I'm using premiere CS3, and the latest version of the decklink software with my multibridge. I'm rendering out a bunch of transitions in a timeline using matte keys. I have layer 1 outgoing video, layer 2 incoming video, layer 3 matte wipe and layer 4 overlay. When I render these in a 29.97 blackmagic SD project, i'm getting some stuttering. I've placed a numbers count file in the timeline to try to see what's going on, and it looks like from time to time the video layer at the bottom freezes for 1 frame. You can clearly see the timecode numbers jump from 2, to 4 with a double frame in between. I'm not sure what's going on, but I've tried everything to get rid of it and I can't. I'll try to post a test project when I can organize it, but I thought someone might know what's going on?
