A person in a blue jacket and dark pants slides down a snowy slope, initially lying on their back with arms raised, then shifts to a seated position, and eventually stands up. The background shows a brown, grassy area beyond the snow. The camera maintains a stationary top-down perspective throughout.

A person in dark clothing is sliding down a snowy slope, moving with a consistent downward trajectory due to gravity and friction.

The background consists of a static, dry grassy hillside with no shifting or environmental effects (fire, water, smoke, wind).


A gray-haired person in a black top adjusts a long red and gold ribbon on a small Christmas tree, moving it upward and around the branches. A white-haired individual in a purple dress stands to the right, observing the process. The background includes green wreaths and a wooden table with miscellaneous items. The camera remains stationary throughout.

Two individuals: one actively adjusting Christmas tree decorations (hands moving to position ribbons/ornaments), the other partially visible. Their motions are driven by intentional physical actions.

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


Two workers, one in a blue shirt and one in a white shirt, crouch near a row of concrete blocks on a paved area. A third person in dark clothing walks from the right side of the frame across the scene, passing the workers, then exits to the left. The camera remains static throughout, capturing the scene from a fixed perspective with houses and construction equipment visible in the background.

Two distinct people: one person bends and moves on the ground, while another person walks across the scene, interacts briefly, and exits the frame.

Static background elements (buildings, ground, wall) show no shifting or environmental motion (no fire, water, smoke, or wind).


A child with dark hair in pigtails, wearing a pink and white striped shirt, interacts with a tall green plant, reaching up to adjust its leaves. The child turns, revealing their back as they move slightly, remaining in front of the plant. The camera shifts from a top-down view to a shaky perspective following the child’s motion, with an orange wall and gravel visible in the background.

A child (solid object) moves her arm and body to water a plant using a watering can. The motion of the child is due to explicit physical forces (her own actions).

Background (orange wall and patterned carpet) is static and does not shift. No dominant fluid/environmental motion (fire, water, smoke, wind) observed; water spraying is a controlled event by the child and not ambient.


A baby in a pink polka-dot top is held by an adult, facing the camera. An adult hand brings an orange popsicle to the baby’s mouth, who then takes it. The background includes a brown couch, and the camera remains close-up with slight movement.

The baby (wearing pink polka dot outfit) is moving its head and arms. The carrot is being held and moved by an adult hand to the baby's mouth. The carrot is then bitten by the baby. These motions are due to physical interactions (hand moving carrot and baby eating).

Background shows a static couch and room. No fire, water, smoke, or wind motion. Background elements do not shift uniformly.


A man in a gray shirt and dark pants crouches on a wooden floor arranging wooden train tracks while a child in a yellow shirt and green pants sits nearby. The child stands, runs away from the tracks, and returns to interact with the pieces as the man continues assembling. The camera remains static, capturing the scene from a fixed perspective.

Two people (adult and child) are moving and interacting with a wooden board and puzzle pieces; they pick up, place, and reposition objects on the board.

The background (walls, floor, furniture) is stationary with no visible shifting. No fire, water, smoke, or wind is present.


A person with long dark hair and a light blue shirt first adjusts their hair with one hand, then uses both hands to pull down or adjust their shirt. The camera maintains a close-up perspective with slight shake, focusing on the individual from the shoulders up against a plain background.

A person manipulates a solid object (possibly a phone) with their hands, exhibiting hand and arm movements.

No shifting background; no fluid or environmental motion observed.


A male hockey player in a yellow sleeveless top, black shorts, yellow socks, and blue cleats prepares to take a shot on a blue field, positioning himself with a yellow ball at his feet. He swings his hockey stick, making contact with the ball, which rolls forward. Other players in yellow uniforms stand and sit near the purple sideline in the background. The camera follows the player’s motion with a slight shake.

A hockey player in a yellow uniform actively manipulates a hockey stick and ball, demonstrating controlled motions (swings, positioning) and ball displacement due to stick impact.

The blue and pink field, boundary lines, and background personnel (e.g., officials, spectators) remain static across frames. No fire, water, smoke, or wind-driven motion is observed in the environment.


RAW CAPTION: Got it, let's break this down. The video shows a hand interacting with a gong. First, the hand is holding a mallet, then hits the gong, causing the mallets to fall. Then the gong is seen without the mallets. Let's check the rules.

Main subject: a hand and the gong. The hand moves to strike the gong, then the mallets (two? wait, in the video, the hand uses a mallet, then two mallets are shown on the floor). Wait, in frame 0:00, the hand is holding a mallet (one mallet? maybe two but one is being held). Then at 0:02, the hand drops the mallets onto the floor. So first, the hand strikes the gong, then the mallets fall. Then the gong is still there but mallets are on the floor.

Appearance: gong is golden with black Chinese characters, mounted on a stand. Mallets are wooden with rounded heads. Hand is visible, moving.

Chronological order: hand holds mallet, strikes gong (causing a sound, but we don't describe sound), mallets fall onto the carpet. Then the gong is stationary with mallets on the floor. Camera is static? Wait, in the video, the camera might have a slight movement, but looking at the frames: frame 0:00 to 0:05, the camera angle changes a bit? Wait, the description says "camera perspective and movement". Let's see the video: the initial shot is a close-up of the gong, then as the hand moves, maybe the camera is static. Wait, the video frames: the first frame shows hand hitting gong, then the hand moves away, mallets fall, then the camera might pan or move? Wait, in the description, the user provided frames 0.0 to 5.0. Let's check the movement.

The caption should be concise, chronological. Steps:

1. A hand holding a wooden mallet with a rounded head strikes a golden gong with black Chinese characters, which is mounted on a stand on a floral-patterned carpet. The hand then releases the mallet, causing both mallets (since there are two mallets shown on the carpet later) to fall onto the carpet. The gong remains stationary after the strike. The camera remains static throughout, focusing on the gong and the hand's actions.

Wait, but in the video, how many mallets? In frame 0:00, the hand is holding one mallet? Wait, the first frame shows a hand with a mallet, then in frame 0:02, two mallets are on the floor. Oh, maybe there are two mallets. So the hand hits the gong with one, then both mallets fall? Let me check the frames.

Frame 0.0: hand holding a mallet (wooden, two mallets? Wait, the mallets are shown as two in the later frames. Wait, the video shows: at the start, the hand is holding a mallet (maybe one), then in frame 2, the hand is no longer holding, and two mallets are on the carpet. So the hand strikes the gong (possibly using one mallet), then the mallets (both) fall. So the sequence is: hand moves towards gong, strikes it, then the mallets are dropped and lie on the carpet.

So the caption should be:

A hand holding a wooden mallet with a rounded head strikes a golden gong bearing black Chinese characters, mounted on a stand on a floral-patterned carpet. The hand then releases the mallets, which fall onto the carpet, leaving both mallets resting beside the gong. The gong remains stationary after the strike. The camera maintains a static perspective focused on the gong and the hand's motion.

Wait, but need to check minimal background. Background has a door, guitar, TV, but rule e says minimal unless essential. So maybe mention only necessary, like the gong's location (on carpet).

Also, rule f: exclude text recognition, so don't mention the Chinese characters. Wait, the gong has Chinese characters, but rule f says exclude text recognition. So even though they are visible, we can't mention them. So the gong is "golden" but don't describe the characters.

So revised: A hand holding a wooden mallet strikes a golden gong mounted on a stand on a floral-patterned carpet. The hand then releases the mallets, which fall onto the carpet. The gong remains stationary. The camera remains static, focusing on the gong and the hand

A hand holding drumsticks hits the gong, then the hand moves away and the drumsticks fall due to gravity.

The background (wall, carpet, guitar) is static and shows no fluid motion (fire, water, wind).


A shirtless man in beige pants performs a handstand on the floor of a living room, then transitions to a standing position and walks out of the frame. The camera remains stationary throughout.

A human subject performs a handstand, then transitions to standing and running across the frame, exhibiting discrete locomotion.

Background elements (walls, couch, curtains, framed pictures) remain static with no uniform shifting or fluid motion (fire, water, smoke, wind).


A person in a red shirt and gray shorts bends over a pile of assorted items on a concrete floor, handling a white plastic bag. They rise, holding the bag, and move toward the camera while a second person in a teal shirt and gray pants stands in the background. The camera tracks the first person with a slight shake, maintaining an elevated perspective as they walk.

Two individuals: one in a red shirt handling items from a pile (lifting, moving clothes), and another in blue standing and then walking away. Their movements are deliberate manipulations and locomotion due to physical forces.

The background (including furniture and walls) shows no uniform shifting or fluid motion. No fire, water, smoke, or wind is visible; the scene remains static except for minor camera adjustments.


A person wearing a dark green sleeve and light-colored pants uses a metallic tool on a wooden picture frame. The hands adjust the frame against a wall, then position the tool to secure a component to the frame’s corner. Subsequently, the hands align and attach a metal bracket to the frame’s side. The camera maintains a close-up, steady perspective focused on the hands and frame throughout the sequence.

A person's hands manipulating discrete solid objects: using a key to unlock a picture frame (0.5-2.5 seconds), unscrewing with a tool (2.6-4.5 seconds), and interacting with a door latch (5.0 seconds). Initial segments show tool manipulation on metal rings, wooden surfaces, and spring compression (0.0-0.4 seconds).

The background in the frame work segments (0.5-4.5 seconds) and door latch scene (5.0 seconds) shows static walls with no uniform shifting. The only fluid motion (water flow) appears in the top-right segment (0.0-0.4 seconds) but is limited to a small portion of the video and not dominant.


Initially, a person in a white shirt and patterned apron works at a large metal bowl outdoors. The scene shifts to two individuals: one in a white sleeveless shirt and another in a white shirt, who dip a white cloth into a black basin while one pours water from a blue container. The video concludes with a single person operating a wooden loom to weave fabric. The camera maintains close-up, static shots throughout the sequence.

Discrete objects: people moving (operating machinery, pouring/stirring liquids), which are solid and distinct.

Background elements (walls, ground) are static in each scene; liquid motion (water) is secondary to human actions, not dominant.


