A person wearing glasses and a white shirt holds a silver flute horizontally to their lips, moving fingers over the keys while playing; the flute is positioned in front of a keyboard, with a white door visible in the background. The camera remains static, capturing the subject from a frontal perspective.

The person's hands and the flute exhibit discrete movement: fingers press keys and move across the instrument, demonstrating intentional locomotion for playing the flute. No other objects show significant motion.

The background (door, wall, table) is static with no shifting or environmental fluid motion (no fire, water, smoke, or wind). Background elements remain fixed throughout the clip.


A brown hand with visible fingers presses black and white piano keys, moving sequentially from right to left across the keyboard surface. The hand’s motion shifts across multiple keys, maintaining contact with the keys throughout the sequence. The camera remains fixed in a top-down perspective, capturing the hand’s interaction with the keyboard without any movement or shift in angle.

A human hand is moving across the piano keys, pressing individual keys in a deliberate sequence. This represents a discrete solid object (hand) exhibiting controlled motion due to physical interaction with the piano.

The piano keyboard and surrounding elements show no shifting background or fluid/environmental motion (fire, water, wind, etc.). The static background remains consistent throughout the video.


A person in dark snow gear and a helmet snowboards down a slope, arms initially outstretched. They turn, lifting their right leg high in a kicking motion, then resume gliding with arms extended. Other skiers are visible in the background, with a building appearing later. The camera follows the snowboarder, exhibiting slight shake.

Multiple skiers (foreground and background) moving down slope via locomotion. Primary subject performs dynamic maneuvers (leg lift, turns) due to muscle-driven forces and gravity.

Static snow-covered mountains, trees, and lodge are visible. No dominant fluid/environmental motion (fire, water, smoke, wind) observed; snow appears stable with no billowing or flow.


A man in a red sleeveless shirt and gray shorts lifts a barbell loaded with weights overhead, extends his legs into a lunge position, then steps back while maintaining the barbell above his head. The background includes gym equipment such as weight racks and benches. The camera remains stationary throughout.

A person (wearing red shirt and gray shorts) and a barbell are the discrete objects. The person performs a weightlifting motion: lifting the barbell from the ground to the shoulders, then overhead in a clean-and-jerk sequence. The barbell moves in discrete, controlled increments due to the lifter's physical force.

The background (gym walls, equipment racks, and floor markings) shows no shifting or environmental fluid motion (no fire, water, smoke, or wind). Background elements remain stationary and consistent throughout the clip.


RAW CAPTION: Got it, let's tackle this video captioning task. First, I need to look at the video frames. The video shows a baseball field with two people. In the first frame, there are two figures: one might be a pitcher and another a batter or runner? Wait, no, the video has a baseball field with dirt and grass. Let's check the actions.

Looking at the frames: frame 0 has two people. Then frame 1, one person runs towards the other. Frame 2, maybe the pitcher throws, and the runner is moving? Wait, the video shows a baseball game. Let's see the movement. The first frame: two players on the field. Then in the next frames, one player (maybe the pitcher) throws the ball, and the other (batter or runner) moves. Wait, the video starts with two people, then one moves towards the other. Let's track the action.

First, the scene is a baseball field. There are two players. One is on the pitcher's mound or near the base? Wait, the field has a dirt infield and grass outfield. The two people: one is running towards the other. Let's see the movement. From frame 0 to 1: the person on the left (maybe the pitcher) is throwing, and the person on the right (batter) is running. Wait, in frame 0, the person on the left is in a throwing motion, and the right person is in a running position. Then in subsequent frames, they move.

Wait, the video is a sequence where one player (smaller, maybe pitcher) throws the ball, and the other (larger? Or just a player) runs. Let's check the chronological order. The main subjects: two people. In the first frame, the left person is throwing (arm extended), right person is running. Then as the video progresses, the left person continues the motion, maybe the ball is in the air, and the right person moves towards the direction of the throw.

Wait, the frames show: [0] two people, one on left (pitcher) in throwing pose, one on right (batter) running. Then [1], the pitcher has released the ball, batter is moving. [2], pitcher is follow-through, batter continues. [3], the pitcher is still moving, batter is near the base. Wait, the video is a baseball game where the pitcher throws the ball towards the batter, who is running (maybe a base runner). Wait, but in a typical game, the pitcher throws to home plate, batter hits, but here maybe it's a different scenario.

Wait, the key is to describe motion in chronological order. Let's list the steps:

1. Initially, two individuals are on the baseball field. One is positioned on the left (pitcher, likely smaller in size, wearing light clothing), the other on the right (batter/runner, larger, same light clothing).
2. The pitcher on the left throws the ball towards the batter/runner on the right.
3. The batter/runner on the right begins moving towards the direction of the throw (likely running to first base or another base).
4. The pitcher completes the throwing motion, and the batter/runner continues their run.

Now, spatial relationships: the pitcher is on the left, batter on the right, with the field in between. The camera is stationary, looking from the infield towards the outfield (since the dirt is in the foreground, grass behind). Wait, the camera perspective: the video shows the field with the dirt infield in the bottom part, grass outfield, so the camera is at a low angle, looking towards the field. No camera movement mentioned—probably static.

Background: minimal, just trees and light poles. So describe the motion chronologically.

Let's structure:

"Two individuals are visible on a baseball field: a smaller person on the left (pitcher) and a larger person on the right (batter). The pitcher throws a ball towards the batter, who begins running towards the direction of the throw. As the pitcher completes their motion, the batter continues their run across the field. The camera remains static, capturing the scene from a low angle perspective."

Check rules:

a) Motion and behavior in order: pitcher throws, batter runs. Yes.

b) Appearance and number: two people, pitcher smaller, batter larger. Yes.

c) Spatial: pitcher left, batter right. Yes.

d) Camera: static, low angle. Yes.

e) Background minimal: trees, poles, but not emphasized. Yes.

f) No text, characters. Yes.

Now, make it concise. Let's draft:

In a baseball field, a smaller person on the left throws a ball towards a larger person on the right, who begins running in the direction of the throw. As the throw concludes

Players are moving on the field (running, walking) due to locomotion.

The background (trees, light poles) is stationary with no fluid motion (fire, water, wind).


RAW CAPTION: Got it, let's break this down. First, the video starts with a person standing in front of a sign that says "Art's Cyclery SLO". The person is wearing a black hoodie with the store's name on it. Then, the scene cuts to a close-up of a bicycle frame, specifically the chainstay area. Next, hands (wearing a watch and a yellow wristband) are seen adjusting or working on the bicycle's component, like the chain or derailleur. The hands move the component, probably fixing or adjusting it. Now, I need to make sure the caption is chronological, focuses on motion, descriptions of appearance, spatial relationships, and camera perspective.

Start with the first scene: a person in a black hoodie standing in front of a sign. Then the camera shifts to a close-up of the bike frame. Then hands appear to adjust the bike part. Mention the hands' appearance: one with a watch, one with a yellow wristband. The bike is gray with a blue logo. The background in the first scene is the store, but minimal. In the bike part, the background is blurred, maybe a workshop. Camera moves from wide shot of person to close-up of bike, then close-up of hands working. So chronological order: scene 1 (person), scene 2 (bike frame close-up), scene 3 (hands adjusting).

Check rules: focus on motion and behavior. Main subjects are person (static, then camera moves), then bike frame, then hands working. Descriptions: person in black hoodie, bike frame gray with blue logo, hands with watch and yellow wristband. Spatial: in first scene, person in front of sign; then camera moves to bike, hands working on the frame.

