RAW CAPTION: Got it, let's break this down. The video shows a jet ski with people on it moving across water. First, identify the main subjects: a jet ski with multiple people (maybe 3-4?), moving from left to right. Describe their motion: the jet ski is moving, creating a wake. Appearance: jet ski is white with blue accents, people are wearing life jackets (colors like yellow, maybe others). Spatial: the jet ski is in the center, moving towards the right. Background is water with distant shore, but keep background minimal. Camera perspective: seems to be a steady shot, maybe following the jet ski. Chronological order: starts with jet ski in water, moves, continues moving.

Check the rules: focus on motion, chronological. Number of people: let's see, the video shows 3 people maybe? Or 4? The first frame has maybe 3. But need to be concise. Appearance: people on jet ski, life jackets. Motion: moving across the water from left to right. Camera: steady, tracking the jet ski.

Now structure the caption:

- Start with the main subject's action: A group of people on a jet ski moves across calm water, traveling from left to right.
- Appearance: The jet ski is white with blue seating; three individuals, including one wearing a yellow life jacket, are seated.
- Motion: The jet ski creates a small wake as it moves steadily toward the right side of the frame.
- Camera: The camera remains fixed, capturing the jet ski from a medium distance as it travels across the water.
- Background: A distant shoreline with greenery is visible but not detailed.

Wait, need to be concise. Let's trim. Rule f: exclude text, named characters, stylistic. So "group of people" not specific. Number: maybe "three people". Appearance: jet ski is white with blue, people on it. Motion: moving left to right, creating wake. Camera: steady shot, tracking.

Wait, the video starts with the jet ski in the middle, then moving. So chronological: the jet ski with three people moves across the water from left to right, creating a wake. The camera follows their movement steadily.

Check output format: must be a paragraph. So:

Three people on a white jet ski with blue seating move across calm water, traveling from left to right. They create a small wake as the jet ski steadily advances. The camera maintains a steady shot, tracking the jet ski from a distance as it moves toward the right side of the frame.

Check if minimal background: yes, only mention if essential. The background is shoreline but minimal. The rules say minimal background unless essential for understanding motion. Since the motion is on water, maybe the shore is not essential, but if we mention it, it's okay as a reference. Wait, the example in the problem doesn't mention background, so maybe better to exclude. Wait, the first frame shows a shoreline in the distance. But the task says "exclude text recognition... keep background descriptions minimal unless essential for understanding motion". The motion is the jet ski moving, so the shore is background but not essential. So maybe not include.

So revised:

A group of three people on a white jet ski with blue seating move across calm water, traveling from left to right. The jet ski creates a small wake as it steadily advances. The camera maintains a fixed perspective, tracking the jet ski's movement across the water.

Wait, is "fixed perspective" correct? The video is a steady shot, so camera is stationary but tracking the jet ski. Wait, the camera might be panning? Wait, in the video, the jet ski moves, and the camera seems to follow it. Let's see the frames: the jet ski is moving left to right, and the camera is following, so the camera moves with it. Wait, the problem says "conclude with camera perspective and movement". So "camera follows the jet ski steadily".

Wait, let's check the video frames: in the first frame, the jet ski is on the left side, then moves to the right. The camera is probably panning right to follow it. So camera movement: panning right.

So:

Three people on a white jet ski with blue seating move across calm water from left to right, creating a small wake as they steadily advance. The camera pans right, maintaining a steady shot that tracks the jet ski's movement.

Yes, that's better. Now check rules:

a) motion and behavior in chronological order: jet ski moves left to right, people on it. Correct.

b) appearance and number: three people, white jet ski with blue seating. Correct.

c) spatial relationships: left to right movement. Correct.

d) camera perspective and movement: pans right, steady shot. Correct.

e) background minimal: the shore is in the distance but not described

Multiple people are pushing a red car, causing it to move forward. The car's motion is driven by human physical force, and the people's actions are clearly visible as they apply pressure to the vehicle.

The background consists of stationary buildings and ground; no fluid or environmental motion (fire, water, smoke, wind) is present. Background elements do not shift uniformly, indicating no camera-induced motion.


RAW CAPTION: Got it, let's tackle this. The video starts with a man in a patterned shirt arranging red flowers in a vase. He's standing at a wooden table. There's a decorative red and green circle on the wall behind him. Then there's a transition to a yellow background with text, but according to the rules, we shouldn't include text recognition. So focus on the motion: the man adjusts the flowers, moves his hands around the vase. The next part is a close-up of hands handling something yellow with branches, but wait, the rules say exclude text recognition. Wait, the problem says to exclude text recognition, so the yellow screen with "Visit TheFlowergod.com..." is text, so we skip that. The main action is the man arranging flowers. Let's structure it chronologically.

First, the man is standing at a table, adjusting red flowers in a vase. He moves his hands around the flowers, positioning them. Then the scene cuts to a close-up of hands holding yellow branches (but maybe that's part of the flower arrangement? Wait, the video has two parts: first the man arranging, then a transition to yellow with text. But the caption should be about the main video. Wait, the user provided a video description with two frames. Let's see:

First frame: man in patterned shirt, red flowers in vase, wooden table, background with wooden wall and decorative circle. He's adjusting the flowers, hands on the stems. Then second frame: transition to yellow background with text, but the rules say exclude text recognition. So the main action is the man arranging. Then the next part is a close-up of hands with yellow branches, but the caption should be chronological.

