A person in a gray shirt and blue jeans holds a gray and white bird on their lap, where scattered seeds lie. The person adjusts the bird with their hands, lifts it slightly, and then uses their fingers to pick up a seed to offer to the bird. The bird remains on the lap throughout the sequence, facing the person. The camera maintains a close-up perspective on the interaction without significant movement.

Discrete solid objects include the person's hands and a bird. The hands move to interact with the bird (petting, adjusting position), while the bird exhibits subtle head and body movements in response to the touch.

No shifting backgrounds or fluid/environmental motion (fire, water, smoke, wind) observed. Static background elements (e.g., yellow container) remain consistent across frames with no uniform displacement.


A child wearing a yellow shirt uses their right hand to trace letters on a worksheet with blue guide lines, moving the hand across the page while the left hand occasionally adjusts the paper's position; the camera maintains a close, slightly shaky top-down view of the writing activity.

A hand (discrete solid object) is moving across the paper, interacting with handwritten text and cartoon illustrations.

No shifting backgrounds or fluid/environmental motion (fire, water, wind) observed; background elements (paper, cartoon illustrations) remain static relative to the frame.


A red table displays a grid of small yellow and white packaged items and a blue cylindrical container on the right. A hand enters from the top right, moves leftward, picks up a gray object from a package, and manipulates it. The camera maintains a top-down perspective with slight shake.

A person's hands manipulate a small card/magazine, including picking it up, aligning, and positioning it relative to the grid of magazines on the table.

The red table surface and static magazine grid remain fixed throughout the video; no fluid motion (fire, water, smoke) or environmental swaying (e.g., wind-blown trees) is observed.


A person in a dark shirt enters from the left, moves toward the right wall, and lifts a white rectangular object upward to position against the wall, adjusting its placement. The background includes exposed ceiling pipes and cabinets, but the focus centers on the individual's actions. The camera remains stationary throughout, capturing the scene from a fixed angle with no significant movement.

A person enters the frame, walks toward the ceiling, and lifts/positions a rectangular object (likely a board or panel) against the ceiling structure.

Background elements (ceiling beams, walls, windows) remain static with no uniform shifting or fluid motion; no fire, water, smoke, or wind evident.


A young child with curly hair and a dark blue striped shirt sits at a table, holding a small object with both hands and moving it slightly as they look around. In the background, a person in a striped shirt moves their hands near a table with orange and white balloons and a potted plant. The camera remains stationary, capturing the scene from a fixed angle.

The child is holding and manipulating an object (likely a toy) with hand movements, and the head is slightly moving.

No shifting background or fluid/environmental motion observed. The wall, table, and vase remain static throughout the frames.


A young toddler in a striped shirt sits at a restaurant booth, initially holding a sippy cup and facing away from the camera. The child then turns to face the camera, lifting the cup and looking directly at the lens. Other diners are visible in the background, seated in wooden booths. The camera remains stationary with a slight low angle perspective.

Baby (discrete object) moves head and hands; adult hand moves bottle. All motions are localized, intentional movements of solid objects without environmental influence.

Background shows static restaurant interior with people, wall mural, and plants. No fire, water, smoke, or wind observed; background elements remain consistent without uniform shifting.


A shirtless man in white pants sits on a chair, then stands and executes a rapid kick or martial arts motion. The camera remains stationary with a slight shake throughout.

A shirtless person moves discretely (adjusting pants, standing/sitting shifts) as a solid object due to self-driven locomotion.

Static background elements (cabinet, wall, bags) show no uniform shifting; no fire, water, or wind motion detected.


A person in a red shirt and dark pants stands in front of illuminated city buildings at night. They raise their right arm, jump upward with both arms extended, land, and then move leftward, exiting the frame. The camera remains stationary throughout.

A single person in red clothing performs dynamic movements (spinning, jumping), exhibiting clear locomotion and physical interaction with the environment.

The cityscape background with illuminated buildings remains consistently positioned across frames, showing no uniform shifting. No fluid or environmental motion (fire, water, wind) is observable.


RAW CAPTION: Got it, let's tackle this video caption. First, identify the main subjects. There's a catcher (black jersey with 25, helmet) in the foreground, a pitcher (blue jersey) in the middle distance, and other players in the background.

Chronological order: The video starts with the pitcher in a pitching stance. Then, the catcher is in position. The pitcher throws the ball, which moves towards the catcher. The catcher then extends his glove to catch the ball.

Appearance: Catcher is black shirt, white pants, helmet, number 25. Pitcher is blue shirt, white pants. Others in background: red and white jerseys.

Spatial relationships: Catcher is in front, pitcher is behind the catcher (or slightly in front of the pitcher's mound), other players are in the background, spaced out.

Camera perspective: It's a stationary shot, probably from behind the catcher looking towards the pitcher. No movement mentioned, so camera is fixed.

Background: Baseball field, fence, trees, but minimal description.

Now, structure the caption. Start with the sequence: pitcher throws, catcher catches. Mention appearances briefly.

Check rules: focus on motion and behavior in order.

So: A baseball pitcher in a blue jersey throws a ball toward a catcher wearing a black jersey with the number 25 and a helmet, who extends his glove to catch the ball. The pitcher is positioned in front of the catcher, with other players in the background. The camera remains stationary, capturing the action from behind the catcher.

Wait, need to make sure chronological order. First, pitcher is in position, throws, then catcher reacts.

Original video: [0.0] pitcher has ball, [1.0] catcher moves, [2.0] catcher in position, [3.0] pitcher throws, [4.0] catcher dives? Wait, no. Let's check the frames:

Frame 0: Pitcher is in position, ball is in the air (maybe just released). Catcher is behind the plate, arm up.

Frame 1: Catcher has ball, maybe just caught? Wait, no. Wait, the first frame shows pitcher with ball up, then in frame 1, catcher is lowering arm, maybe the ball is thrown. Wait, the movement: the pitcher throws the ball, then the catcher moves to catch it.

Wait, the description:

At [0.0], the pitcher (blue) is in mid-throw, ball is above his head. The catcher (black 25) is in a stance, glove up.

Then, as the ball is thrown (maybe around frame 3), the pitcher is running towards the plate (maybe a wild pitch, but in the video, the catcher moves to catch).

Wait, the key actions: pitcher throws ball, catcher extends glove to catch.

So the chronological order:

1. Pitcher stands in position, ball is held.

2. Pitcher throws the ball.

3. Catcher moves to catch the ball, extends glove.

So the caption should describe that sequence.

Let's write:

A pitcher in a blue jersey throws a baseball toward a catcher wearing a black jersey with the number 25 and a helmet. The catcher extends his glove to catch the ball while standing in front of the pitcher. Other players in red and white uniforms are visible in the background. The camera remains stationary, capturing the action from behind the catcher.

Wait, need to check if "standing in front of the pitcher" is correct. In baseball, the catcher is behind home plate, pitcher is in front of home plate. So the catcher is in front of the pitcher? No, the pitcher is on the mound, catcher is behind home plate. So the pitcher is in front of the catcher's position? Wait, no: the pitcher is at the pitcher's mound, which is in front of home plate. The catcher is at home plate, so the pitcher is in front of the catcher? No, the catcher is behind home plate, pitcher is at the mound, so the pitcher is in front of the catcher. Wait, the catcher is behind home plate, the pitcher is in front of home plate (at the mound), so the pitcher is closer to the plate than the catcher? No, the mound is about 60 feet from home plate. So the pitcher is at the mound (front of the plate), catcher is at home plate (behind the plate). So the pitcher is in front of the catcher.

Wait, in the video, the catcher is the one in the foreground with the helmet and number 25. So the catcher is closer to the camera. The pitcher is further back, so the pitcher is behind the catcher (from the camera's perspective). Wait, camera is behind the catcher, looking

The pitcher (in black) moves to throw a baseball, which is tracked toward the batter (in blue). The batter steps into position, and other players remain stationary.

The background (fence, trees, sky) is static with no shifting or environmental motion. No fire, water, smoke, or wind effects are visible.


RAW CAPTION: Got it, let's tackle this. First, I need to describe the video in chronological order. The video has two scenes. The first scene (0.0s) shows a street with a person in a blue shirt and jeans sitting on a chair, maybe a shoe shiner? There's a person in a white shirt standing next to them. The second scene (1.4s) shifts to a close-up of a person polishing a shoe with a cloth. Then (2.5s-3.6s) it's a close-up of the shoe polisher's hand and the shoe. Then (4.7s) there's a still image of a boy in a costume walking past a brick wall. Wait, the problem says to focus on motion and behavior of main subjects. So the first part is the street scene: a person sitting on a chair (shoe shiner), another standing. Then the scene changes to close-up of shoe polishing. Then the still image. But the user says "chronological paragraph describing the provided video". So let's break down each segment.

First frame: A person in a blue shirt and jeans sits on a chair on a street, another person in a white shirt stands nearby. Second frame: Close-up of a person polishing a shoe with a cloth, the shoe is black. Third frame: Hand holding a cloth polishing a shoe. Fourth frame: Hand still polishing. Fifth frame: A still image of a boy in historical costume (tricorn hat, vest, purple pants) walking past a brick wall. Wait, the user says "video", so maybe the transition is from video to image. But the caption needs to be about the motion.