Avoid text recognition (like the website), named characters. So no "Art's Cyclery" in the caption, just the store's sign but maybe omit? Wait, rule f says exclude text recognition. So the sign's text shouldn't be mentioned. But the store's name is part of the background. Wait, the instruction says "Exclude text recognition, named characters, or stylistic analysis." So if the text is part of the scene, but since it's background, maybe just say "a store sign" without the text. But in the first frame, the person is in front of a sign that has "Art's Cyclery SLO". But rule f says exclude text recognition, so don't mention "Art's Cyclery", just the sign.

Wait, the example says "Exclude text recognition", so the sign's text (Art's Cyclery, SLO, website) shouldn't be in the caption. So describe the scene as "a person in a black hoodie standing in front of a store sign". Then the next scene is a close-up of a bicycle frame, then hands working on it.

So putting it all together: The video opens with a person wearing a black hoodie standing in front of a store sign. The camera then transitions to a close-up of a gray bicycle frame with a blue logo, where a pair of hands (one with a watch and a yellow wristband) adjusts a component near the chain. The camera remains focused on the hands and the frame during the adjustment.

Check if it's chronological: first person, then bike frame, then hands working. Motion: person is standing (static), then camera moves to close-up of bike, hands move to adjust. Descriptions: black hoodie, gray bike frame with blue logo, hands with watch and yellow wristband. Spatial: person in front of sign; hands working on the frame. Camera perspective: starts with a medium shot, then close-up.

Make sure it's concise. Let's rephrase:

A person in a black hoodie stands in front of a store sign. The scene cuts to a close-up of a gray bicycle frame with a blue logo, where a pair of hands (one wearing a watch and a yellow wristband) adjusts a component near the chain. The camera remains focused on the hands and the frame during the adjustment.

Check rules: a) motion and behavior chronologically: person standing (static), then camera cuts to bike frame, hands adjusting. b) appearance: black hoodie, gray frame, blue logo, hands with watch and yellow wristband. c) spatial: person in front of sign, hands on bike frame. d) camera perspective: starts with medium shot, cuts to close-up, remains focused. e) background minimal (store sign mentioned, but it's part of the scene, maybe okay). f) exclude text recognition: no mention of "Art's Cyclery", so good.

Yes, that works.
</think>

<caption_output>A person in a black hoodie stands in front of a store sign. The scene cuts to a close-up of a gray bicycle frame with a blue logo, where a pair of hands (one wearing a watch and a yellow wristband

A person's hands (discrete solid objects) are moving to manipulate a bicycle frame. The motion is due to explicit physical forces applied by the hands.

No shifting background elements observed. No fire, water, smoke, or wind present.


A hand holding a blue paintbrush applies a horizontal blue stripe to a white sheet of paper taped with pink striped tape. The hand moves the brush left to right, then right to left, blending the blue paint. The camera maintains a static top-down perspective throughout.

A hand holding a paintbrush is moving across the paper, applying blue paint in a horizontal stripe. The hand is a discrete solid object with clear physical motion.

The background elements (paper, tape, surface) show no uniform shifting or fluid motion; the paper remains stationary relative to the frame.


In an indoor basketball court, several players in dark uniforms move and dribble a basketball. Initially, players are positioned across the court; as the video progresses, one player dribbles the ball while others run toward or away from it, maintaining spatial distribution on the court. The camera remains stationary, capturing the motion from a fixed position.

Discrete solid objects (people) are actively moving: basketball players dribbling, running, and shooting the ball, with visible locomotion and physical interactions (e.g., ball handling, player positioning).

Background elements (walls, gym structure, court lines) remain static across frames with no uniform shifting, and there are no fluid/environmental motions (fire, water, smoke, wind) present.


A person wearing a dark shirt uses a yellow pencil to fill out an open worksheet, with their left hand holding a blue pen near the pages. The worksheet rests on a dark table, with white cables visible to the left. The camera maintains a static top-down perspective throughout the sequence.

A person's hand is moving to write in a book. The pen is being held and moved across the page. This is a discrete, solid object motion due to the person's physical action of writing.

The background (wall and table) is static and unchanging. No fire, water, smoke, or wind is visible. Therefore, no ambient environmental motion.


A person in a yellow shirt and dark pants lies on grass, initially motionless, then moves their arms and shifts position slightly. The background includes grass and nearby bushes, viewed from a top-down perspective with slight camera shake.

A person (discrete solid object) is moving their arms, head, and body, indicating active locomotion and gestures.

The background consists of grass and bushes with no dominant environmental motion (e.g., no wind, water, fire). The background is relatively static.


A person wearing a black beanie and a white hoodie with black patterns sits on a wooden deck. They drink from a green hose while holding a clear cup, then exhale a puff of smoke. After placing the hose on the deck, they use their hand to interact with a white container holding orange liquid. The camera remains steady with slight movement.

A person is performing discrete actions: smoking a pipe (involving hand movements to inhale/exhale), eating, and manipulating objects (e.g., pipe, possibly a food item). The person's hands and body movements are explicit physical actions.

Background elements (house, fence, plants) show no uniform shifting, indicating no significant camera-induced motion. No dominant fluid or gaseous motion (e.g., fire, water, smoke) dominates the scene; smoke from the pipe is minimal and not the primary focus.


A light-skinned hand holds a white spray bottle with a metallic nozzle on the right side of the frame against a dark background, pressing the nozzle to release a fine mist. The camera remains stationary, focusing on the hand and bottle without movement.

A hand holding a spray bottle is moving in a discrete manner to dispense liquid, with the hand's motion being the primary physical action.

The background is a uniform solid black, showing no shifting or fluid motion. While a spray of liquid is visible, the dominant motion is not dominated by fire, water, or wind (which would trigger ambient_environmental per the Ambient Rule).


An individual wearing a light straw hat, white shirt, and dark apron handles a knife and raw meat, adjusting their grip while standing near a metal fence. They move to place the meat on a wooden cutting board, positioning it carefully. The camera follows the subject’s actions with a slight pan, capturing the preparation process against a backdrop of parked cars and greenery.

A person wearing an apron and hat is manipulating a tool (likely a brush or pen) on a surface, with hand movements being the primary discrete object motion.

Background elements (fence, cars, trees) show no uniform shifting; no fire, water, smoke, or wind motion detected.


A young girl in a red vest and white shirt moves toward a taller man wearing a black t-shirt with a design. She reaches out to him as he drinks from a glass. The camera pans from the girl to the man, capturing shelves in the background with minimal detail.

A child in a red vest extends their arm to place an object on a shelf, then interacts with an adult. The adult (in black shirt) reaches for the object and later drinks from a cup. Both individuals move as solid objects due to explicit physical interactions (reaching, grasping, drinking).

The background (shelves, walls, and interior decor) shows minimal movement; no fluid or gaseous motion (fire, water, smoke, wind) is present. Background elements appear static relative to the scene.


A child with short dark hair and a white shirt speaks directly to the camera, making slight head movements as they present information while positioned in front of shelves holding various items; the camera remains stationary, maintaining a steady close-up focus on the child's upper body and face.

The child (a discrete solid object) is moving: speaking with slight head and hand movements.

The background (shelves and window) is stationary. No fire, water, smoke, or wind is present.