Wait, the problem says "describe the provided video" in chronological order. The video has two parts: the man arranging, then the transition. But the rules say "exclude text recognition", so the text part is not to be described. So the main motion is the man adjusting the red flowers in the vase, then the camera cuts to a close-up of hands holding yellow branches (maybe part of the flowers). Wait, but the problem's example: the first frame shows the man, then the second frame shows the yellow background with text. But the rules say exclude text recognition, so focus on the motions of the people/objects.

Wait, the task is to generate a concise chronological paragraph. Let's break down each frame:

Frame 1: Man (patterned shirt, gray hair) stands at wooden table, adjusting red flowers in a vase. Hands move the flowers. Background: wooden wall with decorative red circle.

Frame 2: Close-up of hands handling yellow branches (maybe part of the flower arrangement), then the yellow background with text (which we exclude).

But according to the rules, focus on motion and behavior. So:

- Man in patterned shirt adjusts red flowers in a vase, moving hands to reposition stems.

- Transition to close-up of hands holding yellow branches against a yellow background.

But wait, the problem says "exclude text recognition", so the text part (the yellow background with text) is to be omitted. But the video includes that part. Wait, the user says "the provided video", which includes those frames. But the rules for the caption: exclude text recognition. So the text "Visit TheFlowergod.com..." is text, so we don't mention it. So the second part is a close-up of hands holding yellow branches (the yellow background might be part of the scene, but since it's a background, but maybe the yellow branches are the object). Wait, the second frame description says "a close-up of hands holding yellow branches", so the object is yellow branches, hands are handling them.

So chronological order: first, the man adjusts red flowers in a vase at a wooden table, then the camera shows a close-up of hands manipulating yellow branches.

Now, appearance: man has gray hair, patterned shirt (white with dark patterns), red flowers (multiple, in a vase), wooden table. The yellow branches are in a close-up, hands are holding them.

Spatial relationships: man is in front of the wooden wall with decorative circle, table in front of him. The close-up is of hands and yellow branches.

Camera movement: first, medium shot of the man, then cuts to close-up.

Background: minimal description. So wooden wall, but not too much.

Putting it all together:

A man with gray hair wearing a patterned shirt adjusts red flowers in a vase on a wooden table, repositioning stems with his hands. The scene transitions to a close-up of hands manipulating yellow branches against a yellow background.

Wait, but the rules say "keep background descriptions minimal unless essential for understanding motion". The yellow background is part of the scene, but maybe not essential. Wait, the first scene's background is wooden wall, which is the main setting.

The man is moving his hands and body while manipulating a red object (likely a fruit or flower). The red object is also moving relative to the man's hands.

The background (wooden wall and yellow text frame) is static with no fluid or gaseous motion. The only motion is from the man's deliberate movements.

Background elements (wallpaper, table items) show no uniform shifting or environmental motion (fire, water, smoke, wind). The scene remains static in background components.


...<caption_output>  So the caption should be a single paragraph.  Let's draft:  A person wearing a purple shirt and jeans adjusts a tool near a bicycle wheel, then kneels to work on the bike's chain and rear gear mechanism on a concrete floor. The scene shifts to two individuals standing outdoors—one in a white polo shirt and the other in a black shirt—conversing near a patio with a table and chairs. The camera starts with a close-up of the hands and wheel, moves to a wider view of the person working, and ends with a medium shot of the two individuals.  Check rules:  a) Motion chronologically: adjusting tool, kneeling to work, then two people talking.  b) Appearance: purple shirt, jeans, bracelet; white polo, black shirt.  c) Spatial: in front of bike, outdoors near patio.  d) Camera: close-up, wider, medium shot.  e) Background minimal: concrete floor, patio.  f) Exclude text: no text recognition.  g) No reasoning.  Yes, that works. </think>  <caption_output>A person in a purple shirt and jeans adjusts a tool near a bicycle wheel, then kneels to work on the bike's chain and rear gear mechanism on a concrete floor.

RAW CAPTION: Got it, let's tackle this caption. First, the video shows hands flipping a scrapbook. The main subject is the hands and the scrapbook. Let's break down the sequence.

In the first frame, hands are holding a blue scrapbook with floral and Christmas designs. Then, they flip it open to show a red and white page with a circular frame. The hands are moving the book, so the motion is flipping through pages.

Appearance: The scrapbook has colorful pages, each with different designs (blue with flowers, red with patterns). Hands are manipulating it. Spatial: The hands are in front of the book, moving it across the white surface. Background is minimal, just a white table.

Need to keep it chronological: start with holding the book, then flipping to reveal different pages. Mention the motion (flipping), colors of the pages (blue, red, etc.), but not text since rule f says exclude text recognition.

Camera perspective: It's a fixed shot, top-down maybe? The video shows the book on a table, camera is above, so top-down. No movement mentioned, so camera is static.

Check rules: a) motion and behavior (flipping book), b) appearance (colors, size), c) spatial (hands in front of book), d) camera (top-down, no movement), e) background minimal, f) no text.

Putting it together: Hands open a colorful scrapbook, first showing a blue page with floral and Christmas motifs, then flipping to reveal a red and white page with a circular frame. The hands manipulate the book, turning pages sequentially across a white surface. Camera remains stationary, top-down.

Wait, need to be concise. Let's make sure it's chronological: first frame shows blue page, then hands flip to red page. So "A pair of hands opens a blue scrapbook with floral and Christmas-themed pages, flipping it to reveal a red and white interior page with a circular frame. The hands continue to manipulate the book, turning pages across a white surface." Then camera: "The camera maintains a static top-down perspective throughout."

