RAW CAPTION: Okay, let's see. I need to create a concise caption for this video based on the user's instructions. The video shows two people interacting. First, I should figure out the main subjects. There's a person with a bald head wearing a black and yellow hoodie and another person with long brown hair in a dark jacket and gray pants.

Looking at the timestamps: from 0 to 5 seconds. The video starts with them in a close position. The first frame (0.0s) has the bald person behind the other, maybe holding them. Then at 0.3s, the person with long hair is leaning back. By 1.4s, they're both moving. The bald person seems to be supporting or lifting the other. The person in the dark jacket is holding something, maybe a microphone? Wait, the user says to exclude text recognition, so maybe it's not important. But in frame 1.4s, the long-haired person is still leaning back, and the bald person is in front.

At 2.5s, there's a slight shake in the camera. The bald person's hands are visible. Then at 3.6s, the person in the dark jacket is moving away, and the bald person is looking down. By 4.7s, the bald person is in front, holding the other person's hands.

Wait, the video is rotated 90 degrees clockwise, so maybe the orientation is inverted. The user mentioned that the video is rotated, but the caption should describe the motion as is. So the main subjects are two people, one bald wearing black and yellow, the other with brown hair in dark jacket and gray pants. They're interacting physically, possibly a dance move or a lift. The bald person is holding the other person, maybe supporting them as they lean back. The camera has a slight shake, maybe handheld. The background is dark, so minimal details. The movement is dynamic, with the bald person moving around the other person.

I need to structure the caption chronologically. Start with the initial position, then how they move. Mention their appearance: bald man in black/yellow hoodie, woman with long brown hair in dark jacket. Spatial relationships: the woman is leaning back against the man. Then the man moves to support her, maybe lifting her. The camera moves slightly, maybe tilted. The final part of the video shows the man in front, the woman moving away. Wait, the user says to exclude text and names. So no mention of specific names, just describe their clothes.

Check the rules again: focus on motion and behavior, chronological order. So:

- Start: two people, bald man in black/yellow hoodie holding a woman in dark jacket and gray pants.
- Movement: woman leans back against him, he adjusts his grip, they move together.
- Camera: slightly shaky, maybe handheld, rotated. Wait, the video is rotated 90 degrees, but the caption should describe as per actual video. Wait, the original video might be rotated, but the user provided the frames as rotated. So in the video, the scene is rotated 90 degrees clockwise, so when they say "bald person behind the other", in reality, the frame is rotated, but the description should be as seen in the video. Wait, maybe the user's instruction says "rotated" but in the actual video, the perspective is different.

Wait, the user provided the video frames as rotated, but the task is to describe the video as it appears. The user says the video is "rotated 90 degrees clockwise", so in the original video, the scene is turned 90 degrees. But when captioning, we have to describe what's visible in the frames provided. However, the user's instruction says "DO NOT include any reasoning in the caption tags", so perhaps the rotation is part of the video's presentation.

Wait, but in the example frames, the video is rotated 90 degrees clockwise. So the main subjects: the bald person is on the left side of the frame (but in reality, the frame is rotated), but for the caption, we have to describe the motion as it appears in the given frames.

Wait, maybe the key is that in the video, the two people are in the frame, and the video is rotated. So when writing the caption, we should describe their positions and movements as seen, regardless of rotation. So maybe the bald person is standing behind the other person, lifting them up. The woman has long hair, dark jacket, gray pants. The bald person has a black and yellow hoodie.

The chronological order: starting at 0.0s, they are close, maybe embracing. Then the woman leans back, the man adjusts, they move, possibly a lift or dance move. Then she's supported by him, and he moves forward. Camera is handheld

Two people are moving: one with long hair stands up and gestures, while another person remains seated. Motion is due to voluntary movement (e.g., standing, hand gestures).

Background appears dark and static with no fluid or environmental motion (e.g., fire, water, smoke). No uniform background shifts indicating camera-induced motion.


RAW CAPTION: Okay, let's tackle this video caption request. First, I need to understand what the user is asking for. They want a concise, chronological paragraph describing the video, following specific rules. The key points are focusing on motion and behavior of main subjects in order, describe appearance and number, mention spatial relationships, conclude with camera perspective and movement, keep background minimal, and exclude text or named characters.

Looking at the video frames provided. The first frame shows two people in the water. One is holding a green and white striped board, wearing a red vest and a white helmet. The other person is in a black top and dark shorts, holding a white board. The second frame is similar but maybe the person with the green board is moving. Then the next frames show a woman standing on a white surfboard, assisted by a man in a white shirt and red shorts. There are other boards in the background.

Wait, the user says to exclude text recognition, so I shouldn't mention the reporter or the text on screen. So ignore the "REPORTA" and the names. Just focus on the visual elements.

Chronicling the sequence: First scene has two people in the water. The person in red vest and helmet is near a green and white board. The other person is holding a white board. Then, the scene changes to the woman on the surfboard with the man helping her. The woman is standing on the white board, the man is kneeling in the water, supporting her. Other boards are in the background.

I need to mention the motion. In the first part, the people might be in the water, maybe preparing to surf. Then the second scene shows the woman stepping onto the board, assisted by the man. So chronological order: first the two people in water with boards, then the woman on the board with the man helping.

Appearance: first person has red vest, white helmet, green/white board. Second person in black top and dark shorts, white board. Then the woman in a bikini top and shorts, standing on white surfboard; man in white shirt, red shorts, kneeling in water.

Spatial relationships: in the first scene, the person with the striped board is next to the other person. In the second scene, the woman is on the board, man is behind her or in front? Wait, the third frame shows the man supporting her from the side. So the man is in the water, holding the board to steady her as she stands.

Background: minimal, just the water and maybe some distant shore, but not much detail needed.

Camera perspective: seems like a medium shot, maybe static? The user says to mention camera movement at the end. The frames show the camera moving slightly maybe? But the problem says to conclude with camera perspective and movement. Let's see, the transition between the two scenes—first two frames are one scene, then the next scene. The camera might pan or cut. Wait, the user says "conclude with the camera perspective and movement". So maybe the camera is static in each scene, but the transition is a cut.

Wait, the rules say: "conclude with the camera perspective and movement (e.g., top-down, pan left, slight shake)." So for the final caption, need to state the camera's perspective (like medium shot) and any movement. Since it's a video, maybe the camera is stationary in both scenes, but the transitions are cuts. But the user probably expects a brief mention.

Putting it all together:

In the initial frames, two individuals stand in shallow water. One wears a red life vest and white helmet, holding a large green-and-white striped board, while the other, in a black top and dark shorts, grips a white board. The scene transitions to a woman in a bikini standing on a white surfboard, assisted by a man in a white shirt and red shorts who kneels beside her in the water. Other surfboards float nearby. The camera maintains a medium perspective with minimal movement between cuts.

Wait, but the user says to mention spatial relationships. In the first scene, the person with the striped board is next to the other person. Maybe the striped board is in front of the person, or they're both in the water. Need to check.

Also, in the third frame, the woman is standing on the board, and the man is behind her, helping her balance. So the man is slightly behind the woman, kneeling.

Also, the second part: the man is supporting her as she stands. So his hands are on the board or her legs?

The rules say to be concise. So maybe:

Two people stand in shallow water, one holding a green-and-white striped board while the other grips a white board. A woman steps onto a white surfboard, assisted by a kneeling man in a white shirt and red shorts. Other boards float in the background. The camera remains stationary with a medium shot

Discrete objects include two people on a paddleboard (one standing, one assisting), a boat with another person, and multiple paddleboards in the background. These objects exhibit motion from human action (paddling, balancing).

The water and distant horizon show minimal wave motion, but no uniform background shift indicating camera movement. Ambient environmental elements (water) are present but not dominant; the focus is on human activity.


A man in a blue shirt and orange shorts enters from the left on a football field with goalposts under a partly cloudy sky, throws a football toward the goalposts, then turns and walks away; the camera remains stationary throughout.

The man (in blue and red) and the ball/disk are moving. The man runs, throws, and walks; the ball is thrown and flies through the air.

The background (trees, house, goalposts) is stable with no uniform shifting. There is no fluid or environmental motion (fire, water, wind) dominating the scene.


Two men stand side by side in an indoor setting; the man on the left wears a dark suit and the man on the right wears a white shirt, both adjusting their red and dark striped ties while conversing. They pull and tighten their ties, with the left man occasionally glancing toward the right man. The background includes sparse furniture and windows, but the camera remains stationary throughout.

