I'm just posting quickly to let people know that VidSync does NOT work yet on MacOS 11 (Big Sur). Apple made some major changes under the hood, breaking some of the underlying technologies VidSync relied on. There are new and improved versions of all of these deprecated tools, and I'm working on implementing them in VidSync. When I'm done (hopefully early February 2021), I'll post a new version of VidSync that should be compatible going forward with the next several versions of MacOS and with the brand new Macs using Apple Silicon chips. In the meantime, anyone actively using VidSync should hold off on upgrading to Big Sur.
