We recommend using the [Descript (web link)](/export-and-share/export-and-publishing-overview) export destination to export audio and video (and then download the file) instead of using a Local export option and flow. Descript (web link) can be up to 10 times faster than exporting audio/video files, and we find it more stable than local exports. 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](/add-and-manage-media/ts-missing-files). #### 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](/working-in-projects/aspect-ratio) menu. [Descript for Web](/getting-started/descript-for-web) supports [local exports](/export-and-share/video-gif) 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](/add-and-manage-media/supported-file-types). These can't be exported from the browser. Exporting as a GIF also doesn't work on unsupported browsers. * **“Your script is using all the available memory for processing.”**\ Try our publishing feature instead. You can also try exporting using the [Descript (web link)](/export-and-share/share-page) 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)](/export-and-share/share-page) 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)](/export-and-share/share-page) 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. **Tip for desktop app users** If you're on the desktop app, try the general tips below before browser-specific steps. #### 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](https://web.dev/articles/persistent-storage). 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](/app-troubleshooting/performance-playback). * 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](/getting-started/install). This error typically means Descript found a part of your video file that should contain video — but doesn’t. It usually points to a corrupted file segment or a glitch during recording. Our engineering team is aware and working on a fix. The following workarounds can help in the meantime: * **Export from the desktop app:**\ If you're using Descript in a browser, open the project in the desktop app and export from there. This resolves the issue in many cases. * **Download from a share page:**\ If you’ve already exported to a Descript share page, download the file directly from that link. [Learn how to export to a web link or share page](/export-and-share/share-page). * **Re-encode your video file:**\ If the issue persists, use [Handbrake](https://handbrake.fr/), a free open-source app, to re-encode your video: 1. If the video was recorded in Descript, download the source file from your project [via the project file actions menu.](/add-and-manage-media/project-file-actions) 2. Open the file in Handbrake. 3. In the **Video** tab, set **Framerate (FPS)** to **Constant Framerate**. 4. Export the re-encoded file from Handbrake. 5. [Replace the original file in your project](/add-and-manage-media/replace-file) with the new version. [Watch a walkthrough of the re-encode process here](https://share.descript.com/view/GjWYPhv3oA5)
