Timothy,
Kevin is right, you don't need a frame buffer to create targa images if you
want to take them to someone to transfer to tape, but what you do need is gobs
of hard disk space. .TGA files can often run a meg and a half or more for each
image (depends on the resolution, colors, etc) and at 30 frames a second for
video your talking about a lot of storage space! Assuming an image of 1 meg
for each file, a thirty second animation will require 1 meg X 30 frames per
second X 30 seconds…or 900 megs of disk space!
Don't despair though, a rewritable optical drive with a 1 gigabyte capacity is
not too expensive.. at least comparatively speaking.
