A barefoot girl in a white shirt and pink shorts pushes a red lawnmower across a grassy yard, moving in a circular pattern near a garden with dense green bushes and a lattice fence. The camera follows her motion with slight hand-held shake, maintaining a medium shot perspective.

The girl and the lawnmower are the discrete objects moving. The girl is pushing the lawnmower across the grass.

The background (house wall and bushes) is mostly static. No significant fluid/environmental motion (fire, water, smoke, or dominant wind) is present; the movement of bushes is minimal and not dominant.


A person swims steadily in a pool, moving forward with rhythmic strokes through the water. The camera follows closely, panning slightly to reveal the blue pool edge and distant structures as the swimmer progresses toward the far end of the pool.

A dog is swimming in the pool, moving from left to right with splashes.

The background (fence, buildings) is static. Water motion is caused by the dog's swimming and is secondary; it is not the dominant motion (which is the dog's movement).


A hand holds a small, round watch with a white dial and silver case, slightly rotating it to display the face. A gloved hand enters from the right, briefly touching the watch, before the original hand adjusts its position to show different angles. The camera maintains a close-up, steady perspective throughout.

A human hand is holding a watch, with slight motion of the hand adjusting the position.

Background elements (laptop, papers) are static; no fluid or environmental motion present.


Two individuals walk onto a blue platform; the first wears purple pants and white shoes with blue accents, followed by another in beige pants and black shoes. Their feet move in sequence, stepping forward on the platform, with the camera maintaining a low-angle close-up perspective that tracks their movement.

Two distinct solid objects: a person in a light purple dress with silver high heels, and a person in beige pants with black shoes. Both exhibit locomotion (walking) on the runway surface.

Dark curtain background remains static throughout; no fluid or environmental motion (fire, water, wind) detected. Runway surface is fixed and shows no significant shifting.


A person in a light gray shirt, dark pants, a cap, and sunglasses stands on a circular platform facing away, holding a shot put. They turn to face the camera, take a step forward, then move left, stepping off the platform. The background features a grassy field with trees and a red track. The camera remains stationary with a slight shake.

A single person is moving across the frame through locomotion (walking, turning), exhibiting solid object motion with clear bounding box tracking.

Background elements (trees, field, orange cone) remain static with no uniform shifting or fluid motion (e.g., fire, water, smoke, wind).


A person wearing a black T-shirt with a graphic design crouches on a grassy backyard, then stands up, leans forward, and moves closer to the camera while smiling. The background includes a wooden fence and dense greenery. The camera remains steady, transitioning from a wider shot to a close-up as the individual approaches.

A single person (man) is moving: bending down and then standing up, with head movements.

The background consists of a wooden fence and greenery which remain stationary. No significant fluid or environmental motion (fire, water, wind) is observed.


Two individuals stand in front of a large map; the person on the left gestures toward the map with their right hand, making slight hand movements, while the person on the right stands stationary, holding an object. Both wear dark formal attire, positioned with the left individual to the right of the map and the right individual to the left of the map. The camera remains static throughout the sequence.

The woman's hand is making deliberate pointing gestures, while the man remains stationary. These are discrete solid objects (human limbs) moving due to intentional locomotion/physical action.

The background (large map on the wall) shows no uniform shifting or fluid motion (e.g., no fire, water, wind). Static elements like the map and chairs remain fixed across frames, indicating no ambient environmental motion.


Top-down view shows a speckled blue-and-white bowl, small white tube, gray bottle with blue cap, and folded white cloth arranged left to right on a white surface. The scene transitions to a medium shot of a person in a striped shirt against a light blue background; the person holds their cheeks, lowers hands, looks downward, and moves their head sideways. Camera shifts from top-down to medium shot with no significant movement.

A person (solid object) is moving, including head movements and hand gestures near the face.

The background is a solid blue color with no shifting or fluid motion. No fire, water, smoke, or wind is visible.


