My prediction of 2/3 smaller was based on doing the one episode, which
happened to compress well. I was probably too optimistic. ;-)
You know, it probably shouldn't be surprising when we consider that
50% or more consists of old archival footage - raw, unprocessed, noisy
material, and lots of it taken from analog TV. In fact, I've seen
docs get larger not smaller for this reason. I cranked the xvids
through HB at CRF 23 and got an average of 534 MB per ep. If I'd gone
for CRF 24, the average might have slipped under 500. And that was for
resolution of 640x480. You're probably going for the max (PAL)
resolution, closer vto 720x576. Therefore, if I had the original
DVD-9s, I'd go for the better resolution, use a setting of CRF 24, and
accept what resulted with the filesize.
BTW I misspokie yesterday. I said that the original poster did the
audio at 81Kbps. I must have had a brain fart. When I looked again it
was actually 192K stereo.
