Syncing Audio to Video
by Matching Waveforms
If you don’t have matching timecode in the audio and video source clips you’re syncing, but you
had the foresight to record camera audio at the same time as the dual source production audio
you want to sync to, DaVinci Resolve can use waveform syncing to compare the audio
waveforms of your audio and video source files, and sync the ones that match.
To batch sync dailies using waveform syncing:
1 Create a new project, open to the Media page by default, and import both the video
and audio media you need to sync. There’s no need to organize your files in any
particular way, but it’s not a bad idea, on multi-day shoots, to organize the audio and
video files so that it’s easy to select all of a single day’s clips at once so that you can
sync your files in smaller batches. Even organizing your clips by scene can make
waveform syncing go faster by reducing the number of files that need to be compared
at once.
2 If you’ve placed the audio and video into separate bins, then you can Command-click
both bins in the bin list to select them and expose all of their contents in the Media
Pool. If you placed your media in the same bin, this is not necessary.
3 Select one of the exposed clips in the Media Pool, and press Command-A to select all
audio and video clips you want to sync.
4 Right-click one of the selected clips, choose Auto Sync Audio from the contextual
menu, and select one of the methods below.
Based on Timecode: Synchronizes the timecode between the audio and video clips,
and replaces each video clip’s previous audio channels with the newly synced .wav
files.
Based on Timecode and Append Tracks: Synchronizes the timecode between the
audio and video clips, and adds new channels in addition to the audio channels that
were previously in the media file. The newly waveform-synced channels are added
to an additional track, so when edited into the Timeline, a clip that’s synced this way
appears with one video clip and two audio clips that occupy two different audio
tracks, so you can edit the camera original audio independently from the synced
audio.
Based on Waveform: Analyzes and compares the waveforms of each of the selected
clips, and replaces each video clip’s previous audio channels with the newly synced
.wav files.

A progress bar dialog appears, showing you how long the syncing operation will take.
When it’s complete, your clips will be synced.
