Spent the day learning how to use Davinci Resolve 18. It’s a super-cool (though complex) software! If you’re interested in video editing and have good PC, then try it out. It’s completely free, and it’s actually used to edit Hollywood films.
I haven’t had any trouble with that - though to be honest, I don’t know if it was using my GPU or just my ridiculously powerful CPU. I’m pretty sure the GPU works, because I was rendering some pretty complex 3D effects super quickly. Either way, it hasn’t been a problem.
