RAW CAPTION: Got it, let's break this down. First, the video starts with a person in a red shirt holding a large red balloon. They bring the balloon close to their face, then move it away. The person's shirt has text, but we can't mention text. The background has a red couch, framed pictures, and a door. The main motion is the person manipulating the balloon: holding it up, covering their face, then moving it around. Need to describe the sequence chronologically.

First frame: person holds balloon up to face. Then they move the balloon away, revealing their face. Then they hold it again? Wait, the video clips: frame 0, they have hands on balloon. Frame 1, hands still on balloon. Frame 2, they let go, balloon is near face but then they move it. Wait, the user provided frames: [0.0], [1.4], [2.5], [3.6], [4.7]. Let's check the actions.

Frame 0: person holds large red balloon in front of face, hands on it. Frame 1: balloon is still near face, but maybe starting to move. Frame 2: they lift the balloon up, so it's in front of them. Frame 3: balloon is held up, then moved. Frame 4: they let go, so the balloon is being held, then they move their hands. Wait, the description: "a person in a red shirt holding a large red balloon. They bring the balloon close to their face, then move it away."

So chronological: Initially, the person holds the large red balloon close to their face. They then move the balloon away from their face, holding it in front of them. The background includes a red couch and framed artwork, but we need to keep background minimal. The camera perspective: the video is shot in a fixed position, so no movement. The main subject is the person and the balloon.

Now, following the rules: focus on motion and behavior, chronological. Main subject: one person (red shirt, long hair), one red balloon (large, rounded). Actions: starts with balloon near face, then moves it away, holds it up, then moves it around. Wait, the frames show: frame 0: hands on balloon, covering face. Frame 1: hands still on balloon. Frame 2: they pull the balloon back, so it's in front of their face. Frame 3: balloon is held up, then in frame 4: they are holding it but maybe moving it. Wait, the exact sequence: "a person in a red shirt holds a large red balloon up to their face, then lowers it and moves it to the side, revealing their face, and then holds it again." Wait, looking at the user's provided frames:

Frame 0: [0.0] person with hands on balloon, covering face.

Frame 1.4: person still holding balloon, but maybe moving it.

Frame 2.5: person lifts the balloon up, so it's in front of them, not covering face.

Frame 3.6: balloon is held up.

Frame 4.7: person is holding the balloon, perhaps moving it to the side.

So the motion is: the person initially holds the balloon close to their face with both hands, then moves the balloon away from their face, holding it up in front of them, and then moves it to the side.

Now, describe that.

Appearance: person has long hair, wears red shirt. Balloon is large, red, rounded.

Spatial relationships: the balloon is held in front of the person's face initially, then moved to the side.

Camera: fixed perspective, no movement.

Background: minimal, but mention red couch and framed pictures only if essential. But rule e says minimal unless essential. Since the person is the main subject, background is secondary. So maybe just mention the setting as a living room with a red couch, but keep it minimal.

Putting it all together:

A person with long hair in a red shirt holds a large red balloon up to their face, then moves the balloon away, holding it in front of them and shifting it to the side. The balloon is large and rounded. The scene is set in a room with a red couch and framed artwork in the background. The camera remains static.

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

The person, wearing a red shirt with long hair, initially holds a large red balloon close to their face, then moves the balloon away, holding it in front of them and adjusting its position. The balloon is large and rounded. The camera remains fixed throughout the sequence.

Yes, that's better. Avoid background details unless essential. The background here is a red couch

A person interacts with a red balloon: inflating it, moving it across the frame, and manipulating it with hands. The balloon and person are distinct solid objects exhibiting motion due to physical forces (inflation, hand movements).

The background (red couch, framed pictures, door) shows no shifting or fluid motion; no fire, water, or wind present.


A person polishes a brown leather dress shoe using a white cloth; the left hand holds the shoe steady while the right hand moves the cloth across the shoe's surface. A white bottle with a blue label sits to the left of the shoe on a dark table. The camera begins with a close-up of the hands and shoe, then pulls back to reveal the full workspace.

The hands and polishing cloth move in discrete, controlled motions across the shoe surface. The shoe remains stationary while the cloth applies polish through back-and-forth rubbing motions. The polish bottle is fixed on the table.

No shifting background elements; no fluid/environmental motion (fire, water, smoke, wind) observed. The table and floor remain static throughout the frames.


A person wearing a black shirt and large over-ear headphones speaks into a microphone, their head tilting slightly and mouth moving as they converse. The camera maintains a close-up perspective with minor shifts, focusing on the upper body and face as the individual continues speaking.

A single person wearing headphones is moving their head and upper body slightly (e.g., nodding, shifting gaze), representing discrete solid-object motion due to speech/gestures.

Static background elements (text, logos, and microphone stand) show no uniform shifting; no fluid/environmental motion (fire, water, smoke, wind) is present.


In a kitchen setting, a woman in a sleeveless top and patterned skirt leans over a table with plates and cups, interacting with a seated person in front of her. A man in a white tank top and dark pants stands in the background near a doorway. The woman moves her right arm, adjusting the plate, while the seated person shifts position, leaning back. The man remains stationary throughout. The camera maintains a slightly shaky, eye-level perspective focused on the table interaction.

Discrete objects: Three people (one standing in background, one seated at table, one standing near table) moving via physical actions (gesturing, leaning, stepping back, eating).

Background (cabinets, doors, walls) remains static with no shifting or fluid motion; no fire, water, smoke, or wind present.


A person in a red shirt and blue jeans lifts the lid of a wooden box resting on straw, revealing a pile of grayish leaves inside. The camera captures the motion of the lid being raised and focuses on the contents within the box, maintaining a close perspective as the action unfolds.

A person's hand (wearing a red sleeve) manipulates a wooden box, lifting its lid and inspecting the contents. The box and hand exhibit solid, discrete motion due to physical interaction.

The background consists of dry grass and earth, which remain static with no significant fluid or environmental motion (e.g., wind, smoke, water). No fire, water, or wind is visible.


A person wearing a patterned shirt and black apron adjusts a tall glass vase on a kitchen counter, moving it slightly while focusing on its contents. To the right of the vase, a large green plant with white flowers stands on the counter. The background includes wooden cabinets and a window with blinds. The camera remains stationary, capturing the scene from a direct frontal perspective.

A person is moving their hands to arrange flowers in a vase; the person's body remains mostly stationary but hand movements are distinct.

The background (kitchen cabinets, window, refrigerator) is static with no shifting. No fluid or environmental motion (fire, water, smoke, wind) observed.


A person wearing a white chef's coat rolls a seaweed-wrapped sushi roll filled with rice and ingredients using their hands, then holds up the completed roll. The camera starts with a close-up of the hands shaping the roll and transitions to a medium shot of the person presenting it.

Chef's hands manipulate a sushi roll (discrete solid object), adjusting its position and orientation through deliberate movements. The sushi roll itself is rotated and held firmly, with no fluid motion.

The kitchen background (refrigerator, equipment) remains static with no shifting motion. No fire, water, smoke, or wind is visible; environmental elements are absent.


A silver toaster oven with a blue indicator light sits on a kitchen counter, containing golden brown cookies on aluminum foil. A hand in a red sleeve reaches from the left to open the oven door, then pulls out the baking tray. The camera remains stationary, capturing the action from a frontal perspective.

A human hand (discrete solid object) moves to open the oven door, revealing baked goods inside. The hand's motion is distinct and driven by intentional physical action.

No shifting backgrounds or fluid/environmental motion observed; static background elements (oven, red cups) remain fixed throughout the clip.


A person in a yellow shirt and floral pants sits on a chair, lifting a dry branch with leaves to their face, holding it near their eyes before lowering it. To their left, a table holds a laptop and water bottle. The camera remains static.

The woman's hands and yarn are the only discrete objects in motion, with clear, deliberate movements as she manipulates the yarn for knitting/crocheting. The laptop, water bottle, and table remain static.

The background (fence, trees, and bench) shows no shifting or fluid motion. No fire, water, smoke, or wind is visible; all elements are static and stable throughout the clip.


RAW CAPTION: Got it, let's tackle this. First, I need to understand the video frames. The first frame shows a person in a blue shirt working at a table with an iron, books, a printer, etc. Then the next frames zoom in on hands working with a piece of fabric and a tool, maybe an ironing pad.

Chronological order: Start with the person at the table. Then close-up on hands manipulating a gray object (maybe fabric) with a tool. Then a wider shot of the person again. Wait, the frames are [0.0], [1.4], [2.5], [3.6], [4.7]. Let's list each:

0.0: Person in blue shirt, sitting at table. Table has iron, books, printer, photos on wall. Window blinds.

1.4: Close-up of hands on fabric (gray, maybe a patch) with a tool (like a brush or something). Background has books, purple stuffed toy, yellow tool.

2.5: Hands still working on fabric, moving the tool over it.

3.6: Person adjusting the fabric, maybe the iron is involved.

4.7: Back to wider shot, person in blue shirt, same table setup.

Now, main subjects: person (blue shirt), hands, fabric (gray), tool (yellow? maybe brush).

Motion: The person is working on the fabric, possibly ironing or pressing. The camera starts with a wide shot, then close-up on hands, then back to wide.

