A person with long blonde hair and a white top raises their right hand, moving it from their cheek toward their forehead, then lowers the hand and smiles. The camera maintains a close-up static perspective throughout.

A single person (woman) is moving her hand in discrete motions across her face, covering and uncovering her eyes and shifting across her cheekbones. The hand's motion is clearly a solid object's physical movement.

The background is a static solid orange color with no shifting, environmental elements (fire, water, smoke, or wind), or fluid motion. All background elements are uniformly still.


RAW CAPTION: Got it, let's tackle this captioning task. First, I need to describe the video chronologically. The video starts with a top-down view of a large bowl filled with a salad. The salad has chickpeas, corn, cherry tomatoes, and fresh greens. Then, a pair of hands with metal tongs enters the frame. The hands start tossing the salad, mixing the ingredients. The tongs are used to lift and turn the salad, making sure everything is combined. The hands are active, moving the tongs in a circular motion. The background is a wooden surface, but I need to keep that minimal.

Looking at the rules: focus on motion, chronological order. So the sequence is: bowl with salad, hands with tongs enter, start tossing, mix ingredients. Mention the appearance of the hands (maybe they're wearing a watch or a bracelet? Wait, in the video description, the left hand has a watch and a bracelet, right? Wait, the user provided the video frames: in frame 0, hands are there, one has a watch, another has a ring. Let's check: "Hands holding metal tongs mix a salad of chickpeas, corn, cherry tomatoes, and leafy greens. The hands move the tongs to stir and combine the ingredients, with the salad shifting in the bowl."

Wait, the key points: main subjects are hands and tongs. Motion is tossing the salad. Appearance: tongs are metal, hands have accessories (but maybe just mention hands with tongs, not too detailed). Spatial: hands are in front of the bowl. Camera is top-down.

Let me structure the caption:

Start with the initial state: a large bowl of salad (describe ingredients briefly: chickpeas, corn, tomatoes, greens). Then, hands holding tongs enter and begin mixing. The hands move the tongs to toss and combine the ingredients. The salad ingredients shift as they're mixed. Camera perspective is top-down, no movement (since it's top-down view throughout).

So, chronological paragraph:

The video opens with a top-down view of a large bowl filled with a salad containing chickpeas, corn, cherry tomatoes, and leafy greens. A pair of hands enters the frame, holding metal tongs, and begins tossing the salad by lifting and turning the ingredients. The hands repeatedly move the tongs in a circular motion, mixing the components together as the salad shifts within the bowl. The camera remains stationary in a top-down position, capturing the mixing action against a dark wooden background.

Wait, but need to keep it concise. Let's check the rules: "concise, chronological paragraph". So maybe shorten:

A top-down view shows a large bowl of salad with chickpeas, corn, cherry tomatoes, and leafy greens. Hands holding metal tongs enter, mixing the salad by lifting and turning ingredients in a circular motion. The hands continue tossing, combining all components within the bowl, while the camera stays fixed above.

Wait, need to mention appearance of hands: in the video, the hands have a watch on the left wrist (from frame 0: "left hand has a watch and a colorful bracelet? Wait, the user's video frames: the first frame has hands with tongs, one hand has a watch (left hand), the other has a ring (right hand). But maybe just say "hands" without specific accessories unless necessary. The rules say "briefly describe their appearance and number (color, size, orientation)"—so hands are human, two of them, using tongs.

Let me check the rules again: "Focus primarily on the motion and behavior of main subjects (people/animals/objects) in chronological order." So main subjects are hands and tongs. Motion: hands hold tongs, mix salad.

So putting it all:

The video begins with a top-down view of a large bowl containing a salad of chickpeas, corn, cherry tomatoes, and leafy greens. Two hands, one with a watch and the other with a ring, enter the frame holding metal tongs and start tossing the salad. The hands move the tongs in a circular motion, lifting and turning the ingredients to mix them thoroughly. The salad ingredients shift within the bowl as the mixing continues. The camera remains stationary in a top-down perspective throughout the sequence.

Wait, but "briefly describe their appearance"—maybe "two hands holding metal tongs" instead of specific accessories. Let's see. The user's example in the problem statement doesn't have specific accessory details, but the video frames might show them. But the rules say "briefly", so maybe "two hands holding metal tongs".

Revised:

The video starts with a top-down view of a large bowl filled with a salad of chickpeas, corn, cherry tomatoes, and leafy greens. Two hands holding metal tongs enter the frame and

Two forks held by hands are mixing a salad containing chickpeas, corn, beans, and cilantro. The forks and the salad ingredients are moving in a coordinated manner due to the mixing action.

The background is a static wooden table with no shifting. There are no fluids or environmental factors such as wind, fire, or smoke.


RAW CAPTION: Got it, let's tackle this. First, the video shows a person using a circular saw. The first frame is "Sem as régulas auxiliares" (without auxiliary rulers), then the next frames are "Com as régulas auxiliares" (with auxiliary rulers). Wait, but the task says to exclude text recognition. So we don't mention the text. The main subject is the person using the circular saw. Let's break down the chronology.

First, the person is operating a yellow and red circular saw on a wooden piece. The saw is moving along a track or guide. Then, when using auxiliary rulers (but we can't mention the text), the saw is guided by the rulers. The motion: the person guides the saw along the wood. The saw is yellow and red, circular, with a spinning blade. The wood is on a workbench. Then, when using the rulers, the saw moves along the metal ruler (maybe a guide).

Need to describe in chronological order. First part: without auxiliary rulers, the saw is used on the wood, maybe less stable. Then with auxiliary rulers, the saw is guided by the rulers, so more controlled movement.

Wait, the video has two scenes: first without rulers (text "Sem as régulas auxiliares"), then with rulers (text "Com as régulas auxiliares"). But we can't mention the text. So the video shows the saw being used in two scenarios. But the task says focus on motion and behavior of main subjects.

Main subject: a person (hands visible) using a circular saw (yellow and red, with a silver blade) on a wooden board. The saw moves along a track or guide. In the first part, without rulers, the person holds the saw, moving it across the wood. In the second part, with rulers, the saw is guided by metal rulers (or auxiliary rulers) along a track, so the person is guiding the saw along the ruler.

Now, describe the chronological order. The video starts with the saw being used on the wood without rulers (but no text, so just the action), then transitions to using the rulers. Wait, the first frame has the text "Sem as régulas auxiliares" but we ignore that. So the first part: a person operates a yellow and red circular saw on a wooden workpiece. The saw's blade spins as it moves across the wood. Then, the scene changes to the person using the saw with auxiliary rulers, where the saw is guided along a metal ruler (or auxiliary guides), moving steadily along the track.

Wait, the user says "Exclude text recognition", so we don't mention the text. So the video's first part is a person using the circular saw on wood without auxiliary rulers, then the second part shows the same person using the saw with auxiliary rulers.

But need to describe motion: in the first part, the person's hand guides the saw, which is placed on a wooden surface, moving the saw across the wood. The saw is yellow and red, the blade is spinning. Then, in the second part, the person uses the saw with auxiliary rulers (metal bars), guiding the saw along the rulers, which provides a straighter cut.

Now, structure the caption:

A person operates a yellow and red circular saw on a wooden workpiece; the saw's blade spins as the hand guides it across the wood. Subsequently, the person uses the same saw with auxiliary metal rulers, guiding the saw along the rulers to make a straight cut.

Check rules:

a) Focus on motion: yes, describes the saw moving, hand guiding.

b) Appearance: yellow and red saw, wooden workpiece.

c) Spatial: the saw is on the wood, then guided by rulers.

d) Camera: the video seems to be a close-up shot, focusing on the saw and workpiece. Camera movement: probably steady, close-up.

e) Background minimal: the background is a workshop, but minimal.

f) Exclude text: yes.

So put it all together. Make sure it's concise, chronological.

Let's draft:

A person uses a yellow and red circular saw on a wooden board, guiding it across the surface while the blade spins. The individual then employs auxiliary metal rulers to guide the saw along a straight path, resulting in a more precise cut.

Check for chronological: first the saw without rulers, then with rulers.

Yes.

Wait, the video shows "Sem" first (without) then "Com" (with). So the order is without rulers first, then with.

So the caption should reflect that.

Final draft:

A person operates a yellow and red circular saw on a wooden workpiece, guiding it with their hand as the blade spins across the surface. Subsequently, the person uses the saw with auxiliary metal rulers, positioning the saw along the rulers to make a straight cut.

Yes, that's

The circular saw blade is spinning and the wooden piece being cut is being fed through the saw. Both are solid objects moving due to the saw's operation.

The background (workbench and wooden planks) is static; no shifting or environmental motion (fire, water, smoke, wind) is observed.


A person in a light jacket uses tongs to adjust items on a metal grill. The camera pans right to reveal a second person holding a plate and a can, then shifts focus to a table where an individual in a blue and white striped shirt stirs food in a large pan. Green bushes form the background, and the camera moves in a rightward pan across the scene.

Two individuals are moving: one uses tongs to handle meat on a grill, and another maneuvers a large pan at a table.

The green hedge and ground show no significant shifting; no dominant fire, water, or wind motion observed.


RAW CAPTION: Got it, let's tackle this. First, I need to look at the video frames. There are three people. Let's check their positions and actions.

