Thank You for interesting information, xooyoozoo. And for screenshots.
Can I ask You to re-do the same test but on real scenario conditions? Like 1-2 Mbits 720p, 3-4 Mbits 1080p and 500-600 kbps for SD, 480-576p.
It's unlikely that someone encodes 1920x1080 at 535 kbps here.
P.S. The original.png will be good too.
