A person wearing blue shorts and a black shirt drags a large dark alligator across floating tires in murky water, stepping onto the tires to move it forward. The person bends to adjust the alligator’s position on the muddy shore. The camera follows the action with slight shifts, capturing the alligator’s motion through the tires and onto land.

The person (wearing blue shorts) is moving across the scene, stepping on tires and interacting with the alligator. The alligator is actively moving through the water, creating splashes and displacing the water. Both are distinct, solid objects exhibiting motion due to locomotion and interaction.

The background (sand, fence, and distant structures) remains static with no uniform shifting, indicating no significant camera-induced motion. Water shows minor ripples and splashes caused by the discrete objects (person and alligator), but the water itself is not the dominant motion (no flowing, crashing waves, or wind-driven effects).


A person in a camouflage jacket and blue gloves moves a large black tire in front of a red industrial structure. They then lift a yellow rectangular metal mesh panel and position it against the tire, aligning it with the structure. The camera maintains a close-up perspective with slight movement throughout the sequence.

A person in camouflage clothing (wearing blue gloves) manipulates a large black tire and a yellow mesh cage, with a second individual assisting in moving the cage. Both subjects exhibit controlled physical movements involving direct interaction with solid objects.

Static background elements (orange vehicle, structural components) show no uniform shifting or fluid motion; no fire, water, or smoke present.


A man with extensive tattoos on his arms and glasses works on a woman’s hand; the woman, with long dark hair and light clothing, holds her hand steady as the man manipulates a small tool. The camera maintains a close-up view of their hands, with slight motion, capturing the focused interaction, set against a minimal background.

Two discrete solid objects (people) are moving: the tattoo artist's hands manipulating a tattoo machine, and the woman's arm being worked on during tattooing.

The background (wall) is static with no fluid elements (fire, water, smoke, wind) or uniform shifting, ruling out ambient environmental motion.


A person wearing a dark sleeveless top and dark shorts stands within a circular throwing area enclosed by a green net. They initiate a clockwise spinning motion, rotating their body while preparing to release an implement. The background includes a grassy field with distant trees and figures, but the focus remains on the person’s rotational movement. The camera maintains a static perspective throughout the sequence.

A person performs a discus throw: spinning in place, then releasing the discus. The motion is locomotion-driven (spinning/throwing) with clear physical force application.

Background elements (trees, net, distant structures) show no uniform shifting. No significant fluid/environmental motion (fire, water, smoke) or wind-driven swaying observed.


RAW CAPTION: Okay, I need to generate a concise chronological paragraph for this video based on the provided frames. Let me go through each frame step by step.

First frame shows a screen with different sizes of shooting pads. The main subjects here are the text listing the sizes, but according to the rules, I should exclude text recognition. So maybe skip that part. The next frame is an ice rink with a person using a hockey stick to shoot at a net. Then it transitions to a backyard scene with another person shooting at a net. Then there's a close-up of someone with a roller skate on a pad. Wait, the user says to focus on motion and behavior, so the main actions here are shooting hockey pucks at nets in different locations.

Wait, the second frame (1.4 seconds) shows a person on ice, then the third frame (2.5s) is the same person but maybe on the ice, but the next one is a backyard. Wait, the frames are:

[0.0] starts with the product display.

[1.4] ice rink, person shooting at net.

[2.5] person on ice? Wait no, the second frame is a person on ice, then next frame (2.5s) is same person? Wait the given timestamps: the first frame is [0.0], then [1.4], [2.5], [3.6], [4.7]. Wait the user provided the video in segments.

Wait, looking at the user's input, the frames are:

- Frame 0: Display of product sizes (but exclude text)
- Frame 1.4: Person on ice rink shooting at a net.
- Frame 2.5: Person on ice (but maybe different angle?) or perhaps outdoors? Wait no, the next frame is [2.5] shows a person in backyard shooting at a net.
- Frame 3.6: Person in backyard, same action.
- Frame 4.7: Close-up of someone with roller skates and a puck on a pad.

Wait, the user's description says:

"Frame 0: text showing sizes. Then frame 1.4: ice rink with red net. Frame 2.5: person in black shirt and blue shorts on backyard with net. Frame 3.6: same as above. Frame 4.7: person with roller skates on pad."

Wait, the actual frames are:

<0.3> shows product display.

<1.4> shows ice rink with red net.

<2.5> shows person on ice (but maybe same as 1.4?), but the next frame <3.6> shows outdoor backyard. Wait, the user's description says:

<0.3> [text]

<1.4> ice rink, person shooting.

<2.5> outdoor backyard, person shooting.

<3.6> same outdoor scene.

<4.7> close-up of person with roller skate on pad.

Wait, the problem is the video transitions from ice rink to backyard to another outdoor setting, then to the roller skate scene.

The task is to describe the motion chronologically. So the sequence is:

1. Product display (but skip text, so maybe mention the product is shown but focus on action later).

2. Then a person on an ice rink shooting a puck at a net.

3. Then the same person (or another) in a backyard setting, shooting at a net.

4. Then another outdoor scene, perhaps the same person continuing.

5. Then a close-up of someone using a roller skate on a pad.

But the rules say: focus on motion and behavior of main subjects, chronological order.

First, the initial frame (0.0) shows the product, but since we can't mention text, perhaps move to the next actions. So the video starts with the product display (ignore text), then cuts to ice rink, then to backyard.

The main subjects are people shooting hockey pucks. The first action is on ice rink: person (gender maybe male, wearing blue helmet, black and red shirt) shooting. Then next scene: another person (black shirt, blue shorts, blue helmet) in backyard, shooting. Then maybe another shot of the same person. Then a close-up of someone with roller skates on the pad.

Wait, the frames are:

1.4: ice rink, red net, person shooting.

2.5: same person? Or different? The next frame 2.5 is described as "a person in black shirt and blue shorts on backyard" so maybe a different person.

Wait the user provided:

<1.4> shows ice rink with red net.

<2.5> shows person in black shirt, blue shorts, on concrete with net.

<3.6

Discrete objects include the hockey puck (red, moving due to collisions), hockey stick (black, swung to strike the puck), and the person (in blue/red attire) actively propelling the puck toward targets. Motion originates from explicit physical forces (stick impact) and locomotion (player's stance shifts).

Background elements (building walls, concrete surfaces, ice rink) remain static throughout all scenes. No fluid motion (fire, water, smoke) or wind-driven effects dominate the video; the environment is controlled and stationary.


A person wearing a white t-shirt, black shorts, and dark cap leans forward over a table, manipulating two dark objects. They gradually bend their torso downward, adjusting the items on the tabletop and extending their arms toward the floor. The background includes a brick wall and wooden furniture. The camera maintains a fixed perspective with slight shake.

A person in a white shirt is performing push-ups, moving their body vertically with hands and feet fixed on the ground. Motion is clearly tracked as discrete locomotion.

Background elements (brick wall, wooden cabinet) show no shifting or fluid motion. No fire, water, smoke, or wind effects are present.


A hand holds a brush, applying purple paint to a hair design on a white surface. The brush moves across the hair strands, adding color. The camera remains steady, focused on the hand and the painting area.

A hand and brush are moving deliberately to apply paint to a paper surface; these are discrete solid objects exhibiting controlled motion.

The background (a static surface) shows no shifting or environmental motion; no fire, water, smoke, or wind is present.


A man wearing a dark shirt and headband plays a drum set on grass, using drumsticks to strike multiple copper-colored cymbals and a white snare drum. He transitions from a leaning posture to sitting while continuing to play. The camera maintains a top-down view with no significant movement.

Person's arms and drumsticks exhibit discrete motion as they strike drumheads; drums vibrate but remain mostly stationary.

Grass background is static and shows no significant wind movement or fluid motion; no fire, water, or smoke observed.


A child in a black and pink hooded snowsuit and black boots stands on a snow-covered deck bordered by a beige fence. Initially holding a red snow shovel aloft, they lower it, turn it to face downward, and position it vertically against the fence. The camera remains stationary with a slight overhead perspective.

A child (discrete solid object) is moving: lifting the red snow shovel, shoveling snow, and adjusting posture. Motion is driven by the child's physical forces and locomotion.

The background (snow-covered ground and wooden railing) shows no significant shifting or fluid motion. No fire, water, smoke, or wind is visible; snow is static except for the child's actions.


Two hands manipulate Mahjong tiles on a green surface. Initially, both hands hold four tiles each, positioned above a black tile row. The hands move tiles into the row, with the right hand subsequently placing five tiles while the left hand maintains four. The camera remains stationary in a top-down view, capturing the hands’ precise movements and tile arrangements against the green background.

Discrete hands move domino tiles in a controlled manner, with visible physical interactions such as picking up and placing tiles.

The green surface and dominoes in the background are static; no fluid or environmental motion (fire, water, wind) is present.


A woman in a gold dress and a man in a black suit jointly cut a decorated cake on a red tablecloth, while a person to their left films the action with a smartphone. The camera shows slight movement, capturing the couple’s coordinated motion as they slice the cake against an orange wall backdrop.

