A man wearing a yellow backpack and brown shorts walks across a field, moving forward while holding a hose; he turns to face the direction he came from before resuming his path. The camera follows him at a slight angle with minor shake.

A single person is walking, carrying a yellow and blue container on their back. The motion is consistent with human locomotion.

The background (field and trees) is stable with no fluid or wind motion; no fire, water, smoke, or strong wind effects are visible.


A right hand holding a light-colored pencil enters from the right, pointing to a Sudoku grid cell and writing in another cell before withdrawing. The camera remains stationary in a top-down view, with a warm light source visible on the left side of the frame.

A hand holding a pencil is moving across the Sudoku grid, pointing to and interacting with individual cells.

No shifting background elements observed; no fire, water, smoke, or wind motion present in the scene.


A person's hands use a white-handled spatula with a blue blade to press a brown crumbly mixture into a metal bowl. The hands move the spatula in circular motions, spreading the mixture evenly across the bowl's base. The person then lifts the bowl to display the smooth, even layer. The camera remains in a top-down perspective, focusing on the hands, bowl, and wooden surface with alternating light and dark strips.

Discrete solid objects: hands (left and right) and a blue spatula moving within the metal bowl. The motion of the spatula and hands is causing the stirring of the brown substance.

The background (wooden table) is static with no shifting. No fire, water, smoke, or wind present. The dominant motion is the hands and spatula stirring the mixture.


A person in a black suit and white shirt adjusts a black bow tie, pulling it up and securing the knot with assistance from another individual's hands. The scene transitions to a top-down view of five bow ties (black, red plaid, green, pink, and maroon) arranged on a surface, with a hot glue gun being used to attach one.

Two people (a man in a suit and an assistant's hands) adjust a tie and jacket; a hand points to bow ties and a box in the second scene.

Background is a static plain wall and white surface throughout. No fluid motion (fire, water, smoke, wind) detected.


A woman in a blue dress walks into the frame from the right, moving toward the center to present in front of a weather graphic display. She gestures with her hands as she speaks, standing with her back slightly angled to the screen. The camera remains static, capturing her position against a distant cityscape backdrop.

The weather reporter is walking across the frame, moving from right to left.

The background (mountains and studio backdrop) is static with no fluid or environmental motion (fire, water, smoke, wind).


A child in a dark shirt and shorts walks across a wooden floor toward a blue mat, then runs toward a windowed area, approaching a wooden bench and yellow box, where they lean against the bench near a window. The camera pans to follow the child’s movement.

A child (solid, distinct object) walks across the mat, approaches a table, and climbs a step ladder. Motion is due to locomotion (walking and climbing) and is easily trackable with a bounding box.

The background elements (blue mat, wooden shelf, wall, window structure) show no shifting or fluid motion. No fire, water, smoke, or wind effects are present.


A hand holding a wooden paintbrush with a metal ferrule and dense bristles enters from the left, moves the brush toward a dark wooden surface with prominent grain, positions it horizontally on the wood, and then withdraws the hand, leaving the brush resting on the surface. The camera maintains a top-down perspective throughout, with a dark background.

A hand is moving a paintbrush across the wooden surface, applying force to the brush for painting.

The wooden background is static and shows no shifting. No fluid or environmental motion (fire, water, wind) is present.


A person's face appears briefly before the camera shifts to close-up shots of hands using a knife to cut the head off a large pineapple with orange-brown skin and green leafy top, positioned on a cutting board. The hands steadily slice through the pineapple's crown, removing the head. The camera maintains a tight focus on the hands and pineapple throughout the action.

Discrete solid objects (hands holding pineapple, knife cutting pineapple) exhibit motion due to explicit physical forces (cutting action).

Background elements (walls, door, cutting board) remain static throughout; no fluid environmental motion (fire, water, smoke, wind) is present.


A person wearing a light blue shirt and a gold chain holds a white earphone cord near their ear, adjusting it slightly while looking forward. The background features an indoor setting with brown walls. The camera maintains a static, close-up perspective throughout.

A person in a blue shirt is visible, with minimal head and hand movements (consistent with talking on a phone).

Background is static (walls) with no shifting or fluid/environmental motion. No fire, water, smoke, or wind observed.


RAW CAPTION: Got it, let's break this down. The video starts with a white screen showing text about earbuds, but the rules say to exclude text recognition. So skip that. Then the next scenes: a woman in a gym, wearing a dark top, boxing. First frame (second 0.3) is white with text (ignore). Then frame 1: close-up of woman in gym, arms raised, wearing pink gloves (wait, no—wait, the second frame is the first video part. Wait, the video sequence: frame 0 is white with text, then frame 1 is the first scene. Wait, the user provided video frames: [0.0] is white with text, [1.4] is a close-up of woman lifting something (maybe a weight?), then [2.5] she's punching, [3.6] continues punching, [4.7] same.

Wait, the actual video: the first part (0.0s) is text (ignore), then starts with a woman in a gym. Let's check the frames:

- [0.0]: white screen with text (ignore per rule g)
- [1.4]: close-up of woman's arm (maybe lifting weights? She's wearing a dark top, pink gloves?)
- [2.5]: more of her arm, now she's punching a heavy bag (or something), her gloves are pink (left hand) and black (right hand, maybe).
- [3.6]: she's punching, hair tied up, black boxing gloves with "NIT" on them.
- [4.7]: same as 3.6, continues punching.

So main subject: a woman, wearing dark top, boxing gloves (pink and black), hair in ponytail. She's in a gym, punching a bag.

Chronic order: starts with a close-up of her arm (maybe lifting weights? Wait, frame 1.4 is "a close-up of a woman's arm lifting something" but maybe she's in a gym. Wait, the second frame (1.4s) shows her with pink gloves, then 2.5s she's punching, so she transitions from lifting (maybe weights) to boxing.

Wait, frame 1.4: close-up of woman's arm (she's holding something, maybe a weight), wearing dark top. Then 2.5s: she's in a boxing stance, pink gloves, punching. 3.6s: continues punching, hair in ponytail, black gloves (with "NIT" visible). 4.7s: same, punching.

So steps:

- Starts with a close-up of the woman's arm (wearing pink gloves, dark top) lifting an object (maybe a weight).
- Then transitions to her boxing, wearing a dark top, pink and black gloves, hair tied back in a ponytail.
- She punches a heavy bag repeatedly, moving her arms and body to hit it.
- Background is a gym with dim lighting, minimal details.

Camera: starts with close-up on her arm, then follows her motion, slightly shifting to capture her upper body and the punching motion. Camera perspective is close-up, then medium shot as she punches.

Mention spatial relations: she's in front of the heavy bag (boxing bag), arms moving towards it.

Now, apply rules:

a) Focus on motion: she lifts (first part) then punches. Wait, the frames: frame 1.4 is arm lifting, then 2.5 is punching. So chronological order: starts with lifting (close-up), then switches to punching.

b) Appearance: woman, dark top, pink gloves (first part), black gloves (punching), hair in ponytail.

c) Spatial: boxing bag in front of her (during punching), gym setting.

d) Camera: starts with close-up on arm, then follows her punching (medium shot, slight movement to follow action).

e) Background minimal: gym, dim lighting.

f) Exclude text.

So caption:

A woman wearing a dark top and pink boxing gloves lifts a weight in a gym, then transitions to punching a heavy bag with black gloves, her hair tied in a ponytail. She continues punching the bag in front of her. The camera starts with a close-up of her arm and then shifts to a medium shot following her movements.

Wait, check rules: "Briefly describe their appearance and number (color, size, orientation)."

Number: one woman.

Appearance: dark top, pink gloves (initially), then black gloves (punching). Hair in ponytail.

Motion: lifts (first action), then punches.

Chronological: first lifting, then punching.

