Director — Frame Gen

Create the identity-locked starting image required by Kling Motion Control.

1. Extract frame zero

Use the raw API so frame zero is sent as the required numeric array. The call is synchronous:

POST https://api.vidjutsu.ai/v1/extract
Authorization: Bearer <VIDJUTSU_API_KEY>
Content-Type: application/json

{"mediaUrl":"<staged source URL>","frames":[0]}

Use frames[0].url as firstFrame. Extract is limited to 100 requests/day.

2. Resolve a reusable character

Prefer an existing tenant-owned character ID. Otherwise create one once:

POST https://api.vidjutsu.ai/v1/characters
Authorization: Bearer <VIDJUTSU_API_KEY>
Content-Type: application/json

{"prompt":"<identity description>","referenceImageUrl":"<optional HTTPS image>"}

Store the synchronous response {id,imageUrl,model} and reuse id.

3. Create the starting image

POST https://api.vidjutsu.ai/v1/clones/starting-image
Authorization: Bearer <VIDJUTSU_API_KEY>
Content-Type: application/json

{
  "firstFrame": "<frames[0].url>",
  "characterId": "<char_...>",
  "prompt": "Replace only the performer identity while preserving pose, framing, lighting, clothing silhouette, background, and composition."
}

This call is synchronous and returns {imageUrl,model}. Vidjutsu sends the two images through the authenticated tenant's scoped Gateway allocation and enforces removal of captions, watermarks, and platform UI.

Rules

• firstFrame, characterId, and prompt are all required.
• Do not send legacy identity-image or source-video fields.
• Do not call an image provider directly.
• Reuse completed extraction, character, and starting-image results.
• These stages share the 50/day clone admission group and have no separate

per-operation charge.