Wait, the output format needs to be a paragraph. Let's check the rules: "concise, chronological paragraph". So:

A pair of hands manipulates a colorful scrapbook, initially holding a blue page with floral and holiday designs, then flipping to expose a red and white interior page with a circular frame. The hands continue turning the book's pages across a white surface. The camera remains stationary in a top-down view.

Wait, check if we need to mention the number of hands: it's "a pair of hands" (two hands), but maybe just "hands" as in plural. Also, in the video, the hands are moving the book, so the motion is flipping.

Also, the scrapbook's pages change color: blue to red. So chronological order is first blue page, then red page.

Let me check the video frames:

0.0: blue page (floral, Christmas tree, etc.)

0.3: hands flipping to next page (red)

0.6: red page with circular frame.

So the sequence is hands holding the book, flip to reveal red page.

So the caption should describe that.

Also, background: minimal, white surface. So "across a white surface" (table).

Now, putting it all together, concise:

Two hands open a blue scrapbook with floral and holiday motifs, flipping it to reveal a red and white page featuring a circular frame. The hands continue turning the book’s pages on a white surface. The camera stays in a fixed top-down position.

Wait, check for text recognition: no, we don't mention the text on the page. The rule f says exclude text recognition, so we don't talk about the text inside the pages. Just the colors and designs (floral, holiday motifs).

Yes, the scrapbook has "floral and holiday motifs" as appearance.

Check all rules:

a) Motion: hands opening/flipping book.

b) Appearance: blue scrapbook (color, size? maybe "colorful", but the main colors are blue and red).

c) Spatial: hands in front of the book, moving it.

d) Camera: top-down, static.

e) Background: minimal, white surface mentioned.

f) No text.

So the caption should be concise.

Let me draft:

A pair of hands manipulates a colorful scrapbook, first displaying a blue page with floral and holiday designs, then flipping to reveal a red and white interior page with a circular frame. The hands continue turning the pages across a white surface. The camera remains stationary in a top-down view.

Check for conciseness: maybe "Two hands open a blue scrapbook with floral and holiday motifs, flipping it to a red and white page with a circular frame. The hands turn the book’s pages on a white surface,

A hand is manipulating a handmade card by turning its pages, causing discrete physical motion of the card.

Background is static white surface with no shifting elements or environmental motion (fire, water, wind).


and

Multiple dancers in formation move synchronously across the court, exhibiting locomotion (dancing) and spatial repositioning; solid, distinct objects moving via explicit physical forces (muscular effort).

Background elements (seats, walls) show no significant shifting or fluid motion; no fire, water, or wind visible. Ambient environmental motion is absent.


RAW CAPTION: Got it, let's tackle this. First, I need to generate a concise caption following the rules. Let's look at the video frames.

In the first frame, there's a room with a white couch, two people. One in an orange shirt is sitting on the couch, another in a purple shirt is standing near the door. Then, in the next frames, the person in purple moves towards the couch, and the person in orange stands up. Then the screen shows "BUSINESS UNIVERSAL" with some text.

Wait, the user says to focus on motion and behavior. Let's list the sequence:

- Initially, the person in orange is seated on the couch; the person in purple is standing near the door (to the right of the couch, maybe?).
- Then the person in purple moves towards the couch, approaching it.
- The person in orange stands up from the couch.
- Then the scene transitions to a title card "BUSINESS UNIVERSAL".

Need to mention the main subjects (two people), their actions (standing up, moving towards), spatial relationships (one on couch, one standing near door then moving to couch). Also, the camera perspective: the video is a medium shot, maybe static, then cuts to title card.

Wait, rules say exclude text recognition, so the French text "C'est vraiment très simple." etc. don't count.

So chronological order:

1. Two people: one seated on a white couch (orange shirt), another standing near the door (purple shirt).
2. The standing person moves toward the couch, approaching from the right.
3. The seated person stands up from the couch.
4. The scene transitions to a title card displaying "BUSINESS UNIVERSAL".

Wait, but the frames given are [0.0] to [5.0], so the sequence of events: initial positions, then movement, then title.

Need to keep it concise, mention appearance (colors: orange, purple), number (two people), motion.

Check the rules: "Focus primarily on the motion and behavior of main subjects (people/animals/objects) in chronological order. Briefly describe their appearance and number (color, size, orientation). Mention spatial relationships if relevant (e.g., in front of, to the left). Conclude with the camera perspective and movement."

So:

- Two people: one seated on a white couch (wearing an orange shirt), another standing to the right of the couch (wearing a purple shirt).
- The standing person moves toward the couch, approaching from the right, then steps forward.
- The seated person stands up from the couch.
- The scene then transitions to a title card with "BUSINESS UNIVERSAL" displayed.

Wait, the camera movement: the initial frames are a static shot (medium view), then cuts to title card. So camera perspective is static, then cuts to a title card (top-down? No, title card is full screen).

Wait, the last frame is "BUSINESS UNIVERSAL" in large letters. So the camera cuts to that.

So final caption should be:

Two people are present: one seated on a white couch wearing an orange shirt, and another standing to the right of the couch wearing a purple shirt. The standing individual moves toward the couch, approaching from the right, while the seated person stands up from the couch. The scene transitions to a title card displaying "BUSINESS UNIVERSAL" in large text.

But need to check rules: "exclude text recognition, named characters, or stylistic analysis." So the title card text is not to be described? Wait, the rules say "Exclude text recognition, named characters, or stylistic analysis." So the title "BUSINESS UNIVERSAL" is text recognition, so should we not mention it? Wait, no—the example in the rules says to "conclude with the camera perspective and movement". The transition to the title card is a cut. So maybe:

The two individuals interact; the person in purple moves toward the couch while the person in orange stands up. The scene cuts to a title card.

