RAW CAPTION: Got it, let's break this down. The video starts with a close-up of a Chinese character on a light background. Then it shifts to a park scene with a person practicing Tai Chi. The first part shows the character moving, so I need to note the transition from the text to the person. The main subject is the person in the park, doing Tai Chi movements. The video is in black and white, so color isn't an issue. There's another person in the background. The camera seems to move from the close-up of the text to the park scene, then maybe a slight pan to show the person's movements. Let's structure it chronologically: start with the text, then the park scene with the person. Mention the person's actions (practicing Tai Chi), their appearance (black clothing, maybe), and the spatial relationship (another person in the background). The camera movement: starts close-up, then transitions to the park, maybe pans to show the person's movements.

Wait, the first frames are the Chinese character (which is part of the text), then it changes to a park. So the video sequence: first, the text (but according to the rules, exclude text recognition, so maybe just describe the transition from the text to the person). Wait, the instructions say "Focus primarily on motion and behavior of main subjects". The main subject after the text is the person in the park. So the video starts with a close-up of a blurry Chinese character, then transitions to a black and white outdoor scene where a person in dark clothing practices Tai Chi movements, with another person in light clothing in the background. The camera moves from the text to the park, then maybe a slight pan to follow the person's movements.

Let me check the rules again. Rule a: motion and behavior of main subjects. So the main subject is the person practicing Tai Chi. The first part is the character, which is part of the opening, but the task is to describe the video. The video starts with the character (but we don't recognize text, so just note the motion of the character as it appears? Wait, the first frames show the character changing, maybe it's moving or zooming. Then it cuts to the park scene. So the video sequence is:

- Initial frames: close-up of a Chinese character on a light background, the character appears to be rotating or shifting, making the text blurry.
- Then transitions to a black and white park scene: a person in dark clothing is performing Tai Chi movements, with another individual in light clothing in the background, also moving or in a pose. The camera moves from the close-up of the character to a wider shot of the park, then pans slightly to capture the Tai Chi practitioner's motion.

But according to the rules, exclude text recognition, so we don't mention the text, but describe the motion. The Chinese character is changing (blinking, moving), so maybe the character is moving in the frame. Then the scene shifts to the park. So the chronological order: first, the character's motion (as it's displayed), then the park scene with people.

Wait, the first four frames show the character: frame 0 is "大", frame 1 is "中", frame 2 is "道", frame 3 is "道" with a different character? Wait, the text says "TAI-CHI-CHUAN: L'ECOLE DU BIEN-ETRE", so the Chinese characters are related to Tai Chi. The video starts with these characters, then cuts to the park. So the caption should start with the character display, then the park.

But rule b: describe appearance and number. The characters are black on light, maybe. Then the park has two people: one in dark clothing (practicing), one in light (background).

Let me draft:

The video begins with a close-up of a large, bold black Chinese character on a pale background, which shifts and blurs across frames. The scene transitions to a black-and-white park setting where a person in dark clothing performs Tai Chi movements, their body in fluid motion, while another individual in light clothing is visible in the background, also engaged in similar posture. The camera shifts from the close-up text to a wider shot of the park, panning slightly to follow the primary subject's actions.

Wait, but check rule e: minimal background descriptions. The park is background, but essential? The park has trees, so maybe just mention park setting. Also, rule d: camera perspective. Initial is close-up, then wider shot. The camera movement: from the close-up text (top-down? No, it's a close-up on the character), then transitions to a wider shot, panning.

Wait, the first part: the character is displayed in the frame, the camera is focusing on it. Then it transitions to the park scene. So

A person in traditional attire performs martial arts movements (e.g., kicking, stances) while other individuals stand in the background. All movements are consistent with physical locomotion or explicit force application.

Background elements (trees, ground) show no uniform shifting or fluid motion. No fire, water, or smoke present; trees remain static relative to the scene.


A female trombone player in a white shirt with pink accents and dark pants moves the slide of her instrument, while a male saxophonist in a white shirt and black tie presses keys on his saxophone. The trombone player is positioned to the left of the saxophonist, with other musicians visible in the background. The camera remains static with minimal movement.

Two musicians (violinist and guitarist) exhibit discrete movements: violinist's bowing arm motion and head swaying; guitarist's strumming and body shifts while playing.

Background shows stationary dark walls and stage elements with no shifting or fluid motion (e.g., fire, water, smoke, wind).


A young child in a red and white striped shirt with a bib sits in a high chair featuring a black and yellow plaid back. The child eats from a white tray holding pizza slices, a bowl of greens, and scattered food, bringing food to their mouth, then looking up and moving their hand toward the tray. The camera remains static, capturing the scene from a frontal angle.

The child (a solid object) is moving minimally with head and hand movements due to eating and looking around.

Background is static with no shifting walls or fluid/environmental motion (fire, water, wind).


RAW CAPTION: Got it, let's tackle this captioning task. First, I need to observe the video. The main subject is a man in a gym. He's wearing a gray shirt and dark shorts, lifting a barbell. Let's break down the sequence.

In the first few frames, he's holding the barbell in a lunge position. Then he's lifting it up, maybe doing a deadlift or a similar exercise. The camera seems to pan from left to right, showing him moving towards the right side of the frame. The background has weights and gym equipment, but I should keep background minimal.

Chronological order: He starts in a lunge position, then lifts the barbell upwards. Then the camera moves to show him from another angle, maybe a side view. Wait, the video shows him first in a position where he's lowering the barbell, then lifting it. Wait, the frames: [0.0] he's in a lunge with barbell low, then [1.4] he's lifting it up, [2.5] he's raising it, [3.6] he's at the top, then [4.7] he's moving towards a squat rack? Wait, the last frame (4.7s) shows him with the barbell near a squat rack, so he might be transitioning to a different exercise.

Wait, the video shows the man performing a barbell lunge, then moving towards a squat rack. Let's check the frames:

Frame 0: He's holding the barbell in a lunge stance, knees bent, barbell on the ground? Wait, no, the barbell is in his hands. Wait, no, in the first frame, he's holding the barbell with both hands, maybe in a deadlift position? Wait, the first frame shows him with the barbell extended forward, like a deadlift starting position. Wait, no, the video shows him doing a lunge with the barbell. Let me think again.

Wait, the first frame: he's standing with the barbell, one foot forward (lunge), knee bent. Then he lifts the barbell up, then lowers it. Wait, no, in frame 0.0, he's holding the barbell in a lunge position (front foot forward), then in frame 1.4, he's lifting it up (so maybe a front squat or something), then frame 2.5 he's higher, frame 3.6 he's lowering it, then frame 4.7 he's near a squat rack. Wait, the camera perspective: starts at a side view, then pans to another angle.

Wait, the first four frames show him from a slightly side angle, then frame 4.7 shows him from a more direct side (facing the camera). So camera movement: the camera pans from left to right, showing him moving from one side of the gym to the other.

Wait, the main points: a man in gray shirt, dark shorts, lifts a barbell while performing lunges, then moves towards a squat rack. Camera starts left, pans right.

Now, rules: focus on motion in chronological order. So start with his position, then action, then transition.

Main subject: one man, gray shirt, dark shorts, holding a barbell. He performs a lunge, lifts the barbell upward, then moves toward the squat rack. Camera pans right.

Check background: minimal, mention if essential. The background has a brick wall, weights, but maybe not necessary.

Let's draft:

A man in a gray shirt and dark shorts lifts a barbell in a lunge position, raising it upward before stepping backward toward a squat rack; the camera pans right to follow his movement.

Wait, but let's check the sequence. First frame: he's in a lunge with barbell, then he lifts the barbell (so the motion is lifting from the ground?), wait no, the barbell is held with hands. Wait, in the first frame, the barbell is close to his legs, like he's in a lunge position with the barbell, then he lifts it up. So his motion is lifting the barbell from a lunge stance.

Wait, the video shows him in a lunge, then lifting the barbell upward (so the barbell is raised), then he might be transitioning to a different exercise. Wait, the frames: [0.0] he's holding the barbell at hip level in a lunge, then [1.4] he's lifting it up to chest level, [2.5] higher, [3.6] lower, then [4.7] he's near the squat rack, so maybe he's lowering the barbell and moving to the rack.

Wait, the video might be showing a deadlift variation. But

A man is lifting a barbell, moving vertically and horizontally during a squat exercise. The barbell and weights move in tandem with the man's motion.

Background elements (walls, floor, gym equipment) are static; no shifting or environmental phenomena (fire, water, smoke, wind) observed.


A person in a red sweatshirt, blue jeans, black beanie, and black-and-white sneakers dances in a room with wooden walls. They start with hands on hips, step forward, jump, raise both arms, then widen their stance. Background includes hanging bags and cleaning supplies. The camera remains stationary.

A person in a red shirt and blue pants performs dynamic movements: arm swings, leg lifts, and body shifts, consistent with locomotion or exercise.

The wooden wall background with hanging tools (vacuum, buckets, etc.) remains stationary; no fluid motion (fire, water, smoke) or significant environmental drift is observed.


A green grid-patterned surface is shown. Light-skinned hands with a ring on one finger place a beige square paper onto the grid, adjusting and smoothing its position.

Hands manipulate a solid, discrete object (a piece of paper), exhibiting controlled physical interactions like placement and folding.

The green grid-patterned cutting mat background remains static throughout the video, with no shifting or fluid motion (e.g., fire, water, wind).


In an indoor gym, multiple people move around orange cones. A person in red runs from left to right across the court. A person in blue shirt picks up a ball and runs leftward, passing near the red-clad individual. The camera pans left, following the blue-shirted person toward the basketball hoop as other participants remain in the background.

A person in blue actively moves a ball across the court via locomotion and kicking; other individuals (red, green) are stationary or minimally moving. The ball exhibits discrete motion from explicit physical forces.

