Remix Video

Use Sora 2 Remix video API (POST /v1/videos//remix) to transform an existing video_id with new prompts, style, and variations via CometAPI.

POST /v1/videos/{video_id}/remix

}

Use this endpoint to create a variation of a completed Sora video without starting from scratch. Remix works best when you keep the change narrow and explicit.

Good remix prompts

• Ask for one clear change instead of rewriting the whole scene
• Keep references to lighting, palette, camera motion, or mood specific
• Start from a completed source video, not an in-progress job

Remix flow

1. Finish the base render first

   Create a source video with Create Video and wait until it completes.

2. Submit the remix request

   Pass the completed video_id with a prompt that describes one focused change.

3. Poll and download the remix

   Treat the remix response as a new async job, poll it with Retrieve Video, then download it with Retrieve Video Content.

How it maps to OpenAI

This follows OpenAI’s documented remix pattern. CometAPI keeps the same concept, but you stay on the CometAPI base URL and auth model for the whole workflow.