But let's re-read the rules: "Mention spatial relationships if relevant (e.g., in front of, to the left)." So for the initial scene: the person in orange is seated on the couch, the person in purple is standing to the right of the couch (since in the first frame, the couch is in the center, door is behind, so purple person is on the right side of the couch). Then as the video progresses, the purple person moves toward the couch (so from right to the couch's position), and the orange person stands up.

Also, check the background: minimal background description, so "a room with wooden furniture and a television" but need to keep minimal. The rule says "background descriptions minimal unless essential for understanding motion." So maybe just mention the couch, people.

Let's draft:

In

Two people (one sitting, one standing) moving due to natural locomotion.

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


A man in dark clothing sits on a green patterned couch, holding a piece of paper. He reads from it, then looks up, speaks, and gestures with his hands. A flower arrangement is in the foreground to his right, with a bookshelf and green-draped table visible in the background. The camera remains stationary, capturing the scene from a fixed angle.

A man is sitting on a couch, holding a paper, and making hand gestures while reading.

Background elements (wall, table, flowers) are static. No fluid or environmental motion observed.


A small girl with red hair, wearing a colorful floral romper and barefoot, hops forward across a chalk-drawn hopscotch grid on a concrete path, then stands on the grid. The background includes a grassy yard and a house. The camera remains stationary, capturing her movement from a ground-level perspective.

A girl is moving by hopping and stepping on a hopscotch grid. Her motion is discrete and driven by voluntary locomotion (hopping).

Background (house, grass, sidewalk) shows no shifting or fluid motion. No fire, water, smoke, or wind phenomena observed.


A pair of hands adjusts a black bow tie on a person wearing a black jacket and striped shirt; the hands manipulate the bow tie, shifting it to center and smooth its shape against the neck, with the camera maintaining a close-up, static view focused on the neck area and bow tie adjustment.

Discrete solid objects: hands manipulating a bow tie (applied force and physical adjustment), with minimal movement of the person's torso/neck.

Background shows stationary outdoor foliage with no significant motion or fluid elements; no wind, water, or smoke observed to dominate the scene.


A person wearing a black jacket with white stripes and a dark beanie plays a silver clarinet while seated. A brown couch is visible behind them. The camera remains stationary in a medium shot, facing the individual directly.

A person is playing a clarinet; hands and fingers move to press keys, indicating discrete object motion due to muscle action.

Background elements (couch, wall) are static with no shifting. No fire, water, smoke, or wind detected.

The camera remains stationary throughout, capturing the individual’s continuous guitar playing motion.

The man is actively playing the guitar, with visible hand and body movements as he strums and holds the instrument.

The background (window, walls, desk) is static with no fluid motion or shifting. No environmental elements (fire, water, smoke, wind) are present.


RAW CAPTION: Okay, let's tackle this video captioning task. First, I need to understand what the user wants. They provided a video snippet and specific rules for the caption. Let me read through the rules again carefully.

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

Looking at the video description, there are two shirtless boys in a room. One is holding a punching bag, the other is punching it. The first boy is in blue shorts, the second in black. They're on a blue mat, with a yellow wall and some stacked mats in the background.

Chronological order: At the start, the boy in blue holds the bag up. Then the other boy starts punching it. The punching continues, maybe the bag swings back and forth.

Appearance: Both boys are shirtless. Blue shorts vs. black shorts. Number is two.

Spatial relationships: The boy with the bag is on the left, the one punching is on the right. The punching bag is held up, so the person punching is to the right of the bag holder.

Camera perspective: The video description mentions it's a bit shaky, maybe handheld. The camera seems to be stationary but with some movement, maybe slight shake as noted in the rules.

Background: Minimal details, just a yellow wall and some stacked mats. Not essential for motion, so keep it brief.

Avoid mentioning the time (0.3 seconds), focus on the action. Start with the setup: one boy holding the bag, then the other punching. Continue the sequence.

Check the output format: must be in <caption_output> tags, no extra text. Keep it concise.

Let me draft:

Two shirtless boys, one in blue shorts holding an orange punching bag upright, the other in black shorts punching it rhythmically. The bag swings between them as the boy in black alternates punches and kicks. The camera remains stationary but slightly shaky, capturing the action from a low angle in a dimly lit room with yellow walls and stacked mats.

Wait, the rules say background descriptions minimal. Maybe omit the yellow walls? But the user example includes "dimly lit room with yellow walls". Hmm. Rule e says "keep background descriptions minimal unless essential for understanding motion". So if the yellow walls and stacked mats aren't necessary for the motion, maybe skip. But the video shows a room with those elements. However, since the main action is the punching, maybe it's okay to mention the room being dimly lit. Wait, the original video description mentions "yellow walls" and "stacked mats", so perhaps they are part of the minimal background. Let's check the example output in the user's instructions.

The user's example output (though not provided here) would likely include just enough background. The user's problem statement says to "keep background descriptions minimal unless essential for understanding motion". So if the background isn't affecting the motion, just mention the room's general setting. The dimly lit room might be part of the background, but maybe the main point is the two boys and the punching bag.

Wait, looking at the initial video frames: "yellow walls", "stacked mats". Since the video is in a room, but the main action is the two boys. The background is not critical, but perhaps "dimly lit room" is acceptable as part of minimal background.

Also, the camera: the user example mentions "stationary but slight shake". The video might have a slight shake. The original description in the problem says "slight shake" in the rules as an example.

