One note though... Someone correct me if I'm wrong. But the Xpression After Effects Plug-In does NOT work with Mac computers. So even if you did have it, it would not work. Does anyone know if this has changed? As far as I was told, the Xpression After Effects Plug-In would only work on Windows Computers (NOT MACS). If anyone knows if this has changed please reply to this post.
As for you using the animation codec. Xpression will read Apple Pro Res 422 (video only) files and it will also read Apple Pro Res 4444 (video + key) files. These formats are smaller file sizes than Animation and may make it easier to transfer. You may still need to convert with the Xpression Video Coder but should not take as long.
Hope this helps
Cheers
PS if you are on a windows computer with Xpression installed, Adobe Media Encoder is a great way to BULK convert clips into Xpression format.
