RAW CAPTION: Got it, let's tackle this captioning task. First, I need to understand the video. The video shows close-up hands playing a guitar. Let's break down the elements.

The main subject is a person's hands on a guitar neck. The hands are moving, probably fretting and strumming. Let's check the appearance: the hands are in focus, the guitar has a dark fretboard with metal frets, and the person's fingers are pressing the strings. The background is a bit blurred but has some items, maybe an amplifier or other equipment, but we need to keep background minimal.

Chronological order: the hands are shown pressing the strings, moving across the fretboard, likely strumming. The motion is repetitive, fingers moving up and down the frets.

Spatial relationships: the hands are on the guitar neck, which is horizontal in the frame. The camera is close-up, focusing on the hands and guitar neck.

Camera perspective: it's a close-up shot, probably handheld, with a slight shake? Wait, the video description says "slight shake" in the rules, but looking at the frames, maybe the camera is steady but close. Wait, the user's example says "slight shake" but in this case, the video might have a steady close-up.

Wait, the rules say: "Conclude with the camera perspective and movement (e.g., top-down, pan left, slight shake)." So need to describe that. The video is a close-up of the hands on the guitar, so camera is close-up, probably static but maybe slight movement.

Now, structure the caption:

- Start with main subject: two hands (left and right) on a guitar neck.
- Describe motion: pressing strings, moving along the fretboard.
- Appearance: hands, dark fretboard with metal frets.
- Spatial: hands on guitar neck, background blurred.
- Camera: close-up, slight shake.

Wait, the background: there's some equipment in the background, but rule e says minimal background unless essential. So maybe mention "blurred background with indistinct objects" but keep it minimal.

Let's draft:

"Two hands, light-skinned, interact with a dark guitar neck featuring metal frets. The left hand presses strings across the fretboard while the right hand strums, moving fingers rhythmically. The camera maintains a close-up perspective focused on the hands and fretboard, with slight movement, against a blurred background containing indistinct equipment."

Check rules:

a) Motion: yes, hands pressing and strumming.

b) Appearance: hands, guitar neck, metal frets.

c) Spatial: hands on guitar neck, background blurred.

d) Camera: close-up, slight movement.

e) Background minimal: blurred with indistinct equipment.

f) Exclude text, names: good.

g) Internal reasoning, but output only caption.

Let me check the video frames: the video shows hands on guitar, so the caption should reflect that. The hands are moving, pressing strings. The guitar neck is visible with frets. Camera is close-up, maybe handheld so slight shake.

Another angle: the video starts with hands on guitar, and they move. So chronological: hands press strings (left hand), right hand strums. Motion is continuous.

Final caption should be concise. Let's make it shorter.

"Close-up of two light-skinned hands playing a guitar: the left hand presses strings along the dark fretboard with metal markers, while the right hand strums rhythmically. The camera remains steady, focused on the hands and fretboard, with a blurred background."

Wait, but rule d says "conclude with camera perspective and movement". So maybe: "The camera maintains a close-up perspective, slightly shaky, focusing on the hands and fretboard."

Wait, the video description says [0.3s] to [4.7s], the hands are moving. So the motion is continuous.

Let me revise:

"Two light-skinned hands manipulate a guitar neck with a dark fretboard and metal frets. The left hand presses strings across the fretboard, while the right hand strums rhythmically. The camera stays close-up on the hands and fretboard, showing slight movement, with minimal background detail."

Check length and conciseness. Need to be chronological.

The video starts with hands on guitar, then moving. So the sequence: hands press strings, strum.

Yes.

Another check: "main subjects (people/animals/objects)" here the main subjects are hands (part of a person, but the rule says "people/animals/objects" so hands are part of the person, but we can describe the hands.

Appearance: light-skinned, number: two hands.

Spatial: on the guitar neck.

Camera: close-up, slight movement.

Background: minimal.

So the caption:

<caption_output>Two light-skinned

Discrete hands moving across guitar fretboard and strings in deliberate motion for playing music; solid, distinct objects undergoing explicit physical manipulation.

Background elements (keyboard, wall) remain static with no uniform shifting; no fire, water, smoke, or wind present.


A young child in a checkered shirt and light pants stands and walks through a room with wooden floors, passing furniture and moving toward a doorway while holding an object. The camera follows the child's movement with a slight shake, maintaining a frontal view.

A child (discrete object) is moving across the scene while holding an object, with observable locomotion and interaction with the environment.

The brick wall and furniture in the background show no uniform shifting; no fire, water, smoke, or wind-driven motion is present.


Two individuals, one in a purple tank top and black pants, the other in an orange shirt and dark shorts, begin by raising their arms and moving energetically in a room. The person in orange steps off a chair, then both dance around the space; the purple-clad individual moves to the left near the kitchen area while the orange-shirted person remains central, gesturing and shifting position. The background includes a television, curtains, and kitchen cabinets. The camera remains stationary with slight shake.

Two women are performing coordinated movements, including dancing, arm gestures, and manipulating a fabric. Their motion is distinct and tracked by bounding boxes.

The background elements (walls, curtains, TV, furniture) remain stationary throughout the video. No fluid motion (fire, water, smoke) or wind-driven environmental effects are observed.


RAW CAPTION: Got it, let's break this down. The video shows an underwater scene with sharks and a cage. First, there's a shark swimming near the cage. Then, the shark moves around, possibly interacting with the cage. The cage has people inside, so they're visible through the metal bars. The background is blue water, with light coming from above. Let's note the sequence: the shark is first in the frame, then moves towards the cage, then the cage with people is visible. The camera seems to follow the shark's movement, maybe panning or following. Need to mention the main subjects: sharks (maybe two, one prominent), the cage with people. Their motions: swimming, moving around. Spatial relationships: shark is near cage, people inside cage. Camera perspective: underwater, following the shark, so maybe moving with the shark's motion. Keep it chronological. Let's structure it:

At the start, a shark swims near a metal cage holding people. The shark moves around the cage, approaching it, then continues swimming. The people in the cage are visible through the bars. The camera follows the shark's movement, maintaining an underwater perspective with blue water as background.

Check rules: focus on motion, chronological order, appearance (shark size, color, people in cage), spatial (shark near cage), camera movement (follows shark, underwater). Avoid text recognition.

Let me draft:

A shark swims near a metal cage containing several people, moving in a circular pattern around the cage. The shark’s gray body glides through the clear blue water, occasionally passing close to the cage’s bars. The people inside the cage remain stationary, visible through the mesh. The camera follows the shark’s motion, panning slightly as it moves, maintaining an underwater perspective with light filtering from the surface.

Wait, check if it's concise. Maybe shorter. Let's see:

Sharks swim near a metal cage with people inside. A large gray shark circles the cage, passing close to it, while another shark swims nearby. The cage holds several individuals, visible through the bars as the shark moves around. The camera follows the sharks' motion underwater, with the blue water background.

Wait, the video shows maybe one prominent shark, but maybe two. Let's check the frames: first frame shows two sharks? Wait, the first frame has a shark on left, then another on right. Then the shark moves. Let's see the timestamps. The first frame: shark on left, then the next frame, the shark moves to the right, then another shark comes into view. So maybe two sharks. But need to be accurate. The caption should describe motion chronologically.

First: A large gray shark swims near a metal cage containing people, then a second shark appears. The sharks circle the cage, moving through the blue water. The people remain inside the cage, visible through the bars. The camera follows the sharks' movement underwater, capturing their motion around the cage.

Wait, but need to be concise. Let's try:

A large gray shark swims near a metal cage holding several people, moving in front of the cage and circling it. A second shark briefly appears nearby. The camera follows the sharks' motion underwater, with the blue water background.

Wait, the main subjects are the sharks and the people in the cage. The movement is chronological: shark approaches, circles, people are inside. Camera follows. Let's check the rules.

Rule a: motion and behavior chronologically. So start with shark near cage, then moves around, maybe another shark.

Rule b: appearance and number. Sharks are gray, large. People in cage.

Rule c: spatial relationships. Shark is in front of cage, circling it.

Rule d: camera perspective (underwater, following) movement (pan or follow).

Rule e: minimal background, so blue water is okay.

Let me draft a concise paragraph:

A large gray shark swims near a metal cage containing several people, moving in a circular pattern around the cage. The shark passes close to the cage’s bars, with another shark briefly visible nearby. The camera follows the first shark’s movement underwater, maintaining a perspective that captures the sharks’ motion against the blue water background.

Check if it's concise. Maybe trim "briefly visible" to "with another shark visible nearby". Wait, the video shows maybe two sharks at different times. Let's see the frames: frame 0: shark left, frame 1: shark left, another on right, frame 2: shark moves right, frame 3: shark is in front of cage, frame 4: two sharks (one in front, one below?), frame 5: shark on right. So maybe multiple shots of sharks moving around.

Let's go with:

A large gray shark swims near a metal cage with people inside, circling the cage and passing close to its

Two sharks are swimming around a stationary cage, moving due to their own locomotion.

The water environment is calm and not the dominant motion; the cage remains stationary, indicating no significant ambient environmental motion.


A person's light-skinned hands, wearing beige pants, play the keys of two keyboards: a silver Yamaha Montage X6 (with visible knobs and screen) positioned above a black keyboard, both on a stand. The hands move across the keys of both instruments, alternating between the upper and lower keyboards in sequence. The background includes a room with window blinds and a shelf with equipment. The camera remains static, providing a side view of the keyboards and hands.

The person's hands are moving on the keyboard keys, which is a discrete solid object motion due to explicit physical force (playing the instrument).

No shifting background or fluid/environmental motion (fire, water, wind) detected. Background elements (wall, equipment) are static.


A person in a white tank top manipulates clear plastic cups with "Speed Stacks" and "Pro Series 2" branding, stacking and rearranging them on a table. Their hands move cups between stacks, adjusting positions while the cups are arranged in multiple piles. The camera maintains a close perspective focused on the cups and hands, with minimal movement.