The background (walls, floor, basketball hoop) remains static with no shifting patterns or environmental motion (fire, water, smoke, wind). No ambient elements are present.


RAW CAPTION: Got it, let's break this down. First, the video shows a female athlete in a black sleeveless top and black shorts, number 10 on her outfit, performing a discus throw. She's on a concrete platform with a sandy field in the background.

Chronological order: She starts in a throwing stance, arms extended. Then she spins around, which is part of the discus throw technique. After spinning, she releases the discus, which goes into the air. Then she follows through, stops spinning, and steps back.

Other people: There's a man in a blue shirt and light shorts with a hat standing to her left (maybe a judge or coach), another person in a dark outfit further back, and a man sitting in a chair with a red and white flag to the right.

Background: Trees and a fence, but minimal.

Camera perspective: It's a fixed camera, probably side view, no movement mentioned.

Need to keep it concise. Let's structure:

A female athlete in black athletic wear throws a discus. She begins in a throwing stance, spins to generate momentum, releases the discus, and follows through. Observers stand nearby: one in blue shirt and light shorts to her left, others in the background. The camera captures the action from a fixed side angle with a clear view of the sandy field and trees.

Wait, check rules: focus on motion and behavior chronologically. So first, her stance, then spin, release, follow through. Mention appearance: black top, shorts, number 10 (but rule f says exclude named characters, but appearance like color, size. Wait, rule b says briefly describe appearance and number (color, size, orientation). So "female athlete in black sleeveless top and black shorts" is okay.

Spatial relationships: the observer in blue shirt is to her left, another person further back in the field.

Background minimal: mention if essential. The sandy field and trees are part of the event, so maybe just "sandy field with trees in background" but keep minimal.

Camera perspective: fixed side angle, no movement.

Let's draft:

A female athlete in black athletic wear performs a discus throw on a concrete platform. She starts in a throwing stance, spins clockwise, releases the discus into the air, then steps back and turns to face the field. Observers stand to her left (a man in a blue shirt and light shorts) and further back on the sandy field. The camera captures the sequence from a fixed side angle with minimal background details.

Check rules: no text recognition, named characters excluded. The number 10 was on her outfit, but since it's part of her appearance, but rule f says exclude named characters. Wait, "number 10" is a detail, but maybe it's okay as part of description. Wait, rule f: "Exclude text recognition, named characters, or stylistic analysis." So text on her clothes (number) is text recognition, so exclude. So don't mention number 10.

So revise: "A female athlete in black sleeveless top and black shorts performs a discus throw on a concrete platform. She starts in a throwing stance, spins clockwise, releases the discus into the air, then steps back and turns to face the field. Observers stand to her left (a man in a blue shirt and light shorts) and further back on the sandy field. The camera captures the sequence from a fixed side angle with minimal background details."

Check chronological order: stance, spin, release, follow through (step back, turn). Yes.

Appearance: black sleeveless top, black shorts. Color, size (she's female, athletic, so size is implied as athletic).

Spatial: observer to left, others further back.

Background: sandy field, trees, but minimal. "minimal background details" is okay.

Camera: fixed side angle, no movement mentioned (so "fixed side angle").

Is "sandy field with trees" needed? Maybe not essential, but the action is on the platform, so maybe just "sandy field" as part of the setting.

Let me check the example in the rules: rule e says "minimize background descriptions unless essential for understanding motion." Here, the motion is discus throw, so the field is where the discus lands, but maybe not essential. But in the video, the field is the area where the throw is directed, so maybe mention the sandy field as the area where the discus would land.

But rule e says minimal, so maybe not.

Wait, the original video has a sandy field in the background. The action is on the concrete platform (the throwing circle), so the sandy field is the landing area. But since the camera is fixed, the motion is the throw, so maybe just "a sandy field" as part of the setting.

Putting it

Discrete objects: (1) Female athlete (performing rotational discus throw: spinning, releasing discus, and recovering stance), (2) Discus (launched into air and moving through space). Static objects: officials, trees, fence, and ground.

The background (trees, fence, sand area, and officials) is static with no shifting or fluid motion. No fire, water, smoke, or wind effects are visible that would indicate ambient environmental motion. Background elements like trees and the fence show no displacement.


Four men perform music on a cobblestone street; leftmost (gray-haired, black outfit) plays violin, next (dark shirt) plays guitar, middle (brown hat, light pants) plays accordion, and rightmost (black tank top, cargo pants) holds paper. They play instruments, then the rightmost man steps forward and holds the paper. The camera pans left slightly to follow their movements.

Multiple solid objects (people) exhibit locomotion: musicians standing and playing instruments, a person holding papers walking, and a pedestrian passing through the frame.

Static background elements (building, signs, railings) show no uniform shifting or fluid environmental motion (no fire, water, smoke, or wind).


A woman in a white tank top and black pants holds a bottle while a child wearing large black headphones and a striped shirt stands in front of her. The child moves left, turns toward the woman, then steps closer to the camera as the woman steps back. The camera captures the scene with slight shake, following the subjects’ movements, with a brown couch visible in the background.

The child (wearing headphones) and adult are moving: the child steps forward/backward, turns, and interacts with the adult; the adult bends and handles a bottle. All motion is deliberate locomotion by solid bodies.

The background (brown leather couch, fireplace, framed pictures) shows no uniform shifting or fluid motion. Static elements remain fixed without environmental distortion (e.g., no fire, water, or smoke).


An athlete in a black outfit stands in a discus throwing circle within a green safety net, initially extending their arm forward with the discus. They begin a rotational motion, pivoting on one foot while swinging the discus in a circular path. The athlete completes the throw, releasing the discus and stepping out of the circle, with the discus traveling through the air. The camera remains stationary, positioned outside the net, capturing the athlete’s motion from a side perspective with the net’s mesh partially obscuring the view.

A person (athlete) performs rotational motion (spinning) and a thrown object (e.g., discus) exhibits ballistic flight. Both objects show discrete, physics-driven motion.

The netted enclosure and distant structures (e.g., spectators, ground) remain stationary, with no fluid motion (fire, water, smoke) or wind-driven displacement observed.


A person holds a vertically stacked, multicolored die tower (green, blue, yellow faces visible) with both hands; they rotate the tower slightly. Next, the person holds a black cylindrical cup, rotating it to display its interior and exterior. The camera maintains a close-up perspective on the hands and objects throughout, with minimal background detail.

The person is manipulating two discrete solid objects: a LEGO stack and a black cylindrical cup. The motion of these objects is due to hand movements (rotation and holding).

The background (wall and person's shirt) is static with no fluid or environmental motion (e.g., fire, water, wind).


A pair of adult hands manipulates thin metal tools, inserting them into the keyhole of a silver lock mounted on a stand. The hands repeatedly adjust the tools within the keyhole, then briefly remove and reinsert them. Several black-handled tools rest on the table to the right of the lock. The camera remains in a static, close-up position focused on the lock and hands throughout the sequence.

A person's hands are manipulating keys, tools, and the key-cutting machine. The hands and keys exhibit distinct motion due to explicit physical forces (e.g., grasping, inserting, and turning keys).

Stable background with no shifting elements or fluid/environmental motion (fire, water, wind) detected. The sign and table remain static throughout.


A large white truck with a long crane arm moves left across a dirt ground area, its crane arm extending as it travels. A worker wearing a red helmet is visible on the truck's flatbed, positioned near the crane. The truck progresses past a large metal structure in the background. The camera pans left, following the truck's movement with a slight shake.

The truck and crane arm move leftward across the frame due to locomotion; people on the truck are visible but not moving independently.

Background elements (buildings, terrain) show no uniform shifting or fluid motion; no fire, water, or wind dominates the scene.


Two men in white shirts work on a wooden foundation frame in a grassy backyard adjacent to a gray house. The first man starts bent over the frame, then stands and walks toward the house. The second man moves from the house’s window area to the frame. The camera maintains a static, wide-angle view throughout.

A single human subject is moving: bending, walking, and using tools within the foundation area.

The background elements (house, shed, grass) show no significant shifting or fluid/environmental motion (e.g., no fire, water, smoke, or wind-driven swaying).


A woman in a blue patterned top holds an orange crocheted item with white accents. Another individual with white hair approaches from the right, observing the object. The camera pans right to reveal additional seated individuals near the first woman. Background features a brick wall. Camera movement is slight pan right.

Two individuals are present: a person in a blue patterned shirt holding an orange object and another person with white hair. Both exhibit subtle movements (e.g., slight shifts in posture, hand gestures), consistent with human locomotion or interaction.

The background consists of a static brick wall with no visible fluid motion (fire, water, smoke) or wind effects. The brick wall remains uniformly positioned across frames, indicating no ambient environmental motion.


A person with short brown hair, wearing an in-ear device, smiles and speaks while raising their hand to adjust their hair; the scene transitions to a cyclist in a helmet and backpack riding a bicycle at a crosswalk with pedestrians nearby. The camera maintains a close-up focus on the first subject before cutting to a static medium shot of the street scene.

A cyclist is moving through the street, demonstrating locomotion via pedaling with distinct motion trajectory.

Background elements (building, traffic lights, street markings) are static with no uniform shifting; no fluid/environmental motion (fire, water, wind) detected.


A boy in a white shirt and blue shorts bends over a cardboard box against a blue wall, lifting and repositioning it on the wet ground while a person in a striped shirt and dark shorts stands behind him. The camera remains stationary with minimal shake.

A person (wearing white shirt and blue shorts) is moving a tire by pushing and placing it on the ground. A second person walks in the background but is not the primary focus.

The background (blue wall and concrete ground) is static with no shifting. No environmental fluids (fire, water, smoke, wind) are present.


RAW CAPTION: Got it, let's see. The video starts with a person standing on a basketball court. They're wearing a gray t-shirt with some text, brown shorts, and holding a basketball. Then they start skateboarding. The next part shows them riding the skateboard, moving across the court. The background has trees and a clear sky. I need to describe this chronologically.