RAW CAPTION: Okay, let's tackle this video captioning task. The user wants a concise paragraph in chronological order focusing on the main subject's motion and behavior. First, I need to look at the video frames provided.

The video shows a woman in a gym doing an exercise. She's wearing a gray sports bra and black shorts with pink accents, along with gray sneakers and black socks. She's positioned between two weight rack posts, holding a barbell. Her stance is a lunge or split squat, with one leg forward and the other back. The camera seems to be moving slightly, maybe panning or following her movement.

I need to describe the sequence of her actions. In the frames, she's maintaining the lunge position, perhaps adjusting her posture. The gym background has other equipment like benches and weights, but according to the rules, background should be minimal unless essential. The main focus is her motion.

Check the rules: no text recognition, so ignore any text on her clothes. Mention appearance briefly—gray top, black shorts with pink, sneakers, socks. Spatial relationships: she's between the weight racks, legs in a lunge. Camera movement—maybe slight pan to the right or left. The user says to conclude with camera perspective and movement.

Let me structure it: start with her position, what she's doing (holding barbell, lunge), then any movement (maybe slight shifts), then camera. Keep it chronological. The video frames show her moving a bit, but since it's a short clip, maybe she's holding the position with slight adjustments.

Make sure to mention the number of subjects—only one person. Check if spatial relationships are needed: she's positioned between the two white weight rack posts. The camera's perspective seems to be at a medium shot, maybe following her movements slightly.

Avoid mentioning the background details unless essential. So just note the gym setting with equipment but not describe it in detail. The user says "minimal background descriptions."

Final caption should be concise. Let me draft:

A woman in a gray sports bra, black shorts with pink accents, and gray sneakers performs a lunge between two white weight rack posts, holding a barbell with both hands. She maintains a deep lunge position, shifting weight slightly between legs while keeping her torso upright. The camera remains steady at a medium angle, capturing her form from a slight left-side perspective.

Wait, check the rules again. Camera perspective and movement: "Conclude with the camera perspective and movement (e.g., top-down, pan left, slight shake)." The example says "slight shake" but the video description here—since the frames show her moving, maybe the camera is panning or moving a bit.

Wait, the user's sample output example (if any) isn't here, but the rules state to mention camera perspective and movement. In the provided video description, the frames might show the camera moving. Let's see the video description:

The user provided 5 frames, each showing the woman in the same position, but maybe the camera is panning slightly. The problem states to follow the rules. The user example in the task says: "Conclude with the camera perspective and movement (e.g., top-down, pan left, slight shake)."

So the caption needs to end with that. So in the example, if the camera is panning left, mention that. But in the given frames, perhaps the camera is moving to the right or left.

Looking at the frames: the description says the woman is between two weight rack posts. In the first frame, the weight rack is on the left, then in the next frames, the camera seems to shift right, showing more of the gym on the right. So the camera is panning to the right.

Wait, the user provided 5 frames. Let's check the movement. The first frame shows the woman with a weight rack on the left, then in the next frames, the weight rack on the left moves slightly out of frame, and more of the gym on the right is visible. So the camera is panning to the right.

Therefore, the camera movement is a slight pan to the right. So in the caption, the last part should say "The camera maintains a steady medium shot, panning slightly to the right."

Wait, but the user says "Conclude with the camera perspective and movement." So the last sentence should be about the camera.

Also, the main subject is doing a lunge, holding the barbell. The motion is maintaining the lunge with slight adjustments. The caption needs to be chronological: start with her position, then her actions (holding, shifting weight), then camera.

Let me draft:

A woman wearing a gray sports bra, black shorts with pink accents, and gray sneakers performs a lunge between two white weight rack posts, gripping a barbell with both hands. She holds the lunge position, shifting weight slightly between legs

A person is performing a lunge exercise with a barbell. The person and the barbell are the primary discrete objects moving.

No fire, water, smoke, or wind observed. Background elements (gym equipment, floor) appear stationary with no uniform shifting indicating camera motion.


A woman in a black shirt enters the frame from the right, approaches the gas stove, and adjusts a frying pan containing food while interacting with a large pot nearby. The camera remains stationary, capturing the kitchen setting throughout.

A person (solid object) moves into frame, interacts with the stove/pan (stirring, positioning), and gestures toward the camera. Hand movements and body positioning are tracked.

Static kitchen background (cabinets, microwave, countertop items) shows no uniform shifting. No dominant fire, water, smoke, or wind motion; the cooking flame in the pan is secondary to human action.


A person in a black shirt and black shorts jumps over a horizontal bar, lands on their back on a white mat, then pushes up to their knees and stands. A person in a red shirt runs toward them on the track. The camera remains stationary throughout.

Discrete objects include the high jumper (running, jumping, landing, and recovering from the sandpit) and secondary figures (e.g., person in red near the sandpit) exhibiting controlled locomotion due to physical forces.

The background (trees, buildings, track) shows no uniform shifting or fluid motion. No fire, water, smoke, or significant wind effects observed.


A person in a pink shirt and colorful headscarf moves a white box from the left to the right side of a kitchen counter, placing it next to various containers, then adjusts the position of the containers. The counter holds multiple food containers, measuring cups, and a baking sheet. The camera remains stationary.

The person (discrete solid object) is moving their hands and upper body, interacting with items on the counter (e.g., picking up a container, gesturing).

The kitchen background (cabinets, microwave, countertop) shows no shifting or fluid motion. No fire, water, or wind effects are present.


RAW CAPTION: Got it, let's tackle this video captioning task. First, I need to focus on the main subject, which is the excavator. Let's go through each frame.

In the first frame, the excavator is on a dirt field, with a yellow building in the background. The excavator is red and black, has a large bucket, and is moving forward. The second frame shows it continuing to move, the bucket is slightly raised. Third frame, it's still moving, the bucket is at a certain position. Fourth frame, the excavator moves closer, bucket is down a bit. Fifth frame, it's moving forward, maybe turning a bit.

Main subject: red and black excavator with a large bucket. It's moving across a dirt area. There's a person inside the cab, wearing red (but need to check if necessary; rule says mention appearance briefly, so maybe "a person in red" but not sure. Wait, rules say "briefly describe their appearance and number". The excavator is the main object, and there's a person in the cab. Let's see.

Chronological order: the excavator moves from left to right (or the camera might be following it). Wait, the video starts with the excavator on the left, then moves towards the right. The camera seems to be following the excavator's movement.

Looking at the frames: frame 0: excavator in middle, frame 1: moves left? Wait no, the sequence is from left to right. Wait, the first frame shows the excavator, then it moves towards the right side of the frame. Wait, the video is a sequence where the excavator is moving, so the camera is probably panning to follow it.

Wait, the frames show the excavator moving across the dirt ground. The background has a yellow building. The excavator is red with a black bucket. There's a person in the cab, wearing red clothing (maybe a jacket).

So, chronological order: the excavator moves forward (from left to right across the frame), the bucket is raised initially, then maybe dips slightly. The person in the cab is operating it.

Spatial relationships: the excavator is on a dirt field, with a yellow building in the background. The excavator's movement is across the ground, with the bucket oriented forward.

Camera perspective: the camera follows the excavator's movement, so it's a tracking shot, probably panning to the right as the excavator moves.

Now, putting it all together. Start with the excavator's motion. First, it's moving forward across a dirt lot. The excavator is red with a large black bucket. A person in red is operating it. The background has a yellow building. As it moves, the bucket remains raised, then maybe lowers slightly. The camera follows the excavator from the side, panning right.

Wait, rules say: chronological paragraph. So describe the motion step by step.

Let me outline:

- Initial position: excavator on dirt ground, near yellow building, bucket raised.
- Moves forward (direction: from left to right in the frame), the bucket is lowered slightly.
- Camera follows, panning right, keeping the excavator centered.

Wait, in the frames, the excavator starts on the left, moves to the right, so the camera is panning right to follow.

Appearance: red and black excavator, large bucket. Person in red inside the cab.

Background: yellow building in the distance, but minimal description.

So, the caption should mention the excavator's movement, its appearance, the person, and camera movement.

Let's check the rules:

a) Motion in chronological order: excavator moves forward, bucket lowers slightly.

b) Appearance: red and black excavator with large bucket, person in red.

c) Spatial: near yellow building (but minimal, so maybe "with a yellow building in the background" but rule e says minimal unless essential. Maybe just mention the background briefly.

d) Camera: follows the excavator, pans right.

e) Background minimal.

f) Exclude text, etc.

So drafting:

A red and black excavator with a large black bucket moves forward across a dirt lot, a person in red clothing operating it from inside the cab. The excavator maintains a forward trajectory, with the bucket gradually lowering as it progresses, while the camera pans right to follow its movement, keeping the machine centered against a backdrop of a yellow industrial building.

Wait, check if the bucket is lowering. In the frames, frame 0: bucket up, frame 1: bucket still up but moving, frame 2: maybe down a bit. Let's see the video: first frame, bucket is raised, then as it moves, the bucket is still up but the position changes. Wait, the description says "the excavator moves across the dirt ground", so the bucket might

Bulldozer moves forward and pivots, pushing a green container across the dirt ground. Dust clouds form from ground contact, indicating physical interaction with terrain.

Background elements (yellow building, ground, green container) remain stable without uniform shifting. No fire, water, smoke, or wind-driven fluid motion observed; dust is secondary to bulldozer interaction and not ambient.


A close-up shows a small metallic object on a light beige surface; a hand with a ring touches it. The scene shifts to a person with glasses applying a small dark spot to a bald head wearing a pearl necklace. Another individual in a light-colored shirt and tie appears in a separate shot. The person with glasses then leans in to kiss the bald head. The camera alternates between close-ups and medium shots, maintaining minimal background detail.

Discrete objects (hands and heads) are moving: a hand touching an object, a woman applying substance to a bald head, and a woman kissing the bald head.

The backgrounds in all scenes are static (no shifting or environmental motion). There are no fire, water, smoke, or wind effects.