Wait, the rules say "focus primarily on the motion and behavior of main subjects in chronological order". So the video starts with a street scene: a person sitting (shoe shiner) and another standing. Then cuts to close-up of shoe polishing. Then the video might have a still image at the end. So in the description, we need to note the sequence: first scene (street), then close-up of shoe polishing, then the still image.

Wait, the video is split into segments. Let's check the timestamps:

[0.0] - street scene: person in blue shirt/jeans sitting on chair, person in white shirt standing next to them.

[1.4] - close-up of person polishing a black shoe with a cloth.

[2.5] - closer view of hand polishing shoe.

[3.6] - hand polishing shoe, still close-up.

[4.7] - still image of boy in costume walking past brick wall.

But the video is presented as a sequence of clips. So the caption needs to describe each part in order.

Start with first scene: two people on a street (one sitting on a chair, another standing). Then cut to close-up of shoe polishing, where a person's hands use a cloth on a black shoe. Then the scene shifts to a still image of a boy in a historical costume walking.

Wait, but the rules say "exclude text recognition, named characters, or stylistic analysis". So don't mention "shoe shiner" unless it's observable. The first scene: person sitting (blue shirt, jeans), person standing (white shirt). Then the next part is close-up of hands polishing a black shoe. Then the still image of a boy in a costume (tricorn hat, vest, purple pants) walking.

So the caption should be in chronological order. Let's structure it:

The video opens with a street scene where a person in a blue shirt and jeans sits on a chair while another individual in a white shirt stands nearby. It transitions to a close-up of hands polishing a black shoe with a cloth. Subsequently, the video displays a still image of a boy in a historical costume (tricorn hat, vest, purple pants) walking past a brick wall.

Wait, but the problem says "motion and behavior of main subjects". The still image is not motion, but the video includes it as part of the sequence. The main motion is the first two parts (street scene with people, shoe polishing), then the still image.

Wait, the first clip is the street scene with the two people. Then the video shows close-up of shoe polishing (motion: hands polishing shoe). Then the next frame is the still image. So the description should note the sequence.

Also, "briefly describe their appearance and number". In first scene: two people (one sitting, one standing). Then in the shoe polishing: a person's hands (color not specified except maybe the shirt is light, but the clip is blurry). Wait, the second scene (1.4s) shows a person in a white shirt (same as the standing person?) polishing a black shoe. So in the close-up, it's a person (white shirt)

A shoe shiner is using a cloth to polish a shoe, with the hand and cloth moving in contact with the shoe due to applied force. The customer's leg may be slightly moving as the shoe is being polished.

The background in the modern shoe-shining scene is static (shop interior), but there is minor ambient motion from pedestrians walking. No fire, water, smoke, or wind. The old street scene also has moving pedestrians but is a brief segment and not dominant.


A person in a dark shirt repeatedly tosses a yellow object, moving left and right in front of a shelf with trophies and red columns. The camera remains static throughout the sequence.

A person (man in black shirt) is moving and throwing a green ball, which is also moving due to the throw and catch.

The background (trophies, red curtains, banner) is stationary and shows no fluid motion (fire, water, wind).


Two hands are visible, one holding a smartphone with a purple screen and the other holding a card with a blue design; the hands move the card toward the phone, adjust their positions, and then withdraw, leaving the phone against a plain gray background. The camera maintains a static close-up perspective.

Hands and a purple object (likely a phone or case) are being manipulated by the hands.

Background is static and plain. No signs of fire, water, smoke, or wind.


A person in black tactical gear crouches near green and white inflatable bunkers on a dirt field, then stands and runs leftward across the area while holding a long object. Another individual in similar gear is visible in the background near additional inflatable structures. The camera follows the primary subject with slight movement, capturing their progression through the obstacle course.

A person in black clothing moves across the frame, carrying a weapon. Another individual is visible in the background. Both exhibit locomotion (walking, turning) due to physical movement.

No shifting background elements (fence, ground, inflatables remain fixed). No fire, water, smoke, or wind-driven motion observed.


A person in a red shirt massages the face of another individual lying on a bed covered with a green blanket.

The therapist's hands are moving the patient's face, demonstrating discrete object motion due to manual therapy.

The background (room, floor, chairs) is static with no shifting or fluid motion. No fire, water, smoke, or wind visible.


A blond-haired person in a green shirt and black pants reclines on a couch, holding and moving a remote control while looking to the side. The camera cuts to another person in a black hoodie seated at a desk with books and a laptop, reading a book. The camera remains static in both scenes.

The person (wearing a green shirt) moves from the couch, picks up a remote control, and walks toward the bookshelf, exhibiting clear locomotion and physical interaction with objects.

No shifting background elements; no fire, water, smoke, or wind observed. Static walls and furniture remain consistent without environmental fluid motion.


A person wearing a white shirt with blue striped suspenders and a dark necktie manipulates the tie to form a double knot. They loop the tie around their neck, pull the ends through the loop, and adjust the knot's tightness. The camera remains stationary, focusing on the upper body against a plain background.

A person's hands (discrete, solid objects) manipulate a necktie through controlled movements: crossing the tie ends, forming loops, and tightening. The tie itself is a solid object moving in response to the hands.

The background is a solid, uniform color with no visible environmental motion (e.g., no fire, water, smoke, or wind). Static background elements (e.g., wall) remain fixed without shifting.


A silhouetted figure in the center of a gymnasium extends arms and rotates in place, while another silhouetted figure on the right rises from a seated position to a standing stance. The camera maintains a fixed perspective with slight vibration throughout.

Two distinct human figures are moving within the scene; one is walking toward the center-left, while another is positioned in the background near the right side, exhibiting locomotive motion.

The background elements (walls, ceiling, lighting) remain static across frames with no uniform shifting, and there are no fluid or gaseous environmental motions (fire, water, smoke, wind) present.


RAW CAPTION: Got it, let's tackle this. First, the video shows a person in a red jacket playing a saxophone. The person is in a tunnel, maybe. Let's check the frames. The person is lying down? Wait, no, the video might be upside down. Wait, the first frame: the person is in a red jacket, playing saxophone, in a tunnel. The background has a blue wall and a window with light. Then, over the frames, the person is moving slightly, maybe? Wait, the action: the person is playing the saxophone. Let's describe chronologically.

Main subject: one person in red jacket, wearing a hat, playing a saxophone. Orientation: the video is rotated, maybe, so the person is lying on their side? Wait, looking at the frames, the person is in a tunnel, wearing red, playing sax. The sax is golden. Background: tunnel with blue and white walls, maybe a window. The person's position: first frame, then moving? Wait, the frames are sequential. Let's see: from 0 to 5 seconds, the person is playing, maybe shifting slightly. The saxophone is held to the mouth, playing.

Appearance: person in red jacket, dark pants, light-colored hat (maybe beanie), playing golden saxophone. Number: one person.

Spatial: the person is in a tunnel, with the tunnel walls (blue and white) visible. The person is positioned against the wall? Maybe. The camera is probably looking from an angle, maybe from below? Wait, the video is upside down? Because the first frame shows the person with head up, but the description says "lying down"? Wait, no, the video is rotated. Wait, the user didn't say it's rotated, but the frames show the person as if the video is flipped. Wait, the problem is to describe the motion as per the video. Let's check the frames:

In the video, the person is wearing a red jacket, playing a saxophone, and the background is a tunnel. The person's position: from the frames, the person is moving slightly, maybe turning their head or the saxophone. The background is a tunnel with a blue wall on one side and a white wall, and a window letting light in.

Chronological order: The person in red jacket and hat plays the saxophone, maintaining position in the tunnel, with slight movements of the body as they play. The saxophone is golden, held to their mouth.

Camera perspective: The camera is fixed, but the video might be rotated (since the person is in a way that's not upright). Wait, the first frame: the person is on the right, head up, playing. The next frames show the person moving slightly left, maybe. Wait, no, the frames show the person's position changing a bit. The camera is static but the subject is moving. Wait, the description says "briefly describe their appearance and number (color, size, orientation)". The person is wearing red jacket, dark pants, light-colored hat. Orientation: the person is standing in the tunnel, playing the saxophone.

Wait, maybe the video is upside down? Because the person's head is at the top in the first frame, but the description says "lying down". Wait, the user's video description might have a rotation. But as an expert captioner, we have to describe what's in the video. Let's think again.

The video shows a single person wearing a red jacket, playing a saxophone. The person is in a tunnel with blue and white walls. The person is moving slightly as they play, perhaps shifting their position. The camera is stationary, capturing the person from a low angle, looking up at them. The background is the tunnel, which is minimal. The person's orientation: they are upright, wearing a hat, red jacket.

Wait, let's check the frames. Frame 0: person in red jacket, saxophone, tunnel. Frame 1: similar, maybe the person's head is slightly tilted. Frame 2: same. Frame 3: person moving left a bit. Frame 4: person moving more left. Frame 5: person moving further left, maybe. So the person is playing the saxophone and moving slightly left in the frame over the 5 seconds.

