A large group of uniformed band members in dark attire marches forward in synchronized steps, playing instruments; a flag bearer ahead carries a red flag with yellow accents, leading the procession. The band members maintain a tight formation, with some personnel visible in front and others trailing. The camera tracks the movement of the band, maintaining a steady focus on the advancing group.

Discrete objects include the marching individuals (people) and the flag bearer, moving in unison due to coordinated locomotion (walking), with no visible collisions or external force interactions beyond their own movement.

The background elements (e.g., standing spectators or structures) show no significant shifting or fluid motion; no fire, water, smoke, or wind-driven environmental effects are present.


A shirtless man in black shorts and dark sneakers hangs from a horizontal bar against a clear blue sky. He grips the bar, pulls himself upward, swings his legs forward, and shifts his body slightly to the right as he continues moving. The background features a distant fence and trees. The camera remains stationary, capturing the motion from a fixed angle.

A shirtless man in shorts is performing pull-ups on a horizontal bar, moving up and down with his body.

The background (sky, ground, trees) is static with no shifting. No fluid or environmental motion (fire, water, wind) dominates.


A girl with long dark hair, wearing a white and black top, sits in a striped armchair, holding a brown blanket. She shifts her position slightly, adjusting the blanket while seated. The table with a red and white striped cloth is behind her, with a lamp and bookshelves visible. The camera pans slowly around her, capturing her movements from various angles.

The person is the primary discrete object, moving their head and body in a manner consistent with voluntary motion (e.g., head movements, leaning forward/backward).

The background (bed, desk, lamp) remains stationary throughout the frames, indicating no ambient environmental motion (e.g., fire, water, wind).


RAW CAPTION: Got it, let's break down the video. First, there's a dog with brown and white fur, wearing a brown collar with studs. A hand is interacting with the dog's mouth. The hand moves towards the dog's teeth, then the dog opens its mouth, showing teeth. The hand then moves the dog's mouth or maybe the hand is inside the mouth? Wait, the sequence: in frame 0, hand near dog's mouth. Frame 1, hand touching teeth. Frame 2, dog's mouth is open. Frame 3, hand is inside the dog's mouth? Then frame 4, the dog's mouth is open wider, maybe the hand is still there. Then frame 5, the dog is moving its head.

Wait, need to describe chronologically. Let's list the actions step by step.

The video starts with a close-up of a brown and white dog wearing a brown collar with studs. A hand approaches the dog's mouth, then touches or interacts with the dog's teeth. The dog opens its mouth, revealing teeth, and the hand is inside the mouth area. The dog moves its head, and the hand adjusts position. The camera seems to be close-up, maybe handheld, slightly shaky.

Check rules: focus on motion and behavior, chronological.

So, first, the dog (brown and white, collar) has a hand approaching its mouth. Then the hand is near the dog's teeth, the dog opens mouth, then the hand is inside the dog's mouth, then the dog moves head.

Wait, the frames: frame 0 shows hand near dog's nose/mouth. Frame 1: hand touching dog's teeth. Frame 2: dog's mouth open, teeth visible. Frame 3: hand is inside the dog's mouth, maybe the dog is biting or the hand is holding. Frame 4: dog's mouth open wider, hand moving. Frame 5: hand is gone, dog moving head.

So the sequence: Hand interacts with dog's mouth (touching teeth), dog opens mouth, hand enters mouth, then dog moves head.

Now, appearance: dog is brown and white, collar. Number: 1 dog, 1 hand. Spatial: hand is in front of dog's mouth.

Background is minimal, just some floor tiles maybe.

Camera: close-up, probably handheld with slight shake.

Putting it together:

"A brown and white dog wearing a brown studded collar has a hand approach its mouth; the hand touches the dog’s teeth as the dog opens its mouth to reveal teeth, then the hand moves inside the dog’s mouth while the dog shifts its head; the camera maintains a close-up perspective with slight movement."

Check if that's chronological, mentions motion, appearance, spatial. Yes.

Wait, rules say "briefly describe their appearance and number". So dog: brown and white, collar. Hand: 1 hand.

So revised:

"A brown and white dog wearing a brown studded collar has a hand approach its mouth, touch its teeth, and enter its mouth while the dog opens its mouth and shifts its head; the camera remains close-up with slight movement."

But let's check the exact frames. In frame 0, hand is near the dog's mouth. Frame 1, hand is touching the teeth. Frame 2, dog's mouth is open (maybe the hand is still there). Frame 3, the dog is licking or the hand is moving inside. Frame 4, hand is moving away? Wait, frame 4: the dog is moving its head, maybe the hand is no longer visible. Wait, maybe the hand is interacting with the dog's mouth, the dog opens, then the hand is inside, then the hand moves away.

Wait, looking at the frames:

0: hand near dog's nose/mouth, dog's face up.

1: hand is touching the dog's teeth (close up of mouth).

2: dog's mouth is open, teeth visible.

3: hand is inside the dog's mouth (maybe the dog is biting or the hand is holding).

4: dog's mouth is open, hand is moving (maybe withdrawing).

5: dog's head is moving, hand is gone.

So the sequence: hand approaches, touches teeth, dog opens mouth, hand enters mouth, then dog shifts head.

So caption should be:

"A brown and white dog with a brown studded collar has a hand approach its mouth, touch its teeth, and enter its mouth as the dog opens its mouth; the dog then shifts its head while the hand withdraws; the camera maintains a close-up, slightly shaky perspective."

But need to make it concise. Let's check the rules: "concise, chronological paragraph".

So: A brown and white dog wearing a brown studded collar is interacted with by a hand that touches its teeth and enters its mouth as the dog opens its mouth and shifts its

A human hand is brushing the teeth of a dog; the dog's head moves slightly in response to the brushing action.

Background is static (dark surface and floor); no fire, water, smoke, or wind observed.


A person wearing a light-colored shirt adjusts four upright playing cards with blue and pink backs arranged in a bridge-like formation on a dark wooden surface; their hands reposition the cards, lifting one to realign it, while a small blue light glows near the right edge of the frame; the camera maintains a static top-down perspective throughout.

The person's hands are moving to manipulate and arrange the playing cards (building a card house). The cards themselves move due to being placed and adjusted by the hands.

The background (dark wooden table and tiled floor) is static with no shifting or fluid/environmental motion (e.g., fire, water, wind). The blue light on the table is fixed.


A shirtless toddler in white pants interacts with a lamp on a wooden surface, turning it on and holding the illuminated lamp close as the light brightens the room. The camera captures the child from behind and to the side with slight handheld movement.

The baby (discrete object) moves: initially near the cabinet, then reaches toward and adjusts the lamp, turns it on (increasing brightness), and subsequently moves away while interacting with the lamp and surrounding objects.

The background walls and cabinet remain static with no shifting or motion. No fire, water, smoke, or wind phenomena observed; the lamp's light is stationary after being activated.


A person wearing a white shirt manipulates a small, green, translucent object (likely a bottle) with their hands, rotating it to display various angles. The object is held in front of the person, with a dark background and a black chair partially visible. The camera maintains a close-up, stationary perspective, focusing on the hands and object throughout the sequence.

A person's hands manipulate a green glass bottle: opening it, squeezing, and tilting to pour liquid (though pouring is not fully visible, the bottle is being actively moved).

The background (black chair and wooden structure) is stationary. No fluid or environmental motion detected.


A woman in a dark top with a floral lei holds a small toy knife, pointing it toward a child in a green shirt seated at a table with a red cupcake; a man in a black shirt claps beside the child. The woman leans forward and blows out the candle on the cupcake, then turns away as the man stops clapping. The background includes a blue door with partial text and a decorated table. The camera remains stationary with minimal movement.

A woman, man, and child exhibit discrete movements: clapping, reaching toward the child, and minor positional shifts. These actions involve explicit physical forces (hand movements, interactions).

Background elements (walls, door, furniture) remain static; no fluid motion (fire, water, wind) or environmental effects are present.


A hand uses a brown brush to scrub a black sneaker with white accents, moving the brush along the shoe's surface over a container filled with a light liquid. The shoe is held above the container, and the hand repeatedly dips and wipes the shoe. The camera maintains a close-up, slightly shaky perspective focused on the cleaning action.

A hand (discrete object) is scrubbing a sneaker (another discrete object) with a brush; the motion involves physical contact and force application between the hand, brush, and shoe.

The background elements (newspaper, keyboard) are stationary and show no shifting or environmental fluid motion (e.g., no fire, water, wind).


A person in a gray long-sleeve shirt and dark shorts sits on the floor, using both hands to massage the bare foot of another individual whose leg is extended in front of them. The person in gray shifts their hands across the foot, moving them upward. The scene is viewed from a static top-down perspective with a bright, minimal background.

Two discrete objects: a person (sitting, massaging another's leg) and the extended leg. The person's hands and upper body show controlled motion from massaging actions.

No shifting background elements observed; scene is brightly lit but static with no visible fluid or environmental motion (fire, water, smoke, wind).


A small child in light clothing runs along a paved pathway marked with white lines, navigating past three orange traffic cones positioned in a line. The child progresses from the far end of the path toward the camera, passing each cone sequentially. Spectators stand on both sides of the path, some observing the child’s movement. The camera remains stationary, capturing the scene from a fixed perspective along the pathway.

A person is moving along a paved path, passing orange cones. The person's locomotion (walking) is the primary discrete object movement.

Background elements (trees, grass, pavement) show no uniform shifting or fluid motion; subtle tree sway is negligible and not dominant. No fire, water, or smoke observed.