Two men are moving their hands and upper bodies to adjust their ties, representing discrete solid objects in motion due to intentional physical actions.

The background features static indoor elements (shelves, books, window) with no shifting or fluid motion. No fire, water, smoke, or wind is present.


A man in an orange vest and black pants ascends a tall ladder positioned against a slender tree with green foliage, holding a chainsaw and adjusting his stance while climbing. He remains on the left side of the tree, with another leafy tree visible to the right, against a clear blue sky. The camera maintains a steady low-angle perspective, focusing on his upward movement.

A single person (discrete object) in a tree, actively moving arms and body while operating a chainsaw (cutting motion).

The background (clear sky and trees) shows no shifting or fluid motion; trees are static with no significant wind-induced sway. No fire, water, or smoke observed.


A person in a blue zip-up jacket raises both hands to their head, then lowers them while holding a small object, subsequently gesturing with the object in their hands. A white vase with white flowers stands to the right. The camera remains stationary.

The person (wearing blue shirt) performs discrete hand movements: adjusting hair, gesturing with both hands, and manipulating a small solid object (likely a ball or stress toy). The object's motion is clearly driven by the person's physical actions.

The background (wall and vase with flowers) shows no shifting or environmental fluid motion; all elements remain static throughout the clip.


RAW CAPTION: Okay, let's see. I need to generate a concise chronological paragraph describing the video based on the provided frames. The user is an expert video captioner, so I have to follow the rules strictly.

First, the main subject is a person wearing a black polo shirt with "GATEWAY" on it. They're in a room with some background elements like a TV and green bottles. The video starts with the person sticking out their tongue, then moving their mouth as if speaking. They point to the right with their right hand. The camera is close-up, slightly shaky, and stays focused on the person. The background has a TV showing green bottles and a metallic object.

I need to focus on motion and behavior in chronological order. Start with the person sticking out tongue, then closing mouth, pointing right. Mention appearance: black polo, brown hair. Spatial relationships: TV in background. Camera perspective is close-up, slight shake. Background minimal. Don't mention text or names.

Wait, the rules say exclude text recognition, so don't mention "GATEWAY" explicitly. Hmm, but the user says "exclude text recognition, named characters, or stylistic analysis." So since the text is on the shirt, but the rule says exclude it. So maybe just describe the shirt as black polo without the text.

Wait, the instruction says "exclude text recognition" which probably means not to mention the text on the shirt. So the shirt is a black polo, but no text.

Also, the background elements: the TV and green bottles. But keep background descriptions minimal. So mention TV with green bottles in the background.

Chronological order: first sticking tongue out, then moving mouth, pointing right.

So the caption should start with the person sticking tongue out, then closing mouth and speaking, then pointing to the right. The camera is close-up, slight shake.

Check rules again: a) motion and behavior in order. b) appearance and number. c) spatial relationships. d) camera perspective and movement. e) minimal background. f) exclude text, names, style.

So:

A person with shoulder-length brown hair, wearing a black polo shirt, initially sticks out their tongue while facing the camera. They then close their mouth and speak, followed by pointing their right hand to the right. The background includes a television displaying green bottles and a metallic object. The camera maintains a close-up perspective with slight movement throughout.

Wait, but the rules say "briefly describe their appearance and number (color, size, orientation)". So maybe "a person with shoulder-length brown hair" is okay. Size isn't specified, but maybe "medium build" but since it's not in the frames, maybe just say person. The rules say "briefly describe", so maybe just mention the shirt color.

Wait, the person is wearing a black polo shirt. So "a person in a black polo shirt" is part of their appearance.

In the video, the person starts by sticking out tongue, then speaks, then points right. The background has a TV with green bottles and a metallic object.

Camera is close-up, slight shake. Background minimal unless essential. So the TV and bottles are part of the background.

Check if "metallic object" is necessary. The original frames mention "a metallic object" next to the TV. Maybe "a metallic object to the right of the TV".

Wait, the first frame shows the person in front of a TV, which has green bottles on it. Then there's a metallic object behind or next to the TV. The person is positioned in front of the TV.

So the spatial relationship: the person is in front of a television displaying green bottles, with a metallic object visible to the right.

But need to keep it minimal. So "background includes a television with green bottles and a metallic object."

Putting it all together:

A person with shoulder-length brown hair, wearing a black polo shirt, sticks out their tongue and then closes their mouth while speaking. They point their right hand to the right. The person is positioned in front of a television showing green bottles and a metallic object. The camera maintains a close-up perspective with slight movement.

Wait, the instructions say "exclude text recognition", so not mentioning the "GATEWAY" text on the shirt. So the shirt is just black polo, no text.

Also, check if "pointing their right hand to the right" is correct. The person points to the right, so direction is right.

Let me check the exact frames: the person's right hand is pointed to the right. So "points right hand towards the right".

But "pointing their right hand to the right" is okay.

Now, check if the background is necessary. The rules say "keep background descriptions minimal unless essential for understanding motion." Since the TV and bottles are part of the setting but not directly related to the person's actions, but maybe they are part of

A person (wearing a black polo shirt) is moving: speaking with facial expressions and making hand gestures (pointing).

The background (bottles and bar setup) is static and shows no shifting or fluid motion (fire, water, smoke, wind).


A person wearing a white headscarf and black top applies a white creamy mask to their face using wet fingertips, spreading it across the cheeks, forehead, and chin. They then hold a metallic container near their face after completing the application. The camera remains stationary in a close-up shot, focusing on the face and upper body with shelves of skincare products visible in the background.

The person's hands and face are moving as they apply the face mask. This movement is solid and distinct, driven by the person's own locomotion.

The background (shelves with skincare products) is static and shows no shifting. There is no fluid or environmental motion (fire, water, wind, etc.).


A small child in a red shirt and blue pants walks toward the camera holding a broom, then turns left and moves past a seated person on a green bench. The camera remains stationary with slight shake.

A boy in a red shirt and jeans sweeps the floor with a broom, moving around the area. Two seated individuals on a green bench show minimal movement.

The background (metal gate, tiled floor, green bench, walls) shows no uniform shifting. No fire, water, smoke, or wind are visible.


RAW CAPTION: Okay, let's tackle this video captioning task. First, I need to understand the user's requirements. They want a concise, chronological paragraph describing the video, following specific rules. Let me go through the rules again to make sure I don't miss anything.

Rule a: Focus on motion and behavior of main subjects in chronological order. So I need to list the actions step by step as they happen in the video.

Rule b: Briefly describe appearance and number. The main subjects here are a man and a woman. The man is in a gray suit with a dark shirt, the woman is in a black dress. Need to mention their colors and maybe sizes, but since it's a video, maybe just the key details.

Rule c: Mention spatial relationships. Like who is in front of whom, left/right positions. In the first frame, the man is adjusting the woman's dress. Then she hugs him. Then he's kneeling, maybe?

Rule d: Conclude with camera perspective and movement. The video starts with a close-up, then maybe a pan or tilt. The first shot is close-up of hands, then a close-up of her hugging, then a wider shot of them in the garden.

Rule e: Minimal background unless essential. The background seems to be a garden with trees and greenery. But maybe just mention it's outdoors if necessary.

Rule f: Exclude text, named characters, stylistic analysis. So no mentioning of names or anything like that.

Looking at the video frames:

Frame 0: Close-up of the man in gray suit adjusting the woman's dress. She's in black. Her hands are visible, maybe holding his hands.

Frame 1: Close-up of the woman embracing the man from behind. Her hand is on his shoulder. Her nails are painted red.

Frame 2: Similar to frame 1, but maybe slightly different angle. She's still hugging him.

Frame 3: Wider shot. Man is on his knees, woman standing. He's holding her hands, she's looking down.

Frame 4: The man is now standing, facing the woman who's looking at him. He's still in the gray suit, she in black.

Wait, the timestamps are 0 to 5 seconds. The frames given are up to frame 5. Let me check the user's input again.

The user provided five frames labeled as [0.0], [1.4], [2.5], [3.6], [4.7]. So each frame is a different moment in the sequence.

Frame 0: Close-up of the man in gray suit adjusting the woman's dress. She's in black. His hands are on her dress.

Frame 1: Close-up of the woman embracing the man from behind. Her hand on his shoulder, red nails.

Frame 2: Same as frame 1, but maybe shifted.