Camera: starts with close-up, then shifts.

Let me structure:

- Initially, a woman in a dark top wears pink gloves and lifts a

A person wearing boxing gloves is punching a heavy punching bag. The person's arm motion and the bag's recoil are due to explicit physical collisions.

The background (gym walls and punching bag) is static with no significant ambient environmental motion (fire, water, smoke, wind).


Two hockey players, one in a black shirt and shorts, the other in a white shirt with red accents and black pants, skate on an ice rink. The player in white moves toward the black-shirted player, who shifts position to the right while both maintain stick control. The camera follows their movement with a slight pan.

Two hockey players (white/black uniforms) and a puck are moving. Players exhibit skating locomotion and stick manipulation; puck shows controlled displacement due to player interaction.

No shifting background elements; no fire, water, smoke, or wind motion detected. Rink boards, spectator banners, and logos remain stationary throughout.


RAW CAPTION: Got it, let's tackle this. First, the video shows a person in a blue shirt and khaki shorts standing on a grassy hill. Then a child, wearing a colorful top and light blue pants, is lying on the grass. The child moves from lying down to crawling. The person in blue is initially near the child, then steps back. The child crawls towards the camera, maybe? Let's check the frames. Frame 0: person standing, child lying. Frame 1: child starts moving. Frame 2: child is on back, then frame 3: crawling on hands and knees. Frame 4: still crawling, frame 5: person steps back. So the sequence is: person stands, child lies, child moves to crawl, person steps back. Need to be chronological. Appearance: person in blue shirt, khaki shorts; child in multicolored top, light blue pants. Spatial: child is on grass, person is near. Background is grass and trees, but keep minimal. Camera: seems stationary, maybe slight shake? Wait, the rules say describe camera perspective and movement. The video's camera might be static, but the frames show the child moving across, so camera is fixed. Let's structure the caption.

Start with the person in blue shirt and khaki shorts standing on a grassy hill. Then the child (colorful top, light blue pants) lies on the grass, then crawls towards the camera. The person steps back as the child moves. Keep it concise. Mention motions in order. Let's draft: "A person in a blue shirt and khaki shorts stands on a grassy hill, then steps back as a child in a colorful top and light blue pants lies on the grass, moves to a crawling position, and advances toward the camera." Wait, check the rules: focus on motion and behavior in chronological order. So first, the person is standing. Then the child is lying, then crawls. The person steps back. Let's sequence: The person in blue shirt and khaki shorts stands on a grassy hill. The child in colorful top and light blue pants lies on the grass, then crawls forward. The person steps back. Background: grass and trees, but minimal. Camera: stationary? The video seems to have a fixed camera, so maybe "fixed camera perspective." Wait, the rules say "conclude with camera perspective and movement." So the camera is static, maybe. Let's see the video frames: the camera doesn't move, just the subjects move. So camera is stationary. Now, let's put it all together. Make sure it's concise. Check the output format: <caption_output>...<caption_output>

So, "A person in a blue shirt and khaki shorts stands on a grassy hill, steps back, and watches as a child in a colorful top and light blue pants lies on the grass, then crawls forward toward the camera. The scene is captured from a stationary camera perspective with minimal background detail." Wait, but need to keep background minimal. The background has trees and grass, but the rules say "keep background descriptions minimal unless essential for understanding motion." Here, the grassy hill and trees are part of the setting, but maybe just mention grassy hill. Let's try: "A person in a blue shirt and khaki shorts stands on a grassy hill, steps back, and observes a child in a colorful top and light blue pants lying on the grass. The child then crawls forward toward the camera, moving from a prone position to a crawling stance. The video is filmed from a stationary camera perspective with a grassy hill and trees in the background."

Wait, but the rules say "briefly describe their appearance and number." So the person: blue shirt, khaki shorts. Child: colorful top, light blue pants. Number: one person, one child. Motion: person stands, steps back; child lies, crawls. Spatial: child on grass, person initially near, then steps back. Camera: stationary.

Let me check each rule:

a) Motion and behavior chronological: person stands, steps back; child lies, crawls forward. Yes.

b) Appearance: person (blue shirt, khaki shorts), child (colorful top, light blue pants). Number: 1 each.

c) Spatial: child on grass, person near child initially, then steps back. Yes.

d) Camera perspective: stationary.

e) Background minimal: grassy hill, trees (but maybe just "grassy hill" as essential for motion).

f) Exclude text, names, stylistic: yes.

g) Don't output reasoning.

So final caption: "A person in a blue shirt and khaki shorts stands on a grassy hill, steps back, and watches as a child in a colorful top and light blue pants lies on the grass, then crawls

A child (solid object) moves via crawling on the grass, while an adult remains mostly stationary. The child's motion is distinct and trackable with a bounding box.

The background features static trees and grass with no uniform shifting or fluid/environmental motion (e.g., wind, smoke). No fire, water, or wind effects dominate the scene.


RAW CAPTION: Got it, let's tackle this. First, I need to understand the video. It's a room with a stage, people sitting at tables, a projector screen. The main subjects are the people on stage and the audience. Let's go chronologically.

The video starts with a group on stage. There's a person in a red vest maybe? Wait, the first frame: a person raising hands, then another person holding a mic. Then a woman in a black vest with red scarf? Wait, no, the rules say focus on motion and behavior. Let's see the sequence.

Looking at the frames: at [0], a man in a cowboy hat (maybe) is raising arms. Then [1] he's still raising, then [2] he's holding a mic, maybe talking. Wait, the movement: the man on stage is raising arms, then the woman in the black vest (she's at the table, speaking into mic). Then the audience is seated. The room has a Christmas tree, American flags. But background minimal unless essential. So focus on actions.

Chronological: The video shows a person on stage raising their arms (first frame), then another person (maybe a woman) speaking into a microphone at a table. The audience is seated, watching. The camera seems to pan left slightly, showing different angles of the stage and audience. Let's check the rules: motion and behavior. So first, man raises arms, then woman speaks into mic. The camera movement: from the initial frame to the next, it's panning left to show the stage and audience. Background: Christmas tree, flags, but minimal.

Now, concise paragraph. Start with main subjects: People on stage and audience. Motion: A person raises arms; a woman in a black vest speaks into a mic. The audience sits at tables. Camera moves slightly, panning left. Let's structure:

The video depicts a scene where a person on stage raises their arms, followed by a woman in a black vest speaking into a microphone at a table; seated audience members observe the proceedings. The camera pans left, shifting focus between the stage and audience. Background elements include a decorated Christmas tree and American flags, but the primary focus remains on the actions of the stage participants and the audience.

Wait, need to be more concise. Let's check the rules: chronological order. So first action: man raises arms, then woman speaks. Camera movement: slight pan left. Let's count the frames: from 0 to 4.5 seconds, the camera moves left, showing more of the stage and audience.

Final caption should be a single paragraph. Let's write:

A person on stage raises their arms while another individual in a black vest speaks into a microphone at a table; seated audience members observe. The camera pans left, capturing the stage and audience from varying angles, with background elements like a Christmas tree and flags visible but secondary to the primary actions.

Wait, check for rules: include appearance briefly. The person on stage: maybe a man (but rules say exclude named characters, but appearance: color, size? "individual in black vest" is okay. The camera movement: "pan left". Let's make sure.

Another pass: At the start, a person raises their arms on stage; a woman in a black vest speaks into a microphone at a table, while audience members sit at tables with red cups. The camera pans left, showing more of the stage and audience over time. Background includes a Christmas tree and American flags but is minimal.

Wait, the rules say "briefly describe appearance and number". So "a person" (number 1) raises arms; "a woman in black vest" (number 1) speaks. Audience is multiple people.

