RAW CAPTION: Got it, let's tackle this. First, the video is split into three panels. The left panel shows a person's legs in black and white socks with sneakers, probably doing a sport like basketball. The middle panel is a wider view of a gymnasium with players moving—maybe a basketball game? They're in red and white uniforms, I think. The right panel is an overhead shot of the gym with an American flag.

Looking at the sequence: the first frame (0.0s) has the left leg up, then in the next frames, the legs move, so maybe a jump shot or something. The middle panel shows players in action, maybe passing or shooting. The right panel stays with the flag.

Need to describe motion chronologically. Left panel: person’s legs in black socks, sneakers, moving from standing to jumping (since the foot goes up). Middle panel: multiple players (maybe 10-15) in red and white uniforms, moving on the court, some shooting, others moving around. Right panel: static, the flag is there, but no movement.

Spatial: left panel is close-up of legs, middle is wide gym, right is high angle of gym. Camera perspective: the three panels are side-by-side, so maybe a split-screen, but the caption needs to mention camera perspective. Wait, the instruction says "camera perspective and movement" but since it's three panels, maybe each panel has its own. But the rules say "conclude with camera perspective and movement"—so for the entire video, maybe the overall perspective? Wait, the video is split into three vertical panels. So the camera view is split-screen. But the output needs to be a single paragraph.

Wait, the user says "a concise, chronological paragraph describing the provided video." So the video is a sequence of frames, each frame showing three panels. So in each frame, the left panel is legs, middle is gym action, right is flag.

So chronologically, the video starts with left panel: legs in black socks, sneakers, then the foot moves upward (jumping or shooting). Middle panel: players in red/white uniforms move around the court; maybe a game with multiple players, some jumping, shooting. Right panel: static American flag.

Appearance: left panel—black and white striped socks, black sneakers, white floor. Middle panel—multiple players (maybe 10+), red and white uniforms, basketball court. Right panel—American flag on wall, gym ceiling.

Motion: left panel—the person's foot lifts and then extends upward (maybe a jump shot). Middle panel—players are moving dynamically; some shooting, others running, passing. Right panel—no movement, flag is still.

Spatial: left panel—close-up of lower body, middle—wide gym view, right—high angle of gym with flag.

Camera perspective: the video uses a split-screen format (three vertical panels), with the left being a low-angle close-up, middle a wide shot of the gym, and right an overhead view of the gym's interior.

Now, rules: focus on motion and behavior of main subjects (people/animals/objects) in chronological order.

So start with the left panel: a person's legs (black socks, white sneakers) rise from the floor. Then the middle panel: multiple players in red and white uniforms move actively across the gym floor; some jump, others dribble or shoot basketballs. The right panel: an American flag is visible on the wall, remaining stationary. The video is displayed in a triptych format, with the left panel in close-up, the middle in wide-angle, and the right in high-angle perspective, with no apparent camera movement except the sequential frames showing the action.

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

First, the left panel: a person's legs in black and white striped socks and black sneakers lift upward. Then the middle panel: several players in red and white uniforms engage in basketball action across the gym floor, with movements like jumping and shooting. The right panel: an American flag hangs on the gym wall, static. The video is a triptych, with the left view close-up, middle wide, right overhead.

Check rules: chronological order. So the sequence of events: the legs moving (left), then the gym action (middle), then the flag (right). But it's a split-screen, so all three panels are present in each frame. So the video shows three simultaneous views.

Wait, the video starts at <0.3s> with three panels. Each frame has the three panels. So the action in each panel progresses over time. Let's check the frames: the left panel at 0.0s shows the foot up, then 0.3s: foot still up? Wait, the first frame (0.0s) is a split

Discrete solid objects moving: people walking on scaffolding (horizontal movement) and a crane/lifting device (vertical movement) with visible locomotion and physical force application.

The background elements (walls, American flag, scaffolding structure) show no uniform shifting; no fire, water, smoke, or wind motion observed. Static background remains fixed relative to the scene.


A group of people dance in a wooden-floored room. A woman in a blue-and-white dress and white cardigan dances with a man in a white shirt and suspenders, swaying together as they move across the space; other dancers in dark suits and casual attire join the motion around them. The camera pans left, following the shifting positions of the dancers within the room while maintaining a focus on their coordinated movements.

Multiple discrete solid objects (people) are moving via locomotion (dancing), with clear bounding box tracking of their motion patterns.

Background elements (wooden floor, walls, stage structures) show no uniform shifting; no fire, water, smoke, or wind present to indicate ambient environmental motion.


A person wearing a dark shirt sits at a table, interacting with objects including a large white container with a blue cap and a green bag with an orange item. The individual moves their hands and head slightly while seated, with the table items positioned to their right. The camera remains static with a slight shake throughout.

A person is manipulating a bouquet of flowers with hand movements, causing discrete motion of the bouquet. The person's head and hands exhibit controlled locomotion due to manual actions.

The background wall and static objects (e.g., white container, table items) show no shifting or fluid motion. No fire, water, smoke, or wind effects are visible.


A hand holding a white marker with a black tip draws on a sketch of a tree and a figure, moving the marker to add details to the tree trunk and surrounding elements. The hand shifts position slightly while sketching, focusing on the tree’s branches and the figure’s form. To the left of the sketch, a dark gray map of the Americas is partially visible on lined paper. The camera maintains a static top-down view throughout.


RAW CAPTION: Got it, let's tackle this caption. First, I need to watch the video and note the main subjects. The video shows people and a goat. Let's check the chronological order.

Starting at frame 0: a group of people is near a fence, some standing, maybe a red vehicle or cart. There's a goat. Wait, the first frame shows people and a goat. Let's see the movement. As the video progresses, the goat moves, people adjust positions. Let's list the sequence.

Frame 0: Group of people (maybe 4-5) near a wooden fence, a red cart or vehicle with items, a goat standing. Background has grass, hills.

