You may have to import and convert it to an MOV file using GoPro Studio. Pretty easy. I'm surprised it won't upload to YouTube. That site converts/compresses most any file.Well, I made the video, but for the life of me cannot upload it...anywhere. I've tried directly to this site, youtube, and photobucket. For some reason, I just can't get any to take it. It's only 1:10. Used GoPro 4 Hero. Any ideas?
