Pre-roll simply put means that a VCR remembers where it wants to insert, backs up the tape, plays until the insert point, and begins recording at the insert point. This requires two very important elements: time-code and flying erase heads. >Flying erase heads are becoming a standard feature on most decks (all 8mm VCRs have them), but time-code is currently not available in any VCR. This will change in the future (look for them RSN). Ok, I just bought myself a JVC HR-D960U. This is a very nice (my opinion) deck with jog/shuttle, flying erase heads, some sort of time stuff (we are bouncing off the outer limits of my comprehension here), and edit pre-roll. It has the most beautiful and solid freeze frame I have seen to date, and the jog and shuttle controls make it very easy to home in on an exact frame. Now: How do I use this to do single frame recording? Do I need something called an edit controller? I have been staring at the instructions for setting an insert point and starting a dub there using a second deck and the REMOTE PAUSE terminal, but I don't really understand what that means. I would like to be able to position the tape to a frame, poise my Amiga to output a composite signal containing an ANIM (via DCTV), and through some magic have that signal begin recording at that point. 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. My gut feeling is that what I want to do is achievable, but whether is it easy or requires some extra hardware or horrible kludge, I don't know. Help? -- John T.