Frame 1-2: Camera moves closer, maybe panning left. People are near the fence, goat is in front of them? Wait, the video shows the goat moving towards the fence. Wait, in the frames, the goat is near the fence, people are around.

Wait, the main subjects: people (several, maybe 3-4 adults and kids), a goat (light-colored, maybe white or beige). The goat is moving towards the fence. People are interacting with the goat, maybe guiding it.

Chronological order: The goat is seen near the fence, then the goat moves towards the people, who are standing by the fence. The camera is panning left slightly as it moves towards the group.

Background: grassy field, fence, hills. But according to rule e, keep background minimal. So mention if essential, but maybe just "grassy field" as context.

Now, structure the caption:

First, main subjects: people (number, appearance), goat (color, action). Then their movement.

"Several people, including adults and children, stand near a wooden fence in a grassy field; a light-colored goat moves toward them, with a red cart and blue bucket visible nearby. As the camera pans left, the goat approaches the group while the people adjust their positions."

Wait, check number: the video has a group. Let's count. In the frames, there are about 4-5 people. Let's say "a group of people".

Also, rule b: mention appearance briefly. People are in casual clothes (shorts, t-shirts), goat is light-colored.

Spatial: goat is near the fence, moving towards people. People are in front of the fence?

Wait, looking at the frames: the goat is on the right side (from the camera's view) moving left towards the people. So the goat is to the right of the people initially, then moves left.

Wait, the video starts with the group on the left, goat on the right. Then the goat moves left, toward the people.

Let me check the frames:

Frame 0: Left side: people near fence. Right side: red cart, goat standing near the cart.

Frame 1: Camera moves, goat is closer to people.

Frame 2: Goat is more toward the group.

Frame 3: Goat is approaching the fence.

Frame 4: Goat is near the fence, people are next to it.

So the goat moves from the right side (near the cart) towards the group, which is on the left.

So movement: goat moves left towards the people.

People are standing near the fence, some looking at the goat.

Now, structure:

A group of people (adults and children in casual clothing) stand near a wooden fence in a grassy field; a light-colored goat moves from the right side of the frame toward the group, approaching the fence. As the camera pans left, the people adjust their positions while the goat continues its approach.

Check rules:

a) Motion: goat moves left, people adjust.

b) Appearance: people casual, goat light-colored, number: group of people (4-5), goat is one.

c) Spatial: goat moves from right to left, near fence.

d) Camera: pans left.

e) Background: grassy field minimal.

f) Exclude text, names.

Now, concise. Let's make it shorter.

"Several people, including adults and children, stand near a wooden fence in a grassy field; a light-colored goat moves leftward toward the group, approaching the fence. As the camera pans left, the goat continues its approach while the people shift positions."

Wait, but "several" is vague. Maybe "a group of people" (4-5) but rule b says "briefly describe appearance and number". Number: "a group (4-5)" but maybe "a few people".

Alternatively: "A few people in casual clothing stand near a wooden fence; a light-colored goat moves toward them from the right side of the frame. As the camera pans left, the goat approaches the group while the people adjust their positions."

Check the video frames:

The goat starts on the right

Discrete solid objects (people) exhibit minor movements (e.g., shifting positions, gestures) without dominant fluid or camera-induced motion.

The background (fence, hills, grass) shows no uniform shifting or fluid motion (fire, water, smoke, wind); static elements remain consistent across frames.


A coffee machine with two white cups on its metal tray is shown. A hand with a checkered sleeve enters the frame from the top, adjusts the right cup, and retracts. The machine remains stationary, with metallic components visible. The camera maintains a fixed, close-up perspective throughout.

A hand moves to stir liquid coffee in a cup. The hand and the coffee are discrete objects exhibiting localized motion due to physical interaction (stirring).

The background (espresso machine, counter, and stationary elements) remains static with no shifting or uniform motion. No ambient environmental motion (fire, water, smoke, or wind) is observed.


A person wearing a white cap and dark shirt plays a flute, their fingers moving over the instrument's keys as they hold it to their lips; the individual remains seated in front of a staircase with railings and shelves in the background. The camera maintains a static perspective throughout.

The person's hands and flute exhibit subtle, localized movements consistent with playing the instrument (finger motions on keys), representing discrete solid-object physics.

Static background elements (staircase, railings, room clutter) show no shifting or fluid motion; no fire, water, smoke, or wind detected.

RAW CAPTION: Got it, let's break this down. The video starts with two side-by-side shots of a person applying wallpaper. The person is wearing a light blue striped shirt. In the first frame, they're using a squeegee on the left side, then in the next frames, they move to the right side, smoothing the wallpaper. The text "Squeegee edges and trim." is there, but we need to ignore text recognition. Then the scene cuts to a black screen with decorative patterns and the company name, but the rules say to exclude text recognition and named characters. So focus on the actions.

First, the main subject is the person applying wallpaper. Chronological order: they start by using the squeegee on the left wall, then move to the right wall, smoothing the wallpaper. Describe their appearance: light blue striped shirt, male, maybe medium build. Spatial relationships: in front of the wall, which has a brick pattern. The video shows two panels initially, then transitions to a black screen with patterns.

Wait, the rules say "background descriptions minimal unless essential". The wallpaper is brick-patterned, which is part of the action (applying to the wall), so maybe mention the wall's appearance briefly? But not too much.

So structure: Start with the two panels, person using squeegee on left and right walls, then transition to black screen with decorative pattern. But need to focus on motion. The person moves from left to right, using squeegee to smooth the wallpaper on both sides. Then the video cuts to a black screen with a decorative pattern.

Wait, the video starts with split screen (two panels), then shows the person in both panels using squeegee, then the split screen continues as they apply the wallpaper, then cuts to black with text. But we need to describe the motion.

