A person wearing a light blue shirt tightens lug nuts on a silver wheel, then adjusts the valve stem to face outward. The camera maintains close-up shots from a top-down perspective, focusing on the wheel and hands.

A person's hands manipulate a tire valve stem and tool to tighten wheel bolts, causing discrete motion of the hand-tool-tire interaction.

No shifting backgrounds or fluid/environmental motion observed; static elements (car wheel, tire, tool) remain stable with no wind, water, or smoke effects.


A man in a black vest over a white shirt and dark pants dances closely with a woman in a black top, patterned leggings, and sandals on a red-lit dance floor. They move rhythmically, stepping and swaying as they navigate through other dancers. The camera follows their motion with slight handheld movement, maintaining focus on the pair as they interact in the crowded space.

Discrete people (dancers) are moving with coordinated locomotion, exhibiting distinct bounding box movements due to physical forces (muscle-driven motion).

The background (walls, floor, and fixed lighting) shows no uniform shifting or fluid motion. No fire, water, smoke, or wind is present in the scene.


Two girls sit side by side; the left girl (blonde hair, sleeveless top) holds a phone and gazes downward, while the right girl (brown hair, patterned top) lifts her head upward, smiles, then lowers her head again. The background features a stroller with a cover and miscellaneous items. The camera remains static in a close-up view.

Two human subjects exhibit motion: one holds a device while the other shifts head/body posture and direction of gaze.

Background elements (chair, blanket, window) remain static across frames; no fluid or wind-driven motion (fire, water, smoke) observed.


RAW CAPTION: Got it, let's break this down. The video starts with two kids in a snowy yard. First, there's a child in a red jacket and black pants, and another in a black jacket with a white hood. Then the camera moves, showing more kids. The child in red is playing in the snow, maybe building a snowman or digging. Another kid in red is on a sled? Wait, the first frame shows a child in red and black. Then the next frame has a kid in red on a sled maybe. Then the child in black is standing. The child in red is moving through the snow, getting up. Then the child in red is standing up, looking around. The camera seems to follow the movement. Let's check the chronological order.

Frame 0: Two kids in snow. Red jacket, black pants, and black jacket with white hood (maybe a hat). Background is a house, snow.

Frame 1: More kids? Wait, the first frame is [0.0], then [1.4] shows another child in red on a sled? Wait, the description says: [0.0] has two kids. [1.4] shows two kids: one in red (with "G" maybe) on a sled, and the other in red (hooded) digging. Then [2.5] shows the red hooded kid standing, and the other in red is on a sled. [3.6] shows the red hooded kid moving, and the other in red is on the left, maybe. [4.7] shows the red hooded kid standing, and the sled kid is gone. So the main subjects: two kids in red, one in black.

Chronological: First, two kids in the snow. Then the camera shifts to show a red-jacketed child on a sled (maybe) and another in red digging. The red-digging kid stands up, moves through snow, then the camera follows them as they move around the yard. The black-jacketed kid is standing in the background initially.

Appearance: Two children in red jackets (one with a hood, one with a red jacket), one child in black jacket (hooded, white hat maybe). Spatial: The red-hooded kid is moving, the black kid is in the background. Camera movement: The camera follows the red-hooded child's movements, slight shift.

Background: Snow-covered yard, house in the background. Minimal description.

So structure the caption:

Start with the first scene: two children playing in deep snow. One in red jacket and black pants, another in black jacket with white hood. Then the camera moves to show a red-jacketed child on a sled (but maybe just the red kid moving), the red-hooded child digging, then standing, moving through snow. The black kid is in the background. Camera follows the red-hooded child.

Wait, the rules: concise, chronological. Let's outline:

- Initial frame: two children in snow. One in red (hooded, pants black), one in black (hood, white hat?).

- Then the camera shifts, showing the red-hooded child digging in snow, then standing, moving.

- The black child is in the background.

- Camera perspective: follows the red child's movement, slight shake.

Need to be concise. Let's write:

A child in a red hooded jacket and black pants digs in deep snow, while another child in a black jacket stands in the background. The camera shifts to follow the red-jacketed child as they move through the snow, briefly showing another red-jacketed child near a sled before focusing on the first child rising and walking away. The scene occurs in a snow-covered yard with a house visible, and the camera maintains a steady follow movement with slight shake.

Wait, check rules:

a) Motion: digging, moving, standing, walking.

b) Appearance: two kids, red hooded, black jacket.

c) Spatial: background black kid, red kid moving.

d) Camera: follows, slight shake.

e) Background: minimal (house, snow-covered yard).

f) No text, names.

So put together:

Two children play in deep snow: one in a red hooded jacket and black pants digs, then stands and walks; another in a black jacket stands in the background. The camera follows the red-jacketed child's movement as they navigate the snow, briefly showing a second red-jacketed child near a sled before focusing on the first child moving away. The scene occurs in a snow-covered yard with a house, and the camera maintains a steady follow perspective with slight shake.

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

"Two children in red jackets and black pants play in deep snow. One digs, then stands and moves through the snow while the other

Discrete solid objects (children) are moving: one child in red is interacting with a snow structure, another child in dark clothing stands and then moves, and a third child in red appears and moves.

The background (house, trees) is static and does not shift uniformly. There is no significant ambient environmental motion (like fire, water, or wind) dominating the scene; the snow is stationary on the ground.


A man in a white and blue striped shirt sits to the right of a stainless steel machine with a glass bottle containing a brown liquid and an empty glass jar on its counter. He turns his head toward the machine, then uses his right hand to pick up the empty glass jar, lifting it slightly. The background includes stacked blue containers and wooden boxes. The camera remains stationary.

A person manipulates a small container/object on a lab table, with visible hand movements and object repositioning due to deliberate actions.

Static background elements (chair, equipment, boxes) show no uniform shifting; no fire, water, or smoke present, ruling out ambient motion.


A person in dark clothing walks from the right side of the frame toward the left, moving in front of wooden tables and benches under two bright overhead lights. The camera remains stationary throughout, capturing the motion from a fixed angle.

A person is moving across the scene from right to left, exhibiting locomotion (walking) with distinct bounding box tracking.

Background elements (benches, building, lights) show no shifting or uniform motion. No fire, water, smoke, or wind motion detected; environment appears static.


A person in a red shirt plays a drum set, using drumsticks to strike the snare drum and cymbals rhythmically. The individual alternates between hitting the drumheads and cymbals, moving the sticks in a coordinated manner. The drum set, featuring multiple drums and cymbals, is positioned in front of the person against a dark curtain backdrop. The camera remains fixed with slight movement throughout the sequence.

Drummer (solid human object) actively moves arms/hands to strike drumsticks against drums; drumsticks and drumheads exhibit collisions and translational motion due to physical force application.

Background consists of static black curtain with no fluid, gaseous, or environmental motion (e.g., fire, water, wind).


A person in black athletic wear performs a prone exercise on a dark surface, extending their arm upward while interacting with a yellow strap. The camera begins with a close-up of their torso and shifts to a wider angle showing the full body in motion, maintaining a top-down perspective with slight camera movement.

A person in black athletic wear is performing push-ups, showing controlled movement of the arms and torso. The motion is due to physical exertion.

The background is static and dark with no visible environmental elements (fire, water, wind, etc.). No shifting background elements observed.


A person in a red sweatshirt handles a bag of items on a blue table, moving the bag and adjusting its contents. Another individual in a gray jacket works with clear containers in the background. The person in red leans forward, examining the table's contents. The camera remains mostly steady with minimal movement.

Person in red hoodie manipulates a sandwich (solid object movement), while the person in gray hoodie remains stationary.

Background elements (shelves, walls) are static; no fluid or environmental motion (e.g., fire, water, wind) observed.


A person wearing blue jeans, dark shoes, and a white glove on one hand crouches on a tiled floor, holding an ear of corn with both hands. They twist and pull kernels from the corn cob, causing small yellow kernels to scatter onto the floor. The camera maintains a top-down perspective, focusing on the hands and the corn during the process.

A person wearing gloves manipulates a white, malleable object (likely dough or clay) using a tool (knife-like instrument). The object undergoes discrete deformation through manual cutting and shaping motions.

The background consists of a static tiled floor with no fluid motion (fire, water, smoke) or wind-driven effects. Background elements (floor tiles, person's legs) remain fixed and unshifted.


A man in a beige sweater and blue jeans stands in a kitchen, holding a glass. The scene transitions to a low-angle shot of a gray vacuum cleaner with blue lights being pushed across a tiled floor by a person wearing black heels, moving rightward while the camera follows the vacuum’s motion as the person steps away.

The person (wearing blue pants and pink lower body) is actively pushing a vacuum cleaner across the tile floor, with the vacuum cleaner moving as a distinct solid object.

Static background elements (cabinets, rug, chairs) show no uniform shifting or fluid/environmental motion (no fire, water, smoke, or wind effects observed).


RAW CAPTION: Got it, let's break down the video. First, the main subject is a person crouching in a grassy area. They're wearing a blue shirt and blue pants, I think. The video starts with them crouching, then there's a transition where the scene is overlaid with a pink and white filter maybe? Wait, the frames show the person moving, maybe getting up? Wait, the first frame has them crouching, then the next frames have a distorted effect with a frame inside a frame. Then the person seems to be moving, maybe standing up. Wait, no, the first frame is [0.0] showing the person crouching, then [1.0] has a blurred frame with the person still, then [2.0] is the same person in the grass. Wait, maybe the video shows the person in a crouched position, then the camera has some effects like a frame inside a frame, then a blur, then a fade. But the main motion is the person crouching in the grass. Let's check the rules. Focus on motion and behavior chronologically.

First frame: person in blue shirt and pants crouching on grass. Then maybe a transition where the video has a glitch effect (like a frame within a frame), then the person continues to move? Wait, maybe the person is moving towards the camera or shifting position. But the description says "concise, chronological paragraph". Let's list the events in order.

Frame 0: Person crouching in grass, blue top and blue pants, background has trees and bushes.

Frame 1: Video has a distorted frame within frame, person still crouching but the image is glitched.

Frame 2: The frame is overlaid with pink and white strips, person crouching.

Frame 3: The pink strips continue, maybe person is slightly moving.

Frame 4: The pink strips dominate, person is now lying down or falling? Wait, the video description says "crouching" but maybe they get up. Wait, no. Let's check the original frames:

The first frame [0.0] shows a person crouching. Then [1.0] has a black border around a smaller frame of the same person crouching. Then [2.0] is the person in the same position but with a pink overlay. Then [3.0] is more pink, maybe the person is moving. Wait, but the main behavior is the person's movement.

Wait, maybe the person is crouching, then the camera applies some effects (like frame within frame, color shifts), and then the person continues to be in the same position but the video has these visual effects. But according to the rules, focus on motion and behavior of main subjects. So the main subject is the person, who is crouching in grass. The video has visual effects like distorted frames, color overlays, but the person's action is crouching. Then perhaps the person stands up? Wait, the description says "a person crouching". Let's see:

The first frame: person crouching on grass. Then, in frame 2, the scene is blurred with a frame within frame. Then frame 3: pink overlay. Frame 4: more pink, maybe the person is moving.

Wait, maybe the person is crouching, then the camera effect makes it look like they're moving, but the actual motion is crouching. Wait, but the problem says "chronological paragraph describing the provided video".

Let me re-read the rules. a) Focus on motion and behavior of main subjects in chronological order.

Main subject: a single person (blue shirt, blue pants) crouching on a grassy area. The video starts with them crouching, then there's a visual effect where the image is distorted (like a frame within a frame), then the image is overlaid with pink and white, and then the person's position changes? Wait, maybe the person is lying down in one frame? Wait, the original description: first frame shows person crouching. Then in frame 1, black borders with a smaller frame, frame 2: person crouching with pink overlay, frame 3: pink, frame 4: pink and the person is lying down? Wait, no, the user provided the frames:

[0.0] shows person crouching.

[1.0] shows a black border around a smaller frame of the person crouching.

[2.0] person crouching with pink overlay.

[3.0] more pink, person still crouching.

[4.0] more pink, person moving?

Wait, but the user says the video is [0.0] to [4.0]. Let's think of the chronological order.

0.

Briefly describe what discrete, solid objects are moving.

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


In a workshop, two individuals in white protective gear and masks work at a wooden workbench. The foreground person, wearing a striped white sweatshirt, uses a handheld tool to grind a metallic frame, generating bright sparks, then shifts position and tool while continuing the task. The background individual, dressed in a plain white top, stands to the right, observing. The camera remains stationary with a slight shake, capturing the scene from a fixed angle.

The person (wearing protective gear) is actively manipulating a welding tool on metal beams, producing sparks. The tool and metal beams exhibit discrete motion due to physical interaction during welding.

Background elements (walls, equipment) show no uniform shifting or fluid motion; no fire, water, smoke, or wind observed as dominant phenomena.


Two hands use a wooden spoon and metal spoon to mix a vibrant salad in a rectangular brown bowl, stirring corn, diced avocado, tomatoes, and herbs in a circular motion. The hands move the utensils to combine ingredients, with a plate of crackers visible to the right of the bowl. The camera maintains a top-down perspective, slightly adjusting to follow the mixing action.

Hands actively stirring a salad with a wooden spoon and metal spoon; salad ingredients (corn, peppers, meat) move due to manual mixing.

Static background elements (black table, brown bowl, crackers) show no uniform shifting or fluid/environmental motion (e.g., fire, water, smoke, wind).


RAW CAPTION: Okay, I need to generate a concise, chronological paragraph for this video. Let me watch the frames again.

First, the video starts with a group of people standing. There's a person in a yellow shirt, another in white with a cap, and others. Then, a person in a white shirt and cap starts to move. They bend down, maybe picking something up. Then another person in a dark shirt and shorts approaches, possibly interacting. The person in white seems to be crouching or sitting. Then the dark-shirted person moves towards them. The camera is shaky, maybe handheld.

Wait, the key is to list the actions in order. So start with the group standing. Then the person in white bends down. Then another person (dark shirt) moves into the frame. Maybe they interact. The background is a street with some buildings and chairs, but I should keep background minimal.

Check the rules: focus on motion, chronological, appearance (colors, numbers), spatial relationships, camera perspective. Exclude text, named characters.

Let me outline:

- Group of people standing (yellow shirt, white shirt with cap, etc.)
- Person in white shirt and cap bends down, possibly picks up something.
- Person in dark shirt and shorts moves towards the center.
- They interact, maybe a physical interaction like a tackle or a push.
- The person in white falls or is pushed to the ground.
- The dark-shirted person steps back or moves away.
- Camera is shaky, close-up on the action.

Need to check the frames. First frame: people standing. Second: person in white bends. Third: person in dark shirt moves. Fourth: they're closer. Fifth: person in white is on the ground. So chronological order: people standing, person in white bends, another person approaches, interaction leading to the person falling.

Wait, in frame 0, the group is standing. Frame 1, the person in white (with cap) is moving forward. Then frame 2, they bend down. Frame 3, the dark-shirted person is moving towards them. Then frame 4, the person in white is on the ground. So sequence is:

1. Group of people standing, including person in yellow shirt, white shirt with cap, and others.

2. Person in white shirt and cap bends down, possibly to pick up an object.

3. Person in dark shirt and shorts moves forward, approaching the person in white.

4. The person in dark shirt and shorts interacts with the person in white, causing them to fall to the ground.

5. The person in dark shirt steps back.

Now, spatial relationships: person in white is in front of the group, dark-shirted person comes from the right or left? Looking at the video frames, the person in white is in the center. The dark-shirted person moves from the right towards the center. So "person in dark shirt approaches from the right".

Also, the camera is shaky, close-up.

Let me check the exact details. The caption should mention the number of people. The video shows a group, but exact count? Probably not necessary. The main subjects are the two people interacting.

Wait, the problem says "briefly describe their appearance and number". So for example, "a person in a white shirt and cap, and another in a dark shirt and shorts".

Also, "conclude with the camera perspective and movement (e.g., top-down, pan left, slight shake)."

In this case, the camera is likely handheld, shaky. The movement might be slight shake.

Now, putting it all together:

A group of people stand on a sidewalk, including a person in a yellow shirt, a person in a white shirt and cap, and others. The person in white bends down, then another person in a dark shirt and shorts moves forward to interact, causing the first person to fall to the ground. The camera remains close and slightly shaky throughout the action.

Wait, the chronological order: first the group stands, then the person in white bends, then the dark-shirted person approaches, then interaction leading to the fall. The caption should note each step.

Check for minimal background. The background is a street with chairs, but maybe not necessary. The rules say "minimize background unless essential". So maybe just mention sidewalk.

Wait, in the rules: "exclude text recognition, named characters or stylistic analysis." So don't mention specific things like the yellow shirt color, but maybe the color is part of appearance. But the example says "color, size, orientation" for appearance. So yes, mention colors as part of appearance.

Let me rephrase:

<caption_output>A group of people stands on a sidewalk. A person in a white shirt and cap bends down, then a person in a dark shirt and shorts moves forward to interact, causing the first person to fall to the ground. The second person steps back

Discrete solid objects (people) are performing physical movements: a person executing a handstand transition, another performing a cartwheel, and others interacting through physical contact (e.g., pushes, falls).

Background elements (ground, distant structures) show no uniform shifting or fluid motion. No fire, water, or smoke present. Static background with people standing in place.


A bald man in a dark shirt holds a small baby wearing a striped outfit. The baby, gripping a blue toy, looks around and shifts position while the man supports them. The baby’s head turns and body moves slightly, remaining in front of the man. The camera remains steady, capturing the interaction against a backdrop featuring a curtain.

The man and baby are moving: the man is making slight head and body movements, and the baby is moving its head and arms. These are discrete, solid objects moving due to their own locomotion.

The background (wall and corrugated curtain) shows no significant shifting or environmental motion (e.g., no fire, water, or wind).


The video begins with a person in a dark hoodie with a colorful design holding a camera at chest level, recording themselves. It then cuts to another individual wearing a blue shirt, dark pants, and white sneakers, lying on a tiled floor in front of a couch with pink cushions; the person bends forward, lifts their legs, and shifts their body. The camera remains static in both segments.

A person is moving on the floor (crawling/pushing self) with discrete physical motion; no other significant solid objects exhibit motion.

Background elements (couch, pink cushions, floor tiles) show no uniform shifting; no fluid/environmental motion (fire, water, wind) observed.


A person with long hair wearing a zebra-patterned top with white sleeves uses a hairdryer and brush to style the dark hair of a seated individual with a blue hair clip, who is draped in a black cape. The stylist moves the hairdryer and brush through the client's hair in a continuous motion, adjusting the hair with their hands. The camera maintains a top-down perspective throughout, capturing the stylist’s actions from behind the seated client against a background of wooden flooring and minimal furniture.

A person (stylist) is moving a hairdryer and their hands to style another person's hair; the hair and hairdryer exhibit motion due to explicit physical actions.

The wooden flooring and furniture in the background show no uniform shifting or fluid motion; no fire, water, smoke, or wind is visible.


