A man in a purple polo shirt, white shorts, white cap, and gloves holds a golf club, turns his back, and walks toward another man in the background. The second man, wearing a green shirt and dark shorts, stands near a white marker, bends down, then stands and walks away. The camera follows the first man’s movement with a slight pan left.

Two individuals (one in purple shirt/golf attire, one in dark shirt) exhibit discrete motion: the foreground person is manipulating a golf club (preparing to swing), while the background person is stationary or moving minimally; both are solid, distinct objects with locomotion/controlled motion.

Background elements (sky, distant trees, grass) show no uniform shifting; subtle grass sway suggests minimal wind but no dominant ambient environmental motion (no fire, water, or smoke).


A person with short light brown hair lies on a beige couch, initially with their mouth open, then closes it, and subsequently lifts their right hand to adjust an earbud in their right ear. The camera maintains a close-up, fixed perspective throughout the sequence.

A person is moving their head and arms, exhibiting natural body motion (e.g., talking, facial expressions, hand movement to the ear).

The background (couch and wall) is static with no shifting. No fluid or environmental motion (fire, water, wind) is present.


RAW CAPTION: Okay, let me tackle this video captioning task. First, I need to understand what's required. The user wants a concise chronological paragraph describing the video, following specific rules.

The video starts with a star-shaped watermelon slicer on a red surface. Then a hand appears on a watermelon, holding it steady while a knife cuts it. The rules say to focus on motion and behavior in order, mention appearance and number, spatial relationships, camera perspective, and keep background minimal.

So first scene: slicer is white with green handles, star-shaped, red background. Then transition to hand on watermelon. The hand is a man's hand, maybe with some dirt, holding the watermelon. The knife is cutting through it. The camera is top-down initially for the slicer, then shifts to the hand and watermelon.

Wait, the first frame shows the slicer, then next frames are the hand on the watermelon. So chronological order: first the slicer is shown, then the hand holding the watermelon while cutting. Need to mention the slicer's color (white, green handles), shape (star), then the watermelon (green with dark stripes), hand (adult male, with dirt on nails), and the action of cutting. The camera perspective starts top-down for the slicer, then stays close-up on the hand and watermelon. Background is red in both, but minimal as per rules.

Check the rules: exclude text recognition (R73 (2016) is text, but rule f says exclude named characters or text, so probably omit that). The caption should avoid mentioning the text in the corner. So the first frame has the slicer, then the hand on the watermelon.

Wait, the first frame is the slicer, then the next frames are the hand. So the video sequence is: slicer shown, then hand on watermelon. So the caption needs to describe that sequence.

Make sure to mention the order: first, the slicer is shown (white with green handles, star-shaped), then a hand (adult male, with visible dirt on nails) places on a green watermelon with dark stripes, and a knife cuts through it. The background is red in both, but keep it minimal. Camera starts top-down, then close-up on the hand and watermelon.

Check if there are multiple objects: the slicer is one object, then the watermelon and hand. So main subjects are the slicer, hand, watermelon, knife. But the rules say focus on motion and behavior. So the slicer is stationary, then the hand moves onto the watermelon, and the knife cuts.

Wait, the video starts with the slicer, then cuts to the hand on the watermelon. So the first part is the slicer, then the action of the hand and knife. So the caption should mention the slicer first, then the hand holding the watermelon while the knife cuts.

Also, the hand is pressing down on the watermelon as the knife slices it. So describe the hand's position (on the watermelon, fingers spread), then the knife cutting through.

Check the rules again: mention appearance (color, size, orientation) of main subjects. Slicer: white with green handles, star-shaped. Hand: adult male, visible dirt on nails. Watermelon: green with dark stripes. Knife: silver, cutting.

Spatial relationships: the hand is on the watermelon, knife is to the right of the hand, cutting through.

Camera perspective: starts top-down (first frame), then remains close-up on the hand and watermelon.

Need to keep it concise. Let's structure the caption step by step.

1. Initial shot: A white star-shaped watermelon slicer with green handles sits on a red surface.
2. Then, a hand (adult male, visible dirt on nails) presses onto a green watermelon with dark stripes, holding it steady as a knife slices through it.
3. Background remains red, camera stays top-down then close-up.

Wait, the first frame is the slicer, then the next frames are the hand. So the transition from slicer to hand. So the caption should note the sequence.

Avoid mentioning the text (R73 (2016)), as per rules.

Check for chronological order: slicer shown first, then hand on watermelon with knife cutting.

So the final caption should start with the slicer, then the hand action.

Let me draft it:

"The video begins with a white star-shaped watermelon slicer featuring green handles resting on a red surface. It transitions to a close-up of an adult male’s hand, marked with visible dirt on the nails, pressing against a green watermelon with dark stripes. The hand holds the watermelon steady as a knife slices through it, maintaining a top-down perspective throughout."

Check if it's concise,

The hand and knife are moving to cut the watermelon, which is a discrete object physics interaction.

The background is a solid red color, static and unchanging. There are no fluid or environmental motions present.


A person in a white shirt with a black undershirt seasons a large raw turkey in a roasting pan with a red pepper grinder. The turkey, already coated with yellow spices, is positioned on a countertop. The person moves the grinder over the turkey's surface, releasing pepper. The camera remains stationary, focusing on the seasoning action against a kitchen backdrop with stovetop and containers visible.

A person's hand and arm are moving to pour liquid from a red container over a turkey in a roasting pan; the turkey remains stationary while the hand exhibits discrete motion from the pouring action.

The kitchen background (stove, cabinets, windows) shows no uniform shifting or fluid motion (e.g., fire, water, wind), indicating no dominant ambient environmental motion.


Three girls in light-colored outfits engage in a pillow fight in a bedroom; one in a green dress throws a pillow while another in a white dress dodges. The scene transitions to a chaotic bedroom where multiple children, including a girl in a purple top and white shorts, aggressively swing pillows and run across the room. The girl in purple confronts another child near a bed with a patterned cover, then sprints toward the bed as pillows fly. Camera work shifts from static to shaky handheld, panning left to follow motion, capturing blurred movements against minimal background details.

Discrete solid objects (people, pillows) are moving due to explicit physical interactions (throwing, dodging, collisions) as participants engage in a pillow fight.

Background elements (bookshelves, lamps, bed) remain stationary and show no uniform shifting or fluid/environmental motion (fire, water, smoke, wind) throughout the sequence.


A man in a red and white checkered shirt with a dark necklace holds a cup, then smiles while interacting with a blonde woman; his hand adjusts her hair as he leans toward her, and he continues to engage with her in a close setting. The background remains blurred, emphasizing their interaction, with the camera focusing on close-up shots of their faces and hands before shifting to a wider view of the man leaning forward.

The man is actively moving his hands to cut and style the woman's hair; the woman's hair is displaced by the cutting action.

The background (room interior) is static in each shot. No fire, water, smoke, or wind visible.


RAW CAPTION: Got it, let's break down the video. First, the main subject is a person in a dark blue shirt with a logo, handling red plastic cups. The cups are initially stacked into a pyramid. The person starts by moving the cups—maybe building or rearranging. Then the timer changes from 368 to 589, then 600. The person stands up, raises their arms, and the timer shows 600. The background has a kitchen setting with cabinets, a window, a bottle, a small container, and a yellow package on the table. The camera is static, right? Let's check the rules: focus on motion, chronological order, appearance, spatial, conclude with camera.

First frame: person arranging red cups (stacked pyramid). Then they rearrange the cups—move them from stack to a line? Wait, in the first frame, cups are in a pyramid (three tiers maybe). Then in the second frame, the person moves cups to form a different arrangement, like a tower. Wait, the video frames: [0.0] cups are a pyramid. [1.4] cups are being moved, maybe into a line. [2.5] cups are stacked again? Wait, the description says "rearranging the cups"—the person is moving the cups, then stands up.

Wait, the sequence: starts with a stack of red cups. The person moves the cups, maybe to rearrange. The timer starts at 368, then increases to 478, 589, 600. The person is the main subject, moving cups. Then stands up, raises arms.

So chronology: person in dark blue shirt interacts with red plastic cups. Initially, cups are stacked (pyramid). Person adjusts cups, forming a new arrangement (maybe a tower). Timer shows 368, then 478, 589, 600. Person stands up, raises both arms. The table has a bottle, small container, yellow package. Background is kitchen with cabinets and window. Camera is static, no movement.

Need to describe motion: person manipulates red cups (stacking, rearranging), timer increases, then stands and raises arms. Appearance: red cups, dark blue shirt. Spatial: cups on table, bottle to the left of cups.

Let's structure:

A person in a dark blue shirt rearranges red plastic cups on a table. Initially, cups form a pyramid; the person then moves cups to form a tower. The digital timer displays increasing numbers (368 to 600) as the person adjusts the cups. The person then stands, raises both arms, and the timer reaches 600. The table also holds a blue mat, a bottle, a small container, and a yellow package to the left of the cups. The background features kitchen cabinets and a window. The camera remains static throughout.

Wait, check rules: exclude text recognition (like "368" as text, but the timer's display is part of the scene, but the instruction says exclude text recognition? Wait, rule f says "Exclude text recognition, named characters, or stylistic analysis." Oh! So we can't mention the timer's numbers. Oh right, that's a rule. So the timer is part of the scene but the numbers are not to be mentioned. So instead, say "the timer shows a digital display increasing" but without the numbers. Wait, the rules say "exclude text recognition" so we can't mention the actual numbers. So just describe that the timer is displaying a number and increasing, but don't specify the numbers.

Wait, let's check the rules again: "Exclude text recognition, named characters, or stylistic analysis." So text recognition means not mentioning the text on screen (like the timer's numbers). So instead of "timer shows 368", say "a digital timer shows a numerical display increasing".

So revising:

A person in a dark blue shirt rearranges red plastic cups on a table. Initially, the cups form a pyramid; the person moves them to create a tower arrangement. A digital timer with a numerical display increases as the person adjusts the cups. The person then stands, raises both arms, and the timer continues to increase. The table also holds a blue mat, a bottle, a small container, and a yellow package positioned to the left of the cups. The background includes kitchen cabinets and a window. The camera remains static throughout the sequence.