So chronological: A person in a red jacket and hat plays a golden saxophone, positioned in a tunnel with blue and white walls. The person remains mostly upright but shifts position slightly leftward while playing. The camera maintains a fixed perspective, capturing the scene from a low angle.

Wait, the rules: focus on motion and behavior in chronological order. So the main action is playing the saxophone, and the person shifts position. Appearance: one person, red jacket, hat, saxophone. Spatial: in the tunnel, walls. Background minimal. Camera

RAW CAPTION: Okay, I need to generate a concise caption for this video. Let me watch the video first. There's a sailboat with red and white sails on the water. The video starts with the boat moving, and then another yellow sailboat comes into view from the left. The first boat is red and white, maybe with some flags? The camera seems to follow the boats as they sail. The background has a city with tall buildings, but I should keep that minimal. The main focus is on the boats moving. Let me check the rules. Need to describe the motion in chronological order. First, the red and white sailboat is moving, then the yellow one appears from the left. The camera might be panning to follow them. The caption should mention the number of boats, their colors, positions relative to each other. Also, camera movement. The video is a bit grainy, but the key points are the two sailboats. Let me structure it: start with the first boat, then the second entering, their movement, then the camera's perspective. Avoid background details unless essential. The background has buildings but maybe just mention the cityscape briefly. The caption should end with camera movement. Let me see the examples. The output format is a paragraph inside the tags. Let me draft: "Two sailboats navigate a body of water; a red-and-white sailboat leads initially, followed by a yellow sailboat emerging from the left. Both vessels move forward with their sails fully deployed, maintaining a steady course. The camera tracks their progress with a slight pan left to follow the yellow boat’s approach." Wait, check if the order is correct. The video starts with the red and white boat, then the yellow appears later. So chronological: first the red and white is seen, then the yellow comes into view. The camera is moving left to follow the yellow. Also, mention the spatial relationship: yellow appears to the left of the red boat. Wait, the first boat is red and white, then the yellow comes from the left. So as the video progresses, the yellow boat enters from the left. So the main subjects are two sailboats. Let me rephrase: "A red-and-white sailboat moves across the water, with a yellow sailboat appearing from the left and joining it. Both sailboats advance forward, their sails fully extended, as the camera pans slightly left to follow the yellow boat’s movement. Background buildings remain distant and static." Hmm, maybe "two sailboats" in the beginning. Let me check the rules again. They say "briefly describe their appearance and number (color, size, orientation)". So "two sailboats: a red-and-white one and a yellow one". Also, spatial: the yellow appears to the left of the red. But maybe "followed by a yellow sailboat emerging from the left". The camera movement is "pan left" to follow the yellow. The background is minimal, so just mention the cityscape in the distance. The caption should be concise. Let me try: "A red-and-white sailboat sails across the water, with a yellow sailboat entering from the left and moving alongside. Both vessels maintain steady motion with sails deployed, as the camera pans left to track the yellow boat's approach. Background buildings remain static." Wait, but in the video, the yellow boat comes from the left and then they move together. The original video shows the red and white first, then yellow appears from left. So the chronology is first red and white, then yellow enters. So the caption should start with that. Also, the camera movement: in the video, the camera seems to pan left as the yellow boat comes into view. The output needs to mention camera perspective and movement at the end. So maybe: "A red-and-white sailboat moves across the water, followed by a yellow sailboat emerging from the left. Both vessels sail forward with sails fully deployed, their relative positions shifting as the camera pans left to track the yellow boat’s movement." That's concise. Check if "sailing" or "moving" is correct. The boats are moving forward. Also, mention the number: two sailboats. Maybe "Two sailboats: a red-and-white vessel and a yellow one. The red-and-white leads initially, with the yellow approaching from the left. Both advance steadily as the camera pans left to follow the yellow boat." Hmm, but the caption needs to be chronological. Start with the red and white, then the yellow comes. So: "A red-and-white sailboat navigates the water, followed by a yellow sailboat emerging from the left and moving alongside. Both sailboats maintain a steady course with sails deployed, as the camera pans left to track their progress." That works. Check if "moving alongside" is correct. Maybe "moving in parallel" or "following". The original video shows them sailing together after the yellow appears. The

Two sailboats are moving across the water; their motion is driven by wind on the sails and the water's resistance, representing discrete object physics.

The background buildings are static, indicating no camera motion. The water shows gentle wave motion, but it is not dominant as the sailboats are the main subjects.


A person with short hair and a dark shirt with white sleeves arranges dark red flowers inside an orange pumpkin on a wooden table, adjusting the bouquet with both hands. They then step back, completing the arrangement. Two pumpkins sit on the table; the camera remains stationary, capturing the scene from a fixed frontal perspective.

Discrete objects (people playing musical instruments) exhibit controlled motion consistent with physical interaction (e.g., strumming, gesturing).

The background elements (shelves, fan, wall) show no uniform shifting or fluid motion. No fire, water, or wind effects are visible.


A person wearing a dark shirt with colorful patches sits in an office, holding a clarinet vertically and moving their fingers over the instrument's keys while playing. The background includes a desk with papers and a printer. The camera remains static, capturing the scene from a medium angle with no movement.

A person is actively playing the clarinet, with discrete movements of their hands on the instrument keys and mouthpiece. The motion is localized and intentional, driven by physical manipulation of the instrument.

The background (desk, papers, office items) shows no shifting or uniform motion; no fire, water, smoke, or wind is present. Background elements remain static throughout the clip.


RAW CAPTION: Got it, let's break this down. First, the video starts with a view of a person in a blue shirt and gray shorts walking through a garden path, holding a branch. Then, the scene shifts to two girls: one in a white sleeveless top with dark hair in pigtails, and another in a pink shirt with dark hair. They're near a person in light blue shorts, and the girl in white is reaching towards something on the ground. The camera moves around them, showing their interactions. Then it focuses on the man in the blue shirt looking at something in his hands. The background has greenery and trees. Need to describe in chronological order, motions, appearances. Let's structure it: start with the initial scene, then the two girls, their actions, then the man. Mention spatial relationships—like the girls are near the man, the man is in front of the girls maybe? Wait, in the frames, the first frame is the man walking, then the next shows the two girls and the man. So the man is a main subject. Let's outline:

1. Initial scene: A man in a light blue shirt and gray shorts walks through a garden path, holding a branch. He is followed by a group of people in the background. The camera moves to focus on two children: a girl in a white sleeveless top with dark hair in pigtails and another girl in a pink shirt with dark hair. They stand near the man, with the girl in white reaching toward the ground.

2. Then, the girl in white is seen holding something, and the girl in pink stands beside her. The man is partially visible behind them. The camera shifts to show the man in the light blue shirt looking down at an object in his hands.

3. The background includes green foliage and trees, but minimal description. The camera movement is shifting between the subjects, with slight pans.

Wait, need to be concise. Let's check the rules: chronological, motions, appearance, spatial, camera. Let's write a paragraph:

The video opens with a man in a light blue shirt and gray shorts walking through a garden path, holding a branch. He is followed by a group of people in the background. The camera then shifts to two children: a girl in a white sleeveless top with dark hair in pigtails and another girl in a pink shirt with dark hair. They stand near the man, with the girl in white reaching toward the ground. The camera focuses on the girl in white as she picks up an object, while the girl in pink stands beside her. The scene then shows the man in the light blue shirt looking down at an object in his hands. The camera moves around the subjects with slight pans, maintaining a ground-level perspective.

Wait, but need to be more concise. Let's check the frames:

Frame 0: Man in blue shirt, gray shorts, walking, holding branch. Background: garden, trees, other people.

Frame 1: Girls (white top, pink shirt) with man in gray shorts. Girl in white is reaching down, girl in pink standing next to her.

Frame 2: Same as frame 1 but closer, girl in white is picking something up.

Frame 3: Girl in white (back view), girl in pink, man in gray shorts.

Frame 4: Man in blue shirt, looking at something in his hands.

So chronological order: man walking (initial), then focus on two girls interacting with something on ground, then the man looking at his hands.

So the caption should start with the man walking, then the girls, their actions, then the man's action.

Let's draft:

A man in a light blue shirt and gray shorts walks along a garden path, holding a branch. The camera shifts to two girls: one in a white sleeveless top with dark hair in pigtails, the other in a pink shirt with dark hair, standing near the man. The girl in white reaches toward the ground, then picks up an object. The camera then focuses on the man, who looks down at an object in his hands. The background includes green foliage and trees. The camera moves with slight pans between the subjects.

Wait, need to check rule f: exclude text recognition, etc. Also, rule a: motion and behavior in chronological order.

Another version:

The video begins with a man in a light blue shirt and gray shorts walking through a garden, holding a branch. The camera then shows two girls: a girl in a white sleeveless top with dark hair in pigtails and another in a pink shirt with dark hair, standing close to the man. The girl in white reaches toward the ground and picks up an object. The camera shifts to focus on the man as he looks at an object in his hands. The background consists of green plants and trees.

