How do I make my video quality 720p60 or 1080p60 on YouTube

[MEINKRAFT]

I am one of those people who is crazy about fps. I saw this new feature on YouTube where you can view a video in 720p60 or 1080p60 which is pretty much hd in 60fps. I was wondering how I could do that. I use mirrilis action to record and sony vegas to edit and render. Thanks for your help.
