Also, what about thred count? I put threads=18 in the advanced options in handbrake, as i have 12c/24t 5900x, and opening 36 threads is a lot, as the quality loss begins to become noticable at that point. For my 4k stuff, i essentially set the same settings as film tune manually, but i cant remember what it was. I also want to know if i should leave tune at none, as there is no film tune. Im asking if theres is maybe a 1-2% improvment in efficency, at like half the speed, and is therefore not worth it, that kind of question. With x264 veryslow i can encode faster than realtime pretty much, 25-30fps give or take, and thats with limiting thread count too. In terms of preset, the general wisfom is to go as slow as one can bare, but im wondering what the difference is between slow and slower mainly, im not too concerned about the others. Im not as familiar with x265 as i am with x264, and i have a couple of questions. The harder to compress stuff, where 7mbits can be considered a "low" bitrate, will benefit from x265s efficency and wont be stupid artifacty. Im think of using 7mbits, which im aware is a bit high for x265, but i dont mind bloating the easilt compressed stuff a bit, at least i know the quality will be practically lossless.
Im thinking of using 10bit too, and with 2 pass abr instead of crf as with my current settings, the file sizes can vary so wildy, and some files actually get bigger. I was thinking of using staxrip instead as its what i use for my 4k blurays, but im still a little confused with it. In handbrake with x264 i use crf 18, very slow, film tune, high profile, level 4.1. Im thinking of changing my bluray encodes from x264 in handbrake to x265 to squeeze out a little more space.
