A young child in a gray shirt, black shorts, and blue sandals sits on light-colored tiles, holding a blue toy shaped like a cartoon character with a bottle. The child manipulates the toy, moving it from their lap to near their face and back. The camera remains in a steady top-down position.

A child is manipulating a blue toy car, making small, controlled movements with hands and head while seated on the floor. The child and toy are the only moving discrete objects, with motion originating from physical interaction.

The tiled floor and wall background remain static with no shifting or fluid motion (e.g., no wind, water, or smoke). Background elements are fixed and stable throughout the clip.


A person in a brown jacket, blue jeans, and dark boots crouches on a blue stool beside a concrete block, holding the leg of a light-colored medium-sized pig standing on the block. The person then lowers their hand toward a plastic bucket on the hay-covered ground, appearing to feed or interact with the pig. The camera remains static with minimal movement, capturing the scene from a fixed angle.

Person (wearing beige jacket, blue bucket) and goat move through discrete interactions (hand gestures, cup handling, goat head movement).

No shifting background elements (walls, hay pile remain stationary across frames). No fire, water, smoke, or wind motion detected.


An athlete in a black and yellow uniform jumps over a horizontal bar, landing on a yellow mat, then stands up and begins walking away from the bar area toward the gym’s interior, passing other individuals. The camera starts with a high-angle perspective of the jump and transitions to follow the athlete as they move.

Athlete (in dark/yellow uniform) falls onto mat, then rises, walks across gym floor, and interacts with multiple individuals (coaches/officials). Movement is driven by locomotion and physical impact.

No shifting background or fluid motion observed. Gymnasium walls, floor tiles, and structural elements remain static in both segments. No fire, water, smoke, or wind activity present.


A seated individual in a black cape has their hair cut by a standing person wearing gloves and a black top; the standing person manipulates the seated individual’s hair, adjusts their position, and then steps back. The standing person moves toward a red table with supplies to the left. The scene occurs under a white tent with a gravel ground; the camera remains static with minimal movement.

Two discrete objects: a seated individual (wearing a cape) with minimal head movement, and a standing individual performing hand-based actions (applying product, walking to/from a table). The standing individual's locomotion and arm movements are the primary object-driven motions.

The background elements (red tablecloth, white tent structure, patterned ground) remain static with no discernible fluid or environmental motion (e.g., no fire, water, smoke, or wind-driven swaying).


Two children stand near a kitchen refrigerator; the taller child in a white shirt and dark pants runs forward toward the camera, passing in front of a colorful baby activity center, while the shorter child in pink remains stationary by the fridge. The camera remains static.

A person (discrete solid object) moves from the background toward the camera, exits the frame, and no other distinct objects exhibit significant motion.

Background elements (fridge, chairs, furniture) remain static throughout the clip; no fluid or gaseous motion (fire, water, smoke) is present.


RAW CAPTION: Got it, let's break this down. The video shows a room with several people. First, there's a group of people standing around, some in the background. Then, a person in a green shirt and dark pants moves into the center. Wait, the description says "main subjects in chronological order." Let's check the frames.

Frame 0: People in the room, some standing, some near a backdrop. Frame 1: Similar, maybe shifting positions. Frame 2: The person in green (or maybe a different shirt) is walking towards the camera. Wait, the user's description: first frame shows a group, then a person in green shirt and dark pants moves, then another person in red shirt runs? Wait, the user's video frames: [0.0] shows a group, [1.4] same, [2.5] someone in green shirt (maybe) moves, then [3.5] another person in red runs towards camera? Wait, need to parse the video.

Wait, the user provided 5 frames (0.0 to 4.7 seconds). Let's read the user's description:

At 0.0: people in a room, some standing, some sitting (maybe on a bench?), backdrop with a whiteboard or something. Speakers on tripods.

At 1.4: similar, people moving.

At 2.5: a person in a green shirt (maybe) and dark pants is moving.

At 3.5: a person in a red shirt is running towards the camera.

Wait, the key is to describe motion chronologically. Let's list the actions:

- Initial frame: several people are gathered, some standing near speakers, others sitting or standing in the middle.

- Then, a person (appears to be male, wearing a green shirt and dark pants) moves forward across the room.

- Then, another person (red shirt, pants) runs towards the camera.

Wait, need to check the movement. The user's video description:

[0.0] people in room, [1.4] similar, [2.5] person in green shirt moves, [3.5] another person in red runs, [4.7] the person in red continues.

Wait, the user's frames:

<0.3> first frame: group of people in a room, some near speakers, some in center.

<1.4> same, but people moving.

<2.5> person in green shirt (maybe) walks towards camera? Or is it the same person. Wait, maybe the main actions are:

- A group of people are standing in a room.

- Then, a person wearing a green shirt and dark pants moves from the background towards the camera.

- Then, another person in a red shirt runs towards the camera.

But need to be precise. Let's check the frames:

Frame 0: people standing, some near a backdrop, speakers on left.

Frame 2: a person (green shirt, dark pants) is in the middle moving.

Frame 3: another person (red shirt, blue jeans) is running towards camera.

Wait, the user's description:

" <0.3 seconds> ... <1.4> ... <2.5> ... <3.6> ... <4.7> ... "

In the frame 2.5: "a person in a green shirt and dark pants walks towards camera" (since the description says "a person in a green shirt and dark pants moves into the center").

Wait, let's parse the user's input: the video shows:

- First, people are gathered in a room (background: speakers, a few people standing).

- Then, a person in a green shirt and dark pants moves from the background towards the camera.

- Then, another person in a red shirt runs towards the camera.

Wait, the user's frame descriptions:

At <2.5> it says "a person in a green shirt and dark pants moves into the center".

At <3.6> "a person in a red shirt and blue jeans runs towards camera".

So chronological order:

1. Initial scene: multiple people stand in a room (some near speakers, some in the center), including a person in red shirt and blue jeans (but maybe not, the red shirt is later).

Wait, the main subjects are the people moving.

So first, the room has a group of people. Then, a person (green shirt, dark pants) moves forward. Then, another person (red shirt, blue jeans) runs towards the camera.

Now, spatial relationships: the green shirt person is in the middle area, then the red shirt person comes from the right (since in frame 3.6, it's

A person in the foreground performs breakdancing movements (spinning, bending, locomotion), while other people stand as stationary observers in the background.

Background elements (walls, floor, standing individuals) show no significant shifting or environmental motion (fire, water, smoke, wind); all static background features remain fixed relative to the scene.


A video opens with a green screen on the left, a chair, and people near it before transitioning to a couple (man in white shirt and black pants; woman in black dress) dancing in a circular marked area. They move together in a coordinated dance, rotating and stepping while surrounded by an audience seated on bleachers and the ground. The camera remains steady, focusing on their motion throughout.

Two individuals (a man and a woman) are performing a dance routine with coordinated stepping, turning, and positional changes. Their motion is discrete, solid, and attributable to locomotion (e.g., walking, pivoting) rather than environmental forces.

The background consists of a static green building, chairs, and seated spectators with minimal movement (e.g., subtle shifts in the crowd). No fire, water, smoke, or significant wind-driven motion is visible. Background elements show no uniform shifting.


Two hands, one with a black wristband, assemble a colorful jigsaw puzzle. The left hand positions a blue piece while the right hand adjusts a pink piece; they then fit pieces together, with scattered puzzle fragments around the partially completed image on a light surface. The camera maintains a static top-down perspective throughout.

Hands manipulate distinct solid puzzle pieces, performing grasping, lifting, and placement actions to fit pieces into the puzzle grid.

No shifting background elements or fluid/environmental motion observed. The table surface and static puzzle pieces remain fixed throughout the video.


A person in dark winter clothing walks along a snow-covered path, moving from right to left near a utility pole. The individual passes in front of a brick building with a ladder leaning against its side. The scene features scattered debris and snow-covered ground in the background. The camera maintains a static position with a slight shake throughout the sequence.

A single person is actively shoveling snow, moving their body and shovel in a consistent, discrete motion. The person's locomotion and tool use demonstrate explicit physical interaction with the environment.

The building, ladder, and snow-covered ground show no significant shifting or fluid motion. No fire, water, or smoke is visible; environmental elements (trees, snow) remain static.


RAW CAPTION: Got it, let's break this down. The task is to create a concise chronological paragraph about the video. First, identify the main subjects: three workers. Let's check their actions. The video shows them working on a wall, applying plaster or cement.

First frame: left worker in gray shirt, dark shorts, bending over. Right worker in yellow shirt, yellow helmet, gray pants, also working. Third worker in red cap, maybe blue shirt, on the right. But the problem says main subjects, so focus on the main ones. The video starts with them working on the wall.

Chronological order: they are applying plaster. Let's describe each action step by step. The workers are using trowels. The first worker (gray shirt) is on the left, scooping or spreading plaster. The yellow-shirted worker is next to him. Both are on scaffolding, working on a brick wall. The wall has sections with plaster (gray) and brick (white).

