Since update of FCPX 10.2.1, plugin has either showed a black screen in preview or video below the video that the filter has been applied to (Show A-roll Clip instead of B-roll clip). I was using version 3 and thought that purchasing version 4 would solve problem, but that didn't fix it either, after downloading and installing. Any ideas on how to get it working again?
I just did some more testing. Restarted FCPX erasing the prefrences. Created a new project. And used the old clips and it works great again! I guess killing the pref. make the difference. Not sure why that made a difference, but glad to see it working again.
