RAW CAPTION: Got it, let's break this down. First, the video shows a person in a gym. The main subject is a person lying on a bench or mat, doing an exercise with a purple medicine ball. Let's check the sequence: at 0.0 seconds, the person is lying down, holding the ball near their chest. Then they lift the ball up, maybe doing a chest press. The next part is text on screen, but we have to exclude text recognition per the rules. So focus on the motion.

Appearance: the person is wearing black clothes, red shoes. The medicine ball is purple. They're on a gym floor with equipment in the background (bicycles, weights), but minimal background description.

Chronic order: starts lying down, raises the ball, holds it up, then maybe lowers it. Then the screen goes to black with text, but since we exclude text, we stop at the action. Wait, the video has a frame where the person is lifting the ball, then the text. But the task is to describe the video up to the text? Wait, the user provided the frames: the first part is the exercise, then at 5 seconds, the text appears. So the caption should include the action up to the text, but since text is excluded, maybe the action ends with the person doing the exercise, then the text is shown but we don't mention it.

Wait, rule f: exclude text recognition. So the text "Exercise set 3..." is not to be mentioned. So the caption should describe the person's actions before that.

So the main subject: a person in black clothes, red shoes, lying on a gym floor. They hold a purple medicine ball. They start by holding it near their chest, then lift it upward in a chest press motion, raising it to shoulder height. Then, the screen cuts to black with text (but we don't include that). So the chronological order: the person performs a medicine ball chest press, lying on the floor, moving the ball from chest to raised position.

Now, spatial relationships: the gym has bicycles in the background, but minimal. So "in a gym setting with exercise equipment visible in the background" but minimal. Rule e says minimal background description.

Camera perspective: the video is shot from a fixed angle, probably static, no movement mentioned. So "static camera" or "fixed angle".

Putting it together:

A person wearing black athletic wear and red shoes lies on a gym floor, holding a purple medicine ball at chest height; they lift the ball upward in a chest press motion, raising it to shoulder level. The background features gym equipment including stationary bicycles, but the focus remains on the individual's exercise motion. The camera maintains a static position throughout the sequence.

Wait, check rules: c) mention spatial relationships if relevant. The person is on the floor, equipment is in the background, so that's spatial. d) conclude with camera perspective: static.

Let me structure:

- Main subject: person (appearance), action (chronological motion).

Start: lying on floor, holding purple medicine ball at chest. Then lifts it up. Then maybe the next frame shows the ball at the top. But the video is short: from 0 to 5 seconds. The first frame (0.0) is lying, then 1.4 shows them raising, etc.

So step by step:

At 0.0s, the person is lying on a gym floor, wearing black clothes and red shoes, holding a purple medicine ball close to their chest. At 1.4s, they lift the ball upward in a chest press motion. By 3.0s, the ball is raised to shoulder height. Then the screen transitions to a black screen with text (but we don't mention text).

So the caption should be: A person in black athletic attire and red shoes lies on a gym floor, performing a chest press exercise with a purple medicine ball, lifting it from chest height to shoulder level. The background includes stationary bicycles and weight equipment, but the focus is on the individual's motion. The camera remains stationary throughout the sequence.

Check rules: a) chronological order: yes, starts lying, lifts ball, raises to shoulder. b) appearance: black clothes, red shoes, purple ball. c) spatial: gym floor, equipment in background. d) camera: stationary. e) minimal background: includes bicycles, weight equipment, but minimal. f) exclude text: correct, didn't mention text. g) no reasoning.

Let me make it concise:

A person in black athletic wear and red shoes lies on a gym floor, lifting a purple medicine ball from chest height to shoulder level in a chest press motion. The background includes stationary bicycles and weight equipment, but the focus remains on the individual’s exercise. The camera maintains a static position.

<caption_output>A person in black

A person lying on the floor performs a theraband chest press, moving their upper body and legs in discrete, intentional motions due to physical exertion.

The gym background (walls, floor, stationary equipment) is static with no shifting or fluid motion; no fire, water, smoke, or wind present.


A man in a black shirt and white shorts stands on a grassy field, facing forward with a golf club. He raises the club behind his head, swings it forward to strike a golf ball, and follows through with his body motion. The camera remains stationary, capturing his full swing from a frontal perspective.

A person (discrete solid object) performs a golf swing, with arm/body motion and a golf ball traveling after impact. Both the person and ball exhibit motion due to physical forces (swing mechanics and collision).

Background elements (grass, trees, structures) remain stationary across frames, showing no uniform shifting. No fire, water, smoke, or wind-driven fluid motion is present.


A man in a white shirt and brown shorts stands on a reflective surface, mirrored symmetrically, performing sequential arm movements: beginning with arms raised upward, then extending them outward horizontally, followed by bringing arms together above his head, and finally raising them into a V shape. The background includes a field of red flowers and a blue sky. The camera remains static throughout.

Two distinct human figures (appearing mirrored due to reflection) perform synchronized arm and body movements. Motion is deliberate and consistent with intentional locomotion.

Background elements (sky, trees, dock) show no shifting or movement. The water is calm with clear reflections, indicating no fluid environmental motion (fire, water flow, smoke, wind).


A man in a white shirt adjusts the long dark hair of a seated woman in a dark top, moving his hand from her shoulder over her head. The woman faces away from the camera, seated in front of a piano against a brown wall backdrop. The camera remains static with slight shaking.

Man in white shirt actively moves hands/arms to adjust the seated person's hair; discrete human motion due to deliberate physical action.

Background elements (piano, wall) are static; no fluid motion (fire, water, smoke, wind) detected. Environment appears still.


A person in dark clothing rides a brown mechanical bull in a dimly lit space. The bull bucks vigorously, causing the rider to lose balance and fall off. The camera remains steady, capturing the motion from a fixed position.

The bull (discrete animal object) is bucking vigorously, causing the rider (discrete human object) to move dynamically in response. Both objects exhibit clear physical interactions due to locomotion and force application.

The background (arena walls, overhead lights) is static with no uniform shifting. No fluid or environmental motion (fire, water, wind) is dominant; the scene is primarily composed of solid objects.


A person in a white dress shirt and blue-yellow bow tie adjusts the bow tie, then spreads arms outward to adjust the shirt collar, followed by raising hands to adjust glasses near the ears. The green background remains consistent. The camera maintains a static close-up perspective throughout.

A person (wearing a white shirt and bow tie) is moving hands to adjust the bow tie and performing gestures. Discrete solid objects (person's body, hands, bow tie) exhibit intentional locomotion.

The background is a uniform solid green with no shifting elements or fluid motion (fire, water, smoke, wind). Background is static and does not exhibit environmental fluid dynamics.


RAW CAPTION: Got it, let's break this down. The video starts with a close-up of a hand holding a corkscrew, then the hand moves to show the corkscrew with a cork. Then it cuts to a man in a black shirt pouring wine from a bottle into a glass.

First, identify the main subjects and their actions. The sequence: hand with corkscrew (close-up), then hand showing cork, then man pouring wine.

For the caption, need chronological order. Start with the hand holding corkscrew. Then the hand displays the cork with the wire. Then the man (in black polo) pours wine into a glass. Background is blurred greenery, but minimal. Camera starts close-up, then shifts to wider shot of the man.

Check rules: focus on motion and behavior. Main subjects: hand, corkscrew, cork, man, bottle, glass.

First part: hand (close-up) holds a corkscrew. Then hand moves to show corkscrew with cork (so the cork is now attached, maybe with wire). Then the scene changes to a man (black shirt) pouring wine from a bottle into a glass. The background is outdoor with greenery, but minimal description.

Mention appearance: corkscrew is metallic, cork is brown (since cork is typically brown), man's shirt is black. Bottle is green. Glass is clear with wine.

Spatial: first close-up of hand, then the hand (now showing the cork) is in front of a green bottle? Wait, the second frame shows a hand holding the corkscrew with a cork, and a green bottle in the background. Then third frame, the man is at a table with a green cloth, pouring from green bottle into glass.

Chronological order:

1. A close-up shot shows a hand gripping a metallic corkscrew.

2. The hand then adjusts to display the corkscrew with a brown cork secured by wire, with a green bottle visible in the background.

3. The scene transitions to a man in a black polo shirt pouring wine from a green bottle into a clear glass placed on a wooden table with a green cloth, set against blurred outdoor foliage.

Check rules: exclude text (the shirt has "ine" but that's text recognition, so don't mention). No named characters. Keep background minimal: "blurred outdoor foliage" is essential for context but not too much.

Camera movement: starts with close-up (top-down? No, close-up), then shifts to wider shot (pan left? Or transition to wider angle). The first part is close-up, then the third frame is a wider shot of the man. So camera perspective changes from close-up to medium shot.

Putting it all together:

A hand holds a metallic corkscrew in a close-up view. The hand then shows the corkscrew with a brown cork secured by wire, with a green bottle nearby. The scene shifts to a man in a black polo shirt pouring wine from a green bottle into a clear glass on a wooden table, set against blurred greenery. The camera starts with a close-up of the hand and transitions to a medium shot of the man.