So: A man on stage raises his arms, then a woman in a black vest speaks into a microphone at a table as seated audience members observe. The camera pans left, capturing the scene from a slightly elevated angle with minimal background detail. Background elements include a Christmas tree and flags but are not the focus.

Wait, the user said "exclude text recognition, named characters". So we can't say "man" or "woman" as named, but describe appearance. So "a person in a dark vest" (black vest) speaking into mic. Let's check:

Original frames: the woman is wearing a black vest, maybe a red scarf? But maybe too detailed. Let's keep it simple.

Final attempt:

A person on stage raises their arms, followed by a woman in a black vest speaking into a microphone at a table; seated audience members observe. The camera pans left, shifting focus between the stage and audience. Background elements include a Christmas tree and flags, but the primary focus remains on the stage actions and audience.

Check rules: chronological order (first raising arms, then speaking), appearance (black vest, seated audience), spatial (on stage, at

People in the audience and on stage exhibit discrete movements (e.g., gesturing, shifting positions), indicating physical locomotion or intentional motion.

Static background elements (stage setup, Christmas tree, walls) show no uniform shifting. No fire, water, smoke, or wind-driven motion observed.


A hand with a gold ring moves into the frame from the right, placing fine, light-colored fibers onto a hook held in a vise. The hand adjusts the fibers on the hook, positioning them carefully. The camera maintains a close-up perspective, focusing on the hook and hand throughout.

A hand manipulates a brush to clean a hook, and another hand holds the hook. The motion is controlled and deliberate, driven by physical forces from the hand movements.

The background (text 'fishing whales' and website URL) is static and does not shift. No fluid or environmental motion (fire, water, smoke, wind) is present.


A person wearing a black sports top with purple trim raises their right arm to display a detailed tattoo on the upper arm. They use their left hand to adjust and point at the tattoo, then move their arm slightly to show different angles. The background features a turquoise towel hanging on a rack to the left. The camera remains stationary, capturing a close-up view of the arm and tattoo throughout.

The person's hand and arm are making deliberate, small movements over the tattoo on the upper arm.

Background elements (blue towel and white door) are static; no fluid/environmental motion (fire, water, smoke, wind) observed.


A small boy in white pajamas with blue and red patterns walks while holding a blue bucket, moving toward a white playpen with colorful toys. He bends over to look inside the playpen, then turns back. The camera follows his motion with slight adjustments.

The child (solid object) is moving by walking around the room, bending to pick up a blue bucket, and interacting with the toy structure. The child's motion is discrete and attributable to locomotion.

The yellow wall, toy structure, and furniture remain static with no shifting or environmental motion (e.g., fire, water, wind). Background elements are stable and do not exhibit uniform movement.


A hand wearing a dark sleeve holds a slender golden object, adjusting its position slightly on a textured gray carpet. The camera maintains a close-up perspective with minimal movement, focusing on the hand and object.

A hand holding a tool (scissors-like object) moves repetitively across the carpet surface, indicating intentional physical manipulation of a solid object.

The carpet background is static with no shifting or fluid motion (e.g., fire, water, smoke, wind). Pattern remains consistent throughout frames.


RAW CAPTION: Got it, let's break this down. The video starts with two smartphones showing the Corvo App. One screen has "Finding your dog..." with a circle of dots and a dog icon, the other has options for Kinetic Battery or Bluetooth. Then it cuts to a close-up of a dog's face with a person's hand petting it. Next, a person with a ponytail is seen holding a small, fluffy gray dog in front of a house with greenery. The person is smiling and holding the dog close. Now, I need to describe in chronological order. First, the phone screens, then the petting, then the person with the dog. Main subjects: smartphones, dog, person. Appearances: phones show app, dog is brown (first shot) then gray (later), person has ponytail. Spatial: first phones, then dog close-up, then person holding dog outside a house. Background minimal. Camera perspective: starts with close-up of phones, then close-up of dog, then medium shot of person with dog. Let's structure it: "The video begins with two smartphones displaying the Corvo App interface, one showing 'Finding your dog...' with a circular icon and the other presenting options for 'Kinetic Battery' or 'Bluetooth.' It then transitions to a close-up of a brown dog being petted by a person's hand, followed by a person with a ponytail holding a small gray dog in front of a house with greenery, smiling as they hold the dog close. The camera shifts from static phone views to close-ups of the dog and then to a medium shot of the person with the dog." Wait, check rules: exclude text recognition (like "Finding your dog..."), so don't mention text. Oh, right, rule f says exclude text recognition. So the first part, don't describe the text on the phone, just the app's presence. So revise: "The video opens with two smartphones showing the Corvo App interface; one screen displays a circular icon with a dog, the other shows options for 'Kinetic Battery' or 'Bluetooth.' It then cuts to a close-up of a brown dog being petted by a hand, followed by a person with a ponytail holding a small gray dog in front of a house with greenery, smiling as they hold the dog close." Wait, no, rule f: exclude text recognition. So "Finding your dog..." is text, so don't mention it. So first part: "two smartphones displaying the Corvo App interface; one screen has a circular icon with a dog silhouette, the other shows options for 'Kinetic Battery' or 'Bluetooth'." But rule f says exclude text recognition, so maybe just "two smartphones showing the Corvo App interface" without the text. Wait, the first frame has "CORVO APP" text, but rule f says exclude text recognition, so don't mention that. So the first part: "two smartphones displaying the Corvo App interface, one with a circular dog icon and the other with options for 'Kinetic Battery' or 'Bluetooth'." Wait, no—rule f is "Exclude text recognition, named characters, or stylistic analysis." So "CORVO APP" is text, so don't mention it. So just describe the visual elements without text. So first part: two smartphones showing the app's interface; one screen has a circular icon with a dog, the other shows options (maybe "Kinetic Battery" and "Bluetooth" are text, but since they're options, should we mention? Wait, rule f says exclude text recognition. So maybe just say "two smartphones displaying an app interface, one with a circular dog icon and the other with options for 'Kinetic Battery' or 'Bluetooth'." But is "Kinetic Battery" text? Yes, but rule f says exclude text recognition. So maybe the safest is to not mention the text, just the presence. Wait, the user says "Exclude text recognition"—so if the text is part of the video, don't describe it. So first frame: smartphone on left has "CORVO APP" (text, exclude), a circle with dots and a dog icon (visual), right phone shows "Kinetic Battery or Bluetooth" (text, exclude), but maybe the icons. Hmm. Maybe the instruction is to not include the text content, just the visual. So perhaps "two smartphones: left shows an app with a circular icon and dog silhouette, right shows a map with 'Kinetic Battery' and 'Bluetooth' options" — but no, exclude text. So maybe "two smartphones displaying the Corvo App interface, one with a circular dog icon and the other with options (text excluded)". Wait, the user says "Exclude text recognition", so if there's text, don't mention it. So first part: "two smartphones showing the Corvo App interface, one featuring a

A woman holds a small gray dog, moving the dog upward and adjusting its position. The dog and woman's arms are discrete objects exhibiting controlled motion due to physical interaction (e.g., lifting, holding).

The background elements (blue surface, building facade, greenery) remain static throughout the video. No fire, water, smoke, or wind is present to dominate the motion.


A person in a purple shirt and light pants walks through a forested area, approaches a signpost, touches a tree trunk, then runs away down the path. The camera follows the person from behind, maintaining a steady perspective as they move through the greenery.

A person in a purple shirt moves through the scene via walking, pointing, and touching a tree trunk. Motion is discrete and solid, attributable to human locomotion.

Background elements (trees, foliage, path) show minimal shifting; no dominant fluid/environmental motion (fire, water, smoke, wind) observed.


In a black wok, vibrant red and green bell pepper strips, garlic cloves, and white onion pieces are stirred with a wooden spatula. A hand pours raw pink sausage pieces into the wok, adding them to the vegetables. The camera maintains a top-down close-up perspective throughout.

