A boy in a green and white shirt manipulates bright pink cups with black logos in a kitchen setting; initially arranged in a pyramid on a countertop, he picks up multiple cups, moves them across the counter, and rearranges their positions while standing behind and to the side of the cups. The camera remains fixed, capturing the boy’s actions against a backdrop of wooden cabinets and a stool.

A boy manipulates pink plastic cups via hand movements (stacking, knocking over), resulting in discrete, solid object motion driven by physical forces (hand contact, collisions).

Static kitchen background (cabinets, stove, furniture) shows no uniform shifting; no fire, water, smoke, or wind-driven motion present.


A person (red shirt) is dribbling and shooting a basketball; the ball moves through the air toward the hoop under gravity. Both objects exhibit discrete, solid-body motion due to physical forces (locomotion, projectile motion).

Background elements (trees, fence, building) show minimal sway but no dominant fluid motion (fire, water, smoke). Wind effects on trees are negligible compared to primary subject motion. Static background remains largely consistent with no uniform shifting.


A person with long brown hair and a light-colored top manipulates a white cloth on a dark surface, smoothing it with both hands before lifting and folding the cloth. In the background, a clear plastic container sits to the right. The camera maintains a static top-down perspective throughout.

A person is actively folding a white paper; the person's hands and body move to manipulate the paper.

Static background with no shifting elements or fluid/environmental motion. Background objects (plastic container, table) are stationary.


RAW CAPTION: Got it, let's break this down. The video starts with two women in black outfits with blue lights on them. One is in a black dress, the other in a black top and shorts. They're in a dimly lit room with blue lighting. The woman in the dress is opening a door with bright blue lights. As the door opens, they step through. The first woman walks through, then the second. The background is a dark room with a blue glow. The camera is stationary, capturing their movement from the doorway into the room. Need to describe the sequence: two women, their actions (opening door, stepping through), spatial relationships (one opening door, the other entering), then camera perspective.

Let's check the rules. Focus on motion chronologically. Appearance: two women, one in black dress, one in black top and shorts with blue lights. Number: two. Motion: first woman (in dress) opens door, then both step through, moving from right to left as they enter the room. Background is minimal, so keep it brief. Camera is static, maybe slight shake? Wait, the video description doesn't mention camera movement, but in the problem statement, it's up to the captioner. The user says "Conclude with camera perspective and movement". The video shows a fixed camera, so maybe "static" or "stationary".

Wait, the initial frames: first frame, door is open. Second frame, door is being opened. Third frame, door is open, they're stepping through. Fourth frame, the door is fully open, and they're inside. So the sequence is the woman in the dress (back to camera) opens the door, then the other two women walk through.

So chronological order: the woman in the black dress stands near the door, opens it (hands on the door frame), then two women (one in black top with blue lights, one in similar outfit) walk through the door into the room. Wait, the video shows two women: one is in front, opening the door, the other two are stepping through. Wait, in frame 0: two women in front, one in black dress, one in black top and shorts. Wait, no: the first frame shows three people? Wait, no. Wait, the first frame: a woman in black dress (back to camera) opening a door, and two women (front) in black tops with blue lights and shorts. So there are three women? Wait, no, let's check:

Frame 0: woman in black dress (back to camera) opening door, two women in front (black tops, blue lights, shorts). So three people? Wait, the first frame: left side, a woman in black dress (back), then two women in front (black tops, blue lights, shorts). So three people. Wait, but the problem says "main subjects". Let's count.

Wait, the first frame: person on right (black dress, back to camera), two people on left (two women in black tops, blue lights, shorts). So three people. But in the description, the woman in the dress is opening the door. Then, as the door opens, the two women walk through. Let's check the frames:

Frame 0: woman in dress (right) opens door, two women (left) standing.

Frame 1: same, but door is opening more.

Frame 2: woman in dress has door open, two women are entering.

Frame 3: woman in dress is now walking into the room, the two women are further in.

Wait, maybe the first woman (in dress) is opening the door, then the other two women step through. So three people total: one opening the door, two entering.

Wait, the user's example says "two women", but let's check the video:

[0.0 second] Three people: woman in black dress (right, back), two women in front (black tops, blue lights, shorts).

[1.4 second] Same, door is opening.

[2.5 second] The door is open, the two women in front are walking through, the woman in dress is standing near the door.

Wait, maybe the woman in the dress is the one opening the door, and there are two other women following. So three people total.

Wait, let's re-examine the description:

"three women: two in black outfits with blue lights and shorts, and one in a black dress. The woman in the dress is opening a door, then the two women walk through. Wait, but in the video, the two women in black outfits are the main ones entering, and the woman in the dress is facilitating the door.

So step by step:

- At 0.0s: Two women in black top, shorts, blue lights are standing inside a room with blue lighting. A

Two distinct solid objects (people) move: one person in a blue jersey walks through a doorway while holding a bottle, and another person in a dark dress interacts with the door. Their motion is locomotion and hand gestures due to physical forces.

Background elements (door frame, walls, blue lighting) show no uniform shifting or fluid/environmental motion (fire, water, wind). No ambient environmental phenomena detected.


RAW CAPTION: Got it, let's tackle this. First, the video shows two people in a squash court. The main subjects are the child and the adult. The child is holding a squash racket, wearing dark clothes and gray pants. The adult has a jacket with "WAPDA" on the back, dark with red stripes.

Chronologically: At the start, the child is standing near the front wall. Then the child moves forward, swings the racket, and maybe hits the ball (but we don't see the ball). The adult is in the foreground, moving. Let's check the frames. Frame 0: child is near the wall, adult is right. Frame 1: child is still, adult turns. Frame 2: child moves left, adult's hand moves. Frame 3: child swings racket, maybe hits. Frame 4: child moves towards the right, adult watches. Frame 5: child is near the corner, adult is in front.

So motion: Child starts near front wall, moves left, swings racket (action), then moves right. Adult is in front, turns, maybe reacts. Spatial: Adult is in front of the child initially, then the child moves around. Background is the court with walls, minimal. Camera is fixed? The video shows the camera moving a bit, maybe following the action.

Now, rules: Focus on motion, chronological. Describe appearance briefly: child (small, dark outfit, gray pants), adult (dark jacket with red stripes, "WAPDA" but exclude text? Wait, rule f says exclude named characters, so maybe just describe the jacket as dark with red stripes, not the text. Wait, rule f: exclude text recognition. So "WAPDA" is text, so don't mention it. So adult's jacket is dark with red stripes.

Appearance: child - small, dark clothing, gray pants. Adult - taller, dark jacket with red stripes.

Motion: Child moves from near the front wall towards the left, swings the racket, then moves towards the right. Adult stands in front, turns, and gestures.

Chronological order: First, child stands at the front. Then child moves left, swings racket. Then child moves right, adult observes.

Background: squash court with wooden floor, green and blue walls, but minimal.

Camera: The camera seems to be static but might have a slight movement, maybe following the child's action.

Putting it all together: concise paragraph.

Let me structure:

In a squash court, a small child in dark clothing and gray pants stands near the front wall, holding a squash racket. The child moves leftward, swings the racket, then shifts rightward. A taller adult in a dark jacket with red stripes stands in the foreground, turning slightly and gesturing. The camera remains mostly fixed, capturing the subjects' movements within the enclosed court space.

Wait, need to check rules. Exclude text recognition, so "WAPDA" is text, so don't mention. Also, mention spatial relationships: adult is in front of the child initially, then child moves around.

Also, chronological: start with child standing, then moving left, swinging, moving right. Adult's actions: turning, gesturing.

Check for minimal background: "enclosed court space" is okay, but since background is minimal, just say "squash court".

Let me draft:

A small child in dark clothing and gray pants stands near the front wall of a squash court, holding a squash racket. The child moves left, swings the racket, then moves right toward the corner. A taller adult in a dark jacket with red stripes stands in the foreground, turning slightly and gesturing. The camera remains mostly static, capturing the sequence within the court.

Wait, in the frames: frame 0, child is near front, adult is right. Frame 1: child still, adult turns. Frame 2: child moves left, adult gestures. Frame 3: child swings, adult steps back. Frame 4: child moves right, adult watches. Frame 5: child is near corner, adult is in front.

So chronological steps: child starts at front wall, then moves left, swings racket (action), then moves right. Adult is in front, turns, gestures, steps back.

So: A small child in dark clothing and gray pants stands near the front wall of a squash court, holding a squash racket. The child moves leftward, swings the racket, then shifts rightward toward the corner. A taller adult in a dark jacket with red stripes stands in the foreground, turns slightly, gestures, and observes the child's movements. The camera remains mostly static, capturing the subjects' actions within the enclosed court.

Check for rules: a) motion and behavior in chronological order. b) appearance and number (child, adult; describe appearance). c) spatial relationships (adult in foreground, child near wall). d) camera

Two squash players moving via locomotion and hitting a squash ball; all motion is distinct and attributable to human physical forces (e.g., running, swinging rackets).

Static background elements (walls, court lines) show no uniform shifting; no fluid or environmental motion (fire, water, smoke, wind) observed.


A person wearing a light-colored patterned shirt uses their hands to adjust a white cloth covering a rolled object on a kitchen counter, lifting the cloth to expose a dark item beneath and then moving the cloth aside. A metal mixing bowl and cabinets are visible in the background, and the camera maintains a close-up, static perspective.