So: A man in a light blue striped shirt applies wallpaper to a brick-patterned wall, using a squeegee to smooth the edges on the left side, then moving to the right side of the wall to trim and smooth the edges, with the video split into two panels showing both sides of the action. The scene then transitions to a black screen with a decorative swirl pattern.

Wait, but the rules say "chronological paragraph". So first the split screen, then the action, then the transition.

Wait, the first frame: split screen (two panels), left and right. Then the person is in both panels, moving from left to right on each side? Or each panel is a different view? The text says "Squeegee edges and trim." so the action is using squeegee on edges and trim. So the man is working on both sides, using squeegee.

Then, after the action, the screen turns to a black background with decorative swirls.

So the caption should describe the sequence: The video opens with a split-screen view showing a man in a light blue striped shirt smoothing a brick-patterned wallpaper on a wall using a squeegee, first on the left side and then moving to the right side; the man adjusts his position, using the tool to edge and trim the wallpaper. The scene then transitions to a black screen with a decorative swirl pattern.

Wait, but "background descriptions minimal". The brick wallpaper is essential because it's what's being applied, so maybe "on a brick-patterned wall" is okay.

Check the rules:

a) Motion: man applies wallpaper, uses squeegee on left, then right; then transition.

b) Appearance: light blue striped shirt, man.

c) Spatial: in front of wall, split screen (left and right panels).

d) Camera: initial split screen, then cut to black screen.

e) Background minimal: brick wallpaper is the main context, so okay.

f) Exclude text: so ignore the text.

So draft:

A man in a light blue striped shirt applies a brick-patterned wallpaper to a wall, using a squeegee to smooth the edges and trim on both sides in a split-screen view; he moves from left to right, adjusting his position to ensure the wallpaper adheres properly, then the scene transitions to a black screen with a decorative swirl pattern.

Wait, need to be concise. Let's make it a paragraph:

The video shows a man in a light blue striped shirt smoothing a brick-patterned wallpaper on a wall using a squeegee, first on the left side then moving to the right side in a split-screen format; he adjusts his stance and applies pressure to edge and trim the wallpaper, followed by a transition to a black screen with a decorative swirl background.

Check for chronological: start with split screen, action on left, then right, then transition.

Yes. Let's make it concise.
</think>

<caption_output>A man in a light blue striped shirt applies a brick-patterned wallpaper to a wall, using a squeegee to smooth edges and trim in

Two people are moving their hands and tools to squeeze edges and trim the wall coverings. The motion is explicit human locomotion and physical actions.

The background (walls and room interior) is static and does not exhibit fluid or environmental motion. No fire, water, smoke, or wind is present.


A hand with a ring holds a light-colored, flat piece of bread over a gas stove’s blue flame, moving it to char the surface; the bread is then flipped, revealing blackened spots, with the camera maintaining a close-up view of the action.

A hand manipulates a flat, circular food item (likely bread or similar) over the gas flame. The object is rotated and positioned near the flame, with clear physical interaction (e.g., moving toward/away from heat source).

Background elements (stove surface, burner, and wall) remain static with no uniform shifting. The flame is present but burns steadily without dominant fluid motion; it is a minor background element rather than the primary motion.


The slot machine reels initially display various symbols including letters, numbers, and animal icons; the reels then spin rapidly, causing symbols to blur and shift positions, before stopping at new configurations. The camera remains stationary, capturing the reels from a frontal perspective with minimal background details visible.

The slot machine reels (three distinct reels) are spinning and then stopping, driven by the machine's physical mechanism.

The background (cabinet and surrounding elements) is static; no shifting backgrounds or fluid/environmental motion (fire, water, wind) observed.


A person wearing a red shirt and dark pants walks forward on a tightrope, gripping two ropes for balance, maintaining a steady posture as they move across the horizontal line against a pale, overcast sky. The camera remains stationary, capturing the subject from a medium distance with minimal background detail.

A person (discrete solid object) is walking on a tightrope, moving from left to right with small balance adjustments.

The background is a cloudy sky with slow cloud movement, which is not dominant. The tightrope poles are fixed and do not shift uniformly, indicating no camera motion. No significant fluid motion (fire, water, smoke) is present.


A baby in a light green onesie with yellow floral details sits in a colorful seat featuring lion and leaf patterns. The baby holds a white bottle in one hand and a pink ring toy in the other. The baby moves both hands, then a hand enters from the left side and touches the baby's face. The camera maintains a close-up, top-down perspective with minimal background detail.

The baby moves its arms and legs. A hand (from an adult) enters the frame and moves to touch the baby's face and body.

The background is a static colorful seat pattern with no shifting elements or fluid motion. No fire, water, smoke, or wind present.


A hand turns a brass door handle, opens the door to reveal green foliage outside, then pulls the door closed. The camera remains stationary in a close-up view.

A hand interacts with a doorknob, turning it to open a door. The hand and doorknob are discrete solid objects undergoing motion due to physical manipulation.

The video features a split-screen layout: top-left shows a person in a red shirt and white pants swinging a bat at a tee in an indoor batting cage, moving back after the swing; bottom-left displays another individual in a red shirt and white pants swinging a bat while a person in gray stands nearby, also moving after the swing; right side shows a person holding a wooden bat steadily. The camera maintains a static split-screen perspective throughout, with minimal background detail beyond the batting cage environment.

Batter swinging bat, pitcher throwing ball, and ball in mid-air motion due to physical forces (muscle-driven swings, collision with ball).

The baseball field background (grass, dirt, stands) is static with no fluid motion (fire, water, wind). No significant environmental shifts detected.


Several people dance in an outdoor plaza, with two main dancers in pink and black tops and jeans stepping and turning in a circle. They interact, raising hands while others in the background observe. The camera follows their movement with a slight shake, capturing the scene near green umbrellas and buildings.

Two central dancers (man in black shirt, woman in pink) move via coordinated locomotion (stepping, turning, arm gestures). Additional dancers in the background exhibit similar discrete motion patterns without environmental influence.

