped shirt and one in a dark shirt) standing near a small beige shed with an open door, surrounded by grass, tools, and other structures. A person in a blue shirt then enters the frame from the right and crouches down to handle an object from a toolbox on the ground.

Wait, the first frame (0.0) shows two people (striped and dark) by the shed. Then the person in blue (from the right) moves in and crouches. Then the two people move towards the shed. The person in blue is still crouching, and others are moving around.

Let me check the exact frames:

At [0.0], two people are by the shed. At [1.4], maybe the same. At [2.5], a person in blue (crouching) is near the toolbox, others move. The two people from the shed area walk towards the person in blue.

So the order is:

- Two people (one in striped shirt, one in dark shirt) stand near a beige shed with an open door.

- A person in a blue shirt enters from the right and crouches to pick up an item from a toolbox.

- The two people move towards the person in blue.

- The person in blue remains crouched, while the other two people approach the shed.

Also, spatial relationships: the shed is central, with grass around. The person in blue is near the toolbox on the ground (to the right of the shed? Maybe in the foreground).

Camera perspective: the video is shot from a fixed, top-down perspective (since it's a wide shot of the yard). No camera movement described.

Now, applying rules:

a) Motion: People move from the shed area to the toolbox area. The person in blue is crouching.

b) Appearance: Two people (striped shirt, dark shirt), person in blue.

c) Spatial: Person in blue is near the toolbox (front of the shed? The shed is in the middle

Two to three people are walking and moving around the yard, with locomotion (walking) as their motion source.

The background (shed, house, trees) is static and not shifting uniformly. There are no fluid or wind-driven motions (fire, water, smoke) observed.


A person in dark clothing reclines with an extended arm; a second individual in a white shirt approaches, positions their hands on the arm, and moves them along the limb while adjusting the arm’s position. The reclining person remains still throughout. The camera captures the interaction in a close-up, slightly shaky perspective.

Two people are visible: one person (lying down, arm extended) and another person (in white) applying a bandage. The moving objects are the hands of the person applying the bandage and the arm being bandaged, indicating manual interaction.

The background (walls, cabinet) shows no shifting or uniform movement. No fire, water, smoke, or wind motion detected.


A person in dark clothing enters from the top of a narrow brick-walled alley, walks downward while holding a dark object, bends to place it near a blue wheeled bin on the left, then exits toward the top of the frame. The camera remains static in a top-down position.

A person enters the frame, drops an object (likely shoes), bends to adjust the object, then exits. The shoes are physically manipulated by the person.

Static brick walls and parked car remain fixed; no fluid/environmental motion (fire, water, wind) observed.


A man wearing a dark shirt and blue jeans adjusts a large white panel outside a house, lifting and repositioning it while leaning over the structure. The camera remains stationary, capturing the action in front of the house's white siding and bushes.

A person in blue jeans and a dark shirt is manipulating a large structure (possibly a wall or panel) using their hands, with movements limited to torso and arm motion while working.

The background elements (house, trees, ground) remain static with no uniform shifting or fluid motion (e.g., fire, water, wind). No environmental phenomena dominate the scene.


A floorball match unfolds on a red indoor court as multiple players in dark and light jerseys actively move. Initially clustered near the goal, they disperse as some run toward the center while others pursue the puck, passing it between teammates. The camera provides a high-angle view, panning slightly to follow the players' dynamic interactions across the court.

Players (humanoids) and a ball exhibit discrete motion: running, passing, and shooting. Ball trajectory shows clear collision dynamics with players and the goal.

Background elements (walls, court lines, goal) remain stationary throughout; no fluid motion (fire, water, smoke) or wind effects observed. Background is stable with no uniform shifting.