A person with braided hair and a light-colored shirt sits behind a white disposable plate filled with orange-sauced food. They reach forward to pick up a piece of food, bring it to their mouth, and eat, repeating the motion. The plate remains centered in the foreground with the person positioned behind it. The camera stays fixed on the plate, capturing the actions from a slightly low angle.

A person's hand and arm are moving to interact with food (picking up, lifting, and consuming), exhibiting intentional physical motion consistent with discrete object physics.

Background elements (walls, door, furniture) remain static with no uniform shifting or fluid motion observed. No fire, water, smoke, or wind-driven phenomena present.


A person's hands manipulate the flippers of a brightly lit pinball machine, guiding a ball across its illuminated playfield. The machine features vibrant, colorful elements and a glowing screen, with the player positioned to the right. The camera remains stationary, capturing the interaction from a side angle in a dark environment.

A person's hand is moving (interacting with the pinball machine), and potential movement of the pinball within the machine.

Dark background with minimal visible elements; no shifting walls, fire, water, or smoke observed. Ambient motion not dominant.


RAW CAPTION: Got it, let's tackle this. First, the video shows kids on stage. Let's list the actions chronologically.

Start with [0.0], there are four kids: one in white shirt and black skirt, another in black dress, and two more in the back. Then at [1.4], they move, so the kids are walking. At [2.5], more kids join? Wait, the frames show them moving left. Let's check the positions.

First frame: center kid white shirt, black skirt; right kid black dress, left side two kids. Then in frame 2, more kids come from left? Wait, the description says "four kids" then at some point "five kids"? Wait, the video frames: [0.0] has four kids. Then [1.4] still four, but moving. [2.5] there are five kids now, with one in green/white dress (maybe? The description says a girl in a white dress with gold trim? Wait, the problem says "briefly describe appearance and number".

So chronological:

- Initially, three girls (one in white shirt/black skirt, one in black dress, and a third in white dress? Wait, no: first frame has four people: a girl in white shirt and black skirt, a girl in black dress, two others in the back (one in white top and black skirt, another in white top and black dress). Then as they move, more girls enter from the left. Let's track movements.

At 0.0: Four children on stage. A girl in white shirt and black skirt stands center, another girl in black dress with green accents is to her right. Two additional girls (one in white top and black skirt, another in white top and dark dress) stand to the left and back. The background has red, gray, and green vertical panels (flags).

At 1.4: The group moves left, with the center girl and right girl now walking towards the left side. The two girls in the back also move left. The girl in black dress is still on the right but moving left.

At 2.5: More girls enter from the left (maybe three more?), so total five? Wait, the video shows a girl in a white dress with gold trim (like a traditional dress) joins from the left. Now there are five kids on stage. They continue walking left.

At 3.5: All girls are walking left, moving across the stage. The girl in black dress is now towards the left side, and the group is moving towards the left edge.

At 4.7: The group is further left, with the girl in black dress now off-center left, and others continuing to walk left. The background panels (green, gray, red) are visible as they move.

Now, the key points: number of subjects (kids), their movement (walking left across the stage), appearance (white shirt, black skirt; black dress; other outfits), spatial relationships (initially some on left, center, right; then moving left, so the girl in black dress is on the right initially, then moves left).

Mention the camera: it's a medium shot, possibly following the movement, maybe a pan left to follow the kids as they move left. The background is the stage curtain with color panels, but minimal description.

Wait, the rules say background minimal unless essential. So just mention the stage setup if relevant to motion, but maybe not necessary. The main is the kids' movement.

Let's structure the caption:

"Four children enter from the left and center of the stage, walking leftward. A girl in a white shirt and black skirt leads, followed by a girl in a black dress with green accents to her right; two additional girls in white tops and black skirts trail behind. As they move, more children join from the left, increasing the group. The children continue walking left across the stage, maintaining their formation. The camera captures a medium shot that follows the movement slightly left, with the background consisting of vertical colored panels."

