To back up a bit, I’ll explain how I usually work with GoPro videos. I also couldn’t import converted video into iMovie anymore.

After doing so, I realized that all my previously-imported GoPro videos wouldn’t play in iMovie anymore, showing as “empty” tracks instead. I recently upgraded my MacBook to OS X 10.10 Yosemite, and at the same time accepted the automatic upgrade of iMovie to version 10.0.0.6. Recently, I’ve been enjoying using my GoPro camera with iMovie to put together silly little videos. Update June 25, 2015: iMovie 10.0.9 has been released which fixes the problem I describe below.