Spatial: The person is at the table, hands on fabric. Background has books, stuffed toy, etc. But rule e says minimal background unless essential. So maybe mention the table setup briefly.

Chronological: First, person works at table. Then close-up of hands manipulating fabric with tool. Then return to wider shot of person.

Camera perspective: Starts with medium shot (wide), then close-up (top-down? the second frame is a close-up of hands on table), then back to medium shot.

Now, following the rules:

a) Focus on motion and behavior in order. Person is working on fabric (ironing/preserving). Hands move the tool over the fabric.

b) Appearance: person in blue shirt, hands, gray fabric, yellow tool (maybe).

c) Spatial: hands on the fabric placed on the table.

d) Camera: starts medium shot, then close-up (top-down? the second frame is close-up of hands, so top-down on the table), then medium shot.

e) Minimal background: books, stuffed toy in background, but maybe only mention if essential. The main action is the hands working, so background can be brief.

f) Exclude text, names, etc.

g) Don't output reasoning.

Putting it together:

The video opens with a person in a blue shirt sitting at a table, adjusting fabric on an ironing board. The camera then zooms in to show the person’s hands manipulating a gray fabric patch with a small brush over a maroon towel, surrounded by books and a purple stuffed toy. The person continues working on the fabric, then the camera pulls back to the original medium shot of the person at the table with a printer and window blinds in the background.

Wait, need to check timing. The frames: 0.0 is wide shot, 1.4 is close-up, 2.5 close-up, 3.6 person adjusting, 4.7 wide shot. So the order is:

- Initial medium shot (0.0): person at table, hands on fabric.

- Then close-up (1.4,2.5): hands working on fabric with tool.

- Then 3.6: person adjusts fabric (maybe moving it).

- Then 4.7: back to medium shot.

So caption should be chronological:

A person in a blue shirt sits at a table with an iron and a maroon towel, working on a gray fabric patch. The camera zooms in top-down to show the person’s hands using a small tool to smooth the fabric, with a purple stuffed toy and books in the background. The hands continue manipulating the fabric, then the person adjusts its position on the towel, and the camera pulls back to a medium shot of the person at the table.

Check rules:

a) Motion: working, zooming in, adjusting, pulling back.

b) Appearance: blue shirt, gray fabric, purple toy, books (but background minimal), hands.

c) Spatial: hands on fabric on towel, toy to the left (maybe).

d) Camera: starts medium, zooms to top-down close-up, then pulls back.

e) Background: minimal, mentioned only as needed (books, toy in background for context).

f) No text, names.

Let me make it concise.

<caption_output>A person in a blue shirt works at a

The person's hands and a knife are moving to unwrap and cut a piece of bread. The motion is driven by the person's explicit actions.

The background (bookshelf, stuffed toy, window blinds) is static and shows no uniform shifting. There is no dominant fire, water, smoke, or wind motion.


A hand with painted nails applies a light-colored rectangular patch to a person’s side, who is wearing blue shorts. The hand presses the patch firmly onto the skin. A beige couch is visible in the background, and the camera remains in a close-up perspective throughout.

A hand with blue-painted nails moves a rectangular adhesive tape across the abdomen of a person. The tape adheres to the skin and is repositioned multiple times.

The background (beige couch) remains static throughout; no environmental elements like fire, water, or wind are present.


A person's hands, one wearing a bracelet, cut a yellow object on a wooden cutting board in front of a cluttered kitchen counter. The hands move the knife to slice the object, adjusting position as they work. The background includes a sink, colorful items, and a living area with couches. The camera maintains a circular, top-down perspective with slight movement.

Discrete solid objects (human hands, a knife, and food items on the cutting board) are moving. The hands are actively cutting and arranging food, indicating explicit physical interactions.

The background includes a kitchen countertop, sink, and cabinets. There is no significant shifting of static background elements (walls, ground) or fluid/environmental motion (fire, water, smoke, wind).


A person wearing a blue short-sleeve shirt sits while holding a red watermelon slice, repeatedly bringing it to their mouth to take bites and chew. The watermelon is held in front of them, with the person's hands visible as they manipulate the slice. The camera maintains a close-up perspective with slight movement throughout.

The video opens with a top-down view of a person in a sleeveless top and dark pants on a black yoga mat, bending forward with arms extended. The individual then raises one arm while seated. The scene transitions to an outdoor grassy area where three people in athletic wear (including one in a white top) sit on purple yoga mats, stretching upward with arms raised. The camera shifts from top-down to a ground-level perspective of the group.

Multiple solid human subjects are performing yoga poses, moving their limbs and bodies through deliberate physical actions (e.g., arm extensions, seated postures). These are discrete, trackable objects.

The background consists of static wooden flooring (indoor) and grass with scattered leaves (outdoor), with no dominant fluid or gaseous motion (e.g., fire, water, smoke, wind) observed. Background elements do not shift uniformly across the screen.


A person in a red shirt, cowboy hat, and blue jeans rides a brown horse. The horse moves forward from under a covered structure into an open dirt area, passing the structure toward a fenced field. The rider maintains a steady posture as the horse proceeds. The camera follows the motion with a slight pan, capturing the transition from shaded to sunlit terrain.

A person riding a horse moves consistently across the frame; the horse's locomotion is the primary solid-object movement.

No shifting background elements (trees, fence, ground remain stable), no fluid or environmental motion (fire, water, wind) observed.


A person wearing a white headwrap and white top has three beige circular patches on their forehead. They use their right hand, adorned with a ring, to gently press and smooth the patches across their face, starting from the forehead and moving toward the eyes. The camera maintains a steady close-up perspective focused on the face, with a plain background featuring a white wall and a mesh panel.

The person's hand is moving in controlled motions to apply makeup to the face, representing discrete solid-object motion (hand/finger movement due to muscle action).

A person wearing a white top, black pants, and white shoes performs martial arts movements in a gravel courtyard. They begin with arms extended, step forward into a wide stance, extend an arm outward while rotating their body, shift weight to one leg, and gradually return to a neutral posture. The background includes trees and a metal fence, captured from a static camera angle.

The person (wearing white top and black pants) is moving, performing discrete martial arts stances with clear locomotion (stepping, arm extensions, posture changes). This solid object's motion is explicitly driven by physical forces.

The background elements (trees, fence, mountains) remain stationary with no uniform shifting, and there is no fluid/environmental motion (fire, water, smoke, wind) dominating the scene. The environment appears calm and static.


A person wearing dark clothing and a hat bends over on a snow-covered wooden dock, facing a medium-sized brown dog standing beside them at the water's edge. The dog remains stationary while the person maintains a bent posture, possibly interacting with the dog. The dock extends into a partially frozen pond, with snow-covered ground and trees in the background. The camera remains stationary throughout, capturing the scene from a fixed angle.

A person and a dog on a dock exhibit subtle movement (e.g., the dog shifting position, person possibly adjusting stance), indicating discrete, solid objects in motion due to their own locomotion.

Background elements (trees, snowy shore) show no significant shifting. The water is calm with no visible waves or flow, ruling out dominant fluid motion.


A woman with long dark hair, wearing a black crop top and black pants, dances energetically in a street at night, moving her arms and body in rhythmic motions while twisting and turning. She faces different directions, surrounded by a crowd of people—some standing, others sitting on the curb—observing her. The handheld camera, slightly shaky, follows her closely, capturing her dynamic movements against an urban backdrop with minimal background details.

The belly dancer is the main moving object, performing rhythmic movements (hip swaying, arm gestures, and fan motion). Other people in the background are mostly stationary or making minimal movements.

The background (crowd and street) is stable with no dominant fluid or environmental motion (e.g., fire, water, wind). The audience is mostly stationary, with only minor individual movements.


A hand uses a knife to spread a yellow butter across the top surface of a square white bread slice resting on a wooden cutting board. The knife moves horizontally across the bread, spreading the butter evenly. The camera maintains a top-down perspective throughout, capturing the motion of the hand and knife against the light brown board.

Background (brick walls and curtain) is static with no shifting. No fluid or environmental motions (fire, water, wind) observed.


RAW CAPTION: Got it, let's break this down. First, I need to look at the video frames provided. The main subjects are three people sitting outside a building. Let's check their actions chronologically.

In the first frame, there's a person in a red top and denim shorts on the right, another person in a red top and dark shorts, and a person in a dark shirt. Wait, the first frame: the person in red is on the left (sitting on a chair), then someone in dark shirt, then a blonde in red top. Wait, looking at the frames:

[0.0] Three people sitting on chairs outside. Left: woman in red top, dark shorts, sitting on chair. Middle: man in dark shirt. Right: woman in red sleeveless top, denim shorts. On the table between them, there's a plate with food. Left side of frame: a table with cups, bottles, green items.

[0.3] The first frame shows the people. Then in [0.6], the woman on the left (red top) is bringing her hand to her mouth, maybe eating. Then [0.9], she's still eating. [1.2], she's finishing eating, then [1.5], she's looking to the side. Wait, the video is from 0 to 5 seconds, so the actions happen over time.

Wait, the task is to describe in chronological order. So starting from the beginning:

At 0.0 seconds, three people are seated on outdoor chairs: a woman in red top and dark shorts (left), a man in dark shirt (middle), and a woman in red sleeveless top and denim shorts (right). The woman on the left is eating from a plate on a small table between them.

