I just tried out my new gopro4 silver after upgrading from the hero 2 didn't exactly get the results I was expecting. The footage while ultra clear had a weird stuttering effect. Settings were 1080 x 60 fps superview, protune on go pro colors. Was mounted on paddle shaft. Maybe vibrations through shaft? Seemed to be worst when traveling fast . Didn't convert files to mp4 just copied to pc and iPad had same results on both. Any ideas or settings would be appreciated. Will upload video when have time thanks.
