As part of the March update for Xbox One the feature for taking screenshots went live. This feature is, for now, only available to members of the preview program but it will likely not change much when available to all users.
Already some beautiful shots have been posted on reddit by user 'TastyBread' and it shows us some beautifull panorama's and gameplay shots of Halo 4 and Far Cry 4.
Question out of curiosity since I didn`t try it yet. Any way to map the function to a button or does it only work via the voice command?
I think you double tap the x box button and push x to record or y to save screenshot.
Still not used the video function yet I take few pics on steam but not many so this will not get used by me at all handy for people who like to share I guess.
