First real project using this software. No video, just stills and one 1920x1080p Animation codec .mov to work with. At first I had choppy playback, but changed the Preview Video type from Quicktime H.264 back to the default and now it's fine. What isn't fine is that the topmost "bar" is almost totally blacked out. Restarting program makes no difference.