Need to mention appearance: number of people, colors. Let's count: two main workers visible in the frames (the third might be partially visible). Wait, in the first frame, there's a third person on the right, but maybe not the focus. The problem says main subjects, so probably the two prominent ones.

Spatial relationships: left worker (gray shirt, dark shorts) and right worker (yellow shirt, yellow helmet, gray pants) are working side by side on the wall. The wall is behind them, scaffolding in front.

Background: minimal, just the wall and some rocks or trees in the distance. But rules say keep background minimal unless essential. So maybe just note the wall and scaffolding.

Camera perspective: the video is shot from a fixed position, looking at the workers. No movement mentioned, so probably static.

Now, structure the caption:

Start with chronological order. Describe their actions:

"Two construction workers on a scaffolding platform apply plaster to a brick wall. The worker on the left, wearing a gray shirt and dark shorts, bends over, using a trowel to spread gray mortar onto white bricks. To his right, a worker in a yellow shirt, yellow helmet, and gray pants similarly spreads mortar. Both workers repeatedly dip their trowels into red containers on the platform, then apply the material to the wall. The background shows the partially plastered wall and distant rocky terrain. The camera remains stationary, capturing the workers’ repetitive motion."

Wait, check the rules: be concise. Let's make it shorter.

"Two workers on scaffolding apply mortar to a brick wall. Left: gray shirt, dark shorts, bends to spread mortar from red container. Right: yellow shirt, yellow helmet, gray pants, repeats the action. They alternate dipping trowels into containers and applying mortar to the wall. Background includes the textured wall and distant rocks. Camera is static."

Wait, need to be chronological. Describe the sequence. Let's see the frames: frame 0-5, each worker is doing the same action. So the sequence is the workers scooping mortar, spreading, repeating.

Make sure to mention the key elements: number of subjects, their actions step by step.

Another try:

"Two construction workers stand on a scaffolding platform, applying gray mortar to white brick sections of a wall. The worker on the left (gray shirt, dark shorts) repeatedly dips a trowel into a red container, then spreads the mortar onto the wall. The worker on the right (yellow shirt, yellow helmet, gray pants) performs the same action. Both workers are positioned side by side, facing the wall, with the scaffolding railing in front. The camera remains fixed, capturing their consistent motion."

Check rules: focus on motion and behavior chronologically. So describe the action order: dipping, spreading. Also, mention appearance: colors. Number: two main workers. Spatial: left and right on scaffolding. Background minimal (wall and maybe some trees/rocks, but don't elaborate too much). Camera: static.

Avoid mentioning the third worker in the background since they're not the main focus (the problem says main subjects, and the other one is partially visible but not the main).

So final draft:

"Two construction workers on scaffolding apply mortar to a brick wall. The worker on the left, wearing a gray shirt and dark shorts, bends over, repeatedly dipping a trowel into a red container and spreading gray mortar onto the wall. To his right, a worker in a yellow shirt, yellow helmet, and gray pants does the same. Both workers alternate between scooping mortar and applying it to the wall. The background shows the partially finished wall and distant rocky terrain. The camera remains stationary, capturing their synchronized actions."

Check for brevity. Make sure it's chronological. Let's see: dipping, spreading. Yes.

Is there a third worker

Two workers (one in blue, one in yellow) exhibit discrete locomotion: bending over, standing, and applying mortar to the wall. Their movements are distinct physical actions without background blurring.

The stone wall and distant trees in the background show no shifting or fluid motion. No fire, water, smoke, or wind is visible; the environment remains static.


Two individuals in white karate uniforms engage in a training sequence. The left person leaps into the air, extending their leg upward to strike the pad held by the right person. After making contact, the left individual lands and steps back, while the right person maintains the pad's position and subsequently steps backward. A third person in white uniform stands with arms crossed in the background. The camera remains static throughout the sequence.

Two people in white uniforms are moving: one performs a high kick (Dwiro dora an tchagi) and another executes a jump kick (CP sauté, avec élan). Their motion is due to deliberate physical locomotion (kicking, jumping) and muscle forces, with clear bounding box tracking.

The background (walls, floor, gym equipment) shows no shifting or fluid motion. There are no fire, water, smoke, or wind elements. The environment is static with no ambient environmental phenomena.


A person in a black karate uniform and barefoot stands on blue mats, executing high kicks in sequence. Starting in a defensive stance, they raise their right leg high in a roundhouse kick, then lower it, followed by a high kick with the left leg. A black chair remains positioned to the right of the subject throughout. The camera maintains a static front perspective with beige curtains in the background.

A person in a black uniform performing martial arts movements (kicks, stances) with clear discrete object motion.

Background (curtain and floor pattern) is stationary; no fire, water, smoke, or wind motion observed.


In a small shop, a seated customer wearing a yellow cape receives a haircut from a standing barber in a gray vest and checkered shirt. The barber uses his hands to trim the customer’s hair, moving them across the head; after a few seconds, he steps back slightly. The camera maintains a static shot throughout.

The barber's hands and body move to trim hair (explicit physical action), while the customer's head moves slightly (leaning forward and turning). Both are discrete solid objects.

The background (wall, window, blue table) remains static with no shifting, fluid, or environmental motion. No fire, water, smoke, or wind is present.


Two young girls with dark hair sit in a red shopping cart; one has a hair bow. The girl on the right touches the left girl’s face, then both face each other while the left child looks up. The cart remains stationary in a store aisle with shelves visible in the background. Camera perspective is close-up and slightly shaky, maintaining focus on the cart and its occupants.

Two children in a shopping cart exhibit subtle movements (hand gestures, shifting posture) consistent with discrete human locomotion and interaction within the cart.

Background shelves and items remain static with no uniform shifting or fluid/environmental motion (fire, water, wind, smoke) detected.


A large herd of brown, black, and white cattle moves slowly across a grassy field, guided by riders on horseback. The camera pans left, following the herd’s movement as the cattle gradually shift direction under the riders’ guidance, maintaining a loose formation with some individuals leading while others trail behind.

A herd of cows (brown, black, white) is moving slowly across the grassy field; their locomotion is distinct and driven by their own movement.

Background elements (sky, distant horizon, grassy field) remain relatively static; no fluid environmental motion (fire, water, smoke, wind) is observed.


RAW CAPTION: Got it, let's break down the video frames. First frame: a hand (dark skin tone) stirring a beaker with a stirrer. The beaker is on a white surface, background is beige. Then the text "Mix in recommended ratio" appears, but I need to ignore text per the rules. Next frame: a person in an orange tank top, wearing a white glove, using a spray gun on a wooden circular object (maybe a table or board) against a teal background. Then another frame shows the spray gun applying coating to a wooden chair leg.

Chronologically: first, hand stirring in a beaker. Then, person spraying wood coating on a wooden surface. Then, spraying on a chair leg. Wait, the frames are 0 to 5 seconds. Let's list the actions in order.

Frame 0: Hand (dark skin) stirs a beaker (clear glass, contains liquid) on a white table. Background beige.

Frame 1: Same hand, stirring, text changes but ignore text.

Frame 2: Transition to a person (orange top, white glove) using a spray gun on a circular wooden object. Background teal.

Frame 3: Same person continues spraying on the wooden object.

Frame 4: Close-up of spray gun applying coating to a wooden chair leg.

Now, summarize chronologically:

First, a hand stirs a beaker on a white surface. Then, a person in an orange tank top uses a spray gun to apply coating to a wooden circular surface, followed by spraying onto a wooden chair leg.

Need to mention appearance: hand (dark skin tone), beaker (clear glass, liquid), person (orange tank top, white glove). Spatial: hand over beaker; person spraying on wooden surface (circular and chair leg).

Camera perspectives: first frame is close-up of hand and beaker, then cut to medium shot of person spraying, then close-up of spray gun on chair leg.

Background: minimal, beige then teal.

Check rules: focus on motion, chronological, appearance, spatial, conclude camera.

So:

A hand with dark skin stirs a clear glass beaker containing liquid on a white surface. Then, a person wearing an orange tank top and white glove sprays a coating onto a circular wooden surface against a teal background. The person continues applying the coating to a wooden chair leg. The camera starts with a close-up of the hand and beaker, then shifts to a medium shot of the person spraying, and finally focuses on the spray gun applying coating to the chair leg.

Wait, the rules say "conclude with camera perspective and movement". So need to end with that.

Let me check the frames:

0.0: hand stirring beaker (close-up, static)

1.4: same hand, text (but ignore text, so motion same)

2.5: person spraying on circular wood (medium shot, teal background)

3.6: same person, still spraying on the same wooden circular object? Wait the third frame (frame 3) shows applying to a wooden circular surface, then frame 4 is the chair leg.

So chronological order of actions:

1. Hand stirs beaker.

2. Person uses spray gun on wooden circular surface.

3. Person uses spray gun on wooden chair leg.

Camera perspectives:

- First scene: close-up of hand and beaker (top-down? No, seems eye-level close-up).

- Second scene: medium shot of person spraying on circular wood.

- Third scene: close-up of spray gun on chair leg.