First, the person is standing, then they skateboard. So the sequence is: standing with basketball, then skating. The appearance: gray shirt, brown shorts. Motion: starts standing, then skates forward, maybe doing some tricks? Wait, the video shows them in motion, bending, then standing up. So the action is starting to skateboard, moving, then maybe a trick, then stopping. Wait, the frames: first frame is standing holding ball, then frame 2 shows them on skateboard, moving, frame 3 is same action, frame 4, frame 5 they stop. So the main subject is the person. So the caption should go from the start: standing on the court with basketball, then starts skateboarding, moves across the court, and then stops. Also, the camera: first static, then maybe following the movement? The rules say to mention camera perspective and movement. Let's check the rules.

a) Chronological order: start, then skateboard, then stop. b) Appearance: gray shirt, brown shorts, holding basketball (initially), then on skateboard. c) Spatial: basketball court, background trees. d) Camera: first static shot, then maybe tracking the movement? The first frame is static, then the next frames show the person moving, so camera might be following. Wait, the problem says "conclude with the camera perspective and movement". So in the output, after the action, note the camera.

Let's structure it:

- Start: A person in a gray t-shirt and brown shorts stands on a basketball court holding a basketball.
- Then: they begin skateboarding, moving forward across the court, bending slightly while riding.
- Then: they stop, facing the camera again (maybe the last frame shows them standing).

Background is minimal, so mention the court and trees briefly.

Wait, the video has 5 frames. Frame 0: person standing holding ball. Frame 1: same as 0? Wait, no, the user provided 5 frames. The first frame is [0.0], then [1.4] shows skating. Wait, the timestamps: [0.0] is the first, then [1.4] is a different shot. Wait, the description says: first frame is person holding ball, then next is skating. So the sequence is: person stands, then skates, then maybe does a trick, then skates, then stops. Wait, the frames are:

<0.3 seconds> - person standing holding basketball on court.

<1.4 seconds> - person on skateboard, moving, bent over.

<2.5> - same action, moving forward.

<3.6> - same, moving.

<4.7> - person standing again, holding something (maybe the basketball? Wait, the description for [4.7] says same as initial, so standing with basketball.

Wait, the second frame (1.4s) shows the person on a skateboard, moving, so they start skateboarding, ride across the court, and then stop at the end. So the motion is: start standing, then skate (moving), then stop. So the chronological order is: standing with basketball, then begins skateboarding, moving across the court, then stops.

Now, the caption needs to be concise. Let's outline:

A person wearing a gray t-shirt and brown shorts stands on a basketball court holding a basketball. They begin skateboarding, moving forward across the court while bending slightly, then stop and face the camera. The background includes trees and a clear sky, and the camera follows the person's movement from a side perspective before returning to a static shot.

Wait, but need to keep it concise. Let's check the rules again. Exclude text recognition, so don't mention "BLACK ANTI" etc. Just mention the colors: gray shirt, brown shorts.

So:

A person in a gray t-shirt and brown shorts stands on a basketball court holding a basketball. They start skateboarding, moving forward across the court while bending, then stop. The background features trees and a clear sky. The camera follows the person’s motion from a side angle during skating before returning to a static shot.

Wait, but need to check chronological order, appearance, motion.

Let's make sure:

- Initial: standing on court, holding basketball (gray shirt, brown shorts)
- Then: skates forward, bending (motion: skateboarding, moving across)
- Then: stops, facing camera (so the last frame is standing again)

Yes

A person skateboarding, performing discrete locomotion (pushing off ground to move forward) with visible physics: skate wheels on pavement, body posture changes during motion, and foot movements.

Background elements (trees, basketball hoop, sky) are stationary with no uniform shifting or dominant fluid motion (wind is negligible and not dominant). No fire, water, smoke, or significant wind effects observed.


A person in a red and black striped shirt and blue jeans lies on a patterned rug, then sits up and shifts position. Nearby, another person in blue jeans and a gray top stands close to a small wooden table, remaining stationary. The person on the rug adjusts their posture while the standing individual stays in place. The camera captures the scene from a handheld, slightly shaky perspective with minimal movement.

Two solid objects (a child and an adult) move: the child repeatedly stands, falls, and interacts with the adult; the adult stands and holds an object while observing the child.

Background elements (sofas, coffee table, rugs) remain static with no uniform shifting. No fire, water, smoke, or wind motion observed.


A baby in a pink shirt with a floral design and gray pants sits on a bed, holding a yellow toy. The baby moves the toy toward a blue toy positioned in front, then turns to face the camera directly. The camera maintains a steady, close frontal perspective throughout the sequence.

The baby (solid object) is moving its arms and holding a yellow toy, with subtle torso shifts; no other solid objects exhibit meaningful motion.

Background elements (walls, lamp, furniture) show no uniform shifting or fluid motion; no fire, water, or smoke observed.


Two individuals are outdoors on a concrete surface. One person in a sleeveless top and dark shorts lies prone, performing sit-ups while another person in a white tank top and dark shorts crouches beside them, holding their legs. The sit-up performer lifts and lowers their torso repeatedly. The camera remains stationary with a slight shake.

One person performs sit-ups on the ground while the other kneels holding their feet; motion is confined to the human subjects' locomotion due to muscular exertion.

The background (building, ground, trees) shows no shifting or environmental motion (e.g., no fire, water, smoke, or significant wind effects; trees are static).


A woman with long, wavy brown hair wearing a blue top uses a curling iron on her hair, positioned in front of a pink wall with a laptop displaying a screen and a round mirror. A white fluffy dog moves into the frame, briefly obscuring her view, then steps back. She turns her head to face the camera directly. The camera remains stationary throughout.

The person is moving their arms (blow-drying hair), and the dog is moving its head/body through the frame; both are solid objects exhibiting locomotion and interaction with the environment.

Background elements (door, mirror, laptop) remain static with no uniform shifting. No fire, water, smoke, or wind present; ambient motion is negligible.


A child with light brown hair and a green patterned shirt sits as another person’s hands adjust their hair. The scene shifts to a girl with dark hair in a blue hoodie, who has her hair adjusted by a person behind her; she turns toward a window where another individual in a white sleeveless top stands. The girl looks out the window while someone adjusts her hair. The camera moves between close-ups and mid-shots, showing slight perspective shifts.

Discrete human subjects (child, adults) moving via physical interactions (touching hair, adjusting posture, entering frame).

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


A person's right hand, with visible skin tone and fingers, presses black and white keyboard keys in sequence on a dark gray keyboard, moving slightly across the keys. The hand remains centered on the keyboard with minimal background elements visible. The camera maintains a static close-up view focused on the hand and keyboard.

A human hand is actively pressing keys on a keyboard, exhibiting discrete motion through controlled finger movements due to explicit physical forces (muscle action).

The background (wooden floor and keyboard structure) shows no shifting, fluid motion, or environmental elements like fire/water/smoke. Background elements remain stationary throughout the clip.


Two individuals in swimwear underwater wear snorkel masks with bubbles ascending, positioned side by side: the left in light blue trunks, the right in black shorts with a white pattern. A third person in dark swimwear and fins is partially visible behind them. Fish swim around them in the clear blue water as the two front individuals remain mostly stationary, occasionally adjusting their masks. The camera maintains a steady frontal underwater perspective with slight movement, capturing the scene without significant spatial shifts.

Two people (in swimsuits) are moving slowly in the water, holding each other and using their limbs for propulsion. Fish are swimming around them.

The background (seabed) is static. The water shows minimal movement (bubbles from snorkels), but the dominant motion is the movement of the two people. Fish are swimming but are not the dominant motion.


A person in a red jacket and black pants walks toward a black bench on a green gym floor. They bend forward, placing hands on the bench while extending one leg behind them into a lunge position. A large blue exercise ball rests on the floor to the right of the bench. The background features red walls with hanging gym equipment, including dumbbells and straps. The camera remains stationary throughout the sequence.

A person in a red shirt and black pants performs a lunge exercise, moving their legs and torso.

Background elements (red walls, green floor, gym equipment) are static; no fluid or environmental motion detected.


RAW CAPTION: Got it, let's break this down. The video starts with a close-up of a person's face, specifically the eyebrow area. A hand holding a makeup brush is seen applying product. Then there's a close-up of the brush itself, showing its details. After that, the brush is used again on the eyebrow, maybe grooming or filling it in.

First, identify the main subjects: the person (face, eyebrow), the makeup brush, and the hand holding it. The sequence: initial close-up of face with brush application, then brush close-up, then brush back on the eyebrow.

Appearance: The brush has a black handle with silver, a logo, and a brown bristle tip. The person's eyebrow is being worked on.

Spatial relationships: The brush is in front of the eyebrow, held by a hand. The camera shifts focus between the face and the brush.

Camera movement: The video starts with a close-up of the face, then zooms in on the brush, then back to the face with the brush in action.

Background: Minimal, just blurred elements, not necessary to mention.

Now, structure the caption chronologically. Start with the first action: close-up of face with hand holding brush applying to eyebrow. Then close-up of brush. Then brush applied again. Conclude with camera perspective: close-ups, zooming in and out.

Check the rules: focus on motion, chronological, mention appearance (brush color, size), spatial (brush in front of eyebrow), conclude camera movement.

Let's draft:

A hand holding a black-handled makeup brush with silver ferrule and brown bristles applies product to a person's eyebrow in a close-up shot. The camera zooms in to show the brush details, then returns to the face as the brush continues grooming the eyebrow. The camera maintains tight close-ups throughout, shifting focus between the brush and the eyebrow application.

Wait, need to check if "grooming" is accurate. The brush is likely being used to shape or fill the eyebrow. The actions are: applying product (maybe with brush), then close-up of brush, then brushing again.

Also, mention the brush's appearance: "black handle, silver ferrule, brown bristle tip" – yes.