A small child wearing a white and blue shirt and jeans sits on a green carpet, manipulating a wooden toy by moving their hands and adjusting its position. The child is positioned to the right of a large beige couch with a green cushion, with a bed featuring a purple blanket visible to the right. The camera remains stationary in a top-down perspective throughout.

The child and a dog exhibit minimal movement, which appears to be due to the child interacting with the animal.

No shifting background or fluid motion observed. The room's static elements (sofa, bed) remain fixed throughout the frames.


A person in a camouflage jacket and dark pants stands on snow, interacting with two black dogs. One dog digs in the snow to the left, while the other moves nearby. The person gestures with their hands and shifts position, maintaining engagement with the dogs. The camera remains static, capturing the scene from an elevated perspective with a snowy background.

A person (in winter clothing) is moving to throw a small red object (likely a ball), and a dog is interacting with the object. The person and dog exhibit solid, discrete motion driven by intentional locomotion and object interaction (e.g., throwing, chasing).

The snow-covered ground serves as a static background with no significant fluid motion (e.g., flowing water, billowing smoke) or wind-driven movement visible. The snow appears stable, with no indication of environmental fluid dynamics dominating the scene.


A hand moves from the right side of a worksheet across blue ink drawings, adjusting the paper's position and shifting it slightly left. The hand interacts with the paper’s edges, with the camera maintaining a top-down perspective and minimal movement throughout.

The background consists of a static paper surface with a hand-drawn diagram. No shifting backgrounds, fire, water, smoke, or wind are present.


A young boy in a light-colored checkered shirt stands beside an adult male in a blue shirt, both facing a chocolate cake topped with sprinkles and a blue candle. The adult male blows out the candle, then lifts his hand while the boy in the checkered shirt moves his hand toward the cake. A second young boy appears to the left of the first boy. The camera remains mostly static with slight shake, capturing the interaction in a well-lit indoor space.

Adult (blue shirt) moves hands (blowing, pointing, gesturing) toward cake; children (plaid shirt and partially visible) exhibit small head/body movements while observing the cake.

No significant background shifting or fluid/environmental motion (fire, water, wind) observed. Background (wooden floor, furniture, walls) appears static with no uniform displacement.


A hand adjusts a black microscope positioned to the right of a monitor, moving its base to shift the monitor's display from a coin's surface to circuit board components and other magnified details. The hand remains near the microscope stand, controlling its position. The camera maintains a static frontal perspective throughout.

A hand manipulates the microscope stand, causing visible displacement of the microscope's position. The monitor displays changing images (coin, circuit board), but these are screen content, not physical object motion.

No shifting backgrounds observed; the physical environment (monitor stand, microscope base, table) remains static. No fluid or gaseous motion (fire, water, smoke) present.


An individual in black pants and ice skates glides forward on an ice rink while holding a hockey stick, starting with a low-angle focus on their feet and stick, then the camera tilts upward to reveal their legs and torso as they push off the ice. The subject maintains a steady forward motion, with the rink's boards and advertisements faintly visible in the background. The camera perspective shifts from a low angle to a slight upward tilt, tracking the movement across the ice surface.

A hockey player (legs and stick) is moving on ice via skating motion and stick manipulation. Discrete solid object showing clear locomotion patterns with force application to the ice.

Background elements (rink boards, walls, and advertisements) are stationary with no shifting or environmental fluid motion. Ice surface is static with no visible water flow or wind effects.


A person in a pink shirt and blue jeans walks left across a brick patio, turns around, and walks right. The camera remains stationary in a top-down perspective.

A person (pink shirt, blue jeans) moves from right to left across the paved area, carrying a small object (likely a bucket/tool). Minor bending motion occurs when placing the object on the ground.

Background elements (building, bushes, paved area) are static with no uniform shifting. No fire, water, smoke, or significant wind-driven motion observed. Background remains consistent throughout.


A person with long brown hair, wearing a plaid shirt and jeans, crouches beside a fire pit, adding a reddish spice from a cloth bag into a black skillet resting on glowing coals. The camera zooms in to show the spice being sprinkled onto ground meat in the skillet, which sits among rocks and smoldering embers. Background greenery is visible but minimal. Camera transitions from a wide shot of the person to a close-up of the skillet.

The hand pouring liquid into the frying pan is the primary discrete object in motion. The hand and container exhibit controlled movement due to the person's explicit action of pouring.

The background consists of static rocks and vegetation with minimal movement. Smoke from the fire is present but not dominant; it is a secondary environmental element.


Two individuals sit facing the camera, a man in a black shirt on the left and a woman in a blue shirt on the right, each holding a guitar. The woman strums her guitar with her right hand while the man plays his guitar, their hands moving rhythmically over the strings. The camera remains static, capturing the scene from a frontal angle.

Two individuals (solid, distinct objects) are actively moving their hands to play guitars, demonstrating physical locomotion of body parts due to musical performance.

Static background elements (walls, furniture, window) show no uniform shifting; no fire, water, smoke, or wind motion observed.


A newborn with dark skin lies on a light-colored blanket. Initially, the baby’s eyes are closed, then they open briefly while blinking, and the mouth moves slightly. The camera maintains a close-up, handheld perspective with minor shakes, focusing on the baby’s face.

The baby is the only discrete solid object; it moves its head and face due to crying.

The background is a fabric blanket. No fire, water, smoke, or wind is present. The blanket shifts with the baby's movement, which is not a uniform shift of a fixed background element, so it does not indicate camera motion.


A girl in a black leotard and white tights sits on a tiled floor holding a pink ribbon, then stands, walks forward across the room, and another girl in a black leotard and white tights appears in the background. The camera remains stationary, capturing the dance studio’s blue walls and ballet barres.

Two dancers (primary subject and secondary background figure) exhibit discrete, solid-body motion: spinning, kicking, leaping, and handling a pink ribbon. Their movement is driven by explicit physical locomotion (e.g., leg extensions, arm movements, jumps).

The blue walls, white tiled floor, and metal railing in the background remain static across frames; no fluid motion (fire, water, smoke) or significant environmental effects are present.


A child in a purple shirt and teal pants walks and jumps across a colorful path of square mats (yellow, blue, red, green) on a gravel surface. A second child, wearing a white shirt and blue pants, enters from the right and steps onto the green mat. The scene takes place in a wooded area with playground equipment visible in the background, captured by a stationary camera.

Two children (one in pink, one in white) moving along a colored path: pink child hops/walks on squares (0.0-5.0s), white child enters at 4.0s and moves on green squares.

Background elements (trees, gravel ground, yellow/red buckets) remain stationary with no uniform shifting. No fire, water, smoke, or wind motion observed; all environmental elements are static.


Players in black and white jerseys skate on an ice rink, with black team members controlling the puck and advancing toward the white team’s defensive zone; they maneuver in front of and beside each other, passing the puck as white team defenders attempt to intercept; the camera pans left and follows the puck’s movement with a slight shake, capturing the flow of play across the rink.

Hockey players (in distinct uniforms) and a puck are moving. Players engage in skating, passing, and body checks, causing discrete motion. The puck is also in motion due to player interactions.

The background (rink boards, stands) shows minimal movement and no fluid motion (e.g., fire, water, smoke). Ambient environmental motion is absent.


RAW CAPTION: Got it, let's tackle this. The video shows a rotisserie setup, probably for cooking. First, the main subject is the rotisserie with meat on it. The meat is brown, looks like it's being cooked over a fire. The fire has embers, some red and purple, which might be from the heat. The rotisserie is a circular metal stand. The camera moves slightly, maybe panning or adjusting angle. There's a person in the background, but not much detail. Let's check the rules: focus on motion and behavior. The meat is rotating on the rotisserie, which is above the fire. The fire is burning, embers visible. The camera's perspective is close-up, maybe a slight pan. Need to mention the motion: the rotisserie spins, meat turns over the fire. Number of subjects: one main rotisserie with multiple pieces of meat. Spatial: meat on top, fire below. Background minimal. Let's structure: start with the rotisserie and meat rotating over the fire, describe appearance (brown, round pieces), then the fire with embers. Camera movement: slight pan or tilt, close-up. Avoid background details unless essential. So, the caption should be chronological: first the setup, then the motion. Let's draft: "A rotating metal rotisserie holds multiple brown, round pieces of meat over a bed of glowing red and purple embers, with the meat spinning slowly. A person in blue is partially visible behind the rotisserie. The camera slightly shifts angles to capture the rotating meat and the fire below, maintaining a close-up view." Wait, but rule e says minimal background. So maybe the person is not essential. Focus on the meat and fire. Let's adjust: "A metal rotisserie holds several brown, round meat pieces rotating above a bed of glowing red and purple embers. The meat spins slowly over the fire, with visible smoke rising. The camera slightly pans to follow the rotating meat, maintaining a close-up perspective." Check rules: motion (spinning), appearance (brown, round, embers color), spatial (meat on top, fire below). Camera movement: slight pan, close-up. Background minimal. Yes, that works. Let's make it concise. "A rotating metal rotisserie displays several brown, round meat pieces above a bed of glowing red and purple embers, which emits smoke. The meat slowly spins as the camera slightly shifts angles to capture the movement and fire below, maintaining a close-up view." Hmm, but maybe "d) conclude with camera perspective". So "The camera maintains a close-up view, slightly panning to follow the rotating meat over the fire bed." Let's combine. "A metal rotisserie with multiple brown, round meat pieces rotates over a bed of glowing red and purple embers, producing smoke. The meat spins slowly as the camera slightly pans to capture the motion and fire below." Wait, "chronological paragraph"—so order of events: first the setup, then the action (rotating), then camera. So: "The video begins with a metal rotisserie holding several brown, round meat pieces rotating above a bed of glowing red and purple embers. Smoke rises from the meat as it spins slowly. The camera slightly shifts angles, maintaining a close-up view of the rotating meat and fire." But "begins with" might not be necessary. Just describe the action. Maybe: "A metal rotisserie rotates multiple brown, round meat pieces above a bed of glowing red and purple embers, emitting smoke. The meat spins slowly as the camera slightly pans to capture the motion and fire below." Check length. Rules say concise. Let's see. Also, "main subjects": the rotisserie and meat. So "A rotating metal rotisserie holds several brown, round meat pieces over a bed of glowing red and purple embers. The meat spins slowly, emitting smoke. The camera slightly shifts to follow the rotation, maintaining a close-up perspective." That seems good. Let's check if it's chronological: the rotation happens first, then the camera moves. Wait, the camera movement is part of the video's progression. The video shows the rotisserie spinning, and the camera follows that. So the motion of the meat (spinning) is the main action, and the camera movement is how it's captured. So the caption should mention the meat spinning, then the camera movement. Let's make sure it's chronological: the meat is spinning, which causes the camera to adjust. So the order: the meat rotates, the camera follows. Yes. Now, check rules b: appearance and number. "multiple brown, round meat pieces" – number (multiple), appearance (brown, round). c: spatial – meat on rotisserie above fire. d: camera perspective (close-up) and movement (sl

Food items on rotating golden stand moving due to mechanical rotation of the display.