The couple (man in black suit, woman in gold dress) moves to interact with the cake, with the man's hand visibly cutting the cake. A person holding a phone is also present, but the primary motion involves the couple’s deliberate actions toward the cake.

The orange wall and tiled floor remain static across frames, showing no fluid motion or environmental effects like fire, water, or smoke. Background elements do not shift uniformly, ruling out ambient_environmental.


A man in a dark jacket and blue jeans stands facing away from the camera near a netted fence, then turns slightly as another man in a black jacket and white cap walks into the frame from the left and passes him. The second man moves to the right, exiting the foreground, while the first man remains in place. The camera pans left slightly during the second man's movement. Background details are minimal, showing a grassy area and distant structures.

Two individuals are moving: one person initially standing and then walking away from the fence, and another person entering from the left side of the frame and walking towards the fence.

Background elements (fence, houses, trees) are static and show no uniform shifting. No fluid or environmental motion observed.


A welder wearing a dark helmet with a blue visor works on a metal beam, generating bright sparks; they then lift the helmet to reveal their face. The camera remains fixed at a low angle, capturing the action from below with minimal background details.

A person wearing a welding helmet is moving their body and welding torch to perform welding, emitting bright sparks.

The background (wooden structure and workshop) is static. The welding process produces sparks but is not a dominant fluid or ambient motion; it's a discrete process.


RAW CAPTION: Got it, let's break this down. The video shows a dog being groomed. First, a hand is holding the dog's head, maybe trimming its fur. The dog has black and white fur, with a fluffy face. Then the hand moves, maybe adjusting the dog's position. The dog is being handled, so the actions are about grooming. The background is plain, so minimal description. Camera seems close-up, following the movement. Let's structure it chronologically: start with hand holding dog, then moving the dog, maybe the fur being cut. Need to be concise. Check rules: main subject is the dog, appearance (black and white, fluffy), motion (being groomed, held). Spatial: hand is near the dog. Camera perspective: close-up, maybe slight movement. Let's draft: "A hand holds a black and white fluffy dog’s head as it is groomed; the dog is adjusted and moved by the hand, with the background remaining plain. The camera maintains a close-up perspective, following the hand and dog’s motion." Wait, need to check if that's chronological. First, hand holds dog, then movements. Maybe "A hand gently holds and adjusts the head of a black and white fluffy dog during grooming; the dog is repositioned while the hand manipulates its fur. The camera stays in close-up, capturing the motion without significant background details." Hmm, make it concise. Let's see the video frames: first frame shows hand on dog's head, then hand moving, dog's face, then hair being cut. So the sequence is: hand holding dog's head, then moving the dog (maybe turning it), then the dog's face is shown with hair being cut. So the action is grooming, hand manipulating the dog's fur. The dog is black and white, fluffy. So caption: "A hand holds the head of a black and white fluffy dog, adjusting and trimming its fur during grooming; the dog is moved slightly as the hand works, with the camera maintaining a close-up perspective throughout the sequence." Wait, but need to be chronological. Start with the hand holding the dog, then the movement. Let me check the rules again. Focus on motion and behavior in chronological order. So: [0.0] hand holds dog's head; [1.4] hand moves upward (maybe lifting), [2.5] hand continues adjusting, [3.6] dog is held again. So the actions are the hand manipulating the dog's head and fur as part of grooming. The dog is black and white, fluffy. The background is plain. Camera is close-up, moving slightly to follow the hand. Let's write: "A hand adjusts and holds the head of a black and white fluffy dog during grooming; the dog is repositioned as the hand manipulates its fur, with the camera maintaining a close-up perspective that follows the hand and dog’s movements." Wait, maybe shorter. Let's check the example. The key is to be concise. Let's try: "A hand grooms a black and white fluffy dog by holding and adjusting its head; the dog is moved slightly as the hand works on its fur, with the camera staying in close-up throughout." But need to make sure it's chronological. Maybe: "A hand holds and manipulates the head of a black and white fluffy dog during grooming; the dog is repositioned and the hand continues trimming its fur, with the camera maintaining a close-up perspective." Yes, that seems to cover the sequence. Let's confirm all rules: a) motion in chronological order: hand holds, adjusts, repositions. b) appearance: black and white, fluffy, dog. c) spatial: hand near dog. d) camera: close-up, following motion. e) background minimal. f) no text. So the caption should be concise. Maybe: "A hand adjusts and holds the head of a black and white fluffy dog while grooming; the dog is moved slightly as the hand works on its fur, captured in close-up with minimal background detail." Wait, but need to mention the main subject's behavior. Let's check the video: the dog is being groomed, so the hand is cutting or trimming the fur. The dog is black and white, fluffy. So: "A hand grooms a black and white fluffy dog by holding and adjusting its head, moving the dog as the hand works on its fur; the camera remains in close-up, following the motion." Yes, that's better. Let's make sure it's chronological. First, hand holds head (grooming action), then moves the dog (repositioning), then continues grooming. So the sentence structure should reflect that. Maybe: "A hand holds the head of a black and white fluffy dog, adjusting its position during grooming; the dog is moved slightly as the hand continues trimming its fur, with the

A person's arm (with a visible light-colored sleeve) and a small animal (likely a dog with dark and light fur) are moving. The dog's head moves while the person's hand interacts with it.

The background consists of a plain, light-colored wall with no visible shifting or fluid motion (fire, water, smoke, wind).


A person in dark clothing runs from the left, pushing the skirt of a stationary bronze statue of a woman in a long dress, then exits to the right. A second person in dark clothing runs from the right, pushing the statue's skirt, then exits to the left. The statue stands centrally between two potted trees on a paved area, with a street and buildings in the background. The camera remains stationary, facing the statue directly.

Discrete solid objects moving: pedestrians walking/runners (e.g., person at 1.0s moving left-right, person at 4.0s moving right-left) and cars driving on the street.

The background (buildings, trees, street) shows no shifting or fluid motion. No fire, water, smoke, or wind effects are present.


A person feeds white paper sheets into a large dark gray industrial paper shredder, with shredded white paper accumulating on the ground. A second person stands near stacked bags of shredded paper in the background. The camera remains focused on the shredder, capturing the continuous paper feeding and shredding process.

A person's hand is seen moving to feed paper into a shredder, with shredded paper accumulating on the ground. The shredded paper pile grows as a result of the shredding process, but the primary motion is driven by the discrete object (hand) interacting with the shredder.

No shifting backgrounds or fluid/environmental motion observed (e.g., no fire, water, smoke, or wind). The shredded paper pile and static bags on the ground indicate a stable environment with minimal ambient influence.


A person in a pink hoodie and black pants moves from the corner toward the center of the room, adjusts their hoodie, and faces the camera. A second individual in blue jeans is partially visible on a top bunk bed. The camera remains stationary.

A person (in pink sweatshirt and black pants) is moving down a ladder from the top bunk to the bottom, with hand gestures (e.g., adjusting hair, waving) during descent.

The background (pink wall, framed picture, bunk bed) is static; no shifting background or fluid/environmental motion (fire, water, wind) is observed.


A line of camels, each carrying riders in vibrant traditional clothing, moves forward across a vast sandy desert. People in colorful attire, some walking alongside the camels, guide the caravan as it progresses. Shadows stretch long across the sand, indicating early morning light. The camera follows steadily from behind the caravan, capturing the motion of the camels and riders as they travel together.

Discrete objects (people and camels) are moving due to locomotion; their bounding boxes shift progressively across the frame as they walk through the desert.

The desert landscape and distant dunes show no fluid or environmental motion (e.g., fire, smoke, water). Background elements remain static with no uniform shifting across the frame.


A person in a dark wetsuit windsurfs on a board with a blue and black sail, gliding across the water while generating a trailing wake of splashes. The camera maintains a steady top-down view throughout the sequence.

A windsurfer (person with sail) is moving across the water surface, demonstrating locomotion driven by wind and water dynamics.

The water exhibits fluid motion (waves and turbulence), indicating ambient environmental motion. However, the windsurfer remains the focal point with distinct physical interaction.


A hand places a clear lid onto a pot containing green and red liquid on a stovetop, then secures the lid. Next, hands unfold a white paper package onto a dark surface and position a green apple on the paper. The camera maintains a top-down perspective throughout.

Hands place a green onion onto a sheet of paper; the onion and paper are solid, discrete objects with localized motion.

Static kitchen surfaces (stove, countertop) and gray work surface appear in all scenes; no shifting backgrounds or fluid/environmental motion (fire, water, wind) detected.


An adult in an orange shirt sits on the floor, holding a child in a pink outfit. The adult gently moves their hand toward the child's chest, then adjusts their hold while remaining seated. The child stays positioned in front of the adult, who maintains a close embrace. The background features closed doors and minimal furniture, with the camera capturing the scene from a static, eye-level perspective.

A person in an orange shirt and a child in a pink shirt are moving. The person is holding the child and performing deliberate actions (e.g., feeding, adjusting position) with observable hand and body movements.

The background (white door, floor, and static objects) shows no shifting or environmental motion. No fire, water, smoke, or wind is visible.