Wait, but need to be concise. Let's check the rules: chronological order, motion, appearance (color, size, orientation), spatial relationships (if relevant), camera perspective.

Let me try again:

"Five children walk leftward across the stage. Initially, three children are visible: a girl in a white shirt and black skirt (center), a girl in a black dress with green accents (right), and two girls in white tops and black skirts (left). As the video progresses, two more children enter from the left, joining the group. All children maintain a line, moving from right to left across the stage. The camera remains stationary with a medium shot, capturing the movement against a background of vertical red, white, and green panels."

Wait, the first frame has four people

Multiple people in school uniforms are moving across the stage; their motion is discrete and caused by walking/locomotion, with clear bounding box tracking of individual subjects.

The background features static colored panels (red, blue, green) with no fluid motion or environmental elements like fire, water, or wind; no uniform shifting of background elements indicating camera movement.


RAW CAPTION: Got it, let's tackle this. The video shows hands working with a blue cord. First, the hands hold the cord, one hand has a knot. Then they pull it, maybe tightening the knot. The background has a red ribbon with text, but we can ignore that per rule f. So focus on the hands and cord. Chronological: hands manipulate the blue cord, forming or adjusting a knot. The hands are in front of the red ribbon (but minimal background). Camera is close-up, probably steady. Let's structure:

Hands hold a blue cord; one hand forms a loop or knot while the other manipulates the cord. They pull the cord to tighten the knot. The hands are positioned with the cord stretched vertically, moving the knot. Background has a red ribbon but not essential. Camera is close-up, static.

Check rules: a) motion chronological—manipulating cord, making knot. b) appearance: blue cord, hands. c) spatial: hands in front, cord between. d) camera: close-up, no movement. e) background minimal. f) no text recognition. g) think internally but don't output reasoning.

Now draft: Two hands manipulate a blue cord, with one hand forming a knot while the other pulls and adjusts the cord, tightening the knot. The hands remain positioned with the cord stretched vertically, moving the knot in front of a red ribbon background. The camera maintains a close-up, static perspective.

Wait, need concise. Let's make it shorter. "A pair of hands manipulates a blue cord, forming and tightening a knot by pulling and adjusting the cord. The hands position the cord vertically, with one hand holding the knot and the other pulling the ends. The camera captures a close-up, steady view of the hands and cord against a red ribbon backdrop." Wait, but background should be minimal. Rule e says minimal unless essential. The ribbon is in the background but maybe not essential. Wait, the ribbon is part of the background but maybe it's not necessary for understanding motion. Let's see the video: the hands are working with the cord, the ribbon is behind. But maybe the ribbon is a prop, but the caption should focus on motion. So maybe "Two hands hold a blue cord, forming a knot by pulling and tightening it. The hands move the cord vertically, adjusting the knot. The camera is a steady close-up of the hands and cord."

Check rules: a) motion chronological—form knot, pull, adjust. b) appearance: blue cord, hands. c) spatial: hands in front, cord vertical. d) camera: close-up, static. e) background minimal—maybe not needed, but the ribbon is there. But rule e says "minimal unless essential". The ribbon is part of the background, but if it's not essential for understanding the motion (which is the hands and cord), then we can mention it minimally. Wait, the problem says "exclude text recognition", so the text on the ribbon is not to be mentioned, but the ribbon's color might be relevant. Wait, the rule says "background descriptions minimal unless essential for understanding motion". So the ribbon is a background element, but the main action is hands and cord. So maybe "Two hands manipulate a blue cord, forming and tightening a knot by pulling and adjusting the cord. The hands move the cord vertically, with the cord positioned in front of a red ribbon. The camera provides a close-up, static view of the hands and cord."

But need concise. Let's try:

Two hands work with a blue cord, forming a knot by pulling and adjusting the ends; one hand holds the knot while the other pulls the cord to tighten it. The hands position the cord vertically against a red ribbon backdrop. The camera captures a steady close-up of the hands and cord.

