A woman with black ponytail, wearing a white jacket over a yellow shirt, holds a large colorful children’s book. She adjusts the book’s position, turning its pages and shifting it to display different scenes, then looks toward the camera before returning her attention to the book. The scene takes place in front of a purple curtain with a yellow wall in the background; the camera remains stationary throughout.

A person in a white lab coat is holding and slightly maneuvering a book with cartoon illustrations; minimal motion.

Purple curtain and beige wall are static; no fluid/environmental motion (fire, water, wind) detected.


A person wearing a blue jacket, red pants, and yellow helmet moves across a snowy field while holding a kite control bar, advancing in a controlled manner. The camera transitions from a distant view to a closer frontal angle, capturing the individual’s steady motion against the snow-covered landscape.

A single person (skier) in a blue jacket and red pants is moving across the snow while holding ski poles. The motion is locomotion due to skiing.

The background consists of a static snowy landscape and clear sky with no fluid/environmental motion (fire, water, wind) or shifting background indicating camera motion. The snow and sky are stable.


A man in a brown suit walks toward green ATMs, stops in front of one, gestures with his hands toward the screen, and shifts position between the machines. The camera follows his movements, capturing close-ups of his interactions with the ATMs. The background includes a hallway with additional ATM units.

The man (Don Dahler) is the primary discrete object, exhibiting deliberate hand gestures and body movements while interacting with ATM screens.

Static background elements (walls, floor) show no uniform shifting or environmental motion; no fire, water, or smoke present.


Three individuals interact on a concrete parking area: a person in dark clothing with a visible number 9 on their back, a person in white, and a third individual. A person in a blue shirt stands motionless on the grass adjacent to the parking area, arms extended. The group on concrete shifts positions, with the person in white moving closer to the individual in dark clothing. The person in blue remains stationary throughout. The camera maintains a static top-down perspective.

Two individuals are engaged in a physical altercation (pushing/shoving) and a third individual is walking away.

Background is static with no shifting and no fluid/environmental motion (fire, water, smoke, wind) observed.


RAW CAPTION: Got it, let's tackle this. First, the video shows a person in a gym doing a bench press. The main subject is a person lying on a bench, wearing black clothes—shorts and a shirt. They're lifting a barbell with weights. Let's check the chronological order: the person starts with the barbell at chest level, then pushes it up, and then lowers it back down. The background has gym equipment like other benches and weights, but we need to keep background minimal.

Appearance: person in black attire, barbell with black weights. Spatial relationships: the person is on the bench, barbell is in front of them. Camera perspective: the video starts with a view from above, maybe slightly angled, and there's a slight shake as it moves. Wait, the video clips show the person in action, so the camera is probably fixed but with some slight movement. Let's see the frames: the camera angle is from above the bench, maybe a side angle. Wait, the description says "top-down" but let's check. The initial frames show the person on the bench, so camera is likely above, maybe a bit to the side.

Need to mention the motion: the person lowers the barbell to chest level, then presses it up, then lowers it again. Wait, the video is a sequence of frames: in frame 0, the barbell is being lifted up (since the person is pushing it up), then in frame 1, it's higher, etc. Wait, no—the first frame shows the barbell at chest level, then as the person presses, the barbell moves up. Let's confirm: the person is performing a bench press, so the action is lowering the barbell to the chest, then pushing it up. Wait, no: bench press is typically lying down, barbell on chest, then lifting it up, then lowering back. So the motion is: start with barbell at chest, push up, then lower back down.

So chronological order: person in black shorts and shirt lies on bench, grips barbell with weights, lowers barbell to chest level, then presses it upward, then lowers it back. Wait, the frames show: in frame 0, barbell is at chest, then in frame 1, maybe the barbell is being pushed up? Wait, the first frame shows the barbell being lifted (so the person is in the upward phase), then subsequent frames show the barbell moving. Wait, the video is a short clip of the person doing a bench press, so the sequence is: the person is lying down, grips the barbell, lowers it to the chest (but no—wait, bench press is usually starting with the barbell above the chest, then lowering to chest, then pressing up. Wait, no: when lying on the bench, you start with the barbell held at chest level, then lower it to the chest (no, wait, standard bench press is: you press the barbell up from the chest, then lower it back. Wait, no: the person starts with the barbell above the chest, then lowers it to the chest, then pushes back up. Wait, but in the video frames, the first frame shows the person with the barbell at chest level, then in the next frames, they push it up (so the barbell moves away from the chest), then maybe lower it back. Let's check the video description.

Wait, the user provided 5 frames: [0.0] to [4.7] seconds. The first frame shows the person lying on the bench, barbell at chest, then as the video progresses, the barbell is lifted up. So the motion is: person is lying on bench, lifts the barbell upward from chest level, then maybe lowers it. Wait, but the user's example says "lowers the barbell to chest level, then presses it upward". Wait, no—bench press: the person starts with the barbell at chest level (or slightly above), then presses it up to arms extended, then lowers back to chest. But in the frames, maybe the person is pressing it up and then lowering. Let's parse the movement:

Frame 0: person on bench, barbell is at chest level (or starting to lift)

Frame 1: barbell is being pushed up (so moving away from chest)

Frame 2: barbell is higher up (closer to arms extended)

Frame 3: barbell is at the top of the press

Frame 4: barbell is being lowered back down

Wait, but the description says the video shows the person doing a bench press. So the sequence is: person lies on bench, grips barbell, lowers it to chest (no, that's not right). Wait, no: when you bench press, you start with

Barbell being lifted and lowered by the person performing a bench press; person's upper body movement is visible.

No shifting backgrounds observed; no fire, water, smoke, or wind present. Background elements (gym equipment, floor) are static.


A woman in a light blue top, orange leggings, and bright orange-pink sneakers performs an exercise on a pink mat outdoors, lying on her back with legs elevated onto a black exercise ball. Initially positioned in a wide shot with a house, pool, and patio furniture in the background, she adjusts her legs on the ball, shifting her body slightly as the camera zooms in to focus on her lower body and the ball's movement. The camera remains steady, capturing her controlled motion as the ball rolls slightly beneath her feet.

Briefly describe what discrete, solid objects are moving.

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


A bald person in a white shirt stands in front of an electronic dartboard with a blue and red scoring ring. They raise their right arm to throw a dart, release it toward the board, then turn away. A television screen displaying indistinct content remains static on the left side of the frame. The camera remains stationary throughout.

A person (discrete solid object) moves their arm to throw darts, exhibiting locomotion and projectile motion; the person's body position changes (preparing, throwing, stepping back).

Background elements (walls, TV, dartboard) remain static; no shifting backgrounds, fluid motion, or environmental forces (fire/water/smoke/wind) observed.


An elderly woman with short light hair and an elderly man in a black-and-white striped shirt sit at a table with a white birthday cake adorned with lit candles and pink flowers. A woman with dark hair enters from the right, leans over the table, and interacts with the couple; the elderly woman turns toward the man, who reacts with a broad smile as the woman gestures near the cake. The camera remains mostly stationary with slight movement, capturing the interaction from a frontal perspective.

Discrete solid objects (the elderly couple, the woman, and the cake) are moving: the elderly man blows out candles, the woman enters the scene and interacts, and the elderly woman leans in. The motion is due to explicit physical forces (breathing, talking, and body movement).

The background (shelf, glassware, flowers) is stationary. No significant fluid/environmental motion (like fire, water, wind) dominates; the candle flames are minor and not the primary motion.


RAW CAPTION: Got it, let's break down the video frames. First, there's a computer monitor showing "Eco-Friendly Features" with a keyboard. Then a man in a gray suit at a desk with a laptop, maybe typing or interacting. Next, a printer outputs a colorful map. Then three people in a room: one in blue holding a cup pointing, others facing him. Need to order chronologically.

Check each frame:

0.0s: Computer screen with "Eco-Friendly Features" text, keyboard visible, monitor in office.

0.8s: Man in gray suit at desk with laptop, white room.

2.2s: Printer outputting a colorful map (blue, green, red areas), paper coming out.

3.5s: Three people: man in blue, woman in white, another man. One holding cup pointing at another.

Now, describe motion/behavior in order.

Start with the computer display (static), then man at desk (maybe typing), then printer printing map (motion of paper coming out), then the three people interacting (one pointing).

Make sure to mention appearance: man in gray suit, blue shirt, etc. Spatial relationships: e.g., the man is at the desk, the printer is emitting paper, the three people are in a room with one pointing at the others.

Background: minimal, so just note the office setup briefly.

Camera perspective: each shot is different, but need to mention camera movement? The rules say "conclude with camera perspective and movement".

Wait, rules: "Conclude with the camera perspective and movement (e.g., top-down, pan left, slight shake)."

So for each frame, what's the camera doing? First frame: close-up of monitor, then man at desk (medium shot), printer close-up, group shot.

But the caption should be chronological paragraph. So:

Start with the computer screen showing text, then the man at the desk working on laptop, then the printer outputting a map, then the group of three people interacting.

