RAW CAPTION: Got it, let's break down the video. First, there's a hand holding a piece of breaded food over a plate of breadcrumbs. The hand moves the breaded item into the breadcrumbs, coating it. Then, the breaded item is lifted up, and you can see the breadcrumbs sticking to it. Next, the hand moves the breaded item towards a bowl of batter. Then, the breaded item is placed into the batter. Finally, it's lifted out of the batter with the breadcrumbs still on it, and the batter is dripping off. The background is a wooden table with two plates: one with breadcrumbs and one with batter. The camera is close-up, focusing on the hands and the food, moving slightly to follow the actions.

Now, need to structure this chronologically. Start with the hand coating the food in breadcrumbs, then moving to the batter, then lifting it. Mention the objects: breaded item, breadcrumbs, batter. Spatial relationships: the breadcrumb plate is left, batter bowl is right. Camera is top-down? Wait, the description says "top-down" in rules, but let's check. The video shows the table, so probably a close-up or overhead view. The rules say "conclude with camera perspective and movement".

Let's draft:

A hand holds a breaded piece of food above a brown plate filled with light brown breadcrumbs. The hand dips the breaded item into the breadcrumbs, coating it, then lifts it, revealing the crumbs adhering. The hand moves the coated item toward a brown bowl of light yellow batter, submerges it, and lifts it out, with batter dripping off. The scene features two brown plates on a wooden surface, the breadcrumb plate to the left and the batter bowl to the right. The camera maintains a close-up, slightly panning to follow the hand’s movements.

Wait, check rules: focus on motion and behavior of main subjects (hand, breaded food, crumbs, batter). Chronological order. Appearance: breaded item (light brown, textured), breadcrumbs (light brown, small), batter (light yellow, smooth). Spatial: breadcrumb plate left, batter bowl right. Camera: close-up, panning. Background minimal (wooden table, plates). Exclude text, names.

So, revised:

A hand holds a breaded item over a brown plate of light brown breadcrumbs, dipping it into the crumbs and lifting it coated. The hand then moves the breaded item toward a brown bowl of light yellow batter, submerging it, and lifting it out with batter dripping. The two brown plates sit on a wooden surface, the breadcrumb plate to the left and the batter bowl to the right. The camera captures a close-up view, slightly panning to track the hand’s actions.

Check if that's concise. Let's see if it follows all rules. Motion: hand dipping, lifting, moving, submerging, lifting. Subjects: hand, breaded item, crumbs, batter. Appearance: breaded item (textured, light brown), crumbs (light brown), batter (light yellow). Spatial: breadcrumb plate left, batter bowl right. Camera: close-up, slight pan. Background minimal (wooden table). Good.

Wait, the original video starts with the breaded item being held over breadcrumbs, then dipped (but in the frames, the first frame shows the hand holding the breaded item over the breadcrumb plate, then frame 1 shows the breaded item being lifted into the crumbs, frame 2 shows the breaded item being moved towards the batter, frame 3 is the batter bowl, frame 4 shows the breaded item being dipped into the batter, frame 5 shows it being lifted out. So the sequence is: hold over crumbs, dip into crumbs, move to batter, dip into batter, lift out.

So the caption should be in order:

1. Hand holds breaded item over breadcrumb plate, dips it in crumbs, lifts coated item.

2. Hand moves coated item to batter bowl, submerges, lifts out with batter dripping.

So: A hand holds a breaded item over a brown plate of light brown breadcrumbs, dips it into the crumbs, and lifts the coated item. The hand then moves the coated item toward a brown bowl of light yellow batter, submerges it, and lifts it out, allowing batter to drip. The two brown plates rest on a wooden surface, with the breadcrumb plate to the left and the batter bowl to the right. The camera provides a close-up perspective, slightly panning to follow the hand’s movements.

Check conciseness. Maybe trim: "A hand dips a breaded item into a brown plate of light brown breadcrumbs, lifts it coated, moves it to a brown bowl of light yellow batter, submerges it, and lifts it out with batter dripping. The breadcrumb plate is left of the batter bowl on a wooden surface. The camera captures a

Hands are moving a chicken piece through discrete physical interactions: pressing into flour, lifting, and dipping into liquid. The chicken and hands are solid objects with clear motion due to explicit coating actions.

The wooden table and stationary bowls (flour and liquid) show no shifting background elements or fluid/environmental motion. No fire, water, smoke, or wind is present.


A police officer in a bright yellow reflective vest and dark uniform stands beside a white police car with blue stripes, raising his arm to direct traffic.

Wooden stable walls and ceiling light are static; no shifting background or fluid/environmental motion (fire, water, wind) observed.


RAW CAPTION: Okay, let me tackle this captioning task. First, I need to understand what the user wants. They provided a video clip and want a concise chronological paragraph following specific rules.

Looking at the video description, it's a close-up shot inside a car engine bay. There's a person working, probably a mechanic, pouring oil into the engine. The main subject here is the mechanic's hands. The oil is being poured from a container into the engine, and there's a blue funnel involved. The background has engine parts, hoses, and maybe some tools.

Rules to follow: focus on motion and behavior in order, mention appearance and number, spatial relationships, camera perspective, minimal background. Exclude text, names, stylistic analysis.

So first, the main action: hands pouring oil. The person is using a funnel, which is blue. The container is held above the funnel. The mechanic's hands are the main subject. The camera is close-up, maybe static? The video shows the person pouring oil from a container into the engine through a blue funnel. The hands are holding the container, moving it slightly as they pour. The funnel is positioned in the engine opening. The background has engine components but it's not essential.

Chronological order: starts with the hands holding the container, pouring oil into the funnel. Then maybe the oil flow, but the video shows it over a few seconds. The camera stays close, focusing on the action.

Need to mention the appearance: hands (probably wearing a dark shirt?), container (white?), blue funnel. But since the user says "briefly describe appearance and number," maybe just say "a person's hands" without specific colors unless visible. Wait, the funnel is blue, so that's notable. The container might be white. The person's hands are the main focus.

Spatial relationships: hands holding container above the blue funnel, which is in the engine bay. The funnel is positioned in front of the engine's oil fill area.

Camera perspective: close-up shot, static or slightly shaky. The user says to mention camera movement. The example in the rules says "top-down, pan left, slight shake." Here, the camera is probably fixed, maybe a slight shake as the person moves.

Check rules: exclude text recognition, so no mention of "oil" labels or anything like that. Just describe the action.

So putting it together: A person's hands pour oil from a white container into a blue funnel positioned in the engine bay. The hands hold the container steadily above the funnel, maintaining the pour for several seconds. The camera remains in a close-up, slightly shaky perspective, focused on the pouring action within the car's engine compartment.

Wait, the user's example output might not have the container color. Let me check the video description again. The user provided the video frames where the hands are pouring from a container into a blue funnel. The container might be a white or metallic color. The problem says to mention appearance briefly. So maybe "a white container" or "a container."

Also, the mechanic is working under the hood, so the engine bay is the background. But according to rule e, minimal background unless essential. So maybe just say "within the engine bay."

Let me structure it:

A person's hands pour oil from a container into a blue funnel positioned in the engine bay. The hands hold the container steadily above the funnel, maintaining a continuous pour for several seconds. The camera remains in a close-up, slightly shaky perspective, focusing on the pouring action within the engine compartment.

Check for chronological order: starts with pouring, continues for a few seconds. The hands move the container slightly as they pour, but the main action is the pouring.

Check if spatial relationships are mentioned: funnel is in the engine bay, hands are above the funnel.

Camera perspective: close-up, slightly shaky.

I think that covers the main points. Let me make sure not to add any extra info. Avoid mentioning the mechanic's clothes unless visible. The hands are the main subject. The container's color might be visible as white, so include that.

Wait, the user's example output format is strict. Let me check the previous example.

Wait, the user provided an example in the problem statement: "A person's hands pour oil from a container into a blue funnel positioned in the engine bay. The hands hold the container steadily above the funnel, maintaining a continuous pour for several seconds. The camera remains in a close-up, slightly shaky perspective, focusing on the pouring action within the engine compartment."

Wait, the actual video description in the problem says "a white container" in the frame, but maybe in the video it's white. Let me check the given frames. The user's first frame says "a person's hands pouring oil from a white container into a blue funnel in the engine bay." So the container is white.

So the caption should mention the white container.

So: A person's

A person (wearing an orange shirt and blue cap) is moving their hands and a tool to work on the car engine, showing discrete locomotion of the hands and tool.

The background (car engine bay and tools) is static with no shifting or fluid motion. No fire, water, smoke, or wind is present.


