Renee, I did some experimenting earlier today with a two-minute file (DV
AVI) using the Procoder Express plug-in for Premiere, my tool of choice
for
wmv encoding. The first export, at a combined video/audio 272 kbps, 15
fps,
320X240 2-pass constrained VBR came out at 3.9 MB, or roughly 2 MB/min.
The second, at 128 kbps, 15 fps, 320X240, 1-pass CBR came out at 1.7 MB,
or
just less than 1 MB/minute, which I think is your target. If you want to
look at either of them they're at www.contentshop.tv/procoder.htm -
they
are the last two files in the list (Vacation). I identified the smaller
file as 108 kbps but it's in fact 128, as you'll see in the player.
They are impressive, but to be fair let's keep in mind that most of the
material was still photos. The test of a codec is how it handles motion
but that's not to say that Procoder did a bad job..it was excellent
because the file sizes were the most impressive point about it.
The motion scenes were also quite good!
If you're willing to halve your frame rate, compose your motion scenes
carefully and keep your bit rate down you can do some incredible things
with a couple of megs.
Here is an example of a "typical" four minute music video at the
traditional 29.97 (NTSC) frame rate, with the bits upped to 548.
A lot larger but still within the usual 20 megabyte allowance that most
broadband ISP's a lot to their customers for "personal online storage"
which means you could upload a video like this to your personal "web
space".
I don't have Procoder so I simply took the DV-AVI file and used the free
Windows Media Encoder to convert it.
Cheers,
