the overlay of computer graphics with live or recorded video (best if it's very stable, such as
from a live camera or laser disk player).
The Amiga is an excellent way to go; it was designed from the beginning to be video compatable,
and several inexpensive genlocks ($200 US or less) will give better results that adapters
costing 2 or 3 times as much for the IBM or Mac. Anything from an old Amiga 500 through the
A1200 or A4000 will work very well. Also, you will find a good variety of paint and titling
