I just got my iMac about a week ago, and I've been hoping to try out Adobe Premiere Pro CS3 on it. I used to be a WinXP user who lived on Win Movie Maker for making my little music fan vids of my fave TV series. I recall having to convert most of the vids to wmv format inorder to create the vids. Is it the same with Premiere CS3 or even CS5? or iMovie? I tried importing the videos and all that comes out is "error. codec not available" If I do have to convert the videos, to what format? for iMovie? for Premiere? Sorry if I have too many questions, but I'm really new to all this. I just switched... Thanks for any advice you can give!
