There is Twitch support for Xbox One and Playstation 4 where you can video capture whichever game you're playing without having the need to use the video capture device and then upload to that website but the only downside is the time limitation. It may look like a good move overall to me as YouTube itself is already fucked up and corrupted with some stupid Copyright ID Claim disaster thingy. What made that change from YouTube stupid though is that even certain of your gaming videos will be mis-claimed of the Content ID thingy even if they won't contain any single non-gaming content at all unless your videos contain some licensed contents like licensed songs for example, then there may be a risk that your videos will contain the Content ID claim that you can't blame YouTube for that.
So, why YouTube video upload feature for Xbox One? Maybe the service is still popular even today as if we don't know much of other video sharing sites like Twitch, Veoh, Dailymotion, etc. The serious downside nowdays as stated above is the reason you may want to switch to Twitch no matter which console you're playing. Hopefully, we can see some time limit extension for Twitch for consoles like having a 30-minute gameplay video which may be useful for arcade games ported to Playstation 4 or Xbox One but not the other styles of video games that take you longer than that time to complete.
If there's Nico Nico Douga direct video capture and upload feature for game consoles in Japan, they can use it instead of YouTube as the videos may look sharp and smooth at HD 60fps.