Check chronological order: first, rearranging cups (pyramid to tower), then timer increases, then stands and raises arms. Correct.

Appearance: red cups (multiple, stacked), dark blue shirt. Spatial: cups on table, other items to the left. Camera: static.

Yes, that should work. Let's make sure

The person (wearing blue shirt) is actively moving: rearranging red cups on the table, then standing up and raising arms. The cups are moved by the person's hands and are solid objects.

The background (kitchen cabinets, walls, window) is static. No fire, water, smoke, or wind is present. The scene is controlled and calm.


A child with pink hair, wearing a yellow jacket with gray sleeves, sits on a green surface. A man enters from the right, bends down, and kisses the child on the forehead. The camera remains mostly static with slight movement.

Two distinct solid objects (a child and an adult) are moving: the child's head and body shift position while the adult enters the frame, leans toward the child, and makes physical contact. Their motion is due to intentional locomotion and interaction.

The background consists of static tiled walls and a countertop with no shifting or environmental fluid motion (fire, water, smoke, wind). The tiles remain uniformly fixed throughout the sequence, indicating no ambient environmental forces dominating the scene.


A pair of hands with light blue nail polish manipulates purple yarn and wooden knitting needles. The left hand holds the needle with the ongoing stitch while the right hand guides the yarn to form a new loop around the right needle, then pulls the yarn through to complete the stitch. The hands repeat this sequence, moving the needles in a coordinated motion to advance the knitting. The camera maintains a close-up, top-down perspective focused on the hands and needles, with a light, neutral background.

Hands and knitting needles moving in a controlled manner to manipulate yarn; the motion is due to physical actions of knitting.

Static background (white wall) with no shifting elements. No ambient environmental motion (fire, water, wind, etc.) observed.


A female athlete in a black tank top, black pants, and white shoes runs toward the high jump bar on a blue indoor track. She leaps over the bar, landing on the blue mat, while a person in dark attire stands nearby. The camera pans left, following her motion, capturing the sequence in a gymnasium setting.

A female athlete in black sportswear is running and jumping over a bar; another female athlete in a black and gold outfit is standing and then moving to the side.

The background elements (walls, mats) are stable with no uniform shifting or fluid motion (fire, water, smoke, wind) observed.


A person in a red shirt raises their right hand to their head, then lowers it while turning their head slightly. They smile broadly, maintaining eye contact with the camera. The background is a plain white wall, and the camera remains static with no noticeable movement throughout the sequence.

The main moving object is the boy (in a red shirt) speaking and moving his head/mouth. No other solid objects exhibit discrete motion.

The background is a static wall with no fluid or environmental motion (fire, water, smoke, wind). The cartoon sticker is an overlay and does not constitute environmental motion. No background elements shift uniformly.


A light-skinned hand enters from the right, moving across dark, moist soil mixed with twigs and dried leaves, then shifts leftward, disturbing the ground and revealing more debris before exiting the frame. The camera maintains a close-up perspective with slight movement.

A hand is moving, interacting with the soil and small creatures (e.g., worms, insects). The hand is displacing the soil and the small creatures, causing them to move.

The background consists of soil, sticks, and leaves with no significant shifting (no fire, water, smoke, or wind effects). The ground remains static except for localized disturbances caused by the hand.


A woman in an orange tank top holds a black and pink dumbbell in front of her, then lifts it upward toward her chest while standing in a gym with weight equipment visible in the background. The camera remains stationary, focusing on her upper body movements.

The woman is performing a bicep curl exercise, moving her arm and holding a dumbbell in discrete object physics motion.

The background (gym equipment and walls) is stationary; no fire, water, smoke, or wind motion observed.


A person wearing a red swim cap and blue swim trunks swims underwater, moving forward with arms extended and legs kicking, generating bubbles as they glide. The seabed below has scattered debris. The camera remains fixed underwater, capturing the swimmer's motion from a frontal perspective.

A single swimmer (discrete human subject) moves through water via swimming locomotion, with clear bounding box tracking of body position and limb movements.

The underwater seabed (static sand/rock) shows no uniform shifting. Water as a fluid medium is present but not the dominant motion; it serves as the context for the swimmer’s movement.


RAW CAPTION: Got it, let's tackle this. First, I need to describe the video in chronological order. The video shows hands massaging feet. Let's break down each frame.

Frame 0: Close-up of hands on a foot, maybe the ankle. The hands are interlocked, pressing. The foot is light-skinned, maybe a bit hairy? Wait, the foot in the first frame is on a surface, maybe a towel.

Frame 1: Still hands on foot, maybe shifting a bit. The foot is still there.

Frame 2: Now, the camera shifts to a wider shot? Wait, the description says "a person's feet on a white towel. One foot is being massaged by hands."

Wait, the user provided 5 frames, but the example shows [0.0], [1.4], [2.5], [3.6], [4.7]. So each frame is a moment. Let's see:

First frame: hands pressing on a foot, probably the ankle area. The foot is light skin, with some hair. The hands are also light skin, maybe the masseuse.

Second frame: Maybe the hands are moving, still on the foot.

Third frame: The camera shows a wider angle, showing the person's legs and the foot on a white towel. So now, the foot is visible more, with the ankle and foot.

Fourth frame: Close-up on the foot being massaged, hands pressing on the sole?

Fifth frame: Close-up of hands on foot, maybe pressing the arch or toes.

Wait, the task is to describe chronologically. So start from the first frame (0.0) and go to the last (4.7).

First part: At the start, close-up of hands gripping a foot, likely performing a massage. The hands are light-skinned, the foot is light-skinned with visible hair. Then, the camera shifts to a wider view showing the foot on a white towel, with the person's legs partially visible. The hands continue massaging the foot, moving from the ankle towards the sole. Next, the hands are seen pressing the sole of the foot. Finally, the hands are still massaging, focusing on the arch area.

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

0.0: Close-up of hands massaging a light-skinned foot (with some hair), hands light-skinned, gripping the foot.

1.4: Slight shift, hands still on foot, maybe pressing more.

2.5: Wider shot showing the foot on a white towel, legs visible, hands massaging the foot from ankle.

3.6: Close-up on hands pressing the sole of the foot.

4.7: Close-up of hands continuing to massage the foot's arch.

Now, put it into a paragraph. Mention the motion chronologically. Start with the first frame: hands massaging foot in close-up. Then the camera shows a wider view with the foot on a towel, then hands moving to sole, then arch.

Check the rules: focus on motion and behavior, chronological. Appearance: light-skinned hands and foot, white towel. Spatial: hands on foot, foot on towel.

Conclude with camera perspective: starts close-up, then shifts to wider, then close-ups again. But need to mention camera movement. The video starts with a close-up, then transitions to a wider shot, then close-ups on different parts.

Wait, the camera movement: "close-up" initially, then "wider shot", then "close-up on sole", then "close-up on arch".

So the caption should say:

A pair of light-skinned hands massages a light-skinned foot with visible hair in a close-up view, then the camera shifts to a wider angle showing the foot resting on a white towel with the person’s legs partially visible as the hands continue massaging the ankle and sole. Subsequent frames show the hands pressing the sole and arch of the foot in close-up shots.

But need to be concise. Let's check:

- Chronological: start with first action (massaging foot close-up), then wider view, then sole, then arch.

- Appearance: light-skinned hands and foot, white towel.

- Spatial: hands on foot, foot on towel.

- Camera: starts close-up, then wider, then close-ups.

Let's draft:

The video begins with a close-up of light-skinned hands massaging the ankle and foot of a light-skinned person with visible hair, then transitions to a wider shot showing the foot on a white towel as the hands continue massaging the foot, followed by close-up shots focusing on the sole and arch of the foot being massaged.

Check rules:

a) Motion and behavior: hands massaging foot, moving from ankle to sole to arch.

b) Appearance: light-skinned hands and foot, white towel.

c)

Hands and a foot are moving due to explicit physical contact during a massage. The foot shows slight displacement as the hands manipulate it, indicating discrete object physics from human locomotion and force application.

The background (bed sheets and surrounding area) is static with no visible fluid or environmental motion (e.g., fire, water, wind). No shifting background elements indicate camera-induced motion.


RAW CAPTION: Got it, let's tackle this. First, the video starts with "ROUND 1" text, but I need to ignore that per rule f. The main subjects are two people. Let's see the sequence.

At [0.0], there's a person on the left (maybe moving), then in [1.0], another person enters from the right. Wait, first frame: left side has a person moving, then at [1.0] (second frame), the person on the left is still there, and another person (right) appears. Wait, the first frame: person on left is partially visible, then next frame (1.0) shows a person in gray shirt on left moving, and a person in black on the right. Let's check the motions.

Frame 0.0: left side, a person (light clothing) is moving, maybe walking. Then at 1.0: left person in gray shirt is moving left, right person (black shirt, dark pants) is moving towards the right. Wait, frame 2.0: left person is still moving left, right person is now near the wall. Frame 3.0: left person stops, right person moves towards the center. Frame 4.0: left person is now on the left side, right person bends down. Wait, maybe better to list each frame's action.

From frame 0 to 5:

0.0: two people, one on left (light shirt, moving), one on right (dark shirt, moving towards center). Wait, first frame: left person is partially visible, then in frame 1, the right person is moving into the frame.

Wait, the video shows: first, a person on the left (gray shirt) moves across the frame from right to left. Then, a person on the right (black shirt, dark pants) enters from the right and moves towards the center. Then the gray-shirted person moves left, the black-shirted person moves towards the wall, then bends down.

So chronological order:

- A person in a gray shirt is initially seen on the left, then moves left across the frame. Simultaneously, a person in black clothing enters from the right and moves towards the center. The gray-shirted person exits the frame to the left. The black-shirted person moves towards a wall, bends down, and then interacts with something (maybe a bag on a chair). Background has a wall with lights, a curtain, and a bag with a blue light. Camera is static, maybe slight shake, but rule d says camera perspective and movement. It's a fixed camera, maybe handheld (slight shake).

