YouTube 60fps

Late last year YouTube began supporting videos at 60 frames per second, twice the normal 30 fps. This is particularly useful for video games, but I can see the differences in the fast action scenes on this Avengers, Age of Ultron trailer, very appear to flow better.  Be sure to change the video mode to one of the HD options to see the best quality.
