A player in a red jersey dribbles the basketball, then jumps to shoot toward the hoop while a player in a white jersey (number 32) stands nearby. The ball arcs through the basketball hoop, and the white jersey player moves afterward. The camera tracks the ball's trajectory to the hoop and then shifts to show the players.

Two basketball players and a basketball are moving: one player dribbling and shooting the ball, the other player moving to defend. The ball is also moving through the air and through the hoop.

The background (gym wall and floor) is static and shows no fluid motion (fire, water, smoke, wind).


RAW CAPTION: Got it, let's tackle this. The video is about teaching the D major chord on guitar. First, I need to describe the sequence chronologically. The video starts with a split screen: left shows a hand strumming, right shows a fretboard with a finger on the 2nd fret of the G string. Then the hand strums, and the fretting hand adjusts. Wait, the frames show the left side (strumming hand) moving, right side (fretting hand) pressing down. The chord diagram at the bottom shows fingers on specific frets.

So the main subjects are the hands. Left hand: strumming motion, right hand: fretting. The left hand strums the strings, then the right hand positions fingers. Let's outline the chronology.

First frame: left side shows a hand strumming (maybe starting to strum), right side shows a finger on the 2nd fret. Then the next frames: the strumming hand continues, the fretting hand adjusts (maybe the index finger is on 2nd fret, middle on 3rd? Wait, the chord diagram has 3, 2, 1 on the strings. Wait, the chord diagram is for D major: on the 2nd fret for the low E string (but maybe the diagram is showing the positions: 3rd fret on B string, 2nd on G, 1st on D? Wait, the diagram shows the neck with dots: first fret (1) on D string? Wait, the chord diagram at the bottom: the strings are labeled with numbers (3, 2, 1) below. Maybe the 3 is on the B string, 2 on G, 1 on D? Wait, maybe it's a standard D major chord shape: fingers on 2nd fret of G string (3rd fret of B?), but the diagram shows three dots: one on the 3rd fret of the second string from the bottom (B string), 2nd fret of third string (G string), and 1st fret of fourth string (D string). Hmm, but the video is a split screen showing the strumming hand on the left and the fretting hand on the right.

In the video, the left side shows a hand strumming the guitar (strumming motion, fingers moving across the strings). The right side shows a hand pressing down on the 2nd fret (probably on the G string). Then the strumming continues, and the fretting hand is shown. Wait, the frames go from initial position to strumming. So the sequence is:

- First frame: left side has a hand strumming (fingers moving), right side has a hand pressing a note on the 2nd fret.
- Then, the strumming hand continues, the fretting hand adjusts (maybe showing the full chord position).

So the motion is the strumming hand moving rhythmically to play the strings, while the fretting hand positions fingers on the fretboard to form the D major chord. The camera perspective is split screen: left shows the body of the guitar and strumming hand, right shows the fretboard and fretting hand. Background is dark except the guitar parts. Need to mention the hands' movements, appearance (color? But not important, just hand), size (hands are normal size), orientation (left hand strumming, right hand fretting).

Following the rules: focus on motion chronologically. First, the strumming hand moves to play the strings (left side), then the fretting hand positions fingers on the fretboard (right side). The chord diagram at the bottom is part of the visual but we don't mention text. So the caption should describe the actions of the hands.

Let's structure:

A hand strums the guitar strings on the left side of the split screen, while another hand positions fingers on the guitar fretboard to form the chord on the right side. The strumming hand moves rhythmically across the strings, and the fretting hand adjusts to place fingers on specific frets (noting the chord diagram shows finger positions). Both hands are visible against a dark background, with the camera maintaining a split-screen perspective showing both the strumming and fretting actions without movement.

Wait, need to be concise. Let's check the rules again: exclude text recognition, so don't mention the chord name. Focus on motion, appearance (color? probably not, but maybe "a hand" without color). Spatial relationships: left side strumming, right side fretting. Camera is split screen, no movement (since it's a static split screen with different angles).

So final caption:

A left hand strums the guitar strings rhythmically while a right hand positions fingers on the fretboard to form a chord, visible in a split-screen

A hand is moving discretely: strumming (right side) and fretting (left side) the guitar strings.

Background elements (guitar illustration, fingerboard diagram) remain static with no shifting or fluid motion. No fire, water, smoke, or wind present.


A person wearing a teal shirt and dark apron with light straps rolls a wooden rolling pin over a folded white cloth on a wooden countertop. They lift the cloth to expose a round plate beneath, revealing its surface. The kitchen background includes shelves with glassware and an oven. The camera remains stationary, capturing the action from a fixed eye-level angle.

The person manipulates dough and a bowl, moving their hands and objects via explicit physical actions (rolling, placing).

Background elements (walls, kitchen appliances) are static; no fluid/environmental motion (fire, water, smoke, wind) is present.


A metallic angle grinder with a spinning disc makes contact with a dark metal object featuring an orange stripe, generating sparks as it grinds along the object's surface. The grinder moves steadily along the metal, producing continuous sparks against the concrete floor background. The metal object remains stationary during the grinding process. The camera maintains a close-up, fixed perspective focused on the grinding action.

The shoe and electric polishing machine are moving in controlled, discrete motions relative to each other (circular/linear polishing action), with the hand holding the machine also exhibiting motion.

The background (concrete floor) remains static with no shifting or environmental motion; no fire, water, smoke, or wind is present.


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 main subject's actions, appearance, spatial relationships, camera perspective, and minimal background details.

Looking at the video frames provided, the main subject is a person wearing a brown and white striped shirt with a patterned scarf. They're holding a yellow apple and peeling it. The person is seated at a table with some items like a blue folder and papers visible.

Starting with the first frame: the person is holding the apple, peeling it with their hands. The camera seems to be close-up, possibly handheld, as there's a slight shake. The background is indoors, maybe a café or home setting with tables and chairs.

Next, I need to sequence the actions. The person starts peeling the apple, then continues. Their hands are actively moving, with the apple being peeled in sections. The apple is yellow, medium-sized, and they're holding it with both hands. The table is in front of them, and there's a blue folder on the table.

I should mention the appearance briefly: the person's shirt has stripes, the scarf is patterned. The apple is yellow. Spatially, the apple is in their hands, the table is in front. Background is minimal, maybe just the table and some items.

Camera perspective: close-up, slightly shaky, maybe handheld. Moving a bit but staying focused on the person's hands.

Need to avoid text recognition, named characters, etc. So no mentioning specific details like the brand of the shirt or exact background items. Just the essentials.

Putting it all together: The person, wearing a brown and white striped shirt and patterned scarf, is seated at a table. They hold a yellow apple in both hands, peeling it methodically. The apple is peeled in sections, with the person's hands moving steadily. The table in front has a blue folder and papers. The camera maintains a close-up, slightly shaky perspective on the hands and apple, with minimal background detail visible.

Wait, the user said to exclude background details unless essential. So maybe the table and blue folder are not essential. The background might just be a room with tables and chairs, but maybe it's better to omit unless necessary. Let me check the rules again: "Mention spatial relationships if relevant (e.g., in front of, to the left)." The table is in front, so maybe that's relevant.

Also, the video shows the person peeling the apple, so the chronological order is the person holding the apple, peeling it. The camera is close-up, moving slightly but focused on the hands and apple.

Check the output format: must be in <caption_output> tags. Concise paragraph. Let me structure it:

A person wearing a brown and white striped shirt and patterned scarf sits at a table, holding a yellow apple in both hands. They peel the apple methodically, rotating it to remove the skin in sections. The table surface in front holds a blue folder and papers. The camera maintains a close-up, slightly shaky perspective focused on the hands and apple, with minimal background detail visible.

Wait, the rule says to exclude background unless essential. The blue folder might be essential because it's on the table. But the user says "keep background descriptions minimal unless essential for understanding motion." If the motion is peeling the apple, maybe the background isn't essential. The table is in front, but maybe it's okay to mention the table as a surface where the person is sitting. But perhaps the main focus is on the person and the apple.

Let me check the example again. The user provided the video clips, and the first frame shows the person with the apple. The background is a room with tables and chairs, but maybe it's too vague. The caption should focus on the main action.

Maybe the correct approach is to focus on the main subject's actions without much background. So:

A person in a brown and white striped shirt and patterned scarf holds a yellow apple with both hands. They peel the apple methodically, rotating it to remove the skin in sections. The camera remains close-up and slightly shaky, focusing on the hands and apple throughout the sequence.

That's more concise. Omit the table and background details unless necessary. The background might not be essential here. The key is the person peeling the apple, their appearance, and the camera perspective.

Wait, the user's example output includes "seated at a table" but maybe that's okay. Let me check the rules again. Rule c: mention spatial relationships if relevant. The person is seated at a table, so if the table is part of the scene, it's relevant. But the background details should be minimal. The table is the only thing mentioned in the background. The blue folder and papers might be part of the background but

A person's hands are actively manipulating a fruit (e.g., peeling), with distinct motion from hand movements and interactions with the fruit.

Background elements (tables, chairs) are stationary and show no uniform shifting; no fluid/environmental motion (fire, water, smoke, wind) is present.


A dark, rounded object rests on a light, textured surface. A light-skinned hand enters the frame from below, grasps the object, lifts it upward, and then withdraws, clearing the object from view. The camera remains static in a close-up perspective throughout.

A bat-shaped object is moving, flapping its wings and changing position across the frame. It is the only discrete object with clear motion.