So combining all: Two shirtless boys, one in blue shorts holding an orange punching bag upright, the other in black shorts punching it rhythmically. The bag swings as the boy alternates punches and kicks. The camera is stationary but slightly shaky, capturing the action in a dimly lit room.

Wait, but need to specify chronological order. Let's check the video frames:

[0.0] Both are present. The first boy is holding the bag up. The second boy is punching.

[0.3] The boy in blue holds the bag, the other punches.

So the sequence is: One boy holds the bag, the other punches. Then they continue. So the caption should describe the action in order.

The caption should be:

Two shirtless boys interact in a room. One, wearing blue shorts, holds an orange punching bag upright while the other, in black shorts, punches it rhythmically. The bag swings between them as the second boy alternates punches and kicks. The camera remains stationary with slight shake, capturing the action in a dimly lit space with minimal background details.

Wait, need to mention the number, appearance, motion. Let's check the rules again.

a) Chronological order: Start with holding the

Two shirtless men and a punching bag (or similar object) are moving: one man is punching the bag, causing it to swing, while the other holds it steady.

No significant shifting of background elements (walls, window, equipment) and no dominant fluid/environmental motion (e.g., fire, water, wind).


Two people in the center—a woman in a light patterned shirt and red pants, and a man in a white shirt and dark pants—dance closely, holding hands. The woman bends down, then stands, while the man steps back. A third person in a maroon shirt moves from the left, joining the interaction. Other participants in the background move, some holding hands. The camera remains steady with slight shifts, capturing the scene from a fixed position.

Multiple solid objects (people) are moving due to locomotion (dancing) and physical interactions (e.g., holding hands, turning). Their motion is distinct and trackable via bounding boxes.

Background elements (walls, carpet pattern) show no uniform shifting or fluid motion (fire, water, smoke). The environment is a static indoor dance floor with no environmental fluids.


A light-skinned hand adjusts multiple guitar strings on a wooden bridge with visible grain, moving the strings slightly in a downward motion. The hand is positioned in front of the guitar body, with a black amplifier partially visible in the background. The camera maintains a stationary close-up perspective throughout.

A hand (discrete solid object) is moving along the strings of a bass guitar, demonstrating explicit physical motion from playing.

The background features a static Marshall amplifier with no shifting elements or fluid/environmental motion (fire, water, smoke, wind).


Two men, one in gray long-sleeve and the other in white t-shirt, stand near a bare tree against a light-colored wall. The gray-shirted man raises his arm upward to inspect something on the tree, while the white-shirted man stands beside him, observing. The camera pans slightly left to follow the gray-shirted man’s movement as he extends his arm toward the tree branches.

Two people are visible. The individual in the gray shirt actively raises their arm to interact with a tree branch (reaching upward), demonstrating discrete human locomotion. The person in the white shirt remains stationary as an observer.

The background (building wall and bare tree branches) shows no significant environmental motion; tree branches exhibit minimal swaying but no dominant fluid or wind-driven effects. No fire, water, or smoke present.


RAW CAPTION: Got it, let's break this down. The video shows a child and a dog. First, the child is holding pink shoes. Then, the child walks towards the grassy area, and the dog follows. Wait, the child is walking, and the dog is on a leash. Let's check the chronological order.

Start: The child is standing on a sidewalk, holding pink shoes. Then the child turns and walks along the sidewalk, pulling a leash with a small light-colored dog (maybe a French Bulldog?) following. The dog is ahead, and the child is behind, leading it. The background has a grassy area and sidewalk. The camera angle seems to be top-down initially, then follows the child's movement.

Need to describe motion: child starts holding shoes, turns, walks along sidewalk, dog follows. Appearance: child has light hair, gray shirt, dark shorts. Dog is small, light brown. Spatial: child walks in front of the dog? Wait, no, the dog is on a leash, so child is in front, dog behind? Wait, in the frames, the dog is moving ahead as the child leads. Wait, the video sequence: frame 0-1: child holding shoes. Frame 2: child turns, walks. Frame 3: child is walking, dog appears. Frame 4-5: child and dog moving along the path.

So main subjects: child (male, light hair, gray shirt, black shorts with white stripes) and small light-colored dog (probably French Bulldog) on leash. The child holds a pink leash, starts by holding shoes, then walks along the sidewalk, leading the dog which follows. The background has a sidewalk and grassy area. Camera is top-down, following the child's movement as they walk along the path.

Now, structure the caption: chronological order. Start with child holding shoes, then turning, walking, dog follows. Mention appearance, spatial, camera.

Let's draft:

A small child with light brown hair, wearing a gray long-sleeve shirt and black shorts with white stripes, stands on a concrete sidewalk holding pink shoes. The child turns and walks along the sidewalk, pulling a leash attached to a small light-brown dog. The dog follows closely behind the child as they move toward a grassy area. The camera maintains a top-down perspective, following the child's movement along the path.

Wait, check the rules: background minimal unless essential. The grassy area is part of the path, so maybe mention the path as concrete and grassy area. The main action is child walking with dog, starting with shoes.

Wait, the first frame shows the child holding shoes, then in frame 2, the child is walking, holding a leash (which was the shoes? Wait, the pink shoes are on the leash? Wait, no, the first frame: child is holding pink shoes, then in frame 2, the child is holding a leash. Oh, wait, maybe the shoes are attached to the leash? The pink shoes are part of the leash? Wait, the video description says in the first frame the child is holding pink shoes, then in frame 2, the child is holding a leash with the pink shoes attached? Maybe the shoes are attached to the leash. Let me check the frames:

Frame 0: child holding pink shoes (maybe the shoes are on a leash, so the leash is attached to the shoes).

