This article offers troubleshooting steps to resolve sync issues in Descript. Whether you're dealing with playback sync issues or problems with exported files, we’ve got you covered. Follow these steps to keep your audio and video aligned.

Check your original file

If you recorded your media outside of Descript, audio/video sync issues may stem from the source file itself. Try previewing it in your system’s media player. If the file is out of sync:

• Re-export the file using the same settings.
• Try a different export format or encoding.
• Contact the third-party app or hardware manufacturer for help.

Try adjusting sync in the media preview modal

For consistent delays or clips that start slightly out of sync, shift the audio/video sync without editing the timeline or entering a sequence:

• Open your media from the Project files panel, then click the options menu next to the file name. Choose Set A/V sync offset.
• In the media preview modal, use the sync slider in the bottom-right corner. Apply a positive value to delay the video, or a negative value to advance it.

Bluetooth playback appears out of sync

Using Bluetooth headphones can sometimes cause sync delays during playback. Try switching to your computer’s built-in speakers or wired headphones. In most cases, your final export will be properly synced even if in-app playback appears delayed.

Use the built-in Repair file tool

Descript includes a Repair file feature that can automatically correct timing issues in some media files.

Manually fix sync in a sequence

For precise control, you can detach the audio from a video clip and manually realign them in a sequence.

To do this:

1. Right-click the media clip and select Detach Audio.
2. Right-click again and select Edit Sequence, or use Cmd + Shift + O (Mac) / Ctrl + Shift + O (Windows).
3. Use the Select tool in the sequence to drag the audio clip into alignment with the video.

You can zoom in for frame-level precision while editing in the Sequence Editor.

A note on hardware latency

If you're using external audio or video equipment, sync issues may be caused by hardware latency. Try recording with your computer’s built-in mic and camera first to rule this out.

Then, reintroduce external devices one at a time to isolate the issue. If latency appears with specific configurations, contact your device manufacturer for troubleshooting tips or driver updates.