Now, rule a: motion and behavior in chronological order. So:

In the opening frames, a person in a gray shirt moves left across the frame, while another person in black clothing enters from the right and moves toward the center. The gray-shirted individual then exits left, and the black-shirted person bends down near a chair with a bag.

Rule b: mention appearance and number. Two people: one gray shirt, one black shirt. Size: medium, since they're in a room.

Rule c: spatial relationships. Gray-shirted person on left, black-shirted on right initially, then moves toward center, then to the wall.

Rule d: camera is static, maybe slight shake, but the problem says "top-down, pan left, slight shake" – but here, it's a medium shot, static. So "static camera with slight shake."

Rule e: background minimal. The room has a wall with lights, curtain, chair with bag – but keep minimal, so maybe "dimly lit room with a wall, curtain, and chair" but rule e says minimal unless essential. Since the bag is on the chair and the people move around it, maybe essential. But focus on motion.

Putting it all together:

A person in a gray shirt moves left across the frame while another person in black clothing enters from the right, moves toward the center, exits the frame left, and then the black-shirted individual bends down near a chair with a bag. The scene occurs in a dimly lit room with a wall, curtain, and chair. The camera is static with slight shake.

Check rules:

a) motion chronological: yes.

b) appearance and number: two people, gray and black shirts.

c) spatial: gray left, black moves right then center.

d) camera: static slight shake.

e) background minimal: "dimly lit room with wall, curtain, chair" – but maybe too much. Wait, rule e says "keep background descriptions minimal unless essential for understanding motion." The motion involves the chair with bag (they interact with it), so maybe include "chair with bag" but not much else.

Finalize:

In the video, two individuals are present: one wearing a gray shirt

Two human figures are moving: one approaches the wall, interacts with it, bends down, and exits; another figure on the left moves slightly. These are distinct solid objects (people) exhibiting locomotion and interaction with the environment.

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


A light brown tabby cat with distinct stripes sits in a white tub. A hand holding a handheld showerhead directs water over the cat’s body, moving the showerhead from the cat’s torso to its legs and lower body while the cat remains still, occasionally shifting its gaze. The hand and showerhead are positioned to the left of the cat, maintaining close proximity as water flows onto the cat’s fur. The camera maintains a steady top-down perspective throughout the sequence.

A hand holding a hairdryer and a cat are the discrete objects. The cat moves its head and body in response to the hairdryer's airflow, while the hand adjusts the hairdryer's position.

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


A young child in a light-colored patterned shirt sits at a wooden kitchen table, leaning forward to eat a muffin from a white plate. The child lifts the muffin, takes a bite, and turns their head while seated between wooden chairs, with kitchen cabinets and stools visible in the background. The camera, handheld and slightly shaky, pans around the child to capture their actions from various angles.

The child is moving their head and mouth to blow out the candle, which is a discrete solid object (person) moving due to explicit physical forces (blowing).

The background (kitchen cabinets and stool) remains mostly static with no uniform shifting. The candle flame is burning but is not dominant and is a small part of the scene.


A person with flour-covered hands manipulates three white dough balls on a white countertop in a kitchen, moving and shaping them. The camera transitions from a wide view of the workspace to a close-up of the hands and dough, focusing on the rolling motion.

The person's hands are manipulating the dough (rolling and shaping). The dough is a solid object being moved by the hands due to physical forces (rolling, pressing).

No shifting background elements; no fluid or environmental motion (fire, water, wind, etc.) observed.


A woman in a yellow sari with green border holds a blue patterned cloth, surrounded by a dense crowd of people in various colored traditional garments. She adjusts and moves forward with the cloth as others assist, some reaching toward it from the sides. The camera follows her motion with a slight handheld shake, capturing the group’s interaction in a close-up, dynamic perspective.

The woman in the yellow sari and the surrounding crowd are moving due to interactions (handing a blue cloth, shifting positions).

The background (trees, structures) is stable with no uniform shifting. No fire, water, smoke, or wind-dominated motion is observed.


A woman in a long, dark brown patterned dress dances in a public plaza, moving her arms and twirling as she steps forward. A second woman in a white top with a pink bag approaches her from the right, briefly interacting before stepping back. The dancer continues rotating, her dress flowing, while a man in a blue vest walks past in the background. The camera follows the dancer’s motion, panning slightly left and right with a subtle shake, capturing her movements from multiple angles as onlookers sit on stone steps nearby.

The main moving objects are a woman in a long black dress performing a dance (moving arms and body) and a girl in a white shirt walking away and clapping. Other people in the background are either stationary or moving minimally.

The background elements (steps, trees, buildings) are stationary and show no uniform shifting. No fluid or environmental motion (fire, water, wind) is prominent.


A single finger moves across a Sudoku grid on a screen, tapping various cells in sequence: starting near the top right, then moving leftward, downward, and rightward. The grid features brightly colored cells (including yellow, blue, and green highlights) with some filled. The camera remains in a static top-down view, focused on the grid and finger interaction.

A pencil (discrete solid object) moves across the screen to point at specific Sudoku cells, indicating intentional human interaction.

Background elements (Sudoku grid, numbers, screen interface) show no shifting or fluid motion; no fire, water, or wind present.


Two men are inside a confined vessel. A man in a navy shirt holds a blue pole with his left hand while a man in a light blue shirt uses a white hose to groom his head. The light blue-shirted man adjusts the hose over the navy-shirted man’s head, who occasionally turns slightly. The camera shifts between top-down and side views, capturing their interaction.

Two people: one seated (head turning slightly) and one standing (moving hands to cut hair with scissors). The scissors and hair are the discrete objects in motion.

No shifting background or fluid/environmental motion; the workshop setting is static with no fire, water, or wind.


A person in a blue cable-knit sweater sits at a wooden table, manipulating a circular wooden object with a small tool. They lift the tool to display it, then gesture toward the table where two similar wooden pieces, scissors, a pink thread spool, and a blue marker lie. The camera maintains a static overhead perspective.

The woman's hand and pen are moving as she writes on a circular object (likely a cookie) on the table. The circular objects and pens on the table are stationary except for the pen in motion.

The background (shelves with decorations and framed items) remains static throughout the clip. No fluid or environmental motion (fire, water, smoke, or wind) is observed.


A baseball catcher wearing a blue shirt, orange pants, and helmet starts crouched behind home plate on dirt. He rises to a standing position, steps forward slightly, then returns to a crouched stance. The background includes parked cars and a building, with the camera remaining stationary throughout.

The baseball player undergoes discrete motion: crouching into batting stance, swinging the bat, and stepping off the base. The car in the background exhibits slight movement due to locomotion but is secondary to the player's actions.

The background elements (cars, structure, ground) remain static throughout. No fluid or environmental motion (fire, water, smoke, wind) is present. Minor background car movement is observed but is not dominant and falls under discrete object locomotion.


RAW CAPTION: Got it, let's break down the video. First scene: a close-up of a hand pouring a light-colored liquid (maybe milk or yogurt) from a metal container into a white cup. The cup is on a stainless steel counter. Then, the next scene shows two white cups on the counter, with a person in a white shirt holding one, and another person in an orange shirt using a dispenser to pour into the other cup. Then, a hand with a ring picks up one of the cups. Next, a person in a white shirt uses a spoon to scoop something (maybe food) from a plate into the cup. Wait, the video has multiple clips. Let's check each frame.

Frame 0: Close-up of a hand pouring liquid into a white cup. Cup is on metal counter. Background is blurred kitchen area.

Frame 1: Two white cups on counter, someone (left) holds one cup with their hand, another person (right) uses a dispenser to pour into the other cup. Background is people in a busy kitchen.

Frame 2: Similar, two cups, a person in white shirt holds a cup, another in orange shirt pours into the second cup.

Frame 3: A person in a blue sleeve holds a cup, then moves it. The cup has a light-colored liquid.

Frame 4: A metal container with a spoon, then a tray with fried items (like samosas), a plate with a white substance (maybe yogurt or cream), and a bowl with green food (maybe chutney).

Now, the caption needs to be chronological. So order of events: pouring into a cup, then two cups being filled, then handling the cups, then the tray with food.

Main subjects: hands, people (in different shirts), cups, dispenser, food items.

Chronological:

- First, a hand pours liquid into a white cup on a metal surface.

- Then, two white cups are placed on the counter, with one person holding a cup and another using a dispenser to fill the second cup.

- A hand with a ring picks up one cup.

- Later, a person scoops food into a cup (from the tray with fried items).

Spatial: cups on counter, people around.

Background: busy kitchen, but minimal.

Camera: close-up, then medium shots, moving between actions.

Check the rules: focus on motion and behavior, chronological. Don't mention text (FYNDRS is logo, exclude). Mention appearance: white cups, stainless steel counter, people in different colored shirts (white, orange, blue), food items like fried snacks.

Need concise paragraph.

Let's structure:

A hand pours a light-colored liquid into a white cup on a stainless steel counter. Next, two white cups sit on the counter as a person in a white shirt holds one while another in an orange shirt uses a dispenser to fill the second cup. A hand with a ring then lifts one cup. Subsequently, a person in a white shirt scoops food from a tray of fried items into a cup, with additional items like a white plate and green condiment nearby. The camera alternates between close-up shots of hands and cups and medium shots of the kitchen area, maintaining focus on the pouring and handling actions.

Wait, check frame 4: there's a tray with fried food (maybe samosas), a plate with white stuff (like yogurt), and a bowl with green (chutney). So in the sequence, after the cups, the scene shows these items.

Wait the video frames are:

[0.0] - pouring into cup

[1.4] - two cups, someone holds one, another pours into second

[2.5] - similar, two cups

[3.6] - hand holding a cup

[4.7] - tray with fried items, plate, etc.