No significant shifting background elements or fluid/environmental motion (fire, water, smoke, wind). Background objects like tables, chairs, and canopy remain stationary with minor positional shifts from crowd movement, not fluid motion.


RAW CAPTION: Got it, let's tackle this captioning task. First, the video shows a yellow Caterpillar bulldozer (but we can't mention the brand name per rule f, so just describe as yellow bulldozer). The main subject is the bulldozer moving in a dusty, open area. Let's check the sequence: at the start, it's moving forward, kicking up dust. The driver is inside. Then it continues moving, maybe turning slightly.

Rules: focus on motion chronologically. Describe appearance: yellow, large, tracked (since it's a bulldozer). Number: one bulldozer. Spatial relationships: not much, just moving in open area. Background is minimal (dusty ground, maybe distant structures but keep it minimal). Camera perspective: looks like it's stationary, maybe panning slightly? Wait, in the frames, the bulldozer moves towards the camera then turns. Wait, the video shows the bulldozer approaching, then turning, so camera might be fixed. Let's check the frames: the camera seems to follow the movement a bit? Wait, the first frame has the bulldozer on the right, then it moves left, then towards the camera. So the camera is probably static, capturing the bulldozer's movement across the frame.

Step by step:

1. Initial frame: yellow bulldozer moving forward, kicking up dust, driver visible inside the cab. It's a large tracked vehicle (bulldozer) with a blade at the front (though the blade might be attached). The ground is dusty, so dust is visible.

2. As it moves, it turns slightly, so the direction changes. The bulldozer continues moving, dust trailing.

3. At some point, it's moving directly towards the camera, then maybe turns again, but the video is short.

Now, chronology: The bulldozer starts moving forward on a dusty terrain, kicking up dust. The operator is inside the cab. It advances, turns, and continues moving through the area.

Appearance: yellow, large tracked vehicle, single operator visible.

Spatial: moving across the frame, from right to left then towards camera? Wait, the first frame has it on the right, then in frame 2 it's moving left, then frame 3 it's facing towards camera. So the camera is fixed, and the bulldozer moves towards and past the camera.

Background: minimal, just open ground with some distant structures (but rule e says minimal unless essential, so maybe just "dusty terrain" and "open area").

Camera perspective: The camera is stationary, capturing the bulldozer's movement. There's no obvious panning or zoom, just static view as the bulldozer moves through the frame.

Now, structure the caption:

Start with the main subject's action in chronological order. Describe the bulldozer moving, kicking dust, operator inside. Then note movement direction.

" A yellow bulldozer moves forward across a dusty terrain, kicking up dust behind it. The operator is visible inside the cab as the vehicle advances, turns slightly, and continues moving toward the camera. The camera remains stationary, capturing the bulldozer's motion in a wide shot of the open area."

Wait, check rules: exclude text recognition (so no 'CAT'), mention appearance (yellow, size, orientation). The bulldozer is a large tracked vehicle (bulldozer), yellow. Operator visible. Motion: moving forward, turning, approaching camera. Background: minimal, open area. Camera: stationary, wide shot.

Let me rephrase concisely:

"A large yellow bulldozer advances on a dusty terrain, kicking up dust as it moves. The operator is visible inside the cab. The vehicle turns slightly and continues moving toward the camera, with the camera remaining stationary throughout the sequence."

Check for chronological order: first advancing, then turning, then moving toward camera. Yes. Spatial: turning, moving toward camera. Camera: stationary. Background minimal, just dusty terrain.

Yes, that should work. Let's make sure to not include any text like 'CAT', just describe as yellow bulldozer. Also, check if 'tracked' is necessary—since it's a bulldozer, tracked is part of its appearance. So "large yellow tracked bulldozer".

So revised:

"A large yellow tracked bulldozer moves forward across a dusty terrain, kicking up dust. The operator is visible inside the cab as the vehicle advances, turns slightly, and approaches the camera. The camera remains stationary, capturing the bulldozer’s motion in an open area."

That's concise, chronological, covers motion, appearance, spatial (turning, approaching), camera stationary. Background is minimal (open area). Checks all rules.
</think>

<caption_output>A large yellow tracked bulldozer moves forward across a dusty terrain, kicking up dust behind it. The operator is visible inside

The CAT bulldozer (solid, distinct object) moves forward, kicking up dust; the operator is visible inside the cabin.

Background elements (sky, distant structures) remain static with no uniform shifting. Dust is secondary to the bulldozer's motion and does not dominate the scene.


A group of approximately six people in white shirts and red pants perform a synchronized dance routine on a stage with a purple curtain backdrop. They raise their arms, step in unison, and move their bodies rhythmically while facing the audience seated in front of them. The camera maintains a slight shake while capturing the performance from an audience perspective.

A group of dancers (discrete solid objects) are moving in coordinated motions (arm movements, stepping, body motions) which are due to physical locomotion and intentional motion.

The background (pink curtain) is static and shows no shifting or fluid motion. There are no environmental elements like fire, water, or smoke. The curtain remains consistent across frames.


A shirtless man in dark swim trunks swims freestyle in a pool, initially near the edge where another person stands on the deck. He propels forward with arm strokes and kicks, moving along a lane marked by green and blue dividers. The camera follows his motion, panning slightly to maintain focus as he swims away from the starting point toward the far end of the pool. The background shows the pool’s tiled edge and minimal deck activity, while the camera remains steady with a slight tilt to track the swimmer’s path.

Two hands manipulate a small black object with a silver metallic component, twisting it between fingers. The object is held closely, with the hands positioned centrally in the frame, against a blurred light brown background. Camera maintains a close-up perspective with minimal movement.

Two hands are actively manipulating a small, dark object (likely a wire or tool), exhibiting controlled physical movement through gripping and twisting motions.

Background shows a static wooden surface with no shifting or fluid motion (fire, water, smoke, wind).


