Ah, ok.

So, since we're at "look at the preview release and say what you don't
like" anyway :-) here's another documentation feature request:

I understand that the processing is done in certain steps within
mpeg2enc. Would it be too hard to document:
- what are those steps (essentially, what happens in each one of them)
- what are the mpeg2enc options that are related to them
- what's the order of those steps

?

pleeease? :D

You'da man! I was looking for precisely the same thing: something to
boost the quality of the full frames, while keeping the delta frames
"good enough". But not so painfully pedantic as a full-blown hi-res
(which, BTW, is a bandwidth pig).

Thank you!

I'll do some tests.