No shifting background elements detected; no fluid/environmental motion present.


RAW CAPTION: Got it, let's break down the video. First, the scene is a playground with a colorful hopscotch course. There are several kids. In the initial frames, a few children are standing at the start. Then, a boy in a gray shirt and black pants runs towards the hopscotch, stepping on the squares. Another child follows. Then, a girl in a white shirt with "PLAY AREA" (but we exclude text) runs over. Wait, no, the rules say exclude text recognition. So just describe motion.

Chronological order: First, kids at the start. Then, a boy runs across the hopscotch, steps on the squares. Another child (maybe the same or different) follows. Then, a girl in white runs over. Then, a boy in gray shirt runs again. The background has other kids and playground equipment.

Need to focus on motion: kids running, stepping on the hopscotch. Describe appearance briefly: boy in gray shirt, black pants, red shoes; girl in white shirt, dark pants. Number: multiple kids, maybe 3-4 visible.

Spatial relationships: the hopscotch is on the ground, kids moving from the top (where they start) down towards the camera. Camera is static? Or does it move? The frames show different angles, but the camera is probably stationary, just capturing the kids moving through the hopscotch.

Check the rules: exclude text, names, stylistic. So no "PLAY AREA" text. Just motion.

So putting it together:

Several children run across a colorful hopscotch course on a playground. A boy in a gray shirt and black pants steps onto the squares, followed by another child in a white shirt. A girl in a white top runs across the course, then a boy in gray steps onto the squares. Other children stand in the background near playground equipment. The camera remains stationary, capturing the kids' movement from the start of the course towards the camera.

Wait, check chronological: first, the initial scene with kids at the start (frame 0), then a boy runs (frame 1), another child (maybe the same or different) in frame 2. Then frame 3: a girl runs, frame 4: another child. Then frame 5: a boy runs.

So need to sequence: initial kids at the start, then a boy (gray shirt) runs towards the camera over the hopscotch, then a girl (white shirt) follows, then another child (maybe boy in gray shirt again) runs. The camera is static, no movement.

Let me structure:

In the video, multiple children move across a colorful hopscotch course on a playground. A boy in a gray shirt and black pants runs from the top of the frame toward the camera, stepping onto the squares. Another child in a white shirt follows, running past the course. A girl in a white top then crosses the hopscotch, and a boy in gray steps onto the squares. Other children remain near playground equipment in the background. The camera stays stationary, capturing the children’s movement along the course.

Wait, need to check for chronological order. Let's list the events:

Frame 0: kids standing at the start (top of hopscotch)

Frame 1: boy (gray shirt, black pants) runs toward camera on hopscotch

Frame 2: another child (white shirt) runs toward camera, then maybe a girl

Frame 3: a girl runs over, then a boy

Frame 4: a boy in gray shirt runs over

So sequence: children start at the top, then one by one run across the hopscotch course toward the camera.

Appearance: boy in gray shirt (small, child size), white shirt (child), girl in white top.

Number: multiple children, but main ones are the ones running.

Spatial: the hopscotch is on a reddish ground, the kids move from the top of the frame (where the course starts) down toward the camera.

Camera: remains static, no movement.

Exclude background details unless essential. Background has other kids, but minimal.

So final caption:

Several children run across a colorful hopscotch course on a playground. A boy in a gray shirt and black pants steps onto the squares, followed by a child in a white shirt. A girl in a white top crosses the course, then a boy in gray steps onto the squares. Other children stand near playground equipment in the background. The camera remains stationary, capturing the children’s movement along the course.

Children and adults are moving across the colored path via locomotion (walking/running), with distinct bounding boxes showing their position changes over time.

The ground features colored squares and static background elements (people standing in distance) with no fluid motion, fire, or significant environmental forces. No uniform background shift detected.


A small child wearing a yellow shirt sits at a table, holding a straw to their mouth while eating, then lowers their head slightly. Behind the child, a fish tank with green water and pink flowers is visible. The camera remains stationary but exhibits slight shaking.

The child is the primary discrete object moving (eating, shifting position). Fish inside the tank are also moving but are not dominant.

The background (purple wall, fish tank) remains static with no dominant environmental motion. The fish tank has contained water and fish movement, but it is not dominant.


A man in a dark green shirt and cap carries a large bouquet of white flowers toward a grave site. He approaches a crowd of people standing behind a rope barrier, bends down, and places the bouquet next to a white wreath already on the ground. The crowd observes the action, some with hands clasped. The camera remains stationary, capturing the scene from a ground-level perspective.

A person carrying a large bouquet of flowers is moving and placing it on the ground. Other people are standing stationary.

The background (trees, building, grass) is static with no shifting. No fire, water, smoke, or wind observed as dominant motion.


Hands stir a yellow egg mixture in a white bowl. Then, the hands move to press light brown grated bread on a white plate. The bowl is positioned to the left of the plate, and the camera maintains a top-down view with no significant movement.

Hands manipulating dough (solid, discrete object) in a bowl and on a plate, with clear physical interaction (kneading, shaping).

Background elements (white surfaces, bowl, plate) show no uniform shifting; no fire, water, smoke, or wind motion observed.


RAW CAPTION: Okay, let's tackle this video captioning task. The user wants a concise chronological paragraph focusing on the main subject's actions, appearance, spatial relationships, camera perspective, and excluding text and stylistic elements.

First, the video starts with a person in a kitchen. The main subject is a man wearing a black t-shirt with a logo. He's standing behind a counter with a yellow bowl, wooden cutting board, and some kitchen items. He's peeling potatoes. The camera shows him from a medium shot, then zooms in on his hands as he peels.

Looking at the rules: focus on motion and behavior chronologically. So, first he's standing, then peeling potatoes. The potatoes are yellow, maybe russet? The person's t-shirt is black with white text. The yellow bowl is on the counter. The camera moves from a medium shot to a close-up of his hands.

Need to mention the order: starts in the kitchen, then zooms in on peeling. Spatially, the yellow bowl is in front of him, cutting board on the counter. Background elements like the red kettle and green herbs are minimal, so maybe just note the kitchen setting briefly.

Check if text is excluded. The "Agradecimientos" text is mentioned, but rule f says exclude text recognition. So skip that. Also, no named characters or stylistic analysis.

Make sure it's chronological: the person is peeling potatoes, then the camera zooms in. The paragraph should flow from initial setup to the action. Mention the t-shirt color, potatoes' color. Avoid mentioning the brand names on the shirt unless they're part of the visual. Wait, the t-shirt has "rechupete" maybe? But the user says to exclude named characters, but the shirt's text is part of the visual. Wait, rule f says exclude text recognition, so maybe don't mention the shirt's text. Wait, the instructions say "Exclude text recognition, named characters, or stylistic analysis." So even if the text is visible, we shouldn't mention it. So perhaps just say "black t-shirt" without the specific text.

Wait, in the example, the user says "the person's black t-shirt" but not the logo. So we can describe the shirt as black without the logo. So focus on the action and appearance of the person: black t-shirt, holding potatoes.

The potatoes are yellow, two of them on the cutting board. The person is peeling one, then the other. The yellow bowl is on the counter.

Camera movement: starts as a medium shot, then zooms in to show hands peeling. Then maybe a close-up on the hands.

Need to structure the caption as: First, the person is standing in the kitchen, peeling potatoes. Then the camera zooms in on the hands. The yellow bowl is in front of the counter. The potatoes are yellow. The person's black t-shirt. Background has kitchen items but minimal.

Avoid mentioning the text like "Agradecimientos: Brandt", as per rule f.

So the caption should be:

A person in a black t-shirt peels two yellow potatoes on a wooden cutting board, with a yellow bowl positioned in front of them on a white countertop. The camera initially shows a medium shot of the person before zooming in to focus on their hands as they peel the potatoes, which are held over the board with peeled skin accumulating around the cutting board. The background includes a kitchen setting with visible appliances and utensils.

Wait, check for chronological order: starts with medium shot, then zooms in. So first the person is peeling, camera zooms in. The yellow bowl is in front. The potatoes are yellow, two of them on the board. The person's t-shirt is black.

Let me rephrase concisely:

A person wearing a black t-shirt peels two yellow potatoes on a wooden cutting board placed on a white countertop, with a yellow bowl positioned in front. The camera starts with a medium shot of the person then zooms in to focus on their hands peeling the potatoes, which are held over the board with peelings scattered around. The background includes a kitchen setting with various appliances and items visible.

But check if "various appliances and items visible" is too much. The rule says "background descriptions minimal unless essential". Maybe just "kitchen setting".

Also, need to mention spatial relationships: yellow bowl in front, cutting board on counter.

Wait, in the first frame, the person is standing behind the counter. The yellow bowl is in front of them. So "yellow bowl positioned in front of the person on the counter".

Also, the potatoes are on the cutting board. The person is holding them.

Let me check the example given in the problem statement. The user provided a sample video, but the instructions say not to include

A person's hands and a potato are moving; discrete solid objects interacting via peeling action.

Background elements (kitchen cabinets, countertops) remain static; no fluid motion (fire, water, smoke) or uniform environmental shifts observed.


RAW CAPTION: Okay, let me tackle this video caption request. First, I need to understand what the user is asking for. They want a concise, chronological paragraph describing the video, following specific rules. The main points are focusing on motion and behavior of main subjects, their appearance, spatial relationships, camera perspective, and minimal background.

Looking at the video frames provided. The first frame shows a person standing near a structure with laundry hanging. They're wearing a yellow hat, light-colored top, and shorts. There's a dog nearby. The second frame has the person moving towards the camera. Third frame, they're under a shelter. Fourth frame, the person is closer, interacting with the dog. Fifth frame, they're bending down, maybe petting the dog.

Wait, the user mentioned to describe in chronological order. So the sequence of actions: person starts standing, moves towards camera, approaches the dog, interacts (bends down), maybe pets the dog. The dog is present throughout. Let me check the frames again.

Frame 0: Person near a structure with clothes hanging, dog is there. Frame 1: Person moving towards camera. Frame 2: Under a shelter, person walking. Frame 3: Closer, person bending down. Frame 4: Person bending, reaching towards the dog. Frame 5: Person is now in a crouched position, hand near the dog.

So main subjects: person and dog. Person's appearance: yellow hat, light top, shorts, sandals. Dog: light-colored, maybe yellow. Spatial relationships: dog is near the person, the person moves towards it, then bends down to interact.

Camera movement: starts with a top-down or tilted view, then follows the person as they move. The last frame shows a slight shake or movement from the camera as it gets closer.

Background: minimal, but there's a structure with a roof, some chairs, plants. But rule e says to keep background minimal unless essential. So maybe just mention the structure and patio area briefly.

Need to structure the caption in chronological order. Start with the person standing, moving towards the camera, approaching the dog, bending down to interact. Mention the dog's presence and actions (like jumping or moving towards the person). Wait, in the frames, the dog is seen running towards the person maybe?

Wait in frame 4, the person is bending down towards the dog. So the dog approaches the person. Then in frame 5, the person is crouched, touching the dog.

Also, the camera perspective starts as a high angle (top-down?), then moves to follow the person, possibly with some shake.

Wait the user's example output might have the camera movement as "slight shake" or "following movement". Need to check the camera movement details. In the frames, the camera seems to be handheld, following the person's movement. So maybe "camera follows person's movement with slight shake".

Putting it all together: A person wearing a yellow hat, light top, and shorts walks towards the camera on a sandy patio, approaching a light-colored dog near a wooden shelter. The person bends down to interact with the dog, which moves towards them. The camera follows the person's movement from a top-down perspective with a slight shake, capturing the interaction.

Wait, need to check if the camera starts top-down or not. First frame shows a view from above, but the angle changes. The first frame is a bit tilted, so maybe the camera is handheld. The movement is following the person's motion.

Also, check the number of subjects: one person, one dog. Appearances: person's clothing, dog's color.

Avoid background details unless essential. So "sandy patio" might be essential as it's the location of action. The wooden shelter is part of the background but maybe mention "under a wooden shelter" to indicate the setting.

Wait, the user's rules say to keep background minimal. So maybe just mention "sandy patio" as the main setting.

Let me structure the paragraph:

A person wearing a yellow hat, light-colored top, and shorts walks towards the camera across a sandy patio near a wooden shelter, approaching a light-colored dog. The person bends down to interact with the dog, which moves closer. The camera follows the person's movement from a top-down perspective with a slight shake.

Wait, but the frames show the person moving from a distance towards the camera, so the camera is moving closer. Wait, the camera starts at a distance and follows the person. The first frame is a bit high angle, then as the person walks, the camera moves closer. So the camera's perspective is top-down initially but shifts as it follows the person.

Wait, maybe "camera starts with a high angle, then shifts to follow the person's movement with a slight shake."

But the user's rules say "conclude with the camera perspective and movement". So need

A person (climber) is moving upward on a concrete wall using their hands and feet. The motion is due to their own physical effort (climbing).

The background includes a concrete wall and vegetation which remain static. There are no fluid or environmental motions (fire, water, smoke, wind) dominating the scene.


A person in a white lab coat operates a blue and black device with hands, then shifts focus to a microscope where a hand adjusts the focus knob marked with numerical increments; the hand points to the knob while a small inset shows a different angle of the same component, and the word "Diaphrag" appears on the microscope base. The camera maintains close-up shots centered on the hand’s interaction with the microscope, with minimal background detail visible.

A hand is moving to adjust the microscope components (e.g., focusing ring, stage), demonstrating discrete, solid object motion due to physical interaction.

The background includes static elements like the microscope base and surrounding objects with no shifting or fluid motion (no fire, water, smoke, or wind).


A person in dark winter clothing bends over in the snow near a building's entrance, then stands upright, turns toward the door, and walks inside. The snowy ground surrounds the individual, who moves from a bent posture to a standing position and approaches the doorway. The camera remains static throughout.

A person in dark clothing is actively shoveling snow. The person moves their body (bending, lifting) and the shovel moves to push and throw snow. The motion is discrete and solid, with clear bounding box tracking.

The background (building, door, and ground) is static with no shifting. The snow is being displaced by the person's action, not by wind or other environmental fluid motion. No fire, water, smoke, or wind is dominant.


A hand holding a wooden spoon stirs a vibrant mixture of chopped vegetables—including red, yellow, and green bell peppers, carrots, and green beans—within a black frying pan. The hand moves the spoon in circular motions, blending the vegetables as they sizzle. The camera maintains a close-up perspective, focusing on the pan and the stirring action from a top-down angle with minimal movement.

Discrete solid objects include the wooden spoon, shrimp, carrots, zucchini, and peppers being actively stirred and moved by a hand.

No significant shifting background elements; no fire, water, or smoke visible. The background remains static with the wok and stove area.


Two individuals engage in an arm-wrestling match within a gym; one wears a light blue shirt, the other a gray shirt with a green cap, both gripping hands while leaning into the contest. A third person in a white cap stands between them, observing closely. The pair exert force, their arms locked as they strain against each other. Background spectators watch the match, with gym equipment visible but minimally described. The camera remains stationary throughout the sequence.

Two individuals are engaged in arm wrestling, with their arms and upper bodies moving due to physical force application. Additional spectators in the background exhibit minimal movement.

The background (including walls, equipment, and ceiling) shows no uniform shifting. There is no fire, water, smoke, or wind motion.


A child with dark braided hair and a pink top sits with their head bowed as an adult in a pink shirt adjusts the child's braids using their hands; the adult's hands move through the braids while the child remains still, positioned in front of a bookshelf. The camera tilts slightly downward and shakes, focusing on the interaction between the adult's hands and the child's hair.

Adult's hands actively braiding child's hair: repetitive motion of manipulating hair strands and securing with a green hair tie. Child's head shows minor positional adjustments during the process.

Background elements (shelf, floor) remain stable with no uniform shifting. No fire, water, or smoke present; environment is static.


A person in a dark shirt and light shorts stands near a pickup truck under a shelter at dusk. They turn, lift a large brown object, and walk left under the shelter past a green bin, exiting the frame. The camera remains stationary, capturing the scene from a fixed front perspective.

A person carrying a barrel moves from the right side towards the left, then exits the frame. The person's movement is tracked, with the barrel as a solid object in motion.

Background elements (poles, truck, trees) are stationary. No visible fire, water, or smoke, so no ambient environmental motion.


RAW CAPTION: Got it, let's see. The video shows a person playing a cello. First, identify the main subject: a person in a yellow shirt and red shorts. The cello is large, brown, with four strings. The person's hands are moving the bow across the strings. Let's break down the timeline.

In the first frame, the person is holding the bow, maybe starting. Then in subsequent frames, the bow moves across the strings, so the motion is the bow being drawn back and forth. The cello is positioned in front of the person, who's sitting (since it's a cello, usually played while seated). The background is minimal, a plain wall, so not much to describe. Camera perspective is close-up, focused on the cello and hands. No movement mentioned, so probably static.

Now, check rules: chronological order. Start with the person playing. Appearance: yellow shirt, red shorts, cello. Motion: bow moving across strings. Spatial: person in front of cello (wait, no, the cello is held by the person, so the cello is in front of the body). Camera is close-up, no movement.

So put it together. Start with "A person wearing a yellow shirt and red shorts plays a large brown cello, moving a bow across its strings in a back-and-forth motion. The camera remains static, closely focused on the cello and the bowing action."

Wait, need to be concise. Let's check the examples. The user wants a paragraph.

"From the close-up perspective, a person in a yellow shirt and red shorts plays a large brown cello, drawing a bow across its strings with repeated back-and-forth motions. The background is a plain wall, and the camera stays stationary, focusing on the bowing action."

Wait, but the rules say "briefly describe appearance and number". Number: just one person. The cello is one.

Check if spatial relationships are needed. The person is holding the cello, so the cello is in front of the person's body.

Also, "chronological paragraph". So start with the action: person playing cello, bow moving. Then describe camera.