First frame: three individuals standing. Left person in striped shirt (green, white, blue) holding a bottle, maybe drinking. Middle in black shirt with red cap, right in black tank with skull. They're outside, maybe near a building with metal bars.

Next frames: they're moving a bit. Left person continues drinking, middle person gestures with hands, maybe talking or pointing. Right person stays mostly still. The middle person's cap is red, so that's noticeable.

Chronic order: start with them standing, then left drinks, middle gestures, right stands. Need to describe motions. Also, camera—looks like static or slight shake, no movement mentioned.

Background: minimal, just a building with metal gate, night setting. Don't need to detail unless essential. So focus on people's actions.

Now, structure: chronological. Start with initial pose, then actions. Appearance: three people, left striped shirt, middle red cap black shirt, right skull tank. Movements: left drinks, middle gestures, right stands. Camera: probably static, but check. The video seems to have a slight shake maybe? The instruction says conclude with camera perspective.

Wait, output must be concise paragraph. Let's draft:

Three individuals stand near a building with metal bars at night. The person on the left, wearing a green, white, and blue striped shirt, holds a bottle and drinks; the middle person in a black shirt and red cap gestures with their hands; the person on the right, in a black tank top with a skull design, stands still. The camera remains static with slight shake, capturing their movements as they interact.

Wait, check rules: a) motion and behavior chronologically. So first frame: they're standing. Then in next frames, left drinks, middle gestures. So sequence: standing, then left drinks, middle gestures. Also, mention appearance briefly (colors, etc.).

Let me check the frames:

Frame 0: all three standing. Left: striped shirt, holding bottle. Middle: red cap, black shirt. Right: skull tank.

Frame 1: left drinks, middle gestures (pointing?), right looks.

Frame 2: left drinks, middle gestures more, right looks.

Frame 3: left drinks, middle gestures (maybe pointing again), right same.

Frame 4: left drinks, middle gestures, right same.

Frame 5: left drinks, middle gestures, right same.

So overall: three people stand together; left drinks from bottle, middle person gestures with hands, right person remains still. Camera is static, slight shake.

Now, concise paragraph:

Three people stand outdoors at night near a building with metal bars. The individual on the left, wearing a striped shirt, drinks from a bottle; the middle person in a red cap and black shirt gestures with their hands; the person on the right, in a black tank top with a skull graphic, remains stationary. The camera captures their interactions with minimal movement, remaining mostly static with a slight shake.

Check rules: no text, no names. Mention spatial (left, middle, right). Motions chronological (standing, then drinking, gesturing, standing still). Camera: static, slight shake. Background minimal (just building with metal bars, night). Seems okay.

Wait, rules say "briefly describe their appearance and number (color, size, orientation)". So appearance: left striped (colors green/white/blue), middle red cap black shirt, right black tank skull. Number is three. Orientation: standing in a line, left, middle, right.

So revise:

Three individuals stand near a building with metal bars at night. The person on the left wears a green, white, and blue striped shirt and drinks from a bottle; the middle person, in a red cap and black shirt, gestures with their hands; the person on the right wears a black tank top with a skull graphic and remains still. The camera remains static with slight movement throughout the sequence.

Check if "slight movement" is correct. The instruction says "conclude with camera perspective and movement". In the frames, the video might have a slight shake, so "slight shake" is better.

Also, "chronological order"—start with standing, then left drinks, middle gestures. So:

Three people stand together outdoors at night. The left individual, in a striped shirt, drinks from a bottle; the middle person, wearing a red cap and black shirt, gestures with their hands; the right person, in a black skull tank top, remains stationary. The camera stays static with a slight shake, capturing their interactions.

Yes, that's concise. Let's make sure it's all in one paragraph.

Final version:

<caption_output>Three individuals stand near a building with metal bars at

Three people (discrete solid objects) are moving: the person in the center makes hand gestures, the person on the left holds an object to their face, and the person on the right shifts slightly.

No shifting backgrounds; no dominant ambient environmental motion (fire, water, smoke, wind) observed. Ambient lighting flickering is minimal and not fluid.


A person wearing a gray shirt with red sleeves and black pants sits on a stool, playing an orange electric bass guitar with a white pickguard and silver knobs. Their right hand strums the strings while the left hand frets notes along the neck. The camera remains stationary, capturing a medium shot from a slight angle with minimal background elements visible.

The person's hands and fingers are moving to play the instrument, representing discrete solid object motion (human limbs interacting with the instrument).

The background (walls, floor) remains static with no uniform shifting or fluid motion (no fire, water, smoke, or wind evident).


A hand with a green-handled brush applies orange and yellow paint to a circular object featuring black details, moving the brush across its surface. A second hand enters from the right, adjusting the object while the first hand continues painting. The circular object rests on a dark surface, with a book partially visible to the right. The camera maintains a top-down, stationary perspective.

Hands and paintbrush are moving to apply pigment to the canvas. Solid objects exhibiting explicit physical motion from the artist's deliberate actions.

Background elements (dark surface, white product box) are stationary with no shifting or fluid motion. No fire, water, smoke, or wind detected.


A girl in a pink shirt and black pants stands near a wooden TV stand, then walks toward a green rug with colorful Mickey Mouse-themed items. She bends down and interacts with the objects on the rug. The camera remains stationary, capturing the scene from a fixed angle.

A child (solid, distinct object) moves from a standing position near the wall to sitting on the rug, exhibiting locomotion and positional changes without visible external forces beyond self-propelled movement.

Background elements (wooden cabinet, TV, framed pictures, tiled floor) remain uniformly static throughout the clip. No fluid motion (fire, water, smoke) or wind-driven effects are observed.


Three people interact around a cluttered table with electronic components and tools. A woman in a black top holds a wooden block, shifting it across the table toward a man in a black-and-white striped shirt who gestures toward the block. A woman in a blue jacket observes from the left, maintaining her position. The man points at the block as the woman in black adjusts its position, while the woman in blue watches attentively. The background features a white wall and an electrical panel; the camera remains static throughout.

The person in the striped shirt is moving their arm (hammer) in a repetitive striking motion. The object being struck (nail or wood) shows minor movement due to impact. Other individuals are mostly static.

Static background with no shifting walls or environmental fluids. No fire, water, smoke, or wind detected.


A person with long dark hair and green eyes uses a cotton swab on their eyebrow, looking at the camera, then downward, then upward while continuing application against a glittery curtain backdrop. The camera remains in a close-up, static position.

A hand holding a cotton swab moves deliberately to apply makeup to the eyebrow, representing discrete solid object motion.

The background (shiny curtain) is static and shows no shifting or environmental motion (e.g., no fire, water, wind). No fluid or gaseous elements are present.


RAW CAPTION: Got it, let's tackle this captioning task. First, I need to go through the video frames step by step.

The first frame shows a woman in a white shirt sitting at a counter, facing a man in black who's holding glasses. There's another person in red in the background. So, main subjects here: woman, man, and maybe the background person. The woman is seated, man is standing at the counter, holding glasses.

Second frame: close-up of a woman adjusting glasses with her hand. The glasses are dark-framed, maybe black. Her face is partially visible.

Third frame: similar close-up, but the glasses are being adjusted, and a different angle maybe? Wait, the second and third frames are both close-ups of the glasses, so maybe the same woman adjusting glasses.

Fourth and fifth frames: a framed picture with three men, but the text "Eye Associates of Marinette" is there, but rule f says exclude text recognition. So I shouldn't mention the text. But the video shows a frame with a logo, so maybe the background has the logo. But rule e says minimal background unless essential. So maybe just mention the framed picture.

Now, chronological order: first scene is the woman at the counter with the man, then close-up of adjusting glasses, then the framed picture. Wait, the video sequence is:

Frame 0: woman at counter, man holding glasses, background person.

Frame 1: close-up of woman adjusting glasses (hand near glasses).

Frame 2: same close-up, maybe more of the glasses adjustment.

Frame 3: framed picture with three men, logo, but since we exclude text, maybe just "a framed photograph".

Frame 4: same as frame 3, maybe the logo is part of the frame.

Now, need to describe motion and behavior.

First, woman seated at counter, man (black shirt) standing opposite, holding glasses. Then, close-up of woman adjusting glasses with her hand. Then, the framed photo.

Spatial relationships: in the first scene, woman is seated at counter, man is standing next to her.

Camera movement: first shot is a medium shot of the scene, then cuts to close-up of the woman's face adjusting glasses, then cuts to a still frame of the framed picture.

Rules: exclude text, so no mention of "Eye Associates" or phone number. Focus on motion: the man is holding glasses, the woman is adjusting them. Then the framed picture is shown.

Let me structure:

Start with the first scene: a woman in a white shirt sits at a wooden counter, facing a man in black who holds a pair of glasses. A person in red stands in the background near a doorway. Then, the camera cuts to a close-up of a woman’s face, where a hand adjusts dark-framed glasses on her nose. Finally, the camera shows a framed photograph of three men against a neutral background.

Wait, need to check if the person in red is relevant. The first frame has a woman in white, man in black (holding glasses), another person in red in the background. So mention the background person briefly.

Then, the close-up: the woman's face, adjusting glasses. The hand is near the glasses.