The background appears to be a static pattern (wall with speckles) without uniform shifting. No environmental fluids (fire, water, smoke, wind) are present. The motion is dominated by a solid object.


A hand with light skin, holding a light-colored pencil, moves across a spiral-bound sketchbook, adding detailed lines and shading to a drawing of a tall, rectangular structure with horizontal elements. The hand shifts positions, working on different sections of the sketch while the sketchbook rests on a soft, muted surface. The camera maintains a close-up perspective, capturing the hand’s motion and the evolving sketch without significant movement or shift in focus.

A hand holding a pencil is actively drawing on the notebook page, moving to add details to the sketch with controlled, discrete motions.

The background (notebook page and fabric surface) remains static with no shifting, fluid motion, or environmental effects; no fire, water, smoke, or wind present.


A person in a white sleeve approaches a gray industrial machine, moving their hand to open a compartment panel. The hand then inserts into the revealed internal opening, with the camera maintaining a close-up focus on the machine and the hand’s interaction. The perspective shifts slightly to capture the hand's motion within the machine's opening.

A person's hand moves to open a compartment of a machine and points inside.

The background elements (machine and walls) are static with no fluid or environmental motion (fire, water, wind).


A person in a blue shirt and red shorts stands under a balcony overhang, adjusting a white window. They move slightly to the right, stepping back from the window. The camera pans right, revealing a blue sky and a tree in the background.

A person in a blue shirt is moving (turning head, shifting body, and stepping away from the window). The person is holding a white object (possibly a towel) that moves with the person.

The background includes a static building structure and a sky with subtle cloud movement. The trees at the edge of the frame show slight swaying, but this is not dominant.


A person in a green dress uses a wooden rolling pin to flatten a folded light-colored dough on a table; the hands maneuver the rolling pin horizontally across the dough, gradually spreading it. The camera maintains a close-up top-down perspective focused on the hands and dough.

A person's hands and a rolling pin interact with dough, moving the dough through rolling motion due to applied physical force.

Background elements (wall, table surface) show no uniform shifting or fluid motion; no fire, water, smoke, or wind detected.


A person in a gray shirt and red cap stands facing another person in a dark shirt near shelves; the second person reaches toward the shelves. The first person turns and walks away, moving through a doorway, followed by the second person. The camera follows the movement with a slight shake.

A person (in red cap) is punching a black and red punching bag, causing it to move. The person then moves around the bag and walks away, returning later. The motion is due to explicit physical forces (punching).

No shifting background elements (walls, shelves remain stable). No fluid or environmental motion (fire, water, smoke, wind) observed.


A boy wearing a blue shirt and orange shorts runs from the left toward a large tree, grasps its trunk, and begins climbing upward. The camera remains stationary at a low angle, with a wooden fence and house visible in the background.

Briefly describe what discrete, solid objects are moving.

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


A person wearing a teal shirt and dark pants sits on a metal chair on a porch, manipulating a wooden object with their hands while seated to the left of a railing; the camera shifts slightly, maintaining a view of the grassy background and a small tree beyond the railing.

A person seated on a chair exhibits minor hand movements while holding an object (e.g., a cup), consistent with discrete solid object motion.

The background elements (railing, grass, trees) show no uniform shifting or fluid motion. There is no fire, water, or significant smoke. Tree sway appears minimal and is not dominant.


A shirtless man in blue shorts sits on a bed, focused on manipulating a small object in his hands. The bed features a wooden headboard, scattered items including a red bag, and a partially visible person lying down in the background. The camera remains stationary, capturing the man from a slightly low angle with minimal background details.

A shirtless man is seated on the bed, actively manipulating a small object (likely a phone) with his hands. The other person in the background remains motionless on the bed.

The background elements (wooden bed frame, wall) remain stationary throughout. No fluid motion (water, fire, smoke) or wind-induced environmental effects are present.


A shirtless person wearing dark blue shorts lies prone on a table as another individual’s hands massage their back. The camera starts with a close-up top-down view, then gradually pulls back to reveal more of the room, including the floor and wall. The massaging motion continues throughout the sequence.

A person lying face-down on a surface, with subtle movements (e.g., shifting position, slight adjustments) indicating physical motion. The person's body is the primary discrete object in motion.

The background consists of static elements (white wall, green structure, floor) with no uniform shifting or fluid motion (fire, water, smoke, wind) observed. Background remains consistent across frames.


A person in a pink apron shapes dough into round forms on a floured kitchen countertop, using hands to fold and seal the dough. The countertop holds rolled dough pieces, a wooden rolling pin, and scattered flour. The person then places the formed dough onto a baking sheet lined with flour, which is filled with multiple shaped dough items. The camera shifts to a top-down view of the baking sheet, then pans to show the tray with neatly arranged dough pieces.

Discrete solid objects (dough pieces) are being manipulated by hands: pinching, shaping, and placing onto a tray.

No shifting backgrounds or fluid/environmental motion observed; kitchen elements (countertop, rolling pin, flour) remain static throughout the clip.


A person (wearing a hat, red vest, and red pants) is sitting on the ground and moving their hands and arms (adjusting hat, pointing/gesturing).

The background consists of a rocky wall and calm water. There is no significant fluid or gaseous motion (e.g., waves, wind) to dominate the scene. The water is static.


A person in a yellow tank top and blue jeans uses tongs to rotate a glowing orange glass orb over a metal stand, then shifts to a wider shot revealing them seated at a workbench, shaping the glass with a rod while a furnace glows in the background. The camera transitions from a close-up of hands manipulating the orb to a broader perspective of the workspace.

A person in a yellow top manipulates a molten glass orb using tools (e.g., blowpipe, shaping rod). The glass orb and tools exhibit discrete physical motion as the person rotates, shapes, and handles the molten glass.

The background includes a stationary furnace with visible flames and industrial metal structures. The flames represent ambient environmental motion, but they are not the dominant focus of the video.


RAW CAPTION: Okay, let's tackle this video captioning task. The user provided a video clip with several frames, and I need to create a concise chronological paragraph following their specific rules.

First, I should look at the video frames given. The first frame shows a TV screen with a group of people dancing. The text on the screen says "We have to touch the skies." There are people in red and white outfits, moving energetically. The next frame has a bright blue light effect, maybe a spotlight or some visual effect. Then there's another frame with more people, the text changes to "And hum our tune." Then it shifts to a dark scene with the text "The heart says, be like the cloud." Finally, the last frame is a dark background with people still moving, and the text "And drown yourself."

Wait, but according to the rules, I need to exclude text recognition. So I shouldn't mention any of the subtitles. The user specified not to include named characters, stylistic analysis, or text. So I have to focus on the motion and behavior of the main subjects.

Looking at the main elements: people dancing, changing scenes with bright lights, maybe a group of people in red and white. The video seems to transition between different scenes with lighting effects. The camera perspective is probably from someone recording the TV, so it's a slight shake as the camera moves around the TV.

Let me check the rules again. The caption should be chronological, describe motion and behavior, appearance and number (color, size, orientation), spatial relationships if relevant. Conclude with camera perspective and movement.

First frame: people dancing on stage. Maybe a group, some in red, some in white. They're moving energetically. Then a bright blue light effect, maybe a spotlight. Next, another scene with people, then a dark scene. The camera seems to be handheld, moving slightly as it records the TV.

Wait, the video is of a TV screen, so the camera is capturing the TV from a distance, possibly a bit shaky. The TV itself shows different scenes, but the caption should describe what's on the TV, not the camera moving. Wait, no—the rules say "conclude with the camera perspective and movement". So the main subject is the video content, but the final part should mention how the camera is positioned.

Wait, the user says: "conclude with the camera perspective and movement (e.g., top-down, pan left, slight shake)."

So, the main part is describing the video content chronologically, then the camera perspective.

Let me structure this.

Chronologically:

1. The video starts with a group of people dancing on stage, wearing red and white outfits, moving energetically. They are in a dimly lit setting with blue lighting. Then the scene transitions to a bright blue light effect, possibly a spotlight or visual effect. Next, the scene changes to a darker setting with people still moving. Then it shifts to another scene with people dancing, and finally a darker scene where the people are less visible.

Wait, but need to check the exact frames. The first frame has "We have to touch the skies." text, then next frame shows a person in a white shirt (maybe) with blue light, then "The heart says..." etc. But according to the rules, exclude text, so I shouldn't mention the text. So focus on the visuals.

The main subjects are people dancing in groups. The first scene has people in red and white, moving. Then a bright light effect. Then another scene with people, then a dark scene.

Now, appearance: number of people. The first frame shows a group, maybe around 5-6 people. In red and white. Then in the next frame, a person in white shirt, maybe others around. Then a blue light burst. Then the scene changes to darker, with people still dancing. The last frame is dark with people moving.

Spatial relationships: The people are on stage, maybe in front of a backdrop. The camera is filming the TV, so the perspective is from a distance, possibly handheld, with slight movement.

Wait, the video is recorded from a room where the TV is mounted on the wall. The camera filming the TV is probably a bit shaky, moving slightly.

So, the caption should describe the sequence on the TV: start with dancing people (red and white), then a bright blue light, then another scene, etc., then the camera is handheld with slight shake.

Let me try drafting:

The video opens with a group of people dancing energetically on stage, wearing red and white outfits, moving in sync. The scene transitions to a burst of bright blue light, followed by a darker setting with individuals continuing to dance. The figures shift positions, with some moving forward while others remain in the background. The camera captures the television screen from a distance, exhibiting slight handheld movement and a

Discrete solid objects (people) are moving on stage, exhibiting gestures and locomotion consistent with singing and performing.