Number: one brush, one hand.

Chronological order:

1. Close-up of face with brush applying to eyebrow.

2. Close-up of brush alone.

3. Brush applied again on eyebrow.

Camera perspective: close-ups, shifting focus.

Let's make it concise.

"A hand holds a black-handled makeup brush with a silver ferrule and brown bristles, applying product to a person’s eyebrow in a close-up. The camera zooms in on the brush, showcasing its details, then returns to the face as the brush continues grooming the eyebrow. The camera maintains tight close-up shots with shifting focus between the brush and the eyebrow application."

Check if "grooming" is right. The brush is on the eyebrow, so maybe "grooming" is okay. Alternatively, "applying makeup to the eyebrow."

But the video shows the brush being used on the eyebrow, so "applying product to the eyebrow" is accurate.

Also, check if the brush is held in hand: "a hand holds..." yes, the first frame shows a hand.

Another point: the brush is shown in close-up, then the hand is seen applying it.

So the order:

- Start: close-up of face, hand with brush applying to eyebrow.

- Then: close-up of brush (showing details).

- Then: brush back on eyebrow.

So the caption should capture that sequence.

"Close-up shot shows a hand holding a black-handled makeup brush with a silver ferrule and brown bristles applying product to a person’s eyebrow. The camera zooms in on the brush, displaying its features, then shifts back to the face as the brush continues application on the eyebrow. The camera maintains tight close-ups throughout, moving focus between the brush and the eyebrow."

That's good. Check rule f: exclude text, which we did. Rule g: no reasoning.

Now, make sure it's concise. Let's trim.

"A hand holds a black-handled makeup brush with silver ferrule and brown bristles, applying product to a person’s eyebrow in a close-up. The camera zooms in to show the brush details, then returns to the face as the brush continues grooming the eyebrow. The camera maintains tight close-up shots with shifting focus between the brush and eyebrow application."

Wait, "grooming" might not be exact. The action is applying makeup, so "applying makeup to the eyebrow" is better.

Let's revise:

"A hand holds a black-handled makeup brush with a silver ferrule and brown bristles, applying makeup to a person’s eyebrow in a close-up. The camera zooms in on the brush, displaying its features, then shifts back to

The makeup brush is the primary moving object, being held and moved by a hand to apply makeup to the eyebrow. The eyebrow itself is being groomed, but the motion is controlled and discrete.

The background is static and blurred but shows no shifting or environmental elements (no fire, water, wind).


A hand adjusts a white document binding machine with a blue sheet inserted, then pulls the sheet through the machine's rollers, moving it forward into the binding mechanism. The hand manipulates the sheet and machine parts, with the camera maintaining a top-down perspective focused on the action. The background features a brown countertop.

A human hand (discrete solid object) moves to operate the document roller, demonstrating physical interaction with the machine.

Background elements (floor, document roller structure) show no uniform shifting or fluid motion; no fire, water, or smoke present.


A man in a maroon shirt and green pants performs breakdancing moves on a wooden mat, spinning on his hands, executing a backflip, and landing on his back while spectators observe from the surrounding area; the camera remains steady, capturing the action from a frontal perspective.

The breakdancer (solid, distinct object) executes acrobatic moves including spins, freezes, and body rolls; secondary motion includes minor shifts by onlookers but is not dominant.

No shifting backgrounds or fluid/environmental motion (fire, water, wind) observed; static elements like trees, stage structure, and spectators remain stable with no uniform displacement.


A man in a dark green jacket, black pants, and white shoes wearing a fencing mask and a child in a white jacket with a red emblem, black shorts, and white shoes engage in fencing. The man lunges forward, then steps left as the child steps right; the child advances toward the man, who steps back. Other fencers are visible in the background. The camera remains stationary with a slight shake.

Multiple discrete solid objects (people) moving: two foreground subjects (adult and child) performing martial arts movements (punches, steps), with additional background pairs similarly engaged. All motion is intentional locomotion with clear bounding boxes.

Background walls, windows, and floor tiles remain static with no uniform shifting. No fire, water, smoke, or wind effects are visible; the environment is dry and controlled.


A pair of hands holds a light brown wooden object vertically while using a metal chisel with a wooden handle to carve its surface; the right hand maneuvers the chisel along the wood, creating fine shavings, while the left hand steadies the object, which is positioned in front of scattered wood shavings and workshop tools (including pliers and a fork) on a worn wooden surface. The camera maintains a static top-down perspective throughout.

Hands manipulating a wooden object and a carving tool, exhibiting controlled motion from physical carving actions.

Background elements (tools, debris, floor) appear static with no uniform shifting or fluid motion; no fire, water, smoke, or wind detected.


A shirtless young boy in white underwear stands in a dimly lit bedroom, moves his right hand toward his waist, turns left, and bends forward; the camera remains static with slight shake, capturing him near a bed with blue patterned sheets and scattered items.

A shirtless boy is moving: bending, adjusting his diaper, and manipulating objects (e.g., a small item in his hands). Solid, distinct motion from physical actions.

No shifting background elements (walls, bed, furniture remain stationary) or fluid/environmental motion (fire, water, smoke) detected.


A child in a blue shirt rapidly stacks cups on a table while a man in black holds a digital timer displaying changing numbers. The child moves between positions near the cups, completing the stacking task, while the man adjusts the timer. The scene occurs in a well-lit indoor space with background banners and onlookers, observed from a fixed frontal camera angle.

A person in a blue shirt stacks cups (discrete object motion), while another person interacts with the cups; both movements are driven by physical actions (stacking, handling).

Background elements (signs, stationary people) show no uniform shifting; no fire, water, or smoke present. Ambient motion is negligible.


RAW CAPTION: Got it, let's break this down. The video is black and white, showing a bowling alley. First, the opening frame has a person standing near the lanes, facing away. Then, the person walks towards a device (probably a scoring machine or something) and interacts with it. Then, the scene shifts to the person standing near a table where others are seated. Wait, need to follow chronological order.

Frame 0: Person standing in front of bowling lanes, back to camera.

Frame 1: Person moves towards a chair-like object? Wait, the next frames: frame 1.3 shows a person walking, then frame 2.5 shows the person approaching a machine (maybe a ball return or scoring system). Then frame 3.5: the person is standing over the machine, possibly adjusting it. Then frame 4.7: the scene changes to a group of people, one of whom is standing near a table with others seated.

So main subjects: one person (male, dark shirt, dark pants, white shoes? Maybe, but black and white so colors are hard). The person walks from the lanes towards a mechanical device, interacts with it, then moves to a seating area where others are.

Background: bowling lanes (multiple, with pins at the end in the first frame), then a room with a table and people.

Camera: starts with a static shot of lanes, then follows the person's movement, then cuts to the seating area.

Need to be concise, chronological. Mention appearance (male, dark attire), motion (walking towards, interacting with device, then to table), spatial relationships (in front of lanes, near device, then near table with others).

Avoid text, names. Background minimal.

Let's structure:

The video opens with a man standing in front of bowling lanes, facing away. He walks toward a circular device on the floor, bends over, and interacts with it. He then moves to a seating area where several people are gathered around a table, standing near the seated group. The camera remains static throughout, with a brief shift in perspective to follow the man’s movement between locations.

Wait, check rules: focus on motion and behavior, chronological. Mention appearance (male, dark shirt/pants), number (one person), spatial relationships (in front of lanes, near device, then near table). Background minimal.

Also, check the frames: first frame is the man at the lanes, then he moves to the device (which is in front of him), then to the table. So step by step:

- Initially, a man stands facing away from the camera in front of multiple bowling lanes.
- He walks toward a circular mechanical device on the floor, bends over, and adjusts it with his hands.
- The scene transitions to a room where the man stands near a table with several seated individuals.

Camera: starts with a view of lanes, follows the man's movement (so slight pan or follow), then cuts to the table scene.

Wait, the problem says "Conclude with the camera perspective and movement". So need to mention camera aspects.

Let me draft:

A man in a dark shirt and dark pants walks from the bowling lanes toward a circular device on the floor. He bends over, adjusts the device with his hands, then moves to stand near a table where several seated individuals are gathered. The camera remains static during the lane sequence, follows the man’s movement toward the device, and cuts to a static shot of the table scene.

But check if the man's appearance is needed: "male in dark shirt and dark pants" (since black and white, color isn't visible, but appearance like dark attire).

Also, the second part: the man interacts with the device (maybe the ball return or scoring machine), then the scene shifts to him near the table. So chronological order: 1. standing at lanes, 2. walking to device, 3. interacting, 4. moving to table.

Let me check the timestamps:

[0.0] - man standing at lanes, back to camera.

[1.4] - man is now near a chair (maybe the device), moving.

[2.5] - man is closer to device, bending.

[3.6] - man is over the device, adjusting.

[4.7] - scene changes to man near table with others.

So:

The video begins with a man standing facing away from the camera at the end of bowling lanes. He walks toward a circular mechanical device on the floor, bends over, and manipulates it with his hands. After interacting with the device, he moves to stand near a table where several seated individuals are gathered. The camera starts with a static view of the lanes, tracks the man's movement toward the device, and cuts to a static shot of the table scene.

Yes, that seems to fit. Check rules:

a) Motion: standing, walking, bending

The bowler is walking, turning, and interacting with the ball return; stationary spectators are visible.

No shifting background or fluid/environmental motion; lanes and walls are static.


RAW CAPTION: Got it, let's break this down. The video shows a large crowd around a central area where people are moving. First, I need to describe the main subjects in chronological order. The main subjects here are the people in the center—there's a group of them, maybe dancers or performers. They're moving around, probably in a dance or formation. The crowd is surrounding them, taking photos or videos.