Then the framed photo. But the third frame is a framed picture with three men, but the rules say exclude text, so just "a framed photograph of three people".

Now, check the rules:

a) Motion: first scene has people in a room, man holding glasses, woman sitting. Then close-up of adjusting glasses. Then a still frame of the framed photo.

b) Appearance: woman in white shirt, man in black, person in red. Dark-framed glasses.

c) Spatial: woman seated at counter, man standing next to her; background person near doorway. Close-up of face, hand adjusting glasses.

d) Camera: starts with medium shot, then close-up, then static shot of the frame.

e) Background minimal: just mention the background person briefly, the counter, doorway.

f) Exclude text: don't mention the text on the frame.

Now, let's draft:

A woman in a white shirt sits at a wooden counter facing a man in black who holds glasses; a person in red stands in the background. The camera cuts to a close-up of a woman adjusting dark-framed glasses with her hand. It then shows a framed photograph of three people against a neutral backdrop. The camera transitions from a medium shot to close-up and then to a static view.

Wait, but need to be concise. Let's make it a single paragraph.

First, describe the initial scene: woman seated at counter, man holding glasses, background person. Then, close-up of woman adjusting glasses. Then, the framed photo.

Check if "person in red" is necessary. Maybe "a person in red is visible in

Discrete objects include the man and woman at the table (interacting via hand movements), a person walking in the background, and the hand adjusting glasses in the close-up shot.

The background elements (walls, door, interior of the diner) are static and do not shift uniformly. No fire, water, smoke, or wind motion is present.


A person in a light-colored shirt holds a metallic object with multiple prongs, lifting it toward their mouth and tilting their head back; the sequence is in black and white with close-up shots focused on the action, set against a plain background.

A person is holding and manipulating multiple knives, moving them toward their mouth in a deliberate action. The knives are discrete solid objects exhibiting motion due to the person's physical manipulation.

No shifting background elements (walls, bed remain static). No fluid/environmental motion (fire, water, smoke, wind) present.


A whole pig, charred with darkened skin and skewered with metal rods, rotates on a spit over a smoldering fire, emitting smoke. As the camera pans right, several people stand in the background to the right, observing the roasting process. The pig continues spinning, with its grilled surface visible as the camera maintains a steady perspective.

A whole pig on a rotating spit (rotisserie) is the primary discrete object; it is rotating mechanically due to the rotisserie mechanism, with small movements from the camera's perspective but no other distinct solid objects exhibiting significant motion.

The background includes a stationary building with a 'P' sign; no significant shifting of background elements is observed, and there is no dominant fluid or environmental motion (e.g., fire, water, wind) driving the scene.


A person in a light gray jacket and white checkered pants crouches on a ground covered with dry leaves and scattered green plants, holding a small object in their hands while a purple bag rests nearby. They then stand and adjust the purple bag, moving slightly forward. The camera maintains a close-up perspective, following the person’s movements with minimal shift.

A person (in light clothing) is actively manipulating dry leaves and a purple bag, with discrete hand movements transferring leaves into the bag.

Background elements (dry leaves, ground) show no uniform shifting or fluid motion; no fire, water, or smoke present.


A person wearing a black shirt, denim shorts, and colorful bracelets cuts a watermelon with a knife, slicing the red-fleshed fruit with green rind into pieces and placing them onto a white plate on a brown table. The camera remains in a close-up, fixed position.

A person's hands (wearing a black shirt and denim shorts) moving to slice watermelon using a knife. The watermelon pieces are held stationary on a plate while the knife interacts with them.

Static kitchen background with no shifting walls or fluid motion (e.g., fire, water, smoke). The tabletop and countertop remain fixed throughout the clip.


A soccer player in a white jersey dribbles a yellow ball across the green field, then kicks it toward the goal. The ball flies toward the net as multiple players in red jerseys attempt to defend, while a player in a green jersey moves toward the goal. The ball enters the net, and players in red and green react. The camera follows the ball’s trajectory with a slight pan, capturing the action from a side perspective.

Discrete solid objects: soccer ball (kicked and moving toward goal), players in white/red jerseys (running, kicking, colliding), and goalkeeper (diving to save). All exhibit physical locomotion and collision dynamics.

Static background elements (advertising boards, goal net, field markings) show no uniform shifting or fluid motion (fire, water, smoke, wind). The environment is a controlled sports field with no dominant environmental phenomena.


A hand holds a transparent plastic bottle, lifting and adjusting it on the left panel. On the right panel, a hand presses and moves across a person's light brown skin. The video displays a split-screen format with static camera positioning, capturing the sequential motions of each panel.

Discrete solid objects: hands pulling up underwear (left panel) and hand touching buttocks (right panel). Motion involves physical contact and displacement of clothing/skin due to hand movement.

No fire, water, smoke, or wind present. Background elements in both panels (fabric on left, skin on right) are static with no uniform shifting or environmental fluid motion.


A person with light pants grips a steering wheel on a yellow vehicle, then adjusts seat belts inside the vehicle. The individual, now in dark shirt and jeans, steps away to reveal the vehicle’s side on sandy ground and adjusts the seat. The camera shifts from close-up to top-down, following the person’s movements around the vehicle.

A person operating a lawnmower (steering wheel manipulation, seat adjustment) and the lawnmower itself exhibit solid object motion due to human-controlled locomotion.

Static wooden surface background with no shifting elements or fluid/environmental motion (fire, water, smoke, wind) observed.


The video opens with a wide shot of an outdoor area featuring a large white platform with a circular target, surrounded by buildings and red-and-blue balloons. A person in a white shirt throws an object at the target. The camera cuts to a close-up of the target, then shifts to a medium shot of a man in a dark jacket speaking into a microphone while children run across the platform. The camera maintains a steady perspective, transitioning between wide, close, and medium angles throughout.

A ball is rolled across a white surface by a person; the ball moves due to the push and then continues rolling due to inertia and friction.

The background elements (buildings, trees) are stable with no uniform shifting. No fluid or wind motion (flags are static).


A person in a brown shirt with a green design and pearl necklace holds a small object in their hands, manipulating it before using a cloth to wipe it, while a light-colored dog rests partially in view to the right. The camera maintains a close-up, static perspective on the person’s upper body and hands.

The person's hands are moving a small object (likely a pen) through deliberate manipulations such as holding, rotating, and placing on a surface.

The background (blue wall and furniture) is static with no shifting or environmental motion (e.g., fire, water, smoke, wind).


The camera starts focused on a black plastic sheet, then pans left to reveal a pile of crumpled white papers and assorted packaged items. A hand enters the frame, lifting and shifting the papers to expose more objects, including a green tea box and other containers. The camera follows the hand's movement, maintaining a close perspective as it transitions across the scattered items.

A hand (discrete object) interacts with items (e.g., red packet, teal can, white paper), moving them across the scene through grasping and positioning.

No fire, water, smoke, or wind observed. Static background elements (black plastic sheet, white cloth) show minimal uniform shift; motion is localized to objects in the foreground.


A person wearing a plaid shirt uses two hands to press illuminated squares on a rectangular grid, causing the blue, pink, and white squares to change color with each contact. The hands move rhythmically across the grid, interacting with the squares in sequence. The camera maintains a top-down perspective, capturing the hands and grid against a plain white background.

Hands are actively pressing and moving on a digital tablet interface, showing explicit physical interaction with solid objects.

Background is static; no environmental motion (fire, water, smoke) detected. No uniform shifting of walls or ground elements.


A man in a red shirt and jeans adjusts the trunk of a large inflatable elephant with red and gray sections, featuring prominent tusks and circular eyes. Another man in a blue shirt and light pants joins him, both working on the inflatable structure. The camera pans around the elephant, capturing its size from multiple angles as the men continue their adjustments, with the background showing a grassy field and sparse trees. The camera movement includes slight pans to the left and right.

Two people (one in red, one in blue) move around the stationary inflatable elephant structure; their motion is due to walking and locomotion.

The background (trees, ground) remains static with no shifting; no fire, water, smoke, or significant wind effects observed, ruling out ambient environmental motion.


RAW CAPTION: Got it, let's break down the video. First, the video starts with a close-up of hands using a tool on a metal object, but there's blue light and sparks. Wait, the second frame is the main action: a person grinding metal on a belt sander. The hands are holding a metal piece, sparking as it's ground. The background is a brick wall. Let's check the rules.

Chronological order: The first scene is a bit unclear, but the main action is the grinding. So the main subject is the person's hands (wearing a watch, maybe) using a belt sander on metal. The metal piece is red, being ground, sparks fly. Background is brick wall. Camera is close-up, focused on hands and the grinding process. No background details except the brick wall.

So the caption should describe the hands operating the belt sander, the metal piece, the sparks, the background. Keep it concise. Let's structure it:

A pair of hands, one wearing a watch, holds a red metal object against a moving belt sander, generating bright sparks as the object is ground; the scene occurs against a brick wall background. The camera maintains a close-up view focusing on the grinding action.

Wait, the first frame is a different scene but the task is to describe the provided video, which includes those clips. Wait, the user provided video segments, so the entire video is the sequence of those frames. Let's see the frames: [0.0] is a blue light scene, but then [1.4] to [5.0] is the grinding. Wait, the problem says "the provided video", so maybe the first frame is part of it, but the main action is the grinding. But the rules say focus on main subjects. Let's check the frames:

Frame 0: close-up of hands with blue light (maybe a tool), but maybe that's the start. Frame 1-5: hands on belt sander. But the task is to generate a caption for the video as a whole.