The background elements on the TV screen show stage lighting and structural elements, which are static within the TV content. No dominant fluid/environmental motion (fire, water, smoke) is observed as the primary 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 that describes the video, following specific rules.

Looking at the provided frames, the video is a bit blurry, so I have to focus on the main actions. The main subjects are two people, one in a red shirt and another in a patterned shirt. The first frame shows them sitting close, the second frame has the person in red leaning over, maybe using a phone. Then, in the third frame, the person in red is still engaged with the phone, and another hand enters the frame. By the fourth frame, the hand is pointing towards the phone. The fifth frame shows the person in red holding the phone, and the other person's hand is still there. The camera moves a bit, possibly handheld, giving a shaky perspective.

Wait, the rules say to mention motion and behavior in chronological order. So I need to describe what happens step by step. The two people are interacting with a phone. The person in red is using the phone, maybe taking a photo. Another person's hand reaches in, possibly to adjust or point at the phone. Then the person in red continues to hold the phone, maybe showing something.

Appearance: red shirt, patterned shirt. Number: two people. Spatial relationships: one in red is sitting, the other in patterned is next to them. Camera movement: shaky, maybe handheld.

Need to keep background minimal. The background is dark, maybe indoors with some people around, but not essential. Avoid text recognition, so no mention of what's on the phone.

Let me check the rules again. Focus on motion and behavior, chronological. So start with the first frame: two people sitting close. Then person in red leans in, uses phone. Next, another hand reaches towards the phone. Then the person in red continues holding the phone as the other hand points. Camera moves a bit, possibly handheld.

Make sure to mention the number of people (two), their shirts, the action of holding the phone, the hand pointing. Conclude with camera perspective as shaky handheld.

Wait, the output should be in a paragraph. Let me structure it step by step:

In the video, two people interact closely. A person in a red shirt holds a phone, while another individual in a patterned shirt sits beside them. The person in red leans forward, using the phone, then another hand reaches in from the right to touch the phone screen. The person in red continues holding the phone as the second individual's hand points toward it. The camera remains close, handheld, with slight movement.

Check for chronological order: start with sitting, then leaning, hand reaching, then pointing. Mention the shirts and spatial relationships. Camera is handheld, shaky. Background is minimal. Exclude text, names. Should be concise.

Wait, the first frame says [0.0] so start from there. Maybe "Initially, two people sit closely together..." then describe each action in order. Make sure the description flows chronologically.

Let me draft:

The video shows two individuals seated closely. A person wearing a red shirt holds a phone, while another person in a patterned shirt sits beside them. The individual in red leans forward to use the phone, then another hand enters from the right to point at or adjust the device. The person in red continues to hold the phone, maintaining focus on the screen as the second individual's hand gestures toward it. The camera remains at a close angle, capturing slight handheld movements and shifting perspectives between the subjects.

Check if this meets all rules. Number of people: two. Appearance: red shirt, patterned. Motion: leaning, pointing, holding. Spatial: seated beside, hand from right. Background minimal. Camera handheld, slight movement. Yes. But need to be concise. Maybe shorten.

"Two people sit closely: one in a red shirt holds a phone, the other in a patterned shirt sits beside them. The person in red leans forward to use the phone, then a second hand enters from the right to point toward the screen. The individual in red continues holding the phone while the other gestures toward it. The camera remains handheld, capturing slight movements and shifting perspectives between the subjects."

Check rules. Mentioned motion, chronological, appearance, spatial. Camera perspective. Background minimal. Looks good. Maybe "another hand" can be specified as "a hand from the right." But the rules say to mention spatial relationships if relevant, so "from the right" is okay. Also, the hand gestures "toward the screen" as the subject. Yes.

I think that works.

Two individuals interacting with a small object (toy or game piece). Hands and object move as they pass or manipulate it.

No fire, water, smoke, or wind evident. Background is blurry and not clearly defined, but no fluid/environmental motion is present.


A person holds a pastry topped with chocolate glaze and multicolored round candies, moving it toward their mouth. They then present a second pastry covered in crumbly cinnamon toast pieces and white icing, holding it up in front of them. The camera maintains a close, slightly low-angle perspective with minimal movement.

A person holds and manipulates two distinct solid objects: a Reese's Pieces-topped pastry and a cinnamon toast crunch item. Motion involves hand movements, rotation of the pastries, and bringing them closer to the camera.

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


RAW CAPTION: Okay, let's tackle this captioning task. First, I need to understand the video sequence based on the provided frames. The video starts with a black screen, then transitions to an underwater scene with the ZOGGS logo. The logo is blue with yellow text, and the text "Breaststroke Kicking" appears. Then it changes to "Swim 4 Fitness" with the ZOGGS logo integrated. Finally, there's a swimmer in a pool.

The user wants a concise, chronological paragraph focusing on motion and behavior. Rules say to exclude text recognition, so I shouldn't mention the logos or the text like "Breaststroke Kicking." Need to stick to the actions of the subjects. The main subject here is the swimmer. Let's break it down.

First frame: black screen. Then underwater with ZOGGS logo. Then the logo changes to Swim 4 Fitness, but maybe the swimmer appears in the next frame. Wait, the fourth frame shows the swimmer in the pool. So chronological order is: black screen, underwater logo, then swimmer.

Wait, the video starts with [0.0] black, then [1.4] underwater with ZOGGS, [2.5] still underwater with "Breaststroke Kicking" text, [3.6] changes to "Swim 4 Fitness" logo, [4.7] shows a swimmer.

But according to the rules, I need to exclude text recognition, so the text parts are not to be mentioned. So the actual action part is from the swimmer. The swimmer is in the pool, doing breaststroke kicking. The description should focus on their motion.

The swimmer is wearing a purple cap and a dark swimsuit. They're performing breaststroke kicking, so their legs are moving in a frog kick. The camera perspective: probably underwater or above water? The frames show underwater initially, then the swimmer appears in the pool. Wait, the last frame says "a swimmer in a pool," so the camera is probably capturing them from above or side.

Wait, the video starts underwater with the logo, then transitions to the swimmer. The description should list the sequence. But since text is excluded, maybe the swimmer is the main action. Let's outline:

Starts with black screen. Then underwater scene with the logo (but text excluded), then the swimmer appears in the pool. The swimmer is doing breaststroke, legs kicking. The camera is likely following the swimmer's movement. But the user says "background descriptions minimal unless essential for understanding motion."

So the main points: the swimmer is in a pool, wearing a purple cap and dark swimsuit, performing breaststroke kicking motion, legs moving in a frog kick. Camera perspective might be above water, following the swimmer.

Wait, the fourth frame shows the swimmer in the pool, so perhaps the transition from underwater to pool scene. But maybe the camera is underwater initially, then moves to above water to show the swimmer. However, the rules say to focus on motion and behavior, so the key is the swimmer's action.

Let me try to structure it step by step:

- First frame: black screen.
- Then underwater with logo (but text excluded, so ignore that).
- Next, swimmer appears in pool, doing breaststroke. The swimmer's legs are kicking in a breaststroke motion.
- The swimmer's appearance: purple cap, dark swimsuit.
- Camera perspective: likely above water, possibly following the swimmer's movement.

But the problem is to avoid mentioning the logo and text. So the caption should mention the swimmer's action without referencing the logos or text. So the sequence is:

The video begins with a black screen, then transitions to an underwater scene. A swimmer wearing a purple swim cap and dark swimsuit is seen performing breaststroke kicking in a pool. The swimmer's legs execute a frog-like motion, pushing water backward with each kick. The camera maintains a side view, following the swimmer's movement through the water.

Wait, but the initial frames are underwater with logos, but the user says to exclude text and logos. So the caption should start with the swimmer's action. Maybe the first part (black screen) is part of the video but since it's the start, perhaps the caption can start from the main action.

But the user says "chronological order," so need to mention the sequence of events. However, the main content is the swimmer. Let's see the example output format.

Wait, the example in the problem statement says: the video starts with black, then underwater with ZOGGS, then swimmer. But according to the rules, exclude text, so we should not mention the logos.

So the caption would start with the black screen, then underwater (but maybe not mention the logo),

A swimmer (discrete, solid object) is moving through the water due to breaststroke kicking locomotion, visible from the kicking motion and the body's position.

The background (pool walls and floor) is static. Water movement is a consequence of the swimmer's motion and not dominant, so not classified as ambient_environmental.


A hand uses a white cloth to wipe a light-colored round plate in circular motions, moving the cloth across the plate’s surface; a light-colored container remains stationary to the right. The camera maintains a top-down perspective with minimal movement.

The hand and foot are moving. The hand is moving the foot in a controlled manner (washing action) within a basin. The water is being agitated but is not the primary moving object.

The background is static and non-shifted. There is no dominant fluid or environmental motion (e.g., water, fire, wind). The water in the basin is contained and not flowing freely, so it does not qualify as ambient.


A person wearing a black and white striped sweater with a pink flower stands in front of a wooden and tiled wall. They hold a phone to their ear with their right hand, making minor adjustments to the earphones. The camera remains static throughout.

The person (wearing striped shirt and earphones) is moving their mouth and hand (holding an object) due to talking or chewing, representing discrete solid object motion.

No shifting background; no fire, water, smoke, or wind. Background elements (wooden panel and white wall) are static throughout the frames, showing no uniform motion.


