I am having the same exact issue right now creating multiclips where the audio jumps 5-10 seconds out of sync with a documentary I am working on. It’s a two cam shoot using a Canon 5Dm2 and a Canon 7D shooting at 23.98, and recording the audio separately with a Tascam DR-100. I’ve worked with this setup before and have been able to sync both video sources and the separate audio source by using out points (as mentioned above) at our common marker and then creating a multiclip.
However, now I am running into the same issue described in this thread for the first time and am not sure what is different between this project and previous projects where I have done the same exact thing. PluralEyes is able to sync all three clips perfectly, but when I try using PE to create the multiclip, still the same thing. This isn’t a frame rate issue, but some type of bug in FCP.
I did try the “audio subclip fix” but to no avail. Does anyone have an idea what may be causing this?
