I mostly work with sony A7S XAVCS 50 fps files.
All was fine with FCPX 10.1.4, but since 10.2 update here's the issues I've noticed:
— really poor performances and very sticky project timeline / playback compared to the previous version of FCPX (takes ages to start to play, and get sticky, and skip frames, specifically on each cut point in a project)
— lots of FCPX crashes (Pixel Film Studio Prolumetric is unusable anymore) and deal breaker bugs (Neat Video Noise Reduction gives outputs Black Clips*) with third party plugins
Am I the only one to experience those kinds of regressions in my workflow **?
Could Apple address these issues really quickly?
(I'm in the middle of a project I should deliver at the end of this month and start to get quite anxious about the situation).
PS: I've pushed the "update all" button on the App Store, in a middle of a serious project... my bad.