Wait, the first frame is a close-up of the hand over the beaker. Then the scene changes to a person spraying.

So the caption should be:

A hand with dark skin stirs a clear glass beaker filled with liquid on a white surface. Then, a person in an orange tank top and white glove sprays a wood coating onto a circular wooden surface against a teal background. The person continues spraying the coating onto a wooden chair leg. The camera captures a close-up of the hand stirring the beaker, transitions to a medium shot of the person spraying, and ends with a close-up of the spray gun applying coating to the chair leg.

Wait, check the rules: "conclude with the camera perspective and movement". So need to describe the camera's position and movement at the end. The last frame is a close-up of the spray gun on the chair leg, so camera perspective is close-up.

Also, the rules say "Exclude text recognition, named characters, or stylistic analysis." So don't mention the text.

Let me rephrase to be concise:

A hand stirs a clear glass beaker with a liquid on a white surface. Then, a person

Discrete solid objects include a hand stirring a beaker (0-1.9s) and a gloved hand/spray gun applying wood coating (2-5s). These objects move due to explicit physical actions (stirring, spraying).

The background elements (walls, wooden surfaces) are static and show no uniform shifting or fluid motion. No fire, water, or wind-driven phenomena are present.


A man in a red polo shirt plays a light brown wooden lute, his fingers moving rhythmically over the strings while his left hand positions the strings on the neck. The lute features a circular sound hole and is held vertically against his torso. He remains seated, with framed pictures and a lamp visible minimally in the background. The camera maintains a static, close-up perspective focused on the man and the instrument throughout.

The man in the red shirt is the primary discrete object, with his hands and upper body moving to play the lute. This motion is due to muscle-driven actions and is easily trackable via bounding boxes.

The background (walls, framed pictures, shelf) shows no shifting or fluid motion. No fire, water, smoke, or wind is visible, indicating no ambient environmental motion.


A pair of dark-skinned hands manipulates a purple yarn and metallic crochet hook, inserting the hook into a loop and pulling through to form stitches. The hands work on a pink textured fabric background, with the camera providing a steady close-up view focused on the crocheting motion.

The calendar background is static with no shifting elements or fluid/environmental motion (fire, water, wind).


A person in dark clothing enters the frame from the left, moving across the concrete pool deck toward the pool edge, then walks away. Another person in dark clothing appears from the right, walking toward the left. The camera remains in a static top-down position throughout the sequence, capturing the construction site with minimal background details.

Discrete solid objects (people) are moving across the concrete surface; a person is seen walking and performing tasks (e.g., handling materials, moving between areas).

Static background elements (concrete surface, walls, debris) remain fixed with no uniform shifting; no fire, water, smoke, or wind-induced motion observed.


A boy in a green shirt and patterned shorts sits near a window with greenery outside; a woman in blue jeans sits to his right holding a book. The boy stands, moves toward a smaller child in a red top and white pants, lifts them into a hug, and they embrace in front of a colorful box. The woman remains seated on the right. The camera has a slight shake with a stationary view.

Two children (solid, discrete objects) interact physically: one lifts the other, embraces, and shifts position. Their motion results from explicit physical forces (hugging, lifting) and locomotion, clearly trackable as discrete object movement.

The background includes a window with static greenery outside; no significant fluid motion (fire, water, smoke) or wind-blown elements dominate. The window frame and curtain remain relatively fixed, with no uniform shifting indicating environmental fluid dynamics.


A man in a blue denim shirt and black hat assists a young girl in a pink jacket as she sifts material in a black pan; his hands move the pan while another person's hand assists from the left. The camera shifts to an outdoor scene where two individuals walk away from a signpost—one in a green jacket with a green bag, the other in a blue jacket—before cutting to an interior setting where a person hands a green box to another individual. The camera moves from close-up to wide shot, then to an interior perspective.

Discrete objects (people) are moving due to locomotion (walking), pouring actions, and handshakes. The motion is consistent with physical forces applied by the individuals.

The background elements (walls, signs, trees) are stationary in all scenes. There is no dominant fluid or environmental motion (fire, water, smoke, wind) in any segment.


A person with long dark hair, wearing a pink top and black pants, stands against a light-colored wall on a wooden floor. They swing and rotate their hair in a fluid motion, lifting it above their head and moving it side to side. The camera remains stationary, capturing the action from a fixed angle.

The main discrete object is a person (woman) moving her long hair in a circular motion due to her own body movement. The hair is attached to the person and moves as a result of her physical actions.

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


A shirtless man in dark shorts runs toward a small brown ball on a grassy field, kicks it forward, then walks away. Behind him is a large stadium structure. The camera remains stationary.

The camera remains stationary, capturing the motion from a medium angle.

A person in athletic wear performs a weightlifting exercise on a red machine, lifting a barbell overhead and lowering it in a controlled motion. The motion is caused by the person's physical exertion.

The gym background (dumbbell racks, exercise balls, walls) is stationary with no uniform shifts or fluid/environmental motion. No fire, water, smoke, or wind is present.


A hand holds a white paper with a light floral design, guiding a metallic tool along the pattern's lines. The tool moves steadily across the paper, tracing or cutting the intricate shapes. The hand and tool remain in close proximity to the paper, which rests on a green grid background. The camera maintains a close-up, stable perspective focused on the hand's motion and the paper's surface.

The scissors and the paper are moving due to cutting action; the hand is holding and manipulating the paper and scissors.

The background is a stationary green grid cutting mat. No ambient environmental motion (fire, water, smoke, wind) is present.


Two workers in white uniforms and aprons handle pink sausages in a factory setting; the worker on the right manipulates a metal rack holding coiled sausages, adjusting their position while the worker on the left operates a funnel-shaped machine. The camera zooms in on the right worker's hands as they reposition the sausages on the rack, maintaining focus on the action with minimal background detail visible. The perspective shifts slightly closer to the rack and hands during the sequence.

Two workers manipulate solid sausage links: one coiling/uncoiling sausages on a conveyor system while the other operates a hopper. The sausages move due to hand manipulation and conveyor mechanics.

The factory environment (walls, machinery, hopper) remains static across both segments; no fluid motion (fire, water, smoke) or wind is present. Background elements do not shift uniformly.


A dark-skinned hand holding a yellow marker appears over a yellow sheet of paper, moving to write on its surface. The hand continues the writing motion as the video progresses. The camera maintains a top-down perspective with slight movement.

A hand holding a yellow pen is writing on a notebook page. The pen's motion is deliberate and controlled, indicating human locomotion for writing.

Background (wall and notebook edges) appears static with no uniform shifting; no fire, water, or wind motion observed. No fluid/environmental elements dominate.


A boy wearing a green sweater and white shirt plays a light-colored recorder while standing in the foreground; multiple students walk past him in the background. The camera remains static.

The boy plays the flute: his lips and fingers move rhythmically to produce sound. A person in the background walks across the scene.

The background (walls, decorations, and classroom furniture) remains stationary with no fluid or gaseous motion. A person walks in the background, but this is discrete object motion, not ambient environmental.


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

The main subject here is a person playing a red electric guitar. Let me check the video frames. In the first frame, the person is holding the guitar, maybe adjusting it. Then, they start playing, moving their hands up and down the neck. The background has a fridge with magnets and a wall with posters, but the rules say to keep background minimal unless essential. So I should mention the fridge and posters briefly but not dwell on details.

Wait, the rules say to exclude text recognition, so even if there's text on the fridge, I shouldn't mention it. The user wants focus on motion and behavior. The person is wearing a white tank top and dark pants. The guitar is red, which is a key detail.

Chronicling the actions: the person starts by holding the guitar, then plays it. The movements are their hands on the fretboard and strumming. Spatial relationships: the person is standing in front of the fridge and posters. The camera is static, no movement mentioned. The user says to describe the camera perspective and movement at the end.

Wait, the output format must be in specific tags. Let me structure it: start with the person's actions, mention appearance, spatial context, then camera. Keep it concise.

Check if there's any other objects. The amp is on the right, but maybe too much detail. Focus on main subject. The person moves slightly while playing, maybe shifting position a bit. No text recognition needed. Avoid named characters, so just "a person".

Let me draft:

"A person in a white tank top and dark pants plays a red electric guitar, moving their hands along the fretboard and strumming. They stand in front of a white refrigerator adorned with magnets and a wall with posters. The camera remains static, capturing the subject from a frontal perspective with no noticeable movement."

Wait, but the rules say to mention spatial relationships. The fridge is to the left, posters on the wall. The amp is to the right. But maybe minimal background. Let's see. The rules state "keep background descriptions minimal unless essential for understanding motion." Since the motion is playing the guitar, maybe the fridge and posters are just part of the setting but not essential. However, the fridge has magnets, which might be part of the scene. Hmm. Maybe "in a room with a refrigerator and posters on the wall."

Wait, the video starts with the person holding the guitar. Then, in the next frames, they adjust the guitar and start playing. The movement is the person moving their hands on the guitar, maybe shifting position slightly. The caption needs to be chronological. So: begins by holding the guitar, then plays it, moving hands up and down the neck.

