I just bought a GoPro Hero 3 Black Edition. I have been testing out two modes: 1080p at 30fps and 720p at 60fps.
I have noticed that when reproducing the videos with 720p at 60fps they are not really smooth, they seem a little bit weird (I have used VLC to reproduce them). So, a friend of mine suggested me to convert them to 30fps and then they will be slow motion, and later on speed them up 50% with Adobe Premier. After doing that, they look better.
I am confused. Why does this happen? Why do I need to low them down to 30fps and then speed them up up to 50%? Wouldn't that mean that we are back to 60fps?
