I wasn't after a frame grabber (convert video to rasters) but the opposite
(rasters to video), which seem to be what most of the commercial products
are for.

The general consensus seems to be that the Sun's are not like Amigas and
SGI's and you can't just buy a genlock to generate sync for a video recorder.
You need to buy a frame buffer that has NTSC/PAL output or a scan converter.
Surprisingly there doesn't even seem to be any commercial SBus products
available to do this sort of thing (I hope I'm wrong).
I thought it was a common and fairly logical sort of thing to want to do with
a workstation, be able to produce video taped animations for demos, conferences
etc, but obviously not. I have asked my local Sun graphics expert, who has
asked another expert, and he will give me a 'definitive' answer. If it looks
reasonable I will pass it on. I'll also try and get some info on the SBus
frame buffers and see which ones look reasonable

Anyway thanks for info suggestions and anecdotes from :-

pratt@coraki.Stanford.EDU (suggested that HDTV recorder may work) (suggested using movietool)