The card is held with fingers, and the hands display bracelets. In the background, a colorful pink patterned paper and scissors rest on a wooden surface. The camera maintains a top-down perspective throughout.

Discrete solid objects: hands manipulating paper and a small tool. Motion is deliberate hand movements creating folds/shape changes in the paper.

The wooden table and cutting mat show no uniform shifting, indicating no camera motion. No fire, water, smoke, or wind present; environment is static and controlled.


A person's hands use a white cloth to apply light-colored shoe polish to a brown leather shoe, rubbing the cloth over the shoe's surface in circular motions. The shoe rests on a wooden table with a small metal container visible in the background. The camera maintains a top-down perspective throughout the sequence.

A hand moves a cloth back and forth on a leather shoe, applying polish from a container. The hand and cloth exhibit deliberate, discrete motion as they interact with the shoe.

The background (wooden table, metal cup, and shoe tree) remains static with no shifting or environmental fluid motion (e.g., fire, water, smoke, wind).


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

Starting with the first frame: a person is using a sewing machine. The person is wearing a white shirt, and the sewing machine is black. The background has a room with some furniture and fabrics. The main action is the person operating the sewing machine.

In the second frame, the camera zooms in on the sewing machine. The person's hands are visible, guiding fabric. The fabric is blue with a floral pattern. The third frame shows a close-up of the needle stitching the fabric. The fourth frame is a tighter close-up of the needle and thread.

I need to structure this chronologically. So, first the person is using the machine, then the camera zooms in on the hands, then focuses on the needle. The background should be minimal. The person's appearance: white shirt, hands are working. The sewing machine is black. The fabric is blue with floral patterns.

Wait, the rules say to mention spatial relationships if relevant. In the first frame, the person is sitting at a table with the machine. The background has other items, but maybe just mention the room briefly. The camera starts at a medium shot, then zooms in.

The output should be a paragraph. Let me check the example. It's concise, in order. So start with the person using the sewing machine, then camera zooms in on hands guiding fabric, then needle stitching. Mention the colors: person's shirt, fabric color, machine color.

Also, check for any excluded elements: no text, no names. So avoid "sewing machine" being part of the background unless necessary. Wait, the machine is the main subject. The user says "main subjects (people/animals/objects)". Here, the person and the sewing machine are the main subjects.

The camera perspective: starts with a medium shot, then zooms in. The final part should mention the camera movement.

Wait, the user says "conclude with the camera perspective and movement". So the last part of the caption should note how the camera moves. The video shows the camera moving from a medium shot to a close-up, possibly a zoom-in.

Let me put it all together.

First sentence: A person in a white shirt operates a black sewing machine, guiding a turquoise fabric with pink floral patterns through the needle. Then the camera zooms in, showing the needle stitching the fabric, followed by a close-up of the sewing machine's needle in motion. The background includes a room with various fabrics and furniture, but it's minimal. The camera movement is a slow zoom towards the sewing action.

Wait, the user says "briefly describe their appearance and number". So the person is wearing white, the machine is black. The fabric is turquoise with pink flowers.

Also, check the chronological order: the person starts sewing, then camera zooms in on hands, then needle action. So the sequence is: person operating, camera zooms in to show hands guiding fabric, then close-up of needle stitching.

Check if spatial relationships are needed. The person is in front of the sewing machine, hands are guiding the fabric through the machine. Maybe "guiding a piece of turquoise fabric with pink floral patterns through the sewing machine's needle."

In the first frame, the person is seated at a table with the machine. The second frame shows a closer view of the hands. Third frame is the needle stitching, fourth frame is an even closer view of the needle.

So the caption should start with the person sewing, then camera zooms in on hands, then needle. Let me make sure the verbs are in chronological order: operating, guiding, stitching.

Putting it all together concisely:

A person in a white shirt operates a black sewing machine, guiding turquoise fabric with pink floral patterns through the needle. The camera zooms in to show hands positioning the fabric under the needle, then focuses closely on the needle stitching the material. The background remains a softly lit room with scattered fabrics, while the camera maintains a steady close-up on the sewing action.

Wait, the user wants the camera movement to be mentioned in the conclusion. The last part should be "conclude with camera perspective and movement". So maybe end with "The camera slowly zooms in to a close-up of the needle stitching."

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

In the example given, they might say something like "The camera pans left to focus on the sewing machine's needle."

Wait, looking at the provided video frames, the first frame is a medium shot, then the next frames are closer. So the camera moves from a

A person's hands and a sewing machine are interacting with fabric; the sewing machine needle moves to stitch the fabric, indicating discrete physical interaction.

Background elements (walls, furniture) are stationary; no fluid/environmental motion (fire, water, wind, smoke) observed.


A group of shirtless men with varying hair colors and one wearing a white hat stand in a wooded area, gesturing with their hands and passing small objects before shaking hands. The scene then cuts to a top-down view of a grill with cooked food.

Discrete objects (people) are moving hands, shaking hands, and interacting in the foreground, indicating physical locomotion and hand movements.

The background (trees, foliage) remains static with no uniform shifting; smoke from the grill is visible but not dominant motion.


A person with long hair, wearing a dark top and light pants, moves energetically in a dimly lit room. Initially seen from the side, they extend arms outward while dancing, then pivot to face the camera, raising their hands. The camera follows their motion with a slight shake, capturing their dynamic movements against a softly lit background.

A person is moving their arms and body in a dynamic manner (likely dancing or gesturing), with clear solid-object motion distinct from background.

Background elements (couch, wall, room interior) show minimal shifting; no fire, water, or wind-driven environmental motion detected.


Several basketball players, mostly in white shirts and dark shorts with a few in blue, move on an indoor court. A player in a dark shirt shoots the basketball toward the hoop, which enters the net. Subsequently, the group disperses, walking across the court; one player bends down. The camera pans left to follow the action.

Multiple solid objects (people) are moving due to locomotion. Individuals are walking and running across the basketball court, with distinct bounding boxes tracking their motion.

The gym environment (walls, basketball hoops, floor markings) shows no uniform shifting or fluid motion (fire, water, smoke, wind). Static background elements remain consistent across frames, indicating no ambient environmental motion.


A hand moves a small white object across a black and white zebra-patterned fabric on a wooden surface, then picks up a card from the left side of the fabric. The camera maintains a top-down view with no movement.

A hand (discrete object) is moving the zebra-print fabric by pulling and smoothing it. The fabric responds to the hand's explicit physical force (pulling motion), showing direct object-to-object interaction.

No shifting background or fluid/environmental motion observed. The wooden floor remains static, and the zebra-print fabric is a solid object being manipulated. No fire, water, smoke, or wind present.


A person wearing a white jacket over a white tank top and a necklace is seated in front of a circular blue and white structure. They raise their arms upward, then extend them outward, followed by moving their arms in a gesturing motion. The individual leans forward slightly before looking downward. The camera maintains a close-up perspective with minimal movement throughout the sequence.

A man is moving: dancing/gesturing with arms, stepping, and turning. His movements are solid and discrete.

The background is a static geometric pattern with no shifting or fluid motion (no fire, water, smoke, wind).


RAW CAPTION: Got it, let's break this down. The video starts with a grassy area showing a tire, some small metallic objects, a smartphone, and a cable. A person's hand is on the tire. Then the hand moves around the tire, maybe checking it. The camera angle shifts a bit, focusing on the tire and the person's actions. Need to describe the sequence: first the scene with the objects, then the hand movements on the tire. Mention the main subjects (person's hand, tire, objects). Spatial relationships: objects on grass, hand near tire. Camera perspective: starts top-down, maybe slight movement. Let's structure it chronologically.

