RAW CAPTION: Got it, let's tackle this. The video shows two people practicing sword fighting on a blue mat. First, I need to note their appearance: one in maroon shirt and black shorts, the other in blue shirt with black pants and pink shoes. They're moving around, swinging swords. Let's go chronologically.

In the first frame, the blue-shirted person is raising the sword, maroon is in a stance. Then they switch positions—maroon moves to the left, blue to the right. They're facing each other, swords drawn. The background is a gym with blue mat, wooden panels, window. Camera is stationary, top-down? Wait, the description says "top-down" but in the video, it's a side view. Wait, the problem says "conclude with camera perspective and movement." The video is likely a fixed camera, no movement. So camera is static, probably side view.

Wait, the user's example: "a stationary camera captures a martial arts sparring session between two individuals on a blue mat..." So need to describe their actions step by step.

Let's structure: two individuals, one in maroon shirt and black shorts, the other in blue shirt, black pants, pink shoes. They begin by facing each other, swords drawn. Then they move, switching positions—maroon steps left, blue steps right, both raising swords in a defensive/attacking motion. Their movements are fluid, swinging swords. Background is gym with blue mats and wooden panels. Camera is stationary, side view.

Wait, need to be concise, chronological. Let's check each frame:

[0.0] Blue person raises sword, maroon in stance.

[1.0] Maroon moves left, blue steps back? Wait, frame 1: blue person's sword is extended, maroon is moving to the left. Then frame 2: maroon is left of blue, both holding swords.

Frame 3: maroon raises sword, blue steps back.

Frame 4: maroon swings, blue blocks?

Wait, the user's video: the first frame, blue person (with pink shoes) is holding sword up, maroon (maroon shirt, black shorts, barefoot) is in a forward stance. Then in frame 1, maroon moves to the left, blue steps to the right, both swords extended. Then frame 2, maroon swings sword, blue blocks? Wait, need to watch the motions.

Wait, the key is chronological order. So start: two people, one in maroon top/black shorts, the other in blue top/black pants/pink shoes, engaged in sword practice on a blue mat. Maroon starts with a forward lunge, sword extended toward blue. Blue raises sword in a defensive stance. Then maroon retreats to the left, blue steps right, both swords drawn. Maroon then swings sword in a sweeping motion, blue responds with a similar swing. The two continue their back-and-forth sword movements, maintaining distance. Background features a gym with blue mats and wooden paneling. Camera remains stationary, capturing the action from a side angle.

Wait, but need to keep it concise. Let's see:

Two individuals, one in maroon shirt and black shorts, the other in blue shirt, black pants, and pink shoes, practice sword fencing on a blue mat. Initially, the blue-shirted person raises their sword while the maroon-shirted person lunges forward. They then switch positions, with the maroon-shirted individual stepping left and the blue-shirted person moving right, both extending swords. Subsequently, they alternate swinging their swords in a fluid motion. The camera remains stationary, observing from a side perspective with a gym setting featuring wooden paneling and blue flooring.

Wait, the rules say "briefly describe appearance and number". So mention colors: maroon shirt (male? but gender not specified), blue shirt. Number: two people.

Check the rules:

a) Motion and behavior in chronological order. So:

- Start: blue person raises sword, maroon lunges forward.

- Then: maroon steps left, blue steps right, swords extended.

- Then: maroon swings, blue swings.

b) Appearance: two people, one maroon shirt/black shorts, one blue shirt/black pants/pink shoes.

c) Spatial: blue to the right, maroon to the left? Wait, initial position: blue is on right, maroon on left (since frame 0 shows blue on right). Then in frame 1, maroon moves left, blue moves right? Or they switch sides.

Wait, in frame 0, the person in blue is on the right, maroon on the left. Then frame 1: maroon moves to the left (so even further left?), blue steps right. Wait, maybe it's them moving around each other. The main idea is

Two fencers (discrete solid objects) moving with swords; their motion involves lunging, parrying, and shifting stances due to physical interaction.

Background elements (wooden panels, window, floor) show no uniform shifting; no fire, water, smoke, or wind visible.


A person wearing a white helmet and light-colored clothing rides a Segway along a tree-lined path, moving from left to right between tall palm trees. The scene transitions to the person standing near a railing by the beach, facing the camera with the ocean and sandy shore visible behind them. The camera perspective shifts from a follow shot of the Segway rider to a self-facing view as the person stops at the beach.

A person in a white shirt and blue pants walks from the left toward a small white shed with double doors, opens both doors to reveal the interior, steps out, and walks away. The shed sits on a wooden platform under a large tree, with a ladder positioned to the left of the tree. The camera remains stationary, capturing the scene from a fixed eye-level perspective.

Discrete solid objects (two people) move via locomotion: one person walks from the right to the door, another approaches the door, and both interact with the building entrance (opening the door, entering/exiting). These motions are distinct and trackable with bounding boxes.

Background elements (trees, small building, fence) show no uniform shifting or fluid motion (e.g., no wind-induced swaying, fire, or water flow observed). Static backdrop remains consistent across frames.


A man in a dark shirt, black shorts, white socks, and black shoes begins bent over on a wooden gym floor; he stands upright, takes a step forward with his left foot, and swings his right arm outward. The background features wooden walls and a basketball hoop, with the camera remaining static throughout the sequence.

A person (wearing black attire) is moving through the gym: initially bending over, then standing, and kicking a ball (implied by action). The motion is due to locomotion and kicking.

Background (wooden bleachers and court lines) is static and does not shift. No environmental fluids, fire, water, or wind visible.


A pair of light brown-skinned hands, with fingers visible from a checkered shirt, interact with a metallic circular object featuring concentric ridges. The hands press rhythmically on the surface, moving in a circular pattern across the ridges and occasionally shifting positions. The camera maintains a close-up perspective with slight movement, focusing on the hands’ interaction with the object against an indistinct background.

Hands (discrete objects) press and move across a circular metallic object with concentric ridges, causing it to rotate. The hands apply direct physical force, resulting in distinct motion of the object.

The background (wall and surface) shows no uniform shifting or fluid motion; no fire, water, smoke, or wind is visible. The background remains static throughout the clip.


A person wearing a dark hoodie and glasses holds a purple object with a white, fluffy attachment, moving it from right to left toward their face, then bringing it to their mouth; computer monitors displaying software interfaces and an American flag are visible in the background, with the camera maintaining a close-up perspective and slight shake.

A person holding and consuming an ice cream cone; the cone and the person's hand/arm exhibit discrete solid-object motion due to eating actions.

The background elements (computer monitors, shelves, desk items) remain static with no shifting or fluid motion; no fire, water, or wind is present.


A girl in a black dress stands on the right side of a dirt tennis court, adjusting her stance. A person in a white shirt and dark shorts moves across the court from left to right, then stops. A boy wearing a red cap and dark shirt runs into the frame from the left. The camera remains static throughout, capturing the action from a fixed perspective with minimal background details visible.

Two tennis players (one in dark blue, one in black) and a tennis ball exhibit discrete motion. Players move via locomotion (stepping, running), and the ball moves due to collision with rackets and gravity.

Static background elements (chain-link fence, bleachers, trees) show no shifting or fluid motion. No fire, water, smoke, or wind-driven movement is visible; all environmental components are stationary.


A hand holds a black and silver device on a dark wooden surface, with a red bowl containing whole and sliced tomatoes positioned to the right. A second hand brings a large knife from the right, places it over the device, then withdraws the knife. The first hand shifts leftward. Camera maintains a top-down perspective with no movement.

A hand uses tongs to move tomatoes from a red bowl to a cutting board; the hand, tongs, tomatoes, and bowl are discrete solid objects exhibiting physical motion due to human action.

No shifting background elements observed (black table surface remains static); no fluid/environmental motion (fire, water, smoke, wind) present.


A woman with blonde hair tied back in a ponytail, wearing a black sleeveless top and black shorts, begins seated on a gray platform. She grasps a vertical trapeze bar, pulls herself upward, and rotates her body to face away from the platform. The camera maintains a fixed perspective, capturing her motion against a plain white background.

A person in athletic wear is performing seated exercises on a mechanical apparatus, moving their body (e.g., shifting position, adjusting grip) while interacting with the equipment.

The background is a uniform white with no shifting elements or environmental fluids (fire, water, smoke, wind), so no ambient_environmental motion is present.


RAW CAPTION: Got it, let's tackle this. First, I need to look at the video frames. The first frame shows two people: one in red and black, the other in orange. They're on a swing set, maybe. Then, in the next frames, they swing, and one falls off. Wait, let's check chronologically.

Frame 0: Two people on a swing. The person in red (maybe) is on the left, orange on the right? Wait, the first frame shows them on the swing. Then frame 1: they move, maybe the swing is in motion. Frame 2: the person in red is still, maybe the swing is moving, but the other person (orange) is falling off? Wait, frame 2: the orange person is on the swing, but then in frame 3, the orange person is gone, and the red person is there. Wait, maybe they're swinging, then one person (orange) falls off, and the red person continues. Let's see the sequence.