Frame 3: Wider shot. Man on his knees, woman standing. She's holding his hands, maybe he's proposing?

Frame 4: Man is standing, facing her. She's looking down at him.

Wait, in frame 3, the man is on his knees, which suggests a proposal. Then frame 4, he's standing, so maybe he got up after proposing.

Wait, the sequence: Start with close-up of hands (man adjusting dress), then her hugging him, then him kneeling (proposal), then she's standing facing him.

So chronological order:

1. Man in gray suit adjusts woman's black dress (close-up of hands).

2. Woman embraces man from behind, hand on his shoulder (close-up of her arm and shoulder).

3. Wider shot: man kneels, woman stands facing him, he holds her hands.

4. Man stands up, woman looks at him.

Wait, but in the frames provided:

Frame 0: close-up of hands.

Frame 1: woman hugging man.

Frame 2: same hug but maybe from a different angle.

Frame 3: man kneeling, woman standing.

Frame 4: man standing, woman looking down.

Wait, maybe frame 3 shows the man kneeling and holding her hands, then frame 4 he stands up.

But the user's example output needs to be in chronological order.

So the sequence is:

- Close-up of man adjusting woman's dress (0.0s).

- Close-up of woman hugging man (1.4s).

- Man on his knees, woman standing (3.6s).

- Man standing, woman looking at him (4.7s).

Wait, maybe frame 3 is the wider shot where the man is on his knees, and frame 4 shows him standing. So the action is: man adjusts dress, woman hugs, man proposes (kneeling), then stands up.

Wait, the third frame (3.6s) is

Two people (a man and a woman) are interacting: holding hands, embracing, and the man is kneeling. Their movements are subtle but due to their own actions (e.g., adjusting positions, emotional gestures).

No significant fluid or environmental motion (fire, water, smoke, wind). Background (trees, foliage) appears static and shows no uniform shifting.


RAW CAPTION: Got it, let's break down the video. First scene: sky with clouds, then cut to a person in a park. The person is wearing a black jacket, blue shirt, black pants, no shoes. They're throwing something up, then do a backbend. The background has houses, grass, cars. Need to describe the sequence.

Start with the opening: clear blue sky with clouds. Then transition to the person in the park. Chronological: person stands, arms up, throws (maybe a ball?), then does a backbend to the ground. The yellow ball is on the ground near them. Background: residential area, grassy field, houses, parked cars. Camera starts with sky, then follows the person's movement. Camera movement: probably static or slight follow as the person moves.

Make sure to mention main subject's actions step by step. Appearance: black jacket, blue shirt, black pants, barefoot. Spatial: in a grassy park, houses in background. Conclude with camera: starts with sky, then follows the person's motion, probably handheld with slight shake? Wait, the video starts with sky, then cuts to the person. So first shot is sky (0-0.3s), then the person's actions.

So the caption should be:

The video opens with a clear blue sky and scattered clouds. A barefoot person wearing a black jacket, blue shirt, and black pants stands on a grassy park area. They raise both arms upward, then execute a backbend, bending backward with their hands touching the ground while a yellow ball lies on the grass nearby. The background features a residential neighborhood with houses, trees, and parked cars. The camera remains mostly static, capturing the person's movements from a ground-level perspective.

Wait, check rules: chronological, motion of main subjects. First, sky scene (0.0-0.3s), then the person. So the opening shot is sky, then the person starts. So the caption should start with the sky as the initial frame, then move to the person's actions.

Wait, the video starts at [0.0], which is the sky. Then [0.3] is the person. So the first part is sky, then cuts to person.

So caption:

The video begins with a clear blue sky and scattered clouds. The scene transitions to a barefoot individual wearing a black jacket, blue shirt, and black pants performing a sequence in a grassy park. The person raises both arms upward, then executes a backbend, bending backward with their hands reaching toward the ground as a yellow ball remains on the grass nearby. Houses, trees, and parked cars form the background. The camera captures the actions from a fixed ground-level perspective with minimal movement.

Check rules: a) chronological order—sky first, then person's actions. b) appearance: black jacket, blue shirt, black pants, barefoot. c) spatial: grassy park, yellow ball on grass, houses in background. d) conclude with camera: fixed ground-level, minimal movement. e) background minimal—so houses, trees, cars are brief. f) no text, names. g) internal thought, but output as required.

Let's check each rule:

a) Motion: sky (static), then person's actions (raise arms, backbend). Yes, chronological.

b) Appearance: main subject's clothes, barefoot. Correct.

c) Spatial: grassy park, yellow ball nearby, background houses. Included.

d) Camera: ground-level, fixed (or minimal movement). Correct.

e) Background minimal—yes, just enough to set the scene.

f) Excluded text, names. Correct.

So the caption should be concise. Let's make it tight.

"The video opens with a clear blue sky and scattered clouds. A barefoot person in a black jacket, blue shirt, and black pants stands on a grassy park area, raises both arms upward, then performs a backbend, bending backward with hands toward the ground as a yellow ball lies on the grass nearby. The background includes houses and parked cars. The camera remains fixed at ground level, capturing the sequence with minimal movement."

Wait, the transition is from sky to person. The first frame is sky, then the next frames are the person. So in the caption, mention the opening with sky, then transition to person.

Alternative:

"The video starts with a clear blue sky and scattered clouds, then cuts to a barefoot individual wearing a black jacket, blue shirt, and black pants in a grassy park. The person raises both arms upward, executes a backbend, and bends backward with hands reaching the ground while a yellow ball rests on the grass. Houses and parked cars appear in the background. The camera maintains a ground-level perspective with slight static movement."

Wait, "slight static movement"—but maybe the camera is

A person is performing a series of movements: initially standing with arms raised, then walking, and finally executing a handstand (including a back handspring). The person's motion is due to physical locomotion and gymnastic maneuvers.

The background (houses, trees, car) is static with no significant shifting. No fluid/environmental motion (fire, water, smoke) or wind-induced tree movement is dominant.


A person in a dark blue shirt, black shorts, and white shoes runs across a grassy field toward the camera while holding a white frisbee, moving from the background to the foreground. The individual maintains the frisbee in their right hand throughout the motion. The camera remains stationary with a slight shake.

A person (wearing dark clothing and white shoes) is moving across the field, running and throwing a white frisbee. The frisbee's trajectory is clearly visible after release.

The background (trees, buildings, distant structures) shows no significant shifting or fluid motion; no fire, water, smoke, or wind-driven elements are present. Background elements remain static relative to the ground plane.


Three individuals in white karate uniforms with brown and black belts interact on a red mat. The central figure (brown belt) steps forward, advancing toward the individual to their left (black belt), while the person to the right (black belt, striped pants) holds a wooden board. Spectators stand in the background, observing the scene. The camera remains stationary, capturing the action from a fixed medium perspective.

Two karate practitioners in white uniforms with black belts are engaged in combat. Their motion involves kicking, blocking, and shifting positions, driven by physical forces (muscle movement, impact). Additional static observers are present but not moving significantly.

The background consists of stationary walls, red/blue mats, and spectators. No fluid motion (fire, water, smoke) or significant environmental sway is present. Background elements show minimal uniform displacement, indicating a stable environment.


A person in blue attire rides a large dark gray elephant along a dirt path, the elephant walking forward with its trunk extended downward; as the video progresses, the rider shifts position slightly while the elephant continues moving, with another dark elephant appearing in the background to the left; the camera follows the main elephant in a steady tracking shot.

Elephant and rider are discrete solid objects moving due to locomotion (walking). The elephant's movement is the primary object motion, with the rider remaining seated.

Background consists of stationary trees and ground with no fluid motion (fire, water, smoke, or wind). No significant ambient environmental motion detected.


A person's arm, clad in a light purple long-sleeve shirt, moves a brown rectangular object across a white tiled floor in a sliding motion, shifting the object from left to right and adjusting its position. The camera maintains a close-up perspective focused on the arm and object, capturing the motion against the tiled background.

A person (only legs and hand visible) is moving their hand and foot in a repetitive wiping motion on the floor.

The background (tiled floor) is static with no fluid or environmental motion. No fire, water, smoke, or wind observed.


RAW CAPTION: Got it, let's tackle this. The task is to generate a concise chronological paragraph describing the video. First, I need to watch the video and note the actions.

The video starts with a woman in a yellow dress. She's adjusting her hair, using both hands. Then she moves her arms down, maybe sitting down? Then she turns to the side, extending her right arm. Wait, the frames: first, she's holding her hair, then arms down, then she turns to the right, maybe pointing or gesturing.