Start with the initial frame: grass with tire, small objects, phone, cable. Then the hand moves from touching the tire to inspecting it, maybe adjusting the tire's position. The person's hand is on the tire, moving around. The camera angle shifts to show the tire more closely. Need to be concise. Check the rules: no text, no named characters. Keep background minimal (grass is background, but essential for context).

So, the caption should start with the setup: "A person’s hand adjusts a vehicle tire on grass, surrounded by small metallic objects, a smartphone, and a cable. The hand moves across the tire’s hub, inspecting it, while the camera shifts to a closer top-down view, focusing on the tire and the hand’s motion." Wait, need to be concise. Let's check the required elements.

Chronological order: first frame shows grass with tire, objects, etc. Then the hand is on the tire (frame 0-2), then the hand moves the tire slightly? Wait, in frame 2-4, the hand is moving the tire. Let's check the video frames.

[0.0] shows hand on tire, objects on grass. [1.4] similar, hand on tire. [2.5] same. [3.6] hand moving the tire? Wait, the frames: first, hand on tire, then the hand moves to the side, then the tire is being adjusted. The sequence: the person's hand is on the tire, then moves to check the tire's position, maybe tightening or inspecting. The objects (metallic parts) are on the grass. The smartphone is there.

So the caption: A person’s hand inspects a vehicle tire on grass, moving across its hub while a smartphone, small metallic objects, and a cable lie nearby. The camera maintains a top-down perspective, shifting slightly to focus on the tire and hand’s motion.

Wait, need to be precise. Let's check each frame. Frame 0: hand on tire, objects on grass. Frame 1: same. Frame 2: hand on tire. Frame 3: the hand is moving the tire? Wait, the video shows a person's hand on the tire, then moving the tire a bit. Wait, the first frame shows the hand touching the tire, then in subsequent frames, the hand is adjusting the tire's position (maybe loosening it or checking). The objects (the metallic ones) are on the grass. The camera is top-down, focusing on the action.

So the description should be: A person’s hand adjusts a vehicle tire on grass, surrounded by small metallic objects, a smartphone, and a cable. The hand moves across the tire’s hub, inspecting it, as the camera shifts to a closer top-down view.

Check the rules: concise, chronological. Mention motion: hand adjusts tire, moves across hub. Objects: small metallic, smartphone, cable on grass. Camera: top-down, shifts slightly.

Final check: no text recognition, no named characters. Yes. So the caption would be:

"A person’s hand adjusts a vehicle tire on grass, surrounded by small metallic objects, a smartphone, and a cable. The hand moves across the tire’s hub, inspecting it, while the camera maintains a top-down perspective, shifting slightly to focus on the tire and hand’s motion."

Wait, but the output must be concise. Let's make it shorter. "A person’s hand inspects a vehicle tire on grass, moving across its hub while small metallic objects, a smartphone, and a cable lie nearby. The camera shifts to a closer top-down view, focusing on the tire and hand’s motion."

Yes, that's concise. Let's confirm. Chronological: first, the scene with objects and hand on tire, then the hand moves the tire. So the sequence is: hand interacts with tire, objects are there. Camera angle.

Another angle: "A person’s hand adjusts a vehicle tire on grass, surrounded by small metallic parts, a smartphone, and a cable. The hand moves across the tire’s hub, inspecting it, as the camera shifts to a top-down view focusing

A person's hands interact with a car wheel and tools (e.g., unscrewing lug nuts, adjusting the wheel), with the wheel and tools moving due to physical manipulation.

Background consists of static grass and stationary objects (car wheel, tools), with no fluid/environmental motion (fire, water, smoke, wind) or significant background shifts.


Two people sit side by side facing the camera; the person on the left with long blonde hair blows a large gum bubble, then pops it and eats a red item, while the person on the right with long dark hair observes and smiles. The camera remains static with a plain blue background and a computer monitor visible to the left.

Two individuals: left subject blows/pops bubblegum bubble and consumes lollipop (hand/face motion), right subject exhibits facial expressions (smiling/laughing) with no significant body movement.

Background elements (columns, building facade, stairs) show no uniform shifting; water fountain on the right is a minor static environmental feature with no dominant fluid motion.


RAW CAPTION: Got it, let's break down the video. First, there are two people. One is in a blue jacket, the other in dark clothing. They're near a sheep that's been shorn, with a pile of wool. The person in dark clothing is bending over a white bucket, maybe handling something. The sheep is on the ground with its wool removed. Then, the person in blue moves a bit. The background has a grassy field, fence, trees. The camera seems to pan slightly, showing the scene from a slightly shifting angle. Need to note the sequence: the dark-clad person is working with the bucket, the blue-jacketed person is nearby. The sheep is lying there with the wool pile. Let's structure it chronologically.

Start: Two people near a shorn sheep with wool pile. One (dark clothing) bends over white bucket. The other (blue jacket) stands nearby. Then, the dark-clad person is handling something in the bucket, possibly pouring or collecting. The blue-jacketed person moves slightly. The sheep is on the ground, wool pile is large. Background is grassy field with fence. Camera moves a bit, maybe slight pan.

Now, check the rules. Focus on motion: dark-clad person bends, interacts with bucket; blue person is nearby. Spatial: blue person to the left of dark person, sheep on ground. Conclude camera movement: slight pan left or similar. Background minimal.

Let me draft:

A person in dark clothing bends over a white bucket near a shorn sheep with a large pile of wool on the ground, while another person in a blue jacket stands beside them. The dark-clad individual reaches into the bucket, possibly handling an object, as the blue-jacketed person shifts position slightly. The sheep lies on the earth, surrounded by grassy fields and a fence in the background. The camera pans slightly to the right, maintaining a medium shot of the scene.

Wait, check if the direction of pan is correct. From the frames, the camera might be moving. Let's see the frames: frame 0 to 5, the camera shifts. Maybe it's a slight pan left. Or maybe the action is the subjects moving, but the camera is steady? Wait, the problem says to describe camera perspective and movement. Let's see the output example.

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

In the video, the camera might be static but slightly panning. Let's look at the frames: from frame 0 to 5, the camera's angle changes a bit. Maybe it's a slight pan. So, "The camera maintains a medium shot with a slight pan to the right."

Now, check the main points:

- Two people: one dark jacket, one blue.
- Dark person bends over white bucket, handles something.
- Blue person stands, then moves a bit.
- Sheep on ground, wool pile.
- Background: grass, fence, trees (but minimal).
- Camera: slight pan (direction? Let's see the video flow. The first frame, then the camera shifts, so maybe pan left or right. Let's see the positions. The blue person is on the left in the first frame. Maybe the camera moves to show more of the right side, so pan right? But the problem says to describe accurately.

Alternatively, maybe the camera is moving slightly, so "slight pan left" or right. Let's proceed.

Putting it all together concisely:

A person in dark clothing bends over a white bucket beside a shorn sheep with a large wool pile on the ground, while another person in a blue jacket stands nearby. The dark-clad individual interacts with the bucket, occasionally adjusting their position, as the blue-jacketed person shifts slightly. The sheep lies motionless, surrounded by a grassy field and fence. The camera maintains a medium shot with a slight pan to the right.

Check for conciseness, chronological order. The actions: dark person bends, handles bucket; blue person stands and moves. Then the sheep is there. Camera movement.

Another check: "main subjects (people/animals/objects) in chronological order." So first, dark person bends over bucket (action 1), blue person is there (action 2), then maybe the dark person continues the action.

Yes. Let's make sure to mention appearance: dark jacket, blue jacket, sheep (shorn, wool pile), bucket (white), etc.

