I’m not quite understanding the workflow or the reasons for it but you can always lay off to to tape and bring that into FCP with no worries. Depeanding on your Avid, I’d venture to say that too is lower field first so that may be your bottleneck. Of course, Avid’s QT reference files are aliased as all get up where precomutes are unless ya mix it down first so that too may be the problem. I’d export as uncompressed Quicktimes if adding the time and expense for this workflow.
The way ya did it the first time is how ya handle old school matte and fills. Can they not just give you a finished graphic with an aplpha channel in tact?
I can’t see the bouncing you mentioned so it’s hard to say.
Over and over you’ll find After Effects is yer buddy and Marquee never was. It wasn’t made and released to be used so much as verbal defence when folks bash the primative title tool.
Make sure you are importing it at 1:1.
The uncompressed meridien codec will work fine. Don’t rezize upon import (I’m thinkin that’s it). Use the first selection (601) in your import settings. Invert the alpha and you’re golden. You’ll wanna monitor on a real monitor… not just your computer screen.
The quickest easiest way is to just animate some masks revealing the color. A far out groovy way would be to shoot some dropped dye in some water, key that over the B & W shot and on another layer do the same but make the fill the color shot.
It’s on the right side of your effect menu. You’ll see crop, cornerpin, rotate, scale, ect. They are little icons.
Blow the dust off the ole manual if ya have to.
