# Video Remix

> Submit a remix based on an existing Grok video task using `POST /v1/videos/{video_id}/remix`.

# Video Remix

OpenAI-format entry point. For unified video, use [Video Remix (Unified Video)](./unified-remix) (`POST /v1/video/remix`, pass `task_id` in the Body).

Based on an existing Grok video task, submit a remix task via `POST /v1/videos/{video_id}/remix` to generate variants with new prompts and aspect ratio parameters.

* The path parameter `video_id` is the original video task ID.
* The request body is JSON and must include `model`, `prompt`, `size`, and `aspect_ratio`.
* After a successful submission, the new task `id` and `status` are returned. Please poll using [Grok Task Query](./query) or [Query Task](./unified-query) for unified video, depending on which pipeline the original task belongs to.