Final draft:

A person in dark clothing bends over a white bucket next to a shorn sheep with a large pile of wool on the ground, while another person in a blue jacket stands beside them. The dark-clad individual repeatedly reaches into the bucket, possibly collecting or pouring something, and shifts position slightly, as the blue-jacketed

A person in a blue jacket and a black dog are the primary discrete objects showing motion; the person shifts position slightly while interacting with the sheep, and the dog moves within the frame.

The grassy field, fence, and trees in the background show no significant shifting or environmental fluid motion (e.g., wind, water). No fire, smoke, or flowing elements are present.


RAW CAPTION: Got it, let's break this down. First, the video starts with a wide shot of a stage at night, maybe a concert. There's a performer on stage with lights. Then the camera zooms in on the performer. The performer is wearing a black jacket, white shirt, black pants, and shoes. He's moving—walking towards the center, then standing. The lights are yellow/orange. Background is dark with some audience in the foreground. Need to capture the chronological order: start with the stage setup, then zoom to the performer, describe his actions (walking, stopping), appearance. Keep it concise.

Check rules: focus on motion, appearance, spatial relationships. Background minimal. Camera perspective: starts wide, then zooms in. Conclude with camera movement.

So the sequence: [0.0] wide shot of stage with lights and performer; [1.4] zoom to performer walking towards center; [2.5] continues walking, then stops at center; [3.6-4.7] stands still. Performer's appearance: black jacket, white shirt, black pants, shoes. Camera moves from wide to close, so maybe "camera zooms in on the performer" as the movement.

Let's structure the caption:

The video opens with a wide shot of a stage illuminated by colorful spotlights at night, featuring a single performer. The camera then zooms in on the performer, who is dressed in a black jacket, white shirt, black pants, and shoes. The performer walks toward the center of the stage, then stops. The background remains dark with faint audience silhouettes visible in the lower frame. The camera maintains a steady zoom as the performer moves and stands still.

Wait, need to be more concise. Chronological order:

First scene: stage with lights, performer. Then camera zooms in. Performer walks, stops. Describe appearance and motion.

Let me check the frames. Frame 0: stage with lights, performer. Frame 1-4: zoom in, performer walking. Frame 5-6: standing.

So:

A single performer in a black jacket, white shirt, black pants, and shoes walks toward the center of a stage illuminated by yellow and orange spotlights. The camera zooms in on the performer as they move from the left to the center, then stop. The background is dark, with faint audience figures visible in the lower foreground. The camera remains steady, focusing on the performer's movement and stance.

Wait, need to make sure it's concise. Also, the first frame is a wide shot, then the camera zooms in. So start with the wide shot, then zoom to the performer.

"Beginning with a wide shot of a stage at night under colorful spotlights, the camera zooms in on a single performer dressed in a black jacket, white shirt, black pants, and shoes. The performer walks toward the center of the stage, then pauses. The background features a dark audience silhouette in the lower frame. The camera maintains a steady zoom, focusing on the performer's movement."

Check rule g: don't output reasoning. Let's check the rules again.

a) Motion and behavior chronological: stage wide shot, then zoom, performer walks, stops.

b) Appearance: black jacket, white shirt, black pants, shoes.

c) Spatial: moving toward center, audience in lower frame.

d) Camera: zooms in, steady.

e) Background minimal: dark, audience silhouette.

f) Exclude text, names, etc.

So putting it all together:

The video opens with a wide shot of a stage illuminated by colorful spotlights, showing a single performer. The camera zooms in as the performer, dressed in a black jacket, white shirt, black pants, and shoes, walks toward the center of the stage and then stops. The background is dark with faint audience silhouettes in the lower foreground. The camera remains steady during the zoom and movement.

Wait, check length. Need to be concise. Maybe:

A performer in a black jacket, white shirt, black pants, and shoes walks toward the stage center under yellow and orange spotlights. The camera zooms in from a wide stage shot, focusing on the performer's movement as they stop. Background shows dark surroundings with faint audience figures.

Hmm, but the first frame is a wide shot. Let's make sure to mention the initial shot.

"Beginning with a wide stage shot under colorful spotlights, the camera zooms in on a performer wearing a black jacket, white shirt, black pants, and shoes. The performer walks toward the center and then stops, with the dark background and faint audience silhouettes visible in the lower frame. The camera maintains a steady zoom throughout."

That seems better. Let's see if it's concise. Maybe:

The video starts with a wide shot of a stage with bright spotlights, then zooms in on a performer in

RAW CAPTION: Got it, let's tackle this. First, the video starts with a child on a bike in a circular plaza with a sunburst design. The child is wearing a helmet, maybe pink. Then another child on a bike comes in, maybe black helmet. The first child rides forward, then the second one enters. Wait, the sequence: at [0.0], child on bike (maybe pink) in center. Then [0.3], same, then [1.4] a second child on bike appears. Wait, no, looking at the timestamps: first frame shows child on bike, then next frames show more movement. Let's list the events.

Frame 0: Child on bike (small, pink, helmet?) in center of plaza. Plaza has sunburst design, people in background.

Frame 1: Same child, maybe moving.

Frame 2: Another child on bike (maybe black, helmet) enters from left, moves towards center.

Frame 3: The first child is still there, second child moves across.

Wait, the main subjects are two kids on bikes. First kid (maybe pink top, helmet) rides around. Then second kid (black, helmet) enters from left. Let's check the movements: in frame 0, one kid. Frame 1, still. Frame 2, another kid comes in from left (since the frame shows a person in white shirt on the left, but that's a bystander). Then frame 3, the first kid is on the right, second kid is on the left? Wait, the video has a kid in pink, then another in dark clothing.

Wait, step by step:

- [0.0] A child in pink, helmet, rides a bike on a circular sunburst plaza.

- [0.3] Another child in dark clothing, helmet, enters from the left, riding a bike.

- [1.4] The first child continues moving, the second child is now in the frame, both kids on bikes.

- [2.5] A person in white shirt (bystander) walks into frame from left, then exits.

- [3.6] The child in pink is still riding, and the second child in dark clothing rides past.

Wait, the key is to focus on the main subjects (the two kids on bikes). Let's describe their motion chronologically.

At the start, a child on a bicycle (wearing a pink top and helmet) is positioned near the center of a circular plaza with a sunburst design. Then, another child on a bicycle (wearing dark clothing and a helmet) enters the scene from the left side, riding towards the center. Both children continue moving around the plaza; the first child remains near the center, while the second child circles past them. Throughout the sequence, the camera remains relatively stable with slight movements as it captures the children's motion, with a few pedestrians and vehicles visible in the background but not the focus.

Wait, need to be concise. Let's check rules:

a) Motion and behavior in chronological order.

b) Appearance and number: two kids, one pink, one dark.

c) Spatial relationships: first kid in center, second enters from left.

d) Conclude with camera perspective: stable, slight movement.

e) Background minimal: people, cars in background but not essential.

f) Exclude text, names.

So:

A child in a pink top and helmet rides a bicycle in the center of a circular plaza with a sunburst design. Shortly after, a second child in dark clothing and a helmet enters the scene from the left, cycling toward the center. Both children move around the plaza; the first remains near the center while the second circles past. The camera maintains a stable perspective with minor movements, capturing the children's motion against a backdrop of pedestrians and parked vehicles.

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

- First child is there (pink).

- Second child enters from left.

- Both move around.

Yes.

Now, ensure all rules:

a) Motion chronologically: yes.

b) Appearance: pink top, dark clothing; two kids.

c) Spatial: second enters from left.

d) Camera: stable, minor movements.

e) Background: minimal (pedestrians, cars mentioned as "backdrop" but not essential, so okay).

f) No text, names.

Yes.

Now, phrase it concisely. Maybe:

A child in a pink top and helmet rides a bicycle in the center of a sunburst-designed plaza. Shortly afterward, another child in dark clothing and a helmet enters from the left, cycling toward the center. Both children move around the plaza; the first remains near the center while the second circles past. The camera remains stable with slight movement as it captures their motion.

