Video Remix

On the basis of a completed or available Veo video task, submit a new remix task via POST /v1/videos/{video_id}/remix. The API still returns an OpenAI-style video object.
  • The path parameter video_id is the original video task ID.
  • The request body must include both prompt and model.
  • A commonly used example remix model is veo_3_1-extend; the actual available model depends on the current channel.
  • The remixed_from_video_id in the new task response points to the source video ID.
