I am trying to build an effect that has keyable banners on the front and back side of Key 4, running from separate VIZ channels, and 2 different videos on the front and back side of Key 3 running from separate TONS channels. I have built 2 sequences to rotate both of these keyers at the same time (for use in a tease, hot open, etc..) The one problem I have run into is that when the video from the backside rotates to the front, it does not roll automatically. Is there anyway to force this to roll like videos normally do, or do I have to do something tricky where I have the video punch up somewhere on the MLE where it won't be seen, but will get it to roll?