Wait, "sunburst-designed plaza" – yes, the plaza has a sunburst pattern

Multiple discrete objects (pedestrians, cyclists) exhibit locomotion via physical forces (biking, walking). The cyclist in white (frame 1.8-3.5) and children on bicycles (frame 0.0-4.5) move with clear bounding box tracking.

Static plaza tiles and distant structures remain consistent across frames; no fluid motion (fire, water, smoke) or significant wind effects are present.


Two women assist a central woman in a purple sari with gold embroidery. An older woman with white hair in a white outfit adjusts the sari’s right side, while another woman in a red sleeveless top and white headscarf adjusts the left. The central woman stands still, allowing them to fasten the sari. The camera maintains a close-up, slightly panning as the assistants move, with minimal background details visible.

Two assisting women (one in white, one in red) are adjusting the saree of a central woman. Their hands and upper bodies move to adjust the fabric, showing discrete motion.

Background is static (wooden cabinets and decorative items). No fluid/environmental motion (fire, water, wind) present.


A man wearing a black vest and gloves carves a large, transparent ice sculpture with intricate details. He begins standing, bends forward to work on the sculpture, then adjusts his stance while continuing to shape the ice. The camera maintains a fixed perspective, capturing his actions in front of the sculpture.

A person in dark clothing interacts with a large ice sculpture (solid object), performing hand movements to adjust or construct it. The person's motion is deliberate and localized to the sculpture area.

Static dark panels and blue structural elements remain consistent across frames; no visible fluid motion (fire, water, smoke) or wind-driven motion detected.


A person wearing a white t-shirt and white shorts sits cross-legged on a green surface, holding a cup to their mouth. They drink from the cup, then lower it. A large black megaphone is positioned prominently in the foreground, partially obscuring the view. The camera remains static and close-up, focusing on the person with the megaphone dominating the frame.

The person (a solid object) is moving by voluntary hand and body movements, including placing down an object and resting hands.

Background (curtain and furniture) is static and does not shift. No environmental fluids (fire, water, smoke, wind) are present.


A metal ladder with stacked white bags sits against a gray wall. A hand enters from the right, holding a white bag, and places it onto the stack of bags on the ladder. The camera remains static throughout.

A person's hand/arm (discrete object) repeatedly moves and repositions stacked boxes on the ladder, exhibiting controlled locomotion due to physical interaction.

Static background (ladder, wall) with no fluid/environmental motion (fire, water, smoke, wind); no uniform background shift indicating camera movement.


RAW CAPTION: Okay, let's tackle this captioning task. The user provided a video snippet with multiple frames, and I need to create a concise chronological paragraph based on the rules given.

First, I'll go through each frame. The first frame shows a metallic component with bolts. Then a hand appears, using a tool on the bolts. The text "ANY SIZE" is there, but according to rule f, I should exclude text recognition, so I'll ignore that. Next, the scene shifts to a green object with "STRIPPED BOLTS!" text, but again, skip the text. The main subjects here are the hand and the bolts.

Rule a says to focus on motion and behavior in chronological order. So, the sequence is: the hand interacts with the bolts on the metallic part, then moves to another object with stripped bolts. Need to describe the actions step by step. The hand is using a tool (maybe a wrench) to turn the bolts. The metallic part has multiple bolts, probably arranged in a row. The second scene shows a green component with a stripped bolt, where the tool is working on it.

Check for appearance: metallic component with bolts (color silver, maybe), green object. The hand is performing actions. Spatial relationships: the hand is on top of the metallic part, then moving to the green object. Background is minimal, maybe a workbench.

Rule d: camera perspective. The first part is top-down, then maybe a close-up on the green object. The camera might shift between the two scenes.

Need to structure the caption as chronological. Start with the metallic part, hand turning bolts, then the green object with stripped bolts. Mention the hand's actions, the tools, the objects' appearance (silver, green), and the camera perspective.

Avoid mentioning the text. Exclude any named characters or stylistic analysis. Keep it brief.

Let me draft:

A hand uses a wrench on a metallic component with multiple silver bolts arranged in a row, turning them. The scene transitions to a close-up of a green mechanical part where the hand continues working on a stripped bolt with the wrench. The camera remains top-down during the initial action, then shifts to a close-up of the green component.

Wait, check the rules. Rule d says "Conclude with the camera perspective and movement (e.g., top-down, pan left, slight shake)." So the last part should state the camera perspective. The first scene is top-down, then shifts to a close-up. Maybe "The camera starts with a top-down view, then moves to a close-up of the green component."

Wait, in the original video description, the first part is a top-down view of the metallic part with bolts, then a hand interacts. Then the scene changes to a different object with "STRIPPED BOLTS!" but we don't mention text. So the camera moves from top-down to a close-up on the green part.

Let me check the frame order. Frame 0: top-down of metallic part. Frame 1: hand starts moving. Frame 2: hand using tool. Frame 3: shifts to green part with tool working on a stripped bolt.

So the caption should be:

A hand manipulates a wrench on a silver metallic component with multiple bolts arranged in a row, turning them. The scene transitions to a close-up of a green mechanical part where the same hand uses the wrench on a stripped bolt. The camera maintains a top-down perspective initially, then shifts to a close-up of the green component.

Wait, but the user's example might have different wording. Let me check the rules again. Rule c: mention spatial relationships if relevant. The hand is on the metallic part, then moves to the green part. But maybe the spatial relation is not necessary here unless it's essential.

The key points: chronological order of actions, appearance (silver bolts, green component), camera perspective.

Let me try:

A hand uses a wrench to turn silver bolts on a metallic component with multiple bolt holes. The scene shifts to a close-up of a green mechanical part, where the hand continues to work on a stripped bolt with the wrench. The camera starts with a top-down view and transitions to a close-up of the green component.

Check if "stripped bolts" is mentioned. Wait, the text "STRIPPED BOLTS!" is present, but rule f says exclude text recognition. So the caption should not mention "stripped bolts" as text, but maybe describe the bolt being stripped. However, the problem is the video shows the bolt as stripped, so perhaps "stripped bolt" is part of the description. Wait, the user said to exclude text recognition. So if the video shows a stripped bolt visually, we can mention it. But according to rule f, exclude named characters or text recognition. Wait, rule f says "Exclude text recognition, named characters, or stylistic analysis." So if

Hands are actively manipulating a metal plate with bolts, demonstrating physical interactions (grasping, twisting) with discrete objects (bolts, metal plate, tools).

Background elements (workbench, tools) show no uniform shifting; no fire, water, or smoke present, so no ambient environmental motion detected.


RAW CAPTION: Okay, let's tackle this video captioning task. First, I need to understand the user's requirements. They want a concise, chronological paragraph that describes the video, focusing on the main subject's actions, appearance, spatial relationships, camera perspective, and excluding text or named characters.

The video shows a woman in a red blazer holding a CST microphone. The background has a CST logo repeated. The key points are her standing in front of the backdrop, speaking into the mic. Since the video is short (0 to 5 seconds), the main action is her speaking. I need to mention her appearance: red blazer, holding the mic. The background is the CST logos, but the rules say to keep background descriptions minimal unless essential. Here, the logos are part of the backdrop, so maybe just note she's in front of the branded background.

No text recognition, so ignore the name "Tami Arender". The camera is static, as there's no movement mentioned. The caption should be chronological, so start with her standing, speaking into the mic. Check the rules again: don't mention text, names, stylistic analysis. So avoid anything like "CST logo" or her name. Focus on her actions.

