[comp.sys.sgi] Help me make a video!

I have been working on a SGI 4D/60 system producing colored animation of
solutions to time dependent partial differential equations solved on a
Cray X/MP we have ethernetted to the graphics workstation.  I really want
to use the RGB outputs of the color monitor to make movies.  I have experience
with a straight color film recorder, where the RGB from a device are used
directly to phototgraph the RGB components of the film, and the frame is
advanced in the camera via a trigger from the video monitor.  Film is really
quite nice, but it would be nicer if I could do essentially the same thing
(frame by frame triggered recording) onto VHS format video tape.  Thus my
question to you out there is if any of you have facilities for doing this
please tell me what hardware you use, and if you can a little about the
spatial and color resolution of your final products.  I am really not
interested in an entire video editing system, and if new video camera
technologies (with triggers) do exist that give high resolution I would
also be interested.

                                      Thanks a heap,

                                      Michael Mascagni

I've always been under the impression that the ~$50K figure should really
be around ~$3K, and that it isn't due purely to marketing considerations.

For people with small pocketbooks that are interested in previewing
animation quickly (that rules out film...), I'd suggest a cheap
black-and-white single frame VCR.  I used one in an animation class
here at UCLA 4 years ago, and it was perfect.  For the final project,
beg some place with real equipment to let you use it at night...
direct to video, or 35mm and then transfer to video.