A person in a beige shirt stands indoors. The scene cuts to two individuals at a table: one in a red shirt holds a ball, the other in a dark blue shirt with the number 36 holds a cup. The person in red gestures toward the blue cups arranged in a triangular formation on the table. The camera shifts between these scenes, focusing on the individuals' actions and the cup setup, with minimal background details.

The discrete objects in motion include: (1) the two players (moving their arms to throw and catch) and (2) the ball (thrown and landing in a cup, showing clear collision physics).

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


The video displays a split-screen format with two subjects. On the left, a person lies motionless in a dimly lit space, occasionally shifting position slightly. On the right, a person in a pink top and white head wrap stands in a room with a bed and dresser, gesturing with their hands while speaking. The camera maintains a static split-screen perspective throughout, with no significant movement or change in angle.

The person in the right panel (Kaya's Dance) is moving, displaying gestures and head movements. The person in the left panel (American Betsy) is static throughout the provided frames.

No shifting background or fluid/environmental motion observed in either panel. The background in the right panel (room with furniture) remains stationary, and the left panel is static.


Three people, two in dark clothing and one in light, push a beige car from the front across a grassy field. They lean forward, applying force to move the vehicle forward, with their bodies positioned close to the car's hood and sides. The camera maintains a static ground-level perspective throughout, capturing the motion without movement or change in angle.

Two people pushing a stalled car through mud; the car moves forward incrementally while the people apply force with their bodies. Mud displacement is a consequence of the car's motion, not primary motion.

Static background of trees and grass shows no uniform shifting or environmental motion (e.g., wind, smoke). Mud displacement is secondary to the car's movement and not dominant.


Two hands adjust a small white rectangular frame on an orange polka dot paper sheet placed on a pink cutting mat. The hands reposition the frame multiple times, then lift it off the paper. Next, they pick up a pink spray bottle and spray the mat surface. Finally, the hands place a sheet with blue and yellow shapes onto the mat. The camera remains in a top-down perspective throughout, with minimal movement.

Hands are actively manipulating solid objects (paper, scissors, adhesive tools) through deliberate physical actions (cutting, placing, adjusting), indicating discrete object motion due to manual force application.

The background consists of a static pink surface with various craft items (paper, tools, etc.) that do not shift or exhibit fluid/environmental motion (e.g., no fire, water, smoke, or wind).


Two individuals in black-and-white patterned shirts sit at a table, their hands manipulating food items; the person in the foreground passes a plate to the right while the other assists. The camera pans left, revealing a third person in matching attire standing behind, all engaged with the table. The camera remains close, maintaining focus on the table interactions with minimal background detail.

Discrete solid objects (people) exhibit motion: hands moving to manipulate food/utensils at the table, indicating physical actions.

Static background elements (walls, table, chalkboard) show no uniform shifting; no fire, water, or wind effects present.


RAW CAPTION: Got it, let's tackle this. First, the video shows two people. One is sitting on a wooden bench, wearing a purple jacket and a green headscarf. The other is standing, wearing a black top, jeans, and a wide-brimmed hat. They're interacting with some ropes or strings. The sitting person is holding the rope, and the standing one is adjusting or tying it. Let's note the sequence: the standing person gestures, then the sitting person moves their hands. The background has trees and another bench, but we keep it minimal. Camera perspective: it's a steady shot, maybe slight movement? Wait, the rules say describe camera perspective and movement. The video starts with them, and maybe the camera is stationary but slightly shifting? Let's check the frames. The first frame to the fifth, the camera might be steady with a slight pan? Wait, no, the problem says "conclude with camera perspective and movement". Let's see: the video is outdoors, two people. Main subjects: two people. Chronology: the standing person is adjusting the rope, the seated person moves their hands, possibly passing or holding the rope. Spatial: standing person is to the right of the seated person. Background: trees, grass, another bench. Camera: probably static with maybe a slight shake? Wait, the output needs to be concise. Let's structure it.

Start with the main actions in order. The person standing (black top, hat) interacts with the seated person (purple, green headscarf) over a rope. The seated person moves their hands as the standing person adjusts. Then, camera perspective: since it's a video, likely a medium shot, maybe slight movement. Wait, the rules say "conclude with camera perspective and movement". So the caption should end with that. Let's draft:

Two people interact outdoors: a seated individual in a purple jacket and green headscarf holds a rope while a standing person in a black top, jeans, and wide-brimmed hat adjusts it. The standing person moves their hands to manipulate the rope, then the seated person shifts their grip. The background includes trees and a wooden bench. The camera remains stationary with minimal movement.

Wait, but need to be concise. Let's check the rules: chronological paragraph. So step by step.

First, the seated person (purple, green headscarf) is on a bench. Standing person (black top, hat, jeans) approaches. They handle a rope: standing person manipulates the rope, seated person moves their hands to interact. Then, seated person adjusts their position slightly. Camera perspective: top-down? No, it's a medium shot. Wait, the video is in a yard, so camera is eye-level. Movement: maybe slight shake, but the description should be brief.

Let me rephrase:

A seated person wearing a purple jacket and green headscarf sits on a wooden bench, while a standing person in a black top, jeans, and wide-brimmed hat handles a rope. The standing person adjusts the rope, prompting the seated individual to move their hands to assist. The background features trees and another wooden bench. The camera maintains a steady, eye-level perspective with minimal movement.

Check if it's chronological. Yes: seated on bench, standing handles rope, then seated moves hands. Spatial: standing person is in front of the seated person (since they're interacting). Wait, "standing person is to the right of seated person" but maybe not necessary. The rules say "mention spatial relationships if relevant". So if they're interacting, maybe the standing person is facing the seated one.

Let me check the frames: in the first frame, standing person is to the right of seated. So spatial: standing person stands to the right of the seated individual.

So revised:

A person in a purple jacket and green headscarf sits on a wooden bench, while a standing individual in a black top, jeans, and wide-brimmed hat manipulates a rope. The standing person gestures with the rope, then the seated person moves their hands to interact. The background includes trees and a wooden bench. The camera remains stationary with slight movement.

Wait, "manipulates" – maybe "adjusts". Let's make sure it's chronological: standing person starts by adjusting the rope, then seated person responds by moving hands. Yes.

Let's check the rules again: concise, chronological paragraph. Focus on motion and behavior. So:

Two people interact: one seated on a wooden bench (purple jacket, green headscarf) and one standing (black top, jeans, wide-brimmed hat). The standing person adjusts a rope held by the seated individual, who then shifts their hands to assist. Background has trees and another bench. Camera is steady with minimal movement.

That's concise. Let's see if it's under the rules. Exclude text, named characters, stylistic

Two individuals (one seated, one standing) exhibit discrete hand movements and body shifts during interaction, indicating intentional motion of solid objects.

Background elements (trees, wooden structure, white chair) are stationary with no uniform shifting or fluid environmental motion (fire, water, smoke, wind) observed.


A white multifunction printer outputs printed documents, one featuring a circular graphic and the number "10"; a hand reaches from the right to remove a printed sheet from the output tray, leaving it empty. The scene shifts to a close-up of a white printer’s surface showcasing a WiFi symbol. The camera maintains a static perspective initially, then transitions to close-up shots of printer components.

A hand (discrete solid object) moves to extract printed sheets from the printer tray. The hand's motion is deliberate and physically driven by the person's arm action, with no environmental or camera-induced influence.

The background is a static white surface with no shifting or fluid motion (e.g., no fire, water, smoke, or wind). The primary background elements (printer, tray, and surface) remain uniformly stationary throughout the video.


Two individuals sit across a wooden table, facing each other; the person on the left wears a light-colored long-sleeve top and has dark hair, while the person on the right wears a light shirt. They grip hands together, then gradually release and move their hands apart. The camera remains static with minor handheld shake, capturing the interaction from a fixed position.

Two people are engaged in arm wrestling at a table. Their arms, hands, and upper bodies exhibit discrete motion due to physical force exertion. The motion is localized to their limbs and is easily trackable with bounding boxes.

The background shows a stable indoor room with furniture (tables, chairs, green bucket) that remains stationary throughout. No fluid motion (fire, water, smoke) or wind effects are present. Background elements do not shift uniformly, indicating no ambient environmental dominance.


A person in a gray shirt and dark cap holds a yellow recurve bow on a grassy field, drawing the bowstring, aiming at a distant goalpost, releasing the arrow, and lowering the bow. The background features a clear sky and trees with the goalpost positioned far ahead. The camera remains stationary with slight handheld shake.

A person holds a bow and arrow, drawing the bowstring and releasing the arrow; the person's limbs and the bow exhibit discrete motion from their own physical actions.

Grassy field, trees, and soccer goal remain static with no shifting or fluid motion (fire, water, wind not present).


A person in a red shirt stands at the far end of a wooden shuffleboard table, pushing two dark pucks forward. The pucks slide rapidly toward the camera, with one overtaking the other; the leading puck exits the frame to the right while the trailing puck continues sliding. The camera remains stationary at the near end of the table, angled low to capture the motion against a brick wall visible on the left side. Background details are minimal, emphasizing the pucks' movement along the table's surface.

Discrete solid objects (shuffleboard balls) are moving along the wooden table due to physical forces (sliding motion), with clear tracking of their trajectories against the static background.

No shifting background elements or fluid/environmental motion observed; the brick wall and wooden surface remain static throughout the frames, indicating no ambient environmental effects.


