Game capture is pretty slick. We saw a marble maze game get instant capture of the last 30 seconds of buffered frames from a simple voice command. Xbox One's Upload Studio had a 720p 30fps clip waiting immediately after. Users can quickly edit, save, or share this clip with further commands. Another voice command can have you back in the game just as quickly.
Penella says that these clips will only be able to be shared on Xbox Live at launch. They'll have social sites like YouTube and Facebook set up for sharing by next year.
I know this was touched on in a different topic but isn't this a big deal? Might as well not be there till you can share it outside the console for some.