Wait the video has 5 frames. Let's list the order:

Frame 0: Close-up of a hand pouring liquid into white cup (metal counter, background blurred kitchen)

Frame 1: Two white cups on counter; person in white shirt holds one cup, person in orange shirt pours from dispenser into the second cup.

Frame 2: Similar to frame 1, maybe a bit different angle.

Frame 3: Person in blue sleeve holds cup, then moves it.

Frame 4: Tray with fried food (like samosas), plate with white substance, bowl with green food.

So the sequence is:

- Pouring liquid into a cup.

- Two cups on counter, pouring into the second.

- Hand holding a cup.

- Tray with food items.

So the caption should be chronological: start with pouring, then the cups, then handling, then the tray.

But need to make sure it's concise.

Let's draft:

A hand pours a light-colored liquid into a white cup on a stainless steel counter. Two white

Discrete objects (cups, hands of people) exhibit motion: pouring liquid into cups and moving cups across the counter.

No shifting background elements observed; no fluid, gaseous, or wind-driven environmental motion (e.g., fire, water, smoke) dominates the scene.


A man in a black shirt holding a pink balloon octopus walks through a crowded indoor space, moving toward a woman in a white shirt who accepts the balloon. He extends the balloon toward her as she stands amidst seated and standing onlookers. The camera follows his movement with slight motion, capturing the handoff and surrounding crowd activity in the background.

Pink balloon sculpture (solid object) is manipulated by a person (balloon artist) and transferred to a woman; human locomotion and hand movements drive discrete object motion.

Static background elements (walls, chairs, distant people) show no uniform shifting; no fire, water, smoke, or wind present.


tags, no extra text. So the caption should flow from start to end. Let me draft:  "A woman with blonde hair, wearing a black sleeveless top, black pants with white patches, and sneakers, practices boxing motions in a gym. Facing a large mirror, she throws punches and steps back while her reflection mirrors her movements. Punching bags are visible against the wall behind her. The camera remains stationary with a slight shake, capturing her from behind."  Check the rules: chronological order, mention appearance and number (only one woman), spatial relationships (mirror behind, punching bags in background), camera perspective (stationary, slight shake). Background minimal, yes. No text, names excluded. Okay, that seems to fit. </think>  <caption_output>A woman with blonde hair, wearing a black sleeveless top, black pants with white patches, and sneakers, practices boxing motions in a gym. Facing a large mirror, she throws punches, steps back, and continues striking while her reflection mirrors her movements. Punching bags are visible against the wall behind her. The camera remains stationary with a slight shake, capturing her from behind.

A woman is dancing, performing rhythmic arm and leg movements in a dance studio.

Background elements (walls, mirror, floor) are stationary; no ambient environmental motion (fire, water, smoke, wind) detected.


A person’s hand adjusts a bicycle’s front wheel, initially focusing on the handlebar before shifting to the wheel as it is rotated and repositioned against a plain wall. The camera follows the wheel’s movement with minimal background detail, capturing the motion of the hand and the wheel’s reorientation in close-up.

A bicycle wheel is being manually rotated by a person, indicating solid object motion driven by physical force (human manipulation).

The background consists of a static wall with no shifting or environmental motion (e.g., fire, water, wind) observed.


A shirtless toddler wearing brown pants crouches on a light wooden floor, holding a white bowl. The child stands, turns, and walks rightward while carrying the bowl toward a dark cabinet. The camera remains top-down and stationary.

Baby (discrete object) crawls on floor while manipulating a small toy container; toy moves due to baby's physical interaction and locomotion.

No shifting backgrounds observed; static furniture (chair, TV stand) remains fixed. No fluid/environmental motion (fire, water, smoke, wind) present.


A person in a blue patterned dress and glasses raises their hands, then reaches to the right to pick up a blue box with a pink design and a white object from a surface. They hold both items up, displaying them. The camera remains stationary.

Person (discrete solid object) moves arms, adjusts clothing, picks up a blue rectangular object, and holds it while interacting with a large screen/monitor. Motion is deliberate, physical movement without environmental fluidity.

Static background elements (wall with 'DEE EAM' sign, shelves) show no uniform shifting or fluid motion (fire/water/smoke/wind).


Hands manipulate three sushi rolls on a light-colored cutting board, with two rolls displaying red accents and one partially sliced; a black-handled knife rests to the right. The person, wearing a blue shirt with white floral patterns, picks up a roll and places it onto a small wooden board. The camera shifts to a wider angle, showing the person standing at the counter with minimal background items visible.

Discrete solid objects (sushi rolls, hands) exhibit motion due to explicit physical forces (manual manipulation by the person). The hands actively reposition and handle the sushi rolls.

The background elements (countertop, knife, containers) remain static throughout the frames; no shifting backgrounds or fluid/environmental motion (fire, water, smoke, wind) is present.


RAW CAPTION: Got it, let's tackle this video captioning task. First, I need to watch the video frames and note the key elements. The video shows a fenced area, probably a farm or animal enclosure. There's a person and a dog. Let's break it down chronologically.

Starting with frame 0: a person (wearing a dark shirt and jeans, maybe a backpack) stands near the fence, and a black dog is in the dirt area. Then, in frame 1-2, the person moves towards the right, and the dog is moving too. Wait, in frame 3, the person is further right, then frame 4: a light-colored dog (maybe a sheepdog?) comes into view. Frame 5: more dogs, maybe a few, moving towards the person.

Wait, the video starts with a person and a black dog. Then the person walks, and other dogs (light-colored, maybe multiple) appear and move towards the person. The camera seems to pan right slowly. Background has fences and trees, but minimal.

Need to list chronological events: first, the person (male, dark shirt, jeans, backpack) stands near the fence with a black dog. Then the person walks right, and a light-colored dog (maybe two or three) enter the frame, approaching the person. The camera moves slightly right, following the person's movement.

Check appearance: person is tall, dark top, blue jeans, backpack. Black dog first, then light-colored dogs (maybe 2-3, medium size). Spatial: person is behind the fence, dogs in the enclosure. Camera perspective: the video is framed as if viewed through a screen (like a phone or monitor), but the camera itself is panning right.

Wait, the rules say focus on motion and behavior in chronological order. So first frame: person stands with black dog. Then person moves right, dog moves. Then light-colored dogs (maybe 2-3) appear from the right (since the camera is panning right) and approach the person.

Let me structure it: A person in a dark shirt and blue jeans stands near a metal fence, accompanied by a black dog. The person then walks right, and a light-colored dog enters the frame, followed by more light-colored dogs. The camera pans right to follow the movement, maintaining a medium shot of the enclosure.

Wait, check the frames:

Frame 0: person and black dog.

Frame 1: person moves slightly, dog moves.

Frame 2: person is moving right, dog is moving.

Frame 3: person is at the right edge, and maybe a light-colored dog is coming from left? Wait, the video sequence: the camera is moving right, so the left side of the frame is the person moving left? No, the camera is panning right, so the person is moving towards the right, and the camera follows.

In frame 3, the person is further right, and a light-colored dog appears from the right side (since the camera is panning right). Then frame 4, more light-colored dogs.

So step by step:

- Initially, a person (dark shirt, blue jeans, backpack) stands near a metal fence in a dirt enclosure with a black dog.

- The person walks right along the fence, while the black dog follows.

- As the person continues moving right, light-colored dogs (2-3 medium-sized) enter the frame from the right and approach the person.

- The camera pans right to follow the movement, keeping the person and dogs in the center.

Background: trees and fences outside the enclosure, but minimal details. No need to mention background unless essential.

So the caption should be concise, chronological.

Let me draft:

A person in a dark shirt and blue jeans, carrying a backpack, stands near a metal fence in a dirt enclosure with a black dog. The person then walks right along the fence, while the black dog follows. As the person continues moving right, two light-colored medium-sized dogs enter the frame from the right and approach the person. The camera pans right to follow the movement, maintaining a medium shot of the scene.

Check the rules:

- Focus on motion and behavior chronologically: yes.

- Appearance and number: person (dark shirt, blue jeans, backpack), black dog first, then two light-colored dogs.

- Spatial relationships: person walks right, dogs enter from right and approach.

- Conclude with camera: pans right.

- Background minimal: yes, "dirt enclosure" is enough.

- Exclude text, named characters: no names.

Good. Let's check if it's concise.

Alternative:

A person in a dark shirt and blue jeans with a backpack stands near a metal fence in a dirt enclosure with a black dog. The person walks right along the fence as the black dog follows. Two light-colored medium-sized dogs then enter from the right, approaching the person

A person in a blue shirt and a dark-colored animal (likely a dog) exhibit distinct locomotion within the fenced area. Their movement is tracked as discrete entities moving due to physical motion (walking, running).

Background elements (fence, trees, ground) remain stationary across frames, with no signs of fire, water, smoke, or wind-driven motion. No uniform shifting of static elements indicates no ambient environmental dominance.


A person is moving by walking and throwing darts; the darts are projectiles moving through the air.

The background (dartboard, wall, and lights) is static with no shifting or environmental motion. No fire, water, smoke, or wind is present.


RAW CAPTION: Got it, let's break this down. The video shows a person cutting a large wooden object, maybe a piece of wood or a log. The person's hands are visible, holding the wood with one hand and using a saw with the other. The background has a house, a red umbrella, and some outdoor furniture.

First, identify the main subject: the person's hands. The action is cutting the wood. The wood is light brown, large, and held upright. The person is wearing a white cap with a logo. The saw is metallic, being pulled through the wood.

Chronological order: The person starts cutting, the saw moves through the wood, and the wood splits as the saw progresses.

Spatial relationships: The person is outdoors, in front of a house with a red umbrella to the right. The house has a wooden door and a flower basket.

Camera perspective: It's a close-up shot focusing on the hands and the wood. The camera is stable, maybe slightly zoomed in on the action.

Background: Minimal, but the house and umbrella are visible.

Now, structure the caption. Start with the action, describe the subject, then the motion, then background briefly. Keep it concise.