The person's hands are moving cups, which are solid objects being stacked and rearranged.

Background elements (walls, posters) are static with no fluid or environmental motion (fire, water, smoke, wind).


RAW CAPTION: Got it, let's tackle this. The video shows a person in a gym. First, check the main subject: a man. He's wearing dark clothes, maybe a black shirt and dark pants, and sneakers. He's doing a squat movement. Let's see the sequence: starts in a squat position, then stands up, maybe jumps? Wait, the frames show him crouching, then rising. Let's check the actions step by step.

Frame 0: he's in a squat, knees bent, back straight. Frame 1: still squatting, maybe adjusting. Frame 2: he's moving up, standing. Frame 3: he's in a deeper squat again? Wait, no, the video might be a sequence of him doing jump squats or something. Wait, the description says "chronological paragraph describing the provided video."

So the main subject is a man in dark athletic wear. He's performing a squat motion, possibly jumping squats. Let's outline the actions: he begins in a squat position (knees bent, torso upright), then transitions to a standing position, and repeats. The background is a gym with weight racks and a black cabinet. The camera is static? Wait, the video has a slight shake, maybe handheld. The floor is wooden, but background should be minimal.

So structure: main subject (man, dark clothes) doing squats, moving from crouched to standing, repeating. Background: gym with equipment, minimal. Camera: slight shake, static perspective? Wait, the video description says "slight shake" in the rules? Wait, the problem says "conclude with the camera perspective and movement (e.g., top-down, pan left, slight shake)." So need to mention if the camera has movement.

Looking at the frames, maybe the camera is mostly static but with a slight shake. Let's confirm. The caption needs to be chronological. So:

A man in dark athletic wear performs a squat motion, beginning in a crouched position with knees bent and torso upright, then stands to full height before returning to the squat. He repeats this sequence in a gym setting with weight racks visible in the background. The camera maintains a static perspective with minimal movement, capturing the exercise from a frontal angle.

Wait, check the rules: "Mention spatial relationships if relevant (e.g., in front of, to the left)." Here, the man is in the center of the frame. Background is gym equipment, but minimal. The main action is the squat.

Also, rules say exclude text recognition, named characters, etc. So no names.

Let me check the steps:

1. Subject: man, dark clothes (shirt, pants, sneakers). Motion: squatting, standing up, repeating.

2. Chronological order: starts crouched, stands, then crouches again, etc.

3. Background: gym with weight racks (minimal description).

4. Camera: perspective—frontal, slight shake.

So putting it all together.

Possible caption:

A man in dark athletic wear performs repeated squat movements, transitioning from a crouched position with bent knees to standing upright and back down. He is positioned centrally in the frame within a gym environment featuring weight racks in the background. The camera captures the action from a frontal perspective with minimal movement.

Wait, but "slight shake" is mentioned in the rules for camera movement. The video might have a slight shake, so need to include that.

Let me check the sample rules: "conclude with the camera perspective and movement (e.g., top-down, pan left, slight shake)."

So "camera perspective and movement" should be described. So maybe: "The camera maintains a frontal perspective with a slight shake."

Putting it all together.

Another check: appearance—color, size, orientation. The man is wearing dark (maybe black) clothes, so "dark athletic wear".

Sequence: crouched (squat), then stands up, then back to squat.

So:

A man in dark athletic wear executes a sequence of squat movements, lowering himself into a crouched position with bent knees and an upright torso, then rising to full standing before repeating the motion. He remains centered in the frame throughout the exercise, with weight racks visible in the background of the gym. The camera captures the action from a frontal perspective with a slight shake.

Wait, "slight shake" is part of the camera movement. Yes.

Is the background essential? The rules say "minimal unless essential for understanding motion." Here, weight racks are part of the gym, which is the setting, so minimal description.

Check if the motion is correct: squatting, standing up, repeating.

Yes.

Let me structure it as a paragraph.

Final caption:

A man in dark athletic wear performs a series of squat motions, beginning in a crouched position with bent knees and an upright torso, then standing fully

A person is performing jumping rope, with the rope and body moving in discrete, solid object motion due to physical forces (locomotion and rope dynamics).

The background elements (walls, gym equipment, wooden floor) remain stationary and do not shift uniformly. No fire, water, smoke, or wind is visible; the environment is static.


A person with light brown hair, wearing a black shirt and a necklace, sits in a car's passenger seat. They lean forward, then sit back, adjust their position, and look around. The camera is handheld and slightly shaky, capturing the individual's movements within the car interior.

A person (discrete solid object) is moving their hands and upper body while seated in the car, exhibiting controlled physical motion consistent with discrete object physics.

No significant shifting backgrounds or fluid/environmental motion (e.g., fire, water, smoke) observed; car interior serves as static background with no dominant ambient elements.


A person wearing a white shirt turns a large wooden wheel on a mechanical structure while seated behind it in a wooden room with other machinery visible in the background. The camera remains mostly static with minimal movement.

A person is actively turning a large wheel on a mechanical device, with their arms and upper body moving in discrete, purposeful motions.

Background elements (wooden walls, floor, chair) show no uniform shifting; no fluid/environmental motion (fire, water, smoke, wind) present.


YOUR FINAL CAPTION HERE

Discrete solid objects include a person drawing on paper, a person holding a spoon, and a hand holding a spice container. These objects move due to explicit physical actions (drawing, stirring, holding).

No significant shifting backgrounds or fluid/environmental motion (fire, water, wind) observed. Background elements (e.g., kitchen items, drawing table) remain static within each scene, with scene transitions occurring via cuts rather than continuous camera movement.


A circular tire tread depth gauge rests on a textured tire surface. A hand holds the gauge, rotating it slightly while the needle moves across the scale’s colored sections. The hand manipulates the gauge, adjusting its position, with the camera maintaining a close-up view, focusing on the gauge and hand’s motion.

The needle of the tire pressure gauge is moving in response to pressure changes. A hand is holding and slightly adjusting the gauge.

The background (tire surface) is static with no shifting; no fluids or environmental motions (fire, water, wind) are present.


Adult hands with brown sleeves manipulate a thin brown stick, threading it through a woven structure attached to a deer head, adjusting its position in front of dry grass and a blue bag with tools. The camera remains in a steady close-up, focusing on the hands' precise movements.

Two hands are manipulating solid objects (likely sticks or tools) through deliberate physical actions.

No shifting backgrounds observed; no fire, water, smoke, or significant wind motion detected in the environment.


A swimmer in a black and orange swimsuit swims through the pool in a side view, extending arms forward and pulling back with legs kicking to propel forward. The camera maintains a side perspective, following the swimmer's motion as they move along the lane.

The swimmer (a solid object) is moving through the water in a freestyle stroke, with visible arm movements and body rotation.

The background (pool edge and lane dividers) is static and does not shift uniformly. The water is a fluid medium, but the dominant motion is the swimmer, not the water flow.


RAW CAPTION: Got it, let's tackle this. First, identify the main subjects. The video has a statue in the foreground, a person in the background. Let's check the sequence.

In the first frame, the statue is in the center, wearing a helmet and camouflage, holding something. Then, the person in the background (wearing a white shirt and khaki shorts) moves. The statue is static, but the person behind it moves—maybe walking or adjusting. The camera is moving a bit, maybe panning slightly to the right, as the statue's position changes a little. Wait, the frames show the statue staying, but the person behind shifts. Background has a store with lights, but minimal details.

Rules: focus on motion chronologically. Main subjects: statue (static, but maybe slight movement? Wait, the frames show the statue's arms moving. Wait, looking at the video description: the statue is a mannequin, maybe. Wait, the video shows the statue: in frame 0, it's holding something, then in frame 1, maybe adjusting, frame 2, arms crossed, etc. Wait, the description says "statue of a man in military uniform with a helmet, holding a bottle. Behind it, a person in white shirt and khaki shorts moves."

Wait, the frames: the statue is the main subject. It's a statue (so not moving, but wait, maybe it's a mannequin? Or the video is moving. Wait, the user says "motion and behavior of main subjects". The statue might be static, but maybe the camera is panning, making the statue's position change. Wait, in the video, the camera is moving slightly to the right, so the statue is still in the frame, but the background shifts.

Wait, the steps:

- Main subjects: statue (military uniform, helmet, standing), and a person in the background (white shirt, khaki shorts).

Chronological order: the statue is initially facing forward, then the person behind it moves (walks away), and the camera moves slightly to the right.

Appearance: statue is in military attire (camouflage, helmet), person is white shirt, khaki shorts.

Spatial: statue is in the foreground, person is behind and to the left.

Camera movement: slight pan to the right, maybe a shake.

Background minimal: store interior with lights, but not essential.

So putting it together:

The video features a stationary statue of a man in camouflage military attire and a helmet, positioned in front of a store interior. Behind and to the left of the statue, a person wearing a white shirt and khaki shorts moves, adjusting their stance and walking away. The camera pans slightly to the right with minor shake, maintaining focus on the statue while the background store elements remain out of focus.

Wait, check rules. Need to focus on motion of main subjects. So the statue might be static, but maybe the person is moving. The statue's arms might move (from holding to crossing). Let's check the frames:

Frame 0: statue holding something, person behind.

Frame 1: statue's arm moves, person walks.

Frame 2: statue has arms crossed, person moves more.

So the statue's arms move (from holding to crossing), and the person behind walks.

So:

A statue of a man in camouflage military uniform and helmet, initially holding an object, then crosses its arms. Behind and to the left, a person in a white shirt and khaki shorts walks away. The camera pans slightly right with a minor shake, capturing the statue’s movements and the person’s motion against a store interior backdrop.

Wait, "capture the motion": statue’s arms move (from holding to crossed), person walks. Need to be concise.

Let me structure:

The video shows a statue in military uniform with a helmet, initially holding an object, then crossing its arms. Behind and to the left, a person in a white shirt and khaki shorts walks away. The camera pans slightly to the right with a slight shake, maintaining focus on the statue.

