Funny how panoramic/horizontal arms race between film producers and TV producers calmed overnight. I was prepared to ask a snarky question about vertical movies going mainstream but apparently there has been already a relevant festival since 2014.
It's one thing for a video to just be in portrait, but another for a video to be in portrait letterboxed to widescreen..
What do you think about watching portrait video letterboxed to widescreen on smartphone held vertically?
