name: vehicle-stunt-character-clip
description: Use when making a 9:16 social short where the project character (e.g. Yujeong) appears on a ride such as a tank, helicopter, armored vehicle, boat, jet ski, supercar or motorbike. Also for scenes that mix situations, like military hardware + a party. Runs in this order — first frame that locks the character's face → Seedance 2.5 video → sync to the original song → local fixes for defects in the editor → export and review. Example triggers — Yujeong on a K2 tank, shooting champagne from a helicopter, tank charging video, vehicle stunt video, remove the shell casings, the tank is turning, redo it like v2, character on a tank/helicopter, vehicle stunt short, keep the song timing.

# Vehicle stunt character video

## When to use
- When newly making or fixing a short vertical video where the character poses, dances, toasts or stages a shot on or beside a ride (military, civilian, water or air).
- Replacing the person of an existing source video as is belongs not to this skill but to dance-character-swap or vehicle-character-swap.
- UI names below are given in English; if the app shows them in another language (for example Korean), find the item with the same meaning. Write replies, comments and reports in the user's language.

## Fixed rules (the user's rules take priority if any)
- Use Seedance 2.5 for video and GPT Image 2.5 for images. Do not use Kling.
- Always keep the character's face. Attach the person photo (e.g. Yujeong.png) as a reference every time.
- Never change a status to Approved. Leave results in Needs review.
- Never overwrite the user's edit or a version the user picked. Always make a new version file.
- Do not generate logos, numbers or lettering; add them as editor text.

## Folder structure
Under a folder named after the vehicle, keep these subfolders.
- 01_Input: original song, reference video
- 02_FirstFrame
- 04_AIGenerated
- 05_Final

Keep real reference photos of the vehicle (e.g. K2 1.png, Blackhawk 3.jpg) directly in the vehicle folder.

## Ask the user before starting
The point of this skill is not to remake the example but to make the user's own video. Before starting, ask the questions below together, in one message.
- Skip anything the request already answers.
- If the user says "you decide" or "use the defaults", go with the defaults in parentheses.
- If the user seems to have no idea yet, briefly suggest 2–3 options that differ from the example.
- Once answered, show a one-line summary of what was decided, then start.

1. Which vehicle? Tank, helicopter, boat, supercar and so on. Do you have real reference photos?
2. Which character leads, in what outfit? (default: the project person in the photo's outfit)
3. What happens in the scene? Pose, dance, toast or staged shot, and the ending. With no idea yet, the agent suggests 2–3.
4. Background and time of day? (default: a city road at night)
5. Is there a song? How long? (default: no song, 10 s)
6. Add captions or a logo? (default: none; if yes, as editor text)

## 1. Planning: split the scene into "states" and "movements"
- For 10 seconds, split into 3–4 beats. Example:
  - 0–2 s: character pose
  - 2–5 s: helicopter appears, bottle toss
  - 5–8 s: shot destroys the bottle
  - 8–10 s: tank charging ending
- Decide who handles each beat.
  - AI handles: vehicle driving, camera moves, big motions like shooting
  - The editor handles: captions, logos, exact numbers, local masking
- If there is an original song, set beat times to its rhythm (the drop).

## 2. First frame (GPT Image 2.5)
- Attach as references:
  - 1 person photo
  - 1–2 real photos of the vehicle (to lock its shape, paint and turret)
  - if needed, photos of extra gear (e.g. a minigun door gun)
- Put in the prompt:
  - 9:16 vertical, cinematic live action
  - character position (e.g. standing on the tank turret)
  - vehicle direction (e.g. driving straight toward the camera)
  - background, time of day, lighting
  - "same face as reference"
- Zoom in and capture the face and the vehicle shape to check them. If something is off, remake at the first-frame stage. It will not be fixed at the video stage.

## 3. Video generation (Seedance 2.5)
- Enter configs explicitly every time: `{resolution:"1080p", durationSeconds:10, aspectRatio:"9:16", generateAudio:false}`
  - Sound off; lay the original song in the editor.
- Attach as references: first frame + person photo (+ the "favorite version video" from the regeneration rules below)
- Get the estimate with exactly the arguments you will send. Attaching a reference video raises the estimate (e.g. 593 → 790). Use the estimate as maxCredits.
- Write vehicle movement flatly, and list forbidden movements separately.
  - e.g. "The tank drives straight forward the entire time; no turning, rotating, spinning, drifting or reversing."
- Cautions when adding gunfire:
  - Shell casings, sparks and falling objects easily break into a string of orange rectangles.
  - If not needed, write: "absolutely NO shell casings, no glowing orange rectangles, nothing falling from the door"
  - For destroying a target (a bottle etc.), state only the result briefly, like "shatters into glass and liquid".
- If speed matters, add "fast, same speed throughout, no slow motion".

## 4. Regeneration rules (most important)
- Regenerating produces a whole new video. It is normal for things other than the fix (speed, vehicle rotation, expressions) to change.
- When the user says "vN is the best", handle it in this order.
  1. **Local fix by editing (0 credits, default)**
     - Leave the vN original as is.
     - Overlay the same time of vN on the track above, only over the problem stretch.
     - Crop the overlay clip (px) to leave only the problem area.
     - Apply an effect (blur 50–70, mosaic) or a cover mask.
  2. **If the user explicitly asks to regenerate**, attach the vN video as a motion and speed reference.
     - Prompt: "Recreate the reference video exactly (same shots, camera, speed, timing). ONLY CHANGE: …"
     - Write only one thing to change.
  3. If the same defect appears twice, stop editing the prompt. Change the method (trim → dissolve → editor patch → regenerate, in that order).
- Do not patch by covering with a still-frame image. Sky and background colors shift over time, so a rectangle's edge shows. Cover with the same moment of video.

## 5. Editing and sync
- Lay versions on the edit timeline 12 seconds apart to compare (e.g. 120·132·144 s…). Check the next free slot with get_timeline_layout.
- Put the video on V3 and the original song on A1 with the same start and the same length (frame-accurate, e.g. 10.0333 s).
- Keep local patch layers on the track directly above the original, with length only over the patched stretch.

## 6. Export and review
- export_draft range is the start–end of that stretch (e.g. 182–192.0333).
  - Name: `YJ_<vehicle>_<character>_<scene>_Final_1080p_vN`
  - Folder: 05_Final
- Confirm UPLOADED with get_project_file. Leave the status at Needs review.
- Leave a task comment: model, references, prompt essentials, the one thing changed, original fileId, moments for a person to check.
- Frame checks:
  - Open the editor fresh and wait 30 seconds.
  - Check in the order seek_editor → get_app_screen → canvas capture.
  - Moments to check: start, beat changes, the shooting stretch, ending.
- In this app, inspect_app_media fails to decode the mp4 codec. capture_app_screen locks for that run after 5 consecutive failures, so after 2 failures wait or reopen the editor.
- If you could not capture, write the moments and items you could not check in the report and the comment. Never say you checked them.

## 7. Checklist
- [ ] Does the character's face match the person photo?
- [ ] Does the vehicle's shape match the reference (turret, wheels, number of rotors)?
- [ ] Are the vehicle's direction and speed consistent from start to end (no turning, reversing or slow motion)?
- [ ] Do the shooting and destruction land on the beat, with no breakage such as shell casings or orange rectangles?
- [ ] Do the main actions match the original song's beat?
- [ ] Is everything that must not change from the previous version unchanged?

## 8. Report format
1. Result (file name, folder)
2. How and at which moments it was checked
3. What a person should check
4. Credits (estimate and actual charge kept separate)