Let me structure it: A person wearing a yellow shirt and red shorts plays a large brown cello, moving a bow across its strings in a rhythmic back-and-forth motion. The camera remains static, closely capturing the bowing action against a plain wall background.

Wait, the background is minimal, so "plain wall" is okay.

Wait, the video starts with the person holding the bow, so first action is bow moving. Let's make sure chronological order: starts with the bow in motion, then continues.

So the caption should be:

A person in a yellow shirt and red shorts plays a large brown cello, drawing a bow across its strings with repeated back-and-forth motions. The camera maintains a close-up, static perspective focused on the bowing action.

Yes. That's concise, chronological, mentions appearance (yellow shirt, red shorts, large brown cello), motion (back-and-forth bowing), spatial (close-up, static), background minimal (implied in "close-up perspective" but since background is plain wall, maybe include if essential. The rules say "minimal unless essential". Since the background is a wall, maybe "against a plain wall" but maybe not necessary. Wait, the user's example: the rules say "exclude text recognition, named characters, etc." So focus on motion.

Another angle: the person's hands move the bow, so "the person's hands move the bow across the cello strings in a back-and-forth motion".

Let's check the sample output format. The user wants a paragraph.

So:

<A person in a yellow shirt and red shorts plays a large brown cello, moving a bow across its strings in a continuous back-and-forth motion. The camera remains stationary, focused on the cello and bowing action without background details.>

Wait, but need to be concise. Let's see the rules: "chronological paragraph". Start with the action.

"From the close-up view, a person wearing a yellow shirt and red shorts plays a large brown cello, drawing a bow across its strings with rhythmic back-and-forth motions. The camera stays static, capturing the bowing action against a plain wall."

Yes, that's good.

Now, check if it's chronological: starts with the person playing, then the motion, then camera. Yes.

Also, mention spatial: "in front of" maybe not necessary. The cello is held, so the person is behind the cello, but the camera is close up on the cello and bow, so the person's torso is partially visible (yellow shirt, red shorts).

Wait, the first frame shows the person's arms and torso, so the cello

The person's hands (right hand holding bow, left hand on strings) move discretely across the cello to produce sound, with the bow vibrating the strings. These are solid, distinct objects moving due to physical interaction (bowing and finger pressure).

The background (wall and door frame) is static and unchanging throughout the video, with no fluid motion (fire, water, smoke) or wind effects. No environmental motion is present.


A person wearing a black crop top and dark skirt with gold embellishments performs a dance sequence inside a room. They begin with arms extended outward, then move their arms in a fluid, circular motion while swaying their hips. The individual remains centered in the frame, with a window, couch, and other room furnishings visible in the background. The camera maintains a stationary frontal perspective throughout the sequence.

A person (dancer) is performing belly dance movements, including hip swaying, arm movements, and body shifts.

The background (window, wall, chair) remains static with no shifting or fluid motion (e.g., fire, water, smoke).


A woman in a black tank top and gray leggings performs a squat with a barbell on a squat rack, while a man in a red shirt and black pants stands near a door. The man steps forward, walks toward the bench to the left of the rack, and bends down to adjust the bench. The background includes a standing fan and a window. The camera remains stationary throughout.

Two people: one exercising with weights (lifting motion) and another walking across the frame (locomotion).

Background elements (wall, fan, door frame) remain static with no fluid motion; no fire, water, smoke, or wind observed.


RAW CAPTION: Got it, let's tackle this. First, I need to describe the video chronologically. The main subject is a person on an ice rink. Let's check the frames.

In the first frame, the person is standing on the ice, maybe looking at something. Then they move—maybe stepping, then skating? Wait, the frames show the person moving around. Let's see: the person is wearing dark clothes, maybe a hat. The ice rink has windows in the background.

Frame 0: Person is on ice, maybe looking down. Frame 1: They move towards the left. Frame 2: More movement, maybe sliding or skating. Frame 3: They turn, still moving. Frame 4: Continue moving. Frame 5: Still moving, maybe skating around.

Appearance: Person is dressed in black (outfit), wearing a dark hat, black pants, and ice skates. They're the only person visible.

Motion: Chronological order—starts standing, then walks/ice skates across the rink, moves left, then right, continues to skate. Maybe the camera follows them? The background has large windows, so the rink is indoors.

Spatial: The person moves around the rink, so they are in the center, moving in various directions. The ice has some marks, but maybe not essential.

Camera: The camera seems to be a fixed position, maybe a bit shaky? Wait, the movement might be the person moving, not the camera. Wait, the problem says "camera perspective and movement". Let's see: the video shows the person moving, so the camera is probably stationary, capturing the person's movement across the frame.

Backgroud: Large windows with light coming through, the rink's walls. But minimal, as per rules.

Now, structure the caption:

- Start with the subject: A person in dark clothing (hat, black outfit, ice skates) is on an ice rink.
- Chronological motion: Initially standing, then moves leftward, turns, continues skating across the rink.
- Spatial: Moves across the ice, changing direction.
- Camera: Stationary, possibly with slight shake, capturing the person's movement.

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

"A person dressed in black with a dark hat and ice skates moves across an indoor ice rink. Initially standing, they glide leftward, then turn and continue skating in various directions. The camera remains stationary, capturing the individual’s motion against the backdrop of large windows."

Check rules:
a) Motion and behavior in chronological order: yes, starts standing, then moves left, turns, continues.
b) Appearance: dark clothing, hat, ice skates—correct.
c) Spatial: leftward, turns, direction changes.
d) Camera: stationary, possible slight shake (the video might have a bit of movement, but description says "stationary").
e) Background minimal: only mentioned as windows, which are part of the background but not essential.
f) No text, names, etc.

Wait, the video has a person moving, and the ice has some markers. Let's check frame 0: person is looking down, maybe at an object? Frame 1: they move towards the left. Frame 2: person is closer, moving. Frame 3: they turn, move right? Wait, frame 3 shows them from behind, then frame 4: they move right.

Wait, the description should be precise. Let's see the actual frames:

0: person in center, looking down at ice.

1: person moves left, ice surface has marks.

2: person closer, turning towards right.

3: person moving away, skates visible.

4: person skating further, maybe to the right.

So motion: starts standing (looking down), then moves left, turns, continues skating.

So the caption should be: "A person in dark clothing and a hat, wearing ice skates, stands on an ice rink. They then glide leftward, turn, and continue skating in various directions across the rink. The camera remains stationary, capturing their movement."

Check if it's concise. Let's adjust:

"A person dressed in black with a dark hat and ice skates moves across an indoor ice rink. Starting by standing, they glide leftward, turn, and continue skating in multiple directions. The camera is stationary, capturing their motion against the rink's windowed backdrop."

Wait, the rules say "briefly describe appearance and number". The person is one. "Mention spatial relationships if relevant"—the person moves left, then turns, so directions.

Final check: rules a-f.

Yes, this should work.
</think>

<caption_output>A person dressed in black with a dark hat and ice skates moves

A person rollerblading interacts with a small ball/puck, moving it across the ice through physical locomotion and contact forces. The person and ball exhibit discrete motion relative to the ice surface.

The indoor ice rink background (walls, windows, ice surface) remains static with no shifting or fluid motion; no fire, water, or smoke observed.


A person in a red shirt with black sleeves holds a brown dog's head, using a blue toothbrush to brush the dog's teeth; the dog wears a chain collar. The camera remains steady in a close-up shot.

A woman in a red uniform brushes a dog with a blue toothbrush-like tool; the woman's hand and the dog's head move discretely due to brushing motion.

Background elements (walls, medical equipment, shelves) are static and uniform; no fire, water, smoke, or wind observed.


RAW CAPTION: Got it, let's tackle this. The video shows a young boy on a dock fishing. First, he's standing on the wooden dock, wearing a red life jacket over a dark jacket and gray pants. He's holding a fishing rod. Then he reels it in, swings the rod, and the action is chronological. Need to describe his motions: starting with holding the rod, then casting (reeling in), then maybe the next action. Wait, the frames show him casting, so moving the rod. Spatially, he's on the dock by the water, trees in the background. Camera is probably stationary, slight shake? Wait, the rules say to note camera perspective. Let's check the video: the camera is at a medium distance, maybe following the boy's actions. Let's structure it.

First, the boy's appearance: young child, red life jacket, dark top, gray pants, standing on wooden dock. Actions: holds fishing rod, reels it in (tugs the line), then swings the rod to cast. Then the next frame shows him turning. Wait, the sequence is: he's holding the rod, then reeling (pulling the line), then maybe casting. Wait, in the frames given: [0.0] he's holding the rod, [1.0] same, [2.0] he's moving to cast (reeling in), [3.0] he's casting (swinging the rod), [4.0] he's holding the rod again, maybe after casting. So chronological: the boy stands on the dock, grips the fishing rod, reels the line in, then swings the rod to cast it into the water, and then returns to a stance holding the rod. Camera perspective is slightly shaky, medium shot, tracking his movements. Background has water and trees but minimal. Need to keep it concise, focus on motion. Let's draft:

A young child wearing a red life jacket, dark top, and gray pants stands on a wooden dock by a lake. He holds a fishing rod, reels in the line, swings the rod to cast it into the water, then adjusts his stance. The camera remains stationary with slight movement, capturing the child’s actions against the backdrop of calm water and distant trees.

Wait, check rules: "chronological paragraph", "briefly describe appearance and number", "spatial relationships", "conclude with camera". Let's make sure:

- Main subject: boy (young child, appearance as per rules)
- Actions: holds rod, reels, casts, adjusts stance.
- Spatial: on dock, water in front, trees background.
- Camera: perspective (medium shot, slight shake).