Check the rules: no text recognition, don't mention names. Focus on motion, appearance, spatial, conclude with camera.

Let me draft:

A person uses a hand saw to cut through a large, light-brown wooden piece held vertically. Their hands grip the wood and saw, pulling the blade through the material as it splits. The scene occurs outdoors near a house with a red umbrella to the right, featuring a wooden door and flower basket. The camera remains steady, closely focused on the cutting action.

Wait, need to check the order: chronological. The action starts with cutting, then continues. Also, mention the person's appearance briefly: the cap? But rule b says "briefly describe their appearance and number". The person is partially visible, wearing a white cap with a logo, but maybe "a person" is enough. Wait, the rules say "appearance and number (color, size, orientation)". The person's hands are visible, so maybe "a person's hands" or "a person".

Wait, the example in the problem says "main subjects (people/animals/objects)". So the main subjects here are the person (hands), the saw, the wood.

So: A person uses a hand saw to cut a large, light-brown wooden log held vertically. The person's hands grip the log and saw, pulling the blade through the material as it splits. The log is positioned outdoors near a house with a red umbrella to the right. The camera stays close and steady on the cutting action.

But need to be concise. Let's check the example output. The user's example might not be there, but the rules say concise chronological paragraph.

Let me revise:

A person uses a hand saw to cut a large, light-brown wooden piece vertically. Their hands grip the wood, pulling the saw through as it splits. The scene is outdoors near a house with a red umbrella to the right, featuring a wooden door and flower basket. The camera remains fixed, closely focused on the hands and the cutting action.

Wait, "fixed" or "steady"? Rule d: "conclude with camera perspective and movement (e.g., top-down, pan left, slight shake)." Here, the camera is steady, no movement. So "stays steady" or "remains static".

Also, "light-brown wooden piece" – the wood in the video is light brown, maybe a log or a board. The video shows it's being cut, so it's a log.

Check the motion: starting to cut, saw moving through, wood splitting.

Now, make it concise. Let's try:

A person uses a hand saw to cut a large light-brown wooden log vertically, their hands gripping the log and saw while pulling the blade through as it splits. The scene occurs outdoors near a house with a red umbrella to the right, visible behind the log. The camera remains close and steady on the cutting action.

Yes, that's chronological, describes motion (cutting, sawing through, splitting), appearance (light-brown log, person's hands), spatial (umbrella to the right, house behind), camera (close, steady).

Check rule e: background minimal unless essential. The house and umbrella are part of the background but essential for context (outdoor setting). So okay.

Rule g: exclude text, named characters. The logo on the cap is not text recognition? Rule f says "Exclude text recognition", so the logo is not to be mentioned, but since the task is to not include text, just describe. So the cap is a white cap, but maybe just "a person" without details.

Wait, rule b: "Briefly describe their

A person's hand is carving wood with a knife; the wood piece is being cut, and the knife moves precisely through the material, indicating solid-object interaction.

The background (house, windows, red umbrella) remains static throughout the frames, with no shifting or environmental motion (e.g., wind, smoke). No fluid or gaseous elements dominate.


A large crowd of people stands in a line on a gravel surface, each holding numerous light blue, white, and silver balloons. The group releases the balloons simultaneously, causing them to ascend rapidly into the overcast sky. As the balloons rise, the crowd disperses slightly, with individuals moving backward. The camera pans slightly to the right, tracking the upward motion of the balloons while remaining at eye level with the crowd. Background elements include utility poles and distant trees, but focus remains on the balloons and people.

Discrete balloons (solid objects) rise vertically due to buoyancy, with each balloon exhibiting independent motion caused by physical forces.

Background elements (ground, poles, trees) remain static with no uniform shifting; no dominant fluid or environmental motion (fire, water, smoke, wind) observed.


A person wearing a black shirt, khaki pants, gloves, and a light hat uses a green hedge trimmer to cut dense green foliage, moving left and right along a hedge; the camera follows their motion with slight shifts, maintaining focus on their actions against the backdrop of thick vegetation.

A person (wearing black shirt, khaki pants, gloves, and hat) is actively moving a hedge trimmer to cut foliage. The tool and person's body exhibit controlled, discrete motion as they trim the bushes.

The background consists of static bushes with minimal swaying (no fire, water, smoke, or wind motion dominating the scene). Background elements show no uniform shifting, indicating no environmental fluid motion.


A person in a white lab coat with green straps works at a wooden table with black materials and yellow tools. Close-up shows hands applying adhesive to a black fabric using a small bottle, then smoothing a brown sheet over the material, pulling it back to reveal the black layer beneath. The camera shifts from a medium shot to tight close-ups of the hands and materials, capturing precise handling.

The person's hands are actively manipulating black fabric and cardboard, moving the fabric in a deliberate manner (e.g., folding, positioning) which is characteristic of discrete object physics.

The background (walls, furniture) remains static with no shifting or environmental motion (fire, water, smoke, wind) observed.


RAW CAPTION: Got it, let's tackle this captioning task. First, I need to describe the video chronologically, focusing on the main subjects which are the people in the gym. Let's look at the frames.

In the first frame, there are multiple people on a gym floor. They seem to be moving around, maybe playing a game. The background has bleachers, but we need minimal background. Let's note their actions: some are running, others walking. The colors: various shirts—blue, white, pink, orange. Number: many people, maybe 20+? Wait, the rule says briefly describe appearance and number. So "multiple people in various colored athletic wear (e.g., blue, white, pink, orange shirts)".

Chronological order: the first frame shows them in motion. Then, over time, they keep moving—maybe passing a ball? Wait, in frame 0, there's a person in blue holding a ball (maybe a basketball). Then frame 1: the person in blue is moving, others are running. Frame 2: more movement, people are running around. Frame 3: they're still moving, maybe a different direction. Frame 4: people continuing to move, perhaps shifting positions. Frame 5: same gym, people moving, maybe the game is ongoing.

Spatial relationships: in front of, to the left, etc. For example, the person in blue is moving towards the center, others around. But need to keep it concise.

Camera perspective: the video starts with a wide shot of the gym, and the camera seems to pan across the court, maybe tracking the movement. The caption should mention camera movement. Looking at the frames, the camera is panning left, as the action moves from right to left over the frames.

Now, structure:

Start with the setting (gym), main subjects (multiple people in various colored athletic wear), their actions (running, moving, likely a game), then camera.

Check rules: a) motion and behavior chronological. So sequence: people begin moving in the gym, some running, others walking, passing a ball? Wait, in the first frame, there's a person with a ball (maybe basketball). Let's see—frame 0: person in blue holds ball, others around. Frame 1: blue person moves ball, others run. So maybe passing or dribbling.

But need concise. Let's outline:

At the beginning, multiple people in various colored shirts (blue, white, pink, orange) are moving across a gym floor; some run towards the center while others walk, with one individual in blue holding a ball. Over the sequence, they continuously move, shifting positions as the camera pans left to follow their motion.

Wait, but need to check number—say "multiple people" (since exact count isn't obvious). Appearance: "various colored athletic wear (blue, white, pink, orange shirts)". Motion: "running, walking, and moving across the gym floor".

Background: minimal, so mention "gymnasium with wooden flooring and bleachers" but keep minimal. Rule e says minimal unless essential. Since the bleachers are in the background, maybe just "gymnasium setting" but maybe not necessary. Wait, the video is in a gym, so the background is gym, but focus on motion.

Wait, the output should be a paragraph. Let's draft:

In a gymnasium, multiple people wearing various colored athletic shirts (blue, white, pink, orange) move across the wooden floor; some run while others walk, with one individual in blue holding a ball and shifting positions. As the video progresses, the group continues to move dynamically, with the camera panning left to follow their activity.

Check if chronological: "at the beginning... then over the sequence...". Wait, the frames are sequential, so start from the initial movement and describe the progression.

Alternative:

A group of people in colorful athletic wear (blue, white, pink, orange) are actively moving across a gymnasium floor; initially, some run toward the center while others walk, with a person in blue holding a ball. Throughout the sequence, they shift positions, continuing to move as the camera pans left, capturing the dynamic motion in the open gym space.

Check rules: a) chronological order—yes, initial actions then progression. b) appearance and number: "multiple people in colorful athletic wear (blue, white, pink, orange)"—briefly. c) spatial: "some run toward the center" (spatial relationship). d) camera: "camera pans left". e) background: minimal, just gym floor, no mention of bleachers unless essential. Maybe "gymnasium floor" is enough. f) no text, names—good.

Wait, in the first frame, the person in blue is holding a ball (maybe a basketball), but

Discrete human subjects are actively moving—running, positioning, and interacting in what appears to be a sports game (likely volleyball or basketball), with clear locomotion and potential collisions.

The gym background (wooden floors, bleachers, walls) shows no significant shifting or environmental fluid motion (no fire, water, smoke, or wind effects).


A person in a black shirt holds a power sander above a dark wooden board mounted on a stand; they rotate the sander to display its circular sanding pad and base, then position the sander to the right of the board. The board has a visible plywood edge, and a black box sits on the left. The camera remains stationary in a top-down view.

A person manipulates a solid cylindrical object (likely a camera lens), rotating and adjusting it with their hands. The object's motion is explicit, driven by physical interaction (manual rotation, positioning).

The background (plain wall and static table) shows no uniform shifting or fluid motion (no fire, water, smoke, wind), indicating no ambient environmental or camera-induced background motion.


RAW CAPTION: Got it, let's break this down. The video shows a classroom setting with blue chairs. There are a few people: a person in dark clothing standing, holding a camera or device, facing a seated person in a white shirt. Another person in dark clothing is seated, maybe taking a photo. The camera is positioned behind a wooden desk, looking towards the front. First, the person standing is holding something up, possibly filming or taking pictures. Then, another person's arm is visible holding a phone, maybe also recording. The background has a bulletin board with papers. The main actions are the standing person interacting with the seated person, others taking photos. Camera is static, low angle, maybe from a student's perspective. Need to mention motions: standing person adjusting or filming, seated people, camera position.