A pair of hands, one adorned with a purple bracelet, manipulates a red thread using a yellow tool. The left hand holds the thread steady while the right hand loops the thread around the tool, pulling it to form a stitch. The hands move in coordinated motions, with the red thread wrapping around the yellow tool. The background includes a red tray with miscellaneous items, but the focus remains on the hands. The camera maintains a close-up, stable view throughout.

Hands manipulating a red string with a yellow tool (likely a crochet hook) in a stationary setting; the hands and tool are the moving discrete objects.

No shifting background elements; no fire, water, smoke, or wind observed.


A seated woman in black attire on a blue mat sits up, reaches for a dumbbell held by a standing woman wearing a black jacket with fur trim, light gray pants, and black-and-white sneakers, then lifts the dumbbell upward while the standing woman assists. The background includes blue walls and gym equipment. The camera remains static.

Two people: one lying on a mat performing physical exertion (e.g., push-up motion), the other standing and assisting. Their movements are solid, distinct actions driven by physical exertion.

The background (blue wall, gym equipment, floor) shows no uniform shifting or fluid/environmental motion (fire, water, wind); all static elements remain consistent across frames.


RAW CAPTION: Got it, let's break this down. The video shows a person rappelling down a tree. First, the person is high up on the tree, attached to a rope. Then they start descending. The main subject is a single person, probably wearing some gear for rappelling. The background is trees and blue sky, but we need to keep background minimal. The motion is the person moving down the tree along the rope. The camera is probably stationary, looking up at the tree. Let's check the rules: chronological order, describe motion, appearance (maybe just "person" since no color details given), spatial relationships (the person is on the tree, rope attached), camera perspective. The video starts with the person at the top, then they move down. So the caption should say the person descends from the tree via rope, maybe their position relative to the tree. Camera is static, looking up. Let's draft:

A person wearing climbing gear descends a tall pine tree along a rope, moving downward from the canopy toward the ground. The individual is positioned against the tree trunk, with the rope extending upward. The camera remains stationary, capturing the descent from a low angle against a clear blue sky.

Wait, but need to be concise. Let's make it shorter. Check the rules: chronological, motion, appearance (single person, maybe "a person" without color), spatial (on tree, rope), camera perspective.

First frame: person at the top, then moving down. So "A single person, equipped with rappelling gear, descends a tall pine tree along a rope, moving downward from the upper canopy toward the base of the tree. The camera maintains a static, upward-facing angle, observing the descent against a clear blue sky."

Wait, but the rules say "briefly describe appearance and number". So "a person" (since color not specified, just number). Motion: descending. Number: one. Background minimal: blue sky is minimal. Spatial: on the tree, rope attached.

Let me check the example. The user's example: "A person wearing climbing gear descends a tall pine tree along a rope, moving downward from the canopy toward the ground. The individual is positioned against the tree trunk, with the rope extending upward. The camera remains stationary, capturing the descent from a low angle against a clear blue sky."

But need to be concise. Maybe: "A person descends a pine tree via rope, moving downward from the upper branches toward the ground. The individual is suspended by the rope, positioned against the tree trunk. The camera remains static, observing the descent against a clear blue sky."

Wait, the video is 0.0 to 5.0 seconds, so the person starts at the top (frame 0) and moves down. So "A person, suspended by a rope, descends a tall pine tree from the canopy toward the ground. The individual remains attached to the rope, moving downward along the tree trunk. The camera is stationary, capturing the descent from a low angle against a clear blue sky."

But check the rules: "Exclude text recognition, named characters, or stylistic analysis." So no mentioning of "rappelling" or specific gear unless necessary. But "suspended by rope" is okay. Let's make it concise.

Final draft: A single person descends a tall pine tree along a rope, moving downward from the upper branches toward the ground. The individual is positioned against the tree trunk, with the rope extending upward. The camera remains stationary, observing the descent against a clear blue sky.

Wait, but need to be concise. Maybe: "A person, suspended by a rope, descends a pine tree from the canopy toward the ground. The individual moves downward along the tree trunk, with the rope visible extending upward. The camera is stationary, capturing the descent against a clear blue sky."

Yes, that's good. Check all rules:

a) Motion: descends, moving downward.

b) Appearance: single person.

c) Spatial: against tree trunk, rope extending up.

d) Camera: stationary, capturing descent.

e) Background: clear blue sky (minimal, as it's essential for understanding motion? Maybe, since it's a clear sky, but the rule says minimal unless essential. It is part of the scene, but maybe the focus is on the action. Maybe the sky is not essential, but the video is outdoors, so maybe keep it minimal. Wait, the background is trees and sky, but the rule says "minimal unless essential". So maybe "against a clear sky" but the main is the tree.

Wait, the user's example says "against a clear blue sky", so it's allowed.

Putting it all together: The person starts at the top, then moves down. So chronological: starts at the upper branches, then descends. So "A person begins descending a pine tree from the upper branches

A person (solid object) is descending from a tree via a rope. The motion is due to gravity and the rope, representing discrete object physics.

The background consists of stationary trees and a clear sky with no significant fluid motion (fire, water, smoke) or strong wind-induced motion. The background does not shift uniformly, indicating no camera motion.


A pair of hands with light skin manipulates light brown mannequin hair, initially guiding a section of the braid toward the back of the head. The hands then gather additional strands, interweave them into the existing braid, and secure the new section with small metallic hair pins. The mannequin’s head remains stationary against a dark backdrop, while the hands move fluidly to adjust the braid’s structure. The camera maintains a close-up, static angle focused on the hair and hands throughout the sequence.

Discrete objects: hands actively braiding hair; hair strands being manipulated by explicit physical forces from the hands.

Static dark background (wall) with no shifting or environmental motion; no fire, water, smoke, or wind present.


A person in a dark hoodie and camouflage pants, wearing a beanie, stands in a snowy field and turns toward a small child in a red jacket standing at a distance. The person extends their arm and throws a red object toward the child, who remains stationary. The camera captures the action from a static ground-level angle with slight handheld movement.

A person (in black coat and camouflage pants) is walking and throwing an object. A small dog is running in the snowy field.

The background (trees and snow-covered ground) is static. No significant ambient environmental motion (e.g., wind-blown snow, fire, water) is observed.


A person in dark clothing shovels snow from a snow-covered street, moving toward a driveway. They continue clearing the driveway, with the camera transitioning from a close-up to a blurred frame, then to a wider view showing the person working amidst residential houses and snow-laden trees. The camera perspective shifts from close to distant, capturing the person's motion across the snowy landscape.

A person is shoveling snow and walking across the driveway, moving from right to left and then to the center.

The background (fence, trees, houses) is stationary and shows no shifting or fluid motion. No significant ambient environmental motion (like wind or water) is dominant.


A man in dark athletic wear and black shoes lifts a barbell with blue and green weight plates overhead in a squat position, then stands up and releases the barbell, which falls to the platform. The background includes wooden boxes and a plain wall. The camera remains static throughout.

A person (discrete solid object) lifts a barbell from a squat position to overhead, stands, drops it, and then repositions it. The barbell's movement is driven by the person's physical force.

The background (wooden crates and wall) remains static; no shifting background or fluid/environmental motion (fire, water, smoke, wind) observed.


RAW CAPTION: Got it, let's break down the video. First, the main subject is a man in a dark shirt and blue jeans. The video starts with him standing in front of a backdrop of white and gold curtains, maybe some red too. Then he steps onto a black platform. Wait, the sequence: [0.0] he's standing, [1.4] he moves, maybe the camera shifts to his legs? Wait, the frames: first frame he's standing, then in frame 1.4 he's walking towards the platform, then frame 2.5 he's stepping onto the black platform. Then he's on it, and starts stepping, like moving on the platform.