Frame 0: Both on the swing. Frame 1: They swing, maybe the swing moves. Frame 2: The orange person is still on, but then frame 3: the orange person is gone, red person is on the swing, moving. Then frame 4: swing is moving without the orange person. Wait, maybe the orange person falls off, then the red person continues. Let's check the actions.

Main subjects: two people. First, they are on the swing set. Then the swing moves, and one person (maybe the orange one) falls off the swing. Then the red person continues swinging, but the swing becomes empty. Let's confirm.

First frame: two people on swing. Second frame: swing in motion, maybe they're moving. Third frame: the swing is moving, but one person (orange) is no longer there, red person is there. Then fourth frame: swing is empty, only the swing structure. So the chronology is: two people on a swing, swing moves, one person (orange) falls off, leaving the other person (red) on the swing, who continues moving, and then the swing is empty.

Now, appearance: first person (red), second (orange). Number: two, then one. Spatial: the swing is in front of houses and grass. Background: houses, grass, but minimal. Camera: seems to stay in one place, maybe a slight shake, but the camera perspective is static, looking at the swing from a fixed position.

So the caption should be chronological: two people (one in red, one in orange) on a swing set swing forward, then the orange person falls off, leaving the red person continuing to swing, and the swing structure remains in view.

Wait, let's check the frames again. Frame 0: two on swing. Frame 1: maybe they're moving. Frame 2: the swing is still moving, but the orange person is now on the ground? No, frame 2: the swing is moving, the orange person is still there? Wait, maybe the swing is a rope swing? Or a traditional swing. Wait, the first frame shows two people on the swing, then in frame 1, they move, frame 2, the orange person is still there, then frame 3, the swing is moving, but the orange person is no longer there? Maybe the orange person jumps off or falls. Wait, frame 2: the swing is in motion, the two people are there. Then frame 3: the orange person is gone, red person is on the swing. Then frame 4: swing is empty.

So the action is: two people on a swing (red and orange) swing forward, then the orange person falls off, and the red person continues swinging, eventually leaving the swing empty.

Now, mention the appearance: two individuals, one in red clothing, one in orange. Number changes from two to one to zero.

Spatial relationships: they are in front of a grassy area with houses in the background.

Camera: fixed, no movement, but maybe slight shake? The problem says "conclude with camera perspective and movement". The video might have a slight shake, but the camera is static looking at the swing.

Now, put it all together concisely.

"Two individuals, one in red and one in orange, swing together on a swing set. The orange-clad person falls off the swing, leaving the red-clad person continuing to swing, which eventually empties as the swing moves away from the camera. The camera remains stationary, capturing the motion from a fixed angle with minimal background detail."

Wait, check the rules. Background descriptions minimal unless essential. So maybe "in front of houses and grass" but keep it minimal.

Alternative: "Two people (red and orange) swing on a swing

A person (in red) dribbles and shoots a basketball, with the ball moving due to physical forces (dribbling, shooting, bouncing). The person's locomotion (running) is clearly visible.

Background elements (houses, grass, basketball hoop) remain stable without uniform shifting; subtle grass sway is minor and not dominant. No fire, water, or smoke observed.


In a dimly lit room with wooden flooring and dark walls, a man in a gray shirt and dark pants and a woman in a black top and dark pants dance closely. The woman raises her arm, they turn together, release their hold, and then walk side by side while holding hands. The camera remains stationary throughout, capturing their movements from a fixed perspective.

Two people (a man and a woman) are dancing, moving through coordinated steps, turns, and physical interactions (e.g., lifting and setting down).

Background elements (walls, ceiling lights, panels) are static with no uniform shifting. No environmental motion (fire, water, smoke, wind) is present.


RAW CAPTION: Got it, let's break down the video. First, the main subject is a person with dark hair, wearing a striped shirt. They're in a room with a towel rack and clothes hanging in the background. The person is holding a blue object, maybe a hair tool, and starts moving their hand up, like applying something to their hair. Then the scene cuts to black with text about leaving it on for an hour, but we don't need to mention that text. Next, a different person with teal and purple hair is in a car, drinking from a cup. Wait, the first part: the person in the room, maybe washing or applying dye? The sequence: person in room, moves hand to hair, then black screen with text, then person in car. But the caption should be chronological. Let's structure it.

First scene: A person with dark hair, wearing a striped shirt, is in a room with a towel rack and clothes hanging. They raise their right arm to apply a blue object (maybe hair dye) to their head. Then the video cuts to black with on-screen text. Next, a second person with teal and purple hair is seated in a vehicle, holding a cup to their mouth. The camera is mostly static in each scene, but between scenes there's a cut. Background in first scene: towel rack, clothes. Second scene: interior of a car, window visible. Need to mention motion: first person moving arm, second person drinking. Keep it concise.

Check rules: focus on motion, chronological. First subject: person applying blue item to hair. Then text screen. Then second person drinking. But the text screen is part of the video, but the rules say exclude text recognition. Wait, the text is "left it on for an hour then rinse," but rule f says exclude text recognition, so we don't mention that text. So the video sequence: person applying something to hair, then cut to black (maybe), then person in car. Wait, the first part: [0.0] shows person with hair, [1.4] same person holding blue cloth, moving hand up, [2.5] same, [3.6] black, [4.7] person with colorful hair. So the video has three segments: first, a person in a room with towel rack, using blue cloth on hair; then black screen; then a person in a car with colorful hair.

So the caption should describe the chronological order of events:

- A person with dark hair, wearing a striped shirt, is in a room with a towel rack and clothes hanging in the background. They raise their right arm, holding a blue cloth, and apply it to their head.
- The video cuts to a black screen.
- Then, a person with teal and purple hair is seated in a vehicle, holding a cup to their mouth.

But need to check if the background is essential. The first scene's background: towel rack, clothes are part of the setting, but maybe minimal. The rules say "minimal unless essential for understanding motion." So the towel rack and clothes are part of the room, so maybe necessary to mention context.

Wait, the person is applying the blue cloth to their hair, so the motion is applying. The second scene is the person in car drinking.

So structure:

A person with dark hair, wearing a striped shirt, in a room with a towel rack and hanging clothes, raises their right arm to apply a blue cloth to their head. The scene then cuts to black, followed by a person with teal and purple hair seated in a vehicle, holding a cup to their mouth.

Check for concise: "A person with dark hair, wearing a striped shirt, in a room with a towel rack and hanging clothes, raises their right arm to apply a blue cloth to their head. The video cuts to black, then shows a person with teal and purple hair in a vehicle holding a cup to their mouth."

Wait, the first part: [0.0] shows the person, [1.4] they're holding blue cloth, [2.5] applying. So the motion is applying the cloth to hair. The background: towel rack with clothes. Then black screen, then person in car.

Yes. Now, camera perspective: first scene is close-up on person, then maybe static. Then black screen, then close-up on the second person. But the rules say to describe camera movement at the end. "Conclude with the camera perspective and movement (e.g., top-down, pan left, slight shake)."

In the first scene, it's a close-up shot. The camera doesn't move much; maybe a static shot. Then the black screen, then a close-up of the second person. But the instruction is to describe the overall camera perspective for each segment. Let's see.

First scene: close-up on the person's face and

Briefly describe what discrete, solid objects are moving.

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


RAW CAPTION: Got it, let's tackle this. First, the video starts with a scene in a lecture hall. There's a speaker on stage, and a projection on the screen. The projection shows a group of people outdoors. The speaker is standing at the podium, maybe giving a presentation. Then, the video transitions to a closer view of the stage. The speaker moves slightly, maybe gesturing. The audience is seated, facing the stage. The camera seems to pan from a wider view to a closer one of the stage. Let's check the rules: focus on motion and behavior chronologically. So first, the initial wide shot with speaker and projection. Then the speaker moves. The projection is of a group (but don't mention names or text). The speaker is in front of the screen, near the podium. The camera moves from the first shot to a closer angle of the stage. Let's make sure to describe the motion: the camera pans left slightly to show the stage more clearly. The speaker is in dark clothing, standing at the podium. The group on screen is a mix of people, maybe 6-7, outdoors. Need to keep it concise. Let's structure it: Start with the scene: a lecture hall with a speaker at a podium, projection of a group on screen. Then the speaker moves, the camera pans to a closer view of the stage. No text recognition, so don't mention the "5" sign, just say there's a sign with a number. But rule f says exclude text recognition, so maybe mention "a sign with a number" but not the number. Wait, rule f says "Exclude text recognition, named characters, or stylistic analysis." So we can't describe the text on the sign, just say there's a sign. But maybe the sign is part of the background, minimal background. Let's focus on the main subjects: the speaker. The speaker is a person (gender? Not specified, so just "a person"), standing at the podium. The projection has a group of people. The camera movement: starts with a wide shot, then shifts to a closer angle. The speaker is moving slightly, maybe adjusting position. Let's put it all together.

