YouTube blew more than a few minds last October when it rolled out 60 frame-per-second video playback on the site. Gamers especially flocked to the frame rate as it allowed for jutter-free playback of fast-paced titles like Call of Duty or Titanfall. Today, YouTube announced a new feature that is sure to make gamers even happier: 60 fps live streaming which will allow people to broadcast their online exploits in real-time. The new frame rate is still an early preview, mind you, and will only be available on HTML5-compatible browsers. However, YouTube will encode these streams in both 720p60 and 1080p60 formats as well as automatically knock it down to 30FPS for devices that can't handle full speed.What's more, YouTube is also rolling out HTML5 playback which will enable viewers to not only rewind in the middle of a live stream but also play it back at up to double speed in order to catch back up to the broadcast. And for producers, the video-sharing site has collaborated with Elgato and XSplit to ensure that products like Elgato Game Capture, XSplit Broadcaster and XSplit Gamecaster will continue to work with the site.
