I wanted to test how the quality of lavc's encodes would differ using 
the short answer is bad (they look much worse than with lavc's rc code), 
but what
is even more evident is that activating qprd the bitrate of the second 
pass shot to
the stars: after 60 seconds it was already 8.1 Mb/s.

BTW, what does qprd do (the explanation in mplayer's man page isn't 
exactly understandable).
How much does it generally improve visual quality?