Looking at the rules: focus on motion and behavior. So start with the central group. How many? The video shows a group, maybe 10-20 people? They're moving in a circular or choreographed way. Then the crowd is stationary, some holding phones up. Spatial relationship: central group is surrounded by the crowd. Camera perspective—seems like a wide shot, maybe panning slightly? Wait, the frames show the camera moving a bit, maybe panning left? Let's check the video description. The video starts with a wide shot of the crowd around the central area. The people in the center are moving, perhaps dancing. The crowd is dense, with many people holding up phones. The camera might be static or slightly moving. Wait, the problem says to describe camera perspective and movement.

Also, background is minimal—just the crowd. So don't mention the venue details, just the crowd. The caption needs to be concise, chronological. Let's structure it:

First, the main subjects (people in center) start moving in a formation. Then the crowd is around them. Then, as time goes, they keep moving. Camera perspective: probably a high-angle shot (since it's looking down on the crowd), maybe panning slightly.

Wait, the rules say "conclude with the camera perspective and movement". So in the end, state how the camera is positioned. Let's see: the video starts with a view of the crowd, then the camera might move or stay. The given frames show the camera panning from left to right? Wait, the first frame is a wide shot, then as it progresses, maybe the camera shifts. But the problem says to describe in chronological order. So the main action is the central group moving around the center, with the crowd surrounding them. The camera is capturing from an elevated angle, panning slightly to follow the movement.

Now, appearance: the people in the center are a group, maybe wearing dark or varied clothes? But the rules say mention appearance briefly if relevant. Maybe "a group of people, some in dark attire" but maybe keep it minimal. The rules say "briefly describe their appearance and number (color, size, orientation)". So "a group of approximately 15 people in casual attire" but maybe not exact number. Alternatively, "a group of performers in varied clothing" but since it's a public event, maybe they're in similar outfits. Wait, the video is a crowded event, like a festival or concert. The central group is moving in a coordinated way.

So step by step:

1. Chronological order: The video shows a large crowd surrounding a central area where a group of people (the main subjects) are moving in a choreographed manner. They start moving in a circular formation, advancing and retreating in unison. The crowd remains stationary, many raising smartphones to record the event.

2. Appearance and number: A group of approximately 15-20 individuals, wearing casual or performance-oriented clothing, moving in synchronized steps.

3. Spatial relationships: The central group is positioned in the middle of a large crowd, which surrounds them on all sides.

4. Camera perspective: The camera is positioned at a high angle, providing an overview of the scene, and moves slightly to the left throughout the sequence.

Now, make it concise. Let's put it all together:

A group of around 15 people in casual clothing moves in a circular, synchronized formation at the center of a large crowd, advancing and retreating in unison while the audience surrounds them, many holding up smartphones. The camera captures this from a high angle, slightly panning left to follow the central group's motion.

Wait, check rules: "conclude with the camera perspective and movement". So maybe:

The central group of 15-20 people in casual attire performs a choreographed dance, moving in synchronized circles while the surrounding crowd films with smartphones. The camera maintains a high-angle perspective, slowly panning left to track the movement.

But need to check if "high-angle" is correct. The description says "high angle" if it's from above. The video is a large crowd in an arena, so yes, high angle.

Let me check the rules again: "conclude with the camera perspective and movement (e.g., top-down, pan left, slight shake)". So "top-down" might be more specific. Wait, the first frame is a wide shot, possibly from the top.

Discrete objects: People on the stage (dancers/performers) are moving. They are engaged in coordinated locomotion (dancing). The crowd also has minor movements, but these are secondary.

The background is composed of a dense crowd which is not static, but there is no visible fire, water, smoke, or wind. The arena structure (walls, etc.) is not visible, so background shifting is not observable. However, the crowd movement is random and not fluid.


A person wearing a yellow shirt slowly inserts a white rectangular object into a slot on a machine with a digital display and control panels. The object is moved steadily into the slot, with the person’s arm visible throughout the action. The machine rests on a table in a dimly lit space with cardboard boxes in the background. The camera remains stationary, providing a close-up view of the machine and the insertion process.

A person's hands are actively pouring contents from a container into a machine, with discrete motion of the container and hands during the pouring action.

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


A person in dark athletic wear performs weighted sit-ups on a dark mat in a room with white walls and wooden panels. Starting in a seated position with legs bent and hands holding a weight above their head, they lower their upper body toward the floor, then return to the starting position repeatedly. The camera remains stationary, capturing the full-body motion from a frontal perspective.

Discrete solid objects: The person (performing a seated dumbbell exercise) and the dumbbell. The person moves by contracting muscles to lift and lower the dumbbell, exhibiting clear locomotion and force application.

Background (white walls, floor, shutters) is static with no shifting or environmental fluid motion (e.g., no fire, water, smoke, or wind). Static elements remain fixed throughout the clip.


A group of approximately seven people in casual attire (jeans, jackets) sit on a grassy area covered with blankets. They raise their hands in a clapping motion before lowering them to their laps. The camera pans across the group with a slight shake, capturing their seated arrangement from a ground-level perspective.

People in the scene are actively moving their hands in coordinated gestures (e.g., raising arms, clapping), representing discrete solid objects undergoing explicit physical locomotion and interaction.

The background consists of grass, blankets, and distant trees; no shifting uniform motion or fluid/environmental phenomena (fire, water, wind) are observed.


A person in a red shirt and orange pants throws a white frisbee across a grassy backyard, with a soccer goal and wooden fence in the background; the camera pans slightly to follow the frisbee's trajectory as it flies toward the goal.

The person in red clothing is moving (running and kicking) on the grass.

The background consists of houses, a fence, and trees. There is no dominant fluid motion (fire, water, smoke) or wind that shifts the scene.


A muscular man in a black sleeveless shirt and black-and-white cap lifts a barbell with weights, lowers it, and positions it on a weight rack in a gym; other individuals are visible working out in the background. The camera remains stationary, capturing the man's actions from a frontal perspective.

The man (subject) is performing a barbell lift (deadlift), lifting and lowering the barbell. This motion is due to his muscular effort (locomotion).

The gym background is static (no shifting of walls, floor, or fixed equipment). There is no fire, water, smoke, or wind. Minor background motion is due to people walking, but this is not dominant and is part of discrete object physics.


A child in light-colored clothing jumps above a picnic table under a park pavilion, lands on the ground, and walks toward the camera, passing beneath the shelter. The camera remains stationary throughout.

A person (wearing white shirt and light pants) jumps over a picnic table and then walks toward the camera.

The background (trees, building, grass) is static with no significant environmental fluid motion (fire, water, smoke, or wind).


RAW CAPTION: Got it, let's break this down. The video shows a young child in a gym setting. First, the child is standing near a black Everlast punching bag. The child is wearing a yellow shirt, dark shorts, and black shoes. Then, the child moves towards the punching bag, kicks it, and the bag swings. The camera is overhead, so top-down view. The background has gym equipment like weights and other machines, but we don't need to describe too much. Need to focus on the motion chronologically: child stands, moves, kicks the bag, and the bag moves. Spatial relationships: child is in front of the punching bag initially, then interacts with it. Camera is top-down, maybe slight movement? Let's check the frames: the video starts with the child near the bag, then moves, kicks, bag swings. So the caption should be chronological: child in yellow shirt and dark shorts stands near punching bag, moves towards it, kicks it, causing the bag to swing. Camera is top-down. Background is gym equipment, but minimal. So structure: main subject (child), actions in order, appearance, spatial, camera. Let's draft:

A small child in a yellow shirt, dark shorts, and black shoes stands near a black punching bag in a gym. The child moves forward, kicks the punching bag, causing it to swing. The camera captures the scene from a top-down perspective with slight movement.

Wait, check rules: "Focus primarily on the motion and behavior of main subjects (people/animals/objects) in chronological order." So the child's actions: standing, moving, kicking. Also, mention appearance (color, size). The child is small, so "small child". The punching bag is black. The gym background is there but minimal. Camera is top-down. Let's make sure to exclude text recognition (Everlast is text, so exclude). So the caption should not mention Everlast, just the bag's color.

Wait, the rules say "Exclude text recognition, named characters, or stylistic analysis." So the punching bag is black, but don't say "Everlast" because that's text. So describe it as "a black punching bag".

So the sequence:

At the start, the child is near the black punching bag. Then the child moves (steps towards it), then kicks it. The bag swings.

Chronological: The small child, dressed in a yellow shirt, dark shorts, and black shoes, stands beside a black punching bag in a gym. The child takes a step forward, then kicks the punching bag, which swings to the side. The camera remains stationary in a top-down view with minimal movement.

Wait, the camera movement: "slight shake"? In the video, is the camera moving? The frames show the child moving, so maybe the camera is static top-down. Let's see: the first frame is top-down, then the next, etc. So camera perspective is top-down, and movement is minimal (maybe slight shake as per the video description? The problem says "camera perspective and movement (e.g., top-down, pan left, slight shake)."

In the video, the camera seems to be a fixed top-down view, maybe with a slight shake, but maybe it's just a fixed top-down. Let's check the example: the user's example output might not have movement. But the rules say to conclude with camera perspective and movement. So "top-down perspective, no noticeable movement" or "top-down with slight shake". Since the video is a bit shaky, perhaps "slight shake".

Putting it all together:

A small child in a yellow shirt, dark shorts, and black shoes stands near a black punching bag in a gym. The child steps forward, kicks the bag, causing it to swing. The camera captures the scene from a top-down perspective with slight shake.

Check rules:

a) Motion chronological: stands, steps, kicks, bag swings.

b) Appearance: yellow shirt, dark shorts, black shoes, small child.

c) Spatial: child is near the bag, then moves towards it.

d) Camera: top-down, slight shake.

e) Background minimal: gym equipment is present but not detailed.

f) Exclude text, names, etc. (Everlast is excluded).

That seems to fit. Let's verify:

"small child" - size.

"yellow shirt, dark shorts, black shoes" - appearance.

"stands near a black punching bag" - spatial.

