 Graphic boards with P.A.L CCIR signal for video recording?

Subject: Graphic boards with P.A.L CCIR signal for video recording?

We intend to do animated computer graphics on video tapes.
We have bought a Sony VO 5850 P and a Video tape recorder
controller VES 12/88U from CFE to do single frame recording.

We are trying to find a computer graphics board with at
least 256 colors which delivers a video signal conforming to
the P.A.L. CCIR standard. This is needed for the Recorder as
input. Preferably the board should be for a mVAX or PC, but
other possiblities might also be fine.

Could anybody give me a hint, or tell me of your experiences
if you are using or doing something comparable.

                                Thank you in advance

Graphics in games are considerably different than the general issues
in graphics that you'll see discussed in Info-Graphics.  Rather than
general graphics interface, you are concerned with a special-purpose
application whose main requirement is speed.  While there are a number
of good references on the field of computer graphics (I recommend
Foley/VanDam's Fundamentals of Interactive Computer Graphics), as a
practicing games programmer for seven years, I have found that very
little of the techniques described in such a book are applicable in
games design.  The things you want to look for are high-speed BitBlt
type routines - games typically are most concerned with moving things
about on the screen quickly, not generating them from scratch each
frame.