Wait, the user's example input has the video segments from [0.0] to [5.0], so the video transitions from a blue light scene to grinding. But the caption should be chronological. Let's see:

The video begins with a close-up of hands holding a tool emitting blue light, then transitions to a person using a belt sander on a red metal object, producing sparks against a brick wall background. The camera stays focused on the hands and grinding action throughout.

But the rules say "focus primarily on motion and behavior of main subjects". The main subject in the grinding part is the hands grinding. The first part is maybe less important. Wait, the problem says "describe the provided video", so all segments. But the rules say "chronological order".

Wait, let's check the exact video provided:

[0.0] shows hands with blue light (maybe sparks? But it's blue, not the usual sparks). Then [1.4] to [5.0] is the belt sander with sparks.

Wait, perhaps the first frame is the start, then the second. Let's see:

First frame: hands with blue light (maybe grinding with a different tool), then next frame is belt sander. But the main action is the belt sander part.

Wait, the rules for caption: focus on main subjects. The main action here is grinding metal on the belt sander. So the caption should describe that sequence.

Let me check the rules again:

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

b) Describe appearance and number.

c) Spatial relationships.

d) Conclude with camera perspective.

e) Minimal background.

f) Exclude text, names, style.

So the video starts with a scene (maybe the hands holding something with blue light, but the main part is the grinding). Let's assume the video is about the grinding process. The hands (wearing a watch) hold a red metal piece against a belt sander, sparks fly. Background is brick wall. Camera is close-up.

Putting it all together:

A pair of hands, one adorned with a wristwatch, grips a red metal object against a belt sander, generating bright sparks as the object is ground; the scene unfolds against a brick wall backdrop. The camera maintains a close-up perspective, focusing on the grinding motion.

Check if it's concise, chronological. Yes. Mentioned motion (grinding), subject (hands, metal), appearance (red metal, watch), background (brick wall), camera (close-up).

<caption_output>A pair of hands, one wearing a wristwatch, holds a red metal object against a belt sander, generating bright sparks as the object is ground; the scene occurs against a brick wall background. The camera maintains a close-up perspective, focusing on the grinding action.</

Hands manipulating an angle grinder against a metal object, producing sparks through controlled contact; the grinder and metal exhibit discrete motion from physical grinding forces.

The background (brick wall and floor) is static with no shifting motion; no fluid/environmental motion (fire, water, wind) dominates. Sparks are a transient byproduct of grinding, not primary ambient motion.


Two men walk across a sunlit plaza; one wears a brown shirt and jeans holding a drink, while the other wears a dark jacket and jeans. The scene shifts to a shirtless man with a white bandana on his chest adjusting his torso, surrounded by onlookers capturing photos. The camera then cuts to a crowded narrow street where numerous people, some holding smartphones, navigate through the bustling area. The camera transitions between these scenes with minimal background detail.

Discrete solid objects: two men walking in the plaza (first segment), a shirtless man standing (second segment) and people walking in the street (third segment). All motion is due to human locomotion.

Background (buildings) is static in all segments. No ambient environmental motion (fire, water, wind) observed.


A man in a white hoodie, dark blue shorts with white stripes, and red socks stands before a maroon heavy bag mounted on a brick wall. He throws a sequence of punches toward the bag, shifting his stance and moving his arms rhythmically. Additional hanging punching bags are visible in the background. The camera remains stationary with a slight shake.

A person (wearing white hoodie, dark shorts, red shoes) is actively punching a red heavy bag, causing it to swing. The person's locomotion (stepping, pivoting) and the bag's displacement are discrete solid object motions due to physical impact.

The background (brick wall, floor, and hanging heavy bags) is static with no shifting or fluid motion. No fire, water, smoke, or wind is present.


A person wearing a white t-shirt, purple-and-white striped shorts, and gray hat plays a ukulele while seated. The camera moves slightly, shifting angles around the subject near a white cabinet and floral curtain.

A person is actively playing a guitar, with hand movements on the strings and fretboard, and slight body motion.

Background elements (cabinet, curtain, chair) are static; no environmental motion or fluid effects observed.


A person in dark clothing stands on a snowy field with a red sled, accompanied by two light-colored dogs to their right. The person begins moving forward, dragging the sled while the dogs run behind, maintaining their position to the right. The camera follows the movement, panning slightly to the right to keep the subjects in frame.

A person (in red) and sleds are pulled by dogs across the snow, showing consistent locomotion due to physical forces (pulling).

The background (trees and snow) is static; no evidence of fire, water, wind, or other fluid/environmental motion.


A man in a dark suit picks up a red folded item from a table, lifts it to hold upright, then gestures toward a white container with colorful items positioned to his right. The table also holds a book and a black case with items to his left. The camera remains stationary.

Man (a person) moves hands and body to handle a red object; red object is picked up and moved by the man.

Background (walls, window) remains static; no fluid/environmental motion (fire, water, smoke, wind) observed.


RAW CAPTION: Okay, let's tackle this video captioning task. First, I need to understand what the user is asking for. They want a concise, chronological paragraph describing the video, following specific rules.

Looking at the video frames provided, it's a person cutting a pineapple. The main subject is a person's hands using scissors to slice through the pineapple. The person is wearing jeans, as seen in the frames. The pineapple is yellow with brown spots, and the top part has the green leafy crown.

Rule a) says focus on motion and behavior in chronological order. So I need to describe the sequence: the hands start cutting the pineapple, maybe adjusting the position, continuing to cut.

Rule b) mentions appearance and number. The hands are visible, the person is wearing jeans. The pineapple is yellow with brown spots. Maybe there's another person holding the pineapple? Wait, in the frames, there's a hand holding the pineapple, so two hands: one cutting with scissors, the other holding the fruit.

Rule c) spatial relationships. The scissors are in the right hand, the left hand holds the pineapple. The background has a green cloth and some items, but keep background minimal.

Rule d) camera perspective: the camera seems to be at a close-up angle, maybe fixed, since there's no mention of movement. The video starts with the hands cutting, then continues.

Rule e) background minimal. The green cloth and some items like a box are in the background, but not necessary to detail much.

Rule f) exclude text recognition, so no mention of any labels or signs.

Putting it all together: Start with the hands cutting the pineapple, describe the action step by step, mention the appearance of the hands, the pineapple, the scissors. Note that one hand holds the pineapple, the other cuts. The camera is close-up, steady.

Check for chronological order: the video starts with the cutting motion, maybe the pineapple being held, then the scissors cutting through, maybe adjusting the position, continuing to cut.

Avoid any extra details. Keep it concise. The caption should be a paragraph, not bullet points.

Wait, the user says "concise, chronological paragraph". So the sequence should be: person holds pineapple with one hand, uses scissors to cut, continues the cutting motion.

Let me draft:

A person wearing blue jeans uses scissors to cut a yellow pineapple with brown spots. The right hand holds the scissors, while the left hand secures the fruit’s leafy top. The cutting motion progresses as the scissors slice through the pineapple’s rind, adjusting the angle slightly. The background includes a green cloth and scattered items. The camera remains stationary, close-up on the hands and pineapple.

Wait, check rules: mention spatial relationships. The left hand is securing the top, right hand cuts. The camera is stationary, close-up.

Wait, the video might show the pineapple being cut in a specific way. The frames show the scissors cutting through the pineapple, maybe separating the rind from the fruit. So the action is cutting the rind away.

Another angle: the person is removing the outer skin, slicing it off. So the motion is the scissors moving along the pineapple to remove the skin.

In the frames, it's a close-up of the hands cutting the pineapple. The first frame shows the scissors starting to cut, then moving along the side. The pineapple is held vertically, the top is held by one hand, the other hand cuts.

So the caption should mention the hands, the pineapple's color and spots, the action of cutting, the spatial arrangement of the hands, and the camera being close-up and stationary.

Avoid mentioning specific objects in the background except maybe the green cloth, but keep it minimal. The problem says "minimal unless essential for understanding motion". So maybe just mention the green cloth as part of the background.

Wait, the background has a green cloth and some items, but maybe not necessary. The main focus is on the action. The user says "background descriptions minimal unless essential for understanding motion".

So perhaps just mention the green cloth as part of the setting without details.

Putting it all together:

A person wearing blue jeans uses scissors to cut a yellow pineapple with brown spots. The left hand holds the pineapple’s leafy top while the right hand maneuvers the scissors along the fruit’s rind. The cutting motion progresses methodically, slicing through the outer layer. The camera maintains a stationary close-up perspective on the hands and pineapple against a background featuring a green cloth and scattered items.

Check rules:

- Chronological: starts with the action, then progress.
- Appearance: yellow pineapple, brown spots, blue jeans.
- Spatial: left hand holds top, right hand cuts.
- Camera: stationary close-up.
- Background minimal: green cloth mentioned briefly.

Yes, that seems to fit. Let me check the rules again.

a) Motion in order: cutting action starts, then continues. Correct.

b) Appearance

A person's hands and a knife are moving to cut a pineapple, causing the pineapple to be sliced and pieces to fall.