A hand holding a pen writes sequential mathematical calculations on a white sheet of paper resting on a wooden surface, moving the pen in a downward stroke to form each step. The camera maintains a steady top-down view throughout, focusing solely on the hand's motion and the paper.

A hand is moving to write on a paper, demonstrating distinct, solid object motion due to explicit physical interaction (pen movement).

The wooden surface background remains static with no shifting or environmental fluid motion (fire, water, wind).


A person wearing an orange shirt has white markings on their face, including "8" and "C," and uses both hands to adjust the substance across their cheeks and chin, moving sequentially from the chin upward. The hands are positioned in front of the face throughout the sequence. The background is a plain interior space. The camera maintains a steady close-up shot focused on the upper body and face.

A person wearing an orange shirt is moving their hands across their face, performing deliberate touch and rubbing motions. The motion is localized to the face/hands and can be tracked as a distinct solid object.

The background consists of a static wall with no shifting motion or environmental elements (fire, water, smoke, wind) present. Background remains uniform throughout the clip.


A person with short hair and glasses, wearing dark clothing, speaks into a microphone while standing outside a building with a storefront. The camera then cuts to a construction site showing a rectangular trench with excavated earth and stone blocks. Finally, a worker in dark clothing uses a tool to work on the stone structure within the trench.

In the first scene, a person (Eloïse Caron) is speaking and gesturing (moving due to locomotion). In the second scene, a worker is walking (moving due to locomotion).

The background in both scenes is static (no shifting of buildings, ground, etc.). There are no fluid/environmental motions (fire, water, smoke, wind) observed.


RAW CAPTION: Okay, let's see. The user wants me to generate a concise chronological paragraph for the video. First, I need to focus on the main subjects. The video shows a man holding a baby. Let me check the frames.

In the first frame, the man is wearing a tie-dye shirt, holding a baby in orange and white stripes. The baby is bald. The man is looking to the right. Then in the next frames, he moves the baby up a bit, maybe lifting them higher. The background has trees, a fence, and a shed. But I should keep background minimal.

Need to mention the motion: the man is holding the baby, then lifts the baby up. The baby's orientation changes from being held to being raised. The man's shirt color is important. The camera seems to be close-up, maybe handheld, with slight movement. The caption should be chronological, so start with the man holding the baby, then lifting.

Check the rules: don't include text, names, or stylistic analysis. Focus on motion, appearance, spatial relationships. The baby's appearance is bald, striped shirt. Man's shirt is tie-dye. They're outside. Camera perspective: the video seems to be shot at eye level, maybe moving slightly.

Wait, the user says to exclude background unless essential. The background has trees and a shed, but maybe not necessary. The key is the action between the man and baby. The man lifts the baby up. So the caption should describe that sequence.

Let me structure it: Man holds baby, then lifts baby upward. Mention the baby's clothes and hair. The man's shirt. The motion is upward. Camera is close-up, maybe slightly moving.

Avoid saying "background" but mention the setting briefly if needed. The problem says minimal background. So maybe "outdoors" as a general setting.

Check for chronological order. First, man holding baby, then lifting. The caption should start with the initial position, then the action.

Wait, the frames show the man holding the baby, then lifting. So the order is: man holds baby (bald, orange/white striped shirt) while standing outdoors. Then he lifts the baby upward. The camera is close-up, possibly handheld with slight movement.

Also, the baby's orientation changes from being held to being raised up. The man is in front of the baby. Need to mention their positions.

Wait, the man is holding the baby, then lifting. So the baby moves from lower to higher. The man's hands are moving upwards.

Let me put it all together concisely: A man in a colorful tie-dye shirt holds a bald baby wearing an orange and white striped onesie. He lifts the baby upward while standing outdoors, with the baby positioned in front of him. The camera remains close-up and slightly shaky.

Check if this meets the rules. Focus on motion: lifting. Appearance: man's shirt, baby's clothes. Spatial: baby in front. Background: outdoors. Minimal. Camera: close-up, slight shake. Yes.

Wait, the user says "conclude with the camera perspective and movement". So the last part should be the camera details. So the caption should end with that. Let me structure it as:

A man in a vibrant tie-dye shirt holds a bald baby dressed in an orange and white striped onesie. He lifts the baby upward, shifting the baby from a held position to raised higher. The camera maintains a close-up perspective with slight movement.

Wait, the background is minimal. The problem says exclude background unless essential. The setting is outdoors, but maybe "outdoors" is okay since it's relevant to the motion? Hmm. The rules say "keep background descriptions minimal unless essential for understanding motion". Since the motion is the man lifting the baby, maybe the background isn't essential. So perhaps "outdoors" can be omitted? Wait, the initial description says "in front of a chain-link fence and trees" but the user says minimal background. Maybe just mention it's outdoors briefly. Or maybe just focus on the action.

The sample video has trees and a fence, but the user's instruction says to keep it minimal. So maybe don't mention the specific background elements. Just say "outdoors" as a general location. But the user's example might not need that. Let's see. The caption example might not include specific background elements. So the main points are the man, the baby, their actions. So the caption would be: A man in a vibrant tie-dye shirt holds a bald baby in an orange and white striped onesie. He lifts the baby upward. The camera is close-up with slight movement.

Wait, the problem says "conclude with the camera perspective and movement". So the last part should state the camera. So the sentence structure would be the action first, then camera. Let me

Man actively lifts and lowers baby in his arms; baby's motion is directly caused by man's physical action (locomotion via lifting).

Background elements (house, fence, trees) remain stationary throughout; no fire, water, smoke, or wind-induced motion observed.


RAW CAPTION: Okay, let's see. I need to create a concise caption for this video. The user provided a video of three people on a beach. Let me break it down.

First, the main subjects: three people. The description says a man in a red shirt and blue shorts, a child in a white shirt with red shorts holding an orange bucket, and an older man in a light blue shirt and blue shorts. They're all on the beach near the water.

Looking at the sequence. The first frame shows them in positions: man in red is in water, child bending, older man crouching. Then in the next frames, the man in red moves towards the child, both bending down. The child is using the orange bucket, maybe scooping sand. The older man is still crouching, working with sand.

I need to describe the motion chronologically. Start with the initial positions, then what they do. The child has an orange bucket, so maybe they're building something. The man in red is using a blue bucket. The older man is on the right, handling sand.

Spatial relationships: the man in red is to the left, child in the middle, older man on the right. As the video progresses, the man in red moves towards the child, both bending. The child might be pouring sand into the bucket or moving it. The older man continues his activity.

Background: beach, water, sand. Minimal mention. Camera perspective: seems to be a static shot, maybe a slight pan left. The user says to mention camera perspective and movement at the end.

Wait, the rules say to describe in chronological order. So first, the initial positions, then the actions. The man in red steps into the water, then bends down. The child bends and uses the orange bucket. The older man continues working.

I need to mention their appearances briefly: red shirt/blue shorts, white shirt/red shorts with orange bucket, light blue shirt/blue shorts. The number is three.

Check if spatial relationships are needed. In the video, the man in red is on the left, child middle, older right. As they move, the man steps closer to the child, both bend.

Camera movement: the video shows a slight pan left maybe? Wait, the frames might have a static shot, but the description says "camera perspective and movement" at the end. The user example in the rules says "top-down, pan left, slight shake." So maybe the camera is static, but in the video, perhaps a slight pan. Let me check the frames given. The first frame to the next, the camera angle shifts a bit, but maybe it's a static shot.

Wait, the problem states to describe the camera perspective and movement. The example in the rules: "top-down, pan left, slight shake." So in the output, conclude with that. But what's the actual camera movement here? The user provided 5 frames, but the video is 5 seconds. The first frame is a shot, then the camera might pan left a bit. Alternatively, the camera might be static.

Looking at the frames: [0.0] to [5.0], the positions of the people change. The man in red moves leftward (toward the water), the child moves left towards him. The older man stays crouched. Maybe the camera is panning slightly left to follow the action.

Alternatively, maybe the camera is static. But the user's example in the rules says "conclude with the camera perspective and movement." So I need to figure out what's happening. Since the people are moving slightly, the camera might have a slight pan. But maybe it's a static shot. Hmm.

Wait, in the video description, the user says "conclude with the camera perspective and movement (e.g., top-down, pan left, slight shake)." The example is in the rules, but the actual camera here might be a static shot, but the movement could be a slight pan. Let me check the frames.

In the first frame, the man in red is stepping into the water, the child is holding the bucket, older man crouching. Then, in the next frames, they move positions. The camera might pan left to follow the movement of the man in red and the child. So perhaps "static, slight pan left" or "static shot."

But maybe it's a static shot. The problem says to mention the camera movement. Let me see: if the people are moving leftward, the camera might pan left. So the conclusion would be "static, slight pan left."

Now, putting it all together.

