For most YouTube videos, frame rates of 24 or 30 FPS are all a creator needs to produce an easy-to-watch clip. However, YouTube gamers in particular are fond of the 60 FPS format; that frame rate gets rid of the jumpy, laggy image quality, a common problem which plagues creators trying to record game footage, especially on games meant to be viewed at higher definition.
YouTube already introduced 60 FPS video support on its website back in October 2014; the high frame rate is also available on the YouTube app for Apple TVs and PlayStation 3 and 4 consoles. Later, Google’s online video hub started to allow live streams in 60 FPS, as well; some outlets believe that move could be part of YouTube’s strategy to update its live streaming capabilities and take on Amazon-owned Twitch.
VentureBeat notes the 60 FPS video support for YouTube’s mobile app does not include support for 60 FPS live streams. However, the update is being made on YouTube’s server side, so if you already have the iOS or Android app installed, you won’t need to re-install it to start watching crystal-clear videos on your phone.
