RAW CAPTION: Got it, let's tackle this captioning task. First, I need to focus on the main subjects: the baby and the adult's hand. The video starts with the baby lying down, shirtless, with a necklace. The baby is dark-skinned, small, lying on a light-colored cloth. Then there's an adult hand on the baby's stomach.

Chronologically: In the first frame, the adult hand is touching the baby's stomach. Then, the hand moves slightly, and the baby moves their hands. Wait, the baby's hands are moving, maybe trying to touch the hand? Let's check the sequence. The baby is on the left, the hand is on the right. The hand is moving, and the baby's hands are moving towards it.

Appearance: Baby is dark-skinned, no clothes, necklace. Adult hand is larger, maybe older person's hand. The baby is lying down, so orientation is supine. Spatial relationship: Hand is to the right of the baby, touching the belly. Then the baby moves their arms, reaching towards the hand.

Background: Minimal, just a cloth. The number 2 in a blue box is text, but we need to exclude text recognition per rule f. So ignore that.

Camera perspective: Top-down? The video seems to be looking down at the baby, so top-down. No movement mentioned, so probably static.

Let's structure it. Start with the baby's position, then the hand's action, then the baby's response.

Main subjects: Baby (dark-skinned, shirtless, lying on light cloth) and adult hand (moving over baby's stomach). Then the baby moves hands, maybe touching the hand.

Chronological order:

- The baby lies on its back, shirtless, with a dark necklace, while an adult's hand presses gently on the baby's belly.
- The hand moves slightly, and the baby's hands lift and move toward the adult's hand, appearing to interact.

Check rules: Focus on motion. The hand's motion, baby's hand movement. Appearance: baby's color, size (small), shirtless. Spatial: hand to the right of baby. Camera: top-down, static.

Now, condense into a concise paragraph.

"Baby, dark-skinned and shirtless, lies on its back on a light cloth while an adult's hand presses gently on the baby's stomach; the hand moves slightly, and the baby lifts its hands toward the hand, interacting with it, from a top-down camera perspective with no significant movement."

Wait, need to check if the background is minimal. The cloth is part of the background but maybe essential? The problem says minimal unless essential for understanding motion. The cloth is where the baby is lying, so maybe include "on a light-colored cloth" to set the scene. But the rules say minimal, so maybe just "on a cloth" but the user example might not need. Wait, in the initial description, the baby is on a cloth, so maybe that's part of the setting.

Also, the baby's hands are moving—specifically, in frame 3-4, the baby's hand reaches out. Let's check the frames: frame 0, hand on belly; frame 1, hand moves up a bit; frame 2, baby's hand moves up; frame 3, baby's hand is near the necklace; frame 4, baby's hand is touching the necklace area. Wait, the hand is moving, and baby's hands are moving toward it.

So the sequence: Adult's hand touches baby's belly, then moves, and baby's hands move to touch the hand or reach for it.

Final caption should be chronological, concise.

"An adult's hand gently presses and moves over a dark-skinned, shirtless baby's belly while the baby lies on its back on a cloth; the baby lifts its hands to touch the hand, from a top-down camera angle with minimal movement."

Check if "shirtless" is necessary—yes, as part of appearance. Size: baby is small, but "dark-skinned" and "shirtless" are appearance details.

Let's see: the main subjects are the baby and the hand. Motion: hand moves on belly, baby's hands move toward the hand.

Another version: "A dark-skinned baby, shirtless and lying on its back on a light cloth, has an adult's hand pressing on its stomach; the hand moves slightly, and the baby lifts its hands to interact with the hand, captured from a top-down perspective."

That's concise. Ensure it's chronological: hand presses, moves, baby moves hands.

Yes, that works.

<caption_output>A dark-skinned, shirtless baby lies on its back on a light cloth as an adult's hand gently presses on its stomach; the hand moves slightly, and

Baby's hands and adult's hands exhibit distinct motion: baby reaches toward belly button, adult's hands adjust position and gently hold the baby.

No shifting background elements observed (blanket remains stable); no fire, water, smoke, or wind motion detected.


A person wearing dark pants with white stripes and black shoes holds a yellow and black power drill, drilling into a concrete surface. The camera initially focuses on the person’s legs and drill, then tilts downward to show the drill bit penetrating the concrete. The background consists of a concrete floor.

The video opens with multiple dog sled teams moving across a snow-covered plain under mountainous terrain. A person in a red jacket sleds ahead, pulled by a line of huskies with white and black fur. The camera follows the team, capturing their motion across the snow. It then transitions to a close-up of a person in a blue jacket crouching to photograph two huskies with red and blue harnesses. The camera shifts from a wide, tracking perspective to a static close-up.

Discrete objects include people (in red and blue jackets) and sled dogs (Huskies) moving across the snow. In the first part, the group is moving toward the camera; in the second part, the person interacts with the dogs (crouching and petting), causing slight movements of the dogs.

The background (mountains, snow-covered trees) is static throughout the video. No significant fluid motion (fire, water, smoke, or wind) is visible that would dominate the scene. The snow appears still, and the only motion is from the subjects.


RAW CAPTION: Got it, let's break down the video. First, there's a red SUV on a basketball court. Three people are near the back of the SUV, pulling something—maybe a cart or a box? Wait, the first frame shows them standing. Then, in the next frames, they're moving. Let's check the sequence.

Frame 0: Red SUV is stationary, three people (maybe two adults, one child?) near the back, one person in blue on the left. Background has a basketball hoop and a fence.

Frame 1: The SUV starts moving slightly. The three people near the back are still there, but the person in blue is standing.

Frame 2: The SUV moves forward, the three people are now pulling a cart? Wait, the description says "pulling" but in the frames, they're walking. Let's see the motion: the SUV is moving to the right (from the viewer's perspective). The people near the back are walking alongside it, maybe pushing or pulling something.

Wait, the task is to describe motion chronologically. So start with the initial state, then what happens.

Main subjects: red SUV, group of people (let's count: in frame 0, there are three people near the SUV—two adults and a child? The video description says "three people" but maybe more? Wait, the first frame: "a red SUV... three people" near the back, one person in blue on the left.

Wait, the video has 5 frames. Let's check:

Frame 0: Red SUV (center), three people to the right of the SUV (near the back), one person in blue to the left. Background: basketball court, buildings, trees.

Frame 1: SUV moves a bit to the right, the three people are still near the back. The person in blue is still on the left.

Frame 2: SUV moves more right, the three people are now walking towards the right, pulling something? Wait, the SUV is moving, so the people are either pushing or pulling. Wait, the SUV is in motion, so the people might be moving with it.

Wait, maybe the SUV is moving forward, and the group of people (three) are walking alongside it, from the back towards the front. Let's track their positions.

In frame 0, the SUV is positioned with the back facing left (since it's moving right). The group is at the back of the SUV. Then, in frame 1, the SUV moves right, the group is still at the back. Frame 2: SUV moves more right, group starts moving forward? Wait, maybe the group is pushing the SUV? But the SUV is moving, so they might be pulling a trailer or something. Wait, the problem says "pulling" in the initial description. Wait, the video shows the SUV moving, and the people near the back are pulling something.

Wait, maybe the people are moving the SUV. But the SUV is a Jeep, so maybe it's being towed. The three people are standing near the back, pulling a tow rope. But the SUV is moving. So as the video progresses, the SUV moves forward on the court, with the three people walking alongside it, pulling (or guiding) it.

Let's structure the caption:

First, describe the initial scene: red SUV (medium-sized, red) is stationary on a basketball court, with three people (adults, possibly one child) near its rear. A person in blue stands to the left. Then, the SUV begins moving forward (toward the right), and the three people walk in the same direction, pulling a cart or object attached to the SUV. The SUV continues moving, the group stays close, and the camera remains stationary, capturing the scene from a fixed position.

Wait, but need to be concise. Check rules: focus on motion and behavior in chronological order. Number of people: three near the SUV, one in blue. Appearance: red SUV (size: medium SUV), people: three (colors not specified, but maybe blue shirt is notable). Spatial: the three people are at the rear of the SUV, one person in blue is to the left. Motion: SUV moves rightward, the three people walk along with it, moving from the rear towards the front (maybe pulling a trailer). Background: basketball court, hoop, fence (minimal).

Let's draft:

A red SUV moves slowly across a basketball court, with three people walking alongside its rear and pulling a cart or object. A person in blue stands to the left, observing. The SUV progresses rightward as the group maintains pace, with the camera remaining static overhead.

Wait, check the frames:

Frame 0: SUV is stationary? Or moving? The first frame shows the SUV, then in subsequent frames, it's moving. Let's see the description:

At [0.

The three individuals (two near the SUV and one standing apart) exhibit locomotion: the two on the right walk away from the SUV towards the right side of the frame, while the person on the left remains relatively stationary.

The background (buildings, trees, and ground) remains stationary with no significant shifts or environmental fluid motion (fire, water, wind).


A person in a blue shirt climbs a tree, gripping and shifting between branches while moving upward through the foliage. The camera maintains a low-angle perspective, following the climber's ascent with minimal movement.

A person climbing a tree, moving upward using the branches. Motion is due to their own physical effort.

Background shows tree leaves swaying due to wind (ambient motion), but no fire, water, or smoke. The tree and sky are mostly static with minor wind effects.


A large group of people in yellow and black uniforms march down a street, carrying large yellow and black flags. They move in synchronized steps, forming a line as they proceed. Spectators line the sidewalks, watching the procession. The camera follows the parade, panning slightly to capture the marching participants and the crowd along the street.

