The entire point of constant-quality VBR mode is to reduce bitrate
spent in complex scenes... which you have proceeded to disable by
setting qcomp to 1.

I am not going to bother helping people who explicitly override
intelligent encoder decisions with misinformed ones of their own and
then complain when they get suboptimal results.
