Can you give us more details about your system and Premiere version ect.. See this link for reference.
Sure. Sorry about that.
Premiere Pro CC (up to date)
Win 7 64bit (up to date)
NVIDIA 470GTX (driver up to date)
4 x 1.5TB internal
USB 2.0 and 3.0 drives
FireWire audio device (M-AUDIO FireWire1814)... although, I am not using it for playback. It is connected.
Footage is from C100 H.264 .MTS, H.264.mov from 7D, PNG.mov (with alpha) and photoJPG.mov from AE.
I have some Magic Bullet effects installed.
I am using a
All footage is 23.976.
I would be happy to record a screencast of the problem, if you think that'd help.
Something you might want to try because of the complexity of your multi layers is Nest some of them or create a digital intermediate of some of them. D.I
This I created a nest of the layers in question and it is still happening. I even tried to apply the AL with the same effects to a photoJPEG.mov file and it produced the same result.
BTW - these effects work perfectly fine when applied to a clip (the photoJPEG.mov worked perfectly with the effects applied directly to that clip). As soon as I apply it to a AL it goes nuts.
Post a screen shot of the issue. I can't really 'see' it in my head with the description alone.
I think your alpha channels are cancelling each other... or maybe either of them.