Wait, the video starts with hands holding the cord, then manipulating. Let's check the frames: first frame, hands holding the cord with a knot. Then they pull, so maybe forming a slip knot. The motion is making a knot, pulling to tighten.

So: A pair of hands manipulates a blue cord, forming a knot by looping and pulling the cord. One hand holds the knot while the other pulls the cord ends to tighten it. The hands move the cord vertically, keeping it in front of a red ribbon. The camera is a close-up, static shot.

Check for conciseness. Maybe shorten: Two hands manipulate a blue cord, forming and tightening a knot by pulling and adjusting the ends. The hands position the cord vertically, with one hand holding the knot and the other pulling the cord. The camera remains a steady close-up of the hands and cord.

Yes, that's better. Let's check all rules. a) motion: forming knot, tightening. Chronological order. b) appearance: blue cord, hands. c) spatial: hands position cord vertically

Hands are manipulating a black wire, demonstrating discrete solid object motion through physical interaction (pulling, positioning the wire).

The background features a static red tape with text; no shifting backgrounds or fluid/environmental motion (fire, water, wind) observed.


RAW CAPTION: Got it, let's break this down. First, the main subject is a person in a gym lifting a barbell. Let's check the sequence.

At the start (0.0s), the person is in a squat position with the barbell on their shoulders. Then, they lower the barbell to the ground (0.2s to 0.4s), bending down. Then they might be resetting or preparing for the next lift? Wait, the frames go from 0 to 4.7s.

Wait, the video shows a man in black shirt and pants lifting a barbell. He starts with the barbell on his shoulders, then lowers it to the ground, bending forward. Then he's holding it on the ground, maybe preparing to lift again? But the description says "chronological order."

Let's note the motion: initial position (squat with barbell), then lowering the barbell down, bending at the hips, then standing up? Wait, no, the frames show:

[0.0] - man in black, barbell on shoulders, squatting.

[1.4] - barbell is now lower, he's still moving. Wait, the sequence:

At 0.0: man has barbell on shoulders, squatting (weight lifted).

At 1.4: he's in the process of lowering the barbell, then at 2.5: he's bent over, barbell on the ground. Wait, no:

Wait the video frames:

Frame 0: man is in a squat position with barbell on shoulders. Then, he starts to lower the barbell down. By frame 1.4, he's in a position where he's dropping the barbell. Then frame 2.5, he's bent over with the barbell on the ground. Frame 3.6: he's still bending down, barbell on floor. Frame 4.7: he's in a deep squat with barbell on floor, preparing to lift again? Wait, no, the description says "lift the barbell," but the video shows him lowering it to the ground.

Wait, the main action: he's performing a weightlifting movement, probably a deadlift. Let's see:

Start: barbell on shoulders, squat. Then lowers it down, bending at the hips, so the barbell goes from shoulders to the ground. Then he might be resetting. Wait, in frame 0.0: barbell on shoulders, man in squat. Then frame 1.4: he's dropping the barbell, moving it downward. Frame 2.5: barbell is on the ground, he's bending over. Frame 3.6: still bending, barbell on floor. Frame 4.7: he's in a deeper squat with barbell on floor, maybe preparing to lift it again? Wait, but the question is to describe the motion.

Wait, let's list the steps:

1. Man (wearing black shirt and dark pants) is in a gym, lifting a barbell. Initially, he holds the barbell on his shoulders in a squat position.

2. He lowers the barbell to the ground, bending forward at the hips, bringing the barbell down.

3. By the later frames, he is bent over, holding the barbell on the ground, possibly preparing for the next lift.

Now, spatial relationships: the gym has equipment in the background. There's another person in a white shirt taking photos (or filming) to the left, and a person sitting on a bench to the right.

But according to rules, background should be minimal unless essential. So mention the other people if relevant.

Main subject: man in black shirt, dark pants, lifting barbell (which is large, with weights).

