Render Issues

I have created an animated lower 3rd with "Video Box" in After Effects. I must export with "millions +" to retain the alpha channel so I can drop videos into it with FCP. (I will actually be placing the animation on top of the videos, in the superimpose video track, within FCP.)
Problem is my layers do a little "twitch" after being exported. It seems like the lighting changes on a couple frames. It happens in FCP's player and in Quicktime player, but not while I'm RAM previewing in After Effects.
This is a ten second animation exported as animation, 29.97, containing layers assembled in photoshop and swirly stock video "textures". I'm working with a dvc pro sequence in FCP but nonetheless, these files must play smoothly in Quicktime for client approval before I begin any editing. I tried dvc pro codec and even "twitchier" ; )

Hey Dave,
Its still a problem within FCP, but I found a way around it.
Basically, the layers that rendered incorrectly had NO effects, keyframes or alterations whatsoever applied by AFTER EFFECTS. But they DO contain multiple layer styles brought in from photoshop ( newly supported in AE CS3). I just went back into photoshop and had to flatten those styles. Interestingly enough, it seems the "pattern overlay" style from Photoshop specifically does not render well in After Effects. Especially when the pattern is scaled extremely small.
Thanks for your help...you always respond so quickly!

Yeah, watch out for that.
Just like Adobe says AE supports mp3 and mpeg 2 (just don't attempt to render them!) and Open GL (but not completely), you reeeeaaaly have to know which layer styles will work in AE.
I ought to follow Adobe's model and start claiming I can make homemade pasta that's every bit as good as Iron Chef Mario Batali's stuff.
Oh, I can, I've done it... just not every time.