Background elements (box, containers, green bag) are stationary; no fluid or wind motion present.


A hand manipulates red playing cards on a beige carpet. Initially, the hand holds a face-up diamond card above a face-down card fan and a face-up heart card to the left of the fan. The hand then moves the diamond card down to place it adjacent to the heart card, followed by adjusting the face-down card fan. The camera maintains a top-down static perspective.

A hand manipulates playing cards through lifting, placement, and flipping actions.

The carpeted floor background is static with no fluid/environmental motion (fire, water, wind) or shifting patterns.


A child wearing a yellow and black shirt sits in the driver's seat, gripping the steering wheel. An adult's hands assist the child's hands on the wheel as the child turns it slightly. The vehicle moves past trees outside the car window. The camera captures the scene from the passenger seat with slight motion and a shaky perspective.

A child is actively moving their hands on the steering wheel while being held by an adult; the child's motion is discrete and driven by their own physical actions.

The background (trees and outdoor environment) shows uniform shifting motion consistent with the vehicle's movement, but no fire, water, or smoke present; thus, ambient environmental motion is absent.


A small baby wearing a white shirt, denim shorts, and pink pants pushes a colorful toy cart with a blue base, green and yellow top, and pink/red wheels across a tiled floor. The baby moves forward toward the left side of the frame, then turns slightly while continuing to push the cart, approaching a dark doorway where an adult's hand appears from the left. The camera follows the baby's movement with a slight shake.

The toddler (person) and the toy vehicle are moving. The toddler pushes the toy, causing it to roll forward due to physical contact and locomotion.

The background (wall, tiled floor, and doorway) shows no uniform shifting or fluid motion. No fire, water, smoke, or wind is present.


A person wearing a black jacket over a white shirt sits on a wooden bench against a stone wall, holding a pink and white handheld device. They manipulate the device with both hands, rotating and adjusting its position. The camera remains stationary in a close-up perspective focusing on the hands and device.

A person is interacting with a pink mobile phone, exhibiting discrete hand movements (e.g., tapping, holding) that are clearly solid object motions.

The stone wall background is static and uniform throughout the clip, showing no shifting or environmental fluid motion (fire, water, wind).


A hand grips a yellow and black power drill, holding it steady with the drill bit extended forward. The drill then begins penetrating a wooden surface, creating a small hole as it operates. The camera maintains a close-up perspective throughout, focusing on the drill's motion against the wood.

A yellow power drill is actively drilling into a wooden block, with discrete movement of the drill bit penetrating the wood due to physical force application.

No shifting background elements or fluid/environmental motion (fire, water, wind) observed; background remains static (workbench) during drilling sequence.


A group of people in a swimming pool hold hands in a circle as a man in a blue cap and dark shirt stands on the pool deck, then jumps into the water, causing a splash. The camera remains static, capturing the scene from a fixed angle.

Discrete solid objects include swimmers in the pool (moving by locomotion/swimming) and an instructor on the deck (gesturing and moving slightly). All motions are trackable with bounding boxes.

The background elements (fence, buildings, trees) show no uniform shifting, and water movement is primarily due to swimmer activity rather than fluid dynamics. No fire, smoke, or significant wind-driven motion is present.


A man in a white tank top and black shorts lies prone on a bench press, gripping a heavy barbell loaded with large weights. A second man in a purple shirt and black pants stands behind him, hands on the barbell, assisting. The lifter presses the barbell upward, the spotter stabilizes it, then lowers the barbell back to the bench as the spotter steps back slightly. The camera remains static throughout, capturing the sequence from a fixed angle.

A person on a bench press lifts a barbell vertically; a standing person assists by holding the barbell. Both movements are discrete solid-object motions driven by physical force.

Background elements (purple walls, gym equipment, posters) remain stationary with no shifting or environmental fluid motion (fire, water, smoke, wind).


Two individuals run on adjacent treadmills; the person in a bright green sleeveless top leads, followed by a person in a black outfit with yellow accents. The lead runner shifts their hands on the treadmill’s side while the trailing runner adjusts their position, interacting with their console. The camera remains stationary, capturing their side-by-side movement in a gym setting.

Two people (man in green sleeveless shirt, woman in dark top and shorts) are running on stationary treadmills, exhibiting leg/upper-body locomotion due to their own physical effort.

The background (walls, gym equipment) remains static with no uniform shifting; no fire, water, smoke, or wind observed.


A baby in a white onesie with a circular logo lies on a bed, eyes open and looking upward. The baby shifts slightly, mouth open. A hand enters from the left, gently touching the baby's shoulder and moving upward. The hand remains in contact with the baby's chest area as the baby’s position adjusts minimally. The camera maintains a close-up perspective with slight movement, focusing on the baby and the hand. The background consists of white bedding with minimal detail.

The baby's minor movements (head turning, body shifting) and the person's hand movements (adjusting the baby's clothing) are the discrete solid objects in motion.

The background (bedding) is stationary. No environmental fluids (fire, water, smoke) or wind effects observed. Background does not shift uniformly, indicating no camera motion.


A person in dark clothing stands near a small dog crouched on the green turf of an indoor field; the person then walks away toward the far end of the field, and the dog rises and follows closely behind. The camera remains static, capturing the subjects from a fixed position with minimal background detail.

A person and a dog are moving. The dog is running and the person is walking, both moving from left to right across the frame.

The background (boards, walls) is static with no fluid or environmental motion. There are no signs of fire, water, smoke, or wind.


A small child wearing a dark top and light pants runs leftward across a gravel path in front of a lattice wall, then stops and turns to face the wall. The background includes a grassy area and a plant-covered lattice wall. The camera remains static with slight movement.

A child is present and exhibits very subtle movement (slight shifts in position, possibly shifting weight or minor locomotion).

The background (wall, vines, grass) shows no significant shifting or fluid motion. No fire, water, smoke, or wind observed. Background elements are static.


A man in a blue shirt, dark shorts, and blue cap walks across a street from left to right, exiting the frame as the camera pans right to reveal a black dog standing near a fire hydrant on the sidewalk in front of a yellow building with rounded trees, with other pedestrians visible in the background.

A man in a blue shirt and a black dog are moving across the street; their motion is tracked as distinct solid objects with clear locomotion.

Background elements (buildings, trees, pavement) remain static relative to each other across frames. No fire, water, or wind-driven motion observed.


RAW CAPTION: Okay, let's tackle this captioning task. First, I need to understand the rules. The user wants a concise chronological paragraph focusing on the motion and behavior of main subjects. They mentioned the video has several clips, so I need to go through each frame in order.

Starting with the first frame: a person playing a violin. The description says they're wearing a dark outfit with a gold belt. The hands are moving, so I should note the violin being played. Then the next frame shows the same person, maybe a different angle, still playing. Then there's a switch to a band scene with a guitarist, maybe a bassist? The third frame is a crowd dancing, so I need to describe that. Then another shot of the band, maybe a different angle. The fourth frame is a red-tinted crowd, so the color is important here. Then the fifth frame is the band again, different lighting.

Wait, the user says to focus on main subjects in chronological order. Let's list the frames:

0.0s: Violinist playing, dark outfit, gold belt.

0.3s: Same violinist, maybe different angle, still playing.

1.4s: Band scene with guitarists and drummer in the background.

2.5s: Crowd dancing, red lighting.

3.6s: Another band scene, maybe different lighting.

4.7s: Band playing, dark setting.

Wait, the user's example input shows timestamps up to 4.7 seconds. So the video sequence is:

1. Violinist (0.0), 2. Violinist (0.3), 3. Band (1.4), 4. Crowd (2.5), 5. Band (3.6), 6. Band (4.7). Wait, but the user's input has 5 frames. Wait, the user provided 5 frames with timestamps 0.0 to 4.7, each labeled as [0.3], [1.4], etc. Wait, the initial input has [0.0], [0.3], [1.4], [2.5], [3.6], [4.7] but the actual provided frames are 5 frames: first frame is 0.0, then 0.3, 1.4, 2.5, 3.6, 4.7. Wait, maybe the labels are the time stamps for each frame.

Wait, the user provided 6 frames with timestamps 0.0, 0.3, 1.4, 2.5, 3.6, 4.7. But the problem says "the provided video" which is the sequence of these frames. So the video starts at 0.0 and goes up to 4.7 seconds.

So the chronological order of events in the video:

- 0.0s: Close-up of a person playing violin, dark outfit, gold belt.

- 0.3s: Same violinist, slightly different angle, continuing to play.

- 1.4s: Band performing, guitarist with black jacket, drummer in background.

- 2.5s: Crowd dancing energetically, red lighting.

- 3.6s: Band members playing on stage, guitarist in dark clothing, another musician to the left.

- 4.7s: Band performing under blue lighting.

Wait, but the user's example input for frame [0.0] shows a violinist, then [0.3] same violinist, then [1.4] is a band scene with multiple musicians. Then [2.5] is a crowd dancing. Then [3.6] another band scene. Then [4.7] is a band in dark setting.

Wait, the description for each frame as per the user's input:

[0.0] shows a person with violin, dark outfit, gold belt.

[0.3] same person, maybe moving slightly.

