I'm still a bit shocked at the "twice the quality and 1/5 the
price" results you're claiming - a 10x improvement in performance?
Not my experience... 2x to 3x perhaps at the outside, especially if
you're not using Sorenson 3 Pro 2-pass encoding. But yeah. H.264 is
a big improvement, if I can just get this color/gamma rendering
issue figured out!

I shouldn't get too carried away with my phrasing - "twice" simply
referred to the fact that I feel QT7/H264 is significantly better
than Sorenson - (that is, encoding a video that has little motion and
no transitions). The "1/5" refers to 1/5th the data needed. I don't
know if I would then multiply the 2 - to get factor of "10".
My guess is you set the "quality" level on the encode, not a bit-
rate target... "quality" settings are pretty arbitrary, in my
experience different codecs will produce greatly different visual
quality at the same "quality" setting so I find it mostly useless.
I really didn't touch the settings - other than size and H264.
Hopefully QT 7's implementation is corrected for WIndows in the
next week or so ;)
Corrected?
There are rumors out there - that during beta testing of WIndows
QT7 - QT7 was "hiccuping" badly - so the release was delayed. Of
course one never knows about rumors.