RAW CAPTION: Got it, let's tackle this. First, I need to watch the video description and generate a caption. The video shows a fencing match. Let's see the sequence.

In the video, there are fencers. They're wearing white gear, masks, and fencing swords. The main action is two fencers moving around a box (maybe a scoring box). Let's break down the timeline.

Frame 0: Two fencers in white, masks, swords. One is lunging, the other is moving. There's a box in the middle. Other people in the background.

Frame 1: One fencer (left) is in motion, maybe retreating. The other fencer (right) is advancing towards the box. The box is central.

Frame 2: Left fencer moves left, right fencer steps forward. The box is still there.

Frame 3: Left fencer sprints left, right fencer stays near the box.

Frame 4: Left fencer continues moving left, right fencer moves right, then left fencer stops. The box is still in the middle.

Frame 5: Left fencer is further left, right fencer is moving left past the box. They're still on the fencing strip.

Now, the main subjects are the two fencers. They're in white uniforms, masks, fencing swords. Number: two fencers. Their actions: they're lunging, moving left and right, around the box.

Spatial relationships: the box is in the center of the fencing strip. The fencers are moving around it. One fencer is to the left of the box at times, the other to the right.

Camera perspective: the camera is following the action, maybe panning slightly? The video description says "camera perspective and movement" so need to check. The frames show the camera moving as the fencers move, so probably a slight pan following the action. Also, the background has other people (spectators, officials) but minimal description.

Rules: focus on motion and behavior in chronological order. Appearance: white uniforms, masks, swords. Number: two main fencers. Spatial: box in center, fencers moving around it.

Conclude with camera: the camera is capturing the action with a slight pan following the fencers, maybe a slight shake as it moves.

Now, structure the caption:

- Start with the main subjects: two fencers in white uniforms and masks, each holding fencing swords.

- Chronological order: They move around a central box. One fencer lunges, the other retreats. Then they both move left and right, circling the box.

- Mention spatial: the box is centrally located on the fencing strip.

- Camera: the camera pans left to follow the fencers' movements, showing their motion across the strip.

Check rules:

a) Motion and behavior in order: yes.

b) Appearance and number: two fencers, white uniforms, masks, swords.

c) Spatial: box in center, fencers moving around it.

d) Camera: pans left, slight movement.

e) Background minimal: just mention that there are other people in the background but don't detail.

f) Exclude text, names, etc.: correct.

Now, draft the caption:

Two fencers in white uniforms and masks, each wielding fencing swords, engage in a match on a striped fencing strip. Initially, one fencer lunges forward while the other retreats toward a central wooden box; they then circle the box, moving left and right as they advance and retreat. The fencers maintain proximity to the box, with one repeatedly moving to its left and the other to its right. The camera pans left to follow their motion across the strip, capturing their dynamic movements with a slight shake.

Wait, check if it's chronological. Let's check the frames:

Frame 0: two fencers moving around box.

Frame 1: left fencer lunges, right fencer moves forward.

Frame 2: left fencer moves left, right fencer steps forward.

Frame 3: left fencer sprints left, right fencer stays.

Frame 4: left fencer moves left, right fencer moves right.

Frame 5: left fencer moves left, right fencer moves left.

Wait, maybe the motion is two fencers moving around the box, one going left and the other right. But need to describe chronologically.

Alternatively: Two fencers in white gear and masks engage in a match on an indoor fencing strip. The fencers circle a central wooden box, with one moving left and the other right; one lunges forward while the other retreats, then they continue circling the box. The camera pans left to follow their movements, maintaining focus on their dynamic motion.

Check for concise. Need to be chronological.

Let me try:

Two fencers in white uniforms and masks, each holding fencing

Two fencers in gear move dynamically around a wooden box, pushing and maneuvering it; their motion is driven by explicit physical forces (pushing, pulling) and locomotion.

Background elements (walls, basketball hoop, distant individuals) show no uniform shifting or fluid motion; no fire, water, or wind effects observed.


A person wearing brown pants, black shoes, and red gloves places a beige textured rug on a wooden floor. They step onto the rug, then kneel to smooth and adjust its position, ensuring it lies flat against the wall. The camera transitions from a close-up of the rug's edge to the person's feet, then to their hands adjusting the rug, concluding with a wider shot of the fully laid rug on the floor.

The person (with red gloves) is moving the carpet by stepping, kneeling, and lifting; the carpet is being manipulated by physical forces.

The background (carpet, wooden floor, and wall with pattern) does not shift uniformly; no fluid or environmental motion (fire, water, smoke, wind) is present.


A person wearing a black sequined crop top and turquoise pants adjusts a flowing turquoise fabric, moving their arms to position the fabric across their torso while revealing their midsection; the background is a plain light pink, and the camera remains stationary in a mid-section shot.

A hand holding a black marker adds orange to a character's foot in a sketch, then shifts to draw dark ink on the character's face and body. The sketch features two figures: one with spiky hair and a fish-like tail, positioned to the left, and a muscular character to the right. The hand moves fluidly across the paper, filling in details. The camera maintains a close-up, static perspective focused on the drawing process against a plain background.

A hand holding a pen is actively moving across the paper to draw, with the pen's tip making contact with the paper surface in discrete, localized motion.

The background (white paper surface) shows no uniform shifting or fluid motion. There are no fire, water, smoke, or wind elements present.


A man in a blue and black checkered shirt holds an orange microphone. A woman in a dark top with a light jacket enters from the left, approaches him, takes the microphone, smiles, and gestures with it while standing to his right. He then steps back. The background includes a wall with a paper. Camera remains static.

Two people (man and woman) interact: man holds a microphone, woman takes it briefly, and both exhibit head/body movements and speech gestures.

The background (textured wall and paper) remains static with no shifting or fluid motion. No fire, water, smoke, or wind is visible.


A pair of white medical gloves moves across a person's face, pressing and wiping the skin in a circular motion. The person, with closed eyes and dark hair, remains still as the gloved hands adjust their position on the face. The hands stay in front of the face, with the camera maintaining a steady close-up view throughout the sequence.

Discrete solid objects: gloved hands moving to apply product to the face; recipient's face. Motion involves deliberate spreading of product with controlled hand movements.

No shifting background or fluid/environmental motion (fire, water, wind) observed. Background elements (blue cloth) are stationary and show no environmental movement.


Four children in casual clothing move from left to right across a room; the child in the purple shirt (holding a packaged item) leads, followed by a child in an orange shirt, then one in a white patterned shirt, and a child in a black shirt. The child in the orange shirt raises their right arm mid-movement while holding a small object. The camera pans right to follow their progression, with a window and shelves visible in the background.

Multiple children (solid, discrete objects) move via arm gestures, pointing, and slight body shifts while holding small items; their motion is localized and intentional.

Background elements (walls, window, cabinet) show no significant shifting or fluid motion; no fire, water, smoke, or wind effects observed.


RAW CAPTION: Okay, let's tackle this. The user wants a concise caption for the video based on the given frames. First, I need to understand the video content.

Looking at the frames: there's a purple cloth with a pentagram pattern. Multiple tarot cards are spread out. A hand is moving the cards around. The hand is handling different stacks, maybe shuffling or arranging them. The cards have various images, but I shouldn't mention specific ones since the rules say to exclude text recognition.

The main subject here is the hand moving the cards. The background is the purple cloth with the pentagram, which is part of the setting. The camera angle is top-down, as the view is looking straight down at the cards and the hand.

I need to describe the motion chronologically. The hand starts moving the cards, maybe shuffling or rearranging them. Each frame shows the hand in different positions, so the sequence is the hand interacting with the cards over time.

Focus on motion: the hand picks up, moves, and places the cards. The appearance of the hand is just a hand, probably a light-skinned one, but maybe don't specify color unless necessary. The cards are green-backed with colorful illustrations, but again, don't mention specifics beyond their general appearance.

Spatial relationships: the cards are spread on the cloth. The hand is moving them from one place to another on the cloth. The cards are in various positions—some stacked, some fanned out.

Camera perspective: top-down, no movement mentioned in the frames, so probably static. The user said "top-down" in the example output, so that's covered.

Rules to follow: exclude text, named characters, stylistic analysis. Keep it concise. Avoid background descriptions unless essential. The background here is the purple cloth with pentagram, which is part of the setting for the action, so maybe mention it briefly.

Putting it all together: Start with the scene setup (purple cloth with pentagram, cards spread), then the hand moving the cards, then conclude with camera perspective.

Check the output format: must be a paragraph inside <caption_output> tags. No extra text.

Possible draft: "A hand moves tarot cards across a purple cloth with a pentagram design, shuffling and arranging multiple green-backed decks. The hand repeatedly lifts, repositions, and stacks the cards in various orientations on the cloth. The camera maintains a static top-down view throughout the sequence."

Check rules: motion described chronologically, main subject is hand moving cards. Appearance: green-backed decks, purple cloth. Spatial: cards on cloth. Camera: top-down, static. No text or characters mentioned. Seems okay.

Wait, the rules say "briefly describe their appearance and number (color, size, orientation)". So maybe specify "multiple green-backed tarot cards" instead of decks? Also, "number" but the user says "number of people/animals/objects", but here the objects are the cards. So maybe "multiple tarot cards, each with green borders and varied imagery."

Wait, the problem says "number" but in the example output, they might just say "multiple cards" or "several cards."

Also, the cards are being handled by the hand, so the hand's action is shuffling or arranging.

Another check: "the hand picks up and rearranges stacks of tarot cards on a purple patterned cloth." Maybe "repeatedly moves and stacks the cards."