A person's hands hold and shuffle Monopoly cards above a colorful board with marked squares and a die, then place the cards onto specific spaces on the board. The camera maintains a close-up view, shifting slightly to capture the placement of cards and the board's layout.

Hands manipulate solid, distinct objects (playing cards) through physical actions like shuffling, placing, and moving cards on a table. Cards are discrete, solid objects undergoing explicit locomotion via human interaction.

The background elements (table surface, card layout) show no uniform shifting or fluid motion; no fire, water, smoke, or wind is visible. Background remains stable with minor static elements.


Two dark silhouettes stand close together against a bright blue background; one gradually moves away while the other shifts position, maintaining proximity. The camera remains static with minimal movement.

Two distinct silhouettes (likely people) moving due to their own locomotion (one falls and moves away, the other remains but changes position).

The background is a solid blue screen with no shifting or environmental motion (fire, water, wind).


A woman in a white dress walks past a person in a bright green outfit with a multicolored hat, who then gestures toward a man in a white shirt and striped tie; the man steps back as the green-clad individual continues gesturing, with other onlookers standing nearby. The camera follows the interaction with slight movement.

People (e.g., individual in green robe, woman in white top, man in white shirt/tie) moving through space via locomotion; no collisions or fluid interactions.

No shifting background elements (walls, bars remain static); no fire, water, smoke, or wind motion observed.


A woman in a white coat and face mask leans over a patient lying under a blue sheet, adjusting a white cylindrical device positioned over the patient's face. She maintains contact with the device, making slight movements while the patient remains still. The background features a desk with bottles and a lamp, with the camera capturing the scene from a static angle without movement.

The standing medical professional (doctor) exhibits minor hand/upper-body movements while attending to the patient lying on the bed. Both the doctor and patient are solid, discrete objects with motion due to intentional physical actions.

The background elements (walls, furniture, medical equipment) show no uniform shifting or fluid motion. No fire, water, smoke, or wind-driven motion is present.


...<caption_output>. Let me check the exact example.  Wait, the user provided an example in the rules. Let me check the problem statement again.  Wait, the user says: "Output Format: <caption_output>YOUR FINAL CAPTION HERE

A human foot enters and exits the frame, indicating movement due to locomotion (walking).

No shifting background elements (dirt, hose, foliage) detected; no fire, water, smoke, or wind motion observed.


A pair of hands manipulates a small, multi-colored Rubik's Cube, initially showing green, white, and orange faces. The hands rotate the cube, revealing new faces in sequence (orange, blue, green), with the cube's orientation continuously changing. The background features blurred wooden cabinets. The camera maintains a close-up, steady perspective focused on the hands and cube throughout.

The cube is a solid, distinct object being rotated by hands. The motion is due to explicit physical manipulation (turning the cube).

The background (wooden shelves and monitor) is static and shows no shifting or environmental effects such as fire, water, or wind.


A person wearing a dark jacket and red pants rides a brown horse through a rocky canyon, guiding it as it steps over large boulders. The horse moves forward steadily, navigating uneven terrain between tall rock formations. The camera follows the horse’s movement, panning slightly to maintain focus on the rider and horse as they progress through the narrow passage.

A rider on horseback moves through rocky terrain; the horse and rider are discrete solid objects exhibiting locomotion driven by physical forces (riding/pacing).

The rocky terrain and wooden structure remain relatively stable across frames, indicating minimal ambient environmental motion (water flows but is not dominant). Background elements show no uniform shifting, suggesting no camera-induced motion.


RAW CAPTION: Got it, let's tackle this. First, the video starts with a person holding two yellow balls. They're in a black shirt with a colorful design. The person moves the balls around, then the screen goes dark, and a logo appears. Then it goes back to the person. Wait, the rules say to focus on motion and behavior in chronological order.

Let's break down the timestamps:

[0.0] - Person holds two yellow balls, one in each hand. Shirt is black with a graphic (but rule f says exclude text recognition, so maybe just describe the shirt as black with colorful elements? Wait, rule b says mention appearance and number. So the person is wearing a black t-shirt with a colorful design (maybe the colors are part of the design, but since it's a t-shirt, describe as black t-shirt with colorful elements).

[0.0-1.4] - The person is holding two yellow balls, moving them. Then in [1.4], the person lifts one ball up, showing it. Then [2.5] the screen goes dark, then [3.6] a logo (but rule g says exclude text recognition, so don't mention the logo's text). Then [4.7] the screen goes dark again? Wait, the video is 5 frames. Let's check:

Frame 0: person holding two yellow balls.

Frame 1: person holding one ball in right, one in left (maybe moving).

Frame 2: screen dark.

Frame 3: logo (but we can't mention the text).

Frame 4: screen dark.

Wait, the user provided 5 frames:

<0.3> - person holding two yellow balls, black shirt.

<1.4> - person holding one ball in right hand, one in left? Wait, no: "holds two yellow balls" then "holds a yellow ball in one hand, the other is below"? Wait, the description says:

[0.0] - person holding two yellow balls, black shirt.

[1.4] - person holds a yellow ball in right hand, the other is in left? Wait, the text says: "holds two yellow balls" then "holds a yellow ball in one hand, the other is below". Wait, the user's video description:

[0.0] - person holds two yellow balls.

[1.4] - person holds a yellow ball in one hand, the other is below (so one ball is held up, the other is lower).

[2.5] - screen dark.

[3.6] - logo (but exclude text).

[4.7] - screen dark.

So chronological order:

1. Person holds two yellow balls (one in each hand). Then, in the next frame, the person holds one yellow ball in the right hand, with the other ball lower (maybe in the left hand, but moved down).

Then the screen goes dark, then a logo appears (but we don't describe the logo), then the screen goes dark again.

Wait, the rules say to focus on motion and behavior of main subjects (the person and the balls). So the person's actions: initially holding two balls, then lifting one ball up (so one in hand, the other below), then the screen darkens.

Wait, the video:

- Frame 0: person holds two yellow balls (both in hands).

- Frame 1: person holds one yellow ball in the right hand, the other is lower (maybe in left hand but not raised).

- Frame 2: screen turns dark.

- Frame 3: a logo appears (but we ignore text).

- Frame 4: screen turns dark again.

So the main subjects are the person and the balls. The person is moving the balls: starting with two, then raising one.

Wait, the exact frames:

<0.3> - person holds two yellow balls, black shirt.

<1.4> - person holds a yellow ball in one hand, the other is below (so one ball is held higher, the other lower).

<2.5> - screen dark.

<3.6> - logo (but we don't describe text).

<4.7> - screen dark.

So the sequence:

Person holds two yellow balls. Then lifts one ball up (so one ball in hand, the other below). Then the screen goes dark, a logo appears, then screen goes dark again.

Now, rules:

a) Motion in chronological order.

b) Appearance and number of subjects.

c) Spatial relationships.

d) Camera perspective and movement.

e) Minimal background.

f) Exclude text, named characters, etc.

So:

Start: Person wears black t-shirt with colorful elements, holds two yellow balls (one in each hand).

Then: Person holds one yellow ball in right hand (lifted), the other ball is below

The person is manipulating two yellow balls, moving them in distinct motions (e.g., clapping, holding, rotating) which are solid objects interacting via manual force.

The background consists of a static plain wall with no shifting or fluid motion (e.g., no fire, water, or wind effects).


A man in a dark blue sweater with a circular logo and light blue shirt stands facing forward, clapping his hands together before spreading them apart in a gesturing motion. To his right, a partially visible person holds a device. The setting includes a table with a banner and a television mounted on the wall behind them. The camera remains stationary throughout.

The standing person is making hand gestures and moving their arms; the sitting person is mostly stationary.

Background elements (wall, TV, fish tank) are stationary; no fire, water, smoke, or wind observed.


A person wearing a yellow helmet, dark jacket, blue jeans, and pink shoes falls from a blue metal structure, suspended by a bungee cord. They descend gradually, maintaining a vertical orientation below the platform. The camera captures the motion from a fixed top-down perspective, showing the individual’s downward trajectory against a backdrop of a parking lot and buildings.

A person wearing a yellow helmet and safety harness is gradually moving downward along a blue structural framework, indicating deliberate locomotion.

The background elements (city streets, buildings, cars) appear static across frames; no fluid/environmental motion (fire, water, smoke) is observed.


RAW CAPTION: Got it, let's break this down. First, the video starts with silhouettes of people in a dimly lit area with a bright light in the background. There are a few people, maybe four or five, moving around. Then the scene cuts to darkness, and a person walks towards a light source, maybe a streetlight. Then it's dark again, and someone else walks towards a light. Then it cuts back to the silhouettes with the bright light, people moving. Then a person stands in the center with others around. Then darkness again, maybe a person walking away. Wait, let's go step by step.

The video has several segments:

[0.0] - Silhouettes of people (dark, so color not visible) in a foggy or smoky area with a bright light behind them. They're moving, maybe dancing or walking. Number: several people.

[1.4] - Dark scene, a person walks towards a light (streetlight maybe) in the distance.

[2.5] - Even darker, maybe the person continues, but it's very dark.

[3.6] - Back to silhouettes with bright light, people moving.

[4.7] - Brighter scene, people standing, one in the center.

[5.8] - Dark again, maybe a person walks away.

Wait, the frames are numbered 0 to 5.8? Wait, the input says [0.0] to [5.8] but the user provided 6 frames. Let's list the frames:

Frame 0: silhouettes, bright light behind, people moving.