So chronological order: the man (dark shirt, blue jeans) begins standing in front of draped curtains (white, gold, red). Then he walks forward towards a black platform. He steps onto the platform, then begins to step back and forth on it. The camera starts with a medium shot of him standing, then follows his movement down to focus on his lower body as he interacts with the platform. Background is the curtains, but minimal description. Camera movement: starts at waist level, then shifts down to focus on his feet and the platform, so probably a slight downward tilt. No text, no named characters.

So structure: describe his actions step by step, appearance, spatial relationships (platform in front of him initially, then he steps onto it), camera perspective (starts medium, then focuses on lower body/feet).

Let me draft:

A man in a dark t-shirt and blue jeans stands facing the camera in front of draped white and gold curtains with a red section. He walks forward and steps onto a black platform, then begins stepping back and forth on the platform. The camera initially captures him from the waist down as he approaches the platform, then focuses on his feet and the platform surface. Background includes the draped curtains, which remain static throughout.

Wait, check rules: b) briefly describe appearance and number. He's one person, dark shirt, blue jeans. c) spatial relationships: platform is in front of him (he steps onto it), so he moves towards the platform. d) camera perspective: starts with a shot of his upper body, then shifts to waist down to feet (so maybe a downward tilt). Wait, the first frame is him standing, then the camera angle changes to show his legs stepping onto the platform. So camera movement: the camera focuses on his lower body as he interacts with the platform.

So revised:

A man wearing a dark t-shirt and blue jeans stands facing the camera before a backdrop of draped white, gold, and red curtains. He walks forward, steps onto a black platform, and then steps back and forth on it. The camera initially shows him from the waist up but shifts downward to focus on his feet and the platform. The background curtains remain static.

Wait, check rules: e) keep background descriptions minimal. So maybe just "draped curtains" instead of colors. The background is curtains, which are part of the setting.

Let me check the frames again:

Frame 0: man standing, full body, facing camera.

Frame 1.4: he's moving, probably walking towards the camera (since next frame he's stepping onto platform). Wait, the second frame (1.4s) says "a man in a dark shirt, blue jeans walks forward". Then 2.5s: legs on platform, then 3-4s: stepping on the platform.

So the order: man stands, then walks forward (toward the platform), steps onto platform, then steps back and forth.

Camera: starts with a medium shot (waist up), then the camera moves down to focus on his lower body as he steps onto the platform, so the camera's perspective shifts downward.

So the caption should be:

A man in a dark t-shirt and blue jeans stands facing the camera in front of draped curtains. He walks forward, steps onto a black platform, and begins stepping back and forth on it. The camera starts with a medium shot of the man but shifts downward to focus on his feet and the platform. The background curtains remain static.

Check rules:

a) motion and behavior in chronological order: standing → walking forward → stepping onto platform → stepping on platform.

b) appearance: dark t-shirt, blue jeans, one person.

c) spatial: platform in front of him (he steps onto it), curtains behind.

d) camera perspective: medium shot then shifts down to feet.

e) background minimal: draped curtains.

f) no text, names.

So that's the caption.
</think>

<caption_output>A man wearing a dark t-shirt and blue jeans stands facing the camera before draped curtains. He walks forward, steps onto a black platform, and begins stepping back and forth on it. The camera starts with a medium shot of the man but shifts downward

A person in a black shirt and jeans is moving on a black platform; their legs and feet are shown in motion, indicating intentional locomotion (stepping, lifting, walking).

The background consists of static curtains and a floor with no shifting, fluid, or environmental motion (e.g., no fire, water, smoke, or wind).


A person wearing a blue Nike shirt and blue headphones sits behind a drum set, holding drumsticks. They begin by positioning the sticks in front, then swing them to strike the drums and cymbals. The drum set features multiple cymbals and drums surrounding the seated individual. The camera captures the scene from a static top-down perspective.

The drummer (person) and drumsticks exhibit discrete motion: the drummer's arms/hands move to strike the drums, causing the drumsticks to swing and impact the drumheads. These solid objects move due to explicit physical forces (muscle movement and collision).

The background (drums, room walls, floor) is static with no shifting or environmental elements like fire, water, smoke, or wind. All background features remain fixed throughout the clip.


A shirtless, muscular wrestler in red pants with white stripes holds a wrestler in dark trunks by the waist; a referee stands to the left. The shirtless wrestler lifts the opponent and forcefully slams him onto the mat. The camera remains steady with slight shake, capturing the ring ropes and crowd in the background.

Two wrestlers (one in red pants, one in black trunks) engage in physical combat: the red-pants wrestler is lifted, thrown, and pinned to the mat by the black-trunks wrestler. Both exhibit solid, distinct motion due to explicit physical forces (grappling, throws).

The background elements (wrestling ring ropes, arena walls, and distant spectators) remain largely static with no uniform shifting or fluid/environmental motion (e.g., fire, water, smoke).


A person in a blue jacket and red shirt sits before dark blue curtains, playing a large brown cello. Their left hand moves along the fingerboard while the right hand draws the bow across the strings in a continuous motion. The camera remains static with a slight shake throughout.

Cellist (person) and cello (solid object) exhibit discrete motion: cellist sways rhythmically while bowing, with cello held firmly but showing subtle vibrations from playing.

Dark curtains form a static background with no fluid motion, smoke, or wind effects observed; background elements remain uniformly fixed.


A group of men in a room with pink walls: one man in dark clothing and light jeans bends over a seated individual, then crouches as he interacts with them, while others shift positions (some sit, others stand) near the doorway. The camera remains static throughout.

Multiple people (discrete solid objects) are engaged in physical interactions (e.g., grappling, shifting positions) within the scene.

Static background elements (pink walls, door, floor) show no uniform shifting or fluid motion; no fire, water, smoke, or wind present.


RAW CAPTION: Got it, let's break this down. The task is to generate a caption for the video. First, I need to follow the rules. Let's start by watching the video.

In the first frame, there are a few kids. They're wearing yellow shirts and orange pants, which is a common traditional outfit in some regions. There's a tree in the background, some buildings, grassy area, and a muddy ground. The kids are moving around. Let's check the sequence.

At the beginning (0.0 seconds), a kid in yellow and orange is walking left. Another kid in red is near a tree, maybe holding something. Then, as the video progresses, more kids enter the frame. They're moving in various directions. The main actions: kids are walking around the area, some running. The camera seems to be moving, maybe panning to follow the kids.

Wait, the rules say to focus on motion and behavior in chronological order. So start from the first frame, describe what's happening step by step.

First, the scene: outdoor, grassy area with mud patches, trees, buildings in background. Main subjects: multiple boys (let's count—there are at least 4 or 5). Their appearance: yellow tops, orange bottoms (some maybe red? Wait, in the first frame, one kid is in red, others yellow and orange? Wait, the description says "yellow shirts and orange pants" but maybe some are red. Wait, need to check.

Looking at the frames: first frame has a kid in yellow top and orange pants walking left. Another kid in red (maybe orange? Wait, the problem says "color, size, orientation"). So maybe they're wearing similar colors but different. Let's assume most are yellow shirts and orange sarongs (traditional pants).