A person's hands are actively manipulating a white towel, with discrete physical interactions (folding, adjusting) between the hands and the towel.

The kitchen background (sink, cabinets) shows no shifting or fluid motion; no fire, water, or smoke is present.


A group of children, mostly wearing yellow shirts with some in black, sit cross-legged on a floor. They begin seated still, then clap their hands together, followed by raising both hands above their heads. The camera remains stationary, capturing the group from a frontal perspective.

Children in yellow shirts are moving: clapping and raising hands above their heads.

Background is static (blue wall, posters) with no shifting or fluid motion. No ambient environmental elements (fire, water, smoke, wind) are present.


Two individuals sit on a wooden floor facing a checkers board; one wears a red top and black pants while the other is clad in blue clothing. The person in red moves their hand toward the board, adjusting pieces, while the blue-clad individual manipulates pieces on the opposite side. Both engage with the board as the camera maintains a top-down perspective with a slight shake, capturing minimal background details.

Two individuals (left in red, right in blue) interact with a checkers board, moving their hands to manipulate checkers pieces. Discrete solid objects (hands, checkers) exhibit deliberate movement.

Background elements (floor, wall) show no significant shifting or uniform motion. Minor steam/smoke is visible but not dominant; not indicative of fluid/environmental motion.


A man in a blue shirt and dark pants lifts a weighted barbell above his head in a gym, then lowers it, allowing the barbell to fall to the floor. The scene transitions to darkness. Camera remains stationary throughout.

The person in the blue shirt performs a weightlifting motion (lifting the barbell overhead, lowering it, and walking away). The barbell and weights are discrete solid objects moving due to explicit physical forces (muscular effort). Another individual briefly enters the frame but is incidental.

The gym walls, weight plates, and floor remain static throughout. No fluid motion (fire, water, smoke) or wind is observed. Background elements do not shift uniformly, indicating no ambient environmental motion.


A hand holding a brown marker enters the frame, adding small dots to the face of a line-drawn girl with long wavy hair and a dress. The hand continues detailing the face with dots before moving away, transitioning the drawing to a fast-food fry container, all captured from a top-down perspective with no camera movement.

Hand (discrete solid object) moving to draw on the whiteboard.

Static whiteboard background with no fluid or environmental motion observed.


A man in a denim jacket and white shirt gestures toward a large tan dog mascot wearing a blue and white jersey. The mascot turns and walks through a crowd, with the man following closely. The camera pans to follow the mascot’s movement as it navigates through spectators.

Discrete solid objects include a person in a plaid shirt pushing a mascot (dog costume), followed by the mascot being moved through a crowd; these movements result from explicit physical forces (collision, locomotion).

The background elements (walls, structures) show minimal uniform shifting, with no fire, water, smoke, or wind present, ruling out ambient_environmental motion.


A person wearing a gray shirt cuts a medium-sized round orange on a cutting board with a knife, slicing the fruit into pieces while holding it firmly. The orange is positioned centrally on the board, and the person's hands move to separate the fruit as the knife cuts through it. The camera remains stationary, focusing on the cutting action against a kitchen background with minimal visible details.

The person's hands and a knife are moving as they cut an orange. The orange is being sliced, causing small displacements of the fruit. All motion is from discrete solid objects interacting physically.

Kitchen background (cabinets, countertop) shows no shifting or environmental motion (no fire, water, smoke, or wind). Background elements remain static throughout the clip.


A hand holds a gold wristwatch with a black bezel and intricate mechanical movement, rotating it slightly to display the face, then tilts the watch to reveal its side profile and gold link bracelet. The camera maintains a close-up perspective, following the watch’s motion against a plain background.

A gold and black watch is being held and rotated by a hand. The motion is caused by the hand physically manipulating the watch (discrete solid object interaction).

The background is a static, uniform light color with no shifting or environmental elements. No fire, water, smoke, or wind motion is present.


A man in a blue shirt, dark shorts, and red sneakers lifts a heavy black barbell from the floor, raising it overhead in a clean motion, then lowers it back down in a garage with shelves and a bicycle visible in the background. The camera remains stationary throughout.

Person performing weightlifting (barbell movement) with distinct locomotion (squatting, lifting, lowering). Barbell and person exhibit solid-body motion due to applied force.

Background elements (shelves, bicycle, storage units) remain stationary with no uniform shifting. No fire, water, or wind-driven motion detected.


A person wearing a light-colored shirt with dark patterns and a white collar sits at a dark table in front of a tiled wall. The individual's hands move slightly across the table surface. The camera remains stationary throughout the sequence.

The person exhibits minimal head and body movements, likely due to natural physical forces such as adjusting posture or slight shifts in seating.

No shifting backgrounds or fluid/environmental motion observed. The patterned wall remains static throughout the video.


A person crouches near a house wall, filling water balloons from a faucet. They first hold a clear balloon under the stream, then replace it with a pink balloon, and finally a white balloon, each being filled sequentially. A bowl of colorful, inflated balloons sits on gravel to the left of the person. The camera remains static, focusing closely on the hands and balloons, with minimal background details visible.

Person's hands manipulate a balloon (changing colors: red → pink → light purple), moving it against the window frame. Bucket of balls is static.

No shifting background elements; wall and window frame remain static. No fluid environmental motion (e.g., fire, water, smoke, wind) observed.

Static background elements (windows, hanging lights, walls) show no uniform shifting or fluid motion; no fire, water, or wind effects observed.


Dozens of performers in red jackets, white hats, and black pants march forward in a tight line along a street, playing guitars and drums in unison. They move rhythmically, with some members visible ahead while others follow closely behind. The camera follows the procession from a moving vehicle, panning slightly left to capture the group’s steady march, maintaining a slight shake as it tracks their progression past tree-lined sidewalks and scattered spectators. Background details remain minimal, emphasizing the band’s synchronized motion.

Marching band members (solid objects) moving in formation via locomotion (walking), with discrete motion consistent with physical forces (muscle movement, foot impact with ground).

Static background elements (trees, street) remain stationary; no shifting or fluid environmental motion (fire, water, smoke) observed.


RAW CAPTION: Got it, let's tackle this captioning task. First, the video starts with a weather map showing the US. There's a person in a dark suit standing to the right of the map. The person gestures with their hands while speaking. Then, the map changes to a "Friday Forecast" view focused on Colorado, with temperature numbers and locations like Steamboat, Grand Junction, etc.

Following the rules: focus on motion/behavior chronologically. The main subject is the person, then the map transition. Appearance: person is in dark suit, map has "CURRENT WEATHER" text then "FRIDAY FORECAST". Spatial: person is to the right of the map initially, then map changes. Camera movement: probably a static shot of the person next to the map, then the map shifts to the Colorado forecast. Background is the weather maps, minimal. Exclude text recognition (since rule g says exclude text, but wait—rule f says exclude text recognition, so we don't mention "CURRENT WEATHER" text). Wait, the rules say: Exclude text recognition, named characters, or stylistic analysis. So don't mention the text labels.

So the key points: person gestures in front of the weather map (US), then map changes to Colorado forecast. The person is a single person in a dark suit, moving hands. Spatial: person to the right of the map. Then the map transitions. Camera perspective: static, maybe pan? Wait, the video goes from one map to another, so the camera might stay focused on the map area but the content changes.

Need to write chronologically: first, person gestures in front of US weather map, then map transitions to Colorado forecast. Mention the person's appearance (dark suit, gestures), spatial (to the right of the map), then the map change. Camera: static shots, maybe the map zooms in or shifts.

Let's structure: A person in a dark suit stands to the right of a U.S. weather map, gesturing with their hands as the map displays current weather patterns. The map then transitions to a closer view of Colorado’s Friday forecast, showing temperature markers over specific regions. The camera remains static throughout, focusing on the map and the person’s movements.

Check rules: a) motion: person gestures, map transitions. b) appearance: dark suit, map content (but exclude text, so maybe just "weather map" without specific labels). c) spatial: person to the right of map. d) camera: static, no movement. e) background minimal. f) exclude text. g) no reasoning.

Wait, the first part: "A person in a dark suit stands to the right of a U.S. weather map, gesturing with their hands as the map displays current weather patterns." Then "The map then transitions to a closer view of Colorado’s Friday forecast, showing temperature markers over specific regions."

But the rules say exclude text recognition, so we don't mention "CURRENT WEATHER" or "FRIDAY FORECAST" as text. But the video has those labels, but according to the rules, we must exclude text recognition. So we can just say "the map displays current weather" without the text. Wait, the rules say: "Exclude text recognition, named characters, or stylistic analysis." So "CURRENT WEATHER" is text, so we don't mention it. But the map is a weather map, so we can say "the map shows current weather patterns" without the text label.

Wait, but the task says "Focus primarily on the motion and behavior of main subjects (people/animals/objects) in chronological order." So the main subject is the person, then the map changes. The map's content is an object, so describe the map's change. But since text recognition is excluded, we don't reference the text labels, just the visual elements.

So revised: A person in a dark suit stands to the right of a U.S. weather map, gesturing with their hands. The map then transitions to a Colorado-focused view, displaying temperature markers across the region. The camera remains static, focusing on the map and the person’s hand movements.

Check if spatial relationships are mentioned: person is to the right of the map. Yes. Motion: person gestures, map transitions. Chronological order: first person with US map, then map changes to Colorado. Camera: static. Background is minimal (just the map).

