RAW CAPTION: Got it, let's break this down. The video shows a person adjusting a microscope. First, there's a close-up of hands in blue gloves opening the field diaphragm. Then, the next part shows adjusting the condenser diaphragm with a lever. The main subject is the hands and the microscope parts. Need to describe chronologically: first opening the diaphragm, then adjusting the condenser. Mention the blue gloves, the microscope components like the diaphragm and lever. Check the rules: no text recognition, so ignore the subtitles. Focus on motion: hands moving the knobs, the diaphragm opening, then adjusting the condenser. Spatial relationships: hands are on the microscope, maybe the lever is part of the condenser. Camera perspective: close-up shots, probably static except for the movement of hands. Keep it concise.

First part: hands in blue gloves turn the field diaphragm knob, causing the microscope's view to show the edges being out of view. Then, hands adjust the condenser diaphragm lever, changing the contrast. The objects: microscope parts (field diaphragm, condenser diaphragm), blue gloves. Motion: rotating the knob, moving the lever. Background: not essential. Conclude with camera perspective as close-up, static.

So the caption should start with the hands opening the field diaphragm, then adjusting the condenser. Check the order: frame 0-1 is opening field diaphragm, frame 2-4 is adjusting condenser. So chronologically: first, hands adjust the field diaphragm until edges are out of view, then adjust the condenser diaphragm with a lever.

Now, structure: "Hands in blue gloves rotate the field diaphragm knob of a microscope, opening it until the edges of the observed specimen are no longer visible; subsequently, the hands adjust the condenser diaphragm lever, modifying the light intensity and contrast of the image. The camera maintains a close-up perspective, focusing on the microscope components and the gloved hands during adjustment."

Wait, but need to check if "specimen" is okay—wait, the right side shows a pinkish field with dots, which is the specimen. But rule f says exclude text recognition, but the specimen is part of the object. However, the rules say "briefly describe appearance"—the specimen has dots, but maybe better to say "observed field" since it's a microscope image.

Also, the blue gloves: color, so mention blue. Number: one pair of hands (two gloved hands).

Let me check the steps:

1. Start: Hands in blue gloves adjust the field diaphragm—rotating the knob. The field diaphragm is part of the microscope, so describe the action. The view on the right shows the specimen (dots and a line), but the action is the adjustment.

2. Then, adjust the condenser diaphragm with the lever. The lever is adjusted, changing the contrast.

So the caption: A pair of hands in blue gloves first rotates the field diaphragm knob of a microscope, gradually opening it to exclude the edges of the observed field; then, the hands move the condenser diaphragm lever to adjust the light intensity and contrast. The camera remains focused on the microscope's components and the gloved hands throughout, capturing close-up views of the adjustment process.

Check for chronological order, motion, appearance (blue gloves, microscope parts), spatial (hands on microscope), camera perspective (close-up, static).

Yes. Now make it concise. Remove extra words. Maybe "A pair of blue-gloved hands first turns the microscope’s field diaphragm knob to open it until specimen edges are out of view, then adjusts the condenser diaphragm lever to modify contrast. The camera maintains close-up shots of the adjustments."

Wait, but the rule says "concise, chronological paragraph". Let's see the example.

Wait, the video has two main actions: open field diaphragm, then adjust condenser. So first action: hands opening field diaphragm (knob rotation), second: hands adjusting condenser lever.

Appearance: blue gloves, microscope parts (field diaphragm, condenser lever).

Motion: turning knob, moving lever.

So:

A pair of blue-gloved hands adjusts the microscope’s field diaphragm knob to open it, removing the specimen edges from view, then manipulates the condenser diaphragm lever to fine-tune the contrast. The camera stays in close proximity to the microscope components and gloved hands during both adjustments.

Check if "specimen edges" is necessary. The text says "edges are out of view", so the field diaphragm is opened until edges are out. So maybe "opens the field diaphragm until the edges of the observed area are no longer visible".

But the rule says "brief

Hands with blue gloves are moving toward and interacting with a pink surface (likely skin), indicating deliberate physical motion due to human interaction.

No shifting background elements observed; left side static equipment remains consistent, right side shows a pink surface (likely skin) with subtle changes but no fluid/environmental motion (fire, water, wind) dominating.


A baby wearing a white knitted hat with colorful patterns and a bib sits in a blue high chair. A hand enters the frame and touches the bib, then withdraws; the baby shifts their head slightly. The scene is filmed with a static camera.

The baby is moving: turning head, mouth movements, hand movements. An adult hand briefly appears to feed the baby.

Background is static with no shifting (walls, window, door remain stationary). No ambient environmental elements (fire, water, smoke, wind) are present.


A person in a white lab coat adjusts the microscope's 40x objective lens to the working position, then rotates the focus knob to sharpen the sample view, with the camera focusing closely on the lens mechanism and the hand's motion. The background remains a tiled lab surface, and the camera shifts from a medium shot of the microscope to close-ups of the objective lens and focus adjustment.

A person's hands move the microscope's focus knob and stage controls; hands interact with the microscope's physical components.

White tiled walls and countertop remain static throughout; no fluid/environmental motion (fire, water, smoke, wind) observed. Background elements do not shift uniformly.


Six individuals in blue and white robes stand in a line, singing with open mouths and occasional hand gestures; the camera pans right, revealing more members of the group from left to right.

Multiple choir members in blue-and-white robes are visible, exhibiting coordinated hand gestures and subtle body movements consistent with singing or performing.

The background features a static blue-lit stage with a microphone stand and uniform lighting. No fluid motion (fire, water, smoke) or significant ambient environmental movement is observed.


A person in a pink shirt uses chopsticks to adjust two tilted soda cans (one green, one red) on a wooden table, then steps back, causing the cans to fall. The camera remains stationary at a low angle against a tiled background.

A person in a pink shirt manipulates two soda cans (green and red) on a table using a straw. The person's hands and the cans exhibit deliberate motion due to direct physical interaction (e.g., positioning cans, using the straw).

The background consists of a static tiled wall and wooden table with no shifting or fluid motion. No environmental elements like wind, water, or smoke are present.


A child in a pink shirt stands to the left of an adult in a dark shirt and light shorts seated on a bed, holding a baby. The child holds a green object and moves it toward the adult, then raises it upward. The adult leans forward slightly, interacting with the child while keeping the baby secured. The camera remains static, capturing the scene from a fixed angle.

Young girl moves her arms (giving an object and withdrawing). Man moves arms to interact with girl and hold baby. Baby is held with minimal movement.

Background (bed, crib, walls) is static. No fire, water, or wind motion present.


A person with dark braided hair and a dark floral-patterned top begins by looking downward, then lifts their head slightly, and subsequently raises their right hand toward their face. The solid light purple background remains consistent throughout. The camera maintains a close-up perspective with no noticeable movement.

The person's head and hand are moving; specifically, the person is adjusting something near their face (e.g., hair or an object).

The background is a static, uniform pink color with no fluid or environmental motions (fire, water, wind). Background elements are not shifting uniformly.


A person in a dark jacket, light gray pants, and cap swings a bat, then turns toward a green bucket with a yellow band, bends down to adjust the bucket's apparatus, stands upright, and prepares to swing again. The camera remains stationary, capturing the actions from a fixed perspective in the batting cage.

A person swings a bat, hits a ball (causing motion), then bends to retrieve the ball from a bucket. The bat, ball, and person exhibit discrete solid object motion due to physical forces (swinging, collision, locomotion).

The background elements (walls, green floor, red/green buckets) show no uniform shifting or fluid motion. No fire, water, smoke, or wind is present.


RAW CAPTION: Got it, let's break this down. First, the video shows kids playing hopscotch. There are two main kids in the foreground. Let's check the sequence.

At [0.0], two children are on the hopscotch grid. The first kid (left) is stepping on 4, the second (right) on 5. Then in [1.0], the left kid moves to 3, right kid to 4. Then [2.0] the right kid jumps to 3, left kid moves back. Wait, the next frames: [2.5] the kid who was on 5 (right) is moving forward, then [3.5] they jump to a square, then [4.5] the kid moves left, and [5.0] the other kid is moving away.

Wait, let's track the main subjects. There are two boys in school uniforms (blue shirts, dark shorts, backpacks). They're playing hopscotch on a yellow grid with numbers. The motion is them hopping on the squares.

Chronological order: First, two boys stand on the hopscotch grid. The boy on the left (with backpack) hops from square 4 to 3. The boy on the right (also with backpack) hops from square 5 to 4. Then the boy on the right continues hopping forward, moving to square 3, while the boy on the left moves backward. Then the boy on the left jumps to square 12, and the boy on the right moves away. Wait, need to check the frames.

Looking at the video:

[0.0] - two boys, left one on 4, right on 5.

[1.0] - left boy moves to 3 (hopping), right boy moves to 4.

[2.0] - right boy is hopping to 3, left boy is moving left.

[3.0] - right boy jumps to a square (maybe 2?), left boy is walking away.

Wait, the description says "two children standing on the hopscotch grid". Let's focus on their actions.

First, they start on the grid. Then they hop over the squares. The camera is static? Wait, the video might have some camera movement, but the rules say mention camera perspective.

The background: schoolyard with yellow railings, building. But background is minimal.

Appearance: two boys, same school uniforms (blue shirts, dark shorts, backpacks). Number: two.

Motion: they take turns hopping on the hopscotch squares. First, the left boy hops from square 4 to 3. Then the right boy hops from square 5 to 4. Then the right boy continues hopping forward, moving to square 3, while the left boy moves backward. Then the left boy hops to square 12, and the right boy moves away.

Wait, the exact frames:

Frame 0: both on grid, left on 4, right on 5.

Frame 1: left moves to 3, right moves to 4.

Frame 2: right hops to 3, left moves left.

Frame 3: right is jumping to a square, left is walking.

Frame 4: right is on 3, left moves left.

Frame 5: right moves to a new spot, left moves left.

Wait, maybe the main actions are two boys hopping on the hopscotch grid. They take turns. The camera is mostly static, maybe slightly following their movement.