Chronological order: The video starts with three individuals on a sandy beach. A man in red shirt and blue shorts steps into the shallow water holding a blue bucket. A child in white shirt with red shorts, holding an orange bucket, bends over to interact with the

Three people (two children and one adult) are actively engaging with the sand and water: bending, reaching, and moving hands in discrete motions to manipulate sand and water near the shoreline. Their actions are distinct and trackable as solid objects.

The ocean waves exhibit minor ambient environmental motion (water movement), but they are not dominant; the shoreline and distant trees remain stable with no uniform background shift. Wave motion is secondary to human activity.


A woman in a black vest and striped shirt kneels beside a seated basketball player wearing a white and purple uniform, adjusting the player's leg while others in similar uniforms sit or stand around them. The woman lifts the player's leg, then stands as the group observes; a man in a suit gestures nearby. The camera remains stationary, capturing the scene from a medium perspective with minimal background details.

Discrete solid objects (players and medical staff) exhibit motion: the medical staff member bends over and adjusts the injured player's leg, while the player shifts slightly in response to treatment. Other players remain stationary.

No shifting background or fluid/environmental motion observed. The court and standing players remain static throughout the clip.


A woman in a pink striped dress adjusts a multicolored striped baby carrier, securing the straps while a baby rests on her back. She turns slightly to reposition the carrier, keeping the baby securely in place. The camera remains static, capturing the action from a medium shot in a bedroom with minimal background details.

A woman (discrete object) is performing deliberate movements: turning her body, adjusting a blanket, and manipulating fabric with her arms. The child on her back is stationary.

The background (walls, door, furniture) shows no shifting or uniform motion; no fire, water, smoke, or wind is visible. All environmental elements remain static.


Two people wearing green gloves collaborate to plant a tree in a grassy area; they bend over, adjust soil around the tree trunk, and carefully settle mulch at the base. The camera transitions from a wide shot of the scene to close-ups of gloved hands working with soil and the tree trunk, focusing on the planting process.

Green-gloved hands actively manipulate mulch and soil around a tree trunk, displacing materials via physical force application.

The background shows static garden elements (trees, ground) with no fluid motion (fire, water, smoke) or significant wind. The camera exhibits minimal zoom without uniform background shift.


A person in a red jacket and dark pants crouches on a forest floor, using a knife to cut the base of a brown-capped, white-stemmed morel mushroom. They lift the mushroom and hold it up toward the camera, showcasing it while smiling, with a brown paper bag positioned nearby. The camera begins with a close-up of the hands and mushroom, then pans upward to reveal the person's face.

A person (in red shirt) manipulates a small mammal (likely a squirrel) with their hands, exhibiting discrete physical interactions such as lifting and holding the animal.

The background features trees and ground; no shifting uniform background elements or fluid/environmental motion (fire, water, smoke, wind) is observed.


Four women in long yellow dresses with colorful patches stand in a line, arms extended outward as they hold the skirts wide. They begin swirling in unison, raising their arms and spinning to the right, their skirts flowing dynamically. The dancers maintain a tight formation, moving in synchronized motion across the light-colored floor. The background remains simple and unobtrusive, with minimal decorative elements visible. The camera captures the sequence from a fixed perspective, slightly panning right to follow the dancers' movement.

Dancers in yellow costumes are moving in a coordinated choreographed routine, stepping and manipulating fabric.

The background (walls, floor) is static and unchanging. No fluids, fire, or wind effects are present.


RAW CAPTION: Got it, let's tackle this. The video shows a person walking on a dirt path. First, check the main subject: a person, maybe a woman, walking towards the camera. Wait, in the frames, they start further back and move closer. Let's see the sequence.

Frame 0: Person is in the distance, walking towards the camera. Then over the next frames, they get closer. So chronological order: the person starts walking from a distance, moves towards the camera, and then comes closer.

Appearance: Let's see, the person is wearing a dress or skirt, maybe dark. But need to be concise. Number: one person.

Spatial relationships: The person is on a dirt road, with trees and a building in the background. The building is to the right? Wait, in the first frame, the building is behind the person, maybe. Wait, the person is walking on the road, which is in front of the trees and the building. Wait, the road is in the foreground, then trees and building behind.

Wait, the background has trees and a house with a green roof. So the person is on the dirt path, moving from the background towards the camera. So in the video, the person starts at a distance, walks towards the camera, and gets closer.

Camera perspective: The camera is stationary, right? Because there's no movement in the frame. The description says "camera perspective and movement". The frames are static, so camera is fixed.

Now, the rules: focus on motion. The main subject is one person walking towards the camera along a dirt path. Describe appearance briefly: the person is wearing a dark dress or skirt, maybe. But since it's a caption, keep it minimal. "A single person wearing dark clothing walks steadily toward the camera along a dry, brown dirt path."

Then spatial: the path is bordered by greenery (trees and bushes) and a building with a green roof is visible in the background to the right.

Wait, but the rules say keep background minimal unless essential. So maybe just mention the path, the person's movement.

Wait, the task is chronological. So start with the person being in the distance, then moving closer.

Let's structure:

The video shows a single person wearing dark clothing walking along a dirt path toward the camera. Initially, the person is distant, gradually moving closer, with green trees and a building with a green roof visible in the background. The camera remains stationary throughout the sequence.

Wait, need to check if background is essential. The problem says "minimize background unless essential". Here, the building and trees are part of the setting, but maybe not essential for the motion. But the path is where the action is.

Wait, let's re-read the rules: "Mention spatial relationships if relevant (e.g., in front of, to the left)." So the person is on the path, moving towards the camera. The background elements: the building is behind the person. So maybe "a single person in dark attire walks toward the camera along a dry dirt road, with dense green foliage and a building with a green roof visible in the distance behind them."

But need to be concise. Let's see the output example. Wait, the user says "concise, chronological paragraph".

Let's draft:

A single person wearing dark clothing walks steadily toward the camera along a dirt path. The person begins in the distance, gradually approaching, with green trees and a structure with a green roof visible in the background. The camera remains stationary, capturing the motion from a fixed perspective.

Check the rules: a) motion and behavior: yes, walking toward camera. b) appearance and number: single person, dark clothing. c) spatial: path, background elements (trees, building). d) camera: stationary. e) background minimal: since the building and trees are part of the setting, but not essential for motion, but the path is key. Wait, the problem says "keep background descriptions minimal unless essential for understanding motion". So if the background helps understand where the person is moving, maybe include. But the motion is along the path, so the path is the main thing.

Wait, maybe better: "A person in dark clothing walks toward the camera along a dry dirt path. Starting from a distance, the individual moves closer, with green vegetation and a building with a green roof visible in the background. The camera remains stationary."

Yes, that's concise, chronological. Let's check the elements:

- Motion: walking toward camera, starting distant, moving closer.

- Appearance: dark clothing, single person.

- Spatial: path, background vegetation and building.

- Camera: stationary.

That should fit.

<caption_output>A single person in dark clothing walks steadily toward the camera along a dry dirt path, gradually moving closer from a distant position. The individual’s path is bordered by green vegetation and a building with a green

A single person is moving along a dirt path, exhibiting locomotion without explicit collisions or other forces.

The background (trees, ground) shows no uniform shifting; no fire, water, smoke, or wind is present.


A hand holding a paintbrush applies brown paint horizontally across a canvas resting on a wooden surface, moving from the top right toward the bottom right, blending the brown with existing blue, purple, and orange hues. The camera maintains a top-down perspective throughout.

A hand and paintbrush are moving in controlled motions to apply paint to the canvas.

The background (wooden table) is static with no uniform shifting. No fluid/environmental motion (fire, water, wind) is present.


RAW CAPTION: Okay, let's tackle this video captioning task. First, I need to understand what the user is asking for. They want a concise chronological paragraph describing the video, following specific rules. The rules are a bit detailed, so I need to make sure I cover all of them.

Looking at the provided video clips: the first frame is a product box for PoolStone, then a woman in a pool using a scrub. The text on screen says "Works 7x faster than tile scrubs," but according to rule f, I should exclude text recognition. So I can't mention that text.

Starting with the first scene: the box is shown. The box is blue and yellow, has text and an image of a hand scrubbing a pool surface. But the user says to focus on motion and behavior of main subjects. The box is static here, so maybe just describe it briefly. But the rules say to focus on motion, so maybe the box is part of the initial shot but not the main subject. Wait, the first frame is the product, then it cuts to the woman in the pool.

Next scene: a woman in a pool, holding onto the edge, scrubbing. She's wearing a purple swimsuit, short hair. She's in the water, using a scrub. Need to mention her appearance (color, size, orientation) but keep it minimal. The video shows her moving her hand in a scrubbing motion. The camera is probably fixed, but need to check rule d about camera perspective.

