Hi Mark.
>If the delivery of MPEG-1 video is good enough for cable.. how much better
>quality do people really need for commercial work?
You're missing a key point. There's quality levels required for DELIVERY
(i.e., VHS is good enough for many people), and there's quality levels desired
for DEVELOPMENT (production). To put it in Amiga terms for example, it's a
good idea to work with 24 bit images even if the final delivery is HAM.
Television commercials are often shot on film with EXPENSIVE commercials edited
on D1 and all digital suites, EVEN THOUGH, most folks will watch it on some
cheesy television. The reason? The higher quality the process, the less lost
as it gets compressed, expanded, broadcast, filtered, etc, etc.
MPEG-1 and 2 provide the benefits of digital (perfect repeatability, random
access, etc.) without the huge bandwidth (storage and transmission)
requirements of original full fidelity digitized video.
OK?

Paul.
