I installed after effects 7 (which is free) and just tried to make a few things in it. When it comes to rendering, it takes about an hour for 6 minutes of video material. I looked at my cpu usage and it wasnt going about 25%. I googled it and found the solution: enable multiprocessing. Okay, everything is fine, the only problem is: I cant enable it. If i go to edit>preferences there is nothing about CPU or so. There just are the memory preferences. I'm running the german version of AE (if that is the reason). I patched to 7.0.1 and it didnt work too.
Oh, by the way, my system is good enough to render and run AE: Quad Core 2,8GHz 4gb of ram
Any help?