Wait, need to be concise. Let's check the output format. Must be a paragraph. Let's structure:

A hand grips a metallic corkscrew in close-up, then displays the corkscrew with a brown cork secured by wire, with a green bottle visible in the background. The scene transitions to a man in a black polo shirt pouring wine from a green bottle into a clear glass on a wooden table with a green cloth, set against blurred outdoor foliage. The camera begins with a close-up shot and shifts to a medium view of the man.

Check if it's chronological. Yes: first close-up hand, then hand with cork, then man pouring. Appearance: corkscrew metallic, cork brown, bottle green, shirt black. Spatial: hand in close-up, bottle in background for the cork shot; man at table with glass. Background minimal: blurred foliage.

Make sure to follow rules. No text recognition (so ignore "ine" on shirt). No named characters. Keep it concise.

Another version: Close-up of a hand holding a metallic corkscrew. The hand then presents the corkscrew with a brown cork secured by wire, with a green bottle nearby. Next, a man in a black polo shirt pours wine from a green bottle into a clear glass on a wooden table with a green cloth, against blurred greenery. The camera starts with a close-up and transitions to a medium shot.

Yes, that's good. Check for conciseness. "Grips" to "holds". "Presents" might be better. "Displays" as in the second frame.

Final check: chronological order, motion and behavior, appearance (color, size, orientation), spatial relationships (nearby, on table), background

A hand removing a cork from a wine bottle (discrete object motion), and a man gesturing with a wine bottle (discrete object motion).

No shifting background elements; no fire, water, smoke, or wind as dominant motion.


A woman in a dark pinstripe suit and white shirt speaks while positioned centrally against a blurred, multicolored background. The frame briefly darkens, then she reappears in the same position. Subsequently, a diamond-shaped dark object covers her face. The camera remains static with slight frame shifts during transitions.

The news anchor (a person) is moving due to speaking and gesturing. The motion is discrete and solid.

The background (blue and yellow graphic) is static and does not shift. No fluid or environmental motion (fire, water, wind) is present.


A single dark silhouette of a person is visible against a soft pink background, facing away from the camera. The person’s head and upper body shift slightly, moving the head downward and forward, then the silhouette gradually fades into darkness as the frame darkens.

A dark, solid object (likely human hair or a head) moves across the frame from the top left toward the bottom right, exhibiting distinct motion patterns consistent with locomotion or head movement.

The background shows a gradient sky with a bright light source; no uniform shifting of static background elements (e.g., walls, ground) is observed, and there is no fluid or gaseous environmental motion (fire, water, smoke) dominating the scene.


A person with long light hair and blue sleeves uses a tool to carefully apply color to a small bluebird-shaped object on a white surface, their hands moving methodically as the bluebird gradually takes on green and blue hues. Other green objects rest on the surface nearby. The camera maintains a top-down close-up perspective, centered on the hands and the object being colored, with minimal background detail.

The person's hands and the objects they are manipulating (green and red items) are moving due to explicit physical forces (hand movements).

No shifting background elements; no fluid or environmental motion (fire, water, smoke, wind) observed.


A pair of hands enters the frame, holding a small bowl of fresh green cilantro leaves, and sprinkles the herbs over a golden-brown pizza with melted cheese and toppings resting on a granite countertop. The hands move methodically, distributing the cilantro across the pizza’s surface. The camera remains static, closely focused on the pizza and the sprinkling action, with minimal background elements visible.

A hand is moving to sprinkle cilantro (discrete solid object) onto the pizza, with controlled motion originating from explicit physical action (hand movement).

The granite countertop, bottle, and cloth in the background are stationary with no shifting or environmental motion (fire, water, smoke, or wind).


A group of people in dark winter clothing stand on a snow-covered playground, gathered near red playground equipment. They shift positions slightly, moving closer to the structure as the camera pans and shakes subtly, capturing the snowy ground and surrounding playground features.

Groups of people are moving across the scene, walking and interacting on the snowy ground. These are solid objects exhibiting locomotion (walking) as the primary motion.

The snowy ground and playground structures (fence, slide, bench) are static; no fluid motion (fire, water, smoke) is visible. Snow is solid and not flowing, so ambient environmental motion is absent.


Three children cluster around a television; a boy in a dark blue hoodie with white stripes, a girl with pink hair ties in a pink shirt, and a girl in a white shirt and blue overalls lean forward, all focused on the screen. The middle child slightly shifts her head, the right child adjusts her stance, while remaining engaged. The camera remains stationary with minor shake, positioned at eye level.

Three children are interacting; they lean in and shift positions, showing motion due to physical forces (e.g., pushing, turning, and social interaction).

Background elements (TV, wall) are stable with no uniform shifting or environmental fluid motion (fire, water, smoke, wind).


A pair of hands manipulates a purple crocheted piece and a pink crochet hook; the left hand (with light-colored nail polish) adjusts the yarn while the right hand inserts the hook into stitches, moving the hook through the yarn to form new stitches. The hands shift the crocheted piece slightly as the hook interacts with the yarn, with the camera maintaining a close-up, slightly shaky perspective focused on the detailed crocheting motion. Background elements remain indistinct and minimal.

Hands manipulating a purple crochet hook and blue yarn exhibit controlled, deliberate motion consistent with crocheting (looping yarn, pulling, positioning).

Background elements (white fluffy surface, dark areas) show no uniform shifting or fluid motion; no fire, water, or smoke present.


A group of children and adults gather outside a building entrance. A person in a white shirt holds a chalkboard high above the crowd, then steps back, prompting children in green, striped, and black shirts to shift positions and look upward. Adults nearby adjust their stances, including a woman in black turning toward the group. The camera maintains a frontal perspective with slight movement as the scene unfolds.

Discrete solid objects (people) are moving: individuals are gesturing, turning, and shifting positions within the crowd.

The background features a static wall, chalkboard, and potted plants that show no uniform shifting or environmental fluid motion (fire, water, smoke, wind).


The video depicts a digital checkers game on a mobile screen. Initially, red and white pieces are positioned on a green and white checkered board. A red piece moves diagonally toward a white piece, capturing it. Subsequently, a white piece moves diagonally to capture a red piece, resulting in the red piece being removed from the board. The sequence concludes with the game ending as indicated by the screen transition. The camera maintains a top-down static view throughout, focusing solely on the game board and piece movements.

Discrete red and white circular objects (likely game pieces) move across the checkered board in discrete, directional paths.

The checkered board background remains static across frames; no fluid/environmental motion (fire, water, wind) is present.


tags. The example in the problem statement shows that. So, must follow the format exactly.  Also, need to mention the number of subjects: one person. His appearance: black t-shirt, but no text. The bar has glasses and bottles, but background minimal. So maybe: A man in a black t-shirt sits behind a light-colored bar with two empty glasses. He gestures with both hands to his right, then returns hands to the bar surface. Two mounted screens display changing content above the bar. The camera remains static in a medium shot.  Wait, the original frames: in [0.0] he's sitting, hands on bar. Then [1.4] he gestures right, [2.5] continues, [3.6] brings hands back. So chronological sequence: starts seated, gestures right, then hands back to bar.  Including spatial relationships: the man is behind the bar, screens above. The empty glasses are in front of him on the bar.  The caption must not include text, so no "Get Your Liquor" etc.  Final check: concise, chronological, focus on motion. No text, minimal background.  So: A man in a black t-shirt sits behind a light-colored bar with two empty glasses. He gestures outward with both hands to his right, then returns his hands to the bar surface. The setting features two mounted screens above the bar displaying changing content. The camera maintains a static medium shot throughout. </think>  <caption_output>A man in a black t-shirt sits behind a light-colored bar with two empty glasses. He gestures outward with both hands to his right, then returns his hands to the bar surface. Two mounted screens above the bar display changing content. The camera maintains a static medium shot throughout.

The person (a solid, distinct object) is moving his hands and arms, which is due to his own locomotion (gesturing while speaking).

The background (wall, bar, and screens) is static and does not shift uniformly. No fluid or environmental motions (fire, water, smoke, wind) are present.


RAW CAPTION: Got it, let's tackle this. First, the video starts with a top-down view of a glass bowl with strawberries and other fruits on a wooden surface, and a cutting board with garlic. Then, a hand with a blue plaid sleeve moves the bowl to a blue food processor. The next step is the ingredients being blended in the processor. Then, a hand adds a white substance (yogurt, as per the text but we don't mention text) and then honey.

Wait, the rules say exclude text recognition, so we can't mention "1/2 tasse de yaourt" or "1 cuillère à café de miel". So focus on actions. Let's break it down chronologically.

First scene: glass bowl with sliced strawberries and maybe bananas or other fruit, on wooden surface. Then, a hand (blue plaid sleeve) places the bowl into a blue food processor. Then, the processor is turned on, blending the fruit into a red mixture. Then, a hand adds a white substance (yogurt) from a small bowl into the processor. Then, a hand adds honey using a spoon.

Wait, the video sequence:

0.0s: glass bowl with fruit (strawberries, maybe apples, bananas) on wooden table, cutting board with garlic.

1.4s: hand with blue plaid sleeve holds food processor with fruit inside.

2.5s: food processor blending, fruit mixed into red pulp.