Need to check if it's a sequence. The video starts with [0.0] showing the computer, then [0.8] man at desk, [2.2] printer, [3.5] three people. So order: 0.0 → 0.8 → 2.2 → 3.5.

Now, describe each step.

First frame: computer monitor displays text (but rule f says exclude text recognition, so don't mention "Eco-Friendly Features" text). Wait, rule f says "Exclude text recognition, named characters, or stylistic analysis." So can't mention the text on screen. So for first frame: computer monitor shows an interface (but don't specify the text), then keyboard. But the description should focus on motion. First frame is a static shot? Maybe the monitor is the main subject.

Wait, the first frame (0.0s) has a computer monitor with a display, keyboard. But since we can't mention text, describe the monitor as showing a screen with an interface (but maybe the content is not important). Then next frame: man in gray suit at desk with laptop, possibly typing (motion). Then printer outputting paper with colorful image (motion of paper coming out). Then three people in a room, one in blue holding a cup and pointing, others looking.

So chronological:

A computer monitor displays a screen with interface elements; a man in a gray suit sits at a desk, interacting with a laptop; a printer ejects a sheet of paper with a colorful map; three individuals in a room, one in a blue shirt holding a cup and pointing towards another person.

Now check appearance: man in gray suit, blue shirt, etc. Number: three people. Spatial: man at desk, printer next to him (maybe), group in a room.

Background: minimal, so maybe not necessary to describe except where essential.

Camera perspective: first shot is close-up of monitor (but maybe top-down?), then medium shot of man, close-up of printer, medium shot of group.

But the caption needs to conclude with camera perspective and movement. So "The camera transitions from a close-up of the monitor to a medium shot of the man, then a close-up of the printer, and finally a medium shot of the group."

But need to check if "camera perspective and movement" is at the end.

Now, structure the caption:

[Start with first frame action] → [next action] → ... → [last frame action], ending with camera details.

Make sure to avoid text, focus on motion.

Let's draft:

The video begins with a computer monitor displaying an interface, then cuts to a man in a gray suit seated at a desk working on a laptop. Next, a printer ejects a sheet of paper with a colorful geographic image. Finally, three people gather in a room,

Discrete objects: doctor's hands (typing), printer paper (moving out of the printer), and people in the kitchen (talking and gesturing).

Background elements (blinds, printer body, kitchen walls) are static in all scenes. No fluid or environmental motion (fire, water, smoke, wind) observed. Printer paper movement is mechanical and not ambient.


A man in a gray shirt sits at a table with a wine bottle and a filled glass; he lifts the glass, takes a sip, then the scene transitions to a white screen displaying a purple dot cluster logo.

A person is moving their hand to lift and drink from a wine glass, indicating discrete solid-object motion due to explicit physical action (locomotion of hand).

Background elements (wine bottles, shelves, framed pictures) show no uniform shifting or fluid motion (e.g., fire, water, wind). No dominant ambient environmental phenomena detected.


Two individuals sit at a dark table; one wears a black shirt, the other a green shirt with a white logo. The person in black raises their hand to their mouth, while the person in green gestures with their hands and then touches their head. The camera remains stationary, capturing the scene from a frontal perspective.

Two individuals (solid objects) exhibit discrete movements: left person raises hand to mouth and adjusts posture; right person gestures with a napkin, then rests head on hand. Motions are deliberate human actions without fluid environmental interference.

Plain curtain background shows no shifting or movement; no fire, water, smoke, or wind present. Background elements (curtain) remain static throughout the sequence.


A person in a white polo shirt with gray trim sits at a table, actively stringing beads onto a bracelet using their hands. They pick up beads from a red and white bowl filled with black beads, then move the bracelet along the table. The table is cluttered with colorful jewelry pieces, including red, blue, and turquoise bracelets, and glass display cases with assorted beads are visible in the background. The camera maintains a top-down perspective with slight movement, focusing on the hands and the jewelry-making process.

Person's hands are actively manipulating a small object (likely a bead or jewelry piece) over a bowl; the object is being turned and possibly coated.

Background elements (display cases, table items) are static with no shifting. No fluid/environmental motion (fire, water, wind) observed.


A person wearing a dark shirt holds a small wooden ukulele, strumming with their right hand while their left hand presses the fretboard in a repeating motion; the camera captures this close-up frontal view from a stationary position, with the person seated in a room featuring minimal background elements.

A person's hands move rhythmically to strum a ukulele, with the instrument and body relatively stable while the hands exhibit discrete, solid-object motion from physical strumming forces.

The background (dark wall and furniture) remains stationary without uniform shifting; no fire, water, smoke, or wind is visible, indicating no ambient environmental motion.


A person wearing a black jacket, beige pants, and white gloves kneels beside a shallow stream, holding a large metal pan with both hands. They move their right hand into the pan while keeping the left hand on the pan's edge, seemingly sifting or examining its contents. The stream flows over rocks, with trees and greenery visible in the background. The camera remains stationary, providing a top-down view of the scene.

The man's hands and the bowl he is handling exhibit motion due to physical interaction (e.g., stirring or moving the bowl), representing discrete solid objects in motion.

The background elements (rocks, trees) are stationary, indicating no camera motion. There is flowing water in the stream, which constitutes ambient environmental motion, but it is not dominant compared to the main subject's actions.


A large marching band in red and black uniforms with Santa hats marches in formation down a city street, playing brass and drum instruments. They advance forward in unison, with members shifting positions slightly as they progress. The camera pans left, tracking the band’s movement along the street.

Marching band members in red/black uniforms move in coordinated formations. Their locomotion is solid and distinct, with clear tracking of individual musicians carrying brass instruments and drums.

Static background elements (buildings, street signs, and pavement) remain fixed relative to each other. No fluid motion (fire, water, smoke) or wind-driven phenomena dominate the scene; the environment is stable.


Two individuals in dark clothing handle a large, curved photographic print emerging from a printer. The person on the left crouches, supporting the print's lower edge, while the person on the right stands, adjusting the print's surface with their hand. Both move slightly as the print is processed, maintaining alignment with the printer. The camera remains static, capturing the action at eye level with minimal background detail.

Two people are physically moving to adjust and hold a large printed image, demonstrating discrete solid-object locomotion.

Background elements (printer, walls, furniture) show no uniform shifting or fluid motion. No fire, water, or smoke visible.


A child in a yellow cap and pink outfit stands before a wire fence, holding a bottle as goats gather around. Another child in a green shirt approaches, then an adult hands the child a bottle. White and brown goats lean forward to drink from the bottle. The camera shifts slightly to capture the children and animals, maintaining a close perspective with minimal background details.

Discrete solid objects: children and goats. Children move to feed goats, and goats approach the children for food, showing locomotion due to physical interaction.

Static background elements (fence, ground, trees) show no uniform shifting; no fire, water, or smoke present.


In a gym, a shirtless muscular man in black shorts and a man in a gray shirt and dark pants interact; the gray-shirted man holds the shirtless man's arm as they move, with the shirtless man stepping forward and pivoting while the gray-shirted man adjusts his grip. Other individuals sit on red mats in the background. The camera follows their movements with slight shake.

Two primary subjects: a shirtless man (discrete object) and a man in gray shirt (discrete object) exhibit controlled physical interaction (e.g., stretching, massage). Their motion is discrete, directional, and driven by direct physical contact, with clear bounding box tracking.

No fire, water, smoke, or wind present. Background elements (ropes, walls, gym equipment) remain stationary and consistent across frames, with no uniform shifting indicating environmental fluid dynamics.


A person in dark pants and sneakers, rollerblading, approaches the camera from the top right along a patterned pavement, executes a jump, and exits the frame; the camera remains static with a top-down view, showing minimal background of grass and rocks.

A person rollerblading enters from the right, moves across the frame, and exits to the left, exhibiting clear locomotion with distinct bounding box tracking.

The paved surface and grassy background show no uniform shifting or fluid motion; no fire, water, smoke, or wind is present.


A person wearing black shoes and light-colored shorts stands on a green, holding a golf putter with a white ball positioned at the putter's head. The golf hole lies to the right of the person. The individual swings the putter, striking the ball which rolls toward the hole; the ball then enters the hole. The person bends down to retrieve the ball. The camera captures a close-up view of the lower body and green, with slight movement as the person shifts position.

The golf ball moves from the golfer's stance toward the hole due to a club strike, and the golfer (body and club) moves during the swing. Both are solid objects subject to physical forces.

The background (grass and hole) is static with no shifting or fluid motion. No fire, water, smoke, or wind effects observed.


A woman in a pink top and black bottoms begins by gripping a vertical pole with one leg extended upward, then rotates around the pole into a split position, transitions to standing upright, and walks away from the pole. The camera remains stationary throughout, capturing the motion against a brick wall and wooden floor.

The woman (discrete solid object) performs pole dance movements: she moves her legs in splits, wraps around the pole, shifts weight, and spins. Her motion is controlled locomotion with no environmental interference.