Another check: "A person in a dark suit gestures with their hands while standing to the right of a U.S. weather map. The map then changes to a Colorado forecast view, showing temperature markers for specific locations. The camera maintains a static position throughout, focusing on the map and the person's movements."

Yes, that's concise. Make sure to include chronological order: first the person with US map, then map transitions. Mention the person's appearance (

The weather presenter (a solid object) moves with hand gestures and body shifts, indicating locomotion due to physical forces (e.g., muscle movement).

The background (US map) is static with no shifting. No fluid/environmental motion (fire, water, wind) observed.


RAW CAPTION: Got it, let's break down the video. First, the scene is a baseball field behind a chain-link fence. In the first frame, there's a boy in a green and white uniform (maybe a batter or runner) near home plate, a person in red (maybe a coach) standing, and an umpire in a light blue shirt walking. Then in the next frames, the boy runs towards first base, the person in red moves towards the infield, another kid in red runs towards the base. The umpire walks along the fence line. So chronologically: the boy starts at home, runs to first, the red-shirted person follows, another kid runs, and the umpire moves. Spatially, the umpire is in front of the fence, the players on the field. Background has trees, but minimal. Camera is behind the fence, maybe panning slightly as the umpire walks. Let's condense.

Main subjects: several players (kids in red and white uniforms, one in green), umpire. Actions: boy runs towards first base, others move. Umpire walks. Need to mention their appearances briefly. Number: at least two kids in red, one in green, umpire. Spatial: umpire in front of fence, players on field.

Chronological order: The video opens with a boy in a green and white uniform standing near home plate, while a person in a red shirt and dark shorts stands on the infield dirt. A man in a light blue shirt and dark pants walks toward the fence. Subsequently, the boy runs toward first base, the red-shirted individual moves toward the infield, and another child in a red shirt sprints toward the base. The umpire continues walking along the fence line as the players move across the field. The camera remains stationary behind the chain-link fence, capturing the action from a fixed perspective.

Check rules: focus on motion and behavior chronologically. Appearance (color, size, orientation) – but keep brief. "Several children in red and white uniforms, one in green, and an umpire in light blue shirt and dark pants" – but maybe too much. Wait, rules say "briefly describe appearance and number". So: a boy in green and white uniform (1), person in red shirt (1), umpire in light blue (1), another child in red (1). Then motion: boy runs to first base; red-shirted person moves toward infield; second child runs to base; umpire walks. Background minimal, mention trees as backdrop. Camera: behind fence, stationary? Or does it pan? In the video, the umpire moves, so camera might pan slightly. The frames show the view shifting, so maybe slight pan right as the umpire walks.

Wait, original frames: [0.0] shows a boy in green near home, person in red, umpire. [1.0] maybe the boy runs, then [2] another kid in red runs. The camera seems to follow the umpire's movement slightly, so maybe pan left or right. But the description should be concise.

Let me try a draft:

The video depicts a youth baseball game viewed from behind a chain-link fence. Initially, a boy in a green and white uniform stands near home plate while a person in a red shirt and dark shorts stands on the infield dirt. A man in a light blue shirt and dark pants walks toward the fence. Shortly after, the boy runs toward first base, the red-shirted individual moves toward the infield, and another child in a red shirt sprints toward the base. The umpire continues walking along the fence line. The camera remains fixed behind the fence, capturing the players' movements on the field.

Check for brevity. Let's cut some details. "Youth baseball game" maybe not necessary. Focus on main subjects.

"Several children in red and white uniforms and one in green; an umpire in light blue shirt. The boy in green runs toward first base, the red-shirted person moves, another red-shirted child sprints. Umpire walks along fence."

Wait, need chronological order. First, the boy (green) is near home plate, then runs to first. Red-shirted person is on infield dirt, moves. Another kid runs. Umpire walks.

Make it a paragraph.

"The video begins with a boy in a green and white uniform standing near home plate, a person in a red shirt and dark shorts on the infield dirt, and an umpire in a light blue shirt walking toward the fence. The boy then runs toward first base while the red-shirted individual moves toward the infield. Another child in a red shirt sprints toward the base. The umpire continues walking along the fence line. The camera stays behind the chain-link fence, capturing the players' movements with minimal background details."

Check rules: a) motion chronological – yes

The runner (in white) runs from first base to second base, the pitcher (in gray) throws the ball, the batter (in red) hits the ball, and the baseball moves through the air. These motions are due to physical forces (locomotion, collision).

The background (chain-link fence, trees) is static with no significant fluid or wind motion. No fire, water, or smoke is present.


A person wearing a camouflage-patterned shirt and dark pants stands in front of white louvered doors, holding a megaphone in the left hand and a bottle in the right, moving the bottle while gesturing toward the megaphone. A colorful hanging item is visible to the right. The camera remains stationary throughout.

A person (boy) holding a megaphone moves their hand to bring the megaphone to their mouth and away; discrete solid object motion due to explicit muscle-driven locomotion.

Background (white closet doors and colorful wall hanging) remains stationary throughout; no fluid or environmental motion (fire, water, smoke, wind) observed.


A man in a red and black plaid shirt holds a black microphone, moving it from his mouth to his chin and back up in front of him while looking directly at the camera; the static camera captures his upper body against a backdrop of bookshelves and wooden cabinets.

The man (a solid distinct object) is moving his head and mouth as he speaks.

The background (bookshelf, clothes) is static with no shifting, and there are no ambient environmental elements (fire, water, smoke, wind).


A person in a red shirt and black pants emerges from behind a white couch, steps forward, and walks past it, moving toward the right edge of the frame. The camera remains stationary.

A person (wearing red shirt and black pants) emerges from behind a white sofa and walks around it.

No shifting background or fluid/environmental motion observed; background elements (walls, floor, furniture) are static.


RAW CAPTION: Got it, let's break this down. The video shows a close-up of an eye makeup application process. First, there's a split-screen showing the upper eye being worked on with a brush. The brush has a pink handle and blue tip. Then, the next frames show the same eye with different steps: applying eyeliner, maybe, then a black brush near the lower lash line. Then a hand with a blue and black nail polish applies something. Wait, the video is split into two rows, top and bottom. Each frame is a split-screen, so the top part shows one action, bottom another. Let's sequence the actions chronologically.

First frame: top and bottom show a brush (pink handle, blue tip) applying makeup to the upper eyelid. Then next frame: top part shows a black eyeliner being applied to the upper lid, bottom part shows the same? Wait, no. Wait the video is a series of split-screen frames. Let's parse each frame.

Frame 0: top is eye with copper glitter on upper lid, brush (pink handle, blue tip) is touching the eye. Bottom same but maybe slightly different angle.

Frame 1: top is eye with makeup, a black dot (maybe a pencil) applied near the eye. Bottom shows a different action? Wait, no, the split screen is two parts: top and bottom. So for each timestamp, there's a top and bottom panel.

Wait the description says: [0.3s] top and bottom show a brush with pink handle (blue tip) applying makeup. Then [1.4s] top shows a black dot near the eye (maybe eyeliner), bottom shows the same eye. Then [2.5s] top and bottom show the eye with brown hair, the brush is near the lower lid. [3.6s] top and bottom show a black brush (maybe mascara wand) near the eyelashes. [4.7s] top and bottom show a hand with blue and black nails applying something (maybe eyeliner or shadow).

Wait, the user is describing the video as split-screen. So the main subject is the eye, with makeup application steps. The key is to list the chronological actions.

First action: brush with pink handle (blue tip) applies product to upper eyelid (copper shade). Then, applying a dark eyeliner (black) to the upper lid. Then, using a black brush (mascara wand) on lower lashes. Then, a hand with blue/black nails (nail polish) applies product, maybe eyeliner to lower lash line.

Wait, need to check the video. The user provided the video frames. Let's list the steps:

- Start: split screen, top and bottom show a brush (pink handle, blue tip) applying copper eyeshadow to the upper eyelid. The eye has a white patch (tape maybe) under the eye.

- Then, the top part shows a black eyeliner being applied (a small dot, maybe lining the upper lid), the bottom part shows a different angle.

- Next, the top shows the eye with brown hair framing it, and a black brush (mascara) is near the lower lashes. Bottom is similar.

- Then, top shows a black brush (mascara wand) applying product to lower lashes. Bottom similar.

- Then, top and bottom show a hand with blue and black nail polish (nail design) applying product (maybe eyeliner to lower lash line).

Now, the caption needs to be chronological. So:

The video shows a close-up of an eye makeup application process. A pink-handled brush with a blue tip applies copper eyeshadow to the upper eyelid. Then, a black eyeliner pencil is used to outline the upper lash line. Next, a black mascara wand is applied to the lower lashes. Finally, a hand with blue and black nail polish applies eyeliner to the lower lash line. The camera remains in a split-screen view throughout, focusing closely on the eye and application tools.

Check rules: a) motion chronological. b) appearance of tools: pink handle blue tip brush, black eyeliner pencil, black mascara wand, hand with blue/black nails. c) spatial: tools in front of the eye. d) camera: split-screen, close-up. e) background minimal. f) no text.

Let me structure:

Start: brush applies copper shadow to upper lid.

Then, eyeliner is applied to upper lid.

Then, mascara wand to lower lashes.

Then, hand with blue/black nails applies lower eyeliner.

Camera split-screen, close-up.

Make it concise.

