Why are so many YouTube videos portrait rather than landscape now? - Blåhaj Lemmy

The sheer number of videos taken “the wrong way round” (for my computer’s monitor) is mind-boggling. I get that some people watch videos on their phones, but is it really that many?

I would assume because most videos are taken from mobile now. Camera quality in phones is crazy good now.
I mean, like I suspect for most people, my phone is my camera too, but it's perfectly capable of taking landscape videos.
I think this is going to be a generational divide. Most of my millennial friends will insist on landscape while zoomers tend to default to portrait.
My Moto G Stylus even does landscape videos with the phone held vertical. Moto gets me.
Right. I only take vertical if I'm showing a tree or a plant but for a scene or most other pics it's horizontal.
