I have a project with c70 mxf files - half of which are shot in clog2, the other half are shot in bt709.
Each type of files works fine on their own, but if I import both into a project, the bt709 files get glitched - the footage "flickers" between displaying correctly and being washed-out/grey tinted. These glitches appear in both the source mointior, the project panel previews, and the timeline. They are also there when I export.
I asume this has something to do with colour space management - I went back to V 15.4.5 and the problem is gone.