Let's check the details. She's wearing a yellow top, long hair, a necklace. Background has wooden paneling, a door, maybe a chair.

Chronological order:

1. She raises both hands to adjust her hair, then lowers arms, turning her body to the right, extending her right arm.

Wait, in frame 0, she's raising hands to hair. Then frame 1, still adjusting. Frame 2, she's lowering arms, maybe sitting? Then frame 3-4, she's turning to the right, arm extended.

So the sequence: starts by adjusting hair with both hands, then lowers hands and turns her head/upper body to the right, extending her right arm.

Appearance: woman with long dark hair, wearing a yellow spaghetti strap top, necklace. Background: wooden paneling, door, chair.

Spatial relationships: in front of the wooden paneling, door behind her.

Camera perspective: starts with medium shot, then maybe a slight pan to the right as she moves.

Wait, need to describe motion chronologically.

So step by step:

- The woman, dressed in a yellow spaghetti strap top and wearing a necklace, begins by adjusting her hair with both hands raised. She then lowers her arms and turns her head and upper body to the right, extending her right arm outward.

Check the rules: focus on motion, chronological. Mention appearance (color, size, orientation): yellow top, long hair, necklace. Spatial: in front of wooden paneling. Camera: starts with medium shot, maybe camera moves slightly to follow her turn.

Wait, the problem says "conclude with the camera perspective and movement". So need to mention that at the end.

Let me structure:

A woman with long dark hair, wearing a yellow top and necklace, adjusts her hair with both hands raised near her head. She lowers her arms, turns her upper body to the right, and extends her right arm outward. The scene occurs in front of wooden paneling with a door visible in the background. The camera remains steady, capturing a medium shot of her movements.

Wait, but need to be concise. Let's check the exact steps.

First action: hands to hair. Then lowers hands, turns to right, extends arm.

Appearance: woman (gender not specified, but main subject), yellow top, long hair, necklace.

Spatial: in front of wooden walls, door behind.

Camera: starts as medium shot, then maybe no major movement. Wait, the video description might have camera movement. The user's example says "camera perspective and movement". Let's see the frames: from frame 0 to 4, the camera might have panned right as she moves.

Wait, in the video, when she turns, the camera might follow. So "the camera slightly pans to follow her movement".

Now, put it all together:

A woman with long dark hair, wearing a yellow spaghetti strap top and a necklace, adjusts her hair with both hands raised above her head. She then lowers her arms, turns her upper body to the right, and extends her right arm outward. The scene is set against wooden paneling with a door visible in the background. The camera maintains a medium shot and slightly pans right to follow her motion.

Check the rules: exclude text, named characters, etc. Don't mention the door being brown, etc., but since it's part of background, maybe minimal.

Wait, the rules say "background descriptions minimal unless essential for understanding motion". Since the door is part of the background, but maybe not essential for motion. So maybe just "wooden paneling" as the background.

Wait, in frame 0, there's a wooden wall, a chair to the left. So background: wooden paneling, a chair visible on the left. But "minimal unless essential". If the chair isn't relevant for motion, maybe omit. So focus on the action.

Let me revise:

A woman with long dark hair, wearing a yellow top and a necklace, raises both hands to adjust her hair. She then lowers her hands, turns her upper body to the right, and extends her right arm. The background features wooden paneling. The camera remains steady in a medium shot throughout, capturing her movements.

Wait, but in the video, she moves her arm to

The woman in the yellow top is moving her arms, head, and body; her gestures and adjustments are the discrete solid object motion.

The background (wooden panels and wall) is static and does not show fluid or environmental motion. There is no fire, water, smoke, or wind.


A woman wearing a white hard hat, brown jacket, and yellow vest stands holding a clipboard. She looks at the clipboard, then turns her head to the right and gestures with her right hand toward a yellow and black survey device mounted on an orange tripod positioned to her left. The background includes a grassy area with a building. The camera remains stationary throughout the sequence.

Discrete solid objects: A person (Katie) is moving her head and arms while interacting with a surveying device on a tripod.

Background elements (grass, construction structures) are static with no uniform shifting; no fire, water, smoke, or wind visible.


A person wearing a dark blue shirt and red pants sits and plays an orange electric bass guitar. They lift their head briefly before leaning forward, bringing the instrument close to the camera to focus on the bass's body and strings. The camera remains stationary but captures the transition to a close-up view as the guitar moves toward the lens.

The person and bass guitar move intentionally: hands pluck strings, body shifts position, and the guitar is tilted toward the camera for demonstration.

The background (room walls, cabinet, boxes) remains static with no uniform shifting or environmental motion (fire, water, smoke, wind). No fluid dynamics observed.


RAW CAPTION: Okay, let me try to figure this out. The user wants me to act as an expert video captioner. My task is to generate a concise, chronological paragraph describing the provided video based on the given rules.

First, I need to look at the video frames. The video shows a girl in a swimming pool. She's wearing a black swimsuit. The first frame has her with her hands covering her mouth, then she looks up and smiles. Then she moves her hands, maybe waving or gesturing, and then she lowers her hands again. The background has poolside elements like tiles and maybe some pool toys.

Rule a says to focus on motion and behavior in chronological order. So I need to describe each action step by step. The girl starts with hands over mouth, then she looks up and smiles, then moves her hands, then lowers them again. Maybe she's splashing water or moving her arms.

Rule b: mention appearance and number. She's a girl, wearing a black swimsuit, so color and size (but size might be subjective, but since it's a video, maybe just note she's a person in the pool). The number is one person.

Rule c: spatial relationships. She's in the pool, maybe near the edge. The background has the pool tiles and maybe some objects, but minimal description as per rule e.

Rule d: camera perspective. The camera seems to be at water level, maybe slightly above, but not sure. It's a fixed camera, maybe no movement, just capturing her actions.

Rule e: minimal background. So mention the pool and maybe the edge, but not too much.

Rule f: exclude text and named characters, which is okay here.

Putting it all together: chronological order. Start with hands over mouth, then she lifts hands, smiles, moves arms, then lowers hands again. Camera is static, close-up on her.

Wait, the first frame shows her with hands covering mouth, then she looks up, smiles, maybe waves, then moves her hands to the sides, then back to mouth. Need to check the timestamps.

Frame 0: hands on mouth. Frame 1: hands on mouth. Frame 2: hands moving up, smiling. Frame 3: hands open, maybe waving. Frame 4: hands moving, maybe splashing. Frame 5: hands to mouth again.

So the sequence is: she covers her mouth, looks up, smiles, moves her arms, then brings hands back to mouth. The description should be in order.

Also, the camera is probably static, as there's no mention of panning or moving. The background is the pool edge, so "pool edge" is minimal.

Avoid mentioning text or names. The girl's appearance: swimsuit is black, medium-length hair maybe, but rules say focus on motion. Maybe just mention she's a person in a pool.

So the caption should be something like: A girl in a black swimsuit is in a pool, initially covering her mouth with both hands. She then lifts her hands, smiles, and moves her arms outward in a gesture. She lowers her arms back toward the water, briefly touching it before returning to a position with hands near her mouth. The camera remains static, capturing her upper body from a slightly elevated angle, with the pool edge visible in the background.

Wait, need to check if the camera is elevated. The first frame shows her in the water up to her shoulders, so camera is likely at water level. Maybe "from a water level perspective" but the rules say "camera perspective and movement". Maybe "static close-up" as per the frames given.

Also, the background is minimal, so just the pool edge. Let me make sure to keep it concise. Let's see:

"A girl in a black swimsuit is in a swimming pool, initially holding both hands over her mouth. She then lifts her hands, smiles, and moves her arms outward before bringing them back to the water. The camera remains static, capturing her upper body against the pool's tiled edge."

Hmm, but need to check if "brings them back to the water" is accurate. The fifth frame shows her hands near her mouth again, so maybe "returning to a position with hands near her mouth".

Also, check the order: start with hands on mouth (0.0), then in frame 1 she's still holding, frame 2 she lifts hands and smiles, then frame 3 moves arms, frame 4 maybe moving hands again, frame 5 back to mouth.

Wait, the video starts at [0.0] with her hands covering mouth, then [0.3] same, [1.4] she's lifting hands, maybe smiling, then [2.5] she's moving arms, [3.6] more movement, [4.7] back to mouth.

