From my rather exhaustive experiments, I have found that you can get a very
wide range of sizes for your output file.  I've gotten compression ranges
between 20:1 and 500:1 with different settings for the same animation.
Quality is in direct proportion to the compression ratio.

I recommend using the Berkley MPEG encoder.  It takes a bit of work to use,
but gives you the most control over the output.
