(to start, this is a brand new Mac Pro) For my work, I had to take a bunch of Mpeg2 files from a guys camera and edit them into a short movie. Well, the mpeg2 files wouldn't load in iMovie as they were, so I got VisualHub to convert them into DV files. The files converted fine, and the new DV files will play in Quicktime, but when I drag them into iMovie, the show up with the thumbnail and I can see the movie preview still, but when I try to play it in iMovie's preview window, it's just a white screen with audio. I tried exporting it from imovie then, and the exported movie will play in Quicktime as well. I dragged that movie into the iMovie window and it loads in the timeline. I can movie the cursor back and forth and see the movie in the preview window, but when I hit play, its back to the white screen and just the audio. At one point, iMovie was working (I think) with these videos. But yesterday at some point, I installed the DivX software so I could view a bunch of .avi files that I had. Those worked, but I think that might have been what caused imovie to stop working properly. So, I've tried removing the DivX codecs from the library/quicktime/ folder, and that didn't do anything. Also, there is a DivX icon in my System Preferences I can't remove either. So, to try and remedy this, I downloaded some recommended codec packs for Intel Macs. This hasn't seemed to change anything. So, here I am, stuck trying to make this movie work in iMovie and have no idea what to do. Anyone have any ideas on this?
