First you have to find out about your computer o/p got TTL RGB, or Linear RGB(1
volt pp).
If you got linear, then to transfer that into composite video,which you can
record on a vcr, you need a Encoder. Encoder can be NTSC, or PAL. Depend on what
format you want to record.
If you want good quality, then buy a industrial Video Encoder. Otherwise you
can design one by your self. There are lots of video encoder IC,s on the
market.
TTL RGB, only need to cut down to 1 volt level,before you feed into a video
encoder.
