When I try to import some 4K video clips from GoPro Hero5 into the editing software iMovie on Mac, however the iMovie 11 won't import the GoPro MP4 video files. They play fine on Quicktime Player on the Mac, but iMovie refuses to import them. So I goole the question like can't import GoPro Hero5 footage into iMovie online, some positive solutions pop up:
Solution 1. Use QuickTime Pro 7
Convert GoPro files with QuickTime Pro 7 into QuickTime format file. Good luck. iMovie can import the output .mov videos. But it takes long time. And it cost so much quality.
Solution 2. Transcode GoPro Hero5 4K Videos to AIC for iMovie

So I try the convert GoPro Hero5 4K Videos to iMovie edit-friendly format via third party video converter. To finish the task, Brorsoft Video Converter for Mac is highly recommended here.