So: "A person wearing a white tank top and dark pants holds a red electric guitar. They adjust their stance and begin playing, moving their left hand along the fretboard and right hand strumming. The subject remains positioned in front of a refrigerator with magnets and a wall covered in posters. The camera maintains a static frontal view with no noticeable movement."

Wait, but "begins playing" might not be accurate. The frames show them starting to play, so maybe "begins strumming and manipulating the guitar." Also, check the number of subjects: only one person. Make sure to mention the guitar's color and the person's clothing.

Another check: "concise, chronological paragraph". So start with the action, then follow the sequence. The first frame shows the person holding the guitar, then they play. So "Holding a red electric guitar, a person in a white tank top and dark pants begins playing, moving their hands up and down the fretboard and strumming. They stand in front of a refrigerator and a wall with posters. The camera remains stationary."

But need to check if "stationary" is correct. The user says "conclude with camera perspective and movement". So "static, frontal perspective with no movement".

Wait, in the provided example, the video shows the person moving their hands. Let me ensure the caption covers the motion. So the key motions are the hands moving on the guitar.

Possible final draft: "A person in a white tank top and dark pants plays a red electric guitar, moving their left hand along the fretboard and right hand strumming. They stand in front of a refrigerator with magnets and a wall of posters. The camera remains static, capturing the subject from a frontal view without movement."

But the rule says "briefly describe their appearance and number". So maybe "a person in a white tank top and dark pants". Correct.

Check if there's any mention of text. The fridge has text, but rule f says exclude text recognition. So don

A person is playing an electric guitar, with hand and body movements due to playing the instrument.

Background elements (refrigerator, wall) are static; no fluid or environmental motion (fire, water, smoke, wind) detected.


From a top-down perspective, a pair of hands chops a white ingredient on a wooden cutting board, then transfers the pieces into a clear glass bowl with a green lid. The hands subsequently handle a red ingredient, cutting it on the same board before moving toward other bowls. The scene remains static with no camera movement.

Discrete solid objects: hands (chopping, moving items), vegetables (being chopped, transferred), knife, and bowls (receiving/holding food). These objects move due to explicit physical interactions (chopping, placing).

Background elements (kitchen items, bowls, cabinets) remain static; no fluid/environmental motion (fire, water, smoke, wind) is present.


The video opens with a blurry close-up of a dark, shiny object on a wooden surface, then transitions to hands carving an orange pumpkin, scooping out its insides. The hands, positioned in front of the pumpkin, work with a pink carving tool visible on the table, amidst scattered newspapers and miscellaneous items in the background. The camera remains handheld with slight shake throughout the sequence.

Discrete solid objects (hands) are moving to carve and manipulate the pumpkin, with visible motion from cutting actions and tool handling.

Background elements (table, pumpkin) show no uniform shifting or fluid motion (fire, water, wind). The environment appears static with no dominant ambient environmental motion.


A person in a black dress with a white collar stands behind a seated individual with dark hair, massaging their head. The standing person’s hands move rhythmically across the seated person’s head in an upward and downward motion. The seated person remains still, facing right. The background features a plain white wall and brown carpet. The camera remains static in a medium shot throughout.

Two individuals are visible: one person (seated) with hair being manipulated by another person (standing). The standing person's hands move over the seated person's head and hair, exhibiting controlled, discrete motion.

Background elements (wall, carpet) remain static with no uniform shifting; no fluid or environmental motion (fire, water, smoke, wind) present.


A man in a white polo shirt, white cap, and beige pants stands on a green golf course holding a golf club. He bends forward to address a ball on the ground, positions himself, and swings the club. The background includes a grassy fairway and distant trees. The camera remains static, capturing his movements from a frontal perspective.

The golfer (human) and golf club move due to physical forces (swing motion). The golfer's body shifts and the club rotates through the air, with clear bounding box tracking.

The background (golf course, trees, sky) is static with no significant ambient motion (e.g., wind, water, smoke). The grid transition effect is an editing artifact, not environmental fluid motion.


Several people in black shirts and white pants stand on a grassy field; a person in the foreground walks toward the camera while holding a bat, then swings it. Others remain in the background. The camera follows the foreground subject with minimal movement.

Discrete objects: People walking and swinging a bat. The bat's motion is due to the physical swing of the player.

Background elements (grass, fence) remain relatively stable without uniform shifting; no fluid or wind motion observed.


A person wearing dark shorts plays a light brown acoustic guitar, strumming with their right hand while pressing strings with their left hand on the fretboard. The guitar is held horizontally in front of the person, with a bed, keyboard, and lamp visible in the background. The camera remains stationary throughout the sequence.

A person (wearing dark clothing) is playing an acoustic guitar. The left hand is moving along the fretboard and the right hand is strumming/plucking the strings, indicating controlled motion from the physical act of playing.

Background elements (bed, wall, lamp) are static and show no shifting. No fluid/environmental motion (fire, water, smoke, wind) observed.


RAW CAPTION: Got it, let's tackle this. First, I need to observe the video. The main subjects are people on a grassy field. Let's see the sequence.

Start: A person in a dark shirt (maybe player) runs from the left towards the right. There's someone with number 30 standing near a yellow bucket, wearing a dark shirt. Another person in the foreground with their hand on their head, dark shirt, maybe a spectator. The runner is moving towards the person in 30.

Then, the runner approaches the person in 30. Maybe they're doing a drill or something. The person in 30 is holding a glove, so maybe baseball or softball. The runner gets to the person in 30, then maybe runs past? Wait, the video has a few frames. Let's check each frame.

Frame 0: Person running from left (player) towards right. Person 30 standing near bucket. Spectator with hand on head.

Frame 1: Runner continues towards person 30.

Frame 2: Runner is closer to person 30.

Frame 3: Runner passes person 30? Wait, no. Wait, the runner moves towards the bucket? Or the person with 30. Wait, the person in 30 is standing by the bucket. The runner comes in, then the runner is near the bucket, and maybe stops? Wait, maybe it's a base running drill. Let's think.

Chronicology: A runner (dark shirt, light pants maybe) starts from left, runs across the field towards a person wearing a dark shirt with number 30. The person with 30 is standing near a yellow bucket and some cones. As the runner approaches, the person with 30 is holding a glove and moves slightly. There's a spectator in the foreground with hand on head. Then the runner passes by the person in 30? Or maybe the runner is coming to base.

Wait, in the video, the runner moves from left to right. The person with 30 is on the right side near the bucket. The runner approaches, then maybe stops or interacts. The spectator is on the left, hand on head. Then the runner goes past the person in 30? Wait, frame 4: the runner is moving away from the person in 30? Let me check.

Looking at the frames:

0: Runner on left, moving right. Person 30 on right, near bucket. Spectator on left, hand on head.

1: Runner closer to center. Person 30 still there.

2: Runner is approaching person 30, who is now moving slightly. Spectator still there.

3: Runner is near person 30, person 30 is moving towards the runner. Maybe the runner is tagging out?

Wait, the runner is moving towards person 30, then after passing, maybe they continue. Wait, frame 3 shows the runner getting closer to person 30, then in frame 4, the runner is moving past person 30, and then frame 5, the runner is further right, moving away.

Wait, maybe it's a baseball/softball drill where the runner is advancing to a base. The person in 30 is likely a fielder. So the sequence is: runner starts at left, runs towards the fielder (30), who is standing near the bucket, then the runner continues past.

Appearance: Runner is wearing dark shirt, maybe light pants. Person 30 is dark shirt with number 30, wearing a glove (baseball glove). Spectator is dark shirt, hand on head.

Spatial relationships: Spectator is to the left of the runner initially. Person 30 is to the right of the runner's path, near the bucket.

Background: Grassy field, fence with logos, trees. Minimal description as per rules.

Camera perspective: The camera is positioned at a low angle, maybe on the ground, since the field is flat. It's stationary, no obvious movement.

Now, putting it all together in chronological order.

First, a person in a dark shirt and light pants runs from the left side of the frame toward the center, passing a person wearing a dark shirt with the number 30, who stands near a yellow bucket on the grass. A spectator in a dark shirt sits to the left with their hand on their head. As the runner approaches the person in 30, the person in 30 slightly shifts position while holding a glove. The runner continues moving past the person in 30, heading toward the right side of the frame. The camera remains stationary throughout, capturing the scene from a ground-level perspective.

Two people engaged in physical movement: one person runs across the frame (left to right), another person (in dark clothing) interacts with an object (likely a ball) via throwing/catching motion. The ball is also in motion.

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


A pair of hands manipulates a small green knitted object, using a metal needle to pull a red thread through the fabric. The right hand holds the needle while the left hand steadies the green piece, which has a textured, crocheted surface. The needle moves through the fabric, drawing the red thread to tighten a stitch. In the background, a larger blue and red knitted item rests on the wooden surface. The camera maintains a close-up, steady perspective on the hands and work, focusing on the detailed stitching process.

Hands and knitting needles are moving as solid objects, manipulating red yarn through physical actions (looping, pulling) consistent with knitting.