Chronological order: First, the video shows a lecture hall with a person standing at a podium, presenting in front of a large screen displaying a group photo. The person is positioned to the right of the screen, wearing dark clothing. Then, the camera shifts to a closer view of the stage, where the person moves slightly forward and to the right. The audience is seated in the foreground, facing the stage. Background includes a wooden stage, a sign with a number, and ceiling lights. Camera movement: starts with a wide shot, pans slightly left to focus on the stage and presenter. Keep it concise.

Wait, rule d: conclude with camera perspective and movement. So need to end with that. Let's check the output format: <caption_output>...<caption_output>

Let's draft:

A person in dark clothing stands at a podium on a wooden stage, presenting to an audience seated in rows. A large projection screen behind them displays a group of six people outdoors. The camera pans slightly left, shifting focus to the stage, where the presenter moves slightly forward and adjusts position. The background includes a sign with a number and ceiling lights.

Wait, but the video starts with a wide shot (first frame), then the second frame is a bit closer. The main motion: the presenter is moving, the camera is panning. Let's make sure chronological order. The video begins with the presenter at the podium, screen showing group. Then, the presenter moves slightly. The camera shifts to a closer angle. So first, the scene: lecture hall, presenter at podium, projection. Then presenter's movement. Camera movement from wide to close.

"Beginning with a wide shot of a lecture hall, a person in dark clothing stands at a podium facing an audience, with a large projection screen displaying a group photo of six individuals outdoors. The camera pans slightly left, zooming in on the stage as the presenter moves forward and adjusts their stance."

Check rules: no text recognition (so don't mention the number on the sign, just say a sign). The group on screen: describe as six people outdoors. The presenter's movement: moves forward and adjusts stance. Camera perspective starts as wide, then pans left to zoom in.

Is the sign essential? The rule says minimal background unless essential for understanding motion. The sign is in the background, not essential for motion, so maybe omit it. The rules say "keep background descriptions minimal unless essential". So maybe just mention "audience seated" as background.

Revised: "A person in dark clothing stands at a podium on a wooden stage, presenting to an audience. A large projection screen displays a group of six people outdoors. The camera pans slightly left to focus on the

A person on stage (presenting) exhibits controlled movement (e.g., gesturing, slight walking), with discrete, solid object motion distinguishable from background.

Background elements (stage, curtains, walls) show no uniform shifting; no fire, water, smoke, or wind present, so ambient environmental motion is excluded.


A person in a white T-shirt, blue denim shorts, and orange sneakers pushes a large maroon exercise ball on a pink mat, then lowers into a plank position with hands on the ball and legs extended back, and finally returns to a crouched stance. The camera remains stationary, capturing the sequence against a concrete alley background with a wall and parked car.

A person performs push-ups using a large exercise ball as support. The ball exhibits slight rolling motion due to the person's hand and foot pressure, while the person's body moves up and down in controlled push-up motion.

The background features stationary stone walls and a paved road with a parked car. No shifting background or environmental fluids (fire, water, smoke, wind) are present. Static elements remain stable throughout the frame.


A woman in a dark patterned top adjusts the sari of a woman in a light yellow top with intricate red and green embroidery, positioning the sari over the seated woman's shoulder; the scene then cuts to black.

The camera maintains a steady ground-level perspective throughout the sequence.

The primary solid object is the female athlete performing a shot put throw: she rotates, steps, and releases the shot put. Secondary objects include a standing observer and a man with a device, who exhibit minimal motion (e.g., slight stepping).

The background (bushes, fence, ground) shows no significant fluid motion (e.g., wind, water) or shifting. A stadium light becomes visible in later frames, but this is a lighting change, not environmental motion.


A silver adjustable wrench with a medium size and open jaws interacts with a dark hexagonal bolt positioned on a metal work surface. The wrench's jaws open and close around the bolt, gripping it while applying turning motion, with the bolt remaining stationary. The camera maintains a close-up perspective with minimal movement, focusing on the mechanical interaction between the wrench and bolt.

A single adjustable wrench is moving, exhibiting discrete physical motion (opening/closing jaws) as it interacts with a nut on the metal surface.

The background consists of a static metal surface with no fluid or gaseous motion (e.g., fire, water, smoke). No uniform background shifts observed.


A person in a maroon shirt plays an orange drum kit, initially viewed from behind in a close-up shot capturing their arm movements. The camera then transitions to a wider angle, revealing the person facing forward with headphones, continuing to drum while positioned in front of a blue chair and musical equipment. The scene maintains focus on the drummer's motion as the camera shifts to medium-wide shots, emphasizing the drum kit's orange color and the person’s active playing stance.

A drummer is actively striking the drum set with drumsticks; the drummer's arms and hands move in discrete motions to hit the drums.

Chef's hands moving to manipulate a pile of chopped vegetables; the vegetables are being moved by the chef's actions.

Background is stationary (kitchen elements without shifting). No fire, water, smoke, or wind present. Thus, no ambient environmental motion.


RAW CAPTION: Okay, let's tackle this video captioning task. The user provided a video of horse racing, and I need to generate a concise chronological paragraph following their specific rules.

First, I need to identify the main subjects. The video shows multiple jockeys on horses. Let me check the frames: in the first frame, there are three horses racing. The jockeys are wearing different colored silks, like white and dark blue. The horses are various colors—brown, maybe a chestnut, and another brown. They're moving quickly across a green field.

Next, I should note the chronological order. The video starts with the horses galloping, then maybe a shift in positions. In frame 2, the horses are still close together, maybe the white-jacketed rider is leading. Frame 3 shows a change in the background, with a white structure. Frame 4 has the horses getting closer, maybe some jostling. The last frame has them almost neck and neck.

I need to mention the appearance briefly: number of horses (three), colors (brown, chestnut), jockeys' silks (white, dark blue). Spatial relationships: the white-jacketed horse is ahead initially, then others catch up. Background is minimal, just the field and some trees in the distance.

Camera perspective: it's a side view, probably following the race, maybe panning left to follow the horses' movement. The camera might have a slight shake due to the speed.

Rules say to exclude text, named characters, so no mention of specific names or logos. Just focus on motion, appearance, positions.

Let me structure it step by step. Start with the horses moving rapidly. Describe the jockeys and horses' colors. Then mention the changing positions over time—maybe the white-jacketed rider leads, then others overtake. Conclude with camera movement.

Check for minimal background: the field and trees are there but not essential, so just mention the green field. Avoid any mention of the background details unless necessary.

Wait, the user says "background descriptions minimal unless essential for understanding motion." Since the motion is the race on the field, maybe just say "green field" is enough.

Let me draft:

"Three jockeys on chestnut and brown horses race rapidly across a green field. The rider in white silks leads initially, followed closely by others in dark blue. As the race progresses, the horses jostle, with the white-jacketed horse maintaining a slight lead before being overtaken. The camera follows the pack with a steady side pan, capturing the dynamic gallop."

Check the rules: chronological order? Yes, starting with the initial positions, then the movement. Mention appearance (colors, number), spatial relationships (leads, overtaken), camera movement (side pan). Background minimal. No text or names.

Wait, the user said "conclude with camera perspective and movement". So end with camera perspective. The example in the rules says "top-down, pan left, slight shake". Here, it's a side pan, maybe a slight shake due to speed?

The original video might have a slight shake, but the user's example mentions "slight shake" as a possible camera movement. Let me check the frames. The video seems to have a steady camera following the horses, but maybe some shake from the movement. However, the user's instruction says "briefly describe their appearance and number (color, size, orientation)." Size might not be necessary, but color is. Wait, the rules say "briefly describe their appearance and number (color, size, orientation)." So maybe mention size? But in the video, the horses are similar in size. Maybe "three horses of varying chestnut and brown hues" and "jockeys in white and dark blue silks".

Wait, the first frame shows three horses. Let me count again: frame 0: three horses, frame 1: still three, frame 2: three, frame 3: three, frame 4: three. So three horses total.

So in the caption: "Three jockeys ride chestnut and brown horses at high speed across a green field. The jockey in white silks leads initially, followed by two riders in dark blue; as the race progresses, the horses close the gap, with the white-jacketed horse maintaining a slight lead before being overtaken. The camera pans steadily left, capturing the dynamic motion of the galloping horses."

Check if the camera movement is correct. The video starts with a view from the side, possibly moving left to follow the horses. Since it's a race, the camera might pan left to keep the horses in frame as they move from left to right. So "pan left" makes sense.

Also, the background is minimal: "green field" and maybe trees, but rule


Two individuals, both wearing green helmets, ride Segways side by side on a narrow road. The left person wears a black tank top while the right wears a gray shirt; their Segways have blue displays and black wheels. Initially stationary, they begin moving forward, with the Segways' orange wheels visible as they advance. The camera follows them from a slightly shaky perspective.

