One thing I do have to commend Quibi for, however, is how well they reversioned their video content. I think they will be seen as a little ahead of the competition there (possibly before their time). Against other content houses that will have significantly more footage to get through (and/or less resources for this task).
I think the different versions (e.g. portrait/landscape for Quibi) will be a little way off being that common. I expect computer vision tooling will enable it more broadly when it can at least expedite the process considerably (which probably isn't a huge distance off although then the blocker is organisational processes around publishing video).