A hand holds a gold watch with a Roman numeral dial and diamond-studded bezel, rotating it to display the front face, then turns to reveal the bracelet links from a side angle before showing the engraved back; the camera stays close-up, following the watch's rotation against a dark background.

A hand is actively rotating and adjusting a wristwatch, displaying its front, side, and back faces through deliberate movements.

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


The video displays a 3x3 grid of human eyes, each transitioning between open and closed states over time. Initially, multiple eyes are open, then sequentially blink and close with varying timing across the grid. The eyes are arranged in rows and columns, maintaining a static spatial layout. The camera remains fixed, focusing solely on the eye movements without background elements.

Individual eyes in the 6x3 grid are moving independently (blinking, slight lateral shifts), representing solid, distinct objects with clear pixel-level motion.

No shifting background observed. The grid structure of eyes remains uniformly static with no fluid motion (fire, water, smoke) or environmental wind effects. Background skin tones and grid alignment are consistent across frames.


A person in a gray shirt shuffles a deck of blue-backed playing cards, moving the cards in a rapid, overlapping motion with their hands. The hands remain centered in the frame as the cards are fanned and mixed. A second figure with dark hair is partially visible behind the hands to the left. The camera maintains a close-up perspective, slightly shaking while focusing on the card-shuffling motion.

Hands manipulating a solid deck of cards through shuffling and fanning motions; discrete solid objects moving due to explicit physical manipulation.

No visible shifting backgrounds or fluid/environmental motion (fire, water, wind); background elements (shirt, table) remain static with no uniform displacement.


A person in a yellow T-shirt with a dark design and dark pants holds a red frisbee aloft, then throws it downward. The individual lowers their head, bends forward, and retrieves the frisbee. The background includes a bed with patterned bedding and a blue wall; the camera remains static throughout.

A person manipulates an orange umbrella (swinging, raising, and lowering), with visible arm movements and body shifts. The umbrella is a solid object moving due to explicit physical forces (the person's actions).

Background walls and door are stationary; no fire, water, smoke, or wind observed. Bed covers and furniture show no fluid motion.


RAW CAPTION: Okay, let's tackle this video captioning task. First, I need to understand what the user is asking for. They provided a video description with several frames, and I have to generate a concise chronological paragraph following specific rules.

The main points from the rules: focus on motion and behavior of main subjects in order, mention appearance and number, spatial relationships if relevant, conclude with camera perspective and movement, keep background minimal, exclude text or named characters.

Looking at the video frames:

0.0s: A hand holding a green toy train (Thomas the Tank Engine, but I shouldn't mention the name per rule f). The background has a wooden track and other toys on carpet.

1.4s: The hand moves the green train towards a wooden track with red and black pieces. There's a red toy car on the track.

2.5s: The hand places the green train on the track. The track is circular, wooden, with red and black sections. The green train has a face and wheels.

3.6s: The hand moves the green train along the track. The track is on carpet, and there are other toy cars around.

4.7s: The green train is moving along the track, possibly completing a loop. The hand is still involved, guiding it.

Wait, the user says to exclude named characters, so I shouldn't say Thomas. Instead, describe the green train as a toy with a face, green body, wheels. The track is wooden with red and black elements.

Need to list the actions in order: hand holding green train, moving it towards track, placing on track, moving along track. Mention the spatial relationships: track is on carpet, other toys nearby.

Check if background is essential. The carpet is the background, but maybe too minimal. Maybe just mention carpet as the surface.

Camera perspective: seems to be a top-down view, maybe slight shake because the video is handheld.

Wait, the video starts with a close-up of the hand and train. Then the camera follows the train's movement. The camera might be handheld, so some movement.

Rules say to describe camera perspective and movement at the end.

So the chronology: Hand holds green toy train, moves it towards wooden track with red/black segments, places it on track, guides it around the loop, then the train continues moving.

Need to mention colors: green train, red and black track elements, carpet background.

Spatial relationships: hand is moving the train towards the track, which is on the carpet. Other toys are on the carpet near the track.

Now, structure the paragraph:

- Start with the hand holding the green toy train (size, color, wheels).
- Move towards the wooden track (describe track parts: red and black).
- Place the train on track.
- Guide it along the track, possibly around a loop.
- Mention the camera is top-down, slightly shaky.

Check rules: exclude named characters (so no Thomas), describe appearance (green, face, wheels), motion in order.

Final caption should be concise, chronological, mention main subjects (hand and train), spatial relationships, camera perspective.

Possible draft:

A hand holds a small green toy train with a face and silver wheels, moving it toward a wooden circular track with red and black sections on a carpeted floor. The hand positions the train onto the track, guiding it around the loop while other toy vehicles remain stationary nearby. The camera maintains a close, top-down view with slight movement.

Wait, need to check if "other toy vehicles" is okay. The video mentions "other toys" but the description says "a red toy car on the track" in frame 1.4. So maybe mention "red and black toy vehicles" but rule f says exclude named characters. But the toys are just color-coded, so maybe "red and black toy vehicles".

Wait, the rules say to exclude named characters. So "red and black toy vehicles" is okay.

But the video shows the red toy car on the track, so perhaps "a red toy car on the track".

Wait, but the user says "briefly describe their appearance and number (color, size, orientation)".

So in frame 1.4: "a red toy car on the track".

In frame 2.5: "the hand places the green train on the track", which has the red toy car already there.

So maybe include "a red toy car on the track" as part of the background.

But rule e says background descriptions minimal unless essential. So perhaps mention "a red toy car on the track" but only if essential for motion.

Hmm, but the motion of the green train is the main subject, so the red car might be a static background element. Maybe don't mention it, but since the green train is placed on the track, which has other toys, perhaps it's relevant.

Alternatively, maybe just describe the track as

A green toy train (Thomas the Tank Engine) is manipulated by a hand, with a blue block and other small objects placed near it. The hand interacts with the train, causing it to move and rotate on the track.