Need to describe chronologically: the two boys start on the grid, then one hops over squares, then the other, then one moves back.

Also, mention spatial: the boys are on the grid, with the building and railings in the background.

Camera: the camera is stationary, capturing the scene from a medium distance.

Let's structure the caption:

Two boys in school uniforms (blue shirts, dark shorts, backpacks) stand on a yellow hopscotch grid marked with numbers. The boy on the left hops from square 4 to 3, while the boy on the right hops from square 5 to 4. The right boy continues hopping forward to square 3, then moves left, and the left boy hops to square 12 and walks away. The camera remains stationary, capturing their movement on the grid with a school building and yellow railings in the background.

Check rules: focus on motion in chronological order, appearance (color, size, orientation), spatial (in front of, left), conclude with camera.

Wait, the first frame: "two children standing on the hopscotch grid" – their appearance is school uniforms. Number is two.

Motion: they hop on the squares. First, left hops to 3, right hops to 4. Then right continues to hop forward

Two children in school uniforms are moving via hopscotch locomotion (hopping, stepping). Additional children and an adult in the background exhibit minor movement but are not the primary focus.

Static background elements (railing, building, greenery) show no uniform shifting. No fire, water, smoke, or wind present; ambient environmental motion is absent.


A hand stirs a vibrant mixture of vegetables and meat in a black wok over a gas stove burner using a metal spoon. The wok is then lifted and removed from the burner, revealing the empty cooking surface. The scene concludes with a top-down view of the finished dish plated on a white dish beside a red tablecloth.

A person uses tongs to stir and transfer cooked food (with vegetables and meat) in a wok, with discrete motion of the wok, tongs, and food pieces.

The background (stove, countertop, surrounding kitchen elements) shows no uniform shifting; there is no fire, water, smoke, or wind dominating the scene.


A black frying pan on a stove holds seasoned, golden-brown chicken pieces, with a wooden spatula having a red handle resting on the pan. The spatula is used to flip and reposition the chicken pieces within the pan, causing them to shift and change orientation. The camera maintains a close-up perspective, slightly shifting to follow the spatula’s movements.

A wooden spatula and cooked eggs in a frying pan exhibit motion: the spatula moves to stir and mix the eggs, with the eggs themselves shifting as they are manipulated.

No shifting background elements observed; stove and kitchen environment remain static throughout. No fire, water, smoke, or wind-driven motion detected.


RAW CAPTION: Got it, let's break this down. First, the video starts with a person wearing a beanie and a dark jacket standing near gray lockers. Then another person, wearing a hat and a dark coat, approaches. The second person takes a yellow envelope from the first person's hand and gives it back? Wait, no, the first person is holding a yellow envelope. Wait, the second person comes in, takes the envelope from the first person. Let's check the frames.

Frame 0: Person 1 (beanie, dark jacket) is there. Person 2 (hat, dark coat) enters from left. Frame 1: Person 2 approaches. Frame 2: Person 2 takes an envelope from Person 1's hand. Frame 3: Person 2 holds the envelope, Person 1 is looking up. Frame 4: Person 2 walks away, Person 1 is still there holding something. Frame 5: Person 2 exits, Person 1 is holding the envelope?

Wait, the actions: Person 2 enters, interacts with Person 1, takes an envelope (yellow, maybe), then leaves. So chronological order: First, Person 1 is near lockers. Person 2 enters from left, approaches Person 1. Person 2 reaches out, takes an envelope from Person 1's hand. Person 1 holds up their hand, maybe in surprise or letting go. Person 2 walks away. Person 1 is left holding something.

Now, appearance: Person 1 has a beanie, dark jacket. Person 2 has a straw hat, dark coat. Lockers are gray, multiple small compartments.

Spatial: Person 1 is right of the lockers? Wait, in the video, the lockers are in the background. Person 1 is standing near the lockers, to the right. Person 2 comes from the left, approaches.

Mentions of motion: Person 2 enters, moves towards Person 1, takes envelope, exits. Person 1 remains in place, then maybe holds up their hand.

Camera perspective: It's a static shot, maybe slight angle, but no camera movement. The video is a fixed camera capturing the scene.

Now, following the rules:

a) Motion chronology: Person 2 approaches Person 1, takes an envelope, then walks away. Person 1 is initially present, then interacts, then after Person 2 leaves, Person 1 remains.

b) Appearance: Two people. Person 1: beanie, dark jacket. Person 2: straw hat, dark coat.

c) Spatial: Person 2 enters from left, approaches Person 1 (who is near lockers).

d) Camera: Fixed, no movement.

e) Background: gray lockers, but minimal description.

f) Exclude text, names.

So putting it together:

A person wearing a dark jacket and beanie stands near gray lockers, holding a yellow envelope. Another person, dressed in a dark coat and straw hat, enters from the left, approaches the first person, takes the yellow envelope, and walks away. The first person remains holding their hand upward. The camera maintains a fixed position throughout the sequence.

Wait, check the video: Frame 0: Person 1 (beanie, dark jacket) is there. Frame 1: Person 2 (hat, coat) enters from left. Frame 2: Person 2 moves to Person 1, takes an envelope (which Person 1 is holding). Frame 3: Person 2 is holding the envelope, Person 1's hand is up. Frame 4: Person 2 walks left, exits. Frame 5: Person 1 is alone, holding something.

Wait, in frame 2, Person 2 takes the envelope from Person 1's hand. Then Person 1's hand is up, maybe letting go. Then Person 2 walks away. So the action is: Person 2 approaches, takes the envelope, leaves. Person 1 is there initially, then after the handover, maybe holds up their hand.

So the caption should be chronological: Initially, a person in a beanie and dark jacket stands near gray lockers holding a yellow envelope. Another person in a dark coat and straw hat enters from the left, moves toward the first person, takes the yellow envelope, and walks away. The first person then raises their hand while remaining near the lockers. The camera remains stationary throughout the interaction.

Wait, but need to check if "raises their hand" is accurate. In frame 3, Person 1's hand is up. So yes.

Now, check rules:

a) Motion: Person 2 enters, takes envelope, leaves. Person 1 is there, then raises hand.

b) Appearance: Two people. Person 1: beanie, dark jacket; Person 2: straw

Two individuals are interacting: one person adjusts the other's clothing and handles a small object (e.g., a package), resulting in discrete, solid-object motion.

The background elements (mailboxes, wall) are stationary with no shifting or fluid motion; no fire, water, or wind effects observed.


A person reclines on a treatment table, wearing a yellow sweater and a green head covering, with a white facial mask applied. Another individual stands beside the table, their hands moving across the reclined person’s face, massaging the cheeks and forehead in gentle motions. The camera remains stationary, capturing the interaction from a frontal perspective.

The therapist's hands are moving in a controlled manner to apply massage pressure on the patient's head and neck; the patient remains largely stationary.

The background consists of stationary elements (wall, furniture, shelf) with no shifting or environmental motion (no fire, water, smoke, or wind).


text

A person in a red shirt and jeans is moving: extending arms, bending, falling, recovering, and walking across the scene.

Background elements (door, walls) are static with no uniform shifting or fluid motion (fire, water, smoke, wind).


A person wearing a white t-shirt plays a brown ukulele; the left hand frets the strings while the right hand strums rhythmically. The ukulele is held horizontally, positioned in front of the person. The camera maintains a close-up view centered on the hands and instrument, with slight movement tracking the strumming motion.

Person's hands moving to play ukulele: left hand fingering frets, right hand strumming/plucking strings.

Background is static indoor setting with no shifting elements or environmental phenomena (no fire, water, wind).


RAW CAPTION: Got it, let's break this down. The task is to create a concise caption following the rules. First, identify the main subject: a person in an orange shirt. They're interacting with objects on a desk. The video starts with the person reaching towards a container (maybe with snacks), then moving their hand to the computer monitor. Let's check the chronological order.

Frame 0: Person in orange shirt is reaching towards a container on the desk. The desk has a computer, monitor showing a red character (but we can't mention named characters), some items. The person's arm is extended.

Frame 1: Still reaching, maybe adjusting.

Frame 2: Closer view of the monitor, person's hand near the monitor. The container is still there.

Frame 3: Person moves their hand towards the container again? Wait, no, the sequence: the person is manipulating items. Let's see: in the first few frames, the person is holding something (maybe a snack bag) and moving it. Then, in frame 2, they reach towards the container, then in frame 3, they're moving their hand over the container. Wait, no, the description says: "a person in an orange shirt is reaching towards a container on the desk" and then "moves their hand to the computer monitor" but actually, the frames show the person's hand moving towards the container, then possibly picking up or placing something.

Wait, the video shows the person (orange shirt) reaching for the container, then moving their hand to the monitor. Let's check the frames:

- Start: Person in orange shirt, arm extended towards container on desk. Desk has computer, monitor with red character, other items (pink folder, etc.)

- Frame 2: Closer view, hand reaching towards container.

- Frame 3: Hand is on container, maybe taking something.

- Frame 4: Hand moves towards monitor, pressing or pointing.

- Then back to container.

Wait, the sequence is: person reaches for container (grabbing/scooping?), then moves hand to monitor, perhaps interacting with it.

Now, following the rules: focus on motion. Main subject is the person (orange shirt, short hair). Actions: reaches towards container on desk, then moves hand to computer monitor (interacting with screen). Spatial: container is on desk, monitor is behind it (so desk has computer, monitor in front of container? Wait, the desk has the monitor, and the container is to the right of the monitor? Maybe.

Appearance: person in orange shirt, arm visible, moving. Container is small, maybe with snacks. Monitor shows a red character, but we can't mention that (rule g: exclude text recognition, named characters).

Chronological order: person reaches for container (action 1), then moves hand to monitor (action 2).

Background: minimal, desk with computer, monitor, container, other items (pink folder, but maybe not essential).

Camera: starts with a shot, then slightly shifts to show more of the monitor (pan left?).

Rule d: camera perspective and movement. The video starts with a medium shot, then the camera moves slightly to the left (pan left) to focus on the monitor area, then back.

