I'll always hate vertical phone videos. So much eyewitness news footage is badly goofed up thanks to people who can't manage to hold their phones sideways. Vertical video captured by a phone is okay when played back on a phone held vertically. But the video sucks @$$ played on anything else, be it a computer monitor, a HDTV monitor or broadcast on the news. The video is a tall, door-shaped rectangle contained inside a horizontal rectangle. Just stupid. The production crew for the newscast often has to do stuff to the vertical video to make it at least a little more legible on a TV screen -usually by artificially zooming into it so the tall slit fills more horizontal space on the TV screen -all at a cost of making the video quality soft and blurry by blowing up those pixels.
I get annoyed by this nonsense because it gets back to some of the garbage many of us have to put up with in our day jobs designing signs. So many Americans do not have a proper grasp of simple concepts of geometry. And aspect ratio? What the heck is that!? I'm currently in "revision hell" over one project because the client can't understand just how many lines of routed aluminum lettering you cram into a 2 foot tall space before the lettering is all going to be tiny as f***. And there's flourishy ornate script involved in it too.
Another thing that makes vertical video painful: I've had conversations with some friends and acquaintances where they ask me something along the lines of, "Bob, you're a graphics guy, so can you help me make the videos from my phone look better on my TV screen?" I have to figure out the nicest way possible to tell them to hold the phone horizontally the next time they shoot a video without sounding like a smart@$$.
