Some say the human eye can't see above 30fps. See for yourself.
These are not Gifs. They are MP4 videos. Both TRUE 30 & 60 fps.
If the videos are off sync simply reload the page by pressing (F5) after the videos have loaded
> Stare at the left 30fps clip for a a few loops then look at the 60fps clip on the right. <