Wait, but the first frame is the man walking, then the

The adult and children are walking along a path; the adult points at trees, and the children interact with each other and the environment.

The background (trees, ground) is static with minimal wind effects; no fire, water, or significant environmental fluid motion.


Three people (two children and one adult) jump and bounce on a blue trampoline with yellow borders. The adult, wearing a light-colored top, stands between the children, who wear dark clothing, as they move up and down rhythmically. The camera, positioned at a slight angle, captures their motion from a fixed perspective with minimal background details.

Three children (discrete solid objects) are moving across the blue mat area, exhibiting locomotion (walking, turning, holding hands) as the primary physical action.

The static background elements (green walls, yellow borders, colorful murals) remain uniformly stable across frames; no fluid motion (fire, water, smoke) or significant environmental effects like wind are present.


A person wearing a white V-neck shirt adjusts a pair of glasses, holding them with both hands before positioning them over their eyes. The individual is seated in front of a door and a bed with a blue blanket. The camera remains stationary throughout.

A person is making discrete hand movements (adjusting glasses) and gesturing with their hands. The motion is localized to the person's hands and upper body.

Background elements (door, bed, blanket) are stationary across frames. No fluid/environmental motion (fire, water, smoke, wind) detected.


RAW CAPTION: Got it, let's tackle this captioning task. First, I need to look at the video frames. The main subject is a person. Let's see the sequence:

Frame 0: Person is crouched on the floor, holding a large sheet. The room has a ladder, a wall with gray and beige sections, a window.

Frame 1: Person is on the ladder, starting to put up the sheet. The sheet is white, maybe wallpaper? They're climbing the ladder.

Frame 2: Person is on the ladder, placing the sheet higher up. They're adjusting it.

Frame 3: Person is still on the ladder, smoothing or aligning the sheet. The sheet is being applied to the wall.

Frame 4: Person descends the ladder, now on the floor, holding the sheet. Maybe they're adjusting or stepping down.

Frame 5: Person is standing on the ladder again, continuing the work. The sheet is up on the wall.

Wait, need to check the actual frames. The user provided 5 frames (0 to 5). Let's list each frame's action:

0: Person crouched, holding a large white sheet (wallpaper maybe) on the floor.

1: Person climbs the ladder (silver, blue steps) to put the sheet on the wall.

2: Person is on the ladder, adjusting the sheet (up towards the top of the wall).

3: Person steps down from ladder (now on floor) while holding the sheet, possibly adjusting lower part.

4: Person climbs the ladder again, continuing to apply the sheet.

5: Person is on the ladder, working on the sheet.

Wait, the frames are 0.0, 0.3, 1.4, 2.5, 3.6, 4.7. So frame 0 is start, then 0.3, 1.4, etc. Let's see the actions:

At frame 0: Person is crouched on floor, holding large white sheet. Ladder is in front of the wall (which has wooden strips and gray paint).

Frame 0.3: Person climbs ladder to put sheet on wall.

Frame 1.4: Person is on ladder, applying sheet to the upper part of the wall (which is gray texture).

Frame 2.5: Person adjusts the sheet, now positioned higher.

Frame 3.6: Person steps down from ladder, now on floor, holding the sheet.

Frame 4.7: Person climbs ladder again, continuing the work.

Wait, the description in the user's input: "a person in a striped shirt and light shorts climbs a ladder, positions, and adjusts a large white sheet on a wall with gray textured surface and wooden strips."

Need to capture the sequence: starting on floor, climbs ladder, applies sheet, adjusts, steps down, climbs again.

Appearance: person in striped shirt (dark and light stripes), light shorts (beige or khaki), medium size.

Spatial: ladder is in front of the wall, window is to the left of the wall.

Background: room with gray wall, wooden strips (horizontal), window with black frame.

But the rules say to keep background minimal unless essential. So maybe mention the wall (gray texture, wooden strips) is where the sheet is applied.

Chronological order:

- Person is crouched on floor holding sheet.

- Climbs ladder to apply sheet to wall.

- Adjusts sheet position on the wall.

- Steps down from ladder.

- Re-climbs ladder to continue adjustment.

Now, the caption should be concise, chronological.

Let's structure:

A person in a striped shirt and light shorts crouches on the floor holding a large white sheet. They climb a silver ladder with blue steps, positioning the sheet on a gray textured wall with horizontal wooden strips. The person adjusts the sheet to the upper wall section, then steps down from the ladder, holding the sheet. Afterward, they climb the ladder again to continue aligning the sheet.

Check rules:

a) Motion and behavior chronological: yes.

b) Appearance: striped shirt, light shorts, large white sheet.

c) Spatial: ladder in front of wall, window left (but maybe minimal, so maybe not necessary unless essential. The wall has gray texture and wooden strips, which is part of the action.)

d) Camera perspective: it's a static shot, no movement described.

e) Background minimal: the wall's texture and strips are necessary to understand where the sheet is applied.

f) Exclude text, named characters: okay.

g) Internal thinking, no output.

Now, write it concisely.

Let's draft:

A person in a striped shirt and light shorts crouches on the floor holding a large white sheet. They climb a silver ladder with blue steps to position the sheet on a gray textured wall with horizontal wooden

A person is actively moving: climbing a ladder, adjusting position, and performing physical work on the wall. The motion is discrete and solid, driven by human locomotion and task execution.

The static background elements (wall, window frame, ladder) remain fixed across frames with no uniform shifting or fluid/environmental motion (fire, water, smoke, wind).


RAW CAPTION: Okay, let's tackle this video captioning task. First, I need to understand what the user is asking for. They provided a video description with several frames, and my job is to generate a concise, chronological paragraph following specific rules.

Looking at the rules, the main points are to focus on motion and behavior in order, describe appearance and number, mention spatial relationships if relevant, conclude with camera perspective and movement, keep background minimal, exclude text recognition, named characters, or stylistic analysis. The output must be in a specific format without any reasoning.

The video starts with a black screen with the text "Your hair will love you" and sparkles on the right. But rule g says to exclude text recognition, so I shouldn't mention the text. Next, the scene transitions to a woman with long brown hair in a gray top against a white background. She turns her head and body to the side. Then there's a transition with black and white squares showing hair products and a website.

Wait, the user's rules say to exclude text recognition, so the website and product labels shouldn't be included. The main subjects here are the woman. Let me check the frames again. The first frame is black with text and sparkles. Second frame same as first but maybe the sparkles are less. Third frame is the woman appearing. Fourth frame she turns her head to the left. Fifth frame she turns her body to the side. Then the transition to black and white squares, which includes products, but since we can't mention text, maybe just note the transition.

Wait, the problem says to focus on the motion and behavior. So the woman's actions: she's standing against a white background, then turns her head to the left, then turns her body to the right. Then there's a transition with geometric shapes (black and white squares) that show product packaging, but since text isn't to be included, perhaps just describe the transition as black and white squares moving.

The camera movement: when the woman is shown, the camera is static, then during the transition, there's a shift to the geometric squares. The background changes from white to black and white squares.

Wait, the rules say to keep background descriptions minimal unless essential. The white background is where the woman is standing, so maybe it's essential. The geometric transition is part of the scene change.

Wait, the user says to mention spatial relationships if relevant. The woman is in front of a white background. When she turns, she's moving from facing forward to turning her head left, then body to the side.

So putting it all together:

Starts with a black screen with sparkles (but exclude text), then transitions to a woman with long brown hair in a gray top. She turns her head to the left, then turns her body to the right. The background is white. Then the video transitions to a split-screen with black and white geometric shapes (squares) that move. The camera remains static during the woman's actions but shifts to a geometric transition.

Wait, but rule d says to conclude with camera perspective and movement. So after the woman's movements, the camera shows the geometric transition. So the camera movement during the woman's scenes is static, then the transition to geometric shapes is a cut or transition.

Wait, the video frames: frame 0-1 is black with text and sparkles. Frame 2 is the woman, frame 3-4 she turns, then frame 5 is the transition to the squares. So the sequence is:

1. Black background with sparkles (but exclude text, so maybe just say black background with sparkles moving)
2. Woman with long brown hair appears against white background
3. She turns her head left, then body to the side
4. Transition to black and white squares moving

But need to describe motion and behavior chronologically.

Wait, the first part of the video: [0.0] starts with black background, sparkles on the right. Then [1.4] same, but maybe the sparkles are less. Then [2.5] the woman appears. [3.6] she turns her head left, [4.7] turns body to side, [5.0] transition to black and white squares.

But according to the user's input, the frames are:

[0.0] black with text and sparkles

[1.4] same as [0.0] (maybe sparkles fade)

[2.5] woman in gray top appears

[3.6] woman turns head left

[4.7] woman turns body to side

[5.0] transition to black/white squares with products

But the rules say to exclude text and named characters, so the text and products are out.

So the main subject is the woman. Her actions: appears against white background, turns head left, turns body to

The woman (a discrete solid object) is moving: turning and smiling, with her hair moving as a result of her body movement.

No ambient environmental motion (fire, water, smoke, wind) detected. Backgrounds (white wall, tiled wall) are static, with no shifting or fluid motion.


