RAW CAPTION: Got it, let's tackle this. First, the video shows a meat grinder. In the first frame, it's grinding chicken into a glass bowl. Then the second frame continues that, maybe adding more. Then the third frame splits into three panels: chicken, fish, pork each being ground into separate bowls.

Need to focus on motion and chronological order. Start with the chicken grinding: a red meat grinder with a black gear extrudes ground chicken into a clear glass bowl. Then the scene transitions to three panels showing chicken, fish, pork being processed similarly. The meat grinder is red with a black gear, each time extruding different meats into clear bowls.

Background is minimal, maybe kitchen setting but not necessary. Camera perspective: initial close-up on the grinder and bowl, then split-screen. Need to mention the sequence: first chicken, then the three meats. Also, the bowls are clear, below the grinder.

Check rules: don't include text like "CHICKEN" but the captions have "CHICKEN" as text, but rule g says exclude text recognition. Wait, the problem says "Exclude text recognition, named characters, or stylistic analysis." So ignore the text labels like "CHICKEN" that are on the screen.

So focus on the objects: red meat grinder, black gear, ground meat (different types) being pushed into clear glass bowls.

Chronological order: First, the grinder processes chicken (light-colored meat) into a glass bowl. Then, the video shows three panels: left (chicken), middle (fish), right (pork), each grinder extruding respective ground meats into separate glass bowls.

Spatial: The grinder is positioned above the glass bowls. The bowls are in front of the grinder.

Camera: Initial close-up, then split-screen showing three sections.

Now, write concise paragraph.

Start with the main action: A red meat grinder with a black gear extrudes ground chicken into a clear glass bowl. The scene transitions to a split-screen view displaying three sections: the left section shows the grinder processing chicken, the middle section processes fish, and the right section processes pork, each extruding respective ground meats into separate clear glass bowls.

Wait, need to check chronological order. The first frame is chicken, then second frame continues, then third frame is split into three. So sequence: first, the grinder processes chicken (as labeled, but exclude text), then the video shifts to show three different meats in panels.

So: Initially, a red meat grinder with a black gear pushes ground chicken into a clear glass bowl. Subsequently, the video splits into three panels, each showing the same red meat grinder processing different meats—chicken, fish, and pork—into separate clear glass bowls.

But rule b: mention appearance and number. The grinder is red, black gear. The meat: chicken (light), fish (pale pink?), pork (light pink). But since we can't include text, maybe describe by color.

Wait, the problem says "briefly describe their appearance and number (color, size, orientation)." So for the meat: ground chicken (light beige), fish (pale pink), pork (pale pinkish).

But maybe keep it general: ground meat of varying colors (light beige, pale pink) is extruded.

Let's draft:

A red meat grinder with a black gear extrudes ground chicken into a clear glass bowl. The scene then transitions to a split-screen displaying three sections: left section shows the grinder processing light beige ground chicken, middle section processes pale pink ground fish, and right section processes pale pink ground pork, each into separate clear glass bowls. The camera remains static in close-up during the initial sequence and shifts to a split-screen layout for the subsequent frames.

Check rules: background minimal, so don't mention kitchen unless essential. The background is blurred but not essential. Camera perspective: close-up, then split-screen.

Wait, the first part is a single frame (chicken), then another (more chicken), then split. So chronological: first, the grinder dispenses chicken into a bowl. Then, the video shows three panels: chicken, fish, pork each being processed.

Final caption:

A red meat grinder with a black gear extrudes ground chicken into a clear glass bowl. The video then splits into three sections: the left shows the grinder processing chicken, the middle processes fish, and the right processes pork, each extruding ground meat into separate clear glass bowls. The camera maintains a close-up view throughout the initial sequence and transitions to a split-screen format for the subsequent frames.

Wait, but rule f says exclude text recognition. The original video has "CHICKEN" text, but we shouldn't mention that. So instead of "left shows chicken", just describe the meat. But how? Maybe "light-colored ground meat" for

A red masher device extrudes solid food items (chicken, fish, pork) into glass bowls, showing discrete movement of the food material due to mechanical action.

Background elements (red device, glass bowls, wooden utensil) are static; no shifting backgrounds or fluid/environmental motion (fire, water, smoke, wind) detected.


Two girls hop across a hopscotch court; one wears a pink top and pants, the other a dark sleeveless top with geometric-patterned pants. The girl in pink leads, followed by the second girl as they move leftward. The camera pans left, following their progression, with other people visible in the distant background.

Two girls are actively hopping and jumping on a hopscotch grid, demonstrating clear locomotion. Other distant figures show minimal movement but are not primary subjects.

Background elements (court lines, basketball hoop, distant trees and people) show no significant fluid motion (fire, water, smoke) or wind-induced swaying. Background appears stationary; minor camera adjustments are present but not uniform shifting.


A large crowd of diverse individuals, dressed in casual clothing of various colors, energetically dance in unison at a nightclub stage. They raise arms, sway, and move rhythmically, mirroring the dancers displayed on the central screen. Throughout the sequence, the crowd maintains synchronized motion, with some individuals shifting positions while others remain in the foreground. The camera, positioned at a slight angle, captures the dynamic scene with minimal movement, focusing on the collective movement of the dancers.

People (discrete, solid objects) moving via dancing, swaying, and arm-raising motions, indicating explicit locomotion and physical force interactions.

No shifting backgrounds; no fluid/environmental motion (fire, water, smoke, wind) observed. Stage elements (lights, screens) remain static across frames.


A person in a light jacket and dark pants snowkites across a snowy field, holding a colorful kite aloft. They move from the right toward the center, passing a red barn in the background, with the camera following their motion as they glide smoothly over the snow.

A snowboarder (discrete solid object) moves across the snowfield, exhibiting controlled locomotion with visible turns and speed changes while holding a kite control bar.

The snowy field and building background remain static throughout the sequence; no fluid or gaseous motion (fire, water, smoke) is observed. The kites in initial frames move due to wind but are secondary and not dominant.


A person wearing a dark gray button-up shirt holds a long, flexible tube with blue and green hues. They stretch the tube horizontally in front of their torso, then lift it upward while maintaining tension, moving the tube from a horizontal to a vertical orientation. The background includes faintly visible chairs but remains unobtrusive. The camera maintains a close-up perspective focused on the hands and tube, capturing the motion without significant movement or shake.

A blue tube (solid object) is being bent and held by a person. The motion is due to the person's hands manipulating the tube.

The background includes a chair and wall which remain static; no fire, water, smoke, or wind is present. Ambient environmental motion is absent.


A woman with long dark hair and a pink swimsuit sits at the edge of a frozen ice hole, using a metal ladder to enter the icy water. She steps into the hole, moving forward and submerging deeper as she swims, with her body partially submerged in the dark water. Several people stand nearby on the snowy ground, observing her descent. The camera follows her movement with a slight shake, capturing her progression from the ladder into the icy depths.

A single person (woman) moves from sitting at the hole's edge to submerging and swimming in the water, demonstrating discrete locomotion via physical exertion.

The background (snow-covered ground, static wooden structure, and standing people) shows no shifting or fluid motion. Water in the hole is still with minor ripples from the woman's movement, not dominant environmental flow.


RAW CAPTION: Got it, let's tackle this captioning task. First, I need to follow the rules. Let's go through the video frames.

The first frame shows a group of people in a dance studio. There are several individuals: let's count—around 8 people? They're standing in a line or group, maybe dancing. The background has a white room with barres and some framed pictures. Then the next frame (1.4s) shows the group moving, maybe stepping or dancing. The third frame (2.5s) is a close-up of a person with a white knit beanie, braid, wearing a denim jacket. Then frame 3.6s shows close-up of feet, some wearing socks, dancing. Then frame 4.7s is another person, maybe a different angle, standing in the room.

Wait, need to describe in chronological order. So the video starts with a group of people dancing in the studio. Then transitions to a close-up of a person with a beanie, then feet dancing, then another person. Need to mention number, appearance. Let's check the numbers. First frame: multiple people (approx 8). Then close-up of one person with beanie. Then feet of multiple people (different feet, maybe different people). Then a person in a brown top.