3.6s: hand adds white substance (yogurt) from small glass container into the processor.

4.7s: hand uses spoon to add honey (golden liquid) into the processor.

Now, chronological paragraph. Focus on motions and main subjects (hands, food processor, fruit, etc.)

Start with the first scene: a glass bowl filled with sliced strawberries and other fruits sits on a wooden surface next to a cutting board with chopped garlic. Then, a hand with a blue plaid sleeve places the bowl into a blue food processor. The processor is activated, blending the fruit into a red mixture. A hand then adds a white substance from a small glass container into the processor, followed by a hand using a spoon to add honey.

Check rules: no text, so don't mention the text on screen. Mention spatial relations? The bowl is on the wooden surface next to the cutting board. Then the hand moves the bowl into the processor. Then the blending. Then adding ingredients.

Camera perspective: top-down throughout, as per the video. So the camera is top-down, no movement mentioned.

Background: wooden surface, cutting board, but minimal as per rules.

Let's structure:

Initially, a glass bowl with sliced strawberries and other fruits rests on a wooden surface beside a cutting board with garlic pieces. A hand with a blue plaid sleeve places the bowl into a blue food processor. The processor blends the fruit into a red mixture. Subsequently, a hand adds a white substance from a small glass container into the processor, then a hand uses a spoon to add a golden liquid (honey) into the processor. The camera maintains a top-down view throughout.

Wait, check for "golden liquid"—but maybe just "honey" but the rule says exclude text recognition, but the action is adding a liquid, so "a golden liquid" might be okay, but maybe better to say "a viscous liquid" but in the video it's honey. But the rules say exclude text recognition, so we can describe what's visible. The text on screen is in French but we ignore it. So the honey is a liquid being added with a spoon. Maybe "a viscous liquid" but the video shows honey, but since we can't mention text, just describe the action.

Alternatively: a hand pours a white substance (yogurt) into the processor, then adds honey using a spoon.

Wait, the instructions say "briefly describe their appearance and number". So the white substance is a white creamy material (yogurt), honey is golden and viscous.

But let's check the rules: exclude text recognition, so we can't say "yogurt" or "honey" because that's text? Wait, no—text recognition is like the on-screen text (like "1/2 tasse de yaourt"), but the actual content of the video (the yogurt itself) is a substance. So we can describe the substance as "white creamy substance" and "golden viscous liquid".

Wait, the task says: Exclude text recognition, named characters, or stylistic analysis. So if the video shows yogurt, we can refer to it as yogurt, but the text on screen is what to exclude. So "yogurt" and "honey" are okay because they are part of the visual, not text. But the text recognition refers to the on-screen text. So the video shows the ingredients,

Discrete solid objects include the blender (rotating blades and contents), the hand pouring a white substance, and the fruit inside the blender. Motion is driven by explicit physical forces (blender operation and manual pouring).

The background consists of a static wooden surface with no shifting elements or fluid/environmental motion (e.g., no fire, water, or wind effects observed).


A child in a yellow shirt crouches near a sand pile, using a tool to move sand, while an adult in a blue cap, sleeveless shirt, and white shorts stands to the right observing. The scene occurs at a construction site with stacked bricks in the background, captured via a static camera perspective.

A single person (worker) is moving within the construction site, likely performing physical labor (e.g., handling materials). No other discrete objects exhibit significant motion.

No shifting background elements (brick walls, ground are static). No fire, water, smoke, or wind effects observed in the scene.


RAW CAPTION: Got it, let's tackle this video captioning task. First, I need to understand the video content. The video shows a wedding scene with a bride and groom. The bride is in a white dress with a veil, the groom is in a black suit with a white flower. They're standing at a table with a white cloth. The bride is lighting a candle from the groom's candle.

Now, following the rules. Start with chronological order. First, the bride is holding a candle, then she lights the groom's candle. Wait, looking at the frames: in the first frame, bride is holding a candle, maybe lighting a smaller candle on the table. Then she moves towards the groom's candle. So the action is the bride lighting the candle from the groom's candle? Wait, no, the groom is holding a candle, and the bride is lighting something. Wait, the video shows the bride using a candle to light the candle on the table, then maybe the groom's candle? Wait, the description says "the bride uses a candle to light a candle." Wait, the frames: she's holding a candle (maybe a taper) and lighting the one on the table. Then the next frame, she moves closer to the groom, who is holding a candle. Wait, let's check the frames.

First frame: bride in white dress, veil, holding a small candle (maybe a taper), groom in black suit with white flower, holding a candle. The table has a white cloth, a lit candle. Bride is lighting a candle on the table? Wait, the third frame: she's using the candle to light the groom's candle? Wait, the groom is holding a candle, and the bride is lighting his candle. Wait, no, the bride is lighting a candle on the table. Wait, maybe it's the unity candle ceremony. So the bride and groom each have a candle, then they light the unity candle.

Wait, the video description: in the first few frames, the bride is holding a candle, then she lights the candle on the table. Then she moves to the groom's side, maybe lighting his candle? Wait, the frames: [0.0] bride holding a candle, groom holding a candle. Then [1.4] bride is moving, maybe lighting the candle on the table. Then she continues to light the candle. Wait, the main action is the bride lighting a candle. Let's describe the motion.

Chronological order: The bride, wearing a white wedding dress with a veil, holds a candle. She approaches a table with a white cloth where a candle is placed. She uses the candle to light the candle on the table. Then she moves slightly closer to the groom, who is standing to her right, holding a candle. The groom remains stationary, observing the action. The background has a wall with a red sconce and flowers on a stand, but minimal details. Camera perspective: slight movement, maybe a small pan or shift, but overall steady. The camera is at eye level, capturing the two subjects in the foreground.

Now, following the rules:

- Focus on motion and behavior: bride lights candle, moves towards groom, groom holds candle.
- Appearance: bride in white dress, veil; groom in black suit, white flower, holding candle.
- Spatial relationships: bride to left of groom, both in front of table.
- Background: minimal, just wall and some decor.
- Camera: slight movement, maybe pan left, but the frames show the camera moving a bit but not much. The user's frames have the camera shifting, maybe a pan left.
- Exclude text, names, etc.

Let's structure the paragraph:

The bride, dressed in a white gown and veil, holds a candle and lights a candle on a white-clothed table, then moves slightly toward the groom, who stands to her right in a black suit with a white flower and holds a lit candle. The groom remains stationary, observing the action. The camera shifts slightly, maintaining a steady focus on the couple as the bride performs the lighting motion. Background elements are minimal, featuring a wall with a red sconce and floral arrangements.

Wait, need to check the chronological order. First, the bride is lighting the candle (the table one), then she moves toward the groom. So the sequence: bride uses candle to light the table candle, then moves closer to groom. The groom is holding a candle, maybe his own.

So the caption should be:

A bride in a white gown with a veil uses a candle to light a candle on a white-clothed table, then moves slightly toward the groom standing to her right, who wears a black suit with a white flower and holds a lit candle. The groom remains still, observing the action. The camera shifts minimally, capturing the couple from a slightly elevated perspective as the bride completes the lighting motion.

Wait,

Bride's hands move as she gestures while speaking, and groom remains mostly stationary with minimal head/shoulder motion. Both are discrete solid objects exhibiting intentional movement.

Background elements (walls, door, fire extinguisher, decorations) remain static with no uniform shifting or fluid motion (fire/water/smoke/wind).


Four girls stand together; the central girl in a colorful floral dress holds a thin object and gestures with both hands while speaking, the girl to her left wears a light blue sleeveless top and the girl to her right wears a pink dress, both with hands slightly raised. A hand enters the frame from the bottom right holding a calculator displaying numbers, positioned in front of the central girl. The camera remains steady in a medium shot, capturing the group from the front.

Multiple human subjects (children) are making hand gestures and interacting; their movements are distinct, solid-object motions driven by physical actions.

Background elements (walls, interior structures) are stationary; no fluid motion (fire, water, smoke) or wind-driven movement is observed.


A person wearing a dark shirt uses a knife to slice a white onion on a wooden cutting board in a kitchen. They position the onion, make a downward cut, and rotate the onion to continue slicing. The background includes a sink, pots, and shelves with various kitchen items. The camera remains static, focusing on the cutting board and the person’s hands.

The person's hands and the onion are moving due to deliberate cutting actions; the knife slices the onion, creating discrete motion of solid objects.

The kitchen background (shelves, sink, and stationary items) is static with no shifting or environmental motion (fire, water, smoke, wind).


RAW CAPTION: Got it, let's tackle this. First, I need to observe the video. The main subjects are kids playing a game in an indoor gym. Let's break down the sequence.

In the first frame, there are kids in two groups: one with dark jerseys (maybe black or dark blue) and another with white. The dark group is in the center, white group is on the opposite side. Wait, the first frame shows them standing. Then, in the next frames, they start moving. The dark jerseys run towards the white group, maybe? Let's see the actions.

