Thanks for your help, Flick!
Believe it or not, the "fastest" setting works like a charm.
It seems as though, with "best" or other settings, Compressor is trying to
justify its second pass to the first, which, with very detailed black &
white footage, winds up with horrible loss. With "fastest," Compressor says,
OK, you know what you want, and the single pass looks great.