Action: The kids are moving around. Initially, one kid is near a pole or tree. Then they start running or walking. The camera moves, following the kids.

Need to describe in chronological order:

- At start, a child in yellow top and orange pants walks left across the muddy ground. Another child in red top and orange pants is near a tree, bending down (maybe handling something). A third child in yellow and orange stands nearby.

- Then, more children enter the scene from the background. They move towards the center, some running. The children are in the open area with grass and trees, buildings in the distance.

- The camera moves slightly, panning to follow the movement of the kids. The ground is muddy with patches of grass. Background has trees and buildings, but minimal description.

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

"Several children in yellow shirts and orange pants move across a muddy grassy area. Initially, a child walks left, while another bends near a tree. More children enter from the background, running toward the center. The camera pans left, following their motion, capturing the dynamic scene."

Wait, check rules: mention spatial relationships. So, "a child in yellow and orange walks left, while another in red and orange bends near a tree (in front of the tree)." But maybe "red" is not accurate; maybe it's orange. Wait, the video shows some kids in red, some in yellow. Let's say "yellow and orange" or "red and orange"?

Looking at the frames: the first kid is in a light-colored shirt, maybe yellow, red pants. Another kid is in red shirt, orange pants. So possible variations.

But the key is chronological. Let's list the steps:

1. The video opens with a child in yellow shirt and red pants walking from right to left across the muddy area. A second child in red shirt and orange pants bends near a tree, holding an object (maybe a stick). A third child in yellow shirt and orange pants stands to the right of the bending child.

2. The bending child continues to work with the object, then a fourth child enters the frame from the background, walking towards the left. The first child runs left, then stops.

3. More children join, running around the area. The camera pans left to follow the movement, keeping the children centered. The background includes trees, a grassy field, and distant buildings, but these are minimal details.

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

"Children in yellow shirts and orange pants move across a muddy grassy field. A child in yellow walks left, while another in red bends near a tree. Additional children enter from the background, running toward the center. The camera pans left, tracking their motion."

But need to be accurate. Let's check the number of children. In the first frame, maybe 3-4 kids. Then more join. Let's say "multiple children".

Also, mention spatial relationships: "a child in yellow shirt and orange pants walks left, while another in red shirt and orange

Multiple children (in orange/yellow) moving by running and walking, interacting with a tree and bucket.

No significant ambient environmental motion (fire, water, wind). Background elements (trees, buildings) are static with no uniform shift.


A person wearing a maroon shirt and dark pants runs toward the camera down a tiled corridor, then turns around, adjusts their head or face, and continues running away. The corridor features planters on the right side with minimal background detail. The camera remains stationary with slight shake.

A single human subject is performing discrete movements: bending to interact with the wall, adjusting clothing, running, and walking away along the corridor.

The background (walls, tiled floor, planters) remains uniformly static with no shifting or fluid motion; no fire, water, smoke, or wind effects observed.


A person with light skin and a light-colored shirt plays a flute, standing in front of a wall with certificates. They gradually turn their torso and shift their stance while continuing to play, their arms adjusting the flute. The dresser with a lamp is to their left, and a bed is to their right. The camera remains static with minimal movement.

A person playing flute: hands and body exhibit deliberate, localized motion from finger movements on the instrument and slight head adjustments.

Static background elements (framed pictures on wall, lamp, table) show no shifting or uniform movement; no fluid motion (fire, water, smoke, wind) present.


A person in a dark blue shirt holds a small blue cylindrical object in their right hand and a clear plastic container in their left. They move the blue object toward the container, inserting it into the container’s open top. The background includes wooden cabinets with glass doors and a yellow wall section. The camera remains stationary, capturing the sequence from a fixed position.

A person is holding a blue bottle and a plastic container, pouring liquid from the bottle into the container; the hand movements and bottle/container interactions are solid, discrete object motions.

Background elements (bookshelves, yellow wall) show no uniform shifting or fluid motion; no fire, water, or smoke present.


RAW CAPTION: Got it, let's tackle this. First, the video shows hands interacting with a white book and some objects. The main subjects are hands (skin tone, not specified but visible), a white book with red text (but rule g says exclude text recognition, so maybe just describe as white book with red lettering), and some tools: maybe pliers or a wire? Wait, in the frames, there's a white object with "ETHICON" but we can't mention text. Let's see the sequence.

Frame 0: Hands holding a small object (maybe a wire with a loop) above a white book. Then frame 1: Hands manipulating the wire, moving it around. Frame 2: Hands using pliers (or some tool) to bend the wire. Frame 3: Hands placing the wire on the book. Frame 4: Hands adjusting the wire, maybe attaching something to the book. Frame 5: Hands holding the wire, now maybe a loop, placing it back on the book.

Wait, the key is to describe motion in chronological order. Main subjects: hands (two hands), white book (position: on surface), wire (color? Maybe metallic, thin). Actions: first, hands hold wire above book, then manipulate wire, use tool to bend, place wire on book, adjust.

Spatial relationships: hands are over the book, moving the wire. Background is plain, minimal. Camera is top-down view, no movement mentioned (stable). Let's structure:

Hands with light skin tone handle a thin metallic wire above a white book with red text. The hands bend the wire using a tool, then position the wire onto the book's surface. The wire is manipulated to form a loop and placed back. The camera maintains a top-down perspective throughout, with no noticeable movement.

Wait, rule b: describe appearance and number. So hands: two hands, light skin (but maybe just "hands"). Object: white book, thin metallic wire. Actions in order: picking up wire, bending with tool, placing on book.

Need to check rules. Exclude text recognition, so can't mention "ETHICON" but the book is white with red text—wait, rule g says "Exclude text recognition", so we can't mention the text. So just describe as a white book. But the video shows "ETHICON" but we have to exclude that. So the book is white, possibly with some text (but don't mention it).

So, hands (two, light skin) manipulate a thin metallic wire above a white book. They bend the wire using a small tool, then place the wire onto the book's surface, adjusting its position. The camera remains in a fixed top-down view, capturing the precise movements without shifting.

Check the rules:

a) Motion: hands handle wire, bend with tool, place on book.

b) Appearance: hands (number 2), wire (thin metallic), book (white).

c) Spatial: hands over book, wire is manipulated on top of book.

d) Camera: top-down, no movement.

e) Background minimal (plain surface).

f) Exclude text, so no mention of "ETHICON".

Let's draft:

Two hands with light skin tone manipulate a thin metallic wire above a white book on a neutral surface. The hands use a small tool to bend the wire, then position it onto the book's surface, adjusting its looped end. The camera maintains a top-down perspective throughout, with no movement.

Wait, in the frames, the book is labeled "ETHICON" but we can't mention that. So just "white book".

Let me check the original video description. The user provided the video frames. The key points:

- Frame 0: hands holding wire over book.

- Frame 1: hands manipulating wire, moving it.

- Frame 2: hands using tool (maybe pliers) to bend wire.

- Frame 3: hands placing wire on book.

- Frame 4: hands adjusting wire on book.

- Frame 5: hands holding wire loop on book.

So chronological order:

1. Hands hold a thin metallic wire above a white book.

2. Hands manipulate the wire, using a small tool to bend it into a loop.

3. Hands place the bent wire onto the book's surface, adjusting its position.

Camera: top-down, static.

So putting it all together:

Two hands with light skin tone handle a thin metallic wire above a white book. They bend the wire into a loop using a small tool, then position it onto the book's surface. The camera remains in a fixed top-down view, capturing the sequential motions without movement.

