Corrupted Audio on MP4 files from windows computer
I’m wondering if anyone has encountered a problem with corrupted audio on MP4 video files imported into iMovie. I assemble a video each week on a MacBook Air (with current OS and software) from several video clips contributed by different people. This week, the audio on the two clips that were recorded on Windows-based machines became corrupted when imported into iMovie. The original clips play without issue in QuickTime, VLC, iPhoto, and when embedded in a Powerpoint slide. However, the audio becomes broken up - long stretches of silence interspersed with a few words here and there - when I play the clips within iMovie. I tried opening and then exporting the clips from within QuickTime (and iPhoto and as a Powerpoint slide show MP4 export), and in all cases the programs encountered a fatal error and couldn’t export the segment. A colleague repeated all of this on a different Mac, and had exactly the same problems. We ultimately solved it by importing the segments in question into Adobe Premiere and exporting them there - but I’d love to figure out the cause so that I don’t need this additional step. If anyone has had a similar problem and can offer solutions, I’d love to hear them. Thank you!