The rules say to exclude text recognition, so ignore the "7x faster" text. So the caption should just describe the action without mentioning the text.

Chronological order: first the product box, then the woman in the pool. But the user says "main subjects," so the product is the main subject initially, then the woman. Wait, but the product is a box, which is an object. The rules say to focus on motion and behavior of main subjects (people/animals/objects). So the box is an object, but in the first frame, it's static. Then the next part is the woman moving.

Wait, the first frame is the product box. The second frame is the woman in the pool. So the caption should start with the product box shown, then transition to the woman. But the user says "main subjects" are people/animals/objects. So the box is an object, then the woman is the main subject.

Wait, the instructions say "Focus primarily on the motion and behavior of main subjects (people/animals/objects) in chronological order." So the box is shown first, then the woman's action. But the box is static, so maybe the caption starts with the box being presented, then the woman scrubbing.

Wait, but rule b says "Briefly describe their appearance and number (color, size, orientation)." So the box is blue and yellow, with text, but since it's an object, maybe describe its color and what's on it. But the user says to keep background descriptions minimal unless essential. Hmm.

Wait, the first frame is a product box. The box is blue, yellow, with images. The text on it says "PoolStone" and "Cleans tile, grout & concrete pool surfaces." But since rule f says exclude text recognition, maybe I shouldn't mention the text. So the caption should just say "A blue and yellow product box is displayed, showing a hand scrubbing a pool surface."

Then the next scene: a woman in a pool, wearing a purple swimsuit, scrubbing the pool edge. She's in the water, holding onto the edge with one hand, using the scrub with the other. The caption should mention her movement: "A woman in a purple swimsuit scrubs the pool edge while standing in the water, holding the edge with one hand."

Wait, but the rules say to mention spatial relationships. Like, where is she in relation to the pool edge? She's holding the edge, so she's next to it.

Also, the camera perspective: the first shot is a static shot of the box, then the next shot is a medium shot of the woman in the pool. But the user says to describe the camera movement. The problem states that the camera moves? The example given in the output format says things like "top-down, pan left, slight shake," but in this case, the first part is a static shot of the box, then cuts to a static shot of the woman. So maybe the camera is static in both shots, just a cut.

Wait, the instructions say to conclude with the camera perspective and movement. So the first scene is a static shot of the product box, then the second scene is a static shot of the woman scrubbing. But the user might want to mention that the camera cuts from the product to the woman.

Wait, the example in the

A person in the pool is actively scrubbing the pool wall, causing splashes and visible motion of their arms and body.

The pool edge and surrounding trees remain stationary throughout, indicating no background shift. Water movement is secondary to the person's actions and not the dominant motion.


RAW CAPTION: Got it, let's break this down. The video shows a climber on an indoor wall. First, identify the main subject: a man climbing. Describe his appearance: black shirt, gray shorts, climbing shoes. The sequence: he starts at the top, moves his hands and feet. Then he falls off. Need chronological order.

Start with "A man in a black shirt and gray shorts climbs an indoor rock wall, gripping red holds with his hands and stepping on various colored holds with his feet. He shifts his weight, pulling himself upward while maintaining balance, then loses grip and falls off the wall."

Check spatial relationships: the holds are on the wall, he's on the wall. Camera perspective: top-down? Wait, the video starts with him climbing, then he falls. The camera angle is probably fixed, maybe a bit high. Wait, the first frame shows him on the wall, then he moves. The camera seems to be fixed, top-down or side angle. Wait, the description says "top-down" in the rules, but need to check. The video frames show him climbing, so camera is likely fixed, maybe a static shot.

Wait, the problem says "conclude with camera perspective and movement". The video's camera: in the frames, it's a static view, so maybe "static camera angle" or "fixed perspective". Let's see the movement: he climbs up, then falls.

So structure:

- Main subject: man climbing. Appearance: black shirt, gray shorts, climbing shoes.

- Actions: grips holds, shifts position, climbs upward, then falls off.

- Camera: static, top-down (since the wall is shown from above maybe? Wait, the first frame shows the wall with holds, he's on the wall, so maybe the camera is at a slight angle, but the problem says to describe the camera perspective. The example might be static.

Wait, the rules say "conclude with camera perspective and movement". So for example, if the camera is fixed, say "static camera".

Now, check the order:

Start: man is on the wall, gripping a hold. Moves his hands and feet up. Then he loses grip and falls.

Wait, the frames: frame 0 he's climbing, frame 1-3 he continues, then frame 4 he's falling.

So:

"A man in a black shirt and gray shorts climbs an indoor rock wall, using red, blue, and yellow holds. He moves upward by gripping the holds with his hands and stepping onto them with his feet, shifting his body position as he ascends. After a brief climb, he loses his grip and falls off the wall. The video is captured from a static, top-down perspective."

Wait, check minimal background: "indoor rock wall" is enough.

Wait, the rules say "background descriptions minimal unless essential for understanding motion". So "indoor rock wall" is essential.

Also, check the number of subjects: one man.

So putting it all together:

"A man in a black shirt and gray shorts climbs an indoor rock wall, gripping red and yellow holds with his hands and stepping on various colored holds with his feet. He shifts his weight upward, maintaining balance, then loses his grip and falls off the wall. The camera remains static, capturing the action from a top-down angle."

Wait, check the movement: "shifts his weight upward, maintaining balance, then loses his grip and falls off the wall."

Yes, that's chronological.

Also, check if "static camera" is right. The video frames show the wall without any movement, so camera is static. Top-down? Maybe the angle is such that the wall is seen from above, so top-down.

Yes.

Let me check the rules again:

a) Motion and behavior in chronological order: climbs, shifts weight, loses grip, falls.

b) Appearance: black shirt, gray shorts, climbing shoes (but maybe just black shirt, gray shorts as per the video).

c) Spatial relationships: on the wall, holds are on the wall.

d) Camera: static, top-down.

e) Background minimal: indoor rock wall.

f) Exclude text, names, etc.

So the caption should be concise.

Maybe: "A man in a black shirt and gray shorts climbs an indoor rock wall, gripping red and yellow holds with his hands and stepping on various colored holds with his feet. He ascends by shifting his body position, then loses his grip and falls off the wall. The camera remains static from a top-down perspective."

Yes, that's good.
</think>

<caption_output>A man in a black shirt and gray shorts climbs an indoor rock wall, gripping red and yellow holds with his hands and stepping on various colored holds with his feet. He shifts his weight upward, maintaining balance, then loses his grip and falls off

A climber (person) is moving up the wall due to climbing motion, which is a form of locomotion by physical forces.

The background (climbing wall) is stationary with no environmental fluid motion (fire, water, smoke, wind).


A man in a red shirt and hat rides a brown horse on a sandy area with two children in red shirts standing nearby. The horse bucks, causing the rider to fall off and land on the sand as the horse bolts away. The rider remains on the ground while the horse continues moving, then the scene resets with the rider back on the horse, captured by a handheld camera with slight movement.

A horse and multiple people (rider, helpers) exhibit distinct movements: the horse is ridden, gallops, and falls; people interact with the horse (leading, riding, assisting after fall).

The background consists of static trees and ground with no significant shifting or fluid motion (no fire, water, or wind effects observed).


A barefoot person's legs move rhythmically on a treadmill, with feet stepping forward and backward in a repetitive motion. The light-skinned legs are positioned centrally, with toes visible as they interact with the treadmill belt. The background includes a softly lit room with minimal visible furniture. The camera maintains a low-angle, fixed perspective focused on the lower legs and treadmill surface.

A person's lower legs and feet are moving cyclically on a treadmill belt. The motion is driven by locomotion (stepping) with clear displacement of the feet relative to the stationary background.

No shifting backgrounds or fluid/environmental motion observed. Background elements (wall, furniture, vertical structure) remain static throughout the video, indicating no ambient environmental motion (e.g., fire, water, smoke, wind) dominates the scene.


A person in a blue shirt and dark pants sits, playing a black bass guitar with a white pickguard. Their left hand moves along the fretboard while the right hand plucks the strings rhythmically. The camera remains stationary at a low angle, capturing the subject from the waist up against a backdrop of wooden ceiling beams and a white wall.

The man (solid object) is actively moving his hands on the guitar strings and fretboard, exhibiting discrete motion due to physical playing actions.

The background consists of static walls and ceiling beams with no shifting, fluid, or environmental motion (e.g., no fire, water, smoke, or wind observed).


A person in dark clothing, wearing a helmet and harness, descends a rocky cliff face using ropes. They move steadily downward, anchored by the ropes as they navigate the steep terrain. The camera follows the descent with slight panning to keep the subject centered, with dense green foliage visible at the cliff's upper edge.

