For what it's worth, though the MPEG encoder specs support full, 16-bit

I didn't know and I am mildly surprised (16bit video is very uncommon).
Otoh, "MPEG encoder spec" is not very precise...
monochrome video, all of the modern DVDs that I've encountered
use YCbCr 4:2:0 for black-&-white movies.
Because that is what the DVD specification requires.
Ah! Well, that explains it. Thanks Carl Eugen. I haven't spent the
$5-thousand for the DVD spec.
This is part of the publicly known, non-secret part of the specification.
By the way, of course, I made a silly mistake. I should have written
"full, 24-bit monochrome".
I am curious: Which MPEG specification defines 24-bit monochrome
encoding?
Oh, gosh, I ran across that long, long ago. Since it's not used for
DVDs, I just noted it but didn't document it. I'll be on the lookout for
it and get back to you, but don't hold your breath. :-)
Regards,
Mark.
