I have a sequence of shots in a ProRes timeline that are at 75% speed (or any speed change). When I render any transitions or title supers I get flashing at the bottom of the frame. It seems to include the last 5 or so lines and has a 4 frame cycle. I've tried dropping the same shots in various timelines (DV, DV50) and the problem is still there - seems it's associated with the source material not the timeline settings. I even re-digitized new source material with the same results. I was able to use a crop of 1 at the bottom of each shot which solved the problem.
Anyone else able to recreate the issue?