Then, as time progresses (0.3s to 1.2s), the woman in red top (left) continues eating, then she lowers her hand, possibly finishing. The woman on the right (red top, denim shorts) is holding a cup, looking towards the left. The man in the middle is sitting still.

Wait, let's check the actions:

- Frame 0.0: All seated. Left woman eating, middle man, right woman holding cup.

- Frame 0.3: Left woman still eating, middle man, right woman holding cup.

- Frame 0.6: Left woman brings hand to mouth (eating), middle man looking at her, right woman looking forward.

- Frame 0.9: Left woman lowers hand (after eating), middle man looks at her, right woman holds cup.

- Frame 1.2: Left woman looking to the left, middle man looks at her, right woman holds cup.

- Frame 1.5: Left woman looks to the left, middle man looks at her, right woman holds cup.

So the main motion is the woman on the left eating and then turning to look left, while the others sit.

Now, appearance: number of people—three. Left: woman in red top (sleeveless?), dark shorts. Middle: man in dark shirt. Right: woman in red sleeveless top, denim shorts. The table has a plate, cups, etc.

Spatial relationships: The left woman is seated on a chair, to the left of the man, who is to the left of the right woman. The table is between them.

Background: The building has windows with curtains, a patio area.

Camera: It seems stationary, as there's no mention of movement. The camera angle is a medium shot, front-facing.

Now, following the rules:

a) Focus on motion and behavior chronologically.

b) Describe appearance and number.

c) Spatial relationships.

d) Conclude with camera perspective and movement.

e) Background minimal.

f) No text, names, etc.

So let's structure it:

Three people sit on outdoor chairs: a woman in a red sleeveless top and denim shorts (right), a man in a dark shirt (middle), and a woman in a red top and dark shorts (left). Initially, the left woman eats from a plate on a small table between them, while the right woman holds a cup. The left woman continues eating, then lowers her hand and turns to look left, with the man observing. The right woman remains seated holding her cup. The camera is stationary, capturing a front view of the scene.

Wait, need to make it concise, chronological.

Check for chronological order:

- At start, left woman eats, others sit.

- Then, left woman finishes eating, turns to look left.

- The others stay seated.

Now, the caption:

Three people sit outside a building: a woman in a red sleeveless top and denim shorts (right), a man in a dark shirt (middle), and a woman in a red top and dark shorts (left).

Three individuals are seated on a porch. They exhibit discrete movements: adjusting positions, touching, and gesturing. These are solid objects moving due to their own actions.

The background (building walls, railing) is static with no shifting or fluid motion. There are no environmental elements like fire, water, or smoke. No wind effects observed on vegetation or objects.


A person wearing a plaid skirt and light top sits on a stool, plucking the strings of a tall wooden harp while positioned in front of a music stand. The individual’s hands move rhythmically across the harp’s strings, with a water bottle placed on the ground nearby. The scene remains static with no camera movement, set against a backdrop of trees and open ground.

The harpist (a solid person) moves their hands and upper body to pluck/strum the harp strings, exhibiting clear discrete locomotion and physical interaction with the instrument.

Background consists of static trees and ground with no visible fluid motion (fire, water, smoke) or significant wind-induced swaying; background elements remain uniformly fixed across frames.


RAW CAPTION: Got it, let's break this down. The video shows someone washing a pot in a sink. First, the person is holding the pot under running water. Then they tilt it to drain water, maybe rinse it. The pot is dark, maybe black or dark gray. The sink is stainless steel. Background has a dish rack with bottles, a blue dish soap bottle, and a pump soap dispenser. The camera is probably static, focused on the sink area. Let's put it in chronological order.

Start: Person holds dark pot in sink, water running. Then they tilt the pot to empty water, then maybe rinse inside. The movements are pouring out water, scrubbing (though not sure, but actions). Then the pot is placed on the counter maybe. Wait, the video starts with the pot in the sink, then they tilt it, drain, and then place it on the counter? Wait, the frames: [0.0] person holds pot under water, [1.4] tilting to drain, [2.5] maybe rinsing, [3.6] draining more, [4.7] the pot is empty, water in sink. So the main actions are pouring out water, rinsing.

Now, the caption needs to be concise, chronological. Describe the motion: A person holds a dark pot under running water in a stainless steel sink. They tilt the pot to drain water, then rinse the interior. The pot is emptied and placed on the counter. Background: dish rack, blue dish soap bottle, pump soap dispenser. Camera is fixed, top-down view? Wait, the video is from a fixed angle, likely above or side. The rules say mention camera perspective. Let's check the output format.

Focus on motion and behavior. So:

A person holds a dark-colored pot under running water in a stainless steel sink, tilting it to drain water and rinse its interior. The person then places the pot on the sink counter. In the background, a dish rack with bottles and a blue dish soap container are visible. The camera remains stationary, capturing the actions from a fixed angle.

Wait, need to be concise. Let's check the rules: chronological, motion, appearance, spatial, camera.

So:

A person holds a dark pot in a stainless steel sink, tilting it under running water to drain and rinse. They empty the pot into the sink, then set it down on the countertop. A blue dish soap bottle and a pump soap dispenser are visible on the sink edge. The camera maintains a static, overhead perspective.

Wait, the video starts with the pot in the sink (first frame shows person holding it), then tilting (so pouring water out), then placing on counter. So the sequence:

1. Person holds dark pot under water in sink.

2. Tilt to drain water.

3. Rinse interior (maybe with hands).

4. Place pot on counter.

So the caption should describe this order.

Let me draft:

A person holds a dark-colored pot under running water in a stainless steel sink, tilting it to drain water and rinse its interior. They then place the pot on the sink counter. In the background, a dish rack with bottles and a blue dish soap container are visible. The camera remains fixed, capturing the actions from a top-down angle.

Wait, check the rules: "conclude with camera perspective". So after describing the motion, mention camera.

Also, background descriptions minimal. So maybe just mention what's essential. The dish soap and pump soap are on the sink edge, maybe necessary for context but not essential. Let's see.

Another version:

A person rinses a dark pot in a stainless steel sink, tilting it to drain water and scrubbing its interior. The pot is then placed on the countertop. A blue dish soap bottle and a pump soap dispenser sit on the sink edge. The camera remains stationary, focusing on the sink area.

Check for conciseness. Let's make it shorter.

A person holds a dark pot under running water in a stainless steel sink, tilting it to drain and rinse. They place the pot on the counter. A blue dish soap bottle and pump soap dispenser are visible on the sink edge. The camera stays fixed, providing a top-down view.

Wait, the video's first frame shows the person holding the pot, then tilting to empty water (so draining), then rinsing, then placing on counter. So "tilting to drain water and rinse" covers the actions.

Now, check all rules:

a) Motion and behavior chronological: yes.

b) Appearance: dark pot, stainless steel sink, blue dish soap.

c) Spatial: pot in sink, dish soap on edge.

d) Camera: fixed, top-down? The video is likely a close-up of the sink, so maybe top-down or side view. The user says "camera perspective", so "fixed,

The person's hands and a black pot are moving. The hands are scrubbing the pot and moving it in the sink.

The background (counter, sink, cleaning products) is stationary. The water in the sink is part of the washing process but is not the dominant motion (it is driven by the person's actions and not ambient fluid motion like a waterfall).


A white ceramic mug with a handle sits on a speckled granite countertop filled with dark liquid. A hand enters from the top right, stirring the liquid with a metal spoon, lifting a portion of the liquid. The spoon is withdrawn, followed by a white pitcher pouring a light-colored liquid into the mug. The camera maintains a top-down perspective throughout, capturing the sequence without movement.

A hand and spoon interact with the coffee cup (stirring and scooping), and a milk container pours liquid into the cup. These are discrete solid objects moving due to human action.

The granite countertop background remains static with no uniform shifting, and there is no fire, smoke, or wind-driven fluid motion. Liquid pouring (coffee and milk) is a controlled action, not ambient environmental fluid dynamics.


A person wearing a purple shirt holds a black band, then retrieves a red cap and positions it against their chest. The camera maintains a close-up perspective with slight movement.

Hands manipulate discrete objects: a smartwatch (initially held), a red New York Yankees cap, and the purple fabric garment. The hands move these objects through physical adjustment.

The background consists of a static purple fabric with no shifting elements, fire, water, or wind present. No ambient environmental motion detected.


A green and red cloth moves in front of the camera, partially obscuring the view of a cluttered room with shelves and a window. The cloth shifts positions, covering and revealing the background before moving toward the camera again. The camera remains stationary with minimal movement.

The person (with green hair) is moving their head and body in front of the camera, causing partial obscuration of the background.

The background (shelves, window) is static and not shifting uniformly. There is no fire, water, smoke, or wind present.


A boy wearing a blue and yellow shirt with a green and red graphic manipulates a small red object at a table, opening it with both hands while seated. He briefly looks up before returning focus to the object, with the camera alternating between close-ups of his hands and a wider shot showing him at the table with a wooden bench in the background, concluding with a close-up of his hands on the red object.

Child manipulates a red solid object (likely a toy) with hands, showing discrete hand movements (opening/closing, twisting) and brief head movement toward the camera.