Background elements (wooden surface, knitted objects) are static with no uniform shifting or fluid motion. No fire, water, smoke, or wind is visible.


A person in a pink shirt and dark pants ascends a vertical rope, moving upward from the lower section toward the ceiling with intermittent pulling motions. The camera remains static with slight shake, capturing the ascent against a colorful mural background.

A person in a pink shirt is swinging from the ceiling by their hands, exhibiting pendulum-like motion due to their own physical forces. The motion is discrete and trackable.

The ceiling lights and wall mural remain static throughout, showing no shifting or environmental fluid motion (fire, water, smoke, wind). No ambient environmental effects dominate.


A person with dark hair, wearing a brown sweater over a green checkered shirt, is seated indoors eating a sandwich. They bring the food to their mouth, take bites, and chew while seated at a table. In the background, other people are visible at tables and chairs, with a window providing light. The camera maintains a close-up, slightly shaky perspective focused on the person eating.

Person in foreground exhibits discrete hand-to-mouth motion (chewing/eating) with clear, localized movement of the hand and mouth region.

Indoor setting with static furniture and distant people; no shifting background elements, fire, water, smoke, or wind detected.


A hand holding a yellow paintbrush with a black tip applies blue watercolor to a textured painting surface, moving the brush in smooth strokes. The scene transitions to a top-down view of an art setup, revealing a watercolor palette with mixed hues, a paintbrush, a water cup, and a paper towel arranged on a textured surface. The camera perspective shifts from close-up of the brushwork to a wide overhead shot of the artistic materials.

A hand holding a paintbrush is moving across the canvas, applying paint; the brush is the discrete moving object.

The background (canvas) is static and fixed; no shifting background or fluid/environmental motion (fire, water, smoke, wind) observed.


Several sailboats with gray sails navigate around a red buoy in the water; sailors adjust their positions as the vessels move from left to right, maintaining a steady course past the buoy. The camera follows the boats with a slight pan, capturing their motion against the open sea.

Sailboats are the discrete solid objects moving through the water, propelled by wind on their sails, with clear bounding box tracking across frames.

The background features a static horizon line, distant land, and sky with minimal shifting. The water shows gentle waves, but the dominant motion is not driven by fluid dynamics as the primary subject.


RAW CAPTION: Okay, I need to create a concise chronological paragraph for this video. Let's see. The video shows a group of people dancing in what looks like an indoor space. First, I should focus on the main subjects, which are the dancers. There are a lot of them, so I need to mention the number and their appearance.

The description says to focus on motion and behavior in order. The first frame shows a group moving, maybe a line or a formation. They're all dancing, so their main action is moving in sync. The appearance: some are wearing cowboy hats, like white ones, others maybe black. There's an American flag in the background, but the rule says minimal background unless essential. Maybe just mention the setting briefly.

Chronologically, the video starts with people dancing. They're moving in a line, perhaps a line dance. The camera is probably panning left, following the movement. The first few frames show different angles as the camera moves. The people are in various positions—some in front, others behind. Need to mention spatial relationships if relevant.

Let me check the rules again. Avoid text recognition, so no mention of specific words on shirts. Number of people: it's a group, so "a large group" or "many people." Their appearance: cowboy hats (white and black), some in uniforms maybe? The video shows a mix of men and women, some in dresses, some in jeans.

Camera movement: the examples given in the problem have a pan left, slight shake. The user's example says "pan left" so maybe here it's panning left as well. The caption should end with camera perspective and movement.

So putting it all together: A large group of people wearing cowboy hats and casual attire dance in unison across a room. The dancers, including men and women, move in synchronized steps, some leading while others follow, with individuals positioned in front or behind one another. The camera pans left, following the group's motion, capturing their energetic movements in a spacious indoor setting with minimal background details.

Wait, need to check if "cowboy hats" are mentioned. The first frame shows white cowboy hats. Maybe "some wearing white cowboy hats" but the rule says briefly describe appearance. The user example says "color, size, orientation," but since it's a group, maybe "a large group of people in cowboy hats and casual clothing."

Wait, the rules say "briefly describe their appearance and number (color, size, orientation)." So number: large group. Color: some white cowboy hats, others black hats? The initial frames show a white cowboy hat and a black one. So maybe "a large group of people, some wearing white and black cowboy hats, dance in formation."

Then motion: moving in sync, steps, etc. Spatial: some in front, others behind. Camera: pans left, following the group.

Let me structure it:

In a spacious indoor room, a large group of people, including men and women wearing cowboy hats and casual clothing, perform synchronized line dancing. They move in unison across the space, with individuals positioned in front or behind one another. The camera pans left, tracking the group's progression while capturing their energetic steps and coordinated movements. Background elements are minimal, focusing on the dancers' motion.

Wait, but the video starts with the group moving, then the camera follows their movement. The first part shows a group moving left, then the camera pans left. So the chronological order would be the group moving from right to left as the camera pans left. So the caption should mention that the camera is panning left following the group.

Need to make sure it's chronological: starting with the group dancing, then the camera movement. The caption should describe the motion as it happens.

Another point: the video transitions through frames showing different parts of the group. So the group is moving across the room, the camera following them, shifting perspective as the group moves.

So maybe:

A large group of people wearing cowboy hats and casual attire dance in a synchronized line formation. They move in unison across the room, with some dancers positioned in front while others follow behind. The camera pans left, tracking the group's progression and capturing their coordinated steps and energetic movements.

Check for all rules: chronological, appearance (cowboy hats, casual), spatial (front/back), camera movement (pan left), minimal background. Exclude text recognition. Yes.

Wait, the rule says "briefly describe their appearance and number (color, size, orientation)." So mention the number (large group), colors (white and black cowboy hats), but maybe not too detailed. Since the problem says "color, size, orientation" but for people, maybe "cowboy hats (white and black)".

Wait, the user example in the problem statement for a different video might have something like "a group of people wearing white cowboy hats, moving in a line." So perhaps

Numerous people (dancers) are moving in coordinated patterns (e.g., step-based dancing) as discrete solid objects. Their locomotion is visible and trackable with bounding boxes.

The background walls, floor, and static elements (e.g., American flag, red curtains) remain stationary with no uniform shifting. No fluid environmental motion (fire, water, smoke, wind) is present.


An athlete in red shorts and a dark top stands within a circular throwing area, holding a hammer. He begins spinning in place, rotating multiple times to build momentum while maintaining a wide stance. After completing the rotation, he releases the hammer. The background includes a green field and netting enclosing the area. The camera maintains a static perspective throughout the sequence.

A person (athlete) performs a hammer throw: rotating their body, swinging the hammer in circular motion, and releasing it. The hammer and athlete are solid objects moving due to explicit physical forces (locomotion, rotational momentum).

The background elements (green field, red track, white markings, blue fence) remain stationary across frames with no uniform shifting or fluid motion (e.g., no fire, water, wind).


A woman in a black shirt and camouflage pants performs a single-leg push-up in a gym. Starting in a plank position with hands on the floor, she lifts her right leg upward, maintaining a straight body line, then lowers it back down, repeating the motion. Other gym-goers and equipment are visible in the background. The camera remains stationary, capturing her from a front-facing angle.

A woman performs push-ups, moving her arms and legs in a controlled, discrete manner while maintaining contact with the ground.

Background elements (e.g., gym equipment, 'FITNESS' signage) remain static and show no uniform shifting; no fire, water, smoke, or wind motion observed.


A boy in a checkered shirt jumps inside a teal and purple inflatable bounce house, while a girl in a white dress stands near the entrance and a child in blue overalls sits on the floor. The boy descends, the girl jumps, and another child in a gray shirt enters from the side. The girl continues jumping as children move around the structure, with the camera remaining stationary and facing the bounce house directly.

Children are actively jumping, running, and interacting within the inflatable bounce house. Their movements are discrete, solid-object locomotion (e.g., jumping, shifting positions) without fluid dynamics.

The background includes static elements like the inflatable structure's printed characters, fence, and distant buildings. No fluid motion (fire, water, smoke) or wind-driven swaying is visible. Background elements do not shift uniformly, indicating no significant ambient environmental motion.


A person wearing a vibrant blue, green, and orange floral Hawaiian shirt plays a light-colored ukulele; close-up on hands strumming the instrument, camera pans up to reveal a bald man holding the ukulele, then pulls back to show the seated figure outdoors on grass with plants in the background. Camera transitions from tight focus on hands to wider shot of the individual in the garden.

The person's hands and the ukulele are moving due to the physical act of playing the instrument (strumming and fretting).

Background shows minimal motion (grass and plants swaying slightly), but no dominant fire, water, smoke, or wind effects. Ambient motion is negligible.


A pair of hands holds a small blue and white wool piece over an orange sponge, using a needle to repeatedly pierce and compact the wool. In the background, a blue mermaid-shaped object lies to the left, and a gray fish-shaped object rests to the right. The camera remains stationary in a top-down view, focusing on the hands' precise motions. The hands continue the felting process, manipulating the needle through the wool while keeping the object stable on the sponge.