Wait, but the person is in the background, so "behind and to the left" of the statue.

Yes. Now, check all rules:

a) Motion and behavior in chronological order: statue (holding then crossing arms), person (walking away).

b) Appearance: statue (military uniform, helmet, camouflage), person (white shirt, khaki shorts).

c) Spatial: statue in front, person behind/left.

d) Camera: pans right, slight shake.

e) Background minimal: store interior mentioned, but not essential.

f) No text recognition.

g) Omit reasoning.

So final caption:

<caption_output>A statue in camouflage military uniform and helmet initially holds an object, then crosses its arms. Behind and to the left, a person in a white shirt and khaki shorts walks away.

Two discrete objects moving: a foreground person in military uniform making arm movements, and a background person walking from left to right.

The background (walls, shelves, ceiling) is static with no fluid or wind motion. No fire, water, or smoke visible.


A hand holding a metallic tool moves across the surface of a white cup filled with coffee featuring intricate latte art. The hand, positioned above the cup, gently guides the tool in a circular motion, modifying the swirling pattern. The cup remains stationary on a dark surface, with the background blurred and indistinct. The camera maintains a close-up, steady shot focused on the cup and the hand’s precise movements.

A human hand holding a metal tool moves over a coffee cup to create latte art; discrete movement of the tool and hand is the primary motion.

Background elements (e.g., table surface, cup) show no uniform shifting; no fire, water, or smoke-dominated motion observed.


A young girl in pink pajamas lies on a beige carpet under a dark piece of furniture, then crawls forward toward a stationary pink toy car positioned in front of her. The camera maintains a static top-down view throughout the sequence.

The baby (a person) exhibits subtle head and body movements (e.g., turning head, slight body shifts) while lying on the floor. The purple toy remains stationary.

The background elements (carpet, furniture, wall) remain static throughout the sequence with no shifting or environmental motion. No fire, water, smoke, or wind is present.


A split-screen instructional image shows a seated person performing an upper arm exercise with hands behind the head and arm raised. The scene transitions to a living room where three individuals are present: one in a blue shirt and dark pants sits on a chair to the left, another in a red shirt and dark pants sits on a chair to the right, and a man in a black shirt and gray pants stands behind them. The person in the red shirt adjusts their posture, raising their arm upward. The camera shifts from the static instructional frames to a dynamic view of the room, capturing the seated individuals and the standing person with minimal background detail.

The person in red (sitting) exhibits motion: bending forward and then returning to an upright position, which is a discrete object movement (locomotion of a person).

The background (room with furniture and walls) remains static throughout the visible frame; no ambient environmental motion (fire, water, smoke, wind) is present.


A boy wearing a blue zip-up hoodie over a light blue checkered shirt sits facing the camera, making minor head adjustments and moving his mouth as if speaking. The camera remains stationary throughout, capturing him centered against a beige wall with a framed picture and dark decorative object in the background.

The boy (a solid object) is making small intentional movements (e.g., head movements, slight body shifts) as he speaks.

The background (wall, framed picture, star decoration) is static and unchanging. No environmental fluid motion (fire, water, smoke, wind) is present.


A hand presses keys on a keyboard, fingers moving rhythmically across the black and white keys. The hand remains positioned in front of the keyboard, with the camera maintaining a steady top-down view.

The background (piano and control panel) is static; no shifting backgrounds or fluid/environmental motion (fire, water, wind) detected.


A person wearing a white chef's coat with black buttons stands behind a red countertop, using two utensils to mix a salad in a large glass bowl. The chef moves the utensils in a circular motion, occasionally lifting the bowl slightly while stirring. The background features wooden cabinets, a stove, and a sink with a vase of red flowers. The camera remains stationary, capturing the scene from a fixed medium shot angle.

The chef's hands and the bowl on the counter exhibit deliberate movement (e.g., stirring, handling food), indicating solid objects moving via explicit physical actions.

The kitchen background (cabinets, stove, vase) shows no shifting or fluid motion; no fire, water, smoke, or wind is present.


Dancers in traditional attire—men in dark vests and pants, women in white tops and patterned skirts—begin moving in a circle within an open area, surrounded by seated spectators. Additional dancers join the circle over time, performing synchronized steps and partner turns, interacting closely as they move. The camera slightly pans to follow their motion, capturing the coordinated dance and audience presence.

Multiple dancers (solid objects) performing coordinated movement with clear locomotion, spins, and interactions (e.g., dancers approaching each other, spinning, stepping).

No shifting backgrounds or fluid/environmental motion observed (trees, audience remain static). No fire, water, smoke, or wind elements present.


A shirtless man in gray shorts and black shoes holds a basketball with both hands in front of his body, then gradually lowers the ball toward his waist while standing on an outdoor basketball court with a hoop visible behind him. The camera remains stationary.

Discrete objects in motion: basketball player performing shooting motion (bending, arm extension) and basketball in flight trajectory. Both exhibit solid, distinct motion due to physical forces (muscle actuation, gravity).

Background features (trees, sky, court lines) are static with no shifting motion or fluid effects (e.g., wind, water, smoke). No ambient environmental motion is present.


A taller individual in a white sweatshirt with red and blue text adjusts their shirt, stands upright, and faces forward. A shorter individual in a white shirt enters from the right, reaching toward the taller person's arm and touching it. The camera remains static with minimal shake, capturing the interaction against a dark blue background.

Multiple people (solid objects) are moving: one individual in a white sweatshirt adjusts their clothing and shifts position, another person in a white tank top moves their arm, and a third individual enters the frame from the right. These motions are driven by human locomotion and gestures.

The background is dark and static with no shifting elements or fluid/environmental motion (e.g., fire, water, wind).


The video shows a person's hands positioned on a piano keyboard. The right hand, marked with numbered finger indicators (5, 3, 2, 1) on white keys, and the left hand are initially visible in a top-right quadrant. A hand (likely the right hand) then moves downward to press a white key on the keyboard in the bottom-left quadrant, maintaining pressure. The camera maintains a split-screen view across multiple angles of the hands and keyboard, with no significant movement between frames.

Discrete solid objects (human hands) are moving on the piano keys, indicating locomotion due to physical interaction (playing piano).

The background elements (piano keys, sheet music) are stationary; no shifting backgrounds or fluid/environmental motion (fire, water, wind) is present.


RAW CAPTION: Okay, I need to create a concise caption for this video based on the given rules. Let me start by watching the video description.

The video shows Justin Bieber solving a Rubik's cube. The text on the screen mentions "Justin Bieber Solves The Cube" and "oceanup.com". But according to the rules, I shouldn't include text recognition or named characters. So I need to ignore that part.

The main subject is a person (though the name is excluded) solving a cube. The person is wearing a black shirt and a necklace, maybe. They're in a setting with people in the background. The background has some people walking, maybe in a store or public place. There's a blue curtain and a water bottle visible.

The video starts with the person holding the cube, manipulating it. Then they twist the cube, solve it. The camera is probably static, but maybe there's a slight movement. Wait, the user says to describe camera perspective and movement. The original video might be a single shot, so maybe the camera is fixed.

I need to focus on the motion: the person is manipulating the cube, turning the faces. The cube is colorful, standard Rubik's cube. The person's hands are moving the cube around. Spatial relationships: the person is in front of a blue curtain, with a water bottle to the right. The background has people moving but not in focus.

Rules say to exclude text recognition, so no mentioning Justin Bieber. Just describe the person's actions. The caption should be chronological. So first, the person holds the cube, then twists it, solves it. The cube is in their hands, they rotate it. Background is blurred with people walking.

Let me check the rules again. a) Motion and behavior in order. b) Appearance: black shirt, necklace, cube. c) Spatial: person in front of blue curtain, water bottle to the right. d) Camera: probably static, but maybe slight shake. The original video might be a standard shot, no movement.

Wait, the user says "exclude text recognition, named characters", so no "Justin Bieber" but maybe describe the person as a young man or something. Wait, the rules say "briefly describe their appearance and number (color, size, orientation)". So maybe "a person wearing a black shirt and necklace holds a colorful Rubik's cube".

But the rules also say "exclude named characters", so even if the person is recognizable, we don't name them. So just say "a person".

So the caption should start with the person holding the cube, manipulating it, turning the faces, solving it. The cube is colorful, in their hands. Background has people moving but minimal description.

Wait, the video shows the person in the foreground, with people behind them. Maybe a few people in the background, but since it's a crowd, maybe mention "blurred figures" or "people walking".

Let me structure it:

A person wearing a black shirt and necklace manipulates a colorful Rubik's cube, twisting its faces with their hands. The individual stands in front of a blue curtain, with a water bottle visible to their right. Blurred figures move in the background. The camera remains static throughout the sequence.

Check the rules:

a) Motion in order: holding cube, twisting, solving. Yes.

b) Appearance: black shirt, necklace, colorful cube. Yes.

c) Spatial: in front of blue curtain, water bottle to the right. Yes.

d) Camera: static. Yes.

e) Background minimal: blurred figures moving. Okay.

f) Excluded text and names. Correct.

g) No internal reasoning. Just the caption.

Yes, this should work. Let me check the example output. The user's example has "A person in a black shirt and necklace holds and twists a colorful Rubik's cube, solving it while standing in front of a blue curtain. A water bottle sits to the right. Blurred figures move in the background. The camera remains static."

Wait, the user's instruction says to "keep background descriptions minimal unless essential for understanding motion". So maybe "blurred figures" is okay since it's part of the setting. The water bottle is to the right. So the caption would be:

A person in a black shirt and necklace manipulates a colorful Rubik's cube, rotating its faces. They stand in front of a blue curtain with a water bottle positioned to their right. Blurred figures move in the background. The camera maintains a static perspective throughout.