Background: dance studio with barres, white walls, some pictures. But rule e says minimal background unless essential. So maybe just mention "dance studio" briefly.

Chronological: first, group of people dancing; then close-up of a person with beanie; then close-up of feet moving; then close-up of another person.

Camera perspective: starts with wide shot, then close-ups, maybe pan or cut.

Let's structure it:

The video opens with a group of eight people dancing in a bright dance studio, moving in unison. A person wearing a white knit beanie and denim jacket is shown in close-up, followed by shots of dancers' feet in motion, including those in white socks and sneakers. The sequence then features a woman in a brown top standing in the studio. The camera shifts between wide shots of the group and close-ups of individuals and their movements.

Wait, check the frame times. The first frame is [0.0], then [1.4] shows group moving, [2.5] is the beanie person, [3.6] feet, [4.7] another person.

So chronological order:

- Initially, a group of people (approx 8) dance together in the studio.
- Then, close-up of a person with a white knit beanie, braided hair, and denim jacket.
- Next, close-up of dancers' feet (various socks and shoes) moving.
- Finally, a person in a brown top standing in the studio.

Camera movement: starts with a wide shot, then cuts to close-ups.

Now, follow the output format. Must be a paragraph, concise, chronological.

Let's draft:

The video begins with a group of approximately eight people dancing in a dance studio, moving in unison. It then cuts to a close-up of a person wearing a white knit beanie and denim jacket, followed by shots of dancers' feet in motion, including those with white socks and sneakers. The sequence concludes with a woman in a brown top standing in the studio. The camera transitions between wide shots of the group and close-ups of individuals and their movements.

Check rules:

a) Motion and behavior: dancing, close-ups of movement.

b) Number: approx 8 people, then individual details.

c) Spatial: group in studio, close-ups.

d) Camera perspective: wide shot to close-ups.

e) Background minimal: "dance studio" is essential for understanding, but minimal. The studio has barres, but maybe "in a dance studio" is enough.

f) Exclude text: no text in video, so okay.

g) Think internally, but output as per.

Let me adjust to be more concise:

A group of about eight people dance together in a dance studio. The video then shows a close-up of a person wearing a white knit beanie and denim jacket, followed by close-ups of dancers' feet moving, including those in white socks and sneakers. It ends with a person in a brown top standing in the studio. The camera shifts from wide shots of the group to close-ups of individuals.

Wait, need to mention the number. "Approximately eight people" is good. Also, the chronological order: first group dancing, then beanie person, then feet, then brown top person.

Check the frames: [0.0] group, [1.4] group (maybe moving), [2.5] beanie, [3.6] feet, [4.7] brown top. So yes.

Also, appearance: white knit beanie, denim jacket;

Dancers are moving through the studio space; feet movements are shown in close-ups, indicating locomotion due to physical forces.

The background (dance studio walls, mirrors, barres) is static and does not shift uniformly. There is no fire, water, or wind motion.


Two workers in green uniforms and caps work in a factory with stacked sacks in the background. One worker stands near a table with items, while the other maneuvers a pallet toward the first worker. The second worker pushes the pallet forward, adjusting its position relative to the table. The camera pans left slightly during the sequence, maintaining a medium shot of the workers and surrounding industrial equipment.

People in green and blue uniforms moving and handling boxes/pallets.

Background (pallets, walls) is static; no shifting. No fire, water, smoke, or wind observed.


RAW CAPTION: Okay, I need to create a concise chronological paragraph describing the video based on the provided frames. Let me start by analyzing the given frames.

First, the video shows a large truck with its rear doors open. Inside the truck, there are stacked wooden pallets, maybe with some boxes on them. The truck is stationary, and there's a red fire extinguisher attached to the side near the open doors. Then, two workers in blue uniforms and helmets are walking towards the truck. They're approaching from the right side of the frame. The text on the screen mentions "Sin RAMPA DE PATIO" which translates to "Without yard ramp," and lists some statistics like 10 movements and 2 workers involved. But according to the rules, I should exclude text recognition, so I'll ignore that.

Next, the workers start moving towards the truck. The camera seems to be panning slightly to the left, focusing on the truck's interior as the containers are visible. The workers are approaching the open back of the truck, and their movements are towards the truck. There's a mention of a slight shake in the camera movement, but I need to check if that's part of the description.

Wait, the video shows the truck's back doors open, and then the workers are seen walking towards it. The camera moves a bit to show the contents inside the truck. The workers are moving from the right side of the frame towards the left, approaching the truck's rear. They are two individuals, wearing blue uniforms and helmets. The fire extinguisher is on the left side near the truck's door.

I need to structure this in chronological order. First, the truck is shown with open doors, then the workers enter the frame. They move towards the truck. The camera might pan left to show the interior of the truck. The background has a white wall and some greenery, but the rules say to keep background minimal unless essential. So maybe just mention the white wall as part of the setting.

Wait, the user said to exclude text recognition, so the text on the screen isn't part of the caption. So the focus is on the moving elements.

Let me draft it:

The video opens with a stationary large truck with its rear doors open, revealing stacked wooden pallets inside. Two workers in blue uniforms and helmets approach from the right side of the frame, moving towards the truck's open rear. The camera pans left slightly to show the interior of the truck as the workers continue their approach. The background includes a white wall, with minimal other details visible.

Wait, but the workers are moving towards the truck. The original frames show them walking towards the truck, so maybe "approach" is correct. Also, the fire extinguisher is visible on the left side near the truck's door. But the rules say minimal background, so maybe include the fire extinguisher as part of the truck's surroundings.

Wait, the fire extinguisher is part of the truck's exterior. So "a red fire extinguisher is mounted on the truck's side near the open doors."

But the user's rules say to mention spatial relationships if relevant. So the fire extinguisher is to the left of the truck's door.

But maybe the caption should be more focused on motion. Let's check the rules again.

Focus primarily on motion and behavior of main subjects in chronological order. So the main subjects are the truck and the workers.

The truck is stationary, the workers are moving towards the truck.

Chronological order: first, the truck is shown with doors open, then the workers walk towards it.

The camera movement: the first frame shows the workers on the right, then as the video progresses, the camera pans left to show the interior of the truck.

So the caption should start with the truck being stationary, then the workers moving towards it, camera panning left.

Wait, the initial frames show the workers on the right side approaching. The camera movement might be a slight pan left to show the truck's interior.

So the paragraph would start by describing the truck's open doors and contents, then the workers approaching, camera moving slightly left.

Possible caption:

A large truck with its rear doors open displays stacked wooden pallets inside. Two workers in blue uniforms and helmets approach from the right, moving toward the truck's open rear. The camera pans slightly left, revealing more of the truck's interior as the workers continue their approach, with a red fire extinguisher visible on the truck's side.

Wait, the fire extinguisher is part of the truck's exterior. But the user says minimal background. However, since it's a key element in the scene (as it's visible in the frames), maybe include it.

But according to the rules, exclude text recognition and focus on motion. So maybe it's okay to mention the fire extinguisher as part of the truck's surroundings.

Alternatively, since the user said "keep background descriptions minimal unless essential," maybe the

A person in blue attire is moving horizontally across the frame from right to left; this is a solid object exhibiting locomotion (walking) without collision or environmental interaction.

Static background elements (wall, fire extinguisher, structural supports) show no uniform shifting. No fire, water, smoke, or wind-driven fluid motion observed.


A single person descends from a balcony on a tall concrete apartment building, moving sequentially to lower balconies across the video frames. The camera maintains a low-angle perspective, slightly panning to track the person’s downward motion against the building's exterior.

A person is falling from a high floor of the building, representing a solid, discrete object in motion due to gravity.

The background (building and sky) is static with no fluid or environmental motion (fire, water, wind) evident. The building structure remains fixed in the frame.


An individual in a red and white shirt plays a white flute, blowing into the mouthpiece while their fingers cover and adjust the instrument's finger holes; the flute is held horizontally in front of their face, with a wooden chair partially visible to the left. The camera remains stationary, capturing a close-up of the upper body and instrument against a plain wall background.

A person (wearing a red and white shirt) is actively moving their hands to play a flute, with fingers pressing keys and the flute itself exhibiting discrete motion due to physical interaction.

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


RAW CAPTION: Okay, let's tackle this. The user wants a caption for the video. First, I need to follow the rules given. Let me read through the rules again.

Rule a says focus on motion and behavior of main subjects in chronological order. The main subject here is a hand. The video shows a hand moving over a scrapbook or album. So the sequence is the hand moving, maybe flipping pages or pointing to something.

Rule b: Describe appearance and number. The hand is a person's hand, probably light skin tone. The objects on the page: there's a blue clipboard, patterned paper with geometric designs, a butterfly, maybe some stickers or buttons. The background has a white surface with patterns.

Rule c: Spatial relationships. The hand is moving over the album, which is placed on a surface. The blue clipboard is to the left, the hand moves from left to right across the pages.

Rule d: Camera perspective. The video seems to be a top-down view, maybe a close-up. The camera is static, but maybe slightly shaky as it follows the hand's movement.

Rule e: Minimal background. The background is a white surface, so maybe just mention it's a flat surface.

Rule f: Exclude text, named characters, or stylistic analysis. The text "Kamynacha" is in the video, but according to the rules, I shouldn't include that.

Now, the video starts with the hand on the album, then the hand moves across the pages, flipping or pointing. The pages have various patterns, the blue clipboard is there, maybe the hand is arranging or moving items.

Let me structure the caption chronologically. Start with the hand's action: a hand with light skin moves over the album's surface. Then, the hand interacts with objects like the blue clipboard on the left, pointing to or moving a small decorative item. The pages have different patterns. The camera is top-down, maybe following the hand's movement.

Need to check if the hand is the only main subject. Yes, since it's moving over the album. The objects on the album are part of the scene but not main subjects. The hand's motion is key.

So the caption should describe the hand moving across the album, pointing to items, interacting with the clipboard. The camera is top-down, static but following the hand.

Wait, the user said "briefly describe their appearance and number". The hand is one, light skin. The objects: blue clipboard, patterned pages, butterfly, geometric shapes. But maybe mention the main objects as part of the scene but not too detailed.

Putting it all together: A hand with light skin moves across a scrapbook's open pages, shifting from left to right. The hand interacts with a blue clipboard on the left, pointing to a decorative butterfly and patterned sections containing geometric designs and yellow circles. The camera remains in a top-down view, following the hand's movement.

Wait, the user says "mention spatial relationships if relevant". So the hand is moving from left to right, the clipboard is to the left. The butterfly is on the page, maybe the hand points to it.

Check for rules: exclude text, so no "Kamynacha". Keep it concise.

Let me try again. A hand with light skin moves across an open scrapbook, shifting rightward from the left edge. It interacts with a blue clipboard positioned to the left, then points to a decorative butterfly and geometric-patterned sections containing yellow circles. The camera maintains a top-down perspective, following the hand's motion.

Hmm, "geometric-patterned sections containing yellow circles" might be too detailed. The video shows some pages with polka dots and hexagons. Maybe simplify to "patterned pages with geometric designs."

Also, the pages are part of the scrapbook, so the hand is moving over the open pages. Maybe "a hand with light skin moves across the open pages of a scrapbook..."

Wait, the first frame shows the hand on the album. The hand is moving from left to right, maybe flipping a page? Wait, the video is from [0.0] to [5.0] seconds, but the description says the hand moves over the album.

Looking at the frames: [0.0] the hand is on the album, [1.4] the hand continues moving, [3.0] the hand is pointing to a section. The camera might be panning slightly to follow the hand.

The user's example output format is <caption_output>...<caption_output>. So need to make sure it's exactly that format.

Let me check the example. The user provided a sample response, but in this case, it's a different video.

Wait, the instructions say: "DO NOT include any reasoning in the caption tags."

So the final caption should be concise, chronological, describe motion, appearance, spatial, camera.

Let me

A hand manipulates small objects (e.g., buttons, tokens) on a decorative box; the hand's motion is deliberate and interacts with the box's surface.

Background patterns (tree designs, hexagons) remain static; no fluid/environmental motion (fire, water, smoke, wind) detected.


RAW CAPTION: Got it, let's tackle this. First, identify the main subjects. There are two people on stage: one in black, one in white. The video shows them moving. Let's check the sequence.

At [0.0], they're facing each other. Then [0.3] to [5.0], the person in black moves their arms and legs, maybe in a dance or martial arts move. The person in white also moves, arms extended. They're on a stage with some background like trees and a bench.

Chronic order: Two individuals, one in dark attire (black outfit), one in light (white outfit), perform movements. The dark-clad person is on the left, light on the right. They move towards each other, then apart, with arm gestures. Background has plants and a structure, but keep minimal. Camera is static? Or slight movement? The video seems to have a slight shake, maybe handheld.

Now, structure the caption: main subjects, their actions in order, spatial relations, camera.

"Two individuals, one in dark attire and one in light, perform coordinated movements on a stage. The dark-clad figure, positioned left, extends arms and shifts stance while the light-clad figure, right, mirrors gestures. They move toward and away from each other in a rhythmic sequence. Background features sparse foliage and stage elements. Camera remains static with slight shake, capturing the performance from a frontal perspective."

Wait, check the rules. Focus on motion and behavior chronologically. So start with the actions step by step.

At the start, they're facing each other. Then the dark figure moves their arms (like raising them), the light figure also moves. Then the dark figure steps back or forward? Let's see the frames.

Frame 0: both facing each other, arms extended. Frame 1: dark figure moves arms up, light figure moves arms. Frame 2: dark figure steps, light figure shifts. Frame 3: dark figure lowers arms, light figure moves. Frame 4: dark figure extends arms, light figure does too.

So chronological: Two people on stage, one in black, one in white, begin facing each other with arms outstretched. The black-clad individual moves their arms upward and shifts stance, while the white-clad individual mirrors with similar arm movements. They maintain a distance, alternating movements as they step slightly.

Check rules: concise, chronological. Background minimal. Camera perspective: probably a frontal view, maybe slight shake as the video is from a handheld camera.

So the caption should be:

"Two individuals, one in dark attire and one in light, perform coordinated movements on a stage. The dark-clad person, left, and light-clad person, right, begin facing each other with arms extended; the dark figure raises arms and shifts stance while the light figure mirrors, alternating movements as they step slightly. Background includes sparse foliage and stage elements. Camera captures from a frontal perspective with slight shake."

Wait, "begin facing each other with arms extended" is the start. Then the motions.

Another version:

"Two people, one in black clothing and one in white, stand on a stage. The person in black moves arms upward and shifts feet, while the person in white extends arms and steps. They maintain a spatial separation, moving rhythmically. The background features decorative plants and a raised structure. The camera remains static with minor shake, observing from a front angle."

Check if it's chronological. Start with their initial position, then their actions in order.

The video starts with them standing, then moving.

Maybe: "A person in black and a person in white perform on a stage. Initially facing each other, the black-clad individual raises arms and steps forward, while the white-clad individual mirrors arm movements and shifts position. They continue rhythmic motions, maintaining distance. The background includes decorative foliage and stage elements. The camera is stationary with slight shake, capturing the scene from a frontal view."

That's more precise. Let's check the rules again.

a) Motion and behavior in chronological order: yes.

b) Appearance and number: two people, colors noted.

c) Spatial: left/right, facing each other, distance.

d) Camera: frontal, slight shake.

e) Background minimal: mentions foliage and structure but not detailed.

f) Exclude text, names: done.

g) Internal thinking, output as caption.

So final caption should be concise. Let's write it.
</think>

<caption_output>Two individuals, one in dark attire and one in light, perform coordinated movements on a stage. The dark-clad person, positioned left, and light-clad person, right, begin facing each other with arms extended; the dark figure raises arms and shifts stance while the light figure mirrors gestures, alternating

Two human performers in distinct attire (black and white) are executing a choreographed routine involving stepping, squatting, and arm movements.

Background elements (trees, stage structure) show no significant uniform shifting or fluid environmental motion (fire, water, smoke, wind).


The video opens with abstract red and white curved shapes, then transitions to an indoor gymnasium where a woman in a red top, black shorts, and sandals walks across the space. A man in a red shirt, black vest, and dark pants enters from the right, moving leftward while walking. Several other people stand in the background near the walls and doors. The camera shifts from abstract visuals to a steady shot of the gym, capturing the movement of the two main individuals as they walk across the floor.

Two discrete objects: a woman (red top, black shorts) standing in the center and a man (red vest, black pants) walking across the gym floor from right to left. The man's motion is due to locomotion, while the woman remains mostly stationary.

The background (gym walls, floor, doors) is static and shows no shifting. There is no fire, water, smoke, or wind present, so no ambient environmental motion.


A person wearing a blue shirt and jeans holds a maroon electric guitar, gesturing with both hands while speaking. Their hands move upward and downward, occasionally toward the guitar. A small inset video in the top-left corner shows a foot on a blanket. The background is solid black, and the camera remains stationary, facing the person directly.

The person (solid object) is moving their hands and upper body while speaking and gesturing; the guitar is held stationary but the person's body motion is discrete.

Background is static (black backdrop with fixed small image); no fluid or gaseous motion (fire, water, smoke) observed.


A pair of hands interacts with a white sheet of paper; initially, one hand holds the paper while the other points to its content. Subsequently, a hand uses a black pen to write or modify equations on the paper, moving the pen across the surface. The hands maintain close proximity to the paper throughout. The camera remains stationary in a close-up perspective, focusing on the hands and paper with minimal background visibility.

The right hand is writing on the paper, with the left hand holding the paper steady.

The background is not visible, but there is no shifting background or fluid/environmental motion (no fire, water, smoke, wind).


A person with long dark hair, wearing a black t-shirt, sits on a couch with light-colored cushions against a wooden panel wall. They raise their right hand to their face, then cover their face with both hands, lower their hands, raise their right hand again, and finally rest it on their cheek. The camera remains static throughout.

A single person (solid, discrete object) is moving through gestures (touching face, arms, and upper body) with clear locomotion due to intentional physical actions.

The background consists of a static wooden paneled wall and couch cushions with no visible shifting or environmental fluid motion (e.g., fire, water, smoke, wind).


The man stands at a podium, wearing a light-colored shirt and khaki pants, holding a microphone. He shifts his posture slightly, adjusting his stance while speaking. The camera remains static, focused on him against a dark backdrop.

The man (speaker) is the only discrete solid object moving; he is gesturing and shifting position while speaking.

The background consists of a static screen with text and a wooden podium. No fluid motion (fire, water, smoke) or wind-driven motion is observed.


A man in a dark suit, light green tie, and white shirt speaks at a wooden podium, gesturing with his hands; behind him are wooden paneling and shelves with binders. The scene cuts to a person in a white shirt with red stains standing between two police officers in dark blue uniforms; one officer, wearing blue gloves, examines the person’s hand while the other officer stands nearby. The background shows a store interior with shelves and signage. The camera transitions between the two scenes without visible movement.

Discrete solid objects include two police officers and a person in a white shirt. The officers are engaged in a physical interaction (e.g., one officer bends down, hand movements), indicating locomotion and force-based motion.

Background elements (wooden paneling, wall with posters) show no significant shifting or fluid motion (e.g., no fire, water, or wind-driven movement).


A person wearing a dark shirt and light pants plays a brown ukulele, their right hand strumming the strings while the left hand adjusts frets on the neck. The ukulele is held vertically in front of their body. Background elements include a faint red object and a backpack, remaining out of focus. The camera maintains a close-up, steady shot with slight movement, emphasizing the hand motions and instrument.

The hands of the musician are moving to play the ukulele (strumming and fretting), causing motion in the solid objects (hands and ukulele).

Background elements (wall and backpack) are static; no fluid or environmental motion (e.g., fire, water, smoke) observed.


A woman with long red hair and a dark green top reaches for a cluster of pink flowers in front of a glass vase filled with colorful blooms (pink, orange, purple, green). She lifts the pink flowers toward the camera, examining them closely. The vase sits on a surface with additional floral arrangements and decorative items in the background. The camera remains steady and focused on the woman’s hands and the flowers throughout.

The woman's hands are moving to adjust the flowers in the vase, and she is holding a small bouquet of flowers. The flowers are being manipulated by the hands but are not moving independently.

The background (wall, framed picture) is static and shows no shifting. No fire, water, smoke, or wind-driven motion is present.


A red tractor, driven by a person in a white shirt, slowly pulls a blue trailer with a tilted, colorful cargo bed across muddy terrain. The tractor advances forward, and the camera pans slightly to the right to follow its motion, with a distant green field and sparse trees in the background.

The tractor and its attached trailer are moving forward on the muddy ground, with the tractor providing the locomotion.

The background (field and distant trees) is static with no fluid motion (fire, water, smoke, or wind).


A person wearing a maroon jacket with red lining sits at a desk, holding a newspaper. They lift the newspaper toward their face, then lower it and turn a page. The camera remains static, capturing the individual's actions against a backdrop of a brick wall and colored panels.

A person in a pink suit is moving their hands and holding a newspaper, which is being lifted, held to the face, and then placed down on a surface.

Static brick wall and red wall in the background; no shifting or fluid motion (fire, water, smoke, wind) detected.


A female dancer in a blue patterned skirt and dark top performs center stage, initially extending her arms before spinning rapidly with her skirt flaring outward as she moves across the floor. The camera starts with a wide shot, then zooms in to follow her dynamic spinning motion, maintaining focus on her movements against the stage backdrop.

A single dancer (solid, distinct object) performs belly dance movements, including spinning, arm gestures, and hip motions. The dancer is the primary moving entity.

The stage backdrop features fire-like effects, but these are static set design elements rather than dynamic environmental motion (e.g., burning, smoke billowing). No significant fluid or gaseous motion dominates the scene.


A man wearing a blue tank top with visible arm tattoos sits at a table, stirring food in a blue plate with a fork. To his right is another blue plate with food, an orange cup with a lemon slice sits in front of him, and a black knife rests on the table. The background features a plaid couch and a doorway. The camera remains stationary with minimal movement.

The man is moving his arms and hands while eating, which is discrete solid object motion due to his own locomotion.

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


A top-down view shows a person in a beige jacket and blue jeans standing beside a wooden beehive on grass. A hand in a brown glove lifts a honeycomb frame from the hive, revealing bees and honey on its mesh surface. The frame is raised, displaying the bees as the hand holds it steady, while the person remains stationary nearby. The camera maintains a steady top-down perspective, slightly shifting as the frame is lifted.

A dog is actively licking honey from a wooden crate, with its head moving as it interacts with the honey. The person's hand pouring honey is also a discrete object.

The background consists of static grass and a person standing; no significant fluid motion (e.g., fire, water) dominates, and background elements show minimal shifting.


A pair of hairy hands, one adorned with a ring, manipulate copper wires connected to a metallic component. The left hand stabilizes the component while the right hand uses a tool to adjust the wires, with both hands positioned over a table holding papers and tools. The camera maintains a static close-up, top-down perspective throughout.

Hands manipulating copper wires and a connector, with discrete movement as they twist, adjust, and connect components.

The desk, papers, calculator, and ruler remain static with no uniform shifting or fluid motion; no fire, water, or smoke visible.


A woman in a pink shirt with a white collar speaks while seated, with a framed photograph and decorative items visible on a table behind her. The scene transitions to a control room where two individuals—one in a light blue shirt, the other in black—adjust a mixing console; a computer screen displays visuals. The camera cuts from a medium shot of the woman to a medium shot of the control room workers.

Moving discrete objects: a woman speaking in the first scene and two people in the control room (one gesturing, both looking at the screen).

No shifting backgrounds or fluid/environmental motion (fire, water, wind) observed in either scene. Backgrounds (walls, furniture, window) are static.


A boy wearing a gray shirt sits in front of a tall golden harp, his hands moving over the strings as he plays from a music stand. The background features a piano and a decorative fan, with the camera remaining stationary throughout.

The person seated at the piano is moving their head and hands, likely writing or drawing on paper. This is a discrete, solid object motion.

No shifting backgrounds or fluid/environmental motion (fire, water, wind) observed. The room appears static with fixed furniture (harp, piano, walls).


A man in a blue shirt, dark shorts, cap, and sunglasses climbs a tall white ladder, ascending steadily while gripping the rungs and shifting his weight. A firefighter in yellow gear and helmet stands to the left of the ladder, observing. The scene takes place outdoors near a building with trees and a fire hydrant in the background. The camera follows the climber’s upward motion with slight shake.

The person in blue shirt climbing the ladder is moving upward. The person in yellow shirt is standing relatively still.

Background elements (buildings, trees) are stable with no dominant fluid or environmental motion (fire, water, smoke, wind). The slight tree sway is minimal and not dominant.


A hand reaches into the frame and lifts a green square tea bag from a clear glass of green tea, then places the tea bag into a small white bowl positioned to the left of the glass. The smartphone displaying a timer is visible in the lower right corner, counting down from 01:23 to 01:35. The camera maintains a static top-down view throughout, with minimal background elements visible except for the tea boxes and pink flowers.

A hand is moving discrete objects: picking up a chocolate bar, breaking it, adding pieces to a glass bowl, and stirring the mixture. The hand also moves the bowl.

The background (table, boxes, flowers) is static. No fluid motion (like water, smoke) is dominant; the liquid in the bowl is stirred by the hand and is not flowing on its own.


RAW CAPTION: Got it, let's break down the video. The main subject is a marching band. They're in a line, moving across a paved area. The band members are dressed in dark uniforms, maybe black, with some white elements like maybe the instruments or parts of their outfits. The instruments visible are brass, like tubas and trumpets, so they're in a formation. There are several people, maybe 20 or so, marching in a group.

Looking at the movement: they start from the left side of the frame, moving towards the right. As they march, they're in a line, so the formation is straight. The background has some trees, a brick building, and a few cones on the ground. The camera is stationary, maybe from a low angle, since we can see people's heads in the foreground on the left and right, so the camera is probably at eye level of the audience.

Chronic order: The band is marching in a line across the open area. They start in the distance, move towards the camera's perspective (or maybe towards the right side of the frame), and as they move, the camera stays fixed. The people in the foreground are spectators, but the main focus is the band. The spatial relationship: the band is in the middle of the frame, moving from left to right. The background has buildings and trees, but that's minimal.

Now, condense this into a concise paragraph. Make sure to mention motion (marching), appearance (dark uniforms, brass instruments), number (group of musicians), spatial (moving across open area), and camera perspective (stationary, low angle maybe).

Wait, the rules say: focus on motion and behavior in chronological order. So start with the band's initial position, then their movement.

Also, check the output format: must be a paragraph, not bullet points. Keep it concise.

Let me draft:

A group of musicians in dark uniforms with brass instruments marches in a straight line across an open paved area. They move from the left side of the frame toward the right, maintaining a tight formation. The band members, numbering around twenty, are positioned in front of a backdrop of trees and a brick building. The camera remains stationary, capturing the scene from a low angle with spectators partially visible in the foreground.

Wait, but need to check if the number is accurate. The video shows a marching band, maybe 20, but the exact number isn't clear. Maybe just "a group" or "multiple musicians". Also, the rules say "briefly describe their appearance and number (color, size, orientation)". So "dark uniforms" for color, maybe size is not specified, so just "uniforms". Orientation: marching in a line, moving forward.

Also, the camera perspective: the video shows the band from a position where the viewer is behind or at the side, with people's heads in the foreground. So "the camera is positioned behind the band, capturing their movement across the area with spectators partially visible in the foreground".

Wait, the first frame shows the band in the middle distance, and as it progresses, they move towards the camera? Or is the camera stationary and the band moves across the frame.

Looking at the frames: the band is initially in the center, then moves towards the right side of the frame. So the camera is stationary, and the band marches from left to right across the frame.

So the caption should say the band marches from left to right.

Let me try again:

A marching band of musicians in dark uniforms and brass instruments moves in a straight line from the left to the right across a paved area. Approximately twenty band members maintain a tight formation, advancing toward the camera’s perspective. In the background, trees and a brick building are visible, while spectators’ heads appear in the foreground. The camera remains stationary, capturing the scene from a fixed position with minimal movement.

But need to be concise. Let's check the rules: "concise, chronological paragraph".

So chronological order: The band starts in the frame (left side), marches towards the right (moving across the frame), as they move, they get closer to the camera? Or the camera is static, so their position changes.

Wait, the video's frames show the band moving from left to right. So first frame: band is on the left side of the frame, then in subsequent frames, they move rightward, approaching the camera's position.

So the caption should describe the sequence: band members march in a line across the paved area, moving from left to right, passing in front of the camera (or the camera's viewpoint), with the band members' dark uniforms and brass instruments visible.

Also, the camera perspective: "the camera is stationary, capturing the band's movement across the frame".

Putting it all together:

A group of musicians in dark uniforms and brass instruments marches in a straight line across a paved open area

A marching band (multiple individuals) moving in formation across an open area, exhibiting coordinated locomotion.

Background elements (trees, buildings) show minimal uniform shifting; no fire, water, smoke, or wind-driven motion observed.


RAW CAPTION: Okay, let's tackle this video caption request. The user wants a concise chronological paragraph focusing on motion and behavior. First, I need to watch the video description.

The video shows a person in a pink shirt with headphones, standing in front of a green chalkboard and stacked books. The books have labels like Geografia, Matemáticas, Biologia, Fisica, etc. The person starts with arms up, then spreads arms wide, moves hands to head, and ends by turning to the right.

Rule a) says focus on motion chronologically. So, the sequence is: arms up, arms spread, hands to head, turn right. Need to describe each action step by step.

Rule b) mention appearance and number. The person is wearing a pink shirt, headphones. Only one person. Color and size: pink shirt, maybe medium size.

Rule c) spatial relationships. The person is in front of the chalkboard and books. The books are stacked, books are behind them.

Rule d) camera perspective. The description says the video is static, but the user says "conclude with camera perspective and movement". Wait, in the video example, the camera is static? The user says "DO NOT include any reasoning in the caption tags" but the output should be a paragraph.

Wait, the example output given in the instructions is: <caption_output>...<caption_output>

Need to follow the format strictly. The user says "Keep background descriptions minimal unless essential for understanding motion." The background has chalkboard with math problems and books, but maybe the books are part of the background that's static. But the main motion is the person's actions.

So, the caption should describe the person's movements in order, mention their pink shirt, headphones, and maybe the chalkboard and books as background elements without details (since minimal background).

Let me structure it:

The person in a pink shirt and headphones starts with arms raised, then spreads arms wide, raises hands to head, then turns right. Background has chalkboard and stacked books. Camera is static.

Check the rules again. Exclude text recognition (so don't mention Geografia, Matemáticas etc.), but the books are part of the background. Wait, the instruction says "Exclude text recognition, named characters, or stylistic analysis." So the labels on books should be omitted. So just mention stacked books.

So, "a person in a pink shirt and headphones moves their arms up and out, then raises hands to their head before turning right. The person stands in front of a green chalkboard and a stack of books. The camera remains static."

Wait, the exact sequence:

At [0.0], arms raised high. [0.1], arms spread wide. [0.2], hands raised to head. [0.3], hands near head. [0.4], turning to the right. [0.5], continuing turn.

The caption should be chronological. Let's put it all in a sentence.

"The person in a pink shirt and headphones starts with arms raised high, then spreads arms wide to the sides, raises hands to their head, and turns right while maintaining a static camera perspective."

Wait, maybe "arms raised high" then "spreads arms wide", then "raises hands to head", then "turns right".

But need to check the time points. The video has 5 seconds, each frame is 0.5s.

Looking at the frames:

[0.0] arms up high (both)

[0.1] arms still up, but maybe slightly lower?