A shirtless man in red and white shorts confronts a man in a red shirt at the base of stone steps. The shirtless man shoves the red-shirted man, who falls backward onto the steps; the shirtless man then steps over the fallen man, who lies motionless on the ground. People nearby, including a child, clap as the shirtless man bends to check on the fallen man before standing up and turning away. The camera follows the action with slight shake, maintaining a ground-level perspective.

Discrete solid objects (shirtless man in red/white trunks, man in red shirt, surrounding bystanders) exhibit explicit physical motion: shirtless man bends over, interacts physically with the seated man, and performs locomotion (standing, shuffling), while bystanders react via hand gestures and movement.

Background elements (trees, distant structures, steps) show minimal uniform shifting. No dominant fire, water, or wind motion observed; environment is stable with no fluid/gaseous dominance.


A child with short dark hair, wearing a white shirt and dark pants, lies prone on a wooden floor. The child manipulates scattered puzzle pieces with both hands, moving them across the floor to assemble. The pieces remain on the floor around the child as the camera maintains a top-down perspective with slight movement.

Child's hands actively manipulating solid puzzle pieces through explicit physical movements (picking up, moving, placing pieces).

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


A woman wearing a pink tank top, black shorts, and pink shoes stands facing the camera with a jump rope extended in front of her. She begins jumping, swinging the rope beneath her body in a continuous circular motion while maintaining a wide stance. The background includes columns and potted trees, but the focus remains on her rhythmic jumping. The camera stays stationary throughout the sequence.

The woman is the primary discrete object performing jump rope exercises. Her body moves vertically and horizontally in a rhythmic pattern due to her locomotion, while the jump rope exhibits circular motion as it rotates around her hands.

The background (buildings, potted trees, stone pavement) remains static throughout the clip with no shifting, fluid motion, or environmental effects. No fire, water, smoke, or wind-induced motion is present.


A man wearing a black tank top, black shorts, and white sneakers bends down to pick up two dumbbells from the floor in a gym, then stands upright holding them at his sides.

Background elements (trees, ground) show no uniform shifting or fluid motion (e.g., fire, water, smoke); no wind-driven swaying evident in foliage.


RAW CAPTION: Got it, let's see. The video shows a fencing gym. There are multiple fencers. Let's check the sequence.

First frame: three fencers in the foreground, two moving, one maybe retreating. Then in the next frames, they're moving around. The main action is fencers engaging in bouts.

Need to note the motion chronologically. Let's break it down.

Start: Four fencers visible. Two in front, two in back. They're wearing white tops and black pants or light pants. Helmets on. They're using swords.

First, the two in front (maybe the main pair) are moving towards each other, then one steps back, another advances. Then the pair in the back also move, maybe a bout. Then more movement as they shift positions.

Wait, the video starts with four people, but maybe some are exiting. Let's check the frames:

Frame 0: 4 fencers. Two in front (left and right), two in back. All in fencing gear.

Frame 1: The two in front move towards each other, the back two also moving.

Frame 2: Front two are in a position where one is lunging, the other maybe parrying.

Frame 3: One of the front fencers steps back, the other advances.

Frame 4: Now the back fencers are moving into the foreground, maybe swapping roles.

Wait, but the problem says main subjects: need to track the main ones. Let's list the motions.

Chronological order:

- Initial position: four fencers on a mat. Two pairs engaging. They wear helmets, white shirts, dark pants. Left side (first pair) fencers move towards each other, then one steps back as the other advances. Then the other pair (right side) also engage. As the video progresses, the fencers shift positions, with some moving away from the central mat, others approaching.

Wait, maybe better to describe each frame's action:

At 0s: Four fencers (two pairs) on a dark mat. Two pairs are facing each other; left pair: one moves towards the right, the other steps back. Right pair: one moves towards left, other steps back. Background has gym equipment.

At 1s: The left pair is now closer, one has lunged (sword forward), the other is parrying. Right pair also advancing.

At 2s: Left pair: one steps back, the other continues to move. Right pair: one is retreating, other advances.

At 3s: The right pair fencers are now more central, moving towards each other. One fencer (right) steps away, another (left) advances.

At 4s: Fencers continue to shift; some move out of the mat area.

Need to focus on main subjects. Let's count: initially four, but maybe two pairs. Let's say there are two main fencers (front) and two others (back) engaging in bouts.

Now, appearance: all wear white tops, dark pants (some black, some light), helmets. Swords in hand.

Spatial relationships: The fencers are on a dark mat. In front of the mat is the wooden floor. The gym has walls with equipment.

Background: minimal, gym setting with a banner, equipment.

Now, camera: the camera seems static, maybe a slight pan as the fencers move. But the description says "conclude with camera perspective and movement". The video is likely a fixed camera shot, no major movement.

So the caption should be chronological:

"Four fencers in fencing gear (white tops, dark pants, helmets) engage in bouts on a dark mat in a gym. Initially, two pairs face each other; one fencer from each pair lunges toward the opponent while the other retreats. As the sequence progresses, the fencers shift positions, with some moving toward the mat’s edges and others advancing toward the center. The camera remains stationary, capturing the dynamic movements without significant shift."

Wait, need to check the number. In the first frame, four fencers. Then some move away. Let's see: at 0s, four. At 1s, maybe four. At 2s, same. Then at 3s, four. Then at 4s, three? Wait, no, the video is short. Let's look at the frames.

Wait the video shows:

Frame 0: four fencers.

Frame 1: same, but movements.

Frame 2: maybe one fencer moving away.

Frame 3: more movement.

But the key is main subjects' motion. Let's describe each step.

Start: Four fencers (two pairs) on a dark mat. All wearing helmets, white shirts, dark pants. One pair (left) moves toward each other: one advances, the other retreat

Multiple distinct solid objects (4+ people) exhibit locomotion through deliberate human movement (walking, shifting positions) on the mat. Their motion is tracked as discrete subjects without environmental influence.

The gym background (walls, wooden floor, equipment) remains stationary with no fluid motion (fire, water, smoke, wind) observed. Background elements show consistent positioning with no uniform shifting.


A person wearing a light blue long-sleeve top, black pants, and beige slippers sits on a bed with striped bedding, manipulating a rope by tying a knot. Their hands move the rope in front of them, adjusting the knot’s structure. A wooden nightstand is positioned to the right of the bed. The camera remains stationary in a top-down perspective, focusing on the hands and rope.

Person's hands and shoelaces exhibit discrete movement while tying laces; solid objects moving due to intentional physical action.

Background elements (bed, bedding, cardboard box) show no shifting or fluid motion; no fire, water, smoke, or wind present. Background remains stable with no camera-induced panning/tilting.


Five individuals in orange, blue, and black sportswear with helmets and sticks interact on a paved area marked with yellow lines and cones. The black-and-yellow-clad figure moves toward the center, gesturing, then walks left. The blue-red-helmet person shifts left, while the orange-white-helmet individual steps back. The blue-blue-helmet person stays near the bottom. The camera maintains a top-down perspective with no significant movement.

Multiple people (in colored uniforms) are moving: some run, others position themselves, and one player appears to hit a red ball. Each person and the ball are discrete solid objects moving due to locomotion and physical interactions.

The background consists of static elements (concrete ground with yellow lines and a wall) that do not shift uniformly across frames. No fluid or environmental motion (fire, water, wind) is present.


Gloved hands actively sorting and repositioning paper fragments within a shredder. Paper pieces are manipulated by discrete physical forces (manual handling).

No shifting background elements; machine structure remains static. No fire, water, smoke, or wind present. Ambient motion is negligible.


A man wearing a dark sleeveless shirt, light-colored pants, and a blue tool belt wipes a large window with a red cloth while standing in front of a brick building. He steps back, turns, and walks away from the window, moving toward the left side of the frame. The camera remains static throughout, capturing the man's movements against the brick wall and adjacent window.

A man is moving: cleaning the window and then walking away carrying cleaning tools. His motion is due to his own locomotion and physical actions.

No shifting background; no fire, water, smoke, or wind visible. The brick wall and window frame are static.


A person in an orange shirt and dark shorts stands on a raised platform, gesturing toward a large seated audience also wearing orange shirts. The camera pans left, revealing more of the seated crowd and the platform area, with the standing individual shifting position slightly while the audience remains attentive. The camera movement includes a slight pan to the left, capturing the spatial arrangement between the speaker and the seated group.

A standing speaker (orange shirt) performs controlled gestures and movements while addressing seated audience members, with minimal motion from the audience.

No shifting backgrounds or fluid/environmental motion detected; walls, barriers, and interior structures remain static with no signs of fire, water, smoke, or wind.


A yellow bulldozer with a large front blade advances steadily along a muddy dirt path, moving toward the camera. It travels past a tall earthen wall on the left, with visible tire tracks in the soil. The camera remains fixed throughout the sequence, observing the machine's approach.

A large dump truck is the only discrete object moving, traveling from left to right across the dirt road. Its motion is consistent with locomotion (engine-driven travel) with no visible collisions or secondary forces.

The rocky hillside and ground remain static throughout the sequence; no fire, water, smoke, or wind-induced motion is present. Background elements (e.g., hillside) do not shift uniformly, indicating no dominant ambient environmental forces.