Wait, the video starts with cards already spread, then the hand is moving them. So the sequence is: the hand comes into view, moves the cards from one position to another, shuffling them.

Make sure to mention chronological order: starting with the cards spread, then the hand moving them.

Final check: concise, chronological, motion, appearance, spatial, camera.

Maybe: "A hand shuffles and rearranges multiple tarot cards with green borders on a purple cloth featuring a pentagram design. The hand repeatedly lifts and stacks the cards in different positions across the cloth. The camera remains stationary in a top-down perspective throughout."

Wait, the user said "conclude with camera perspective and movement" so need to say camera is top-down and static (no movement). The example output says "static top-down view."

Yes, so the caption should end with "static top-down perspective."

Also, check if "green borders" is correct. In the frames, the cards have green borders, so that's accurate.

Also, "varied imagery" but maybe not necessary. The rules say "appearance and number", so maybe "green-backed tarot cards with colorful illustrations."

But the rule says "briefly describe their appearance and number (color, size, orientation)". So maybe "multiple green-backed tarot cards with colorful images."

Wait, the rules say "number" but perhaps the number is implied as multiple.

Putting it all together:

"A hand manip

A hand is moving playing cards, shuffling and repositioning them across the table surface.

The background (purple tablecloth with pattern) is static and unchanging. No ambient environmental motion (fire, water, smoke, wind) is present.


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

Looking at the video provided. The first frame is a title card with text in Portuguese. But according to the rules, I need to exclude text recognition, so I shouldn't mention that. Then the next frames show a person running on a sandy field, throwing a discus. Let me check the timestamps.

Frame 0: Title card with logo and text. But rule f says exclude text recognition, so skip that.

Frames 1-5: A person in a white shirt and red shorts runs on a sandy field. Then they throw a discus. The discus is red. The person is seen from behind, then the discus is thrown. The background has buildings and trees.

Wait, the user's example output for the caption should be a paragraph. Let's outline the sequence.

First, the main subject is the person. They start running on the sand, then throw the discus. Need to describe their movement chronologically.

The person is male, wearing white shirt, red shorts, white shoes. Runs in a straight line, then throws the discus. The discus is red. The background is sandy field with buildings and trees, but background descriptions should be minimal. So maybe just mention the sandy area and distant buildings.

Camera perspective: starts with a shot of the person running, then the throw. The camera seems to follow the person's movement, maybe a static shot at first, then the throw is captured from behind.

Wait, the frames are 2-5. The first frame is title card. Then frame 1 shows the person running. The next frames: frame 2 is person running, frame 3 is still running, frame 4 is person stopping to throw, frame 5 is the discus in mid-air.

Wait, the video starts with the title card, then transitions to the person on the sand. So the caption should start from the person's action.

The rules say to focus on motion and behavior of main subjects in chronological order. So start with the person running, then throwing the discus.

Appearance: the person is wearing a white shirt, red shorts, white sneakers. The discus is red.

Spatial relationships: the person is on a sandy field. Distant buildings and trees are visible but minimal.

Camera movement: maybe a static shot initially, then maybe follows the throw. But the user says to mention camera perspective and movement. The example might have the camera staying fixed, capturing the throw.

Wait, the frames show the person running from left to right, then throwing. The camera is stationary, capturing the entire action from a side view. So the camera is static, maybe a medium shot.

So putting it all together: A person in a white shirt and red shorts runs across a sandy field, then stops to throw a red discus. The person is positioned on the sand with distant buildings visible in the background. The camera remains stationary, capturing the motion from a side angle as the discus is launched.

But need to make it concise. Let me check the example output. The user provided an example output that's a paragraph. Let me structure it:

"A person wearing a white shirt, red shorts, and white sneakers runs across a sandy field, then stops to throw a red discus. The discus is released from the person's hand, flying through the air. The background includes distant buildings and trees, but remains out of focus. The camera maintains a stationary position, capturing the entire motion from a side angle."

Wait, but the rules say to exclude text recognition and named characters, but the person's appearance (clothes) is okay as per rule b: mention appearance and number. So describing the person's clothes is acceptable.

Check the rules again: b) Briefly describe their appearance and number (color, size, orientation). So the person's outfit (white shirt, red shorts, white sneakers) is okay.

Also, check if the background is minimal. The background has buildings and trees, but since it's a sandy field, maybe just mention "distant buildings" briefly.

Now, the chronological order: run, throw, discus in air.

The video starts with the person running, then throwing. The discus is red. The camera stays static.

Wait, the frames show the person running from left to right (frame 2), then stopping (frame 3), throwing (frame 4), discus in flight (frame 5). So the motion is: run, stop, throw, discus flies.

But in the caption, need to keep it concise. So "A person in

A javelin thrower (solid object) is shown running and releasing a javelin (solid object). The javelin moves through the air after release, exhibiting projectile motion under gravity.

Background shows static elements (buildings, trees, sand field) with no significant shifting, fluid motion (fire/water/smoke), or wind-driven swaying. Minimal environmental motion observed.


A person in a white t-shirt kneels on a wooden floor, manipulating another individual's hands. The camera then pans to reveal a woman in a black sleeveless top lying face-up on a purple mat, with a man in a dark green t-shirt massaging her face. The camera shifts from a top-down perspective to a closer view of the woman as the man continues the massage.

Multiple people are moving: one lying on the mat, others interacting via physical contact (hands on face/body), exhibiting deliberate movement due to human locomotion and physical interaction.

Background elements (floor, purple mat) show minimal uniform shift; no fire, water, smoke, or wind motion detected.


A baby in a blue bouncer with orange fish and yellow sun toys moves their arms up and down, mouth open, while wearing a black and white striped outfit. The baby raises their right hand, then left hand, with slight shifts in head orientation. The camera remains close and stable, focusing on the baby against a softly blurred background.

The baby (a solid, distinct object) exhibits voluntary movements (arm gestures, facial expressions), indicating physical locomotion/force application.

Background elements (walls, furniture) show no uniform shifting or fluid motion. No fire, water, smoke, or wind-dominated phenomena observed.


RAW CAPTION: Got it, let's break this down. First, the video shows two people fencing. They're both wearing masks, so I need to note their appearance. One is in white gear, the other in a white top and green shorts. Let's track their movements chronologically.

At the start, they're facing each other. Then the person in green shorts lunges forward with their sword. The other person reacts, maybe stepping back. Then the green shorts person moves to the side, maybe after a successful move? Wait, the video has a few frames: first frame, they're in position; second, green shorts lunges; third, they're extended; fourth, maybe the other person moves; fifth, green shorts runs away. Wait, the timestamps: [0.0], [1.4], [2.5], [3.6], [4.7] seconds. Let's see the actions.

Frame 0: both facing, maybe initial stance. Frame 1.4: green shorts person (right) extends arm, maybe attacks. Frame 2.5: both are moving, green shorts is in a lunge. Frame 3.6: green shorts continues, maybe the other person is moving back. Frame 4.7: green shorts runs out of frame.

So chronological order: two fencers, one in full white gear (white top, pants, mask), the other in white top, green shorts, mask. They engage; the green shorts fencer lunges forward with sword, then the other fencer moves back. Then green shorts fencer quickly exits the frame.

Spatial relationships: initially facing, then the green shorts is to the right, lunging towards the left fencer. Then the green shorts moves right, maybe, then runs out.

Camera is stationary, maybe? The description says camera perspective: top-down? No, it's a standard indoor fencing salle, so camera is probably eye-level, maybe slight shake? The problem says "conclude with camera perspective and movement". Let's check the rules: "d) Conclude with the camera perspective and movement (e.g., top-down, pan left, slight shake)."

Looking at the video, the camera seems static, no movement. The background is a wall with photos, but we need to keep background minimal. So camera is stationary.

Now, structure the caption: first, main subjects (two fencers), their appearance, number. Then chronological actions: initial stance, green shorts lunges, other fencer reacts, green shorts moves out.

"Two fencers in fencing gear engage: one in full white attire (top, pants, mask), the other in white top and green shorts with a mask. Initially facing each other, the fencer in green shorts lunges forward with a sword, the other steps back. The green shorts fencer then moves laterally and exits the frame to the right. The camera remains stationary throughout."

Wait, check rules: b) Briefly describe appearance and number. So number: two people. Appearance: one in white gear (full), one in white top/green shorts/mask.

c) spatial relationships: initially facing, green shorts (right) lunges towards left fencer.

d) camera: stationary.

e) background minimal: yes, just mention the wall briefly? But rule e says "keep background descriptions minimal unless essential for understanding motion." The motion is fencing, so maybe the wall is not essential, but maybe the fact that it's a fencing hall. But the problem says "minimal", so maybe just say "indoor fencing arena" or just note the background as non-essential.

Wait, the example video has a wall with photos, but the caption should be concise. So maybe just say "in an indoor space with a blue wall and photos" but rule e says minimal, so maybe omit.

Let's try:

"Two fencers, one in full white gear and one in white top with green shorts, face each other in an indoor setting. The fencer in green shorts lunges forward, extending a sword toward their opponent, who steps back. The green shorts fencer then moves laterally to the right and exits the frame. The camera remains stationary."

Check if all rules are met:

a) motion and behavior chronological: yes.

b) appearance: two people, one full white, one white/green.

c) spatial: facing, green shorts lunges toward opponent (opponent steps back), then green shorts exits right.

d) camera: stationary.

e) background minimal: just "indoor setting" is okay.

f) exclude text, names: yes.

g) don't output reasoning.

Now, make it concise. Let's see the example format.

