I've mentioned what I did in the past, starting with

built up the circuit in the AD724 datasheet. It's a surface-mount chip,
and circuit layout is a little important (a few MHz bandwidth video
signal), so I make a PCB. I've thought of making a slightly nicer one
(with VGA loop, though, etc). If there were enough interest I suppose I
could finish it off and send off for a limited run of PCBs.
Any chance for a PAL version?
The AD724 supports PAL encoding as well as NTSC, so it should be
possible. If I had SCART, though, I'd rather use that. It'd be better
quality than a PAL S-vid, since you could put out RGBHV directly, rather
than convert to Y/C and modulate on the color subcarrier.