Final caption:

The video shows a split-screen close-up of eye makeup application. A pink-handled brush with a blue tip applies copper eyeshadow to the upper eyelid. Next, a black eyeliner pencil outlines the upper lash line. Then, a black

The makeup brush is the discrete object moving to apply makeup on the eye, with controlled motion due to human manipulation.

No shifting background elements; no fire, water, or wind detected. The background (person's face and hair) is static.


A baby in a white outfit is held by an adult and holds a bubble toy. A boy in a blue shirt and red shorts walks into the frame from the left, holding a bubble wand. The baby turns to look at the boy as he passes, then turns back toward the camera. The camera remains close to the baby with a slight shake.

The baby (held by an adult) exhibits subtle movement while holding a bouquet, and a person in a blue shirt walks in the background. The bouquet's motion is linked to the baby's hand movements, and the walking person's motion is due to locomotion.

Background elements (grass, trees, distant structures) show minimal shifting; no fire, water, smoke, or significant wind-driven motion observed. Static elements remain largely stable across frames.


A person's right hand rests on a purple table with a yellow utility knife to the left, a floral-patterned card (pink flowers, green stems) in center, and a white cup to the right. The left hand enters from the top, places over the card, and the right hand moves left. Both hands adjust the floral card, positioning it flat on the table. The camera maintains a top-down view with no movement throughout.

A person's hands are actively moving a small printed card on the table surface, exhibiting distinct physical interaction (shuffling, positioning).

The purple table surface, yellow utility tool, white cup, and background elements show no shifting or fluid motion; no fire, water, smoke, or wind is present.


Two muscular men in black sleeveless tops and blue shorts stand side by side in a gym, initially bent forward with arms extended toward their knees. They simultaneously straighten their upper bodies, lifting their arms upward to raise them overhead. The camera remains stationary, capturing their synchronized movement from a fixed perspective.

Two people are moving: one in the foreground performing pull-ups (arm motion with bar) and one in the background exercising with a cable machine (arm motion). Both exhibit clear locomotion due to muscular effort.

The gym background (walls, equipment, floor) shows no shifting or fluid motion; no fire, water, smoke, or wind are present. Static elements remain fixed throughout.


A person wearing a black shirt and blue pants sits on grass, bends forward, and dips hands into a red bucket. They then transfer a small white object from the red bucket to a gray bucket positioned to the left. The camera shifts to a close-up view of the buckets and hands throughout the sequence.

The person's hands interact with eggs and buckets, moving objects (eggs) between containers. Solid objects (eggs, hands, buckets) exhibit explicit physical motion due to manual manipulation.

The grassy background and fence remain static with no significant fluid or environmental motion (fire, water flow, smoke, wind). No uniform shifting of background elements indicates no camera-induced motion.


A person in a green shirt, white shorts, and green socks swings a hurley stick to strike a ball, which is propelled forward after contact; the player follows through with the swing while maintaining a balanced stance. The camera captures the action from a fixed position.

A person (hurling player) in motion using a hurley to strike a sliotar (ball). The ball's trajectory and the player's body movements represent discrete, solid object interactions.

Background elements (banners, grass field) are stable with no uniform shifting or fluid environmental motion (fire, water, smoke, wind).


A young child with messy hair, wearing a brown and blue striped shirt, sits in a white high chair with food residue on their face. The child smiles broadly, moves their right hand upward, and gradually turns their head left before returning to center. The camera maintains a close-up perspective with slight handheld shake, focusing on the child’s facial expressions against a blurred kitchen background.

The child (a solid object) exhibits subtle head movements, facial expressions, and hand motion, all attributable to self-generated locomotion and expression.

Background elements (countertop, bottles) remain static with no uniform shifting or fluid motion. No fire, water, smoke, or wind detected.


A hand with bright red nail polish uses pink tweezers to adjust the upper eyelashes of an eye with shimmery purple eyeshadow, followed by the hand pressing near the eyelid area to refine the makeup application. The camera maintains a close-up perspective, focusing exclusively on the eye and hand movements with minimal background detail.

The hand (with red nails) and tweezers are moving to manipulate the eyelashes. The eyelashes are also moving due to the application.

The background (skin and eyebrow) is static; no fluid or environmental motion (fire, water, wind) is present.


The video opens with a blurred outdoor scene featuring vehicles. It transitions to a clearer shot where two men—one in a white shirt and dark pants, the other in a light shirt—bend over near a blue car on a paved area, interacting with an object on the ground. Additional people in blue shirts stand nearby. The camera maintains a ground-level perspective with a slight shake throughout, capturing the scene as the men move slightly while focused on their actions.

Multiple solid objects (people) exhibit discrete motion: individuals are bending, lifting, and moving a person on the ground. These actions involve locomotion and physical interaction, with distinct bounding boxes tracking individual movements.

Background elements (trees, parked cars) remain stationary and do not shift uniformly across frames. No environmental phenomena (fire, water, wind) are present; the scene is static with clear background objects.


Two individuals interact with a yellow cloth; the person in a black shirt with a star logo manipulates the cloth vertically while the person in a peach shirt with a heart design holds it. Their hands move the cloth in a vertical motion, with the black-shirted individual pressing and adjusting it. The camera maintains a close-up perspective, slightly shaky, focusing on the hands and cloth as they shift positions.

Briefly describe what discrete, solid objects are moving.

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


A person in a white shirt holds a white, fluffy kitten upright in a sink, scrubbing its body with a blue brush. The kitten remains in the sink, facing upward as the person adjusts its position and continues cleaning. The camera captures the scene from a close-up, slightly shaky perspective, focusing on the washing action.

The person (white shirt) manipulates the cat's body with hands, causing the cat to move (limbs, head shifts) and splash water. Both the person's hands/arms and the cat are distinct solid objects moving under explicit physical forces (washing action).

The sink background (counter, bottles, faucet) remains static throughout. Water in the sink is splashing due to washing but is contained and secondary to the discrete object motion; no fire, smoke, or large-scale environmental fluid dynamics are present.


Two individuals, one wearing a blue cap and gray shirt, the other in a gray shirt, work at a table in a workshop. The first uses a block to smooth a wooden plank while the second holds a cloth; the camera zooms in on their hands and the wood as they smooth it, then pulls back to show both at the table.

Two individuals sanding a wooden board; their hands and sanding blocks move in discrete motions to smooth the wood.

Background elements (shelves, tools, chair) are static; no fluid/environmental motion (fire, water, smoke, wind) detected.


A man in a red sleeveless shirt and black shorts stands in a gym, bends into a squat, stands upright, then walks left and exits the frame. The camera maintains a low-angle, static perspective.

The person in a red shirt and black shorts is moving: walking towards the camera and then away. This is a discrete, solid object moving due to locomotion.

The background (gym equipment, walls, floor) is static and shows no shifting or environmental motion (e.g., fire, water, smoke, wind).


A person wearing a red shirt, black shorts, and black shoes stands on a track with orange cones arranged in front. They lift a ball to shoulder height, swing their arm backward, and release the ball, which arcs through the air as they follow through with their body. The camera remains static, capturing the motion from a frontal perspective with minimal background details.

The person (red shirt, black shorts) and the ball are discrete solid objects. The person moves via locomotion (walking, jumping) while throwing the ball, which travels through the air under gravity.

The background (parking lot, trees, buildings) remains static with no shifting or fluid motion. No fire, water, smoke, or wind-driven phenomena are present.


A pair of hands uses a knife to slice a red apple on a green cutting board, first cutting straight down 3/4 inch parallel to the edge, then flipping the apple to make a parallel cut matching the first slice, with apple pieces arranged on the board and a plate containing banana and green fruit visible in the background. The camera maintains a static close-up view of the cutting process.

The hands, knife, and avocado pieces are moving due to the cutting action. The hands manipulate the knife to slice the avocado, with pieces being repositioned during the cut.

The background (countertop, plate with greens) is static and shows no fluid or environmental motion. No uniform background shift detected.


A girl in a pink shirt holds a frying pan, swings it downward, bends forward, and opens a white cooler to her right. The concrete floor and miscellaneous items form the background as the camera follows her movements with a slight shake.

The child (discrete object) moves the wooden spoon through deliberate motions (swinging, lowering) and interacts with a box (opening, bending over). All movements are driven by the child's physical actions.

The background (concrete floor, blue trash can, white tarps) shows no uniform shifting or fluid motion. No fire, water, smoke, or wind is present.


A boy in green clothing adjusts the handlebars of a bicycle, then begins pedaling forward and exits the frame to the left. The background includes a brick wall with square cutouts, a white fence, and rocks with plants. The camera remains stationary, capturing the boy’s movement from center to left as he leaves the frame.

The person and the bicycle are discrete solid objects moving due to explicit human action (adjusting, positioning the bike).

The static background (lattice wall, rocks, plants) shows no uniform shifting or fluid motion; no fire, water, or wind is present.


A person wearing a camouflage jacket and black shirt uses blue scissors to cut a light blue paper strip on a wooden table. After cutting, they lift the paper, hold it up to examine, and begin folding or manipulating it with both hands. The table shows scattered debris, including small white and yellow fragments. The camera maintains a top-down perspective with no significant movement throughout the sequence.

Discrete solid objects (hands, blue scissors, light blue plastic bag) exhibit motion from explicit physical actions (cutting, manipulating the bag).

The wooden table and background elements (chairs, shelves) remain static with no uniform shifting; no fire, water, smoke, or wind dominates the scene.