A boy in a navy and white striped shirt with a green collar sits on a polished wooden floor, manipulating a blue gift box decorated with colorful patterns. He uses both hands to lift the box's lid, focusing on opening it. A green gift box with blue polka dots rests to his left, while wooden chairs and a table are visible in the background. The camera follows his actions with slight movement, maintaining a medium shot perspective.

The child is holding and manipulating a colorful box; the box's motion is due to the child's hands moving it.

The background (wooden floor, chair, green box) is static with no shifting or fluid/environmental motion. No fire, water, smoke, or wind observed.


A person in a red and white striped shirt with brown hair raises their hand to adjust their hair, then steps out of the frame before returning to continue the motion. The background includes brown walls and white doors. The camera remains static with a slight shake.

A woman is moving her arms and body (adjusting hair and shifting position).

Background (walls, door) is static. No fluid/environmental motion (fire, water, wind) present.


RAW CAPTION: Got it, let's break this down. The video shows a person in a white karate gi with a yellow belt. First, they're standing in front of a door, kicking a board (maybe a wooden board) that's mounted on a stand. Wait, the first frame shows the person holding the board? Wait, no, looking at the sequence: in [0.0], the person is holding the board, then [1.0] they kick it, [2.0] they move, [3.0] the board is gone, [4.0] they're standing. Wait, no, let's check the frames.

First frame: person in white gi with yellow belt, facing a door (maybe a cabinet), holding a white board (like a wooden board) in front of them, right arm extended. Then frame 1.0: they kick the board into the door? Wait, the action is kicking. Let's see: the sequence is [0.0] they hold the board, then [1.0] they kick it (maybe breaking it), [2.0] they jump back, [3.0] they're mid-air, [4.0] they land, [5.0] they stand. Wait, the video is split into frames with timecodes 0.0 to 5.0 maybe? Wait, the user provided 6 frames (0.0 to 5.0). Wait, the description:

[0.0] - person in white gi, yellow belt, holding white board (maybe a kickboard), facing a door (which has a cabinet with a box attached).

[1.0] - person swings arm to kick, board is in motion.

[2.0] - person kicks, board is being kicked towards the door.

[3.0] - person steps back, board hits the door (maybe breaking it).

[4.0] - person is in front of the door, now the board is on the floor.

[5.0] - person stands, hands out.

Wait, the key points: person in white uniform, yellow belt, kicking a board. The board is likely a wooden board used in martial arts for breaking. The action sequence: start with holding the board, then kick it, then the board flies through the door (or maybe the door is a target), then the person steps back. The background has a cabinet with shelves, a door, and a window. But background should be minimal. Focus on motion.

So chronological: a person wearing a white karate uniform with a yellow belt stands facing a door, holding a white board. They then kick the board, sending it into the door. The person steps back, and the board is no longer visible. The camera is static, probably a fixed position, showing the action from the side.

Check the rules:

a) Motion chronology: person holds board, kicks, steps back.

b) Appearance: white gi, yellow belt, white board (maybe a wooden board).

c) Spatial: person is in front of the door, board is held in front, then kicked into the door.

d) Camera: static, maybe slight shake? But the user's example says "camera perspective and movement" – the video probably has a static camera.

e) Background minimal: just mention door and cabinet if necessary, but rules say minimal unless essential. The door is the target, so maybe mention.

f) Exclude text, names, etc.

So structure: A person in a white karate uniform with a yellow belt holds a white board in front of a door, then kicks the board toward the door, steps back, and the board is no longer visible. The camera remains static.

Wait, in the frames, after kicking, the board is on the floor? Wait, frame [2.0] might show the board being kicked, then frame [3.0] person is mid-air, frame [4.0] they land, frame [5.0] they stand. So the action is kick, then the person moves back.

Wait, let's parse each frame as per the user's description:

[0.0] - person holds board, facing door.

[1.0] - person swings arm (kicking), board in motion.

[2.0] - person kicks, board flying towards door.

[3.0] - person steps back, board hitting door.

[4.0] - person is now in front of the door, board on floor.

[5.0] - person stands, hands out.

So the sequence: person holds board, kicks it, board hits door, person steps back, then stands.

Now, concise caption:

A person in a white karate uniform with a yellow belt stands in front of a door, holding a white board. They kick the board toward the

A person in a martial arts uniform is performing discrete physical actions: kicking, punching, and shifting stances. These movements are explicit, force-driven locomotion of a solid object.

The background consists of a stationary sliding glass door and static structural elements (e.g., cat tree). No shifting backgrounds or fluid/environmental motion (fire, water, wind) is observed.


A person lies on their back with their stomach exposed, partially covered by a light-colored sheet. Another individual’s hands, one wearing a watch, move rhythmically over the stomach area, pressing and smoothing the skin while the stomach displays green and black markings. The camera maintains a steady close-up perspective, focusing on the hands’ motion across the stomach.

Hands and the person's abdomen are moving due to physical interaction (pressure/massage), with hands actively manipulating the abdominal area.

Background elements (bed sheets, pillows) show no uniform shifting or fluid motion; no fire, water, or smoke visible.


RAW CAPTION: Got it, let's break down the video. First, the main subject is a person in a red shirt. They're at a table with food. The person is holding a plate with green food, maybe guacamole. Then they put the plate down, take a spoon from a dessert glass, and then pick up some food from a large platter. The platter has nachos or something with toppings. The background has emojis and a subscribe pillow, but we need to keep background minimal. Camera is probably static, top-down? Wait, the description says "camera perspective and movement." The video seems to be a fixed shot. Let's list the actions chronologically:

1. Person holds a plate with green food (guacamole maybe), then puts it down on the table.
2. They reach towards a large platter of nachos, pick up a piece with their hand.
3. Then they bring the food to their mouth.

Wait, the frames: [0.0] they hold the plate with green, then [1.4] they put the plate down, [2.5] they reach for the platter, [3.6] they take food from platter, [4.7] they bring food to mouth.

So the motion: the person in red shirt places a plate with green food on the table, then uses their right hand to pick up food from a large platter of nachos with toppings, and eats it.

Spatial relationships: the plate was held, then placed on the table. The platter is in front of them. The dessert glass (chocolate with whipped cream) is to the left.

Background: minimal, but there are emoji cushions, but we can mention if essential. The rule says exclude text recognition, so ignore "subscribe" pillow. But maybe just mention the cushions as part of the background, but keep minimal.

Camera: static, top-down? Wait, the video is likely a fixed camera, no movement.

Now, structure the caption:

A person in a red shirt places a white plate with green food on a table, then reaches for a large platter of nachos with toppings, picks up a piece, and brings it to their mouth. The table also holds a glass dessert with a spoon, positioned to the left of the platter. The background includes yellow emoji cushions. The camera remains stationary throughout.

Wait, check rules:

a) Motion chronological: yes, place plate, reach, pick, eat.

b) Appearance: red shirt, white plate, green food, platter (nachos), dessert glass.

c) Spatial: plate on table, platter in front, dessert to left.

d) Camera: stationary.

e) Background minimal: yellow cushions, but maybe just mention as part of the scene without detail.

f) Exclude text recognition: yes, no mention of "subscribe" or "like".

g) Think internally, but output caption.

So draft:

The person in a red shirt places a white plate containing green food on the table, then uses their right hand to pick up a portion of nachos with toppings from a large platter positioned in front of them, and brings it to their mouth. A glass dessert with a spoon sits to the left of the platter. The scene includes yellow emoji cushions in the background, and the camera remains fixed.

Check if "nachos" is accurate. The platter has chips and toppings, so maybe "a large platter of seasoned chips with toppings". But "nachos" is common. Alternatively, "a large platter of food with various toppings".

Wait, in the frame, it's a platter with chips, cheese, maybe salsa. So "a large platter of seasoned chips with toppings".

Also, the action: "places a white plate with green food", then "reaches for the platter, picks up a piece".

Let me rephrase:

A person in a red shirt places a white plate with green food on the table, then reaches toward a large platter of seasoned chips with toppings, picks up a piece with their right hand, and eats it. The table also holds a glass dessert with a spoon positioned to the left of the platter. Yellow emoji cushions are visible in the background, and the camera remains stationary throughout the sequence.

Check rules:

- Chronological: yes.

- Appearance: red shirt, white plate, green food, platter (seasoned chips), glass dessert.

- Spatial: plate on table, platter in front, dessert to left.

- Camera: stationary.

- Background minimal: yellow cushions mentioned, which is essential for context but minimal.

- No text recognition (no mention of subscribe/like).

Yes, this works.
</think>

<caption_output>A person in a red shirt places a white plate with green food on the table, then reaches toward

The man (discrete solid object) moves his hands and mouth to eat food from plates and a bowl. The motion is deliberate and due to his own physical actions.

The background (couch, lamp, bag) is static and unchanging. No fire, water, smoke, or wind motion observed. Ambient environmental motion is absent.


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

Frame 0: Person holds a black smartphone with a keyboard display, palm up. They're wearing a black and white striped sweater, hair in a bun. Background has a floral wallpaper, dresser, bed.