"steps forward, kicks the bag, causing it to swing" - motion chronological.

"camera captures from top-down perspective with slight shake" - camera.

Yes, that should be it.
</think>

<caption_output>A small child in a yellow shirt, dark shorts, and black shoes stands beside a black punching bag in a gym. The child steps forward, kicks the bag, and the bag swings to the side. The

A child (discrete solid object) moves toward and interacts with a punching bag, causing it to sway; both exhibit motion due to locomotion and physical impact.

The gym background (floor, equipment, punching bag) shows no uniform shifting or fluid motion; it remains static relative to the scene, with no signs of fire, water, or wind.


A person wearing a dark hooded coat walks away from the camera, moving in front of a building and beside a parked car. The individual’s back is visible as they proceed at a steady pace, with the camera remaining stationary and exhibiting slight movement.

A person is moving (walking) towards a bus, displaying discrete locomotion without interaction with other objects.

Static background elements (bus, building, car) show no uniform shifting or fluid motion. No fire, water, smoke, or wind detected.


A large crowd of formally dressed people, including men in dark suits and women in light and dark dresses, dance energetically in a circular formation. A central woman in a light-colored dress stands prominently amid the group, swaying and moving rhythmically as others surround her, stepping forward and backward. The crowd's motion creates dynamic shifts in positioning, with individuals occasionally moving closer to the center or stepping back. The camera pans slightly left while maintaining a medium shot, exhibiting minor shake as it tracks the dancers' fluid movements. Background details remain indistinct, focusing solely on the choreographed motion and spatial interaction within the group.

The main discrete objects are the dancing couple in the center and surrounding crowd members. The couple exhibits coordinated locomotion (swaying, stepping) due to physical forces (muscle movement), while the crowd shows random positional shifts as individuals move within the space.

The background consists of a dense crowd of people without visible static elements (e.g., walls, floor patterns). There are no fluids (fire, water, smoke) or wind-driven motion; the bright flashes are discrete light artifacts, not continuous environmental phenomena.


The video opens with a close-up of a blueberry bush laden with dark purple and light blue berries against green grass. A hand enters from the left, plucks a blueberry from the bush, and withdraws. The camera remains mostly static with minimal adjustment to track the hand’s movement.

A hand is the discrete solid object moving to interact with berries on a tree branch, demonstrating physical manipulation (picking berries) with visible force application.

The background (grass and foliage) shows minimal motion, likely caused by gentle wind swaying leaves, but no fluid/gaseous motion (e.g., fire, water, smoke) dominates. Background elements remain relatively stable without uniform shifting.


A bald man in a black sleeveless shirt stands in a gym, gripping a metal pull device with both hands. He repeatedly pulls the device upward toward his chest, then extends his arms to lower it, continuing the motion. Gym equipment is visible in the background. The camera remains static.

The person and the scissors they are holding are moving. The motion is deliberate and tracked by the person's arm movements.

Background is static (gym equipment, walls, window). No ambient environmental motion (fire, water, smoke, wind) detected.


Two individuals are in a dimly lit room with a window and bed. The person in a light shirt and dark pants stands near the window, then turns to face the other individual, raising their arms. The second person, wearing a dark hoodie, stands to the right of the first, moving their hands in a gesture. The camera remains stationary throughout the sequence.

Two people: one in light shirt (left) and one in dark shirt (right). The person in light shirt moves towards the window and adjusts posture; the person in dark shirt moves around, bending and gesturing.

Background elements (walls, window) are static; no fluid motion (fire, water, smoke, wind) observed.


RAW CAPTION: Got it, let's tackle this. First, I need to watch the video description. The video starts with a classroom scene. There's a person in a black shirt and jeans. At first, they're upside down, doing a cartwheel or flip maybe. Then they land on the floor, get up, and move around. Let's check the frames:

Frame 0: Person is upside down, probably mid-movement. Then frame 1-2: They land, stand up. Frame 2: They pick up something from a table? Frame 3: They walk towards the whiteboard, holding a whiteboard or paper. Frame 4: They're near the whiteboard, moving. Frame 5: They walk towards the window area.

Main subject is one person. Appearance: black shirt, jeans. Motion: starts upside down (flip), lands, stands, walks around the room. Background: classroom with whiteboard, bulletin boards, tables. Camera: probably fixed, but maybe a slight shake? Wait, the rules say exclude text recognition, so no need to mention text on whiteboard.

Chronological order: Person begins upside down in the room, completes a flip to the floor, stands up, picks up an object from a table, walks across the room towards the whiteboard, then moves to the window area.

Spatial relationships: Initially, person is near a table (wooden table with items), then moves around the room.

Camera perspective: Maybe fixed, but the video might have some shake. The instructions say to mention camera perspective and movement. The original description might have a slight shake? The problem says "slight shake" in examples. Let's see. The video's description is from 0 to 5 seconds, the camera doesn't move much, but maybe it's a slight shake.

Putting it all together:

A person wearing a black shirt and blue jeans performs a flip on the floor in a classroom, lands upright, picks up a white object from a table, and walks across the room towards a whiteboard and window, with the camera remaining mostly stationary but exhibiting slight movement.

Wait, check rules. Exclude text recognition, so don't mention "whiteboard" as text, but the whiteboard is part of the background. Wait, the rule says "background descriptions minimal unless essential for understanding motion." So classroom is essential, so mention room elements like whiteboard.

Wait, the main subject's motion: starts upside down (flip), lands, stands, walks. The object they pick up: white paper or board.

Let me structure:

In a classroom, a person in a black shirt and jeans executes a flip onto the floor, stands, and picks up a white rectangular object from a table. They then walk across the room, passing by a whiteboard and a table with various items, while the camera remains relatively static with minor movement.

Wait, check chronology: first flip (start of video), then land, pick up object, walk.

Wait, the frames:

0: upside down (flip start)

1: after flip, landing

2: standing, holding white object (from table)

3: walking towards whiteboard area

4: moving around

5: near window

So the sequence is: flips onto floor, stands, picks up white object from table, walks through the room, ending near the window.

Make sure to mention spatial: person starts in the center, flips to floor, then moves.

Also, the background has a whiteboard, bulletin boards, tables. But minimize background. So "in a classroom with a whiteboard and tables" might be too much. Wait, rule e: background minimal unless essential. So essential for motion: the room layout (like tables, whiteboard) helps understand where they move. So maybe "in a classroom containing a whiteboard and tables".

But the caption should be concise.

Let me draft:

A person in a black shirt and jeans flips onto the floor in a classroom, stands up, picks up a white object from a table, and walks across the room toward the whiteboard and window. The camera remains mostly stationary with slight movement.

Check rules:

a) motion: flip, stand, pick up, walk. Chronological.

b) appearance: black shirt, jeans. Number: one.

c) spatial: from table to whiteboard/window.

d) camera: stationary with slight movement.

e) background minimal: classroom with whiteboard and tables (essential for motion).

f) exclude text, named characters, etc.

g) internal thought, but output only caption.

Yes. Let's check the output format.

Final caption:

<caption_output>A person in a black shirt and jeans flips onto the floor in a classroom, stands up, picks up a white object from a table, and walks across the room toward the whiteboard and window. The camera remains mostly stationary with slight movement

A person (wearing dark clothing) performs discrete, solid-object physics: an acrobatic jump (backflip) and subsequent walking motion while moving a cardboard box across the room. The person and box are tracked as distinct, rigid objects with clear physical interactions.

Background elements (walls, whiteboard, posters, furniture) show no uniform shifting or environmental fluid motion (no fire, water, smoke, or wind). The room remains static throughout the sequence.


A person with red hair, dressed in dark clothing, performs a rhythmic gymnastics routine with two batons in an indoor gym. They swing the batons in wide arcs, twirl them overhead, and move dynamically across the blue floor, occasionally lowering the batons toward their body. The green bleachers and basketball hoop are visible in the background. The camera follows the performer’s movements with slight adjustments to maintain focus.

A person in black attire performs dynamic movements with a long object (likely a baton), exhibiting controlled body rotation and arm extension.

Green bleachers and walls remain static; no fire, water, smoke, or wind motion observed.


A person in a red shirt and dark pants stands on a stage platform. Another individual in a red shirt and beige pants leaps onto their back, causing both to fall together onto a blue mat below. The falling figures tumble forward, with the second person landing face-first as the first person rolls onto their side. The camera remains mostly static with slight movement, capturing the action from a frontal perspective.

Discrete objects include a person in red (initiating motion) and a person in white (being thrown/falling); their motion is driven by physical interactions (pushing, falling) and collisions with the platform/floor.

Background elements (e.g., "Extreme" banner, structural supports) show minimal uniform shift; fire is present as a secondary visual element but not dominant in motion dynamics.


A small baby in a light blue and beige checkered high chair, wearing a white shirt with blue trim, eats from a tray holding a plate of cake and fruit. The baby repeatedly brings hands to mouth and moves them away. Camera remains stationary, facing the baby frontally.

Baby in high chair exhibits hand and mouth movements consistent with eating (discrete solid object locomotion).

Background elements (wall, high chair, furniture) show no uniform shifting or fluid motion. No fire, water, smoke, or wind effects observed.


A hand manipulates a thick black cable, twisting and bending it near a wooden chair, moving the cable to loop and adjust its position. The camera remains in a close-up perspective with slight movement, focusing on the hand and cable while the background includes a wooden chair and indistinct interior elements.

A hand is moving a black cable, gripping and twisting it. The cable is being manipulated by the hand.

The background (wooden chair and room) shows no uniform shifting, and there is no fire, water, or smoke. Thus, no ambient environmental motion.


A hand enters the frame, positioned over a black mechanical component with a rectangular opening, then withdraws to reveal the opening. The hand returns, adjusts an internal element within the component, and extends a thumb to give a thumbs-up gesture before moving out of the frame. The camera maintains a close-up perspective, fixed on the component and hand interaction against a concrete floor background.