No shifting background; no fire, water, smoke, or wind. Background elements (wooden bench, pipes, window) remain static throughout the clip.


A person wearing a white shirt and dark shorts runs across a grassy field, then bends down to pick up an object from the ground before standing and walking toward the camera. The background includes distant trees and buildings, and the camera remains stationary throughout the sequence.

A person is moving: walking, running, and bending down (likely to pick up an object). The motion is due to their locomotion.

The background (trees, power lines, building) is static and does not shift. There is no significant environmental fluid motion (fire, water, wind) dominating the scene.


A group of women wearing black tops and dark pants with red accents dance energetically in front of a white lattice fence, moving in unison with raised arms and rhythmic steps; the camera pans left slightly with a minor shake, capturing their dynamic motion.

Multiple dancers (solid, distinct objects) move through coordinated locomotion: arm raises, stepping, and body swaying. Their motion is physically driven by intentional movement, clearly trackable with bounding boxes.

The background (trees, fence, structures) shows no uniform shifting or fluid motion. No fire, water, smoke, or significant wind-driven motion is present. Background elements remain largely stationary relative to the frame.


A black and tan dog sits near wooden cabinets and a sliding door. A hand enters from the right, offering a small object; the dog moves forward to interact with it, then lies down on the floor. The camera remains static throughout the sequence.

The dog undergoes discrete locomotion: sitting, lowering head (to interact with a treat), lying down, and shifting gaze. A human hand enters the frame to offer a treat (0.9s), then retracts. These are solid objects exhibiting explicit physical forces (voluntary movement, object interaction).

The background (wooden cabinets, sliding glass door, floor) remains static throughout the video. No fluid motion (fire, water, smoke) or environmental phenomena (wind, waves) are present. The scene exhibits fixed spatial relationships between background elements.


A person in a white lab coat and blue gloves sits at a laboratory bench, adjusting a microscope while looking through its eyepiece. They make slight movements with the focus knobs, positioned in front of a pink mat holding glassware and lab equipment. The background features a computer and a red cabinet. The camera remains static throughout.

A person (woman in lab coat/gloves) is manipulating equipment (likely a microscope) with discrete hand movements, showing intentional physical locomotion and interaction with solid objects.

Background elements (computer monitor, red cylinder, lab equipment, walls) remain static and show no shifting or fluid motion (no fire, water, smoke, or wind effects). Background is fixed and uniform, indicating no camera-induced motion.


A pair of hands manipulates a metallic bolt on a silver mechanical bracket, adjusting its position. The hands then shift to interact with adjacent components, revealing a bike's frame and a gear assembly. The camera pans slightly to the right, transitioning from a close-up of the hands to a wider view of the bike's mechanical structure. Background remains blurred and neutral, emphasizing the hands' actions on the machinery.

Discrete solid objects: hands and a tool (wrench) moving to manipulate a mechanical part. The motion is due to human force application.

No shifting background or fluid/environmental motion (fire, water, wind) observed. The background appears to be static metallic structure without uniform movement.


RAW CAPTION: Got it, let's break this down. First, the video shows a person interacting with a tree and a wooden structure. The person is wearing a dark jacket, blue jeans, and a cap. They have a red container. Let's look at the sequence:

Start: Person is climbing or moving around a tree. In frame 0, they're on the left side, reaching up. Then they move to the right, holding onto the tree and the wooden plank. The red container is on the ground initially? Wait, in frame 0, they have it. Wait, no—frame 0: person is near tree, holding something. Then frame 1: moving towards the tree, holding red container. Wait, need to check the frames. Let's see:

Frame 0: Person is on the left, leaning against tree, holding red container. Frame 1: they're moving towards the tree, still holding container. Frame 2: they're now on the right side, hand on the wooden plank attached to the tree, red container near the tree. Then frame 3: they're adjusting their position, hand on the plank. Frame 4: they step back, container on the ground? Wait, no, the sequence shows the person moving around the tree, handling the container and the plank.

So the main subject is a man (dark jacket, blue jeans, cap) with a red container. He moves from left to right around the tree, interacting with the wooden structure (maybe a fence or barrier) attached to the tree. He uses his hands to hold the structure, and the container is carried. Then he steps back, container still in hand? Wait, the frames show him moving, then in frame 3 he's holding the container near the tree, then frame 4 he's stepping away, container still there? Wait, no, maybe the container is on the ground. Let me check again.

Wait, the video: the person starts on the left, holding the red container. Then moves towards the tree, placing the container near the tree. Then reaches up to the wooden structure (like a plank) attached to the tree. Then pulls the container up, then steps back. So chronological:

- Man (dark jacket, blue jeans, cap) carries red container to tree, places it near base.
- Then grasps wooden plank attached to tree, pulls container towards tree.
- Then steps back, holding container and plank.

Wait, maybe better to track each action:

Start: Person is on left side of tree, holding red container. Moves right, approaching tree. While moving, reaches out to the wooden plank (attached to tree). Then holds the plank, pulls the container up. Then steps back, container now near the tree.

Need to make it concise. Mention appearance: man in dark top, blue jeans, cap. The red container. Wooden structure (plank) attached to tree.

Spatial: Man starts left of tree, moves to right, interacts with tree and plank.

Camera: Looks like a handheld camera, slight shake, maybe following the man's movement.

Background: Outdoor, garden-like with plants and dirt, but minimal as per rules.

So putting it all together chronologically:

A man wearing a dark jacket, blue jeans, and a cap carries a red container toward a tree with a wooden plank attached to its trunk. He positions himself to the right of the tree, uses his right hand to grasp the plank, and maneuvers the container near the base of the tree. He then steps back, holding the container and plank, while the camera remains slightly shaky and follows his movement.

Check rules: motion and behavior chronological, appearance (color, size, orientation—man in dark jacket, etc.), spatial (to the right of tree), conclude camera perspective (slight shake, follows movement). Background minimal.

Let me refine:

A man in a dark jacket, blue jeans, and a cap carries a red container toward a tree with a wooden plank attached to its trunk. He moves to the right of the tree, grasps the plank with his right hand, and maneuvers the container near the tree’s base. After adjusting his position, he steps back, holding the container and plank. The camera remains slightly shaky and tracks his movement.

Wait, the red container is red, so mention color. Also, "wooden plank" is part of the structure.

Yes. Let's check all rules:

a) Chronological motion: starts with carrying container, then moving to tree, grasping plank, maneuvering container, stepping back.

b) Appearance: man (dark jacket, blue jeans, cap), red container.

c) Spatial: tree with plank, man moves to right of tree, container near base.

d) Camera: slightly shaky, follows movement.

e) Background minimal (only necessary parts mentioned, like garden but not too much).

f) No text, names, stylist

A person (solid object) is moving via locomotion and arm gestures, interacting with a tree and a red box. The motion is due to explicit physical forces (e.g., stepping, reaching, lifting).

The background (trees, hills, and ground elements) remains stable with no significant fluid or wind-driven motion. No fire, water, or smoke is present, so ambient environmental motion is not dominant.


A woman with long brown hair, wearing a dark top, blue jeans, and brown shoes stands on a stage. She adjusts her pants, then raises her right hand to her mouth while looking around. Behind her, two individuals in red shirts observe from the background. The camera remains stationary throughout, capturing the scene from a fixed angle.

A single person (woman) is the discrete object moving: exhibiting controlled gestures and body shifts while speaking into a microphone. No other moving solid objects are present.

The background (stage backdrop, equipment, and structural elements) remains static throughout the clip with no fluid motion (fire, water, smoke) or wind effects observed. No ambient environmental motion detected.


A person in a pink shirt and dark hair, wearing no pants, performs a backward flip mid-air. Initially upside down with arms extended, they rotate through the motion, hands moving forward as their body twists. The camera tracks the subject's trajectory against a forested backdrop.

A person in a red shirt is moving through the scene, transitioning from an inverted position to a downward fall. The motion appears to be due to gravitational force (free fall/dive), with the person’s limbs and body position changing as they descend.

The background consists of static trees and misty fog. The fog shows minimal movement, but no dominant fluid or wind-driven motion (fire, water, smoke, wind) dominates the scene. Static background elements (trees) do not shift uniformly.


A child wearing a purple swim cap and yellow goggles swims toward the pool’s edge, surfacing and waving with their right hand as they approach the concrete deck. Another person floats near the pool’s right side, while others are visible in the background near the far end. The camera remains stationary, capturing the scene from a fixed position along the pool’s edge.

Swimmers are actively moving through the water; one swimmer emerges at the edge and waves at the camera.

The background elements (walls, railings, pool deck) are static. Water in the pool shows minor ripples from swimming, but this is secondary to the swimmer motion and not the dominant motion.


A man in a yellow shirt and beige shorts stands on a golf green, addressing the ball with a golf club. He bends forward, swings the club, and strikes the ball, sending it rolling across the grass. In the background, another person is visible further down the green. The camera remains stationary, capturing the scene from a fixed perspective.

A golfer (solid object) performs a swing motion and strikes a golf ball (solid object). The ball moves through the air after impact, exhibiting clear trajectory motion due to collision with the club.

The background (trees and grass) shows minimal wind-induced swaying of trees, but no fire, water, smoke, or significant environmental fluid motion. Tree movement is subtle and not dominant.