[1.4] Band members (guitarist, drummer) in background.

[2.5] Crowd dancing, red lighting.

[3.6] Band members on stage, guitarist with black clothing, another musician to the left.

[4.7] Band performing, dark background, blue lighting.

Now, the task is to write a chronological paragraph that describes these in order, focusing on motion and behavior, appearance, spatial relationships, camera perspective, and minimal background.

So the main subjects are the violinist, band members, and crowd.

Starting with the violinist: close-up, playing violin, dark outfit with gold belt, hands moving.

Then the violinist continues, maybe the camera shifts slightly.

Then the scene cuts to the band performing with guitarist and drummer.

Then the crowd dancing, red lighting, energetic movement.

Then another

Multiple discrete objects (people) are moving: musicians playing instruments and dancers in a crowd. The motion is due to locomotion and instrument playing.

The background is dark and non-descript in all scenes, with no fluid motion (fire, water, smoke, wind) observed. There are no shifting static background elements (like walls) that would indicate camera motion.


A child in a yellow shirt and dark shorts kneels on a carpeted floor, interacting with a sheet of paper. An adult in a light-colored shirt and shorts approaches from the left, reaching toward the paper. The adult’s hand joins the child’s to adjust the paper, and the child then turns their head while maintaining contact with the paper. The camera remains stationary with slight movement, capturing the interaction from a fixed perspective.

The child and adult are moving their hands and bodies to interact with a piece of paper on the floor.

No shifting backgrounds or fluid/environmental motion (fire, water, wind) detected. Background elements (cabinet, carpet) are static.


Two women in matching light purple-brown corset and long flowing skirts begin with arms raised above heads on a pink-lit stage. They lower arms to sides, sway hips, and shift posture to hands near hips while moving skirts. Stage background includes stone steps; camera remains static.

Two dancers performing coordinated movements: arm raises, hip swaying, body rotations, and hand gestures. Solid, distinct human subjects moving due to intentional physical locomotion (dance).

Background shows static stage elements (purple floor, stone structures) with no shifting or fluid motion. No fire, water, smoke, or wind-driven environmental effects observed.


A pan on a gas stove contains golden-brown shrimp in a thick brown sauce. The pan is lifted and tilted, pouring the shrimp and sauce over green pasta on a white plate. The sauce covers the pasta, and the shrimp are arranged on top, appearing seasoned and glossy. The camera transitions from a top-down view of the pan to a close-up of the plated dish, showing the shrimp and sauce over the pasta. Background elements are minimal, focusing on the cooking and plating process.

Discrete solid objects include the pan (holding shrimp in sauce), the fork (transferring shrimp), and the plates (with pasta). Motion involves the pan being tilted to serve sauce, the fork moving shrimp between pan and plates, and the sauce being poured onto pasta.

The countertop and stationary background elements (e.g., napkin, plate edges) do not exhibit uniform shifting motion; no dominant fire, water, smoke, or wind effects are present.


Two individuals interact in a room. The person in dark clothing gestures with hands toward the person in white clothing, who looks downward and adjusts their position. The dark-clad individual continues gesturing while the white-clad individual responds. The camera remains static, capturing the scene from a fixed perspective.

Two people are visible: one seated playing an instrument (with hand movements) and one standing gesturing. Both exhibit discrete solid-object motion from intentional actions (strumming, gesturing, head movements).

Background elements (red telephone booth, floral wallpaper) remain stationary throughout the video with no shifting or fluid motion (e.g., no fire, water, or wind effects).


A metallic, silver-colored electric drill with a textured, ribbed body is shown in close-up, rotating slightly to reveal its cylindrical shape and grooved surface. A hand enters the frame, gripping the drill from below. The camera maintains a close perspective, shifting angle slightly as the drill is maneuvered against a plain, light-colored background.

A handheld power drill is the primary discrete object; its position shifts slightly due to human manipulation (hand movement), indicating physical force interaction.

The background consists of a plain, static wall with no visible shifting, fluid motion, or environmental effects (e.g., no fire, water, or smoke).


A male diver in swim trunks stands on a high diving board above an indoor pool, then leaps forward and dives into the water, submerging completely. The camera captures the motion from a static wide-angle perspective above the pool deck, showing the diver’s trajectory and the pool’s lane dividers with minimal background detail.

A single swimmer is actively moving through the pool via swimming motions; other individuals on the deck are largely stationary.

The pool water shows minor ripples from the swimmer's movement, not dominant environmental fluid motion; static background elements (walls, flag, scoreboard) remain stationary across frames.


Two girls play string instruments: a taller girl in a sleeveless red dress stands holding a violin, moving her bow across the strings, while a shorter girl in a purple patterned dress sits on a black leather couch, her bow moving on a cello. The standing girl is positioned to the left of the couch, the seated girl in front of it. Background features plain white walls with minimal objects. The camera remains static throughout.

Two solid human subjects: standing violinist (moving arms/bow) and seated cellist (moving arms/bow) exhibit discrete motion from instrument playing.

Background elements (white wall, black leather couch, floor lamp) remain static with no shifting or environmental effects (fire, water, smoke, wind).


A person wearing a black shirt and pink apron stands at a stainless steel sink, holding a plastic bag containing a blue bowl. They spray the bag with a bottle, then move to the countertop, manipulating the bag’s contents. The countertop holds a knife block, paper towels, and other kitchen items. The camera slightly pans to follow the person’s movements.

A person (wearing black top and pink apron) moves a blue plate and a bottle. The person lifts, rinses, and scrubs the plate/bottle under the faucet using hands and a sponge. These are discrete solid objects interacting with physical forces from the person's actions.

No shifting background elements. Kitchen items (knife block, coffee maker, window) are stationary. Water in the sink is actively manipulated by the person (not dominant ambient motion), so no fluid/environmental motion qualifies as primary ambient.


A woman in a teal jacket and black shorts hands a white object to a small girl in a light blue shirt and dark shorts standing near a black pole structure. The woman then turns and walks away, while the girl remains stationary. The background includes a crowd of people on a grassy field. The camera remains static, capturing the scene from a ground-level perspective.

Discrete solid objects: A woman throwing a ball, a child running, and other people moving in the field. These movements are due to locomotion and throwing actions.

Static background elements (trees, grass) show no uniform shifting or significant fluid/environmental motion (e.g., wind-swaying trees are minimal and not dominant).


RAW CAPTION: Got it, let's see. The video starts with a hand throwing a yellow dart at a dartboard. The hand is on the left side, moving towards the board. Then the dart hits the board, and the hand moves away. Next, the hand comes back from the left to throw another dart. Then another dart is thrown. Wait, let's check the frames.

First frame: hand holding a yellow dart, about to throw. Then the dart is thrown and hits the board (frame 2). Then the hand is gone, board has two darts? Wait, frame 3 shows the hand moving towards the board again, then frame 4 the hand is throwing another dart. Frame 5: the hand is gone, but maybe another dart? Wait, the sequence: 0.0 - 1.0: hand throws a dart. 1.0 - 2.0: the dart is on the board, hand moves away. Then 2.0 - 3.0: hand comes back from the left to throw another dart. 3.0 - 4.0: hand throws another dart. 4.0 - 5.0: hand is gone again, maybe the dart is there. Wait, the description says "chronological paragraph describing the provided video."

So let's list the actions: first, a hand (right hand, maybe, but the video shows a hand from the left) throws a yellow dart. The dart hits the dartboard, which has green, red, and black sections. Then the hand moves away. Then the hand comes back from the left to throw another yellow dart. Then the hand throws that dart, which also hits the board. The background is a plain wall, the dartboard is hanging. Camera is static, looking at the dartboard. Need to mention the motion: hand entering from left, throwing, dart hitting, hand moving away. Then repeating for another throw.

So the caption should be: A hand throws a yellow dart toward a wall-mounted dartboard, then withdraws. The hand reappears from the left, throws another yellow dart toward the board, and withdraws. The dartboard features colored segments (green, red, black) with numerical markings. The camera remains stationary, focused on the dartboard against a plain wall.

Check the rules: focus on motion, chronological order. Mention appearance (yellow dart, hand), spatial (hand from left), background minimal. Camera perspective static. Don't include text. Yes.

Let me structure it: First action: hand (left side) throws yellow dart. Dart hits board. Hand moves away. Then hand comes back (left), throws another yellow dart. Dart hits board. Hand moves away. Camera is static, showing dartboard on wall.

So concise: A right hand throws a yellow dart from the left toward a wall-mounted dartboard, hitting the board; the hand then withdraws. The hand reappears from the left, throwing another yellow dart that strikes the board, after which the hand withdraws. The dartboard displays colored segments with numbers, and the camera remains fixed on the board against a plain background.

Wait, check the frames: first frame shows hand holding dart, then dart thrown, then board with dart, then hand coming back, then throwing another, then board with two darts? Wait, the video has 5 frames. Let's list each frame:

Frame 0: hand on left, holding yellow dart, about to throw.

Frame 1: dart is in mid-air, moving toward board.

Frame 2: dart has hit the board (two darts now? Wait, frame 2 shows three darts? Wait no, the first frame (0) has the hand, then frame 1 shows the hand moving away, and the dart is on the board. Wait, the description says:

<0.3 seconds> hand holding yellow dart, about to throw.

