Supported File Types

Descript supports most common audio, video, and image formats. A few things to keep in mind before importing:

Each plan has its own file upload size limit (with a 50 GB max). See our pricing page for details.
Files with three or more audio channels are automatically downmixed to stereo on import. To work with individual channels, split the file into mono tracks first.
HDR video is supported but currently in beta — you may notice some slowness during editing and exporting.