A person in a dark jacket and white gloves holds a cue stick, positioning it near red and white pool balls on a green table; they adjust the cue stick, then strike the balls, causing them to scatter across the table; the camera shifts slightly to reveal more of the pool room with additional tables, while remaining focused on the main action.

The pool balls (cue ball and object balls) are moving due to collision with the cue stick. The cue stick is moved by the player.

No fire, water, smoke, or wind. Background elements (walls, furniture) show minimal shifting due to camera movement but not uniform and not dominant.


RAW CAPTION: Got it, let's break down the video. The main subject is a person walking on stilts. First, in the initial frame, they're on a grassy area near a sidewalk. They're wearing a light-colored shirt and dark pants, with stilts on their feet. The person starts walking forward, moving from the sidewalk onto the grass. As they go, their arms are out for balance. Then they turn slightly, maybe to adjust direction. The background has trees, a fence, and some orange cones, but we don't need to describe too much. The camera is following the person's movement, probably a steady follow shot. Let's make sure to capture the chronological order: starting position, walking motion, turning, and then moving out of frame. Also, check the rules: focus on motion, appearance briefly, spatial relationships if relevant. The person is moving from right to left across the frame? Wait, in the frames, the person is moving towards the camera initially? Wait, first frame: person is on grass, near sidewalk. Then they walk forward, moving across the grass. The camera seems to follow them. Let's see: the video starts with the person walking towards the camera, then moves to the right, turns left, and exits the frame. Wait, in frame 0, they're in the middle, then frame 1 they're moving right, frame 2 they're further right, frame 3 they're turning, frame 4 they're moving left, and frame 5 they're exiting the left. So the path is from right to left, then turning. Wait, maybe the person is walking in a straight line, then turning. Let's structure the caption: A person wearing a light-colored shirt and dark pants walks on metal stilts across a grassy area, moving from right to left while adjusting their balance with outstretched arms; the person turns slightly to the left and continues moving leftward, exiting the frame. The camera follows the person's movement, maintaining a steady perspective with slight camera shake. Wait, need to check the camera movement. The description says "slight shake" but maybe not. The rule says "conclude with camera perspective and movement". Let's check the video: the camera seems to follow the person, so it's a tracking shot. But in the given frames, the camera angle might be steady. Wait, the problem says "keep background minimal", so focus on the person's motion. Let's make it concise. The main points: person walking on stilts, light shirt, dark pants, moving across grass, turning, camera follows. So: A person in a light-colored t-shirt and dark pants walks on metal stilts across a grassy area, moving from right to left while balancing with arms extended; the person turns left and continues moving leftward, eventually exiting the frame. The camera maintains a steady follow shot with slight shake. Wait, but maybe the camera isn't shaking. The problem says "conclude with camera perspective and movement". Let's see, the video's camera is moving to follow the person, so it's a following camera. So: A person wearing a light-colored t-shirt and dark pants walks on metal stilts across a grassy area, moving from right to left while extending their arms for balance; the individual turns slightly left and continues moving leftward, exiting the frame. The camera follows the subject with a steady perspective. Wait, but the rules say "briefly describe appearance and number". The person is singular. So: A person in a light-colored shirt and dark pants walks on metal stilts across a grassy area, moving from right to left while extending their arms for balance; they turn left and continue moving leftward, exiting the frame. The camera follows the subject with a steady shot. But need to check chronology. Let's list the frames: 0 - person is on grass, near sidewalk. 1 - person moves forward, still on grass. 2 - person is moving more, arms extended. 3 - person turns, maybe to the left. 4 - person moves left, exiting. So the order is: starts walking forward, then turns left, then moves left. Wait, frame 0: person is facing slightly left, then frame 1: moving forward, arms out. Frame 2: moving more, maybe turning. Frame 3: turning left. Frame 4: moving left, arms down. Frame 5: exiting left. So the person starts walking towards the camera, then turns left, and continues moving left. So the motion is: walking forward, then turning left, moving leftward. So caption: A person in a light-colored t-shirt and dark pants walks on metal stilts across a grassy area, moving forward while extending arms for balance; the individual turns left and continues moving leftward, exiting the frame. The camera follows

A person wearing a white t-shirt and black pants is walking on stilts across the grassy area.

The background (trees, grass, pathway) remains stationary without any noticeable shifting or environmental fluid motion (fire, water, smoke).


tags. Make sure to not include any extra text.  Final check: concise, chronological, covers main actions, appearances, camera movement. Yes. </think>  <caption_output>A doctor in a white coat with a stethoscope converses with an older woman in a green shirt in a clinic. Next, a man in a hospital gown stands as a doctor in a blue shirt examines his back in a medical room. Finally, a woman in a white puffy coat and pink scarf walks through a crowded street, with the camera following her movement.

People in the street scene are moving due to locomotion (walking); individuals in the doctor's office and hospital room exhibit subtle body movements during conversation.

Background elements (walls, clock, hospital cabinets, street buildings) show no shifting or fluid motion; no fire, water, smoke, or wind visible.


A person in a light blue shirt walks from the right side of the frame toward the bar counter, passing behind it. A person in a white shirt stands at the bar, while another individual in a red shirt sits on the left side of the frame. The camera remains in a top-down position with minimal movement.

Multiple people (bartenders and patrons) are moving: one bartender walks between bar stations, serves drinks, and interacts with customers; others move in the background. These are discrete solid objects exhibiting locomotion and physical interactions.

Background elements (walls, shelves, ceiling) remain stable with no uniform shifting. No fire, water, smoke, or wind motion is observed; the environment is static.


A young blonde child wearing a red Mickey Mouse shirt moves toward a mirror, turns around, and reaches out to touch the mirror surface, then interacts with the reflection by moving their hands. The camera follows the child’s movements closely with slight shake, capturing the interaction against a patterned carpet and mirrored wall.

Two children in red shirts interact with a mirror; one child moves toward and touches the mirror, while the reflected image of the other child shifts in response to movement.

Static room background with walls and patterned floor; no shifting backgrounds or fluid/environmental motion (fire, water, wind) detected.


A toddler wearing a white sleeveless shirt with colorful graphics and dark shorts sits on a playground swing, gripping a yellow bar. The child initially looks downward, then turns their head to the right while scanning the surroundings. The background features a dirt ground and scattered trees. The camera remains close, capturing slight motion as it follows the child’s movements.

The child and the swing are moving back and forth due to the child's physical actions (swinging).

The background (trees, ground) is static with no fluid or environmental motion (fire, water, smoke, wind) dominating the scene. The motion of the child on the swing is subtle but present.


A person in a white and black striped hoodie and dark pants runs across a grassy area, jumps with legs extended, turns toward the hedge, and continues running. The camera remains stationary, capturing the motion against a dense green hedge backdrop.

A person (solid, distinct object) is performing a dance routine, moving in place with leg lifts and arm motions. The motion is due to locomotion of the person.

The background (hedge and grass) shows no significant shifting or fluid motion. The hedge is dense and static, with no visible wind-induced sway. There are no elements of fire, water, or smoke.


RAW CAPTION: Okay, let's tackle this video captioning task. First, I need to understand what the user wants. They provided a video clip and specific rules for creating a caption. Let me read through the rules again carefully.

The main goal is to generate a concise, chronological paragraph describing the video. The key points from the rules are: focus on motion and behavior of main subjects in order, mention appearance and number (color, size, orientation), spatial relationships if relevant, conclude with camera perspective and movement, keep background minimal, exclude text recognition, named characters, or stylistic analysis.

Looking at the video description: it's a scene with a child in a red-tinted environment, likely a restaurant or event. The child is clapping, then a woman hands them something. The background has other people, but we shouldn't focus too much on that.

First, identify the main subjects. The child is the main subject. Then the woman handing something. Let's break down the timeline.

In frame 0: The child is sitting, clapping. The video starts with the child holding hands, maybe a cup or something. Wait, the description says "clapping" in the first part. Then in frame 1-3, the child claps their hands. Then frame 4, a woman's hand comes in with a cup or container. Frame 5, the child takes it.

So chronological order: child claps, then woman gives something, child takes it.

Appearance: child is small, wearing a white and red outfit. The woman is an adult, maybe in a black dress. The background has other people, but minimal.

Spatial relationships: the woman approaches from the left, gives the object to the child. The child is seated, facing the camera.

Camera perspective: The video seems to be shot from a medium angle, maybe slightly tilted. The description mentions the camera movement as "slight shake" but the user's example in the output format says to mention it if relevant. Wait, the user's example doesn't have that, but in the rules, d) says to conclude with camera perspective and movement. So need to check if there's any camera movement. The original video description doesn't specify, but since it's a short clip, maybe it's static or has a slight shake. The user's example might not have it, but the instruction says to include if relevant.

But the problem is, the user's example in the rules shows to include camera perspective. Let me check the rules again. Rule d: Conclude with the camera perspective and movement. So even if it's static, maybe say "static camera" or "slight shake".

Looking at the video description: the frames show the child in the foreground, with people behind. The camera angle is probably eye-level, since it's focusing on the child. The movement: the frames transition smoothly, so maybe no significant movement, but perhaps a slight shake as per the description.

Wait, the user's instruction says "Keep background descriptions minimal unless essential for understanding motion." The background has other people but not crucial for motion.

Now, structuring the caption:

Start with the main subject's actions in order.

