YouTube announced yesterday that it's working on several new features. First up and perhaps most excitingly is that YouTube is working on support for higher framerate videos. At present, all videos on YouTube are 24fps but in the future it will be possible for everyone to upload clips with a framerate of 48fps and even 60fps. Motion-intensive clips like video game and sports footage should benefit greatly from this. There are some example videos available on YouTube that demonstrate the benefits of 60fps but it's unknown when this feature will be rolled out to the general public.
Also new is a tipping jar, viewers will be able to show content creators gratitude by tipping them any amount between $1 and $500. YouTube will also be supporting "Fan Subtitles", a crowd-sourced translation effort that encourages multi-lingual users to type in subtitles for their favorite videos.
Last but not least, content creators will get access to "YouTube Creator Studio", a mobile app that gives instant access to all video metrics.
An example of a 60fps video can be seen below:
