Seeing that, maybe try a different scaling algorithm, like bilinear? One thing that just came to mind: to check the impact of the color space conversion alone is like this: ffmpeg -i input -sws_flags bilinear -f null - To be honest, I have no clue if, the scaling algorithm has any effect on quality of the conversion, but at least it might be worth shot. On the other stuff below I am out of my depth. I am sure there are others, that know more on that. BTW, it helps a lot to provide the full output of the command, at least everything before the stats line.
