Actually, I just found a similar post with my problem and I just downloaded the new DNX Le codecs and it gives me the ability now to add an alpha.
Thanks

Hey KEVIN –thanks for the reply — My seting were all correct (the same I’ve been using for years) — I will try straight unmatted and see what we come up with — I’m just worried that using straight umatted with transparencies will make the gfx look like crap