A child with short hair appears in a webcam feed, initially smiling with mouth open; they turn their head to the right, then to the left, and finally face forward. The child’s ear is visible in later frames. The webcam display remains fixed, with minimal background visible behind the child.

The discrete object is a person whose head and facial expressions change dynamically (smiling, turning head, shifting gaze). This motion is localized to the person's head and face, with clear bounding box tracking.

The background behind the computer screen (cityscape) shows no shifting or fluid environmental motion (e.g., fire, water, smoke). The video is a static recording of a computer screen displaying a chat window.


RAW CAPTION: Got it, let's break this down. The video shows three people by a river. First, I need to describe their actions in order.

Looking at the timestamps:

- At [0.0], there's a person in a green shirt bending down, another in light blue bending, and a third in purple standing with a blue cup.
- As it progresses, the green-shirted person moves, the blue-shirted person continues bending, and the purple one holds the cup.

Main subjects: three people. Their appearance: green shirt (male?), light blue shirt (male?), purple shirt (female?) — but need to mention colors. Spatial: the green is left, blue is middle bending, purple is right standing.

Actions: They're in shallow water near the bank. The green and blue are bending, possibly looking at something in the water or sand. The purple stands holding a blue cup.

Chronology: Start with them near water, green and blue bending, purple holding cup. Then maybe the green moves slightly, blue continues, purple stays.

Background: river, some grass. Minimal description.

Camera perspective: seems like a static shot, maybe slight shake. No movement mentioned, so maybe fixed camera.

Now, structure the caption:

Three people stand in shallow river water near a grassy bank. A person in a green shirt bends forward, another in light blue bends to the right while holding a blue cup, and a third in a purple shirt stands to the right holding a blue cup. The green-shirted individual shifts position slightly, while the light blue-shirted person continues bending, and the purple-shirted person maintains their stance. The camera remains static with a slight shake, capturing the scene from a medium distance.

Wait, need to check chronology. First frame: green, blue, purple. Then the blue and green are bending, purple holding cup. Then in later frames, they move.

Wait, the video is 5 seconds. Let's see:

[0.0] - three people. Green, blue bending, purple standing.

[0.3] - same.

[0.6] - green moves, blue bends more, purple holds cup.

[0.9] - green still bending, blue and purple same.

[1.2] - similar.

[1.5] - maybe the green moves left, blue continues.

So the main actions: the three individuals are at the water's edge. The person in green bends forward, the one in light blue bends to the right (maybe in the water), and the person in purple stands holding a blue cup. Over time, the green-shirted individual shifts their position, the light blue-shirted person continues to bend and interact with the water/sand, while the purple-shirted person holds the cup steadily.

Now, make it concise.

"Three people stand in shallow river water near a grassy bank. A person in a green shirt bends forward, another in light blue bends to the right, and a third in a purple shirt stands holding a blue cup. The green-shirted individual shifts position leftward, the light blue-shirted person continues bending toward the water, and the purple-shirted person maintains their stance holding the cup. The camera remains static with a slight shake, capturing the scene from a medium distance."

Check rules:

a) Motion and behavior chronological: yes, describes actions as they happen.

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

c) Spatial: green left, blue middle, purple right.

d) Camera: static with slight shake.

e) Background minimal: grassy bank mentioned, river is implied.

f) Exclude text, names, etc.: no names, text.

g) Think internally but output caption.

Now, tighten it up:

"Three people stand in shallow river water near a grassy bank. A person in green bends forward, another in light blue bends to the right while holding a blue cup, and a third in purple stands holding a blue cup. The green-shirted individual shifts leftward, the light blue-shirted person continues bending toward the water, and the purple-shirted person maintains their stance. The camera remains static with a slight shake, capturing the scene from a medium distance."

Wait, the blue cup: the purple person holds a blue cup, and the light blue shirted person—does he hold one? In the first frame, the purple person has a blue cup, maybe the light blue person is holding something else? Wait, the video: [0.0] purple person holds a blue cup, the green and blue are bending. Let me check the frames.

The description says: first frame, purple person is holding a blue cup (maybe two cups? Or one). The key is to describe what's visible. Maybe the purple person holds

Three people are visible: one in a blue shirt bending toward the water, one in a green shirt assisting, and one in a purple shirt holding a container. Their movements (bending, reaching, turning) are discrete and driven by intentional physical actions.

The water in the background shows minor ripples, but static elements like the grassy shoreline remain fixed. The water motion is not dominant; it is secondary to human activity.


A pair of hands uses a black file to smooth the corners of a large, clear rectangular ice block, causing ice shavings to scatter; the hands reposition the file to address all edges, then switch to a yellow-handled screwdriver to further refine the surface. The camera maintains close-up shots, shifting angles to capture the filing motion against a dark backdrop.

Hands and a chisel tool interact with a solid ice block, causing discrete chipping and reshaping. The ice block is the main solid object undergoing motion due to tool application.

The dark, fabric-like background shows no uniform shifting or environmental motion (e.g., wind, fluid flow). Melting ice water is a minor byproduct, but the primary motion is not dominated by ambient fluids.


RAW CAPTION: Got it, let's tackle this. First, the video shows a person on stage. They start with a white shirt, black shorts, red tie, and a hat. Wait, the description says in the first frame they have a white shirt, but then as they move, the shirt might change? Wait, the first frame says "white shirt, black shorts, red tie, and a hat." Then in the next frames, they're holding a baton. So the main subject is one person.

Let's break it down chronologically. The video starts with the person standing on a stool (or platform), holding a baton. They raise the baton, then perform gestures—like spinning, throwing, maybe twirling. The background has stage lights (white, blue, red, white) and a banner, but we need to keep background minimal.

So sequence: Person on stage, standing on a stool, holding baton. Moves baton in various motions (raising, extending arms, spinning), maybe some acrobatic moves? Wait, the video shows them standing on a stool, then moving. The stool is a platform.

Appearance: One person, wearing white shirt, black shorts, red tie, hat initially, but maybe the hat comes off? Wait, the first frame has a hat. Then in frame 1.4, maybe the hat is removed? Wait, the problem says "briefly describe their appearance and number (color, size, orientation)." So need to note key details: one person, wearing white shirt, black shorts, red tie, hat.

Spatial relationships: On stage, in front of the banner, under stage lights. But background minimal, so maybe just mention stage.

Camera perspective: Probably static, since it's a stage performance, so likely fixed camera, no movement mentioned.

So the caption should be: A single person, wearing a white shirt, black shorts, red tie, and a hat, stands on a stool on stage. They begin by holding a baton, then raise and extend their arms to manipulate the baton in circular motions. The performer’s movements are dynamic, with the baton spun and twirled in front of them. The camera remains fixed, capturing the performance from a frontal perspective.

Wait, need to check rules: focus on motion and behavior chronologically. Start with initial position, then movements.

Let me structure:

1. Initial state: Person on stool, holding baton, wearing specified clothes.
2. Actions: Raises baton, then moves arms (spinning, throwing, etc.).

Check if the hat is always there? The first frame has a hat, but maybe the video shows them without? The problem says to mention appearance briefly, so list key clothing.

Also, the background has the banner, but rule e says minimal background. So maybe just "on stage" without the banner details.

Camera: no movement mentioned, so "fixed camera" or "stationary."

Let me draft:

A single performer, dressed in a white shirt, black shorts, red tie, and a hat, stands on a stool on stage. They begin holding a baton, then raise their arms to perform dynamic baton movements, spinning and extending the baton in various motions. The camera remains stationary, capturing the performance from a direct frontal view.

Wait, the initial frames show the person with the baton. Let's check the video frames:

[0.0] - standing on stool, holding baton.

[1.4] - raising baton.

[2.5] - spinning or moving baton.

[3.6] - extending arms, baton in motion.

[4.7] - baton in hand, arms out.

So the sequence is: standing, then moving baton up, spinning, moving arms, etc.

So chronologically: The performer, dressed in a white shirt, black shorts, red tie, and hat, stands on a stool. They raise the baton upward, then manipulate it with sweeping motions, extending their arms to twirl and spin the baton.

Need to make sure it's concise.

Final caption should be: A single person in a white shirt, black shorts, red tie, and hat stands on a stool on stage, holding a baton. They raise the baton, then extend their arms to spin and twirl it in circular motions, moving the baton in front of them. The camera remains fixed, capturing the performance from a frontal perspective.

Wait, but the hat might not be on in all frames. The first frame has a hat, but maybe the video shows them without. However, the problem says "briefly describe their appearance" so include initial appearance.

Also, check if the stool is part of the scene—yes, they start on

A single person in dark attire performs controlled arm and body movements consistent with a physical performance (e.g., dance/martial arts), with clear bounding box tracking.

The stage curtain and overhead lights remain stationary throughout; no fluid motion (fire, water, smoke) or wind effects are observed.


A person in a dark jacket and green pants bends over, then kneels on a stone floor while handling wires, with tools like a shovel and bucket visible in the background. The individual, initially standing with an arm raised, shifts to a crouched position near a wooden ladder against the stone wall. The camera transitions from a low-angle view to a top-down perspective, capturing the person's movements amidst the dimly lit, cluttered space. The background remains minimal, emphasizing the stone wall and scattered equipment.