Frame 2: child walks, holding the leash (with the shoes attached?).

Wait, the video sequence: the child is holding pink shoes, then walks along the sidewalk, and the dog is on the leash. So the pink shoes are part of the leash. So the child is holding the leash with the shoes, then starts walking, and the dog follows.

So the main points:

- Child starts holding pink shoes, then walks along sidewalk with dog on leash.

- Child's appearance: light hair, gray shirt, black shorts.

- Dog: small, light brown, following the child.

- Background: concrete sidewalk and grassy area.

- Camera: top-down, follows the movement.

Now, concise paragraph.

Let's put it all together:

A small child with light brown hair, wearing a gray long-sleeve shirt and black shorts with white stripes, stands on a concrete sidewalk holding pink shoes. The child turns and walks along the path, leading a small light-brown dog on a leash that is attached to the shoes. As the child moves forward, the dog follows closely behind. The camera maintains a top-down view, tracking the child's progression along the sidewalk toward a grassy area.

Wait, but need to check the rules. Keep background minimal. So maybe "concrete sidewalk" is enough for background. Also, "the dog follows closely behind" — yes.

Check if "attached to the shoes" is necessary? Wait, the first frame the child

The child (solid object) is walking on pavement, pulling a small dog (solid object) via a leash. Both exhibit locomotion due to physical forces (walking), with clear bounding box tracking.

The concrete pavement and grass background remain static throughout, with no shifting or fluid motion. No fire, water, smoke, or wind dominates the scene, satisfying the Ambient Rule criteria.

RAW CAPTION: Okay, let's tackle this video caption request. First, I need to understand the user's requirements. They want a concise, chronological paragraph that describes the video based on the provided frames. The rules are specific, so I need to make sure I follow them all.

Looking at the video frames: there's a person in a blue shirt and shorts, white shoes, throwing a yellow frisbee on a grassy field with a soccer goal in the background. The sequence shows the person winding up, throwing, and then the frisbee in mid-air.

The main subject is the person. They start in a throwing stance, then release the frisbee. The frisbee is yellow, and the person is wearing blue, shorts, white shoes. The background has a soccer goal and hills, but according to the rules, I should keep background minimal unless essential. The camera seems stationary, maybe a slight shake?

Need to mention chronological order: first, the person in the throwing motion, then releasing the frisbee, which flies through the air. Also, check the appearance: blue shirt, denim shorts, white shoes. Spatial relationships: the frisbee is in front of the person when thrown.

Camera perspective: the video seems to be shot from a fixed position, maybe a slight shake as per the frames. Wait, the user says to conclude with camera perspective and movement. The example output mentions "static camera with slight shake." Let me confirm. The frames look like they're from a handheld camera maybe, but the instruction says to note the movement. If the camera is moving, but in the description, maybe it's static. Wait, the user's example might have a slight shake. The frames here might have a slight shake because of the video quality.

Wait, the user's rules say "conclude with the camera perspective and movement (e.g., top-down, pan left, slight shake)." So in the caption, after describing the actions, state how the camera is positioned. Since the frames are from a ground-level view, not top-down, and if it's static with a slight shake, that's the movement.

So the caption should start with the person's action: starting in a throwing stance, then throwing the frisbee. Describe their appearance briefly: blue shirt, denim shorts, white shoes. Mention the frisbee is yellow and in motion. Background is minimal, maybe just the field and goal. Then the camera is static with slight shake.

Wait, the user says to exclude text recognition, named characters, etc. So no mention of the person's name. Focus on actions.

Let me structure it:

A person in a blue shirt, denim shorts, and white shoes stands on a grassy field, facing a soccer goal. They raise their arm in a throwing motion, then release a yellow frisbee that arcs through the air. The person's body turns slightly as they follow through. The scene remains static with the camera positioned at eye level, showing minimal background details, and exhibits a slight shake.

Wait, but need to be more chronological. The sequence is: person starts in position, throws, frisbee flies. So maybe:

A person wearing a blue shirt, denim shorts, and white shoes stands on a grassy field, facing a soccer goal. They raise their right arm above their head, then pivot their body to the left, extending their arm forward to release a yellow frisbee. The frisbee travels horizontally in front of them. The camera maintains a static perspective with a slight shake.

Wait, but the initial frame shows the person in a throwing stance, then the next frames show the motion. Need to be precise about the sequence. Let me check the frames again. Frame 0: person with arm up, frame 1: mid-throw, frame 2: arm extended, frame 3: frisbee in mid-air. So the sequence is: person begins in a backswing, then throws, and the frisbee is released.

So the caption should be:

A person in a blue shirt, denim shorts, and white shoes stands on a grassy field, facing a soccer goal. They initiate a throwing motion, winding up with their right arm raised above their head, then pivot to the left to release a yellow frisbee. The frisbee arcs forward through the air as the person follows through with their arm extended. The camera captures the action from a static perspective with slight shake, showing minimal background details.

Wait, need to check the rules: exclude text recognition, named characters, etc. So "a person" is okay. Also, mention appearance: color, size, orientation. The person's size is medium, but maybe not necessary. The orientation is facing the goal.

Wait, the user says "briefly describe their appearance and number (color, size, orientation)". So maybe: "a person

A person in a blue shirt and shorts throws a yellow frisbee; both objects exhibit clear locomotion due to the throw (person's arm swing and frisbee's trajectory) with stable bounding boxes.