RAW CAPTION: Got it, let's break this down. The video shows a person doing a shot put or discus throw, maybe? Wait, in the frames, the person is in a netted area, which is typical for shot put. Let's see the sequence: first, the person is holding the shot put, then spins around, releases it. Wait, the frames: [0.0] they start, maybe in the throwing circle. Then [1.2] they move, [2.2] they spin, [3.2] they release, [4.2] they step back. So the main subject is a woman (red top, black shorts) in a throwing circle. She's spinning, then releases the shot put. The net is around her, so it's a throwing cage. Background has a grassy field, building, maybe. The umbrella is on the right, but it's part of the scene but not the main action. So chronological: she holds the shot put, spins, releases, then stands. Appearance: red sleeveless top, black shorts, dark shoes. Spatial: netted area, so the cage is around her. Camera perspective: probably fixed, since it's a still frame sequence. Wait, the video is a series of frames, so camera is stationary. Let's check the rules: concise, chronological, motion. So start with her position, action. Let's structure:

A woman in a red sleeveless top, black shorts, and dark shoes stands in a circular throwing area enclosed by a net. She begins by holding a shot put, then spins in a circular motion, releases the object, and steps backward to stand still. An umbrella with colorful panels is visible to her right. The camera maintains a fixed perspective from outside the net, capturing the action within the enclosure.

Wait, check the rules: focus on motion and behavior. So the main action: spinning, releasing. Background minimal. Let's make it concise. Let's see the exact frames: frame 0 she's holding it, frame 1 she's in motion, frame 2 spinning, frame 3 releasing (since she's in a position that looks like she's let go), frame 4 she's standing. So steps: prepares, spins, releases, then stands.

So: A female athlete in a red sleeveless top and black shorts stands in a circular throwing area within a netted enclosure. She spins counterclockwise, releases a shot put, then steps back to stand still. A colorful umbrella is positioned to her right. The camera remains stationary, observing the sequence from an external angle.

Wait, need to check if the umbrella is part of the main scene. The rule says minimal background. Maybe mention it but not focus. The main subject is the athlete.

Also, in the frames, the net is around her, so the enclosure. The background is a grassy field and building, but minimal. So the caption should mention the netted area as part of the setting.

Putting it all together:

A woman in a red sleeveless top and black shorts stands in a netted throwing circle. She spins in a circular motion, releases a shot put, then steps back to stand still. A colorful umbrella is visible to her right. The camera captures the sequence from a fixed external perspective.

Wait, check if "shot put" is correct. The object is probably a shot put, but maybe the problem doesn't specify. But the action is throwing, so spin and release is typical for shot put. Let's go with that.

Make sure it's chronological: start, spin, release, stand.

Yes. Now check the output format: <caption_output>...<caption_output>

So the final caption should be concise, following the rules. Let's check the rules again:

a) Focus on motion and behavior in order. So the athlete's actions: stands, spins, releases, steps back.

b) Mention appearance: red sleeveless top, black shorts, dark shoes (but maybe shoes are not necessary, but the description says color, size, orientation. The shoes are dark, but maybe just "dark shoes" or omit if not critical. Wait, the initial frame: the athlete is wearing a red top, black shorts, and dark shoes. But the rules say "briefly describe their appearance and number". So red top, black shorts, dark shoes.

c) Spatial: netted area, umbrella to her right.

d) Camera perspective: fixed external.

e) Background minimal: maybe just mention the enclosure.

f) Exclude text, names, stylistic.

So:

A female athlete in a red sleeveless top, black shorts, and dark shoes stands in a netted throwing circle. She spins in a counterclockwise motion, releases a shot put, then steps back to stand still. A colorful umbrella is visible to her right. The camera maintains a fixed

The athlete (in red top and black shorts) exhibits distinct locomotive motion: walking, spinning, and preparing for a throw. This solid, discrete object moves due to explicit physical forces (her own body mechanics).

The background (building, grass, fence, and stationary umbrella) shows no shifting or fluid motion. No fire, water, smoke, or wind effects dominate the scene; all background elements remain static.


A man in a white tank top and dark shorts sits in a chair, strumming a large stringed instrument with rhythmic hand movements. He remains seated in a room with a red patterned curtain in the background. The camera is static, positioned through a doorway, with a slight shake.

A man moves from a seated position to standing and walking. The child remains seated.

The background (curtain, wall, floor) is static. No environmental motions (fire, water, wind) are observed.


Three individuals stand on a stage; the central figure, wearing a dark jacket and pants, holds an orange folder and speaks while occasionally glancing at it. To the left, a person in a white shirt and black pants remains stationary, while to the right, another individual in a black shirt and light pants adjusts a musical instrument, moving their hands. The camera captures the scene from an audience perspective, showing the stage with dark curtains and seated viewers in the foreground.