Background elements, including a red bowl, are visible but minimal.

The person's hands and vegetables (tomatoes, celery, red onion) move as the person places and arranges items on the counter.

The kitchen background (cabinets, countertops) shows no uniform shifting; no fire, water, smoke, or wind is present.


RAW CAPTION: Got it, let's tackle this captioning task. First, I need to focus on the motion and behavior of the main subjects. The main subject here is the man in red shorts. Let's check the frames.

In the first frame, he's sitting with arms raised, maybe lifting something? Wait, the video shows him with arms raised, and then in the next frames, there's some movement. Wait, the frames: [0.0] to [4.7]. Let's see the sequence.

Frame 0: Man sitting, arms up, holding something (maybe a weight?), body with circular marks. Then frame 1-2: same pose? Then frame 3: a red object (like a weight plate?) is thrown or moved from his hands. Frame 4: hands are up, but the weight is gone? Wait, looking at the frames: in [0.0], he has arms raised with hands holding something, then in [2.5], there's a red object flying, maybe he's throwing it. Then [3.6], the red object is moving, and his arms are still up. [4.7] he's still holding his pose.

Wait, the description should be chronological. Let's outline the steps:

1. Man (shirtless, red shorts) sits on equipment, arms raised. Circular marks on chest.
2. He lifts or moves a weight (red object) from his hands, releasing it.
3. The red object flies through the air, while he maintains his pose with arms still raised.

Appearance: shirtless, red shorts, multiple circular marks on chest. Number: 1 man.

Spatial relationships: In front of a large mask (left), behind him is a drum set, and other musical instruments. But the rules say minimal background unless essential. So maybe mention the mask is to the left, but since it's not moving, maybe not essential. Wait, the man is the main subject, so focus on his actions.

Camera perspective: The video is a still image? Wait, no, it's a sequence of frames. The camera doesn't move; it's a fixed shot. So camera is static.

Let's structure it:

- Subject: a shirtless man in red shorts, with circular marks on his torso, sits amidst musical instruments and equipment. He raises his arms. A red object is released from his hands, flying across the frame while he maintains his arm position. The scene remains static with no camera movement.

Wait, check the rules: exclude text recognition (the "DANGER ZONE" sign is text, so don't mention it). Exclude named characters. Focus on motion.

Chronological order:

- Initially, the man sits with arms raised, holding a red weight (or object) above his head. He then releases the object, which flies through the air. Throughout the sequence, he maintains his seated pose with arms up.

Wait, the frames show: [0.0] - he's holding the weight; [1.4] - same; [2.5] - red object is in motion (thrown); [3.6] - object continues moving; [4.7] - object is gone, he's still seated.

So the motion is: the man releases a red object from his hands, which then moves away while he stays seated.

Appearance: shirtless, red shorts, circular marks on chest.

Spatial: The man is seated; to his left is a large mask.

But background is minimal, so maybe just mention the setting as having instruments (drums, keyboard) but not detail them.

Wait, rules say "background descriptions minimal unless essential for understanding motion." So the motion of the object flying might need the background, but the key is the man's action.

So:

The shirtless man in red shorts, with circular marks on his chest, sits on equipment with arms raised. He releases a red object, which flies through the air while he maintains his pose. The camera remains stationary, capturing the action in a fixed shot.

Check if the object is thrown or moved. From the frames, it seems like he throws the object.

Wait, the first frame shows him holding the object, then the next frames show the object moving. So:

At the start, the man holds a red object above his head with both hands. He then throws the object, which moves through the air, while he stays seated with arms raised.

Yes.

Now, check if there are other subjects. Only the man, so number is 1.

Appearance: shirtless, red shorts, multiple circular marks on torso.

Motion: holds object, throws it.

Camera: static.

Putting it all together:

A shirtless man in red shorts, with circular marks on his chest, sits while holding a red object above his head with both hands. He then releases the object, which flies through the air,

A shirtless man is moving his arms and torso rhythmically while seated on a drum kit. His motion is discrete, physically driven by his own actions (locomotion/playing instrument), and easily trackable via bounding box.

No shifting background elements (walls, sign, and drum kit remain stationary). No fluid/environmental motion (fire, water, smoke, or wind) present; all background features are static.

Background elements (tree, house, fence) remain stationary; no fluid or wind motion observed.


A person wearing a light shirt and dark pants operates a blue floor buffer with a black and white base on a wooden deck, moving the machine forward across the planks. The camera gradually zooms in toward the buffer's base as the machine advances, illuminating the wood with its bright light. The brick wall backdrop remains static throughout, with the machine positioned centrally on the deck. The camera perspective shifts from a medium distance to a close-up focus on the buffer's contact with the wooden surface.

The blue floor buffer machine is moving across the wooden deck, and the person operating it is also moving slightly.

The brick wall and wooden deck background are static, with no environmental motion (e.g., no wind, water, or fire).


A person with dark hair wearing a white t-shirt lies in bed under a blue blanket, then raises their right arm and head, sits up slightly while adjusting the blanket, and bends forward with hands near their face. The camera is handheld and slightly shaky, capturing the individual from a close angle as they move.

A person in bed moves: sitting up, rubbing head, adjusting blanket. These are intentional human movements (locomotion, actions).

Background (headboard, wall) is static and not shifting uniformly. No fluid or environmental motion (fire, water, wind) observed.


A man in dark clothing and shorts stands at home plate in an indoor batting cage, swinging a bat to hit a ball.

No shifting background or fluid/environmental motion (fire, water, wind) observed. The blue corrugated wall and dirt road remain static throughout the frames, indicating no dominant ambient motion.


RAW CAPTION: Okay, let's tackle this video captioning task. First, I need to understand the user's requirements. They want a concise, chronological paragraph focusing on the motion and behavior of main subjects. The rules specify to describe appearance, spatial relationships, camera perspective, and exclude text or named characters.

Looking at the video frames provided. The first frame shows a dark scene with a vehicle, maybe a truck or SUV, parked near a building with some text on it. The lighting is dim, so it's nighttime. Then in frame 2, a person in a blue shirt and green pants is seen near the vehicle. They seem to be moving towards the back of the truck.

In frame 3, the person is still near the truck, maybe opening the trunk or interacting with something. Frame 4 shows the person walking away from the truck, moving towards the right side of the frame. The background has some lights, possibly from a building or streetlights, but not much detail.

Frame 5 has the person further away, still moving right, and the vehicle is now on the left side. The camera seems to follow the person's movement. The background remains dark except for the distant lights.

I need to note the main subject: a person in blue shirt and green pants. Their actions: approaching the truck, interacting with it, then walking away. The vehicle is a dark-colored truck. Spatial relationships: the person starts near the truck, then moves to the right. Camera movement: it's following the person, possibly panning right. Background is minimal, nighttime, some distant lights.

Check if I need to mention the building with text, but rule f says exclude text recognition. So skip that. Also, avoid mentioning any names or specifics like "truck" if not necessary, but since it's the main object, maybe just say vehicle. Wait, the first frame shows "BRUSH" on the building, but rule f says exclude text recognition, so don't mention that.

So, chronological order: the person in blue shirt and green pants approaches the dark vehicle, interacts with it (maybe opening the trunk), then walks away to the right. The camera follows their movement, panning right. The background is dark with some distant lights.

