Re: EX1 footage supported in AE for Mac? by Amit Zinman on May 20, 2008 at 6:49:14 am
You should probably update your After Effects and Premiere to the latest version to get the support you need. Also, working with an intermediate format is probably best. I would export bit and pieces to qt Animation if I were you.

Dave's Stock Answer #1:
If the footage you imported into AE is any kind of the following -- Native HDV, MPEG1, MPEG2, mp4, m2t, H.261 or H.264 -- you need to convert it to a different codec.
These kinds of footage use temporal, or interframe compression. They have keyframes at regular intervals, containing complete frame information. However, the frames in between do NOT have complete information. Interframe codecs toss out duplicated information.
In order to maintain peak rendering efficiency, AE needs complete information for each and every frame. But because these kinds of footage contain only partial information, AE freaks out, resulting in a wide variety of problems.
