Help with understanding video encoding hevc implications and how to do it. I'm thinking for a while now to encode my videos collection to hevc.
I did a little test and used handbrake(cpu) and StaxRip(gpu).
and the results were astonishing, using StaxRip- gpu was around 10 times faster than handbrake - cpu.

My gpu intel i7 7700k
Gpu nvdia 1070
Ram 16gb

So I read here about losing some quality if I'm using nvenc, but the performance were outstanding.
What I'm trying to ask is if there is some way to encode it without losing any quality.

Most of the videos are hd or fhd.