So sequence is: covers mouth →

A girl (solid, distinct object) is swimming, moving her arms, head, and body through the water.

The pool water shows motion due to the girl's swimming, but the background (pool edge and tiles) is static and does not shift uniformly. The dominant motion is the girl's locomotion.


A man in a black sleeveless top and black shorts stands inside a netted throwing cage, facing away from the camera. He raises both arms, then rotates his body while extending his right arm forward to release a discus. The background features a grassy field and scattered trees under a partly cloudy sky. The camera remains stationary, capturing the motion through the netted enclosure.

The person is moving in a rotational manner while preparing to throw the discus, indicating locomotion and throwing motion.

No shifting background or fluid/environmental motion observed. Background elements (net, grass, trees) are static.


A hand holding a blue brush draws a smooth curved line on a brown surface, completing the stroke with fluid motion and lifting the brush away; the camera maintains a static top-down perspective.

The background is a static brown surface with no shifting or fluid motion (e.g., fire, water, smoke).


A hand holds a green-rinded watermelon half with bright red flesh, positioned above a speckled countertop. To the left, a clear container holds pre-cut watermelon pieces. The hand rotates the watermelon, then uses a knife to slice it into triangular sections, causing pieces to fall onto the counter. The camera remains stationary in a top-down perspective throughout, capturing the motion against a backdrop of minimal kitchen items.

A hand moves and interacts with a watermelon (cutting and scooping pieces), demonstrating explicit physical forces on solid objects.

Static background elements (countertop, container, bottle) show no uniform shifting or fluid motion; no fire, water, smoke, or wind detected.


A woman with long blonde hair, wearing glasses and a patterned short dress, sits in a room with red chairs and music stands. She holds a large brown double bass, moving her left hand along the neck to press strings while drawing a bow across the strings in a rhythmic motion.

A hand enters the frame, holding a white sheet of paper, and inserts it into the open slot of a black paper shredder. The hand then withdraws, revealing the shredded paper inside the device. The camera remains stationary, focused on the shredder from a top-down angle, with the desk and chair visible in the background.

A hand is inserting paper into a shredder, and the paper is moving through the shredder's input slot. The hand and paper are the only discrete objects showing motion.

The background (desk and stacked papers) is static; no fluid or wind motion observed.


A man in a maroon shirt and beige pants and a woman in a black top and maroon skirt dance in a room with red walls and wooden flooring. They begin by holding hands, then spin and step around each other in a circular motion, altering their positions as they move. The camera remains stationary, capturing their movements from a fixed perspective.

Two people (a man in a maroon shirt and beige pants, a woman in a black top and red skirt) are dancing. Their motion is coordinated, involving stepping, turning, and hand movements, clearly driven by their own locomotion without external environmental influences.

The background (red walls, wooden floor, windows, door, framed pictures) shows no shifting or fluid motion; static elements remain uniformly fixed throughout the video, indicating no environmental forces like wind or smoke.


A boy in a yellow shirt sits in front of the camera, initially smiling with his mouth open. He then raises his right hand toward the camera, making a gesture with his fingers. The camera remains static, focusing closely on the boy against a minimal background of a cabinet and wall.

A person's hands are moving in discrete gestures (e.g., finger movements, waving), indicating intentional motion of solid objects.

Static background elements (shelves, containers) show no uniform shifting; no fire, water, or wind-driven motion observed.


RAW CAPTION: Got it, let's tackle this. First, I need to describe the video in chronological order. The main subject is a person using a tool on an object. Let's see the frames. The person has hands, one in black sleeve, the other maybe a different sleeve? Wait, the video shows hands working with a cylindrical object, maybe a metal part. The tool looks like a rod or a screwdriver. The person is holding the tool and the object, twisting or turning.

First frame: hands manipulating the tool on the object. Then the action continues. The person's hands are in the center, the tool is being used. The background has a gray surface, maybe concrete, and some equipment. But per the rules, background should be minimal unless essential.

Chronologically: The person (hands visible, one black sleeve, one maybe light) holds a long, metallic tool (cylindrical, shiny) and uses it on a smaller cylindrical object (dark, maybe black or dark metal). They twist the tool, applying force. The action repeats: hands move, tool turns, object is adjusted.

Spatial: The hands are in the foreground, the tool is held vertically or horizontally? The object being worked on is on a surface. The person's arms are visible.

Camera perspective: close-up, focusing on the hands and the tool, so it's a close-up shot. No movement mentioned, so static or slight shake? The description says "slight shake" if applicable. Wait, the video might be a close-up with slight movement.

Putting it all together:

A pair of hands, one in a black sleeve and the other in a light sleeve, manipulates a long metallic tool against a dark cylindrical object. The hands twist the tool repeatedly, applying force to the object. The action occurs on a gray surface with mechanical components in the background. The camera maintains a close-up perspective, focusing on the hands and tool, with minimal movement.

Wait, check the rules. Need to be concise, chronological. Let's see:

- Start: hands holding tool and object, begin twisting.
- Continues: repeated twisting motion.
- Background: minimal, mention only if essential. The background has concrete and maybe some equipment, but maybe too much. The rules say "minimal unless essential". Since the main action is hands and tool, background can be brief.

So, "A person uses a long metallic tool to twist a dark cylindrical object; hands, one in black sleeve and the other in light, manipulate the tool in a repetitive motion, applying force to the object. The camera captures a close-up view of the hands and tool with slight movement, focusing on the interaction."

Wait, need to be concise. Let's check the example.

Another approach:

The video shows a pair of hands (one in black, one in light-colored sleeve) using a metallic tool to work on a dark cylindrical object. The hands repeatedly twist the tool, applying force to the object. The camera remains in a close-up perspective, focusing on the hands and tool with minimal movement.

Check the rules: chronological order, motion, behavior. Yes, the hands twist the tool repeatedly, that's the main motion. The appearance of hands: one black sleeve, one light. The object is dark cylindrical.

Background: maybe gray concrete, but minimal. So include if essential. The object is on a surface, but maybe not necessary. Wait, the video shows "gray surface" and "mechanical components", but per rule e, keep background minimal. So maybe just "gray surface" as minimal.

Wait, the first frame shows the hands, tool, and a gray surface. So "The person's hands (one in black sleeve, the other in light sleeve) manipulate a metallic tool against a dark cylindrical object on a gray surface, twisting the tool in a repetitive motion. The camera maintains a close-up focus on the hands and tool, with slight movement."

But need to be concise. Let's make it shorter.

"A person's hands (one in black sleeve, the other in light sleeve) use a metallic tool to twist a dark cylindrical object. The hands repeatedly apply force, rotating the tool in a clockwise motion. The camera captures a close-up view of the interaction with minimal movement."

Wait, but the problem says "consecutive frames" so the motion is in sequence. The video has 5 frames, each showing the twisting action. So the chronological order is the hands moving the tool back and forth, twisting.

Let me check the frames:

Frame 0: hands holding tool and object, tool is being turned.

Frame 1: tool is turned further.

Frame 2: hands adjusting, tool is in position.

Frame 3: tool is twisted again.

Frame 4: continues.

So the main action is the hands repeatedly twisting the tool to turn the object.

Final caption:

He moves the pointer across the map, shifting it from the top right to the bottom left regions. The boy’s body remains mostly stationary while his arm gestures toward various sections of the map. The background includes shelves with office supplies, but the focus stays on the boy and the map. The camera maintains a steady, close-up perspective without significant movement.

The boy (in red shirt) moves his pointer and hand to point at different states on the map of the United States; the pointer is a discrete solid object moving due to the boy's arm movement.

The background (wall and charts) is static with no shifting or environmental motion (fire, water, wind).


A child in a black-and-white striped shirt plays a large outdoor xylophone, initially shown from a low angle focusing on their legs and hands striking the instrument. The camera pans upward to reveal the child’s full body as they continue playing, with a woman in a yellow shirt and a man in a green shirt standing nearby observing. The camera shifts to include the instrument’s extended length and the surrounding street, where cars pass and mountains are visible in the background. The perspective transitions from close-up to a wider view, maintaining smooth motion throughout.

The child's hands actively press organ pipes (explicit physical interaction). Background pedestrians and vehicles move independently due to locomotion (e.g., woman in yellow walking, man in black moving through frame).

RAW CAPTION: Okay, let's tackle this video captioning task. The user wants a concise, chronological paragraph following specific rules. First, I need to identify the main subject. The video shows a person operating a snow blower. The person is wearing a beige jacket and a hat, so I should mention their appearance briefly.

