Google announced a slew of new features at this year's VidCon. After giving the treat for high-quality 4K Ulta-HD video streaming to users, Youtube is all prepped-up to make available streaming support for high-frame rate (HFR) videos at 48 and 60 FPS. With all the new clarity and loss of "cinematic look" on higher frame rates, this would be a feature best suited for video game footage and trailers. Apart for this, Youtube will also enable fans to contribute money to channels and support them, allow uploads of fan contributed video subtitles, better Annotations in form of new interactive information cards which uploaders can program to work across desktop, phones and tablets and more ways to create and generate playlists.
Youtube team has also made available a playlist of these high-frame rate videos as shared below, make sure you watch them in HD quality to load the HFR version.