A person in a green shirt, black pants, and white gloves pours liquid from a bottle into a green container, then into a white device positioned near a window. The camera shifts to focus on the device containing liquid, then pans down to show the device on the floor beside a yellow caution sign. The camera moves slightly downward to capture the device's base and surrounding floor area.

The person (in green shirt, white gloves) and the white bag are the primary discrete objects. The person moves their hands and body while interacting with table equipment, then steps away. The yellow box on the floor remains stationary.

The background (walls, window frames, floor) shows no uniform shifting. No dominant fluid or environmental motion (fire, water, smoke, wind) is present; the outdoor view through windows remains static relative to indoor elements.


A man in a red shirt, dark pants, white cap, and red shoes approaches a yellow chair with a blue dumbbell resting on it, picks up the dumbbell, steps to the side of the chair, and lowers himself into a lunge position. The camera remains stationary throughout.

A man (red shirt, white cap) moves across the scene; interacts with a yellow chair by picking up a blue ball and performing a leg stretch against it.

Static background (hedge and tiled ground) shows no uniform shifting; no fire, water, or wind motion observed.


RAW CAPTION: Got it, let's break this down. First, the video starts with a circular frame of a woman with long brown hair, wearing a green top, against a teal background. Then it transitions to her sectioning hair with clips. The next frame shows her from the back, still with the green top, hair down, and then she's clipping sections. Wait, need to follow chronological order.

First scene: circular frame, woman with long brown hair, green sweater, teal background. Then, she's shown in profile, putting hair up, with text "SECTION WITH CLIPS" but we have to exclude text recognition per rules. So focus on actions. Then split screen: left side close-up of her using a comb to section, right side back view. Then she's holding clips in her hands.

Wait, the video steps:

[0.0] - circular frame, woman with long brown hair, green top, teal background.

[1.4] - woman in profile, hands up sectioning hair, back to viewer.

[2.5] - same woman, back view, hands on hair.

[3.6] - split screen: left circle, woman front view combing; right, back view clipping.

[4.7] - woman from back, hands holding clips.

Need to describe in chronological order. Main subject is woman with long brown hair, green top. Actions: first, in circular frame (maybe a transition effect), then she sections hair with clips, showing profile and back views, split screen with combing and clipping, then holding clips.

Wait, the captions should be concise paragraph. Let's structure:

Starts with a circular frame showing a woman with long brown hair wearing a green top against a teal background. She then sections her hair using clips, first from a side profile as she lifts her hair, then from behind as she holds sections. In split-screen view, the left panel shows her front combing sections while the right panel displays her back securing hair with clips. Finally, she holds hair clips in her hands with the background remaining teal. Camera remains static with no significant movement.

Wait, but need to check rules. Exclude text recognition (so ignore "SECTION WITH CLIPS" text). Background is teal, but minimal descriptions. Focus on motion: she sections hair with clips, using clips to divide hair into sections, shows profile, back, split screen.

Let's check each frame:

Frame 0: circular frame of woman with long brown hair (green top), teal background.

Frame 1: she is in profile (side view), hands raising hair to section with clips.

Frame 2: back view, hands on hair (sectioning with clips).

Frame 3: split screen: left is her front view (circle) combing hair; right is back view (square) clipping sections.

Frame 4: back view, hands holding clips to secure sections.

So chronological order: starts with circular frame (woman in teal background, long brown hair, green top). Then she sections hair with clips from side view (profile), then back view. Then split screen shows front combing and back clipping. Finally, she holds clips with back view.

Need to write a paragraph describing this sequence.

Make sure to mention appearance: long brown hair, green top. Spatial relationships: back view vs front view. Camera perspective: static (since no mentioned movement).

So: A woman with long brown hair and a green top begins against a teal background in a circular frame. She sections her hair using clips, first in a side profile as she lifts her hair, then from behind as she holds sections. A split-screen view shows her front-combing sections on the left while securing hair with clips from the back on the right. Finally, she holds hair clips in her hands with a static camera focused on her back.

Wait, but need to be concise. Let's check for all rules.

a) Motion in order: starts with circular frame (maybe that's a visual effect, but the main subject is the woman in different views doing hair sections). Then she sections hair with clips (profile), then back view, split screen, then holding clips.

b) Appearance: long brown hair, green top, one woman.

c) Spatial: side profile, back view, split screen (left and right panels).

d) Camera: static (no movement mentioned).

e) Background: teal, minimal.

f) Exclude text.

So the caption:

A woman with long brown hair and a green top is shown in a circular frame against a teal background. She sections her hair with clips, first in a side profile lifting her hair, then from behind as she holds sections. A split-screen view displays her front-combing hair on the left and back-securing with clips on the right. Finally, she holds hair clips in her hands with a static camera angle.

Wait, but "static camera" is

A person (woman) is the primary discrete object. Her hair and hands move as she sections and clips her hair. Motion is explicit physical action (hand movements, hair manipulation) with clear bounding box tracking.

The background consists of digital patterns (stripes, hearts, diamonds) that transition between frames. There is no real environmental fluid motion (fire, water, smoke, wind) or natural environmental shifts. Pattern changes are due to video editing effects, not physical ambient phenomena.


Two toddlers, one in an orange and blue striped onesie and the other in a pink sparkly onesie, lie in a colorful ball pit filled with red, blue, green, and yellow balls. They hold and move the balls— the pink-clad child lifts an orange ball then a red one, while the striped child holds a red ball—smiling as they interact with the surroundings. The camera maintains a top-down perspective with slight movement, capturing their playful motion within the ball-filled space.

Two children (solid objects) are actively moving: bouncing, reaching for balls, and holding/displacing plastic balls. The balls are displaced by collisions with the children but are primarily stationary except for these interactions.

The background consists of colorful plastic balls in a ball pit; no fire, water, smoke, or wind is present. The balls are displaced by the children's movements but remain solid and discrete, not fluid. Static structural elements (like ball pit walls) are not visible, but the ball arrangement shows localized motion due to interactions rather than environmental fluidity.


A person’s dark-sleeved hand pours pale yellow batter from a clear glass measuring cup into a black frying pan on a gas stove, allowing the batter to spread evenly. A red silicone spatula then spreads the batter across the pan. The camera zooms in to focus on the pan as the batter cooks, with the stove’s burner grates visible beneath. Background elements include a red wall and kitchen countertop. The camera perspective shifts from a medium shot to close-up, capturing the pouring and spreading motion.

Discrete solid objects: person's hand (pouring batter), ladle (holding batter), pan (receiving batter), and spatula (spreading batter). These objects move due to human action.

Background elements (stove grates, wall) show no uniform shifting or environmental fluid motion; batter pouring is a controlled cooking action, not dominant ambient fluid dynamics.


A child in a dark blue coat with a hockey stick skates on a frozen surface, joined by an adult in a yellow jacket and another adult in a gray jacket with a red hat. The child moves forward, the yellow-clad person skates toward the child then shifts left, and the gray-clad individual follows from behind. They circle the ice, adjusting positions as the camera pans slightly to track their motion against a snowy, tree-lined background.

Three individuals (two adults, one child) moving via ice skating with hockey sticks, exhibiting locomotion driven by physical forces on ice.

Background elements (snowbanks, trees) show no uniform shifting; no fluid/environmental motion (fire, water, smoke, wind) present.


tags. No extra text.  Let me draft:  At the start, a line-drawn Hello Kitty stands on a white sheet with a row of colorful markers aligned vertically to its left. A hand enters from the right side of the frame, holding a pink marker, and moves toward the drawing.  Wait, the video starts with the drawing and markers, then the hand appears. So "at the start" is the first frame. Then the hand comes in.  Also, the markers are colorful, so "colored markers" or "various colored markers"?  The rule says "briefly describe appearance", so "a row of colorful markers".  Let me check the sample output format. The example given is just the tags with the caption.  So:  <caption_output>A line-drawn Hello Kitty stands on a white sheet with a row of colorful markers vertically aligned to its left. A hand enters from the right, holding a pink marker, and approaches the drawing. The camera maintains a static top-down perspective throughout.

A hand (discrete object) moves to color the bow on Hello Kitty's head using a pink marker.

The background is a static white paper with markers. No shifting backgrounds or fluid/environmental motions (fire, water, wind) detected.


A gloved hand holding a white cloth wipes a large gray industrial machine with vertical ridges, moving from left to right across its surface. The machine rests on a table against a perforated wall. The camera remains stationary, focusing on the cleaning motion.

A gloved hand moves in and out of the frame, interacting with the stationary metallic object (radiator), performing spraying and touching actions.

The background (perforated wall) is static with no shifting. No ambient environmental motion (fire, water, smoke, wind) detected.


A white SUV is parked. Two individuals are seated on a green bench; one wears a black shirt with a backpack. The second person, in a gray shirt, stands and walks toward the SUV's rear, opens the door, and enters. The camera follows this movement with a slight shake.

Discrete solid objects (people) moving: A shirtless man exits the SUV, another person handles a green container, and individuals walk around the vehicle. Motion is due to locomotion and physical interactions.

No shifting backgrounds or fluid/environmental motion (e.g., fire, water, wind) observed. Static background elements like the blue building, fence, and SUV remain stable across frames.


RAW CAPTION: Got it, let's tackle this. First, the video starts with a view of an indoor hallway. There are people walking. Let's check the sequence.

In the first frame, there's a person in a white shirt and dark pants running towards the camera? Wait, no, the camera moves. Wait, the first frame: a person in white shirt and dark pants (maybe running? But the camera is moving. Wait, the description says chronological order.

Looking at the frames: [0.0] shows a person in white shirt and dark pants moving, then [1.4] continues moving, [2.5] the camera pans to the left? Wait, the video is a series of frames. Let's parse each:

Frame 0: Hallway with people. A person in white shirt and dark pants (maybe running) is in the foreground. There are others in the background, like a person sitting, another standing.

Frame 1: The camera moves forward, following the person in white. The hallway has windows with shutters, green wall.

Frame 2: Camera continues moving, person in white is ahead, others in background.

Frame 3: Camera pans left, showing more of the hallway, the person in white is still moving.

Frame 4: Camera continues, the person in white is now further ahead.

