I'm not Leonardo but Leo does 720p and 1080p because of his PC and he does his best and we all appreciate it. I wasn't judging you, i'm just saying that if was already upscaled in amazing quality, then try other music videos, try to make them more detailed, my PC is garbage honestly and can't do a piece of what some people shares here, but if you can do 4K videos, then try to lower the resolution and focus in the details as much as possible, i guess is lower time of rendering with HD & Full HD compared to 4K. And again do not get me wrong, i think you can improve a lot if you try other configs to your upscales and wouldn't be really neccesary to make them in 4K and sorry if i sounded rude in my words, my english isn't good, sorry.