Two people on Segway scooters are moving forward and turning, driven by their own locomotion. The Segways are also moving due to the riders' actions.

The background (path and vegetation) is static and shows no significant motion. There are no environmental fluids (fire, water, smoke) dominating the scene.


A person in a light-colored shirt bends forward, reaching toward an object on the ground, with their hands moving toward and adjusting their posture around the item. The camera maintains a close-up view with slight shake, focusing on the person's actions against a dark background with minimal spatial context.

A person is moving within the room, visible as a reflection in the window. The motion is consistent with walking or shifting position.

The background (outside the window) is static and dark, with no signs of fire, water, or wind. The interior window frame is fixed and non-shifting.


RAW CAPTION: Got it, let's tackle this. The video starts with a person in a red shirt, black shorts, blue shoes standing in a gym. They take a few steps forward. Then there's a lens flare transition to text, but we need to exclude text recognition. So focus on the person's motion. The main subject is the person moving in the gym. Chronologically: first standing, then walking forward. Appearance: red shirt, black shorts, blue shoes. Background is gym with equipment, but minimal. Camera is static? Wait, the first part shows the person moving, then the lens flare. Wait, the video has frames 0-5: person moves, then a bright lens flare with text. But rules say exclude text recognition. So the motion: person in red shirt, black shorts, blue shoes stands in a gym, takes a few steps forward, then a lens flare transitions (but the transition is visual, not the person). Wait, the task is to describe the motion and behavior of main subjects chronologically. So the person's action: starts standing, then walks forward. Then the lens flare (which is a visual effect, not the subject). So the caption should be about the person's movement. Let's structure it.

First, the person (male, red shirt, black shorts, blue shoes) is in a gym. He takes a few steps forward. Then the scene transitions to a bright lens flare (but since we exclude text recognition, maybe the lens flare is part of the visual but not the main subject). Wait, the rules say exclude text recognition, but the lens flare is a camera effect. But the main subject is the person. Let's see: the first part shows the person moving, then the video cuts to a lens flare with text. But the task is to describe the motion of the main subject. So the person's movement: he begins standing still, then walks a few steps forward, then the scene changes to a lens flare. But the caption must be concise, chronological. So:

A person wearing a red shirt, black shorts, and blue shoes stands in a gym, then takes a few steps forward. The scene transitions to a bright lens flare effect.

But check the rules: mention spatial relationships if relevant. The gym is the background, so minimal. Camera perspective: probably static, but the problem is the first part—camera is static as the person moves. The lens flare is a transition. So the caption should be about the person's actions first, then the transition.

Wait, the video has frames 0-5: first frame, person is standing. Then frame 1, 2, 3: person takes steps forward. Then frame 4,5: lens flare. So the chronological order is: person stands, walks forward, then lens flare.

So the caption: A person in a red shirt, black shorts, and blue shoes stands in a gym, then walks a few steps forward before the scene transitions to a bright lens flare.

But check if the background is minimal. Yes, gym is mentioned, but minimal. The main subject is the person. The camera perspective: for the person part, it's a static camera. The lens flare is a transition, not a camera movement.

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

So for the first part, when the person is moving, the camera is static (since it's a fixed frame). Then when the lens flare happens, that's a transition. But the main motion is the person walking.

So let's draft:

A person wearing a red shirt, black shorts, and blue shoes stands in a gym, then walks a few steps forward. The scene ends with a bright lens flare effect, captured from a static camera angle.

But need to be concise. Let's see. Rules: "concise, chronological paragraph". So:

In a gym setting, a person in a red shirt, black shorts, and blue shoes takes a few steps forward from a standing position. The video then transitions to a bright lens flare effect.

Check rules: exclude text recognition (text is part of the lens flare but we're not to recognize it, so we just mention the effect). Mention appearance: yes. Chronological: standing, walking, then transition. Camera perspective: static during the person's movement, but the transition is a lens flare. Wait, the lens flare is a camera effect, so maybe the camera is static during the person's actions. So the caption should say the camera is static for the first part.

Wait, the problem says "conclude with camera perspective and movement". So the camera is static during the person's movement. Then the transition to lens flare is a change. So:

A person in a red shirt,

A person is moving their arms, which is a discrete solid object moving due to self-generated locomotion.

The background in the gym is static with no shifting. No fire, water, smoke, or wind is present. The title card segment (4.0-5.0) shows lens flares (camera artifacts) but no ambient environmental motion.


A man in a black shirt sits at a grand piano, his hands moving rhythmically over the keys as he plays. Sheet music is visible on the piano's music stand. The camera remains stationary, capturing the scene from a fixed angle with minimal background details.

A person (pianist) with solid, distinct hands and body moving via muscular action to press piano keys, exhibiting clear locomotion of discrete objects.

Background elements (piano bench, sheet music, walls) show no shifting or fluid motion; no fire, water, smoke, or wind present.


A person in a pink top and light shorts runs toward the camera, then falls forward onto the grass. A second person in a blue shirt and dark shorts follows, falling to the ground nearby. Both individuals roll and adjust their positions on the lawn. The camera remains stationary, capturing the scene from a fixed position.

Two people are the discrete objects: the first performs a backflip, lands, and interacts with the second person (who is lying on the grass), with movements driven by physical forces (e.g., flips, rolling, arm movements).

Background elements (house, plants, grass) show no uniform shifting or environmental fluid motion (e.g., no fire, water, wind). Static background remains consistent across frames.


A person wearing a maroon hoodie plays a black keyboard with white and black keys, their hands moving rhythmically across the keys. The keyboard features a blue light at the bottom. The camera maintains a close-up, static perspective focusing on the hands and instrument, with a wooden background partially visible.

The person's hands are moving on the keyboard, representing discrete solid objects in motion due to physical interaction with the keyboard.

The wooden wall background shows no shifting or fluid motion (fire, water, smoke, wind); background elements remain static.


A person with long dark hair and dark clothing takes a photo with a phone in a tree-lined urban area, then walks across a street while holding the phone, stands near a storefront as a red car passes by, and appears on a city street with parked bicycles and a digital display. Finally, she stands by a tree in a park-like setting as the camera follows her movement through the urban environment.

The woman is the primary discrete object moving via locomotion (walking) in multiple segments. She holds and interacts with a phone, indicating intentional movement. Bicycles and parked vehicles are stationary in the background.

Background elements (trees, fence, buildings, bicycles) remain static throughout all segments. No ambient environmental motion (fire, water, smoke, or wind) observed; trees show minimal swaying but not dominant fluid motion.


RAW CAPTION: Got it, let's break this down. First, the video shows a man in a gray vest and white shirt sawing a log. He's leaning forward, using the saw. The log is on a wooden stand. There are people around: a woman in a black vest and white shirt sitting on the stand, a girl in a pink dress standing to the right, and another person in a light blue shirt also on the right. The background has greenery and red mulch. The man is moving the saw back and forth, so the motion is continuous. The camera seems stationary, maybe a slight shake but not much. Need to describe the sequence: man starts sawing, moves the saw, people watching. Keep it chronological. Check rules: focus on motion, appearance (clothes), spatial relationships (man in front, others behind), camera perspective. Background minimal. Exclude names, text. Let's structure the caption.

Start with the main action: A man in a gray vest and white shirt, standing on red mulch, uses a yellow-handled saw to cut a log placed on a wooden stand. He leans forward, back-and-forth motion, sawing. To his left is a white plastic chair. Behind him, a woman in a black vest over a white shirt sits on the stand, a girl in a pink dress and another person in a light blue shirt stand nearby. The camera remains stationary with minimal movement, capturing the scene from a fixed angle. Need to check if all parts are covered. Make it concise, chronological. Let's draft:

A man wearing a gray vest, white shirt, and dark pants saws a log on a wooden stand, leaning forward with a yellow-handled saw in a back-and-forth motion. To his left is a white plastic chair; behind him, a woman in a black vest over a white shirt sits on the stand, while a girl in a pink dress and another person in a light blue shirt stand to the right. The camera maintains a stationary perspective, capturing the scene with minimal movement.

Wait, check if "to his left" is correct. In the video, the white chair is to the left of the man. The people behind are to the right? Let me check the image: man is in the center, white chair to his left. The wooden stand is where the log is, and people are behind the stand? Wait, the woman is sitting on the stand, so the stand is a structure, maybe a bench. The girl in pink is standing to the right of the stand. So spatial relationships: man sawing log on stand, white chair to his left, people (woman, girl, other) behind or to the right of the stand.

Okay, let's refine:

A man in a gray vest, white shirt, and dark pants uses a yellow-handled saw to cut a log resting on a wooden stand, moving the saw in a back-and-forth motion while leaning forward. To his left, a white plastic chair sits on the red mulch-covered ground. Behind the stand, a woman in a black vest over a white shirt sits, a girl in a pink dress and another person in a light blue shirt stand to the right. The camera remains stationary with minimal movement, observing the scene from a fixed angle.