Wait, the main subject is the person in white. They are moving through the hallway. Let's note:

- Person in white shirt and dark pants (medium size, moving forward)
- Other people: some sitting, some standing in the background.

The camera is moving along the hallway, following the person in white. The motion is a forward pan, maybe slightly shaky.

Background: hallway with green flooring, windows with shutters, ceiling lights.

Now, following rules:

a) Chronological motion: person in white moves through hallway, camera follows.

b) Appearance: white shirt, dark pants, medium size.

c) Spatial: in front of camera (initially), then as camera moves, person remains ahead.

d) Camera perspective: moving forward, tracking the person.

e) Background minimal: hallway, windows, lights.

f) Exclude text, names.

Now, structure the caption:

Start with the main subject's motion. At the start, a person in white shirt and dark pants is moving forward through a hallway. The camera follows this person as they walk, with other individuals (some seated, some standing) visible in the background. The camera moves forward, tracking the person, with slight movement and pan. Background elements like windows with shutters and ceiling lights are present but not detailed.

Wait, need concise. Let's check the frames:

0.0: Hallway, person in white shirt and dark pants (moving), others in background.

1.4: Camera continues forward, person still moving.

2.5: Person ahead, camera pan left.

3.6: More hallway, person still moving.

4.7: Camera continues.

So the main motion is the person in white moving through the hallway, camera following.

Now, write the caption:

The video shows a person in a white shirt and dark pants moving forward through an indoor hallway, followed by the camera as it tracks their motion. Other individuals are seated or standing in the background, with windows featuring shutters and ceiling lights visible. The camera maintains a forward-moving perspective, slightly shaky, tracking the person's progress down the corridor.

Wait, need to be more concise. Let's check length. The example output should be a paragraph.

Alternative: A person in a white shirt and dark pants walks forward through a hallway, with the camera following them closely. Other people are seated or standing in the background, and the camera moves forward, slightly shaky, while passing windows with shutters and overhead lights.

But the rules say "chronological paragraph".

Let's see:

In the initial frames, a person in a white shirt and dark pants walks through a narrow indoor hallway with green flooring, while the camera follows them. Other individuals are visible in the background, some seated and others standing. The camera moves forward, tracking the person, with slight movement and a pan to the left as the hallway curves. The background includes windows with shutters and overhead lighting, but these details are minimal.

Wait, the frames show the camera moving through the hallway, so maybe the person in white is moving, and the camera follows. Let's make sure the order is chronological.

0.0: Person in white shirt and dark pants is in the foreground, moving.

1.4: Camera moves forward, following them.

2.5: Camera pans left, person is ahead.

3.6: More of the hallway, person still moving.

4.7: Camera continues.

So the main subject's motion: person in white moves through the hallway, camera follows.

Now, final caption:

The video depicts a person in a white shirt

discrete_object_physics | ambient_environmental | camera_motion | ego_motion | static

Briefly describe what discrete, solid objects are moving.

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


A person in a light gray hoodie reaches toward a wooden box, retrieves a large white sheet with blue markings, and hands it to another individual in a camouflage uniform and hat, who receives it from the left. The camera remains close and slightly shaky throughout, capturing the transaction between the two figures against a dark background.

Two individuals (one in a white shirt, one in military uniform) interact by passing objects: the person in white holds and extends a blue item, then receives a metallic object from the seated military person. Hand movements and object transfers are discrete, solid motions due to explicit human action.

The background consists of a static dark blue wall and a wooden box on the floor. No fluid or environmental motion (fire, water, smoke, wind) is present. Background elements remain uniformly still throughout the clip.


RAW CAPTION: Okay, let's tackle this video caption. First, I need to understand what the user is asking for. They want a concise paragraph that describes the video in chronological order, focusing on the main subject's actions and movements.

Looking at the video frames provided. The main subject is a baby sitting in a high chair. The baby is bald, wearing a gray outfit with a white bib that has blue spots. Initially, the baby is holding their hand near their mouth. Then, in the next frames, an adult's hand comes into view from the right side, offering the baby a bottle or something similar. The baby looks at the hand and the object, then brings the object to their mouth. The background is a red wall with some posters or pictures on it, but the user said to keep background minimal, so maybe just mention the red wall briefly.

The camera seems to stay mostly stationary but there might be a slight movement. The user mentioned to exclude text recognition and named characters, so no names or text. Need to describe the baby's actions step by step. First, the baby is in the high chair, then the adult hand appears, offers the object, baby takes it. Spatial relationships: adult hand comes from the right. Camera perspective is probably a close-up, maybe a slight shake but not sure. The caption needs to be chronological, so order is important.

Check the rules again. Focus on motion and behavior of main subjects. Appearance: baby is bald, gray outfit, white bib with blue spots. Number: one baby, one adult hand. Spatial: adult hand from right. Background: red wall with posters, but minimal. Conclude with camera perspective. Maybe "static close-up with slight shake" but the user said to mention camera movement if relevant. The video seems to have a slight shake or movement, but maybe it's just the camera staying close.

Putting it all together. Start with the baby sitting in high chair, holding hand to mouth. Then adult hand enters from right, offers object. Baby takes object. Keep it concise. Avoid mentioning background unless essential. So background is minimal, so maybe just "red wall" as part of the setting.

Wait, the user says "keep background descriptions minimal unless essential for understanding motion." Here, the background might not be essential, but the red wall is part of the scene. However, maybe it's better to mention it briefly as "against a red wall" but only if needed. The main focus is the baby and the adult's hand. Since the baby is in a high chair, maybe "seated in a high chair" is important.

Let me draft:

"A bald baby wearing a gray outfit with a white bib and blue spots sits in a high chair against a red wall. The baby initially holds their hand to their mouth before an adult's hand enters from the right, offering a small object. The baby takes the object, bringing it to their mouth. The camera remains in a static close-up with slight movement."

Wait, the user said "conclude with camera perspective and movement." So the camera part needs to be included at the end. In the example, the video might have a slight shake, so "static close-up with slight shake."

Check the rules again: camera perspective and movement. So maybe "static close-up with slight shake."

But let me check the frames. The first few frames are the baby, then the hand comes in. The camera doesn't seem to move much, just maybe a slight shake. So "static close-up with minimal movement."

Wait, the user example in the problem statement says "top-down, pan left, slight shake" as examples. So if the camera is mostly still but with a slight shake, then "static close-up with slight shake."

Putting it all together.

"A bald baby wearing a gray outfit with a white bib and blue spots sits in a high chair against a red wall. The baby holds their hand near their mouth before an adult's hand enters from the right, offering a small object. The baby takes the object, bringing it to their mouth. The camera remains in a static close-up with slight shake."

Wait, but the user says "chronological paragraph describing the provided video." So maybe:

"Seated in a high chair, a bald baby wearing a gray outfit and white bib with blue spots initially holds their hand near their mouth. An adult hand then enters from the right, offering a small object, which the baby takes to their mouth. The camera maintains a static close-up with slight movement."

Check if "white bib with blue spots" is correct. In the video description, the bib is white with blue spots? The original frames mention "a white bib with blue spots." So yes.

Also, need to mention the baby's appearance: bald, gray outfit, bib details.

Is the adult hand the only other object? Yes. So "adult hand enters from the right."

Make sure to

A baby in a high chair interacts with a spoon held by a hand (likely an adult); the baby's hand moves toward the spoon, and the spoon is fed to the baby.

Background elements (red wall, decorations) show no uniform shifting, and there is no fire, water, smoke, or wind motion detected.


A girl in a white shirt and blue shorts runs toward a boy in a blue jersey with the number 14, who is positioned near a stone wall. The girl kicks an object, prompting the boy to run toward her; they then move together across the concrete driveway. The camera remains stationary, capturing the scene from a fixed position beside the stone wall.

Two children (a girl in pink and a boy in blue) are moving: they run and carry a large board across the driveway.

The background (stone wall, house, trees) is static throughout the video. No fluid or environmental motion is dominant.


A small child with light brown hair and a yellow shirt sits in front of an open red toy oven, reaching inside to pull out an object. The camera remains stationary with a slight shake, capturing the child's actions against a minimally visible background.

A child interacts with a red machine, moving hands, adjusting grip, and turning head—discrete solid object motion driven by intentional physical actions.

No shifting backgrounds or fluid/environmental motion (fire, water, smoke, wind); background elements (red machine, equipment) remain static and non-uniformly displaced.


A baby in a red shirt and white bib with yellow trim sits, clapping hands, while an adult in a red shirt interacts closely; the adult’s hand reaches toward the baby, who moves their arms and turns slightly. The scene occurs indoors near a window with blinds, with the camera maintaining a close perspective and slight shake.

The baby and adult are moving: baby's arms moving, bringing hands to mouth, and hugging; adult holding baby and hugging.

Background is static with no shifting or fluid motion (e.g., no fire, water, smoke, or wind).


A pair of hands manipulates a shiny red plastic sheet on a light-colored tiled floor, smoothing and adjusting its folds. The hands move the plastic sheet in front of a vertical slat radiator in the background. The camera remains stationary in a top-down perspective.

The hands of a person are manipulating a red plastic bag, causing the bag to deform and move. The hands and bag are solid, distinct objects with motion due to explicit physical forces (hand movements).

The background (window blinds and table surface) is static and not shifting. No fluid or environmental motion (fire, water, wind) is present.


A person in a bright green jacket and blue backpack stands on a rocky riverbank, watching a light brown dog splash in the water; the dog moves toward the shore while the person turns slightly to observe, then glances away. The camera pans slightly to follow the dog’s motion.

A dog swims through the river, exhibiting clear locomotion (swimming), while a person stands nearby observing the dog. Both are solid, distinct objects with identifiable motion.

The river surface shows minor ripples (ambient motion), but background elements (trees, riverbank) remain static without uniform shifting. No significant wind or fluid-dominated motion dominates the scene.


A woman in a black dress sits facing a man in a dark jacket holding paper, with a child in a pink shirt nearby. The man stands, moves toward the woman, and embraces her, lifting her slightly as they hug. The camera remains steady with no significant movement.

