Step 2–Sync Audio to the Dailies
If your video format has embedded audio, DaVinci Resolve can simply pass that audio through
when outputting media from the Deliver page. However, if the program you’re working on
employs dual-system audio recording, there are a variety of methods available for syncing it in
the Media page. You can also import timecoded Broadcast WAVE files into the same bin as the
accompanying video clips (you can place them into a sub-bin if you like), in preparation for
syncing the dailies in DaVinci Resolve. Once you’ve imported the video and audio media you
want to sync into the Media Pool of the Media page, you can right-click the enclosing folder and
choose “Auto-Sync Audio Based on Timecode” which automatically syncs every timecode-
matched pair of audio and video media clips within the same folder, all at once. Alternately, you
can choose “Auto-Sync Audio Based on Timecode and Append Tracks” to add the synced
audio tracks to any audio tracks already present in the video clips.
TIP: For the best results, consider using different folders for each day’s audio and
video clips.
If you don’t have synced timecode, but your video clips have separately recorded audio (usually
via an on-camera microphone) that matches the dual-system audio recordings, you can use
waveform syncing to quickly sync each video clip with its matching audio clip. Import your
separately recorded audio files into the same bin as the accompanying video clips (you can
place them into a sub-bin if you like), in preparation for syncing. Once imported, you can
right-click the enclosing folder and choose “Auto-Sync Audio Based on Waveform” which
automatically syncs every timecode-matched pair of audio and video media clips within the
same folder, all at once. Alternately, you can choose “Auto-Sync Audio Based on Waveform and
Append Tracks” to add the synced audio tracks to any audio tracks already present in the
video clips.
TIP: With waveform syncing, for the best and fastest results, consider using different
folders for each day’s audio and video clips, or even different folders for each scene,
to reduce the number of waveforms that need to be compared at one time.
Finally, if all you have in the way of sync reference is a humble clapboard, you can manually
sync video and audio clips by selecting a video clip to open into the Media page viewer, and
then clicking the Waveform button in the Audio panel and clicking the corresponding audio clip
to show its waveform in the audio panel. In this way, you can drag the Viewer and Audio panel’s
playheads to the video and audio sync points, and click the Audio panel’s link button to lock the
A/V sync of that clip.
For more information on syncing audio and video in the Edit page, see Chapter 14, “Modifying
Clips and Clip Attributes.”