Also, the first frame: they are in position. Second: green shorts lunges. Third: extended. Fourth: moving back. Fifth: runs out.

So "

Two fencers (people) moving in a fencing bout, exhibiting discrete locomotion and attacks.

No shifting background elements; no fire, water, smoke, or wind present.


RAW CAPTION: Got it, let's break down the video. First, the scene: a woman and a black dog. The woman is wearing a light-colored top and shorts, maybe an orange top? She's handling a red leash or something. The dog is black, wet, standing on a paved area. The background has green trees.

Looking at the timestamps:

0.0s: Woman is holding a red hoop or hula hoop, maybe, standing with the dog. The dog is in front of her.

1.4s: She's bending down, adjusting the dog's position. The dog is on the ground, maybe? Wait, no, the dog is standing. Wait, the dog is standing on the pavement. She's moving the hoop, then maybe placing something?

Wait, the video shows her handling the dog, which is wet, so maybe they were in water. She's adjusting the leash or the dog's position.

In chronological order:

- Start: Woman is standing with the dog, holding a red object (maybe a hula hoop or a leash). The dog is black, standing on a wet pavement.

- Then, she bends down, adjusts the dog's position, possibly securing it. The dog remains standing.

- She continues to handle the dog, maybe petting or adjusting. The dog is still standing, facing left or right?

Background: Green trees, paved area with some puddles.

Camera: Maybe a slight move? The video seems to be from a car window? Wait, the caption should mention camera perspective.

Wait, the output format says: "Conclude with the camera perspective and movement (e.g., top-down, pan left, slight shake)."

Looking at the frames: the first frame shows the woman and dog, then the camera might be panning or slightly moving. But need to check.

The video starts with the woman holding a red hoop, then she bends down, adjusts the dog. The dog is black, wet, standing on pavement. The woman is wearing a light top and dark shorts.

Chronological paragraph:

At the beginning, a woman in a light-colored top and dark shorts stands on a paved area with a black dog, holding a red circular object. She bends down to adjust the dog's position, which remains standing on the wet pavement. She continues to handle the dog, possibly securing it with the red object, as the dog stands still. The background features dense green trees. The camera maintains a slight movement, capturing the scene from a ground-level perspective.

Wait, need to follow the rules: concise, chronological, mention motion, appearance, spatial relationships, conclude with camera.

Let me structure it:

A woman in a light top and dark shorts interacts with a wet black dog on a paved surface. She bends down to adjust the dog's stance while holding a red hoop, then stands to continue handling the dog. The dog remains stationary, facing left, with green foliage in the background. The camera captures the scene with slight movement from a ground-level perspective.

Wait, but need to check the exact sequence. Let's go frame by frame:

Frame 0: Woman stands, holding a red hoop, black dog beside her.

Frame 1: She is bending over, the hoop is on the ground, dog is next to her.

Frame 2: She is adjusting the dog, placing the hoop near the dog's legs.

Frame 3: She continues to adjust, the dog is standing.

So the motion is: woman starts standing with hoop, bends down, adjusts the dog (maybe the hoop is around the dog's legs?), then continues to adjust.

Appearance: woman in light top (maybe sleeveless) and shorts, black dog, wet.

Spatial: dog in front of her, then she bends down, so she's behind the dog? Wait, the dog is standing, she's bending over to handle it.

So:

A woman in a light-colored sleeveless top and dark shorts bends down to adjust a wet black dog standing on a paved surface, while handling a red hoop. She positions the hoop around the dog's legs and continues to adjust the dog's stance, which remains still. The background features dense green trees. The camera maintains a steady perspective with slight movement, capturing the action from a ground-level view.

Wait, but need to be concise. Let's check the rules again.

Focus on motion and behavior of main subjects in chronological order.

Main subjects: woman, black dog.

Motion: woman starts standing, holds red hoop, then bends down, adjusts dog, handles the hoop near the dog's legs, continues adjusting.

Appearance: woman—light top, dark shorts; dog—black, wet.

Spatial: dog is on pavement, woman is behind/next to dog when bending.

Background: minimal, green trees.

Camera: steady or slight movement?

The video frames show the camera moving

A person (wearing a red top and white vest) and a black dog are moving together, with the dog walking on a leash held by the person; both exhibit locomotive motion consistent with walking.

The background consists of stationary trees and a concrete surface with no shifting or fluid motion; no fire, water, smoke, or wind is visible as dominant elements.


A person in a blue shirt sits at a drum set, their hands moving rhythmically to strike the drumheads. The individual's head is slightly bowed, with cymbals visible to the sides of the kit. The camera remains stationary with a slight shake throughout, capturing the continuous drumming motion.

A person (drummer) in blue shirt is moving their arms and hands to hit the drums and cymbals. The drumsticks and the drum heads are also moving (vibrating) due to the impact.

No shifting background or fluid motion observed. Environment is static indoors.


A person wearing a patterned light shirt adjusts a stack of white papers on a wooden table, moving the papers with hands and placing an orange pencil on the stack. The camera maintains a close-up perspective with slight movement, focusing on the table and actions.

Discrete solid objects (person's hands, stack of white papers, and orange pencil) are actively moving through manual manipulation (flipping, lifting, and adjusting the papers).

No shifting backgrounds or fluid/environmental motion observed; wooden table and chair remain static throughout the clip.


RAW CAPTION: Okay, let me tackle this video captioning task. The user wants a concise, chronological paragraph focusing on the main subjects' motions and behaviors.

First, looking at the video frames. There are two people: one in a blue shirt and another in purple. Both are wearing headbands with the "LASERFIELD" logo. They're holding black laser tag guns.

Starting from frame 0, they're facing each other. The person in blue is on the left, holding a gun. The person in purple is on the right, aiming her gun at the blue-shirted person. Then in frame 1, the purple-shirted person moves her gun down, maybe lowering it. Frame 2 shows the blue-shirted person lifting their gun up. Frame 3, the purple-shirted person moves out of frame to the right. Then frame 4, the blue-shirted person is still there but now looking to the side. Frame 5, they're both back, but the purple-shirted person is now on the right. Wait, frame 5 says both are facing the camera, but their positions might have changed.

I need to describe the sequence in order. The key motions: they start facing each other, then the purple-shirted person lowers her gun (maybe a miss), blue-shirted person raises theirs. Then purple moves out of frame, then reappears on the right. But maybe the main points are the actions like aiming, shooting, moving positions.

Wait, the user's example says in the output to keep it chronological. So first, two people face each other. Then the blue-shirted person raises his gun, purple lowers hers. Then purple moves right and exits frame. Then blue-shirted person is alone, then both reappear. Wait, but looking at the frames: frame 0 has both facing each other. Frame 1: purple lowers her gun (maybe after shooting), blue raises his. Frame 2: purple is moving out of frame to the right. Frame 3: purple is gone, blue is looking right. Frame 4: purple is back in the frame, moving left. Frame 5: both are in frame again, facing the camera.

Wait, maybe the exact sequence is:

- Frame 0: Both facing each other, holding guns.

- Frame 1: Purple lowers her gun (maybe after firing), blue raises his.

- Frame 2: Purple moves out of frame to the right.

- Frame 3: Blue is looking right, purple is gone.

- Frame 4: Purple re-enters frame from the right, blue is still there.

- Frame 5: Both are in frame, facing each other again.

But the user's instruction is to be concise. Need to condense into a paragraph. Mention the two people: blue shirt, purple shirt, headbands. Actions: they aim at each other, then the purple person lowers her gun, moves out of frame, then returns. The camera is static, maybe a slight pan?

Wait, the problem says "conclude with camera perspective and movement." The background is plain white, so minimal description. The camera seems static, no movement mentioned, but maybe a slight pan as they move.

Wait, the original video's camera might be stationary. The rules say exclude text recognition, so no need to mention the logo. Focus on motions.

Let me structure it:

Two individuals face each other, each holding a black laser tag gun. The person in blue shirt raises their gun, while the person in purple shirt lowers theirs and moves right, exiting the frame. The blue-shirted individual then turns right, followed by the purple-shirted person re-entering from the right, both regaining position facing the camera. The camera remains static throughout.

Wait, check the frames again. Frame 0: both facing each other. Frame 1: purple lowers gun, blue raises. Frame 2: purple moves right out of frame. Frame 3: blue is looking right (purple gone). Frame 4: purple comes back from right, blue still there. Frame 5: both face camera again.

So the chronological order:

Start with both facing, then purple lowers gun, moves out of frame, blue turns, purple re-enters, then they face each other again.

Need to keep it concise. Maybe: Two people face each other, each holding black laser tag guns. The person in the purple shirt lowers their gun and moves right, exiting the frame. The person in the blue shirt raises their gun, then turns right. The purple-shirted person re-enters from the right, and both face the camera again. The camera remains static.
</think>

<caption_output>Two individuals face each other, each holding a black laser tag gun. The person in the purple shirt lowers their gun and moves right, exiting the frame. The person in the blue shirt raises

Two people (solid, distinct objects) move their heads, bodies, and toy guns via locomotion and physical actions.

Background is a static white wall with no shifting or environmental motion (fire, water, smoke, wind).


Two individuals sit on a stone ledge partially submerged in a river, with a stone bridge in the background. The person on the left wears a light gray top and dark pants, while the person on the right wears a dark top and blue jeans. They face each other, repeatedly extending their hands to grasp one another’s hands, then pulling apart and repositioning. The camera maintains a steady perspective with slight movement, capturing their interaction from a fixed angle.

Two people: one standing on the ledge with feet in water (kicking/splashing), the other seated holding the standing person's hand/arm. Motion is due to their physical interaction and locomotion.

