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.

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.