Frame 1-3: The person looks at the phone, then turns to the camera, smiling. Still holding the phone.

Frame 4: They raise the phone to eye level, screen visible.

Frame 5: They switch to a white smartphone, holding it up. The background is the same room.

Now, list the actions in order: starting with holding black phone, then looking at it, turning to camera, raising phone, then switching to white phone.

Appearance: person in black/white striped sweater, bun. Objects: black phone (keyboard display), then white phone. Background: floral wallpaper, dresser, bed. But keep background minimal.

Spatial: person is in a room, dresser to left, bed with pink chevron pattern to right.

Chronology: First, person holds black phone (keyboard visible), palm up. Then looks at phone, turns to camera, smiling. Next, raises black phone to eye level. Finally, switches to white phone, holds it up.

Camera perspective: seems static, no movement mentioned.

Need to make it concise. Let's draft:

A person in a black-and-white striped sweater holds a black smartphone with a visible keyboard display, palm facing upward, then turns to face the camera while holding the phone. They raise the phone to eye level, switching to a white smartphone with a blue screen, maintaining a static camera perspective.

Wait, check if all rules are followed. Motion in order: holding black phone, then turning, raising, switching. Appearance: sweater color, hair. Background minimal. Camera static.

Yes. Let's check the frames again. Frame 0: holding black phone. Frame 1-3: looks at phone, turns to camera. Frame 4: raises black phone to eye level (screen visible). Frame 5: switches to white phone. So the sequence is holding black, then turning, raising black, then white.

So the caption should capture that sequence.

Now, the final caption should be concise. Let's structure it:

A person in a black-and-white striped sweater initially holds a black smartphone with a keyboard display, palm up, then turns to face the camera while holding it. They raise the phone to eye level before switching to a white smartphone with a blue screen, maintaining a static camera perspective.

Wait, the white phone's screen is blue. In frame 5, the white phone shows a blue screen. But the rule says exclude text recognition. Wait, the instruction says: "Exclude text recognition, named characters, or stylistic analysis." So maybe we don't need to mention the blue screen, but the video shows the phone's screen. Hmm, but the rule says exclude text recognition, so perhaps just say the phone's screen is visible. Wait, but the user says "exclude text recognition", so maybe just describe the phone as a smartphone with a visible screen, not the content.

Wait, in frame 4, the black phone is held up, screen visible. Frame 5, white phone, screen visible. But the rule says exclude text recognition, so we don't have to say what's on the screen, just that it's visible.

So revise: "A person in a black-and-white striped sweater holds a black smartphone with a visible screen, palm up, then turns to face the camera while holding it. They raise the phone to eye level before switching to a white smartphone with a visible screen, maintaining a static camera perspective."

Check the frames:

Frame 0: black phone, keyboard display (so visible screen), palm up.

Frame 4: black phone held up, screen visible (probably same as before but now at eye level).

Frame 5: white phone, screen visible.

Yes.

Also, spatial relationships: the person is in a room with a dresser to the left and a bed with a pink chevron-patterned bedspread to the right. But rule e says background descriptions minimal unless essential. So maybe include only if needed. Since the actions are in the room, but the key is the motion. So maybe not necessary.

So the main focus is on the person's actions: holding, turning, raising, switching phones.

Let's write the caption:

A person in a black-and-white striped sweater holds a black smartphone with a visible screen, palm facing upward, then turns to face the camera while maintaining the phone's position. They raise the smartphone to eye level and subsequently switch to holding a white smartphone with a visible screen, all while the camera remains static.

Check the rules:

a) Motion in order:

The woman is moving her hand and the phone. The phone is a solid object being held and moved by the woman.

The background (wall, door, furniture) is static and does not shift uniformly. There are no fluid or environmental motions (fire, water, smoke, wind).


Two children, one in a black coat with white hood and red boots, the other in a red beanie, red scarf, and dark jacket, stand on opposite sides of a large black covered object in a snowy backyard. The first child walks left, then turns and moves right, while the second child shifts position to the right and turns. The camera remains stationary throughout.

Two individuals (wearing winter clothing) interact with a large black object covered in snow. One person shovels or clears snow from the object's surface, while the other observes or assists; their movements are discrete and driven by physical actions (e.g., shoveling, walking).

The wooden fence and snowy ground in the background show no uniform shifting or fluid motion. No fire, water, or significant wind-driven elements (e.g., blowing snow) dominate the scene.


RAW CAPTION: Got it, let's break this down. The video shows a hand writing the word "Color" in a notebook. First, the hand is at the 'l' and then writes the 'r' and 'color' part. Let's check the rules.

a) Motion: Hand is writing, starting from the 'l' and moving to complete the word. The hand is the main subject. The appearance: hand (skin tone, fingers), writing with a pen or marker. The word "Color" is formed in rainbow colors: red, orange, yellow, green, blue. But rule f says exclude text recognition, so maybe just mention the hand writing the word without specifying the text. Wait, no—rule f is exclude text recognition, so maybe don't say "Color", but the video shows the word. Wait, the task says "exclude text recognition", so don't mention the word. Wait, the user's rules: "f) Exclude text recognition, named characters, or stylistic analysis." So we shouldn't describe the word as "Color" but maybe just the action. Wait, the first frame shows the hand finishing the 'r' to make "Colo" (since the next frame is "Color"). So the hand is writing the letters.

b) Appearance: Hand (right hand, skin tone), pen (white, maybe a marker). The notebook has spiral binding (red spiral, white pages).

c) Spatial: Hand is over the notebook page, which is open. The spiral binding is at the top.

d) Camera: Top-down view, fixed? The video seems to be a close-up of the notebook and hand.

e) Background: Minimal, the notebook page with spiral binding.

So the chronological order: The hand is positioned over a white notebook page with a red spiral binding, holding a pen. The hand writes the letters of the word, starting from the existing "Colo" to complete "Color" (but since text recognition is excluded, maybe just "the word" but rule f says exclude text recognition. Wait, the rules say "exclude text recognition, named characters, or stylistic analysis." So we can't say "Color" but maybe describe the action as writing a word with rainbow colors? Wait, but rule f says exclude text recognition. Hmm, but the video shows the letters being written. Let's see: the video shows a hand writing a word in rainbow colors (red, orange, yellow, green, blue). But rule f says exclude text recognition. So maybe say "the hand writes a multicolored word" but no—text recognition would be identifying the word. So maybe better to describe the action without stating the word. Wait, the task says "focus primarily on the motion and behavior of main subjects". So the main subject is the hand writing. Let's think: The hand (right hand, skin tone) uses a pen to write on a white notebook page with red spiral binding. The hand starts writing the letters, completing the word (but since we can't name the word, maybe just "the word"). Wait, maybe the word is part of the motion, but the rules say exclude text recognition, so perhaps describe the colors as part of the writing action. Wait, the colors are red, orange, yellow, green, blue—so the letters are written in rainbow colors. But is that text recognition? Maybe not, since it's describing the colors of the writing, not identifying the word. So maybe that's okay.

So putting it all together:

A right hand holds a pen over a white notebook page with a red spiral binding, writing a multicolored word. The hand begins at the 'l' of the existing letters and completes the word, moving the pen across the page. The notebook is positioned centrally, with the spiral binding visible at the top. The camera maintains a fixed top-down perspective throughout the sequence.

Wait, but check the rules:

a) Motion: hand writes, starts at 'l' and moves to complete the word (so chronological: hand starts writing, completes the letters)

b) Appearance: hand (right, skin tone), pen (white?), notebook (white page, red spiral)

c) Spatial: hand over notebook page, spiral binding at top

d) Camera: top-down, fixed

e) Background: minimal

f) Exclude text recognition: so don't say "Color", but the video shows the letters. But since rule f says exclude text recognition, perhaps describe the action as writing letters without naming the word. But the video shows the letters as part of the action.

Wait, the task says "exclude text recognition, named characters, or stylistic analysis." So if the text is "Color", but we're not identifying the text (like "the word 'Color'"), but if we describe that the letters are colored, maybe that's okay.

Let's re-read rule f

A hand holding a pen is moving to write the word 'Color' on a spiral notebook page.

No shifting background or fluid/environmental motion. Background (spiral notebook) is static.

Discrete objects: a child (wearing a blue helmet) swinging a bat, and an adult assisting. The child's arm movements and bat motion are clearly visible as intentional physical actions.

The background consists of a fence and stationary elements (e.g., ground, distant vehicles) with no significant fluid motion (fire, water, smoke) or uniform background shifting.


A group of approximately 10–15 people, some standing and some seated, gather around a square platform in a dimly lit area. A person in dark clothing performs a forward somersault on the platform, rolling across the surface as the camera shifts to a lower angle, capturing their mid-air motion and landing. The individual then rises to a standing position, while the surrounding group remains stationary. The camera maintains a top-down view initially, then pans slightly to follow the subject’s movement.

A single person (dancer) is performing breakdancing moves (spins, rolls, handstands) with discrete physical motion, tracked by bounding box changes.