A hand interacts with a black mechanical object (likely a firearm or tool), performing discrete movements: pressing against the object and giving a thumbs-up gesture.

Background elements (floor, structural features) show no uniform shifting or fluid motion (fire/water/smoke). No environmental fluid dynamics present.


A white stovetop holds a black pan of green coffee beans, a black and glass coffee grinder, and a glass filter with a white paper cone. The camera zooms to a close-up of the beans, where a wooden spatula with a handle hole stirs them in a circular motion. The camera perspective transitions from a top-down view of the stovetop to a close-up focusing on the stirring action.

A wooden tool (with a rectangular slot) moves through coffee beans, causing them to shift. This is a solid, distinct object interacting with the beans via physical force (stirring).

Initial frames show static background elements (stove top, countertop) with no shifting. Camera zooms in on coffee beans, which is a camera-induced motion, but the primary action focuses on object movement.


A top-down view shows a person's hands painting on a white canvas. The left hand holds a brush with yellow paint, while the right hand applies white paint to a shaded area on the canvas. The right hand then dips a different brush into green paint from a palette, moving toward the canvas to add color. The workspace includes a palette with mixed paints, a container of water, and brushes arranged in the background. The camera remains stationary, capturing the hands' precise movements as they work on the artwork.

The person's hands and painting brushes are moving as they apply paint to the canvas.

Background elements (brush case, palette, cup) are stationary. No fluid motion (fire, water, smoke) or wind is present.


A close-up of a car's silver alloy wheel on a paved street. A hand holds a green spray can with a white nozzle, pressing it toward the wheel. The scene shifts to a person in a light blue shirt and black gloves crouching beside the car, spraying near the wheel while the spray can rests on the ground.

A hand holding a spray can moves toward and interacts with the car wheel; a person bends near the tire, both representing discrete solid objects in motion due to explicit human action.

Background elements (pavement, buildings, trees) show no uniform shifting or fluid motion (fire, water, smoke, wind); scene remains static with no environmental fluid dynamics.


A right hand with numbered fingers (1-5) moves to press a key on a piano keyboard. The scene transitions to a left hand with numbered fingers moving to press keys on the same keyboard. The camera remains stationary, showing the hands and keyboard from a top-down perspective.

The right hand and left hand are moving to press keys on the keyboard. The hand is a discrete, solid object with motion due to physical forces (fingers pressing keys).

The background is a static black screen with a keyboard. No shifting background or fluid motion (fire, water, wind) observed.


A shirtless child in yellow patterned shorts stands at a kitchen counter, lifting a large orange bowl and tilting it to pour contents into a lower white bowl. The child maneuvers the bowl above the counter, adjusting its position as other items—including a metal sieve, eggs, and bottles—remain on the speckled countertop. The camera maintains a steady position with a slight shake, capturing the scene from a fixed angle.

A person (shirtless, wearing yellow shorts) moves discrete objects: stirring contents of a bowl, lifting/positioning a larger bowl, and interacting with a mixing bowl.

Background elements (kitchen counter, cabinets, framed picture) are static; no fluid/environmental motion (fire, water, smoke) dominates the scene.


A man in a white shirt and red pants performs a barbell lift in a gym, raising the barbell from waist height above his head and lowering it back down. The camera remains stationary, capturing him from the front with gym equipment visible in the background.

A person in red pants and white shirt performs discrete lat pulldown exercise, moving the barbell up/down with controlled motion.

Static gym background (machines, walls, TVs) shows no shifting or environmental fluid motion (fire, water, wind).


A person in a plaid shirt and dark pants, carrying a black bag, walks along the brick wall of a school building, stops to raise their arm as if taking a photo, then steps away from the wall. The camera remains stationary with a slight pan following the person’s movement.

An adult and a child are moving as a pair, walking towards the building entrance.

No shifting background elements or fluid/environmental motion detected (e.g., no fire, water, smoke).


A man in a red shirt and a woman in a patterned dress stand near a rectangular birthday cake with white frosting and fruit toppings. The man steps closer to the cake, leaning forward as he adjusts his position, while the woman stands beside him. They both focus on the cake as the man reaches toward its surface. Several children wearing colorful party hats gather around the cake, with some positioned in front and others to the sides. The background includes minimal decorative elements, and the camera remains stationary in a medium shot throughout.

Person in red shirt cutting cake with hand motion; children shifting positions slightly; no significant object collisions or locomotion beyond human interaction.

Static background elements (walls, door, decorations) show no uniform shifting. No fire, water, smoke, or wind motion observed.


Hands hold a pen and write on a white notebook resting on a light pad; one hand briefly adjusts the notebook’s position. The notebook lies flat on the surface, surrounded by art supplies, with the camera maintaining a steady top-down perspective.

Discrete solid objects: hands manipulating items on the table (e.g., adjusting a glowing object, possibly a UV lamp or light source). Motion is driven by explicit physical actions (manual manipulation).

Background elements (shelves, wall, objects on table) remain static across frames; no fluid motion (fire, water, smoke, wind) detected.


Two individuals, one in a dark shirt and the other in a brown shirt, engage in a close embrace. The dark-shirted person holds the brown-shirted individual, who faces away from the camera. The scene occurs in a room with blue walls and visible microphone equipment, captured from a static, frontal perspective with minimal movement.

Two people are moving in close proximity, exhibiting physical interaction (hugging or embracing), with one individual holding a camera.

The blue wall and hanging objects remain static across frames, with no visible fluid motion (fire, water, smoke) or environmental elements dominating the scene.


RAW CAPTION: Got it, let's tackle this. First, the video starts with a black screen, then shows a title "Cutter (cut fastball)" but according to the rules, I should exclude text recognition. So skip that. Next, the scene shifts to a baseball field with a net. There's a person (pitcher) in the distance. Wait, the video shows a person throwing a ball towards the net. The first frame after the title is a view through a net, so the camera is behind the net. The pitcher is in the middle ground, throwing a ball. Then the ball comes through the net. Let's check the timeline.

Frame 0: black screen, text is excluded. Frame 1: black screen. Frame 2: net view, pitcher (maybe) in field, but the text is there but we don't mention it. Wait, the user says exclude text recognition, so ignore the text. So the video starts with a black screen, then cuts to a view through a net. The net is in the foreground, so the camera is positioned behind the net looking out. There's a person (likely a pitcher) standing on the grassy field, and they throw a ball towards the net. The ball moves through the net, and the person remains in the background. Let's describe chronologically.

First, the video begins with a black screen. Then, it transitions to a view through a blue net, showing a grassy field with a person in the distance. The person appears to be throwing a ball towards the net. The ball moves forward through the net, and the person stays in the background. The camera remains stationary, looking through the net, with the field and trees in the background. Now, check the rules: focus on motion and behavior of main subjects. Main subjects are the person (pitcher) and the ball. The person is throwing the ball. Appearance: the person is in the distance, probably wearing athletic clothing, but size and color not specified. Spatial relationship: person is behind the net (since the net is in front of the camera), so the person is in front of the camera's view through the net. Wait, the camera is positioned such that the net is in the foreground, so the field is behind the net. The person is on the field, so they are in front of the net. So when the ball is thrown, it comes through the net.

Let's structure it:

The video starts with a black screen, then cuts to a view through a blue net. A person stands on a grassy field in the distance, throwing a ball toward the net. The ball moves forward through the net, passing through its mesh. The person remains stationary in the background while the ball travels. The camera maintains a fixed position, capturing the scene through the net with minimal movement, focused on the ball's trajectory.

Check the rules: chronological order. Main subjects: person and ball. Their motion: person throws, ball moves. Appearance: person is in distance, size not specified, color irrelevant. Spatial: person is in front of the net (since the net is the foreground, person is behind the net? Wait, no: the camera is behind the net, looking towards the field. So the field is in front of the net, so the person is on the field, which is in front of the net. So the person is in front of the camera (since camera is behind the net). Wait, the net is between the camera and the field. So the field is in front of the net, so the person is on the field, which is in front of the net. So when the camera looks through the net, the person is in the middle distance, in front of the net.

So the person throws the ball, which travels towards the net (so the ball is moving from the person towards the camera, passing through the net). So the ball comes through the net.

Now, in the video description:

After the black screen, the scene shows a blue net with a grassy field beyond. A person (small, distant) stands on the field and throws a ball. The ball moves forward through the net. The person remains in place. Camera is stationary, view through net.

Make it concise: The video begins with a black screen, then transitions to a view through a blue net. A person on a grassy field throws a ball toward the camera, which travels through the net. The person remains stationary in the background while the ball passes through the net. The camera maintains a fixed position with slight shake, capturing the scene from behind the net.

Wait, the user says "conclude with camera perspective and movement". The camera is behind the net, so perspective is through the net, fixed position, slight shake maybe. The video shows the net as a frame, so the camera is positioned so the net is the foreground, hence the view

A pitcher and a ball are visible; the ball is in motion due to being thrown (explicit physical force), and the pitcher’s locomotion is distinct. These objects are solid and clearly trackable.

The background elements (trees, grass, house) show no uniform shifting or fluid motion (e.g., no fire, water, or wind-driven movement). The net structure in the foreground is static.


A pair of hands presses the white and black keys of a large electronic keyboard, moving rhythmically to play music in a dark setting; the camera maintains a steady top-down view focused on the hands and keyboard, with minimal background detail visible.

Two hands (discrete solid objects) moving rhythmically on keyboard keys through explicit finger motion and pressure.

No shifting background elements observed; static keyboard and room environment with no fluid motion (fire, water, smoke, wind) present.


A hand reaches into a brown paper bag containing folded light blue clothing items, manipulating and pulling the garments from within the bag. The person’s arm is visible beside the bag. The camera maintains a close-up perspective with slight movement.