Now, structuring the caption:

- Person in orange shirt reaches toward a container on the desk, then moves their hand toward the computer monitor.

- Spatial: container is on the desk, monitor is on the desk behind it? Or monitor is central, container to the right.

Wait, in frame 0: monitor is left of container, person is reaching to the right (container). Frame 2: closer, container is in front of the monitor. So container is to the right of the monitor.

So person is reaching toward container (on the right side of the desk), then moves hand toward monitor (left side of desk).

Appearance: person in orange shirt, short hair. Container is small, holds snacks (but can't mention "snacks", maybe "container with items").

But rule b: briefly describe appearance and number (color, size, orientation). So person is in orange shirt, size is medium (assuming), orientation is standing at desk.

Chronological order: person reaches toward container on desk (action 1), then moves hand toward computer monitor (action 2).

Background: minimal, desk with computer, monitor, container, other desk items (but not detailed).

Camera: starts with medium shot, then camera shifts left (pan left) to focus on the monitor and person's hand moving.

Now, let's draft:

A person in an orange shirt stands at a desk, reaching toward a container on the right side, then moving their hand toward the computer monitor. The desk holds a monitor displaying an animated character, a keyboard, and various items. The camera pans left slightly to show the monitor as the person interacts with it, maintaining

A person wearing an orange shirt and white gloves moves their arm and hand to paint on a surface using a brush.

The background (walls, computer monitor, desk items) is static and does not shift uniformly. There is no environmental motion (e.g., fire, water, smoke, wind) present.


Three individuals stand on a sandy beach with the sea in the background. The person on the left wears black, the middle individual wears a yellow top and black pants, and the person on the right wears black. Initially, all extend their arms outward. Then the person on the left raises their arms, the middle individual shifts arms and lifts their right leg, while the right person mirrors movements. The camera remains static, capturing the group from a frontal perspective.

Three discrete solid objects (people) are moving through coordinated locomotion and arm gestures, indicative of dance or exercise. Their motion is tracked with consistent bounding boxes and is physically driven by their own movements.

The background consists of a static beach and ocean; subtle wave motion is present but not dominant. No significant environmental fluid dynamics (e.g., fire, smoke, turbulent water) are the primary motion.


RAW CAPTION: Got it, let's see. The video shows people unloading white barrels from a truck. First, there's a blue ramp connecting the truck to a building. A person in dark clothes and jeans is on the truck, moving barrels down the ramp. Another person in a gray shirt and blue cap is pushing a red cart or something? Wait, no, in the first frame, two people are at the bottom of the ramp. Wait, let's check the frames.

Frame 0: Three people near the ramp. One on the truck, two at the bottom. The truck has white barrels. The person on the truck is handling barrels. Then in frame 1, the person on the truck is moving a barrel down the ramp. Frame 2: the person on the truck is still there, and the others are moving. Frame 3: same. Frame 4: the person on the truck is pushing a barrel down the ramp. Frame 5: the person is descending the ramp.

Wait, main subjects: multiple people, white barrels, blue ramp, truck. Chronological order: people are moving barrels from the truck to the building. The person on the truck (dark shirt, jeans) is pulling barrels down the ramp. Others are at the bottom, maybe receiving or moving them. Let's check the video.

First, in frame 0, two people at the bottom of the ramp (one in gray shirt, blue cap, holding red hose? Wait, no, maybe a tool), and a person on the truck. Then in frame 1, the person on the truck is moving a barrel. Frame 2: they continue. Frame 3: the person is now on the ramp, moving a barrel. Frame 4: still moving. Frame 5: the person is halfway down the ramp.

So the main motion: A man in dark shirt and jeans stands on a truck loaded with white barrels, guiding a barrel down a blue loading ramp toward a building. Other individuals near the ramp assist. The camera pans left, following the action. Background: industrial building, some vehicles.

Need to mention appearance: dark shirt, jeans; white barrels. Spatial: on truck (ramp), building entrance. Camera movement: pans left.

Wait, the caption should be concise. Let's structure it.

Start with the main action: Men unload white barrels from a truck via a blue ramp. One man in dark shirt and jeans on the truck guides a barrel down the ramp. Others near the building entrance assist. Camera pans left, following the movement.

Wait, the first frame shows two people at the bottom, one in gray shirt and blue cap (maybe pushing something), another in gray shirt. Then the truck person is on the ramp. So in chronological order: The man on the truck (dark shirt, jeans) is handling white barrels, pulling them down the blue ramp. The other individuals are at the base of the ramp, moving toward the building. The camera slowly pans left, capturing the unloading process.

Let me check the rules. Focus on motion and behavior, chronological. Main subjects: people (men), barrels. Appearance: white barrels, man in dark shirt/jeans, others. Spatial: ramp connects truck to building. Background minimal.

So the caption should be:

Three men unload white barrels from a truck via a blue ramp; one man in dark shirt and jeans on the truck guides a barrel down the ramp while two others near the building entrance assist. The camera pans left, following the movement.

Wait, but how many people? Frame 0: three people. One on truck, two at bottom. Frame 1: same. So three men total.

But need to be concise. Let's see:

A man in a dark shirt and jeans on a red-trailer truck loads white barrels onto a blue ramp, descending toward a building. Two other men near the building entrance assist. The camera pans left, tracking the unloading process.

Wait, no, the video is unloading, not loading. The barrels are being moved from truck to building. So "unloading".

So: A man in dark shirt and jeans on a red-trailer truck unloads white barrels via a blue ramp, moving a barrel down the slope toward a building. Two other men near the entrance assist. The camera pans left, following the action.

Wait, the first frame shows the man on the truck, and then he moves a barrel down. So chronological: The man on the truck guides a white barrel down a blue ramp to a building, with two other men assisting at the base. The camera pans left, capturing the unloading sequence.

Yes. Let's make it concise.

"Three men unload white barrels from a red-trailer truck via a blue ramp; one man in a dark shirt and jeans on the truck guides a barrel down the ramp while two others near the building entrance assist. The camera pans left

Two people: one moving down the ramp (from truck to building) and one moving up the ramp (from building to truck).

The background (building, ground) is static with no fluid or wind motion.


A group of dancers in green uniforms with yellow trim performs a synchronized routine, advancing in unison across a paved area. Initially forming a line, they transition to a scattered arrangement while stepping forward, maintaining coordinated arm and leg movements. The crowd stands in the background, observing. The camera pans left to follow their progression.

Discrete solid objects (people in uniform) are moving in coordinated locomotion (dancing), with visible bounding box tracking across frames.

Static background elements (trees, spectators) show no uniform shifting; no fire, water, smoke, or wind-driven motion observed.


Two small puppies, one with brown and white fur and the other with darker coloring, move together on a dark conveyor belt, with the brown and white puppy leading while the darker puppy follows and nudges it; a person's leg in light-colored pants is visible above them, partially obscuring the view. The camera maintains a close, slightly shaky perspective, tracking their movement from above.

A small dog (with brown, black, and white fur) is running on the treadmill belt. The person's legs (in khaki pants and brown shoes) are moving as they walk the dog.

The background (treadmill frame and floor) is stationary; no shifting of static elements or fluid/environmental motion (fire, water, smoke, wind) is present.


A blonde woman in a floral-patterned top and sunglasses holds a cigarette-like object, bringing it to her mouth while seated closely beside a man in a dark shirt and sunglasses who points toward her; they remain against a red wall, with the camera maintaining a static close-up perspective.

Two distinct solid objects (a woman and a man) exhibit intentional motion: the man gestures with a small object (likely a cigarette), points toward the woman, and shifts position; the woman turns her head, takes the object, and brings it to her mouth. All movements are voluntary locomotion/locomotion-based actions.

The solid orange background wall remains completely static throughout the video. No ambient environmental motion (fire, water, smoke, wind) is present; the scene lacks fluid or gaseous elements.


A shirtless person washes dishes at a kitchen sink, moving their hands over a plate and shifting position while handling the dish. They turn slightly to the side, continuing the washing motion with kitchen items visible on the counter behind them. The camera remains fixed with a slight shake, capturing the person’s actions from a frontal perspective.

A shirtless person moves their hands and body to wash dishes (scrubbing, lifting, placing), with dishes being manipulated as discrete solid objects. Motion involves clear physical interactions (hand-dish contact, water splashing from controlled actions).

Kitchen background (sink, counter, walls) is static; no uniform background shift detected. Water in sink is controlled by the person's actions, not dominant ambient motion (fire, water flow, smoke, or wind).


A person manipulates a cloth (folding, unfolding, shaking) using hand movements; cloth and person are discrete solid objects.

Background shelves and poster remain static with no uniform shifting; no fire, water, or smoke present.


A person wearing a black and white hoodie and blue jeans holds a pressure washer nozzle, spraying water onto a concrete surface near a wall with attached items. They lower the nozzle, step back, and turn to face the camera while continuing to hold the nozzle. The camera follows their motion with a slight shake, capturing their actions in a dimly lit indoor space.

A person actively moves a leaf blower (discrete solid object) across the ground, causing displacement of debris. The blower's motion is directly controlled by the person's locomotion and physical force.

The background (wall with graffiti and ground with debris) remains static with no significant fluid motion (fire, water, smoke, or wind) dominating the scene. Ambient elements like falling leaves are secondary to the subject's actions.


A baseball player in a red helmet, white uniform, and number 1 stands at home plate, swings a bat, and hits the ball. The catcher in dark gear crouches behind the batter, while an umpire stands behind the catcher. A fielder in a red uniform runs toward the ball in the background. The camera starts close to the batter, then pulls back to show the batter’s motion toward first base and the fielder’s reaction, maintaining a steady perspective.

Batter swinging the bat, baseball in motion after being hit, runner moving toward first base, and catcher/umpire maintaining positions.

No fire, water, smoke, or significant wind. The background elements (fence, houses, grass) are static but show minor shifts due to camera movement, which does not dominate the scene.


A person in a blue shirt and cap plays an electric guitar while seated at a desk, strumming and adjusting the instrument. The desk holds a keyboard and mouse, with a bright window behind them. The camera remains static throughout.