<1.4 seconds> dartboard with three darts (maybe? The image shows three darts on the board).

Wait, no: the first frame (0.0) shows a hand on the left holding a yellow dart. Then frame 1 (0.3) shows the hand has thrown, and the dart is on the board (with other darts). Wait, the problem is the video has 5 frames: [0.0, 0.3, 1.4, 2.5, 3.6, 4.7] — wait no, the user provided the frames as:

[0.3] <0.3 seconds> [frame 0]

[1.4] [frame 1]

[2.5] [frame 2]

[3.6] [frame 3]

[4.7] [frame 4]

Wait, the timestamps are: 0.3

No shifting background or fluid/environmental motion. The background (plate and food arrangement) is stationary throughout the video.


tags.  Let's write:  <caption_output>Two men converse in a crowded indoor space. The man on the left, wearing a light gray blazer over a dark shirt, drinks from a glass, then lowers it and speaks. The man on the right, dressed in a black suit and light blue tie, holds a glass and listens. They stand side by side, facing each other. The camera remains steady at eye level.

The man in the gray suit is lifting and lowering a glass to drink, and the man in the dark suit is gesturing with his hand. Background people are moving but are not the focus.

The background shows a crowd of people and a building with windows; no significant ambient environmental motion (fire, water, smoke, wind) is present. Background elements (windows) are stationary.


Three dancers—two in white vests, red shirts, and cowboy hats (one with fringe, one in blue jeans), and one in a red shirt and dark pants—stand on a stage with colorful lighting. They begin walking left to right across the stage, then turn to walk toward the right side. The camera pans to follow their movement, exhibiting a slight shake. Background elements include a band but remain minimal.

Three dancers in red shirts and white pants are performing a choreographed dance routine, moving across the stage. Band members in the background are also present but less prominent.

The background (stage, amplifiers, walls) is stationary. No fire, water, smoke, or wind are present. The lighting changes are controlled and not ambient environmental motion.


A young boy wearing a gray and black short-sleeved shirt, blue shorts, and brown shoes walks across a wooden kitchen floor holding a yellow broom with green handles. He moves from the right side of the frame toward wooden cabinets, turns, and walks toward the sink area under a window. The camera follows his motion with slight movement. Background includes kitchen cabinets and countertop items.

A child carrying a yellow broom moves across the kitchen floor, sweeping and repositioning themselves while holding the broom. The broom and child's motion is intentional locomotion.

The kitchen background (cabinets, dishwasher, flooring) shows no uniform shifting or fluid motion. No fire, water, smoke, or wind-dominated phenomena are visible.


A small child wearing a dark top and white pants sits on grass, holding a phone to their mouth with both hands. A blue toy bucket and a stick lie on the ground to the left. The child remains seated, slightly adjusting their grip on the phone while looking downward. The background features a fence and buildings, but the camera stays stationary, capturing the scene from a fixed, eye-level perspective.

A baby is seated on grass, exhibiting discrete hand movements (e.g., bringing hands to mouth, adjusting posture) as the primary visible motion.

Background elements (fence, buildings, grass) show no significant shifting or fluid motion; no fire, water, smoke, or prominent wind-driven environmental effects observed.


On a dim stage, a person in dark clothing stands left, raising a camera to photograph; another person in dark clothing stands right, adjusting ropes near a large, warm-lit cylindrical structure. The photographer shifts camera position, while the rope handler pulls ropes, both maintaining their positions against the backdrop. The scene is captured from a fixed angle with slight camera shake.

Two distinct human subjects (solid objects) are actively manipulating objects: one handles a large covered structure with hand movements, while the other holds a tool/hose near a glowing area. Their motions are intentional and tied to physical interactions.

Background elements (dark walls, stage structure) are static and show no shifting. No fluid/environmental motion (fire, water, smoke) dominates the scene; the glowing object appears to be a controlled light source or model rather than an ambient fluid.


RAW CAPTION: Got it, let's tackle this caption. First, the video shows a person in a batting cage. The main subject is a person wearing a red and white shirt and dark pants, holding a bat. The sequence starts with them standing, then swinging the bat to hit a ball. Wait, in the frames, the first frame has the person holding the bat, then in frame 2 they swing, frame 3 they're in the swing motion, frame 4 they're following through, and then frame 5 shows them in a different position, maybe after hitting the ball, but the background changes? Wait, no, the first part is a batting cage with netting, and then frame 5 has a different background—maybe the cage is part of a larger area. Wait, need to check the description. The user provided frames: 0-5. Let's parse each frame.

Frame 0: Person stands, holding bat, wearing red/white shirt, dark pants, cap. Ball is on a stand in front of them. Background: chain-link fence.

Frame 1: Person swings bat, starts to move back.

Frame 2: Person in middle of swing, body twisted.

Frame 3: Person completes swing, bat is up, ball is hit? Then frame 4: Person is now leaning forward, maybe after hitting, and then frame 5: The scene changes—maybe the camera angle shifts? Wait, frame 5 shows the person on a green surface with a bucket and other objects, so maybe the camera moved to show a different part of the cage.

Wait, the task is chronological. So the sequence of actions:

Starts standing in batting cage, holding bat and ball (ball on stand). Then swings the bat, hits the ball (as they swing), then follows through, and then the camera shifts to a wider shot showing the ground (green) with a bucket and other items.

Wait, let's check the description again. The user's frames: 0 to 5. Let's map:

0: Person in cage, red/white shirt, dark pants, holding bat, ball on stand.

1: Person swinging bat.

2: Continuing swing, body rotated.

3: After swing, maybe ball is hit, and person is in follow-through.

4: Person moves to the right (since in frame 4, the background changes to a green floor, bucket, etc.)

5: The view is wider, showing the cage netting, green floor, bucket, and the person now near the bucket.

Wait, but need to focus on motion. The main subject is the person swinging a bat. Let's structure:

A person wearing a red and white short-sleeve shirt and dark pants, standing in a batting cage, holds a bat and a ball on a stand. They swing the bat forward, completing the motion, then lower the bat and step back. The camera then shifts to a wider angle, showing the person on a green mat with a bucket nearby, as the batting cage netting remains in the background.

Wait, but need to be concise. Let's list the chronological steps:

1. Person stands, holding bat and ball. (Appearance: red/white shirt, dark pants, cap.)

2. Swings bat in a full arc.

3. After swinging, moves to a different part of the cage (green mat, bucket visible).

Check the rules: focus on motion in chronological order, brief appearance, spatial relationships, camera perspective.

Start: person in batting cage, red/white shirt, dark pants, cap, holding bat and ball. Swings bat (forward, then back), completes swing, then the scene shifts to a wider view showing the green floor and a bucket.

Wait, the frames: frame 0: person holding bat, ball on stand. Frame 1: swinging. Frame 2: mid-swing. Frame 3: follow-through. Frame 4: person leaning, background shows green mat and bucket. Frame 5: same wider shot.

So the motion: The person, dressed in a red and white shirt and dark pants, stands in a batting cage, holding a bat and a ball. They swing the bat forward, then follow through, and the camera angle shifts to a wider shot showing the green floor with a bucket and the cage netting.

Wait, but need to be precise. Let's see:

- Chronological: initial stance, swing, follow-through, camera shift.

- Appearance: red and white shirt, dark pants, cap.

- Spatial: in front of batting cage netting; after swing, on green mat.

- Camera: starts close-up, then shifts to wider angle.

Now, write concisely.

A person wearing a red and white short-sleeve shirt and dark pants stands in a batting cage, holding a bat and a ball on a stand. They swing the bat forward

Batter (solid object) swings bat and collides with baseball; baseball and bat move due to explicit physical forces (swing collision) and locomotion.

Chain-link fence and concrete wall remain static with no uniform shifting; no fluid/environmental motion (fire, water, wind) observed.


RAW CAPTION: Got it, let's tackle this. First, the video shows two children in a room. The camera is upside down, so I need to note that. The main subjects are two kids, one in a light blue shirt with some designs, the other in a dark blue shirt. They're moving their hands, maybe playing or interacting. Let's check the order: the first frame, they're near the window with blinds and a curtain. Then in subsequent frames, their arms move, hands gesturing. The background has a framed picture on the wall. The camera is fixed but upside down, so the perspective is top-down but inverted. Need to describe motion chronologically: their hands move up and down, maybe reaching or waving. Spatial: one is to the left (but since upside down, maybe above or below? Wait, the video is rotated 180 degrees, so the kids are upside down in the frame. So their heads are at the bottom of the frame. Wait, no: the video is rotated, so when they say "upside down," the actual orientation is inverted. So the kids are in the frame with their heads pointing down (in the video's orientation). So the description should reflect that their positions are as seen, even though rotated. So first, two children (one in light blue, one in dark blue) are visible. They move their hands, possibly interacting. Background: window with blinds, curtain, framed picture. Camera is static but the video is rotated, so the view is inverted. Wait, the camera perspective: the video is shot from a top-down angle but rotated, so the camera is above looking down, but the image is flipped. So the camera is fixed, but the image is inverted. So in the caption, need to say the camera perspective is top-down (but the video is rotated, so the view is upside down). Wait, the problem says "conclude with the camera perspective and movement". The camera here is static, but the video is upside down. So the camera is fixed, but the orientation is inverted. So the perspective is top-down (as the camera is looking down on the subjects, but the video is rotated). Wait, no—when you rotate the video 180 degrees, the camera is still looking down, but the frame is flipped. So the camera is positioned above the subjects, looking down, but the video is rotated. So the perspective is top-down (inverted). But the rules say "conclude with camera perspective and movement". So movement: static? The video frames show the kids moving, but the camera is fixed. So camera is static, upside down view. Let's structure the caption:

Chronological order: The video starts with two children in a room, one wearing a light blue shirt with designs, the other in a dark blue shirt. They are positioned near a window with blinds and a curtain. The children move their hands, with their arms and hands gesturing; one child moves their hand up and down, while the other also moves their hands. The background includes a framed picture on the wall. The camera maintains a static, upside-down perspective, capturing the scene from above.