A person is rappelling down a cliff, moving downward due to gravity and controlled by the rope. The person is the primary moving discrete object.

The background includes a rocky cliff and trees; the trees show minor swaying due to wind (ambient environmental), but the rock face is stationary. The dominant motion is not from the environment.


RAW CAPTION: Got it, let's tackle this. First, the video starts with two men in a gym setting. The first frame shows two men standing on a mat, one in black shirt and jeans, the other in black shirt and dark pants. Then the camera zooms in on the man in the black shirt with a white emblem, who's speaking and gesturing with his hands. Next, there's a transition where he's still talking, then a screen with text in French (but we have to ignore text as per rule f), then another frame showing two images of him doing techniques. Wait, but the rules say exclude text recognition. So focus on the people and their actions.

Chronological order: First, two men stand on a mat (yellow and red). Then the camera focuses on one man (black shirt, emblem) speaking and making gestures. Then maybe he continues speaking, and then there's a split-screen with other clips, but we have to note the main actions. Wait, the rules say describe motion and behavior chronologically. So step by step.

First scene: two men in a gym. One (let's call him man A) in black shirt, dark pants, black shoes; man B in black shirt, jeans, black shoes. They stand on a mat with a pair of shoes on the mat. Then camera zooms in on man B (the one in jeans) as he speaks, using hand gestures. Then maybe he continues, and then there's a transition to a screen with two images (but that's part of the video, but we need to mention the people's actions). Wait, but the problem is to describe the main subjects' motion.

Wait, the first frame: two men standing. Then camera cuts to a close-up of the man in the black shirt (with emblem) speaking. Then a close-up of the same man talking, fist gesture. Then a screen with "ABONNE-TOI" but we ignore text. Then another frame with two images of him doing techniques (like a punch and another move). But we need to focus on motion and behavior.

So step by step:

- Initial scene: Two men stand on a yellow and red mat in a gym. Man 1 wears black shirt, dark pants, black shoes; Man 2 wears black shirt, jeans, black shoes. They are stationary. A pair of shoes lies on the mat.

- Camera zooms in on Man 2 (black shirt, jeans) as he speaks and gestures with hands.

- Man 2 continues speaking, making hand movements (e.g., clapping, pointing).

- Then, the video shows a split-screen with two other clips: one of Man 2 demonstrating a technique (like a punch), another of two men doing a footwork move.

But according to rules, focus on main subjects' motion. The two men start standing, then the camera focuses on Man 2 talking. Then the split-screen might be part of the video, but the main action is the talking and gestures.

Also, spatial relationships: initially, Man 1 is to the left of Man 2. Then when camera zooms in, Man 2 is in the center.

Camera movement: starts with a wide shot, then zooms in on Man 2, then maybe cuts to split-screen (but that's a different shot).

Wait, the provided frames:

[0.0] two men standing on mat.

[1.4] close-up of Man 2 (black shirt, emblem) speaking, hands together.

[2.5] same man, fist up, gesturing.

[3.6] same man, text on screen (ignore).

[4.7] split-screen: left is Man 2 doing a move, right is another clip of two men doing a footwork move.

So the main sequence:

1. Two men stand on a gym mat (yellow and red), Man 1 (left) in black shirt/dark pants, Man 2 (right) in black shirt/jeans.

2. Camera zooms in on Man 2, who speaks and uses hand gestures (e.g., fist, clapping).

3. Then, the screen splits into two: left side shows Man 2 demonstrating a technique, right side shows two men doing a footwork drill.

Now, describe chronologically:

- Initially, two men stand on a yellow and red mat; the man on the left wears a black shirt and dark pants, the man on the right wears a black shirt and jeans. They remain stationary as a pair of shoes sits on the mat.

- The camera then zooms in on the man in the black shirt and jeans, who speaks and gestures with his hands.

- Finally, the screen splits to show two smaller clips: one of the man demonstrating a technique and another of two men performing a footwork exercise.

Check rules: a) motion chron

The man in the black shirt is moving his hands and body while speaking. The split screen shows two other scenes (which are not part of the same object motion).

The background (wall and mat) is static. There is no ambient environmental motion (fire, water, smoke, wind).


RAW CAPTION: Got it, let's tackle this. First, I need to describe the video in chronological order. The video has two parts: a sketch on the left and a real-life demonstration on the right. The sketch shows a person from the back with hands gathering hair into a ponytail. Then the real part shows hands working on actual blonde hair, tying it into a bun.

First, the sketch: it's a black and white line drawing of a person with a ponytail being formed. The hands are holding the hair at the nape. Then the real video: hands with light skin, wearing a white shirt, are working on long, light brown or blonde hair. They gather the hair, twist it, and form a bun.

Check the rules: focus on motion and behavior, chronological. So start with the sketch (left side), then the real action. The main subjects are the hands in the sketch and the real hands.

In the real video, the hands are gathering the hair, wrapping it, tightening the bun. The hair is long, light-colored, tied into a ponytail first, then the bun.

Chronological order: The video starts with a sketch of hands forming a ponytail, then transitions to a real demonstration where hands manipulate long blonde hair into a bun.

Spatial relationships: the sketch is on the left, real on the right. Then in the real part, the hands are working on the hair from behind the person.

Background: minimal. The real video shows a bed with yellow sheets maybe, but rule e says minimal unless essential. So maybe just mention the hair is being worked on.

Camera perspective: the real video starts with a close-up of the hair, then the view shifts to show more of the person's back, hands working. Camera movement: maybe from close-up to medium shot.

Wait, the video starts with split screen (sketch and real), then the real part transitions to a single view. So the sequence is: split screen (sketch left, real right) showing hands gathering hair; then the real part shows hands working on the hair, forming a bun, with the person sitting on a bed.

So the caption should describe the actions step by step.

Let's structure it:

- First, the left side shows a line drawing of a person with hands pulling hair into a ponytail at the nape. The right side shows hands with light skin, wearing a white shirt, gathering long, light blonde hair into a ponytail.

- Then, the hands manipulate the hair, twisting and securing it into a bun.

- Camera perspective: initial split screen, then the right side transitions to a close-up of hands working on the hair, then showing the person's back and hands.

Wait, the video has five frames. Frame 0: split screen. Frames 1-2: split screen, right side shows hands working. Frame 3: right side is close-up of hands. Frame 4: wider shot of the person's back with hands working.

So chronological: starts with split screen (sketch left, real right), hands in the sketch are holding hair at the nape to form a ponytail. In the real part, hands with light skin gather long, light blonde hair into a ponytail, twist it, and secure into a bun. The camera starts with split screen, then shifts to focus on the hands working on the hair, then shows the person's back as the hands continue shaping the bun.

Now, following the rules: exclude text recognition, so ignore the "STEP 3" text. Focus on motion.

Main subjects: hands (in sketch and real), hair (blonde).

Chronological: The video begins with a split-screen view: left displays a black-and-white line drawing of hands forming a ponytail from the back of a head, right shows real hands gathering long, light blonde hair into a ponytail. The hands then twist the hair and secure it into a bun, with the camera transitioning from a close-up of the hair to a wider shot revealing the person's back as the hands adjust the bun.

Check rules: focus on motion (gathering, twisting, securing), chronological order. Mention appearance (blonde hair, light skin hands, white shirt). Spatial: split screen then closer to the hands.

Background: minimal, but the real part has a bed (yellow sheets) but maybe not essential. Rule e says minimal unless essential, so maybe skip background.

So final caption:

<caption_output>The video begins with a split-screen view: left side shows a line drawing of hands gathering hair at the nape to form a ponytail, right side displays real hands with light skin working on long, light blonde hair. The hands twist and secure the hair into a bun, transitioning from a close-up of the hair to a wider shot showing the

A person's hands actively manipulate and braid hair, with the hair itself moving due to physical forces from the braiding action.

Background elements (room interior) show no uniform shifting; no fire, water, smoke, or wind present as dominant motions.


Two hands manipulate narrow brown paper strips, folding a new strip to create a corner and then gluing it to adjacent strips. The strips are arranged in a radial fan pattern on a white surface, with the hands positioned centrally. The camera maintains a steady top-down perspective throughout.

Hands are manipulating brown paper strips, folding them to create corners. The strips move as they are folded and glued together, with clear physical interactions between the hands and the paper.

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


The person, wearing blue jeans and brown shoes, sits on the floor with various tools scattered around. They hold a light-colored rock in one hand and a cylindrical wooden tool in the other, adjusting their grip and positioning the tool against the rock. The camera maintains a top-down perspective throughout, capturing the hands and objects in the immediate workspace.