Hands manipulating a blue bead on a wooden block; motion involves controlled rotation and pressure application by the hands (discrete solid objects in interaction).

No shifting background; no fluid or environmental motion observed. Static background elements (dark blue curved object, gray circular object) remain fixed across frames.


RAW CAPTION: Got it, let's see. The video shows two men working on a cabinet. First, one guy in a green shirt with "SUNBURST SHUTTERS 47" is reaching up to a cabinet. The other guy is in a gray shirt, orange cap, holding a pole. They're both interacting with the cabinet. The green-shirted guy has a tool belt with various tools. The camera seems to be stationary, maybe a bit shaky. Let's structure it chronologically.

Start with the first frame: two men, one in green shirt (number 47) and another in gray with orange cap, near wooden cabinets. The green-shirted man is reaching up, the other is holding a red pole. Then they both move, the green guy adjusts the cabinet, the other guy holds the pole. The green shirt guy has a tool belt. The background is a kitchen or similar with cabinets and some items. Camera is steady but maybe a slight shake.

Wait, need to follow the rules. Focus on motion and behavior in order. So:

- At the beginning, two men are positioned near a wooden cabinet. The man in the green shirt (with visible number 47) reaches up towards the cabinet’s upper section. The man in the gray shirt, wearing an orange cap, holds a long red pole-like tool. They both adjust the cabinet; the green-shirted man steps slightly to the side while the other uses the pole. The green-shirted man has a tool belt with multiple tools visible on his waist. The camera remains stationary with minimal movement, capturing the two men’s coordinated actions around the cabinet.

Check the rules: no text recognition (so don't mention the "SUNBURST SHUTTERS" text, just the number 47 as part of appearance). Wait, the problem says "exclude text recognition"—so if the shirt has text, we shouldn't mention it. Oh, the user's instruction: "Exclude text recognition, named characters, or stylistic analysis." So the green shirt has "SUNBURST SHUTTERS 47"—we can mention the number 47, but not the text. Wait, the rules say: "b) Briefly describe their appearance and number (color, size, orientation).". So "number 47" is part of appearance. But text recognition is excluded? Wait, the rule says "Exclude text recognition, named characters, or stylistic analysis." So if the text is "SUNBURST SHUTTERS", that's text recognition, so we can't mention that. But the number 47 is a number, so it's okay.

So correct: the green shirt has the number 47, so we say "man in green shirt with number 47".

Let's rephrase:

Two men stand near a wooden cabinet; the man in the green shirt (number 47) raises his hands toward the cabinet’s upper section while the man in the gray shirt, wearing an orange cap, holds a long red pole. The green-shirted man steps back, adjusting his position as he works with the cabinet, while the gray-shirted man continues to manipulate the pole. Both are positioned close to the cabinet, with the green-shirted man’s tool belt visible. The camera remains stationary, capturing their coordinated movements around the cabinet.

Wait, but need to be concise and chronological. Let's check the timestamps:

[0.0] First frame: green-shirted man reaching up, gray-shirted man (orange cap) holding pole.

[1.0] They're adjusting, the green guy steps up, gray guy holds pole.

[2.0] Green guy still on the cabinet, gray guy moving the pole.

[3.0] Green guy steps back, gray guy adjusts the pole.

[4.0] Green guy turns, gray guy holds pole.

So the sequence is: the green-shirted man reaches up to the cabinet, the gray-shirted man uses a pole to adjust the cabinet. They work together, with the green-shirted man moving around to access the cabinet. The camera is steady.

Putting it all together:

Two men collaborate near a wooden cabinet; the man in the green shirt (number 47) raises his arms to adjust the cabinet’s upper section, while the man in the gray shirt, wearing an orange cap, holds a red pole-like tool. As the sequence progresses, the green-shirted man shifts his position and steps back, continuing to work with the cabinet, while the gray-shirted man maintains his grip on the pole. Both are closely positioned by the cabinet, with the green-shirted man’s tool belt visible. The camera remains stationary throughout the actions.

Check for rules:

a) Motion in chronological order: yes, describes the actions step by step.

b) Appearance and number: green shirt number 47, gray

Two individuals interacting with a cabinet: one manually opens the cabinet door while the other uses a tool, showing discrete movement and physical interaction with the cabinet and tools.

No shifting background elements (walls, cabinets) or fluid/environmental motion (fire, water, smoke, wind) observed.


A person with long dark hair and a black top uses a black hairdryer and blue brush to style another individual's long dark hair; the stylist moves the hairdryer across the hair, then employs the brush to smooth sections before stepping back. The camera remains stationary with slight shake against a dark wall background.

A person is holding a hair dryer and moving it to style their hair. The person's head and arms are in motion, indicating deliberate physical movement.

The background (dark blue wall and green ball) is static. No environmental fluids (fire, water, smoke) or wind are present. The background does not shift uniformly, so not camera motion.


A person in dark clothing holds a red megaphone, approaching two seated individuals. The first seated person (wearing a black shirt) reacts by leaning back and covering their ears as the megaphone is directed toward them. The second seated person (in a light top and jeans) also covers their ears. The camera remains handheld with slight movement throughout.

Two seated individuals react to a megaphone by covering ears and shifting positions; the person holding the megaphone moves slightly while speaking. All motion is attributed to human locomotion and physical response.

The static background elements (walls, ceiling lights) show no uniform shifting or environmental motion (fire, water, wind, smoke). Background remains consistent across frames.


A person’s hand guides a metallic carpet tucking tool along the edge of a beige, textured carpet, pressing it firmly against a baseboard adjacent to a light wooden floor. The individual kneels on the carpet, moving the tool steadily from left to right to secure the carpet’s edge. The camera maintains a top-down perspective, closely following the hand and tool’s motion.

A person's hand and a cloth are moving horizontally along the floor, indicating active physical manipulation of the object.

The background elements (door frame, floor tiles) show minimal uniform shifting; no fire, water, or wind-driven motion present.


Four individuals in a space station interior interact in microgravity. A person in a blue jumpsuit begins upside down, hands raised, then rotates to sit beside a seated person in a black shirt. The blue-jumpsuit individual holds a microphone toward the seated person. A person in a blue-and-gold striped polo shirt and another in a red sweater move behind, gesturing. The camera remains stationary, capturing the scene from a fixed angle.

Briefly describe what discrete, solid objects are moving.

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


A person in a black shirt holds a dark harmonica with silver details to their mouth, playing; then lowers the harmonica, gestures with their right hand; subsequently raises the harmonica to display it before bringing it back to their mouth. The camera remains static, focused on the individual against a softly lit background featuring a fireplace and decorative items.

A person (man) is playing a clarinet, with movements of hands and lips due to instrument playing.

No shifting backgrounds or fluid/environmental motion observed. Background elements (painting, shelf, lamp) are stationary.


A large bouquet of red and light pink roses is positioned in the frame. Two light-skinned hands enter from the left and right sides, adjusting and rearranging the roses within the bouquet. The hands move the roses, shifting their positions while interacting with the flowers. The camera remains in a static close-up position throughout.

A person's hands are moving to adjust and arrange roses (discrete, solid objects) within a floral arrangement.

The background (wall and stationary elements) shows no significant shifting or environmental fluid motion; no fire, water, or wind effects are present.


A man in a white shirt and dark jeans moves in a circular path around a large black animal lying on sandy ground inside an enclosed arena. The man adjusts his position while the animal remains stationary, with spectators visible behind railings. The camera maintains a fixed perspective throughout the sequence.

The man (white shirt, dark pants) moves by walking and interacting with the lion; the lion (large cat) moves by standing, lying down, and reacting to the man's actions, both exhibiting solid object motion due to physical forces.

Background elements (railings, 'CIRCO' sign, spectators) show no uniform shifting or fluid motion; environment is dry with no fire, water, smoke, or significant wind effects.


A large crowd of people, wearing diverse attire in colors like black, purple, and green, dance closely together on a blue floor, moving in coordinated swaying and rotating motions. Their positions shift continuously as they interact, with some holding hands while others move independently. The camera maintains a wide perspective, slightly panning to follow the crowd’s flow.

A large crowd of people are engaged in dancing, moving in a coordinated manner due to physical locomotion and social interaction, forming distinct discrete object movements.

The background elements (bleachers, walls, stage) are static and show no uniform shifting. No ambient environmental motion (fire, water, smoke, wind) is present.


RAW CAPTION: Got it, let's break this down. The video starts with close-up hands tearing a pastry. First, the hands are shown pulling apart the food. There are two hands: one with a silver ring and another with a gold ring. The pastry is golden brown, flaky, with some dark filling inside. Then, the scene shifts to an outdoor setting where a woman in a black shirt and sunglasses is standing near a food truck. The background has people and a tree, but I need to keep background minimal. The transition is from close-up to a wider shot. Let's make sure the caption is chronological: first the hands tearing the pastry, then the woman at the food truck. Describe the motion: hands pulling the pastry apart, then the scene changes to the woman. Mention spatial relationships: the hands are in front of the pastry, then the woman is in front of the food truck. Camera movement: starts with close-up, then cuts to a wider shot (maybe pan or cut, but the rule says "camera perspective and movement" so note the shift from close-up to a wider view). Check rules: no text, no names. Keep it concise. Let's draft:

Two hands, one with a silver ring and another with a gold ring, tear apart a golden-brown, flaky pastry revealing a dark filling. The hands manipulate the pastry, pulling it into pieces over a white dish with a yellow rim. The scene transitions to a wider shot showing a woman standing in front of a red food truck, with people and a tree visible in the background.

