An update releasing today will make uploading gameplay clips to YouTube a seamless process. Content can now be captured with the Game DVR app, subsequently edited in Upload Studio, and once finalized, shared directly with a linked YouTube channel. This simplification now allows more users the wherewithal to reach a larger audience in an easier fashion.
In addition, the update brings with it the ability to view YouTube videos in Snap Mode. Aside from the countless strange juxtapositions possible, like Titanfall and keyboard cat for example, this feature can be useful in watching game walkthroughs while simultaneously playing that game. Finally, users can now pin favorite YouTube channels to the One Guide for easy access, making it quicker to get to subscribed content.