Chronological order:

- Begins in a squat position with barbell on shoulders.

- Lowers barbell to the ground, bending forward.

- Ends in a bent-over position with barbell on the floor.

Other details: camera is static (no movement mentioned), top-down? No, it's a gym, so likely eye-level, static.

Wait, the camera perspective: the video seems to be shot from a fixed angle, no pan or move.

Now, structure the caption:

A man in a black shirt and dark pants lifts a barbell from a squat position, lowering it to the ground while bending forward, then holds the barbell on the floor in a bent-over stance. To the left, another person in a white shirt films the action, and a seated individual in a pink shirt is visible to the right. The camera remains static, capturing the sequence in a gym setting with minimal background detail.

Check rules:

a) Motion: chronological order: lifting (squat), lowering to ground, bent over.

b) Appearance: man in black shirt/pants, bar

A person is lifting and lowering a barbell through discrete physical movements (lifting, bending, lowering), with the barbell as a solid object undergoing force-induced motion.

The gym background (walls, equipment, floor) shows no uniform shifting or fluid motion; no fire, water, or wind effects are present.


A shirtless boy extends his arm toward another shirtless boy seated in a green chair at a white table; they interact with scattered cards and chips, exchanging hand gestures before the standing boy picks up a stack of chips while the seated boy adjusts them. The camera remains steady, capturing their actions from a frontal perspective with minimal movement.

The child and adult are moving their hands to interact with chips and cards on the table. The child is picking up and moving chips, and the adult is reaching to the table. The cat in the background walks away.

The background (fence, railing, table) is static with no fluid or wind-driven motion. No fire, water, or smoke observed. A cat is present but its movement is discrete and not dominant.


A pair of hands pours dark red raspberries from a white bowl into a blender containing yellow and orange fruit pieces, secures a black lid on the blender, operates it to mix into a pinkish-red liquid, then transfers the blended juice into a clear glass. The wooden cutting board with a glass of water and metal measuring cup remains to the left of the blender. Shot from a top-down perspective with no camera movement.

Discrete solid objects moving: the bowl of berries being poured into the blender, the glass of water being poured, and the blender blades mixing the contents. The hands are also moving to operate the blender.

The background (wooden cutting board and countertop) is static. No fire, water, smoke, or wind is present as dominant motion.


A person wearing a dark patterned shirt and pink tie assembles a jigsaw puzzle at a table. Their hands place a purple puzzle piece into the central image, then move to the right to select another piece from the scattered, multicolored fragments surrounding the partially completed puzzle. The camera remains stationary in a top-down perspective, capturing the workspace and the person’s hand movements. The background features a white cabinet and chair, but focus stays on the puzzle assembly.

A person's hands are moving discrete solid objects (puzzle pieces) to assemble a puzzle.

The background (table, wall, chair) shows no uniform shifting or fluid motion; no fire, water, or smoke is present.


A man wearing a black shirt stands in front of a white lat pull-down machine, extending one arm upward to grasp the bar, then pulls it down toward his chest before releasing. The camera remains static throughout, capturing the exercise motion against a gym setting with various equipment visible in the background.

A person is performing weightlifting movements (lifting a barbell overhead), with discrete motion of the arms and torso due to physical exertion.

The gym background (walls, equipment) shows no significant shifting or fluid motion. No fire, water, or smoke present.


RAW CAPTION: Got it, let's tackle this video caption. First, the main subject is a person in a gym setting, probably practicing discus or hammer throw, but looking at the red arrows on the legs, maybe it's a track and field event. The person is in mid-action, so let's see the sequence.

The video starts with the person in a lunge position, holding an object (maybe a discus), right leg forward, left leg back. Then they start moving: the arms are swinging, so the action is throwing. The red arrows point to the legs, so the motion involves the lower body. Let's check the frames: from 0 to 5 seconds, the person goes from the initial stance through the throwing motion, with the body rotating and the arm extending.