From the video description: they start with kids in dark shirts and white shirts. The dark group is moving towards the center, maybe? Wait, the sequence shows the dark team moving, then the white team moving too. Wait, the motion: in frame 0, they're positioned. Then frame 1-5, they start running. The dark group (maybe 8 kids?) and white group (maybe 10?), but need to count. Wait, the problem says concise, so maybe don't get too specific on numbers but mention "groups" or "teams".

Chronological: Initially, players in dark and white jerseys are positioned on the court. Then, the dark jersey team starts moving towards the center, followed by the white team. They converge, maybe a play is happening. Then, in frame 4-5, they're running towards each other? Wait, the video shows the dark team moving left or right? Wait, the video's frames: frame 0 has them stationary, then frame 1-5, they start moving. The movement is that the dark jersey players run towards the white team, which also moves. Then they gather in the center. So the main motion is the two teams moving towards each other, converging in the middle.

Appearance: dark jerseys (maybe red or black, but the description says "dark" so maybe just dark colors), white jerseys. Number: let's see, in the first frame, maybe 8 dark and 10 white? But since it's concise, maybe just "teams of children in dark and white jerseys".

Spatial: the dark team is on one side, white on the other. They move towards each other, converging in the center. Then in frame 4, they're running towards the center, maybe. Wait, the video shows: "kids in dark and white jerseys move across the court, converging in the center. Players run towards each other, then gather in the middle."

Camera perspective: it's a top-down view, as the video is shot from above the court.

Background: minimal, just the gym with some spectators in the stands, but rules say minimal unless essential. So maybe just mention the indoor gym but not the spectators.

So the caption should be: Children in dark and white jerseys run across the indoor court, converging toward the center; the dark team moves toward the white team, who also advance, eventually gathering together. Viewed from a top-down angle with no camera movement.

Wait, check the rules. "Focus on motion and behavior in chronological order." So first, they start positioned. Then move towards each other. Then converge.

Let's structure:

Initially, children in dark and white jerseys are positioned on an indoor court. The dark-jerseyed group then moves toward the center, followed by the white-jerseyed group moving toward the dark group. As they advance, the two teams converge, running toward each other and gathering in the middle of the court. The camera remains stationary in a top-down perspective throughout.

Wait, need to check the exact frames. The first frame (0.0) shows them standing. Then frame 1, they start moving. So "initially stationary, then moving towards each other and converging."

Let's rephrase concisely:

Children in dark and white jerseys begin positioned on an indoor court, then run toward each other across the court; the dark-jerseyed group moves toward the center while the white-jerseyed group advances from the opposite side, converging as they move. The camera provides a top-down view with no movement.

Check for conciseness. The key elements: motion (run toward each other, converge), groups (dark and white jerseys), spatial (moving toward each other), camera (top-down).

Make sure not to mention background details like spectators unless essential. Since the background is a gym, but maybe the court lines are relevant. The court is wooden, but maybe that's too specific.

Wait, the rules say "minimal background unless essential". The essential for understanding motion might be the court, but since it's an indoor gym, the court is part of the setting. But the caption should be concise.

Final version:

Children in dark and white jerseys run across an indoor court toward each other; the dark-jerseyed

Basketball players are moving: running, dribbling, passing, and engaging in game play. These are solid, distinct objects moving due to physical locomotion and interactions.

The background (walls, floor) is static with no uniform shifting. No fire, water, smoke, or wind effects observed.


tags.  Finalize:  <caption_output>A live concert features a band on stage with musicians playing instruments under bright lights, while a large crowd in front dances and raises their arms. Over time, the crowd's movements intensify, with arms waving and bodies swaying rhythmically. The camera, positioned among the audience, captures the dynamic scene with slight motion as the crowd shifts, emphasizing the energetic atmosphere.

RAW CAPTION: Got it, let's see. The video starts with two people on a wooden deck. First, the person in red and white shirt is moving, then the person in pink is also moving. They seem to be playing or throwing something. Wait, the first frame: a person in red (maybe shirt) and white pants? Wait, frame 0: a person in red is moving, then frame 1: another person in pink. Wait, let's check the frames.

Frame 0: A person in red and white (maybe shirt and pants) is walking on the deck. Then frame 1: same person in red and white, and another person in pink (shorts?) moving. Wait, the video description says: first frame has a person in red (maybe shirt), then in frame 1, two people: one in red and white, one in pink. Then they move, and in frame 4, a person in blue is visible. Wait, the video shows movement: two people (one in red, one in pink) on the deck. They are throwing or catching something? Wait, the frames show the person in pink bending down, then moving. Then in frame 2, the person in red is moving, the pink person is in the background. Then frame 3: the person in pink is lying down? Wait, no, the description says in frame 3, a person in pink is bending. Then frame 4: the person in blue is entering the frame.

Wait, let's break it down chronologically. The video starts with two people on a wooden deck. First, a person in a red shirt and dark pants (from frame 0). Then in frame 1, the same person in red, and another person in pink (shorts) is moving. Then frame 2: person in red is moving away, person in pink is moving towards the right. Frame 3: the person in pink is bending down, then in frame 4, a person in a white shirt and blue shorts runs in, then exits. Then frame 5: the deck is empty except for some items.

Wait, the main subjects: two people initially (red and pink), then a third person in white and blue enters. But wait, the video description says: first frame (0.0s): a person in red (maybe shirt) moving. Then frame 1: a person in red and white (shirt) and a person in pink (shorts) on the deck. Then frame 2: person in red moves left, pink person moves right. Frame 3: pink person is bending down, then in frame 4, a person in white and blue runs in. Then the deck is empty.

Wait, the captions should be concise, chronological. So first, two people: one in red (shirt) and one in pink (shorts) are on the deck. They move; the red-shirted person walks, the pink-shirted person moves around. Then, a third person in white shirt and blue shorts enters from the right, runs across the deck, and exits. The camera is stationary, looking at the deck, with a brick wall and windows in the background. The background is minimal, so focus on the people's movements.

Wait, the problem says: "Focus primarily on the motion and behavior of main subjects (people/animals/objects) in chronological order."

So step by step:

0.0s: Person in red (shirt, dark pants) and another person (pink shirt, dark pants) are visible on a wooden deck.

1.0s: Person in red and white shirt is moving left; person in pink is bending down and moving right.

2.0s: Person in red moves further left; person in pink is moving right, then bends down.

3.0s: Person in pink is lying on the deck? No, the description says "bending" maybe. Wait, frame 3: "a person in pink is bending down" then frame 4: "a person in white and blue shorts" is visible.

Wait, maybe better to track:

First, two people: one in red and white (shirt and pants), one in pink (shirt and pants) on the wooden deck. They are moving: red-shirted person walks, pink-shirted person moves and bends down. Then a third person in white shirt and blue shorts runs in from the right, crosses the deck, and exits. The deck is empty at the end.

But need to describe appearance: red-shirted person, pink-shirted person, then white and blue shorts person.

Also, spatial relationships: the two people are on the deck, the red one is to the left, pink to the right. Then the third person comes from the right.

Camera perspective: stationary, looking at the deck (no movement mentioned, so probably static

Two people (a child in pink and an adult in white) are moving: the child runs, falls, and gets up; the adult moves with a box and then walks. These are discrete solid objects moving due to locomotion and collisions.

The background (walls, windows, wooden deck) is static with no shifting or fluid motion. No fire, water, smoke, or wind observed.


Two men sit opposite each other at a table. The man in a light shirt gestures with both hands while speaking, then raises his right hand toward his face and continues gesturing. The man in a dark suit sits with hands clasped, listening. The camera remains stationary.

Two people are seated at a table, exhibiting gestural motion (hand movements) consistent with human locomotion and interaction.

The background elements (TV screen, walls) show no shifting or fluid motion; no fire, water, smoke, or wind is present.


Two individuals in gray shirts interact with a colorful volleyball. The person in black shorts throws the ball, prompting the person in black pants to move toward the glass wall; the ball strikes the wall, and they reposition, with the original thrower holding the ball again. The camera follows their motion with minimal background detail, maintaining a steady perspective as the subjects shift positions and interact with the ball.

Two individuals (player and receiver) and a volleyball move through distinct physical interactions: serving, hitting, and ball trajectory.

Static building elements (glass windows, concrete floor) show no uniform shifting; no fire, water, smoke, or wind effects are present.


A man in a pink shirt stands at a kitchen counter, holding a green container and pouring its contents into a yellow cup; he shifts slightly while pouring, with wooden cabinets and a decorative fleur-de-lis wall piece visible in the background. The camera remains static throughout the sequence.

The man is moving his arms and hands while handling objects on the kitchen counter, including a yellow container. His motion is deliberate and confined to upper body movements without large-scale locomotion.

The background (wooden cabinets, door with decorative panel, ceiling) remains static with no shifting or fluid motion. No fire, water, smoke, or wind is present in the scene.


A woman with dark hair and a sleeveless purple top lies on a bed, interacting with a child in a pink dress who sits on the white bedspread. The woman reaches out to the child, whose arms and legs shift as she guides their movements; the child moves slightly, turning toward the woman while maintaining seated position. The woman adjusts her posture, turning to face the child, who remains on the bed near a small yellow object. The background is a dimly lit room with minimal visible furnishings. The camera remains stationary in a fixed medium shot, capturing the interaction from a consistent angle.