Also, exclude text recognition, named characters, so no "KID" or anything. Need to be concise. Let's try:

A young child wearing a red life jacket over a dark top and gray pants stands on a wooden dock. He holds a fishing rod, reels the line in, then swings the rod to cast it into the lake. After casting, he adjusts his stance, maintaining balance on the dock. The camera stays relatively stationary with minor shake, capturing the child’s actions against a backdrop of calm water and distant trees.

Check if background descriptions are minimal. The rules say "minimal unless essential for understanding motion". Since the motion is on the dock, water is essential, trees are background but maybe too much. Maybe "a lake" instead of "calm water and distant trees". Wait, the first frame shows trees, but maybe "calm lake with trees in the distance" but minimal. Let's see.

Another try: A small child in a red life jacket, dark jacket, and gray pants stands on a wooden dock by a lake. He holds a fishing rod, reels it in, swings to cast, and then returns to a standing position. The camera remains stationary with slight movement, focusing on the child’s actions against the lake and tree-lined background.

Yes, that's better. Let's confirm all rules:

a) Motion chronological: holds rod, reels, casts, stands.
b) Appearance: red life jacket, dark jacket, gray pants, small child.
c) Spatial: on dock by lake, trees in background (but maybe "by a lake with trees in the distance" is minimal).
d) Camera: stationary with slight movement.
e) Background minimal: yes, only necessary info (lake, trees).
f) Exclude text, names: no.

Final check: "A small child wearing a red life jacket, dark top, and gray pants stands on a wooden dock. He grips a fishing rod, reels the line in, swings to cast it into the lake, then adjusts his stance. The camera remains mostly stationary with slight shake, capturing the child’s actions against the calm water and tree-lined shore."
</think>

<caption_output>A young child wearing a red life jacket, dark top,

A child wearing a life vest is actively engaged in fishing, making deliberate movements with a fishing rod (casting, reeling) and adjusting their stance.

The background features a lake and trees with minimal water ripples; no dominant fire, smoke, or strong wind-driven environmental motion observed. The background elements (trees, dock) remain stable and do not shift uniformly.


Two men stand outdoors; the man in a pink polo shirt adjusts the collar of the man in a white dress shirt using both hands, while the other man remains still. The background features greenery and a building, and the camera maintains a stable perspective.

Two solid human subjects: one in a pink shirt adjusting the tie of another in a white shirt. The pink-shirted individual exhibits discrete hand movements while the white-shirted individual remains mostly stationary.

The background elements (trees, building, ground) remain stable across frames with no visible shifting or fluid motion (e.g., no wind-induced swaying of trees or water flow).


A person in a blue tank top and black shorts performs pull-ups on a horizontal bar. They hang from the bar, pull their body upward, lift their legs toward their chest, and momentarily lower slightly while maintaining grip. Blurred figures of other gym patrons are visible in the background. The camera remains stationary, capturing the motion from a fixed angle.

A person (male) is performing pull-ups on a horizontal bar, exhibiting clear up-and-down motion due to muscular exertion. This discrete solid object (the person) is the sole significant moving entity.

The background (walls, ceiling, gym equipment, and distant people) shows no shifting or fluid motion. No environmental phenomena (fire, water, smoke, wind) are present.


RAW CAPTION: Got it, let's break this down. First, the video starts with a grill. The main subject is the grill with charcoal and meat. Then a person is holding a foil tray with meat. The person is moving the skewers into the grill. Let's check the chronology: the first frame shows the grill with some meat, then the person places the foil tray, then puts the skewers on. Wait, the timestamps: 0.0 to 0.5 seconds, the first frame has the foil tray. Then the person starts putting the skewers on the grill. The hands are holding the skewers, which have meat, and they're placing them into the grill. So the action is the person inserting skewered meat onto the grill grates above the charcoal. The background has a stroller and a bowl, but maybe keep background minimal. The camera moves slightly, maybe panning or zooming in? The caption needs to be chronological. So: A person places skewered meat onto a charcoal grill, adjusting the skewers over the coals. The grill has glowing embers and existing meat skewers. The person uses tongs or hands to position the skewers. The camera focuses on the grill, moving slightly to capture the insertion of the skewers. Let's check rules: motion of main subject (person placing skewers), appearance (meat on skewers, charcoal), spatial: skewers being placed on the grill. Conclude with camera perspective: close-up, slight movement. Avoid background details unless essential. Background has a stroller but maybe not essential. So: In the video, a person places skewered meat onto a charcoal grill with glowing embers, adjusting the skewers over the coals; the grill holds several meat skewers, and the person uses wooden-handled skewers to position them. The camera maintains a close-up perspective, slightly shifting to focus on the placement of the skewers. Wait, the first frame shows the person holding a foil tray with meat, then they put the skewers on. So the sequence: 0.0: person holds foil tray with meat, grill has some skewers. Then the person places the new skewers into the grill. So the main motion is the person inserting the skewers. So: A person uses wooden-handled skewers to place seasoned meat onto a charcoal grill, positioning the skewers over glowing coals; the grill already holds several skewers, and the person adjusts their placement. The camera remains close to the grill, capturing the skewers being inserted into the grill grates. Let's make it concise. Check rules: chronological, main subjects (person, skewers, grill), appearance (meat on skewers, charcoal), spatial (skewers over coals), camera (close-up, slight movement). So the caption: A person places skewered meat onto a charcoal grill with glowing embers, using wooden-handled skewers to position them over the coals; the grill already contains several skewers, and the person adjusts their placement. The camera maintains a close-up view, slightly panning to capture the insertion of the skewers. Wait, the rules say "exclude text recognition, named characters, etc." So no mention of "person" but maybe "a person" is okay since it's the main subject. Wait, the rules say "focus on motion and behavior of main subjects (people/animals/objects)". So the main subject here is the person (object: hand) moving the skewers. So: A hand holds wooden-handled skewers with meat, inserting them into a charcoal grill with glowing coals; the grill already contains several skewers, and the hand adjusts their position over the embers. The camera provides a close-up perspective, slightly moving to focus on the skewers being placed. Hmm, but the first frame shows a person holding a foil tray. So maybe the first part is the person holding the foil tray, then placing the skewers. Wait, the video starts with [0.0] showing a person holding a foil tray with meat, then [0.5] the person is inserting skewers. So the action: the person transfers meat from the foil tray to skewers and places them on the grill. But the video might show the person already having the meat on skewers. Wait, the first frame: the person holds a foil tray with meat. Then in the next frames, the skewers are placed on the grill. So the sequence: person holds foil tray with meat (left side), then moves the skewers (with meat) into the grill. So the main motion: the person inserts skewers with meat into the grill. So: A person inserts skewered meat onto a charcoal grill with glowing coals, using wooden-handled skewers; the grill already holds multiple skewers, and the person adjusts their placement. The camera focuses closely

Skewers with meat are being rotated by a hand, and the hand moves as the skewers are adjusted.

Static background elements (person's legs, grill structure) show no uniform shifting; no dominant fluid/environmental motion (fire/glowing coals are secondary to object manipulation).


A person lies on their stomach on a bed, displaying tattoos on their back and leg. Another individual, wearing a black top and studded shorts, stands behind them and applies a white substance to the back using a cloth, moving it in circular motions. The camera remains stationary in a top-down perspective, capturing the interaction with minimal background details.

A person lying on a bed (static position) has another person applying a substance to their leg; the standing person's hands move discretely due to physical action.

Background elements (bed, wall) are stationary with no fluid environmental motion (fire, water, wind) or uniform background shifts.


RAW CAPTION: Got it, let's tackle this. First, I need to describe the video chronologically. There are two men working on a shed. Let's check the frames.

Frame 0: Two men, one in purple shirt, gray hat, dark shorts; other in dark blue shirt with yellow text (but exclude text), gray hat, dark shorts. They're near a beige shed. One holds a long wooden plank.

Frame 1: They move towards the shed's side. Maybe adjusting something.

Frame 2: One steps back, the other reaches up to the shed.

Frame 3: Both are moving, one bends down. The shed is being positioned maybe?

Frame 4: One man lifts a plank, the other is on the shed's side.

Wait, need to sequence actions. Let's list steps:

- Start: Two men (1 in purple, 1 in dark blue) stand near beige shed, each holding a long wooden plank.

- Then, they move around the shed. One bends down (frame 4), another climbs onto the shed? Wait frame 3: one bends, then frame 4: one lifts a plank, the other is on the shed's side.

Wait, the video shows them working on the shed. They are handling planks, maybe adjusting or positioning the shed. Let's make sure to focus on motion and behavior.

Chronological order:

1. Initial position: Two men (one in purple shirt, gray cap; one in dark blue shirt, gray cap) stand in front of beige shed, each holding a long wooden plank.

2. They move toward the shed's side, one steps back, the other reaches up to the shed's door area.

3. One man bends down near a tool box or chair, then both men adjust the planks, one lifts a plank while the other positions themselves against the shed.

4. The man in dark blue climbs up on the shed, while the other man holds the plank.

Need to check each frame:

Frame 0: Both standing, holding planks. Beige shed, wooden fence in background. Tools on left.

Frame 1: They move slightly, one bends down (maybe to get a tool), the other is by the shed.

Frame 2: One is closer to shed, the other steps back.

Frame 3: One bends down, the other is by the shed's side.

Frame 4: One is on the shed (maybe climbing), the other is lifting a plank.

Wait, the video shows them working on the shed, likely securing or positioning it. Let's capture the motion:

- The two men handle wooden planks around the beige shed. One man in purple shirt (gray cap) and another in dark blue shirt (gray cap) initially stand facing the shed. They move along the shed's side, adjusting the planks. One bends to handle tools or materials on the ground, while the other lifts a plank to position it against the shed. Eventually, one man steps onto the shed's side, using the plank for support.