1. The child (small, wearing white and red outfit) claps hands while seated.

2. A woman (adult, black dress) enters frame from the left, offers a cup/container to the child.

3. Child takes the cup.

Then, mention the background: other people seated, but minimal.

Camera: static or slight shake.

Wait, the original frames might not have significant movement, but the user's example in the rules might not have that, but according to rule d, we must include camera perspective and movement. So need to figure out.

In the given video frames, the camera seems to be stationary, focused on the child. Maybe "static camera" or "fixed perspective".

Wait, the first frame is [0.0], so the camera is fixed. The movement might be minimal, so perhaps "static camera".

Now, assembling the caption:

"A small child wearing a white and red outfit sits, clapping hands together. An adult woman in a black dress approaches from the left, extending a cup to the child, who then takes it. The child remains seated as the woman withdraws. Other people are visible in the background, seated at tables. The camera maintains a static perspective throughout."

Wait, but the rules say to exclude text recognition, named characters, etc. So no mention of "black dress" if it's not necessary? Wait, rule b says "Briefly describe their appearance and number (color, size, orientation)." So the woman's dress color is part of her appearance. So including "black dress" is okay as it's part of her appearance.

Wait, the woman's dress is black, so "an adult woman in a black dress" is acceptable.

But the problem is

A child's hands clapping and eating, with a hand feeding the child—discrete human movements due to physical interactions.

Background elements (people, tables) show minimal uniform shift; no fire, water, smoke, or wind motion detected.


A hand sprinkles sliced red roasted peppers onto a pizza topped with halved red tomatoes and black olives. Then, another hand adds shredded white mozzarella cheese over the pizza. The camera maintains a close-up, static view of the pizza during the topping additions.

A hand (discrete solid object) moves to sprinkle roasted red peppers and mozzarella cheese onto the pizza. The cheese particles move under gravity after being added but are driven by the hand's action.

The grill background remains static with no shifting elements or environmental motion (fire, water, smoke, wind). The only motion is the hand adding ingredients.


Two children sit on a black leather couch; the child on the left, wearing a red shirt, holds a white bowl and eats using a spoon, while the child on the right, in a white shirt with colored stripes, focuses on a colorful puzzle on a table in front of them. The left child continues eating, and the right child manipulates puzzle pieces. The camera provides a top-down view with slight movement.

Two children exhibit discrete movements: the child in red shirt raises hand, brings food to mouth, and chews; the child in white shirt interacts with a book (touching pages, shifting gaze).

No fire, water, smoke, or wind present. Background (couch and wall) is static with no shifting elements.


RAW CAPTION: Got it, let's break this down. The video shows a birthday scene. First, there's a child in a teal shirt standing at a table with a cake. Another child in a striped shirt and green headband is next to him. An adult on the left is holding the first child, maybe supporting them. Then, someone on the right (another adult) is lighting candles on the cake. The candles go from a few to more as they light them. The kids are watching, maybe the one in teal is holding a knife. The cake is white with decorations. The background has a restaurant setting with booths and windows. The camera is steady, maybe slightly handheld. Need to describe chronologically: first, the setup, then the lighting of candles, then the kids' reactions. Keep it concise, mention appearances (teal shirt, striped, green headband), spatial (left, right), motions (lighting candles, holding knife). No text, no names.

Let me structure:

- Start with the group: two children (one in teal shirt, one in striped shirt with green headband), an adult on left holding the striped child, another adult on right lighting candles. The cake is on the table, white with sprinkles.

- Then, the right adult lights candles, increasing from a few to more.

- The kids watch, the teal-shirt child holds a knife (maybe for cutting later).

- Camera is stable, slight shake maybe.

Now, make sure to follow rules: chronological, focus on motion, appearance, spatial, conclude camera. Keep minimal background.

Draft: In a restaurant setting, a boy in a teal shirt and a girl in a black-and-white striped shirt with a green headband stand at a table; an adult on the left supports the girl, while another adult on the right lights multiple candles on a white-frosted cake with colorful sprinkles. The boy holds a knife near the cake as the candles ignite, and both children observe the process. The camera remains mostly stationary with a slight shake.

Check rules:

a) Motion: lighting candles, holding knife, observing.

b) Appearance: teal shirt, striped, green headband, white cake, sprinkles.

c) Spatial: left adult supports girl, right adult lights candles, boy in front of cake.

d) Camera: stationary, slight shake.

e) Background: minimal (restaurant, but only if essential; since it's setting, maybe mention "restaurant" as context).

f) Excluded text, names.

Yes, that's good. Let's tighten:

In a restaurant, a boy in a teal shirt and a girl in a black-and-white striped shirt with a green headband stand at a table; an adult on the left holds the girl, while another adult on the right lights multiple candles on a white-frosted cake with sprinkles. The boy holds a knife near the cake as the candles are lit, and both children watch. The camera remains stationary with a slight shake.

Wait, "holds the girl" – in the video, the adult is holding her, maybe "supports" but "holds" is okay. "Lights multiple candles" – as they light them, so the action is lighting candles. Also, the girl might be leaning on the table. Let's check the frames: in frame 0, adult left is holding the girl's hand maybe? Wait, frame 0: adult left, girl, boy, cake. Frame 1: adult left holding girl's hand, boy holding knife. Frame 2: girl is leaning, adult right lighting. So the adult on left is holding the girl, supporting her. The boy has a knife in his hand, ready to cut? But in the video, the action is lighting candles first.

So:

A child in a teal shirt and a child in a black-and-white striped shirt with a green headband stand at a table; an adult to the left holds the striped-shirt child, while an adult to the right lights candles on a white-frosted cake with colorful sprinkles. The teal-shirt child holds a knife near the cake as the candles are ignited, and both children observe. The camera remains stationary with minimal movement.

Wait, the problem says "concise", so maybe shorten:

At a table in a restaurant, a boy in a teal shirt and a girl in a striped shirt with a green headband stand; an adult to the left supports the girl, while another adult to the right lights multiple candles on a white cake with sprinkles. The boy holds a knife near the cake as the candles ignite, and both children watch. The camera stays steady with slight shake.

Yes, that's better. Let's check if it's chronological: first, the setup (people standing), then lighting candles, then the boy holding knife (maybe as part of the process), children watching.

I think that's covered.
</think>

<caption_output>In

Children and adults seated at a table: the girl in the striped shirt shifts posture and leans forward, the boy in blue shirt moves his head slightly, and the man on the right adjusts his hand position. All movements are small, discrete, and consistent with human locomotion.

The background consists of static interior elements (wooden furniture, walls) showing no uniform shifting. Candle flames exhibit minor flickering, but this is not dominant motion; ambient fluid motion is minimal and localized.


RAW CAPTION: Got it, let's break down the video. First, the scene shows two people windsurfing on a lake with mountains in the background. The main subjects are the windsurfers. Let's check the sequence.

In the first frame, there are two windsurfers: one with a transparent sail (orange frame, sail has "G" maybe?) and another with a red sail. The water is calm, mountains in the distance. Then, the camera seems to zoom in or move closer to the first windsurfer. By frame 2-3, we see a person on the transparent sail board. Then frame 3-4, the person is standing up, holding the sail. The other windsurfer with red sail is in the background, moving. The person on the transparent sail is in the foreground, wearing a black vest and white shorts. The background has mountains and a few other people in the distance.

So chronological order: two windsurfers on the water. The main one is in front (transparent sail, orange frame), then the camera moves closer to show them standing up, holding the sail. The other windsurfer with red sail is behind. The camera movement is likely panning or zooming in from a distance to a closer view. Background is mountains, minimal.

Now, follow the rules: motion, behavior, appearance, spatial relationships, camera perspective.

First, describe the initial state: two windsurfers on a lake. One with transparent sail (orange frame, white board with black patterns), other with red sail. Then camera focuses on the first person, who is standing up, holding the sail. The person in the foreground is wearing black vest and white shorts, moving with the wind. The red-sailed windsurfer is in the background, also moving. Then the camera shifts to a closer view of the foreground windsurfer, showing them balancing.

Wait, the video starts with both windsurfers, then the camera moves to focus on the one with the transparent sail. So the chronological order:

- Initial scene: two windsurfers on calm water, mountains in background. One (foreground) has transparent sail with orange frame, white board with black pattern; other (background) has red sail, white board. Both are moving across the water.

- As the video progresses, the camera zooms in on the foreground windsurfer, who stands upright, holding the sail's control, balancing on the board. The background windsurfer remains visible but is less prominent.

- The foreground windsurfer's movements include adjusting their stance to maintain balance as they glide on the water.

- Camera perspective shifts from a wider shot to a closer view of the main windsurfer, with slight movement to follow their motion.

Background: mountains, minimal description. Exclude text recognition (so no "G" or numbers on the sail, just color).

So structure the caption:

Two windsurfers glide across calm water with mountains in the distance. The foreground windsurfer, wearing a black vest and white shorts, stands on a white board with black patterns, holding a transparent sail with an orange frame. A second windsurfer with a red sail is visible in the background, also moving across the water. As the video progresses, the camera zooms in on the foreground windsurfer, who adjusts their stance to maintain balance, while the background windsurfer remains slightly out of focus. The camera moves from a wide shot to a closer perspective, following the motion of the main windsurfer.

Check rules: a) motion chronological: start with both, then focus on foreground. b) appearance: colors, size, orientation. c) spatial: foreground, background. d) camera: zoom in, follow motion. e) background minimal. f) exclude text. g) no reasoning.

