Audio and video can drift out of sync on playback or in an exported file. The steps below help you line them back up.
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.
For consistent delays or clips that start slightly out of sync, use Set A/V sync offset to shift the audio without editing the timeline or entering a sequence. Learn how to adjust A/V sync offset.Offset slider in media preview modal
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.
Descript includes a Repair file feature that can automatically correct timing issues in some media files.
For precise control, detach the audio from a video clip and manually realign them in a sequence.
  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 to drag the audio clip into alignment with the video.
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.