Briefly describe what discrete, solid objects are moving.

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


A person in black pants and green-and-white sneakers rides a skateboard with green wheels on a light-colored concrete surface, lifting their feet to flip the board upward. They then approach concrete steps, jump over them, and the skateboard’s colorful underside becomes visible. The camera follows the motion with a low-angle perspective, keeping background elements minimal.

The skateboarder (legs, feet, and skateboard) is the discrete object moving due to physical locomotion and trick execution (e.g., ollie, kickflip), with clear bounding box tracking of the skateboard's motion.

The concrete steps and ground in the background show no uniform shifting or fluid/environmental motion (e.g., wind, water, smoke). Trees and sky are static, indicating no dominant ambient phenomena.


A boy in a light blue shirt and glasses sits across from a woman in a white striped shirt, green pants, and glasses at a white table with a laptop, LEGO set, and small toys. The woman gestures with her hands, opens the laptop, and looks at the screen as the boy shifts his gaze downward. The camera remains static in a room with white and blue walls.

Two individuals (a boy and a woman) exhibit subtle movements (hand gestures, posture shifts) consistent with conversational locomotion.

The background (walls, door, table) shows no significant shifting or fluid motion; no fire, water, smoke, or wind effects are present.


A person in a black t-shirt plays a violin in a medium shot, then the camera zooms in to a close-up of the violin and their hands as they move the bow across the strings and press the fingerboard. The background is a plain, light wall.

The violin and bow are moving in controlled, discrete motions: the left hand presses strings while the right hand draws the bow across the strings. The violinist's hands exhibit precise locomotion typical of playing.

The background consists of a static plain wall with no shifting elements. No fire, water, smoke, or wind is present; ambient environmental motion is absent.


A person wearing a blue hoodie over a red shirt holds a hot dog, raises their right hand, brings the hot dog closer to their mouth, then opens their mouth wide. The camera remains static throughout.

A person is making hand gestures and adjusting their hood; motion is due to voluntary movement.

Background consists of static walls and door frame; no ambient environmental motion (e.g., fire, water, wind) observed.


A video opens with two individuals standing; one in a purple shirt (short hair, back to camera) faces another in a blue striped shirt and jeans. They shake hands, the camera zooming in on their clasped hands. The scene shifts to a second handshake between a person in a light blue lace-patterned sleeve and a person in a gray shirt, with a chair and water bottles visible in the background. The camera remains close-up on the handshakes, showing slight movement.

Two hands are shaking, showing a physical interaction between two people. The motion is due to the force applied during the handshake.

The background in both scenes (stone wall and office) is static; no shifting background elements detected. No fire, water, smoke, or wind present.


A person in a black suit holds a brown violin under their chin, moving a bow across the strings with their right hand while their left hand adjusts finger positions on the violin neck. The violin remains positioned in front of the person throughout the sequence, with the camera maintaining a static, medium shot focused on the upper body and instrument against a plain white background.

A person playing violin: moving arms and hands to bow and press strings.

No shifting background or fluid/environmental motion observed. Background is static white wall with fixed image.


A pair of hands adjusts numerous long, green palm fronds arranged radially on a white board, pressing them into place. The hands then reach for a small tool on a red-and-blue cloth to the left, preparing to manipulate the fronds further. The background includes woven green baskets and a patterned cloth. The camera maintains a steady top-down perspective throughout.

Hands are actively manipulating green structural elements (spokes) of a basket-like object, demonstrating intentional physical interaction with discrete solid objects.

Background elements (woven baskets, tiled floor) show no significant shifting or fluid motion. No fire, water, smoke, or wind is present.


A hand moves a small object across a table covered with magazines and parts, positioned next to a blue motorcycle. The motorcycle's front wheel and engine are visible as the hand manipulates the object. The camera maintains a close-up perspective with slight movement, focusing on the hand's motion near the table.

Discrete solid objects (hands) are interacting with newspapers, demonstrating intentional movement (picking up, adjusting papers) due to physical force.

The background elements (motorcycle, floor, static objects) show no uniform shifting or fluid/environmental motion (no fire, water, smoke, or wind).


A man in a gray polo shirt and black shorts stands on a platform in a gym, holding a barbell above his head. He lowers his body into a squat position, then rises back to an upright stance, repeating the motion. The gym background includes various exercise machines and equipment. The camera remains stationary throughout.

The man is the discrete object moving: stepping on/off a platform and raising arms due to his own physical effort.

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


A newborn baby, wrapped in a white blanket with pink trim and wearing pink pants, lies on a hospital bed. Initially still with eyes closed, the baby gradually moves, raising one hand and adjusting its position slightly. The camera maintains a top-down perspective with minimal movement, focusing on the baby's gentle motions against the white bed linens.

The newborn baby is the only discrete object exhibiting motion: hands, legs, and head shift with natural limb movements (e.g., arm raising, leg kicking, head turning), driven by internal physiological forces.

The hospital room background (bed frame, walls, medical equipment) shows no uniform shifting or environmental motion (no fire, water, smoke, or wind). All background elements are static, indicating no dominant ambient environmental forces.


The left side of the frame features a black background with animated teal and pink oval shapes numbered 1 and 2, as green dots sequentially move between them. On the right, a person’s hands hold a white marker, steadily interacting with an unseen object. The camera maintains a static split-screen perspective, focusing on the motion of the green dots and the hands without significant background detail.

The cat is moving via locomotion, and it is the only solid object with significant motion in the scene.

The background of the cat's video is static and there are no ambient environmental elements (fire, water, smoke, or wind) visible.


RAW CAPTION: Got it, let's break this down. The video starts with a skier on a snowy slope. The skier is in motion, approaching a jump. Then they jump, doing a trick where they hold the skis. Let's check the timeline.

First frame: skier is skiing down the slope, probably getting ready for a jump. Second frame: skier is in mid-air, maybe after the jump. Wait, the frames are:

[0.0] skier is on the snow, moving.

[1.4] skier is jumping, maybe taking off.

[2.5] skier is in the air, holding skis up.

[3.6] skier is still in air, maybe rotating.

[4.7] skier is landing, or in the process of landing.

Wait, the key points: skier (black outfit, skis) on snow, jumps, does a trick (holding skis vertically), then lands.

Appearance: skier in dark clothing, skis are visible. Number: one skier.

Motion: starts skiing, then jumps, performs an aerial maneuver (holding skis), then lands.

Background: snowy mountain, distant peaks, cloudy sky. But per rule e, minimal background unless essential. The background is just the setting, so maybe just mention "snow-covered slope" and "distant mountains" briefly.

Spatial: skier is moving from left to right? Wait, in the frames, the skier starts on the left side of the frame, moves towards the right, then jumps. Wait, no—wait, the video starts with skier on the left, then moving to the right, then the jump. So the skier is moving across the slope.

Camera perspective: the video is shot from a fixed position, looking down on the slope, maybe a static shot. The camera doesn't move much, so maybe "fixed perspective".

Putting it all together:

Chronological: skier (dark clothing, skiing) moves across snowy slope, launches into jump, holds skis vertically during aerial maneuver, and lands.

Check rules:

a) Motion in order: skier skiing, jumping, airborne trick, landing.

b) Appearance: dark outfit, skis.

c) Spatial: skier starts on left, moves right, jumps.

d) Camera: fixed, overhead? Wait, the video is filmed from a position that's elevated, so top-down. Wait, the first frame shows the skier below the camera, so it's a top-down perspective.

e) Background: mention "snow-covered slope with distant mountains" minimally.

f) Exclude text, names, etc.

So structure:

[0.0] Skier in dark clothing begins skiing down a snow-covered slope. [1.4] The skier launches into a jump, gaining height. [2.5] Mid-air, the skier holds skis vertically while performing a trick. [3.6] The skier continues airborne, maintaining the maneuver. [4.7] The skier lands on the slope after completing the jump. Camera maintains a fixed overhead perspective throughout.

Check if concise. Maybe shorten:

A skier in dark clothing skis across a snowy slope, launches into a jump, holds skis vertically during flight, and lands. The camera remains fixed overhead.

Wait, need to include chronological order of the actions. Let's make sure each step is in order.

First: skier starts skiing (position on slope).

Then: jumps.

Then: in air, holding skis.

Then: lands.

So:

A skier dressed in dark clothing skis down a snow-covered slope, then jumps and becomes airborne. While in mid-air, the skier holds their skis vertically, executing a trick before landing back on the slope. The camera captures this sequence from a fixed overhead perspective.

Wait, check if "dressed in dark clothing" is necessary. The rule says "briefly describe appearance and number (color, size, orientation)". The skier's clothing color is dark, so include.

Also, "number" is one skier.

"Size" might not be necessary since it's a person. But "dark clothing" is key.

So:

A single skier in dark clothing skis down a snow-covered slope, launches into a jump, holds skis vertically during flight, and lands. The camera remains stationary in an overhead position.

Wait, "launches into a jump" is from 1.4, then 2.5 mid-air. So:

The skier moves across the slope, jumps, so "launches into a jump" (at 1.4), then mid-air (2.5-3.6) with skis held vertically, then lands (4.7).

Another version:

At the start, a skier in dark clothing skis across a snowy

A skier moves down a snowy slope, performing a jump with clear bounding box tracking. The skier's motion includes skiing, airborne maneuver, and landing.

Background shows stationary snow-covered mountains and overcast sky with no uniform shifting. No fire, water, smoke, or wind-driven motion (e.g., swaying trees) detected.


A person with short dark hair, wearing a black tank top and sunglasses, sits while holding a martini glass with a cocktail in their left hand and a stack of papers. They adjust their sunglasses with their right hand, moving them down from their eyes. The background features chairs and a window; the camera remains static.

The main discrete solid object moving is the woman in the foreground (adjusting sunglasses and turning head). The man in the background is minimally moving but is not the primary focus.

The background (walls, window, furniture) shows no shifting or fluid motion. There is no fire, water, smoke, or wind to suggest ambient environmental motion.


