Hi all, first time poster so I hope I dont ramble but I was wondering, what are some ways that I can run after effects at a fast speed when doing motion graphics and editing HD footage on an Ibook g4 with 1.42 GHz and 1.5 GB of RAM? Also If this info helps I have a ATI Mobility Radeon 9550 graphics card with 32mb vram and 17.51 GB left on my 55.77 Hard drive. Anyway like I said, first time poster so I hope i didnt do anything wrong. Thanks to all who help!
