Why Can't I Output Video From iMovie?

Episode 1634 (2:12:20)

Howard from Sherman Oaks, CA
iMovie

Howard is having trouble with iMovie. He can't share video from it. It's constantly a compressor error. Leo says that iMovie has to render a video file using Apple Compressor. There may be a damaged file. There was an update this week, so check to see if that fixes it. If it doesn't, try uninstalling and reinstalling. Make sure to delete the compressor file and then reinstall it.