Wait, the rules say chronological order. Let's see the frames: frame 0 has the person standing, frame 1 same, frame 2 the standing person is holding up a device, frame 3 same, frame 4 the standing person is still holding, frame 5 maybe the person in front is moving slightly. So the main motion is the standing person (dark clothing) holding a device (like a phone) towards the seated person in white shirt. Another person (dark clothing) seated, maybe taking a photo with their phone. The camera is from behind a desk, looking at the scene.

Need to list subjects: 1. Standing person (dark jacket, holding device, facing seated person). 2. Seated person in white shirt (facing standing person). 3. Another seated person (dark clothing, back to camera, maybe taking photo). Also, a hand holding a phone (blue chair, arm visible). The camera is static, positioned behind a wooden desk, looking at the group.

Chronological: The standing person is holding a device (probably recording or taking picture) towards the seated person in white. The seated person in white is looking towards the standing person. Another person (dark clothing) is seated, and their hand is visible holding a phone, possibly taking a photo. The camera is fixed, low angle, from behind a desk, capturing the front of the classroom.

Check rules: focus on motion. So standing person moves slightly, maybe adjusting device. Seated people are stationary except for possible slight movements. Camera is static. Background: bulletin board, blue chairs. But background minimal unless essential. So describe the main subjects' actions.

Let's draft:

In a classroom with blue chairs, a person in dark clothing stands holding a device, facing a seated person in a white shirt; another seated person in dark clothing takes a photo with a phone, their arm visible. The standing person adjusts their position and device orientation while interacting with the seated individual. The camera remains static, positioned behind a wooden desk, capturing the scene from a low angle.

Wait, check the frames: first frame, standing person is holding device. Second frame, same. Third frame, maybe slight movement. Fourth frame, same. Fifth frame, maybe the person in front (seated) moves? The captions should be chronological. So the standing person (dark) holds device towards seated person (white), another seated person (dark) is taking photo. The camera is behind a desk, looking at them.

Also, need to mention number of subjects. There are at least 3 people: standing, seated white shirt, seated dark. Plus the arm holding phone (so maybe a fourth person, but only arm visible).

Check rule: "Focus primarily on the motion and behavior of main subjects (people/animals/objects) in chronological order."

So chronological: The standing person (dark clothing) holds a device (e.g., camera) towards the seated person in a white shirt. A second seated person (dark clothing) holds a phone, positioned to take a photo. The standing person adjusts the device, maintaining orientation toward the seated individual. The camera remains fixed at a low angle, behind a wooden desk, observing the group.

Also, mention appearance: dark clothing, white shirt, blue chairs.

Wait, the output must be concise. Let's make it shorter.

A person in dark clothing stands holding a device, facing a seated person in a white shirt; another seated person in dark clothing takes a photo with a phone. The standing individual adjusts their device's position. The camera stays static, positioned behind a wooden desk, capturing the scene from a low angle.

Check rules: exclude text recognition, named characters. So no names. Mention spatial: standing in front of seated person? Yes, standing person is in front of the seated person? No, standing person is behind the seated person? Wait, in a classroom, the seated person is in front, standing person is behind? Wait, the video: the camera is from behind a desk, looking towards the front. So the standing person is near the front, seated people

Two individuals in the background exhibit localized motion (e.g., gesturing, subtle body shifts) consistent with human locomotion and interaction.

Background elements (walls, posters, blue chairs) show no uniform shifting; no fire, water, or wind-driven motion present.


A person in a turquoise shirt with a pink logo and green cap crouches on grass, using a machete to cut open a coconut. They hold the coconut with one hand while slicing it, causing pieces to fall onto the grass; other whole coconuts and a coiled rope lie nearby. The camera remains stationary, capturing the action from a slightly elevated angle.

Discrete solid objects include the person (using a machete), the coconut being cut, and the machete itself. These objects exhibit motion due to manual manipulation (e.g., cutting the coconut, handling the machete).

The background consists of static grass and rope elements with no significant shifting or fluid motion (e.g., wind, water, fire). No ambient environmental phenomena dominate the scene.


A person wearing a white shirt and dark pants moves across a dimly lit room with a bed and dresser. They walk toward the bed, bend at the waist, and then turn to walk back toward the dresser. The camera remains stationary with slight motion blur.

A person is moving across the room, stepping on a rug, walking towards the dresser, and engaging in locomotion-based motion. The movement is solid and distinct.

The background elements (bed, dresser, floor) show no uniform shifting or fluid motion. No fire, water, smoke, or wind effects are present.


A man in a gray and orange jacket and light blue jeans walks toward a child in blue ice skates holding a stick on a dark ice rink. A child in teal and another in orange join, skating toward a goal net while the man follows. The camera slightly follows the movement of the group.

Multiple distinct solid objects (an adult and three children) are moving on a paved surface. Their motion is due to locomotion (skating/running) and directional changes, with clear bounding box tracking of each individual.

The background elements (fence, trees, houses) remain fixed and show no uniform shifting or environmental fluid motion (fire, water, smoke, wind). The scene is calm with static natural elements.


A hand places a white rectangular tile onto a textured adhesive surface, aligning it with an adjacent tile. The hand adjusts the tile's position and then places a second tile to the right, maintaining even spacing. The camera remains stationary, focusing on the tile placement process.

A gloved hand is moving a tile (solid object) and using a tool to smooth adhesive; the hand and tile are the discrete objects in motion.

The background (grooved wall and countertop) is stationary; no fluid or environmental motion (fire, water, wind) present.


A person wearing a white shirt, red shorts, and black athletic shoes lies on a green field marked with white yard lines. They hold a resistance band, lying on their back, moving their legs apart and then together in a stretching motion. The camera maintains a top-down perspective throughout, capturing the full body movement without shifting position.

A person wearing red shorts and a white shirt is performing leg exercises on the field. Their legs move rhythmically up and down in a controlled manner, indicating deliberate physical exertion (likely using a resistance band).

The background consists of a static football field with clear white yard lines. There is no shifting background, fire, water, smoke, or wind-induced motion; the field remains uniformly still throughout the clip.


A man in a dark shirt with red stripes and a dark cap pours a yellowish liquid from a tall clear container into a white disposable cup held in his other hand. He stands before a red tray filled with stacked white cups and metal containers, with spectators seated in the background. The camera remains stationary, focusing on the pouring motion.

A person is actively pouring liquid from a pitcher into a cup; the pitcher and cup are discrete objects undergoing motion due to manual pouring.

Background contains static elements (people, grass) with no uniform shifting; liquid pouring is controlled by a human action, not ambient environmental fluid motion.


A baby in a light purple onesie with a colorful graphic lies on a patterned blanket, initially with arms raised, then moving hands downward and shifting body position. The camera remains in a top-down view with slight movement.

Baby (discrete solid object) exhibits localized movements: arm adjustments, leg movements, and head repositioning. Motion is consistent with natural infant motor activity.

No shifting background or fluid motion detected. Background (patterned blanket) remains static throughout the sequence with no environmental elements (fire, water, wind) present.


A person wearing white shoes steps onto a brown tiled step with a metal handrail positioned to the left. The individual's feet move upward on the step, transitioning from one foot to both feet positioned on the step. The camera maintains a close-up view focused on the feet and the step.

A person's legs (wearing white shoes) and a white cane are visible, moving by stepping down the stairs.

The background (stairs) is static. No fluid or environmental motion (fire, water, smoke, wind) is present. The transition to a gradient screen is an artificial effect and not part of the scene's motion.


RAW CAPTION: Got it, let's break this down. The video shows a person in a red shirt and black pants, wearing a helmet and protective gear, like a catcher. They're in a crouched position on a green mat. Then they stand up and throw a ball. Wait, the first frame: the person is crouched, then in the next frames, they move forward, and there's another person in red in the background. Wait, the first scene has a person in red (catcher) crouched, then they stand up and run? Wait, no. Let's check the timestamps.

Frame 0: Person in red with helmet and gear, crouched. Background has another person in red standing, and some equipment (like a table with objects, drums maybe).

Frame 1: Same person, still crouched, maybe slight movement.

Frame 2: Person stands up and moves forward, then in frame 3, they're running towards the right (since the mat is green, and the background has tents).

Wait, the video is a sequence. Let's see the actions:

- First, a person in red shirt, black pants, helmet, and protective gear (like catcher's gear) is crouched on the green mat. Then they stand up and move forward, running across the mat, and throw a ball (since in frame 4-5, they're in mid-air throwing).

Wait, the description says "a person in red shirt and black pants, wearing helmet and protective gear (catcher's gear) crouches, stands, runs, and throws."

But the other person in the background: first scene, there's a person in red standing in the distance. Then in frame 3, the camera shifts to another angle, showing a person in red (maybe the same) running on a mat.

Wait, the main subject is the person in red with gear. Let's track their motion:

Start: crouched (frame 0-1), then stands up, moves forward (frame 2), then runs and throws (frame 3-5). The camera perspective: first shot is from behind the catcher, then cuts to another angle (maybe a side view) showing the person running and throwing.

So the chronological order:

1. A person in red shirt, black pants, helmet, and protective gear is crouched on a green mat. They stand up, move forward, then run while throwing a ball.

2. Background: other people and equipment, but minimal description.

3. Camera: starts with a shot from behind the crouched person, then shifts to a side view showing the person running and throwing.

Need to be concise.

Let me structure it:

The video opens with a person in a red shirt, black pants, and helmet crouched on a green mat. They stand, run forward on the mat, and throw a ball. The scene transitions to a side view as the person moves across the mat. The camera remains steady, capturing the motion from behind then shifting to a side perspective.

Wait, check the frames:

- Frame 0: Crouched person (red, black, helmet) on green mat. Background: another red person, equipment.

- Frame 1: Crouched person, slight movement.

- Frame 2: Person stands up and moves forward (away from the camera, maybe towards the other person).

- Frame 3: Person is running on a mat, then frame 4-5: throwing the ball.

