Export formats
Each project kind offers its own set of export formats.
| Format | What it’s for | Notes |
|---|---|---|
| MP3 | Audio-only export, with the audio description narration mixed into the track | |
| MP4 | Full video export, with the audio description narration mixed in | |
| SRT | Subtitle/caption file | Always free, on every plan. |
Projects created from a YouTube link can only be exported as SRT; MP3 and MP4 export are not available for YouTube-sourced projects.
A video project can also be published as a share link or an embedded player rather than exported as a file. That isn’t a format — descriptions are delivered live and each viewer chooses how they receive them, including for YouTube-sourced projects. See Share a video.