Wait, the background has CST logos, but since the user said minimal background, maybe just say "blue backdrop with repeated logos". But the rule says "exclude text recognition", but the logos are part of the background. Hmm, but the logos are part of the setting. The user says "keep background descriptions minimal unless essential". Since the logos are part of the backdrop, maybe it's okay to mention "blue backdrop with repeated 'CST' logos" but not the text. Wait, the user's rule says "exclude text recognition", so maybe the logos are considered text, but the user might consider them part of the background. The example in the problem statement has the text on the screen, but the rules say to exclude named characters and text recognition. So maybe the "CST" logos on the backdrop are part of the visual elements but not text to exclude. Wait, the user says "Exclude text recognition, named characters, or stylistic analysis." So "CST" is text, so maybe avoid mentioning it. But in the video description, the backdrop has "CST" logos, so perhaps it's part of the background. But the user says to keep background minimal unless essential. The main subject is the woman, so maybe the background can be just "blue backdrop" without the logos. Wait, the first frame has the text on the screen, but the user says exclude text recognition. The lower third has "CST" and her name, but the rules say exclude named characters and text. So the caption should not mention "CST" in the text, but the logos on the backdrop might be part of the visual. Hmm, tricky. Let me check the example again.

In the provided example, the video shows a woman in a red blazer with a CST logo, but the caption should not include the name or the text. The user's rules say to exclude text recognition, so the "CST" logos on the backdrop would be considered text, so maybe the caption should just say "blue backdrop" without specifying the logos. Alternatively, maybe the logos are part of the visual context but not text to exclude. Wait, the user says "Exclude text recognition", so if the logos are part of the text (like the word "CST"), then they should be excluded. So perhaps the background should just be described as "blue backdrop with repeated logos" but without naming the logos. But the user says "keep background descriptions minimal unless essential". Maybe the fact that it's a branded backdrop is essential, but the user's example might not mention it. Wait, the user's example output in the problem statement is missing, but according to the problem, the assistant has to generate the caption.

Wait, the rules say: "Exclude text recognition, named characters, or stylistic analysis." So the name "Tami Arender" is excluded. The "CST" logos on the backdrop might be considered text, so perhaps the background is just "blue backdrop" without mentioning the logos. But the video clearly has the CST logos, so perhaps the assistant has to mention the background as blue with logos, but since the user says to exclude text recognition, maybe the assistant should refer to it as "blue backdrop with repeated logos" but without the text. Alternatively, perhaps the assistant is supposed to mention the background elements but not the specific text. Hmm. Let's look at the problem again.

The user's instructions: "Keep background descriptions minimal unless essential for understanding motion." So if the background is essential, like it's part of the scene. But the motion here is the woman speaking. The background might not be essential for motion, but the user might require minimal description

A person in a red blazer is speaking, showing subtle facial movements (lip motion, slight head shifts).

Background features static CST logos with no shifting or environmental elements (fire, water, smoke, wind).


A hand with yellow nail polish gently massages a person's dark hair, moving across the scalp in a slow, circular motion. The hand then lifts away, revealing the person's face as they turn slightly toward the camera. The scene occurs in a kitchen with a white microwave visible in the background. The camera maintains a close-up perspective with minimal movement, focusing on the hand and head interaction.

A hand is moving across a person's head, demonstrating explicit physical interaction (touching, stroking) with a solid object.

Static background elements (microwave, kitchen items) show no uniform shifting; no fire, water, or smoke present.


A baseball batter in a red shirt, gray pants, and red shoes stands at home plate, adjusting his stance before swinging the bat; a catcher in red and white gear crouches behind him, while an umpire in dark clothing stands behind the catcher. The camera remains stationary, capturing the action from a ground-level perspective with minimal background detail.

The batter is moving, swinging the bat. The catcher and umpire show minimal movement.

The background (dugout, trees) is stable with no shifting or fluid motion. No fire, water, smoke, or wind effects are visible.


A person wearing a white shirt and teal tie adjusts their collar with both hands, then manipulates the tie to secure it. The camera maintains a close-up perspective on the upper torso throughout the sequence.

Person's hands and upper body moving to adjust a green tie; solid, distinct objects (hands, tie) undergoing explicit physical manipulation.

Background appears static (indoor wall), no fluid/environmental motion (fire, water, smoke, wind) observed.


RAW CAPTION: Got it, let's tackle this. First, the video shows a person playing a marimba. The main subject is a person in a blue sleeveless shirt and dark pants. They're moving their hands with mallets over the marimba keys. The marimba is black, with bars, and the person is standing to the left of it, maybe? Wait, the video starts with the person partially visible, then comes into view. They're striking the keys with mallets. The background is a white wall and some shelves. Camera perspective: it's a steady shot, maybe slightly shaky. Need to be chronological: the person moves into the frame, uses mallets on the marimba. Let's check the rules. Focus on motion, chronological. Describe appearance: blue shirt, dark pants. Spatial: person is in front of the marimba. Background minimal. Camera: probably static but with slight shake. Let's structure it. Start with the person entering the frame, playing the marimba with mallets. Then the motion of their hands. Conclude with camera. Let's draft: "A person wearing a blue sleeveless shirt and dark pants stands in front of a black marimba, striking its keys with mallets in a rhythmic motion. The individual’s hands move swiftly across the instrument, positioned to the left of the marimba’s center. The camera remains stationary with slight movement, capturing the person’s upper body and the marimba against a plain white wall background." Wait, check if that follows rules. Chronological: starts with person moving into view (frame 0-5), then playing. Appearance: blue shirt, dark pants. Spatial: in front of marimba, to the left of center. Background minimal. Camera: stationary with slight movement. Let's make it concise. Maybe: "A person in a blue sleeveless shirt and dark pants plays a black marimba, using mallets to strike its keys in a fluid motion. The individual moves their hands across the instrument from left to right, positioned slightly left of the frame's center. The camera maintains a steady perspective with minor shake, capturing the action against a plain white wall background." Wait, the video is short, so focus on the key actions. Let's check the original video frames: the first frame has the person's arm moving, then they come into view. So chronological: the person enters the frame (frame 0), then is seen playing (frames 1-5). So caption should start with that. Let's adjust: "A person wearing a blue sleeveless shirt and dark pants enters the frame and begins playing a black marimba with mallets, their hands moving rhythmically across the instrument. The individual is positioned to the left of the marimba’s center, striking the keys in a repeating pattern. The camera remains stationary with slight movement, focusing on the upper body and the marimba against a plain white wall." Check rules: chronological (enters, plays), appearance (blue shirt, dark pants), spatial (left of center), background minimal. Camera: stationary with slight shake. Yes, that works. Let's make sure it's concise. Maybe: "A person in a blue sleeveless shirt and dark pants plays a black marimba with mallets, moving their hands rhythmically across the keys. The individual is positioned to the left of the instrument's center, striking the bars in sequence. The camera maintains a static perspective with minor shake, capturing the action against a plain white wall background." Hmm, "static perspective with minor shake" – the rules say "conclude with the camera perspective and movement (e.g., top-down, pan left, slight shake)". So "slight shake" is okay. Let's confirm: "A person in a blue sleeveless shirt and dark pants plays a black marimba with mallets, moving their hands rhythmically across the keys. The individual is positioned to the left of the instrument's center, striking the bars in sequence. The camera remains stationary with slight shake, capturing the action against a plain white wall." That's good. Let's check if it's concise. Maybe shorten: "A person wearing a blue sleeveless shirt and dark pants plays a black marimba with mallets, moving their hands rhythmically across the keys. Positioned to the left of the instrument's center, the individual strikes the bars in sequence. The camera remains stationary with slight shake against a plain white wall background." Yes. Now check all rules: a) motion chronological (plays, hands move), b) appearance (blue shirt, dark pants), c) spatial (left of center), d) camera (stationary with slight shake), e) background minimal (plain white wall), f) exclude text etc. Looks good.