Wait, in the video, the first few frames show both windsurfers, then the camera moves closer to the one with the transparent sail. So the main subject is the foreground windsurfer. Let's make sure to capture the sequence.

First, the video shows two windsurfers. Then the camera focuses on the main one, who is standing up (from the initial position maybe? But the frames show them standing). Wait, the first frame: two windsurfers. Then frame 2-3: the camera is closer, and the person is standing. So the motion is the camera moving to the foreground windsurfer, who is standing.

So the caption:

Two windsurfers navigate calm waters with mountainous terrain in the background. The foreground windsurfer, dressed in a black vest and light shorts, balances on a white board with black patterns while holding a transparent sail with an orange frame; the second windsurfer, with a red sail, remains visible in the distance. As the video progresses, the camera zooms in on the foreground windsurfer, capturing their adjustments to maintain

Two windsurfers on boards with sails are actively moving across the water. Their motion is driven by wind, sail manipulation, and physical locomotion.

Background elements (mountains, distant shore) show no uniform shifting. Water ripples are present but not dominant; environmental motion is secondary to object movement.


Two players, one in a blue shirt and one in an orange shirt, engage in a squash match on a wooden court enclosed by glass walls. The blue-shirted player initiates a forward swing toward the front wall, then moves to the right side as the orange-shirted player advances to intercept the ball, turning to face the front wall. The blue player follows, adjusting position to continue the rally, while the orange player shifts toward the left side of the court. Both players maintain active stances, holding rackets, with minimal background detail visible beyond the court's boundaries. The camera remains fixed, capturing the action through the glass enclosure.

Two squash players (solid, distinct objects) and a squash ball (solid, distinct object) are moving. Players execute swings, lunges, and repositioning; the ball is struck and travels between players.

The background (walls, floor, court markings) shows no shifting or fluid motion. No fire, water, smoke, or wind is present.


RAW CAPTION: Okay, let's tackle this video captioning task. So, the user provided a video clip and wants a concise chronological paragraph following specific rules. First, I need to understand the video content.

Looking at the frames: it's a skydiving scene. There's a plane flying above clouds. The text "Skydive Miami" is visible, but according to the rules, I shouldn't include text recognition. So ignore that. The main subject here is the plane. Wait, the initial frames show a plane, then in frame 4, a person jumps out. Wait, the sequence starts with the plane, then maybe the parachute deploying?

Wait, let me check the frames. The first frame has a plane flying above clouds. Then in the next frames, the plane is still there, but in frame 4 or 5, a person is seen with a parachute. Wait, the description says "a person jumps from the plane" but maybe it's the parachute being deployed.

Wait, the user's video description says: "a person jumps from the plane" but in the frames, the video starts with the plane, then the person is seen in the sky with a parachute. Let's see:

Frame 0: Plane in sky, clouds below.

Frame 1-3: Plane continues flying.

Frame 4: Plane is still there, but now a person is visible with a parachute descending.

Frame 5: Person is now lower with parachute fully deployed.

Wait, the video shows a person deploying their parachute. So the sequence is plane flying, then person exits the plane (or maybe the parachute is deployed after jumping).

Wait, the frames mention "a person jumps from the plane" but the actual video description says "Skydive Miami" is visible, but we exclude text. So the main action is the plane moving, then a person jumping out and deploying parachute.

Wait, the problem says the user provided video frames, but the task is to describe the video. Let me parse the input again.

The user provided a video description with 5 frames. The first four frames show the plane, then in frame 4, a person jumps (parachute lines visible), then frame 5 shows the person with parachute descending.

Wait, looking at the frames:

[0.0] Plane in sky above clouds.

[1.4] Plane still there.

[2.5] Plane flying, clouds below.

[3.6] Plane is moving away?

[4.7] Person jumping with parachute lines.

Wait, the frames show the plane moving, then the person starts to descend with parachute.

So the chronological order is: plane flying over clouds, then a person exits the plane (parachute deploying), then the person is seen descending with the parachute.

So the main subjects are the plane and the person. The plane is dark, moving horizontally. The person is smaller, jumps out, parachute opens.

Appearance: Plane is dark, medium size. Person is small, with parachute.

Spatial relationships: Plane is above the clouds, person is below the plane initially, then deploys parachute.

Camera perspective: Maybe the camera is fixed, looking up at the plane, then the person jumps. Wait, but the description says "the person jumps from the plane" and "parachute deployed".

Wait, the user's description says in the video, the plane is moving, then a person is seen with parachute lines, then the parachute is fully deployed.

So the caption should mention the plane flying, then the person jumping with parachute.

But the rules say "focus on motion and behavior of main subjects in chronological order".

So the plane is flying over clouds. Then a person exits the plane (jumps), and the parachute deploys as they descend.

Appearance: Plane is dark, small in frame. Person is smaller, parachute is white or light-colored.

Spatial relationships: Plane is above the clouds, person is below the plane, then descends.

Camera perspective: Maybe the camera is fixed, tracking the plane and the person as they descend.

But the rules say to keep background minimal. So clouds are background, but necessary for understanding motion.

So the caption should be: A dark-colored plane flies above a layer of white clouds. A person exits the plane, deploying a parachute that expands as they descend below the aircraft. The camera remains stationary, capturing the descent against the sky.

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

a) Motion and behavior in chronological order: Plane flying, person jumps, parachute deploys.

b) Appearance and number: Plane (dark, medium), person (small, parachute deploying).

c) Spatial relationships: Plane above clouds, person below plane, descending.

d) Camera perspective: Stationary (since the video shows the plane moving, but the camera might be fixed, but the user says "camera perspective and movement". The frames show the plane moving

A single airplane is moving across the sky from left to right.

The background consists of a clear blue sky and static clouds. The clouds are minimal in motion and not the dominant feature.


RAW CAPTION: Got it, let's tackle this. First, I need to describe the video chronologically. The main subject is a person on a skateboard. Let's check the frames.

In the first frame, the person is near a yellow structure, maybe a bike rack, and there's a car on the left. They're on a skateboard. Then in the next frames, they move forward along the driveway. Let's note their appearance: wearing a blue helmet, dark jacket, gray pants. Number: one person.

Motion: They start standing on the skateboard, then push off and move forward. The background has a black SUV on the left, a yellow and black structure (maybe a bike rack or shed), some tools like a shovel and rake, and orange balls. But according to the rules, keep background minimal unless essential. So maybe mention the SUV and the driveway.

Spatial relationships: The person is on the driveway, with the SUV to their left, and the yellow structure behind them. As they move, they go from near the yellow structure towards the camera.

Camera perspective: The video seems to be shot from a fixed position, maybe a slight angle, but no pan or movement mentioned. The camera is static, probably a medium shot.

Now, structure the caption: Start with the person's action, appearance, movement, background elements as needed, then camera.

Let's draft:

A person wearing a blue helmet, dark jacket, and gray pants rides a skateboard on a concrete driveway, moving forward from near a yellow structure toward the camera. The black SUV is parked to the left, and a shovel, rake, and orange balls are visible nearby. The camera remains stationary, capturing the motion from a consistent angle.

Check rules: a) motion and behavior in chronological order: starts on skateboard, moves forward. b) appearance: blue helmet, dark jacket, gray pants. c) spatial: SUV left, yellow structure behind. d) camera: stationary. e) background minimal: SUV, yellow structure, tools mentioned as essential for context. f) no text or names. g) no reasoning in caption.

Wait, in the frames, the person is pushing off to start moving. So "rides a skateboard" might be accurate. Let's check the frames: frame 0, they're standing on skateboard, then frame 1, they push, frame 2-5 they move forward. So "rides a skateboard, moving forward" or "pushes off from a stationary position and rides forward".

Wait, the first frame: they are on the skateboard, maybe pushing. Then moving. So chronological: starts pushing off from the yellow structure, then rides forward on the driveway.

Adjust: A person wearing a blue helmet, dark jacket, and gray pants pushes off from a stationary position on a concrete driveway, riding a skateboard forward toward the camera. A black SUV is parked to the left, and a yellow structure, shovel, rake, and orange balls are visible in the background. The camera remains fixed, capturing the motion from a stationary angle.

Check minimal background: "yellow structure, shovel, rake, and orange balls" might be too much. Rule e: minimal unless essential. Maybe just SUV and driveway.

Wait, the background elements: the yellow structure is part of the scene, but maybe essential for the setting. But the rules say "minimal unless essential for understanding motion". So maybe the SUV is essential (left side), the driveway is the main area. The person is moving on the driveway.

Let's simplify: A person wearing a blue helmet, dark jacket, and gray pants rides a skateboard forward on a concrete driveway, moving from the right side toward the center of the frame. A black SUV is parked to the left, and a yellow structure is visible in the background. The camera remains stationary throughout.

Check the frames: the person starts near the yellow structure (which is behind them initially), so moving from the right side toward center. The SUV is on the left. So "moving from the right side toward the center" might be right.

Wait, in frame 0, the person is on the right side (of the driveway), then moves forward (leftward? Wait, the driveway is the path. Let's see: the driveway goes from the camera's perspective to the left? No, the video shows the person moving forward along the driveway, which is the path. So the camera is at the end of the driveway, so the person starts at the far end (behind) and moves towards the camera.

Ah, right. The person is initially further back, then moves closer to the camera. So chronological: The person starts standing on a skateboard near a yellow structure and a black SUV on the left, then pushes off and rides the skateboard forward along the driveway toward the camera.

