Gary,

My personal experience with wmv is that a range of 10 megaBytes per minute
at the high end and maybe 2 or 3 megabytes per minute at the low end
represents the range of quality I would consider acceptable for web and
casual TV viewing. This would require, therefore, file sizes in the 120
megabyte to 24 megabyte range for your 12 minute movie. I have made files
one tenth the size to carry full length movies on my Pocket PC, and thus
have fit 2 hr long movies into 100 megabyte files as well using wmv, but the
quality is barely acceptable.

The issue I think is mostly what you consider "good quality" since Windows
Media Encoder can make your 12 minute movie into a 10 or 12 megabyte file if
you are willing to sacrifice high speed motion, full bandwidth stereo sound,
etc. I send email movies to family using this approach and people are
delighted with the results, but I also demand over 3 Megabytes per SECOND
(approx 200 megabytes per minute) for the HDV hi def video I edit and
watch, and everything else looks like "low quality"!

My point is.........either you choose the file size you accept and let
Windows make the best movie it can to fit it, or choose the least level of
quality you will accept and let the file size be what it may.

None of the compressors have any better efficiency / quality per megabyte
compared to wmv format at the lower end of the performance range, and even
at the higher end the wmvHD format is pretty amazing, all considered.
QuickTime with a Mac can do similar very good mpeg4 / H.264 movies also if
you have such hardware and software.