But maybe "manipulates" is better than "rotating", but "rotating" is part of the motion. Let me check the wording. The action is solving the cube, so the person is twisting the cube, solving it. So "twists the cube's faces" or "rotates the cube's sides".

Wait, the rules say "briefly describe their

The primary moving object is the Rubik's cube being manipulated by hands (explicit physical forces). Additional discrete objects include people walking outside the window (due to locomotion), but these are secondary to the cube-solving action.

The indoor background (room walls, door) is static and fixed. The outdoor background through the window shows people walking, but this is discrete locomotion (not fluid/gas-driven like fire/wind/water), so it does not trigger the Ambient Rule. Background elements do not shift uniformly.


A man in a yellow shirt and black pants bends forward to lift a large barbell with multiple weight plates in a gym; other individuals work out in the background. He strains to maintain the lift, failing to complete the movement. The camera remains static, capturing the scene from a frontal perspective with minimal movement.

A person in a yellow shirt lifts a barbell with weights, performing a squat motion; other gym patrons are visible but stationary or performing minor movements.

Static gym background (walls, windows, equipment) shows no uniform shifting or fluid/environmental motion (no fire, water, smoke, wind).


A shirtless man in blue shorts performs a half-kneeling triceps kickback exercise in a gym setting. He begins on his right knee, extending his right arm backward with a dumbbell while maintaining a stable stance. He then switches to his left knee, repeating the motion with his left arm extended backward. The background includes stacked wooden boxes and gym equipment. The camera remains stationary, capturing the man from a frontal perspective as he alternates sides during the exercise.

A person is executing a triceps kickback exercise, moving their arm and body in controlled locomotion (bending forward, extending arm). The person is a distinct, solid object moving due to explicit physical forces (muscle contraction during exercise).

The static background elements (brick walls, stacked boxes, gym equipment) show no uniform shifting or fluid motion (e.g., fire, water, smoke). No environmental elements dominate motion.


A person's hands hold a halved yellow lemon, using a small knife to slice it into wedges on a white plate with red floral patterns; the cut lemon pieces accumulate to the left as the knife moves through the fruit. The camera maintains a steady top-down view throughout the sequence.

A hand holds a half-orange while a knife cuts through the fruit, producing discrete orange segments that fall onto the tablecloth. The motion involves solid objects (hand, knife, orange) interacting through physical contact forces.

The tablecloth background shows no shifting or fluid motion. No fire, water, smoke, or wind is present, indicating no ambient environmental elements.


A man in gray clothing and white shoes lifts a barbell from the ground to chest height, standing upright in a basement gym. The camera remains stationary, capturing the motion from a fixed angle.

Static background elements (walls, ceiling, equipment) show no uniform shifting; no fire, water, smoke, or wind visible.


A man in a green T-shirt with yellow text sits on a small stool beside a man in a blue and white striped shirt on a sidewalk near a corrugated metal structure. People walk past them, including a person in a gray suit. The man in green stands, adjusts his pants, and walks away. The camera follows him as he moves along the street.

Discrete objects include pedestrians walking past (e.g., man in gray suit), a man in a green shirt standing and walking away from the camera, and seated individuals. Motion is driven by human locomotion.

Background elements (brick wall, storefronts) show no significant fluid motion (fire, water, wind) or uniform shifting; scene is urban with static architectural features.


A white goat with black spots stands on a porch near a wooden post. It lowers its head toward the ground, then shifts its head to the left, followed by turning its head to the right, occasionally glancing at a metal bowl beneath its legs. The goat remains stationary throughout, while the camera captures the scene from a fixed angle with minimal background foliage and outdoor furniture visible.

A white and black goat is moving its head and body slightly, indicating locomotion (e.g., eating or alertness).

The background (trees, structure) is stationary with no fluid or environmental motion observed. No fire, water, smoke, or wind is present.


A person in a red shirt and dark shorts dribbles a basketball, runs toward the hoop, jumps, and shoots; the ball passes through the net. The individual then walks rightward. The camera remains stationary at a low angle.

A person in a red shirt is moving across the gym floor via walking and running, which is due to locomotion.

No shifting background; no fluid or environmental motion (e.g., fire, water, wind). Background elements (walls, floor) are static.


Several men in blue and white striped shirts collaborate to replace a tire on the rear of a white race car with red and blue accents. They lift a black tire from the ground, position it onto the wheel well, and adjust it to secure it in place, moving around the car's rear. The camera captures the process from a fixed perspective, slightly angled to show their coordinated efforts.

Multiple people are actively manipulating a car tire, including pushing, pulling, and repositioning it using physical force. The car itself remains stationary while the tire and people exhibit clear locomotion and interaction.

The background elements (fence, ground, car structure) show no uniform shifting or fluid motion; there is no fire, water, or smoke present.


A person in a white shirt and dark pants exits a sliding glass door of a beige house, walks toward stacked wooden planks on the ground, bends to adjust them, and then moves away. The camera remains stationary, capturing the scene from a fixed, eye-level perspective with minimal background detail beyond the house and grassy area.

A person in a white shirt moves across the scene, performing actions like walking, bending, and interacting with the ground near the house entrance.

Background elements (house, ground, grass) are static with no uniform shifting; no fluid or wind-driven environmental motion observed.


A person in a black t-shirt holds a brown spherical object, raises it upward, tilts their head back as the object moves out of frame, then brings the object back into view. The background features a plain wall and a lamp to the left. The camera remains stationary with slight movement.

The man (solid object) and orange ball (solid object) are moving. The ball is thrown and caught by the man's hands, exhibiting projectile motion due to gravity and manual force application. The man's body also shows controlled movement consistent with juggling.

The background (plain wall and stationary lamps) remains static with no shifting or motion. There is no fluid/environmental motion (e.g., fire, water, smoke, wind) dominating the scene.


A person in a gray shirt and blue jeans folds dark blue jeans with a red inner lining. They lift the jeans, adjust their position with both hands, and place them onto a bed covered with a pile of mixed clothing. The camera maintains a static, slightly low-angle perspective throughout the sequence without movement.

A person (discrete solid object) is actively folding clothes (discrete fabric objects), with hands manipulating garments through explicit physical forces (lifting, folding, adjusting).

No shifting backgrounds; no fluid/environmental motion (fire, water, wind) observed. Walls and window remain static throughout.


A person in a teal shirt holds a large green bowl on a countertop, lifts the bowl upward, inverts it to display its empty interior, then lowers it back onto the countertop. The camera remains stationary with minimal movement, capturing the person in a kitchen setting with wooden cabinets visible in the background.

A person is actively manipulating a green bowl, pouring and stirring its contents. The bowl and the person’s hands are the primary solid objects in motion, driven by manual actions.

The background elements (walls, cabinets) remain static without uniform shifting. No fluid motion (fire, water, smoke) is visible; the scene is dominated by human actions with solid objects.


RAW CAPTION: Got it, let's tackle this video caption. First, the main subject is a person mixing salad. Let's break down the video frames.

In the first frame, it's a close-up of a table with plates and a bowl. Then, in the next frames, a person (wearing a white shirt and red pants, I think) is using two wooden spoons to mix a dark blue bowl filled with salad. The salad has veggies like carrots, maybe some greens. The table has white tablecloth with red placemats. There are empty plates and utensils.

Chronicling the motion: the person starts mixing, using both spoons to stir the salad. The action is continuous from frame 0 to 5.

Appearance: the person's hands, white shirt, red pants (from the visible part), the bowl is dark blue, salad has orange and green. Spatially, the bowl is on the table, plates are around, placemats red.

Camera perspective: the view is close-up, maybe top-down or slightly angled. The camera stays focused on the bowl and hands, so no significant movement, maybe slight shake. Background is minimal, just the table setup.

Now, follow the rules: focus on motion chronologically. Start with the person mixing. Describe the action step by step. Keep it concise.

Let's draft: A person wearing a white shirt and red pants uses two wooden spoons to mix a dark blue bowl of salad containing orange and green vegetables on a white tablecloth with red placemats. The person’s hands move the spoons in a circular motion, stirring the contents of the bowl. The table also holds empty white plates with silverware and red placemats. The camera remains close to the bowl, capturing the mixing action with a slight shake.

Check rules: motion first (mixing), appearance (shirt, pants, bowl, veggies), spatial (tablecloth, placemats, plates), camera (close-up, slight shake). Background minimal. Exclude text, names.

Wait, the first frame shows a hand stirring, then the next frames show the full action. So chronological: the person begins stirring with two spoons, continues mixing, the action progresses.

Make sure it's a paragraph. Let's condense.

"A person wearing a white shirt and red pants uses two wooden spoons to stir a dark blue bowl of salad containing orange and green vegetables on a white tablecloth with red placemats. The hands move the spoons in circular motions, mixing the contents throughout the sequence. The table also features empty white plates and silverware on red placemats. The camera maintains a close-up perspective of the bowl and hands, with slight camera shake visible during the action."

Wait, check if the background is minimal. The rules say background descriptions minimal unless essential. The table setup is essential for understanding the scene, so include.

Check the output format: must be in <caption_output> tags.

Let's check the example structure. The user provided an example in the rules, but the output should be the caption.

Another check: the video shows a person mixing salad, so main subject is the person's hands and the bowl.

Final draft: A person wearing a white shirt and red pants uses two wooden spoons to mix a dark blue bowl of salad with orange and green vegetables on a white tablecloth. The table has red placemats, empty white plates, and silverware. The hands move the spoons in circular motions, stirring the contents continuously. The camera remains close to the bowl, capturing the mixing action with slight shake.

Wait, "chronological paragraph" so start with the action starting.

"Beginning the sequence, a person in a white shirt and red pants uses two wooden spoons to mix a dark blue bowl of salad containing orange and green vegetables on a white tablecloth with red placemats. The hands continuously stir the contents, moving the spoons in circular motions. The table also holds empty white plates and silverware. The camera stays close to the bowl, showing slight shake during the mixing process."

But maybe more concise.