The background (grass field, soccer goal, distant hills) shows no fluid motion (fire, water, smoke) or significant wind effects. The ambient environment is calm and static, with no dominant environmental motion.


The video opens with a close-up of a blue cylindrical structure with metal rails. It transitions to a person in a blue and teal wetsuit working on a snowy surface, bending over a green framework covered in nets while handling a red object. The camera then zooms in on the nets, revealing red and green fabric elements moving. The background is a sparse snowy landscape, and the camera shifts from close-up to wide shot to close-up during the sequence.

Two people (one in blue jacket, one in dark jacket) are interacting with a net and a red object. A hand is moving a red object within the net.

The background (snowy ground and structures) is static. No fluid/environmental motion (fire, water, wind) is present.


A person in a white beekeeping suit and wide-brimmed hat approaches two white beehives on wooden stands in a grassy field. They move to the left beehive, use a tool to open its side, then adjust the hive's position or inspect the interior. The background includes trees and grass, but the focus remains on the beekeeper's actions. The camera stays stationary, capturing the sequence from a medium distance.

The beekeeper (a solid, distinct object) is moving through locomotion (walking, bending, interacting with beehives) and performing actions like opening hive frames.

The background elements (trees, ground, beehives) show no uniform shifting or fluid motion. No fire, water, smoke, or wind is visible to indicate ambient environmental motion.


A chef in a white uniform peels yellow potatoes on a wooden cutting board in a modern kitchen. The camera zooms in to show hands peeling a potato, revealing the peeled skin, then pulls back to the chef holding up a peeled potato. The background includes a pot on the stove and knife block with minimal kitchen items visible. The camera transitions between wide shots and close-ups, focusing on the peeling action.

Discrete solid objects (chef's hands and potatoes) exhibit motion due to explicit physical actions (peeling potatoes, transferring potatoes between hands).

Background elements (kitchen cabinets, stove, utensils, red wall) remain static with no uniform shifting or fluid/environmental motion (fire, water, smoke, wind) observed.


An adult in a sleeveless top and a child in a dress sit at a wooden outdoor table, the adult using a fork to eat watermelon while the child holds a piece; the adult then scoops more watermelon from a plate. A third person in a striped shirt and light pants enters from the right. The camera remains stationary with a slight shake.

Two people (adult and child) interact with a watermelon: adult cuts watermelon, child eats and moves; a third person enters and exits the frame. All motions are due to human actions (cutting, eating, walking).

Background shows static grass, road, and trees with no significant fluid motion (water, fire, smoke) or wind-induced movement. Ambient environmental motion is absent.


RAW CAPTION: Got it, let's break this down. First, the video starts with a person in a dimly lit room, sitting on the edge of a bed. They're holding a phone, looking down at it. Then there's a quick cut to a close-up of writing "Innovation" with a pen—first red, then blue. Next, a calendar showing September 3rd, 2014, with a red circle on the 3rd. Finally, a green background with text "READY TO NOTE? 9/3/14".

Now, the rules: focus on motion and behavior chronologically. Main subjects: person, hand writing, calendar.

First scene: person sitting on bed, holding phone (action: looking at phone). Then close-up of hand writing on a white surface (pen moves, writes "Innovation" in red then blue). Then calendar close-up, highlighting the date. Then the text screen.

Need to mention appearance: person is in a shirt, room has lamp, bed, etc., but minimal background. Spatial: person is on bed near window, writing is close-up on surface, calendar is close-up.

Chronological order: starts with person on bed with phone, then writing on paper, then calendar, then text.

Camera movement: first shot is static (room scene), then close-ups for each subsequent scene.

Exclude text recognition (so don't mention "Innovation", just the writing action).

So structure:

1. Person sits on bed, holds phone, looks down.
2. Close-up of hand writing on paper (pen moves, writes).
3. Close-up of calendar showing date with circle.
4. Green screen with text.

Check rules: a) motion chronologically. b) appearance: person in shirt, hand (white pen), calendar (white, red circle). c) spatial: person near window/bed, writing on paper, calendar close-up. d) camera: starts static, then close-ups. e) minimal background. f) no text recognition (so don't say "Innovation", just the action of writing).

Let's draft:

A person in a light blue shirt sits on a bed in a dim room, holding a phone and looking down. The camera then shifts to a close-up of a hand using a white pen to write on a white surface, followed by a close-up of a calendar page displaying September 3rd, 2014, with the date circled in red. The sequence concludes with a green-screened text overlay.

Wait, need to check if background is minimal. The room has a lamp, bed, window, but since it's the first scene, maybe just "dimly lit room" is okay. But rule e says minimal background unless essential. The bed and lamp are part of the scene but maybe okay.

Also, check the order:

[0.0] person on bed with phone.

[1.4] close-up of writing (hand, pen).

[2.5] "Innovation" writing (but rule f says exclude text recognition, so don't mention the word, just the action).

[3.6] calendar.

[4.7] text screen.

So the actions are: person looks at phone, then hand writes (pen moves), then calendar shown, then green screen.

So the caption should list these in order.

Make sure to mention motion: "holds phone and looks down", "hand writes on white surface", "calendar page displayed", "green-screened text overlay".

Check if "person" is the main subject. Yes.

Appearance: person in light blue shirt (color), hand (using pen).

Spatial: person on bed (near window), writing is close-up, calendar is close-up.

Camera perspective: starts with medium shot (person on bed), then close-ups.