The marching band members (wearing yellow uniforms) are moving via coordinated locomotion (walking) and flag-waving. Their motion is discrete and solid, with clear bounding box tracking due to distinct physical movement.

The background (buildings, trees, street) shows no significant shifting or fluid motion; static elements remain stable throughout the frame. No fire, water, smoke, or wind-driven environmental effects dominate.


RAW CAPTION: Got it, let's tackle this. First, I need to go through each frame in order.

Frame 0: Shows a coffee machine with a cup under it. The cup is yellow, ribbed, and there's a stream of liquid (coffee) being poured. The machine has a digital display with blue circles.

Frame 1: The cup is still there, now filled with liquid, and a tea bag is visible inside. The coffee is dripping, so the action is pouring into the cup. The machine is still in the background.

Frame 2: Split screen. Left side is the cup with the tea bag, right side is a hand opening a brown paper bag with a croissant. The croissant is golden-brown, and the hand is holding the bag's tab.

Frame 3: The croissant is now being pulled out of the bag, showing more of its shape. The bag has a "WOW!" sticker, but per the rules, exclude text recognition. So focus on the action: hand removing croissant from the bag.

Frame 4: Exterior night shot of a "WOW!" store. The building has lights, a menu board, and the store name lit up. It's a night scene with the building's exterior.

Now, chronological order.

Start with the coffee machine pouring into the cup (first frames). Then the tea bag in the cup. Then split screen: left is cup with tea bag, right is hand opening the croissant bag. Then the croissant being removed. Then exterior of the store at night.

Need to describe motion: coffee pouring, tea bag in cup, hand opening bag, croissant being taken out, then the exterior shot.

Main subjects: coffee machine, cup, tea bag, hand, croissant, store exterior.

Appearance: yellow ribbed cup, dark coffee, tea bag, brown paper bag, golden croissant, illuminated store sign.

Spatial: Cup under coffee machine, hand holding bag tab, croissant inside bag, store exterior at night.

Avoid text. Camera movement: First close-up of coffee machine, then close-up of cup, then split screen (side-by-side), then close-up of hand and croissant, then wide shot of store exterior.

Need to be concise. Let's structure:

A coffee machine pours dark liquid into a yellow ribbed cup containing a tea bag. A hand opens a brown paper bag, revealing a golden croissant. The scene transitions to an exterior night view of a brightly lit store.

Wait, check rules: focus on motion and behavior in chronological order.

Frame 0: coffee machine (metal nozzle) pouring into yellow cup (initially maybe empty, but by frame 1, it's filled with liquid and tea bag). So motion: liquid dripping into cup.

Frame 1: cup with tea bag, coffee pouring. So action: coffee pouring into cup with tea bag.

Frame 2: split screen: left is cup with tea bag, right is hand opening brown bag (which has croissant).

Frame 3: hand continues to open bag, croissant being pulled out.

Frame 4: exterior night shot of the store.

So chronological steps:

1. Coffee machine dispenses dark liquid into a yellow ribbed paper cup, which contains a tea bag.

2. A hand pulls open a brown paper bag, revealing a golden croissant inside.

3. The scene shifts to an exterior night view of a store with illuminated signage.

Wait, need to check if the split screen is part of the sequence. The video cuts from frame 0-1 (coffee cup), then frame 2 (split screen), then frame 3 (croissant out of bag), then frame 4 (store exterior).

So the order is:

- Coffee machine pouring into cup with tea bag.

- Split screen: left (cup), right (hand opening bag with croissant).

- Hand continues opening bag, croissant partially extracted.

- Exterior of store at night.

Now, describing motion:

- Liquid flows from a coffee machine's nozzle into a yellow ribbed cup containing a tea bag.

- A hand opens a brown paper bag, pulling out a golden croissant.

- The scene transitions to a night exterior shot of a store building with bright lights.

Check rules: exclude text (so "WOW!" on bag or sign is not mentioned), focus on motion.

Also, spatial relationships: cup is under the coffee machine, hand is in front of the bag, store is exterior.

Now, concise paragraph.

Let's draft:

A coffee machine dispenses dark liquid into a yellow ribbed cup containing a tea bag. A hand opens a brown paper bag, extracting a golden croissant. The scene transitions to an exterior night view of a brightly lit store building.

Check if motion is covered: pouring, opening bag, extracting croissant, transitioning to exterior.

Yes

A hand stirs the contents of a cup and then opens a bag to reveal a pastry.

The background elements (coffee machine, building) are static with no significant shifting or fluid motion. No fire, water, smoke, or wind is dominant.


A group of people gathers around a white container; a woman in a striped shirt and hat assists a girl in a gray top and denim shorts to step inside, while others, including a woman in a colorful dress, stand nearby. The scene occurs outdoors with autumn-colored foliage in the background. The camera remains stationary, capturing the interaction from a frontal view.

Discrete objects (people) are moving: individuals are dancing, interacting, and shifting positions, showing explicit locomotion and physical interactions.

The background trees and foliage exhibit subtle motion, likely due to wind, indicating ambient environmental movement. However, this is secondary to the primary action.


A person wearing a black and white patterned top has a brownish substance covering their face. They raise their right hand to touch their cheek and mouth area, then speak while maintaining the substance on their face. The camera remains in a close-up position with slight movement, focusing on the upper body and face. The background includes indistinct household items. The person’s hand moves toward their face, then retracts as they continue speaking.

A person is moving their hands and head, with no other discrete objects moving.

Background (bathroom tiles, shower curtain, sink) is static; no fluid/environmental motion (fire, water, smoke, wind) observed.


A child in a black shirt holds a frying pan on the kitchen counter, then turns and walks toward the camera while lifting the pan higher. An adult in a light gray shirt works at the sink in the background. The camera slightly follows the child’s movement as he moves across the kitchen space.

A child is moving a plate (holding it, lifting it, and adjusting its position), and another person in the background is walking. Both motions involve discrete solid objects (people, plate) moving due to voluntary locomotion.

Background elements (cabinets, walls, kitchen fixtures) remain stable with no uniform shifting or fluid motion (fire, water, smoke, wind) observed.


RAW CAPTION: Got it, let's tackle this. First, I need to describe the video in chronological order, focusing on the main subjects' motions and behaviors.

Looking at the frames:

First frame: Two people, one in gray (light gray long-sleeve, dark pants) and one in white (light gray shirt, light pants). They're in a large indoor space with a colorful floor. The person in gray is kneeling, reaching out with both hands. The person in white is standing, also reaching out, maybe in a martial arts move.

Second frame: The person in gray is still, then moves to a different angle. Wait, no, the frames are sequential. Let's list the frames:

Frame 0: Two people interacting. One (gray outfit) kneeling, arms extended. The other (white) is standing, arms out. They're in a large hall with chairs in the background.

Frame 1: The person in gray (now in black with purple accents, maybe different frame) is moving. Wait, the video has 5 frames (0 to 4). Let's check each frame's description:

[0.0s]: Two people, one in gray (long-sleeve, dark pants) kneeling, extending hands; other in light gray (shirt, pants) standing, extending hands. Background has chairs, a building interior.

[1.0s]: The person in gray (now in black with purple, maybe same person) is standing, moving. Wait, the first frame shows a person in gray, but in the second frame, the person is in black. Wait, the video frames:

The first frame (0.0s) shows two people: one kneeling (gray top, dark pants), one standing (light gray top, light pants). They're interacting, hands reaching out.

Then 0.3s: Next frame (maybe 0.3s), the person in gray is standing, now in black with purple (maybe different outfit), moving. Wait, the description says:

[0.0s]: two people (kneeling, standing) in gray and light gray.

[0.3s]: one person in black (with purple accents) standing, moving arms.

Wait, the problem is that the frames are sequential. Let's parse the video description given as the input:

The video shows:

<0.0s> [0.0s] two people, one kneeling (gray top, dark pants) reaching out, the other standing (light gray top, light pants) reaching out. Background: large hall, chairs, a poster on a counter.

<0.3s> [0.3s] the kneeling person is now standing, wearing black top with purple (maybe headband or scarf), and moves arms (extended).

<1.0s> [1.0s] the person in black (with purple) is in a martial arts stance, moving.

<2.0s> [2.0s] the person in black (with purple) is moving, maybe kicking or sweeping, and another person in red appears.

<3.0s> [3.0s] the person in black (with purple) is turning, facing a person in red.

<4.0s> [4.0s] the person in black (with purple) is in a stance, interacting with person in red.

So the main subjects are two people: one (main) in black with purple accents (maybe a robe or outfit), and the other in red or other colors.

Chronological order:

First, two people (one kneeling, gray top; other standing, light gray top) interact, hands extended. Then, the kneeling person stands up, now in black with purple, moves arms. Then, this person (main) moves in a martial arts form, extending arms, then turns to face another person in red (who walks in), then the main person continues the motion, facing the red-shirted person.

Wait, the first frame (0.0s) has two people: one kneeling (gray), one standing (light gray). Then, in the next frames, the kneeling person is now standing in black with purple. Wait, maybe the person in gray is the same, but the color changes? No, perhaps it's a sequence of the same person performing moves.

Wait, the first frame shows two people: one in gray (kneeling) and one in light gray (standing), interacting. Then the scene transitions to the person in gray (now standing, wearing black with purple) performing moves, and another person in red appears.

Wait, the instruction says to focus on the motion and behavior of main subjects in chronological order.

