Horizontal band member here. If I have to take a photo of a wardrobe, my whole self, a jumping giraffe or the Empire States Building, you can be sure as heck I'll hold the phone vertically. The only reason for me to take a horizontal photo of my fridge is when it fell on my foot.

Same thing goes vice versa: vertically filming a scenery, a dish, my mom's panties or a seesaw is plain dumb, unless there's something else that justifies the awful framing.

BUT when you make a video for the purpose of uploading it to sites like YouTube... You can't convince me vertical would make more sense. I understand that it's the same problem if it's a vertically aligned app (I could go on a 3 day rant about Instagram not allowing horizontal - or any - full screen on desktop), but decent portals do it properly. If you have a phone and you want to watch vertical stuff, problem solved. If you have a phone and want to watch horizontal stuff, just rotate your damn screen, it's a no-brainer. But when you have a monitor, you can't (always) just turn it 90 degrees and watch vertical stuff full screen.

Because of lazy uploaders AND lazy management/devs, there are countless of cases where a full screen video has actual content on less than 10% of the screen, because a horizontal video was uploaded to a vertical site, then you open it on a horizontal monitor and it plays like