Frame 1: dark scene, a person walking towards a light (maybe streetlight).

Frame 2: dark, similar to frame 1 but maybe different angle.

Frame 3: silhouettes again, bright light, people moving.

Frame 4: silhouettes, people standing.

Frame 5: dark scene, a person walking away from the light.

Wait, the original input shows:

<0.3 seconds> [frame 0]

<1.4> [frame 1]

<2.5> [frame 2]

<3.6> [frame 3]

<4.7> [frame 4]

<5.8> [frame 5]

So the video starts with silhouettes (frame 0), then cuts to dark (frame 1), dark (frame 2), back to silhouettes (frame 3), silhouettes standing (frame 4), dark (frame 5).

Now, the rules:

a) Chronological motion: describe the order.

b) Appearance: silhouettes (so color not visible, dark figures), number: several people (maybe 4-5), but keep concise.

c) Spatial: in frame 0, bright light behind them. In frame 1, person walks towards light. Frame 3, people moving with bright light behind.

d) Camera: pan left? Maybe, or cuts between scenes. The transitions are cuts, so camera movement is not much, but in the dark frames, maybe the camera is static.

e) Background: minimal, just the bright light in some scenes.

f) Exclude text, names, etc.

So let's structure the caption:

Start with the first frame: several silhouetted figures move in a dimly lit space with a bright light source behind them. Then, the scene cuts to darkness where a figure walks toward a distant light. Next, another dark frame shows a figure moving. It returns to silhouetted figures moving with the bright light behind them, then a group of figures stands in the light, and finally, a dark scene shows a figure walking away.

Check the chronology:

0.0: silhouettes moving, bright light behind.

1.4: dark, figure walking toward light.

2.5: dark, another figure moving (maybe same or different).

3.6: back to silhouettes with bright light.

4.7: silhouettes standing (group).

5.8: dark, figure walking away.

Now, make it concise. Mention the number of people as "several" (since can't count exactly from silhouettes). Appearance: dark silhouettes, no color visible. Motion: moving, walking, standing.

Spatial: "in front of" maybe not necessary. The bright light is behind them in some frames.

Camera perspective: cuts between scenes (so camera doesn't move continuously; it's a sequence of cuts).

So the caption:

<caption_output>Several silhouetted figures move in a dimly lit space with a bright light behind them. The scene cuts to darkness where a figure walks toward a distant light, followed by another dark frame with a figure moving. It

Silhouetted human figures moving via locomotion (walking, running, gesturing) in discrete, solid object interactions. Movement is localized to individuals without fluid or environmental distortion.

No shifting backgrounds or fluid motion (fire, water, smoke, wind). Background elements (walls, ground) appear static with no uniform motion; lighting changes are due to subject movement under light sources.


A person in a plaid shirt uses a tool on a machine, followed by close-up hands adjusting a circular metal component with rapid motion. Next, a person in a dark jacket manipulates a tool at a 45-degree angle on machinery, then hands work on a bike wheel component. The camera maintains close-up perspectives throughout, focusing on the subjects' hands and tools with minimal background details.

A person (in uniform/checkered shirt) and their hands are moving tools and interacting with solid objects (tire, car engine, automotive components) in a workshop setting.

No dominant ambient environmental motion (fire, water, smoke, wind). Background elements (shelves, workshop structures, car body) remain static across scenes without uniform shifting.


A person with brown hair, wearing a red and white striped cardigan over a gray shirt, faces the camera in a room with gray walls and a ceiling fan. The person leans forward slightly, mouth open as if speaking or laughing. The ceiling fan rotates slowly in the background. The camera remains stationary, capturing the person from the front.

A person (solid, distinct object) exhibits head and body movements (nodding, smiling, leaning forward) due to explicit physical actions (facial expressions, locomotion).

Background walls and ceiling are static with no fluid motion (fire, water, smoke) or environmental effects (wind) detected; no uniform background shift observed.


A person wearing a blue polo shirt with a logo gestures by clapping their hands together, then raises one hand to their head, adjusts their position, and brings hands back to a neutral gesture in front of their body. The individual, with dark hair and glasses, stands in front of a wooden door and a wall map. The camera remains static, capturing the subject from a fixed angle.

The man is moving his hands/arms (gesturing) and lifting a glass to his mouth, representing discrete solid-object motion due to explicit physical actions (locomotion/gestures).

The background (wooden door, wall map, floor lamp) remains static with no shifting or fluid environmental motion (fire, water, smoke, wind) observed.


A man in a dark shirt and light pants stands on a grass field, then walks toward a yellow soccer ball. He kicks it, sending it toward the goal; a second person in dark clothing runs to the goal as the ball approaches. The camera follows the ball’s trajectory with a slight pan.

A man in a dark shirt kicks a yellow soccer ball, causing it to move. The ball rolls across the field and is later kicked again (blue ball appears). Another person near the goalpost moves slightly but is not the primary subject.

Static background elements (fence, goalpost, banners) show no uniform shifting; no fire, water, smoke, or significant wind motion observed. Grass and trees are stationary.


The video displays three split screens: top left shows a game screen with fluctuating numerical values, center features a person in a white shirt with a black emblem standing near a screen, and right shows a pinball machine with colorful lights flashing and a moving ball. The numerical values on the game screen change, the person remains stationary, and the pinball machine’s lights and ball exhibit continuous motion. Camera perspective is static with three fixed panels.

A person in the left panel moves their arm/hand repeatedly, showing distinct locomotion without environmental influence.

Background elements (walls, structures) remain static; no fluid motion (fire, water, smoke) observed. Right panel's lights are static decorative elements.


A person with curly red hair and a black sleeveless shirt raises both hands to gather and twist their hair into a bun, moving from their face upward against a white tiled wall with a radiator behind them; the camera remains stationary throughout the sequence.

A person's hands are actively manipulating their hair through pulling, tugging, and repositioning motions, demonstrating solid object movement driven by physical forces.

Background (wall, radiator) is static with no shifting or environmental motion (e.g., no fire, water, smoke, or wind visible).


A man in a black shirt and dark shorts walks toward a blue bucket placed against a white wall. He approaches the bucket, reaches for a gray cloth on a window ledge, and lifts it into his hand. The camera follows his movement with a slight shake, maintaining focus on him as he stands in front of the bucket and window.

A man walks towards a blue barrel, picks up a metallic object (flat, possibly a sheet or plate) from a railing, and examines it. His motion is due to walking and handling the object.

No shifting background or fluid/environmental motion (e.g., fire, water, wind). Background (wall, railing, barrel) remains stable.


A baby wearing a light blue shirt and having light hair sits on a beige couch, initially looking to the right before turning to face the camera and smiling, with hands resting on the couch. The baby's movement is followed by a close-up camera that slightly adjusts to maintain focus on the baby's face and upper body, with minimal background elements visible.

A baby is actively moving its head and upper body, exhibiting distinct locomotion and facial expressions.

Background elements (couch, blanket, furniture) are static with no shifting or fluid motion; no fire, water, smoke, or wind observed.


RAW CAPTION: Got it, let's break this down. First, the video shows kids around a small object on the ground. Let's look at the sequence.

In the first frame, a child with curly hair and a red shirt is pointing at a blue object. Then, the camera shifts to show more kids: one with a blue shirt and green pants (kneeling, hands on ground), another with blue jeans and white sneakers. They're all focused on the ground. The kids are crouching or sitting, their hands moving towards the blue object. The background is the ground, maybe dirt or concrete.

Chronologically: The kids gather around the object. One child points, others lean in. Their hands are near the object, maybe picking it up. The camera moves a bit, maybe a slight tilt or pan. The main action is the children interacting with the small blue object on the ground.

Need to describe the motion: kids bending down, hands moving, focusing on the object. Appearance: various kids, different clothes (red, blue, orange vest, jeans, sneakers). Spatial: close together, all around the object. Camera: starts close-up, maybe slight movement as it follows the kids' actions.

Make sure to follow the rules: chronological order, motion, appearance, spatial, camera perspective. Keep it concise. Let's draft:

Several children, including one in a red shirt with curly hair and another in blue jeans and white sneakers, gather closely around a small blue object on the ground. They bend down, hands reaching toward the object, some touching or moving it. The children’s hands and lower bodies are visible as they interact with the item, shifting positions while focused on the ground. The camera maintains a close-up, slightly shifting to capture the group’s actions from a low angle.

Wait, check the rules. Background minimal. So maybe "dirt ground" but not essential. Let's refine. Focus on motion and behavior.

First, the kids are around the blue object. Then, hands move. So:

Children in varied clothing (red shirt, blue jeans, orange vest) gather around a small blue object on the dirt ground. They bend down, hands reaching toward the object; some touch or move it, others shift positions. The camera stays close, slightly adjusting to follow the children’s movements from a low angle.

Check if chronological: start with gathering, then interacting. Yes. Mention number: several children. Appearance: different clothes. Spatial: around the object. Camera: low angle, close-up, slight movement.

Let me check the examples. The sample output should be a paragraph. Let's make sure it's concise.

"Several children gather around a small blue object on the ground, bending down with hands reaching toward it. One child in a red shirt points, others in blue jeans and white sneakers lean in, shifting positions as they interact with the object. The camera maintains a low, close-up perspective, slightly adjusting to capture their movements."

Wait, the video starts with the first frame showing a child pointing, then others. Let's check the sequence:

Frame 0: child with curly hair (red shirt?) points at blue object.

