Let's start with your last question. One hour of mini-DV source material
requires about 13 GB of disk space. To turn that into a DVD you
compress/encode it as an MPEG-2 file. In many authoring environments
(MyDVD, TMPGEnc, DVDit, Encore) you select the bit rate(s) used to make the
file, which trade off size and quality. For an hour's worth of material you
can get good quality with a high bit rate and still fit the material on a
DVD-R.
To the question of what file format provides the best quality at the
smallest size the first issue is how it will be shown. If it's going onto a
TV via a DVD disk it's as above. If it's going on a CD or hard drive for
viewing on a PC you're probably best to select Windows Media Video (wmv) at
no less than 500 kbps. How much higher a bit rate you use to reach the
quality you want is a matter of experimentation, and will vary with the
content involved. Lot's of action and dissolves between clips requires a
higher bit rate to look good. Talking heads and quiet scenes can work with
fewer bits per frame. I hope that helps.
Finally, Windows Movie Maker uses the term "save" to mean "export". In
Premiere, saving keeps all the bits together until you save again, while
exporting involves selecting a destination (back to the camera, or to VHS
tape) or a file format. What file format depends on what encoders you have
installed.

What I don't understand is that if you do the same project in
Windows Movie Maker just without as much precision, and save it
through Windows Movie Maker, the quality is pretty good - only
slightly lost- and the size is incredibly small. How come that is?
Isn't there a setting like that for Premiere Pro 1.5? I've tried
what WMM says- WMV file, Bit rate 896 kbps, 30 fps but when I save
in Premiere it always comes out larger and sometimes not as good of
quality. Understand? Sorry if I'm confusing you.
So what I'm really asking is what do I save the file as in order to
maintain the best quality but have the smallest file? How does
everyone put it on dvds when their movie is like 1 hour long but
when exported its like 11 gigs?