A hand with pink nail polish uses a small tool to adjust gold earring studs mounted on pink pads within a white card. The hand moves the tool over the earring, then retracts, revealing the earrings. The camera maintains a top-down perspective throughout the sequence.

A hand with pink nail polish interacts with gold earrings on a display card. The hand moves to adjust or demonstrate the earrings, which are discrete solid objects.

The background consists of a static surface and a product card; no fluid environmental motion (fire, water, smoke, wind) is present. Background elements do not shift uniformly.


A large herd of black cattle moves left to right across a dry field, guided by a rider in red on horseback. The rider leads the herd, maintaining position ahead as the cattle follow in a loose formation. As the video progresses, individual cattle adjust direction, some veering toward a water source on the right. The camera pans right to track the herd’s movement.

Rider on horseback and herd of cattle (including calves) moving collectively as a group, driven by locomotion and guidance; all objects maintain clear, distinct bounding boxes with visible physical motion patterns.

No significant ambient environmental motion (e.g., fire, water, smoke, wind) observed. Background trees and ground are static, with no fluid or gaseous motion dominating the scene.


A small child in a white outfit with red accents sits on a person’s lap, holding and flipping through newspapers. The child leans forward to examine a page, continues turning the papers, and briefly looks down at the content. The adult, wearing a red shirt, is partially visible behind the child. The camera maintains a top-down perspective with slight movement.

Child's hands and head move while flipping and reading the newspaper.

Background (couch, floor) is static; no environmental motion (fire, water, smoke, wind) observed.


RAW CAPTION: Okay, let's see. I need to generate a concise chronological paragraph describing the video based on the provided frames. The user is an expert video captioner, so I have to follow all the rules they mentioned.

First, the main subjects are five people. They're all wearing yellow and purple, which are the dominant colors. Let me check the frames. In the first frame, they're standing in a line, all facing the camera. Then, in the next frames, they start moving their hands and bodies. The actions seem to be waving, pointing, and making gestures. The background is a bright blue sky with clouds and green hills, but the rule says to keep background descriptions minimal unless essential. Since it's a consistent background, maybe just mention it briefly.

The rules say to focus on motion and behavior in chronological order. So I need to list the sequence of actions. Let's look at the frames:

Frame 0: All five are standing, some waving, others with hands up. The person on the right has a purple wig.

Frame 1: More movement, like waving and pointing.

Frame 2: They're all moving their arms, some pointing towards the camera.

Frame 3: Gestures continue, maybe different directions.

Frame 4: More dynamic movements.

Frame 5: Similar to previous frames, continuing their gestures.

So the main actions are the group waving, pointing, and making hand gestures. They're all in a line, maybe standing close together. Spatial relationships: they're in front of the background, left to right order. The camera is probably static, but the user mentioned to note camera movement. The frames don't show camera movement, so maybe "fixed camera perspective" or "static shot".

Appearance: Five people, wearing yellow and purple. Specifics: purple wig on the right person, yellow hats and scarves. Wait, but rule f says exclude named characters or stylistic analysis. So maybe just say "five individuals in yellow and purple clothing" without specifics like the wig, unless it's essential for motion. Wait, the wig is part of their appearance, but maybe the rules allow it if it's necessary for understanding. Hmm, the user says "briefly describe their appearance and number (color, size, orientation)". So maybe mention that they're wearing yellow and purple, and the purple wig is part of their appearance, but since it's a distinctive feature, perhaps include it. But the rule f says exclude stylistic analysis, so maybe it's okay.

Wait, the example in the problem statement shows that the caption should include details like "yellow and purple clothing", but maybe not specific accessories unless they're part of the motion. Wait, the example given in the problem statement (the user's example) includes specific elements like the purple wig. But the rules say "exclude named characters or stylistic analysis". The wig is a stylistic element, but maybe it's necessary for description. Hmm, the rules say "exclude text recognition, named characters, or stylistic analysis". So maybe the purple wig is a stylistic element, so should I omit it?

Wait, the problem statement says: "b) Briefly describe their appearance and number (color, size, orientation)." So color is part of appearance. The wig is part of their appearance, but since it's a specific feature, perhaps it's okay to mention. Let me check the example given in the problem statement. The user's example shows that the description includes the purple wig. Wait, looking back, the user provided the example frames, which include the purple wig. So perhaps it's acceptable to mention the purple wig as part of their appearance.

Wait, but the rules say to exclude stylistic analysis. Is the wig considered stylistic? Maybe, but since it's a visual detail necessary for the description, perhaps it's allowed. Let's proceed.

Number of people: five. Colors: yellow and purple. One has a purple wig, others have yellow hats and scarves. But to be concise, maybe just say "five individuals wearing yellow and purple clothing, including a purple wig on the rightmost person".

Wait, but the user says to keep it concise. Maybe "five people in yellow and purple attire, with one sporting a purple wig" but need to check if that's too specific. Alternatively, just "five individuals wearing yellow and purple, including a purple wig on the right".

Now, the motion: they start by waving and gesturing. The chronological order would be that in the first frame, they are making hand movements, then continue to point, wave, and move their arms in different directions. The actions are sequential, so the caption should note that they wave, point, and gesture in a sequence.

The background is a bright sky with clouds and green hills, but as per rule e, keep it minimal. So maybe "against a bright sky and green hills" but only if

Five people are moving via hand gestures and body movements, which are discrete solid objects.

Background elements (sky, clouds, hills) are static with no fluid or wind motion. No ambient environmental dominance.


A person in a floral-patterned shirt and gray pants adjusts a floral bouquet on a white table with lace trim. The bouquet, featuring red roses, white blooms, and greenery, is positioned centrally. The person's hands move to rearrange the flowers, shifting them slightly, while other floral arrangements—including bright red roses in a glass vase and white flowers in a pink container—remain to the left. The camera maintains a static top-down view throughout.

Person's hands are moving to manipulate and arrange flowers (discrete solid objects), demonstrating intentional locomotion of physical entities.

Background elements (table, floral arrangements, wall) remain static with no uniform shifting or environmental fluid motion (fire, water, wind).


Six children stand in a line, each holding a recorder, positioned in front of a chalkboard. They begin playing, their hands moving rhythmically over the instrument holes as they blow into the recorders. Throughout the sequence, the group maintains their formation, with minor adjustments to their stances. The camera remains in a static position, with a slight leftward pan, capturing the performance from a frontal angle.

Discrete solid objects (people) are moving: their arms and bodies exhibit coordinated motion consistent with playing musical instruments (clarinets), indicating intentional physical movement.

Background elements (wall, floor) show no uniform shifting or fluid motion; no fire, water, smoke, or wind-dominated action present.


RAW CAPTION: Got it, let's break this down. The video starts with a desk setup: a monitor showing a blue-yellow pattern, various devices like a phone on a stand, a black box (maybe a speaker), a chair, etc. Then, at [1.2s], the monitor changes to a grainy image. Then at [2.5s], a hand enters from the bottom right, moving towards the monitor. The hand is near the bottom of the frame, and then it covers part of the monitor. The hand is light-skinned, and it moves up slightly, maybe adjusting something. Then the hand moves away, and the monitor goes back to the blue-yellow pattern. Wait, no, the next frame after the hand is the monitor showing an orange blur. Let me check the timestamps.

First frame: 0.0s, monitor has blue/yellow dots. Then 1.2s: monitor shows grainy (maybe a video feed), then 2.5s: a hand (light-skinned) comes from the bottom right, moving towards the monitor. The hand is in front of the monitor, covering part of it. Then at 3.5s, the hand is still there, then 4.5s, the hand moves away, and the monitor is back to the blue-yellow pattern? Wait, no, the third frame (2.5s) has the hand, then 3.5s: the hand is still there but maybe adjusted, then 4.5s: hand moves away, monitor shows the grainy image again? Wait, no. Let me list the frames:

[0.0] - monitor blue/yellow, desk items.

[1.2] - monitor shows a gray, grainy image (maybe a different video feed).

[2.5] - a hand enters from the bottom right, reaching towards the monitor (covers part of it).

[3.5] - hand is still in front, maybe adjusting something.

[4.5] - hand moves away, monitor shows an orange blur (maybe the next frame after adjusting).

[5.0] - hand moves away, monitor shows a greenish blur (wait, no, the last frame [5.0] shows the monitor with a grayish image? Wait, no, the video description is:

[0.0] - blue/yellow.

[1.2] - gray.

[2.5] - hand enters (covers part of monitor).

[3.5] - hand still there.

[4.5] - hand moves away, monitor shows orange.

[5.0] - hand gone, monitor shows greenish.

Wait, no, the user provided 6 frames, but the problem shows the video as a series of 5.5s. Let's check:

The user's input has:

<0.3s> - blue/yellow.

<1.4s> - gray (grainy).

<2.5s> - hand from bottom right (covering monitor).

<3.6s> - hand still there.

<4.7s> - hand moves away, monitor shows orange.

Wait, the timestamps: 0.3s, 1.4s, 2.5s, 3.6s, 4.7s. So five frames.

So, starting at 0.3s: monitor shows a colorful blue and yellow pattern. Then at 1.4s, the monitor changes to a grainy, grayish image. At 2.5s, a light-skinned hand enters from the bottom right, moving towards the monitor and covering part of it. The hand remains in front of the monitor at 3.6s. Then at 4.7s, the hand moves away, and the monitor displays an orange blur.

Now, the main subject is the hand. So describe the hand's motion: enters from bottom right, covers monitor, remains, then moves away.

Background: desk with monitor, phone, etc., but keep background minimal.

Chronological order:

At 0.3s: monitor shows blue/yellow pattern.

At 1.4s: monitor changes to grainy image.

At 2.5s: a light-skinned hand enters from bottom right, moves toward the monitor, partially covering it.

At 3.6s: hand remains in front of the monitor.

At 4.7s: hand moves away, monitor shows orange blur.

Now, spatial relationships: hand is in front of the monitor, at the bottom right.

Camera perspective: probably static, top-down or slightly angled, since it's a desk setup.

Exclude text, names, etc.

