# Sync Options

Depending upon the output device you are using to view the timeline, the audio and video might not be in sync. Use the Sync Options feature to sync the audio and video. When you enable a sync option, a pre-calculated default is already applied. You only need to enter a value if the audio and video are still not in sync.