The background (railing and ground) remains static in the initial group scene and does not show fluid environmental motion (no fire, water, or smoke). The transition to the dancer’s close-up does not indicate background shifting.


A man in a black shirt and red shorts holds a dark medicine ball above his head, then bends forward to place it onto a black bench. He stands upright, hands on hips, while the camera remains stationary, capturing the sequence in a gym setting with minimal background details.

A person (wearing gray shirt and red shorts) is moving: lifting weights, bending down to place them on a bench, adjusting the weights, and standing up.

The camera remains steady, capturing the interaction in the classroom setting.

A person in a martial arts uniform (wearing a red belt) and an adult in a blue shirt are the discrete objects. The person performs controlled arm movements and stances, while the adult assists by holding a mat or providing guidance.

The background consists of static classroom elements (posters, walls, windows) with no uniform shifting or fluid motion. No fire, water, smoke, or wind effects are present.


RAW CAPTION: Got it, let's tackle this. First, I need to understand the video. The frames show two people, right? Let's check the descriptions.

In the first frame, a person is holding a bow, aiming, then releasing an arrow. Wait, the main subject is the person with the bow. Let's go chronologically.

Frame 0: One person is drawing a bow, aiming. The other is in the foreground, maybe obstructing? Wait, the video starts with the person holding the bow up. Then in frame 1, they're drawing the bow, arrow pulled back. Frame 2, drawing more. Frame 3, releasing the arrow. Then frame 4, maybe the arrow is released. Frame 5, the person is lowering the bow.

Wait, the video has a silhouette effect with high contrast, maybe from a glitch filter. But according to the rules, exclude stylistic analysis. So focus on motion.

Main subjects: two people. First person (the archer) is holding a bow, drawing the string back (from frame 0 to 3), then releasing (frame 3-4), then lowering the bow (frame 4-5). The other person is in the foreground, maybe watching or part of the scene, but the focus is on the archer.

Appearance: the archer is silhouetted, dark clothing, maybe a necklace. The other person is also silhouetted, dark. But according to the rules, mention appearance and number: color (dark), size (medium), orientation (one is the archer, the other is in front or beside? In the frames, the archer is on the right, the other on the left. So spatial relationship: the archer is to the right of the other person, who is in the foreground.

Motion: The archer starts by holding the bow up, draws the string back, releases the arrow, then lowers the bow. The other person is mostly still, maybe observing.

Background: minimal, maybe a light source, but minimal description.

Camera: The perspective is close-up, maybe handheld? The frames have a pixelated glitch effect, but camera movement is probably static? Wait, the rules say conclude with camera perspective and movement. The description says "slight shake" in the rules, but do we see that? The video has a distorted look, but maybe the camera is stationary but with some effect. Wait, the problem says "conclude with camera perspective and movement (e.g., top-down, pan left, slight shake)." So need to figure that out. The video starts with a close-up, maybe fixed camera but with a glitch, so "static close-up" or "slight shake" as per the glitch effect.

Wait, the frames are a sequence: the archer is drawing the bow, releasing, then lowering. So chronological order:

1. The archer (silhouetted, dark clothing) raises a bow, drawing the string back, with another person (silhouetted, dark clothing) positioned to the left, partially obscuring view.
2. The archer continues drawing the bow, arrow pulled back, while the other person remains in the foreground.
3. The archer releases the arrow, the bow is lowered slightly.
4. The archer lowers the bow after releasing.
5. The archer's motion completes, bow held down.

Wait, need to make it concise. Let's structure:

In the sequence, a silhouetted individual (dark clothing) draws a bow, pulls the string back, releases an arrow, then lowers the bow. Another silhouetted figure stands to the left in the foreground, partially obscuring the archer. The camera maintains a close-up, static perspective with minimal movement, focusing on the archer’s actions against a high-contrast background.

Wait, but rules say "briefly describe appearance and number". So "two silhouetted individuals, one in dark clothing holding a bow, the other partially visible in the foreground".

Motion: First, the archer raises the bow and draws the string back, then releases the arrow, then lowers the bow.

Spatial: The archer is positioned to the right of the foreground figure, who is partially blocking the view.

Camera: Close-up, static.

Background: minimal, high-contrast.

Let me check the rules again:

a) Motion in chronological order.

b) Appearance (color, size, orientation). Two people, silhouetted (dark), medium size, one (archer) holding bow, other in foreground.

c) Spatial: archer to the right of the other person (left side).

d) Camera: close-up, static (or slight shake? The video has glitch, but the problem says "slight shake" as an example, but if the video is static, then static. Maybe

Two human figures (discrete solid objects) exhibit intentional motion: the figure on the right manipulates an object (e.g., weapon) and moves toward the left figure, while the left figure remains relatively stationary with slight head/body adjustments.

No fire, water, smoke, or wind detected. Background elements (walls/structure) remain static despite visual artifacts; no fluid/environmental motion dominates.


A man with a beard, glasses, and gray tank top holds a blue object near his face, then lowers it to reveal a dark cap; he sits in front of bookshelves filled with books. The camera remains in a close-up position with steady framing.

The man (wearing a cap and tank top) and the microphone he holds are discrete solid objects moving through intentional locomotion (head movements and microphone manipulation).

The bookshelves in the background show no uniform shifting or distortion. No fire, water, smoke, or wind is visible; the environment is static and dry.


A young girl with light brown hair, wearing a white shirt with a butterfly design, sits in a high chair at a wooden table. A pink cloth with small items rests on the table. A medium-sized golden retriever enters from the left background, walking behind the high chair. The girl turns her head to look at the dog as it moves closer, then turns back toward the table. The camera remains stationary, capturing the scene from a fixed angle with no visible movement.

Child moves head and body (turning, looking around, yawning), dog enters frame and moves toward table; both exhibit solid, discrete motion due to intentional locomotion.

Background elements (floor tiles, door, furniture) remain static and show no shifting or fluid motion; no fire, water, smoke, or wind present.


A person wearing a red shirt, black shorts, white shoes, and a red cap stands in a hallway. They begin walking toward the camera, extending their arms outward as they move forward at a steady pace. The hallway has doors on the right and decorative streamers on the left wall. The camera remains stationary, capturing the person's motion from a fixed position down the hallway.

A single human subject (wearing red shirt, black shorts, red cap) is moving. The subject's motion is locomotive walking with arms swinging, clearly distinct from the background.

The hallway walls and floor remain static throughout the clip with no shifting backgrounds or fluid/environmental motion (fire, water, smoke, wind). Background elements like doors and wall decorations show consistent positioning without uniform displacement.


RAW CAPTION: Got it, let's break this down. The video shows a breakdancer in a room with people around. First, the dancer is on the floor doing a spin, then moves to a handstand or some move, then transitions to a backflip or rolling motion. Let's check the timestamps.

Frame 0: Dancer on floor, body horizontal, legs bent, moving. Maybe a windmill or something. Frame 1: Still on floor, maybe rolling. Frame 2: Starts to get up, hands on floor. Frame 3: Standing? Wait, no, frame 3 shows the dancer in a crouched position, maybe a power move. Frame 4: Dancer rolls on the floor, then stands up. Frame 5: Dancer is on hands, maybe a handstand.

Wait, need to be chronological. Start with the first action: dancer performs a floor move (spinning on back), then transitions to a move where they lift legs, then another roll, then stands up. The background has an audience, but keep it minimal.

Appearance: Dancer is wearing a dark top and light pants, maybe a shirt with green? Wait, frame 0: blue shirt? Wait, frame 0: "dark top and blue shirt" maybe. Wait, the first frame: person in black shirt, blue pants? Wait, no, first frame: "dark top and blue shirt" — no, looking at the video: frame 0: person in dark top and blue shirt, lying on floor, spinning. Then frame 1: same person, still on floor, maybe moving. Frame 2: person stands up, maybe a handstand. Frame 3: person is in a crouched position, maybe a backflip. Frame 4: person rolls on floor. Frame 5: person is standing on hands.

Wait, the main subject is one person. So chronological: the dancer begins in a horizontal position on the floor, performing a spinning move. Then transitions to a crouched stance, followed by a roll across the floor, and finally stands upright. The background has a crowd, but minimal.

Now, camera perspective: the video is shot from a fixed position, maybe slightly shaky. So "camera remains steady with slight shake".

Let's structure the caption:

"A breakdancer in dark top and light pants performs a series of floor moves. Initially horizontal on the floor, spinning with legs bent, then transitions to a crouched stance, followed by a roll across the floor, and finally stands upright. The dancer's movements occur in a large indoor space with an audience in the background. Camera remains steady with slight shake."

Check the rules: chronological order, mention appearance (dark top, light pants), motion (spinning, crouched, roll, stand), spatial relationships minimal (audience in background), camera movement (steady with slight shake). Background description minimal.

Wait, need to check the exact frames:

Frame 0: dancer on floor, body horizontal, spinning (possibly a windmill). Legs bent.

Frame 1: same dancer, continuing the spin, maybe shifting.

Frame 2: dancer moves to stand, maybe a handstand? Wait, frame 2: "dancer is upright, body bent forward", but maybe a power move.

