MP4 files not showing up in iMovie
I'm trying to import mp4 files into iMovie using the import function from the File menu. After creating/naming a new event, iMovie shows a quick import script and then stops. Afterward, nothing is visible in iMovie to edit; no thumbnail, no video, no file.
When I check in the Finder under 'Movies' the iMovie events show up with the full files (shown multiple times from multiple imports), but I still can't see anything at all in iMovie to work with.
Am I missing a simple switch somewhere?