"A person in a white shirt and red pants stirs a dark blue bowl of salad with orange and green vegetables using two wooden spoons. The action occurs on a white tablecloth with red placemats, where empty white plates and silverware are placed. The hands move the spoons in circular motions throughout the sequence. The camera maintains a close-up view of the bowl with slight shake."

<caption_output>A person wearing a white shirt and red pants uses two wooden spoons to mix a dark blue bowl of salad containing orange and green vegetables on a white tablecloth with red placemats. The hands continuously stir the contents in circular motions, moving the spoons through the salad. Empty white plates with silverware and red placem

A person's hands are actively stirring food in a bowl using a spoon. The spoon and hands exhibit discrete, solid object motion due to explicit physical forces (stirring).

The background includes a table with plates, glasses, and a tablecloth. No uniform shifting or fluid/environmental motion (fire, water, smoke) is observed. Background elements appear stationary.


RAW CAPTION: Got it, let's tackle this captioning task. First, I need to focus on the motion and behavior of the main subjects. The video shows a person applying something to a fingernail. Let's break it down chronologically.

In the first frame, there's a person wearing a dark hoodie with green text, sitting at a table. Then, the hands come into focus. The person holds a small bottle, opens it, and uses a brush to apply liquid to a fingernail. The other hand is holding the nail steady. The action is applying nail product.

Now, describe the appearance: the hoodie is dark, green text, but maybe not essential. The hands—probably a person's hands, one with a nail being worked on, the other holding the brush. The bottle is small, dark, maybe amber. The brush is being dipped into the bottle, then applied to the nail.

Spatial relationships: the hand holding the nail is in front, the brush is moving towards the nail. The background is a table, but minimal.

Camera perspective: close-up, maybe slight movement as it zooms in on the hands and nail.

Check rules: exclude text recognition, so don't mention the pink text. Focus on motion: opening bottle, applying liquid. Number of subjects: one person (hands visible).

Putting it together: A person in a dark hoodie with green lettering sits at a table, then uses a small dark bottle and a brush to apply liquid to a fingernail held by the other hand. The camera captures close-up hand movements as the brush dips into the bottle and applies the product to the nail, with slight shifts focusing on the application process.

Wait, need to be concise. Let's check the output format: chronological paragraph. So start with the initial action, then steps.

First, the person opens a small dark bottle (maybe glass), then dips a brush into it, applies to fingernail. The hand holding the nail is steady. Camera close-up, following the action.

Make sure to mention motion: opening bottle, dipping brush, applying to nail.

Avoid background details unless essential. The table is maybe just the surface, but maybe minimal. So the main motion is the hands.

Let's draft:

A person in a dark hoodie with green text opens a small dark bottle, dips a brush into it, and applies liquid to a fingernail held steady by the other hand. The camera maintains a close-up view, shifting slightly to focus on the brush moving toward and applying the product to the nail.

Check rules: a) chronological order (open bottle, dip brush, apply), b) appearance: dark hoodie, green text (but maybe the text is part of the hoodie, so mention color, but maybe "dark hoodie with green lettering" is okay as appearance), c) spatial: one hand holds nail, other uses brush. d) camera: close-up, slight shift. e) background minimal, f) exclude text.

Wait, the hoodie's text is "HOLLISTER CALI" but we can't mention named characters, so "dark hoodie with green lettering" is fine. The bottle is small, dark. The brush is being used.

Another angle: The main subject is the hands. One hand holds a fingernail, the other holds a brush that dips into a small dark bottle. Then the brush applies liquid to the nail.

So: A person uses a brush to apply liquid from a small dark bottle to a fingernail held steady by the other hand. The person opens the bottle, dips the brush into it, and applies the product in a close-up shot, with the camera following the brush's movement toward and onto the nail.

Wait, need to be chronological. So first, the person opens the bottle (as seen in frame 2: hands opening bottle), then dips brush into bottle (frame 3: brush in bottle), then applies to nail (frame 4-5: applying).

So: A person opens a small dark bottle with their hands, dips a brush into it, then uses the brush to apply liquid to a fingernail held by the other hand. The camera focuses closely on the hands, shifting slightly to capture the brush moving toward and applying the product to the nail.

Check concise. Let's make sure it's a paragraph.

Final version: A person in a dark hoodie with green lettering opens a small dark bottle, dips a brush into it, and applies liquid to a fingernail held steady by the other hand. The camera maintains a close-up view, shifting slightly to follow the brush as it moves toward and applies the product to the nail.

<caption_output>A person in a dark hoodie with green lettering opens a small dark bottle, dips a brush into it, and applies liquid to a fingernail held steady by the other hand. The camera maintains a close-up view, shifting slightly

The primary discrete objects are the person's hands manipulating a nail file and a fingernail. The hands exhibit precise, controlled movements (e.g., filing, positioning) due to intentional physical interaction.

The background features a static table surface with minimal motion; no fire, water, smoke, or wind is present to dominate the scene.


Two individuals in dark pants approach from a doorway, manipulating a large beige bag, then proceed to walk away from the camera. The low-angle camera remains stationary, positioned close to the carpeted floor.

A person (legs visible) and a dog are moving. The person walks from left to right, and the dog is being handled (carried or petted) by the person.

The background (carpet and wall) is static and shows no uniform shifting. There are no fluid environmental motions (fire, water, smoke, wind).


A large herd of cows, varying in color (black, white, brown, and spotted), moves across a grassy field from right to left in a loose group, heads lowered as they graze while progressing. The background features tall crops. The camera pans left, tracking the herd's movement.

Discrete solid objects (cows) are moving: grazing, shifting positions, and interacting with the grass.

The background consists of static grass and distant horizon with no fluid/environmental motion (fire, water, wind) or uniform background shifting observed.


A person uses a light-colored hand plane on a piece of wood, moving it back and forth to generate thin shavings that accumulate to the right. After planing, the person lifts the plane, adjusts it, and sets the shavings aside on the textured surface. The camera maintains a top-down perspective with minimal movement.

A hand manipulates a wooden block on a plane, moving it back and forth with visible wood shavings accumulating. The hand and wooden block are distinct solid objects exhibiting motion due to manual interaction.

The background consists of a static fabric surface with wood shavings; no shifting background elements or fluid/environmental motion (fire, water, smoke, wind) observed.


Two hands shape a white, elongated dough piece on a red surface. They press and smooth the dough, then use a rolling pin to flatten it, moving the pin back and forth to extend its length. The camera remains top-down throughout the sequence.

A human hand is moving and applying force to roll a piece of dough, representing discrete object-to-object physics (hand-dough interaction).

The red surface background is static and shows no shifting or fluid motion. No fire, water, smoke, or wind is present, so ambient environmental motion is absent.


A man in a dark short-sleeve shirt, light-colored shorts, white socks, and white sneakers stands facing left near a doorway. He turns to face the camera, walks toward it, passes in front, and then moves away toward the doorway. The camera remains stationary throughout the sequence.

A single human subject (the man) is walking across the frame. The motion is due to his locomotion (walking).

The background (building, door, windows) is static and shows no fluid/environmental motion (fire, water, smoke, wind). The background does not shift uniformly, so camera motion is not present.


A woman in a blue top and white pants crouches beside a large white sheep lying on a dirt floor within a green metal enclosure. She uses electric clippers to shear the sheep’s wool, moving the tool methodically from the sheep’s side toward its back. Loose wool fibers accumulate around them as the sheep remains still. The camera remains static, providing a top-down view of the shearing process.

Discrete solid objects: a human (person) and a pig. The person is moving their hands and body to interact with the pig, while the pig exhibits slight movements (e.g., shifting weight, head motion) in response to the interaction.

The background consists of static green metal fencing and dirt ground with no shifting or movement. No fire, water, smoke, or wind effects are present to dominate the scene.


A boy in a brown hoodie leans over a wooden table with a tall green glass to the left, a clear bowl holding red sauce, and a yellow bag of chips. A second boy in an orange shirt is partially visible behind him. The first boy reaches into the yellow bag, retrieves a chip, and dips it into the bowl, while the second boy raises his right hand. The camera stays stationary at a low angle, centered on the table surface.

Two people are visible: one actively manipulating contents in a bowl (hand movements), and another observing. These are discrete solid objects with explicit physical motion due to intentional actions.

Background elements (green glass, yellow bag, kitchen items) show no uniform shifting or fluid motion; no fire, water, or smoke observed.


RAW CAPTION: Got it, let's break this down. First, the video starts with a person on a bed. The person is wearing a pink shirt with a smiley face and blue pants. They climb out of the bed, then jump down. Wait, no, the first frame shows them on the bed, then they step off. Wait, the sequence: at [0.0], they're on the bed, maybe sitting or leaning. Then [1.0], they move, [2.0] they're standing up, jumping? Wait, the timestamps: 0.0 to 2.5 seconds. Let's check the frames. The person is on the bed (0.0), then moves down (1.0), then jumps (2.0), then lands (3.0), then maybe falls back? Wait, no. Let's look at the actions. The person is initially on the bed, then gets up, jumps into the air, and then falls back onto the bed. Wait, the frames: 0.0: person is on bed, hand on bed. 1.0: they are in mid-air, jumping off the bed. 2.0: they're in the air, legs bent, arms up. 3.0: they land on the bed, but then 4.0: they fall back onto the bed, maybe? Wait, the fourth frame shows them lying on the bed. Let's map the actions:

- At start: Person (pink shirt, blue pants) is on the bed, leaning over.
- Then they jump off the bed (mid-air), arms up.
- Then they land back on the bed? Wait, no, in frame 4 they're lying on the bed. Wait, the movement: from the bed, they jump, then land on the bed. So the sequence is: person on bed, jumps up, then falls back onto the bed.

Now, the background: there's a room with a door, red carpet, window with red curtains, and a whiteboard with numbers (but per rule f, exclude text recognition, so just mention room elements minimally). But rule e says background descriptions minimal unless essential. So maybe just note it's an indoor room.