Two people (a man and a woman) exhibit distinct motion: the man stands up, walks toward the woman, and they engage in a hug. These actions involve locomotion and contact forces between solid objects.

The background elements (Christmas tree, wall paintings, furniture) show no significant shifting or fluid motion. No fire, water, smoke, or wind are present, ruling out ambient environmental motion.


A person lies on a bed covered by a colorful quilt featuring red, blue, and white patterns, partially visible. The camera pans around the bed, revealing the person’s arm and red objects on the bed surface, with slight camera shake.

A hand is interacting with small discrete objects (e.g., small items on the mosaic surface), moving them across the scene in a controlled manner.

The background (mosaic-patterned surface) shows no shifting or fluid motion; no fire, water, or smoke present. Static background elements (e.g., tiles) remain fixed without uniform displacement.


A person wearing a dark jacket and light pants stands in a room with a bookshelf and white cabinet in the background. They raise their right arm upward, then bring both hands together in front of their body, and subsequently raise their right arm again. The camera remains stationary throughout.

The man performs discrete actions: drinking from a bottle, handling a book, and writing on a whiteboard. These movements involve solid objects (person, bottle, book) undergoing explicit physical interactions (drinking, holding, writing).

No shifting background elements (bookshelf, whiteboard, wall) observed. No fire, water, smoke, or wind motion detected. Background remains static throughout the clip.


Two children sit on a purple and yellow playground swing, the child on the left wearing a blue shirt and red shorts while holding a purple object, and the child on the right wearing a yellow shirt and brown shorts while holding a small item. They sway back and forth on the swing, their movements synchronized. The camera follows their motion with a slight pan, capturing a grassy outdoor background behind the swing structure.

Two children seated on a slide; they are moving their hands and arms (one holding a toy, the other holding a teddy bear) as they interact with the objects.

Background elements (trees, fence) are static and show no significant motion; no fire, water, smoke, or wind dominates the scene.


A light brown, long-haired dog stands against a blue backdrop as a human hand gently pets its face, then moves to stroke its neck and back. The dog turns its head, opens its mouth slightly, and appears to lick its nose. The camera maintains a close-up perspective focused on the dog and the grooming hands, with minimal movement.

A person's hands are actively grooming the dog, moving across its fur; the dog exhibits minor head movements in response.

Background consists of a static blue fabric with no significant shifting or fluid/environmental motion (e.g., fire, water, wind).


A person in a blue shirt and red pants stands over a face-down individual lying on the gym floor, wearing black clothes and blue shoes. The standing person steps closer, bends down, and appears to check on the prone person. The background shows a weightlifting gym with other athletes and equipment. The camera remains stationary.

A person in blue shirt and red pants is moving (walking, bending) around a stationary person lying on the ground. Other people in the background are stationary or minimally moving.

No shifting background; no fire, water, smoke, or wind. Gym environment is static with fixed walls and equipment.


A baby with light blonde hair, wearing a brown hoodie, sits in a white high chair holding an orange spoon. An adult’s hand offers a white cup with a lid, which the baby takes and brings to their mouth. The baby then holds the spoon while the adult continues to support the cup. A green sippy cup rests on the wooden table in front of the high chair. The camera remains stationary, capturing the interaction from a fixed angle.

The baby in the high chair exhibits subtle movements (e.g., hand adjustments with the straw), and an adult's hand moves the cup towards the baby. These are solid objects interacting through physical forces (hand-to-cup transfer, baby’s grip).

The background features static furniture (chairs, tables) with no uniform shifting or fluid/environmental motion (no fire, water, wind).


RAW CAPTION: Got it, let's tackle this captioning task. First, I need to look at the video frames provided. The first frame shows a glass blender with chunks of avocado, maybe some green leaves (like basil?), and there's text saying "1 Cup Green Tea" but I have to exclude text recognition per rule f.

Then in the next frame (frame 2), a hand pours a liquid (probably the green tea) into the blender. The text "1 Cup Green Tea" is there, but again, rule f says to exclude text, so ignore that. Then frame 3 shows the blender with the tea poured in, and frame 4 has the word "Blend" on screen, but again, don't mention text. Then frame 5 shows a hand placing the lid on the blender.

So chronologically: Start with the blender containing avocado chunks and green leaves. Then a hand pours liquid into it. Then the hand puts the lid on. The main subjects are the blender (glass, with contents), the hand (pouring liquid, placing lid), the avocado chunks (green, cut into pieces), and the green leaves (small, maybe basil).

Spatial relationships: The blender is on a countertop (background, but rule e says minimal background unless essential. The countertop might be necessary to note the setting, but maybe keep it brief. The hand is above the blender when pouring and placing the lid.

Camera perspective: Top-down view for all frames, since it's looking straight down at the blender. No movement mentioned, so probably static top-down.

Let's structure it:

1. Initial state: Glass blender with chopped green avocado pieces and green leafy items.
2. Hand pours liquid into the blender.
3. Hand places the blender lid on top.
4. Camera remains top-down, showing the process.

Check rules: a) Motion in chronological order: pouring, then lid placement. b) Appearance: avocado (green, chopped), leaves (green), hand (human). c) Spatial: hand above blender during pouring and lid placement. d) Camera: top-down. e) Background minimal: countertop (but maybe mention "on a countertop" if necessary, but rule e says minimal. The video shows the blender on a striped mat, but maybe that's background. Wait, the first frame has a striped mat under the blender, so that's part of the background. But rule e says minimal unless essential. Maybe just note the blender on a surface.

Wait, the task says "background descriptions minimal unless essential for understanding motion". Since the motion is about the blender and hand, maybe the surface is not essential, but the fact that it's a counter is the context. Hmm. But maybe just say "on a surface" or "on a countertop".

Let me draft:

A glass blender containing chopped green avocado pieces and green leafy items sits on a surface. A hand pours a liquid into the blender, then places the blender lid on top. The camera maintains a top-down perspective throughout the sequence.

Check if text is excluded: yes, no mention of the text. Mention main subjects: blender, avocado pieces, leaves, hand. Motion: pouring, placing lid. Spatial: hand above blender. Camera: top-down.

Is "chopped green avocado" accurate? The video shows avocado chunks, so yes. Green leafy items (probably basil or similar). The liquid is poured in, which is the tea.

Wait, the avocado is yellow-green? Maybe just "green avocado pieces".

Also, check if the leaves are part of the ingredients. The first frame has avocado, leaves, then tea poured. So the sequence is: blender with avocado/leaves, hand pours tea, then lid placed.

Yes. So the caption should follow that order.

Now, make it concise:

A glass blender with chopped green avocado pieces and leafy greens sits on a surface. A hand pours a liquid into the blender, then secures the blender lid. The camera remains top-down.

Wait, "secures the lid" is part of the motion. Also, check if the hand is the main subject.

Another version:

Chopped green avocado pieces and leafy greens are in a glass blender. A hand pours a liquid into the blender, then places the lid on top. The camera provides a top-down view of the sequence.

Yes, that's chronological: initial contents, pouring, lid placement. Mention the hand's actions, the contents, and camera angle.

Check rules:

a) Motion in order: pouring, lid placement.

b) Appearance: avocado (chopped, green), greens (leafy), hand (human).

c) Spatial: hand above blender during pouring and lid placement.

d) Camera: top-down.

e) Background minimal: surface (countertop) mentioned as "on a surface" is minimal.

f) Excluded text: correct, no text mentioned.

Discrete objects: Green tea liquid poured into a glass bowl with avocado chunks; blender base spins to mix contents (causing rotational motion of ingredients within the glass bowl).

Static striped background (mat/surface) with no uniform shifting; no dominant fire, water, or smoke motion observed beyond transient liquid pouring (green tea), which is not ambient environmental.


RAW CAPTION: Got it, let's tackle this video caption. First, I need to break down each frame in chronological order.

Frame 0: Inside a bright salon. There are several people. A person in a red shirt is at a station, maybe doing a manicure. Another person in a black jacket is standing, a person in a pink shirt is walking, and others are around. The setting has white cabinets, mirrors, and a Christmas tree.

Frame 1: Exterior shot of the salon entrance. The building has graffiti, a sign above the door with a sun-like logo. The door is open, showing the interior.

Frame 2: Close-up of a person in a pink polo shirt (with a logo) working on someone's hand. The other person is in black, wearing a bracelet. They're at a table with manicure tools, a bowl of water, and a white device. Text "Via Lazzaro Pap 8" is there, but rule f says exclude text recognition, so ignore that.

Frame 3: A wider shot of the salon interior. More people: a woman in red is at a station, a woman in black is sitting, others are in the background. The room has chairs, tables, and the Christmas tree is visible.

Now, need to describe in chronological order, focusing on motion and behavior.

Start with frame 0: Inside salon, multiple people. A person in red shirt (likely client) sits at a table; another in black jacket stands, a person in pink shirt walks through. Then cut to exterior (frame 1): building with graffiti, salon entrance. Then frame 2: close-up of hands being manicured by pink-shirted person, other person in black assisting. Then frame 3: wider interior shot, people in various positions.

Need to mention spatial relationships. For example, in frame 0, the person in red is at a table, the person in black is standing nearby, pink-shirted is walking.

Check rules: exclude text, named characters, stylistic analysis. So no mention of "Via Lazzaro Pap 8", just describe the scene.

Outline:

- First scene: interior salon. A seated person in red shirt at a station; standing person in black jacket; person in pink shirt walking. Others in background.
- Then exterior: building facade with graffiti and salon entrance.
- Close-up: manicurist in pink polo (logo) working on another person's hand (in black, wearing bracelet); tools on table.
- Final scene: wider salon interior showing multiple people (client in red, others seated/standing), Christmas tree visible.

Make it concise, chronological.

Let's draft:

The video opens in a bright salon interior where a person in a red shirt sits at a station, while another in a black jacket stands nearby and a person in a pink shirt walks through the room. The camera then cuts to an exterior view of the salon’s entrance, framed by a building with graffiti. Next, a close-up shows a manicurist in a pink polo shirt working on another person’s hand, which is held by someone wearing a bracelet. The scene transitions to a wider interior shot with multiple people, including a seated client in red, others interacting, and a Christmas tree in the background.