Looking at the motion: the snow blower is moving through snow, kicking up a lot of snow. The sequence starts with the person in the center, then moving forward. The snow blower is black with red parts, maybe. They're clearing a path, so the direction is important—moving from right to left or left to right? The video frames show the person moving forward, so the motion is forward through the snow.

Spatial relationships: the person is in front of the snow blower, which is pushing snow to the sides. The background has trees, but the rules say minimal background unless essential. Since the main action is the snow blowing, maybe just mention the trees are in the background without details.

Camera perspective: the video seems to be a steady shot, possibly following the person. The user says camera movement like pan left or slight shake. The description mentions "slight shake" in the rules, but in the video, it might be a fixed shot. Wait, the frames change positions a bit, but maybe it's a handheld camera with slight movement.

Wait, the rules say to conclude with camera perspective and movement. The example in the problem says "slight shake," so if the video has a bit of movement, I need to note that.

Putting it all together: Person in beige jacket and hat operating a black snow blower with red elements, moving forward through deep snow, blowing snow to sides. The camera follows the motion with slight shake, background has trees but minimal description.

Check the rules: chronological order. So start with the person operating the blower, moving forward, snow being expelled. Mention the person's appearance (beige jacket, hat), the snow blower's color (black, red), motion (forward), snow kicked up. Then camera movement.

Wait, the first frame shows the person in the center, then moving left. So maybe the direction is leftward. The video might be panning left as the person moves. But the user's rules say "conclude with camera perspective and movement." The example in the problem might have a "slight shake," but in this case, maybe it's a steady follow shot.

Wait, the user says "DO NOT include any reasoning in the caption tags," so just stick to the facts. Let's make sure to not mention background unless essential. The trees are in the background but maybe not essential for understanding motion, so maybe just say "trees in background" briefly.

Wait, rule e says minimal background unless essential. Since the person is moving through snow, trees are part of the setting but maybe not needed. Hmm. Maybe just omit the trees.

Wait, the video has snow on both sides, so the person is clearing a path between snowbanks. So the spatial relationship is the person between snowbanks, moving forward.

Let me structure it:

A person wearing a beige jacket and dark hat operates a black snow blower with red components, moving forward through deep snow and ejecting snow to both sides. The snow blower kicks up dense clouds of snow as it progresses along a path bordered by snowbanks. The camera follows the motion with a slight shake, maintaining a frontal perspective of the operator.

Check if all rules are followed:

a) Motion in chronological order: person operates blower, moves forward, ejects snow.

b) Appearance: beige jacket, dark hat, blower black with red.

c) Spatial: snowbanks on both sides.

d) Camera: frontal, slight shake.

e) Background minimal: snowbanks and trees not mentioned. Wait, the original video has trees in the background. But the rule says minimal unless essential. Maybe mention "trees in background" but the problem says to keep background descriptions minimal. Since the person is moving through snow, maybe the trees aren't essential. But if the trees are visible, perhaps it's better to include "trees in background" as part of the setting. However, the user's example might not mention it. Let's check the example given in the problem statement.

Wait, the problem's example (though not provided here) but the rules say minimal background. So perhaps omit the trees. The main action is the person using the blower, so background can be just "snow-covered area" but the original video has trees.

Hmm. The video shows trees in the background, but they're not central to the action. So according to rule e, "keep background descriptions minimal unless essential for understanding motion." Since the motion is the person moving through snow, maybe the trees aren't essential. So perhaps no mention of background. But the initial frames show trees

The snow blower (machine) and operator are discrete solid objects moving forward due to the machine's propulsion system.

The background trees remain static; the snow plume from the snow blower is a secondary effect of the machine's operation, not dominant environmental motion (fire, water, smoke, wind).


A group of people in white shirts and dark bottoms move energetically through a bright indoor room. They step forward, turn, and interact with one another, shifting positions dynamically as some advance while others move backward.

tags. So the final answer should be inside those tags. No other text. Make sure it's concise. Let me adjust to be more concise.  "A hand stirs scrambled eggs mixed with bacon in a black frying pan on a stovetop using a wooden spoon. The spoon moves in circular motions to combine the ingredients, with the camera maintaining a top-down view throughout the sequence."  Yes, that's chronological: starts with the hand stirring, the mixture, the spoon action, camera perspective. Kept background minimal (stovetop). Mentioned spatial relationship (pan on stovetop). Motion is circular stirring. Appearance of ingredients (yellow eggs, brown bacon). Hand is the main subject. Camera top-down. Looks good. </think>  <caption_output>A hand stirs scrambled eggs mixed with brown bacon pieces in a black frying pan on a stovetop using a wooden spoon. The spoon moves in circular motions to incorporate the bacon into the yellow egg mixture, with the hand entering from the left side of the frame. The camera maintains a top-down perspective, capturing the stirring action against the pan's surface.

The camera remains stationary during both segments.

In the initial scene, the masseuse's hands are moving to apply pressure to the recipient's back, indicating discrete object physics due to explicit physical interaction.

No significant shifting background or environmental motion (fire, water, smoke, wind). The initial scene features a static blue wall, followed by static book covers on a white background.


Five children in orange jerseys, black shorts, and helmets skate across the ice rink, passing a puck among themselves while one child in a white jersey stands to their right. The orange team moves forward, adjusting positions, as the camera pans slightly left to follow their motion.

Multiple hockey players (in orange and white jerseys) are actively skating and maneuvering on the ice with hockey sticks. Their movements include positional changes, stick handling, and potential puck interaction, all driven by physical locomotion.

The rink boards, advertisements, and spectators remain stationary with no shifting or fluid motion. No fire, water, smoke, or wind-driven effects are present in the environment.


A person wearing a yellow top and gold bangles adjusts an orange saree with green and red stripes, smoothing and securing the fabric's pleats. The individual then steps back to display the fully draped saree against a solid pink backdrop. The camera transitions from a close-up of the hands manipulating the saree to a wider shot capturing the figure in full.

Two people are visible: one is adjusting a saree (moving hands and body), and the other is standing. The motion is due to intentional physical actions.

The background is a solid pink wall with no shifting or environmental motion (e.g., wind, fire).


A person wearing a black shirt and transparent glove sits beside a black car seat, using a tool to scrape its surface. The individual moves the tool across the seat’s material, with small white containers visible on the floor to the left. The camera zooms in to show a close-up of the gloved hand and tool interacting with the seat’s texture, maintaining focus on the scraping motion. Background elements are minimal and stationary.

A gloved hand holding a knife is actively cutting a black leather-like object, demonstrating explicit physical interaction (cutting force).

Background elements (walls, neutral backdrop) are static with no uniform shifting, and there are no fluid/environmental motions (fire, water, smoke, wind) present.


A pair of hands with dark nail polish and a ring flips through a spiral-bound coloring book, revealing a detailed black-and-white floral sketch on a page resting on a grid-patterned surface. The hands then pick up a box of rainbow-colored colored pencils, positioning them above the sketch, and begin coloring the floral design with deliberate strokes. The camera maintains a top-down perspective throughout the sequence.

The hand (with painted nails) is moving to flip pages of a coloring book and manipulate colored pencils. The coloring book and pencil case are also in motion due to hand interaction.

No shifting backgrounds or fluid/environmental motion (fire, water, wind) observed. Background (table surface) is static and consistent throughout the clip.


A person in black shorts and blue flip-flops uses an orange string trimmer to cut grass, then walks leftward across the lawn while the trimmer’s cord trails behind. The camera remains stationary, capturing the motion from a fixed low angle.

A person (legs and feet) is walking and using a red-handled tool to trim the grass. The tool and the person are moving discretely.

No shifting background or fluid/environmental motion (fire, water, wind) detected. Grass is being cut by a tool, but this is not ambient environmental.


A gray cat stands in front of a black printer, pressing its paws against the device and moving its head. A human hand is partially visible to the right, interacting with the printer's controls. The floral-patterned fabric in the background remains static. The camera maintains a top-down perspective with slight movement.

The gloved hand of the person is actively moving to press buttons on the printer and adjust paper placement; the remote control is held and manipulated by the person.

No shifting background or fluid/environmental motion observed. Background elements (floral pattern) are stationary relative to the printer and camera frame.


