All you need for that setup is a VLabMotion. It compresses in motion JPEG with various compression rates. I bought one recently pretty cheaply on eBay but still haven't took the time to test it. These were suposed to be able to do video editing so that quality is not that bad. I don't remember if all the version of it had SVideo in but ver. 1.3 (the one I got) has SVideo in and out
ImageFX supports it directly I think. Pretty nice to have a top of the line classic system, though an NG Amiga would probably do the job better, but remember there are no drivers for capture cards AFAIK, nor is there video editing software for NG Amigas.