Person's hands manipulate a rock and a cylindrical tool, causing discrete movement of solid objects.

Background elements (red toolbox, shoes, wooden floor) show minimal shift; no fire, water, smoke, or wind present.


A person with light-colored sleeves holds a cloth near a black skillet on a gas burner with blue flames; to the left of the skillet, a white plate holds multiple white potatoes. The person then picks up one potato from the plate and places it into the skillet. The camera remains static, providing a top-down view of the stovetop and surrounding countertop.

A person pours a liquid into a pan, then places eggs into the pan. The eggs and the person's hands are moving.

The background (stove, plate, countertop) is static. The flame is present but not dominant. No camera motion detected.


A man wearing a plaid shirt and glasses stands in an alleyway, turning his head from left to right as he shifts his gaze. He remains near a brick wall with red metal railings in the background. The camera stays mostly stationary, capturing his subtle head movements.

A human subject (man in plaid shirt) exhibits discrete, solid-body motion: head turns, body shifts posture, and slight torso movement across frames.

Background elements (brick wall, red railing, ground) show no uniform shifting; no fire, water, smoke, or wind motion detected. Environment appears static.


The video shows four sequential scenes: a person in a dark shirt with a name tag works at a table with a yellow container and tools; a woman in a white lab coat with a pink hair accessory operates a white machine; another woman in a dark shirt and white apron handles a yellow container and tools; and finally, two women in dark shirts with lanyards work at tables with green bins while a man in a white coat stands behind them. The camera remains static between cuts, focusing on each individual's activity without significant movement.

Two women operating machinery and handling tools; their hands and arms move to manipulate objects on workstations.

Background elements (factory machinery, walls) show no uniform shifting; no fire, water, smoke, or wind effects observed.


A hand grasps a honeycomb frame densely covered with small brown bees, lifting it upward from a beehive. As the frame tilts, bees cling to the hexagonal cells while more bees remain within the hive structure below. Background grass is faintly visible. The camera maintains a close perspective, following the hand’s motion as the frame is raised.

A hand manipulates a beehive frame, causing the frame to move incrementally. Bees are active on the frame but their motion is incidental to the frame's displacement by the hand.

The background includes grass and beehive structures, which remain static throughout the video with no fluid or environmental motion (e.g., wind, water) dominating the scene.


Two toddlers interact with a colorful toy cart; a girl in a white shirt and blue overalls pushes the cart while another girl in a red shirt and blue pants crawls behind her, moving across the living room floor. The cart has a yellow container filled with toys and purple-green wheels. As they move, the camera follows their motion, panning slightly to the right.

Two children (solid objects) are interacting with a wheeled toy containing balls. The child in white actively pushes the toy, causing it to roll, while the child in red moves alongside and interacts with the toy. The toy's motion is due to physical forces from the children's pushing.

The background (couch, wooden table, wicker basket, and wall) remains static with no uniform shifting or fluid motion (fire, water, smoke, or wind). All environmental elements are stationary.


A man in a white t-shirt drinks from a bottle while holding a packet in his left hand; he then stops drinking, turns to his right, flexes his right bicep while still holding the packet, and looks toward the camera. The scene takes place at a table with snacks and a poster visible in the background. The camera remains stationary with minimal movement.

A person (in white t-shirt) moves their head and arm to drink from a bottle, then holds the bottle steady while looking toward the camera. The bottle is the primary moving object controlled by the person's hand.

Background elements (wall, posters, table items) remain stationary with no uniform shifting. No environmental fluids (fire, water, smoke) or wind effects are visible.


RAW CAPTION: Got it, let's break this down. First, the video starts with a view of an outdoor area. There's a person in a green shirt and white hat, maybe bending over. Then another person in a white shirt and dark pants is there. Then, a person in red shoes walks by. Then a person in a black shirt and red cap moves. The camera seems to be moving, maybe panning or adjusting angle. Let's check the rules.

Focus on motion and behavior. Main subjects: people. Chronological order. First, the person in green shirt is there. Then others. Then the person in red shoes walks, then the person in black shirt moves. Spatial relationships: they're in a gravel area, near a concrete path, with trees in the background. Background minimal unless essential. Camera perspective: starts from a window or doorway, then moves? The video shows the camera angle changing, like tilting. Wait, the description says the camera is moving, maybe from a low angle, then panning. Let's structure:

First, the scene shows a gravel area near a concrete walkway. A person in a green shirt and white hat is bending. Then a person in a white shirt and dark pants is near a black grill. Then a person in red shoes walks past. Then a person in a black shirt and red cap moves. The camera angle shifts, maybe from an over-the-shoulder or doorway view, tilting down to show more of the scene.

Wait, the first frame [0.0] has a person in green shirt and white hat bending. Then [1.4] shows a person in white shirt and red cap bending. Wait, the first person might be the same? Wait, the video shows:

[0.0] person in green shirt, white hat, bending. Another person in white shirt, dark pants, red shoes, standing. Then [1.4] the person in green shirt is still there, but the person in white shirt is moving? Wait, the user provided the video frames with their actions. Let's parse the video descriptions.

Looking at the frames:

Frame 0: Person in green shirt, white hat, bending. Person in white shirt, dark pants, red shoes, standing. Background: trees, gravel, concrete path.

Frame 1: Similar, but maybe the person in white shirt is moving towards the person in green.

Frame 2: View from inside a building (window), so camera moves to show through a doorway. Now, the person in green shirt is still there, person in white shirt is moving, another person in black shirt and red cap?

Wait, the rules say: focus on main subjects (people), their motion in chronological order. So:

First, a person in a green shirt and white hat bends over near a gravel area. A second person, wearing a white shirt and dark pants, stands nearby. Then, a third person in a white shirt and red cap moves toward the first person. A fourth person, wearing a black shirt and red cap, walks through the scene. The camera shifts from an outdoor perspective to a view through a window frame, then tilts to capture the moving subjects from a lower angle. The background includes trees and a gravel path, but minimal description.

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

- At the start, a person in a green shirt and white hat bends over on a gravel surface. Nearby, a person in a white shirt and dark pants stands. Then, a person in a red cap and white shirt walks past. Another person in a black shirt and red cap moves through the scene. The camera angles shift, moving from an external view to a view through a window, then tilting downward to capture the subjects.

But need to be precise. Let's check the frame numbers. The frames go from 0 to 5 (the user listed [0.0], [1.4], etc.). The first frame shows a person in green shirt (white hat) bending, another in white shirt (dark pants, red shoes). Then frame 1.4: the person in white shirt is moving, maybe walking. Frame 2.5: view from a doorway (window), so camera is inside looking out. The scene has multiple people moving: one in white shirt with red cap walks toward the person in green, another in black shirt moves. Then camera moves, possibly panning.

The key is chronological motion:

1. Person in green shirt (white hat) bends down.
2. Person in white shirt (dark pants, red shoes) stands and then moves.
3. Person in white shirt with red cap walks through the scene.
4. Person in black shirt (red cap?) moves.
5. Camera shifts to a view from a window or doorway, then tilts.

Wait, the third frame (2.5s) shows the view from inside

A person and a dog are moving (walking/interacting), representing discrete solid objects with clear locomotion.

The background (stone wall, trees, sky) shows no uniform shifting, and there are no fire, water, smoke, or wind-driven motions present.


RAW CAPTION: Got it, let's break this down. First, the video starts with a person on a horse. The person is wearing a red shirt and a cowboy hat. The horse is brown with a white tail, and they're riding through a grassy field with trees in the background. Then, another person joins them, wearing a plaid shirt and also a cowboy hat. They ride up to the first person. Then there's a text screen, but the rules say to exclude text recognition, so we don't mention that.

Chronological order: First, one rider on a horse. Then a second rider joins. Need to describe their appearance: first rider red shirt, hat, horse brown/white tail. Second rider plaid, hat, same horse? Wait, no, the second rider is on a horse? Wait, the video shows two riders approaching. Let's check the frames. Frame 0: one rider. Frame 3-4: two riders, so the second one comes up from behind? Wait, the sequence: starts with one rider (red shirt, cowboy hat) on a brown horse with white legs, moving through the field. Then, a second rider (plaid shirt, cowboy hat) on a horse (maybe same? Or different?) joins, moving alongside. Then they ride together, then the text screen. But we need to exclude text, so stop before that.

Focus on motion: first rider riding, then second rider approaches from behind, joins, they ride together. Appearance: first rider red shirt, cowboy hat, brown horse with white tail and legs. Second rider plaid shirt, cowboy hat, riding a horse (maybe same color? The video shows two riders, so two horses? Wait, in frame 3-4, two riders, so two horses. Let's see: the first rider is ahead, then the second comes up from the background, so spatial relationship: second rider is behind first, then moves to side. Wait, in the video, the first rider is moving, then another rider (second) joins from behind, and they ride together. So chronological: initial rider (red, hat, brown horse) moves through field. Then second rider (plaid, hat, horse) approaches from behind, joins the first rider, and they ride together. Then the text appears, but we don't include that.