Wait, need to check rules: "Focus primarily on motion and behavior of main subjects (people/animals/objects) in chronological order." So first, describe what happens first. In the video, the first frame shows the kids near the window. Then their hands move. So the motion: the children's hands are raised and moving. Let's list each frame:

Frame 0: Two kids (one in light blue, one in dark blue) near window with blinds. One hand is up.

Frame 1: Both hands up, maybe gesturing.

Frame 2: Hands moving, maybe one child moving hand.

Frame 3: One child's hand reaching down.

Frame 4: Hands moving.

Frame 5: Hands gesturing.

So motion: the children interact with their hands, moving them up and down, possibly playing. Their shirts: light blue (with designs) and dark blue.

Spatial: the window is behind them, curtain below the blinds.

Camera: static, but the video is rotated 180 degrees, so the view is upside down.

Now, the caption should be concise. Let's draft:

"Two children, one in a light blue shirt with designs and the other in dark blue, interact by moving their hands near a window with blinds and curtain. Their hands gesture up and down in chronological sequence. The camera maintains a static, upside-down perspective."

Wait, "chronological order" so describe the sequence. First, they are present. Then their hands move. So:

"In the video, two children (one in a light blue shirt with designs, the other in dark blue) are near a window with blinds and a curtain. They sequentially raise and move their hands, interacting with gestures

Two people are visible. The person on the right is moving their hand to adjust the blinds, causing the blinds to shift. The person on the left is also moving their head and hands.

The background elements (window frame, curtain) are static and show no uniform shift. No fire, water, or smoke is present. The primary motion is due to the people interacting with the blinds.


A person wearing a gray hoodie and jeans enters from the right, carrying a white bag, walking leftward past a brick column toward the porch. The camera remains stationary, capturing the scene from a fixed angle.

A person wearing a hat walks from the right side of the frame toward the left, turns around, and then walks back toward the right.

The background (wall, pillar, ground) shows no uniform shifting or fluid motion. No fire, water, smoke, or wind is present in the scene.


RAW CAPTION: Got it, let's tackle this. First, I need to describe the video chronologically. The main subjects are two people: one lying on a table, shirtless, and another standing, wearing black top and red pants. The standing person is massaging or working on the back of the lying person.

Looking at the frames: in [0.0], the standing person is applying pressure to the back. The lying person is on a black table, face down, hair light-colored. The standing person moves their hands, maybe adjusting. The background has gym equipment, but minimal.

Chronological order: the standing person starts massaging, then continues, maybe shifting position slightly. The lying person remains still, positioned on the table. Spatial: standing person is to the right of the lying person (since lying person is face down, back exposed).

Camera perspective: slight shake, maybe handheld, as it moves a bit. Background is gym, but just mention minimal.

Need to be concise. Let's structure:

- Main subjects: shirtless man (light hair, lying face down on black table), person in black top and red pants (standing).
- Motion: the standing person uses hands on the lying man's back, moving them.
- Spatial: standing person is to the right of the lying man.
- Background: gym equipment visible but minimal.
- Camera: slight shake, handheld.

Check rules: focus on motion/behavior, appearance, spatial, camera. Exclude background unless essential. Here, gym is background but minimal.

So draft: A shirtless man with light hair lies face down on a black treatment table, his back exposed. A person wearing a black top and red pants stands to his right, using their hands to massage and adjust the man’s back. The standing person moves their hands rhythmically over the man’s shoulders and upper back, maintaining consistent pressure. The camera remains stationary with a slight shake, capturing the interaction in a gym setting with minimal background details visible.

Wait, but need to be concise. Let's trim.

"A shirtless man with light hair lies face down on a black table, his back exposed. A person in a black top and red pants stands to his right, using their hands to massage and adjust his back. The standing person moves their hands rhythmically over the man’s shoulders and upper back. The camera is slightly shaky and handheld, capturing the interaction with gym equipment visible in the background."

Check for chronological order: the actions happen in sequence (standing person starts, moves hands).

Wait, the frames show the standing person's hands moving from one spot to another. So "massage and adjust" covers the motion.

Also, "shirtless man" and "black top and red pants" for appearance.

Spatial: "stands to his right" (since lying man's back is exposed, the standing person is on one side).

Camera: "slight shake, handheld".

Background: "gym equipment visible in the background" – but rule e says minimal background unless essential. Maybe omit "gym" but the video is in a gym, but maybe necessary to know context. Wait, the problem says "exclude text recognition, named characters, or stylistic analysis". But background as gym is context. The instruction says "keep background descriptions minimal unless essential for understanding motion". Since the motion is happening in a gym, but the motion itself (massage) doesn't require knowing it's a gym. Maybe omit background except if essential. But the frames show gym equipment, but maybe not essential. So maybe just "in a gym-like setting" but rule says minimal. Let's see the example in the rules. Wait, the example isn't given, but the rule says minimal. So perhaps just describe what's essential. Since the background isn't crucial for the motion, maybe omit.

Wait, the original video: the background has gym equipment (exercise machines), but the main action is the massage. So the caption should focus on the main subjects. So background can be mentioned as "gym equipment visible" but minimal.

But let's check the rules again: "e) Keep background descriptions minimal unless essential for understanding motion." Since the motion (massage) doesn't depend on the gym context, maybe don't mention. So perhaps the background is not needed.

So revised: "A shirtless man with light hair lies face down on a black table. A person in a black top and red pants stands to his right, massaging his upper back and shoulders with their hands, moving rhythmically. The camera maintains a slight shake, capturing the interaction."

Wait, but the lying person's position: the frames show he's leaning forward slightly, hands on the table. Wait, in the frames, the lying person is leaning forward, head on the table. Wait, looking at the first frame: the man


A person in a blue, white, and red striped polo shirt stands against a dark background with a string of colorful lights above. Initially still, they raise their right hand to their forehead, then use both hands to adjust their hair, followed by bringing both hands together near their chest. The camera remains static throughout, capturing the individual’s movements against the minimalistic backdrop with minimal background detail beyond the string lights.

A person is making hand gestures: covering face, adjusting hair, and moving hands to the head.

The background (dark wall with static string lights) shows no shifting or fluid motion; no fire, water, or wind is present.


A hand enters from above, pointing at a green block, then pushes it to reveal a red building with a sign behind. The hand continues gliding across the scene, interacting with a green hill structure. The camera maintains a top-down perspective, tracking the hand's motion over the paper cutout landscape.

White cloud paper cutouts and green hill paper cutouts are discrete objects being manually repositioned by a hand, indicating locomotion through manual manipulation.

The background elements (blue sky, yellow ground, green hills) remain static with no fluid or environmental motion (fire, water, smoke, wind); the motion originates from the hand manipulating paper cutouts.


Discrete solid objects: hands (person) interacting with cards on the table. The hands manipulate cards through physical contact, indicating explicit locomotion and force application.

The background includes a wooden wall and table surface; no fluid motion (fire, water, wind) is present, and background elements do not shift uniformly across the screen.


A person in a white coat gestures toward a woman in a dark purple sleeveless top holding a newborn baby wrapped in a light blanket; the woman looks down at the baby, then turns to the person, engaging in conversation while keeping the infant close to her chest, with the camera maintaining a steady medium shot focused on the interaction between the three subjects.

Nurse's hands gesture (clapping/moving), woman's head shifts slightly while holding the baby; baby remains relatively still in the cradle.

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


Two individuals, one in a yellow shirt holding a green bottle and the other in an orange shirt holding a blue and red cup, raise their containers to their mouths and drink. The person in yellow is positioned to the left of the person in orange, who has long blonde hair. The camera maintains a close-up view with slight movement throughout the sequence, capturing the motion of drinking against a dark background.

Two girls (discrete solid objects) move their heads and arms while drinking from cups. The cups are also moving due to the drinking action.

The background is dark and not visible, showing no shifting or fluid motion.


tags, concise paragraph. Avoid any markdown. Make sure it's chronological, no text recognition, minimal background.  Let me draft: A gloved hand holds a small, light-colored object on a white and orange striped cloth. Another gloved hand uses a small tool to carefully manipulate the object. The person’s hands, one white and one gray, work closely together over the cloth. The camera remains in a close-up, steady perspective throughout. </think>  <caption_output>A gloved hand holds a small, light-colored object on a white and orange striped cloth, while another gloved hand uses a small tool to carefully manipulate it.
