Youtube does this awful full screen transition animation. How do I turn it off?

After reinstalling OS X, I noticed Youtube goes through the trouble of doing an annoying transition animation to get into fullscreen mode. It didn't used to do that before. I liekd it better when I pressed the fullscreen button and the video just went straight to fullscreen mode.

I noticed that this happens with videos that load in the HTML5 player but not with those on the Flash player. So if you want to get rid of the animation try opting out of the HTML5 trial to see if the full screen animation goes away:

It also happens on the HTML5 players of Vimeo and Dailymotion. It is likely an OS X level issue, given that it seems to use Quicktime to play the videos and the switch to fullscreen animation is tied to it.

It is very annoying I agree, not just in this case but in every single OS X app that supports full screen.
