Thanks for your reply! I use for 4k encoding this settings with
Preset Slow and as i know the red ones affect to speed:

--rd 4 --limit-refs 3 --bframes 8 --rc-lookahead 72 --me star --max-merge 4 --ref 4 --subme 5 --weightb --b-intra --tu-intra-depth 3 --tu-inter-depth 3 --no-cutree --no-sao --no-open-gop --no-strong-intra-smoothing --ipratio 1.35 --pbratio 1.25 --deblock -3:-3 --qcomp 0.65 --aq-mode 2 --aq-strength 0.8 --psy-rd 2 --psy-rdoq 2

So, maybe i should use something like --no-rect for compensate slowdown and use --hme umh, umh, star? Or maybe decrease some other settings. I mean, it will more useful to improve perf @ quality?
I ask cuz my speed for now is 1-1.1 fps and i don't wanna go much lower than 1.0 fps
I'll do some tests with PSNR and SSIM tomorrow.