Frame 1: hands of kids around the object.

Frame 2: child in blue shirt, green pants kneels, hands on ground.

Frame 3: more hands, blue object.

Frame 4: child points, others look.

So motion: kids are crouching, pointing, moving hands towards the object.

Final caption should be chronological. So:

Children in various outfits (including red shirt, blue jeans, orange vest) huddle around a small blue object on the dirt ground. They bend down, hands moving toward the object; some touch or adjust it while others shift positions. The camera captures close-up shots of their hands and lower bodies from a low angle, slightly shaking as it follows the group’s actions.

But "slightly shaking" might not be necessary. The rules say camera perspective and movement. So "low angle, slight movement (pan/tilt)".

Wait, the problem says "Conclude with the camera perspective and movement (e.g., top-down, pan left, slight shake)."

So need to mention that.

Possible:

Multiple children, including one in a red shirt with curly hair and another in blue jeans and white sneakers, gather closely around a small blue object on the ground. They bend down, reaching hands toward the object; some touch or move it while others adjust their positions. The camera remains in a low, close-up view, slightly shifting to follow the children’s interactions.

But check the rule: "keep background descriptions minimal unless essential for understanding motion." Ground is part of the setting, so maybe mention "dirt ground" but only if necessary. In the video, the ground is visible, but the motion is the kids interacting with the object, so ground is background but needed? Maybe. Let

Children's hands and feet are moving on the ground, interacting with a chalk piece.

The ground and background are static; no fluid/environmental motion (fire, water, smoke, wind) is present.


A marching band in green uniforms advances forward in a coordinated formation, led by two individuals carrying a large green banner. The ensemble moves in unison along a street, with musicians playing brass and woodwind instruments, while spectators line the sidewalks. The camera maintains a steady tracking perspective, following the band's forward motion without significant shifts.

Discrete solid objects: Parade participants in green uniforms (carrying banner for Cassidy High School) moving in coordinated motion. Crowd members in the background also exhibit individual locomotion but lack the unified movement of the parade group.

The background (street, buildings, distant structures) shows no uniform shifting or fluid motion. No fire, water, smoke, or wind-driven effects are dominant; the environment remains stable with no environmental fluid dynamics.


A hand uses a spoon to add white butter into a metal pot containing a liquid. Then the hand pours dark cocoa into the pot. The pot is placed on a stove, stirred while boiling over high heat. After two minutes of boiling, the pot is removed and the dark liquid is poured into a white bowl. The camera remains top-down, focusing on the pot and then the bowl.

A human hand is actively stirring the mixture in the pot, causing the liquid to swirl.

The background (stove and countertop) is static. The fluid motion in the pot is a result of stirring and boiling, which is driven by an external force (the hand) and not dominant ambient motion.


A small child, seated on a patterned rug, is fed by an adult's hand that brings food to the child's mouth. The child eats, then the hand retracts slightly while the child continues to sit. The child wears light-colored clothing and is positioned in front of a red tricycle and blue ball in the background. The camera remains stationary with minimal movement, capturing the interaction from a direct angle.

A hand is moving toward and interacting with a seated child, indicating discrete object motion due to physical feeding action. The child exhibits minimal movement relative to the hand's interaction.

The background elements (rug, toys, furniture) remain static across frames, showing no uniform shifting or fluid/environmental motion (e.g., no fire, water, or wind effects).


A boy in a blue and white striped shirt and patterned shorts rides a small bicycle with green wheels along a dirt path. He loses balance, falls off the bike, which rolls a short distance before stopping. The boy rolls on the ground, then pushes himself up to his feet. The camera follows the action with slight handheld movement, capturing the scene from a medium distance.


A person wearing brown sandals and blue jeans stands to the left, their foot visible as a large, spinning silver cutting wheel interacts with a gray stone block. A hand holding a green tool guides the wheel, which cuts through the stone, creating cracks. The wheel moves upward, revealing more of the stone's fractured surface. The camera maintains a steady close-up perspective focused on the wheel and stone interaction.

The primary discrete object moving is the cutting tool (circular saw) being operated by a person's hand. The tool rotates and translates to cut the concrete block, causing fragments to break off.

The background (concrete ground and surrounding objects) remains stable with no shifting, and there is no fire, water, smoke, or wind present.


A woman in a light blue shirt with a floral pattern holds a microphone, speaking and gesturing with her right hand while seated among other attendees in red auditorium seats. Surrounding her, several people—including individuals in pink, white, and orange tops—sit facing forward or toward her, some observing her actions. The scene remains static with no significant camera movement, maintaining a consistent focus on the woman and the seated audience in the foreground.

The central subject (a woman) exhibits controlled gestures and slight body movements while speaking into a microphone. Surrounding audience members show minimal, isolated motions (e.g., head turns, hand gestures) but remain largely seated.

The background consists of stationary red seats and static human figures with no fluid motion (e.g., fire, water, smoke, wind). Background elements show no uniform shifting or environmental movement.


A hand holds a thumb, positioning a small knife near the nail; another hand then brings a blue nail clipper to trim the thumb nail. The blue clipper is positioned above the thumb. The background is a textured burlap surface. The camera maintains a top-down perspective.

A hand holds a small object while a knife is used to cut/scrape it; both hand and knife exhibit controlled physical movement.

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


A man wearing an orange polo shirt sits indoors, facing the camera. He raises his right hand in a wave, then brings both hands together in front of him, followed by pointing with his right index finger. He subsequently opens both hands with palms facing forward and points again with his right hand. The background includes an office space with desks and framed pictures on the wall behind him. The camera remains static throughout.

A person in an orange shirt performs discrete hand and arm movements (waving, gesturing, holding an object). These actions involve solid objects moving due to explicit physical forces (locomotion/gestural motion).

Background elements (walls, framed pictures, office furniture) remain static and show no uniform shifting or fluid motion (fire, water, wind). No ambient environmental phenomena are present.


Players in yellow and white/purple jerseys collide near the goal line; the white team attempts to advance the ball while yellow defenders surround and tackle the ball carrier, causing him to fall to the ground, with the camera maintaining a top-down perspective.

Football players in yellow and purple jerseys exhibit motion from physical collisions, tackles, and locomotion. Players are engaged in discrete, solid-object interactions (e.g., tackling, falling) that can be tracked with bounding boxes.

The football field background (yard lines, '1st & Goal' sign) remains stable with no shifting or fluid motion. No fire, water, smoke, or wind effects are present.


A man in a blue polo shirt and khaki pants stands on a green golf course, holding a golf club in his left hand. He gestures with his right hand, pointing toward a sand bunker to his right, then moves his right arm in a sweeping motion. The background shows green grass, trees, and a sand trap. The camera follows his movement with a slight pan to the right.

A person (Dale Broughton) is moving via hand gestures and slight body shifts while speaking; discrete solid object motion.

Background elements (grass, trees, path) are static with no shifting or fluid motion; no fire, water, smoke, or wind is dominant.


A person wearing a yellow vest uses a metallic power wrench with red handles, manipulating it with both hands to tighten or loosen components. The hands move the wrench in a controlled motion, adjusting its position as the individual works. The camera maintains a close-up perspective focused on the wrench and hands, with slight adjustments to follow the motion of the tool.

Hands manipulating a metallic tool (pliers) with deliberate movements; no fluid or environmental motion observed in solid objects.

Background elements (yellow vest, static environment) show no uniform shifting; no fire, water, smoke, or wind detected.


RAW CAPTION: Got it, let's tackle this video captioning task. First, I need to watch the video and note the main elements. The video starts with a person in a white shirt with a blue stripe, holding a small bouquet of yellow flowers in a red vase. They're clapping or making hand gestures. Another hand enters from the left, also moving. The background has a white room with a plant on a table and vertical blinds.

Wait, the video sequence: at 0.0, the person is in the frame, hands moving. Then the left hand comes into view. The person continues gesturing, maybe clapping. The other hand (left) is also moving. Need to describe motion chronologically.

Main subjects: two people (one visible mostly, the other's hand). First person is wearing white shirt, holding yellow flowers in red vase. The other hand is from another person, entering from left.

Spatial relationships: the first person is on the right, the other hand from left. Background has vertical blinds, a plant on a table, and a white wall.

Camera perspective: seems like a handheld shot, maybe slight shake. The camera is positioned so that the first person is close to the frame, and the other hand comes into view.

Now, structure the caption: start with the first subject's action, then the second. Mention their appearance, motion, then background briefly, camera.

Check rules: chronological order, motion and behavior, appearance, spatial, camera.

Let me draft:

A person in a white shirt with a blue stripe holds a small red vase with yellow flowers, gesturing with both hands toward the camera. Another person’s left hand enters from the left side of the frame, moving rhythmically. Both subjects’ hands continue clapping-like motions. The background includes vertical blinds and a plant on a table. The camera remains stationary with slight movement.

Wait, but the video's first frame: the person is smiling, hands up. Then the other hand comes in. Let's check timestamps:

0.0: person in white shirt, holding flowers, hands moving (clapping?)

0.1: same, hands up.

0.2: left hand enters.

0.3: both hands are open, facing each other.

0.4: person leans forward, hand gestures.

0.5: similar.

So the main actions: the person with the flowers is clapping, then the other hand joins, and they both gesture.

Now, appearance: first person is wearing a white shirt (maybe short-sleeve), the flowers are yellow, vase red. The other hand is from another person, so not fully visible, but a hand.