Appearance: The person is wearing a gray shirt, dark shorts, white shoes, black socks. There's a net in the background, so it's an indoor facility. The background has a red wall, some items on the ground (like a hat and paper), an orange bucket, and the netting.

Chronological order: The person begins in a lunge stance with the right leg forward (as per first frame), then moves the body to rotate, extending the arm to throw. The action is continuous, so the sequence is the throw motion, with the legs (noted by red arrows) showing the stance and movement.

Spatial relationships: The person is in front of the net, with the red wall to the left, the bucket to the right. The net is in the foreground, so the camera is capturing the throw from a side angle, maybe slightly elevated.

Camera perspective: Since it's a stationary shot, the camera is fixed, probably at a side angle to show the throw motion.

Background: Minimal, but necessary to mention the net and the indoor gym.

Now, structure the caption:

- Main subject: A person (male, gray shirt, dark shorts, white shoes) in an indoor gym, performing a throwing motion.
- Chronological: Starts in a lunge position, rotates body, extends arm to release the object.
- Spatial: Positioned in front of a net, with red wall to left, orange bucket to right.
- Camera: Fixed side angle, no movement.

Check rules: Focus on motion, appearance, spatial, camera. Exclude text, named characters.

Let's draft:

"A person wearing a gray shirt, dark shorts, and white sneakers performs a throwing motion indoors. Initially, they stand in a lunge position with the right leg forward, then rotate their torso and extend their arm to release an object. The individual's legs, marked by red arrows, shift during the motion. They are positioned in front of a net, with a red wall to the left and an orange bucket to the right. The camera captures the action from a fixed side angle."

Check if concise. Maybe "gray shirt" and "dark shorts" can be simplified. Also, "object" might be better as "discus" but the rules say exclude named objects if not essential. Wait, the problem says "exclude text recognition, named characters, or stylistic analysis". So the object is not named, so "object" is fine.

Wait, the video might be a discus throw, but the instruction says to exclude named objects. So better to say "an object" or "a discus" but maybe not. Let's see. The problem states: "Briefly describe their appearance and number (color, size, orientation)". The person's appearance is gray shirt, dark shorts, white sneakers.

Let me adjust:

"A person in a gray shirt, dark shorts, and white sneakers executes a throwing motion inside a gym. They begin in a lunge stance with the right leg forward, then rotate their body and extend their arm to release an object. Red arrows highlight their lower body during the movement. The individual stands in front of a net, with a red wall to the left and an orange bucket to the right. The camera maintains a fixed side-angle perspective throughout."

Check if too long. Rules say "concise". Let's tighten.

"A person wearing a gray shirt, dark shorts, and white sneakers performs a throwing motion indoors. They start in a lunge position (right leg forward), rotate their torso, and extend their arm to release an object. Red arrows indicate leg movements. Positioned in front of a net, with a red wall left and orange bucket right. The camera is fixed in a side angle."

Hmm. "Red arrows indicate leg movements" – but the problem says to mention spatial relationships if relevant. The red arrows are part of the video, so maybe they're highlighted in the video, so describe their presence.

Wait, the user says: "Focus primarily on the motion and behavior of main subjects (people/animals/objects) in chronological order." So the red arrows are part of the video,

A person (solid, distinct object) is performing repetitive motion with their arms and body, indicating physical locomotion or force application.

Background elements (red structure, green floor, orange bucket) remain stationary across all frames, showing no shifting or environmental fluid motion (fire, water, wind).


A woman with long dark hair, wearing a blue shirt and pink lipstick, holds a black and white sneaker in her right hand. She lowers the shoe from near her face to her side, then turns her head slightly to the right. The background includes a beige bed with a rumpled cover and wooden closet doors. The camera remains static, capturing her upper body and immediate surroundings.

The woman is moving her head and hand holding a shoe; these are solid objects moving due to explicit physical actions.

Static background (wooden doors, bed, chair) with no shifting or fluid/environmental motion (fire, water, wind).