The main discrete object is a person moving by bending down and interacting with the ground or equipment. This motion is due to explicit physical forces (locomotion).

The background consists of rocky walls and a static metal structure. There is no fluid or gaseous motion (fire, water, smoke) and no uniform shifting of the background that would indicate camera motion.


Initially, four people work in a field of dense bushes; one bends over while another stands holding tools, and two others are positioned nearby. The camera then shifts to a close-up of a person pointing at the foliage with their arm extended toward the plants.

Discrete solid objects: multiple people (farmers) bending and moving in the field; a man extending his arm to point at a tree. These motions are driven by human locomotion and deliberate arm movement.

The background trees and field show no significant swaying or fluid motion (e.g., no dominant wind, water, or smoke). Background elements remain stable and static across frames.


A hand guides a bright pink fabric strip through a white sewing machine, adjusting its position to align under the needle. The fabric is steadily moved from left to right through the machine's feed dogs. The camera maintains a static close-up perspective, focusing solely on the sewing process.

A human hand (discrete solid object) actively guiding pink fabric through a sewing machine, causing the fabric to move relative to the machine's needle and feed dog.

Static sewing machine background with no shifting elements; no fire, water, smoke, or wind observed. Red ruler and machine components remain fixed.


tags.  So draft: <caption_output>A pot containing diced pinkish-red ham pieces is shown. A metallic spoon adds more diced ham from above, increasing the pile within the pot. The camera maintains a top-down view with slight movement focusing on the pot's contents.

A metal spoon stirs chopped meat pieces (discrete solid objects) within a pan, demonstrating physical interaction between the spoon and meat.

Background (stove surface, pan) is static with no uniform shifting. Minimal steam rising from meat, which is not dominant environmental motion.


A coffee machine dispenses dark brown coffee into a clear glass positioned on its drip tray. The camera then zooms upward to focus on the machine’s control panel, revealing illuminated buttons and a pressure gauge. Finally, a hand reaches from the right to lift the filled glass from the tray.

A human hand (solid discrete object) enters the frame and interacts with the coffee machine, demonstrating physical movement.

Background elements (coffee machine, containers) are static; no fluid environmental motion (e.g., water flow, fire, smoke) dominates the scene beyond the controlled coffee brewing process.


A bare-chested infant lies on a bed, holding a small colorful toy with both hands and moving it up and down. The baby then releases the toy, shifts their hands, and plays with their feet. The camera remains stationary, capturing the infant's movements from a close-up angle above the bed.

Baby (a person) actively manipulates a bottle with hands and legs, exhibiting deliberate movements like sucking, lifting, and repositioning.

No shifting background elements; curtain, bed, and wall remain static throughout. No fire, water, smoke, or wind observed.


RAW CAPTION: Got it, let's break this down. First, the video starts with a close-up of a hand using a knife on a cutting board with ingredients like a red bell pepper, onion, and a bag of "Worcestershire Sauce." Then it cuts to a pan where five sausages are being browned. The hand uses a green spatula to flip them. The text on screen says to brown five sausages 3-5 minutes each side over medium-high heat. Then it shows a tray with the sausages arranged.

I need to describe the sequence chronologically. Start with the first scene: hand with knife on cutting board with peppers, onion, and the sauce bag. Then the pan with sausages being flipped with a spatula. Then the tray with sausages.

Check the rules: focus on motion and behavior, chronological order. Mention main subjects: hand, knife, sausages, spatula. Describe appearance: red bell pepper, onion, green spatula, sausages (color, size—maybe pinkish, length). Spatial relationships: in the first scene, ingredients on board, sauce bag in background. Then in the pan, sausages in the pan, spatula flipping. Then tray with sausages.

Keep background minimal. Exclude text recognition (the text says "Brown five sausages..." but we don't mention it, just the action).

So the first part: A hand holds a knife on a cutting board with a red bell pepper, white onion, and a bag of sauce. Then cuts to a stovetop pan with five pink sausages, a green spatula flips them. Then shows sausages arranged on a tray.

Need to be concise. Let's structure it:

Initial scene: Close-up of a hand using a knife on a cutting board with vegetables (red bell pepper, white onion) and a sauce bag. Then the scene shifts to a pan where five sausages are being browned; a green spatula flips the sausages. Finally, the pan transitions to a tray holding the cooked sausages.

Check for chronological order. Yes, starts with cutting board, then pan, then tray.

Make sure to mention number: five sausages. Appearance: pink sausages, green spatula.

Camera perspective: first close-up (top-down? or close-up), then top-down on pan, then top-down on tray.

Rules say "Conclude with camera perspective and movement." So need to note the camera movement. The first scene is a close-up (static), then pan to the stovetop, then another close-up? Wait, the video transitions between shots. The first shot is a close-up of the cutting board, then cuts to the pan (so camera moves to pan), then cuts to the tray (camera moves to tray).

But the output should be a paragraph, so describe the sequence.

Let me draft:

A hand uses a knife on a cutting board with a red bell pepper, white onion, and a sauce bag. The scene transitions to a stovetop pan with five pink sausages, where a green spatula flips them. The camera then shows the sausages arranged on a metal tray.

Wait, check the rules: "briefly describe their appearance and number (color, size, orientation)." So for sausages: five, pinkish, lengthwise (assuming they're long).

Also, in the first scene, the ingredients are on the board. The cutting board has ingredients, the sauce bag is partially visible.

Let me check the frames: first frame [0.0] shows hand with knife, cutting board, red pepper, white onion, sauce bag (blue with text). Then [1.0] is a pan with oil, sausages. Wait, the first frame [0.0] has the hand with knife on cutting board, then [1.0] is the pan with oil and the text "Brown five sausages..." but we don't mention text.

So the video starts with a close-up of a hand holding a knife on a cutting board with a red bell pepper, white onion, and a sauce bag. Then cuts to a stovetop pan containing five pink sausages, where a green spatula flips them. The camera then transitions to a tray with the cooked sausages arranged neatly.

Check the rules: Exclude text recognition, so the text on screen isn't mentioned.

Also, spatial relationships: in the first scene, the hand is over the cutting board with the ingredients. In the pan, the sausages are in the pan, being flipped by the spatula.

Now, the caption needs to be a concise paragraph. Let's put it all together.

<caption_output>A

Sausages are discrete solid objects being placed in a pan and flipped using a spatula, exhibiting clear physical interactions (contact, heat transfer).

Background elements (countertop, vegetables) are static; no uniform shifting or fluid/environmental motion (fire, water, wind) detected.


At night on a field near a soccer goal, two individuals interact: the person in a blue shirt runs toward the goal and kicks a ball, while the person in dark clothing runs toward the ball. After the kick, the blue-shirted individual moves to the side, and the dark-clothed individual continues moving. The camera remains stationary throughout, capturing the motion against a dark background.

Two individuals (soccer players) interacting with a ball: one near the goal (goalkeeper) and another attacking. Discrete motion from physical actions (running, kicking, ball handling).

No shifting background elements (goalpost and field remain static), no fire, water, smoke, or wind motion observed. Background does not shift uniformly.


A person’s hand moves in front of a convex mirror, waving and then retracting, while their reflection captures a rusted metal structure with hinges. The hand’s motion alters the reflected image, and the camera remains fixed on the mirror throughout.

The person's hands and body are moving as they wave and make gestures; these are discrete solid objects moving due to voluntary motion.

The background (reflective surface and interior structures) is static; no fluid or environmental motion observed (no fire, water, smoke, wind).


Two people, one in a white shirt with red trim and the other in red, engage in arm wrestling at a table, leaning forward with locked hands. Several onlookers stand and sit around them, observing the contest. The camera remains stationary with minor shake, capturing the interaction from a frontal perspective.

Two individuals engaged in an arm wrestling match, with their arms and upper bodies moving due to physical exertion. Minor movement from spectators in the background.

The background (green wall and stationary spectators) shows no significant shifting or fluid motion. No fire, water, or smoke present.


A female gymnast in a white top and light shorts begins on the floor, then stands, raises both arms overhead, executes a split with one leg extended forward and the other back, and follows with a high kick. The background features stacked mats and equipment, but the camera remains mostly static with slight movement.

A single gymnast performs controlled movements: transitioning from lying down to standing, executing a handstand, and performing leg splits. These are discrete, solid object movements driven by physical forces (muscle control, balance).

The background elements (gym equipment, mats, walls) show no uniform shifting or fluid motion. No fire, water, smoke, or wind is visible.


A pair of hands adjusts a bamboo sushi mat on a green cutting board atop a wooden table, then flips the mat to place a dark green sheet of nori with the rough side facing upward. Sliced vegetables and ingredient plates are visible in the background. The camera remains in a top-down perspective throughout.

Hands are stirring a mixture in a bowl and handling a bamboo mat, placing nori on it. These are discrete solid objects moving due to manual actions.

No fire, water, smoke, or wind observed. Background elements (tables, bottles) are static in each scene with no uniform shifting.