The background (carpeted floor, toy train tracks) shows no shifting or environmental motion. Static elements are stable, indicating no ambient environmental phenomena (fire, water, smoke, wind) or significant background displacement.

RAW CAPTION: Okay, let's tackle this video captioning task. First, I need to understand what the user is asking for. They provided a video description with several frames, and I have to create a concise chronological paragraph following specific rules.

The main subject here is a person performing on a trapeze. The video starts with the person hanging upside down, then they swing upwards, flip, and eventually move towards the left. The background is dark, with some stage lights visible. The person is wearing a yellow outfit and is attached to a purple ribbon.

I need to focus on the motion in chronological order. Let's break down the frames:

- Frame 0: Person is hanging upside down, legs up, arms outstretched, on the purple ribbon.
- Frame 1: They start swinging up, maybe transitioning to a flip.
- Frame 2: Continuing the upward motion, body moving towards the left.
- Frame 3: Now facing downwards, legs bent, arms extended again.
- Frame 4: Moving further left, still on the ribbon.
- Frame 5: Person is now inverted, legs up, moving left.

Wait, the user provided 5 frames but the timestamps are from 0 to 5. Let me check the movement. The sequence shows the person swinging from upside down, moving up, then flipping, and moving leftward. The key points are the motion: starting hanging, swinging up and to the left, then flipping back.

Appearance: The person is wearing yellow, small in frame (since it's a close-up?), but the description says "small figure". The ribbon is purple, attached to the trapeze.

Spatial relationships: The person is in the center of the frame, moving left. The background has stage lights (blue and red), but the user says to keep background minimal. So mention the lights briefly.

Camera perspective: The camera is static, top-down view. Wait, the description says "top-down" but in the example output, they mentioned "static, top-down". Wait, looking at the frames: the person is hanging from a trapeze, so the camera is likely positioned below, looking up at the performer. But the user's example output said "top-down", but maybe it's a slight angle. Wait, the user says to describe the camera perspective and movement. The user's rule d says "Conclude with the camera perspective and movement (e.g., top-down, pan left, slight shake)."

Looking at the frames, the camera doesn't move; it's a fixed position. So "static" and "top-down" or "looking upward"? The video shows the person suspended above the frame, so camera is below, looking up. So "static, upward perspective".

Wait, the user's sample might be different. But the main thing is that the camera doesn't move; it's static. So "static camera perspective".

Now, putting it all together. The main subject is a single person in yellow, swinging on a purple trapeze ribbon. Starts hanging upside down, swings upward and to the left, flips, moves leftward. The background has stage lights but minimal.

Check the rules:

a) Motion in order: starts hanging, swings up, flips, moves left.

b) Appearance: yellow outfit, single person.

c) Spatial: moving left, in front of the lights (but background minimal).

d) Camera: static, upward view.

e) Background minimal: mention the stage lights briefly.

f) No text, characters, stylistic analysis.

Avoid any extra details. Let's structure the sentence:

A person in a yellow outfit swings on a purple trapeze ribbon, starting upside down, then flipping upward and moving leftward across the frame, with stage lights visible in the background; the camera remains static.

Wait, but need to be more precise. Let me check each frame again.

Frame 0: person hanging upside down, legs up, arms extended. Then in frame 1, they start moving up and to the left. Frame 2: moving higher, frame 3: now facing down, legs bent. Frame 4: moving left. Frame 5: inverted again, moving left.

Wait, the movement is: starts hanging upside down, swings up (to the left), then flips, and moves left. So the sequence is: inversion, upward swing, flip, then continuing left.

Wait, maybe better to say: The performer begins hanging upside down, swings upward and to the left, executes a flip, and continues moving leftward along the ribbon.

Yes. So the caption should describe the motion chronologically.

Also, the person's size: "small figure" since it's a distance shot. So "small figure in yellow".

Putting it all together:

A small figure in a yellow outfit swings on a purple trapeze ribbon, starting upside down, moving upward and leftward

A single trapeze artist (human) performing swinging and rotating motion due to gravity and tension in the trapeze rope. Motion is clearly controlled and trackable.

RAW CAPTION: Got it, let's break this down. The video starts with a group of people on a golf course. The main subject is a man in a navy shirt and khaki pants preparing to hit a golf ball. There are other people around: one in a blue shirt, another in gray and white. The golf bag is visible with clubs. The man is adjusting his stance, holding the club, then takes a swing. The camera moves closer to him as he swings. Need to describe chronologically. Start with the initial scene, then the man's actions (adjusting, swinging), others in background. Mention their appearance briefly: navy shirt, khaki pants; blue shirt, gray shirt, white pants. Spatial: others stand behind or to the side. Camera perspective: starts at a medium shot, then zooms in on the main subject. Background is grass, minimal. Let's structure it.

First, identify main subjects: 3-4 people. The main man is in navy shirt, khaki pants, preparing to hit. Others are standing around. The camera moves from wider shot to closer on the golfer. Motion: he bends over, adjusts grip, swings. The ball is on the ground. So the caption should be chronological: starts with the group, then the golfer's actions, camera movement. Keep it concise.

Check rules: focus on motion and behavior in order. Mention appearance (color, size, orientation). Spatial relationships: the others are around him. Conclude with camera perspective. Background minimal.

Draft: "A man in a navy polo shirt and khaki pants prepares to swing a golf club on a grassy course, standing with his feet apart and hands gripping the club. To his left, a person in a blue shirt and black pants observes, while another individual in a gray shirt and white pants stands nearby holding a club. A golf bag with clubs is visible behind the group. The man adjusts his stance, lowers the club, and executes a swing motion. The camera moves slightly closer to focus on the golfer’s action, capturing his movements from a medium angle before zooming in on the club and ball."

Wait, but need to be concise. Maybe shorter. Let's make it tighter.