So the caption should be:

A light-skinned hand enters from the bottom right of the frame at 2.5 seconds, moving toward the

A hand moves discrete physical objects (e.g., mouse, green/white items) on the desk; these movements are solid, distinct, and driven by explicit physical forces (human locomotion).

The background (room walls, furniture) is static with no uniform shifting. The monitor displays changing digital patterns (e.g., blue noise, orange gradient), but these are not physical fluids or environmental phenomena (fire, water, smoke, wind) – they are computer-generated content, thus not ambient_environmental.


Close-up of a black oil filter drain plug being turned by a tool; then, a person's hands pour yellow oil from a silver container into the engine's funnel. The camera transitions from a close-up of the drain plug to a medium shot of the hands and container.

Discrete objects in motion include the person's hands manipulating the oil filter and oil container, as well as the oil container being tilted during pouring.

No shifting backgrounds or fluid/environmental motion (fire, water, wind) observed. The engine bay and vehicle components remain static relative to the frame.


RAW CAPTION: Okay, let's tackle this. The user wants a concise caption for the video. First, I need to follow all the rules they provided.

The video shows a birthday scene. There's a little girl in front of a cake with candles. The main subjects are the girl and the cake. The girl is wearing a white top and red skirt. She's sitting at a table. The cake is on a stand with three candles. The girl moves her hands, maybe reaching for the cake or reacting to the candles.

The text "That face" is there, but I have to exclude text recognition per the rules. So ignore that.

Chronological order: Start with the girl looking at the cake, then she reacts, maybe makes a face. The background has people behind her, but minimal description. The camera is static, maybe slightly shaky. Need to mention the spatial relationship: girl is in front of the cake, people behind her.

Check the rules: focus on motion and behavior. The girl's actions: she looks at the cake, then turns away, maybe blows or reacts. Her hands move. The cake is on a stand. The candles are colorful.

Need to keep it concise. Avoid mentioning the text, background details unless essential. The camera is static but maybe slight shake. The output should be in the specified format.

Wait, the example output has "A young girl in a white top and red skirt sits at a table, facing a large round cake with three candles on a white stand." Then describes her actions: she reaches toward the cake, then turns away, her hand motion. Background has people but minimal. Camera is steady.

So I need to structure it: first the setup (girl, cake, their positions), then the sequence of her actions (reaching, turning away, hand motion), mention the cake's appearance (size, color, candles), the people in the background but not detailed. Camera is static.

Wait, the user's example says "A young girl... sits at a table, facing a large round cake..." then her actions. So start with description of main subjects, then motion.

Make sure to mention the cake's color (light-colored), the candles (three, colorful). The girl's actions: she looks at the cake, moves her hands, possibly blowing or reacting. Then the camera is steady.

Check the rules again. Exclude text, so ignore "That face". Background minimal, so maybe just mention people behind her but not details.

Let me draft:

A young girl in a white top and red skirt sits at a table, facing a large light-colored cake with three colorful candles on a white stand. She reaches toward the cake with her hands, then turns her head away, her hand motion indicating a reaction. Behind her, two adults sit partially visible. The camera remains steady throughout.

Wait, the original video shows the girl making a face, which is the "That face" text. But per rule f, exclude text recognition, so don't mention the text. So focus on her facial expression as part of her behavior. Wait, the instruction says "describe the motion and behavior", so if she's making a face, that's part of her behavior.

Wait, the rules say "Focus primarily on the motion and behavior of main subjects". So her facial expression (the face) is part of the behavior. So maybe "she makes an expressive face, then turns away".

Check the first part: "A young girl in a white top and red skirt sits at a table, facing a large light-colored cake with three colorful candles on a white stand. She reaches toward the cake with her hands, then makes an expressive face before turning away. Behind her, two adults sit partially visible. The camera remains steady throughout."

But need to be concise. The example output in the user's problem statement for the same video (the user provided the video and the example output) would be a bit shorter.

Wait, the user gave the example where the caption is "A young girl in a white top and red skirt sits at a table, facing a large round cake with three candles on a white stand. She reaches toward the cake, turns her head away, and moves her hands expressively. Behind her, two adults sit partially visible. The camera is steady."

So in the caption, mention the order of her actions: reaches toward cake, turns head away, moves hands. The cake's description. The background people. Camera is steady.

So for the given video, the girl is moving her hands, then making a face. So "reaches toward cake, then turns head away, making an expressive face while moving her hands."

Wait, the video shows the girl looking at the cake, then she makes a face, maybe blowing or reacting, and her hand movements.

So putting it all together:

A young girl in a white top and red skirt sits at a table, facing a large light-colored

The child and the adult holding the child are moving; the child is blowing out candles with visible head movements and body shifts.

The background (window blinds, framed picture) is static and shows no shifting. No fire, water, or smoke is present.


A bearded man in a maroon long-sleeve shirt holds a sunburst-colored bass guitar with a black strap, standing in front of a drum set. He adjusts his grip on the bass neck, looks down, then lifts his head to face the camera while maintaining his hold on the instrument. The camera remains static, capturing a medium shot of the subject against a neutral background.

The man's hands are moving to play the bass guitar (plucking/strumming), representing discrete solid-object motion.

Background is static (plain wall and drum set); no fluid/environmental motion detected (fire, water, wind, or wind-driven swaying).


A person wearing a striped beanie and dark clothing spins the front wheel of a bicycle while standing in a workshop. Another individual in dark attire walks past the bike from the right side of the frame to the left. The camera remains stationary throughout.

A person is actively moving around and manipulating a bicycle (e.g., adjusting components, handling parts). The bicycle wheel appears to be rotating or being adjusted by the person's actions.

Static cardboard boxes and structural elements (ceiling, walls) show no uniform shifting or environmental motion (e.g., smoke, water, fire). No fluid or gaseous elements dominate the scene.


A person with a watch lifts a silver metal coffee pot with a black handle from a circular sandy surface where multiple identical pots are arranged, pours liquid into a pink disposable cup held in their other hand, then places the cup on a metal counter before returning the pot to the sand. The camera maintains a top-down perspective, slightly shifting to follow the pouring and placement motions.

Discrete objects include the person's hands (pouring coffee), metal cups (being moved), and the coffee itself (transferred from cup to cup). These movements are driven by physical actions like pouring and handling.

The background (counter, brown surface) shows minimal shifting; no fire, water, smoke, or wind dominates the scene. The brown substance is static and part of the setup, not a fluid motion.


RAW CAPTION: Got it, let's tackle this. First, the video starts with a person on roller skates. They're wearing a blue shirt, dark shorts with a pattern. Then, another person in a blue shirt and black shorts comes into view. Wait, the main subject is the first person. Let's check the sequence.

At the start, the person in blue shirt and floral shorts is skating on a paved path. Then, another skater in blue shirt (but maybe different) and black shorts is near. Wait, the video shows a person roller skating down a path. Then the camera moves closer to show their lower body. Then they turn around, and another skater is visible. Need to describe in chronological order.

First frame: person (blue shirt, dark shorts with white flowers) on roller skates on a paved road, with grass on sides. Then, the camera follows them as they skate. Then, a close-up of their legs (roller skates with red wheels). Then, they turn around, and another skater in blue shirt and black shorts is to their left. Wait, the video segments:

0.0s: person in blue shirt (text on shirt), dark shorts, roller skates (red wheels) on path, grass on right. Another person in blue shirt in background.

1.0s: camera focuses on the skater, shows their lower body, the path. Then they turn around, so the camera follows their movement.

2.0s: close-up of the skater's legs, showing the roller skates, and another person (black shorts) on the right.

3.0s: the skater is now moving away, back view. Another skater is to the left (blue shirt, black shorts).

4.0s: the first skater continues, another skater (white shirt, black shorts?) is visible on the left.

Wait, need to focus on main subjects. The main subject is the person in blue shirt with floral shorts, roller skating. Then there's another skater.

Chronological order: The person in blue shirt and dark shorts with white flowers is roller skating down a paved path. The camera follows from behind as they move, then shifts to a close-up of their legs with red-wheeled roller skates. They then turn around, revealing another person in a blue shirt and black shorts standing to their left. The camera maintains a steady perspective from behind the skater as they continue moving forward, with another skater visible in the foreground to the left.

Wait, the rules say concise. Let's structure:

- Start with main subject: a person in a blue shirt and dark floral shorts roller skating on a paved path.

- Then, the camera follows, showing their movement.

- Close-up on their legs (red wheels) as they skate.

- They turn, and another skater in blue shirt and black shorts is now to their left.

- Then they continue, with another skater to the left.

Wait, the video has these frames:

0: person skating, background grass.

1: camera angle shifts to focus on their lower body, path.

2: close-up of legs (roller skates with red wheels), another person in black shorts on the right.

3: person turns around, now moving away, other person (blue shirt, black shorts) is to the left.

4: person continues, another skater (white shirt, black shorts?) is on the left.

Wait, the second person in frame 2 is wearing black shorts. So the main subject's appearance: blue shirt, dark shorts with white flowers, roller skates (red wheels). Then, when they move, another skater (blue shirt, black shorts) is visible to their left.

So the caption should be:

A person in a blue shirt and dark floral shorts roller skates down a paved path, with red wheels on their skates. The camera follows closely behind, showing their movement, then shifts to a close-up of their legs as they skate. The person turns around, revealing another individual in a blue shirt and black shorts standing to their left. The scene continues with the main subject skating away, while another skater in a white shirt and black shorts appears to the left. The camera maintains a steady perspective from behind, capturing the motion of the skaters on the path.

Wait, but need to keep it concise. Let's check the rules: concise, chronological.

Let's make it:

A person in a blue shirt and dark floral shorts roller skates along a paved path, with red-wheeled skates. The camera follows behind, then focuses on their lower body as they move. The person turns around, revealing another individual in a blue shirt and black shorts to their left. They continue skating away, with another skater in a white shirt and black shorts visible in the foreground. The camera maintains a steady follow perspective from behind

The primary moving object is a person roller skating. The roller skater moves along the path, approaching the camera and then moving away. Another person (in orange) is briefly visible but appears to be stationary or moving minimally.