[0.2] arms wide

[0.3] arms still wide, but maybe hands moved up?

[0.4] hands to head

[0.5] turn right.

Wait, the description says:

Frame 0: arms up high

Frame 1: arms up high

Frame 2: arms wide

Frame 3: arms wide, hands to head?

Wait, maybe the sequence is:

Starts with arms raised high, then spreads arms wide, then raises hands to head, then turns right.

The exact motion:

"arms up, then arms spread wide, then hands to head, then turning to the right."

So the caption should be:

A person in a pink shirt and headphones raises both arms upward, then spreads them wide to the sides, raises hands to their head, and turns to the right. The individual stands in front of a green chalkboard and a stack of books. The camera remains static.

But need to check rules. Rule g says "Think internally, but DO NOT output your reasoning."

Wait, but the user provided the example:

The output should be a paragraph. Let me check the example in the problem statement. The user says "generate a concise, chronological paragraph".

So, in the caption_output, it's a paragraph.

Wait, the sample output format is:

<

A person in a pink shirt is moving their arms and head, demonstrating explicit physical locomotion (raising arms, head movements, and hand-to-face motion).

No shifting background elements observed; chalkboard and book stack remain fixed. No fire, water, smoke, or wind present in the scene.


A boy in a blue shirt and jeans runs forward across the sandy ground, moving away from the frame, followed by a smaller girl in a pink shirt and gray pants who stands in the center of drawn square shapes on the sand. The girl remains stationary as the boy exits the scene. The camera captures a top-down perspective with subtle movement throughout the sequence.

Two children (solid objects) exhibit distinct motion: the child in blue clothing kneels, stands, and moves across the ground, while the child in pink clothing walks away, sits, and then stands again. These actions are due to intentional locomotion and minor falls.

The paved ground background shows minimal shadow movement from the sun, but no fluid motion (fire, water, smoke) or significant wind effects. Static elements like the ground remain consistent without uniform shifting.


RAW CAPTION: Got it, let's break this down. First, the video starts in a dark room. There's a person in the background near a doorway. They're holding a light-colored garment, maybe a shirt, and moving. Wait, the video is dark initially. Then, in the second part, the scene shifts to a brighter room. Let's check the timestamps.

At [0.0], it's dark. A person is by the doorway, possibly entering or moving. Then, at [1.4], they're still near the doorway. [2.5] maybe they're turning around? Wait, the user says the video has frames up to [5.0]. The transition from dark to light happens around the middle.

First part: dark room. Two people? Wait, the description says "a person" in the initial frames. Let's see. The first frame: dark room, person in doorway. Then, moving. Then, the camera might pan to reveal a brighter room. Wait, the [4.7] frame says "the camera pans to a brighter room". So the sequence is: dark room with a person near the doorway (maybe two people?), then the camera moves to show another room with a person in bed or something.

Wait, let's parse each frame:

[0.0] - dark room, person near doorway (holding something, maybe a shirt, since it's a light color).

[1.4] - same dark room, person moving towards the center.

[2.5] - person still in dark room, moving.

[3.6] - camera starts to pan left? Wait, the user's description says at [4.7] it's a brighter room. So the camera motion: from dark room to bright room, panning left.

In the bright room, there's a person in bed or on a couch, covering themselves, maybe moving.

So chronological order:

1. Initial dark room: a person (light-colored clothing) near the doorway. They move towards the center of the dark room.

2. Then, the camera pans to a brighter room. In this room, another person is in bed or on a couch, covered with a blanket, moving (maybe adjusting position).

Now, need to describe appearance: the first person in dark room: light shirt, dark pants (maybe). The second person in bright room: light-colored blanket, dark top (since they're covering), maybe in bed.

Spatial relationships: first person starts near the doorway, moves left. Then camera pans to the brighter room where the second person is lying on the bed.

Camera movement: starts static, then pans left to reveal the brighter room.

Wait, the video starts dark, then the camera shifts to a brighter room. So the transition is a pan.

Also, check the number of people: first scene, maybe one person. Second scene, maybe one person (or two? The description says "a person" in the bright room).

Wait, the frame [4.7] says "a person in bed, covered with a blanket, moving".

So main subjects: two people? First in dark room, second in bright room.

Chronological order:

- The video begins with a dimly lit room where a person wearing light-colored clothing near a doorway moves into the room.

- The camera then pans left to a brighter room, where another person is lying on a bed, covered with a blanket, and adjusts their position.

Wait, the caption needs to be concise, chronological.

Check rules: focus on motion and behavior in chronological order. Mention appearance (color, size, orientation) briefly. Spatial relationships if relevant. Conclude with camera perspective and movement.

Let's draft:

In a dark room, a person in light-colored clothing near a doorway moves toward the center. The camera pans left to reveal a brighter room where a person lies on a bed, covered by a blanket, adjusting their position.

Check for:

- Main subjects: two people. First in dark room (light shirt), second in bright room (bed, blanket).

- Motion: first person moves, then camera pan to second person moving on bed.

- Spatial: first person near doorway (left of the doorway?), camera pans left to show the bright room.

- Camera: starts with static dark room, then pans left to bright room.

Background: minimal. The dark room has a doorway, the bright room has a bed.

Avoid text recognition, named characters.

Now, check length and conciseness.

Possible caption:

A person in light clothing stands near a dark room's doorway, moving leftward. The camera then pans left to a brighter room where another person lies on a bed, covered with a blanket, shifting position.

Wait, does the first person move leftward? The frames show movement towards the center. Maybe "moves into the room".

Alternatively:

In

Two people in the first scene (one moving in foreground, one in background) and one person in the second scene (interacting with items on the floor). All movements are locomotion of discrete solid objects.

The background in both scenes (whiteboard/picture in first, wall/ceiling in second) is static with no uniform shifting. No dominant fire, water, or wind motion observed. The transition between scenes is a cut, not camera motion.


A man in a black shirt with a shoulder strap descends an escalator, steps off, and walks forward while moving away from the camera. The camera follows closely behind with slight shake, capturing the man passing a mesh barrier.

The man (solid object) moves by walking and throwing a ball. The ball (solid object) moves through the air due to the throw, collides with targets, and bounces. Both motions are driven by explicit physical forces (muscle movement, gravity, collision).

Static background elements (metal framework, signs, and structural barriers) show no uniform shifting or fluid motion. No fire, water, smoke, or wind is present as dominant motion.


A person with a black-and-white checkered sleeve and a bracelet on their right wrist holds a spray can, spraying a substance onto a piece of paper inside an open box. The paper, partially visible with red markings, rests on a brown surface with a green checkered pattern to the right. The person’s left hand, adorned with a ring, remains stationary on the box initially, then adjusts the paper after spraying. The camera maintains a top-down perspective throughout, capturing the spraying motion and subsequent hand movements with minimal background details.

Discrete solid objects in motion: Left hand (wearing bracelet) moving to place patterned sheet over paper; Right hand (checkered sleeve) manipulating pen to draw on paper. All motions are deliberate, contact-based actions involving physical force.

No shifting backgrounds or fluid/environmental motion (fire, water, wind) detected. Background elements (table surface, brown paneling, patterned paper) remain static throughout the clip.


RAW CAPTION: Got it, let's see. The video starts with a person bending over, maybe adjusting something. Then they sit down on the grass. There's another person sitting nearby, maybe holding something. The main person is wearing a light-colored shirt and shorts, white socks. The background has a car and some items on the grass. Let's track the actions chronologically.

First frame: person bends over, maybe picking up or adjusting. Then sits down. Then stands up? Wait, the sequence: [0.0] person bent over, [1.4] still bent, [2.5] sitting on grass, [3.6] sitting, then [4.7] the person is lying down? Wait no, the description says [4.7] "the person is lying down" but in the video, let's check.

Wait the user provided the frames:

Frame 0: person bending over, hands on knees, grass, car, others.

Frame 1: same person bending, more upright.

Frame 2: person bending, others sitting, grass, car, items.

Frame 3: person sits down on grass, others are there.

Frame 4: person lying down on grass.