"A golfer in a navy polo and khaki pants adjusts his stance and swings a club on a grassy course, with three other people—two in blue and gray shirts, one in white pants—standing nearby. The golf bag with clubs is positioned behind the group. The camera zooms in on the golfer’s motion, capturing the swing from a medium angle."

Wait, rule f says exclude text recognition (like PGA on shirt? No, because it's a shirt, but rule f is exclude named characters or text recognition. So if the shirt has "PGA", that's text, so don't mention. So the golfer's shirt is navy, no mention of logo. So the main subject: navy shirt, khaki pants. Others: blue shirt, gray shirt, white pants.

Let me rephrase. First, initial scene: multiple people on grass. Main man (navy, khaki) prepares. Camera movement: starts wide, then zooms in.

"Three people stand on a grassy course; a man in a navy shirt and khaki pants adjusts his golf stance, holding a club while two others in a blue shirt, gray shirt, and white pants observe. A golf bag with clubs sits behind them. The man bends, positions the club, and swings, with the camera moving closer to capture his action."

Check chronology: preparing (adjusting stance), then swinging. Mentioning the people in order. Keep it concise.

Let me see the output must be a paragraph. Let's structure:

The video begins with a group of golfers on a grassy course. A man in a navy polo shirt and khaki pants positions himself to hit a golf ball, adjusting his grip and stance while others stand nearby: one in a blue shirt, another in a gray shirt with white pants, and a third person partially visible. A golf bag filled with clubs is positioned behind them. As the man executes his swing, the camera gradually zooms in on his motion, focusing on the club and ball, with the background remaining minimal.

Wait, but the rules say keep background descriptions minimal. So maybe omit "golfers" and just say "people" or "group".

Another version: "A man in a navy shirt and khaki pants prepares to swing a golf club on a grassy field, standing with his feet apart. Two other individuals stand behind him: one in a blue shirt and black pants, another in a gray shirt and white pants. A golf bag with clubs rests to the left of the group. The man adjusts his stance, grips the club, and swings, while the camera slowly moves closer to focus on his action."

RAW CAPTION: Got it, let's break this down. The video shows a snowy landscape with people skiing. First, there's a person in red skiing down a slope. Then another person in white joins them. The camera moves slowly, panning right maybe, to follow their movement. The background has trees, but the main focus is on the skiers. Need to describe their motion chronologically: the first skier in red starts moving, then the second skier in white appears. Spatially, they're on the snow, with the first skier ahead then the second. Camera moves from left to right, maybe. Let's check the timestamps: the first frame shows both, then the red skier is moving forward, then the white one comes into view. Wait, the video starts with two people: one in red, one in white. Then the camera pans right, so the skiers move towards the right side of the frame. Wait, in frame 0, two skiers. Frame 1: red skier is moving. Frame 2: red is further, white is behind. Frame 3: white skier catches up? Wait, maybe the camera is panning right. So the main subjects are two skiers: first one in red, then white. Chronologically, they start at the top of the slope, ski down, with the camera following. Need to mention their appearance: red jacket, white jacket. Number: two people. Spatial: moving from left to right across the snowy field, with trees in the background. Camera movement: slow pan to the right. Background minimal. So the caption should be: Two skiers, one in red and one in white, move across a snowy slope from left to right. The red-jacketed skier leads, followed by the white-jacketed skier, both gliding down the snow-covered terrain with trees in the distant background. The camera steadily pans right, tracking their movement.

Wait, check rules. a) Motion and behavior chronologically. So first, the red skier is moving, then the white one. But in the first frame, both are present. Let's see the video: frame 0: two people (red and white). Frame 1: red skier is ahead, white is behind. Frame 2: red is moving further, white is still following. Frame 3: red is getting farther, white is moving. Frame 4: red and white are closer to the camera? Wait, the frames show the skiers moving towards the right as the camera pans. So the sequence is: skiers start on the left, move right. Camera pans right to follow them. So chronologically: two skiers, red and white, glide across the snowy field from left to right, with the red-jacketed skier leading and the white-jacketed skier following closely behind. The camera pans slowly to the right, keeping them in frame. Background has trees, but minimal. So the caption: Two skiers, one in a red jacket and one in white, glide from left to right across a snowy slope. The red-jacketed skier leads, followed closely by the white-jacketed skier, both moving downhill. The camera pans right, tracking their descent against a backdrop of snow-covered ground and distant trees.

Wait, check rules f: exclude text recognition, named characters, etc. So no names. Also, be concise. Let's make it concise. Maybe: Two people, one in red and one in white, ski across a snowy field from left to right. The red-skied individual leads, followed by the white-skied person, both gliding downhill. The camera pans right to follow their movement, with trees in the background.

Wait, the video shows the skiers moving forward, so downhill. So the caption should capture the motion: chronologically, they start at the top (left side of frame) and move towards the right (lower part of the slope). Camera moves right to follow.

Let me structure it: First, mention the subjects (two skiers), their colors (red and white), their action (skiing), direction (from left to right), sequence (red leads, then white follows), camera movement (pan right).

So: Two skiers, one in a red jacket and one in a white jacket, ski downhill from left to right across a snow-covered slope. The red-jacketed skier leads, followed by the white-jacketed skier. The camera pans slowly to the right, tracking their descent.

Check rules: a) motion in order: they start moving, then the white follows. b) appearance: red and white jackets. c) spatial: red leads, white follows. d) camera: pans right. e) background minimal (trees in background but not described much). f) no names. g) think internally.

A single person (likely skiing) and other distant figures are visible moving down a snow slope. These are discrete solid objects exhibiting locomotion-driven motion, trackable by bounding boxes.

The background features stationary trees and snow-covered ground with no visible fluid motion (fire, water, smoke) or significant wind-driven effects. Background elements remain fixed, indicating no dominant ambient environmental motion.