Check if it's concise, chronological. The action is sawing, so sequence is man starting to saw, continuing. Background is red mulch, greenery but minimal. Rules say keep background minimal. So maybe not mention red mulch? Wait, the first rule: "Background descriptions minimal unless essential for understanding motion." The red mulch is part of the setting but maybe not essential. But the video shows red mulch, but perhaps better to focus on key elements.

Wait, the first rule: "Focus primarily on the motion and behavior of main subjects (people/animals/objects) in chronological order." So main subject is the man sawing. Others are background. So:

A man in a gray vest, white shirt, and dark pants saws a log on a wooden stand, moving the saw back and forth while leaning forward. To his left, a white plastic chair is visible; behind him, a woman in a black vest over a white shirt sits on the stand, while a girl in a pink dress and another person in a light blue shirt stand to the right. The camera remains stationary, capturing the scene without significant movement.

Check length. Need to be concise. Maybe:

A man wearing a gray vest and white shirt uses a yellow-handled saw to cut a log on a wooden stand, leaning forward with a back-and-forth motion. To his left is a white plastic chair; behind him, a woman in a black vest over a white shirt sits, a girl in a pink dress, and another person in a light blue shirt stand to the right. The camera remains stationary with minimal movement.

Yes

A man is actively swinging an axe to chop wood, with visible motion of the axe and his body. Other people are stationary observers.

Background elements (white chair, trees, building) are stationary; no fluid/environmental motion (fire, water, wind) present.


RAW CAPTION: Got it, let's break this down. The video starts with a close-up of a blender on a counter. The blender has a pinkish liquid, maybe a smoothie. There's a bottle and a blue cup next to it. Then the camera moves quickly, showing a person (but maybe not the face) waving? Wait, the second frame says "a person waves their hand" but the instruction says to describe motion. Let's check the frames:

Frame 0: Blender on counter, pink liquid. Bottle and cup nearby.

Frame 1: Same as 0, maybe slightly different angle. Still blender, bottle, cup.

Frame 2: Person waves hand (but it's a bit blurred). Then camera shifts to show the person (maybe) in the kitchen, near fridge. Wait, the frames are sequential. Let's list each frame's content:

- [0.0] Blender on counter, pink liquid, bottle and blue cup visible.

- [1.0] Similar, blender still, bottle and cup.

- [2.0] Camera moves, shows a person (possibly) waving hand, then the scene shifts to a different part of the kitchen (maybe the person moving).

- [3.0] Another quick movement, maybe the person walking.

- [4.0] Person opening a door (white door, maybe a kitchen cabinet or pantry).

Now, need to describe chronologically. Main subjects: blender, bottle, cup, person (maybe). The blender is stationary initially, then the camera moves around. The person appears in frame 2, waving, then moving, then opening a door.

Wait, the problem says "main subjects (people/animals/objects)". So blender is an object. The person is a main subject. Let's structure:

Starts with close-up of a white blender with pink liquid on a kitchen counter, next to a white bottle and blue cup. The camera then shifts to show a person waving their hand, followed by a quick pan to the right where the person moves through the kitchen (near refrigerator and sink). The camera then captures the person opening a white door, with a wooden floor and cabinet visible. The camera moves erratically throughout, including a slight shake.

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

- Initial frame: blender (white, pink liquid) on counter, bottle (white) and blue cup beside it.

- Then camera moves, showing a person (appears to wave) in the kitchen.

- Then the person moves towards a door, opens it.

- Camera is handheld, moving quickly, with some shake.

Check rules: focus on motion of main subjects. Objects: blender, bottle, cup. Person: waving, moving, opening door.

Chronological order: first blender on counter, then person waves (maybe the camera is held by the person), then person moves, opens door.

Wait, the frames: [0] blender; [1] blender (same); [2] person waving; [3] person moving (maybe); [4] person opening door.

So sequence: starts with blender, then camera shifts to person waving, then person walks towards door, opens it.

Now, describe appearance: blender white, liquid pink; bottle white; cup blue; person is in kitchen (maybe wearing patterned shirt, but description should be brief—color? Maybe not specified, so just "person").

Spatial: blender on counter, bottle and cup next to it. Person is in kitchen, moving towards door.

Camera movement: starts with close-up, then pans (quickly) to show person, then moves towards door, ends with person opening door. Camera has shake, quick movements.

Putting it all together:

The video opens with a close-up of a white blender containing pink liquid on a kitchen counter, with a white bottle and blue cup nearby. The camera then quickly shifts to show a person waving their hand, followed by the person moving through the kitchen area toward a white door, which they open. The camera remains handheld, exhibiting slight shake and erratic movement throughout.

Check rules: exclude text recognition (no labels), minimal background. Mention motion: blender is stationary, then camera moves to person, person moves, opens door. Mention appearance of main subjects: blender (white, pink liquid), bottle (white), cup (blue), person (waving, moving). Spatial: blender on counter, next to bottle and cup; person in kitchen, moving to door.

Wait, the output must be a concise paragraph. Let's condense:

A white blender with pink liquid sits on a counter next to a white bottle and blue cup. The camera quickly pans to show a person waving their hand in the kitchen, then the person moves toward and opens a white door. The camera moves erratically with slight shake throughout.

Check if all rules are met:

a) Motion: blender (stationary), camera moves, person waves

Brief description of discrete objects moving

Brief description of background and ambient


RAW CAPTION: Okay, let's tackle this video caption request. First, I need to understand the rules. The user wants a concise, chronological paragraph focusing on the motion and behavior of the main subjects, which are the people and horses. They also want the appearance details like color and number, spatial relationships, camera perspective, and minimal background.

Looking at the video frames provided. The first frame shows several riders on horses in a field. There are three people: one in orange, others in different colors. The horses are various colors like white, brown, black. Background has trees and a building.

In the next frames, the action starts. The riders are moving, maybe galloping. The rider in orange is on a white horse, others follow. There's a rider in white on a brown horse approaching. Then, the rider in orange's horse bucks or moves quickly, causing a moment where the rider might be adjusting.

Need to track the sequence. The first part shows the initial setup with multiple riders. Then movement starts, they gallop, maybe some interaction between riders. The spatial relationships would be like "the rider in orange is ahead, others follow behind." Camera seems to follow the action, possibly panning to keep up with the moving riders. Background is minimal, just trees and a building, so maybe mention the field and trees briefly.

Check the rules: exclude text, named characters. Focus on motion. So the main points are the riders on horses moving, their colors, the action of galloping, maybe the horse's movement (like bucking), then the camera follows.

Need to make sure it's chronological. Start with the initial scene, then the riders moving, the horse action, and the camera movement.

Let me structure it: At the start, multiple riders on horses in a grassy field. Then, they start galloping. The rider in orange (white horse) leads, followed by others. Then the horse in front (white) bucks or moves quickly, causing the rider to adjust. The camera follows the movement, panning slightly to capture the action.

Check the appearance: number of riders, colors. There are four riders in total. The rider in orange is on a white horse, others on different colored horses (brown, black). The camera moves with the action, probably tracking the main rider.

Wait, the video has 5 frames. The second frame shows a rider on a white horse approaching from the right. Third frame, the white horse and orange rider move towards each other. Fourth frame, they pass each other. Then fifth frame, the riders continue moving.

Wait, maybe the sequence is: riders start moving, a rider in white on brown horse approaches from the right, the orange rider's white horse gallops towards him, they pass each other, then the other riders follow. The camera follows the movement.

Wait, the first frame: riders are moving left to right. The second frame: a rider in white on brown horse comes into view from the right, moving left. Then the orange rider on white horse is ahead. Then in the third frame, the white horse and the brown horse gallop towards each other. Then in the fourth frame, they pass each other, with the white horse moving ahead. The last frame shows riders continuing.

Hmm. Maybe the main action is the rider in orange (white horse) leading, followed by others. Then the rider in white (brown horse) approaches from the right, they pass each other. Then the white horse continues ahead, others follow.

So the chronological order would be: Initially, riders on horses in the field. Then, a rider in white on a brown horse gallops from the right, approaching the group. The rider in orange on a white horse leads the group. As the white horse moves forward, the brown horse rider catches up, and they pass each other. The other riders follow behind. The camera stays focused on the main action, panning to follow the movement.

Now, to condense this into a concise paragraph. Start with the initial scene, then the actions in order. Mention the number of riders (four), their horse colors. The rider in orange is on a white horse, others on brown and black. The camera follows the movement.

Check if background is essential. The video has trees and a building in the background, but the rules say minimal unless essential. Since the motion is in the field, maybe just mention the grassy field and trees briefly.

Wait, the first frame shows trees and a building. But maybe the caption can just mention the field and the background is trees and a building.

