You know, I can’t remember. After looking at the export options in AE, I suspect I simply exported everything as a Premier Pro Project.
I didn’t see any loss, but I don’t know that I looked that hard either. This particular project was super small and my client wanted a lower res version anyway.
I’m sorry I can’t be of much help beyond that. I think I dug up that suggestion on a random DV forum somewhere. In the end it worked great for me, but the project required little editing save for some keying so it might not be the best solution for everyone.