Two shirtless boys wearing blue-and-white checkered swim trunks sit on sandy ground; the younger boy (right) uses both hands to interact with the sand, while the older boy (left) shifts his legs and hand position. The younger boy continues moving his hands in the sand, and the older boy adjusts his posture, remaining seated close to the younger boy. The camera maintains a top-down perspective with slight movement, focusing on the boys’ actions against a plain sandy background.

Two boys (discrete solid objects) are moving their hands and bodies in the sand. The boy on the right digs and manipulates the sand with his hands, while the boy on the left occasionally shifts position and adjusts his hands.

The background (sand) is static with no shifting elements; no fire, water, smoke, or wind motion is present. The sand's displacement is caused by discrete object interactions (boys' hands), not ambient environmental forces.


A boy in a black t-shirt stands in front of an electronic keyboard, pressing keys with his hands while maintaining a stationary posture. His fingers move rhythmically across the keys as he plays. The background includes a bookshelf with books and a desk, but the focus remains on the boy and the keyboard. The camera is static, positioned at eye level with no movement.

The boy (solid object) moves his hands and upper body while playing the keyboard, exhibiting discrete locomotion due to muscle action.

Background elements (bookshelf, computer, desk) are stationary with no shifting or fluid motion (fire, water, smoke, wind) observed.


A person in a red shirt approaches a silver drum set, bending forward and extending their arm toward the camera. Their hand moves into the foreground, obscuring the view of the drum set and creating a blurred motion. The camera remains stationary, focused on the drum set until the person’s motion blocks the shot.

A person in a red shirt moves towards a mechanical device, using their hands to interact with it, and then moves out of the frame causing the scene to darken.

The background is static (mechanical device and dark environment) with no fire, water, smoke, or wind. The only motion is from a person interacting with the device.


In a room with a bed, three individuals are present: one lying prone on the bed, one in a gray shirt kneeling beside the bed interacting with the person's leg, and one in a white shirt standing to the left of the bed. The individual in the gray shirt rhythmically manipulates the leg of the person on the bed, while the person in the white shirt remains stationary. The camera maintains a static perspective throughout the sequence.

The person in the gray shirt is moving the patient's legs with their hands, indicating explicit physical force application. The person in the white shirt is stationary.

Background elements (walls, door) are static with no shifting. No fluid motion (fire, water, smoke, wind) present.


A man wearing a brown hat, dark sunglasses, a black t-shirt, and jeans stands to the left of a window with an air conditioning unit, playing a golden saxophone. His fingers move rhythmically over the instrument's keys while maintaining a steady posture. The camera remains static at eye level, capturing the scene without movement.

A person is actively moving their hands and body while playing a saxophone, representing discrete solid-object motion due to locomotion and physical interaction with the instrument.

The background elements (window, air conditioning unit) show no shifting or environmental fluid motion (fire, water, smoke, wind); all background features remain static across frames.


A person wearing a blue shirt holds a clear plastic bottle with a white cap. The individual uses both hands to grasp and unscrew the cap, twisting it counterclockwise until it is removed. The bottle remains stationary, filled with a clear liquid, while the person’s hands move around the cap. The camera maintains a close-up, steady shot focused on the bottle and the unscrewing action, with minimal background detail visible.

Discrete objects (hands and plastic water bottle) are moving; the hands apply force to unscrew the bottle cap, demonstrating physical interaction.

The background consists of a static blue shirt with no shifting elements or fluid/environmental motion (e.g., fire, water, smoke).


A person wearing orange shorts, white socks, and black sneakers with white details sits on a wooden surface. They use both hands to tie the laces on their left sneaker, then shift to the right sneaker, adjusting the laces. The camera remains fixed in a top-down position throughout the sequence.

A person's legs and hands are moving to tie shoelaces, demonstrating explicit physical locomotion.

The background (wooden surface and window) is static with no shifting or fluid motion (fire, water, smoke, wind).


RAW CAPTION: Got it, let's see. The video starts with a person holding bananas. Wait, no, the first frame shows a person holding a bunch of bananas above a countertop. Then the person moves their hand down, placing a banana on the counter. Wait, the sequence: in frame 0, they're holding bananas. Then frame 1, they place a banana on the counter? Wait, the description says [0.0] shows a bunch of bananas being held, then [1.0] the person moves to place a banana, then [2.0] they have a white banana (maybe a plantain) on the counter. Wait, let's parse the frames:

Frame 0: Person holds a bunch of bananas (yellow, ripe, multiple) above the counter. Background has a fruit basket, containers with veggies.

Frame 1: Person places a banana (white, maybe plantain) on the counter, which was previously not there? Wait, the description says [0.0] shows bananas on counter, then [1.0] the person moves to place a banana. Wait, no: the [0.0] image has a white banana (plantain?) and yellow bananas. Wait, the first frame ([0.0]) shows a person holding a bunch of bananas (so they are in the process of placing or handling them). Then in [1.0], they place a banana on the counter. Wait, the frames:

[0.0] : A person holds a bunch of bananas above the counter. On the counter: two yellow bananas and a white banana (plantain?) are already there. Wait, no, the first frame ([0.0]) says "a bunch of bananas being held", and the counter has "a white banana and two yellow bananas" maybe.

Wait, the instructions: need to describe the motion chronologically. Let's check each frame:

Frame 0: Person holds a bunch of bananas (yellow, ripe) above the wooden countertop.

Frame 1: Person moves hand down, placing a banana on the counter (but the counter already has a white banana and another yellow banana). Wait, no, in [1.0], the action is placing a banana. Wait, the video shows:

At [0.0], person holds bananas. Then at [1.0], the person moves their hand to place a banana on the counter. Wait, but the counter has a white banana and two yellow bananas? Let me re-read the frame descriptions:

<0.3 seconds> [0.0] shows person holding bananas. [0.3] is the first frame.

[0.3] : Person holds bananas (yellow, multiple) above counter.

[1.4] : Person places a banana on the counter (the white banana is already there? Or the white one is placed by the person? Wait, the frame says "a white banana and two yellow bananas" on the counter initially? Wait, the first frame (0.3s) has "a white banana and two yellow bananas" on the counter. Then at 1.4s, person places another banana? Wait, no: the description says:

"at [0.3] person holds bananas (bunch) above counter. [1.4] person places banana on counter. [2.5] person picks up a yellow banana (from counter), then [3.6] person holds a yellow banana, maybe peeling?"

Wait, the actual frame descriptions:

<0.3> : A person holds a bunch of bananas above a wooden countertop with a white banana and two yellow bananas already present.

<1.4> : Person places a banana (white?) on counter? Wait, no, the frame says "the person moves to place a banana on the counter". Wait, no: "at 1.4 seconds, the person places a banana on the counter"—but the counter already has a white banana and two yellow bananas. Wait, maybe the white banana is being moved. Wait, looking at the description:

<1.4> : "Person places a banana on the counter" — but the previous frame shows a white banana and two yellow bananas. Maybe the person is moving the white banana? Wait, no, the next frame <2.5> says "person moves to pick up a yellow banana".

Wait, let's read the frames properly:

<0.3 seconds> : A person is holding a bunch of bananas above a wooden countertop. On the counter, there is one white banana and two yellow bananas, along with containers of chopped vegetables and a fruit basket in the background.

<1.4 seconds> : The person moves their hand downward, placing the held bananas onto the counter, which already has a white banana and two yellow bananas.

<2.5 seconds> : The person uses one hand to

A person is manipulating bananas: peeling, moving, and holding them. These discrete solid objects exhibit motion from explicit physical interactions (peeling, manual handling).

The kitchen background (door, countertop, containers) remains stable with no shifting or fluid environmental motion observed.


Two hands position on a black fabric item laid flat on a wooden surface, then fold the fabric into three equal sections while adjusting the edges. A pink marker is visible as a guide beneath the fabric. The camera maintains a top-down perspective throughout, capturing the hands smoothing and aligning the folded fabric.

Hands and fabric moving as the hands fold the fabric.

No shifting background. No fluid or environmental motion.


A person in dark clothing rinses items in a bathtub using a white handheld showerhead, their hand resting on the tub’s edge as they shift position, the camera following their motion with a slight shake.

A person (wearing dark clothing) is scrubbing the bathtub with a brush. The brush and the person's arms are moving due to physical scrubbing actions.

The background (bathtub, wall, shower curtain, clock) is static with no shifting. There are no fluid or environmental motions (like water, wind) dominating the scene.


RAW CAPTION: Got it, let's break down the video. First, identify the main subjects. There's a group of people around a table. Let's list their actions chronologically.

In the first frame, a man in a black suit with an orange tie is standing behind the table, holding a microphone. Then, a man in a white shirt and black vest is at the table, maybe gesturing or moving his hands. Another man in a white shirt is also at the table, interacting. The person in blue is seated, maybe talking or gesturing.

Looking at the sequence: The man in the black suit (with orange tie) is standing, holding a mic. The man in white vest is moving his arms, maybe explaining something. The other seated people are engaged.

Spatial relationships: The man with the mic is behind the table, the others are seated around it. The blue-shirted person is on one side.

