I capture and edit fine with real time playback in premiere but in after effects I can't even scrub through the timeline with my footage without having to wait 5 seconds or so for the footage to load in the preview window. I've been searching around for answers and I read that after effects has a hard time reading mpeg footage, so I imagine I should export from premiere to something other than mpeg? I'm running a PC, quad core with 4 gb of RAM so am pretty surprised that I can't get any type of decent preview in after effects even when the resolution is set to quarter. Any advice? I really do appreciate any help.

Dave's Stock Answer #1 For Current Footage Woes:
If your source footage is any kind of the following -- Native HDV, MPEG1, MPEG2, mp4, 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.

That's what I was thinking. Thanks for the tip. Is there a certain codec I should use? I normally use quicktime but I can't find it in any of the export options in Premiere and was wondering if I had to buy it or not?