Brick wall and wooden floor are static with no shifting, wind, or fluid motion. Background elements remain fixed throughout the clip.


A person in dark clothing and light pants moves across a central platform with fire effects, stepping and turning while the camera remains stationary with slight shake. The individual runs toward the background near a fence with a red banner, maintaining spatial orientation relative to the platform and enclosure.

A person is moving actively across the stage—walking, turning, and gesturing—indicating locomotion due to physical forces.

The background elements (vertical bars, hanging cloth) show no uniform shifting; fog is present but not dominant fluid motion. No fire, water, or wind-driven effects dominate the scene.


A man in a white shirt sits on a bed with a wooden headboard and patterned bedspread, rubbing his face with both hands. Warm light from a lamp positioned to the left illuminates the scene. The camera remains in a close-up perspective with minimal movement.

The person is moving their hands and head, which are discrete solid objects.

No shifting backgrounds or fluid/environmental motion (e.g., fire, water, wind) observed. Background elements (bed, wall, lamp) are static.


RAW CAPTION: Okay, let's tackle this. The user wants a concise chronological paragraph describing the video based on the provided frames. They gave specific rules to follow.

First, I need to look at the video frames. The first frame shows a hand using a wrench on a metal tool with multiple bolts. The text "Tiger Wrench" is there, but according to rule f, I should exclude text recognition. So I'll focus on the action.

Next frame: same hand adjusting a wrench on the tool. Then the scene changes to a mechanical engine part with stripped bolts. The text "STRIPPED BOLTS!" appears, but again, I need to skip that. The hand uses a different tool (maybe the Tiger Wrench) on the stripped bolts.

So the main subjects are the hand, the wrench, the metal tool, and the engine part. The action starts with the hand manipulating the wrench on the tool, then shifts to using the wrench on the engine's stripped bolts. The wrench is likely the Tiger Wrench, but since we can't mention text, just describe it as a tool.

Chronological order: first, hand using wrench on metal tool with bolts, then moving to engine part with stripped bolts, applying the wrench there. The background has some tools and boxes, but keep it minimal. Camera perspective: close-up shots, maybe top-down or close-up angles.

Check the rules: focus on motion, appearance (color, size), spatial relationships (e.g., hand is over the tool). Avoid background unless essential. Conclude with camera perspective.

So the caption should be: A hand adjusts a silver wrench on a vertical metal tool with multiple bolts, then shifts to a green engine component with stripped bolts, using the wrench to grip the damaged bolts. Camera maintains close-up focus on the actions with slight shifts between tools.

Wait, the first frame shows a hand on the metal tool. Second frame same, maybe moving the wrench. Third frame shows engine with stripped bolts, then the hand using the wrench there.

Make sure not to mention the text. So the main points: hand using wrench on metal tool (maybe the Tiger Wrench is the tool, but we don't name it), then on engine with stripped bolts. Describe the movement from one to the other.

Also, the hand's motion: manipulating the wrench on the tool, then applying it to the engine part. The wrench is likely metallic, maybe shiny. The engine part is green with metal bolts.

Check if spatial relationships are needed. The hand is on the tool, then on the engine. So "the hand moves from the vertical metal tool to the green engine component."

Finalize: Hand adjusts a silver wrench on a vertical metal tool with bolts, then applies the wrench to a green engine component featuring stripped bolts, gripping the damaged fasteners. Camera maintains close-up perspective, shifting focus between tools with minimal movement.

Wait, the user says to exclude text recognition, so no mention of "Tiger Wrench" or "STRIPPED BOLTS!" But the description should include the action of dealing with stripped bolts, since the video shows that. But the rules say exclude text recognition, so if the video shows "STRIPPED BOLTS!" on screen, but we can't mention it. But the action in the video is about stripping bolts. So maybe it's okay to mention that the bolts are stripped as part of the action, since it's part of the video's content, not the text on screen. Wait, the rules say "Exclude text recognition, named characters, or stylistic analysis." So even if the text is on screen, we can't refer to it. However, the fact that the bolts are stripped is shown visually, so we can describe the stripped bolts as part of the scene.

Wait, in the third frame: "STRIPPED BOLTS!" is text, but the video shows the actual bolts. So the caption should describe the bolts as stripped, even if the text is there. Because the text is part of the video's content but we can't reference it. Wait, the user's instruction says "Exclude text recognition", meaning if the text is on screen, we don't mention it. So if the video shows a scene with stripped bolts, but the text "STRIPPED BOLTS!" is on screen, then in the caption, we shouldn't reference that text. However, the visual shows the stripped bolts, so we can describe them as stripped. Because the text is not part of the content, but the visual is. The user's instruction says "Exclude text recognition", so the text itself shouldn't be mentioned, but the actual bolts being stripped (as seen in the video) can be mentioned.

Therefore, in the caption, we can say the engine component has stripped bolts, as that's a visual element. So the caption should describe the action of the hand using the wrench on stripped

Hand (discrete object) moves wrench (discrete object) to interact with stripped bolts on metal plate and green toolbox. Motion is controlled mechanical action due to physical force application.

Background is static with no shifting elements (wooden structure and green toolbox remain fixed). No ambient environmental motion (fire, water, smoke, wind) observed.


A person wearing a dark shirt, black pants, and beige boots walks toward a pile of bricks, bends down to pick up one brick, then stands upright holding it. The individual is positioned near white cinder blocks and scattered bricks on the concrete floor. The camera remains stationary throughout.

A person (wearing boots and blue shirt) is moving through the frame, walking, bending, and manipulating objects. The wooden frame on the floor is stationary.

No shifting backgrounds or fluid/environmental motion (e.g., fire, water, wind). Background elements (white brick walls, fireplace, wooden planks) remain stationary relative to each other.


A man wearing a blue striped shirt and jeans sits on a blue couch, holding a black clarinet to his mouth and playing; the camera starts with a static shot, then tilts upward and shifts slightly, maintaining focus on the man and instrument.

A man is playing a clarinet, with discrete movements of his hands on the instrument, his head, and body swaying due to playing.

The background (wall, bookshelf, furniture) is static with no uniform shifting. No fluid or environmental motion (fire, water, wind) is present.


A person wearing a dark t-shirt, dark pants, and pink footwear moves quickly from the left side of the frame toward the camera, then jumps and continues moving across the room, passing in front of a bed with colorful blankets and a shelving unit filled with storage boxes. The camera remains stationary throughout the sequence.

A person in athletic wear performs jumping and stepping movements. Solid, distinct object moving due to locomotion (jumping, leg lifts) with clear bounding box tracking.

Background elements (bed, shelves, walls) are static and unchanging. No fire, water, smoke, or wind-driven motion observed. Background shows no uniform shifting.


RAW CAPTION: Got it, let's break down the video. First, the scene is in a kitchen with wooden cabinets. A person in a blue Oklahoma City shirt is at the sink. They're washing something—maybe a dish or utensil. Then they switch to a black hoodie with "Oklahoma City" on it. They hold a yellow sponge, wash an item, and then pick up a white container. The camera stays fixed, no movement, just showing the person's actions at the sink. Background is minimal, just cabinets and a coffee maker. Need to keep it chronological: start with blue shirt, then change to black hoodie, actions at sink. Mention the items they're handling. Make sure to follow the rules: no text recognition, focus on motion, appearance, spatial. Let's draft.

First person in blue "Oklahoma City" shirt, washing with hands under faucet. Then they switch to black hoodie, hold yellow sponge, wash something, then pick up white container. Camera is stationary, fixed on the sink area. Background has cabinets but not too detailed. Need to be concise. Let's check the rules again. a) motion and behavior in order. b) appearance (colors, size). c) spatial: sink, cabinets. d) camera: stationary. e) background minimal. f) exclude text (so don't mention "Oklahoma City" as text, but appearance is the shirt color). Wait, the rules say "exclude text recognition", so we can't mention the text on the shirt, but the problem says "describe their appearance and number (color, size, orientation)". So the shirt color is blue, hoodie black. The text is on the shirt but since we can't recognize text, maybe just say "blue shirt" and "black hoodie" without the text. Wait, the example in the video: the first person is in a blue shirt with "Oklahoma City" but the rule says exclude text recognition. So we should just describe the shirt as blue, hoodie as black, not mention the text. So the caption should say "a person in a blue shirt" then "a person in a black hoodie". But the video shows them changing shirts? Wait, looking at the frames: frame 0: blue shirt. Frame 1: blue shirt. Frame 2: blue shirt. Frame 3: blue shirt. Frame 4: black hoodie. Wait, maybe it's the same person changing clothes? Let's check the video. The first part: person in blue shirt washing. Then they change to black hoodie, holding a yellow sponge, washing. So two different outfits, but same person? Or different people? The video is short: frames 0-4. So two people: first blue shirt, then black hoodie. Wait, the video shows the same person? Let's see the description: the person changes from blue to black. So it's the same person. So chronological: the person starts in a blue shirt at the sink, washing an item. Then they put on a black hoodie, hold a yellow sponge, wash another item, and handle a white container. Camera is stationary, fixed on the kitchen sink area. Background: wooden cabinets and a coffee maker on the counter. But background minimal, so just mention the sink and cabinets. Let's structure:

A person in a blue shirt washes an object under a faucet at a kitchen sink. They then change into a black hoodie, using a yellow sponge to scrub a dish, and pick up a white container from the sink. The camera remains stationary, focused on the sink area with wooden cabinets in the background.

Wait, check rules: exclude text recognition, so don't mention "Oklahoma City" on shirt. Just "blue shirt". Also, "number"—only one person. Spatial: in front of sink. Motion: washing, changing clothes, scrubbing, picking up. Let's make it concise. "A person in a blue shirt washes a dish under a kitchen sink faucet, then changes into a black hoodie, scrubs a plate with a yellow sponge, and handles a white container. The camera stays fixed on the sink area with wooden cabinets behind."

But need to follow exact rules. Let's check each rule.

a) Motion and behavior chronological: wash, change, scrub, handle.

b) Appearance: blue shirt, black hoodie, yellow sponge, white container.

c) Spatial: sink, cabinets.

d) Camera: stationary.

e) Background minimal: yes, cabinets are mentioned but kept minimal.

f) Exclude text: yes, no text.

g) Internal thinking: done.

Now, make it into a paragraph:

<caption_output>A person in a blue shirt washes an object at a kitchen sink, then changes into a black hoodie, uses a yellow sponge to scrub a dish, and picks up a white container. The camera remains stationary, focused on the sink

Two individuals interact with solid objects: one handles dishes (washing, drying) and a bowl, another uses a knife, bottle, and pours liquid. Their movements (reaching, gripping, pouring) are explicit physical actions involving discrete objects.

Background elements (wooden cabinets, wall decorations) show no uniform shifting. No fire, water flow, or wind-driven motion dominates the scene; water in the sink is controlled and not primary motion.


Two men stand on a stage; the left man holds a beige round hat and wears a brown blazer over a blue shirt, while the right man wears a dark suit with a striped tie. Both stand in front of a metal barrier with a band visible behind. The left man moves the hat and gestures, as the right man gestures with his hand. A woman in a white sleeveless dress runs past from left to right, followed by a man in a black suit holding a hat and a woman in a yellow sleeveless dress. The scene cuts to a news anchor sitting at a desk in a studio with computer monitors and office equipment in the background.

Discrete objects: two men (one holding a hat) and two women moving on stage by walking and stepping.

The stage background (metal fence) is static and does not shift. The news studio background is static. No environmental fluids (fire, water, smoke, wind) are present.


A female athlete in a blue top and blue shorts runs across a grassy field from left to right, holding a javelin toward the throwing zone. Spectators stand in the background, some near a blue and green landing mat. The camera pans right, following the athlete’s movement, then shifts focus to a seated individual in dark clothing to the right.

A runner in athletic attire (blue/red uniform) is sprinting along the track; other discrete objects include spectators and possibly a baton/relay stick in mid-air.

Static background elements (trees, field, distant spectators) show no uniform shifting. No fire, water, smoke, or wind-driven motion observed.


Hockey players in black jerseys with visible numbers skate across the ice rink, passing the puck and repositioning while a goalie remains in the net; the camera pans to follow the players' movement.

Ice hockey players (solid, distinct objects) are moving across the ice, actively skating and handling sticks with visible locomotion.

Static rink boards, banners, and seating areas show no shifting or fluid motion; no fire, water, smoke, or wind dominates the scene.


A girl in pink top and pants sits cross-legged on a patterned rug, interacting with a colorful book. A small gray dog approaches the book, then lies down in front of it, facing the girl. The girl remains seated, focused on the book. The camera maintains a static top-down perspective.

The girl (a person) is moving her hands and possibly adjusting her position while sitting, and the dog (an animal) is lying still but may have minimal movement. These motions are due to the objects' own actions.

The background (floor, rug, walls, furniture) is static and shows no shifting or fluid motion (e.g., no fire, water, smoke, wind).


RAW CAPTION: Okay, let's tackle this video captioning task. First, I need to understand the user's requirements. They want a concise, chronological paragraph that describes the video based on the provided frames. The rules are specific: 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 provided. The first frame shows a person in a blue shirt, white shorts, blue socks kicking a soccer ball on a green field. The background has a fence, trees, and a building. The next frames show the person continuing to run and kick the ball towards the goal. There's another person in yellow near the goal in frame 3.

Wait, the user specified to mention the main subjects' appearance and number. So the main subject is the person in blue. Then in frame 3, there's another person in yellow near the goal. The soccer ball is white. The ball is moving towards the goal, which is in the background. The background has a blue wall, trees, and a building. The camera seems to follow the action, probably a steady shot tracking the player's movement.

I need to structure the caption chronologically. Start with the initial action: the person kicks the ball. Then the movement towards the goal, with the ball rolling. The second person in yellow is near the goal. The camera is following the player's movement, maybe a follow shot. The background elements are minimal but should be mentioned if essential.

Wait, the rules say to keep background descriptions minimal unless essential. So maybe just mention the field and goal as part of the setting. The person in blue is running, kicking the ball towards the goal. The ball is white, moving towards the goal where another person in yellow is standing.

Check the frames again. Frame 0 shows the person kicking. Frame 1: same person running, ball rolling. Frame 2: same, ball moving. Frame 3: person near the goal, ball still moving. Frame 4: person continues to kick, ball in motion. Frame 5: approaching goal, ball in front. So the main subject is the player in blue, kicking the ball towards the goal. The other person is in yellow, standing near the goal.

So the caption should describe the player's actions in order: starts by kicking the ball, runs towards the goal, continues kicking, ball moves towards goal, another person in yellow near the goal.

Appearance: blue shirt, white shorts, blue socks. The ball is white. The other person is in yellow. The background has a green field, goal net, trees, buildings.

Camera perspective: following the player's movement, probably a steady tracking shot. No major camera movement mentioned, but the frames show the player moving from left to right, so camera might pan right slightly.

Need to be concise. Start with the player's initial kick, then the motion towards the goal, mention the ball's path, the other person near the goal. Then the camera movement.

Check the output format: it's a paragraph within <caption_output> tags. No markdown, just plain text.

Possible draft: A person in a blue shirt, white shorts, and blue socks runs on a green field, kicking a white soccer ball toward a goal. The ball rolls ahead as the person continues running, approaching the goal where another person in a yellow shirt stands near the net. The camera follows the player's movement with a steady pan to the right.

Wait, check the frames: frame 0-5 shows the person kicking, then the ball moving, then the player's foot making contact again? Wait, frame 0: person kicks ball. Frame 1: ball is rolling, person running. Frame 2: same. Frame 3: ball rolling towards goal, person continues. Frame 4: person runs past, ball still moving. Frame 5: ball near goal, person has moved away? Wait, the user's frames might show the player taking multiple steps. Wait, the frames are labeled as [0.0], [1.4], etc., but the video is a sequence. Maybe the player is jogging after the kick, then the ball rolls. The other person is in the background near the goal.

Wait, the key points are: player in blue shirt, white shorts, blue socks, kicking the soccer ball towards the goal. The ball is white. There's another person in yellow near the goal. Camera follows the player's motion.

Avoid mentioning background details unless essential. So maybe just "green field" and "goal" as the main setting. The person runs towards the goal, kicks the ball, the ball rolls toward the goal, where the yellow-clad individual is standing.

Camera movement: since the frames show the player moving from left to right, the camera is panning

A soccer player (in blue/white) and a soccer ball are visible. The player's foot collides with the ball, propelling it forward in a discrete, force-driven manner.

The background (blue wall, trees, goalpost) shows no uniform shifting or environmental motion (e.g., wind, water). No fire, smoke, or fluid dynamics are present.


A blue conveyor belt transports wooden blocks. Initially, a person in a white shirt handles blocks near the top of the conveyor, while a second individual in dark clothing stands nearby. The conveyor moves, carrying the blocks toward the camera, with the person in white occasionally adjusting the blocks. The camera pans slightly to follow the conveyor's motion, maintaining a close perspective on the belt and surrounding area.

Discrete objects include people (workers) interacting with boxes on a conveyor belt, with motion driven by manual handling and conveyor movement.

No shifting backgrounds or dominant fluid/environmental motion (fire, water, wind) observed; background elements like walls and fire extinguisher remain static relative to the scene.


A man wearing a dark t-shirt sits on a couch in a dimly lit room with a shelf holding small objects in the background. He puts on a cap, leans back, and picks up a cigarette, bringing it to his mouth and inhaling. The camera remains stationary throughout, capturing the sequence from a fixed frontal angle with minimal background detail.

A man is seated and moving his hands and head while eating a sandwich; his body and hand movements are discrete and solid.

No shifting background or fluid/environmental motion (fire, water, smoke, wind) detected; the room and shelves are static.


A person wearing blue shorts and yellow sneakers with red accents steps rhythmically on a green platform of a white step machine, alternating leg lifts in a steady motion. The machine rests on a concrete floor, with the individual’s lower body and the platform’s movement clearly visible. The camera remains stationary, capturing the action from a top-down perspective without movement.

The person's legs and feet are moving in a stepping motion on the treadmill belt, driven by their locomotion.

The background (concrete floor and wall) is static with no shifting; no fire, water, smoke, or wind present.


A person wearing a white shirt and blue jeans enters from the right, holding a cup, then moves toward a central table to place a red-backed ace of hearts card on its surface before stepping back. The table holds a white paper cup with a colorful design, a tall orange carrot, and a small orange carrot. The camera remains stationary, capturing the scene from a fixed perspective with minimal background detail.

A single person (wearing white shirt and blue jeans) is moving across the room; their locomotion is distinct and solid, involving walking from left to right and back to left while performing hand gestures.

No significant shifting background or fluid/environmental motion observed. The walls, door, sofa, and furniture remain stationary throughout the clip, indicating no ambient wind, fire, or water flow.


A man in a green shirt stands in a mall. A boy in a purple shirt and blue jeans enters, performs a backflip, and lands upright. A man in a gray shirt and khaki pants stands nearby as the boy walks away with others. The camera remains handheld with slight movement.

A person in a purple shirt falls backward due to a physical push (or loss of balance) and then stands up and walks away. Other people (in green and gray shirts) stand and observe, then the person in purple exits the frame.

The background (indoor mall) is static with no fluid motion (fire, water, wind) or significant shifting. No ambient environmental motion observed.


A person with red hair is shown in a close-up, smiling and shifting gaze direction while moving their head slightly, with hair moving gently; camera remains static throughout.

The woman's face and head exhibit subtle movements, including eye blinks, head tilts, and facial expressions, which are due to voluntary muscle movements (biological physical forces).

The background (trees) is static and out of focus, with no fluid motion (fire, water, smoke) or wind visible. Thus, ambient environmental motion is absent.


A baby wearing a light blue shirt holds a purple sippy cup with green and blue accents, moving it from the left side toward their mouth. The baby brings the cup to their mouth, drinks, then pulls it away, revealing their face. The camera remains in a close-up, slightly shaky perspective throughout, with a floral-patterned couch visible in the background.

The baby (a solid object) is moving the sippy cup to their mouth and then removing it, with the cup's motion being direct and due to the baby's hand movements.

The background (wall and furniture) is stationary and shows no shifting. There are no fluid or environmental motions (fire, water, wind).


Two children interact near a metal railing: a girl with a blonde ponytail wearing a blue hoodie over an orange top extends her right hand toward a boy in a purple shirt holding a yellow flower. The boy adjusts the flower as the girl lifts her hand upward, then lowers it. They stand in front of a white building with a red cloth on its wall. The camera remains steady with minimal movement, capturing their interaction from a medium angle.

Two solid objects (a woman in a blue jacket and a child in a purple shirt) exhibit motion due to human interaction: the woman moves her arm (holding a device) and the child responds with hand movements.

The static background elements (white wall, red banner, windows) show no uniform shifting or environmental motion (fire, water, smoke, wind). No ambient environmental phenomena are present.


RAW CAPTION: Got it, let's tackle this. First, the video starts with a person on a snowmobile in a snowy, forested area. They're wearing a black jacket and a helmet with red and white. Then the scene shifts to two people on snowmobiles moving across a snowy field. The second person is in a red jacket. They're riding towards the camera, maybe? Then the camera follows them as they come closer. The background has trees and snow-covered rocks. Need to focus on motion: starting with one person, then two approaching, camera perspective changing. Let's structure it chronologically.

First frame: One person on snowmobile in snow, trees around. Then next frames show two people on snowmobiles approaching, moving through the snow. The first person is black jacket, red/white helmet; second is red jacket. They're riding towards the camera, so the camera is probably stationary or moving with them. Wait, in the video, the transition is from a close-up of one person to two approaching. So chronological order: first scene with one person on snowmobile in snowy forest, then two people on snowmobiles moving towards the camera through a snowy area with trees and snow-covered rocks.

Need to mention number: first one person, then two. Appearance: one in black jacket, red/white helmet; other in red jacket. Motion: approaching the camera. Spatial: the second person is to the left or right? In the frames, when two are shown, the one in red is on the left, black on the right? Wait, looking at the video descriptions:

First frame: [0.0] one person on snowmobile, trees, snow.

Then [1.4] two snowmobiles, one with red jacket, one black. The person in red is approaching from behind? Wait, the caption says "two people on snowmobiles moving across a snowy field." So they're riding towards the camera, so the camera is in front of them. Then as they get closer, the perspective shifts. So the chronological order is:

1. A person in a black jacket and red-and-white helmet rides a snowmobile through a snowy forested area.

2. The scene transitions to two people riding snowmobiles toward the camera across a snowy field; one wears a red jacket, the other black, with snow-covered rocks and trees in the background.

3. The camera follows their approach, maintaining a low-angle perspective as they converge on the frame.

Check rules: focus on motion and behavior. Keep background minimal. Mention number, appearance, spatial. Conclude with camera perspective.

Let me draft:

A person in a black jacket and red-and-white helmet rides a snowmobile through a snowy forested area. The scene then shifts to two people on snowmobiles approaching the camera across a snowy field, with the rider in a red jacket on the left and the person in black on the right; snow-covered rocks and evergreen trees line the background. The camera maintains a low angle as the snowmobiles converge.

Wait, check if "left" is necessary. The description says in frame [2.5] "two people on snowmobiles moving across a snowy field" and the next frame shows them getting closer. Maybe the spatial relation is that one is to the left of the other.

Also, need to be concise. Let's make sure it's chronological. First frame: single rider. Then two riders approaching. Camera perspective: starts with a close-up of the first rider, then transitions to two riders moving toward the camera, camera following.

So:

A person in a black jacket and red-and-white helmet rides a snowmobile through a snowy forest. The scene transitions to two snowmobiles moving toward the camera across a snowy field, with one rider in a red jacket to the left and the other in black, surrounded by snow-covered rocks and trees. The camera tracks the approaching snowmobiles from a low angle as they draw nearer.

Wait, background descriptions minimal. So "surrounded by snow-covered rocks and trees" might be too much. Rule e says "keep background descriptions minimal unless essential for understanding motion." So maybe just "snow-covered terrain with trees."

Let me try again:

A person in a black jacket and red-and-white helmet rides a snowmobile through a snowy forested area. The scene shifts to two people on snowmobiles approaching the camera across a snowy field; one wears a red jacket, the other black, with snow-covered terrain and trees in the background. The camera follows their approach from a low angle, capturing them as they converge on the frame.

Check number: one person initially, then two. Appearance: black jacket, red/white helmet; red jacket. Motion: riding through forest, then two approaching. Spatial: the red jacket is to the left of the black. Background: snowy field, trees. Camera: low angle, tracking.

I think

Two individuals on snowmobiles move across the snow-covered terrain, demonstrating locomotion driven by the snowmobiles' engines.

Background elements (snow-covered trees, mountains) remain static and do not show uniform shifting; no fluid/environmental motion (fire, water, wind) dominates the scene.


A person with light brown hair in a bun and a dark green shirt with red text adjusts their hair, moving hands behind their head and turning their head to the left. They then continue moving their arms in front of their body. The scene is set in a pink-lit room with a bed visible to the left, holding a dark hat and clothes. The camera remains static with slight shake throughout.

A child is moving their arms and head (adjusting hair, then lying back).

Background elements (wall, poster, bed) are static with no significant fluid/environmental motion (e.g., fire, water, smoke, wind).


A person wearing a striped shirt runs into the frame from the left, extends their hand toward the camera, and then exits the frame. The camera remains stationary, focusing on the gravel path, bushes, and red gate in the background.

A person in a striped shirt and light pants walks towards the camera, extends their arms, and then passes close by, with their hand visible in the foreground.

The background elements (trees and red bench) are stationary and do not exhibit uniform shifting. There is minimal mist or dust, which is not dominant and does not qualify as environmental motion.


A person wearing dark pants and dark boots walks on a snow-covered ground, taking steady alternating steps forward. The camera maintains a low angle, closely following the subject’s lower body as they move, with distant buildings faintly visible in the background.

Two people (legs visible) are walking on the concrete surface. Their motion is discrete, solid, and driven by locomotion (footsteps and leg movements), with clear bounding box tracking possible.

The background (buildings and concrete ground) shows no shifting or uniform movement. No fire, water, smoke, or wind-driven environmental motion is present.


RAW CAPTION: Okay, let me tackle this. The user wants a concise chronological paragraph describing the video. First, I need to look at each frame provided.

The first frame is a black screen, so maybe it's a transition or intro. Then frame 2 shows hands holding a green Geocaching log sheet. Frame 3 is a person placing a stone on a wall. Frame 4 is someone lifting a rusty metal box. Frame 5 is a person in a dark jacket moving through a door with a radiator in the background.

Wait, the user said to focus on motion and behavior in chronological order. So start from the first action. The video starts with a black screen, then hands holding the log sheet. Then the person placing the stone, lifting the metal box, and finally moving through the door.

I need to describe each step. The first action is the hands holding the green log sheet. Then the person (gray hair, dark jacket) placing a stone on a wall. Next, the person in blue lifting a rusty box. Then the person in dark jacket moving through the door with radiator. Backgrounds are minimal except when relevant. Exclude text recognition, so don't mention "Official Geocaching" text.

Check for spatial relationships: hands are holding the sheet, person placing stone on wall, lifting box over head, moving through door. Camera perspectives: close-up on hands, then outdoor, then close-up on lifting box, then indoor shot.

Make sure to mention appearance briefly: hands in blue sleeves, person in dark jacket, blue jacket, gray hair. Also, the log sheet is green. The stone is on the wall. The metal box is rusty. The door has a radiator and clothes.

Wait, the rules say to exclude text recognition, so don't mention "Official Geocaching" but the green sheet is there. But the user said exclude text recognition, so maybe just say green sheet.

Need to be concise. Let me structure it:

- Hands in blue sleeves hold green log sheet. (but frame 1 is black screen, frame 2 is the log sheet)

Wait the video starts with [0.0] black screen, then [1.4] hands holding green sheet. So the first action is the black screen, then the hands. But the user says "focus on motion and behavior of main subjects". The black screen might not count as a motion. So maybe start from the first actual action.

Wait, the user provided the video frames with timestamps. So the first frame is [0.0] black, then [1.4] hands on green sheet. So the video starts with black screen, then shows hands. But the caption should be chronological. So the first part is the black screen, then the hands. But the rules say "focus on motion and behavior", so maybe the black screen is just a transition. The main actions are the hands holding the log, placing stone, lifting box, moving through door.

Wait the rules say "chronological paragraph describing the provided video". So start from the beginning of the video. The first frame is a black screen, then the next frames show the actions. The caption should mention all these in order.

But the user's example output probably skips the black screen as it's not a motion. Wait the user says "Focus primarily on the motion and behavior of main subjects". So the black screen is just a static image, no motion. So maybe start with the hands holding the log sheet.

Wait the problem statement says: "You are an expert video captioner. Your task is to generate a concise, chronological paragraph describing the provided video."

So the video starts with [0.0] black screen. Then [1.4] hands holding green sheet. So the caption should mention the sequence.

But the rules say to exclude text recognition, so the green sheet is just a green object. Let's see.

Let me outline:

1. The video opens with a black screen.
2. Then a close-up of hands (blue sleeves) holding a green log sheet.
3. Next, a person (gray hair, dark jacket) places a stone on a wall.
4. Then a person in blue lifts a rusty metal box.
5. Finally, a person in dark jacket moves through a door with a radiator visible.

Wait the frames are:

[0.0] black screen

[1.4] hands holding green sheet

[2.5] person placing stone on wall

[3.6] person lifting rusty box

[4.7] person in dark jacket moving through door

So in chronological order, the actions are:

- Hands hold green log sheet

- Person places stone on wall

- Person lifts rusty box

- Person moves through door

But the video starts with black screen, so the caption should mention that first. However, the rules say "focus primarily on motion and behavior". The black screen is

A person (discrete object) moves the geocache container, points at a stone wall, carries a heavy object on their head, and walks through a door. These motions are due to physical forces (locomotion, lifting, pointing).

No shifting backgrounds or fluid motion (fire, water, wind) observed. Background elements (stone walls, vegetation, indoor walls) remain static.


A person in front of a vehicle raises their arm and then moves their hand in a gesturing motion; the camera remains static from inside the car with slight shake.

No significant fluid motion (fire, water, smoke) or uniform environmental shifts observed. Store interior and digital displays remain static relative to the camera's perspective.


A person in a blue shirt and light cap sits at a table, playing a guitar. Another individual in a dark shirt enters from the right, moves across the frame in front of the guitarist, and exits to the left. The guitarist continues playing, occasionally adjusting their hands on the instrument. The camera remains mostly stationary with slight shake, capturing the scene from a medium distance.

The person in the blue shirt is actively playing a guitar, showing hand movement; another individual in the background is seated with minimal motion. These are discrete solid objects with intentional physical interactions.

The background features static rock formations and vegetation with no discernible shifting or fluid motion (e.g., no fire, water, smoke, or wind effects observed).


A man in a red shirt walks from the right side toward the left side of a split-screen view, approaching a dartboard, then releases a dart that lands on it. Another person stands in the background on the right side of the screen. The camera maintains a static split-screen perspective throughout.

The person in the red shirt is moving his arm and body (throwing darts), which is a clear physical motion of a solid object.

The background elements (room, furniture) are static and show no shifting. There are no signs of fire, water, smoke, or wind motion.


A man in a white shirt and dark shorts stands on a raised platform, gesturing toward a seated crowd behind a white wall with diamond patterns. The camera pans left, revealing a boy in a brown shirt and light blue shorts holding a bouquet, standing in the foreground with his back to the camera. The crowd, predominantly in white clothing, remains seated as the man shifts his position and moves his arms. The camera perspective is slightly shaky, capturing the scene from ground level with minimal background details beyond the crowd and platform.

The man on stage (wearing white shirt) is moving: bending, standing, and performing an action (likely pouring or building). This is a solid, distinct object moving due to locomotion.

The background (stage wall and ground) shows no uniform shifting. The crowd is stationary as a group (not a fluid motion). No fire, water, or smoke is dominant.

A yellow bucket enters the frame from the left and moves rightward, indicating discrete solid object motion; the tractor remains stationary.

Static background elements (trees, hills, sky) show no uniform shifting; no fire, water, or wind-driven environmental motion observed.


A person in a teal shirt and dark pants sits on a bed, leaning forward to place hands on the back of another person with dark hair lying face down on a striped bed. The standing person presses their hands against the back, then pulls back slightly as the lying person’s head shifts. The camera remains static, providing a top-down view with minimal background detail.

A standing person's hands interact with a lying person's back, exhibiting discrete physical contact motion (pressing, moving hands).

Static background elements (bed, striped bedding, red bag) show no uniform shifting or environmental motion (fire, water, smoke, wind).


A light-colored, fluffy cat lies on a wooden surface as a person's hand gently holds its paw while using scissors to trim the fur around the paw. The hand moves the scissors to cut the fur, with the cat remaining still. The camera maintains a close-up perspective, focusing on the paw and scissors, with slight movement to follow the trimming action.

The hands are actively combing the cat's fur, causing the fur to move. The cat remains mostly still while being groomed.

The background (wooden table and green bottle) is stationary with no fluid or environmental motion. No fire, water, smoke, or wind observed.


A person wearing a black shirt with white stripes and light blue pants sits on a couch, their hands moving toward a silver metallic container on a wooden table. They lift the container's lid to open it, then place the lid back down. The camera remains stationary, focused on the table and the person's hands.

Person's hands are interacting with a metallic container and a small object (which is placed on the table). The motion is due to the person's explicit manipulation.

No shifting background; no fluid/environmental motion (fire, water, wind) observed. Background appears static (wooden table and person's legs).


A pair of hands with brown sleeves positions a document over a white copier with its lid open. The hands carefully lower the document onto the copier's scanning glass, adjusting it to lie flat. The camera maintains a close-up view, focusing on the hands and the copier, with the blue wall visible in the background.

A person's hands (discrete solid objects) move the paper into the printer, demonstrating physical interaction with the paper.

Background elements (blue wall, office equipment) remain static with no shifting or fluid motion; no ambient environmental features observed.

A gloved hand picks up a yellow lemon from the ground and moves it away. The motion is a discrete physical interaction between the hand and the lemon.

Background (stone path and greenery) is static; no shifting uniform motion. No fire, water, smoke, or wind dominant.


A person in an orange shirt and blue jeans lies on the carpeted floor near a staircase, then pushes up with their arms to move into a kneeling position, followed by sitting upright. The staircase with brown carpet and a brown couch to the left remain visible in the background. The camera maintains a static, low-angle perspective throughout.

A person (boy) transitions from lying on the floor to sitting up, moving through distinct locomotion (pushing up with arms and legs).

Background elements (staircase, couch, walls) remain static throughout; no fire, water, smoke, or wind motion observed.

Background elements (walls, sofa, piano, framed pictures) remain stable with no uniform shifting; no fluid/environmental motion (fire, water, smoke, wind) detected.


RAW CAPTION: Got it, let's see. The video shows a person playing a harp. First, I need to describe the motion and behavior chronologically. The person is holding the harp, which is large with a red and wooden frame. They're wearing a white top and a pearl necklace. The harp is positioned against a white brick wall, and there's some greenery on the left. The person's hands are moving to pluck the strings. Then, the camera might move slightly, maybe panning a bit to show more of the background. Wait, the rules say to focus on motion and behavior in order. Let's start: the person is seated, holding the harp, plucking strings. The harp's color is red and wood. The person's clothing: white shirt, pearl necklace. Background has white brick wall and some plants. Then, maybe the camera moves a bit. Let's check the timestamps. The first few frames are close up, then maybe the camera pans to show more of the room. The person continues playing, hands moving on the strings. So chronological: person plays harp, hands plucking strings, camera shifts to reveal more background (like the wall and maybe a chair). Need to mention spatial relationships: harp is held by the person, strings are plucked. Background elements are minimal but essential. Wait, rule e says minimal background unless essential. So maybe just mention the white brick wall and some greenery on the left. Let's structure:

A person in a white shirt and pearl necklace plays a large red and wooden harp, plucking strings with their hands. The harp is positioned against a white brick wall with greenery visible to the left. The person adjusts their grip on the harp as they continue playing, and the camera slightly pans to reveal more of the room's background, including a chair and additional wall features.

Wait, need to be concise. Let's make it shorter. Focus on motion: "A person in a white shirt and pearl necklace plays a large red and wooden harp, plucking strings with their hands while seated. The harp is positioned against a white brick wall with greenery visible to the left. As the person continues playing, the camera slightly pans left to reveal more of the background, including a chair and wall fixtures."

Wait, check the output format. Need to be a paragraph. Let's make sure to include appearance, motion, spatial, camera. Let's draft:

A person wearing a white shirt and pearl necklace is seated, playing a large harp with a red and wooden frame, plucking strings with their hands. The harp is held against a white brick wall, with greenery visible to the left. The person's hands move rhythmically along the strings, and the camera slightly pans left to show additional background elements, including a chair and wall decorations.

Wait, the video starts with the person playing, then in frame 4-5, the camera moves. So the sequence is: initial shots of person playing, then camera pans. Let's make sure it's chronological. So the person is playing, then the camera moves. So the caption should mention that the camera pans. Let's check the rules: "conclude with camera perspective and movement". So maybe: "A person in a white shirt and pearl necklace plays a large red and wooden harp, plucking strings with both hands. The harp is positioned against a white brick wall with greenery to the left. The camera slightly pans left, revealing more of the background including a chair and wall fixtures as the person continues playing."

But need to be concise. Let's see:

A person in a white shirt and pearl necklace plays a large red and wooden harp, plucking strings with their hands while seated. The harp is against a white brick wall with greenery visible to the left. The camera slightly pans left, showing additional background elements such as a chair and wall decorations as the person continues to play.

Wait, "plucking strings with both hands"? The video shows one hand maybe? Let me check the frames. The first frame: left hand on the neck, right hand plucking. So maybe "plucking strings with one hand while holding the harp's neck with the other". But maybe simplify. The rules say "concise". Maybe "plucking strings with their hands". Let's check:

"A person wearing a white shirt and a pearl necklace plays a large red and wooden harp, using their hands to pluck the strings while seated. The harp is positioned against a white brick wall with greenery visible to the left. The camera slightly pans left, revealing a chair and additional wall elements in the background."

Is that good? Let's see. Mentioned appearance (white shirt, pearl necklace), harp's color (red and wooden), motion (playing, plucking), spatial (wall, greenery left),

The person is actively moving their hands to play the double bass, representing discrete, solid object motion due to physical interaction with the instrument.

The background includes a white wall and greenery; no uniform shifting of static elements (walls, ground) indicates no camera motion, and there are no fluid/environmental motions (fire, water, smoke, wind) present.


A man in a light suit and a woman in a vibrant dress with a large feather headdress dance energetically on a stage with red curtains. The woman spins and extends her legs as they move together, the man guiding her through turns and close embraces. A band with musicians sits to the left, partially visible. The camera follows the dancers' movements with a slight pan.

Dancers (couple) exhibit locomotion (spinning, stepping, lifting) and musicians remain stationary.

Red curtains and piano area remain static; no fluid/environmental motion (fire, water, smoke) observed.


A person in dark clothing rides a snowmobile along a snow-covered path toward the camera, slowing to a stop, then dismounts and stands on the snow. The camera remains stationary, capturing the sequence from a fixed position.

A person operating a snow blower moves toward the camera, then stops and transitions to walking away. The snow blower and person form discrete, solid objects exhibiting clear locomotion due to human action.

Static snowy landscape with trees and structures; no significant fluid motion (fire, water, smoke) or wind-driven phenomena observed. Background elements (trees, slope) remain uniformly still, indicating no dominant environmental motion.


A young child in a dark blue outfit with a blue inner shirt sits on the floor, hands resting on the ground, then bends forward to look downward. To the left, a doll with a blue bandage and colorful clothing lies on the floor; to the right, a green and white object is partially visible. The camera maintains a top-down perspective with slight shake throughout.

A baby in a blue outfit moves by bending forward and looking downward; the motion is due to intentional locomotion.

Background elements (toys, room structures) show no uniform shifting; no fire, water, smoke, or wind observed.


A person wearing a dark hoodie, khaki pants, and a colorful scarf bends over a red boat, then stands to open a black case, revealing small objects inside. Calm water is visible behind the boat, and the camera maintains a close perspective with slight shake.

A person interacts with a black case and small objects (e.g., coins or tokens), moving their hands to place items into the case and adjust its contents.

Background features calm water and a static horizon; no significant fluid motion (e.g., waves, smoke) dominates the scene. Water is stationary enough to be considered ambient but not dominant.


A person with curly red hair inside a car adjusts and puts on red over-ear headphones, then holds up a small object with their right hand. The background shows the car’s interior with a ceiling fan and window visible. The camera remains in a close-up position with slight movement.

The person is making hand gestures and moving their head. A water bottle is held and brought close to the camera.

The car interior background is static with no fluid motion (fire, water, smoke) or wind-driven motion. The background elements (ceiling, headlight) do not shift uniformly.


A person in a dark jacket holds a small white dog in a snowy forest. The scene shifts to another individual in a black coat interacting with two dogs (one white, one black and white) near snow-covered trees. Multiple sled dogs then pull a blue sled forward with a person wearing a red hat behind; the dogs run along a snow path as the sled moves, with the camera tracking the sled's motion through the forest.

People (multiple individuals wearing winter clothing) and dogs are moving: one person interacts with a dog, another person pushes a blue sled while dogs pull it, and additional people/dogs appear in subsequent frames. Motion is due to intentional locomotion (walking, pulling sleds) by solid objects.

Background trees and snow-covered ground remain static with no significant wind-induced motion (e.g., snow blowing or branches swaying). No fluid/environmental motion (fire, water, smoke) is visible.


A person in a white polo shirt uses their left hand to manipulate small brown fragments with tweezers while their right hand holds a thin tool to cut through a larger brown mass on a white surface, scattering brown crumbs around the area. The scene is observed from a static top-down camera angle, with a paintbrush positioned on the right side of the table.

The person's hands and a tool (tweezers) are manipulating small, broken chocolate pieces, exhibiting deliberate physical interactions (cutting, displacement) with discrete solid objects.

The person in the bathroom is the primary discrete object; their body and leg movements (lifting leg, adjusting position) are explicit physical actions driven by locomotion/shaving.

The bathroom background (tiles, bathtub, vase) shows no uniform shifting or fluid motion; no fire, water, smoke, or wind effects are present.


The video opens with a black screen before transitioning to a boy in a red shirt and striped shorts seated on a chair, playing a cello. He moves a bow across the strings while holding the cello between his legs. The background includes wooden cabinets and a fan. The camera remains stationary throughout.

The person (in red shirt and white shorts) and the cello are the discrete objects. The person's hands move with the bowing motion, and the body shifts slightly with the playing.

The background consists of static wooden doors and a mirrored wall with no shifting or fluid motion (fire, water, wind). No ambient environmental motion is present.


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 woman in a blue dress with silver embellishments standing on the left. A man in a gray shirt and jeans is bending over, holding a maroon saree. Another woman in a blue top and dark pants is near the man. The background has colorful fabrics and a poster.

Then, the second frame: The man stands up, holding the saree up high. The woman in blue steps back. The man in gray is now standing, holding the saree, and the woman in blue is moving away.

Third frame: The man turns, still holding the saree, the woman in blue is further back, and the woman in the blue top is near the man, maybe adjusting something.

Fourth frame: The man is bending again, maybe to put the saree down. The woman in blue top is now in front of him, and another person is in the background.

Fifth frame: The man is standing, the woman in blue is near the man's back, and the woman in blue top is moving away.

Wait, need to focus on main subjects. The main people: man in gray shirt (jeans, short sleeves), two women: one in blue dress with silver (left, standing), another in blue top and dark pants. Also, the maroon saree.

