This drives me crazy too and it is embarassing that on iOS after ten versions we still can't easily add a video media file easily. When I am short on time or not on my personal Mac I airdrop a video file to the iPhone/iPad. Sadly it ends up in the PHOTOS sphere, not the Videos app/internal directory. So the play controls are odd and it does not continue playing when exiting out. But it works. Kind of.