Need to keep it concise. Let me structure it step by step:

- Start: Person in blue shirt and green pants approaches a dark vehicle at night.
- Action: They interact with the vehicle (maybe opening the trunk).
- Then: Walk away to the right, moving away from the vehicle.
- Camera: Following the person, panning right.
- Background: Dark, minimal details, distant lights.

Check the rules again. Mention spatial relationships if relevant. So when the person moves away, the vehicle is behind them.

Wait, in frame 2, the person is near the truck, then in frame 3, they walk away. So the vehicle is to the left as they move right.

So the caption should be: A person in a blue shirt and green pants approaches a dark vehicle at night, interacts with it, then walks away to the right while the camera follows, panning right with minimal background details.

Make sure it's concise. Avoid adjectives unless necessary. Maybe "dark-colored vehicle" but maybe "dark vehicle" is enough.

Let me check the example output format. The user provided an example where they mention the person's movement and camera perspective.

Putting it all together:

At night, a person wearing a blue shirt and green pants approaches a dark vehicle, interacts with it, then walks away to the right while the camera follows, panning right with distant lights visible in the background.

Wait, rule c says mention spatial relationships. So when the person moves away, the vehicle is behind them. So "the person walks away from the vehicle to the right".

Yes, "a person in a blue shirt and green pants approaches a dark vehicle, interacts with it, then walks away from the vehicle to the right while the camera follows, panning right."

Check if background is minimal. The user said "keep background descriptions minimal unless essential for understanding motion". Distant lights are part of the background but might be essential for the time of day (night) and context. So "distant lights" is okay.

Check if the person's size is mentioned. The rules say "briefly describe their appearance and number (color, size, orientation)". But the video is blurry, so maybe just mention color of shirt and pants. The size might not be clear, but since it's a person, maybe "a person" without specifying size.

So final caption: At night, a person wearing a blue shirt and green pants approaches a dark vehicle, interacts with it, then walks away from the vehicle to the right while the camera follows, panning right with distant lights visible in the background.

Wait, "the camera follows" might be redundant

A person in blue shirt and green shorts moves across the frame: running toward the car, interacting with it (e.g., opening door), then running away. Discrete solid motion due to locomotion.

Background (building, ground, parked vehicles) is stationary; no fluid/environmental motions (fire, water, smoke, wind) dominate the scene.


A person uses their right hand to hold a white cup containing brown liquid while their left hand holds a black mug. The person tilts the black mug, pouring its contents into the white cup. The camera remains close to the action with a slight shake, capturing the pouring motion from a top-down perspective.

Discrete objects include a person's hands manipulating a pot and cup; the pot is tilted to pour liquid into the cup, with the person's hands and the cup showing controlled motion.

The background (table surface and surrounding elements) appears static with no uniform shifting. No fire, water flow, smoke, or wind-dominated motion is evident beyond the controlled pouring of liquid.


A person wearing a black tank top and zebra-patterned pants holds a large barbell overhead in a squat position, then stands up while keeping the barbell raised, followed by lowering it to the ground. The gym setting features stacked dumbbells and exercise balls in the background. The camera remains static throughout.

The person lifts a barbell from a squat position to overhead, then lowers it and places it on the floor. The barbell and person exhibit distinct physical motion due to weightlifting forces.

The background features static elements including a brick wall, dumbbell rack, and exercise balls. No fluid motion (fire, water, smoke) or wind-induced swaying is observed. Background elements remain fixed without uniform shifting.


Three masked individuals in yellow-black striped shirts and brown pants stand on grass, performing synchronized dance movements with rhythmic arm and leg motions. They maintain a loose formation, each person’s actions coordinated with the others. The background features a bridge and track, but the camera remains static throughout the sequence.

Three people in yellow uniforms are performing synchronized dance moves. Their motion is distinct and solid, involving steps and arm movements.

The background (bridge, building, grass) is stable with no shifting. No fire, water, smoke, or wind-driven motion is visible. Trees in the background are static or minimally swaying but not dominant.


A lively crowd of people in assorted clothing moves energetically beneath large red and yellow banners; some hold poles, one person lifts a green balloon high. The group shifts positions, with individuals advancing and interacting closely, all under the vibrant backdrop. The camera pans slightly left with a subtle shake, capturing the dynamic motion from a low angle.

Multiple individuals (people) are actively dancing and moving within the scene. Their motion is discrete, distinct, and driven by locomotion (dancing), with visible interactions like hand-holding and directional movement across the frame.

The large vertical flags (red, yellow, black) and stage structures form the background; no significant fluid motion (fire, water, smoke) or uniform environmental swaying is observed. Background elements remain relatively stable across frames, indicating no dominant ambient motion.


Three individuals perform near a black iron fence; a guitarist in a dark shirt and blue jeans plays an acoustic guitar, a seated person in a gray sweater sways, and a standing individual in a white jacket and brown pants gestures with their hands. Pedestrians walk past in the background. The camera remains static at eye level.

Discrete solid objects (people) are moving: individuals are playing instruments (e.g., guitar, drums), with visible motion from arm movements and slight body shifts while performing.

The background (metal fence, buildings, ground) shows no uniform shifting or fluid motion (fire, water, smoke, wind). All static environmental elements appear stable across frames.


RAW CAPTION: Got it, let's tackle this. First, I need to describe the video in chronological order. The video starts with a close-up of a monitor showing a traffic scene. Then there's a shift to a newsroom with multiple screens. Let's break it down.

First frame: A monitor displays a traffic camera view with a highway, cars, and a bridge. The monitor is part of a setup, maybe a control room. Then the scene cuts to a wider view of the newsroom, where people are working at desks with multiple screens. There's a person in a suit standing near a bank of monitors, another person in a striped shirt at a desk. Then the camera moves to another angle, showing a person in a dark jacket working at a desk, with screens showing traffic data.

Wait, need to focus on motion and behavior. The initial shot is a static monitor, then camera pans or cuts to the newsroom. So sequence:

1. Close-up of monitor showing highway traffic (cars moving on the road, bridge in background).
2. Camera cuts to a wider newsroom scene: people working at desks, multiple monitors displaying traffic footage. A person in a dark cap and jacket stands near screens; another person in a striped shirt is seated, working.
3. Camera shifts to show another section of the newsroom, focusing on a person in a dark jacket working at a desk with multiple screens showing traffic data.

Also, mention spatial relationships: the monitor is part of a setup, people are seated at desks with monitors in front of them, standing near other screens.

Camera movement: Starts with a close-up, then cuts to wider shots, possibly panning across the newsroom.

Need to avoid text recognition. So the text on the screen (like "16 WRONG-WAY DEATHS SINCE 2014") is not to be mentioned.

Focus on people's actions: working at desks, standing near monitors, looking at screens.

Let's structure it:

The video begins with a close-up of a monitor displaying a traffic camera view showing cars moving on a highway with a bridge in the background. The camera then cuts to a wider view of a newsroom where several people are seated at desks working on computers, with multiple screens showing traffic footage; a person in a dark cap and jacket stands near a bank of monitors, while another individual in a striped shirt is focused on their desk. The camera shifts to show another section of the newsroom, highlighting a person in a dark jacket working at a desk with multiple screens displaying traffic data. The camera perspective transitions from a close-up of the monitor to wide shots of the newsroom, panning across the workspace to capture the activity.

Wait, check rules: "conclude with camera perspective and movement". So end with that.

Also, keep background minimal. The newsroom has desks, computers, screens.