So the main subject's actions: crouch, stand, run, throw.

Camera: starts with a medium shot from behind, then cuts to a side angle (the second scene shows the person running on the mat, with a different background—tent walls, so maybe the camera angle changed).

Also, background is minimal except for the green mat and some structures.

Following the rules:

a) Motion in chronological order: crouched, stands, runs, throws.

b) Appearance: red shirt, black pants, helmet, protective gear.

c) Spatial: in front of the camera initially (crouched), then moves forward.

d) Camera: starts with a shot from behind, then shifts to a side view.

e) Background minimal: green mat, indoor setting with tents.

f) Exclude text, names.

So putting it all together:

A person in a red shirt, black pants, and helmet crouches on a green mat, then stands and runs forward, throwing a ball. The camera shifts from a behind view to a side perspective as they move across the mat.

Check if that's concise. Let's see:

- Start: crouch (main subject)

- Then: stand, run, throw.

- Camera: starts behind, shifts to side.

Yes.

Wait, the other person in the background: in the first frame, there's another person in

A person in a red shirt and black pants (with protective gear) is seen pitching a ball. The motion is a discrete throwing action with visible arm and body movement.

No fluid/environmental motion (fire, water, wind) observed. Background (backdrop, flooring) is static without uniform shifting.


RAW CAPTION: Got it, let's break this down. The video shows a group of people playing Mahjong. First, I need to list the main actions in chronological order.

At the start (0.0s), they're around the table. The woman on the left has a ponytail, black coat. The man opposite her is in a gray jacket. Then, in the next frames, the woman on the right (in black) picks up a water bottle. The table has a green surface, with tiles and a bowl.

Let's check each frame. Frame 0: all seated, hands on table. Frame 1: the woman in black (right side) picks up a water bottle. Frame 2: she drinks, others move tiles. Frame 3: someone adjusts tiles, another moves. Frame 4: tiles are being arranged, hands moving.

Need to focus on motion: people's actions. The main subjects are the four people around the table. Descriptions: colors of clothes—black coats, gray jacket, etc. Spatial: seated around the table, positions relative to each other.

Chronological order:

- Initially, the group is seated around the green Mahjong table. The woman with a ponytail (left) in black, man in gray jacket (right) interacts.
- The woman in black (top-right) picks up a water bottle and drinks.
- Then, they adjust tiles on the table, moving them around.
- The man in gray jacket and others place tiles, rearrange the setup.

Background: other people in the room, but minimal. Camera is stationary? The video seems to be a fixed shot.

Now, structure the caption:

Start with initial state, then actions step by step.

"Four people gather around a green Mahjong table; a woman with a ponytail in a black coat sits on the left, facing a man in a gray jacket on the right. A woman in black on the top-right picks up a water bottle and drinks, while others adjust tiles. They move tiles across the table, repositioning them as the game progresses. The camera remains stationary, capturing the group's actions in a medium shot."

Wait, need to check number of people: in the frames, there are four main people, plus background. But the main subjects are four.

Let me count: left side: woman with ponytail (back to camera), next to her a man in black. Top row: woman in beige (behind the two), woman in black. Right side: man in gray. So four players.

So "Four individuals surround a green Mahjong table. The person on the left, a woman with a ponytail in a black coat, engages with the table; a man in a gray jacket sits across from her. A woman in black, positioned to the top-right, lifts a water bottle to drink. Subsequently, the group rearranges Mahjong tiles, moving them across the table’s surface. The camera maintains a fixed medium shot throughout the sequence."

Check if chronological: initial seating, then drinking, then moving tiles. Yes.

Also, mention appearance: colors (black, gray, beige), but be concise.

Now, make sure to follow rules. Exclude background unless essential—here, background has other people but not essential.

Camera: fixed, no movement. So "the camera remains stationary in a medium shot."

Final check:

- Motion and behavior in order: seated, drinking, rearranging tiles.
- Appearance: mention key colors (black coat, gray jacket, beige).
- Spatial: left, right, top-right.
- Camera: fixed medium shot.

Let's draft:

"Four people are seated around a green Mahjong table; a woman with a ponytail in a black coat sits on the left, a man in a gray jacket across from her. A woman in black at the top-right picks up a water bottle and drinks. They then move Mahjong tiles across the table, repositioning them. The camera remains stationary, capturing the group in a medium shot."

Yes, that's concise. Let's see if it covers all points.

Rule a: motion in order—seated, drinking, moving tiles.

Rule b: appearance and number—four people, colors mentioned.

Rule c: spatial—left, across, top-right.

Rule d: camera—fixed medium shot.

Rule e: background minimal—no mention of others.

Rule f: no text, names.

Good.

<caption_output>Four people gather around a green Mahjong table; a woman with a ponytail in a black coat sits on the left, facing a man in a gray jacket across from her. A woman in black at the top-right picks up a water bottle and drinks. Subsequently, the group

Discrete objects include players' hands (manipulating tiles) and tiles themselves. Hands move to place, shuffle, and adjust tiles on the table, with clear physical interactions (e.g., tile placement and grasping).

The background (orange chairs, green table, and distant figures) shows no shifting or fluid motion. No fire, water, smoke, or wind is present; the scene is entirely static and indoor.


RAW CAPTION: Okay, let's tackle this video captioning task. First, I need to understand the rules thoroughly. The user wants a concise, chronological paragraph focusing on the main subjects' actions, their appearance, spatial relationships, camera perspective, and minimal background details. Also, exclude text recognition and stylistic analysis.

Looking at the video description: it starts with a black screen, then transitions to a library setting where people are doing a wide leg seated stretch. The text "Wide leg seated stretch" appears. The main subjects are people sitting on mats in a library. The caption should mention their motions chronologically.

First, the scene opens with a black screen, but the user says the first frame is 0.0 seconds. The video then shows people in the library. So the caption starts from the library scene. The main action is people performing the stretch. Need to describe their posture: seated, legs wide apart, stretching. They're on colorful mats. Number of people: multiple, but not specified exactly. Appearance: various colors, maybe some in pink, orange, etc. Spatial relationships: they're spread out on the floor in the library, some sitting with legs outstretched. Background is library with bookshelves, but minimal details.

Camera perspective: the description says it's a wide shot, probably static. The user mentioned in the rules to mention camera perspective and movement. The example given in the problem has a top-down view, but the video here is a wide shot. Wait, the user's example might have been a top-down, but the actual video here is a library scene. The user says "in front of, to the left" so maybe the camera is static, capturing the entire room.

Wait, the problem states the video starts with a black screen, then transitions to a library. The caption should start from the library scene. So first frame is the library. The text "Wide leg seated stretch" is present but according to rule f, exclude text recognition, so don't mention the text. So the caption should describe the people doing the stretch, their actions.

Chronological order: the people are seated, legs spread wide, hands touching the ground or holding their feet. Maybe some are adjusting their positions. The video shows them in the process of stretching. The camera is static, wide shot, showing multiple people in the library.

Need to mention the number of people: "multiple individuals". Their appearance: "seated on colorful mats, wearing casual clothing in various colors". Spatial relationships: "spread across the floor, some in front of others, positioned near bookshelves". Background: "library setting with bookshelves and tables" but minimal. Camera perspective: "static wide shot".

Wait, the user says to exclude background unless essential. So maybe mention the library setting briefly. The key is to focus on the motion: seated, stretching with legs wide apart.

Putting it all together:

In a library setting, multiple individuals seated on colorful mats perform a wide leg seated stretch, extending legs outward and reaching hands toward the floor, with some adjusting their posture. They are positioned across the floor, some in front of others, near bookshelves and tables. The camera maintains a static wide shot capturing the group's synchronized movements.

Check rules: chronological order (they're stretching, adjusting), appearance (colorful mats, various clothing), spatial (spread out, near bookshelves), camera (static wide shot). No text mentioned, background minimal. Should be concise.

Wait, "seated on colorful mats" - yes. "Extending legs outward" - yes. "Reaching hands toward the floor" - perhaps. Maybe "some touching the floor with hands" or "reaching for feet".

Wait, the exact action is "wide leg seated stretch", so legs wide apart, maybe hands on the floor or holding feet.

Possible caption:

In a library, several people sit on colorful mats, performing a wide leg seated stretch by extending legs outward and reaching hands toward the floor. They are spaced across the room, some seated with legs stretched wide, others adjusting positions. The camera remains static in a wide shot, capturing the group's movements against the backdrop of bookshelves and tables.

Check rules:

a) Motion and behavior in order: seated stretching, adjusting. Chronological.

b) Appearance and number: "several people", "colorful mats", "various clothing".

c) Spatial: spaced across room, some in front.

d) Camera: static wide shot.

e) Background minimal: "backdrop of bookshelves".

f) Exclude text: yes.

g) No reasoning.

Looks good. Let me make it more concise.

"In a library, multiple individuals sit on colorful mats, extending legs wide apart while reaching hands toward the floor during a seated stretch. They are positioned across the room, some adjusting their stances. The camera maintains a static wide shot of the group

Multiple people are performing a seated stretch (wide leg seated stretch) with coordinated body movements (legs, arms).

The background (bookshelves, ceiling, floor) is static and does not shift uniformly. No fire, water, smoke, or wind is present. Ambient environmental motion is not dominant.


A hand holds a stack of aged, worn currency notes against a green grid surface. The hand then moves to display a brown leather-bound book with visible stitching and damage; a finger points to the book's edge, followed by placing a white ruler against its side. The hand subsequently flips through the book's pages. The camera maintains a close-up, top-down perspective with slight movement.

A hand manipulates a dark-colored flexible object (likely leather) and a white rectangular object (possibly a tool or material), with movements indicating explicit physical interaction and force application.

The green cutting mat with grid lines and newspaper underneath remain stable; no shifting background elements or fluid/environmental motion (fire, water, smoke, wind) is observed.