The bridge and stone ledge background remains static throughout; water is calm with minimal splashing caused by the people's feet, not dominant motion.


RAW CAPTION: Got it, let's tackle this caption. First, the video shows a person sliding down a snowy ramp. The main subject is a man in dark clothing with a yellow sled. He starts at the top, slides down. Then there's a switch to another person standing near a railing, but wait, the main action is the sliding. Let's check the timestamps.

First part: The man is at the top of the ramp, then slides down. The video shows him sliding, so chronological order: starts at the top, moves down the ramp. Appearance: dark jacket, yellow sled. Spatial: sliding down the ramp. Background: snowy area, some buildings and trees. Then the camera shifts to another scene with two people near a railing, but the main focus is the sliding. Wait, the video has two clips: first the sliding, then a cut to two people standing. Wait, the user's description is the video as given: first clip is the slide, then the next frame (maybe) shows two people. Wait, looking at the frames: [0.0] to [4.7] is the sliding, then [4.8] is the switch. So the main motion is the person sliding down the snow ramp. Then the camera shows two people standing by a railing. Wait, no, the user's video description says: the video starts with a person at the top, slides down, then transitions to two people standing. So we need to describe the chronological order.

So first, a person in dark clothing on a yellow sled begins sliding down a snow-covered ramp, moving from the top towards the bottom. Then the scene shifts to two individuals standing near a railing, one in a dark coat and the other in a gray coat. Wait, but the task is to focus on the main subjects' motion. The first part is the sliding, which is the main action. The second part is a brief cut. But the rules say "chronological paragraph", so we need to mention the sequence.

Let me structure it:

1. The video starts with a person in dark clothing and yellow sled at the top of a snow ramp.
2. They slide down the ramp, moving forward.
3. Then the scene transitions to two people standing near a railing (but maybe that's a different scene, but the task is to capture the main motion first).

Wait, the user's input has the video split into two parts: the first part is the sliding (frames 0 to ~5), then frame 5.8 is the two people. So the caption should cover the main motion first, then the next part.

But the rules say: focus on motion and behavior of main subjects in chronological order. So the main subject is the person sliding. Then the next scene is two people standing. So:

A person wearing dark clothing and a yellow sled slides down a snow-covered ramp, moving from the top toward the bottom. The scene then shifts to two individuals standing near a railing, one in a dark coat and the other in a gray coat.

Wait, but the rules say minimal background. Also, the camera movement: for the sliding part, the camera follows the person, maybe panning or moving with the slide. Then for the second scene, it's a static shot? The video description says "the camera perspective and movement".

Let's check the video:

First part: the person is sliding down, so the camera is likely tracking the movement, maybe following the slide. So "the camera follows the person as they slide".

Second part: the scene changes to two people standing, so the camera is stationary here.

So putting it together:

A person in dark clothing on a yellow sled begins sliding down a snow-covered ramp, moving forward with increasing speed. The camera follows their descent, capturing the motion down the slope. The scene then transitions to two individuals standing near a railing, one in a dark coat and the other in a gray coat.

Wait, but we need to be concise. Let's check the rules: "concise, chronological paragraph". So:

A person in dark clothing, seated on a yellow sled, slides down a snow-covered ramp, moving from the top toward the bottom. The camera follows their descent. The scene then cuts to two individuals standing near a railing.

But need to be precise. Let's make sure to include the key elements:

- Main subject: person (dark clothing, yellow sled) sliding down the ramp.
- Chronological: starts at top, slides down.
- Then the scene changes to two people standing.

Also, mention spatial relationships: the ramp is enclosed by white barriers. Background: trees and buildings, but minimal.

So revised:

A person wearing dark clothing and a yellow sled slides down a snow-covered ramp enclosed by white barriers, moving from the top toward the bottom. The camera tracks their descent along the slope. The scene then shifts to two individuals standing near a railing

A person on a sled slides down a snow-covered track; the motion is continuous and distinct, involving controlled locomotion due to gravity and sled dynamics.

The snow-covered walls and trees remain static throughout the video; no significant fluid motion (fire, water, smoke) or wind-driven movement is observed, with ambient conditions remaining calm.


RAW CAPTION: Got it, let's tackle this video caption. First, I need to follow the rules. Let's break down each frame.

The video starts with three kids sitting on the floor. One in white shirt, one in red, and another in front maybe? Wait, first frame: a girl in dark top with long hair, maybe wearing a white shirt? Wait, the first frame shows kids on carpet. Let's check the sequence.

Frame 0: Kids sitting on floor, carpet. A girl in white shirt (front left), another in dark top (behind?), red shirt kid on right with a gift. There's a colorful mat or something with small toys.

Frame 1: Same scene, but the kid in front (dark top?) moves their hand up. The girl in white is still there, red shirt kid is there. The gift box is visible.

Frame 2: The camera moves up, showing more of the room. The kids are still sitting, but the background has a wall with a plant. The girl in white is to the left, red shirt kid to the right, another kid in black behind? Wait, no, the kids are three: one in white, one in red, and another in black? Wait, frame 0-3: the main subjects are three kids. Let's count.

Frame 0: three kids? Wait, first frame has a girl (front) with long dark hair, wearing dark top, white shirt kid behind her, red shirt kid on right. So three kids.

Frame 1: same three, but maybe the white shirt kid is moving. The red shirt kid has a gift, maybe a present.

Frame 2: camera pans up, showing the room better. The kids are sitting on the floor. There's a gift box (red with white polka dots) next to the red shirt kid. A person in black is sitting behind the kids?

Frame 3: now the camera is higher, showing the room. The kids are in a group: one in white shirt (left), one in black (middle), one in red (right). The black-shirted kid has a gift box. The red shirt kid has a big gift. The white shirt kid is in front.

Frame 4: The camera continues to move, showing the room's background: a door, a plant on the wall, a chair. The kids are still sitting.

Frame 5: The camera is now focused on the kids, showing their faces. The white shirt kid is looking at the red shirt kid, who is holding a gift. The black shirted person is behind.

Now, chronological order. The video starts with kids sitting on the floor. The camera moves from a low angle to a higher angle, panning up. The main subjects are three children: one in white shirt (long hair), one in black shirt, one in red shirt with a gift. They are sitting on the carpet, with a gift box (red with white dots) and another gift. The camera starts close, then moves up, showing the room. The kids' actions: maybe the white shirt kid moves their hands (frame 1), but overall, they are sitting together, looking at the gifts.

Need to focus on motion and behavior. The camera is moving upward, panning left? Or from low to higher. The sequence: starts with close-up of kids on floor, camera moves up to show the room, revealing more of the setting. The kids are sitting in a group, holding gifts, interacting.

Appearance: three children, white shirt (long hair), black shirt, red shirt (with a gift). Spatial: red shirt kid is to the right of the black shirted person, white shirt kid to the left.

Background: minimal, but there's a door, plant, chair visible as camera pans up.

Now, the caption should be concise, chronological. Start with the initial scene, then camera movement.

Let me draft:

Three children sit on the carpet: a girl in a white shirt with long hair, a boy in a red shirt holding a gift, and a person in a black shirt. The camera starts low, capturing their seated position with a colorful mat and small toys nearby, then pans upward to reveal a wall with a plant and a chair in the background, while the children remain seated, focusing on the gifts.

Wait, but need to check the number. Let's see:

Frame 0: three kids? Yes, white, red, and another. Frame 1: same. Frame 2: three. Frame 3: three. Frame 4: three. Frame 5: three.

So three main subjects.

Check the rules:

a) Motion and behavior: camera moves up, kids are seated.

b) Appearance: white shirt (long hair, girl?), red shirt (boy), black shirt (person). But the rules say

Children and an adult are seated, with one child raising a hand and others interacting with a gift box.

No shifting background elements observed. No fluid or environmental motion (fire, water, smoke) detected.


A baby with light hair, wearing a striped shirt and a stained white bib, sits in a high chair with a blue patterned cushion. The baby raises their right hand, then moves their left hand, and an adult's hand enters the frame holding a spoon with food, offering it to the baby. The camera remains static, focused on the baby from a frontal perspective.

The baby (discrete solid object) is moving its arms and hands, with clear voluntary motion such as raising and lowering limbs. No other objects exhibit significant motion.

No significant shifting backgrounds or environmental fluid motion observed. Static elements like the blue high chair fabric and background wall remain stable throughout the frames.


A person wearing a black jacket and white shirt folds stacked clothing and places them into an open brown suitcase containing a yellow shirt, then closes the suitcase. The scene occurs in a retail setting with a glass table holding folded towels and a black case. The camera follows the action with a slight shake.

Discrete solid objects: person's hands (moving to pack items) and suitcase contents (clothes, folded items) exhibit explicit physical motion due to intentional packing actions.

Background elements (table, floor, static objects) show no uniform shifting or fluid motion (fire, water, smoke, wind). No ambient environmental forces are present.


A female athlete in a white tank top and blue shoes sprints toward a sandpit on a grassy field, kicking up dust. The scene shifts to another female athlete in a black and white athletic outfit running on a red track, approaching a high jump bar; she leaps over the bar and lands on a red mat, with officials and other athletes visible in the background. The camera follows the second athlete’s jump from a side angle, capturing her motion as she clears the bar and settles on the mat.

Athletes (e.g., the girl running/jumping in sand pit, the high jumper) are moving via locomotion and physical force (e.g., jumping, landing).

Background elements (bleachers, spectators, buildings) are static with no shifting or fluid motion (e.g., no fire, water, wind).


