When you add a file to a project or record directly in Descript, the app saves two file versions:
- A copy of the imported file; or, if you're recording in Descript, a new file. This version will be used when you export or publish your composition.
- An optimized version that is smaller, making them easier to share, improving playback and editing performance, and taking up less space on your hard drive.
Both file versions are stored locally. The files are also uploaded to the cloud, so you never need to worry about misplacing the files referenced in a project.
Optimized files use the following settings:
|Bitrate||Maximum of 256k for mono audio, 320k for stereo audio*|
*if your source audio bitrate is lower than that, the imported file will keep its original bitrate
For users with higher performing computers, creating optimized video files for playback may be unnecessary and potentially cause performance overhead. You can disable Optimize video files for playback from the app preferences or project settings.
How Descript handle files with different sample rates
If your project contains audio files with different sample rates (e.g. 44.1k, 48k), Descript treats them as follows:
- For timeline exports, Descript converts all the files to the highest sample rate in the project.
- All files will be at a 44.1k sample rate during playback in the app.