Frame 5: person is now standing? Wait no, the frame 4.7 is "the person is lying down" but the description says "the person lies on the grass" in frame 4. Then frame 5 is the person sitting up.

Wait, let's read the user's input:

<0.3 seconds> [person bending]

<1.4> [still bending]

<2.5> [sitting]

<3.6> [lying down]

<4.7> [sitting up?] Wait no, the user's description:

Frame 0: [0.3] person bending, others sitting.

Frame 1: [1.4] person still bending, others.

Frame 2: [2.5] person bending, others, items on grass.

Frame 3: [3.6] person sits down on grass (sitting with legs spread, maybe), others.

Frame 4: [4.7] person is lying down on grass (the description says "the person lies on the grass").

Wait, the user's video frames:

At 0.3s: person bends over, hands on knees, grass, car, others.

1.4s: same person still bending, maybe adjusting.

2.5s: person bends over, others sitting, items on grass.

3.6s: person sits on grass, legs apart, others.

4.7s: person is lying on grass (the caption says "the person lies on the grass").

So chronological order: person starts bending (maybe picking up a book or something), then sits down, then lies on the grass.

Wait, the action: in 0.3s, the person is bending over. Then in 2.5s, they are sitting on the grass. Then in 4.7s, they are lying on the grass.

Wait the video sequence:

Frame 0 (0.3s): person is bending over, hands on knees, others sitting nearby.

Frame 1 (1.4s): person still bending, perhaps adjusting.

Frame 2 (2.5s): person bends over, others are sitting, grass, car, items.

Frame 3 (3.6s): person sits on grass, legs stretched out, others nearby.

Frame 4 (4.7s): person lies on grass, maybe after sitting.

Wait, maybe the person starts bending, then sits, then lies down. Let's outline the actions:

- A person wearing a light shirt and dark shorts, white socks, bends over while others sit on grass.

- They then sit down on the grass.

- Then lie down on the grass.

Wait, the frames:

0.3: bending

1.4: bending (slight movement)

2.5: bending (still)

3.6: sitting on grass

4.7: lying on grass

So motion: bending → sitting → lying down.

Now, main subjects: two people? One person doing the action, another sitting. The person in question is wearing a light-colored shirt, dark shorts, white socks. The other person is sitting, maybe holding a book or something.

Background: grass, a silver car, some items on grass (like a red and white object, maybe a toy or book).

Spatial relationships: the person is in front of the car, others are sitting nearby.

Camera: maybe handheld, slight shake. The camera moves to follow the action.

Now, following the rules:

Focus on motion and behavior chronologically. Briefly describe appearance and number. Mention spatial relationships if relevant. Conclude with camera perspective.

So:

A person wearing a

A man in a gray shirt bends, sits, and lies down on the grass; other individuals sit nearby, handling objects (e.g., a book/tablet). All movements are deliberate physical actions by solid objects (people).

The background includes a stationary silver car and grass, with no shifting or fluid environmental motion (e.g., fire, water, smoke, wind).


A person wearing dark clothing sits on a green chair, playing a sunburst-colored bass guitar with a white pickguard. Their left hand frets notes on the neck while the right hand strums the strings. The camera remains static with a slight shake, focusing on the upper body and instrument against a blue floor and white wall.

Discrete solid object: Person playing bass guitar. Hands and arms move due to explicit physical forces (fingering fretboard, strumming) while body remains seated.

Background elements (wall, floor) are static and show no uniform shifting or motion. No fluid/environmental motion (fire, water, smoke, wind) is present.


In the opening scene, multiple individuals sit and stand on colorful mats inside a room with wooden paneling, some performing seated stretches. The scene transitions to a larger group on mats, where people in various colored athletic wear (e.g., black, red, blue) sit cross-legged or adjust their positions, with one person in a black leotard extending her leg. Finally, a close-up shows two individuals conversing—one in a red top and another in a light blue shirt—while seated on a mat. The camera shifts between group shots and a close-up, with minimal background details.

People are moving by sitting, stretching, and bending.

The background (walls, radiator, bed) is stationary and does not show uniform shifting. No fire, water, smoke, or wind is present.


A person in a blue shirt slices a small striped watermelon on a wooden table, while another individual in a dark shirt and light pants holds a container near the table. The watermelon is cut into two halves, which are then placed on the table; the person in blue adjusts the pieces. The background features flowering plants and greenery. The camera shifts to capture the split watermelon and surrounding garden elements with slight movement.

A person's hands and a knife interact with a watermelon, cutting it into pieces. The watermelon segments and the person's movements are discrete solid objects undergoing physical cutting motions.

The background elements (flowers, foliage, wooden structure) are static and show no uniform shifting or fluid motion. No fire, water, or smoke is visible.


A hand stirs a crumbly, light brown mixture in a clear glass bowl with a metal spoon. Then, the hand uses the spoon to scoop portions of the mixture and places them onto a baking tray lined with white parchment paper, arranging the portions into neat rows. The camera maintains a top-down view throughout the process.

Hand and spoon are moving to stir and scoop cookie dough. Cookie dough balls are being formed and placed on the baking sheet.

No shifting background or fluid/environmental motion observed. Background elements (countertop, baking sheet) are static and consistent throughout the clip.


A hand manipulates colorful beads (purple, orange, blue, green) on a thin thread, positioning a bead on one strand before threading a star-shaped object over both strands. The hand moves the thread and beads with precise motions, focusing on the beadwork process. Camera remains close-up, slightly shaky, tracking the hand's actions.

A hand manipulates a needle and beads, with discrete objects (hand, needle, beads) moving due to manual threading actions.

Background consists of static colorful beads and neutral surface with no visible fluid motion (fire, water, smoke) or uniform background shifts indicating camera movement.


A person wearing red and black gloves kneels on a wooden floor, using a tool to work along the baseboard. They adjust their position, moving the tool across the floorboards near the wall, then shift to work closer to the baseboard. The camera maintains a low, static perspective focused on the floor and the person’s hands.

A person wearing red gloves and blue jeans is moving their hands and body while working on the wooden floor; discrete locomotion of the person's limbs and torso is visible.

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


A man in a navy blue sweater with a red collar smiles toward the camera, surrounded by several people including a woman in a gray hoodie and white skirt holding a green cup, and a person in a maroon shirt. The man turns his head slightly as the scene progresses, then a woman with pink sleeves approaches from the right and places a white card over his eyes. The camera remains steady with minor movement during the card placement.

Discrete solid objects in motion include the person in the blue sweater (head movements) and the individual in pink (arm motion to position a card near the subject’s face). These movements result from physical interactions and explicit actions.

Background elements (e.g., people, structures) show no uniform shifting or fluid environmental motion (fire, water, smoke, wind). No dominant fluid dynamics observed.


A woman in a red traditional outfit dances on a red carpet in a banquet hall, moving her arms and legs fluidly. She begins with arms extended, then raises one arm high as she spins, continuing her performance while guests seated at white-clothed tables observe. A man in a black suit stands to her left, and others watch from the sides. The camera follows her movements with slight panning.

The main moving object is the dancer in red (a person) moving across the stage by locomotion (dancing). Other objects (seated people) are stationary.

The background (walls, curtains, seated people) is fixed and shows no shifting. No environmental fluids (fire, water, smoke, wind) are present.


A shirtless person in a light-colored swimsuit lies prone on a white water slide, sliding headfirst downward. They flip in midair before entering a pool with a splash, landing in the water. The camera follows their descent from a slightly elevated angle, exhibiting a slight shake.

A person slides down a water slide, transitioning from the slide into the pool. The motion is due to gravity and the slide's structure, with the person being the clear discrete object in motion.

The background elements (slide structure, pool deck, umbrellas) remain stable and do not exhibit fluid motion. Water in the pool is present but not dominant; splashing is incidental to the object's movement.


A person in a green shirt and dark pants performs pull-ups on a horizontal bar in a gym, lifting their body upward and then lowering it while maintaining a grip. The individual remains positioned centrally in front of the bar, with gym equipment visible to the left and right. The camera maintains a fixed perspective from behind the subject throughout the sequence.