Check for appearance: both male, casual wear, gray caps. Number: two. Spatial: in front of shed, moving around its side.

Background: wooden fence, tools, garden.

Now, make concise chronological paragraph.

Start: Two men (one in purple shirt, gray cap; one in dark blue shirt, gray cap) stand in front of a beige shed, each holding a long wooden plank. They move around the shed's side, with one bending to handle items near a chair and tool box, while the other lifts a plank toward the shed. The man in dark blue then climbs onto the shed's side, using the plank for support.

Wait, need to check frame 4: the man in dark blue is on the shed, lifting a plank, the other is on the ground.

Wait, the sequence:

- Frame 0: both holding planks, standing by shed.

- Frame 1: one moves toward shed, the other bends.

- Frame 2: they're moving, one near the shed, the other stepping back.

- Frame 3: one bends down, the other is by the shed.

- Frame 4: one man (dark blue) is lifting a plank while the other (purple) is on the shed's side, stepping up.

Wait, maybe the shed is being moved or secured, so the planks are supports.

The key is to describe the motions chronologically.

Final caption:

<caption_output>Two men, one in a purple shirt and gray cap, the other in a dark blue shirt and gray cap, stand in front of a beige shed, each holding a long wooden plank. They move around the shed’s side, with the man in purple bending to adjust tools near a chair while the other lifts a plank toward the shed. The man in dark blue then steps onto the shed’s

Two men are moving around the shed: walking, bending, and using tools. The shed appears to be moved by the men using poles, but the dominant motion is from the men themselves.

The background (fence, equipment) is stationary. No fluid or environmental motion (fire, water, smoke) is present. The ambient rule does not apply.


A man and a woman in black attire dance ballroom steps on a wooden floor, moving in synchronized rotations and steps across the room. The camera follows their motion with a slight pan, while other dancers remain in the background. The room’s wooden flooring and minimal background elements are visible, but the focus stays on the primary pair’s fluid movements.

Multiple dancers (couples) moving in coordinated dance steps.

No shifting backgrounds observed; no fire, water, smoke, or wind present.


RAW CAPTION: Okay, let's tackle this video captioning task. The user wants a concise, chronological paragraph based on the provided video frames. First, I need to parse the key elements from the frames.

Looking at the frames: The video starts with a view of underwater coral reef, then a person enters the frame. The person is a woman snorkeling, wearing a swimsuit and a snorkel mask. She's moving from the right side towards the coral. Her hand reaches out towards the coral, then she swims away, turning her back to the camera. The background is the reef and blue water, which is minimal per the rules.

I need to focus on the motion and behavior in order. The main subject is the woman. Her appearance: swimsuit color (orange and pink), snorkel mask with blue tube, black hair in a ponytail. She's the only person. The coral is the main background, but since it's essential, maybe mention it briefly.

Chronological order: starts with coral, then the woman enters from right, reaches out, swims forward, turns away. The camera movement seems to follow her, maybe panning left as she moves. The last frame shows her from behind, so the camera might be following her path.

Check the rules: keep background minimal unless essential. Coral is the environment, so maybe mention it as a backdrop. Spatial relationships: she's moving towards the coral, then past it. The camera perspective starts with a view of the reef, then shifts to follow the woman, ending with a rear view.

Need to exclude text recognition, named characters, etc. So no names or specific text. Also, the caption should end with camera perspective and movement.

Possible structure: A woman in a colorful swimsuit and snorkel mask swims towards a coral reef, extending her hand towards the coral before continuing to swim away. The camera follows her movement from a side perspective, transitioning to a rear view as she exits the frame.

Check for minimal background: "underwater coral reef" is necessary for context, but keep it brief. The camera movement: "follows her movement," "side perspective to rear view." Ensure it's chronological and concise.

Wait, the user's example shows the camera moving from the coral view to the person, then following her. So maybe the caption starts with the coral, then the person's action. The camera's movement is from the initial view of the reef, then panning to follow the woman.

Make sure to mention her orientation (swimming away, back to camera), her actions (reaching out, swimming forward). Avoid any mention of the video's technical aspects like frame numbers.

Check all rules: motion and behavior first, appearance (colors), spatial relationships, camera perspective. Conclude with camera movement.

Let me draft:

A woman in an orange and pink swimsuit and blue snorkel mask swims toward a dense coral reef. She extends her right hand toward the coral, then turns and swims away, her back facing the camera. The camera follows her movement from a side angle, transitioning to a rear view as she continues swimming through the clear blue water.

Wait, the video starts with coral, then the woman comes in. The first frame is coral, then frame 1 shows her reaching out. So maybe the caption starts with her entering the frame.

Revised: A woman in an orange and pink swimsuit and blue snorkel mask swims toward a dense coral reef, extending her right hand toward the coral. She then turns and swims away, her back facing the camera as the camera follows her movement from a side perspective to a rear view.

Check the chronology: first she reaches out, then swims away. The camera movement starts with her entering the frame from the right, following her as she moves.

Maybe: Starting with a view of a dense coral reef, a woman in an orange and pink swimsuit and blue snorkel mask enters the frame from the right. She extends her right hand toward the coral, then turns and swims forward, her back to the camera. The camera follows her movement from a side perspective, ending with a rear view as she swims away.

But the rules say background descriptions should be minimal. So maybe "dense coral reef" is okay as it's the main setting. Also, the woman's color details: orange and pink swimsuit, blue snorkel.

Check for conciseness. Let's make it shorter.

A woman in an orange and pink swimsuit and blue snorkel mask swims toward a coral reef. She extends her hand toward the coral, then turns and swims away, her back facing the camera. The camera follows her movement from a side perspective, transitioning to a rear view as she exits the frame.

Wait, "exits the frame" might not be accurate; in the last frame, she's still in the frame but moving away. The video has 5 frames, and in frame 5 she's swimming away

A snorkeler (discrete human subject) is moving through the water, exhibiting controlled locomotion with arm movements and body orientation shifts.

Coral reef background is static; water appears calm with no dominant turbulent motion (e.g., waves, currents) dominating the scene.


A person in a light pink shirt manipulates a metallic wire structure, placing it onto a table holding pink lilies, yellow sunflowers, and green succulents. They adjust the wire's position and arrange the flowers, moving their hands across the arrangement. The camera remains in a close-up, static view focused on the hands and floral setup.

Person's hands and arms are actively moving to arrange flowers in a glass container. Discrete objects (hands, flowers, vase) exhibit controlled motion due to physical manipulation.

Background elements (table, banner, static flowers) show no shifting or fluid motion. No fire, water, smoke, or wind effects observed in the environment.


A person in a black sweatshirt holds a bicycle tire, moving it toward a bicycle frame while adjusting its position near the chain; the bicycle's components and a cluttered workbench are visible. The camera remains static, capturing the action from a medium distance.

discrete_object_physics | ambient_environmental | camera_motion | ego_motion | static

Briefly describe what discrete, solid objects are moving.

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


A person in a blue jacket, blue cap, and black pants stands with a baseball bat held at the chest, knees slightly bent, facing a tee with a ball. They begin a swing, rotating their body and swinging the bat forward to strike the ball off the tee, sending it forward. To the left of the person, a white bucket and white base lie on the green turf. The camera remains stationary, capturing the motion in a medium shot.

The person (swinging a bat) and the ball (after being hit) are discrete objects moving due to explicit physical forces (the swing and the collision).

The background (walls and ground) is static throughout the video. No fluid/environmental motion (fire, water, smoke, wind) is present. The circular vignette effect at the end is a video edit, not a background shift.


A person wearing a pink helmet, black shirt, black pants, and knee pads rides a green skateboard with red wheels along a paved road, moving from left to right. She maintains balance with outstretched arms, adjusting her stance as she progresses. The camera follows her movement, capturing her motion from a slightly low angle with minimal background detail.

A child wearing a pink helmet and black clothing is riding a skateboard, moving along the road with clear locomotion (pushing off and gliding).

The background consists of static trees, grass, and a fence with no fluid motion (fire, water, wind) observed. The environment is calm and the background does not exhibit significant shifting.


RAW CAPTION: Got it, let's tackle this captioning task. First, I need to watch the video and note the main elements. The video shows two men playing clarinets. They're both in black outfits. The first frame has them standing, and they're playing. Let's check the sequence.

In the first few seconds, the two musicians are performing. They're side by side, maybe the one on the left is slightly in front? Wait, the video starts with them both playing, and their posture is consistent. They're holding clarinets, which are woodwind instruments, silver or dark? Clarinets are usually wooden or grenadine, but in the video, they might look like they have a shiny finish.

Looking at the background, there's a piano or something, but the background is minimal. The audience is in the foreground, but we don't need to describe them much. The main subjects are the two clarinet players.

Chronicling the motion: they're playing their instruments, moving their fingers on the keys, blowing into the mouthpieces. The camera is probably stationary, since it's a tight shot on them.

Wait, the video starts with them in position, and throughout the clip, they continue playing. Let's structure the caption:

Two men in black attire stand side by side, playing clarinets. The man on the left is slightly in front, both holding their instruments with focused postures, fingers moving over keys as they perform. The camera remains stationary, capturing their upper bodies against a softly lit indoor backdrop with a faintly visible piano in the background.

Wait, need to check if the camera moves. The problem says "conclude with camera perspective and movement". The video frames don't show any movement, so camera is stationary. Also, "briefly describe appearance and number: color (black), size (two men, similar height), orientation (standing, playing)."

So putting it all together: Two men dressed in black stand facing forward, playing clarinets. The man on the left is positioned slightly ahead of the man on the right, both using finger movements to play their instruments. The camera remains fixed, capturing them from the front in an indoor setting.

Wait, check the rules: a) motion and behavior in chronological order. So first, they're standing and playing. The clip shows them performing, so the chronological order is the sequence of playing. So start with them playing, maybe mention the action.

Let me draft:

Two men in black suits stand side by side, each holding a clarinet. The left man is slightly forward, both playing with focused postures; fingers move over keys as they perform. The camera remains stationary, capturing their upper bodies against a softly lit interior background with a faint piano visible.

Wait, "background descriptions minimal unless essential". The piano might be essential, but maybe not. The problem says "minimal". So maybe just say "indoor setting".

Wait, the first part of the video: they're in a room with people in the foreground, but the background is a wall and maybe a painting. But the rules say minimal background.

Let me check the example. The user's example would have to be concise.

Alternative: Two clarinetists in black attire play their instruments, standing adjacent to each other. The left musician is slightly in front, both moving fingers on their clarinets as they perform. The camera stays static, focusing on their upper bodies within an indoor space.

Wait, but need to include "conclude with camera perspective and movement". So the camera is stationary, as the frames don't show movement.

Let me try to make it as concise as possible.

"Two men in black suits play clarinets side by side; the left man is slightly ahead, both moving fingers on their instruments. The camera remains stationary, capturing them in an indoor setting."

Wait, "chronological paragraph"—since the video is a short clip, the sequence is them playing from start to end. So the motion is playing, fingers moving.

Another check: "number (color, size, orientation)". So two men, black color, size (probably medium, but not specified—just "two men in black attire").

"Spacial relationships": left man is in front of right man, or side by side with left slightly ahead.

So final draft:

Two men in black suits stand side by side, the left man slightly ahead, each playing a clarinet. Their fingers move across the keys as they perform, while the camera remains stationary, capturing them from the front in an indoor environment.

Yes, that seems to meet the rules. Let's check all rules:

a) motion and behavior: playing clarinets, fingers moving, chronological (they play throughout the clip).

b) appearance: two men, black suits, size not specified but implied.

c) spatial: left slightly ahead of right.

d) camera: stationary,

Two musicians are playing clarinets with slight movements (hand and body motion). Audience in foreground shows minimal movement.

Background is static (wall, piano) with no shifting or fluid/environmental motion. No fire, water, smoke, or wind visible.


In a gymnasium with wooden flooring and red bleachers, several individuals walk across the basketball court from right to left; a person in dark clothing moves centrally, accompanied by others in light-colored shirts, some turning direction. The camera pans left, tracking the group’s movement, with slight shake as it captures their motion against the backdrop of banners and a large decorative wall feature.

Discrete solid objects (people) are moving via locomotion (walking, positioning) on the basketball court. Their motion is consistent with human movement and physical interaction.

Background elements (walls, banners, basketball hoop) remain static across frames with no uniform shift or fluid motion detected. No fire, water, smoke, or wind-driven environmental motion present.


A person in a dark shirt holds a green flute vertically with both hands, their fingers positioned over the holes. The hands adjust slightly, demonstrating finger placement on the flute. The camera maintains a close-up, static perspective focused on the hands and instrument, with minimal background visible.

The person's hands are making discrete movements to manipulate the green flute, indicating solid object motion due to explicit physical interaction.

Background elements (walls, floor) appear static with no significant shifting or environmental motion (fire, water, smoke, wind).


A person in a dark shirt with a giraffe graphic plays a brown violin, holding it under their chin and moving the bow across the strings with their right hand while their left hand adjusts finger positions on the neck. A piano is visible to the left. The camera remains stationary with slight movement.

A person playing the violin exhibits discrete motion: bow hand moves across strings, left hand shifts positions on the fingerboard; the violin and bow are solid objects undergoing controlled, physical motion from playing technique.

The background (walls, window, furniture) is static with no fluid motion (fire, water, wind) or significant environmental shifts; no ambient elements dominate the scene.


A hand uses a spoon to add dark powder to a white mixture in a metal bowl, then stirs the contents in a circular motion to blend the ingredients. The bowl rests on a blue surface with tiled walls in the background. The camera maintains a top-down view throughout the sequence.

A hand and a spoon move as discrete solid objects in a controlled stirring motion within the bowl, driven by manual force.

No shifting background elements (tiles and blue surface remain static); no fire, water, smoke, or wind motion observed.


A hand squeezes a red and white bottle, dispensing liquid onto a white surface. The same hand then uses a white cloth to wipe a beige toilet seat, moving the cloth in circular motions. Next, the hand holds the red and white bottle, spraying its contents onto a white surface. The camera remains in close-up throughout, capturing the actions from a direct frontal perspective with slight adjustments to follow the hand movements.

A hand and a cleaning cloth are moving; the hand sprays cleaner and wipes the surface, demonstrating controlled motion due to human action.

The background (sink fixture and surrounding area) is stable with no shifting elements or fluid motion (fire, water, wind) observed.


RAW CAPTION: Okay, let's tackle this video captioning task. The user provided a video with several frames showing a snowy scene. My job is to create a concise, chronological paragraph following their rules.

First, I need to focus on the motion and behavior of the main subjects. The video starts with a close-up of a snow-covered slope where a person is skiing. The initial frame shows someone in dark clothing moving down the hill. Then the scene shifts to a wider view, showing the skier navigating through trees and a more open area. The skier seems to be moving downhill, possibly making turns or adjusting their path.

Next, the appearance and number of subjects. The skier is wearing dark clothing, maybe a jacket and pants. The video is in black and white, so color isn't a factor here. There's only one person visible in the frames. I should mention their size relative to the snow slope—since it's a slope, the skier is probably small in the frame compared to the snow-covered terrain.

Spatial relationships: The skier starts on a slope, then moves towards the camera or away? Wait, the first frame shows them on the slope, then as the video progresses, they move through the snow. The background includes trees and maybe other skiers in some frames, but the user said to keep background minimal unless essential. The trees are in the background, so maybe mention them briefly.

Camera perspective and movement: The video starts with a close-up (top-down?), then pans to follow the skier. The camera might be handheld, causing slight shake. The transition from close-up to wider shots suggests the camera is moving to track the skier's path.

Check the rules: Exclude text, named characters, stylistic analysis. Keep background minimal. So mention the trees only if necessary for understanding motion. The skier is moving downhill, turning, perhaps.

Chronological order: Frame 0: skier on slope. Frame 1: moving through snow. Frame 2: skier in motion. Frame 3: approaching trees. Frame 4: skier moving past trees. Frame 5: wider view of skier on slope.

So the sequence is: a skier in dark clothing descends a snowy slope, navigating through snow-covered terrain, passing by trees, with the camera following their movement.

Wait, the user said "briefly describe their appearance and number (color, size, orientation)". Since it's black and white, maybe mention "dark clothing" as appearance. The skier is likely small in frame due to the slope's size.

Spatial: The skier is on the slope, moving forward, with trees in the background. The camera follows them, panning and possibly shaking.

Conclude with camera perspective: The camera starts with a close-up, then pans to follow the skier, possibly handheld causing slight shake.

Wait, in the frames, the first frame shows a close-up of the slope, then the skier is seen moving, so the camera might be moving to track them. The user says "conclude with camera perspective and movement".

Check if background is essential. The trees are in the background, but maybe they are part of the scene. Since the skier is moving through snow, trees in the background might be relevant for the setting.

Putting it all together: A single person in dark clothing skis downhill on a snow-covered slope, navigating through snow and passing trees in the background. The camera follows the skier's movement, panning left and slightly shaking.

Wait, the frames show the skier moving from right to left or left to right? Looking at the frames: in frame 0, skier is on the slope. Frame 1, they move through snow. Frame 2, skier continues. Frame 3, maybe turning. Frame 4, moving towards trees. Frame 5, further along.

Wait, the user's examples might have the camera panning to follow the skier. Let me check the frames. The first frame shows the skier in a close-up, then as the video progresses, the skier moves away from the camera, then turns, etc. So the camera is tracking the skier.

So the caption should be chronological: The video shows a person in dark winter clothing skiing downhill on a snow-covered slope. Starting from a close-up view, the skier moves through the snow, passing trees in the background while adjusting their path. The camera pans left to follow the skier, maintaining a slight shake as it tracks their descent.

Check for rules: appearance (dark clothing), number (single person), motion (skier moving downhill, adjusting path), spatial (trees in background), camera movement (pans left, slight shake). Background minimal—trees are mentioned but as part of the scene. The video is black and white, so color isn't a factor.

Avoid text, names. Concise paragraph

The primary discrete object is a snowboarder moving down the slope. The snowboarder is clearly visible and moves in a controlled manner, making turns and descending the hill. Other people (skiers or snowboarders) are also visible in the background but are less prominent.

The background consists of static trees and snow. There are no environmental fluid motions (water, fire, smoke) or significant wind effects. The snow on the ground is not flowing, and the trees are stationary.


A hand with a white wristband pours liquid from a blue bottle into a white container near an open washing machine drum. The hand then places the blue bottle into the drum, which contains white and blue garments. The camera captures the action from a close-up perspective, shifting to show the bottle positioned inside the machine with the drum's interior visible.

The person's hands (wearing an orange sleeve and wristband) and laundry items (clothes) are moving. The hands pour detergent into the drum and interact with the clothes, while the clothes shift within the drum due to the washing process.

The washing machine structure and surrounding environment show no significant shifting background elements. No fire, water flow (beyond the machine's internal drum), smoke, or wind-driven motion is evident. The water inside the drum is part of the machine's operation, not ambient fluid motion.