Main subject: one person, wearing pink shirt (with a smiley face, but rule f says exclude named characters or stylistic analysis, so just "pink shirt" maybe, but wait, rule b: describe appearance (color, size, etc.). So "a person wearing a pink shirt and light blue pants" – size not specified, so just color.

Spatial relationships: the person starts on the bed (which is against a wall with window behind), then jumps, lands back on the bed.

Camera perspective: the camera is fixed, maybe a slight angle from a doorway, so no movement.

Let's structure the caption:

- Chronological order: person is on the bed (initially), then jumps off, then lands back on the bed.

Check the frames:

0.0: person on bed, hand on bed edge.

1.0: person is in the air, jumping.

2.0: person is mid-air, arms up.

3.0: person is on the bed (landing? But in 3.0, they're standing, arms up? Wait, no, the frames:

[0.0] person is on bed, maybe sitting, then jumps up.

[1.0] person is in air, legs bent.

[2.0] person is still in air, arms raised.

[3.0] person is in air, maybe falling back.

[4.0] person is lying on bed.

Wait, the video description:

[0.0] person on bed, then [1.0] they step down (but frame 1.0 shows them moving), [2.0] they jump, arms up, [3.0] they land on bed? Wait, the description says:

"0.0: person on bed, arm up (maybe). 1.0: person stepping down from bed. 2.0: person jumping into air, arms up. 3.0: person in air, arms up. 4.0: person on bed."

Wait, let's parse the video:

- At 0.0: person is on the bed, leaning over (hand on bed edge).

- At 1.0: they move their hand, step down (beginning to jump).

- At 2.0: they jump up, arms raised.

- At 3.0: they're in mid-air (jumping), then at 4.0, they fall back onto the bed, lying down.

So the sequence is: person on bed, jumps up into the air, then falls back onto the bed.

Appearance: person in

A person climbs over a bed, walks around the room, and interacts with the bed (e.g., adjusting position, moving hands).

Background elements (walls, door, furniture) show no uniform shifting; no fire, water, smoke, or wind observed.


Two light-skinned fingers press and slide a small, iridescent object with shifting green, blue, and purple hues across a textured surface, moving it left to right while the metallic edge glints under their pressure. The camera maintains a close-up perspective with slight movement tracking the object’s motion.

The finger (a solid object) is moving along the edge of a CD/DVD (another solid object), causing the CD to shift slightly. This motion is due to physical interaction (pressure and movement of the finger).

No shifting background or fluid/environmental motion (fire, water, wind) observed. Background is static (dark surface) and the scene is focused on the finger and CD.


A person's hands dip a brush into a small container and apply the substance to a wooden block. The container sits next to a large red and white bottle with a blue brush protruding from its opening. The background features a gray couch and a table. The camera remains static, focusing closely on the hands and the bottle.

The person's hands are moving discretely while manipulating a small object near the Mod Podge bottle; the bottle and background furniture remain stationary.

Background elements (couch, wall) show no uniform shifting; no fire, water, or wind motion detected.


The seated individual manipulates a long cylindrical object while a group of people in colorful hats and jackets stands nearby, observing and shifting positions slightly. The camera pans gently to the right, maintaining a steady view of the scene with minimal background details visible.

A seated individual in the foreground and several standing people exhibit minor positional adjustments, indicating subtle locomotion or posture changes due to physical forces.

The background elements (pavement, black wall) remain static across frames with no uniform shifting or fluid motion. No fire, water, or smoke is present.


A hand holding a knife moves downward to slice a decorated cake. The cake, adorned with a red rose and black-and-white design, sits inside a white box with blue accents. The hand guides the knife across the cake’s surface, continuing the cut. The camera maintains a close-up perspective, capturing the action from a slightly angled top view with minimal movement.

A human hand (discrete solid object) is visible, moving (e.g., holding a pen, interacting with the card) due to explicit physical action.

Background elements (white box, blue card, cup) show no uniform shifting or fluid motion; no fire, water, smoke, or wind observed.


RAW CAPTION: Okay, let's tackle this. The user wants a concise caption following specific rules. First, I need to look at the video frames provided.

The first frame shows a close-up of red lips with a brush applying makeup. The text "DIY Makeup Hairstyles Nail Art TV" is there, but the rules say to exclude text recognition. So I should ignore that.

Next frame: the brush moves away, maybe applying product. Then the third frame shows a pin on the lips, maybe for a design? Wait, the user mentioned "main subjects: people/animals/objects." The main subject here is the lips, which are red. The brush and the pin are tools used on the lips.

Chronic order: brush applying makeup, then the pin is used. The background has a colorful scene with yellow and purple structures, but per rule e, keep background minimal unless essential. Since the background isn't part of the action, maybe just mention "colorful backdrop" briefly.

Spatial relationships: the brush is in front of the lips, the pin is on the lips. The camera is close-up, likely static but maybe slight movement. Wait, the frames show the brush moving, then the pin. So the motion is the brush applying, then the pin being inserted.

Appearance: red lips, brush with dark handle, pin. Number: one lip, one brush, one pin.

Check rules: focus on motion. Start with brush applying makeup, then pin being used on the lips. Mention the red color of the lips. Background is colorful but minimal. Conclude with camera perspective: close-up, possibly static.

Wait, rule d says to mention camera perspective and movement. The examples given are top-down, pan left, etc. The video seems to have a close-up view, maybe slightly moving as it shows the brush and pin.

Putting it all together: A close-up view shows a hand using a makeup brush to apply red product to full lips, then a thin pin is used to create a design on the upper lip. The lips are glossy red, the brush has a dark handle, and the pin is metallic. The background features a colorful setting. The camera remains close and steady throughout.

Wait, the user said "people/animals/objects" – the lips are part of a person, so the main subject is the lips. But the hand holding the brush is part of the person. However, the captions should focus on the motion. The main action is the brush applying, then the pin.

Check rule a: chronological order. First, brush applying makeup (moving in a certain way), then the pin is used.

Make sure to mention the motion: the brush is applied to the lips, then the pin is inserted. The lips are red, the brush is moving, the pin is metallic.

Background: minimal description, maybe "colorful backdrop" but not detailed.

Final caption: A close-up shot shows a hand using a dark-handled brush to apply glossy red makeup to full lips, then a metallic pin is inserted into the upper lip to create a design. The lips remain the central focus against a colorful background. The camera maintains a steady close-up perspective throughout.

Wait, the rules say to exclude text recognition. The text is on the screen but we don't mention it. Also, check if the pin is part of the action. Yes. The pin is being used to draw a line or create a design on the lips. So the motion is the brush applying, then the pin creating a design.

I need to keep it concise. Let me structure it:

A close-up view shows a brush applying glossy red makeup to full lips, then a thin pin is used to draw a white line on the upper lip. The lips are vivid red with a smooth texture. The camera stays static, focusing tightly on the lips against a colorful backdrop.

Wait, the video shows the brush moving, then the pin. The first frame is brush applying, then the next frames show the pin. So in chronological order, the brush applies, then the pin is used.

Yes. The caption should describe that sequence. Also, note the appearance: red lips, brush, pin. Spatial: pin on the lips.

Another check: exclude named characters, so no mention of a person's name, just "lips" as the main subject.

So final answer: A close-up sequence depicts a brush applying glossy red makeup to full lips, followed by a metallic pin drawing a white line on the upper lip. The lips remain the central focus with a vivid red color against a colorful background. The camera maintains a steady close-up perspective throughout.

<caption_output>A close-up sequence depicts a brush applying glossy red makeup to full lips, followed by a metallic pin drawing a white line on the upper lip. The lips remain the central focus with a vivid red color against a colorful background. The camera

The brush is a solid object moving across the lips to apply nail art, indicating motion due to explicit human action.

No shifting background or fluid/environmental motion (fire, water, wind) detected. Background is blurred but static elements (colors) are present without uniform movement.


RAW CAPTION: Got it, let's break down the video. First scene: two kids, one in red shirt, one in striped, handling red and blue bowls with colorful objects. Then they move to a wall with a faucet, filling the red bowl. The woman in red helps, smiles. The camera shifts from the initial scene to them at the faucet. Need to describe chronologically.

Start with the first frame: two children, one in red shirt (wearing shorts, holding red bowl) and another in striped shirt (wearing shorts, holding blue bowl with toys). Then they go to the faucet: the child in striped shirt operates the faucet, woman in red helps fill the red bowl. They interact, woman smiles. Camera perspective: starts with a close-up of the kids with bowls, then shifts to a top-down or overhead view? Wait, the video description says first frame is top-down maybe? Wait, the first frame: two kids, one in red, one in striped, handling red and blue bowls. Then next scenes: they are near a wall with a faucet, filling the red bowl. The camera movement: maybe a pan to the right or shifting focus.

Need to check the rules. Chronological paragraph. Main subjects: two kids (one in red, one in striped), then a woman in red (wait, the first frame has a woman in red? Wait, the first frame: "two children, one in red shirt, one in striped shirt. Then the next frames: a woman in red (maybe same as the kid?) Wait, the video shows:

Frame 0: two kids, one in red (shirt), one in striped (shirt), with red and blue bowls. Then frame 1: they are at a wall with a faucet, the child in striped shirt is turning on the faucet, the woman in red (maybe the same person? Wait, the first frame is the children, then in the next frames, the woman (red shirt) and child (striped) are filling the bowl. Oh, maybe the woman is an adult, the child is a kid.

So sequence:

1. Two children (one in red shirt, one in striped shirt) are seen with red and blue bowls containing colorful toys or items on a gravel surface.

2. They move to a wall with a water faucet; the child in striped shirt turns on the faucet while the adult in red shirt assists in filling the red bowl.

3. The adult smiles as the child continues filling the bowl, with both interacting closely near the faucet.

Camera perspective: starts with a top-down view of the children with bowls, then shifts to a side view focusing on the faucet activity.