The background (paved path and grassy areas) is static and does not show any shifting or fluid motion. There are no elements of fire, water, or smoke. The motion in the scene is primarily the movement of the roller skater.


A child with short hair and a red shirt sits at a wooden table, holding an open newspaper with both hands and reading. The child then uses their right hand to flip the newspaper’s page. Chairs with light and brown seats are visible on the tiled floor in the background. The camera remains stationary, capturing the scene from an angle that focuses on the child and the newspaper.

A person's hands and a newspaper are moving; the newspaper is being flipped through manual manipulation, indicating discrete solid-object motion.

Background elements (chairs, tiled floor) show no uniform shifting; no fire, water, smoke, or wind-driven motion observed.


A person in a dark blue and white jacket holds a baby wearing a light-colored patterned onesie. The baby brings a hand to its mouth while the person supports its body, then the person moves one hand to adjust the baby’s head. Background elements include red and yellow structures. The camera remains static, focusing closely on the interaction.

An adult's hands are feeding a baby, causing discrete movement of the baby's head and the adult's hands as they interact.

The background features stationary colorful blocks and furniture with no fluid motion (fire, water, smoke) or uniform shifting indicating environmental influence.


RAW CAPTION: Got it, let's tackle this caption. First, the video shows a person cutting a watermelon. The main subject is the person's hands and the watermelon. The watermelon is green with dark stripes, large, on a wooden cutting board. The person uses a knife to slice it. The sequence: they hold the watermelon, position the knife, cut, then lift the half. Need to describe motion chronologically.

Check the rules: focus on motion, appearance, spatial relationships, camera perspective.

Start: Hands place a large green-striped watermelon on wooden board. Then, hands use a knife to cut the watermelon vertically. Next, lift the cut half to reveal the red interior. The camera is close-up, top-down maybe? Wait, the first frame shows hands, then the cutting action. The background is minimal, so keep that out.

Applies rules: chronological, motion, appearance (green stripes, red inside), spatial (on board, knife to the left?), camera perspective. The text in the video is not to be included.

So, structure:

A person's hands place a large green-striped watermelon on a wooden cutting board. The hands then position a knife to the left of the watermelon and slice it vertically. The knife cuts through the watermelon, separating it into two halves; the person lifts one half to display the red interior.

Check camera: the video is close-up, focusing on the hands and watermelon. The camera might be top-down or slightly angled, but the movement isn't much. The description says "close-up" in the context.

Wait, the output needs to be a paragraph. Let's make it concise.

Possible draft:

A person's hands place a large green watermelon with dark stripes on a wooden cutting board. The hands position a knife to the left of the watermelon and slice it vertically, separating the fruit into two halves. The person then lifts one half, revealing the red interior.

Check rules: exclude text, named characters, stylistic analysis. So no mention of the text. Background minimal, so just focus on the main action.

Yes, that should work. Let's confirm:

- Motion: placing, slicing, lifting.

- Appearance: green watermelon with stripes, red interior.

- Spatial: on cutting board, knife to left.

- Camera: close-up (since it's focused on the hands and watermelon).

Wait, the camera perspective: the video shows a top-down view? The first frame shows the watermelon on the board, so maybe the camera is above, looking down. But the rules say conclude with camera perspective and movement. The movement here is minimal, maybe static close-up.

So the caption should end with "The camera maintains a close-up, static perspective focused on the watermelon and hands."

But the example might not need that if it's clear. Wait, the rules say: "Conclude with the camera perspective and movement (e.g., top-down, pan left, slight shake)."

In the video, the camera seems to be a close-up, static shot. So maybe "The camera remains in a close-up, top-down perspective throughout."

Let me check the frames: first frame shows the hands holding the watermelon, then the knife, then cutting. The camera angle is likely top-down or slightly angled, but the main view is close on the action.

So putting it all together:

A person's hands place a large green watermelon with dark stripes on a wooden cutting board. The hands then position a knife to the left of the watermelon and slice it vertically, separating it into two halves; the person lifts one half to reveal the red interior. The camera maintains a close-up, top-down perspective focused on the action.

Wait, but the rules say "briefly describe their appearance and number". The watermelon is one, the person's hands. So "a person's hands" is okay.

Also, "in front of" or spatial relationships: the watermelon is on the board, knife is to the left of the watermelon.

Let me revise for conciseness:

A person’s hands place a large green-striped watermelon on a wooden cutting board. They position a knife to the left and slice it vertically, separating the watermelon into two halves; one half is lifted to show the red interior. The camera stays in a close-up, top-down view.

Yes, that's concise. Check if it follows all rules:

a) Motion: placing, slicing, lifting.

b) Appearance: green-striped, red interior.

c) Spatial: knife to the left of watermelon on board.

d) Camera: close-up, top-down.

e) Background minimal.

f) No text recognition, etc.

Good.
</think>

<caption_output>A person's hands place a large green-striped watermelon on a wooden cutting board. They position a knife to the left of the watermelon and slice

Discrete solid objects include the watermelon (rotated and sliced), the knife (moved to cut), and the person's hands (positioning and manipulating the watermelon).

The background elements (table, person's apron, cutting board) remain static with no uniform shifting, and there are no fire, water, smoke, or wind elements present.


The video opens with hands adjusting a snowman-shaped container featuring a black top, red ribbon, and a silver face with black eyes and an orange nose. The scene transitions to a woman in a purple shirt seated at a table, holding the container. The camera shifts from a close-up of the container to a medium shot of the woman interacting with it.

A person (woman) is visible, making subtle hand movements and facial expressions; a decorative object (snowman-themed item) is held and occasionally repositioned by hands. These are solid, distinct objects with motion due to human locomotion/interaction.

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


A baby seated in a high chair with a patterned bib is fed by a hand entering from the right, which offers a spoonful; the baby opens their mouth, consumes the food, and closes their mouth as the spoon is withdrawn. The baby remains seated, looking toward the window. The camera maintains a steady close-up on the feeding action, with minimal background visible.

A hand holding a spoon moves toward the baby's mouth, and the baby's mouth moves to consume food. These are discrete solid objects (spoon, baby's mouth) interacting via explicit physical forces (feeding action).

The background features a window with greenery outside; no significant shifting or fluid/environmental motion (fire, water, smoke, or strong wind) is observed. Background elements (window frame, grass) remain static throughout.


A person wearing a light gray shirt, dark shorts, and a helmet runs toward a black skateboard, steps onto it, and begins skating across a concrete skate park. They move toward a ramp, approach its edge, and ride up the incline. The camera follows the skater’s movement steadily.

A skateboarder (solid, distinct object) moves across the scene by pushing off the ground and riding the skateboard, demonstrating explicit locomotion physics.

The background elements (ramps, trees, fences) remain stationary with no shifting or fluid motion (fire, water, wind).


A man in dark clothing plays violin, moving his bow and arms rhythmically while standing on a sidewalk. To his right, a person in a blue coat bends over an open case on the ground, then stands and walks away. Pedestrians pass by in the background. The camera remains stationary.

A violinist (discrete object) performs with arm and bow movements; a person in purple bends, stands, and walks away (discrete locomotion). Pedestrians in the background move independently due to walking.

No dominant fluid/environmental motion (fire, water, smoke, wind). Background elements (buildings, signs, sidewalk) are stable with no uniform shifting or fluid dynamics.


A pair of light-skinned hands adjusts dark braided hair on a scalp, pulling and repositioning individual braids methodically. The hands move across the hair, working to tighten or organize the braids. The camera maintains a close-up perspective focused on the hands and hair, with minimal movement.

Discrete solid objects (hands and hair) are moving: hands perform precise, intentional braiding motions on hair strands.

No shifting background elements; no fire, water, smoke, or wind motion detected. Background features a static colorful patterned cloth.


A person in dark clothing moves a rectangular wooden piece onto a workbench, positions it within a partially assembled wooden frame, and uses a hammer to tap a smaller wooden component into place. The workshop background includes tools mounted on the wall and a workbench with materials. The camera remains static, capturing the action from a side angle.

A person moves around the workshop, adjusting a wooden board on a workbench and using a hammer to strike it, demonstrating discrete solid-object locomotion and tool use.

The workshop background (tools on wall, workbench, shelves) remains stable with no uniform shifting or fluid/environmental motion; no fire, water, smoke, or wind present.


A person in a blue and red shirt sits at a table with a blue tablecloth featuring card designs, adjusting a multi-layered structure made of playing cards. They lean forward, then stand and move around the table, interacting with the card structure. The kitchen background includes a stove and cabinets. The camera follows the person's movements with slight shifts and a steady perspective.

A person manipulates a card pyramid structure and a water bottle; hands move to adjust cards, lift arms, and pour water onto the pyramid, showing explicit physical forces (locomotion, collision, pouring action).

Background elements (oven, cabinets) remain stable with no uniform shifting. No dominant fluid/environmental motion (fire, water, smoke, wind) observed; water pouring is a controlled event, not uncontrolled fluid motion.


A white sedan moves forward from within a yellow container truck, gradually exiting the rear of the container onto a road. The car’s taillights remain illuminated as it advances, with the yellow grated interior of the container visible in the foreground. The vehicle is centered in the frame, moving directly toward the camera, which maintains a fixed perspective from inside the container, capturing the car’s progression onto the external roadway.

A white car is moving backward relative to the container (being driven out), and the container door is opening.

The background (container walls and static outside environment) is static; no shifting backgrounds or fluid/environmental motion (fire, water, wind) observed.


A person in a black shirt, black shorts with white stripes, and a cap stands at a kitchen sink, facing away. They turn slightly to the right as a second person in a light-colored top with dark patterns and dark pants enters from the right, approaching the first person. The first person gestures with their right hand toward the second person, who stands beside them facing forward. The scene occurs in a kitchen with wooden cabinets and a red wall, with the camera remaining static throughout.

Two people (a man in black shirt/shorts and a woman in light top) move: the man turns from the sink to interact with the woman, who enters from the right and approaches the sink area.

