QT HD video from After Effects

I am trying to make timelaps videos from pictures in After Effects CS3 on a PC, for export to Vegas on PC and FCP on MAC. And After Effects gives me a lot of export format choises in QTime.
I live in the PAL world, so what HD format (Compression) gives me the best result at a decent filesize?

if there's no interlacing, my vote would be
PhotoJPEG set to 75% (4:2:2), or
PhotoJPEG set to 100% (4:4:4) if title cards, etc, were added.

caveat
gamma *might* have to be adjusted in FCP using this format; can't remember if FCP handles PhotoJPEG as RGB or YUV. Graeme Nattress (and others) have written about this, but i'm drawing a blank as to where.

Thanks Rob, for your reply.
I will have a try at PhotoJPG. I also have a sequence shot in front of a bluescreen, but PhotoJPG do not support alpha channel, as far as I know. What are the alternatives there?

uhhh, good question...

i'd probably pick QuickTime-PNG if i needed lossless compression and an alpha.

not speaking from experience on this; just what others have mentioned elsewhere... but yeh, this is the route i'd take the more i think about it.

PNG and Quicktime (animation) will retain the alpha channel.