A person in a brown shirt crouches on a concrete surface, working with a row of metal pans on a wooden structure, each holding a green object. A second individual in dark pants approaches, using a tool to adjust the pans while another person in a blue shirt stands nearby. The camera pans right, capturing the sequential handling of the pans and the workers' coordinated motions, with slight movement and shake. The scene centers on the interaction between the workers and the metal pans, with minimal background detail.

A person (discrete object) is moving their hands to strike gongs, with motion concentrated on their upper body and limbs.

No significant ambient environmental motion (fire, water, smoke, wind) observed. Background elements (ground, structures) appear stable without uniform shifting.


A person wearing blue shorts and green rubber boots uses a spade with a black handle to dig into a garden bed next to a brick pathway. They lift the spade, insert it into the soil, and push downward repeatedly to create a trench along the edge of the pathway. The camera remains stationary, capturing the action from a side angle with minimal background details.

A person (wearing blue shorts and black boots) is using a shovel to dig into the mulch on the ground.

No shifting background elements observed. No fire, water, smoke, or wind motion dominating the scene.


RAW CAPTION: Okay, let's tackle this video caption request. First, I need to understand the user's requirements. They want a concise chronological paragraph 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. The main subject here is the person and the doll. So I need to describe what happens step by step.

Rule b) Briefly describe appearance and number. The person is wearing a green top and jeans, holding a blonde doll with a floral dress. The doll is the main object.

Rule c) Mention spatial relationships if relevant. The person is sitting on a bed, maybe? The background has a bunk bed, dresser, etc., but the user says to keep background minimal unless essential. So maybe just note that the person is in a room with a bed and dresser.

Rule d) Conclude with camera perspective and movement. The video seems to be a static shot from a fixed camera angle, maybe slightly shaky? The original frames show the camera is fixed but might have slight movements.

Rule e) Keep background minimal. So mention the bed and dresser briefly, but not too much.

Rule f) Exclude text, names, stylistic analysis. So no mention of specific brands or text on objects.

Looking at the video frames: the person is sitting, holding the doll. They bring the doll close to the camera, then move it around. The doll is a blonde doll with a floral dress. The person is wearing a green top and jeans.

Chronological order: The person holds the doll, moves it up towards the camera, then brings it down. Then maybe adjusts their position.

Let me outline the steps:

1. Person sits on bed, holding doll.
2. Lifts doll towards camera, showing it closely.
3. Moves doll slightly left, then back down.
4. Camera is fixed, maybe slight shake.

Wait, the user says to describe motion in chronological order. Let's see the timestamps. From 0 to 5 seconds:

0.0 - Person holds doll in front.

0.3 - Person moves doll towards camera.

1.4 - Doll is closer, person adjusts.

2.5 - Doll is up close, maybe face is visible.

3.6 - Person moves doll away.

4.7 - Doll is back in hand, maybe sitting down.

So the sequence is: person holds doll, brings it close to the camera (maybe tilting up), then pulls it back down, and then maybe adjusts position.

Appearance: Person has long hair, green top, jeans. Doll has blonde hair, blue floral dress.

Spatial: The person is on a bed; the background includes a bunk bed frame and a dresser with clothes.

Camera perspective: It's a static shot, but the person's movements cause slight motion. Maybe the camera is slightly shaky, as per the description.

Putting it all together:

A person in a green top and jeans sits on a bed, holding a blonde-haired doll wearing a blue floral dress. They lift the doll upward toward the camera, bringing it close to the frame, then lower it slightly while adjusting their grip. The doll’s face and dress are visible as they move it. The scene takes place in a room with a bunk bed and dresser in the background. The camera remains stationary with minimal movement, capturing the action from a frontal perspective.

Wait, need to check the rules again. Rule d: Conclude with camera perspective and movement. So after describing the action, mention camera.

Also, rule e: minimal background. So maybe just mention the bed and dresser as background elements.

Let me adjust:

A person wearing a green top and jeans sits on a bed, holding a blonde doll dressed in a blue floral outfit. They move the doll upward toward the camera, bringing it close for a clear view, then lower it slightly while shifting their grip. The background includes a bunk bed frame and a dresser. The camera remains static with minimal shake, capturing the scene from a frontal viewpoint.

Wait, but the user says "conclude with camera perspective and movement". So the last part should be about camera.

Also, check if the description is chronological. The sequence of actions is lifting up, then lowering. Then maybe adjusting.

Another thing: the doll is lifted, then held close (maybe the person brings it closer to their face?), then lowers it again.

Looking at the frames: in frame 2, the doll is very close to the camera, face visible. Then in frame 4, the person moves the doll down.

So the motion is: hold doll, lift to camera, close up, then move down.

So the caption should be:

A person in a green top and jeans sits on a bed, holding a blonde doll in a blue floral dress. They lift the doll toward the camera, bringing it close to the frame, then lower

The person manipulates a doll through controlled motions: lifting it vertically, bringing it close to their face, and adjusting its position. The doll is a discrete solid object being moved by the person's hands, with clear physical interactions (e.g., lifting, holding).

The background includes a fireplace with visible flames and smoke, which is an ambient environmental element. However, the fire's motion is not dominant in the video; it appears as a minor background feature without significant fluid dynamics. Static elements like the fireplace structure and furniture remain fixed, showing no uniform shift.


A person wearing a white patterned dress shirt adjusts a maroon tie with gold patterns. Initially, both hands pull the tie upward toward the neck, then one hand smooths the tie against the collar while the other guides its position. The person’s hands continue to refine the tie’s alignment, ensuring it sits neatly against the shirt. The background is a solid yellow wall. The camera maintains a close-up, static shot focused on the upper torso and neck area throughout.

The person's hands are moving to adjust and tie a red necktie. The tie itself moves as the hands manipulate it.

The background is a static yellow wall with no signs of fluid motion, fire, water, or wind. There is no dominant ambient environmental motion.


Two men stand facing each other on a sidewalk; the man in the black shirt gestures with his right hand toward a nearby building, then both men walk side by side along the sidewalk as the man in black continues gesturing. The camera remains steady, maintaining a ground-level perspective.

Two men (discrete solid objects) move: the right man gestures with his arm and walks away, the left man turns his head and then walks away. Their motion is tracked via bounding box.

No shifting background elements (trees, building, parked car remain stationary). No fluid/environmental motion (e.g., wind, smoke, fire) observed; trees are motionless.


The video opens with a dark central space surrounded by stationary crowds. A single figure in white enters the dark area from the left, followed by two more, forming a group of three. The three figures move in synchronized motion across the dark space, shifting positions and occasionally converging. The crowd remains on the periphery, while the camera maintains a fixed top-down perspective.

Discrete solid objects (people) are moving in the spotlight area, performing choreographed dance movements (locomotion).

The background crowd is stationary; no fire, water, smoke, or wind observed. Background elements (walls, ground) are fixed, indicating no ambient environmental motion.


A hand holding a red paintbrush moves across a colorful canvas featuring yellow, green, purple, and orange paint. The hand enters from the left, strokes the canvas horizontally, then withdraws. The camera maintains a top-down perspective throughout.

A hand holding a paintbrush is moving across the canvas, applying yellow paint to a pre-existing green and orange artwork. The hand and brush are solid, distinct objects exhibiting motion due to deliberate physical action.

The wooden surface background shows no significant shifting or environmental fluid motion (e.g., fire, water, smoke). Background elements remain stable.


RAW CAPTION: Got it, let's see. The video shows someone pouring something from a white bowl into a glass bowl with food, then adding more ingredients. First, the person's hands are pouring white, diced items (maybe cheese or onions) from a white bowl into a glass bowl. Then, they use a spoon to add a liquid (maybe oil or sauce) from a small container. The table has a floral tablecloth, some stacked bowls, a bear figurine. But I need to focus on the motion. Let's break it down:

- Start: Hands pour white diced food from white bowl into glass bowl (which has other ingredients, maybe nuts or something).
- Then, hands use spoon to add liquid from small container into the glass bowl.
- The background has a floral tablecloth, stacked white bowls, a teddy bear, but minimal for motion.

Rules: Chronological order, motion of main subjects (hands), appearance (white bowl, glass bowl, hands), spatial relationships (tablecloth under, stacked bowls left), camera perspective (top-down, no movement).

So the caption should be: A person's hands pour white diced food from a white bowl into a glass bowl containing mixed ingredients on a floral tablecloth. Then, the hands use a spoon to add a liquid from a small container into the bowl. The scene includes stacked white bowls and a teddy bear figurine to the left. The camera maintains a top-down perspective throughout.

Wait, check the rules. Keep background minimal unless essential. The teddy bear might be essential? Maybe not. Focus on main motion. Let's make it concise.

"Hands pour white diced food from a white bowl into a glass bowl with mixed ingredients on a floral tablecloth, then add liquid from a small container using a spoon. Stacked white bowls and a teddy bear figurine are visible to the left. The camera remains top-down with no movement."

Check if that's chronological. First pouring, then adding liquid. Correct. Mention the motion. Appearance: white bowl, glass bowl, hands (color? black shirt maybe, but rule says mention color if relevant. The hands are in a black shirt, but maybe just "person's hands" without color unless necessary. The problem says "briefly describe their appearance and number (color, size, orientation)". So hands are visible, but maybe no need for color. Focus on action.

Wait, the first frame: hands pouring, then second frame shows pouring, then hands adding liquid. So the sequence is pouring then adding liquid.

Let me structure it:

A person's hands pour white diced food from a white bowl into a glass bowl containing mixed ingredients. The hands then use a spoon to add liquid from a small container into the bowl, all on a floral tablecloth. Stacked white bowls and a teddy bear figurine are positioned to the left of the scene. The camera maintains a static top-down view.