Wait, the first frame description: "two children, one in red shirt, one in striped shirt, with red and blue bowls on a gravel surface". Then frame 1: they are at the wall with a faucet. So the first part is them with the bowls, then moving to the faucet.

Need to keep it concise, chronological.

Let's structure:

Initially, two children (a girl in a red shirt and a boy in a striped shirt) stand on a gravel surface, each holding a red and blue bowl filled with colorful objects. They then move to a wall with a water faucet, where the boy turns on the faucet while the girl assists, filling the red bowl. The girl smiles as the boy continues pouring water from the faucet into the bowl. The camera shifts from a top-down perspective of the children with the bowls to a closer, side-view angle focusing on their interaction at the faucet.

Check rules:

a) Motion and behavior: kids move from gravel to faucet, turn on faucet, fill bowl.

b) Appearance: girl in red, boy in striped. Bowls red and blue.

c) Spatial: initially on gravel, then at wall with faucet.

d) Camera: starts top-down, then shifts to side view.

e) Background minimal: gravel surface, wall.

f) No text, no named characters.

Wait, the first frame: "two children, one in red shirt, one in striped shirt, with red and blue bowls" — yes. Then frame 1: they are at the wall with faucet, boy turning faucet, girl assisting.

Need to make sure chronological order.

First, the kids are at the gravel with the bowls. Then they go to the faucet to fill the bowl.

Caption:

A girl in a red shirt and a boy in a striped shirt stand on a gravel surface, each holding a red and blue bowl filled with colorful objects. They then approach a wall with a water faucet; the boy turns the faucet on while the girl assists in filling the red bowl. The girl smiles as the boy continues pouring water into the bowl, with the camera shifting from a top-down view to a closer, side-facing angle focusing on their interaction.

Check if concise. Maybe shorten.

Alternatively:

A

Two children (a girl in red and a boy in blue) are moving their hands and bodies to fill a red bowl with water. The motion is discrete and solid (people moving).

The background (wall, structure) is static with minimal movement. The water flow from the tap is visible but not dominant; it is a secondary effect of the children's actions and thus not the primary motion.


A person wearing a dark shirt and glasses repeatedly tosses a white plate upward in a room with orange walls. The plate travels from the person’s hands into the air, is caught, and rethrown multiple times. The ceiling light and wall decorations are visible in the background. The camera remains stationary, capturing the motion from a low angle.

A person manipulates a plate with visible arm movements; the plate is tossed and caught, exhibiting discrete motion due to the person's physical actions.

Static orange walls, framed pictures, and ceiling fixtures show no uniform shifting. No fire, water, smoke, or wind observed; ambient elements are negligible.


RAW CAPTION: Got it, let's tackle this. First, the video shows a squash court with four players. Need to describe their actions in order.

At the start (0s), four men are on the court. One in red shirt and black shorts (maybe) is on the left, another in dark shirt, then two more. The first player (red) swings his racket, hitting the ball towards the front. Then the ball goes, and the players move. Let's check the timestamps.

0.0: All four positioned. Red shirt player (left) swings, hits ball. Then in 1s, he's moving, maybe the ball is hit. Then 2s: red player dives to the left? Wait, the video shows movement. Let's see:

- Frame 0: Four players, red shirt on left, then dark shirt, then green shirt, then black shirt. Red swings racket, hits ball. Then in frame 1, red is still, maybe the ball is in motion. Then frame 2, red moves towards left (maybe to retrieve?), then in frame 3, red is near the wall, then frame 4, he's back, and others move.

Wait, the key is to list the actions in chronological order. Let's parse each frame.

First frame: 0.0s: Four men. Red shirt (left), dark shirt (middle), green shirt (right), black shirt (far right). Red swings racket, hits the ball towards the front. Then in 1s, the ball is hit, players react. Red moves left, the dark shirt player is now near the middle, green and black shirts move as well.

Then frame 2: Red is moving left (towards the back wall), dark shirt is standing, green and black are moving towards the right. Frame 3: Red is near the back wall (left side), dark shirt is in the middle, green is moving, black is on the right. Frame 4: Red is moving towards the center, dark shirt is moving towards the right, green and black are near the right.

Wait, maybe better to track the sequence: The player in red shirt hits the ball, then the other players react. The red player moves towards the left wall after hitting, then others position themselves. Let's structure the description.

Main subjects: four male players. Appearance: red shirt/black shorts, dark shirt/black shorts, green shirt/black shorts, black shirt/gray shorts (assuming).

Chronological:

- Initially, four men stand on the squash court. The man in red shirt hits the ball with his racket towards the front.

- Then, the red-shirted man moves left, bending to retrieve the ball.

- The man in dark shirt steps forward, while the green-shirted and black-shirted men shift positions.

- Subsequently, the red-shirted man runs towards the center, the dark-shirted man moves right, and the other two reposition.

But need to be concise. Also, mention spatial relationships. Let's check the video frames:

Frame 0: Four players in a line. Left: red shirt, then dark shirt, then green, then black. Red swings, hits ball.

Frame 1: Red is still, dark shirt is in center, green is moving right, black is moving left.

Frame 2: Red is moving left (towards left wall), dark shirt is standing, green is moving towards right, black is moving.

Frame 3: Red is near left wall, dark shirt is center, green is right, black is near right.

Frame 4: Red is running towards center, dark shirt is moving towards right, green and black are near right.

So the order of actions:

1. Red-shirted player hits the ball with racket (swings left to right, maybe).

2. Then, red player moves towards left wall (bends down), others react.

3. Then, red player runs towards center, dark-shirted moves right, others adjust.

Now, concise description:

Four men on a squash court: red shirt/black shorts, dark shirt/black shorts, green shirt/black shorts, black shirt/gray shorts. The red-shirted player swings his racket to hit the ball toward the front, then moves left toward the wall, bending to retrieve it. The dark-shirted player steps forward, while the green- and black-shirted men shift positions. Subsequently, the red-shirted player runs toward the center, the dark-shirted man moves right, and the others reposition. The camera remains stationary, capturing the players' movements from a fixed angle.

Wait, need to check if "bending to retrieve" is accurate. In frame 2, the red player is near the wall, maybe hitting the ball towards the left? Wait, the first action is the red shirt player hitting the ball. Then

Four solid human objects (players with squash rackets) and a squash ball exhibit discrete motion: players move through court, swing rackets, and collide with ball; ball trajectory shows clear impact-based motion.

The background (walls, floor) shows no shifting, fluid motion, or environmental effects. No fire, water, smoke, or wind observed. Background remains uniformly static.


A person in a light gray jacket and dark pants crouches beside a horse's lower leg, adjusting a red bandage with white edges wrapped around the leg; the horse wears black boots, and the scene shifts to a close-up of the bandaged leg as the person finishes securing it. The camera starts in a medium shot and zooms in to focus on the bandaged leg.

Two people: a standing person (red sleeve, white pants) and a kneeling person (gray jacket, blue jeans) interacting. The kneeling person's hands move to adjust the standing person's shoes/socks.

The background (sandy ground and distant vehicle) is static with no significant shifts or environmental motion (e.g., fire, water, wind).


A person in a white shirt crouches beside a black cow, holding a rope near the cow's hind leg. The cow steps forward, prompting the person to adjust the rope, while the cow's head moves toward the ground. The camera remains stationary, capturing the interaction from a ground-level angle on a dirt surface scattered with leaves and debris.

Discrete objects: person (crouching, moving hands with cloth) and cow (lowering head to interact with cloth). Motion consists of controlled hand movements and subtle head lowering by cow, indicating physical interaction (feeding).

Background shows stable ground with debris and static elements (plastic sheet, distant figure). No shifting or uniform motion detected in background. No fire, water, smoke, or wind present.


A pair of hands manipulates a colorful 3x3 Rubik's Cube, rotating its layers to align the squares. The cube, featuring vibrant red, blue, green, yellow, orange, and white faces, is held centrally while the smartphone rests on a granite countertop to the right. The camera maintains a static top-down perspective, capturing the cube's shifting orientation and the hands' precise movements.

A Rubik's cube is being manipulated by hands, with rotations and turns of the cube faces. The cube is a solid object and the motion is due to physical manipulation by the hands.

The background (granite countertop and smartphone) is static and shows no shifting or environmental motion. No fire, water, smoke, or wind are present.


A man wearing a black shirt and red shorts lifts a barbell, beginning in a squat position, rising to a standing stance while lifting the barbell, then stepping back into a lunge, and finally returning to a standing position. The scene takes place in a gym with red weightlifting equipment; the camera remains static throughout.

A person (discrete solid object) is performing weightlifting motion (squat/lunge variations), moving the barbell through explicit physical forces (muscle contraction, weight resistance).

Background elements (gym equipment, walls, floor) remain stationary with no fluid/environmental motion (fire, water, smoke, wind); background shows no uniform shifting.


A shirtless man in black shorts sits on a wooden platform facing a calm river bordered by dry grass and greenery. He dips his right foot into the water, creating a splash, then extends his right arm forward toward the water. The camera remains stationary, positioned low near the water's edge, capturing the action from the platform's perspective.

A shirtless man moves his arm to splash water, causing discrete water droplets and fish to react; the man's arm motion is a solid object interacting with fluid, and fish movement is a result of the splash.

The riverbank and vegetation show no uniform shifting, indicating no camera-induced motion. The river's surface has gentle flow, but it is not the dominant motion; this subtle environmental movement is secondary to the primary action.


In an indoor netted area with artificial grass, a person in a colorful rainbow shirt, black shorts, and knee pads crouches near a green mat, then stands and throws a yellow ball. The scene shifts to another individual in a black shirt with white "S9" on the back, facing the first person. The first person, now on a black mat with pink lines, crouches low holding a ball, then throws it forward. The camera captures these actions from ground-level angles, transitioning between the two shots without visible movement.