A pair of adult hands manipulates green and white mahjong tiles on a green table. Initially, the hands position a stack of tiles to the left of a central rack. The hands then pick up individual tiles from the stack, moving them toward the rack, and place them within the rack's circular area. The background features a green table surface with additional tile stacks. The camera maintains a top-down perspective with no noticeable movement throughout the sequence.

Hands are manipulating麻将 tiles (solid, distinct objects) by placing and adjusting them on the table, indicating deliberate physical movement.

The green table surface and surrounding tiles show no uniform shifting or fluid motion; no fire, water, smoke, or wind is present.


A woman with long dark hair wearing a light-colored top drives a car, then a man in a camouflage jacket appears in the passenger seat to her left; both remain seated, and the camera maintains a steady interior perspective.

discrete_object_physics | ambient_environmental | camera_motion | ego_motion | static

Briefly describe what discrete, solid objects are moving.

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


A man in a purple shirt and light-colored shorts sits on a wooden stool, polishing a blue shoe with a cloth; his hands move the cloth over the shoe's surface as the camera gradually zooms in, maintaining a slight shake, with minimal background details visible.

A seated person actively moves hands and a tool while manipulating materials on a small table, showing controlled, deliberate motion consistent with manual labor.

No shifting background elements or fluid/environmental motion (fire, water, wind, smoke) detected. Wall and ground remain static throughout the frame.


A person in a green striped shirt holds a light brown wooden board, rotating it to display its surface while using a black sander tool. The individual adjusts the board’s angle and position, moving it slightly in front of themselves. The camera maintains a close-up perspective with minimal movement, focusing on the person and the board.

The person (a solid object) is gesturing and moving the wooden plank, which is a discrete object under their control.

No shifting background or fluid/environmental motion (fire, water, wind) observed. Background elements (workshop tools, walls) are stationary.


Three individuals interact in a grassy park area. A person in a black and white striped shirt stands to the left, facing the center. A person in a black shirt with a logo is positioned centrally, while a person in a blue shirt holds a yellow sari draped over them. The blue-shirted individual adjusts the sari, pulling it toward the center person, who turns their body to accommodate it. The striped-shirt person gestures with their hand as the sari is repositioned. The scene occurs in a static outdoor setting with minimal background detail visible.

Three people are moving: the individual in the striped shirt (minimal motion, hand gestures), the person in the sari (dynamic motion covering/uncovering head, adjusting fabric), and the person in blue (circulating around the group). All motions are due to explicit human locomotion and actions.

The background consists of static grass and trees with no uniform shifting or environmental motion (fire, water, smoke, wind). No fluid or gaseous elements dominate the scene.


A person wearing a straw hat, white T-shirt, and gloves picks up a dark bottle from a wooden stand to their left, moves to center, and raises it. Camera remains static.

A person wearing a cowboy hat moves their arms and manipulates a small object (likely a toy or container), exhibiting deliberate physical motion.

Background elements (walls, poles, desk objects) show no uniform shifting or fluid motion; no fire, water, or wind effects observed.


A man wearing a green cap, brown jacket, and blue jeans stands over a pile of split logs on a concrete driveway, swinging an axe downward to chop wood. He then bends forward to adjust a log positioned on the ground. The scene includes a silver truck and a trailer in the background, with a brick building nearby. The camera remains stationary, capturing the action from a consistent eye-level perspective.

A person (wearing brown shirt and blue jeans) is swinging an axe to split wood; the wood pieces move due to impact and splitting.

Background elements (house, vehicles) are stationary with no fluid or wind-driven motion. No fire, water, or smoke observed.


A hand with pink-painted nails uses a black tool to create dots on a geometrically patterned wooden piece. Then, a hand with a paintbrush applies yellow watered-down paint to a brown-patterned pineapple-shaped wooden piece with a green leaf attached, positioned on a light wooden surface. The camera shifts from a close-up of the tool to a top-down view of the painting process.

Hands holding tools (dotting tool, brush) and the brush itself are moving to apply paint to patterned objects (tile and pineapple-shaped piece), with clear physical interactions (painting).

Background elements (table, work surface) remain static with no uniform shifting; no fire, water, smoke, or wind evident.


A male athlete in a blue and white uniform runs on the indoor track toward a yellow high jump bar. He leaps over the bar, arches his body, and lands on a blue mat, rolling forward and coming to rest. Spectators observe from the sidelines; the camera remains stationary, capturing the full sequence of motion.

The main object is a gymnast (blue uniform) running, jumping off the springboard, performing a vault, and landing on the mat. The gymnast is the primary moving object. Other objects include spectators and coaches, but their motion is minimal and secondary.

The background walls and floor are stable with no shifting. There is no fire, water, smoke, or wind visible.


RAW CAPTION: Got it, let's tackle this. The video starts with a man in a white shirt and dark shorts standing on a blue mat. He bends down, then moves to a knee position. The text "Valslide Mountain Climbers" is there, but we exclude text recognition. So the main action: he stands, then kneels. Describe the motion chronologically.

First frame: he's standing. Then he crouches, places hands on the mat, gets into a kneeling position. The background has a wall, mirror, poster, but minimal. Camera is fixed, no movement mentioned. So the caption should be about his actions: starts standing, bends, places hands on mat, knees down.

Check rules: focus on motion, chronological. Appearance: white shirt, dark shorts, sneakers. Spatial: on blue mat, in front of a brick wall with mirror and poster. But background minimal unless essential. The mirror is there, but maybe not essential. So maybe just say "on a blue mat in a room with a brick wall and mirror".

Wait, rule f: exclude text recognition. So ignore the text. Now, the sequence: he starts standing, then lowers his body, placing hands on the mat, moving to a kneeling position. So "A man in a white shirt and dark shorts stands on a blue mat, then bends forward, placing his hands on the mat and moving to a kneeling position with his knees on the mat."

Check if that's chronological. Yes. Background: minimal, so maybe "in a room with a brick wall and a mirror" but rule e says minimal unless essential. The mirror might be essential to show reflection, but maybe not. Let's see. The main subject is the man's movement. So focus on his actions.

Camera perspective: the video shows him from a fixed angle, no movement mentioned. So "captured from a fixed perspective."

Putting it all together: "A man wearing a white shirt, dark shorts, and sneakers stands on a blue mat, then bends forward to place his hands on the mat and moves into a kneeling position. The camera remains stationary, capturing the motion in a room with a brick wall and mirror."

Wait, rule g says no reasoning, so just the caption. Let's check the rules again. a) motion and behavior chronological. So:

Starts standing. Then bends (crouches), places hands on mat, moves to kneeling. So the caption: "A man in a white shirt and dark shorts stands on a blue mat. He bends forward, placing his hands on the mat and lowering his body to a kneeling position. The camera remains fixed, capturing his movement in an indoor space with a brick wall and mirror."

Check if all rules: b) appearance (white shirt, dark shorts), c) spatial (on blue mat), d) camera fixed. e) background minimal (brick wall, mirror). f) no text. g) no reasoning.

Yes. Now, make it concise. Maybe: "A man in a white shirt and dark shorts stands on a blue mat. He bends forward, places his hands on the mat, and kneels down. The camera remains stationary, capturing his movement in a room with a brick wall and mirror."

Yes. Let's confirm the order: standing → bending → placing hands → kneeling. Correct. The background elements are minimal but necessary for context? The problem says "minimal unless essential for understanding motion". The mirror might not be essential, but maybe it's part of the room. Alternatively, maybe just mention the room but not specifics. Hmm. The original video description has the wall with a mirror and poster, but maybe we can say "in an indoor space with a brick wall".

Wait, the problem says "background descriptions minimal unless essential". So if the mirror is not essential for the motion (the man's movement is on the mat, not related to the mirror), then maybe omit. So maybe "in an indoor space with a brick wall".

Wait, the video shows the man moving on the mat, so the mat is on the floor. The wall is behind him. So background: brick wall. Maybe that's enough.

So revised: "A man in a white shirt, dark shorts, and sneakers stands on a blue mat. He bends forward, places his hands on the mat, and lowers his body to a kneeling position. The camera remains stationary, capturing his movement in a room with a brick wall."

Check if the actions are chronological: standing → bending → placing hands → kneeling. Yes.

Now, the problem says "concise", so maybe combine the actions. "A man in a white shirt and dark shorts stands on a blue mat, then bends forward, places his hands on the mat, and kneels down. The camera remains fixed in an indoor space with a brick wall."

Yes. Let's make sure it's concise. Avoid repetition. So:

"A man in

A person in a white shirt and dark shorts is moving: bending, kneeling, and extending limbs to interact with the floor and wall-mounted equipment.

The background (walls, floor, poster) shows no uniform shifting or fluid/environmental motion (no fire, water, smoke, wind). Static elements remain consistent across frames.


A man in a black kilt, white shirt, and dark vest stands on a grassy cemetery plot with gravestones, playing bagpipes; the scene darkens to black.

The person (playing bagpipes) exhibits minimal movement, likely due to natural body motion while playing, which is a discrete object's explicit physical motion.

The background (gravestones, trees) shows no significant shifting or fluid motion; ambient elements like minor wind sway are negligible and not dominant.


A pair of hands manipulates two yellow pencils within a white electrical box, using a small tool to adjust their position. One pencil is removed, twisted, and reinserted into the box. The camera maintains a top-down perspective, focusing closely on the hands' actions against a blue surface.

Two hands manipulate a yellow pencil and a small metallic object (e.g., paper clip), performing discrete physical interactions (grasping, twisting, positioning).

Background elements (blue surface, 'HICON' text) are stationary, with no fluid or gaseous motion (fire, water, smoke) observed. Ambient environmental motion is absent.


A person wearing a dark jacket, brown shirt, and blue jeans stands in a doorway, then moves backward to close the white double doors, obscuring the hallway with a patterned floor and yellow walls behind them. The camera remains stationary, focused on the doorway throughout.

The person is walking away from the camera, and the doors are closing. Both are discrete solid objects moving due to locomotion and mechanical action.

The background consists of static walls and a room, showing no shifting or environmental motion (fire, water, smoke, wind).