Wait, check the order of frames: 0, 1, 2, 3. So frame 0 (salon interior), frame 1 (exterior), frame 2 (close-up manicure), frame 3 (wider salon).

So chronological:

1. Interior salon: person in red seated at station; person in black jacket standing; person in pink walking.
2. Exterior: salon entrance with graffiti.
3. Close-up manicure: pink-shirted person (logo) on another’s hand; tools on table.
4. Wider salon: multiple people, Christmas tree.

Now, check rules: focus on motion and behavior. In frame 0, people are in different positions (seated, standing, walking). Frame 1 is static exterior. Frame 2 is close-up of hands (manicurist working). Frame 3 is people interacting in the salon.

Also, mention spatial relationships: in frame 0, the person in pink is walking through the room, the seated person in red is at a station (so in front of the station), the standing person in black is near them.

But need to be concise. Let's try:

The video begins inside a salon where a person in a red shirt sits at a station, another in a black jacket stands nearby, and a person in a pink shirt walks through the room. The camera shifts to an exterior view of the salon entrance, framed by a building with graffiti. It then focuses on a close-up of a person in a pink polo shirt working on another’s hand

Discrete objects (people) are moving: in the interior scenes, people are walking and performing procedures (e.g., a woman in red shirt manipulating a hand).

The background in both interior and exterior scenes is static (no shifting walls or ground). There are no fluid/environmental motions (e.g., fire, water, smoke, wind) observed.


A person's lower face with red lipstick appears against a blue and white checkered background; they bring a white tissue to their mouth. The scene shifts to a close-up of a hand with multiple rings on the fingers, orange-tinted skin, holding or touching a white tissue. The camera maintains close-up perspective, moving from the face to the hand with minimal spatial shifts. Background remains minimal and checkered.

A hand with rings is moving toward the mouth, performing an explicit physical action (likely wiping or touching the mouth).

No shifting backgrounds or fluid/environmental motion (fire, water, wind) observed; background elements appear static with no uniform movement.


A person's hands adjust an orange cable near a black pipe on a light-colored carpet, shifting the cable's position, then pressing down on the carpet with both hands while maintaining contact with the pipe, captured from a top-down perspective showing the hands' movements against the carpeted floor.

A person's hands are actively pressing and smoothing a carpeted surface, with deliberate motion indicating physical interaction with the object.

Background elements (floor, wall, and static objects) show no uniform shifting; no fluid environmental motion (e.g., fire, water, wind) is present.


A person in a white chef’s coat with black stripes stands at a black countertop, using a knife to slice food on a blue plate. Another individual in a white shirt enters from the left, assisting with a blue plate while the first person continues cutting. The background includes a white bathtub and greenery; the camera remains static with minimal movement.

A person is moving hands and body while handling objects (blue tray) on a countertop; discrete solid motion from human locomotion.

Background elements (countertop, walls) show no uniform shifting; no fire, water, or smoke detected, so ambient environmental motion is absent.


A person in a teal shirt with a black backpack embraces another person in a light pink top and black pants. They separate, the pink-top individual covers their face with hands, then laughs and claps, while the teal-shirted person gestures with both hands. The camera maintains a steady eye-level perspective throughout the interaction, capturing their movements against a plain beige wall and a brown door in the background.

Two people are moving: the person in teal turns to face the person in white, who adjusts her hair and then both engage in conversation with hand gestures.

The background (wall and door) is static and shows no shifting. No fire, water, smoke, or wind motion observed.


The video opens with a black screen, then transitions to an indoor room where a person in a bright yellow suit executes a dynamic dance move, spinning in place while facing the camera. Two individuals in dark suits approach from behind; one steps forward toward the yellow-clad dancer, while the other remains slightly behind. The camera remains stationary throughout, capturing the scene from a fixed medium distance with minimal background details visible.

Two people (one in yellow, one in black) are moving and interacting, exhibiting locomotion (walking, stepping, turning).

No shifting background elements or fluid/environmental motion (fire, water, wind). Background walls and painting remain fixed.


A child in a white karate uniform with a green belt approaches an adult in a blue uniform holding a black belt; the child extends their arm to take the belt, then turns left and moves away while the adult steps back. The child’s uniform has visible white belts on the table behind them, and a South Korean flag is mounted on the wall. The camera pans left to follow the child’s movement.

Briefly describe what discrete, solid objects are moving.

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


In a martial arts dojo, a man in a red uniform with a black belt adjusts the hands of a small girl in a gray shirt. He guides her hands upward, then shifts his own hands to demonstrate a motion, while the girl follows his lead and adjusts her stance. Other children practice in the background. The camera remains steady, capturing the interaction from a frontal perspective.

The instructor and child (in red and gray uniforms) are moving their hands and bodies in a coordinated manner, demonstrating a martial arts technique. Their motion is due to explicit physical forces (the instructor guiding the child).

The background (walls, floor, other children) remains stable with no uniform shifting. No fluid or environmental motion (fire, water, smoke, wind) is present.


A large man in a black shirt and beige shorts, with red knee sleeves, lifts a barbell while squatting in a gym rack. Spotters in dark shirts stand on both sides, assisting by gripping the barbell and adjusting its position. The man begins in a wide stance, lifts the barbell upward, and the spotters shift their grips as he completes the lift. The camera remains stationary, capturing the action from a frontal perspective with minimal background detail.

The central person is performing a weightlifting motion, with clear discrete movement of limbs and torso against the barbell; spotters adjust positions around the lifter.

Background elements (metal gym equipment, walls) show no uniform shifting or fluid motion; no fire, water, or smoke present.


RAW CAPTION: Got it, let's tackle this caption. First, the video shows a boy doing a handstand. He's wearing blue shorts and gray pants, shirtless initially. Then he flips down, stands up, and the shirt is now on. Wait, the sequence: starts with handstand, then he does a flip to land on his feet, then he's standing, adjusting his shirt. Let's break it down chronologically.

Frame 0: Boy in handstand, back against wall, legs up, arms supporting. Pants are gray, shorts blue. Wall is tiled.

Frame 1-2: He's still in handstand, maybe moving a bit. Then in frame 2, he starts to flip down.

Frame 3: He's in mid-flip, now standing on feet, shirt off? Wait no, the next frame shows him standing, then he has a blue shirt. Wait, the shirt is blue and white, and he's adjusting it. Wait the video: first he's shirtless (wearing blue shorts and gray pants), then he does a handstand, flips down, stands up, and then he's holding the blue shirt (maybe it was on him but fell off? Or he had it on). Wait the description: "boy in blue shorts and gray pants, shirtless" then after flipping, he's holding the blue shirt. Wait no, in the frames, the first part he's shirtless, then in the later frames, he's wearing the blue shirt. Wait the video: starts with handstand (shirtless), then he flips down, stands up, and then he's wearing the shirt. Wait the description says "boy in blue shorts, gray pants, shirtless" initially. Then when he stands up, he's holding the shirt? Wait the last frame shows him holding the shirt. Let's check the frames:

Frame 0: Handstand, shirtless, blue shorts, gray pants.

Frame 1: Still handstand, maybe moving.

Frame 2: Flipping down, arms down, body moving.

Frame 3: Now standing on feet, shirt off? Wait no, the next frame (frame 4) he's holding the shirt. Wait the description: "frame 3: standing, frame 4: holding shirt, frame 5: adjusting shirt, frame 6: same." Wait the video shows the boy doing a handstand, then flipping to stand up, then he's holding the shirt (maybe it fell off during the flip), and then he adjusts it.

So chronological:

1. The boy is in a handstand against a tiled wall, shirtless, wearing blue shorts and gray pants. He supports himself with hands on the ground, legs raised.

2. He flips downward, transitioning from the handstand to a standing position.

3. After landing, he stands upright, now wearing a blue shirt, and holds it at his waist, adjusting it.

Now, spatial relationships: the wall is behind him. Background is the tiled wall. Camera is stationary, maybe a slight shake but not moving much. Background minimal.

So the caption should be:

A shirtless boy in blue shorts and gray pants performs a handstand against a tiled wall, then flips down to stand upright, wearing a blue sleeveless shirt, holding and adjusting it. The camera remains stationary with a slight shake, capturing the motion against the wall.

Wait check the rules: "Focus primarily on motion and behavior in chronological order. Briefly describe appearance and number. Mention spatial relationships if relevant. Conclude with camera perspective."

Number is one boy.

Appearance: starts shirtless (blue shorts, gray pants), then after flip, he's wearing blue sleeveless shirt (the shirt is blue, maybe with white stripes?).

Wait the shirt is blue sleeveless, maybe with a design. But exclude text recognition, so "blue sleeveless shirt" is okay.

Motion: handstand → flip down → stand, adjust shirt.

Spatial: against tiled wall.

Camera: stationary, slight shake.

So putting it all together.

Let's check each part:

- Chronological: handstand, flip, stand, adjust shirt.

- Appearance: initially shirtless, blue shorts, gray pants; later blue sleeveless shirt.

- Spatial: wall behind.

- Camera: stationary, slight shake.

Yes.

So the caption:

A shirtless boy in blue shorts and gray pants performs a handstand against a tiled wall, then flips down to stand upright while wearing a blue sleeveless shirt, holding and adjusting it. The camera remains stationary with a slight shake, capturing the motion against the wall.

Wait but the rules say "exclude text recognition, named characters, or stylistic analysis." So the shirt is blue sleeveless, that's okay.

Also, "Keep background descriptions minimal unless essential for understanding motion." The wall is essential here.

Okay, that should be it.

A boy in a blue tank top and gray pants performs a handstand transition to standing, exhibiting controlled locomotion and limb movements.

Gray tiled wall and concrete ground remain static throughout the frames with no visible shifting or fluid motion (fire, water, smoke, wind).


A right hand adjusts light-colored Scrabble tiles on a yellow surface, moving them from right to left to reorganize their arrangement. The hand shifts multiple tiles across the surface, altering their positions while the tiles remain in a linear sequence. Background objects are blurred but visible. The camera maintains a top-down perspective with slight movement as the hand operates.