Let me list the frames in order:

- Frame 0: Two individuals interact. One (kneeling) wears gray top and dark pants; the other (standing

Two people in the initial scene (interacting by hand movements) and one person (martial artist) in the subsequent scene (performing dynamic martial arts moves with arm and leg movements).

The background elements (walls, chairs, floor) in both scenes are static with no shifting or fluid motion. No fire, water, smoke, or wind is present.


The video opens with a white plate holding sliced cucumbers, tomato slices, and a whole cucumber on a light countertop. Next, a person with dark sleeves places sliced tomato pieces onto two open-faced sandwiches, each layered with ham and cheese on buns. The hands move from the plate to the sandwiches, adding ingredients, with the vegetable plate positioned to the right. The camera remains close-up and steady, focusing on the hands and sandwiches during assembly.

Discrete solid objects (hands, vegetables, sandwiches) move as the person places cucumber and carrot slices on open-faced sandwiches.

The background (kitchen counter, bottles) remains static with no shifting or fluid motion; no fire, water, smoke, or wind present.


A person holds a small dark circular object with their right hand, moving it toward their right eye, then positions the object on the eye's surface. The camera maintains a close-up view of the face throughout, with no visible movement.

The person's hand and makeup brush are moving in a controlled manner to apply eye shadow.

Static background with bookshelves; no shifting or environmental motion (fire, water, wind).


A person in a gray shirt, wearing a headlamp, sits while working on a tube. Their hands hold the tube, then use sandpaper to roughen its surface. The camera shifts from a medium shot of the person to close-ups of the hands sanding the tube’s length.

The person's hands and a small tool/object are moving, with discrete interactions (e.g., manipulating materials, adjusting positions) indicating physical motion.

The background elements (e.g., workspace, clothing) remain stationary with no fluid or environmental motion (fire, water, wind) observed.


RAW CAPTION: Got it, let's break this down. First, the video starts with a person in a blue shirt using a long tool with a blue handle to clean windows. The tool is probably a squeegee or something for cleaning. The windows are part of a building with plants along the windowsill. Then there's a transition to a person in a light blue polo shirt standing against a white background. Wait, the rules say to focus on motion and behavior chronologically.

So first scene: a person (wearing blue) is cleaning windows with a long tool. The action is moving the tool across the window. Then the scene changes to another person (light blue shirt) standing, maybe speaking. But we need to describe chronological order.

Wait, the first part: the person is holding a long tool with a blue curved end, cleaning the window. The windows have plants on the sill. Then the scene shifts to a person in a light blue polo shirt against a white background. Wait, the video starts with the cleaning, then cuts to the person.

Wait, let's check the frames:

[0.0] shows a person in blue shirt, tool, cleaning window. The background has plants, building. Then [5.0] is a white background with the person in light blue polo.

So chronological order: first, the person in blue is cleaning the windows with a long tool (blue head), moving it across the glass. Then, the scene transitions to a person in a light blue polo shirt standing against a white background.

Need to mention appearance: person in blue shirt (first scene), then light blue polo (second scene). Motion: the first person is using the tool to clean the window, moving it. Then the second scene is a static shot of the person standing.

Also, spatial: in the first scene, the person is in front of the building with windows and plants. Second scene is against white background.

Camera movement: the first scene is a top-down or angle shot of the cleaning, then the second scene is a straight shot of the person.

Wait, the rules say "conclude with camera perspective and movement". So first part: camera shows person cleaning windows (maybe slight angle), then cuts to a static shot of the person in white background.

Let me structure:

In the initial segment, a person wearing a blue shirt uses a long-handled tool with a blue curved end to clean a window, moving the tool across the glass surface. The windows feature a white frame and plants along the sill. The scene then transitions to a person in a light blue polo shirt standing against a plain white background. The camera maintains a top-down perspective during the cleaning sequence and shifts to a static shot for the person against the white backdrop.

Wait, but need to be concise. Let's check rules: "concise, chronological paragraph".

First part: person (blue shirt) uses tool (blue curved handle) cleaning windows (motion: moving tool). Then, transition to person (light blue polo) standing against white background.

Also, background in first scene: windows with plants, building. But rule f: exclude text recognition, but background descriptions minimal unless essential. The plants are along the sill, so maybe necessary to understand the setting.

Wait, the main subject is the person cleaning. So:

A person in a blue shirt cleans a window with a long tool having a blue curved head, moving it across the glass. The window has a white frame with plants along the sill. The scene then cuts to a person in a light blue polo shirt standing against a plain white background.

Camera: in the first part, camera is positioned to show the cleaning action from an elevated angle; the second part is a static shot of the person.

Wait, the first frame: the person is on a deck, so maybe the camera is at a slight angle, top-down.

Let me make it concise.

In the opening, a person wearing a blue shirt uses a long-handled tool with a blue curved end to scrub a window, moving the tool across the glass. The window features a white frame and plants along the sill. The scene then transitions to a person in a light blue polo shirt standing against a white background. The camera maintains a top-down perspective during the cleaning sequence and shifts to a static shot for the person in the white backdrop.

Wait, need to check if "scrub" is accurate. The tool is being moved, so "cleans" or "scrubs".

Also, number: only one person in each scene.

Let me check the rules again:

a) Motion and behavior in chronological order.

b) Appearance and number: blue shirt, long tool with blue head (one person). Then light blue polo (one person).

c) Spatial: in the first scene, person is in front of the building with windows and plants. In second scene, against white background.

d) Conclude with camera perspective: first part,

The person in blue (wearing a blue shirt and gloves) is actively moving the hose across the glass window to clean it. The motion of the person and the hose is distinct and can be tracked with a bounding box.

The background (rooftop railings, glass panels, and distant buildings) remains stationary throughout the clip. The water spray is a controlled, localized fluid motion that is not dominant; it is a byproduct of the person's cleaning action and does not constitute the primary motion.


A man in a black traditional jacket with white trim and white shoes stands on a paved path surrounded by green grass and trees. He bends forward, adjusts his shoes, then stands upright. The camera maintains a steady medium shot throughout the sequence.

A single person (the man) is performing a series of bending and kneeling movements. The motion is discrete and solid, tracked via bounding box.

Background consists of stationary trees and grass; no fire, water, smoke, or wind motion detected. Trees are still, indicating no significant ambient environmental movement.


A gloved hand in black uses a spray can to apply red paint on a white wall, forming curved graffiti shapes with smooth, continuous motions. The hand moves fluidly across the surface, extending the design. The camera maintains a top-down close-up perspective, focusing on the hand's movement and the evolving artwork.

A person's gloved hand holding a spray paint can moves systematically to write graffiti ('FROG') on the surface. This is a solid, distinct object (hand and can) moving due to explicit physical forces (arm motion).

The background (white surface with graffiti) remains static throughout; no fluid/environmental motion (e.g., fire, water, smoke) is present. Background elements show no uniform shift.


A person wearing white over-ear headphones and a dark shirt with a circular logo gestures toward their chest with their right hand, then brings their hand to their face. The camera then shifts to a close-up of the person's eye as they touch their eye with their finger. The background features wooden cabinets, and the camera perspective transitions from a medium shot to a tight close-up.

A person wearing headphones is seen making deliberate hand gestures (adjusting headphones, touching face), with movements localized to the upper body and hands.

No significant shifting background or fluid/environmental motion observed. Background elements (wooden cabinets, wall decorations) remain static throughout the sequence.


tags. So the final sentence.  Let me try again.  The video starts with a person in a white shirt moving inside a car. Then a person in a checkered shirt is shown, then the white shirt person again. The camera is shaky, moving between them.  So: "Two people are seated inside a vehicle; the individual in a white shirt moves forward, then the person in a checkered shirt shifts position, with the camera capturing their actions through shaky handheld movements and shifting focus between the two."  Yes, that's chronological, mentions appearance, number, motion, camera movement. Background is car interior, but not emphasized as per rule e. </think>  <caption_output>Two individuals are seated inside a car; the person in a white shirt adjusts their position, followed by the individual in a checkered shirt moving within the seat, captured by a handheld camera with slight shakes and shifts in focus between the subjects.

Two people in a vehicle: person in white shirt shifts position, adjusts clothing, and moves arms; person in patterned shirt gestures and repositions body.

No shifting background elements; interior of a vehicle with static seats and windows visible. No fire, water, smoke, or wind present.


A hand holding a bouquet of purple, orange, and white flowers enters the frame, moving downward to place the arrangement into a clear glass vase containing a single pink tulip, displacing the tulip. The vase sits on a white surface with metallic objects nearby, while the background remains blurred. The camera remains stationary, capturing the motion from a fixed overhead perspective.

A human hand (solid object) moves to place a bouquet of flowers into a glass vase, with the bouquet's position changing due to explicit physical interaction.

Background elements (chairs, plants) show no uniform shifting; no fire, water, smoke, or wind effects present.


A person in a light gray shirt and brown shorts stands inside a room, using a trowel to apply material to the wall before touching the wall to check its smoothness; outside the window, another person in a light-colored top and dark pants stands near the railing, observing. The camera remains stationary, capturing the scene through the window.

A person is moving: initially bending near the wall (0.0-1.0s), then standing and using a brush/tool on the window frame (1.3-5.0s). Motion is localized to the person's body and arm movements.

