Troubleshooting video and audio export issues

We always recommend using the Publish feature to export audio and video (and then download the file) instead of the normal export flow. Publish can be up to 10 times faster than exporting audio/video files, and we find it to be more stable than local exports.

The audio or video is out of sync after export
Did you record your files outside of Descript? If so, that can sometimes lead to a/v sync issues in the source file. It may have been encoded with an unsupported encoding, or have issues with corrupted underlying file metadata.

It may be helpful to load the source file in a video player on your computer and see if it's also out of sync. If it is:

    • Try re-exporting the original file with the same settings
    • Try re-exporting the file with a different file extension or encoding
    • Reach out to the third-party hardware or software provider for assistance in troubleshooting
"Export failed" error messages
Sometimes you'll get a message that export failed for some reason. Here's how to interpret those error messages and what you can do about them.

Error: Could not get local path for requested asset

This means you're missing a file, maybe because it hasn't finished downloading. Wait for your project to download and try again, or you can replace the file by following this guide.

Error: Cannot create a word with endTime <= startTime

This error may indicate an issue with the Composition's underlying alignment data. To resolve try clicking the Help menu > DebugForce fix corrupted alignment.

Choppy video playback in the editor or exported file
Choppy playback could be caused by a low composition frame rate setting. To resolve this, increase your composition's frame rate setting in the Aspect ratio and video settings menu.
Error Messages on Web Export (Beta)
Exporting Video, Audio, and GIFs on the Web is now in Beta. You may experience slowness or encounter bugs while this feature is in Beta. Web export works best on a Chromium-based browser, such as Google Chrome, Edge, or Opera. You may encounter issues using Safari. Video export will not work if you are on an unsupported browser such as for Firefox or Internet Explorer.
  • "Export failed" error messages

    • "File format is currently not supported by the web beta": If your project contains ProRes or other file formats that do not play back in the web, you also won't be able to export the project. GIF exports do not work on unsupported browsers.
  • If you run into issues, try exporting with our Desktop app. Alternatively, you can always select the Publish tab and then download your content by clicking the download icon.
