Rendering screws up track matte.

Tried turning the GTX 570 off. Made no difference.

Evil Edison at the Adobe forum came up with the solve. I had to create a video track with black on it under the source video track being track matted.

Yes, stacking order is important for a track matte effect in Premiere Pro. Glad you solved it.

Kevin, from what I experienced, it wasnt really the stacking order that was the problem (as far as I can tell), it was the need for a black slug to be placed under every video that was being track matted.Not a very intuitive way to do things. Why does it need the black slug on the bottom?

1. Top layer – Rampant Design animated track matte with alpha
2. Middle layer – Video with PrP track matte effect assigned to it.
3. Bottom layer – black slug

Can’t thank you enough Tom! I’m facing the same issue right now in PRP. It makes no sense as for two seconds the matte does not work for the whole screen, but then it corrects itself. Regardless it works the way it is supposed to now, thank you.
