Hi Jon,
Unfortunately those specs are a bit ambiguous. Fast download depends
on connection just as much as anything you do with the file. Also the
length of your file is a major contributon. For instance it's
unreasonable to expect a PAL quality video of 20 minutes length to fit
into 15-20meg, but you could easily get you 2-3 minutes of good
quality 720x576 video @ 25fps with Xvid.
Then on top of these issues you've got accessibility considerations.
Will your audience have the codec you chose. If you're going for
something widely accessible you will probably need to sacrifice
quality and put up with a larger size to ensure broader coverage
without needing additional software installed.
Also do you want to encode your video for free or are you willing to
pay for a program to encode it. Last one would be what platform you're
encoding on (though I'd guess windows).
Oh and also do you want the viewer to have the video play within your
page and do you want it to be easy to save it off to hard drive (for
the non-tech audience). I haven't checked the latest stats for flash
market penetration, but you can get decent quality at small sizes and
have it automatically play back within your page with wide
accessibility completely cross platform. However if they want to save
it off from flash then it's not a task most will be able to tackle.
Also use Sorenson Squeeze to compress for flash rather than flash's
inbuilt compression. The quality is greatly improved.
Sorry for being so vague, but it's not a question that can be given a
generic answer.
Cheers,
Alan.
