I've got a 60 second .mp4 file that I need to incorporate in my timeline. I tried importing it but Premiere came back and said that it was either a corrupted file or an unsupported file format. I can watch the whole thing with no problem in QuickTime, so I know it's not corrupted. Any tips on how I can get this imported? And when it imports (if it does) will I be able to separate the audio from the video?
