Am having extreme difficulty getting the 3D effects to line up correctly when trying to switch between clips.
Have both clips on same timeline and drag and drop transition over both, so far so good . But when you play video (Using spinning cube as example) the cube starts to spin with clip A showing, but then either both visible sides switch to clip B (so you see the switch over), or spins so only second side visible which is showing clip A still, and then just flicks over to clip B.
I have adjusted the length, position, start points of the transition with no joy. Some of these clips have been spliced to take out some of the crap and I am wondering if this is a bug as it has not recognised this :
Please help as it is driving me insane

try unchecking 'pin to clip' in source window menu
