I have an iMac at work, its a year old, I believe, and it has been having problems. To me it seems that the version of Final Cut on this computer will not open any file that is not a .mov, .aiff I thought that Final Cut could open .avi, .mp3, .mp4 but this one cannot. To get to the point is there some thing wrong with the Mac or does Final Cut just no support these formats? And if it doesn't is there a quick and fast way to convert files from .mp3 to .aiff? I know quicktime can do it but it will not be fast. I have about 12 files to convert. Thank you for your help.