Three performers: central person (speaking/gesturing with red paper), right person (playing keyboard with hand movements), and left person (standing with minimal movement). Audience heads show minimal motion.

Background curtains are static; no fire, water, smoke, or wind motion observed. Audience heads are static or only minimally moving (blinking, slight head turns), which is not dominant ambient motion.


A person in a white shirt with a purple star pours liquid from a container into a glass held by another person wearing a white hoodie. The first person steps back and exits the frame, leaving the second person to look around before standing and walking away from the table. The background shows a kitchen with wooden cabinets. The camera remains stationary.

The woman in the white hoodie moves her hand and then stands up to walk away from the table. The other woman pours contents from a container into a tray.

No shifting backgrounds or fluid/environmental motion (fire, water, wind) observed. Background (kitchen cabinets, microwave) remains stationary.


A person in a red shirt with colorful bracelets styles the dark hair of a seated individual. The standing person uses both hands to manipulate the hair, adjusting and moving it upward and around the seated person’s head, while the seated individual’s head remains tilted downward. The background includes a blue wall and a bright ceiling light. The camera is fixed at a low angle.

Two people: the person in red is moving their hands and upper body to interact with the person in black, who is mostly stationary. The motion is due to physical forces (muscle movements).

The background (blue wall, framed pictures) remains stationary. No fluid or environmental motion (fire, water, smoke, wind) is observed.


A person in a black shirt and dark pants sits on the floor, holding a brass trombone and adjusting its slide while seated in front of a white door. Another individual in dark clothing walks past from the left side of the frame. The seated person continues manipulating the trombone, moving it up and down. The camera remains in a low-angle position with slight movement.

Two distinct solid objects (people) exhibit motion: seated individual playing trombone with hand/instrument movements, and standing individual walking across frame (left to right) with locomotion.

Background elements (door, walls) remain static with no shifting or fluid motion. No fire, water, smoke, or wind present; ambient environmental conditions are absent.


A woman with dark hair, wearing a black vest over a patterned shirt, sits on a concrete path. Two small white dogs with brown ears sit in front of her, one to her left and one to her right. She holds a small bottle in her right hand, extending it toward the dogs as they lean forward to interact with her, appearing to drink from the bottle. The camera remains stationary but slightly shaky, capturing the scene at eye level with minimal background details visible.

Person and two dogs exhibit subtle movements (e.g., head adjustments, slight postural shifts) consistent with natural interaction.

Static background elements (fence, grass, sidewalk) show no uniform shifting or fluid motion; no fire, water, smoke, or wind dominance.


The video opens with a wide shot of a snowy ski slope where multiple skiers and snowboarders descend, accompanied by green ski lift poles with yellow bases and moving chairs. As the camera advances forward and slightly tilts upward, it focuses on approaching a single ascending ski lift chair, while the slope below remains active with skiers gliding down. The camera maintains a steady forward motion throughout.


A person in a black hooded coat pushes a metal shopping cart filled with large blue plastic bags through a snow-covered parking lot, moving forward between parked cars. Gray and silver vehicles line both sides of the path, while other individuals walk near the lot’s edge in the background. The camera follows the person’s movement, maintaining a steady perspective as they navigate the snowy terrain.

A person is pushing a shopping cart filled with blue bags; the cart and person move steadily through the parking lot. The person's locomotion and cart movement are distinct solid-object motions.

The snowy environment shows light snowfall, but background elements (cars, distant figures) are stable with no uniform shifting. Snowfall is minimal and not dominant.


A shirtless man in dark shorts performs a drill on a blue mat in an indoor gym, keeping his legs apart throughout. He begins crouched, leaps upward, executes a cartwheel-like maneuver, and lands seated on the mat. Another man in a white tank top and dark shorts stands nearby, observing. The camera remains stationary, capturing the sequence from a fixed eye-level perspective.

A single gymnast (solid object) moves on a blue mat: performing handstands, rolling, and transitioning between poses. Motion is driven by physical forces (locomotion, collisions with the mat).

The gym background (walls, equipment, ceiling) shows no uniform shifting motion. No fire, water, smoke, or wind effects are present; environmental elements are static.