Two discrete solid objects (adult and child) are moving: the child actively reaches toward the adult, shifts position on the bed, and moves arms; the adult responds with head turns and arm movements to interact with the child.

The background elements (bed, pillow, walls) remain static with no uniform shifting or environmental fluid motion (fire, water, smoke, wind). The scene is dark but lacks ambient environmental cues.


A bald, naked baby sits in a stainless steel kitchen sink, moving hands to splash water; colorful toys are visible in the sink. The baby shifts position slightly, interacting with the water. The camera maintains a static top-down perspective throughout.

The baby is the only discrete object; it moves by turning its head, moving arms, and shifting its body due to intentional locomotion.

Background elements (sink, faucet, window, countertop) are static with no uniform shifting. Water in the sink is still, showing no fluid motion (fire, waves, smoke, or wind), so no ambient environmental motion.


A police officer in a gray shirt and black "POLICE" vest walks alongside a person in an orange shirt with long dark hair along a light-colored building's exterior sidewalk. The officer moves slightly ahead and to the right of the person, who walks beside him, both progressing forward in the same direction. The camera follows their movement steadily, maintaining a medium shot that captures their side-by-side motion against the building and surrounding greenery.

Two distinct human subjects (a person in an orange shirt and a person in a police vest) are moving forward along the sidewalk. Their motion is due to explicit locomotion (walking), with clear bounding box tracking.

The background (building walls, sidewalk, greenery) shows no significant shifting or fluid motion. There is no fire, water, smoke, or wind-driven motion visible. Minor tree sway is negligible and not dominant.


RAW CAPTION: Got it, let's tackle this. First, I need to describe the video chronologically. The main subjects are the people on stage. Let's see the sequence.

In the first frame, there's a group on stage: a man in a dark suit with a pink item (maybe a trophy), another man in a dark suit with a bow tie, a woman in a pink dress, and others. The background has a large screen with projections, and an audience is visible. Then, the second frame shows the group shifting—maybe the man with the pink item is moving, and the woman in pink is interacting. The third frame, the group is repositioning, with the woman in pink being attended to. Then the fourth frame, more movement as people adjust positions. The fifth frame shows them standing together, maybe posing or accepting something.

Need to focus on motion and behavior. Let's outline:

- Initial scene: Multiple people on stage (men in dark suits, one in bow tie, woman in pink dress) interact near a podium. The woman in pink is next to a man holding a pinkish object. The background screen shows images, audience is in shadow.

- As time progresses, they shift positions: the man with the object moves, others adjust. The woman in pink is being handed something or adjusting her dress. Then they stand in a line, possibly accepting an award.

- Spatial relationships: the podium is to the right, screen behind. Audience is in front (silhouettes).

- Camera perspective: probably a fixed shot from the audience side, capturing the stage.

Need to be concise, chronological. Exclude text recognition (like "Eurovision" but the problem says exclude named characters, so skip any logos if they're named, but the podium has a logo, but rule f says exclude named characters or text recognition. So don't mention the logo. Focus on appearance: people's clothes.

Let me structure:

At the beginning, a group of individuals stands on a stage: several men in dark suits, one with a bow tie, and a woman in a bright pink dress. They interact near a podium. The woman in pink moves closer to a man holding a pink item, and the group adjusts positions, with some individuals shifting to the left and right. The background screen displays dynamic images, while audience members observe. The camera remains stationary, capturing the stage from a frontal angle with a slight shake.

Wait, need to check the rules. Rule g says think internally but don't output reasoning. So focus on the sequence.

First, the main subjects: the group on stage. Their actions: initially, they are grouped together, then the man with the pink item moves, the woman in pink adjusts, others move. Then they form a line.

Wait, let's look at the frames:

Frame 0: Stage with people: man (dark suit) holding pink object, man (dark suit bow tie), woman (pink dress), other man (dark suit), near podium. Screen behind shows projection.

Frame 1: People shifting; the man with pink item is still holding, others moving.

Frame 2: Group is now more together, maybe the woman in pink is being handed something, the man with the object moves away slightly.

Frame 3: The group is closer, possibly interacting.

Frame 4: They stand together, maybe posing for the audience.

So the chronology:

1. A group of individuals (men in dark suits, one with a bow tie, woman in bright pink dress) on stage interact near a podium.

2. The woman in pink adjusts her position, moving closer to a man holding a pink object.

3. The group shifts positions, some individuals stepping to the left and right.

4. The group eventually forms a line, standing still as they interact.

Background: large screen with projected images, audience in dark (silhouettes).

Camera: fixed position, frontal view, slight shake.

Now, structure into a concise paragraph.

"Several individuals stand on a stage: men in dark suits, one wearing a bow tie, and a woman in a bright pink dress. The woman in pink moves closer to a man holding a pink object, while others adjust positions, shifting left and right. The group forms a line, interacting near the podium as the background screen displays dynamic images. The camera remains stationary, capturing the scene from a frontal angle with a subtle shake."

Check rules:

a) Motion and behavior chronologically: yes, sequence of actions.

b) Appearance and number: men in dark suits (multiple), woman in pink (one), etc.

c) Spatial: group near podium, screen behind, audience in front.

d) Camera: stationary, frontal, slight shake.

e) Background minimal: mention screen and audience as silhouettes, but rule e says minimal unless essential. The screen is essential for context (dynamic images), audience for setting.

f) Exclude text

Multiple solid human subjects (people) on stage exhibiting distinct motion (handshakes, position adjustments, walking) within the frame.

No significant fluid/environmental motion (fire, water, smoke, wind) detected. Background elements (stage, screen) show projected content movement but no uniform physical environmental flow.


RAW CAPTION: Got it, let's tackle this. First, the video shows a person using a snow blower. Let's check the frames.

Frame 0: Person is pushing a snow blower on a snowy driveway. They're in front of the car, wearing dark clothes, maybe a jacket. The snow blower is black or dark, and they're moving it to clear snow.

Frame 1: The person is still using the snow blower, maybe pushing it forward. The snow is being thrown, so they're clearing the path.

Frame 2: The person steps back, maybe turning the blower. Then another person (maybe in blue pants) comes into view. Wait, the main subject is the first person.

Frame 3: The first person walks away from the blower, then the second person (in blue pants) comes into the scene, possibly moving the blower or something. Wait, no, maybe the first person moves to the right, and the other person is on the left. Wait, the video shows the person operating the snow blower, then they stop, walk away, and then the snow blower is moved or another person steps in.

Wait, let's look at the sequence:

Start: Person on a snow blower, pushing it along the driveway (from the car's perspective). They're moving forward, clearing snow. Then, the person turns around (frame 2-3), maybe stepping back. Then frame 4: Person in blue pants walks in, but maybe the first person is still there. Wait, maybe the main subject is the person with the snow blower.

Chronological order:

1. Person (wearing dark winter clothing) pushes a black snow blower across a snow-covered driveway, clearing a path. The driveway is in front of houses with snow-covered roofs.

2. The person stops pushing, turns the snow blower, and walks away from the blower towards the right side of the frame.

3. Another individual (wearing blue pants) enters the scene, moving from the right towards the left, possibly assisting or moving the blower.

Wait, in frame 0, the person is moving the blower. Frame 1: person is still on the blower. Frame 2: person steps away, maybe the blower is being moved. Frame 3: person is walking, and the blower is on the snow. Frame 4: the person continues walking, and another person (blue pants) comes into view.

Wait, the video has 5 frames. Let's see:

Frame 0: Person with snow blower pushing forward.

Frame 1: Person moving the blower, clearing snow.

Frame 2: Person stops, walks away from the blower towards the left (or right?), and another person (blue pants) enters from the right.

Frame 3: The first person is walking away, and the second person (blue pants) is near the blower.

Frame 4: The first person is further away, and the second person is moving the blower or something.

Wait, the main subject is the person with the snow blower. Let's focus on their motion.

The person operates the snow blower along a snow-covered driveway, clearing a path. They move the blower forward, then stop and step back, turning the blower. Then another person (blue pants) enters and moves towards the blower.

But need to be concise. Let's structure it:

A person in dark winter clothing uses a black snow blower to clear snow from a driveway. They push the blower forward, then stop and walk away, turning the blower. A second person in blue pants approaches from the right, moving the blower or assisting. The scene is viewed from inside a car, with minimal camera movement.

Wait, check the rules: minimal background, focus on motion. So:

The person pushes a snow blower along the snowy driveway, clearing a path. They step back, turn the blower, and walk away. A second individual in blue pants enters, moving the blower toward the right. The video is shot from a car’s perspective, with slight movement.

Wait, the camera is from inside a car, looking out, so perspective is "from inside a car."

Let me check the frames:

Frame 0: Person pushing blower towards the camera (since it's from the car's view, the person is approaching). Wait, the car is parked, so the driveway is in front of the car. So the person is moving towards the car's direction? Wait, no: in frame 0, the person is on the driveway, pushing the blower. Then in frame 1, the person moves forward. Wait, maybe the person is moving the blower away from the car. Wait

A person operating a snow blower is moving across the snowy driveway. The snow blower machine is also moving, and both the person and the machine are distinct solid objects.