Frame 3: dancer is lying on back, legs up.

Frame 4: dancer rolls to the side, then stands.

Frame 5: dancer is on hands, body vertical.

Wait, maybe better to list the sequence:

Starts on floor, spinning (frame 0-1), then does a handstand or power move (frame 2), then rolls (frame 3-4), then stands (frame 5).

So the caption should be:

"A dancer in dark top and light pants begins on the floor, spinning horizontally with legs bent. They transition to a crouched stance, then roll across the floor, and finally stand upright. The background features an audience in an indoor setting. Camera remains steady with slight shake."

Wait, but the first frame is "0.3 seconds" — let's see the video:

0.0: dancer on floor, back to camera, legs up.

0.3: dancer on floor, body horizontal, legs bent, spinning.

1.4: dancer is moving, maybe rolling.

2.5: dancer is standing, arms up.

Wait, maybe the exact sequence:

Frame 0: dancer lying on back, legs up (head down).

Frame 1: dancer is on the floor, body horizontal, spinning.

Frame 2: dancer is in a crouched position, legs bent, arms out.

Frame 3: dancer rolls to the side.

Frame 4: dancer is on the floor, body flat.

Frame 5: dancer stands on hands.

So chronological: starts lying on back, spins horizontally

A person performing breakdancing moves (rolling, spinning, handstands) with clear physical interactions (e.g., ground contact, limb movements).

Static background elements (walls, floor, distant people) show no uniform shifting or fluid motion; no fire, water, smoke, or wind detected.


RAW CAPTION: Got it, let's break this down. First, I need to watch the video and describe the actions chronologically. The video has two people. Let's see the sequence.

At the start, maybe one person is standing or moving. Then there's interaction between them. Let's check the frames:

Frame 0: Two people in a room, maybe one is moving towards the other.

Frame 1: One person in a white striped shirt (maybe) is active, the other is sitting.

Frame 2: The standing person is moving, maybe jumping or swaying.

Frame 3: The person in the striped shirt sits down, the other is next to them.

Frame 4: The striped-shirted person is leaning back, the other is still sitting.

Frame 5: They're both seated, maybe talking or laughing.

Wait, the key is to note motions. Let's list the actions step by step.

First, the person in a light-colored striped shirt (maybe white with stripes) is moving energetically. Then they sit down, and the other person is seated next to them. Then the striped-shirted person adjusts their position, and they interact, maybe laughing. The background has a door, some lights, but minimal. Camera seems to have a slight shake, maybe handheld.

Wait, the description needs to be chronological. So:

- Initially, the person in the striped shirt is moving (maybe waving or gesturing), then sits down next to the other person who is already seated. Then they both sit, with the striped-shirted person leaning back, and the other looking at them. Then they both appear to be interacting, maybe smiling or laughing.

Now, appearance: two people. One wears a white striped shirt (light color, stripes), the other in dark clothing. The background has a door, a wall clock, some plants, but minimal as per rules.

Spatial relationships: the striped-shirted person moves towards the seated person, sits beside them. They are seated on a couch or chair.

Camera perspective: handheld, slight shake, maybe moving a bit but not much. The lighting is from a light source on the left, so maybe the camera is positioned to capture the room with some light from the door.

Now, following the rules: focus on motion, chronological order.

Let me structure:

In a dimly lit room with a wooden door and wall clock in the background, two individuals interact. The person in a light striped shirt moves energetically, then sits on a couch next to the other person, who remains seated. The striped-shirted individual leans back while the second person faces them, leading to mutual laughter. The camera remains handheld with slight shake, capturing the seated pair from a frontal angle.

Wait, need to be concise. Let's check:

"Two individuals in a dimly lit room: one in a light striped shirt moves and sits on a couch beside another person in dark clothing, who remains seated. The striped-shirted individual leans back, then both interact with smiles. The camera, handheld with slight shake, captures them from a frontal perspective."

Wait, the video starts with the striped-shirted person moving, then sitting. Let's check frame 0-5:

Frame 0: Both are present, maybe one moving towards the other.

Frame 1: Striped shirt person is active, moving arms.

Frame 2: Striped shirt person is still moving, maybe jumping or swaying.

Frame 3: Striped shirt person sits, the other is seated.

Frame 4: Striped shirt person leans back, other is sitting.

Frame 5: Both seated, maybe laughing.

So chronological: The person in the light striped shirt moves energetically before sitting down on a couch next to the other individual, who is already seated. They interact closely, with the striped-shirted person leaning back, leading to mutual laughter. The camera, handheld, captures the scene with a slight shake from a frontal angle in a dimly lit room.

Check the rules: a) motion in order. b) appearance: two people, one light striped, one dark. c) spatial: seated next to each other. d) camera: handheld, slight shake, frontal. e) background minimal. f) exclude text, etc.

Make sure to be concise. Let's draft:

"In a dimly lit room, one individual in a light striped shirt moves energetically before sitting on a couch beside another person in dark clothing. The striped-shirted person leans back, and both interact with smiles. The camera, handheld with slight shake, captures them from a frontal angle."

Wait, check the number of people: two. Appearances: light striped shirt (probably white with stripes), dark clothing. Motion: move, sit, lean back, interact. Background: dim, room with door, clock (but minimal). Camera: handheld shake.

Yes, that should work

Two people: one in white shirt moves from couch to door and back (locomotion), the other in green shirt is mostly stationary with minimal movement.

No fire, water, smoke, or wind visible. Background walls and door are static, no fluid motion.


A person wearing a dark green sweater over a white shirt and dark pants holds a white plate in one hand, bringing a piece of food to their mouth to eat, then lowers the food and writes on the plate. The individual stands centered in a dimly lit room with faint blue lighting in the background, and the camera remains static throughout the sequence.

A person is moving their arms and hands, manipulating an object (possibly a bag or container) in a discrete, solid manner. The motion is localized to the person's body and hands, showing deliberate movements without fluid-like characteristics.

The background contains a static blue light source with no visible shifting or fluid motion (e.g., no fire, water, or smoke). No ambient environmental motion is detectable.


A pair of hands manipulates a green apple cut into wedges on a green cutting board; a yellow apple slice and a white peeled apple rest to the left and below. The hands press the wedges together, adjust their position, separate them to reveal the core, then lift the wedges. The camera maintains a top-down view with no noticeable movement.

Hands and an apple are moving: hands apply force to cut the apple, causing discrete motion of the apple slices and the hand's position.

The background (green cutting board, wooden surface) shows no uniform shifting or fluid motion (e.g., fire, water, smoke). No environmental elements like wind are present.


A light-colored sewing machine stitches a red floral pattern onto pink fabric as a person's arm guides the fabric beneath it. The machine’s needle moves rhythmically, forming the design while the arm remains steady above the material. The camera maintains a close-up, top-down perspective, focusing on the stitching process with minimal movement.

The sewing machine needle moves rapidly up and down, and the fabric is fed through the machine by the machine's feed mechanism. A hand guides the fabric slightly.

The background (sewing machine body and table) is static. No fluid or environmental motion (fire, water, wind) is present.


RAW CAPTION: Got it, let's break down the video frames. First, the video starts with a frame showing an easel with a canvas, but the first frame has a red "INTV" logo. Then it transitions to the easel with a white canvas. The next frame shows a person using a brush on the canvas, and then they start painting—first a yellowish color, then maybe more colors.

Wait, the user's task is to create a concise chronological paragraph. Let's list the key elements:

- Frame 0: Easel with canvas (INTV logo), but maybe the logo is part of the initial frame but not to include text. Wait, rule f says exclude text recognition, so we can ignore the INTV logo.

- Frame 1: Easel with canvas, maybe the person is moving into the frame.

- Frame 2: Person’s hands with a brush and a palette, starting to paint.

- Frame 3: They apply yellow paint to the canvas.

- Frame 4: The canvas now has more yellow, so the painting is progressing.

Now, the main subject is the person painting. The person’s hands are visible, using a brush. The canvas is on an easel. The palette is on a blue box.

Chronological order: The video begins with an easel holding a canvas, then a person's hands appear holding a brush over a palette. The hands dip the brush into the palette, then apply yellow paint to the canvas, covering the sketch.

Spatial relationships: The person is standing in front of the easel. The palette is on the blue box (which is on the table next to the easel). The canvas is mounted on the easel, positioned vertically.

Camera perspective: The camera is steady, focusing on the canvas and the person's hands. It's a medium close-up, maybe slightly zooming in on the action.

Background: Minimal, dark gray walls, so not essential. Focus on the action.

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

Start with the setup: An easel with a white canvas is positioned against a gray backdrop. A person’s hands enter the frame, holding a paintbrush over a white palette placed on a blue box. The hands dip the brush into the palette, then apply yellow paint to the canvas, gradually covering the sketch. The camera remains steady, focusing on the painting process from a medium close-up angle.

Check rules:

a) Motion: Hands painting, brush moving.

b) Appearance: Hands (color? not specified, just hands), brush (wooden?), palette (white), canvas (white). Size: hands are in focus, palette on blue box.

c) Spatial: Canvas on easel, palette on blue box next to easel, hands in front.

d) Camera: steady, medium close-up.

e) Background: minimal (gray walls), so don't mention unless essential. The gray backdrop is the background, so maybe just "gray backdrop" but rule e says minimal. Maybe not necessary.

f) Exclude text, so no INTV.

g) Don't output reasoning.

Now, check the provided examples. The user's video:

[0.0 seconds] shows an easel with canvas (INTV logo on top left). [1.4] same but maybe zoomed? [2.5] hands with brush and palette. [3.6] hands painting. [4.7] canvas with yellow paint.

Wait, the actual frames:

Frame 0: Easel with canvas, maybe the canvas has a drawing, and the INTV logo is visible. But since rule f says exclude text recognition, we don't mention the logo.

Frame 2: Hands holding brush over a palette, which is on a blue box. The person applies paint to the canvas.

Frame 3: Canvas now has yellow paint.

Frame 4: More yellow, so the painting is progressing.

So the sequence is:

The video opens with a painting setup: an easel holds a canvas against a gray backdrop. A person's hands enter, holding a brush over a white palette resting on a blue box. The hands dip the brush into the palette and apply yellow paint to the canvas, gradually covering the sketch. The camera remains stationary, focusing on the hands and canvas from a medium close-up perspective.

Wait, the first frame (0.0 seconds) has the INTV logo, but we exclude text. So the initial scene is the easel with canvas. Then the hands come in.

Let's make it chronological:

At the start, an easel with a blank canvas is set against a gray backdrop. A person's hands appear, holding a paintbrush over a white palette placed on a blue box. The hands dip the brush into the palette and apply yellow paint to the canvas, covering the sketch as the painting progresses. The camera

A hand holding a brush moves to apply yellow paint onto a canvas; the brush and hand are discrete solid objects moving due to painting action.

Background shows static dark wall and easel structure with no shifting or fluid motion (no fire, water, smoke, or wind).


A man in a black suit and a woman in a white dress with a pearl necklace and white gloves stand side by side in front of a white, multi-tiered cake adorned with blue decorations. They each grasp a knife and begin cutting the cake together, their hands moving downward in unison. Behind them, guests are seated at a table covered with a white cloth. The camera remains steady, focusing on the couple’s coordinated action at the cake.

The groom and bride (discrete solid objects) are actively moving to cut the cake; their locomotion and interaction with the cake constitute explicit physical motion.

Background elements (walls, seated guests) are static with no fluid or environmental motion (e.g., fire, water, wind); no uniform shifting indicates camera motion is not dominant.


An athlete in a maroon shirt and white shorts walks toward the throwing circle, then begins spinning in place while preparing to release a heavy implement. The athlete’s body rotates multiple times within the circle before launching the object. The camera remains stationary, capturing the action from a fixed position behind the netted throwing area, with minimal background detail visible beyond the field and distant trees.

The athlete (a solid discrete object) performs controlled rotational and linear motions during a shot put throw, with movements driven by physical forces (muscle contractions, torque generation) within the throwing circle.

The background elements (trees, fence, grass) remain stationary and show no significant shifting or fluid motion. No fire, water, smoke, or dominant wind effects are present.


RAW CAPTION: Got it, let's break this down. The video shows two young girls dancing. First, I need to describe their actions chronologically. They're in a room with a window curtain and wooden floor. Both are wearing purple tops, blue tutus, and polka dot leggings. They start by dancing together, moving their arms and legs. Then they might switch positions or move around. Let's check the frames: in frame 0, they're both dancing. Frame 1: still dancing. Frame 2: one turns, maybe spins. Frame 3: they hold hands? Frame 4: one is in front, the other behind. Frame 5: they're apart again. So their motion is dynamic—dancing, turning, moving around.

Appearance: two girls, similar height (young kids), purple sleeveless tops, layered blue and purple tutus, gray leggings with blue dots, blue hair bows. Spatial: they move relative to each other, sometimes near the window, but the curtain is behind them. Background: light green walls, window with sheer curtain, wooden floor. Camera is static, no movement mentioned, so fixed perspective.

Rules say focus on motion, appearance, spatial if relevant, conclude with camera. Keep background minimal. So structure: describe the two girls' actions in order.

Start: Two young girls in purple tops, blue tutus, and polka dot leggings dance in a room. They begin moving their arms and legs energetically, occasionally spinning and changing positions relative to each other. One girl turns to face the other, then they move apart before coming together again. The camera remains fixed throughout, capturing their synchronized and individual movements against a backdrop of light green walls and a window with a sheer curtain. Wait, but background should be minimal. So maybe omit the curtain details? Wait, rule e: "Keep background descriptions minimal unless essential for understanding motion." The window is part of the room, but maybe not essential. So just mention the room's general setting? No, the problem says "minimal". Let's see the example. Maybe "in a room with light green walls and a wooden floor" but maybe too much. Wait, the video shows a window with a curtain, but is that essential? The motion is dancing, so maybe the background is just the room. But let's check the rules again. The caption should be concise.

Let's draft: Two young girls, each wearing purple sleeveless tops, layered blue and purple tutus, and gray polka dot leggings with blue hair bows, dance in a room. They move energetically, spinning and changing positions relative to each other; one girl turns to face the other, then they move apart before repositioning. The camera remains static, capturing their movements against light green walls and a wooden floor. Wait, but need to be concise. Let's see the rules: "concise, chronological paragraph".

Let's list the key points:

- Two girls, appearance (color, size, orientation): two young girls, purple tops, blue/purple tutus, polka dot leggings, blue bows.

- Motion: start dancing, move arms/legs, spin, change positions (one turns, then move apart, then come together).

- Spatial: relative to each other, moving in the room.

- Background: minimal, so just room with walls and floor.

- Camera: static, fixed.

So put it together: Two young girls in purple sleeveless tops, layered blue and purple tutus, and gray polka dot leggings with blue hair bows dance in a room. They begin by moving their arms and legs energetically, then spin and change positions relative to each other, sometimes facing each other or moving apart. The camera remains static throughout.

Wait, check the frames: frame 0-5 show them dancing, turning, interacting. So chronological: start dancing, move, spin, interact (one turns, then move apart, then maybe move towards each other).

Let me check the actual frames:

[0.0] Both dancing, arms up.

[1.0] Still dancing, one is slightly behind?

[2.0] One turns, holding hands?

[3.0] One is in front, the other behind, turning.

[4.0] One moves away, then the other.

[5.0] They are apart, one on left, one on right, dancing.

So chronological: Two young girls in purple tops, blue/purple tutus, and polka dot leggings dance in a room. They start by moving their arms and legs, then one girl turns to face the other, they hold hands briefly, then move apart and continue dancing.

Wait, but need to be precise. Let's make sure not to include extra details.

Final caption: Two

Two young girls in tutus are dancing, moving their arms and legs and spinning. Their motion is due to their own physical activity.

The background (wall and curtain) is static with no fluid motion (fire, water, smoke, wind). The curtain is stationary and the wall does not show any movement.


A hand moves colorful, patterned heart-shaped paper cutouts on a dark surface, adjusting their positions left and right. The hearts display multicolored floral designs and varied orientations. The camera pans to reveal additional hearts and a flower-shaped cutout, maintaining a top-down perspective with subtle movement.

A hand moves paper cutout objects (hearts, clouds) across the board. The hand is applying physical forces to relocate the cutouts.

The background (dark board) is static; no shifting backgrounds or fluid/environmental motion (fire, water, wind) observed.


A hand holds a thin metallic rod with a small hook, moving it toward a pair of metal pliers (with a green band) clamping a small cylindrical object. The hand adjusts the rod's position relative to the pliers, with fingers manipulating the rod's orientation. The background is a blurred blue surface. Camera remains close-up and steady throughout.

Discrete solid objects (hands and a small tool) are actively manipulated, showing precise movements to adjust or interact with the object in the pliers.

The background consists of a static blue fabric with no shifting or fluid motion (e.g., no fire, water, smoke, or wind-driven elements).


Two individuals are visible in a static shot; the first has long blonde hair and wears a light blue top, positioned left of center, while the second has glasses and brown hair, positioned to the right. The blonde covers her mouth with her hand, followed by the second person covering their mouth, then the blonde opens her mouth wide. A wooden door appears in the background.

Two people are moving their hands to cover and uncover their mouths, which is a discrete, solid object motion.

The background (wooden door and wall) is static with no shifting or environmental motion (fire, water, wind).


A person in checkered pants and a person in a white shirt and dark shorts run along a dusty dirt path. Initially, the checkered pants individual leads, followed by the white-shirted person. The white-shirted person then overtakes and runs ahead, while the checkered pants individual trails behind. Both continue running, with the white-shirted individual turning and the checkered pants person maintaining distance. The camera follows their movement, capturing the path and occasional background structures with a slight shake.

Two people are running on a dusty road. One person (in white shirt and dark shorts) is the main subject and moves across the frame. The motion is due to their own locomotion.

The background (trees, buildings) is static and does not shift uniformly. There is no dominant environmental fluid motion (fire, water, smoke, wind). The dust is a byproduct of discrete object motion.