Check if background is minimal. The teddy bear and stacked bowls are background, but maybe essential? The problem says "keep background descriptions minimal unless essential for understanding motion". Since the motion is about the bowl and ingredients, maybe the stacked bowls aren't essential. But the teddy bear is in the background. Hmm, maybe just mention the tablecloth and the other items briefly.

Wait, the example in the rules: "if relevant". The tablecloth is part of the setting, so it's relevant. The stacked bowls and teddy bear are in the background. Maybe "to the left" is relevant.

But let's keep it concise. Let's see:

Hands pour white diced food from a white bowl into a glass bowl on a floral tablecloth. Next, the hands use a spoon to add liquid from a small container into the bowl. Stacked white bowls are visible to the left of the scene. The camera remains top-down throughout.

Yes, that's better. Remove the "teddy bear" because maybe it's not essential for understanding the motion. The problem says "keep background descriptions minimal unless essential". The motion is about pouring and adding, so the stacked bowls might be background but not essential. So maybe omit the teddy bear. The video shows a teddy bear, but if it's not needed, remove.

Wait, the first frame has a teddy bear, but maybe not necessary. Let's check the video description:

"<0.3 seconds> ... [teddy bear], stacked white bowls, etc."

But the rules say minimal background. So maybe just the tablecloth and the other relevant objects. So:

A person's hands pour white diced food from a white bowl into a glass bowl containing mixed ingredients on a floral tablecloth. The hands then use a spoon to add liquid from a small container into the bowl. Stacked white bowls are positioned to the left. The camera maintains a top-down perspective with no movement.

Wait, "mixed ingredients" in the glass bowl. The video

A person's hands pour a white substance from a cup into a bowl, then stir the contents; both hands and the bowl are discrete solid objects undergoing physical interaction.

Static background elements (floral tablecloth, small bear figurine, white cups) show no uniform shifting or fluid motion (fire, water, smoke, wind).


A person with dark-sleeved hands manipulates a white applicator near the gray-furred side of an animal, positioning it against the fur, pressing the device, and adjusting its angle. The background consists of a light brown textured surface. The camera maintains a close-up top-down view throughout the sequence.

Hands (discrete, solid object) are actively moving to apply a substance (e.g., liquid or paste) to an animal's fur. The animal's fur is the secondary object, but the primary motion comes from the hands' deliberate actions.

The background consists of a static surface (likely ground) with no significant shifting or environmental elements like fire, water, or wind. No fluid or gaseous motion is present.


A single person in dark pants and light top walks and swings their arms across a brightly lit stage. As they move, the background transitions from dark to reveal a seated audience behind them. The camera remains fixed, capturing the subject's motion from a frontal angle.

A single human dancer moves dynamically across the stage, performing locomotion and expressive gestures.

The background consists of dark walls and structures with no shifting or fluid motion; no fire, water, smoke, or wind is present.


The video begins with a black screen, then transitions to a well-lit room where a man in a dark blue shirt and gray pants stands and gestures while speaking, and a woman in a white top and black pants sits on a blue exercise ball. A table covered with a blue cloth and framed pictures hang on the wall behind them. The camera remains static throughout.

Two people are visible: one standing and one seated on a blue exercise ball, with the seated individual moving the ball and interacting with the standing person.

Background elements (walls, framed pictures, door, tablecloth) remain static with no shifting or environmental fluid motion (fire, water, smoke, wind).


A person in dark blue athletic wear stands within a netted batting cage on green flooring, raising a bat in preparation, then executing a forward swing motion, followed by stepping forward and lowering the bat after the swing. The camera maintains a stationary position, capturing the sequence from a fixed perspective.

A person is performing distinct physical actions: swinging a bat-like object and walking. The motion is driven by human locomotion and intentional movement.

The background consists of static green screen elements and structural features with no shifting or fluid motion (fire, water, smoke, wind).


A person in a dark blue shirt and dark shorts sits cross-legged on a gray mat, interacting with a green board game in front of them. The individual looks up toward the camera, gestures with both hands, then points to the game. To the left, a gray pet bed with a blanket rests on the wooden floor. The camera begins with a top-down view, tilts upward to focus on the person's face, and then shifts slightly.

The child is the only moving discrete object, exhibiting hand movements (holding/dropping an object, spreading arms), slight body shifts, and head turns. These motions are localized and self-propelled.

Background elements (wooden floor, gray mat, blue plate, and shelf items) remain stationary throughout. No fluid motion (fire, water, smoke, or wind) is present.


RAW CAPTION: Got it, let's break this down. The video shows a person in a netted area, probably a sports field. First, the person is standing, then starts spinning around. They're wearing a dark shirt, blue shorts, and blue shoes. The motion is rotational, like in shot put or hammer throw. The net is around them, so it's a throwing cage. Then, the person releases the object (maybe a shot put or hammer) and it's not visible in the frame after. The background has trees and a clear sky. The camera is static initially, then maybe the action causes a shake. Need to follow the rules: chronological order, focus on motion, describe appearance briefly, spatial relationships (like in the netted cage), camera movement. Let's structure it.

Start with the person's initial position: standing in a netted area, wearing dark shirt, blue shorts, blue shoes. Then they begin spinning, rotating clockwise (since in the frames, the motion is circular). As they spin, they generate momentum. Then, after spinning, they release the object (probably the shot put), and the object leaves the frame. The camera is inside the net, maybe fixed, but the action might cause a slight shake or the frame shifts (the last part shows the sky with clouds, maybe the camera moved or the object's trajectory). But need to be concise.

Check rules: don't mention background details unless essential. The net is part of the area, so mention it. The main subject is one person. Motion: starts stationary, spins, releases. Camera: the video has a static camera that might capture the action, but in the last frame, maybe a shift. Wait, the video goes from the person spinning, then at the end, the view shifts to the sky with clouds. So the camera might have panned up or the action caused the camera to move.

Wait, the rules say "Conclude with the camera perspective and movement". So need to say what the camera does. Let's outline:

- A person wearing a dark shirt, blue shorts, and blue shoes stands in a netted throwing area. They begin rotating in a circular motion, building momentum as they spin. After completing the rotation, they release the object, which exits the frame. The camera remains static within the netting but shifts focus to the sky with clouds during the release.

But need to check chronological order. First, the person is standing, then spins, then releases. The video ends with the sky (maybe the camera moved). Also, spatial: the person is in the center of the net. The net is enclosing them, so "inside a netted enclosure".

Let me rephrase concisely:

A person in a dark shirt, blue shorts, and blue shoes stands inside a netted throwing cage, rotating clockwise to build momentum. They release the object, causing the camera to capture a brief view of the sky before returning to the scene. The camera remains stationary but exhibits a slight shake during the release.

Wait, but the last frame is split screen? The video shows at the end a split screen with the sky on the left and the cage on the right. So maybe the camera moves or shifts. But the task is to describe the video chronologically. Let's see the timestamps:

[0.0] person standing, [1.4] starts spinning, [2.5] mid-spin, [3.6] spinning faster, then [4.7] split screen (sky on left, cage on right). So the last frame shows the sky, meaning the camera might have panned up or the action caused the view to shift.

So the caption should mention the split screen at the end. But the rules say "conclude with camera perspective and movement". So:

A person wearing a dark shirt, blue shorts, and blue shoes rotates in a circular motion inside a netted throwing cage, building momentum before releasing the object. The camera remains fixed but shifts focus to the sky with clouds during the release, capturing a split-screen view of the sky and cage.

But need to be concise. Let's check:

- Main subject: one person, clothing described briefly.
- Motion: starts stationary, spins, releases.
- Spatial: inside netted cage, rotating.
- Camera: static initially, then shifts to sky at end.

Wait, the rules say "briefly describe their appearance and number". So "a person wearing a dark sleeveless shirt, blue shorts, and blue shoes" but maybe "dark shirt, blue shorts, blue shoes" is enough.

Let me draft:

A person in a dark shirt, blue shorts, and blue shoes stands inside a netted throwing area. They begin rotating in a clockwise direction, building momentum through several spins. After releasing the object, the camera shifts to show a split-screen view of the sky with clouds on the left and the cage on the right.

A person (wearing a blue shirt and dark shorts) is running and performing a throwing motion (likely discus or hammer throw) in an outdoor field.

The background (net, trees, power lines) is static. There is a brief sky scene (clouds) which is ambient environmental, but it is not dominant as the majority of the video (3.5 seconds) shows a person moving in the field.


A person in dark clothing sits at a table with yellowish documents and other papers spread out. They move their hands, gesturing toward the table and adjusting items. The person remains seated throughout, with their hands actively shifting position over the table surface. The camera maintains a static perspective focused on the table and the person’s upper body, capturing the motion without shifting angle or movement.

A person (human) is moving, making hand gestures and head movements.

The background elements (desk, wall) are static and do not shift uniformly. No fluid, fire, water, or smoke motion is present.


A man in a white tank top, red shorts, and black shoes stands in a circular throwing area, initiating a counterclockwise spinning motion to build momentum. He rotates fully within the circle, maintaining balance while preparing for the throw. The camera remains stationary, positioned behind a chain-link fence, capturing the athlete’s movement against a grassy field with faint figures in red in the background.

A person in red shorts and a gray shirt is performing a throwing motion (likely shot put), moving through distinct locomotion and rotational actions. The motion is explicitly physical (body movement, arm extension) and easily trackable with a bounding box.

The chain-link fence and grassy field in the background show no uniform shifting or fluid motion (e.g., no fire, water, smoke, or wind effects). Static elements like the fence and distant figures remain consistent across frames.