Let me try writing:

Four riders on horses gallop across a grassy field bordered by trees. A rider in an orange shirt on a white horse leads, followed by riders on brown and black horses. The white horse and a rider in white on a brown horse approach each other, their horses moving rapidly. They

Multiple riders on horses moving across the field; motion is due to locomotion of the horses under rider control. Riders and horses are distinct solid objects with clear bounding boxes.

Background elements (trees, barn, distant mountains) remain static with no shifting or fluid motion. No fire, water, smoke, or wind effects observed; trees are stationary with no swaying.


RAW CAPTION: Okay, let's tackle this video captioning task. The user wants a concise chronological paragraph following specific rules. First, I need to focus on the main subjects: the clown and the kids. The clown is in a yellow shirt, purple pants, orange hair, and a red hat. There are two kids, a girl with blonde hair and a boy. The clown is interacting with them, maybe handing something over. The background has people walking, but I should keep it minimal.

Start with the clown's actions. The video starts with the clown standing next to a cart, then he's talking to the kids. He gestures with his hands. The kids are facing him, the girl is on the left, boy on the right. The cart has items, maybe a green box and cups. Camera is stationary, maybe a slight shake. Need to mention the sequence: clown moves hands, interacts, kids look at him. Background people are in the distance. Don't mention the cart's items too much. Check the rules: avoid text, names, stylistic analysis. Keep it chronological. Let me structure it step by step.

First, the clown is standing by the cart, engaging with two children. He gestures, then maybe hands something. The kids are attentive. Background has a crowd. Camera stays focused on them. Need to make sure it's all in order, concise. Avoid details like the cart's contents. Maybe mention the cart's wheel as part of the setup. Check the rules again: no text recognition, so skip any labels on the cart. Also, the clown's suspenders and gloves. Should include appearance briefly.

Wait, the rules say "briefly describe their appearance and number (color, size, orientation)." So clown: orange hair, yellow shirt, purple pants, red hat. Two kids: girl with blonde ponytail, boy next to her. Spatial: clown is in front of cart, kids facing him. Camera is steady but might have a slight shake. Background is blurred crowd. So the caption should flow: starting with the clown's position and actions, then the kids, then camera.

Let me draft: A clown in a yellow shirt, purple pants, orange hair, and red hat stands by a cart with a white wheel, interacting with two children—a blonde girl and a boy—while gesturing with white-gloved hands. The clown moves slightly, facing the children as they remain attentive. In the background, people walk, but the focus stays on the clown and children. The camera maintains a steady perspective with minor shaking.

Wait, the video starts with the clown standing, then maybe turning slightly. The kids are looking at him. Need to make it chronological: clown is talking, moving hands, kids listening. Maybe "The clown gestures with his hands while speaking to the children, who look up at him." But check if the actions are in order. The first frame shows the clown holding something, then in later frames he's gesturing. So perhaps he's handing an object to the kids. Wait, the user's example might have that.

Wait, the user's example in the problem: the clown is holding something in his hand at first, then gestures. The video might show the clown giving an item to the kids. But the rules say exclude text recognition, so even if he's holding a lollipop, don't mention. Just say "handed to the children" without specifying.

Wait, the problem says "describe the motion and behavior of main subjects in chronological order." So first, the clown is standing near the cart. Then he's interacting with the kids, maybe giving something. Then the kids are looking at him.

Wait, the frames show the clown moving his hands from holding something to gesturing. So: The clown in a yellow shirt, purple pants, and orange wig gestures with white-gloved hands while speaking to two children—a blonde girl and a boy—standing in front of him. He shifts his stance slightly, maintaining engagement as the children remain attentive. The background features blurred figures walking. The camera remains stationary with minor shake.

But need to check for minimal background. The rules say "mention spatial relationships if relevant," so maybe "a cart with a white wheel is behind the clown."

Wait, the cart is on the left side of the clown. The clown is standing next to it. So "The clown stands beside a cart with a white wheel, interacting with two children positioned in front of him."

Okay, let's structure it:

A clown in a yellow shirt, purple pants, orange wig, and red hat stands beside a cart with a white wheel, engaging two children—a blonde girl with a ponytail and a boy—positioned in front of him. The clown gestures with white-gloved hands while speaking, shifting his stance slightly as the children maintain eye contact. In the background, people walk, but the focus remains on the clown and children

Clown performs hand gestures (e.g., crossing arms, pointing), and children turn heads. All motions are discrete, solid-object movements driven by physical actions (clown's locomotion and children's head/shoulder shifts).

Background elements (fence, wheel, distant people) show minimal movement; no fire, water, smoke, or wind visible. Background remains largely static with no uniform shifting.


RAW CAPTION: Okay, let me tackle this video captioning task. First, I need to understand the user's requirements. They want a concise, chronological paragraph that describes the video based on the provided frames. The rules are pretty specific, so I need to make sure I follow them all.

Starting with the first frame: a woman is sitting on the floor in a kitchen. She's wearing a white shirt and black pants, with long dark hair. She's holding something, maybe a coconut, and she's looking down. The kitchen has cabinets, a window, and a chair in the background. The lighting is bright from the window.

In the second frame, she's still sitting but now she's holding her hands together, maybe cradling the coconut. Her posture is the same, but her hands are moving. The background remains the same.

Third frame: she's holding a coconut, which is now open. The coconut halves are visible, and she's turning it towards the camera. Her hair is still long and dark, and she's wearing the same clothes.

Fourth frame: she's lifting the coconut up, showing the inside. The camera angle seems to be low, close to the floor, looking up at her.

Fifth frame: she's holding a coconut half with a white interior, smiling at the camera. The background is still the kitchen, same furniture.

Wait, but the user said to focus on motion and behavior in chronological order. Let me sequence the actions step by step.

1. The woman is sitting on the floor, holding a coconut. She opens it, showing the inside. Then she lifts it up to display the interior. Finally, she holds it up while smiling.

The background is a kitchen with cabinets, a window, chair, and fire extinguisher. But according to rule e, background descriptions should be minimal unless essential. So maybe just mention the kitchen briefly.

The camera perspective: in the first few frames, it's a low angle, looking up at her. Then maybe it stays low as she moves the coconut.

Rule d says conclude with camera perspective and movement. The camera seems to be stationary but slightly tilted upwards, maybe a low-angle shot. The movement might be slight shake or pan? Wait, in the provided frames, the camera angle changes slightly as she moves. But maybe it's mostly static.

Wait, the output needs to be a paragraph in chronological order. Let me structure it:

- Start with her sitting on the floor in kitchen, holding coconut.
- Then she opens it, shows the inside, lifts it up.
- Finally, holds it towards camera while smiling.

Appearance: woman with long dark hair, white shirt, black pants. The coconut is brown with white interior.

Spatial relationships: she's in the kitchen, cabinets to the left, window behind her.

But rule c says mention spatial relationships if relevant. Maybe just "sitting on floor in kitchen with cabinets to left and window behind".

But need to keep it minimal. Let's see:

"A woman with long dark hair, wearing a white shirt and black pants, sits on the kitchen floor. She holds a brown coconut, opens it, and lifts the halves to display the white interior. She smiles while holding the coconut towards the camera. The camera maintains a low-angle perspective, slightly tilted upward, capturing her movements from the floor level."

Wait, but the rules say to exclude text recognition (like the "cook with a little Indian" logo), which is present in the fifth frame. So just focus on the action.

Check if all rules are followed:

a) Motion in order: sitting, opening coconut, lifting, showing interior, smiling.

b) Appearance: woman's hair, clothes, coconut color.

c) Spatial: kitchen, cabinets to left, window behind. But maybe minimal, so just "kitchen floor".

d) Camera perspective: low angle, slightly tilted upward.

e) Background minimal: kitchen mentioned once.

f) Exclude text, so no mention of the logo.

g) No reasoning in output.

Let me draft:

"A woman with long dark hair, wearing a white shirt and black pants, sits on a kitchen floor. She holds a brown coconut, opens it, and lifts the halves to display the white interior. She smiles while holding the coconut towards the camera. The camera remains in a low-angle position, capturing her movements from floor level."

Wait, the fifth frame shows her holding the coconut half with white interior. The action sequence is:

- Sitting and holding coconut (frame 0)
- Opening coconut (frame 1-3)
- Lifting to show interior (frame 4)
- Holding up and smiling (frame 5)

So the chronological order is: she starts sitting, then opens the coconut, lifts it to show the inside, then holds it up while smiling.

The camera angle is low, looking up at her the entire time.

Also, note the coconut's color: brown shell

A person moves their body (sitting to standing) and manipulates a coconut (holding, opening), demonstrating discrete solid-object motion via physical interaction.

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


A person wearing a light-colored t-shirt and blue jeans sits while playing a black electric guitar, their hands moving rhythmically over the fretboard and strings. The scene remains static with the camera fixed on the subject, showing minimal background details.

A person playing a guitar; hand movements on the fretboard and strumming motion are discrete solid-object actions.

