If you recorded your files outside of Descript, the source file may have unsupported encoding or corrupted metadata, which can cause sync issues.

Try opening the original file in a video player to see if it's also out of sync. If it is:

• Try re-exporting the original file using the same settings.
• Try re-exporting with a different file extension or encoding.
• Contact the third-party hardware or software provider for help troubleshooting the issue.

If your export fails, here's how to interpret the error message and what to do about it.

Error: Could not get local path for requested asset

This means a file is missing—possibly because it hasn't finished downloading. Wait for the download to complete and try again, or replace the file using this guide.

Error: Cannot create a word with endTime ≤ startTime

This typically points to corrupted alignment data. To fix this, go to the Help menu > Debug > Force fix corrupted alignment.

This may be caused by a low frame rate setting in your composition. Try increasing the frame rate from the Aspect ratio and video settings menu.

Descript for Web supports local exports of video, audio, and GIFs. It works best in Chromium-based browsers like Chrome, Edge, or Opera. You may see errors when using Safari, Firefox, or Internet Explorer.

• “File format is currently not supported on web.”
  Your project may include ProRes or other unsupported formats. These can't be exported from the browser. Exporting as a GIF also doesn't work on unsupported browsers.
• “Export failed due to system memory issues.”
  Close other programs or restart your computer to free up memory. You can also try exporting using the Descript (web link) destination.
• “Export failed due to file system limits in your browser.”
  The file may be too large for your browser to handle. Try the Descript (web link) destination instead.
• “Export failed due to a network connectivity issue.”
  Check your internet connection and try again.

If you're having issues, try exporting from the desktop app. Or export to the Descript (web link) destination and then download your file.

The QuotaExceeded error means your browser has run out of system resources like storage or memory. It’s most often related to localStorage limits on low disk space or large caches.

Quick fixes

1. Free up at least 20 GB of local disk space.
2. Close other tabs and windows to free up memory.
3. Bookmark the Descript web editor to enable persistent storage. Learn more.
4. Clear your browser cache and refresh the page.
   Don't do this if you have files pending recovery.

Other things to try

• Update your browser to the latest version.
• Switch from Incognito/Private mode to a normal browsing window, or use a different browser.
• Reset site permissions for descript.com and restart the browser.
• Review general performance tips.
• Check antivirus or firewall settings that might block Descript.
• Disable settings that auto-delete site data on close. For example: "Delete data sites have saved to your device when you close all windows".

Browser-specific pointers

• Chrome / Edge
  • Go to Settings > Privacy and security > Site settings > View permissions and data stored across sites.
  • Search for descript.com, then either Clear data or confirm it’s not being cleared on close.
  • Under Cookies and other site data, ensure site data isn’t cleared on close for descript.com.
• Safari
  • Go to Settings > Privacy > Manage Website Data.
  • Find and remove descript.com, then reload the page.
  • If you’re using Private Browsing, switch to a standard window.

If your browser continues to restrict storage, switch to the Descript desktop app.
