I made a movie somewhat like this with a friends Beretta and mine. I don't
have any fancy equipment, nor had the idea until after the movie was shot,

It is about 3mb. That's what you get with QT.
There are lots of movies on my main web site. The like is below. Most
movies are Real Media and are less then 1mb for a minute of video. All of
them are 15fps.
If anyone has movies they would like to have compressed, please contact me.