The background (houses and snow-covered ground) remains static throughout the video. There is no fluid motion (fire, water, smoke, or wind-driven effects) dominating the scene. The snow being blown is an effect of the snow blower and is not considered ambient.


Two uniformed officers in dark blue uniforms with hats stand at attention, saluting; one officer is positioned to the left of a covered coffin draped with an American flag, while the other officer stands to the right of the coffin. In the foreground, attendees face the officers, including a person with curly hair wearing a blue jacket and another individual in a black jacket. The camera remains stationary, capturing the scene from behind the attendees.

The audience members (e.g., the person with curly hair and the person in the blue jacket) exhibit minor movements (turning heads, shifting posture). The uniformed individuals remain stationary.

The background (stone wall, door) is static and unchanging. No fluid or environmental motion (fire, water, wind) is present.


A person in a yellow shirt and jeans kneels on a wooden floor, holding a long yellow balloon; they stretch and twist the balloon while other colorful balloons (red, green) rest on a table to their left. The background includes a bookshelf and small cabinet, and the camera remains stationary.

A person is actively manipulating a long, flexible object (e.g., balloon or tube) with hand movements, indicating intentional physical interaction.

Background elements (furniture, walls) show no uniform shifting, no fire/water/smoke/wind present.


RAW CAPTION: Got it, let's tackle this captioning task. First, I need to look at the video frames provided. The main subject is a child ironing. Let's break down each part.

In the first frame, the child is leaning over a pink ironing board. The child has a gray long-sleeve shirt and a black-and-white patterned skirt. The iron is pink, and the item being ironed is yellow. The ironing board has a pink frame with a colorful mat. There are other items: a white cloth and maybe some clothes. The background has a blue bed with a stuffed bear, white dresser, and a chair.

Now, the video shows the child moving the iron over the yellow fabric. The action is ironing, so motion is pressing the iron on the fabric. The child's hands: one holding the iron, the other adjusting the fabric.

Chronological order: start with the child ironing, then moving the iron across the fabric. The camera starts with a wider shot, then zooms in on the hands and the ironing board. So the camera movement is a slight zoom or focus shift.

Need to mention appearance: child (gender not specified, but from the video, a girl), gray top, patterned skirt, pink iron, yellow fabric. The ironing board is pink. Background elements: bed with blue sheet, stuffed bear, white dresser—minimal background as per rules.

Check rules: focus on motion (ironing, moving iron), behavior (child is ironing), chronological order (start ironing, then moving). Spatial: the child is in front of the bed, the ironing board is between the child and the dresser.

Excluding text recognition, named characters, so no names. Keep background minimal. Camera perspective: starts at a medium shot, then zooms in to close-up of the hands and ironing board.

Putting it together:

A child in a gray long-sleeve shirt and black-and-white skirt irons a yellow fabric on a pink ironing board with a colorful mat. The child moves a pink toy iron across the fabric, adjusting it with their other hand. The camera zooms in to focus on the child's hands and the ironing board, showing the yellow item, white cloth, and striped fabric on the board. Background includes a blue bed with a stuffed bear and white furniture, kept minimal.

Wait, check rules: "conclude with camera perspective and movement". So after describing the action, mention camera. Also, keep concise.

Let me structure it:

A child wearing a gray long-sleeve shirt and a black-and-white patterned skirt irons a yellow fabric on a pink ironing board with a colorful mat. The child moves a pink toy iron over the fabric, using their left hand to adjust the cloth. The camera zooms in to a close-up of the ironing board, revealing additional items like a white cloth and striped fabric. Background elements are minimal, featuring a blue bed and white dresser.

Check chronological: starts with ironing, then moving the iron, then camera zoom. Yes.

Make it concise. Let's draft:

A child in a gray top and black-and-white skirt irons a yellow fabric on a pink ironing board with a colorful mat. The child moves a pink toy iron across the fabric, adjusting it with their other hand. The camera zooms in to show the ironing board, including a white cloth and striped fabric. Background includes a blue bed and white dresser.

Wait, the rule says "briefly describe their appearance and number". The child is one. The iron is pink, yellow fabric. Ironing board pink.

"Focus primarily on motion and behavior in chronological order": the action is ironing, then moving the iron.

"Mention spatial relationships if relevant": the child is in front of the bed, but maybe not necessary. The ironing board is where the action is.

"Conclude with camera perspective and movement": the camera zooms in.

Let me make sure it's concise. Maybe:

A child wearing a gray long-sleeve shirt and black-and-white skirt irons a yellow fabric on a pink ironing board. The child moves a pink toy iron across the fabric, adjusting it with their left hand. The camera zooms in to a close-up of the ironing board, showing a white cloth and striped fabric on the mat. Background features a blue bed and white dresser.

Yes, that's good. Check all rules:

a) Motion: ironing, moving iron, adjusting. Chronological: starts with ironing, then moving.

b) Appearance: gray top, black-and-white skirt, pink iron, yellow fabric, pink board.

c) Spatial: the child is using the board, board has items.

d) Camera: zooms in to close-up.

e) Background minimal: blue bed, white dresser.

f) Exclude text, names.

A child is actively moving a toy iron across a piece of clothing on an ironing board; both the iron and the clothing exhibit discrete, solid motion due to the child's deliberate hand movements.

The blue bed, white dresser, and green wall remain stationary throughout the video, with no fluid motion (fire, water, smoke) observed in the environment.


A small child wearing yellow goggles and holding a toy gun stands in front of a wooden counter, with two adults positioned behind. The child steps forward slightly, then steps backward while the adults adjust their positions, remaining close by. The camera remains stationary, capturing the scene through a mirror reflection.

A child wearing a yellow helmet is being held by an adult, and another person in the background is walking away. These movements are due to locomotion and physical interactions.

No fire, water, smoke, or wind. Background elements (wooden structure, walls) are static and do not shift uniformly.


Participants in bright orange and white polar bear-themed suits run energetically toward a pool, arms raised, as they cheer and interact with one another; several individuals in similar costumes transition into the water near a large inflatable polar bear adorned with a green scarf, positioned prominently in the background; the camera shifts from close-up shots of the group to a wider view capturing the poolside activity and the inflatable structure, maintaining a dynamic perspective with slight movement to follow the participants' motion.

People in orange costumes are dancing with visible arm movements and body motion, representing discrete solid objects moving due to locomotion.

Background elements (structures, pool area) show no uniform shifting; water in the pool is calm with no visible fluid motion (fire, smoke, waves), and no wind-driven effects.


RAW CAPTION: Got it, let's tackle this. First, the video is a classroom scene. The main subject is a person in a dark blue shirt sitting at a desk. They're turning their head to the right, then left, and looking around. There are other students: a red-haired person, others in the background. The camera moves from left to right, panning across the room. Let's check the rules. Need to describe motion in chronological order. Start with the main person's actions: turning, then maybe smiling? Wait, in the frames, the person in dark shirt turns their head, looks around. Others are seated, some working. The camera moves slightly, panning. Background has posters on walls, but minimal. So:

In a classroom, a person in a dark blue shirt turns their head to the right, then left, looking around while seated at a desk. Other students, including one with red hair, remain seated at desks, some working. The camera pans slightly from left to right across the room, capturing the movement of the main subject and the surrounding students. Background elements are minimal, featuring wall posters.

Wait, need to be concise. Let's check the steps. Chronological order: first, the person turns head (from frame 0 to 3), then looks around, maybe smiles (frame 4-5). The camera movement is panning left? Wait, the video shows the camera moving from left to right as it follows the main subject. Let's see the frames: starts with someone's back, then camera moves to show the person in dark shirt, then pans up. So camera is panning across the room, moving to show different angles.

Let me rephrase. The main subject (person in dark blue shirt) is seated, turns their head to the right, then left, and looks toward the camera, smiling. Other students are seated at desks, some writing or working. The camera moves slowly from left to right, capturing the main subject's head movements and the classroom environment. Background includes wall posters and fluorescent lights.

Wait, the rules say minimal background. So mention only essential. Let's make it concise:

A person in a dark blue shirt turns their head to the right, then left, looking around and smiling while seated at a desk. Other students, including one with red hair, remain seated at desks, some working. The camera pans slightly from left to right across the room, focusing on the main subject's movements.

Check if that's chronological: first the turn to right, then left, then smile. The camera moves left to right. Other students are stationary. Yes. Now, check all rules. Appearance: dark blue shirt, red hair. Number: multiple students, but focus on main subject. Spatial: main subject in front, others in background. Camera movement: pan left to right. Background minimal, posters not essential unless needed. Since it's a classroom, maybe necessary for context, but rules say minimal. So maybe just mention "classroom setting" without details.

Wait, the example in the problem statement says "keep background descriptions minimal unless essential for understanding motion." So the classroom is the setting, but the posters aren't essential for motion, so maybe not mention. Let's see: the motion is people sitting and moving their heads. So background is classroom walls, but not essential.

So final caption:

In a classroom, a person in a dark blue shirt turns their head to the right, then left, looking around and smiling while seated at a desk. Other students remain seated, some working at their desks. The camera pans slowly from left to right across the room, capturing the main subject's head movements.