Background elements (white curtain, blue floor, structural beams) remain static with no shifting or fluid motion; no fire, water, or wind detected.


tags. Keep it concise.  Try: A person in a white shirt and black tie pours liquid from a small container into a cup, then lifts the cup and places it on a saucer on the counter. The camera follows the cup's movement, remaining mostly stationary with slight adjustments to track the action.  Check rules: motion (pouring, lifting, placing), appearance (white shirt, black tie), spatial (counter, saucer), camera (follows cup, slight adjustments). Background minimal. No text or named characters.  Yes, that should work. </think>  <caption_output>A person wearing a white shirt and black tie pours liquid from a small container into a cup, then lifts the cup and places it on a saucer on the counter. The camera follows the cup's movement, remaining mostly stationary with slight adjustments to track the action.

A person performs discrete actions: pouring liquid into a cup, holding the cup, and placing it on a saucer. The motion involves solid objects (cup, container, hands) moving due to intentional physical actions.

Background elements (kitchen appliances, counters) show no uniform shifting or fluid motion (fire, water, smoke). No dominant environmental forces are present.


A yellow excavator with its arm extended digs into a pile of dirt, its bucket scooping and moving soil. An operator wearing an orange vest is visible inside the cabin. The machine remains stationary while the arm operates, displacing earth. The camera maintains a fixed ground-level perspective.

Yellow excavator arm is moving to dig into soil, displacing earth through hydraulic action (discrete solid object movement).

Background elements (greenery, ground) are static with no uniform shifting or fluid/environmental motion (e.g., no water flow, smoke, or wind).


A person wearing beige pants, brown shoes, and a black leg brace walks using two silver crutches on a carpeted floor, moving forward in a rhythmic pattern as they shift weight onto the crutches and lift their braced leg. The camera follows the movement with a slight pan to capture the lower body motion.

A person wearing a leg brace and crutches is walking. Discrete solid objects in motion: the lower legs (with brace), the crutches, and the shoes. Motion is cyclic stepping forward and weight transfer.

The background consists of a static carpeted floor and stationary objects (e.g., white bag). No shifting background elements, fluid motions (fire/water/smoke), or wind effects are observed.


A person with purple-painted nails, a gold watch, and rings styles another person's short brown hair. The stylist's hands move through the hair from the top, pulling and adjusting, working around the head while the recipient lies with eyes closed, head tilted back. The camera maintains a close-up angle, tracking the hands' motion.

Two discrete objects: a person (head and upper body) and a hand (with watch and ring). The hand is actively manipulating the person's head through physical contact, causing deliberate motion of both objects.

No shifting background elements or fluid/environmental motion (fire, water, wind) detected. Background is dark and static with no uniform movement of environmental features.


A person with a ring on their left hand plays a keyboard, their hands moving rhythmically across the black and white keys. The camera initially captures a top-down view of the hands, then shifts to a side angle showing the person's arms and the keyboard's dark body with circular vents. The hands press the keys in a coordinated motion, with minimal background details visible beyond the instrument and the player's torso. The camera remains steady throughout, focusing closely on the playing action.

The person's hands are moving on the keyboard keys to play the instrument; the accordion bellows are also moving as part of the instrument.

The background (accordion bellows and wall) is static with no fluid or environmental motion. The bellows movement is part of the instrument and driven by the player.


Two men sit in a kitchen; the left man, in a black shirt and cap with orange brim, plays an accordion, while the right man, in a black shirt and blue cap, plays a guitar. Both lean downward to adjust their instruments, then the accordion player looks up while the guitarist maintains focus on the guitar. The camera remains static throughout.

Two seated individuals exhibit discrete movements: the left person adjusts posture and handles an object (likely a book), while the right person manipulates items on the table.

The kitchen background (cabinets, countertops) shows no uniform shifting or fluid/environmental motion (fire, water, smoke, wind). Static elements remain stable across frames.


A person in a red jacket and dark pants skis across a snow-covered landscape, moving from left to right while kicking up snow. They navigate using ski poles, pass a series of thin marker poles, and continue skiing toward the right side of the frame. The camera remains stationary but exhibits a slight shake, capturing the scene from a distant perspective.

A single skier is moving across the snow, using ski poles for propulsion. The skier's motion is due to their own locomotion and is easily trackable.

The background consists of a snowy landscape with trees and mist. The mist is static and does not show significant fluid motion (e.g., wind-driven movement), and the background elements are fixed. There is no dominant environmental fluid motion.


A man in a green shirt, gray shorts, blue shoes, and a knee pad lifts a barbell from waist height to his shoulders, then overhead in a gym. Another person stands in the background near gym equipment. The camera remains stationary throughout.

The person in the green shirt and black shorts is lifting a barbell, exhibiting clear locomotion (bending, lifting, holding) due to physical forces. The barbell is a discrete object moving with the person.

The gym background (walls, weight racks, equipment) remains stationary with no uniform shifting or fluid motion. No fire, water, or wind effects are present.


RAW CAPTION: Okay, let's tackle this video captioning task. First, I need to understand what the user is asking for. They want a concise, chronological paragraph that describes the video based on the given rules.

Looking at the video frames provided: There are two women in a room. One is lifting the other. The setting has a blue mat, a couch with a patterned cover, some furniture, and a mirror. The main action is the woman in black lifting the other woman in a black top and plaid shorts. The lifted woman is holding a mirror.

I need to focus on the motion and behavior in order. The first part shows the woman in black lifting the other, who is holding a mirror. Then the lifted woman is lifted higher, and then she's let down. The caption should mention the appearance briefly: the woman lifting is in black, the other has a plaid skirt. The spatial relationship is the lifted woman being held above the other. Background elements like the couch and mirror are minimal but necessary for context.

Wait, the rules say to exclude text recognition, so ignore the website at the bottom. Also, no named characters. So just describe their actions.

Check the rules again: chronological order, appearance (color, size, orientation), spatial relationships, camera perspective, minimal background.

The camera seems static, maybe a slight shake? The video frames show the same angle, so probably fixed camera. The description should mention that the camera is stationary.

Let me structure it:

Two women, one in black top and plaid skirt, the other in black tank top. The woman in tank top lifts the other, who holds a mirror. As she lifts, the other woman's position changes from standing to being raised, then lowered. Background includes a couch and mirror, but keep it minimal.

Wait, the video shows the woman being lifted, then she steps out of the frame, maybe the lift is completed. Let's check the frames:

Frame 0: Woman A holds Woman B, who has a mirror. Woman B's leg is up.

Frame 1: Similar, but Woman B's position changes slightly.

Frame 2: Woman A lifts Woman B higher.

Frame 3: Woman B is higher, leg is extended.

Frame 4: Woman A lowers Woman B.

Frame 5: Woman A stands alone.

So the chronological order is Woman A lifting Woman B (holding mirror) higher, then lowering her, and finally Woman A is alone.

Appearance: Woman A (black top, skirt), Woman B (black tank top, plaid skirt). Wait, in the video, the woman being lifted is wearing a black top and a plaid skirt. Wait, looking at the description again:

Wait, the first frame: the woman in black is being lifted by the other. Wait, maybe I mixed them up. Let me check the video again.

Wait, the first frame shows two women. One is standing and lifting the other, who is being held up. The woman being held has a plaid skirt and black top. The one lifting is in a black tank top and plaid shorts? Wait, no. Let me look at the frames.

Looking at the first frame: The woman on the bottom (lifting) has a black sleeveless top and plaid shorts. The one being lifted is wearing a black top and plaid skirt. Wait, maybe not. Wait, the description says:

The woman being lifted is holding a mirror. She's wearing a black top and plaid skirt. The one lifting is in black top and plaid shorts? Wait, the problem is that the description might be confusing.

Wait, the user provided the video frames. Let's parse the image:

Frame 0: One woman (left) in black sleeveless top and plaid shorts, lifting another woman (right) who has a black top and plaid skirt. The lifted woman is holding a mirror. Both are on a blue mat. The background has a couch with a red pattern, a mirror on the wall, a table with items.

In frame 1, the lifted woman's leg is raised higher.

Frame 2: Same, more lifted.

Frame 3: The lifted woman is almost up, then in frame 4 she's being lowered.

Frame 5: The lifted woman is down, and the one lifting is alone.

So the main action: The woman in black top and plaid shorts lifts the woman in black top and plaid skirt, who holds a mirror. She's lifted upwards, then lowered.

Appearance: Both women have black tops; one in plaid shorts, the other in plaid skirt. But perhaps the key is to describe them as "one woman in a black sleeveless top and plaid shorts lifting another woman in a black top and plaid skirt who holds a mirror."

But the rules say to mention appearance briefly. So maybe "Two women:

Two people engaged in physical interaction (one lifting the other), exhibiting coordinated leg/arm movements and body shifts due to explicit human locomotion.