No shifting backgrounds or fluid/environmental motion observed; interior walls and window view (including distant brick wall) remain static. No fire, water, smoke, or wind present.


tags.  So, let's draft: "A person wearing light-colored gloves hammers a metal piece on a large anvil, then sets aside the hammer. The scene transitions to two men, one in a dark blue sweater and beige pants, the other in a dark shirt and shorts, bending over to adjust a white horse’s reins on a concrete surface. The camera starts with a close-up of the anvil work, then shifts to a medium shot of the men and horse, showing their interaction." </think>  <caption_output>A person wearing light-colored gloves hammers a metal piece on a large anvil, then moves the hammer aside. The scene transitions to two men, one in a dark blue sweater and beige pants, the other in a dark shirt and shorts, bending over to adjust a white horse’s reins on a concrete surface. The camera starts with a close-up of the anvil work, then shifts to a medium shot of the men interacting with the horse.

Two segments: (1) A person manipulates a metal object with a hammer, causing the metal to bend; (2) Two men work on a large white object, using tools to shape it. Both involve distinct solid objects moving due to applied forces.

The background in both segments (concrete ground and outdoor structures) is static with no significant shifting or fluid motion. No fire, water, or wind is visible as dominant motion.


The video begins with a top-down view of waxing supplies—cotton rounds, curved scissors, wax sticks, tweezers, and an angled brush—arranged on a white, textured surface. It transitions to a close-up of a person lying on their back, wearing a camouflage-patterned top, as a hand with light blue nail polish uses an angled brush to apply a product near their forehead and then wipes the area with a cotton pad. The camera remains static during the supply display and shifts to a close-up for the procedure.

The hands of the person applying the product and the face of the recipient are moving. The hands are applying a substance to the face, with movements such as pressing and wiping. These are discrete objects moving due to explicit physical forces (application process).

Initial frames show a static background of art supplies. The subsequent scene features a static bed background with no uniform shifting. No fluid motion (fire, water, smoke) or environmental wind is present.


The video shows a cutting table with two metal trays on a blue surface: one tray holds halved yellow potatoes, the other whole yellow potatoes. A gloved hand moves into the frame, placing a halved potato into the cut potato tray. The camera zooms in to focus on the trays, showing the arrangement of potatoes as the hand adjusts their positions. Perspective shifts to a close-up of the potatoes and hand movements.

Potatoes are moving along a conveyor belt; hands with blue gloves briefly adjust potatoes at the start, but the dominant motion is the continuous flow of potatoes driven by the conveyor system.

No shifting background or fluid/environmental motion; background elements (blue trays, factory walls) remain static throughout. No fire, water, smoke, or wind visible.


A toddler in a pink top and bright pink pants pushes a large silver shopping cart forward with both hands, gripping the handle and shifting weight to move the cart slowly across a light blue and white tiled floor. The cart contains a pink bag and other items. Viewed from a top-down angle with minimal camera movement.

A baby (solid object) is pushing a shopping cart (solid object). The baby's locomotion and pushing force cause the cart to move.

The background (supermarket floor and walls) shows no shifting or uniform motion. No fire, water, smoke, or wind present. Static environment.


A person in a black helmet and orange-tinted goggles, dressed in dark gear, is inside a helicopter. They reach for the open door, exit the aircraft, and begin freefalling with arms extended. The camera captures the transition from inside the helicopter to the person airborne, showing their descent against the sky. The camera starts inside the helicopter, follows the person exiting, then shifts to a view from the helicopter's interior as the individual falls.

The person wearing a helmet and goggles is the discrete object, transitioning from inside the aircraft to freefall. Their motion is driven by gravity and parachute deployment, representing clear physical locomotion.

The background includes the aircraft interior and distant sky/ground. There is no dominant fluid/environmental motion (e.g., fire, water, smoke, wind) controlling the scene; the sky features subtle cloud movement but lacks sufficient fluid dynamics to dominate the visual.


RAW CAPTION: Got it, let's tackle this. First, the video starts with a close-up of a pot on a stove. A hand is stirring the contents with a wooden spoon. The pot is black, on a white electric stove. The background has tiled walls and a countertop. Then, the scene cuts to a wider shot where a person in a green shirt stands near the counter. They have a plate with food and a cutting board. Let's check the rules. Need to describe motions chronologically.

First part: hand stirring in the pot. The pot is on the stove, steam rising. Then the scene changes to a person in a green shirt at the counter. The main subjects are the hand stirring, then the person standing. Appearance: hand holding spoon, dark sleeves, green shirt. Spatial: pot on stove, person near counter. Background: tiled wall, countertop. Camera movement: first close-up, then wider shot. Wait, the video transitions from close-up of pot to a wider view. So need to mention that. Also, the rules say minimal background unless essential. The first scene: pot on stove, hand stirring, steam. Then second scene: person in green shirt, standing at counter with items. Let's structure it.

Chronological: First, a hand stirs a yellowish mixture in a black pot on a white electric stove. The pot emits steam. Then the camera shifts to a wider view showing a person in a green shirt standing near a countertop with various items. The person holds a plate and a cutting board with vegetables. Camera starts close-up on pot, then moves to a wider angle. Wait, the output must be a paragraph. Let's check example.

Wait, the user says "concise, chronological paragraph". So first action: hand stirring pot. Then the scene changes to the person. Let's write:

A hand with a wooden spoon stirs a bubbling, yellowish mixture in a black pot on a white electric stove; steam rises from the pot. The camera then shifts to a wider angle, revealing a person in a green shirt standing at a countertop with a plate and a cutting board containing vegetables, positioned to the left of the stove.

Wait, need to check rules. "Briefly describe their appearance and number". The hand: dark sleeve (since the person's arm is visible, dark clothing). The person: green shirt. "Mention spatial relationships". The pot is on the stove, person is at counter to the left of stove. "Conclude with camera perspective and movement": starts close-up on pot, then shifts to wider angle. Background: tiled wall, countertop, but minimal. "Exclude text recognition" — no text visible. So:

In the opening scene, a hand with dark clothing stirs a bubbling yellow mixture in a black pot on a white electric stove; steam rises from the pot. The camera then transitions to a wider view, showing a person wearing a green shirt standing near a countertop with a plate and a cutting board of vegetables, positioned to the left of the stove. The perspective shifts from a top-down close-up of the pot to a broader overhead angle encompassing the person and counter.

Wait, but the second scene: the person is in front of the counter. Let's check the video: the second frame shows "a person in a green shirt standing at the counter, holding a plate and a cutting board with vegetables". So "standing at a countertop with various items (plate and cutting board)". So maybe:

A hand wearing a dark sleeve stirs a yellowish, steaming mixture in a black pot on a white electric stove. The camera then shifts to a wider angle, revealing a person in a green shirt standing at a countertop with a plate and a cutting board of vegetables, positioned to the left of the stove. The perspective moves from a close-up of the pot to a broader overhead view of the kitchen area.

Wait, the rules say "keep background descriptions minimal unless essential". The first part: tiled wall is background, but maybe not essential. The stove and pot are key. Let's focus on motion and behavior. The first action: stirring. Then the camera changes to show the person. Let's make it concise.

First, a hand stirs a bubbling yellow mixture in a black pot on a white stove. Steam rises as the spoon moves. The scene then cuts to a person in a green shirt standing at a counter with a plate and cutting board, near the stove. The camera shifts from a close-up of the pot to a wider shot of the person and kitchen.

Wait, check the rules again. "Conclude with camera perspective and movement (e.g., top-down, pan left, slight shake)". The first part is top-down close-up on pot, then the second scene is probably a wider angle (not necessarily top-down, but the video's second frame shows a person standing

A person's hands and a spoon stirring contents in a pot on a stove; discrete solid objects (spoon, pot, hands) exhibit motion due to explicit physical force (stirring).

Static tiled wall and countertop with no shifting or environmental fluid motion (no fire, water flow, smoke).


RAW CAPTION: Got it, let's break down the video. First, the first frame shows a person in black running in an urban setting. Then, the scene shifts to two individuals dancing; one in a black tank top with "WALK" visible, another in a black hoodie. Next, a crowd of people, some in yellow shirts, are dancing energetically. Then, a person in black is moving outdoors with a crowd in the background. Finally, three people in white shirts are dancing in a line. The camera moves between these scenes, each time focusing on dancers. Need to describe chronologically, mention appearance, motion, then camera. Keep it concise, no text, names. Let's structure it:

Start with the runner: "A person in black attire runs across an urban background. Next, two individuals dance; one wears a black tank top with visible text, the other a black hoodie. Then, a large crowd in yellow and other colored shirts dances energetically. A person in black moves through an outdoor setting with a crowd behind. Finally, three people in white shirts dance in a line. The camera shifts between these scenes, capturing dynamic movements from various angles."

Check rules: chronological, motion, appearance (color, size), spatial? Maybe minimal. Background minimal. Exclude text recognition (like "JAM OF THE WEEK" isn't mentioned since rule f says exclude text). Wait, rule f says exclude text recognition, named characters, stylistic analysis. So even if text is visible, don't mention. So in the video, there's text like "JAM OF THE WEEK" but we ignore that. So focus on people. Let's rephrase:

First clip: person in black runs. Second: two dancers, one with black tank top, one with black hoodie. Third: crowd dancing (yellow shirts among others). Fourth: person in black outdoors. Fifth: three in white dancing.

Make it a paragraph. Check order. Ensure each step is chronological.

"A person in black runs through an urban environment. Two dancers appear, one in a black tank top and another in a black hoodie, performing energetic movements. The scene transitions to a crowd of dancers, some wearing yellow shirts, moving rhythmically. Next, a person in black moves through an outdoor area with a large crowd in the background. Finally, three individuals in white shirts dance in a line. The camera captures these sequences with varying perspectives, panning and shifting focus between the dancers."

Check rules: a) motion and behavior chronological. b) appearance: color, size, orientation. So "person in black" (color), "two dancers, one in black tank top, another black hoodie" (colors, what they're wearing). c) spatial relationships: maybe "in front of" for the crowd, but rule c says mention if relevant. In the crowd scene, they're together. Maybe minimal. d) camera perspective: "pans and shifts focus". e) background minimal: urban environment, outdoor area. f) exclude text, so no mention of "JAM OF THE WEEK" etc. g) internal thinking, no reasoning.

Let me check the examples. Let's see:

First frame: person in black running, background urban (wall, pipes). Second: two people dancing (one with "WALK" but we don't mention text), so "one in black tank top, other in black hoodie". Third: crowd dancing, some yellow shirts. Fourth: person in black moving outdoors, crowd behind. Fifth: three in white shirts dancing.

So the paragraph should list each scene in order:

1. A person in black runs across an urban setting.

2. Two dancers are seen: one in a black tank top, the other in a black hoodie.

3. A large group of dancers, including those in yellow shirts, move energetically.

4. A person in black walks through an outdoor area with a crowd in the background.

5. Three individuals in white shirts dance in a line.

Camera: "The camera shifts between these scenes, capturing dynamic movements from different angles."

Combine into a paragraph:

"A person in black runs through an urban environment. Two dancers, one in a black tank top and the other in a black hoodie, perform energetic movements. A crowd of dancers, some in yellow shirts, dances together. Next, a person in black moves through an outdoor setting with a large crowd behind. Finally, three individuals in white shirts dance in a line. The camera captures these sequences with shifting perspectives and pans between the dancers."

Check for minimal background: "urban environment" and "outdoor setting" are minimal. No text, no names. Okay.
</think>

<caption_output>A person in black runs through an urban environment. Two dancers, one in a black tank top and the other in a black hoodie, perform energetic movements. A crowd of dancers, some in yellow shirts, dances together. Next, a person in

Discrete solid objects (people) are moving due to locomotion (dancing) in multiple scenes.

Background elements (walls, ground, trees) are static and show no signs of shifting or fluid motion (fire, water, smoke, wind).


A pair of hands manipulates a thin orange string, initially holding it between fingers, then stretching it taut and looping it. The background features a grassy outdoor area. The camera remains in a close-up perspective with minimal movement.

Discrete solid objects: Two hands manipulating a thin wire/string. Motion involves bending, twisting, and stretching due to manual force application.

Background (grass and green object) shows no uniform shifting or fluid motion; no fire, water, smoke, or wind evident. Static elements remain consistent across frames.


A pair of hands manipulates small metal chain links on a cluttered workbench, using tweezers and pliers to weave the chain. The hands move rhythmically, picking up links, positioning them, and interlocking them. Various tools—including a blue-handled tool, orange-handled pliers, and a screwdriver—lie scattered across the table, with metal fragments nearby. The camera maintains a steady top-down perspective throughout, focusing closely on the hands and immediate workspace.

Discrete solid objects: hands manipulating pliers and metal chain pieces. Movement involves precise manual handling of jewelry-making tools and materials.

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


A shirtless baby with light brown hair sits in a green mesh high chair, facing a white tray with scattered food crumbs. The baby looks down at the crumbs, then reaches their right hand toward them, gently touching the food particles. The camera remains stationary, capturing the scene from a close, slightly overhead angle without significant movement.

The baby (discrete solid object) exhibits localized movements: head turns, gaze shifts downward, and hand reaches toward food crumbs on the tray.

Static background elements (wall, window) show no uniform shifting. No fire, water, smoke, or wind detected; ambient motion is absent.


A hand with dark nail polish places a small pink toy dinosaur with one large eye on a wooden surface, then adjusts its position. The hand moves the toy slightly across the table, reorienting it while keeping it as the central focus. The camera maintains a close-up perspective with minimal movement, capturing the toy’s motion against a blurred background of a tiled floor and indistinct objects.

A human hand (discrete object) physically pushes a pink toy fish (discrete object) across a table. The fish's motion is directly caused by contact force from the hand, showing clear object-to-object interaction.

The background elements (tiled floor, clock) remain stationary with no uniform shifting or environmental motion (fire, water, smoke, wind). Background stability confirms no ambient environmental effects.


A pair of black-gloved hands interacts with a red and white patterned object on a blue tarp. The scene transitions to a girl in a gray shirt and shorts crouching beneath red-seated chairs on grass, retrieving a red object from under the chairs and standing. The camera shifts from top-down to a ground-level perspective.

A person (wearing gloves in first segment, gray top/shorts in second) manipulates a solid pink/red object. The object is lifted, carried, and moved by hand; the person's locomotion (bending, standing, walking) is the primary discrete action.

In the first segment, the blue tarp background is static with no environmental motion. In the second segment, the brick building and grass background remain fixed with no wind-induced sway or fluid motion (e.g., no waves, smoke, or fire). No dominant ambient environmental phenomena are present.


A hand wearing a blue and white striped sock enters the frame, moving across a handwritten note from left to right while pointing at specific sections. The camera maintains a close-up perspective with slight shakiness, focusing on the hand’s motion over the paper. The hand’s orientation shifts as it traces the text, with the sock’s striped pattern visible against the paper’s surface.

A hand (with a blue and white striped sleeve) is moving across the paper, tracing handwritten text.

The background is the paper with text, which is stationary. There is no fire, water, smoke, or wind. The ambient motion is minimal and not dominant.


A person with curly light brown hair and wearing a white shirt sits in the driver's seat of a maroon interior car. The individual raises their right hand in a waving motion, then moves it in a gesturing manner. The camera maintains a static front-facing perspective throughout the sequence.

A person is making hand gestures and adjusting hair, with movements of the hands and head being the primary discrete object motion.

Background shows static trees and no fluid motion (e.g., fire, water, wind). No shifting background elements.


RAW CAPTION: Got it, let's tackle this. The video is a surveillance clip. First, look at the main elements. There's a white car parked, some stacks of tires or barrels, and a person running. Let's check the timestamps: 0:00 to 0:05. At 0:02, a person enters the frame from the right, runs towards the left, then exits. The background has buildings, cars, and crates. The camera is top-down, fixed. So need to describe the person's motion: appears from right, runs left, disappears. The white car is stationary. Mention spatial relationships: person runs past the car? Wait, the car is in the middle. Let's see the frames. The person starts at the top right (since it's a top-down view), runs left, passing the white car? Wait, the white car is in the lower left part. Wait, the video shows the person coming from the top right, moving left, passing the white car, then going out of frame. Let's check the timestamps. At 0:01, no person; 0:02, person appears on the right; 0:03, running left; 0:04, still running left; 0:05, maybe exiting. So the sequence: a person (dark clothing, can't tell size, but human) enters from the upper right, runs diagonally leftward, passes the white car (which is parked), then exits the frame. Background has structures, but minimal. Camera is fixed top-down. Need to be concise. Let's structure: In the surveillance footage, a person in dark clothing enters from the upper right, runs leftward across the frame, passing a stationary white car, and exits the scene by 0:05. The camera maintains a fixed top-down perspective throughout, with minimal background elements including stacked items and vehicles. Wait, but need to follow rules: focus on motion and behavior. So main subject is the person. Number: one. Appearance: dark clothing (since not specified, but from video). Motion: enters right, runs left, exits. Spatial: runs past white car. Background minimal. Camera top-down, no movement. Let's draft: A person in dark clothing runs from the upper right to the left side of the frame, passing a white car parked near stacked red and white barrels, then exits the scene by 0:05. The camera remains fixed top-down with no movement, capturing the area with minimal background details. Wait, check the background: in the first frame, there's a red structure, maybe a building, and other vehicles. But rule e says minimal background unless essential. The car is essential as a reference. So "passes a white car" is okay. Let's check if the person's direction is clear. From the video, the person moves from the right side (top right in the frame) to the left, so leftward. The car is in the lower left part, so the person runs past it. Yes. So the caption should be chronological: at the start, no person; then person appears, runs left, exits. So: In the top-down surveillance footage, a person wearing dark clothing enters the frame from the upper right, runs leftward across the scene, passes a white car parked near stacked items, and exits the frame by the fifth second. The camera remains stationary with a fixed top-down perspective throughout, showing minimal background elements. Wait, but rule f says exclude text recognition, which is already done. Also, check if the car is the main object. The main subject is the person. So focus on person's motion. Let's make it concise. "A person in dark clothing runs from the upper right to the left side of the frame, passing a stationary white car, then exits the scene. The camera maintains a fixed top-down view with no movement." But need to mention the time frame? No, the caption is chronological paragraph. The video is 5 seconds. So: At 0:02, a person in dark clothing enters the upper right of the frame, runs leftward across the scene past a white car, and exits the frame by 0:05. The camera is fixed top-down with no movement, capturing the area with minimal background details. But rule a says chronological order, so start from when action begins. The person appears at 0:01 or 0:02? The timestamp in the video: 10:34:45:88 on 08/01/2011. The frames: [0.0] to [5.0]. The person appears at frame 1 (0.5s?), but the timestamps show 10:34:45:88 to 10:

A single person walks across the frame from the top-right to the bottom-left, moving at a consistent pace. The person is the only discrete solid object exhibiting motion, with no other moving objects or environmental effects.

No shifting backgrounds or fluid/environmental motion observed. The building structures, parked cars, and ground remain static throughout the clip. No fire, water, smoke, or wind effects are present.


A person in a blue jacket and black cap works on a brick structure, placing bricks with hands and tools. The individual moves to adjust bricks on the wall, then the camera shifts to a wider view of the bricklaying area with spectators in the background. The scene transitions to the person continuing bricklaying near stacked bricks and equipment, with the camera capturing the workspace from a frontal perspective.

The primary discrete objects are the person in blue handling bricks and the bricks themselves, moving due to physical forces (lifting, arranging) during the construction event.

No significant fluid or environmental motion (e.g., fire, water, smoke, wind) is observed. Background elements (event structure, spectators, arena walls) are static and do not exhibit uniform shifting.


A person in a gray shirt with a silver wristwatch sits at a table with a white surface featuring blue and green floral patterns. They eat a piece of food, using both hands to peel and consume it while peels and scraps accumulate on the table. The camera remains static, capturing the upper body and table from a frontal perspective with minimal background details.

A person is peeling a yellow fruit (likely lemon) with their hands. The hands and fruit are moving in discrete, solid motions.

Background is stable with no shifting elements. No fire, water, smoke, or wind visible.


Two children, one in a blue shirt and white hat, the other in a gray shirt and red shoes, walk together on a sidewalk. The blue-shirted child extends his hand, then they approach a wooden fence where a white and brown goat stands. Both children reach out to touch and pet the goat. The camera follows them with a slight shake as they move toward the animal.

Two boys (one in blue shirt/hat, one in gray shirt/red shoes) and a goat are moving. The goat shifts its head/body within the pen while eating, and the boys reach toward it; both movements are due to voluntary locomotion and interaction.

The background includes paved ground and a fence with occasional pedestrian movement, but no fire, water, smoke, or wind. Static elements (like the fence and ground) show no uniform shifting, indicating minimal ambient environmental motion.


A person in a dark shirt, light pants, and helmet descends a rocky cliff using a yellow rope, moving steadily downward. Below, two individuals wearing blue and black helmets observe. The camera maintains a top-down perspective with slight movement, capturing the climber’s descent against the rocky terrain.

A person is descending a cliff via rappelling, with other individuals visible at the base of the cliff.

Background consists of stationary rocks and vegetation; no fluid motion (fire, water, smoke) or significant wind effects observed.


A pair of hands manipulates a silver metallic seatpost, inserting it into a green bicycle frame by guiding it downward. The hands adjust the seatpost's position within the frame, ensuring proper alignment. The camera maintains a close-up perspective throughout the insertion process, keeping the background out of focus.

A hand is manipulating a bicycle seatpost, performing a mechanical insertion action. The seatpost and hand are discrete solid objects exhibiting motion due to physical manipulation.

Background is blurred with no uniform shifting; no fluid/environmental motion (fire, water, smoke, wind) present.


A person wearing an orange cap and plaid shirt holds a small blue and white object near their mouth, adjusting their hands to play it. The individual remains stationary in front of an open closet filled with hanging clothes and a door with ties, while a framed picture is visible on the wall behind them. The camera maintains a steady, frontal perspective throughout.

The person is moving their hands to play a harmonica, which is a solid object motion due to explicit physical forces (blowing air and finger movements).

The background (closet, clothes, picture) is static; no fluid or wind motion observed.


A man in a gray t-shirt stands in the foreground, raising his right hand to his shoulder, then extending both hands upward with index fingers pointing, followed by lowering his right hand. Behind him, a person in a black shirt walks past a desk, while another individual in a gray shirt sits at a desk. The camera remains static throughout.

The main subject (man in foreground) moves his arms and body (gesturing, adjusting shirt). A person in the background walks out of the frame.

No shifting background elements. No fire, water, smoke, or wind.


A green forklift, driven by a person in a dark shirt and shorts, moves forward from near an open-back gray truck toward a building's garage door, transporting a tall stack of white, rectangular bundles secured with blue straps. A second identical stack rests on a blue pallet to the left of the forklift. The camera remains stationary.

A green forklift is moving slowly in the scene; it is a solid, discrete object undergoing locomotion.

Background elements (brick wall, ground, loading dock structure) remain static with no discernible shifting or fluid motion (fire, water, smoke, wind).


The video begins with three golden-brown, grilled chicken thighs in a black speckled frying pan. A hand uses tongs to flip one chicken piece, then covers the pan with a metallic lid. After covering, the lid is removed, revealing the cooked chicken pieces resting in the pan. The camera transitions from a close-up of the pan to a top-down view of the wooden surface during the lid placement.

Chicken pieces are flipped using a spatula, showing explicit physical interaction (spatula applying force to move chicken).

The wooden surface and pan are static with no uniform shifting; oil splashing is minor fluid motion but not dominant.


A person in a black shirt with red accents holds a light-colored wooden cabinet drawer open, using their left hand to stabilize it while their right hand moves inside the drawer to adjust or place items. The cabinet, featuring empty shelves, stands to the left of the person. The camera remains stationary throughout the sequence.

A person's hands interacting with a drawer (opening, placing items, closing), showing discrete solid object motion via explicit physical actions.

Background elements (shelves, wall) are static with no uniform shifting; no fire, water, or fluid motion observed.


RAW CAPTION: Got it, let's tackle this. First, I need to describe the video chronologically. Let's look at the frames.

In the first frame, there's a man in a brown sweater shaking hands with a girl in a light blue coat. Other kids are around: a boy in blue jacket, another in dark clothes. Then the next frame, the man moves his hand up, maybe high-fiving? The girl in blue is still there. Then the boy in blue jacket steps back, the man in brown is now facing away. The girl in blue turns, maybe to the right. Then the boy in blue jacket moves further back, the man in brown stands still. Wait, need to track movements step by step.

Main subjects: the man in brown sweater, the girl in light blue coat, the boy in blue jacket, and maybe others. Let's list their actions in order.

Start: Man in brown sweater (left) shakes hand with girl in light blue coat (center). Boy in blue jacket (right) is nearby. Then, man moves his hand up towards the girl's head (maybe high-five), then the boy in blue jacket steps into the space, and the man turns to the right, the girl turns away. Wait, frame 1: hand shake. Frame 2: man's hand is up, maybe high-five, girl is still there. Then frame 3: man steps back, girl turns, boy in blue jacket is next to her. Frame 4: man is further back, girl is facing away from him, boy is behind her. Wait, maybe the sequence is: man shakes hand with girl, then he moves his arm up (like high-five), then the boy in blue jacket steps towards the man, and the girl turns away. Let's check each frame.

Frame 0: Man (brown sweater) shakes hand with girl (light blue coat). Boy (blue jacket) is to the right of girl, standing close. Another person in black (woman?) is behind the boy. Frame 1: Man moves his hand up, high-five gesture with girl. Girl is still there, boy in blue jacket is still there. Frame 2: Man's hand is down, maybe the high-five is done. The boy in blue jacket moves slightly, and the girl turns to the right. Frame 3: Man steps back, girl is now facing away from man, boy is next to girl. Frame 4: Man is further left, girl has turned to her right (away from man), boy in blue jacket is behind her.

So chronological order: The man in a brown sweater shakes hands with a girl in a light blue coat, then raises his hand in a high-five motion above her head. The girl turns away, and the boy in a blue jacket steps back, moving slightly to the right. The man then steps to his left, while the girl continues to turn away from him. The camera remains static, capturing the scene from a medium distance.

Need to mention appearances: man in brown sweater (size medium), girl in light blue coat (medium), boy in blue jacket (medium). Spatial relationships: man is to the left of the girl initially, then moves left. Boy is to the right of the girl. Girl turns away.

Background: there are other children and tables, but minimal description.

Check rules: focus on motion, chronological, appearance, spatial, camera.

Let's draft:

A man in a brown sweater shakes hands with a girl in a light blue coat, then raises his hand above her head in a high-five motion. The girl turns away, and a boy in a blue jacket steps back to her right. The man steps left, and the girl continues to turn away from him. The camera remains stationary, capturing the scene from a medium perspective.

Wait, need to be concise. Let's check each part.

Chronological:

- Start: man (brown sweater) shakes hand with girl (light blue coat).

- Then: man raises his hand (high-five), girl remains.

- Then: girl turns away, boy (blue jacket) steps back.

- Then: man steps left, girl continues turning.

Check the frames. Frame 0: handshake. Frame 1: man's hand up, high-five. Frame 2: girl turns away. Frame 3: boy steps back, man is left. Frame 4: man further left, girl turned.

So maybe:

A man in a brown sweater shakes hands with a girl in a light blue coat, then lifts his hand for a high-five above her head. The girl turns away, and a boy in a blue jacket steps back to her right. The man then moves left, while the girl continues to face away.

Camera: static, medium distance.

Yes, that's the flow.

Children and adults exhibit discrete movements: handshakes, arm gestures, and walking interactions between individuals (e.g., the man in brown shaking hands with a child, the boy in blue moving his head, and the man in black bending to interact with children).

The background wall pattern and furniture remain static throughout the clip; no fluid motion (fire, water, smoke) or environmental wind effects are observed.


A gray industrial machine with an open compartment is shown. A person's hands, wearing a dark sleeve, insert a stack of white paper into the machine's feed area. The hands guide the paper forward, positioning it within the machine's interior. The camera maintains a close-up, steady view of the machine and the paper insertion process.

Hands and a rectangular object (paper or document) are moving: hands place/adjust the object into the machine, then manipulate it, with the object moving through the machine's internal mechanism.

Background elements (machine parts, structural components) show no uniform shifting or fluid motion (e.g., no fire, water, wind); static environment with no environmental fluid dynamics.


tags.  Now, let's refine:  A person in a light blue shirt and light blue jeans sits on a rock, strumming a dark acoustic guitar. The individual’s hands move rhythmically over the guitar’s strings and fretboard. The background includes a grassy hill and clear blue sky. The camera maintains a static low-angle perspective.  Wait, "strumming" is part of the motion. Also, check if the guitar is acoustic, yes. The strap is there but maybe not necessary unless essential. The rules say "appearance and number (color, size, orientation)"—guitar is dark, acoustic, orientation vertical (since held upright).  Also, the person is seated, so "sits on a rock".  Let me check if I missed anything. The rules say "briefly describe their appearance and number"—so the person is one, wearing light blue shirt and jeans, guitar is dark acoustic.  Okay, final version:  A person in a light blue shirt and light blue jeans sits on a rock, strumming a dark acoustic guitar. The individual's hands move rhythmically over the guitar’s strings and fretboard, which is held vertically. The background features a grassy hill under a clear blue sky. The camera remains stationary in a low-angle perspective.  Wait, "stationary" instead of static? Maybe static is better. Also, "under a clear blue sky" or "with a clear blue sky".  Check if "guitar’s strings and fretboard" is correct. Yes.  Also, chronological: the action starts with sitting and playing, so the sequence is sitting → playing.  Yes, that's the main behavior.  I think that's concise. Let's make sure all rules are met.  a) Motion: playing guitar, hands moving.  b) Appearance: light blue shirt, jeans, dark guitar.  c) Spatial: sits on rock, hill behind.  d) Camera: static low-angle.  e) Background minimal: grassy hill, blue sky.  f) No text, no names.  g) Internal thought, no reasoning.  Okay, looks good. </think>  <caption_output>A person in a light blue shirt and light blue jeans sits on a rock, strumming a dark acoustic guitar. The individual's hands move rhythmically over the guitar’s strings and fretboard, which is held vertically. The background features a grassy hill under a clear blue sky. The camera maintains a static low-angle perspective.

The person is seated and playing the guitar; the hands are moving to strum and press the strings, which is the discrete object motion.

The background (sky and hill) is static with no significant ambient motion (no fire, water, wind).


RAW CAPTION: Got it, let's tackle this. First, the video starts with a person in a dark sleeveless shirt against a dark, blue-toned background with clouds. Then the background changes to a mountainous landscape with a sunset, the person is still there, maybe gesturing. Next, it's an ocean scene with a sunset, the person's hand movements. Then a scene with a woman in a black dress, maybe with a man in a suit, but the main subject is the person from before. Wait, the main subject is the same person throughout? Wait, the video transitions between different backdrops: first dark, then mountains, then ocean, then a different scene with a woman and man. But the main subject is the person in the dark shirt. Wait, in the initial frames, it's the same person. Let's check the sequence:

[0.0] - Person in dark sleeveless shirt, background dark blue with clouds.

[1.4] - Background changes to mountain range with sunset, person still there, maybe hand gesture.

[2.5] - Same person, same background, hand movement.

[3.6] - Background becomes ocean at sunset, person's hand gesture.

[4.7] - Background changes to a scene with a woman in black dress and a man in suit, person's hand movement.

So the main subject is the person in dark sleeveless shirt. Chronological order: starts with dark background, then mountain sunset, then ocean sunset, then a scene with a woman and man. The person's actions: in each frame, their hand is moving (gesturing). Let's note the appearance: dark sleeveless shirt, short hair. Number: one person. Spatial relationships: the person is in front of the changing backdrops. Backgrounds are changing, but minimal descriptions. Camera perspective: seems like static shots, maybe slight camera movement? Wait, the rules say "conclude with camera perspective and movement". The video is a series of clips where the background changes, so the camera might be static but the background shifts. Wait, the video transitions between backgrounds, so the person remains in the same position, but background changes. So for each frame, the person is centered, hand gestures. Then at the end, a new scene with a woman and man, but the person is still there? Wait, the last frame shows a woman and man, but the person in the dark shirt is still present? Maybe not. Wait, the user provided five frames. Let's list:

Frame 0: person in dark sleeveless shirt, dark blue background (clouds, maybe night).

Frame 1.4: person same, background mountains at sunset.

Frame 2.5: same person, mountain background, hand gesturing.

Frame 3.6: person same, ocean sunset background, hand gesture.

Frame 4.7: background changes to a scene with a woman in black dress and a man in dark suit, person is still there but maybe partially obscured? Wait, no, the person is in the foreground. Wait, the video's description says the person is the main subject through the transitions.

Wait, the task is to describe motion and behavior chronologically. So the person is in front of different backdrops, gesturing with their hand. The backdrops change: dark, mountains, ocean, then a scene with a woman and man. Let's structure the caption.

Start with the first scene: person in dark sleeveless shirt, short hair, standing against a dark blue backdrop with clouds. Then transitions to mountainous landscape at sunset, person continues to gesture with their right hand. Then to ocean at sunset, same person gestures. Then background changes to a scene with a woman in black dress and a man in dark suit, person remains, gesturing.

Wait, but the background changes are the key. Need to list the sequence of background changes and the person's actions.

Rules: focus on motion and behavior of main subjects. Main subject is the person. Describe their appearance (dark sleeveless shirt, short hair, 1 person). Then chronological order of their actions: in each frame, they are gesturing with their hand. Backgrounds change.

So step by step:

- Initially, a person with short hair wearing a dark sleeveless shirt stands against a dark blue background with cloud patterns.

- The background transitions to a mountainous landscape at sunset, where the person continues gesturing with their right hand.

- Next, the background shifts to an ocean at sunset, with the person maintaining hand gestures.

- Finally, the background changes to a scene featuring a woman in a black dress and a man in a dark suit, while the person continues gesturing.

Camera perspective: likely static, but the background transitions imply cut or slide. But the task says "conclude with camera perspective and movement". The description says "camera perspective and movement (e.g., top

A boy is making hand gestures and slight head movements, which are discrete object motions consistent with speaking or presenting.

The background changes abruptly from a stormy sky to an ocean sunset at frame 0.5 (likely a cut), and in the ocean scene the background appears static (waves are not moving significantly to dominate the scene). No dominant fluid or environmental motion observed.


RAW CAPTION: Got it, let's break this down. The video starts with hands wrapping bacon around scallops on a paper towel. Then they use a toothpick to secure it. Next, the scene shows the wrapped scallops on a tray. The hands place the bacon-wrapped scallops onto a baking sheet lined with parchment paper, arranging them in rows.

First, identify the main subjects: hands, scallops, bacon, toothpicks, baking tray. Chronological order: 1. Wrapping bacon around scallops with toothpicks. 2. Placing them on the tray.

Appearance: scallops are white, bacon is red/pink, toothpicks are wooden. Number: multiple scallops (maybe 4-5 visible). Spatial: hands are working on a paper towel, then moving to the tray.

Camera perspective: close-up shots, then a pan to show the tray.

Background: minimal, just kitchen counter, some items out of focus.

Now, write concisely: hands wrap bacon around scallops on a paper towel, secure with toothpicks; then place the wrapped scallops onto a baking tray lined with parchment paper, arranging them in rows. Camera is close-up, then pans to show the tray.

Check rules: focus on motion, chronological. Describe appearance (bacon, scallops), spatial (on towel, then on tray), camera movement. Exclude text, named characters.

Let me structure it:

A pair of hands wraps bacon around scallops on a paper towel, securing them with wooden toothpicks. The hands then transfer the wrapped scallops onto a baking tray lined with parchment paper, arranging them in rows. The camera remains close-up during wrapping and pans slightly to display the arranged scallops on the tray.

Wait, check for minimal background. The first scene has a paper towel, then tray. Background is kitchen counter, but minimal. So okay.

Check if concise: yes. Chronological: first wrapping, then placing on tray.

Now, confirm the output format: <caption_output>...<caption_output>

Let's write it.

<caption_output>A pair of hands wraps bacon around white scallops on a paper towel, securing each with a wooden toothpick. The hands then place the wrapped scallops onto a baking tray lined with parchment paper, arranging them in rows. The camera maintains a close-up perspective during the wrapping process and pans slightly to show the completed arrangement on the tray.<caption_output>

Hands actively manipulate discrete solid objects: wrapping bacon around scallops, inserting toothpicks, and arranging items on the baking sheet. The scallops, bacon, and toothpicks move due to explicit physical forces from the hands.

The background (countertop, baking sheet, and kitchen items) is stationary with no shifting or environmental fluid motion (fire, water, wind). Static elements like the baking sheet and countertop remain fixed throughout.


A man in a white shirt and gray pants dances closely with a woman in a gray top and black pants in a dance studio. They begin holding each other, then the man lifts the woman’s arm as they rotate clockwise while maintaining a close embrace, moving smoothly across the floor. The background shows mirrors reflecting the dancers and rows of chairs. The camera remains stationary, capturing their movement from a fixed angle in the studio.

Two dancers (a man and a woman) are moving in a coordinated dance routine, exhibiting locomotion and body rotation.

The background (walls and chairs) remains static with no shifting or fluid motion observed.


A person in a red shirt and dark shorts runs forward across a sandy field while swinging an object in their right hand. The individual moves from left to right, and the camera pans left to follow their motion, maintaining a wide perspective.