A person in a green shirt and dark pants is performing pull-ups on parallel bars, moving their body up and down due to muscular force.

The gym background (walls, equipment, clock) shows no shifting or fluid motion. No fire, water, smoke, or wind is visible.


A person in a black shirt and blue pants lies on a mechanical lift beneath a vehicle, holding a white container. They raise their right hand to adjust a component under the vehicle, then lower it to pick up a cloth, wiping the area. The camera remains stationary, positioned directly under the vehicle, capturing the person's actions from a low angle.

RAW CAPTION: Got it, let's tackle this captioning task. First, I need to understand the video sequence. The video starts with a close-up of a black machine, which looks like a nut roaster or coffee roaster, filled with yellow nuts (maybe peanuts) inside a transparent chamber. The background has a wooden wall and gravel. Then, the machine is shown with some steam or smoke, indicating it's heating up. Next, a hand appears, pressing a red button on the side of the machine.

Now, following the rules: focus on motion and behavior in chronological order. Main subject is the machine and the hand. Describe appearance: machine is black, transparent chamber with yellow nuts. Hand is a person's hand (skin tone, size). Spatial relationships: hand is approaching the machine, pressing the button. Background is minimal, so maybe just mention the gravel and wooden wall briefly. Camera movement: starts close-up, then shifts to show the hand pressing the button.

Check rules: exclude text recognition, so no "RED" or other labels, but the button is red. Wait, the problem says "exclude text recognition" but the button is red, so maybe describe as "red button" without text. Wait, the example in rules says "exclude named characters or stylistic analysis," so the color of the button is part of appearance.

Chronological order:

1. Close-up of black machine with transparent chamber filled with yellow nuts.
2. Machine shows activity (maybe smoke) as it operates.
3. A hand presses a red button on the machine's side.

Camera perspective: starts with close-up, then shifts to a closer view of the hand pressing the button.

Now, structure the caption:

Start with the machine's state: "A black electric machine with a transparent chamber containing yellow nuts is shown in a close-up. The machine emits steam as it operates. A hand with a light skin tone presses a red button on the machine's side, activating it."

Check if it's concise. Remove redundant parts. Maybe:

"A black electric roasting device with a transparent chamber filled with yellow nuts sits on a gravel surface against a wooden wall. The device emits steam as it heats, and a hand presses a red button on its side to activate it."

Wait, background is gravel and wooden wall. The rule says "background descriptions minimal unless essential for understanding motion." Is the background essential? Maybe not, but the machine's position relative to background (gravel, wooden wall) is part of the scene. But maybe keep it minimal.

Wait, the first frame shows the machine, then the machine's operation (steam), then the hand pressing the button.

So chronological:

1. Close-up of black machine with yellow nuts in transparent chamber.
2. Machine shows steam or activity.
3. Hand appears, presses red button.

So caption: A black electric device with a transparent chamber filled with yellow nuts is shown. As it operates, steam rises from the chamber. A hand presses a red button on the device's side.

But need to mention spatial relationships. The hand is approaching the device.

Also, the device is placed on a gravel surface, but background is minimal. Maybe mention "on a gravel surface" as part of the setting.

Wait, the rules say "keep background descriptions minimal unless essential for understanding motion." So if the gravel is just part of the scene, maybe not necessary, but the wooden wall in the background is also there. But perhaps it's better to focus on the main subjects.

Main subjects: machine, hand.

Machine: black, transparent chamber with yellow nuts (maybe peanuts), emitting steam. Hand: light-skinned, presses red button on the machine's side.

Chronological:

- First frame: machine with nuts inside, close-up.
- Second frame: machine still, maybe steam.
- Third frame: hand pressing button.

So:

"A black electric roaster with a transparent chamber filled with yellow nuts sits stationary. The device emits steam, and a light-skinned hand presses a red button on its side to initiate operation."

Check if it's concise. Let's see:

"A black electric roaster filled with yellow nuts in a transparent chamber emits steam. A light-skinned hand presses a red button on the roaster’s side."

But need to mention the chronological order. The sequence is: machine with nuts, then steam, then hand pressing button.

So:

"A black electric roaster with a transparent chamber containing yellow nuts is shown. The roaster emits steam as it operates. A light-skinned hand presses a red button on the roaster’s side to activate it."

That covers the motion: machine first, then steam (activity), then hand pressing button. Appearance: black machine, yellow nuts, red button. Spatial: hand is on the side of the machine.

Camera perspective: starts with close-up of the machine, then shifts to show the hand pressing the button. So camera

RAW CAPTION: Got it, let's tackle this. First, I need to describe the video chronologically. The main subjects are a group of people dancing. Let's check the frames.

Frame 0: Several people in a room, some standing, some moving. They're in a circle or group. Let's count—there are about 7 people. They have different outfits: some shorts, some pants, tank tops, t-shirts. One person is in a black top and gray pants, another in a green shirt and red shorts, etc. They start by raising hands.

Frame 1: More people join or move. The group is dynamic, some arm movements. The camera seems to pan left a bit. The people are dancing, arms raised, some stepping.

Frame 2: The group is more spread out, still dancing. The camera moves left. The room has chairs and a drum on the floor. People are moving around, some with arms up.

Frame 3: The camera shifts, maybe pans left again. More people are visible. One person in a blue shirt and silver shorts. The group continues dancing, arms moving. The lighting might change (like a pink tint in later frames? Wait, the video has a frame where it's pink, but maybe that's a filter. Wait, the last frame has a pink hue, but the main motion is the group dancing.

Now, chronologically: The group of people (approximately 7-8) in a room with chairs and a small drum start dancing. They begin with arm movements, raising hands and arms above their heads. As the video progresses, they move around the room, some stepping forward or backward, continuing synchronized dance moves. The camera pans left, capturing the group's motion from a slightly elevated perspective, with the room's background (walls, chairs) visible but minimal. The people's attire includes various casual clothing like shorts, t-shirts, and pants, in different colors. The camera remains steady but shifts perspective to follow the dancers, with a slight shake as it moves.

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

- Start: Group of people (7-8) in a room, dancing. They raise arms, some step.

- Progress: They move, arms up, dance in formation.

- Camera: Pans left, captures their motion; background has chairs, small drum.

- End: The scene shows them continuing, with camera movement.

Need to keep it chronological, focus on motion, appearance (number, clothes), spatial (group moving, room elements), camera.

Let me check rules:

a) Motion chronologically: start with initial dance move (arms up), then moving around, continuing dance.

b) Appearance: number (approx 7-8), clothes (various: shorts, pants, t-shirts, etc.)

c) Spatial: group in room, chairs in background, drum on floor. They are in front of chairs, moving around.

d) Camera: pans left, slight shake, elevated perspective (since the view is from above maybe? Wait, the video is a bit low angle? The first frame shows people from a bit low, but maybe "slight shake" as it's a handheld camera).

e) Background minimal: chairs, drum, walls.

f) Exclude text, names.

So draft:

A group of approximately seven to eight people in casual attire (shorts, t-shirts, pants) perform synchronized dance movements in a room with chairs and a small drum on the floor. Initially, they raise their arms upward, then move in a circle while stepping and gesturing. The camera pans left across the room, maintaining a slightly elevated perspective with a subtle shake, capturing their continuous motion against the minimal background of walls and furniture.

Check if it's concise, chronological. Yes: initial action (arms up), then moving in circle, camera pans left. Mentioned number, appearance (casual, colors), spatial (room, chairs, drum), camera movement (pans left, elevated, shake). Background minimal.

Wait, the last frame has a pink tint, but rule f says exclude stylistic analysis, so maybe not mention the color change. Focus on motion.

Let me refine:

In a room with chairs and a small drum, a group of seven to eight people in casual clothing begin synchronized dance movements, raising their arms. As they dance, they shift positions, stepping and moving in a circle. The camera pans left while slightly shaking, capturing their motion from a slightly elevated angle.

Wait, "begin... raising arms" then "shift positions, stepping..." that's chronological.

Yes. Make it concise. Let's write:
