Once you have grouped your sources into a multicam clip, timecode will align your sources with perfect synchronization. However, more often than not there may be a slight synchronization offset between those sources for a number of reasons, including  improper jam sync clocking issues on the source or simply timecode with various start points. To fix and solve this issue, Blackbird provides a manually adjustable sync method.

To sync your sources embedded in your multicam clip. Load your clip in the source viewer or force a source viewer by drag and dropping the multicam clip to the desktop

Right - Click on any thumbnail, and select Sync Multicam

The Timeline will automatically switch to a special sync mode timeline which will show all associate video and audio clips represented as sync map tracks

Clicking on any thumbnail and playing the video will play all the video source, and you’ll be monitoring  the selected source audio track for reference

Click and dragging left and right on independent video track sources will slip the selected track. 

This is useful when zoomed in if you have a visual sync such a smart slate, clap board or even a hand clap. 

If you don’t have a visual sync point, you will need to use the audio tracks for synchronization. 

In this example, identical audio was recorded to each camera, which makes it very easy to identify the clips that are slightly out of sync. 

In this example, 2 of the cameras have all the audio feeds and 2 of the camera have isolated feeds, so the patterns have to be identified. Monitoring tracks by playing a reference area will help with this process for re-syncing. 

Once the camera sync is established, using the close button will close sync mode and a new sync relationship between camera is now locked. You can reestablish new sync be simply re-opening the sync mode at any moment. 

In our next tutorial, I will discuss logging multi-camera content.