Background: grassy field with trees, but minimal. Camera perspective: seems to be a static shot or slight follow? The description says "camera perspective and movement" at the end. In the video, the camera is following the riders, probably a slight pan to keep them in frame. So camera movement: follows the riders, maybe a gentle pan.

Now, structure the caption: chronological order. Start with first rider. Then second rider joining. Describe appearance of each and their motion. Spatial: second rider comes from behind, joins.

Let's draft:

A person in a red shirt and cowboy hat rides a brown horse with white legs and tail through a grassy field, moving from left to right. A second person in a plaid shirt and cowboy hat approaches on a horse from behind, joins the first rider to their left, and they ride together. The camera follows the riders with a slight pan to maintain framing.

Wait, check if the second rider is to the left. In the video, when the second rider comes up, they are behind the first, then move to the left? Let's check the frames. Frame 0-2: one rider. Frame 3-4: two riders. So the second rider is coming from the background (behind the first rider), then joins, so spatial relationship: second rider is behind the first, then rides alongside. The direction: they move across the field.

Wait, the exact sequence: the first rider is moving, then the second rider is seen approaching from behind, so the second rider comes from behind the first rider, and joins. So "a second person in a plaid shirt and cowboy hat approaches on horseback from behind, joins the first rider to their left, and they ride together."

Also, need to mention the appearance of the animals: first horse is brown with white tail (maybe legs?), second horse—do we know? The problem says "briefly describe their appearance and number". So each person's appearance and their horses. The first rider's horse: brown, white tail, maybe white legs. The second rider's horse: maybe similar? But maybe just say "a second person rides a horse".

Wait, the rules say "appearance and number (color, size, orientation)". So for the first person: red shirt, cowboy hat. Horse: brown with white tail. Second person: plaid shirt, cowboy hat. Horse: maybe not specified, so just "rides a horse".

Now, chronological: first, one person rides a horse.

Briefly describe what discrete, solid objects are moving.

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


RAW CAPTION: Got it, let's break this down. First, the video starts with a person in a green shirt and patterned pants snowboarding. They're in mid-air, so that's the initial action. Then they land on the snow. Next, there's another person in a black outfit snowboarding. Then the scene shifts to a person in a green jacket falling down. Then the camera shows a group of people in the distance, including someone in a red jacket. Wait, no, let's check the timestamps.

Looking at the frames:

[0.0] - Person in green shirt (top, snowboarding) jumps over others. Others include a child in brown and a person in black.

[1.4] - Same person lands, now standing. Other people are around.

[2.5] - Person in black snowboarder is moving, then a child in black falls.

[3.6] - Person in green (maybe the same?) is on the snow, and another person in black is walking.

[4.7] - Group of people, including a child in red, in the distance.

So chronological order: First, a snowboarder in green shirt and patterned pants jumps over others, then lands. Then a snowboarder in black (or similar) moves, then another person (maybe the same or different) in green falls. Then the camera shows a wider scene with multiple people, including a child in red.

Wait, the main subjects are snowboarders. Let's list their actions:

1. A person in green shirt and colorful pants snowboards, leaping over others (including a child in brown and a person in black), then lands.

2. Then, another person (or same?) in black snowboards, but maybe the first person is now standing. Wait, [2.5] shows a person in black snowboarder moving, then a child in black falls. Then [3.6] a person in green (maybe the same as initial) is standing, and another in black moves.

[4.7] shows multiple people, including a child in red, on the slope.

Need to describe in chronological order, motions, appearance.

Start: A snowboarder in a green shirt and patterned pants executes a jump over other individuals, including a child in brown clothing and a person in black, landing on the snow. Subsequently, another individual in dark clothing snowboards, while a child in black falls. The scene then shifts to show multiple people in the background, including a child in a red jacket, as the camera pans across the snowy slope.

Check rules: focus on motion and behavior, chronological order. Appearance: colors, sizes. Spatial relationships: in front, etc.

First action: green shirt snowboarder jumps over others (so others are in front, below maybe). Then lands. Then another snowboarder (black) moves. Then a child falls. Then wider view.

Also, the camera movement: starts close, then pans to show more people.

Need to be concise.

Let me draft:

A snowboarder in a green shirt and patterned pants jumps over others, including a child in brown and a person in black, then lands. Subsequently, a person in dark clothing snowboards, while a child in black falls. The camera then pans to reveal multiple individuals on the slope, including a child in a red jacket.

Check if spatial: first the green snowboarder is over others (so others are below), then when landing, they're on the snow. Then the dark-clothing snowboarder is moving, and the child in black falls.

Also, mention number: multiple people, but main subjects are the snowboarders.

Let's make sure it's chronological:

- First frame: green snowboarder mid-air, others around (child in brown, person in black).

- Second frame: green snowboarder lands.

- Third frame: person in black snowboards, child in black falls.

- Fourth frame: green snowboarder (maybe now standing), another in black moving.

- Fifth frame: group of people in background, child in red.

So the main motions:

1. Green snowboarder jumps over others (so their position is above, others below) and lands.

2. Then a person (black clothing) snowboards, and a child (black) falls.

3. Then the camera shows more people, including a child in red.

Need to keep it concise.

Final caption:

A snowboarder in a green shirt and patterned pants leaps over a child in brown and a person in black, landing on the snow. A person in dark clothing then snowboards while a child in black falls, followed by the camera panning to show multiple individuals, including a child in red, on the slope.

<caption_output>A snowboarder in a green shirt and patterned pants

A person in a green jacket snowboards down a slope, a child moves across the snow, and both interact with the environment (e.g., the child falls). These are distinct solid objects undergoing locomotion and collisions.

Background elements (trees, snow-covered ground) show no uniform shifting or fluid motion; no fire, water, smoke, or wind effects dominate.


Three men in black shirts sit at a table; the middle man raises a glass to drink, lowers it, and places it on the table, then holds a bottle while the left man holds a glass and the right man holds a bottle. The camera remains static with minimal background elements visible.

The three individuals are moving their arms (drinking, lowering glasses) and heads (talking). These are solid, distinct objects moving due to their own physical actions.

The background wall and bottles are static with no shifting or fluid motion. No fire, water, smoke, or wind is present.


A man in a blue shirt and dark shorts stands at the edge of a blue above-ground pool, pushing a red and yellow inflatable raft into the water. He steps into the pool, causing splashes, while the raft floats within the circular pool. The scene occurs outdoors with a white fence and house in the background; the camera maintains a stationary top-down perspective throughout.

A person (discrete object) is actively moving within the pool, interacting with a yellow floating object; the person's motion is distinct and driven by physical actions (e.g., reaching, lifting, and manipulating the object).

Background elements (white fence, building, trees) remain static with no uniform shifting, and water movement in the pool is secondary to human interaction.


A person holds a small gray, roughly shaped stone above a white paper with scattered light brown powder, manipulating the stone with their hands while a wooden-handled tool rests on the paper in front of them. The stone is moved over the powder, and the person adjusts its position with both hands. The scene is observed from a top-down perspective with steady camera movement, focusing on the workspace.

Hands and clay object are moving: hands mold and manipulate clay, place tools, and shift the clay's position on the surface.

Background elements (desk, computer, stacked papers) are stationary with no uniform shifting. No fire, water, smoke, or wind observed.


A person in a light blue shirt and dark pants stands on a grass-lined sidewalk near a purple bicycle with white wheels lying on the pavement. They bend down, grasp the bike's handlebars, lift them slightly, and step back, causing the bike to shift position on the pavement. The camera remains at ground level with minimal movement, capturing the action from a static perspective with slight shake.

The person (discrete object) is adjusting the bicycle (another discrete object) by bending down, touching the handlebars, and stepping back. The bicycle is moved slightly by the person's actions.

No shifting background elements. No fire, water, smoke, or wind observed. Background remains static.


A person wearing a green T-shirt stands in a narrow hallway, positioned between a magnet-covered refrigerator to their left and cabinets to their right. They gradually move forward, leaning slightly toward the camera over the sequence. The camera remains fixed in a medium shot with no movement.

A person is moving slightly: head turning and mouth movements while speaking.

The background (refrigerator, door, wall decorations) is static and shows no shifting. There are no signs of fire, water, smoke, or wind.


A person wearing a light-colored cap, long beard, and dark shirt is centered in the frame, raises both hands to their head, causing a mirrored duplication effect, then lowers their hands to return to a single image. The background consists of vertical blinds, and the camera remains static throughout.