Camera perspective: It seems to be a fixed shot, maybe slight movement? The description says "slight shake" but maybe it's a steady shot. Wait, the user said "conclude with camera perspective and movement". The video frames show a consistent view, so maybe "fixed camera" or "slight movement". But need to check.

Rules: Focus on motion and behavior in order. So start with the man with mic standing, then the man in vest moving his hands (gesturing), the seated individuals interacting.

Now, concisely:

The video shows a group of people seated around a table in a dimly lit room. A man in a black suit with an orange tie stands behind the table, holding a microphone. A man in a white shirt and black vest gestures with his hands while seated at the table, interacting with others. A person in a blue shirt sits to the left of the table, occasionally raising his hand. Another man in a white shirt sits next to the vest-wearer, engaged in conversation. The camera maintains a fixed position, capturing the scene with minimal movement.

Wait, need to check chronological order. Let's see the frames:

Frame 0: Man in black suit (mic), man in vest gesturing, blue-shirted person.

Frame 1: Same, but man in vest moves arms.

Frame 2: Man in vest continues moving.

Frame 3: Man in vest is still moving, maybe leaning.

Frame 4: Man in vest gesturing, blue-shirted person raising hand.

Frame 5: Man in vest moving, blue-shirted person gesturing.

So the main motions: The man in the black suit stands with a mic. The man in the vest moves his hands (gesturing) while seated at the table. The blue-shirted person raises his hand and interacts. Others are seated and engaged.

Also, mention appearance: colors (black suit, orange tie, white vest, blue shirt), number (several people, but main subjects are the ones at the table).

Now, structure the caption:

A group of people gather around a table in a dimly lit room. A man in a black suit with an orange tie stands behind the table, holding a microphone. A man in a white shirt and black vest gestures with his hands while seated at the table, moving his arms repeatedly. A person in a blue shirt sits to the left of the table, raising his hand and gesturing. Another man in a white shirt sits next to the vest-wearer, engaged in conversation. The camera remains fixed, capturing the interaction with minimal movement.

Check if background is minimal. Background has lighting, but focus on people. Don't include "com" text as per rule g (exclude text recognition). So skip that.

Now, concise and chronological. Let's tighten:

In a dimly lit room, a man in a black suit with an orange tie stands behind a table, holding a microphone. Seated around the table, a man in a white shirt and black vest gestures with his hands while conversing. A person in a blue shirt sits to the left, raising and gesturing their hands. Another man in a white shirt interacts nearby. The camera maintains a fixed perspective with slight movement.

Wait, the rules say "conclude with camera perspective and movement". So need to end with that. Let's make sure.

Final draft:

A man in a black suit with an orange tie stands behind a table, holding a microphone. Around the table, a man in a white shirt and black vest gestures repeatedly with his hands, interacting with others. A person in a blue shirt sits to the left, raising their hand and gesturing. Another individual in a white shirt sits nearby, engaged in conversation. The camera remains fixed, capturing the scene with minimal movement.

Check rules:

a) Motion in order: standing man (stationary), vest man gesturing (moving), blue shirt raising hand (moving), others conversing (moving

Discrete solid objects: people (seated individuals in blue/white attire, standing man in suit) moving hands and heads during interaction (e.g., card dealing/gestures).

No shifting background or fluid/environmental motion (fire, water, wind). Background elements (chandeliers, wall patterns) remain static across frames.


A young girl with a ponytail, wearing a white jacket and purple shoes, crouches in a garden bed, extending her hand to smooth the dark soil in front of her. She presses her palm into the earth and moves it across the dirt near green plants, then pulls her hand back. The camera remains close and slightly shaky, focusing on her actions in the garden.

A child (discrete solid object) interacts with soil, moving her hands and body as she touches and manipulates the ground.

Background elements (soil, plants, tree trunk) are static with no significant shifting or fluid/environmental motion (fire, water, wind).


RAW CAPTION: Got it, let's tackle this. First, I need to watch the video frames. The first frame shows a hallway with a person in the background near a door, maybe sitting or leaning. Then a man enters from the left, walks down the hallway, and stops. Wait, the video starts with a view of a hallway. The person in the background—there's a person in dark clothes maybe near the door. Then a man in a gray shirt and dark pants comes in from the left (frame 2), walks through the hallway (frames 2-4), and turns around to face the camera (frame 5).

So chronological: First, the hallway scene with a person in the background. Then a man enters the frame from the left, walks towards the camera, holding a broom? Wait, in frame 2, he's moving into the hallway. Frame 3: he's walking through, frame 4: still walking, frame 5: turns around. Wait, looking at the frames:

Frame 0: hallway, person in dark clothes near a door, maybe sitting on a bench or something.

Frame 1: same as 0? Wait, no, frame 1 shows the person moving—wait, no, the description says [0.3 seconds] to [5.0 seconds]. Wait, the video starts with a still? No, frame 0 is the first, then 1 to 5. Wait, the frames:

<0.3> is the first frame. A hallway. A person in dark clothing is near the far door, maybe sitting. A small table with stuffed toys, pink item on floor. Then at 1.4, a person (man) enters from the left (frame 1), walks down the hallway. At 2.5, he's walking through. At 3.6, he's moving towards the camera. At 4.7, he stops, turns around. Wait, the man is holding a broom? In frame 3, he's carrying a broom. Let's check: in frame 2 (0.3 to 1.4?), no. Wait, the video:

First frame (0.3s): hallway, person in dark clothing standing near the far door (maybe by a bench). Then at 1.4s, a man (gray shirt, dark pants) enters from the left side of the frame, walks through the hallway towards the camera. At 2.5s, he's walking further. At 3.6s, he's moving forward. At 4.7s, he stops, turns around to face the camera, holding a broom.

So the main subject is the man. His appearance: gray short-sleeve shirt, dark pants, holding a broom. He enters from the left, walks down the hallway (towards the camera), then stops and turns to face the camera.

Background: hallway with white doors, a bench with stuffed toys, a pink object on the floor. The person in the background is near the far door—maybe a woman? But the task says to focus on main subjects. The main subject is the man. The person in the background is a secondary element, but the rules say focus on main subjects. So the main subject is the man.

Chronological: The man enters the hallway from the left, walks towards the camera, stops, and turns around.

Spatial relationships: He enters from the left, walks down the hallway (towards the camera), then stops in front of the camera.

Camera perspective: It's a fixed camera, no movement, just a still shot of the hallway.

Now, check the rules:

a) Motion: man enters from left, walks towards camera, stops, turns around.

b) Appearance: gray shirt, dark pants, holding broom.

c) Spatial: enters left, walks towards camera, stops in front.

d) Camera: fixed, no movement.

e) Background minimal: hallway, doors, bench, but minimal.

f) Exclude text, named characters: no names.

So putting it together: A man in a gray shirt and dark pants enters the hallway from the left, walks towards the camera while holding a broom, then stops and turns around to face the camera. The camera remains stationary.

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

At the start, a hallway view with a person near a door. Then a man (gray shirt, dark pants) enters from the left, walks down the hallway toward the camera, holding a broom, stops, and turns to face the camera. The camera stays fixed.

But need to be brief. Focus on motion:

A man in a gray shirt and dark pants walks into the hallway from the left, moves toward the camera while holding a broom, then stops and turns

A man (solid object) moves through the hallway: entering from the left, walking toward the center, turning around, and walking back toward the left. His locomotion is distinct and tracked.

The background (white doors, walls, floor) remains stationary with no shifting or fluid motion. No fire, water, smoke, or wind is present.


A group of dancers, including individuals in red dresses, white shirts, and black suits, move in sync across a stage. They step and gesture while traversing from right to left, with some holding hands. The camera pans left to follow their motion.

Multiple people are dancing and moving across the frame in a coordinated manner. They are solid, distinct objects whose motion is due to their own locomotion.

Background elements (walls, curtains) are static and do not show fluid motion (fire, water, wind). No smoke or other environmental effects.


A person in a light shirt and dark pants adjusts a vertical metal rod on an industrial fixture, manipulating the component with their hands. The fixture, featuring holes and metal arms, is positioned against an orange wall with shelves holding tools. The person remains on the right side of the frame, and the camera maintains a slight shake throughout.

The person's hands and a measuring tool (likely a caliper) are moving to adjust and measure a metal object held in a vise. This motion is due to explicit physical forces applied by the person during the measurement process.

The wooden wall and metal shelves in the background are static with no shifting motion. No fire, water, smoke, or wind is visible; the scene lacks fluid or environmental motion.


A person wearing a white cap and light-colored shirt is visible against a dark nighttime backdrop with distant lights; the individual moves slightly, turning their head and looking around while the camera maintains a close, shaky perspective following their motion.

A single person (wearing a white cap and shirt) exhibits minimal head movements and facial expressions consistent with speaking or gesturing. The subject is a solid, distinct object with motion originating from their own physical actions.

The background consists of dark surroundings with stationary distant lights (e.g., streetlights). No fluid motion (fire, water, smoke) or wind-induced movement (e.g., swaying trees) is visible. Background elements remain fixed without uniform shifting.
