unfortunately this does not make differences in results either:

Then i can think only about that:
> ffmpeg -y -i in.mp4 -an -c:v libx264 -preset veryslow -b:v 2048k -refs 8
> -qcomp 0.7 -nr 40 -flags +loop -deblock 1:0 -pass 1 /dev/null
> ffmpeg -y -i in.mp4 -c:a aac -b:a 128k -c:v libx264 -preset veryslow -b:v
> 2048k -refs 8 -qcomp 0.7 -nr 40 -flags +loop -deblock 1:0 -pass 2 out.mp4
I'm realy stuck in here, I have tried any commands and any suggestions, but
I'm not even close to that quality (actually I need to be even better than
than one).