So: A person wearing a blue helmet, dark jacket, and gray pants rides a skateboard forward on a concrete driveway, moving from the

A person is moving: stepping, turning, and shifting posture on the driveway. The car and other background objects are stationary.

No shifting background elements or fluid motion observed. Background (trees, wall, driveway) remains static across frames. No fire, water, smoke, or wind present.


Two individuals, one in a brown hoodie and gray pants, the other in a brown jacket and jeans, stand in front of a large brown box with visible text. The hooded person steps back, the jacketed person bends down near the box, then stands up. The hooded person walks left, while the jacketed person remains positioned near the box. The background features a wooden wall; the camera remains stationary with minimal movement.

Two people interact with a sign: one moves toward the sign, walks around it, and adjusts its position; the other observes and later moves away. Their motion is locomotive (walking, repositioning).

Background elements (curtains, stage floor) remain stationary relative to the frame; no fluid/environmental motion (fire, water, smoke, wind) detected.


A person with a bracelet mixes paint on a white palette using a brush, then shifts to paint on a grid-paper document while seated at a table. The individual, wearing a blue shirt and having blonde hair, works near a paper plate with paint, a bottle of Windex, and additional documents. The camera moves from a top-down view of the hands to a wider shot showing the person at the table with windows displaying greenery in the background.

Discrete solid objects include hands (human) moving a brush across a palette, and a person seated at a table with a cup and papers. Motion is deliberate and driven by human action.

The background includes a window with static outdoor greenery and table items; no fluid or wind-driven motion observed. Background elements do not shift uniformly, indicating no ambient environmental motion.


tags. </think>  <caption_output>A woman with long brown hair, wearing a red top and black cardigan, stands centered against a bright yellow background. She initially smiles at the camera, then raises her right hand to give a thumbs-up gesture, and subsequently lowers her hand. The camera remains static, maintaining a medium shot perspective throughout.

A woman (discrete solid object) is making hand gestures and facial expressions (e.g., thumbs-up, pointing), indicating intentional locomotion of limbs due to her own physical actions.

Static yellow wall with no environmental motion (no fire, water, smoke, or wind). Overlaid text 'tudo bem?' is static and does not contribute to motion.


RAW CAPTION: Got it, let's break this down. First, the video starts with a person wearing a hairnet, holding a tray of small, rectangular pastries. They're near a microwave. Then, the person moves the tray, and the camera shows them carrying it to another area, maybe a kitchen counter. Next, there's a close-up of the pastries on the tray, then they're placed in an oven. Finally, the video shows the baked pastries on a plate. Need to keep it chronological, focus on motion and behavior.

First frame: person with hairnet, holding tray with pastries, near microwave. Then they move the tray (probably to the oven). Then the camera shows the tray being placed into an oven. Then the baked pastries on a plate. Wait, the second frame shows the person opening the microwave? Wait no, the first frame is person holding tray, then next frame they're moving the tray towards the oven. Then the third frame is the tray being carried, then the fourth frame is a close-up of the tray (maybe before baking), then the fifth frame is the baked pastries on a plate.

Wait, the video sequence:

0.0: person with hairnet, holding tray of small pastries, standing next to microwave. Person is on the right, tray in hand.

1.1: person moves tray towards the oven (which is next to the microwave? Or maybe the oven is on the counter).

2.2: person is carrying the tray to another location (maybe an oven or counter), and there are other trays with pastries.

3.3: close-up of the tray with pastries being placed into an oven (but the oven door is open?).

4.4: close-up of the baked pastries on a plate, showing the texture.

So the main subject is the person moving the tray of pastries to the oven, then the baked pastries on a plate.

Now, description:

Person wearing hairnet, holds tray with multiple small, rectangular, light-colored pastries. Moves tray from microwave area toward oven, then places tray into oven. After baking, close-up shows pastries on a decorative plate. Camera starts with a medium shot, follows tray movement, then shifts to close-up of baked pastries.

Wait, need to be precise. Let's check each frame:

Frame 0: Person (hairnet, light top) holds a black tray with many small rectangular pastries (light beige, arranged in rows) near a black microwave. Person is on right side of frame.

Frame 1: Person moves tray (holding with both hands, tray visible) towards a different area, background shows a room with chairs and tables.

Frame 2: Tray is being carried, now in front of a counter with other trays (similar pastries) and a black oven.

Frame 3: Close-up of tray with pastries, then the tray is placed into an oven (oven door open, person's hand guiding tray).

Frame 4: Close-up of the baked pastries (now golden-brown, crispy texture) on a white plate with fruit patterns.

So chronological:

A person wearing a hairnet holds a tray of small rectangular pastries and moves it from near a microwave to a counter. The person then places the tray into an oven. After baking, the pastries are shown on a plate. Camera starts with a medium shot, follows the person's movement, then shifts to a close-up of the baked pastries.

Now, check rules:

a) Motion: person holds tray, moves it, places in oven, then baked pastries on plate.

b) Appearance: pastries are small, rectangular, light-colored (before baking), golden-brown (after). Person's hairnet and top.

c) Spatial: person near microwave, moves to counter, oven.

d) Camera: starts medium shot, follows movement, then close-up.

e) Background minimal: only mention essential (microwave, oven, plate).

f) Exclude text, named characters.

So write in chronological paragraph.

"Person wearing a hairnet holds a black tray with multiple small, light-colored rectangular pastries near a microwave, then moves the tray to a counter and places it into an oven. After baking, the golden-brown pastries are displayed on a decorative plate. Camera transitions from medium shot of the person's movement to close-up of the baked pastries."

Wait, need to check number of pastries. In frame 0, tray has many (maybe 24? 6x4), but "multiple" is fine. Before baking, pastries are light, after baked they're golden.

Also, frame 0 shows person's arm and hairnet, then moving tray. So "person wearing a hairnet holds a tray with numerous small rectangular pastries, then transports the tray toward an oven and inserts it. The camera then

A person (discrete object) moves a baking tray containing baked goods (discrete objects), interacting with the oven and countertop. Motion is driven by human locomotion and object handling.

Background elements (walls, floor, oven) show no uniform shifting or fluid motion; no fire, water, smoke, or wind present.


A hand holding a white cloth approaches a wooden board with a brown bottle positioned to its right. The hand places the cloth on the board, then positions a red ink pad and presses it onto the board, spreading the red ink across the surface. The glass of water remains above the board. The camera maintains a top-down perspective throughout.

A human hand is moving, interacting with a glass (holding it) and a wooden board (spreading a red substance across the board surface).

No shifting backgrounds or fluid/environmental motion observed. Table surface, bottle, and glass maintain fixed positions relative to the frame throughout the sequence.


A man wearing a blue and green striped shirt and dark pants sits on the floor with his hand on his head. A young girl in a striped top and pink skirt stands to his right, then bends down to pick up shoes from the floral-patterned bed, rises, and holds the shoes up toward the man. The camera remains stationary throughout the scene.

A child in a pink skirt moves toward a seated adult, bends down to interact with an object on the floor, and gestures toward the adult. The adult makes hand movements, indicating physical interaction.

The background elements (bed, furniture, walls) show no shifting or uniform motion. No fluid/environmental elements (fire, water, smoke) are present.


A person in a blue shirt with yellow graphics enters the frame from the right, moving left across the storage room with blue and yellow life jackets on the wall and a white door in the background; they raise their right arm while walking, then continue moving left before exiting the frame. The camera remains stationary.

A person in a blue shirt moves across the frame, exhibiting locomotion (walking, turning, gesturing), with clear bounding box tracking.

The static background elements (walls, door, hanging blue/yellow items) show no uniform shifting or fluid motion; no fire, water, smoke, or wind observed.


A person holds a dark black hair bundle with their left hand (light-colored sleeve visible), while their right hand (green nail polish) maneuvers a blue electric hair clipper to trim the hair. The clipper moves along the hair’s length, cutting it. The camera maintains a close-up, slightly shaky perspective focused on the clippers and hair, with minimal background details.

A hand holding a small black animal (likely a cat) with a blue electric clipper; the clipper is moved across the animal's paw for trimming, indicating intentional physical interaction.

Background elements (computer monitor, papers, office items) show minimal uniform shifting; no fire, water, or smoke present.


A person in a white karate uniform with a black belt holds a light wooden board, first placing hands on its surface before flipping it and moving it through the air, then standing upright while holding the board; the camera follows the motion with a slight shake, focusing on the subject against a wooden floor background.

A person in a karate uniform (wearing a black belt) manipulates a wooden board through lifting, positioning, and preparatory movements. The board is a solid, distinct object undergoing motion due to the person's physical actions.

The wooden floor and walls show no uniform shifting or fluid/environmental motion (fire, water, wind). Static background elements remain stable across frames.


A shirtless young boy sits surrounded by purple balloons, holding a pink object. He brings the object to his mouth, then shifts it near his face with both hands. The camera maintains a close-up perspective with slight movement, focusing on the boy’s actions as he interacts with the object while seated among the balloons.

Boy inflates a balloon via breath; balloon expands visibly due to air pressure. Boy's hands/mouth move to blow air, but the dominant discrete motion is the balloon's inflation caused by explicit physical force (breath).

Background consists of static purple balloons and a person in a green shirt. No shifting background elements (walls/ground do not move uniformly), and no fluid/environmental motion (fire, water, wind). Scene is stable with no ambient effects.
