Tips to Troubleshoot Audio Sync Issues

Even after syncing the clips in DaVinci Resolve, the audio gets out of sync during editing, or clips may not sync automatically. Understanding and addressing these issues is essential to perfectly aligning the media. So, here are the troubleshooting steps to remove the problem and improve the smooth syncing.

  1. Audio out of sync after Syncing

Sometimes, the audio would go out of sync even after syncing the clips, or you may experience a different pitch. The issue arises when there is a slight difference between the clip and timeline frames or sample rate. So, the video will play faster than the audio clip. 

To fix the issue, go to the “Project Settings” and adjust “Timeline Frames” and “Playback Frames.” Then select clips and open “Clip Attributes” to change the clip frames. Additionally, pitch and speed controls from the “Inspector Panel” will be used to adjust the audio duration.

  1. Auto Align Clips is Unavailable

The auto-align clips feature becomes unavailable after importing multiple clips in the Timeline. Also, if there is no space between the added clips, it will be difficult for Resolve to sync them in the Timeline. So, it’s best to sync the clips in the “Media” tab and then import the synced clip in the Timeline. 

  1. Keep the Audio Loud

It’s necessary to use loud audio for smooth auto-syncing “Based on Waveform.” If the audio from your camera is not loud enough, then the Resolve will be unable to read them. DaVinci Resolve analyzes the waveform from your video or camera files and audio clips and matches them up. So, during production, keep your audio loud enough so Resolve can effectively analyze and sync the clips.

  1. Sync Clips Manually

Aligning your clips is time-consuming, but it ensures smooth syncing of the clips. Sometimes, the auto-sync feature does not provide a uniform alignment, so it’s necessary to sync using waveform manually. Also, minimize the background noise because it hinders sync point analysis.

  1. Update the Software

In DaVinci Resolve, some features become unavailable after updating for various reasons. The update might introduce new bugs or compatibility issues with audio and video clips during syncing. So, carefully analyze the feedback before updating, revert to the previous version, or update again to the better version.

Conclusion

DaVinci Resolves’ user-friendly interface and powerful features make it essential software for audio and video synchronization. It simplifies the syncing process with its “auto-syncing” feature, saving time and providing high-quality clips. It also enables you to sync multiple clips for a smooth experience manually.

So, along with syncing, understanding the tips and tricks is essential to enhance the quality and seamless synchronization of the clips.