Wait, "turns to the right, then left" is chronological. The main subject's actions. Camera movement is from left to right. Yes. Check if all rules are followed: motion and behavior in order, appearance (dark blue shirt), number (multiple students), spatial (seated at desks), camera perspective (pan left to right), background minimal (just "classroom" without posters). The "others remain seated" is spatial. Yes.

Let me confirm the video: the first few frames show the person from behind, then turning to right, then left, smiling. Camera moves along the row of desks. So the pan is to the right as it follows the person. So "camera pans slowly from left to right".

Yes. So the caption should be:

In a classroom, a person wearing a dark blue shirt turns their head to the right, then left, looking around and smiling while seated at a desk. Other students remain seated at desks, some working. The camera pans slowly from left to right across the room, focusing on the main subject's movements.

Check conciseness. Maybe shorten "wearing a dark blue shirt" to "in a dark blue shirt". "Looking around and smiling" is part of their behavior

Multiple students are moving: the foreground student (dark shirt, backpack) turns head and body while others in the background adjust posture or write. These are discrete solid objects moving due to intentional locomotion (e.g., head turns, hand movements).

No shifting backgrounds or fluid/environmental motion observed; walls, ceiling, and fixed decorations remain stable throughout the clip. No fire, water, smoke, or wind elements present.


In a barber shop with checkered flooring, a seated individual wearing a blue cape, white socks, and dark shoes remains still in a chair while a standing person in a black shirt and jeans approaches from the side, adjusts the seated person's hair, and then steps back. The standing person moves slightly to the left and right of the seated individual throughout the sequence. The camera maintains a static, front-facing perspective with minimal movement.

The barber (standing) and the seated customer (in a chair) exhibit controlled movement. The barber shifts position slightly while working, indicating deliberate physical locomotion of solid objects.

The background elements (walls, cabinets, checkered floor) are static with no shifting or environmental fluid motion (fire, water, wind) observed.


Two women sit side by side; the woman in pink (left) extends her hand toward the woman in gray with a pink headscarf (right) holding a white plastic bag. The camera remains static throughout.

Two people are present: the individual in pink exhibits hand gestures and body movement, while the individual in gray manipulates a white paper and moves their hands. Both motions are discrete, solid-object actions involving muscle-driven movements.

The background consists of a static orange curtain and wall with no shifting or environmental motion (fire, water, wind). The curtain and wall remain fixed throughout the sequence, indicating no ambient environmental effects.


A hand with bright purple nail polish holds a gold-handled makeup brush, applying a streak of green eyeshadow across the lower eyelid of a partially closed eye. The brush moves horizontally from left to right, blending the color onto the eyelid. The camera maintains a tight close-up, focusing on the eye and brush, with the background remaining indistinct.

A hand with purple nail polish and an eyeshadow brush is moving across the eyelid to apply makeup. The brush and hand are discrete solid objects moving due to explicit physical action (applying eyeshadow).

No shifting backgrounds or fluid/environmental motion (fire, water, wind) detected. The background consists of static facial features (eyebrow, eyelid) with no uniform movement.


A person in a white shirt and light blue jeans throws an object toward a red target with white dots mounted on a tree stump, then walks toward the target. The camera remains stationary, capturing the motion from a fixed angle.

A person in a white shirt and jeans is moving: throwing an object (inferred) and then running towards the target.

The background (trees, grass, dirt path) is static with no significant environmental motion. No fire, water, smoke, or wind are present.


RAW CAPTION: Got it, let's tackle this. The video shows a woman in a park doing an exercise. First, she's lying on her back on a mat. Then she moves her right leg up, bends it, and grabs her ankle. Let's check the rules.

Main subject: a woman. Appearance: pink workout clothes, blonde hair. She's lying on a blue mat. Actions: starts lying still, then lifts right leg, bends knee, reaches to touch ankle. Background is grass, trees, fence but minimal. Camera is static, top-down maybe? Wait, the video is outdoors, shot from above? The first frames show her from behind, so camera is probably fixed, maybe slightly elevated but not moving.

Chronological order: she's lying down, then moves her leg. So the caption should start with her position, then the movement. Mention spatial: she's on a mat on grass. Background minimal, so don't describe much. Camera perspective: static, overhead? Wait, the video is a still shot, so camera is stationary, maybe top-down.

Let me structure it. "A woman in pink athletic wear lies prone on a blue yoga mat in a grassy park area. She remains still for a few seconds, then lifts her right leg, bending the knee and reaching back to grasp her ankle. The camera maintains a static overhead perspective throughout the sequence, capturing minimal background details of trees and a distant fence." Wait, but the background is not essential, so maybe skip the background. Rules say minimal background unless essential for understanding motion. The motion is the leg movement, so background not needed. So focus on the woman's actions.

Wait, the initial frames: she's lying on her back (prone? No, prone is face down, but she's lying on her back, so supine). Wait, supine. So "lies supine on a blue mat." Then her movement: lifts right leg, bends knee, grabs ankle. So chronological: starts lying still, then lifts right leg to bring knee toward chest.

Check appearance: pink leggings, pink sports bra, white shoes. Number: one person. Spatial: on mat, grassy area.

Camera: static, no movement. So "The camera remains stationary, providing a fixed perspective."

Putting it all together concisely.

"A woman in pink athletic attire and white shoes lies supine on a blue yoga mat in a grassy park. She holds a still position for several frames, then lifts her right leg, bends the knee, and reaches back to grasp her ankle. The camera maintains a static overhead view throughout, with minimal background elements visible."

Wait, but the rules say "conclude with the camera perspective and movement". So "static overhead" is the perspective. Let's see if that's accurate. The video is shot from above, I think, because we can see the entire body and the ground. So static, overhead.

Check if background is essential. The motion is the leg movement, so background not necessary. So maybe exclude the park details. Wait, rule e: "keep background descriptions minimal unless essential for understanding motion". The motion is the exercise, so the park background isn't essential, so just mention it if needed. But in this case, the exercise is on the grass, so maybe "on a grassy area" is enough, but minimal.

So revised: "A woman in pink leggings, a pink sports bra, and white shoes lies supine on a blue yoga mat in a grassy area. She holds a still position before lifting her right leg, bending the knee, and reaching back to grasp her ankle. The camera remains stationary with a fixed overhead perspective."

Wait, the rules say "briefly describe their appearance and number". So color, size, orientation. The woman is in pink, so that's part of appearance. Orientation: supine.

Also, chronological order. So first, lying still, then moving.

Let me check the video frames. The first few frames (0-3 seconds) she's lying still, then at frame 4 she starts lifting her leg, frame 5 she's holding the pose.

So the caption should say she holds still, then lifts leg.

Now, the output must be concise. Let's condense.

"A woman in pink athletic wear lies supine on a blue yoga mat. She remains motionless for several seconds before lifting her right leg, bending the knee, and reaching back to grasp her ankle. The camera maintains a static overhead view."

That's concise. Check all rules: motion in chronological order (still, then lift leg), appearance (pink, blue mat), spatial (on mat), camera (static overhead). Background minimal. No text, no named characters. Good.

A person in pink attire is performing a yoga pose, moving from a supine position to an extended pose (e.g., forward bend or plank). The motion is controlled and deliberate, indicating physical locomotion.

The background (trees, fence, grass) is stable with no shifting or fluid motion. No fire, water, smoke, or wind is visible. Ambient environmental motion is absent.


A person wearing a dark shirt with a white skull pattern plays a black clarinet, their left hand pressing keys while the right hand adjusts finger positions. The clarinet is held vertically in front of them, with a beige pillow and brown curtains visible in the background. The camera maintains a close-up, slightly shaky perspective focused on the hands and instrument.

Hands manipulating a clarinet exhibit discrete, deliberate movements (finger positioning, embouchure adjustments) consistent with playing a wind instrument.

Background elements (e.g., patterned fabric, cardboard) show no significant shifting or fluid motion; no fire, water, or smoke present.


A person in a black-and-white striped long-sleeve shirt pours leafy greens into a blender on a table in a greenhouse. The camera zooms in to show the blender filling with greens, blackberries, and red fruit, then the ingredients blend into a green mixture. Rows of plants line the greenhouse background.

Discrete solid objects (berries, greens, and the blender base) exhibit motion due to the blender's mechanical mixing action, with contents swirling and blending inside a stationary container.

Background elements (greenhouse structure, plants) remain static with no uniform shifting or fluid motion (e.g., no fire, water, or wind dominance).


Three individuals in a gym: a central person in a light shirt and shorts holds a barbell overhead with arms raised, flanked by two others—one in a beige top and dark pants, the other in a light green shirt and dark pants—both with hands raised. The central person lowers the barbell to waist height, then bends forward to drop it, while the assistants step back and move out of the way. The camera remains static throughout, capturing the scene from a fixed, eye-level perspective.

Three people: central figure lifts/lowers a barbell, then steps backward; side figures adjust positions. Solid objects (people, barbell) move due to explicit physical forces (lifting, stepping).

Background (plain wall, floor) shows no uniform shifting or fluid motion; no fire, water, smoke, or wind detected.