A person with green nail polish adjusts a metallic eyelash holder on their eye, then removes it. The individual, wearing purple lipstick and a green top, turns their head slightly, revealing more of their face and makeup. The camera maintains a close-up perspective with minimal movement, focusing on the facial actions against a dark background.

A person's hand and face are moving—hand approaches and then retracts from the camera, while the head shifts slightly during the sequence. These are discrete solid objects with intentional motion.

The background is predominantly dark and static; no visible fluid motion (fire, water, smoke) or wind-driven movement is present.


RAW CAPTION: Got it, let's break this down. The video shows a boy getting a haircut. First, the main subject is a child wearing a black barber cape, sitting in a chair. An adult, probably a barber, is cutting his hair. The barber's hands are visible, using scissors. The boy is seated, facing slightly to the right. The barber is standing behind him, working on the top of the boy's head. In the background, there are other people, but we can keep background minimal. Chronologically: the barber starts cutting, maybe moving scissors around. The boy is still, sitting. Camera perspective is steady, probably a fixed shot. Let's structure it.

Main subjects: a child (small, wearing black cape), barber (adult, hands visible). Action: barber cuts the child's hair with scissors. Spatial: barber behind the child, child seated. Background: indistinct people. Camera: stationary, eye-level? The video is vertical, so maybe camera is positioned to capture the scene from a standard angle.

Need to be concise. Let's draft:

A small child wearing a black barber cape sits in a chair while an adult barber, using scissors, trims the top of the child's hair. The barber’s hands move rhythmically as they cut, with the child remaining still. In the background, blurred figures are visible, but the focus stays on the haircut. The camera maintains a steady, close-up perspective throughout the sequence.

Wait, check rules. Chronological order: the action starts with the barber beginning to cut, then continues. Mention appearance: child's cape, barber's hands. Spatial: barber behind child. Background minimal. Camera: perspective—since it's a video, maybe "fixed camera" or "stationary."

Let me adjust:

A child in a black barber cape sits in a chair, while an adult barber uses scissors to trim the child’s hair. The barber’s hands move methodically through the hair, and the child remains stationary. The camera remains stationary, capturing the haircut from a fixed angle.

Wait, but the rules say "briefly describe their appearance and number (color, size, orientation)". The child is a boy, wearing black cape, small. Barber's hands visible. The action: barber cutting hair. So:

A small boy wearing a black barber cape sits in a chair as an adult barber, whose hands are visible, uses scissors to cut his hair. The barber’s hands move rhythmically across the boy’s head, with the boy remaining still. The camera maintains a steady, close-up view of the haircut process.

Check if background is minimal: "In the background, other people are faintly visible" but rule e says "background descriptions minimal unless essential". Since the main focus is the haircut, background can be mentioned briefly but keep it minimal. Maybe "a few blurred figures are visible in the background" but maybe omit if not essential. The original video shows some people in the background, but it's not essential for understanding motion. So maybe don't include.

Wait, the rules: "b) Briefly describe their appearance and number (color, size, orientation)". So for the main subjects: the boy (small, black cape), barber (hands visible). Motion: barber cutting hair, hands moving. Spatial: barber behind the child. Camera: stationary.

Let me check the example rules. The output should be a paragraph. Let's put it all together:

A small boy wearing a black barber cape sits in a chair while an adult barber trims his hair with scissors. The barber’s hands move rhythmically through the boy’s hair, with the child remaining still. The camera remains fixed, capturing the haircut from a steady, close-up perspective.

Wait, but the boy's orientation: sitting, facing slightly to the right (from the video). But maybe "sitting in a chair" is enough. Let's see.

Another version:

A small child, draped in a black barber cape, sits in a chair as an adult barber uses scissors to cut the child’s hair. The barber’s hands work methodically on the top of the child’s head, while the child remains seated. The camera maintains a stationary position throughout the sequence.

Yes, this covers the main points. Check rules:

a) Motion and behavior: barber cuts hair, hands move; child sits still. Chronological: starts with barber cutting, continues.

b) Appearance: child small, black cape; barber hands visible.

c) Spatial: barber behind child.

d) Camera: stationary.

e) Background minimal (omitted or implied).

f) No text, names.

g) Don't include reasoning.

So the caption should be concise. Let's write it as:

A small child wearing a black barber cape sits in a chair while an adult barber uses scissors to cut the child’s hair. The barber’s hands move rhythmically across the child’s head, with

Barber's hands moving to cut hair; child has minimal head movement.

Background (barbershop interior) is static; no ambient environmental motion (fire, water, smoke, wind) observed.


A crowd of people gathers outdoors; two women stand prominently in the foreground, one in a white crochet top wearing sunglasses, the other in a blue top with braided hair also wearing sunglasses, both facing forward as they move slightly within the group. The scene transitions to a woman wearing a silver tiara, adorned in a green and white gown, as someone pours water from a green bottle over her head from the left. The camera shifts from a medium shot of the crowd to a close-up of the woman with the tiara.

In the first scene, a crowd of people (including a woman in a white top) exhibits slight movement from talking/gesturing; in the second scene, a person in a costume holds and moves an object, showing discrete locomotion and gestural motion.

No shifting backgrounds or fluid/environmental motion. First scene has a crowd with static structures (e.g., distant people) that do not shift uniformly; second scene shows a person in a costume against a static architectural background with no fire, water, smoke, or wind.


A young child with short dark hair, wearing a light blue and white striped shirt and dark shorts, is seated in a stroller secured with a seatbelt. The child initially looks downward, then raises their head and turns slightly to the side while resting their hands on the stroller's sides. The camera maintains a top-down perspective, closely capturing the child's movements with minimal shifting.

The child (a solid object) is moving: leaning forward, then sitting up, and turning head. This motion is due to his own physical actions.

No significant shifting of background (sidewalk remains static) or fluid/environmental motion (no fire, water, wind).


A hand uses a green cloth to wipe a black leather car seat, then sprays the seat with a blue-capped bottle.