Chronological order:

- Initially, man is bending over, holding the maroon saree, with the woman in blue dress on left, and another woman in blue top behind.
- Then, man stands up, lifting the saree up (frame 2).
- Next, he turns, maybe adjusting the saree, while the woman in blue top moves around.
- Then, the man bends again, and the woman in blue top is near him.
- Finally, the man stands, with the woman in blue top moving away.

Need to describe their actions step by step.

Also, spatial relationships: woman in blue dress on left throughout. Woman in blue top is near the man, moving around. The man is handling the maroon saree, holding it, lifting, bending.

Camera perspective: looks like a fixed camera, no obvious movement (no pan, tilt, etc.), so maybe static. Background is a store with colorful fabrics, but minimal mention as per rules.

Exclude text recognition (like "SALE" sign, but the rule says exclude text, so don't mention). Don't name characters.

So the caption should be:

In a brightly lit store with colorful fabric displays, a man in a gray shirt and blue jeans bends forward while holding a maroon saree. A woman in a blue dress with silver embellishments stands to his left, and a second woman in a blue top and dark pants moves around him. The man then stands upright, lifting the saree high above his head before turning slightly to adjust it, while the second woman steps backward and shifts position. The camera remains static throughout, capturing the interactions from a fixed angle.

Wait, check rules: a) motion and behavior chronological. So start with first action.

First frame: man bending over (so action starts with bending), then stands up, lifts, turns, bends again, etc.

Let's structure:

The video begins with a man in a gray shirt and blue jeans bending over while holding a maroon saree. A woman in a blue dress with silver decorations stands to his left, and another woman in a blue top and dark pants is positioned near him. The man then stands, lifting the saree upward as the woman in blue steps backward. Next, the man turns his body, adjusting the saree with his hands, while the second woman moves closer to his side. Finally, the man bends forward again, and the second woman steps away, all while the camera maintains a steady perspective without movement.

Wait, check rule d: conclude with camera perspective. So "camera remains static" or "fixed angle".

Also, rule b: briefly describe appearance and number. The man: gray shirt, blue jeans. Women: blue dress (silver), blue top (dark pants). Two women.

Rule c: spatial relationships: woman in blue dress left of man, second woman near or behind man.

Let me draft:

In a store with colorful fabric displays, a man in a gray shirt and blue jeans bends forward holding a maroon saree. A woman in a blue dress with silver embellishments stands to his left, while a second woman in a blue top and dark pants stands near him. The man stands upright, lifting the saree high above his head as the second woman steps back. He then turns slightly, adjusting the saree, and the second woman moves closer to his side. The man bends forward again, and the second woman steps away. The camera

Discrete objects (humans) exhibit physical interactions: a person in blue moves across the frame, another in gray handles a cloth while interacting with a person in a red apron, and others engage in gestures (e.g., bending, reaching).

Background elements (shelves, walls, decorative items) remain stationary across frames. No fire, water, smoke, or wind-driven motion is observed.

A child in light-colored pajamas sits on a purple play mat, initially facing two illustrated cards (one depicting a colorful crab, the other a blue dragonfly) laid out in front. The child then turns toward an orange box to their right, reaching inside and pulling out small items while seated. The scene includes a gray couch with cushions and scattered shoes in the background. The camera maintains a top-down perspective with slight movement.

Child is moving: turning head, moving hands to interact with cards and book. Cards are being physically moved by the child's hands.

Background is static (couch, shoes, ball remain fixed). No fluid/environmental motion (fire, water, smoke, wind) present.


A person with dark long-sleeve sleeves places puzzle pieces into a partially completed African savanna scene jigsaw puzzle. The hands move from the bottom of the frame, picking up scattered pieces and fitting them into the right section of the puzzle, which includes lions and zebras. The puzzle gradually fills as the hands continue placing pieces around the lion's face and surrounding area. The camera maintains a top-down perspective throughout, showing the puzzle on a white surface with minimal background details.

The person's hands and puzzle pieces are moving. The hands are placing puzzle pieces onto the board, causing the pieces to be moved in discrete motions.

The background (white board and wooden table) is static and does not shift uniformly. There are no fluid or environmental effects (fire, water, wind) dominating the scene.


A man in a black shirt and red tie holds a bald baby in a banquet hall; the baby moves his hands upward and downward while the man looks around and gestures. A person in a red top sits to the man's left, and other attendees are seated at tables with decorations in the background. The camera remains stationary, capturing the scene from a medium distance.

Discrete solid objects (people) are moving via locomotion and gestures, including a man holding a baby and other social interactions.

Background elements (walls, windows, furniture) are stable with no uniform shifting or environmental fluid motion (fire, water, smoke, wind) detected.

The camera follows the movement in a medium shot, capturing the skater’s fluid motion against the rink’s red barrier. Background details are minimal, emphasizing the skater’s action.

A single skater in dark attire is moving across the ice rink, performing dynamic maneuvers including spins, glides, and controlled falls.

Background elements (wall, rail, signage) show no uniform shifting or fluid motion. No fire, water, smoke, or wind are visible in the scene.


RAW CAPTION: Got it, let's tackle this. First, I need to describe the video chronologically. The video shows people playing a game, maybe dodgeball? Let's see the sequence.

In the first frame, there are several people: some in red shirts, some in teal. They're on a gym floor with a climbing wall in the background. The action starts with a group moving. Let's track the movement.

At [0.0] seconds, people are scattered. Then in [1.0], they move towards each other. The person in red (maybe) throws something? Wait, the video shows them running and throwing. Let's check the frames.

Frame 0: Multiple players, red and teal. Some are moving. Then frame 1: group shifts, maybe a throw. Frame 2: more movement, some turning. Frame 3: players are in a line, maybe after a throw. Frame 4: they regroup. Frame 5: another throw.

Wait, the key is to note the motion. The main subjects are the players in red and teal shirts. Let's count: maybe 5-6 people. They're moving around the gym floor. The action involves running, throwing (maybe balls), and positioning.

Chronology: First, players move in various directions. Then, a player throws a ball (or object), others react. They regroup, run towards the goal (maybe the net in the background), and continue the game.

Appearance: Players wear red or teal shirts, black or dark pants. The gym has a wooden floor, climbing wall, basketball hoops.

Spatial relationships: Players are spread out, moving towards each other. When throwing, one is in front of the group. The goal (net) is on the right.

Camera: It's a fixed shot? Or slight movement? The video description says "slight shake" maybe, but need to check.

Wait, the rules say conclude with camera perspective and movement. The video is likely a fixed camera in the gym, maybe slight shake.

Let's structure the caption:

Start with the initial scene: A group of people (approximately 6) in red and teal shirts are playing a game on a gymnasium floor. They move dynamically; some run towards each other while others position themselves. Players in red shirts (with black shorts) and teal shirts (with black pants) alternate between throwing objects and evading. As the game progresses, they shift positions, with some moving toward the goal net visible on the right. The camera maintains a steady, overhead view with minor shake, capturing their rapid movements and interactions.

Wait, need to be concise. Let's check the rules: chronological paragraph. Focus on motion and behavior.

First, initial positions: group of people (red and teal) on gym floor. Then, they run towards each other. Then throwing (maybe), then regrouping.

Let me rephrase:

The video shows approximately six individuals wearing red or teal shirts and dark pants playing a fast-paced game on an indoor gymnasium floor. Initially, players scatter and move dynamically across the court; some run forward while others turn to face opponents. A player in a red shirt throws an object toward the group, prompting others to reposition. Subsequent frames depict continuous movement as players shift toward the goal net on the right, adjusting their stances. The camera maintains a fixed perspective with slight shake, capturing the players' coordinated actions and spatial reorientation.

Wait, need to count the number of players. From the frames, maybe 5-6. Let's say "approximately six".

Also, mention their appearance: red or teal shirts, dark pants (since some have black shorts/pants).

Check if the background is essential: minimal background, so just "gymnasium floor with climbing wall visible in the distance".

But the rules say "background descriptions minimal unless essential for understanding motion". The climbing wall isn't essential, so maybe just "gymnasium floor".

Let me draft:

In the video, six players wearing red or teal shirts and dark pants engage in a dynamic game on a gymnasium floor. They move rapidly, scattering and converging; a player in a red shirt throws an object toward the group, followed by others adjusting positions and moving toward the goal net on the right. The camera remains steady with slight shake, capturing their continuous motion and interactions.

Check if it's chronological: initial movement, throw, adjustment, moving toward goal.

Yes. Let's make sure it's concise.

Another version:

Approximately six individuals in red or teal shirts and dark pants play a game on an indoor gym floor. The players scatter and run toward each other, with one in a red shirt throwing an object. They then regroup and move toward the goal net on the right, adjusting positions. The camera maintains a fixed perspective with slight shake throughout.

That's good. Let's check all

Multiple players (wearing red and blue jerseys) exhibit distinct locomotion: running, jumping, and hitting the volleyball. The ball moves due to collisions with players' rackets and the net.

The gym walls, net, and court lines remain stationary throughout the video with no shifting or environmental motion (e.g., fire, water, wind). Background elements show consistent positioning without uniform displacement.
