This seems feasible, |but is it really? I realize it means triggering an edit pre-roll - the |triggering and synchronization of that with the Amiga is what throws me. Being a person from Sony I cannot comment on the JVC product directly. Most likely this is a consumer grade deck without any sort of serial interface. Without this it is rather difficult to achieve perfect results. The edit pre-roll feature probably means that the deck will automatically backspace a specified amount, begin playing, and send a release-Pause command to another deck at the specified point. This is not what you need. To do seamless edits you need a deck which can start recording on a specified point. Most consumer decks are incapable of this. Of course if you just want to dump an already made ANIM to tape all you need to do is manually find the insert point. Set record-pause and have the Amiga send a release record to the deck. Just how you do this is beyond my knowledge. My guess is that the JVC wants some sort of TTL signal at the remote port and could easily be done witha line on the parallel and serial port. So if you had such a cable, AREXX, and an AREXX compatible ANIM player all this is possible. To get the best results you would have to time the release time on the VCR's remote pause terminal. None of this sounds elegant, but it is doable. Of course if you had a Sony VCR with LANC (all 8mm and some VHS) and the Sony Vbox, this would be made a lot easier. The Vbox is a serially driven interface to conect Sony LANC (and Control-S) products to a computer. If you need info on this product contact Sony CPP in San Jose. Of course now I'm turning this into a commercial and should stop here. Sorry I couldn't be of more help, but you should contact JVC about a better solution. |John T.