A performer in a green shirt stands on a stage with red curtains adorned with stars, making subtle movements and gestures throughout the sequence. The audience, visible as dark silhouettes in front of the stage, remains seated. The camera maintains a fixed perspective from the audience's viewpoint, capturing the stage performance without noticeable movement.

Performers on stage are moving (gesturing, possibly walking) due to their physical actions; audience is mostly static with minimal movement.

The background (stage backdrop and structural elements) is static and shows no shifting. There is no fluid or environmental motion (fire, water, smoke, wind) dominant.


A group of musicians in dark formal attire play string instruments; a central cellist in a dark suit moves his bow across the cello's strings, while surrounding violinists and other cellists similarly bow their instruments. The musicians are seated in a concert setting, with the central cellist positioned in front of others, violinists to the left and right. The camera maintains a static perspective throughout.

Musicians (cellist in foreground and others) exhibit discrete hand/arm movements (bowing, fingering) while playing instruments.

Background (architectural columns, arches) is static with no shifting or environmental fluids (fire, water, smoke, wind) observed.


A small child in a black shirt holds an ice cream cone, initially looking at the camera with an open mouth, then brings the cone to their mouth to take a bite, continues eating while holding the cone. The camera remains in a close-up position with slight movement, focusing on the child's actions.

Child (discrete solid object) performing intentional eating motion: hand moving to bring ice cream from cup to mouth, with head tilting and eye movement. Ice cream cup is held steady with minimal displacement.

Static car interior background with no shifting elements, no fire/water/smoke/wind present. Background elements (seat, headrest) remain stationary throughout the clip.


The video opens with a black screen, transitioning to an outdoor scene featuring a grassy area, a dirt mound, a green dumpster, and trees. A bicycle with a rider in gray pants and dark shoes enters from the right, ascends the dirt mound, and moves behind the dumpster. The camera remains stationary.

A dog (solid, distinct object) moves from left to right across the grassy area, exhibiting clear locomotion. This motion is tracked via bounding box shifts and is the only significant discrete object movement.

Background elements (trees, building, grass, concrete path) remain static throughout most of the video. A transient shadow moves across the scene due to the dog's passage, but this is a localized effect from the discrete object and not ambient environmental motion (no wind, fire, water, or smoke observed).


A man in a black shirt, camouflage shorts, and pink gloves stands on a balcony, using a tool to clean a large glass door. He bends down, works on the lower section of the door, then stands upright. The camera remains stationary.

A person is moving, cleaning a window with a cloth, exhibiting locomotion and physical interaction with the window.

Background elements (buildings, plant) show no uniform shifting or fluid motion; no fire, water, smoke, or wind dominates.


RAW CAPTION: Got it, let's break this down. First, the video shows a person using a circular saw. The main subject is the person's hands and the saw. The saw is black with a yellow label, maybe a Craftsman brand. The person is cutting through a piece of stone or concrete, generating dust and debris. The background has rocks and dirt.

Chronological order: The person is holding the saw, moving it to cut. Let's see the frames: first frame shows hands on saw, then the saw is in action, cutting, with dust. The person is wearing dark clothing, maybe jeans. The saw is positioned over the stone, cutting through it.

Need to mention appearance: person's hands (dark sleeves), saw (black, yellow label), stone being cut (gray, large rocks around). Motion: the saw is moving back and forth, cutting the stone, producing dust.

Spatial relationships: The saw is held by the person, positioned over the stone. The person's hands are gripping the saw handles. The stone is on the ground, surrounded by rocks.

Camera perspective: Close-up, focused on the saw and hands. Maybe slight movement as the saw cuts? The video frames show a steady close-up, so probably static or minimal movement.

Background: Rocks and dirt, but keep it minimal. Essential for understanding motion? Maybe the stone being cut is part of the scene.

Exclude text recognition (like "Craftsman" but wait, the rules say exclude text recognition. Wait, the rules say "Exclude text recognition, named characters, or stylistic analysis." So even if the label is visible, don't mention "Craftsman" because that's text recognition. Wait, but the instruction says "exclude text recognition" so we can't mention the brand name. So focus on the color and shape: the saw has a yellow label, but we can say "a black circular saw with a yellow label" but wait, no, text recognition is excluded. Hmm, the problem says "Exclude text recognition", so even if there's text, don't include it. So maybe just describe the saw as black with a yellow sticker, but not the text. Wait, the rule says "Exclude text recognition, named characters, or stylistic analysis." So "Craftsman" is text, so we don't mention it. So just say "a black circular saw with a yellow label" but maybe better to say "a black circular saw featuring a yellow label" but no text, so perhaps the yellow label is just a color detail. Wait, the rule is to exclude text recognition, so we can't reference the actual words on the label, but we can mention the presence of a yellow label as a visual feature. So that's okay.

So putting it all together:

The video shows a person using a black circular saw with a yellow label to cut a large gray stone. The person’s hands, wearing dark sleeves, grip the saw’s handles as it moves forward, generating dust and debris. The stone lies on a rocky ground surrounded by irregular stones. The camera maintains a close-up, steady perspective focused on the saw’s cutting action, capturing the motion of the blade through the stone.

Wait, check the rules: "Focus primarily on the motion and behavior of main subjects (people/animals/objects) in chronological order." So the main subjects are the person's hands, the saw, and the stone. Motion: hands holding the saw, saw cutting the stone. Chronological: starts with the hands positioning the saw, then cutting.

The video is a series of frames showing the saw in action, so the sequence is: hands hold the saw, cut the stone, dust is produced.

Also, "Briefly describe their appearance and number (color, size, orientation)." So the saw is black, the label is yellow (but text excluded, so just yellow label), the stone is gray, the person's hands are dark sleeves.

"Conclude with the camera perspective and movement": the camera is close-up, steady, maybe no movement.

"Keep background descriptions minimal unless essential for understanding motion." Background has rocks and dirt, which is essential as the stone is on rocky ground.

Let me structure the caption:

A person’s hands, clad in dark sleeves, operate a black circular saw with a yellow label, cutting a large gray stone. The saw moves forward through the stone, generating dust and small debris. The stone rests on a rocky surface among other stones. The camera remains close and steady, focusing on the saw’s motion during the cutting process.

Check if all rules are met:

a) Motion in chronological order: hands operating saw, cutting stone.

b) Appearance: hands (dark sleeves), saw (black, yellow label), stone (gray, large).

c) Spatial: hands grip saw, saw over stone, stone on rocky ground.

d) Camera: close-up,

A person holding a cutting tool (saw) is actively sawing through stone, with the tool rotating and moving to cut the material. The person's hands and the saw are discrete solid objects in motion due to physical force applied to the stone.

The background consists of stationary rocks and ground with minimal shifting; no dominant fire, water, or smoke motion observed. Dust from cutting is secondary and not a primary environmental fluid.


A woman in a light blue shirt and white shorts holds a white plate near a black scooter with a red and white seat. She moves the plate into the scooter’s open storage compartment, then turns to her left toward a cart with colorful items. A silver car is parked to the right. The camera remains stationary throughout.

The woman (solid object) moves her hands and body to interact with the motorcycle (adjusting or handling) and the cart (picking up or placing a bottle).

The background (cart, motorcycle, car) is static with no shifting or fluid motion. No fire, water, or wind observed.


A man wearing a dark hat, vest, light shirt, and dark pants sits near a wooden structure on the left in a dimly lit space. He lifts a bottle to his mouth, drinks, then lowers it to his lap. The camera remains shaky, focusing on his actions against a dark background.

A person (wearing a hat and vest) is holding and pouring liquid from a bottle; the motion includes pouring, adjusting the bottle, and manipulating it with hands.

The background is dark and static (a black box on the left remains fixed). There are no fluid/environmental motions (fire, water, wind) or significant ambient elements.


RAW CAPTION: Got it, let's tackle this. First, the video shows a person doing pull-ups. The main subject is a person, wearing a black tank top and black pants, with their back to the camera. They're on a pull-up bar, which is part of a metal gym apparatus. The sequence: they start with arms extended, then pull themselves up, then lower back down. The background has a white wall and some gym equipment, but minimal details. The camera is static, right? Looking at the video frames, the camera doesn't move; it's a fixed shot. So the description needs to be chronological: the person begins in a lowered position, pulls up, then lowers again. Check the rules: focus on motion, chronological, appearance (black outfit, back to camera), spatial relationships (in front of the pull-up bar, which is part of the gym equipment). Background minimal. Camera is static, top-down? Wait, the video shows a front view of the person from behind, so maybe the camera is at a slight angle but not top-down. Wait, the user says "top-down, pan left, slight shake" as examples. Here, it's a static shot, so "static camera" or "fixed angle". The rules say conclude with camera perspective and movement. So "static camera" or "fixed position".