The main subject is a person in a colorful shirt performing discrete actions: kneeling, standing, lifting, and swinging an object (likely a bat or similar). Another individual is present and moving within the scene.

The background elements (walls, curtains, netting, and indoor equipment) remain static throughout the video. There is no fluid or environmental motion (fire, water, smoke, wind) present.


A person wearing a dark t-shirt and blue jeans sits on the floor, holding a snack. They bring the snack to their mouth to eat, then move their hands and look downward. Two red cups sit on the floor in front of them, with a bed and laundry basket visible in the background. The camera remains stationary, positioned at a low angle.

A person (solid object) exhibits hand movements and slight body shifts due to eating and adjusting posture.

Static background elements (wall, laundry basket) show no uniform shifting; no fire, water, smoke, or wind motion observed.


A boy in a blue shirt sits at a piano, playing continuously under a staircase with a glass railing. The camera remains stationary, positioned at an elevated angle to capture the scene.

A person is seated on the bed, with subtle hand movements and slight body shifts; these are solid, distinct motions from the individual.

Background elements (bed, curtains, wall) are static; no fluid motion (fire, water, smoke, wind) or environmental effects observed.


A pair of dark-skinned hands holds a white egg with a visible yellow yolk, then cracks it open, allowing the egg contents to spill out. The egg is positioned above a surface, with a bright pink container visible to the right. The background includes a blurred orange package and a white appliance. The camera remains close-up and steady throughout the sequence, focusing on the hands and egg.

Hands (cracking egg), egg (splitting and moving into bottle), and bottle (receiving egg) exhibit solid-object motion from explicit physical forces (cracking action).

Background elements (pink container, white surface) are static; no fluid/environmental motion (fire, water, smoke, wind) detected.


A person in a white shirt with yellow and grey stripes lies on a bed, then sits up and leans forward to interact with another person partially covered by a blue blanket. The camera captures close-up motion with slight handheld movement.

A person in a white/yellow striped shirt moves from an upright position to lying down on a bed, adjusting posture and head position. Solid object motion is evident due to voluntary locomotion.

Pink wall and computer monitor remain static throughout; no fluid motion (fire, water, smoke) or wind-induced environmental phenomena observed. Background elements do not shift uniformly across frames.


RAW CAPTION: Okay, let's see. I need to generate a concise caption for this video. First, the user provided a video description with timestamps from 0 to 5 seconds. The main subjects here are a person and a dog. The person is riding the dog, maybe? Wait, looking at the frames: the first frame shows a person in a white top and orange pants on a dog. The dog is moving, and the person is holding onto something. Wait, but the dog seems to be on a mechanical ride, like a carousel? Because in the background, there are lights and maybe a nighttime setting.

Wait, the user says to focus on motion and behavior in chronological order. Let me check the frames again. The video starts with the person on the dog, which is moving. The person is holding onto a handle or something. The dog is brown, maybe a large breed. The person is wearing white top and orange pants. Then, the dog moves, the person adjusts their position. The background has city lights, so it's nighttime. The camera is probably handheld, since there's a slight shake mentioned in the rules.

The rules say to mention spatial relationships, appearance, number. So main subjects: one person, one dog. Appearance: person in white top, orange pants; dog is brown. Motion: the person is riding the dog, which is moving forward. The dog is on a moving platform, maybe a mechanical ride. The person is holding onto a bar, maybe. Then, the camera moves a bit, following the motion.

Wait, the video description shows the person on the dog, which is moving. The dog is walking, and the person is holding on. But maybe the dog is part of a mechanical ride, like a carousel horse? Because in some amusement parks, there are mechanical rides where you ride on horses that move. But in this case, the dog is the horse. Wait, the video says "a dog" but maybe it's a mechanical horse? Wait, the first frame says "a dog" but the person is riding it. Hmm, maybe it's a dog that's part of a mechanical ride. But the video shows the person holding a handle, which might be part of the ride.

Wait, the user's description says: "a person wearing a white top and orange pants riding a brown dog on a moving platform. The dog moves forward, and the person adjusts their position, holding onto a bar. The background has blurred city lights, indicating nighttime. The camera follows the movement with slight shake."

Wait, the original video frames might have a dog that's actually a mechanical horse. But the description says "dog," so maybe the animal is a dog, which is unusual but possible. Alternatively, maybe it's a mechanical horse. But according to the problem statement, the user says "a dog" in the description. Let me check the user's problem statement again.

The video starts with [0.0] seconds: "a person wearing a white top and orange pants riding a brown dog on a moving platform. The dog moves forward, and the person adjusts their position, holding onto a bar. The background has blurred city lights, indicating nighttime. The camera follows the movement with slight shake."

Wait, the user provided the video description in the problem, but the actual video might show a mechanical ride. But according to the problem, we have to focus on the subjects as described. Wait, no, the task is to generate the caption based on the provided video frames. The user has given the frames, but the actual video's content is described in the frames. Let me check the frames again.

Looking at the frames: [0.0] shows a person in white top and orange pants riding a brown dog. The dog is moving, and the person is holding a handle. The background has lights, indicating a nighttime city scene. The dog is on a moving platform, so it's a mechanical ride. The person is adjusting their position as the ride moves. The camera is following the motion, possibly handheld, causing a slight shake.

So the caption needs to be chronological. Let's break it down:

- At the start, the person (white top, orange pants) is on the brown dog, which is moving on a platform.

- Then, the dog continues moving forward, and the person adjusts their position.

- The background has city lights.

- Camera perspective is following the motion with slight shake.

Mention spatial relationships: The person is seated on the dog, which is moving forward. The background is blurred city lights.

Appearance: one person (white top, orange pants), one brown dog.

Number: one person, one dog.

Chronological order: starts with person on dog moving, then adjusting position, background context.

Camera movement: follows the ride with slight shake.

Background minimal, just city lights.

So putting it all together concisely:

"A person in a

A person riding a horse moves across the frame from left to right. The horse's gait and rider's posture indicate locomotion due to explicit physical forces (muscle movement, gravity).

No shifting backgrounds or fluid/environmental motion (fire, water, wind) observed. Static ground markings (yellow lines) and distant lights remain stable without uniform displacement.


RAW CAPTION: Got it, let's break this down. The video starts with two kids. One is crouching by a bucket, wearing a white and blue shirt with pink shorts. The other is standing behind, in a blue shirt and dark shorts, holding blue objects. Then the crouching kid stands up, throws something, and the standing kid runs away. Wait, no, let's check the timestamps.

First frame: kid in blue shirt (top, holding blue items) and kid in white/blue shirt + pink shorts crouching by bucket. Then in next frames, the crouching kid stands, throws, maybe a ball? The standing kid moves back. Let's track actions.

Chronological order:

1. Initial scene: child in blue shirt (standing, arms up, holding blue items) and child in white/blue shirt/pink shorts (crouched by bucket).
2. Crouched child stands up, throws object (hand motion).
3. Standing child (blue shirt) steps back or runs away.

Appearance: two children. One in blue shirt with dark shorts, one in white/blue shirt, pink shorts. Spatial: initially, the blue-shirted child is behind the crouched child. When crouched child moves, the blue-shirted child retreats.

Camera: seems top-down view, maybe static, since no mention of movement. Background is grass and pavement, but minimal per rules.

Now, concise paragraph. Focus on motion and behavior.

First, describe the two children. Then their actions in order. Mention appearance briefly. Spatial relationships as needed.

Start: Two children are outside on a paved surface next to grass. One child in a blue shirt and dark shorts stands with arms raised, holding blue objects; the other child in a white and blue shirt with pink shorts crouches by a bucket. The crouched child then stands, throws an object, and turns toward the camera, while the standing child steps back and runs away.

Wait, check the frames: in frame 0, blue-shirt kid is standing, arms up (holding blue). Crouched kid is by bucket. Frame 1: crouched kid starts to stand. Frame 2: crouched kid is standing, blue-shirt kid is still there. Frame 3: crouched kid is moving, blue-shirt kid is behind. Frame 4: crouched kid is walking toward camera, blue-shirt kid is behind, running.

Wait the video: [0.0] blue-shirt kid standing, arms up; crouched. [1.0] crouched kid stands, blue-shirt kid still there. [2.0] crouched kid stands, blue-shirt kid starts to move. [3.0] crouched kid runs toward camera, blue-shirt kid is behind. [4.0] crouched kid is in front, running.

So chronological: Initially, a child in a blue shirt and dark shorts stands behind a child crouched by a bucket; the crouched child (white/blue shirt, pink shorts) stands, throws an object, and runs toward the camera, while the blue-shirted child steps back and retreats.

Check rules: mention appearance (color, size, orientation). Number is two. Spatial: blue-shirt kid is behind, then steps back. Camera: top-down (since it's looking down from above). Background minimal.

Now, structure:

Two children interact on a paved area. A child in a blue shirt and dark shorts stands behind a child wearing a white and blue shirt with pink shorts, who is crouched by a bucket. The crouched child stands, throws an object, and runs toward the camera, while the standing child steps back and retreats. The camera maintains a top-down perspective.

Wait, check if "crouched child stands" is part of motion. Yes. Also, need to mention the action of throwing. So:

A child in a blue shirt and dark shorts stands behind another child crouched by a bucket. The crouched child, wearing a white and blue shirt with pink shorts, stands, throws an object, and runs toward the camera, while the standing child steps back and retreats. The camera captures the scene from a top-down perspective.

Check conciseness. Let's see:

Two children are outside on a paved surface. A child in a blue shirt and dark shorts stands behind a child crouched by a bucket. The crouched child (white/blue shirt, pink shorts) stands, throws, and runs toward the camera; the standing child steps back. Camera is top-down.

Yes, that's concise. Now, make sure to follow the output format exactly.
</think>

<caption_output>Two children interact on a paved surface next to grass. A child in a blue shirt and dark shorts stands behind a child crouched by a bucket