The kitchen background (cabinets, sink, red walls) remains static with no shifting or fluid motion. No fire, water, smoke, or wind is present.


RAW CAPTION: Got it, let's break down the video. First, the main subject is a child in a red shirt and dark pants. The video starts with the child moving around. There's a red toy, maybe a play mat or something, on the floor. The child is interacting with it—picking it up, maybe dragging it. The background has a TV showing something, but we don't need to focus too much on that. The room is dimly lit with a carpeted floor. The child moves from the left side towards the right, then maybe back. The camera is probably stationary but maybe has a slight shake. Let's structure the caption:

Chronological order: Child in red shirt and dark pants is seen moving across the carpeted room. Initially, they approach a red cylindrical toy on the floor, pick it up, and carry it a short distance, then place it back. The child continues moving around the room, with a television visible in the background. The camera remains relatively fixed with minor movement, capturing the scene from a low angle.

Wait, need to check rules. Focus on motion and behavior chronologically. Appearance: red shirt, dark pants, child. Spatial: toy is on floor, child moves around. Background minimal. Camera perspective: low angle? The video description says "top-down" in the rules, but the video shows a room, so maybe not top-down. Wait, the user says "conclude with camera perspective and movement". The video is a bit shaky, maybe handheld.

Wait, the example in rules: "conclude with the camera perspective and movement (e.g., top-down, pan left, slight shake)."

So, in the video, the camera is probably handheld, slight shake. Let's see:

A child in a red shirt and dark pants moves across a carpeted living room floor. The child picks up a red cylindrical toy, carries it a short distance, and places it back down. The child then continues to walk around, passing near a television displaying moving images. The camera remains stationary with slight shake throughout the sequence.

Wait, but need to check the actual frames. The first frame: child is near a red object. Then moves, picks up the red toy (maybe it's a roll of something, like a play mat), walks to the right, places it down. Then in the next frames, the child is moving again. The background has a TV, but minimal background description.

So, concisely: A child wearing a red shirt and dark pants moves around a carpeted room, interacting with a red cylindrical toy on the floor. The child picks up the toy, carries it a short distance, and sets it down. The television in the background displays changing images. The camera maintains a fixed position with minimal shake.

Check rules: focus on motion and behavior chronologically. Yes: child moves, picks up toy, carries, places down. Appearance: red shirt, dark pants, child. Spatial: toy on floor, child moves around. Background minimal (TV is there but not emphasized). Camera: fixed with slight shake.

Make it concise. Let's try:

A child in a red shirt and dark pants walks across a carpeted room, picking up a red cylindrical toy from the floor, moving it slightly, then placing it back. The child continues moving around the space as a television in the background displays moving images. The camera remains stationary with minor movement throughout.

Wait, "picking up a red cylindrical toy from the floor, moving it slightly, then placing it back"—does that fit? Let's check the frames:

Frame 0: child near red object (maybe the toy is on the floor).

Frame 1: child steps towards it.

Frame 2: child picks it up (the red toy is held).

Frame 3: child moves with it.

Frame 4: child places it back down.

Yes. So the sequence is: approach, pick up, move, place back.

So, final caption:

A child wearing a red shirt and dark pants moves a red cylindrical toy across a carpeted floor, picking it up, carrying it briefly, and setting it back down. The child then walks away as a television in the background displays changing images. The camera stays fixed with slight shake during the sequence.

Check if it's concise. Let's see if we can shorten.

"A child in a red shirt and dark pants picks up a red cylindrical toy from the carpeted floor, carries it a short distance, and places it back. The child then walks around the room, with a television displaying moving images in the background. The camera remains stationary with slight shake."

Yes, that's good. No mention of text, names, etc. Spatial relationships: toy is on floor (carpeted floor). Background minimal (TV is there but not much detail). Camera: fixed with slight shake.

I think that's the structure.
</think>

A child in a red shirt is the primary moving object, performing locomotion (walking, turning) and manipulating a long red object (likely a toy baton). The object's motion is explicitly driven by the child's physical actions and collisions with the floor.

The background (walls, TV, furniture, carpet) remains stationary with no uniform shifting or environmental fluid effects (fire, water, smoke, wind). All static elements maintain consistent positions throughout the clip.


Three girls stand at the edge of a pool: the rightmost wears a purple dress with a yellow headband, the middle girl wears a pink swimsuit and blue cap, and the left girl wears a pink swimsuit. They sequentially jump into the pool—first the girl in purple, then the middle girl, followed by the left girl—generating splashes. The camera remains stationary, capturing the action from a side angle.

Three distinct girls (discrete solid objects) run along the pool deck and sequentially jump into the water. Their motion involves running (locomotion) and jumping (collision with water), tracked by clear bounding box movement.

The background (white wall, green bushes, paved deck) shows no shifting or uniform motion. Water splashes from the pool are secondary effects of the girls' jumps, not dominant environmental motion per the Ambient Rule.


Two individuals stand near a water-filled area bordered by a stone wall and vegetation; the person in a green shirt and blue shorts holds a fish, extending it toward the camera, while the person in a purple shirt with "CB" visible on the chest turns to observe. The camera slightly shifts to focus on the fish being presented, capturing the interaction between the individuals as the green-shirted person moves the fish closer to the lens.

Two individuals (discrete solid objects) are moving: the person in the green shirt holds a fish, while the person in the purple shirt interacts with the other individual (e.g., gestures, turning). Motion is driven by explicit physical actions (holding, gesturing).

Background elements (rocks, vegetation) show minimal shift; no dominant fluid or wind-driven motion (e.g., flowing water is not the primary motion focus, and environmental motion is negligible).


RAW CAPTION: Okay, let's see. I need to generate a caption for this video. The user provided the video frames, and I have to follow the rules. First, the main subject is a person in a red shirt with yellow gloves. They're handling a white object, maybe a washing machine or something. The video starts with the person pushing the object, then moving it.

Wait, the first frame shows the person in red pushing something. The second frame, they're lifting the white object. Then the next frames show them moving it around. The person is wearing yellow gloves, which stand out. The background is minimal, maybe a laundry room? But I should keep background descriptions minimal.

I need to mention the motion chronologically. So step by step: the person pushes the object, then lifts it, then moves it. The appearance: red shirt, yellow gloves, white object. Spatial relationships: maybe the person is in front of the object? Or the object is being moved into a machine? The last frame shows the person moving the object away.

Camera perspective: it's a bit shaky, handheld maybe. The video is shot from a close angle, following the action. The camera movement is probably handheld with slight shake.

Rules say exclude text recognition and named characters. So no mention of the washing machine brand or anything. Just describe the actions.

Let me structure it: A person in a red shirt and yellow gloves lifts and moves a white object, possibly a washing machine, from a seated position. The camera follows the motion with slight shake, maintaining close focus on the hands and object.

Wait, check the frames again. The first frame is the person pushing, then lifting, then moving. The video starts with the person pushing the object, then lifting it up, and then moving it. The object is white, maybe a washing machine top. The person's hands are in yellow gloves. The background is blurred, so minimal description.

So the caption should be: A person wearing a red shirt and yellow gloves lifts and maneuvers a white appliance, shifting it in place. The camera follows the motion closely with slight shake, focusing on the hands and object against a blurred indoor background.

Wait, but the user said "briefly describe their appearance and number". The person is one, red shirt, yellow gloves. The object is white. The spatial relationship: the person is handling the appliance, maybe moving it into a machine. But maybe the background is just a laundry room, but minimal.

The output should be a concise paragraph. Let me make sure it's chronological. Start with pushing, then lifting, then moving.

So: A person in a red shirt and yellow gloves pushes a white object, lifts it upward, and shifts it sideways. The camera maintains a close, slightly shaky perspective on the hands and object throughout.

Wait, the first frame shows the person pushing, then the next frame lifting, so the motion is pushing, lifting, moving. The object is white, maybe a washing machine or dryer. The person's arms are visible, red shirt, yellow gloves.

The caption should mention the motion sequence. Let me check the rules again.

Focus on motion and behavior in chronological order. So "A person wearing a red shirt and yellow gloves pushes a white object, lifts it upward, and moves it sideways. The camera remains close to the action with slight shake."

But need to check if it's a washing machine. Wait, in frame 0, the person is pushing something white, maybe a dryer. Then in frame 1, they lift a white sheet or cover. Hmm, the second frame shows the person lifting a white object, maybe a sheet or part of the appliance.

Wait, the video might be someone putting clothes into a washing machine. But the user says to exclude named characters and text, so no mention of what the object is. Just describe the action.

So: A person in a red shirt with yellow gloves lifts a white object from a machine, then moves it upward and sideways. The camera follows the motion closely with slight shake, focusing on the hands and object.

But need to check the exact sequence. The first frame is pushing, then lifting, then moving. Let's see:

Frame 0: person in red pushes white object.

Frame 1: hands in yellow gloves lifting white object.

Frame 2: same action.

Frame 3: moving the object.

So the motion is pushing, then lifting, then moving it. Maybe "A person in a red shirt and yellow gloves pushes a white object, lifts it upward, and shifts it sideways. The camera stays close to the action with slight shake."

But the rules say "chronological order" so the sequence is pushing, then lifting, then moving.

Yes, that's right.

Now, check the output format. Must be in <caption_output> tags.

Also, the background should be minimal. The video shows an indoor setting, but since it's

A person in red clothing with yellow gloves manipulates a white object (possibly a container or device), with visible hand movements and interaction with a white substance (likely steam or powder).

Background elements (white structure, surfaces) show no uniform shifting; no dominant fire, water, or smoke motion observed.


A person in a blue shirt and blue shorts sits on a bed with a red floral-patterned cover, holding a brass trombone. They play the instrument, then adjust the trombone’s slide, moving the bell closer to the camera. The background features a white wall and a small piece of furniture. The camera remains steady, capturing the subject’s actions from a frontal perspective as the trombone moves toward the lens.

The trombone slide is being moved by the person's hand in a deliberate manner to change pitch; minor head/body movements observed.

Background (wall, chair) is static; no fire, water, smoke, or wind present.