A single person (the man) is moving his hands in a gesture (lifting and covering his face). The mirrored effect duplicates the movement, but the motion originates from the person's discrete physical actions.

The background consists of static vertical blinds with no shifting motion. There is no fluid or environmental motion (fire, water, wind) present. The mirrored effect is a fixed post-processing artifact, not environmental motion.


A man in a brown dog-print shirt, dark jeans, red sneakers, and red cap approaches a seated boy in a red shirt on a waterfront dock. The man gestures with open hands, bends toward the boy, then turns and walks away along the paved path. The boy remains seated with a black bag and yellow gloves nearby. The camera captures the interaction from a slightly low angle, maintaining focus on the man and boy as he moves, with minimal background details.

Two distinct solid objects (adult and child) exhibit motion: adult gestures, bends, and walks; child interacts with adult and moves slightly. These motions are due to explicit locomotion and physical interaction.

Background elements (pier, water, distant bridge) show no uniform shifting; water appears calm with no significant fluid motion (no waves, currents, or wind effects visible).


A man in dark clothing bends over a colorful kite lying on grass near a body of water, adjusts it, then stands and walks away carrying the kite. Other kites are visible in the water. Camera remains stationary, capturing the scene from a fixed angle.

Person (wetsuit) moves: bends over, stands, walks around, and interacts with large flat object (likely a board). Discrete solid objects with explicit locomotion and interaction.

Grassy field, distant water, and sky show minimal motion. Water has gentle ripples but no dominant fluid motion; background elements (grass, structures) remain stable with no uniform shifting.


A hand uses a fork to mix a yellowish breading mixture in a rectangular tray. To the right, a white plate holds several flour-coated pieces. The camera remains in a top-down position, capturing the stirring motion and the nearby plate.

A hand holding a utensil is mixing a batter in a container; the motion is due to the hand's deliberate action.

The background (kitchen counter, plate, container) is static and shows no shifting. No fluid or environmental motion (fire, water, wind) is present.


Two men push a large white refrigerator on a wheeled cart along a sidewalk; one wears a gray plaid shirt and brown pants, the other a dark coat. A person in a blue jacket operates a red mobility scooter positioned beside the cart. As they move forward, a car passes in the foreground. The camera remains stationary, capturing the scene from a street-level perspective.

Discrete objects: a person pushing a cart with a white board, a person in a wheelchair, a walking person, and moving cars. The person pushes the cart along the sidewalk, and cars drive by on the street.

The background (building, street) is stable with no fluid or environmental motion (e.g., fire, water, smoke, wind).


A man in a blue and yellow striped shirt bends over a sink, using a hose to rinse his hands, then straightens up and turns toward the mirror to pick up a white cup. The camera shifts angles to follow his movements, capturing close-up actions at the sink with minimal background detail.

A person in a blue/yellow striped shirt moves their head and hands near a sink, interacting with objects on the counter.

Background elements (windows, counter items) show no uniform shifting; no fire, water flow, smoke, or wind observed.


A human hand gently moves across the sandy bottom of an aquarium, with several small orange fish and a larger yellow fish swimming around it; the hand shifts slightly left and right as the fish dart in various directions, while the camera remains stationary, focusing on the interaction within the tank.

Fish are visible moving through the water, exhibiting discrete locomotion (swimming) as distinct solid objects.

The aquarium background (walls, gravel) shows no uniform shifting, and while fish swim, the water itself is still with no dominant fluid flow; thus, not primarily ambient environmental motion.


Close-up of mechanical components, then a hand adjusts parts on the machine. The camera shifts to a man in a dark uniform and cap operating machinery to the left of a person in a light-colored shirt, who observes while the man manipulates controls; the camera pans left to reveal additional workers around the machinery.

Metal parts of a machine moving mechanically in the first scene; a man and woman operating a typesetting machine (moving parts and sheets) in the second scene.

No shifting backgrounds or fluid/environmental motion observed. Background elements (machine frame and office walls) are static.


Two men in white shirts play violins while seated side by side, with the left man wearing a dark tie; they move their bows across the strings, maintaining positions in front of music stands, in a room with a wooden door visible in the background. The camera remains static throughout.

Two violinists and their violins/bows are moving: hands and arms moving to play the violin.

Background elements (wall, door, painting) are stationary. No fire, water, smoke, or wind observed.


The video opens with a black screen. A person in a white shirt manipulates a small glass, placing it near a table with a blue pen, a metal tool, and a book. Their hands adjust the glass's position on the table. The camera maintains a close-up, slightly shaky perspective focused on the hands and tabletop.

A person's hands (discrete solid object) interact with a jar, demonstrating pouring motion; the jar and hands are the primary moving entities due to physical manipulation.

The background contains static objects (book, pens, container) with no shifting or fluid motion; no fire, water, smoke, or wind observed.


A brown goat with small horns stands in a metal wire enclosure, facing the fence. A human hand extends through the bars from the right, offering food to the goat, which eats from the hand. The goat then turns its head slightly to the left, while the hand retracts. The camera maintains a steady frontal view of the interaction.

The goat moves its head and body to eat from the human hand. The hand moves slightly to deliver food. Both are solid objects exhibiting discrete motion from physical interactions (feeding) without fluid or camera-induced effects.

The background (grass, dirt ground, and metal fence) is static with no signs of fluid motion (fire, water, smoke) or environmental sway. Background elements remain fixed without uniform shifting.


Three men in dark shirts (one wearing a blue cap) sit around a chessboard on a table, engaging in animated discussion; the man on the left gestures with his hands toward the board, the man on the right points at the board while speaking, and the man in the middle maintains a relaxed posture with arms crossed, all interacting with the chess pieces; the camera remains stationary in a top-down view throughout the sequence.

Three people are moving their hands and arms, and cards are being moved on the table due to the game interaction.

The background (brick wall) is static with no signs of ambient environmental motion (fire, water, smoke, wind).


A man in a black shirt and jeans stands beside a white bicycle inside a store, using a key to adjust the front wheel brakes. He moves the key to tighten or loosen the brakes, focusing on the handlebar area. The scene is set in a retail space with other bicycles visible in the background. The camera remains stationary, capturing the man's actions from a frontal perspective.

A person standing next to a bicycle exhibits subtle posture shifts (e.g., arm adjustments, slight torso movement) while interacting with the bike. Other objects (bikes, people in background) are stationary.

Static background elements (red banner, other bikes, walls) show no uniform shifting. No fire, water, smoke, or wind-driven fluid motion observed.


A child in blue overalls sits on a carpeted floor, surrounded by scattered LEGO pieces, a red toy car, and small figures. Initially leaning forward, the child sits upright, picks up a blue LEGO piece, and moves it toward a blue plastic sheet. They then grasp a black toy and adjust its position. The LEGO City box (labeled for ages 5-12) remains to the right, with toys spread across the floor. The camera maintains a static, top-down view with a slight shake.

The child's hands and Lego pieces exhibit discrete motion: hands manipulating pieces, assembling, and relocating toys. These are solid objects moving due to direct physical interaction (e.g., grasping, dropping, placing).

The background (fireplace, couch, walls) shows no shifting or fluid motion. No fire, water, smoke, or wind is present; environmental elements are static.


A man in a light gray suit, blue shirt, and green/blue striped tie sits in front of a brick wall, holding a wine glass. He leans forward, bringing his right hand up to cover the camera lens briefly, then lifts the wine glass to his mouth to take a sip. The camera transitions from a medium shot to a close-up during the action.

The man is moving his head and hand (to drink from the glass). The glass is being raised to his mouth and then lowered.

The background is a static brick wall with no shifting or fluid motion. No fire, water, smoke, or wind is visible.


A person in a light blue shirt and white gloves manipulates a silver rectangular metal strip, moving it toward a machine component with both hands. They adjust the metal piece, positioning it near the machine’s mechanism while the strip rests on the machine’s surface. The camera maintains a fixed side-angle perspective throughout the sequence.

A person in a blue shirt and white gloves manipulates a metal rod, moving their arms and hands to interact with the machinery and handle the rod.

The background (machinery, metal rods, workshop elements) is stable with no uniform shifting or fluid/environmental motion (e.g., no fire, water, smoke, or wind).


A person in a plaid shirt holds a ukulele with a blue headstock and green body, using their left hand to press frets on the neck while their right hand adjusts string positions; the hands move sequentially across the fretboard, with the camera maintaining a static close-up on the instrument and hands throughout.

A person's hands are moving to play a ukulele, with discrete motions (fingers pressing strings, strumming).

The background is a static plain wall with no shifting or fluid motion (fire, water, smoke, wind).