Let me rephrase to be concise, chronological:

The video opens with a close-up of a monitor showing a highway traffic camera view with moving cars and a bridge. It then cuts to a wider shot of a newsroom where multiple individuals are working at desks with computers; one person in a dark cap stands near a bank of monitors displaying traffic footage, while another in a striped shirt is seated at a desk. The camera pans across the newsroom to show a person in a dark jacket working at a desk with several screens showing traffic data, ending with a wide view of the workspace. The camera transitions from close-up to pan across the newsroom, capturing the motion of people working and screens displaying traffic.

Wait, check rule d: "Conclude with the camera perspective and movement (e.g., top-down, pan left, slight shake)." So need to say the camera movement at the end.

First scene: close-up of monitor (no movement initially), then cuts to wider newsroom, then pans across.

Let me structure:

The video begins with a close-up of a monitor displaying a traffic camera view of a highway with moving cars and a bridge. The camera cuts to a wider shot of a newsroom where several people are seated at desks with computers, one person in a dark cap stands near a bank of monitors, and another individual in a striped shirt works at a desk. The camera then pans across the newsroom to focus on a person in a dark jacket working at a desk with multiple screens showing traffic data, concluding with a pan across the workspace.

Yes, that's better. Make sure to mention motion: the camera cuts (from close-up to wider), then pans.

Check if main subjects: the monitor, the people in the newsroom. Their behavior: working, standing, looking at screens.

Appearance: the person in dark cap, striped shirt, dark jacket.

Spatial: the person in dark cap stands near monitors (so "near" or "to the left" etc., but in the description, say "a person in a dark cap stands near a

Discrete solid objects: people seated in control room, occasionally shifting positions; screens displaying traffic data and graphs.

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


A drummer wearing a hat and dark shirt, an accordion player with a red and white instrument, and a small child stand near a wall under a blue awning, performing. Pedestrians in blue tops and plaid shirts walk past them from right to left. The camera pans left slightly, capturing the crowd’s movement while maintaining focus on the musicians.

Discrete solid objects (people) are moving: individuals walk, run, and interact in the scene. Examples include the woman in blue, the man in plaid shirt, and the person in striped shirt passing through the frame.

The background (wall with posters, blue tent, and concrete ground) shows no uniform shifting or fluid motion. No fire, water, smoke, or wind is visible in the scene.


A group of soldiers in green camouflage uniforms stand outdoors, some saluting, before the scene transitions to an indoor space where more soldiers in matching uniforms form a line and salute. The soldiers are tall, wearing caps and uniformed attire, maintaining a rigid stance as they raise their right hands to their foreheads. The outdoor setting features trees and buildings, while the indoor location has green and white walls. The camera remains static throughout, capturing medium shots of the soldiers in both environments.

Discrete solid objects (military personnel) are performing salutes, involving coordinated upper-body motion (arms raising to foreheads). Soldiers are tracked across frames with consistent bounding boxes.

No shifting background elements or fluid/environmental motion (e.g., fire, water, wind) observed. Background includes static buildings, trees, and indoor walls/floor with no uniform motion.


A person with long dark hair and a black top applies mascara using a wand, moving it upward and downward along the eyelashes. The camera maintains a static close-up perspective throughout the sequence.

Static wall background with no shifting or environmental fluid motion (fire, water, wind).


A boy holds a blue accordion, rotating it to display its front and sides. The instrument features visible keys and a rectangular shape, with the boy’s hands adjusting its position as he moves it slightly in front of him. The background includes a room with a window showing string lights and a door, but details are minimal. The camera remains stationary, capturing the scene from a frontal perspective.

The boy's hands are moving the accordion (a solid object) in a rhythmic manner to play the instrument, showing discrete physical interaction.

The background (walls, door, windows, and furniture) is stationary with no fluid/environmental motion. No fire, water, smoke, or wind dominates the scene.


RAW CAPTION: Got it, let's break down the video. First, the main subject is a man in a yellow shirt and blue shorts. He's working on a brick wall under a tiled roof. The video starts with him using a trowel to apply or smooth something on the wall. Then he moves around, maybe adjusting his position. The camera seems to be stationary, but wait, the timestamps go from 11:44:42 to 11:44:48, so maybe it's a fixed camera angle. Let's check the rules: focus on motion and behavior chronologically.

He's standing on a platform or scaffold, working on the wall. The wall has bricks and some areas are being worked on. The roof is tiled, so that's the background. The man moves his trowel across the wall, so his actions are applying material. Spatially, he's in front of the wall. Camera perspective: seems like a static shot, maybe slightly tilted, but the output should mention camera perspective. Rules say "conclude with camera perspective and movement".

Wait, the video starts with him at a certain position, then he moves a bit, maybe stepping or shifting. Let's list the sequence:

- Man in yellow shirt, blue shorts, standing on a platform under a tiled roof.
- He uses a trowel to work on a brick wall (applying or smoothing material).
- Moves slightly across the wall, continuing his task.
- Camera is fixed, top-down? Wait, the angle is from above, but maybe not top-down. Wait, the frames show the roof above, so the camera might be mounted on the roof or high up. But the rules say minimal background, so maybe just say "fixed camera angle".

Wait, the output needs to be chronological. So first, the man is working, then he moves. Let's put it all together.

Man in yellow shirt and blue shorts stands on a platform beneath a tiled roof, using a trowel to apply material to a brick wall. He shifts position slightly, continuing to smooth the surface as he moves from left to right along the wall. The camera remains stationary, capturing the action from a fixed overhead angle.

Wait, check the rules: "conclude with camera perspective and movement". So "fixed overhead angle" might be right. Also, mention appearance: yellow shirt, blue shorts. Number: one man. Spatial: in front of the wall.

Let me check the video frames. The first frame shows him at the left, then moving right. So chronological: he starts on the left, trowel on the wall, moves to the right, continues working.

So the caption should be:

A man wearing a yellow shirt and blue shorts stands on a platform beneath a tiled roof, using a trowel to apply material to a brick wall. He moves gradually from left to right along the wall, smoothing the surface with his tool. The camera remains fixed in position, capturing the action from a steady overhead angle.

Wait, "overhead" might not be exact. The roof is above, so maybe "fixed angle from above". But the rule says "camera perspective and movement". Let's say "fixed camera angle, slightly tilted".

Wait, the rules say "keep background descriptions minimal unless essential". So the roof is tiled, but maybe not necessary. Wait, the wall is brick, so that's part of the action.

Wait, in the video, the wall is partially built, with some bricks and some dark material (maybe cement) being applied. The man is working on that.

Let me rephrase:

A man in a yellow shirt and blue shorts stands on a platform under a tiled roof, using a trowel to smooth dark material on a brick wall. He shifts his position slightly, moving from left to right as he continues applying the material. The camera remains stationary, capturing the scene from a fixed angle.

Yes, that's concise. Let's check the rules:

a) motion and behavior chronologically: describes him moving from left to right, smoothing material.

b) appearance: yellow shirt, blue shorts, one man.

c) spatial: under roof, platform, in front of wall.

d) camera: fixed angle.

e) background minimal: roof and wall are necessary for context but not too much.

f) exclude text, named characters: good.

g) no reasoning.

So final caption:

A man wearing a yellow shirt and blue shorts stands on a platform beneath a tiled roof, using a trowel to apply dark material to a brick wall. He moves slightly from left to right along the wall, continuing to smooth the surface. The camera remains fixed, capturing the action from a steady angle.
