All synced clips appear with an audio icon at the bottom left in the Media Pool when Thumbnail view is selected. Now that the clips are synced, you can edit them in the Edit page or use the Deliver page to export offline dailies or online media with embedded sync audio for use in other applications.
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.
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.
