DaVinci Resolve: Syncing external audio with video

Demo summary

Casey demonstrates the 'Auto Sync Audio' feature using waveforms to replace low-quality camera audio with high-quality boom mic recordings.

Step-by-step

  1. Move the external audio files into the same folder as the video clips.
  2. Select the video clip and the corresponding audio clip by holding Control.
  3. Right-click the selection and navigate to Auto Sync Audio.
  4. Select Based on Waveform.
  5. Right-click the header and select Synced Audio to verify the linked file.

Options

  • Batch sync by selecting all clips at once using Shift-select
  • Sync clips manually on a timeline

Watch out for

  • The waveform sync may fail for clips that do not contain dialogue or clear audio matches.

Tips

  • Use the 'Synced Audio' column in the header to double-check that the correct high-quality file is linked.
  • Don't worry if a few clips fail to sync automatically if they don't contain essential audio.

Highlights

What's cool about this is we can actually select all of our clips... and that's going to make editing a lot easier.