Wait, need to check if the background is essential. The problem says "minimal unless essential". The transition is key, so the scene change is part of chronology. Let me structure it:

Close-up of two hands tearing a golden-brown pastry with visible dark filling; one hand wears a silver ring with intricate design, the other a gold ring. The hands pull apart the flaky layers, revealing the interior. The scene then shifts to a wider view of a woman standing near a food truck in an outdoor setting, with a few people and a tree in the background.

Wait, the video starts with hands, then transitions to the woman. Let's make sure the order is correct. The first 5 seconds are hands, then the 6th frame shows the woman. So the chronological sequence is: hands tearing pastry (first part) then the woman. Need to describe the motion of hands first.

So: Two hands, one adorned with a silver ring featuring an intricate design and the other with a gold ring, grasp and pull apart a golden-brown, flaky pastry filled with dark ingredients. The hands manipulate the pastry, tearing it into pieces over a white dish with a yellow rim. The scene then cuts to a wider shot of a woman standing in front of a red food truck, with indistinct figures and a tree visible in the background.

Check rules: exclude named characters (woman is described as "a woman", not name), text recognition (no text in the video mentioned), spatial: hands in front of pastry, woman in front of food truck. Camera perspective: starts close-up, then cuts to wider shot. Mention camera movement: "cuts to" or "transitions to". The rule says "conclude with camera perspective and movement" so at the end: starts with close-up, then shifts to wider view.

Let me check the example format. The user says "conclude with the camera perspective and movement (e.g., top-down, pan left, slight shake)".

So the caption should end with how the camera moves. The transition is from close-up to a wider shot (so maybe "cut to wider view").

Putting it all together:

Two hands, one with a silver ring and the other with a gold ring, tear a golden-brown, flaky pastry filled with dark ingredients. The hands pull apart the pastry, revealing layers, over a white dish with a yellow rim. The scene then transitions to a wider shot showing a woman standing in front of a red food truck, with people and a tree in the background. The camera starts with a close-up and shifts to a wider perspective.

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

Two hands with a silver and gold ring tear apart a golden-brown, flaky pastry with a dark filling, pulling it into pieces over a white dish with a yellow rim. The scene then cuts to a wider view of a woman standing in front of a red food truck, with people and a tree in the background. The camera transitions from close-up to a wider perspective.

Check if "women" is correct. The description says "a woman". Let's use "a woman".

Two hands, one adorned with a silver ring and the other with a gold ring, pull apart a golden-brown, flaky pastry revealing a dark filling. The hands manipulate the pastry over a white

Hands tearing food (discrete objects) in the first scene; stationary person in the second scene.

No shifting background elements (static bowl in first scene, static environment in second scene). No fluid or wind motion observed.


A person in dark shorts and a black shirt walks from left to right across a grassy field, then stops; a second person in dark clothing remains stationary in the background. The camera maintains a low, stationary perspective.

A person in the foreground is walking (left to right), moving due to locomotion. A second person in the background is stationary.

The background (trees, fence) is stationary. No fluid or environmental motion (fire, water, smoke, wind) is visible. The ground and trees do not shift uniformly, indicating no camera-induced motion.


A baby in a blue shirt crawls toward a white door, rises to a seated position while gripping the doorframe, and turns to face the camera. The baby remains seated, with a beige wall and black dresser visible in the background. The camera is stationary.

A baby (discrete solid object) moves by crawling and supporting itself on the door, demonstrating intentional locomotion with clear bounding box tracking.

The background (wall, door, furniture) shows no shifting or fluid motion; no fire, water, smoke, or wind is present. Static elements remain fixed throughout.


A baby in a white patterned onesie lies on a colorful play mat, initially positioned on their stomach. The baby rolls onto their back, moving their arms and legs, while the play mat's green and red sections are visible beneath them. The background includes a carpeted floor with scattered toys. The camera maintains a stationary top-down perspective throughout.

The baby, as a discrete solid object, moves by kicking legs and moving arms due to muscle contractions, with clear bounding box tracking.

The background (carpeted floor and distant furniture) remains static with no uniform shifting or environmental fluid motion (fire, water, smoke, wind).


A person in a blue shirt arranges playing cards with hands in a close-up shot. The camera pulls back to reveal a pyramid of cards on a table, then shifts to show two individuals seated at the table; one gestures with their right hand while the other faces forward. The background features tiled walls. The camera perspective moves from close-up to wider shots, capturing the table and seated subjects.

Hands manipulating card structures (collapsing them) and two individuals at the table moving hands/arms.

No shifting background elements (tile wall remains static), no fire, water, or wind motion observed.


A young boy in a white shirt leans forward, his head moving downward toward a blue and yellow object on a surface. He shifts his head position slightly, appearing to interact with the object. The background includes a bathtub with indistinct items. The camera maintains a close-up perspective with minor shaking throughout.

The child (a solid, distinct object) exhibits head and body movements, including tilting, lifting, and shifting position while remaining seated.

No shifting background or fluid/environmental motion detected; background elements (white surface, blue object) remain static and unchanging throughout the frames.


A hand holding a yellow pencil points to a cell in a KenKen puzzle grid, then writes a number within it. The hand subsequently shifts to an adjacent cell and writes another number. The camera maintains a stationary top-down perspective throughout the sequence.

A hand holding a pencil moves across the puzzle grid, making discrete writing motions to fill in numbers, indicating active physical interaction with the puzzle.

The background consists of a static printed puzzle page with no shifting elements, fluid motion, or environmental effects (fire, water, wind).


A person wearing a blue vest over a white shirt stands at the edge of a pool next to blue and red coolers, facing a group of children swimming in the water. The person bends forward, opening the coolers, while the children splash and move in the pool. The camera follows the person’s movement with a slight pan.

People swimming in the water are the primary discrete objects, moving via locomotion (swimming) and creating splashes. The person on the shore interacts with coolers, showing slight movement.

The water shows minor ambient movement (ripples/splashes), but the dominant motion is not fire, smoke, or large-scale environmental phenomena. The static background (beach, distant structures) remains relatively stable without uniform shifting.


A boy in a black-and-white striped shirt and blue jeans sits to the left of a girl in a green hoodie at a desk. The boy extends his right hand to touch the girl’s hair, then retracts it, followed by adjusting his own hair while the girl remains seated, facing downward. The camera remains static with minimal shake throughout, capturing the interaction against a plain wall background.

Two people are visible: one in a black/white shirt moving arms and adjusting posture, and another in a green shirt writing. Their movements are discrete, voluntary actions without environmental interaction.

The wall in the background remains static across frames with no signs of shifting or environmental fluid motion (fire, water, smoke, wind).


A black and white dog with a white patch on its face lies curled on a dark surface. A hand holding a grooming tool enters the frame from the top right, moving toward the dog's head as it continues grooming. The dog remains still, facing forward. The camera maintains a static top-down perspective throughout.

A human hand (discrete object) moves to pet a cat, causing minor displacements in the cat's head, ears, and body. The cat's reactions are direct physical responses to the hand's motion.

The background (dark surface, small metallic object, and blurred electronics) is static with no shifting or fluid motion (e.g., no fire, water, smoke, or wind effects). Background elements remain consistent across frames.


A dark liquid from a glass is poured into a metallic shaker. The shaker is shaken briefly with ice. The mixture is then double-strained into a martini glass. The scene is shot from a top-down perspective, focusing on the pouring and shaking actions against a wooden surface background.

Discrete objects: person's hands moving the glass and shaker, the metal shaker being shaken (with ice inside), and the ice cubes inside the shaker. The wine is poured and then shaken, but the liquid motion is a result of the shaker's motion.

The background (wooden table and wall) is static; no shifting or dominant ambient motion (fire, water, wind). The liquid motion (wine) is contained and controlled by the shaker's shaking, not ambient.


A person holds a smartphone to record a scene in a classroom. Two individuals interact: one in a dark jacket bends over toward another in a white top, then stands upright, and subsequently bends down again. The phone holder remains stationary on the left, capturing the interaction from a fixed perspective. Background includes blue chairs and a bulletin board, but focus on the actions.

Two people are moving: one seated at a desk (white shirt) and one standing (dark jacket). The standing person bends over, stands upright, and repeats bending motions while interacting with the seated individual. The phone holder on the left is stationary. All motions are discrete and solid, driven by human locomotion and interaction.

The background includes a static bulletin board with papers and ceiling elements. No shifting background or fluid/environmental motion (fire, water, wind) is observed. The scene remains stable with consistent spatial relationships between background features.


