Yes. It supports yuv(a)444p10, is that better quality or what?

When I match profile, pixel format and bitrate very small win goes to
aw encoder.
I see no reason to keep it even in that case as aw one does not
support any bitrate
control besides its profiles. So using -qscale gives always same output.
