You are talking about video toaster. Is there a way to use a video toaster with an A1200 that I am not aware of, or does this work in an A4000 too? This would definitely be an A4000 winner for me!
A Video Toaster could probably be used with the A1200 bus boards that have a video slot.  The only snag is that another board needs to clip over the Lisa chip in order to take the video native video signals to the bus board.
Jens says that another version is planned for the A4000.