Spatial: the first person is on the right, the left hand comes from the left of the frame.

Background: vertical blinds on the left, white wall, plant on a table, sofa with cushions.

Camera: seems like a fixed position but slight shake, maybe handheld.

Need to keep background minimal. So "background includes vertical blinds and a plant on a table."

Putting it all together chronologically:

A person in a white shirt with a blue stripe holds a red vase with yellow flowers, making hand gestures toward the camera. Another person’s left hand enters from the left, moving rhythmically. Both subjects’ hands continue clapping-like motions, with the first person occasionally leaning forward. The background features vertical blinds and a plant on a table. The camera remains in a stationary position with slight shake.

Wait, check if "stationary" is correct. The video might have a bit of movement, but the description says "slight shake." So "stationary with slight shake" might not be right. Maybe "held steady with minor movements."

Wait, the task says: "conclude with the camera perspective and movement (e.g., top-down, pan left, slight shake)."

So the camera is likely handheld, so slight shake. Let's adjust:

A person in a white shirt with a blue stripe holds a red vase with yellow flowers, making hand gestures toward the camera. Another person’s left hand enters from the left side of the frame, moving rhythmically. Both subjects’ hands continue clapping-like motions, with the first person occasionally leaning forward. The background includes vertical blinds and a plant on a table. The camera maintains a fixed perspective with slight shake.

Wait, the background: "minimal unless essential." So "background features vertical blinds and a plant on a table." Maybe that's okay.

Let me check the example: "background includes vertical blinds and a plant on a table."

Now, check for conciseness. Need to be concise.

Alternative:

A person in a white shirt with a blue stripe holds a red vase of yellow flowers, gesturing with both hands. Another person’s left hand enters from the left, moving rhythmically. Both continue clapping motions; the first person leans forward. Background includes vertical

Two people are moving: the person on the right is clapping and making gestures (e.g., leaning forward, bringing hand to mouth), and the person on the left is clapping or gesturing with their hands.

The background (striped wall and white wall) is static and does not shift uniformly. There are no fluid or gaseous motions (fire, water, smoke, wind) in the scene.


A person wearing a white top and red pants sits on the edge of a white boat near a turquoise river, stands up, runs toward the water, and jumps in, creating a splash. The camera remains stationary, capturing the action from the boat's perspective.

A person in a white top and pink pants walks along the platform and jumps into the water. This motion is caused by explicit physical forces (locomotion and gravity), with clear tracking of the subject's movement from platform to water.

The rocky cliffs in the background are static and show no uniform shifting. The water displays a brief splash after the jump, but the dominant motion is not fluid-driven (e.g., waves or currents); it's a transient effect from the discrete object's action.


Two individuals in white karate uniforms with black belts practice martial arts in a room. One person executes a kick toward the other, who holds a wooden board. They shift positions, moving around the space; the kicker then performs a high kick while the board holder raises the board above their head. The background includes a wall with a circular emblem. The camera remains stationary throughout.

Two individuals in white martial arts uniforms are performing discrete physical actions: kicking, blocking, and maneuvering their bodies against each other. Their movements are driven by explicit physical forces (locomotion, collisions between limbs).

The background (wall, floor) shows no uniform shifting or fluid motion (e.g., no fire, water, smoke, or wind). Static elements remain consistent across frames.


RAW CAPTION: Okay, let's tackle this video caption request. First, I need to understand the user's instructions. They want a concise, chronological paragraph describing the video, focusing on the main subjects' motions and behaviors. The rules specify to mention appearance, spatial relationships, camera perspective, and keep background minimal.

Looking at the video frames provided. There are three people: two in white shirts and one in a striped shirt. The main subjects are the drummers. The first two are playing conga drums, which are red with brown heads. The third person is on the right, maybe playing a different drum. They're sitting on a bench against a yellow wall. The floor is wooden.

Chronologically, the video starts with them seated. The two in white are actively drumming, using their hands. The third person might be playing a drum too. The camera seems to be static, no movement mentioned, so top-down or slightly angled? The background is a yellow wall and some items on the floor, but minimal details needed.

Wait, the user says to exclude text recognition and named characters, so no mentioning names. Need to describe their actions step by step. The main motion is drumming. The two on the left are playing conga drums, the one on the right has a different drum. The camera is stationary, so the perspective is probably a fixed shot.

Check the output format: must be inside <caption_output> tags. Need to be concise. Let me structure it:

Three individuals seated on a bench. Two in white shirts play red conga drums with hands; third in striped shirt plays a drum. They drum in sync, hands moving rhythmically. Camera is static, top-down view. Background minimal.

Wait, the user said "chronological paragraph," so maybe start with the initial state, then actions. But since it's a short video, maybe just describe the ongoing action. The frames show them drumming, so the main action is drumming. Spatial: two in front, one to the right. The drums are red. Camera perspective: the video seems to be a medium shot, not top-down. Wait, the first frame shows them sitting, maybe slightly angled. The user mentioned "top-down" in the rules, but in the video, it might be a standard angle.

Wait, the example output in the problem statement uses "top-down" as a possible camera movement. But the user's sample doesn't specify. Let me check the rules again. The camera perspective should be mentioned. The original video description says "top-down" but maybe it's not. Wait, the user says "keep background descriptions minimal unless essential for understanding motion." The background is yellow wall and wooden floor, which might be essential for context, but the rules say minimal. So maybe just mention the yellow wall as part of the setting.

Wait, the instruction says to mention spatial relationships if relevant. So two people playing conga drums in front of the third? Or the third is to the right. Let me see: the two in white are on the left side, the third person in striped shirt is on the right, next to a drum. So "two individuals in white shirts play red conga drums while a third in a striped shirt plays a drum to their right."

The caption should be concise. Let me try:

Three individuals seated on a bench; two in white shirts play red conga drums rhythmically with their hands, while a third in a striped shirt plays a drum to their right. Camera remains static, capturing a medium shot with a yellow wall in the background.

Wait, but the user wants chronological order. So starting from the initial frame. The first frame shows them sitting, then they start drumming. But the video is short, so maybe the action is continuous. The caption should describe the ongoing action.

Another way: The three individuals are seated on a bench against a yellow wall. The two in white shirts actively drum on red conga drums, moving their hands rhythmically. The third person, wearing a striped shirt, plays a drum to the right. The camera maintains a static, slightly angled perspective throughout.

Check the rules: exclude text recognition, no named characters. Use minimal background. Mention spatial relationships. The camera perspective: "static, slightly angled" is acceptable. The key is to keep it concise.

Maybe: Two individuals in white shirts play red conga drums while seated on a bench, accompanied by a third person in a striped shirt playing a drum to their right. All drummers rhythmically strike their instruments; the camera remains static with minimal background details.

Wait, the user says "chronological paragraph." So starting from the beginning: In the video, three people sit on a bench. Two in white shirts start playing red conga drums, and the third person in striped shirt begins playing a drum. They continue drumming rhythmically, with the camera maintaining a static shot from a medium perspective.

Three people are actively playing conga drums, moving their hands and arms to strike drumheads in distinct, rhythmic patterns; the drums themselves are stationary.

The yellow wall and wooden floor background remains static with no fluid motion (fire, water, smoke) or environmental sway; no signs of wind or gaseous movement.


A man in a yellow vest and beige cap adjusts white bags on a pallet, lifting one to his chest before standing and handing it to another individual wearing a green jacket and blue jeans. The second person receives the bag and steps back, moving it away from the pallet. The interaction occurs in a workshop setting with stacked wooden pallets visible in the background. The camera remains stationary, capturing the action from a fixed angle.

Two individuals are moving: one applying material to a large surface (locomotion and tool use), the other walking and interacting with the scene (physical displacement).

Static background elements (wooden pallets, concrete walls) show no uniform shift or fluid motion; no fire, water, smoke, or wind detected.


A person in a blue sweater over a collared shirt stands inside a cabin with wooden cabinets and a window. They turn their head, reach toward the counter, pick up a white cup, and lift it toward the camera. The background includes a window showing an outdoor view and a countertop with items. The camera remains mostly static with slight movement.

The man is moving his head, shoulders, and arms while speaking and gesturing.

The background (wooden cabinets and window) is static; no ambient environmental motion (fire, water, smoke, wind) observed.


Two hands grip a round orange with textured orange peel. The left hand holds the orange stationary while the right hand uses a yellow-handled tool with a black blade to carefully slice through the peel, removing small sections around the top surface. The orange remains held firmly as the tool moves methodically along its circumference. The camera maintains a close-up, steady shot focused on the hands and orange against a neutral background.

Hands are actively manipulating an orange with a tool (likely a knife), exhibiting deliberate, physical interaction (e.g., scoring or cutting the fruit).

Background appears as a static, plain surface with no visible shifting or environmental fluid motion (e.g., no fire, water, smoke).


A woman wearing a black crop top and denim shorts hula hoops on a grassy lawn in front of a white house with a sloped roof. She begins with arms raised, lifting the hoop above her head, then moves it down to spin around her waist as she steps forward. The background includes flowering plants and a bench, but the camera remains stationary, capturing her motion from a fixed eye-level perspective.

A single human subject is performing discrete locomotion: jumping, kicking, and running across the garden. These actions involve solid-body movement driven by physical forces (muscle contractions, gravity).

Background elements (houses, garden structures, plants) show no uniform shifting or fluid motion; no fire, water, smoke, or significant wind-driven environmental effects are visible.
