I wish more of this video apps would make iyt hard to record portrate, unless you are filming the collapse of a tall building, at least I feel theat video content is best wide screen (yea I'm old). Correct me if I'm wrong but most screens thatt are not easely rotatable (ie anything but phones, phablets and tablets) are usual wider than they are tall.
I used to think this (I’m probably older than you and come from a broadcast tv background) but vertical video is here to stay and provides many benefits. Today it’s all about shooting for your end device, and even things like theatrical movie trailers have gotten super creative editing trailers in vertical format. I actually enjoy the possibilities it has opened.
