Quote: Tony Northrup was producing 4K output until one day he studied how many people actually watched them in 4K ..... it was 3%, he returned to 1080P!
To most viewers, 4K of Tony might be just a bit too much narcissistic beauty to look at. And as long as he doens't invest a bit of his turnaround into rhetorical skills, it's also 4K of "uuuuhmm".
Let's face it, some YT guys do have to say something but the way they do it makes me want to talk in private with them, they appear to be shy because of the camera. For that I don't even need 1K.
Also, to add to the 8K or not question: In summary there's a lot more computing energy involved, right? Do we want more power stations because of high res cat (or rabbit) videos? It's not only to render the source footage, it's also to stream it. To me, who knows what film was resolving, it's every time a surprise to look at high res still pictures, but at home DVD still is the max I'm watching movies with.
My reason to go for high res sensors is that I like to watch details with time. 4K streams have so much details I will miss most of them and I don't believe higher resolution will add more to a good storybook or make a bad one better.