The video opens with five individuals seated around a poker table, engaged in gameplay. The camera zooms in on a person in a green shirt, resting their chin on their hand and looking downward. It then shifts to a close-up of another individual wearing a black and white jacket, facing slightly to the right. The camera movement transitions from a wide-angle view of the table to focused close-ups of the subjects, maintaining minimal background context.

Discrete solid objects (people at a poker table) exhibit motion: the person in the green shirt subtly moves their hand from their chin, and the person in the black shirt with stripes moves their head and mouth while speaking.

No shifting background or fluid motion (fire, water, wind). The background features static indoor elements (walls, furniture) that remain unchanged throughout the sequence.


A woman in a blue tank top and denim shorts stands in a living room, holding an object and extending her arm toward a black and white dog. The dog runs toward her, leaps into the air, and lands on a nearby couch. The camera remains static, capturing the scene from a fixed position.

A woman and a dog are moving; the dog jumps and interacts with the couch, while the woman gestures and shifts position (e.g., throwing an object).

Background elements (walls, doors, couch) are static; no shifting or fluid/environmental motion (fire, water, smoke, wind) observed.


A group of five people in a dimly lit room interact around a long, dark tube held aloft by two individuals—one in a white t-shirt and jeans, the other in a white t-shirt and khaki shorts. The group shifts positions: a person in a gray shirt uses a white cloth near their face, while others gesture or adjust their stance. The scene occurs near a mirror and table with bottles, with the camera remaining stationary but slightly shaky, capturing their collaborative motion.

Multiple people (at least 5) are moving: holding and manipulating a long pole, shifting positions, and one person is seen sitting and then standing. The motion is due to explicit physical interactions (pulling, pushing).

No shifting background elements. No fire, water, smoke, or wind. Background (walls, painting) is static.


A person in a red shirt and dark pants sits on a wooden chair, holding a saxophone. They adjust their grip on the instrument, looking toward the camera and then slightly to the side, with a music stand holding sheet music positioned to their left. The scene is viewed from a fixed camera angle with a slight shake, capturing the individual's movements against a plain wall and window with framed items in the background.

A person in a red shirt is actively manipulating a guitar, with visible hand movements and body shifts corresponding to playing the instrument.

Background elements (walls, framed pictures, chairs) show no shifting or environmental fluid motion (fire, water, smoke, wind); background remains stationary across frames.


A bald man in a checkered shirt stands near a window with a tall bottle, holding an object, then the screen cuts to black. He pours liquid from a bottle into a container at a cluttered desk with food and office supplies. Finally, he sits across from a person wearing a cap at the desk, engaging in conversation.

The man manipulates discrete objects: opening a wine bottle with a corkscrew, pouring liquid into a glass, drinking, and interacting with another person (wearing a cap). The bottle, glass, and corkscrew exhibit explicit physical motion due to manual actions.

The background in the office scene (from 1.3s onwards) is static with no shifting elements (walls, window blinds, printer). No ambient environmental motion (fire, water, wind, smoke) is present. The initial scene (0.0-0.8s) shows a brief transition but no fluid environmental motion.


A woman in a green top and dark capris performs fluid dance movements across a wooden gym floor, extending her arms and legs in sequential steps and turns while gliding around the space; the camera tracks her motion with a slight pan.

The dancer is the only discrete solid object moving, performing locomotion (dancing) with steps, kicks, and extensions.

The background (wall with splatter patterns and ballet barre) is stationary; no fluid or environmental motion (fire, water, smoke, wind) is present.


A person in a red shirt enters a car through the open driver's side door, moving toward the steering wheel while holding an object. The camera remains stationary, capturing the interior of the vehicle with minimal background detail.

A person in a red shirt is moving their hands and arms within the car interior, interacting with objects (e.g., steering wheel, dashboard).

Background elements (car exterior, distant structures) show no significant uniform shifting; no fire, water, smoke, or wind motion detected.


A boy in a light-colored shirt sits on the floor, extending his hand to touch the paw of a medium-sized, fluffy brown-and-white dog sitting in front of him. The boy moves his hands toward the dog, then pulls back while the dog remains stationary. Scattered balloons and furniture are visible in the background. The camera maintains a fixed, eye-level perspective throughout.

A child and a dog interact: the child extends and retracts their arm toward the dog, while the dog moves its head and body in response; balloons are static or minimally displaced but not the primary motion source.

Background elements (bed, walls, furniture) remain stationary across frames; no fluid motion (fire, water, smoke) or significant environmental movement observed.


A wooden table holds a stacked decorative box with red and purple patterns and scattered cards. Two light-skinned hands enter the frame, moving a card left, then grasp the box to rotate it, revealing different sides. The camera maintains a top-down perspective with slight motion as the hands interact with the box.

A human hand interacts with a wrapped package, manipulating it to open and extract objects. The hand's motion is deliberate and driven by physical interaction with the package.

Background elements (wooden table, chair, window) remain stationary and show no uniform shifting or fluid environmental motion (e.g., no fire, water, or wind effects).


A person wearing dark pants and a green shirt enters the frame from the right, steps onto the wooden deck supported by black pedestal bases, and then walks away to the right. The camera remains stationary, providing a top-down view of the deck against a brick wall.

A person (wearing green shirt and dark pants) moves a wooden board with black rubber feet; the person steps on and pushes the board, causing discrete motion of both the person and the board.

The brick wall and concrete floor background shows no uniform shifting or movement. No fire, water, smoke, or wind is present; the environment is static.


RAW CAPTION: Got it, let's see. The video starts with a snowy path, cars on the left. Then people are sledding. First, a few sledders on the path. They're moving down the slope. The camera is following them. Let's break down the chronology.

First frame: snowy path, car on left, people in the distance. Then as the video progresses, the sledders come closer. In the later frames, they're approaching the car. The main subjects are children or people on sleds. The sleds are red and maybe other colors. They're moving from the top of the hill down towards the car.

So chronological order: Initially, sledders are far down the path. Then they move closer, approaching the car on the left. The camera is probably moving forward, following the sledders. Let's check the rules. Need to mention motion, appearance (color, number), spatial relationships.

In the first few seconds, three sledders maybe? The video shows people on sleds coming down the snow path. The first frame: a person on a red sled, then another, then more. As they approach, they get closer to the car. The car is on the left side of the path.

So the caption should start with the sledders at a distance, moving down the snowy path, approaching the car on the left. Mention the sleds (red, maybe yellow), number of people. Then the camera movement: following the sledders, maybe a slight shake? Wait, the video shows the camera moving forward as the sledders come closer.

Let's structure it:

- Initially, multiple people (children?) on sleds (red, yellow) sled down a snow-covered path from the top of a hill.
- As the video progresses, they move closer to the camera, which is positioned on the left side of the path, with a car visible.
- The sledders approach the car, with one person on a red sled coming very close to the camera.

Wait, need to count: in the frames, there are three people. Let's check the frames. Frame 0: one person. Frame 1: two. Frame 2: three. Then they come closer. So the main subjects are three people on sleds, moving down the slope.

Appearance: red and yellow sleds, maybe. Let's see the description: in frame 4, there's a red sled and a yellow one. So three people: red, yellow, and another.

Spatial: the car is on the left. The sledders are moving from top to bottom, approaching the car.

Camera: the camera is moving forward, following the sledders, so the perspective is from the path, maybe a handheld camera, slight shake? But the rule says "conclude with camera perspective and movement".

So putting it all together:

Three children on sleds (red and yellow) descend a snow-covered path from the hilltop, approaching a parked car on the left. They move closer to the camera, which captures their descent from a low angle, following their motion with slight camera shake.

Wait, check the rules: "mention spatial relationships if relevant (e.g., in front of, to the left)". So the car is to the left of the path. The sledders are moving from the top down the path.

Also, background: minimal, so just "snow-covered path, trees in background".

Wait, the rules say background descriptions minimal unless essential. So maybe just mention the path is snow-covered.

Let me draft:

Initially, three people on sleds (red and yellow) sled down a snow-covered path from the hilltop. As the video progresses, they approach a parked car on the left side of the path, moving closer to the camera. The camera follows their descent from a low angle, capturing slight motion shake.

Wait, but the first frame shows the sledders in the distance. Then they come closer. So chronological: start with sledders at the top, moving down, approaching the car.

Number: the video shows three people. In frame 3, there are three sledders. So three people.

Appearance: red and yellow sleds. Let's confirm. The frames show a red sled, a yellow sled, and another sled (maybe red or another color). So three people.

Spatial: car is on the left of the path.

Camera: moving forward, following the sledders, so camera is moving with them, maybe handheld, slight shake.

Putting it all together:

Three children on colorful sleds (red and yellow) descend a snow-covered path from the hilltop, moving toward a parked car on the left. They approach the camera, which follows their motion from a low angle with slight shake.

<caption_output>Three

A person on a sled moves down a snowy slope. The sled's movement is driven by gravity, and the person is sitting on it. The motion is smooth and follows the slope.

The background consists of snow-covered ground and trees which are static. There is no significant environmental motion (fire, water, smoke, wind) to consider.