Putting it all together: A person wearing a black tank top and black pants performs pull-ups on a metal pull-up bar. The individual starts with arms extended, pulls their body upward until the chin clears the bar, then lowers back down. The camera remains static, capturing the motion from behind the person. Background includes a white wall and gym equipment, but details are minimal. Wait, need to follow the rules: keep background minimal. So maybe mention "a gym setting with white walls and equipment visible" but not too much.

Let me structure: Chronological order. Start position: person gripping bar, legs bent (knees up), back to camera. Then pulling up (arms extend to pull body up), then lowering. Appearance: person in black top and pants, bald? The video shows a person with short hair, but maybe not necessary. Wait, the problem says "briefly describe their appearance and number (color, size, orientation)". So person, black outfit, back to camera. Spatial: in front of the pull-up bar, which is part of a metal apparatus. The pull-up bar is horizontal, person is hanging from it.

So the caption should be:

A person in black athletic wear performs pull-ups on a metal pull-up bar, facing away from the camera. The individual starts with arms extended, lifts their body upward until the upper body is elevated, then lowers back to the starting position. The camera remains static, capturing the motion from behind. The background includes a gym environment with white walls and minimal equipment visible.

Wait, need to check the rules. Rule d: conclude with camera perspective and movement. So "static camera" is correct. Also, check if spatial relationships are relevant. The person is on the bar, so "hanging from the bar".

Wait, the video: the person is on a pull-up bar, which is part of a power rack. So the bar is horizontal, the person is hanging by arms, knees bent (so legs are raised, not on the floor). Wait, in the frames, the person is gripping the bar with hands, legs bent, so they're in a pull-up position.

Let's get precise. The sequence:

- Frame 0: Person is gripping the bar, arms extended, body lowered (knees up, maybe squatting on the bar? Wait, pull-up bar usually has you hanging, but maybe it's a different setup. Wait, the video shows a pull-up bar, but the person is standing on the bar? No, the frames show the person with feet on the bar? Wait, no. Looking at the video: the person is doing pull-ups, so their feet are not on the bar. Wait, the first frame: person is holding the bar, arms straight, body pulled up? Wait, no. Wait, the video is a sequence of pull-up motion.

Wait, the first frame (0.0): person's arms are extended, body is pulled up (chin over bar), then at 0.1, they lower, 0.2 they pull up again. Wait, no, the frames: [0.0] shows person with arms up, body lowered, [0.1] same, then [0.2] starts moving up. Wait, the video is a loop? Wait, the user provided 5 frames (0.0 to 4.7), so:

- [0.0]: person gripping bar, arms extended, body in lowered position (knees bent, legs up)
- [0.1]: same position?
-

A person is performing pull-ups, moving their arms and body in a controlled, discrete manner due to physical exertion.

The background (gym walls, equipment) shows no uniform shifting or fluid motion; no fire, water, smoke, or wind is visible.


A person’s hand guides a silver electric iron with a red button across a white fabric laid on a surface. The iron glides back and forth over the fabric, pressing it flat. The camera captures close-up views of the iron and fabric, shifting slightly to follow the hand’s motion.

The iron and the hand holding it are moving back and forth over the clothing in a controlled motion.

No significant ambient environmental motion (fire, water, wind) observed. Background elements (floor, rack) are static without uniform shifting.


A man in a black shirt, black shorts, and black shoes uses a long pole to push a red bucket atop a gray box on grass in a backyard. He bends forward, manipulates the pole to shift the bucket, then stands upright. The background includes a house and white fence. The camera remains static throughout.

A person (solid object) interacts with a metal bucket and red lid, using a long tool to stir or manipulate contents. The person's body and tool movements are discrete and deliberate, involving locomotion and collision with the bucket/lid.

The background (white house, fence, trees, and chair) shows no shifting or fluid motion. No wind-induced tree swaying or environmental effects like water flow are visible. The scene is stable with no ambient fluid dynamics.


A person wearing white-framed sunglasses adjusts their head position slightly while seated indoors; they then raise their right hand to touch their cheek. The individual is positioned in front of a dimly lit room featuring a lamp to the right and a bright window with curtains to the left. The camera maintains a static, close-up perspective throughout.

A person wearing sunglasses moves their head and hand, exhibiting discrete, solid-object motion due to deliberate physical actions (e.g., turning head, touching face).

Background elements (window, walls) remain static with no shifting or fluid motion; no fire, water, smoke, or wind observed.


RAW CAPTION: Got it, let's tackle this. The video shows a man doing a stretch. First, he's on the floor in a lunge position, right? Then he stands up. Let's break it down chronologically.

The main subject is a man. His appearance: white t-shirt, black shorts, white cap, black shoes. He's in a living room with a beige couch, but background should be minimal. So first, he's in a lunge stretch, hands on the floor, then he pushes up to stand. Need to mention the motion: starts in a lunge, rises to a standing position. Spatially, he's in front of the couch, but maybe not necessary. Camera perspective: it's a static shot, right? The video frames don't show any camera movement. So camera is fixed, no movement.

Check the rules: focus on motion and behavior. So describe the action step by step. Also, keep background minimal. The couch is part of the background, but maybe just note that he's in a living room with a couch, but since the rules say minimal, maybe just the couch as a background element.

Let me structure it:

A man in a white t-shirt, black shorts, white cap, and black shoes is on the floor in a lunge position with one hand on the ground. He then pushes up to stand, transitioning from a prone position to an upright stance while maintaining a slight bend in his knees. The camera remains stationary, capturing the motion in a well-lit living room with a beige sectional sofa in the background.

Wait, check if the background is necessary. The problem says "exclude text recognition...". Also, "background descriptions minimal unless essential for understanding motion". So the couch is part of the setting, but maybe just mention it briefly.

Wait, the first frame: he's on the floor, legs in a lunge (one leg forward, one back), hands on the floor. Then he stands up. So the motion is from the lunge to standing.

So the caption should be:

A man wearing a white t-shirt, black shorts, white cap, and black shoes is in a lunge position on the floor with hands touching the ground; he then pushes up to a standing position, keeping one leg extended behind him. The camera remains stationary, capturing the motion in a living room with a beige sectional sofa visible in the background.

Wait, check if "one leg extended behind him" is accurate. In the frames, he starts with one knee down (lunge), then stands up, so the leg that was extended is still behind. Yes.

Also, need to mention the chronological order: starts in lunge, then stands.

Make sure it's concise. Let's see.

"A man in a white t-shirt, black shorts, white cap, and black shoes begins in a lunge position on the floor with hands on the ground, then rises to a standing position while maintaining a forward bend. The camera remains fixed, capturing the motion in a living room with a beige sectional sofa in the background."

Wait, "maintaining a forward bend"—maybe not. He's straightening up. Let's check the frames: frame 0, he's on the floor, hands on ground, body low. Frame 2, he's up, standing with legs apart. So the action is pushing up from the lunge to standing.

So revised: A man wearing a white t-shirt, black shorts, white cap, and black shoes starts in a prone lunge position on the floor with one hand on the ground, then stands up to an upright position while keeping one leg extended behind. The camera remains stationary throughout the sequence.

Is that concise? Let's check the rules. Background minimal—so mentioning "living room" might be okay, but the problem says "keep background descriptions minimal unless essential". The sofa is in the background, but maybe it's okay to note the setting as a living room with a sofa, but not too much.

Wait, the original instruction says "if relevant". Since the man is in front of the couch, maybe it's relevant. Let's see.

Another angle: the caption should not have too much background. So maybe "in a living room with a beige sofa" is minimal.

So putting it all together:

A man in a white t-shirt, black shorts, white cap, and black shoes is on the floor in a lunge position with hands on the ground; he then stands up to an upright stance while keeping one leg extended behind. The camera remains stationary, capturing the motion in a living room with a beige sectional sofa in the background.

Wait, "one hand on the ground" in frame 0. Then in frame 2, he has both hands on hips? Wait no, let's check the frames again.

Frame 0: He's on the floor, hands on ground (maybe both hands?

A person (man) is performing a stretching exercise, moving from a lunge position to a more upright stance.

Background elements (couch, wall, art piece) are stationary; no fire, water, smoke, or wind observed.