The hand manipulates the fabric bag to reveal and move a small object (likely an ear of corn), demonstrating explicit physical interaction.

No shifting background elements or fluid/environmental motion observed; the background consists of static skin and fabric being manipulated by the hand.


RAW CAPTION: Got it, let's break this down. First, the video starts with a kid in a green shirt and dark pants near a table with a laundry basket. Then, the kid moves towards the right, and a smaller child in light blue appears. The green-shirted kid walks away, then comes back, and the smaller child follows. Need to describe the motion chronologically.

Main subjects: two kids. First kid: green shirt, dark pants, moving. Second kid: small, light blue clothing, following.

Chronological order:
- Initial frame: green-shirted kid near table, then moves left (out of frame), then reappears, moves towards the smaller child who is on the right. Then the green-shirted kid walks away, and the smaller child follows. Wait, the video shows the green kid moving from right to left, then the smaller child comes in from the right, then the green kid walks back left, and the smaller child follows.

Spatial: table with laundry basket, chair with stuffed animal. Background minimal.

Camera: stationary, maybe slight shake, but the output says "camera perspective and movement". The video is a fixed shot, so "stationary camera".

Need to keep it concise. Let's structure:

A child in a green shirt and dark pants walks left from a table toward the camera, then turns and walks right while a smaller child in light blue clothing approaches from the right. The first child continues walking right, then turns left, and the smaller child follows. Background includes a wooden table with a laundry basket and scattered items. The camera remains stationary with slight shake.

Wait, check the rules: minimal background, so maybe don't mention table items except necessary. The rules say "background descriptions minimal unless essential for understanding motion". Here, the table with laundry basket might be important for context, but maybe just mention the room's main elements as needed.

Let's rephrase:

In a dimly lit room with a wooden table holding a laundry basket and other items, a child in a green shirt and dark pants walks left, then turns right and moves toward the camera. A smaller child in light blue clothing enters from the right, following the first child’s path. Both move across the room; the first child exits left, then re-enters and walks right again, with the smaller child trailing. The camera remains stationary with slight shake.

Wait, need to be more precise chronologically. Let's check the timestamps:

[0.0] Green-shirted kid is near a chair (right side), then moves left (toward camera), exits frame left. [1.4] Then the kid is gone, and a smaller child is near the right. Wait, no: frame 0, green kid is on the right, moving left (toward camera). Then frame 1.4, green kid is moving left, and the smaller child is on the right. Then frame 2.5, green kid is left, smaller child is center. Then frame 3.6, green kid is left, smaller child is right. Then frame 4.7, green kid is right, smaller child is left. Wait, maybe the sequence is:

- At 0, green kid is on the right (by the chair), moves left (toward the table), then exits left. But in frame 0, green kid is on the right, then frame 1: green kid walks left (out of frame), smaller child appears from right. Wait, frame 0: green kid is on right, moving left. Then frame 1: green kid is walking left (partially out), smaller child on right. Frame 2: green kid is left, smaller child is center. Frame 3: green kid walks back right, smaller child follows. Frame 4: green kid is right, smaller child follows.

Wait, the video shows:

First frame: green shirt kid (let's call him A) is on the right, moving left.

Second frame: A is moving left, and a smaller kid (B) appears on the right.

Third frame: A has exited left, B is center.

Fourth frame: A re-enters from left and moves right, B is right.

Fifth frame: A and B are together moving right.

Wait, maybe better to track positions:

- A starts near the right (chair area), moves left (toward camera). Then A leaves the frame to the left. B is in the right background. Then A re-enters from the left and moves right, B follows.

So chronological:

A child in a green shirt and dark pants walks leftward from the right side of the frame, exits left, then re-enters and walks right. A smaller child in light blue clothing enters from the right, follows A, and walks right

Two children are moving: one in a green shirt walks across the frame, and another in a blue shirt stands and shifts position.

Background elements (table, couch, walls) show no uniform shifting; no fire, water, smoke, or wind motion observed.


A man wearing a white t-shirt and black pants stands in a gym, holding a dumbbell in his right hand. He lifts the dumbbell upward, pauses briefly, then lowers it back down, repeating the motion. The camera remains stationary, capturing the scene with gym equipment visible in the background.

Brief description of background and ambient


Two individuals in black wetsuits and clear helmets initially hold a blue-and-yellow striped fish; as the video progresses, numerous striped fish swim around and in front of them, increasing in number. The fish move dynamically around the individuals' helmets, with some approaching closely while others swarm in the background. The camera maintains a close perspective with slight movement, capturing the interaction between the people and the fish.

Two divers and a school of blue and yellow striped fish (likely sergeant majors) are the discrete objects. The fish are swimming actively, while the divers are relatively stationary.

The background (rocks and water) is static. The water appears still, and the dominant motion is the school of fish swimming around the divers.


A single individual wearing a gray top and black pants executes a discus throw on a brown circular mat. They begin with a forward lean and extended arm, rotate clockwise while stepping, and complete the motion by releasing the discus. The camera maintains a fixed position throughout the sequence.

A person in athletic attire performs a rotational throwing motion (likely discus or hammer throw), exhibiting controlled body movements including running, spinning, and leg elevation.

Background elements (railing, windows, floor markings) remain static; no fluid/environmental motion (fire, water, smoke, wind) detected.


...<caption_output>  Need to make sure it's a paragraph, chronological, concise.  Final draft:  A dealer wearing a black vest, white shirt, and bow tie handles playing cards on a green blackjack table, first arranging the cards with his hands and then moving them across the table surface. Another dealer in similar attire is visible at a second table in the background. The camera remains static, capturing the main dealer’s actions from a frontal viewpoint. </think>  <caption_output>A dealer wearing a black vest, white shirt, and bow tie manipulates playing cards on a green blackjack table, first arranging the cards with his hands and then moving them across the table surface. Another dealer in identical attire is visible at a second table in the background. The camera remains stationary, focusing on the main dealer’s actions from a frontal perspective.

Dealer's hands and casino chips on the table exhibit discrete movement due to physical interaction (placing/chips)

Background elements (walls, ceiling lights) are static; no fluid or environmental motion observed.


RAW CAPTION: Got it, let's break this down. The video starts with a person in a black jacket holding a dog. The dog is light-colored, sitting on a table. The person is holding a clipper, and then the clipper is held near the dog's head. The text says to turn on the clipper and let the dog get used to the sound. Then there's a close-up of the clipper near the dog's face. Then the text changes to "Attaching and removing a guide comb".

Need to focus on the motion and behavior chronologically. First, the person holds the dog, then turns on the clipper, holds it near the dog. Then close-up of clipper near dog's face. Then the next step is attaching/removing guide comb, but the video shows the clipper being held near the dog, then the text changes.

Wait, the video frames: first frame shows person with dog, holding clipper. Then the person moves the clipper towards the dog's head. Third frame is close-up of clipper near dog's ear. Then fourth frame is close-up of clipper near dog's face. Then the text changes.

So the sequence: a person in black jacket holds a light-colored dog. The person turns on a clipper and holds it near the dog's head. The camera zooms in on the clipper near the dog's face. Then the next step is about guide comb, but the video might be showing the clipping process.

Need to mention appearance: dog is light-colored, sitting. Person in black jacket. Clipper is black and silver.

Spatial relationships: person is behind the dog, holding it. Clipper is held near the dog's head.

Camera movements: starts wide shot, then zooms in on the dog's face and clipper.

Background: minimal, so don't describe much.

Let's put it together:

A person in a black jacket holds a light-colored dog sitting on a table. The person turns on a black-and-silver clipper and holds it near the dog's head. The camera zooms in on the clipper positioned close to the dog's face as the person adjusts the clipper. The scene continues with the clipper near the dog, then the text changes to guide comb, but the action is the person familiarizing the dog with the clipper's sound.

Wait, the caption needs to be concise, chronological. Let's check the rules: focus on motion and behavior, appearance, spatial, conclude with camera perspective.

So:

A person in a black jacket holds a light-colored dog. The person turns on a black-and-silver clipper and holds it near the dog's head, moving it to the dog's face. The camera zooms in on the clipper close to the dog's face. Then the person adjusts the clipper, and the scene transitions to the next step involving guide combs.

Wait, but the video has the text "Attaching and removing a guide comb" as the next step, but in the frames provided, the video shows the clipper being held near the dog. Let's check the given frames.

Frame 0: person in black jacket, dog sitting, clipper in hand.

Frame 1: person moves clipper towards dog's head.

Frame 2: close-up of clipper near dog's head.

Frame 3: close-up of clipper near dog's face.

Frame 4: text "Attaching and removing a guide comb" appears.

So the sequence is: person holds dog, turns on clipper, holds near dog, then camera zooms to show clipper near dog's face, then the text changes to guide comb.

So the caption should be:

A person in a black jacket holds a light-colored dog seated on a table. The person turns on a black-and-silver clipper and holds it near the dog’s head, moving it toward the dog’s face. The camera zooms in to focus on the clipper positioned close to the dog’s face. Then the text changes to “Attaching and removing a guide comb,” but the primary action is the person familiarizing the dog with the clipper's humming sound.

Wait, but rule f says exclude text recognition. Oh right! Rule f: Exclude text recognition, named characters, or stylistic analysis.

So can't mention the text. So the text is not to be included. So the description should not refer to the text, just the visuals.

So:

A person in a black jacket holds a light-colored dog sitting on a table. The person turns on a black-and-silver clipper and holds it near the dog’s head, then moves it closer to the dog’s face. The camera zooms in on the clipper positioned near the dog’s face as the person adjusts the clipper. The scene transitions to a close-up of the clipper near the dog’s head

The person is moving the electric clippers to groom the dog. The dog is held and remains mostly stationary, but the person's hand and the clippers are in motion.

The background (wall, equipment) is stationary with no fluid or environmental motion (fire, water, smoke, wind).