Background elements (couch, wall decor, furniture) remain stationary with no shifting or fluid motion; no fire, water, smoke, or wind present.

A person drinking water and swishing liquid in their mouth; motion is discrete and tracked via head movement and water displacement.

The background (walls, clothing rack) remains static throughout; no shifting or fluid motion (fire, water, smoke, wind) observed.


The video opens with multiple people in casual attire walking and interacting around a table filled with brochures and boards; the camera then pans to a different section where a group of individuals, including those in white shirts, are seated around a blue board table, with one person arranging tiles while others observe.

Multiple people moving across the scene (e.g., walking around tables, gesturing during interaction) due to locomotion and physical interactions.

No shifting background elements observed (walls, signs remain fixed relative to each other); no fire, water, or smoke present in the scene.


A man in a black sleeveless shirt, black pants, and white shoes stands in a cluttered gym, holding a barbell. He lifts the barbell overhead in a swift motion, then lowers it to his waist. The camera remains stationary throughout, capturing the exercise in a medium shot.

A man performs a power snatch exercise, lifting a barbell from the ground to overhead. The barbell and man exhibit solid, distinct motion due to explicit physical forces (muscular exertion), with clear tracking of their bounding boxes during the lift.

The background features static gym equipment (weights, mats, walls) with no shifting or fluid motion (fire, water, smoke, wind). Background elements remain uniformly fixed throughout the frame, indicating no ambient environmental motion.


Two individuals in white martial arts uniforms, one with a yellow belt and the other with a black belt, engage in a sparring session. The yellow-belted person advances toward the black-belted opponent, executing a high kick mid-air. The black-belted individual maintains a defensive stance. After the kick, the yellow-belted person retracts their leg and steps back, while the black-belted person adjusts their position. Spectators sit on mats in the background. The camera remains static, capturing the interaction from a frontal perspective.

Two martial artists in white uniforms with belts move dynamically: one executes high kicks and blocks while the other counters with defensive stances and movements. Other seated individuals remain stationary.

Background elements (seated spectators, mats, walls) are static with no fluid or environmental motion. No fire, water, smoke, or wind visible.


A person wearing a red headscarf applies makeup to their eye using a brush while looking into a pink mirror positioned to their left; the mirror reflects the action as the individual adjusts the brush near their eyelid, maintaining a steady close-up camera perspective with minimal background detail.

A person's hand (with makeup brush) moves to apply makeup; this is a solid, discrete object motion.

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


A person in a black jacket places a metallic rectangular tray onto a stainless steel machine labeled "MULTEPAK" in an industrial setting. The tray is slid horizontally onto the machine's surface, where it is positioned. The camera remains stationary, capturing the action from a front perspective with minimal background details.

A sheet of metal is placed on a conveyor belt and moves along it due to the belt's mechanical motion. A person's hand is also visible, but the primary moving object is the metal sheet.

The background (factory floor, machinery) remains stationary. There is no fluid motion (fire, water, smoke) dominating the scene.


A shirtless baby with brown hair sits in front of a curtain, with a bookshelf and television visible to the left; the baby opens their mouth wide, then moves hands toward the chest. The camera maintains a stable frontal view with slight movement.

The baby exhibits discrete facial motion (mouth opening/closing, expressions) as the primary moving object.

Background elements (bookshelf, TV screen) remain static across frames; no shifting or fluid/environmental motion (fire, water, wind) observed.


A small child in a dark shirt and light pants begins crouched near the left side of a soccer goal, then stands and walks directly toward the camera across the grassy yard, passing in front of the goal net. The camera remains stationary with a slight shake throughout the sequence.

A person (solid object) moves toward and interacts with a soccer goal, demonstrating locomotion (running, kicking) and subsequent standing. No other discrete objects show prominent motion.

Background elements (wooden fence, soccer goal, trees) remain static across frames; no significant fluid motion (fire, water, smoke) or large-scale environmental movement (e.g., strong wind) is observed.


A woman in a pink tracksuit walks four dogs (brown, beige, white, black) on leashes along a paved path beside a stone wall, with the black dog trailing to the right. The dogs move in a loose line behind her. The scene transitions to a forest path where the woman continues walking the dogs through wooded terrain. Camera follows her movement, panning left as she progresses.

The person in pink and three dogs (two white, one black) are moving via locomotion (walking). The motion is due to the person walking the dogs, with no collisions or explicit forces other than natural walking.

The static background elements (stone wall, grass, trees) do not shift uniformly across the screen. There is no dominant environmental motion (fire, water, wind) that would classify as ambient_environmental.


A person with curly hair tied up, large white hoop earrings, and a dark top moves a small object toward their mouth with their right hand, then retracts it. The background is a plain white wall. The camera maintains a close-up perspective with minimal movement.

The woman is moving her mouth and hand in discrete actions (eating or speaking).

The background (wall and shelf with a stuffed toy) is static with no environmental motion (fire, water, wind).


RAW CAPTION: Got it, let's break this down. The video shows a baseball game. First, identify the main subjects: players, umpire, catcher. Let's go chronologically.

Start with the initial frame: there's a batter (white uniform, number 17?), umpire in light blue shirt, catcher in dark jersey with number 28. They're near home plate. The pitcher is on the mound. Then, the batter swings, maybe hits the ball. The ball is hit, players run—like the runner from first base (white uniform) heads towards second. Then the umpire gestures, maybe signaling something. The catcher and umpire move, possibly after the play.

Need to describe motions: batter swings, ball hit, runner runs, umpire makes a call (arm movement), catcher reacts. Spatial relationships: batter in front of home plate, umpire behind, pitcher on mound. Background has field, trees, but minimal. Camera perspective: seems like a static or slight following shot, maybe from behind home plate.

Let's structure it:

- Initial scene: Batter (white uniform) stands at home plate, umpire (light blue shirt) and catcher (dark jersey, number 28) behind. Pitcher on mound.
- Then, batter swings, hits the ball. Runner (white uniform) from first base runs towards second.
- Umpire raises arm (signaling out or safe?), catcher steps back.
- Finally, the runner reaches second base, umpire and catcher move positions.

Check for chronological order: action steps in sequence. Mention key motions and positions.

Now, draft:

In a baseball game, a batter in a white uniform stands at home plate while an umpire in a light blue shirt and a catcher in a dark jersey (number 28) stand behind him. The pitcher on the mound throws the ball, prompting the batter to swing and hit it; a runner in a white uniform from first base sprints toward second base. The umpire raises his right arm to signal a play, while the catcher steps backward. Subsequently, the runner reaches second base as the umpire and catcher adjust their positions. The camera remains positioned behind home plate with minimal movement.

Wait, check if the batter's number is mentioned? The rules say exclude named characters or stylistic, but appearance: color, size, orientation. So "white uniform" for batter, "light blue shirt" for umpire, "dark jersey" for catcher. Number 28 is part of appearance. The runner is white uniform too.

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

A batter in a white uniform stands at home plate with an umpire in a light blue shirt and a catcher in a dark jersey (number 28) positioned behind him. The pitcher on the mound throws the ball, causing the batter to swing and make contact; a runner in white uniforms from first base runs toward second base. The umpire raises his arm to signal a call, while the catcher steps back. The runner reaches second base as the umpire and catcher reposition. The camera remains stationary behind home plate.

Wait, the first frame shows the batter, then he swings. The umpire moves—maybe the umpire is signaling. Let's check the video frames:

Frame 0: Batter at home, umpire behind, catcher behind umpire. Pitcher on mound.

Frame 1: Pitcher throws, batter swings (maybe hit?).

Frame 2: Umpire raises arm (maybe signaling out), runner in white (from first?) is running.

Frame 3: Umpire still raises arm, runner continues.

Frame 4: Umpire points, runner heads to second.

Frame 5: Runner is at second base, umpire and catcher move.

So the sequence: batter hits, runner runs to second, umpire signals, they move. The key actions: swing, run, signal, reposition.

Now, make sure chronological: first the batter swings (after pitch), then the runner starts running, then umpire signals, then they move.

So:

A batter in a white uniform swings the bat at home plate as an umpire in a light blue shirt and a catcher in a dark jersey (number 28) stand behind him. The runner in white uniforms from first base sprints toward second base, while the umpire raises his right arm to make a call. The catcher steps back, and the runner reaches second base as the umpire and catcher adjust their positions. The camera remains positioned behind home plate with slight movement.

Wait, need to check the video description. The user provided 5 frames. Let's parse each:

[0] Batter (white uniform) at home plate, umpire (light blue) and catcher (dark, 28) behind. Pitcher on mound.

[1] Batter hits (ball in motion), ump

Solid objects: pitcher (throwing ball), batter (swinging), catcher (catching), umpire (observing) exhibit locomotion and collision-driven motion (ball in flight, swing, catch).

Static background elements (field, trees, sky) show no uniform shifting or fluid motion; no fire, water, or smoke detected.