The video opens with an animated brown pig with antlers on a bridge in a green field, chasing frogs. It then cuts to a woman with curly hair and gold earrings sitting on a green couch, reading a book and flipping through its pages. The scene transitions to a close-up of the pig as text appears. Camera alternates between animation and live-action, showing the pig’s actions and the woman reading.

The child is turning the pages of a book, causing the illustrations to change. The child's hand and the book are discrete solid objects in motion due to physical action.

The background (green wall with decorations) is static and does not shift. There are no fluid or environmental motions (fire, water, wind) dominant.


A muscular man in a black sleeveless shirt and cap stands in a boxing ring, adjusting his waistband. Another individual in a gray shirt approaches from the side, placing hands on the first man's shoulders. The two interact closely, with the second person moving around the first man's torso. The camera remains stationary, capturing the interaction from a frontal perspective within the ring.

Two discrete objects (a large man and a woman) moving: the woman walks into frame and stops facing the man; the man adjusts his belt and shifts position slightly.

Background elements (boxing ring, banners, clock) are stable with no shifting or fluid motion. No fire, water, smoke, or wind present.


A person wearing a dark top, red pants, and a hat stands on a frozen expanse, walking slowly from right to left across the ice. The camera remains stationary, capturing the individual’s movement against a distant brown hillside background.

A single person is moving on the snow. The motion is subtle and likely due to walking.

The background (wooded area) is static with no signs of fluid motion (fire, water, smoke, wind) or uniform shifting. The environment is a snowy field with static trees in the distance.


Two hands hold a white smartphone, with the left hand typing on the keyboard and the right hand sending messages, causing blue message bubbles to appear on the screen. The phone remains centered in front of the hands against a window background. The camera maintains a steady close-up perspective throughout.

Hands and smartphone are moving; discrete solid objects with explicit motion from typing (fingers pressing keys on the phone). Motion is localized to the hands/phone, with no background blur or uniform shifting.

The background (window with horizontal bars and wall) is static and shows no shifting or environmental motion (fire, water, wind). The background elements remain fixed relative to the scene.


RAW CAPTION: Got it, let's tackle this. First, the video shows a group of people riding bicycles on a dirt road. The main subjects are the cyclists. Let's check the order. The first part: a person on a bike is ahead, then more cyclists behind. Wait, the video starts with a person on a bike in the middle distance, maybe leading. Then as the video progresses, there are more cyclists in front? Wait, the first frame has a person in front, then the next frames show more people. Wait, the camera is moving forward, so it's a first-person perspective of someone riding, following the cyclists.

Let's break down the chronological order. The video starts with a cyclist ahead, then more cyclists come into view as the camera moves. Wait, the first frame: a person on a bike, then a few more cyclists in front. Wait, in the first frame, the person is slightly to the right, then in subsequent frames, more cyclists are visible. Wait, the video is from a first-person perspective (like someone riding a bike), so the camera is moving forward along the dirt path.

Main subjects: multiple cyclists. Let's count. First frame: one cyclist ahead, then in the next frames, more. Wait, the video shows a group. Let's say initially, a cyclist is in front, then as the camera moves forward, more cyclists appear to the left or ahead.

Appearance: cyclists are on bikes, wearing dark clothing maybe? But the rules say briefly describe appearance and number. So "multiple cyclists on bicycles, wearing dark attire" (but maybe not necessary to say color, but the problem says color, size, orientation—so maybe "several cyclists on bicycles" without color unless obvious. Wait, the rules say "briefly describe their appearance and number (color, size, orientation)". So we can say "multiple cyclists on bicycles, wearing dark clothing" but maybe not. Wait, the background: sunset, dirt road, trees. But background should be minimal.

Chronological order: The video starts with a cyclist ahead on a dirt road. As the camera moves forward, more cyclists become visible in front. The cyclists are moving forward along the road. The camera is from a first-person perspective, moving forward with the cyclists, so the camera is following the group, possibly a slight movement forward.

Wait, the first frame shows a person on a bike in the distance, then in subsequent frames, more people on bikes appear ahead. Wait, no—actually, the first frame has a person on a bike, then the next frames show more people. Wait, looking at the frames:

[0.0] shows a person on a bike, with trees on the left, open field on the right, sun low (sunset). [1.0] similar, but the person is slightly closer? Wait, no, the camera is moving. Wait, the perspective: the camera is likely mounted on a bike, so it's moving forward. So the main subjects are the cyclists ahead. Let's see:

Initial frame: one cyclist ahead, then as the video progresses, more cyclists come into view. Wait, maybe the group is moving forward, and the camera follows. So the first action: the camera is moving forward along a dirt path, with several cyclists ahead, moving in the same direction. The cyclists are on bicycles, appearing as small figures at first, then larger as they approach. Wait, but the video is short—0.3 to 5 seconds.

Wait, let's describe the motion. The camera starts by showing a cyclist ahead, then as it moves forward, more cyclists are visible in front. The cyclists are on bicycles, wearing dark clothing, moving forward along the dirt road. The camera is from a first-person perspective, moving steadily forward, following the group. The background has a dirt road, trees on the left, and a sunset sky.

Now, rules:

a) Focus on motion and behavior in chronological order. So the video starts with the camera moving forward, following cyclists on a dirt road. The cyclists are ahead, moving forward. As the camera moves, more cyclists become visible. Wait, but in the first frame, there's a person, then more in subsequent frames.

Wait, the first frame: person on bike, then next frames show more people. So the main subjects: several cyclists on bicycles, moving forward. The camera is moving forward with them.

b) Number: "multiple cyclists on bicycles". Appearance: "dark clothing" maybe. Orientation: moving forward.

c) Spatial relationships: cyclists are ahead of the camera, moving in the same direction. Maybe "several cyclists in front" as the camera moves.

d) Camera perspective: first-person (as if riding a bike), moving forward.

e) Background minimal: dirt road, trees to left, open field, sunset.

f) Exclude text, names.

A person in dark clothing dances in a room with a colorful circular mural on the wall. Seated individuals are visible to the left, while stacked chairs occupy the right side. The dancer lifts their right leg, steps forward, and turns, continuing to move rhythmically. The camera remains stationary with minimal shakiness, capturing the scene from a frontal perspective.

A man in a suit is the primary moving object, exhibiting locomotion (walking, turning, and stepping) due to his own physical forces. His motion is discrete, solid, and trackable with a bounding box.

The background (mural, room elements, and furniture) remains stationary throughout the video with no fluid or environmental motions (e.g., fire, water, wind). Static background elements like the wall and floor show no uniform shifting.


A person in a white chef's coat holds a yellow potato and uses a vegetable peeler to remove skin, with light brown peelings accumulating on a white tray. The individual's hands move rhythmically as they peel, transferring the skin to the tray; a green-handled peeler rests on the tray to the left, while whole potatoes sit in a separate tray to the right and peeled potatoes are visible in a clear container to the left. The camera maintains a top-down view before zooming in to focus on the peeling motion. Background elements are minimal, emphasizing the task.

The person's hands are actively peeling a potato, causing discrete motion of the potato and peel fragments on the tray.

No shifting background elements observed; no fluid/environmental motion (fire, water, wind) present in the scene.


A person in a black and white striped shirt lies with their head resting on a light blue pillow, their mouth moving slightly as they speak while their eyes remain directed toward the camera. Their shoulder is visible, positioned to the right of the frame. The camera maintains a close-up, static perspective throughout, capturing the individual against a dark background.

The person's face and head exhibit subtle movements (blinking, mouth opening/closing) indicating natural physiological motion.

Background (pillow and fabric) is static with no shifting or environmental effects. No fire, water, smoke, or wind observed.


A person wearing a red life vest maneuvers a large white inflatable boat in shallow water, initially adjusting the tilted vessel before stabilizing and moving it through the water. The camera remains static, observing the sequence from a fixed position with the water and distant land visible.

A person in a white boat is visible; the individual is moving within the boat, shifting position and interacting with the vessel, indicating solid-object locomotion due to physical actions.

The background shows a calm body of water with a distant horizon line; no significant fluid motion (e.g., crashing waves, billowing smoke) dominates the scene, and background elements remain stable without uniform shifting.


RAW CAPTION: Got it, let's tackle this. The video shows a kid in a red striped hoodie sprinkling something on a tray. First, the kid is holding a blue shaker, moving it over the tray. The tray has several pinkish-white items, maybe cookies or dough. Then the screen goes black, and a text bar says "Step 3: More sprinkles."

Need to focus on motion: kid is sprinkling, then the text. Describe the kid's action chronologically. Mention the hoodie color, the tray's contents. Spatial: kid is at the table, tray in front. Background minimal, just the table and maybe a room. Camera is static, top-down? Wait, the first frames show the kid from the front, then the text.

Wait, the rules: chronological paragraph. Start with the kid sprinkling. Then the transition to black with text.

So: A child in a red and black striped hoodie stands at a wooden table, holding a blue shaker above a dark tray with multiple small pink and white mounds. The child moves the shaker to sprinkle contents onto the mounds. The scene then cuts to black, displaying the text “Step 3: More sprinkles” on a gray bar.

Check rules: no text recognition? Wait, the text is part of the video, but the rule says "Exclude text recognition" Wait, no, the rule says "Exclude text recognition, named characters, or stylistic analysis." Wait, but the text is in the video. Wait, the problem says: "Exclude text recognition"—so do we mention the text? Wait, the instruction says: "Exclude text recognition, named characters, or stylistic analysis." So if the text is part of the video, do we include it? Wait, the user says: "You are an expert video captioner. Your task is to generate a concise, chronological paragraph describing the provided video."

But rule f: Exclude text recognition. Hmm. Wait, the example in the problem statement: the video has a text bar "Step 3: More sprinkles". But the rule says to exclude text recognition. Wait, but in the output, do we have to mention the text? Wait, the problem says: "Exclude text recognition". So maybe we don't mention the text. Wait, but the text is part of the video's content. Wait, but maybe the rule is to not describe the text (like "the text says X"). So in the caption, we don't mention the text. Wait, the video cuts to black with the text, so the action is the scene changing to black with the text. But according to rule f, "Exclude text recognition", so perhaps just describe the transition without mentioning the text. Wait, but the problem's example shows the text. Hmm.

Wait, the instructions say: "Exclude text recognition, named characters, or stylistic analysis." So "text recognition" means not to describe what the text says. So the presence of the text is part of the video, but we don't have to mention the words. Wait, but the scene has a text bar. So the caption should note that the screen goes black with a text bar, but not what the text says. Wait, but the rule says to exclude text recognition, so maybe we just say "a text bar appears" but not the text.

Wait, let's read rule f again: "Exclude text recognition, named characters, or stylistic analysis." So text recognition is when you describe the text content (like "Step 3: More sprinkles"). So we should not mention the text's content. But the scene has a text bar, so the caption needs to indicate that a text bar is shown, but not what it says.

Wait, but the problem says in the example: the video has the text. So the caption should include that there's a transition to black with a text bar, but since we can't recognize the text, we just say "a text bar appears".

Wait, the initial frames: child sprinkling. Then frame 5: black screen with gray bar. So the sequence is: child sprinkling, then screen cuts to black with a gray bar (text bar). So the caption should mention the transition.

So structure: A child in a red and black striped hoodie stands at a table, sprinkling contents from a blue shaker onto a tray of small pink and white mounds. The child moves the shaker in a downward motion. The scene then transitions to a black screen with a gray bar appearing at the center.

But check the rules: b) mention appearance and number. The child's hoodie is red striped (maybe black stripes). The tray has multiple mounds (color: pink and white). Spatial: child is at the table, tray in front.

Rule d: camera perspective. The video is shot from a fixed angle, probably

The child's hand and the spray bottle are moving as the child sprays the food on the tray.

The background (pink wall and table) is static with no shifting. There is no fire, water, smoke, or wind.


A person with bright pink hair and a black top holds a lit lighter near their mouth while manipulating a small object, then raises the lighter to display it. A blue chair is visible to the right in the background. The camera maintains a slightly shaky close-up perspective throughout.

The person is moving a lit candle (discrete object) with their hand, showing deliberate motion to adjust its position.

The background (wall and chair) is mostly static; no uniform shifting. The candle flame is present but not dominant motion.


A woman in a yellow sports top and shorts, wearing white socks and with long hair tied back, performs a barbell squat in a gym. She lowers the barbell from shoulder height to waist level while bending her knees, then rises back up. The gym background includes various equipment and other individuals working out. The camera remains stationary with minor vibration.

The woman and barbell are solid objects moving due to explicit physical forces (lifting motion), with clear bounding box tracking of the barbell's vertical displacement.

The gym walls and equipment are stationary; no shifting backgrounds or fluid/environmental motion (fire, water, wind) observed.


A person wearing a blue jacket and light green pants adjusts equipment on a red tractor while seated behind it, with a trailer holding green plants to their left and a red box to their right. The tractor moves forward slightly, kicking up dirt from the ground, as the person remains focused on their task. The camera maintains a handheld perspective with slight shake, capturing the motion from a side angle.

A person operating a tractor, with the tractor's wheels rotating and the vehicle moving forward across the ground.

Background elements (ground, tree) remain consistent and show no uniform shifting; no fire, water, or wind effects observed.


A man wearing a dark shirt, dark shorts, white socks, and a light cap walks across a street holding a hockey stick with a red puck. He moves forward toward a red goal net positioned ahead of him, swings the stick, and shoots the puck. The camera pans right to follow his motion, with houses and parked cars visible in the background.

A person actively moving along a street while using a long-handled tool (broom) to manipulate a small object on the ground; both the person and the tool exhibit discrete locomotion.

Background elements (houses, trees, parked cars) remain stationary and show no significant fluid/environmental motion (fire, water, smoke, wind). Tree swaying is minimal and not dominant.


A man in a black shirt and white pants is seated, playing a silver clarinet with his fingers moving across the instrument's keys. He is positioned in front of a fireplace adorned with decorative vases. The camera maintains a steady medium shot throughout the sequence.

The man (discrete solid object) exhibits controlled motion: finger movements on the clarinet keys and subtle head/mouth adjustments while playing. The clarinet itself remains relatively stationary, with motion confined to the player's hands and breath.

The background (fireplace mantel, jars, wall) remains static with no shifting, fluid motion, or environmental disturbances (no fire, water, smoke, or wind).


A person in a teal shirt crouches on the ground, then the camera shifts to focus on two individuals— one with white hair and another wearing blue shorts—positioning a wooden tool into the open mouth of a large, scaly crocodile lying on earthy ground. The hands adjust the tool while the crocodile remains motionless, with the camera maintaining close-up shots and slight shifts to capture the interaction.

Two individuals (teal-shirted person and another) interact with a wooden object featuring bone-like structures; hands manipulate the object through physical contact.

No shifting background elements (dirt, leaves remain static). No fire, water, or wind-driven environmental motion detected.


A person in a bright yellow jacket and black pants skates forward across the ice rink with arms extended, passing a central blue circle. Other skaters, including individuals in black and orange clothing, move through the rink in various directions. The camera remains stationary, capturing the dynamic flow of skaters across the ice.

Multiple skaters (people) are moving on the ice in various directions due to their own locomotion.

No shifting background or fluid motion; the ice rink environment has static structural elements (ceiling, walls) and the ice surface is stationary.


A dark, scaly alligator lies on sandy ground with its mouth open, facing left. The camera zooms in closely on the alligator’s head, showcasing its teeth and textured skin. A person in a dark shirt crouches to the left of the alligator, raising an arm toward its head. The camera shifts to frame the interaction, maintaining focus on the alligator and the person’s arm. Background is sparse sand and concrete. Camera movement includes a zoom-in and slight pan to the left.

An alligator moves slightly on the sand (opening its mouth, shifting position), and a human hand enters the frame to interact with the alligator. These are discrete solid objects moving due to physical forces (alligator's locomotion, hand's intentional motion).

The sandy ground background remains stable throughout the video, with no shifting or fluid motion (no fire, water, smoke, or wind). Background elements are static, indicating no dominant ambient environmental motion.


A young child wearing a red, white, and blue striped shirt sits at a table, lifting a spoon from a green bowl to their mouth. The child repeatedly scoops food from the bowl, bringing the spoon to their mouth each time, with a laptop visible in the background. The camera remains in a close-up position with a slight shake, capturing the child's eating motion from a frontal perspective.

The child is moving their head and arms while eating, with the fork being manipulated to bring food to the mouth.

The background (table and objects) remains static with no shifting or fluid motion. No fire, water, smoke, or wind is observed.


A person wearing a black shirt and blue shorts holds a black power tool with a coiled cord, then bends down while a small gray and white dog stands on a concrete path near grass, looking toward the person. The camera pans upward to focus on the dog and shifts to capture the person’s movement, with minimal background details of the concrete path and grass visible.

A dog walks away from the camera and a person adjusts the leaf blower, bending down.

No uniform background shifting; no fire, water, or smoke. Background elements (concrete, grass) remain stable.


A man in a dark vest and light shirt interacts with a woman in a white shirt near a dimly lit bar counter; he gestures toward her while she holds a drink, then adjusts his vest as they shift positions. The woman remains near the counter, gesturing with her hand, while the man moves slightly left before stepping away. The camera pans left with a slight shake, capturing their movements against a red-lit background with blurred glassware and bottles.

Discrete solid objects (people) are moving: a woman raises her drink and sways her body, while a man (bartender) gestures with his arms and shifts position. These motions are locomotive and interpersonal interactions.

The background elements (bar shelves, bottles, wall fixtures) remain relatively static with no uniform shifting or fluid motion. No fire, water, smoke, or wind effects are present.


A young child in a black shirt, pink skirt, and black leggings sits cross-legged on a black mat. She stands, turns to the right, and walks away from the camera across the gym floor. The camera remains stationary, capturing her motion from a front-facing angle.

A child (discrete solid object) moves from sitting to standing and then walks across the frame.

No fluid or environmental motion (fire, water, wind). Background (white wall, gym equipment, black mat) is static and not shifting uniformly.


A person in a striped shirt holds a large yellow plush toy, moving it upward and then bringing it close to their face while standing amidst a crowd. The camera remains handheld and slightly shaky, tracking the toy's motion.

The man in a striped shirt is moving a yellow object (stuffed animal/costume) in a circular motion, and a child in pink is also moving.

The background (walls, banner) does not show uniform shifting; no fire, water, smoke, or wind is present.


RAW CAPTION: Got it, let's tackle this. The video shows a person playing an instrument. First, identify the main subject: a man seated, playing a bamboo flute-like instrument. The instrument has multiple pipes, so it's probably an organ or something similar. He's in a room with some background items, but focus on his actions. He's holding the instrument to his mouth, blowing, maybe moving his fingers on the pipes. The sequence: he's playing, maybe adjusting, but the frames are from 0 to 5 seconds, so he's continuously playing. The camera is stationary, right? No movement mentioned. Background has some items, but minimal. So chronological: the man sits, plays the instrument with bamboo pipes, fingers moving over the pipes, mouth on the mouthpiece. Spatial: he's behind the instrument, maybe the instrument is in front of him. Camera is fixed, top-down? No, the angle seems like a medium shot. Wait, the output format needs concise paragraph. Let's structure: A man with short dark hair, wearing a dark shirt, sits at a table with multiple bamboo pipe instruments. He holds a flute-like instrument to his mouth, blowing and moving his fingers over the pipes. The background includes a wall with framed items and colorful decorations, but keep minimal. Camera is static, slight shake? The problem says "slight shake" if present, but in the frames, maybe no movement. Wait, the user says "DO NOT include any reasoning in the caption tags." So need to stick to the rules. Let's check the rules again. a) Focus on motion and behavior chronologically. So the man is playing the instrument over time (0-5s). b) Appearance: short dark hair, dark shirt. c) Spatial: behind the table with instruments. d) Camera: static (no movement mentioned in the video description). e) Background minimal. f) Exclude text recognition, etc. So the caption: A man with short dark hair and a dark shirt sits at a table, playing a bamboo flute instrument by blowing into it and moving his fingers over the pipes. The instrument has multiple bamboo pipes extending upward. He remains seated, focused on playing, with no significant camera movement. Background includes a wall with framed pictures and decorative items but is not the focus. Wait, need to be concise. Let's make it a paragraph. "A man with short dark hair and a dark shirt sits behind a table, playing a bamboo pipe instrument by blowing into its mouthpiece and moving his fingers across the pipes. The instrument features multiple vertical bamboo pipes. He remains seated, focused on playing, with minimal hand movement over the pipes. The camera remains stationary throughout, capturing the man from a frontal angle with no significant movement or shake." Wait, but the rules say "concise". Let's trim. "A man with short dark hair and a dark shirt plays a bamboo pipe instrument at a table, blowing into the mouthpiece and moving his fingers over the pipes. The instrument has multiple vertical bamboo pipes. He remains seated, focused on playing, with no notable camera movement or background changes." But need to check if "vertical" is necessary. The video shows the pipes are arranged vertically, so maybe "multiple vertical bamboo pipes". Also, the camera perspective: the video shows him from a medium shot, probably frontal. The problem says "conclude with camera perspective and movement". So the camera is static (no movement), frontal angle. Let's structure:

In the video, a man with short dark hair and a dark shirt is seated behind a table, playing a bamboo pipe instrument. He holds the instrument to his mouth, blowing air while moving his fingers across the vertical bamboo pipes. The instrument is positioned in front of him, with other similar instruments visible on the table. The man remains focused on playing throughout the sequence, with no significant hand or body movement. The camera maintains a static frontal view with no noticeable movement or shake.

But check for conciseness. Let's shorten:

A man with short dark hair and a dark shirt sits at a table, playing a bamboo pipe instrument by blowing into it and moving his fingers over the vertical pipes. He remains seated, focused on playing, with no significant camera movement. The background includes a wall with framed items but is not the focus.

Wait, but the rules say "minimal background description". So maybe skip the background. Let's see the example. The user's example output format is a paragraph. Let's try to make it as concise as possible.

A man with short dark hair and a dark shirt plays a bamboo pipe instrument at a table, blowing into the mouthpiece and moving his fingers across the vertical bamboo pipes. He remains seated and focused throughout the sequence, with no camera movement.

<caption_output>A man with short dark hair and a dark shirt sits at a table, playing a bamboo pipe instrument by blowing into the mouthpiece

A person is actively playing an instrument, with visible motion in their hands and mouth due to instrumental interaction.

Background elements (walls, decorations, bamboo pipes) show no shifting or fluid motion. No fire, water, or smoke present.


A person in a red and black checkered shirt stirs a light brown crumbly mixture with two forks in a white plate, positioned to the left of a white plate with yellow batter and a plate of white flour. The scene transitions to a glass dish containing multiple golden-brown breaded chicken pieces arranged on a dark surface. The camera remains static after the initial close-up of the mixing process.

Discrete objects include the person's hands stirring batter and moving a plate of fried food. The hands exhibit controlled motion while transferring food between plates.

No shifting background elements observed; static kitchen counter and plates remain consistent. No fire, water, smoke, or wind-driven environmental motion present.


A person in dark clothing and purple gloves adjusts their black shoes while seated on a chair; a second individual in blue medical scrubs, face shield, and light blue shoes stands to the right. The camera pans outward, revealing the seated person’s full posture, the standing individual holding a small object, a red waste bin, a hand sanitizer dispenser, and a table with medical supplies in the background. The scene remains static with no significant movement beyond the initial adjustment of the shoes and the camera’s transition to a wider view.

A seated person (dark clothing) performs deliberate motion: hands adjust shoes (0.0-3.2s), then feet/legs move to stand and sit (3.3-5.0s). A standing person (blue scrubs) remains stationary throughout. Motion is intentional locomotion of solid objects.

Static white walls and furniture (chair, table, IV stand) remain fixed in both segments. No shifting background elements observed. No fire, water, smoke, or wind present.


RAW CAPTION: Got it, let's tackle this. The video starts with a top-down view of a pan on a blue stovetop. A hand is stirring a mixture of eggs, tomatoes, and maybe cheese. Then, coriander is added—wait, but the rules say exclude text recognition, so the "CORIANDER" text is out. So in the sequence, the hand adds fresh green coriander leaves to the pan. Then the hand moves to a white plate, maybe to serve? Wait, step 5: "a hand holding a yellow plate" no, wait, the fifth frame is "a hand holding a yellow object"—wait, the frames: [0.0] pan with stirring, [1.4] stirring more, [2.5] adding coriander (but text "CORIANDER" is there, but we ignore text), then [4.7] the scene changes to a hand holding a yellow plate (maybe a serving plate) near the white plate and some foil. Wait, no, the video steps: first part is stirring in pan, then adding coriander, then the scene shifts to a hand holding a yellow plate over a white plate. Wait, the user says "chronological paragraph describing the provided video".

Let's break down each frame:

- Frame 0: Top-down, pan on blue stovetop. A hand stirs a colorful mixture (eggs, tomatoes, maybe peppers) in the pan. The pan is silver, stovetop blue, background dark countertop with cilantro and lemon half.

- Frame 1-2: Same pan, stirring continues. The mixture is being mixed.

- Frame 3: Hand adds fresh green coriander leaves into the pan. The text "CORIANDER" is on screen, but we ignore text. So the hand adds coriander.

- Frame 4: Hand still stirring, now with coriander mixed in.

- Frame 5: Scene changes to a hand holding a yellow plate (or maybe a lemon half? Wait, the text says "a hand holding a yellow object" in frame 5). Wait, the description says: [5.0] a hand holding a yellow plate over a white plate. Wait, the user's input for frame 5 is "a hand holding a yellow plate" — but no, the user's input for the fifth frame (which is the last one) is: "a hand holding a yellow plate" (but in the input, the fifth frame is "a hand holding a yellow object" — wait, the input shows:

"4.7 seconds] You are an expert... [but wait, the user's input shows the frames as:

[0.0] pan with stirring

[1.4] stirring

[2.5] adding coriander (with text)

[3.6] stirring after adding coriander

[4.7] hand holding a yellow plate over a white plate

So step by step:

- At the beginning, a hand stirs a mixture of vegetables and eggs in a pan on a blue stovetop.

- Then, the hand adds green coriander leaves into the pan.

- Next, the hand continues to stir the mixture, incorporating the coriander.

- Finally, the scene shifts to a hand holding a yellow plate near a white plate, possibly preparing to plate the food.

Need to describe in chronological order. Focus on motions: stirring, adding ingredients, shifting to serving.

Background: dark countertop, but minimal description. Spatial relationships: pan on blue stovetop, hand in front of pan, then moving to yellow plate over white plate.

Camera perspective: top-down throughout, no movement mentioned (since it's top-down, and no pan or shake).

Check rules:

a) Motion: stirring, adding coriander, holding plates.

b) Appearance: hand (color? not specified, but hand), pan (silver), stovetop (blue), coriander (green), yellow plate.

c) Spatial: hand in front of pan, then yellow plate over white plate.

d) Camera: top-down.

e) Background minimal: dark countertop, but not essential for motion, so maybe mention "dark countertop" but keep minimal.

f) Exclude text: "CORIANDER" is text, so don't mention. Names: no named characters.

g) No reasoning.

So putting it together:

A hand stirs a colorful mixture of eggs, tomatoes, and other ingredients in a silver pan placed on a blue stovetop. The hand then adds fresh green coriander leaves to the pan, continues stirring to incorporate the herb, and finally moves to hold a yellow plate over a white serving plate.

Wait, check the frames: the last frame (4.7s

Hand moves wooden spoon to stir ingredients in pan; adds fresh coriander leaves; places toasted bread slice onto plate. All motions are discrete solid-object interactions (stirring, adding herbs, placing food).

No shifting background elements (countertop, blue cutting board, herbs, lemon) detected; no fire, water, smoke, or wind motion observed. Background remains static throughout cooking segment.


The video begins with a black screen, then a person wearing a green top and a long skirt with brown and beige panels stands on a wooden stage marked by white lines, holding two glowing poi (one green, one blue). The person moves the poi in a rhythmic pattern, crossing them in front of their body and bringing them together. The camera remains static, capturing the person from the front against a dark background with minimal visible elements.

A person manipulates glowing poi balls via hand movements, causing the balls to move in circular/figure-eight patterns through physical interaction (twirling, tossing).

The stage backdrop and floor lines remain stationary; no fluid/environmental motion (fire, water, wind) is observed.


A person in a light gray hoodie lifts a large black tire, moving it horizontally toward a red mechanical device with metallic poles. They position the tire onto the device, with the camera following the motion closely, shifting to a close-up view of the tire’s circular shape as it is secured in place. The person’s gloved hands guide the tire during placement, while the background remains minimally visible.

A person (wearing white shirt and dark pants) is moving a tire onto a stationary red machine. The tire is the primary discrete solid object undergoing physical manipulation (rotation, positioning) by the person's hands.

No shifting backgrounds or fluid/environmental motion; background elements (red machine structure, walls, floor) remain stationary throughout the sequence, indicating no ambient environmental motion (fire, water, smoke, wind).


A hand appears at the bottom of the frame, moves rightward to draw a yellow starburst shape on a whiteboard surface, then writes text within the starburst. The camera maintains a top-down fixed perspective throughout.

A hand (discrete object) is moving to draw a starburst and then write 'LATEST' inside it, showing explicit physical motion due to the drawing action.

The background is a static white surface with fixed text. There is no shifting background or fluid/environmental motion (fire, water, smoke, wind).


A person's hands grasp brown, round potatoes from a water-filled sink, peel them under running water to expose white interiors, and rinse the peeled potatoes; a bowl of chopped onions sits adjacent to the sink. The camera remains close-up, following the hands’ motion with minimal movement.

A hand interacts with potatoes, peeling them. The hand and potato are discrete solid objects moving due to manual peeling actions.

The background (sink, faucet, tray of peels) shows no uniform shifting. Water from the faucet is a controlled source, not ambient fluid motion.


A person wearing a light blue denim jacket plays a flute, holding it to their mouth and slightly turning their head. They stand in front of a wall adorned with numerous colorful dreamcatchers featuring feathers and beads. The camera follows their movement with a slight pan to the right.

The person is moving their hands and head while playing a didgeridoo, representing discrete solid-object motion due to their own physical actions.

Background elements (hanging dreamcatchers and other items) show no uniform shifting or fluid motion; no fire, water, or wind-driven environmental phenomena are present.


A blonde girl in a purple shirt and pink shorts sits on a wooden floor, holding a black and blue power drill with both hands, focused on drilling into an object. Behind her, another person in red shorts sits near a metal frame structure. The camera remains static, capturing the scene from a slightly angled top-down perspective with minimal background details.

The girl is manipulating a toy car (or similar object) with her hands; the toy moves as she pushes or adjusts it.

Background elements (floor, furniture, bag) are stable; no shifting or fluid motion (fire, water, wind) detected.


A pair of hands manipulates a medium-sized dark metal container over a fire pit filled with ashes and charred wood, lifting and repositioning it before moving it away to reveal a small metal pot nearby. The fire pit is bordered by stones, with grass visible to the right. The camera maintains a static top-down perspective throughout.

Person's hands and container are moving to pour liquid into a cup, exhibiting discrete, solid-object motion.

Static background elements (tarp, ground, vegetation) show no uniform shifting; fire is present in the background but not dominant motion.


RAW CAPTION: Got it, let's see. The video shows a group of men in gray suits clapping. They're standing in a line, maybe a choir or ensemble. The camera is panning from left to right, showing different parts of the group. The background is a red curtain, but we don't need to focus too much on that. The men are all moving their hands to clap, so their motion is clapping. The number is a large group, all in gray suits, same color, so they're uniform. Spatially, they're in a line, moving together. Camera movement is panning left to right. Let me structure the caption.

Start with the main action: group of men in gray suits clapping. Then describe their movement chronologically. The camera pans from left to right, showing the group. Mention the background is minimal. Let's check the rules. Need to be concise, chronological. So first, the group is clapping, camera moves, shows different parts. Number: large group, all in gray suits. Spatial: standing in a line. Camera perspective: panning from left to right.

Putting it all together: A large group of men in gray suits stand in a line, clapping rhythmically; the camera pans from left to right, capturing their synchronized hand movements as they shift positions within the line. Background is a plain red curtain. But need to keep background minimal, so maybe just mention the curtain briefly. Wait, rule e says minimize background unless essential. The curtain is part of the setting, but maybe not essential for motion. Let's see. The main focus is the men clapping. So the caption should focus on their actions.

Wait, the example in the rules: the video is of people clapping. So the caption should describe their clapping motion, number, appearance, camera movement. Let's try: A large group of men in matching gray suits clap in unison, moving their hands rhythmically; the camera pans horizontally from left to right across the group, maintaining focus on their synchronized gestures. The background features a red curtain, but the primary focus is on the men's coordinated clapping. Wait, but need to keep it concise. Let's make it shorter.

"A large group of men in gray suits stand in a line, clapping rhythmically; the camera pans from left to right, capturing their synchronized hand movements as they adjust positions within the group."

Check the rules: a) motion and behavior in chronological order—clapping, then camera panning. b) appearance: gray suits, large group. c) spatial: line, camera panning from left to right. d) camera perspective and movement: panning left to right. e) background minimal—just mention the curtain briefly if needed, but maybe not necessary. Wait, the background is a red curtain, but the main action is the men. So perhaps the caption can be: A large group of men in gray suits clap together in a line; the camera pans from left to right, showing their synchronized hand movements and slight shifts in position. Background is a plain red curtain. But need to keep it concise. Let's see the example from the problem: the first frame shows the group, then the camera pans. So the key points are the men clapping, camera panning left to right, group in gray suits.

Final version: A large group of men in gray suits clap rhythmically while standing in a line; the camera pans from left to right, capturing their synchronized hand movements as they adjust their positions. The background features a red curtain.

Wait, but rule e says minimize background. So maybe don't mention the curtain. But the problem's video has a red curtain as background. But if it's not essential, perhaps omit. Wait, the problem states "exclude text recognition, named characters, or stylistic analysis", but background is not a named character. Hmm. Let's see the original video description: the background is a red curtain, which is part of the setting. But the main focus is on the men's actions. So the caption should mention the men's actions, number, appearance, camera movement. Maybe the curtain is not necessary, but let's check.

The user says "keep background descriptions minimal unless essential for understanding motion". Here, the curtain is a background element, but the motion is the men clapping. So probably don't need to mention the curtain. So the caption would be: A large group of men in gray suits stand in a line, clapping rhythmically; the camera pans from left to right, capturing their synchronized hand movements as they shift positions within the group.

Yes, that's concise. Let's check all rules:

a) motion: clapping, camera panning. Chronological: first the men clap, then camera moves.

b) appearance: large group, gray suits.

c) spatial: standing in a line, camera p

A group of people in suits are actively clapping, gesturing, and moving their upper bodies; their motion is discrete and attributable to intentional locomotion and hand movements.

The background consists of a static red curtain with no shifting or environmental fluid motion (e.g., no fire, water, or wind effects).


Two individuals seated on patterned beds face each other; one wears a red top and purple head covering with white patterns, the other a black vest over a light blue shirt. They alternate between high-fiving and clapping hands together, moving arms in quick, rhythmic motions. The camera maintains a static perspective with minimal shake.

Two individuals (discrete solid objects) engage in rhythmic hand movements (rock-paper-scissors game); their hands and upper bodies move intentionally due to physical exertion, with clear, trackable motion.

The background (plain wall and bed) shows minimal uniform shifting, consistent with slight handheld camera movement but not dominating the scene. No fire, water, smoke, or wind is present; no environmental motion is observed.


Three individuals, including one in red and one in yellow, enter the dark water from a snow-covered shore, creating splashes as they swim and move; the person in red initiates the jump while others follow, with the snowy bank visible to the left. The camera remains static, positioned on the shore, capturing the action from a slightly elevated angle with minimal background detail.

Two people are visible in the water, actively swimming and interacting; their movements are distinct and trackable as discrete solid objects.

The snowy cliff edge and distant horizon remain stable with no uniform shifting, indicating no significant ambient environmental motion (water ripples are secondary effects of human activity).


A person's hands are actively moving to write on a sheet of paper, representing discrete solid objects (hands) engaging in a physical action.

The background consists of a static table surface with no discernible shifting, fluid motion, or environmental phenomena (e.g., fire, water, wind).