So final draft:

A person in a light blue shirt sits on a bed in a dimly lit room, holding a phone and looking down. The camera then shifts to a close-up of a hand using a white pen to write on a white surface, followed by a close-up of a calendar page with the date September 3rd, 2014, circled in red. The sequence ends with a green-screened text overlay.

Wait, but rule g says exclude text recognition, so the "September 3rd, 2014" is part of the calendar, but since it's part of the scene, maybe okay? Wait, the rule says "exclude text recognition, named characters, or stylistic analysis". So if the text is part of the visual (like the calendar date), but the task says "exclude text recognition"—so for example, if the video shows the word "Innovation

A person in a room is writing, and a hand holding a pen is moving to write on paper. These are solid objects moving due to explicit physical forces (hand muscle movement).

No shifting backgrounds or fluid/environmental motion (e.g., fire, water, wind) detected. All scenes show static backgrounds (room, calendar, writing surface) without movement.


A male swimmer in black trunks and goggles swims freestyle in a pool, initially viewed from above with arms extended and creating splashes, then the camera shifts to a side angle showing him continuing the stroke with his right arm reaching forward through the water as he moves forward along the lane marked by blue and white dividers.

A swimmer (human) moving through the water, performing freestyle stroke.

The water motion is a consequence of the swimmer's movement and is not dominant; the background (pool walls and lane dividers) is static and does not shift uniformly.


RAW CAPTION: Got it, let's tackle this. The user wants a caption based on the video description. First, I need to watch the video sequence. The video shows a boxing match. The main subjects are two shirtless men in a boxing ring.

First, the first frame: a shirtless man with a shaved head, maybe with tattoos, is in the ring. Then another shirtless man approaches, maybe a different one. The action is them fighting—throwing punches, grappling.

Let's break down the chronology. Start with the first frame: a shirtless man (bald, muscular) in the ring, possibly with blood on his face. Then the second frame: he's moving towards another shirtless man (maybe with a beard, also muscular) who's reaching out. Then they grapple, the second man is on his back maybe? Wait, no, the sequence is: first frame is a man with his head down, then he turns to face another man, they exchange punches, then they hold each other in the ring.

So, main subjects: two shirtless male boxers. First boxer: bald, muscular, face with red marks (blood maybe). Second boxer: has a beard, muscular, tattooed.

Chronological order: the first boxer (bald) is in the ring, then the second boxer (bearded) approaches, they engage in combat—punching, grappling. Then they push against each other, maybe the bearded one is on the left or right? Wait, the description says "the second man is to the left" but no, in the video, the sequence shows them interacting in the ring.

Background: the boxing ring with ropes, audience in the background. But the rules say minimal background unless essential. So mention the ring ropes, audience is there but minimal.

Camera perspective: seems to be a handheld camera, maybe following the action. The camera movement might be shaky, as it's capturing the live fight.

Now, applying the rules:

a) Focus on motion and behavior: two men boxing in a ring, exchanging punches, grappling.

b) Appearance: two shirtless muscular men. First (bald), second (bearded, tattooed).

c) Spatial: they are in the ring, facing each other, then the second man approaches from the left? Wait, the video sequence: first frame shows one man with head down, then he turns to face another man (second frame), so the second man is approaching from the side.

d) Camera: handheld, slight shake as it follows the action.

e) Background: boxing ring ropes, audience (minimal).

f) Exclude text, names, etc.

So putting it all together:

Two shirtless muscular men engage in a boxing match inside a ring. The bald man with a visible tattoo on his shoulder faces the bearded man, who approaches him. They exchange punches, with the bearded man using his arms to push the bald man, then grappling while the bald man holds the bearded man's arms. The camera follows the action with a slight shake, capturing the intense close combat as the audience watches from behind the ring ropes.

Wait, let's check the video: the frames are [0.0] to [5.0] with the men fighting. The first frame shows the bald man with his head down (maybe after a hit), then he turns and the bearded man comes in. Then they grapple, the bearded man is on the left, they push against each other, then the bald man is behind the bearded man.

Wait, in frame 3: "a shirtless man with a beard and tattoos on his back" (wait, the user's description: the second frame shows the bearded man approaching, frame 3: "the bearded man with tattoos on his back" then frame 4: they are in a clinch.

Wait, the provided video description (the user's input) is the video frames:

[0.0]: a shirtless man (bald, face red) in ring, head down.

[1.0]: another shirtless man (bearded) reaches out.

[2.0]: the bald man turns to face the bearded man.

[3.0]: they are grappling, the bearded man is behind the bald man.

[4.0]: the bearded man holds the bald man's arm, then the bald man grabs the bearded man's head.

Wait, the user's video description:

The actual video:

Frame 0: bald, shirtless man with red marks on face, in ring, moving.

Frame 1: he turns, and another shirtless man with beard approaches, punching.

Frame 2: the two men clash, the bearded man punches the bald man.

Frame 3: the bald man pushes the bearded man, then the bearded man holds

Two shirtless male wrestlers are actively engaged in physical combat within a boxing ring, demonstrating discrete, solid object motion through grappling, pushing, and striking actions. Their movements are driven by direct physical interactions and locomotion.

The background elements (ring ropes, ring structure, and distant audience) remain relatively stable with no fluid motion (fire, water, smoke) or significant environmental shifts observed. No uniform background shifting indicative of ambient environmental motion.


A hand with light skin, fingers pressing strings on the fretboard of a light brown wooden guitar, remains stationary across frames. The hand, partially covered by a dark sleeve, is positioned against the guitar's body. The camera maintains a static close-up perspective focused on the hand and guitar, with minimal background visibility.