A man in a yellow vest works at a yellow construction machine on a dirt site, with a sand pile behind him. He moves his arms, gesturing and adjusting materials near the machine, then the scene darkens. The camera remains stationary throughout the sequence.

The person in yellow clothing is moving (leaning, turning, stepping), and the wheelbarrow is being manipulated by the person. These are discrete solid objects with motion driven by human locomotion and interaction.

Background elements (mountains, trees, sky) show no uniform shifting or fluid/environmental motion (no fire, water, smoke, or significant wind effects observed).


RAW CAPTION: Got it, let's break this down. The video shows a track and field event, probably hammer throw. First, the main subject is an athlete in a green shirt and black pants. Wait, the first frame has a person in red? Wait no, looking at the frames: frame 0 has a person in maroon, then frame 1-5 shows a person in green. Let's check the sequence.

Frame 0: Athlete in maroon shirt, dark pants, standing on a circular platform (throwing circle), holding a hammer (or maybe a discus? Wait, the net is for hammer throw, so likely hammer). Then frame 1: same athlete, starts spinning. Frame 2: spinning, building momentum. Frame 3: continues spinning, then frame 4: maybe releasing? Wait, the sequence: the athlete is in the throwing circle, spins around, then releases. The background has a green field, track, and a netted area (safety net). There's a small inset in some frames showing the athlete from a different angle, but the main focus is the main athlete.

So chronological order: the athlete (green shirt, black pants, large in size) starts in the throwing circle, spins around multiple times, then releases the hammer. The camera is fixed, watching from the side (since we see the athlete's movement in the circle, and the net is visible). Background is a track field with grass, trees, and a few people in the distance. The inset might be a split screen, but the main view is the athlete's motion.

Need to describe appearance: green shirt, black pants. Number: one main athlete, and maybe the inset is another, but the main subject is one. Spatial: athlete is on a circular platform, surrounded by a net. Moves in a circular motion, spinning, then releasing.

Camera perspective: probably a side view, maybe slightly elevated? The description should mention camera is stationary or fixed, as the frames don't show movement. Background minimal: track, grass, net.

So putting it together:

A single athlete wearing a green shirt and black pants is seen in a throwing circle on a track field, surrounded by a safety net. The athlete begins spinning in place, rotating repeatedly while holding a heavy implement, then releases it. The camera captures the motion from a fixed side perspective, with the background featuring a grassy field and distant trees. The inset view shows a smaller copy of the athlete's movements but is not the main focus.

Wait, but the rules say "conclude with camera perspective and movement". So camera is fixed, maybe slight shake? But the video frames look steady. The output should be concise.

Let me check the rules again:

a) Motion and behavior chronologically: athlete spins, then releases.

b) Appearance: green shirt, black pants, one person.

c) Spatial: on the circle, net around.

d) Camera: fixed, side view.

e) Background minimal: grass, trees, track.

f) Exclude text, names, etc.

So draft:

A single athlete in a green shirt and black pants spins in a circular throwing area surrounded by a green safety net, then releases the implement. The camera remains fixed, observing the athlete's motion from a side perspective with a grassy field and distant trees visible in the background.

Wait, the first frame has a different outfit (maroon), but the next frames are green. Wait, maybe it's the same person, just different frames. Wait, the problem says "main subjects", so probably the same person. Let's check the frames: the first frame (0.0s) shows a person in maroon, then frame 1.0s to 5.0s shows green. Maybe it's a different athlete? Or maybe the person changes. Wait, the task is to focus on the motion of the main subjects. The key is the action: spinning and throwing. So regardless of color change, the main action is the athlete spinning, building momentum, then releasing.

Wait, maybe it's the same person, the color is different because of lighting? Or maybe the video cuts between different athletes. But the problem says "main subjects", so focus on the main action. Let's see: in the frames provided, the athlete in green is spinning, then moving to release. So the caption should focus on that.

Also, the inset in the frame (like a small copy) is present. Wait, the frames show a split screen sometimes: the main view and a smaller view of the same athlete. So the main subject is the athlete in the main screen, and the inset is secondary.

So the main subject is one person (green shirt, black pants) in the main frame. They are spinning in the throwing circle, then releasing. The inset is a smaller version of the same action, but the main description should focus

Pitcher (green shirt, black pants) performing a pitching motion (winding up, throwing). Catcher (green shirt) is stationary.

Background elements (fence, trees, building) are stationary. No fire, water, smoke, or wind motion observed.


RAW CAPTION: Got it, let's break this down. First, the video shows a woman in a gym doing diagonal walking lunges. The main subject is her. Let's check the rules.

Starting with the motion: she's performing diagonal walking lunges. She's wearing a black jacket, light blue top, gray shorts, white shoes. Then she moves back and forth, walking in a pattern. The camera is stationary, I think. Background has gym equipment: treadmills, weights, a TV. But we need to keep background minimal.

Chronological order: first she's in the starting position, then walks forward, then backward, etc. Wait, the video frames show her doing the exercise. Let's see the sequence. Frame 0: she's in the middle of a lunge. Frame 1: she's moving forward. Frame 2: she's walking away, then frame 3: moving back. Wait, the description says [0.3] she's doing diagonal walking lunges, then she walks away, then comes back? Wait, the frames: the first frame has her in position, then she walks forward (frame 1), then frame 2 she's walking away from the camera, frame 3 she's moving back? Wait, the video is a short clip.

Wait, the video shows a woman performing diagonal walking lunges. She starts in a lunge position, then steps forward, then back, repeating. Let's outline the motion.

First, she's in the gym, performing the exercise. She's wearing a black jacket, blue top, gray shorts, white sneakers. Her hair is tied up. She moves in diagonal walking lunges, stepping forward with one leg and back with the other, shifting weight.

Spatial relationships: she's in the center of the frame initially, then walks away from the camera (toward the door), then comes back.

Camera perspective: stationary, eye-level, facing the woman.

Background: gym equipment like treadmills, weights, a TV on the wall. But minimal, so maybe just "gym setting with equipment".

Now, put it all together in chronological order.

Start: woman in gym, performing diagonal walking lunges (steps forward, then backward, repeating). She wears black jacket, light blue top, gray shorts, white shoes. Moves in a diagonal pattern, stepping forward and back.

Check the rules: a) motion in chronological order. b) appearance: black jacket, blue top, gray shorts, white shoes. c) spatial: moves forward (away from camera), then back (toward camera). d) camera: stationary. e) background minimal. f) no text, no names.

So the caption should describe her actions step by step.

Let me draft:

A woman in a black jacket, light blue top, gray shorts, and white shoes performs diagonal walking lunges in a gym. She steps forward with her right leg while lowering her body, then shifts weight back to her left leg, repeating the motion. She walks away from the camera toward the back of the gym, then returns toward the camera, maintaining the exercise pattern. The camera remains stationary at eye level, capturing her movement against a backdrop of gym equipment.

Wait, but need to make it concise. Let's see the example.

Wait, the sample output should be concise. Let's check the frames: first she's doing the lunge, then walks forward (frame 1), then frame 2 she's walking away, frame 3 she's walking back. So the chronological sequence is: she begins the exercise (lunge), steps forward, then walks away, then turns back.

Wait, the video description says:

[0.0] she's in the gym, diagonal walking lunges text. Then [1.4] she moves forward (maybe completing the lunge), then [2.5] she walks away from the camera, then [3.6] she walks back toward the camera.

Wait, let's parse the frames:

Frame 0.0: "Diagonal Walking Lunges" text, woman in position, doing lunge (maybe right leg forward, body lowered).

Frame 1.4: she steps forward (left leg maybe), then moves away from camera.

Frame 2.5: walking away from camera toward door.

Frame 3.6: walking back toward camera.

So chronological order: she starts the exercise (lunge), then steps forward (to the left, maybe), then walks away from the camera, then returns toward the camera.

So the caption should describe her performing diagonal walking lunges (stepping forward/backward in diagonal), then moving away, then back.

Let's rephrase:

A woman wearing a black jacket, light blue top, gray shorts, and white sneakers performs diagonal walking lunges in a gym, stepping forward and back while maintaining balance. She walks away from the camera

The woman performs diagonal walking lunges, moving her legs and torso in a controlled, directional pattern. Her locomotion involves discrete displacement with clear bounding box tracking.

Static gym environment with fixed equipment (weights, benches) and a television; no fire, water, smoke, or wind observed. Background elements remain stationary without uniform shifts.


A young boy wearing a red and black striped shirt and gray pants sits on a beige carpet, holding a yellow toy and manipulating it with both hands. To his right, a baby in a brown outfit sits on the carpet, engaged with a toy. The boy shifts his gaze slightly upward while continuing to handle the yellow toy. The camera remains stationary with minimal movement, capturing the scene from a top-down perspective.

A child in a striped shirt is manipulating a yellow object (likely a toy or snack) with minor hand movements. An infant in the background is also present but relatively still.

Background elements (wall, carpet) are static with no shifting or fluid motion. No fire, water, or wind visible.