A child in a red shirt is running across the sandy field. The motion is due to locomotion (running) and is easily trackable with a bounding box.

Background elements (trees, playground structure, buildings) are stationary and do not exhibit fluid motion (fire, water, smoke) or wind-driven motion (swaying trees). The background is static with no uniform shifting.


An adult in a blue jacket and dark pants assists a baby with light hair, wearing a gray-striped shirt and blue jeans, in putting on a dark shoe while seated on the carpet. The baby holds the shoe, and the adult adjusts their position, leaning forward. The camera then shifts upward to a higher angle with a slight shake, capturing the interaction as the adult stands slightly, with a beige ottoman and white baby gate in the background.

Woman and child exhibit solid object motion through physical interactions (adjusting child's position, sitting down).

Static background elements (bench, baby gate, walls) show no uniform shifting; no fire, water, smoke, or wind motion present.


A pan filled with vibrant vegetables—red tomatoes, orange carrots, green broccoli, and yellow bell peppers—is vigorously stirred, causing the ingredients to move dynamically within the pan. The scene transitions to a wider kitchen shot where a person in a red shirt stands at the stove, tending to the pan. The camera shifts from a close-up of the vegetables to a medium view of the cook, maintaining focus on the cooking process while minimal background details are visible. The camera movement includes a transition from a top-down perspective of the pan to a side view of the kitchen.

Briefly describe what discrete, solid objects are moving.

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


A hand reaches toward a manual gear shift within a car, initially positioned near a denim-clad leg; the hand then interacts with the gear shift, manipulating its positions. The camera maintains a close-up view of the hand and gear shift, focusing on the interaction with minimal background visibility.

Hand (solid object) interacting with gear shift (solid object), exhibiting discrete motion due to physical manipulation (shifting gears).

No shifting background elements or fluid/environmental motion (fire, water, wind) observed; static background includes denim fabric (jeans) and car interior.


A pair of hands pours a yellow liquid from a small bowl into a white pan on a stovetop, then uses a whisk to stir the mixture. The hands pick up a green-labeled jar, pour its contents into the pan, and continue stirring. The camera maintains a close-up perspective focused on the pan and hands throughout.

Hands pouring liquid from a bowl into a pan while whisking; bowl is tilted and moved during pouring; whisk is actively stirred.

Background (stovetop burners and countertop) is stationary with no shifting elements; no fire, water, smoke, or wind present.


A woman with red hair and a striped shirt leans over a meat grinder while a bald man in a white apron operates the device, handling sausages on a green checkered table. She steps back, then a third person in white enters from the left, approaching the grinder. The scene occurs in a kitchen with light-colored cabinets; the camera remains static.

Two people are visible: one in an apron actively moving hands (likely preparing food) and another standing nearby. Their motions are discrete and attributable to physical actions (e.g., hand movements, body shifts).

The background (walls, cabinets, and floor) remains static with no uniform shifting or fluid motion; no fire, water, or smoke is visible.


A shirtless man in a gym bends forward, then turns and walks toward the right side of the frame while picking up a barbell. He lifts the barbell upward, holding it with both hands. Another person in dark clothing stands partially visible to the right. The camera remains handheld with a slight shake throughout.

A person is moving through the room via walking, turning, and adjusting their posture, exhibiting clear locomotion without external environmental forces driving motion.

Background elements (bathtub, pipes, walls) remain static with no uniform shifting or fluid motion (fire, water, smoke, wind) observed.


A person in a yellow shirt reaches toward a comic book rack, selecting a comic book and holding it up to display its cover. The hand grips the comic, revealing the barcode and spine, while the camera zooms in closely on the book against a backdrop of stacked comics. The camera perspective shifts from a wider view of the rack to a focused close-up of the comic and hand, with minimal background detail visible.

The person's hands actively manipulate solid comic book objects (arranging, positioning, and moving them), demonstrating explicit physical interactions.

The blue cloth and table background show no uniform shifting or fluid/environmental motion (no fire, water, or wind). Static background elements remain consistent.


A man in a green shirt and blue jeans leads a black horse with a rider wearing a blue helmet, red top, and yellow pants as they walk clockwise around a fenced enclosure. The camera follows closely, panning slightly to maintain focus on the pair.

Discrete solid objects include a horse (moving with the rider), a child (riding the horse), and an adult (walking alongside the horse). Their motion is due to physical locomotion (horse walking, child riding, adult walking).

Background elements (trees, fence, ground) show no significant uniform shifting or fluid/environmental motion (e.g., wind, water). Trees are static with no visible swaying or movement indicating wind.


Two individuals stand in front of a double door with arched glass panels; the taller person wears a red and black shirt with the number 3 and light shorts, while the shorter person wears a dark blue shirt with a star emblem and dark pants. The taller individual moves, causing the shorter person to exit the frame, then stands alone holding an object and gesturing with their hands. The camera remains static throughout.

Two people initially present; one exits the frame (red shirt), while the remaining person (dark shirt with star) exhibits subtle stance adjustments. Both movements are solid object locomotion.

Static background elements (doors, walls) show no shifting or environmental motion. No fire, water, smoke, or wind present.


A person with curly hair, wearing a red and blue Superman-themed shirt with a yellow "S" logo, sits on a dark couch. The individual raises their right hand to their face, then lowers it, followed by bringing a white object to their face. The camera remains static, capturing the person from the front against a simple background of the couch.

The person's hand and upper body exhibit discrete movements: covering face (0.2-1.3s), pointing (1.4-1.9s), and tissue use (4.5-5.0s). Motion is consistent with intentional human gestures.

Background (dark couch and wall) is stationary with no shifting or fluid motion. No fire, water, smoke, or wind observed.


RAW CAPTION: Okay, let's tackle this captioning task. The user provided a video clip with specific instructions. First, I need to remember the rules they gave. Let me read through them again to make sure I don't miss anything.

The main points are: focus on motion and behavior of main subjects in chronological order. Describe appearance and number (color, size, orientation). Mention spatial relationships if relevant. Conclude with camera perspective and movement. Keep background minimal unless essential. Exclude text recognition, named characters, or stylistic analysis.

Looking at the video description, there's a person in a black outfit doing an exercise. The video starts with them facing a wall with a mural of people. The text on the screen mentions movement up to 90 degrees and maintaining physiological cervical curves. The person is performing a squat-like movement, bending their knees and lowering their body. The camera is stationary, right? The background is a mural, but the user says to keep background descriptions minimal unless essential.

So the main subject is a single person. Their appearance: black shirt, black shorts, red shoes. They're facing away from the camera. The motion is squatting down, then maybe standing up. The chronology would be the person starting in a standing position, then lowering into a squat, and then maybe returning to standing. Wait, the video clips show them from 0 to 5 seconds. The first frame has them standing, then they squat down. So the sequence is: person stands, lowers body into squat, holds it, then maybe stands up? The exact actions need to be described in order.

Spatial relationships: the person is in front of a wall with a mural. The mural is behind them, so they're positioned facing the mural. But according to the rules, background should be minimal. So maybe just mention the wall is behind them but not describe the mural in detail.

Camera perspective: it's a fixed shot, no movement mentioned. So camera is stationary, looking at the person from the back.

Need to avoid text recognition. The text on the screen is part of the video but per rule f, exclude text. So don't mention the green text boxes.

Let me structure the caption. Start with the main subject: a person in black clothing, red shoes. They are standing facing a wall mural. Then, they lower into a squat position, bending knees to 90 degrees. The movement is described as squatting with the knees bent, maintaining posture. Then, perhaps they return to standing? Wait, the video shows them from 0 to 5 seconds, but the frames show the squatting action.

Wait, the first frame [0.0] shows them standing, then [1.4] they are in the middle of the movement, bending down. The movement is up to 90 degrees, so their knees are bending to 90 degrees. The text mentions "MOVIMENTO ATÉ 90°" which is the movement up to 90 degrees. So the person is squating down, knees bent to 90 degrees.

So the caption should describe the sequence: The person starts standing, then bends knees to squat down, maintaining posture. The camera is static, from behind.

Check the rules: no text, no named characters. So the description should focus on the motion: person in black, red shoes, facing a mural, squats down with knees to 90 degrees.

Wait, the exact motion: "MOVIMENTO ATÉ 90°" which is movement up to 90 degrees. So the person's knees are bent to 90 degrees. So when they squat, their knees are at 90 degrees.

So the sequence is: the person stands, then lowers into a squat, keeping the knees bent at 90 degrees. The movement is controlled.

Now, check the number of subjects: only one person.

Appearance: black shirt, black shorts, red sneakers.

Spatial: standing in front of a wall mural.

Camera: stationary, behind the person.

Need to mention the action in chronological order.

Putting it all together:

"A person in black athletic wear and red sneakers stands facing a wall mural, then lowers into a squat position, bending knees to 90 degrees while maintaining posture. The camera remains stationary behind the subject."

Wait, but the user says "briefly describe their appearance and number (color, size, orientation)." So maybe specify the orientation: facing away from camera.

The person is seen from the back, so orientation is facing the wall mural (which is behind them).

So revised: "A person wearing black shirt and shorts with red sneakers stands facing a wall mural, then squats by bending knees to 90 degrees while keeping back straight. The camera remains static behind the subject."

But check the rules: mention spatial relationships if relevant. The subject is in front of the mural. But the mural is

A child is dancing, exhibiting solid object motion through locomotion.

The background (mural on wall) is static with no fluid or environmental motion (fire, water, wind).
