The screen dimensions of a mobile phone
don't happen to coincide with the best/most pleasing aspect ratios for viewing pictures and video. They have a similar aspect to a closed book. To get the most out of your book I suggest you nearly double its width by opening it.
Some early engineering review films of NASA rocket launches were filmed in widescreen with the rocket angled from far corner to corner, but AFAIK they were not meant to be viewed upright or on a rotating screen, they were designed to be played back on a standard projector in widescreen because NASA are not MONSTERS.
Also in a rocket launch, the rocket typically spends most of its time in a horizontal orientation. You could take a nice still of the rocket on its launchpad in portrait, but video of a launch in that format would be nigh unwatchable.