A hand is moving Scrabble tiles (A, B, O, A, W, S, R) on a table. The tiles are being rearranged by the hand.

No shifting background or fluid/environmental motion observed. Background elements (lemon slice, decorative object) remain stationary throughout the clip.


A person in a white and black striped shirt stands behind a wooden table with a red basket containing rolled items on skewers, a plate with donuts, and a small jam bowl. They pick up a skewered item, bring it to their mouth, and eat. The camera shifts to a close-up of the person eating before returning to the wider shot of the person at the table.

The woman's hand and the corn dog exhibit discrete motion as she brings the corn dog to her mouth and eats it, with visible positional changes.

Background elements (kitchen wall, shelves, decorations) show no uniform shifting or fluid environmental motion (e.g., no fire, water, wind).


A group of children in red, blue, and black clothing gather around a black-and-white soccer ball on a concrete surface. A child in a blue jacket and dark pants with white stripes leans forward to kick the ball, which rolls toward the right. Other children, including one in a red jacket and another in a black shirt with green shoes, shift positions and observe the ball’s movement. The camera remains in a top-down perspective with slight shake, capturing the children’s interactions from above.

Children (in red, blue, black) and a ball are moving. The ball is kicked by the child in blue, causing it to move in a circular pattern.

The background (concrete ground and wall) is static and not shifting. No environmental fluid motion (fire, water, smoke, wind) is present.


A person in a red shirt and dark jeans stands beside a large gray concrete block outdoors. They bend down, lift a wooden piece from the block, and hold it upright. The background includes a brick wall and greenery. The camera maintains a top-down view throughout.

A person is performing actions: opening a box, lifting a cardboard box, and holding a bottle. The person's motion is due to their own physical actions (bending, lifting, walking).

No shifting background elements; no fire, water, smoke, or wind detected. Background (building, trees, stone structure) remains static.


A person in a red tank top and blue jeans stands in front of another individual whose bare feet rest on a surface. The person in red grasps the feet, then manipulates them with both hands, moving the feet slightly. The background shows a dirt path and vegetation. Camera is static, positioned at the level of the feet.

A person (wearing red top and blue shorts) is using their hands to manipulate the feet of another person (who is seated with feet extended). The hands are moving in a purposeful manner, indicating intentional action.

The background (dirt road and greenery) is stable with no significant fluid or environmental motion. Greenery appears static, no wind or water visible.


A baby seated in a car seat with a gray mesh strap across their shoulder looks directly at the camera, their head slightly tilted. A green object is introduced from the left side of the frame, moving closer to the baby's face before being withdrawn. The baby turns their head left as the object approaches, maintaining focus on the item. The camera remains close and slightly shaky, capturing the baby’s upper body against the car seat’s fabric background.

Baby exhibits minimal head movements and eye blinks; plush toy shifts slightly with baby's movements.

No shifting background or fluid/environmental motion (fire, water, wind); car seat and interior remain stationary.


RAW CAPTION: Got it, let's break down the video. First, the main subject is a person wearing a red cap and a yellow sleeveless shirt. They're holding an iron. The video starts with them using the iron on a purple garment. Then, they move the iron away, and in the next frames, they're holding a frying pan. Wait, no—wait, the second frame shows them holding the iron near their face, then they take it away, and then hold a frying pan. Let's check the sequence.

Frame 0: Person with red cap, yellow shirt, using iron on purple fabric.
Frame 1: Close-up of iron near face, maybe touching something.
Frame 2: Person moves iron away, still holding it.
Frame 3: They hold the iron up, then maybe a frying pan? Wait, the next frames: frame 3 shows them holding a frying pan. Let's see the order.

Chronologically: Start with ironing (iron on fabric), then they lift the iron, bring it close to face (maybe making a face), then move it, then hold the frying pan. Wait, the captions need to be in order.

Appearance: red cap, yellow sleeveless shirt. The person is moving the iron, then the frying pan. Spatial: the iron is on the fabric, then they hold it up. Camera movement: seems to be handheld, maybe a bit shaky. Background: minimal, just a room with some items.

So steps:

1. Person in red cap and yellow shirt uses an iron on a purple garment.
2. Lifts the iron, brings it near their face.
3. Replaces the iron with a frying pan, holding it up.

Wait, frame 0: iron on fabric. Frame 1: close-up of iron near face. Frame 2: person holding iron. Frame 3: holding frying pan. Wait, the frames are:

0: iron on fabric (purple, maybe jeans), person in red cap, yellow shirt.

1: close-up of iron near face (they're holding it up).

2: person moves back, holding the iron, then maybe a frying pan? Wait, frame 2: they have the iron, then frame 3: holding a frying pan.

Wait, let's look again. The video sequence:

- First frame: person with red cap, yellow shirt, ironing a purple garment.

- Second frame: close-up of iron near face (maybe touching something, then they move it).

- Third frame: person holding the iron away from face.

- Fourth frame: person holding a frying pan, showing it to the camera.

Wait, the frames are 0 to 4 (as per the user's example: [0.0], [1.4], etc.). Let's parse the provided frames:

Frame 0: [0.0] - Person in red cap, yellow sleeveless shirt, using an iron on purple fabric (like pants or a shirt).

Frame 1: [1.4] - Close-up of the iron near their face, perhaps they're bringing it close to their face.

Frame 2: [2.5] - Person moves the iron away, showing it, then maybe a frying pan? Wait, the next frame: frame 2.5 shows them holding the iron, but then frame 3.5 shows them with a frying pan.

Wait, the user provided 5 frames: 0.0, 1.4, 2.5, 3.6, 4.7.

Let's list each:

- 0.0: Person wearing red cap, yellow sleeveless shirt, ironing a purple garment (likely clothes) with an iron.

- 1.4: Close-up of the iron near their face (they're holding it close to their face, maybe making a gesture).

- 2.5: Person moves the iron away, then holds it up (still holding the iron).

- 3.6: Person now holding a frying pan, presenting it to the camera.

- 4.7: Person still holding the frying pan, possibly moving it.

Wait, but the frames might be showing the sequence: ironing → close-up of iron near face → holding iron → holding frying pan.

Now, the caption needs to be chronological. So:

A person wearing a red cap and yellow sleeveless shirt is ironing a purple garment. They lift the iron towards their face, then hold the iron up. Subsequently, they hold up a frying pan and display it to the camera.

Check the rules:

a) Motion: ironing, lifting iron to face, holding iron, then holding frying pan.

b) Appearance: red cap, yellow sleeveless shirt, purple garment (but maybe not essential, but the main subject's appearance).

c) Spatial: iron on garment

The person (wearing a red cap and yellow shirt) is moving their body and arms, holding a white sneaker and a metal pan. The sneaker and pan are being manipulated by the person's hands.

The background (wall and framed picture) is static and there is no fluid/environmental motion (e.g., fire, water, wind).


A group of people in white uniforms with belts stand together; a person in a white uniform with a brown belt moves toward the center and kneels, followed by others in white uniforms who kneel and bow. The camera, with a slight shake, tracks the central figure’s motion.

Discrete solid objects (people) are moving: a central figure performs martial arts motions while others converge, kneel, or adjust positions.

Static background elements (walls, floor) show no uniform shifting; no fire, water, smoke, or wind visible in the scene.


The video opens with a top-down view of rocky, uneven dirt ground, where a foot in a dark shoe is visible. It then transitions to a medium shot of a person wearing a brown jacket, dark pants, and a cap, using a wooden shovel to dig into the soil. The individual repeatedly lifts and plunges the shovel into the dirt, moving the tool back and forth. The scene is set against a backdrop of dry grass and leafy bushes. The camera shifts from a top-down perspective to a focused medium shot of the person’s digging motion.

A person is actively raking leaves, moving the rake in a repetitive motion to gather leaves into a pile. The leaves are displaced by the rake's motion, but the rake itself is the primary moving object.

The background (trees and grass) is static with no significant shifting. There is minimal leaf movement due to wind, but it is not dominant and not fluid motion.


A baby wearing a white shirt with a design, brown pants, and red shoes starts crouched on the carpeted floor. The baby then stands and moves forward, crawling or taking steps toward the camera, passing a beige couch on the left and a fireplace with a large vase on the right. The camera remains stationary with a slight shake throughout.

The baby is moving by crawling and sitting. A colorful ball rolls into the frame and is pushed by the baby.

Background elements (couch, plant, fireplace) are stable and show no fluid/environmental motion. The baby's movement is not causing background shifting.


A person wearing a gray shirt holds a yellow and black shaver near their face, lifts it to their mouth, then lowers the shaver and moves their head downward. The background features a shower curtain with blue, green, and white squares. The camera remains stationary.

The man (solid object) is drinking from a bottle and making hand gestures (holding head, touching face). The bottle is a distinct moving object due to his actions. Both are solid, trackable subjects with clear motion.

The bathroom background (shower curtain, walls) is static with no shifting elements, fluid motion (fire/water/smoke), or wind-induced movement. No ambient environmental features are present.


RAW CAPTION: Got it, let's break down the video. First, the person is packing a suitcase on a bed. The suitcase is brown and black, open, with clothes and items inside. They close the suitcase, then place a tablet and a book on top. Then they pick up some clothes and put them into a smaller bag. The text in the video is about items, but we need to ignore text recognition. Let's structure the chronology:

1. Person closes the suitcase (after arranging items inside).
2. Places tablet and book on top of the closed suitcase.
3. Picks up a white item (clothes) and puts them into a hand luggage (smaller bag).
4. Camera is top-down, static? The video shows the bed, so top-down view.

Check rules: focus on motions, chronological order. Main subject is the person (in blue shirt, maybe), but we don't mention clothing color unless essential. Wait, rule b says briefly describe appearance and number. The person's shirt is blue, but maybe it's optional. The suitcase is brown and black, open then closed. The tablet and book are placed on top. Then clothes are moved to a hand luggage.

So step by step:

- A person closes a brown and black suitcase on a bed, then places a tablet and a book on top. Next, they pick up a white garment and place it into a hand luggage.

Camera perspective: top-down view, no movement mentioned.

Avoid text, so no "livro + tablet" etc.

Let's draft:

A person in a blue shirt closes a brown and black rolling suitcase on a bed, then places a tablet and a book on top of it. They then pick up a white garment from the bed and place it into a hand luggage. The camera maintains a top-down perspective throughout.

Wait, rule c: mention spatial relationships. The suitcase is on the bed, tablet and book are on top of the suitcase. Clothes are on the bed (since the person picks up from bed).

Also, the first frame: the suitcase is open, filled with items. Then they close it. So:

In the video, a person closes a brown and black rolling suitcase on a bed, then places a tablet and a book on top of the closed suitcase. Subsequently, they pick up a white clothing item from the bed and transfer it into a hand luggage placed next to the bed. The camera remains stationary in a top-down position.

Check if we need to mention the bed is covered with a light blue quilt. But rule e says minimal background unless essential. The bed is the main background, but maybe not essential. The suitcase is on the bed, so maybe "on a bed" is okay.

Wait, the first action: person closes suitcase (which was open). Then places tablet and book on top. Then moves clothes into hand luggage.

So chronological order:

1. Person closes the open brown and black suitcase on the bed.
2. Places a tablet and a book on top of the closed suitcase.
3. Picks up a white garment from the bed and puts it into a hand luggage.

Camera is top-down, no movement.

Now, check if we need to mention the hand luggage. The text says "roupas na bagagem de mão" which is clothes in hand luggage. So the action is transferring clothes to hand luggage.

Also, the person's actions: hands, so maybe describe the person's actions as hands closing suitcase, placing items, etc. But rule a says "motion and behavior of main subjects (people/animals/objects)" — the person is the main subject.

Wait, the output should be concise, so:

A person closes a brown and black suitcase on a bed, then places a tablet and a book on top of it. Next, they pick up white clothing and put it into a hand luggage. The camera stays top-down throughout.

But let's see if we need to specify the number of items. Tablet and book: two items. Clothing: white garment (singular).

Also, the first frame: suitcase is open with clothes inside. Then closing. So "closes an open brown and black suitcase".

Putting it all together:

A person closes an open brown and black suitcase on a bed, places a tablet and book on top, then transfers a white garment into a hand luggage. The camera remains in a top-down perspective.

Check all rules:

a) Motion chronological: closing suitcase, placing items, transferring clothes.

b) Appearance: suitcase is brown/black, tablet/book, white garment, hand luggage.

c) Spatial: suitcase on bed, tablet/book on top, garment picked up from bed.

d) Camera: top-down.

e) Background minimal: bed mentioned, but it's necessary to know where the suitcase is.

f) Exclude text, so no "livro + tablet" etc.

Yes, that works.
</think>

Person's hands and luggage items (e.g., books, clothes) undergo deliberate, discrete motions during packing (e.g., inserting items into the suitcase, zipping it).

No shifting background elements (bed, pillows, room furniture remain static); no fire, water, smoke, or wind present.


A man in a white shirt, black shorts, and white shoes runs toward the camera on a green field. He slows to a stop, extends his legs into a wide lunge with arms raised, then steps laterally into a side lunge while maintaining balance. The camera remains stationary, capturing the sequence from a frontal view.

A single human subject performs running, stretching, and kicking movements—distinct solid objects (person) moving due to locomotion and physical actions.

The background (yellow wall and green floor) shows no uniform shifting; no fire, water, smoke, or wind motion present.


A person in a black-and-white striped hoodie and dark pants raises their arms upward while moving right across a snowy slope, accompanied by a blonde individual in a blue jacket walking left beside them. A third person in red is visible in the background. The camera tracks the striped hoodie person with slight movement.

A person in a striped jacket adjusts their hat and camera while taking photos; a person in a blue hoodie stands and shifts position; a person in red remains stationary; and a person in dark clothing crouches and stands.

The background consists of a static building wall and trees with minimal wind-induced sway. No fire, water, or significant smoke is visible; ambient motion is negligible and not dominant.


Three individuals stand on a blue trampoline in a wooded area: a person in a blue shirt (left), a person in a white hoodie (center), and a person in a white t-shirt with jeans (right). Initially, they face each other; the person in blue extends their arm toward the person in the white hoodie, who steps backward and moves left, then the person in the white t-shirt steps back to the right. The person in the white hoodie eventually moves to the left side of the trampoline, leaving the other two standing near the center. The camera remains static, capturing the scene from a direct frontal perspective with minimal background detail.

Three people are interacting on a trampoline, exhibiting clear motion due to jumping, collisions, and locomotion. The trampoline itself is a solid object moving with the people's actions.

The background features static trees with no uniform shifting or fluid motion (e.g., fire, water, wind). There is no evidence of ambient environmental motion dominating the scene.


A shirtless man in dark shorts stands on a sunlit grassy field between two trees. He begins jumping rope, swinging it in wide circular motions around his body as he jumps. The camera remains static throughout the sequence.

A person is hula hooping, with the hula hoop moving in a circular pattern around the person's waist. The person's body is moving with the motion of the hoop.

Background elements (trees, grass) are static with no significant fluid/environmental motion (no fire, water, smoke, or wind effects).


A man in a black shirt and black shorts with red trim stands in a plaza, then begins jumping rope. He swings the rope over his head and under his feet rhythmically as pedestrians walk and a scooter passes by near an ornate building and trees. The camera remains stationary, capturing the action from a frontal perspective.

A man is walking towards the camera, and other people are present in the background but are not the primary moving object.

The background (buildings, trees) is stationary and shows no uniform shifting. There are no fire, water, smoke, or wind effects dominating the scene.


A person in a white shirt with a dark Nike logo stands in a room with a chandelier in the background. A hand from the right holds a small white object with red dots near the person's face, then retracts. The hand returns, holding the object closer to the camera, displaying it before moving it away. The person maintains a neutral posture throughout. The camera remains in a close-up, slightly shaky perspective.

The boy manipulates a small solid object (appears to be a ball or toy) with his hands. An off-screen hand enters the frame to interact with the boy's head before retracting.

Background elements (wall, chandelier) remain stationary with no shifting. No fluid or environmental motion (fire, water, wind) detected.


Two robed figures face each other on a grassy field beside an aqueduct. The dark-robed figure (helmeted, carrying a sword) advances toward the white-robed figure (helmeted, cloak with a cross emblem), who steps backward. The dark-robed figure lunges with the sword, prompting the white-robed figure to counter by grappling the attacker. The camera maintains a steady medium shot, tracking their interaction as they engage in combat.

Two distinct human figures (one in dark robes, one in white robes) are moving across the frame; their locomotion appears to be walking, with visible shifts in position relative to the background.

The background elements (arches, hills, and grass) remain consistent in position across frames, showing no signs of fluid/environmental motion (fire, water, smoke, wind).


A woman with long dark hair wearing a red top initially faces right, then turns her head left while smiling and raises her right hand to her chest. She remains seated against a dim, blurred background with faint lights. The camera maintains a close-up perspective with slight handheld movement.

A woman in a red dress moves her head and body (turning, smiling), and holds a small dog which she brings to her face. Both exhibit solid, distinct motion from deliberate physical actions.

Background shows consistent, blurred lights and structures with no shifting elements; no fire, water, smoke, or wind visible. Background remains static throughout.


A person in a gray shirt, black shorts, and yellow-green shoes sits on the floor in a room with a door to the left and a bed with a blue blanket in the background. They rise to a standing position, facing the camera while keeping the same attire. The camera remains static at a low angle throughout.

A person (discrete solid object) is moving by standing up and adjusting shoes.

Background elements (door, window, bed) are static. No fluid/environmental motions (fire, water, smoke, wind) detected.


A man in a blue plaid shirt and dark pants walks toward a group of dogs on a concrete surface, bending down to interact with them near a stone wall and stacked items. Another man in a light blue shirt and dark pants then approaches, also bending to examine the dogs. The camera follows the subjects with slight shake and handheld movement.

Two people (one in a blue striped shirt, one in a light blue shirt) and a dog interact. The people move around, bending, walking, and handling the dog, which is being restrained or moved on the ground.

The stone wall, ground, and static background elements (e.g., buckets, plants) show no uniform shifting. No fire, water, smoke, or wind-driven motion is visible.


tags. Let's make sure it's concise. Let's see the video: the person's legs are moving, so "steps forward" is correct. The background is minimal, so mention "building with windows and grass" briefly. Camera perspective: low angle, following movement. The video's camera is following the person's motion, so "follows the person’s movement" or "tracks the person’s steps".  Let me structure it:   "A person in white pants, black shoes, and white socks walks forward on a reddish-brown surface, taking alternating steps. In the background, a building with windows and green grass is visible. The camera maintains a low-angle perspective, tracking the person’s movement with slight shake."  Wait, the video's camera movement—does it shake? The user says "slight shake" as per rule d. But maybe the video is steady. But the example in the problem doesn't specify. Let's see the frames: the video is a bit blurry, maybe the camera is moving slightly. But the rules say "describe camera perspective and movement", so if it's following the movement, "tracks" or "follows".   Also, the main subject is one person. So "A person... walks forward..."  Let me check all rules:  a) Motion: person walking, steps. Chronological: first frame shows legs, then moving forward.  b) Appearance: white pants, black shoes, white socks.  c) Spatial: background building and grass.  d) Camera: low angle, follows movement (or tracks steps).  e) Background minimal: building and grass mentioned briefly.  f) No text, names, etc.  Okay, let's write the caption.  <caption_output>A person wearing white pants, black shoes, and white socks walks forward on a reddish-brown surface, taking alternating steps. A building with windows and green grass appears in the background. The camera maintains a low-angle perspective, tracking the person's movement with minimal shake.

A person (baseball pitcher) in white pants and dark shoes performs a repetitive pitching motion, including leg lifts and stepping, representing discrete object movement due to physical locomotion.

Background elements (building, grass) are static and show no uniform shifting or fluid motion (no fire, water, smoke, or wind effects). Grass and building remain fixed relative to the ground.
