I have had no problems downloading my gopro hero 2 videos to my iphoto or external hard drive, but as soon I get the hero 4 the videos are glitchy after being down loaded. Do I need to get a newer computer to keep these from being glitchy because it can't fully compress the file? Or is there a program I can down load that would smooth out the videos?

Anyone else had this problems with their hero 4 videos being glitchy?

Thanks in advance! I got some great videos in powell this week and I would really not like to lose the videos.
