# Export a video to MP4

`POST /exports`

Starts rendering a completed video into a downloadable MP4 file. The rendering runs in the background and typically takes 30 seconds to 5 minutes depending on video length.

**Cost:** Free. All credits were already consumed during video generation.

**Requires:** A prior paid subscription.

**After exporting:**
1. Poll `GET /videos/{id}` and check the `exportStatus` field until it is `completed`.
2. Then call `GET /exports/download?videoId={id}` to get the download URL.
