Sorry Michael, I assumed too much. No you won't be putting the PAR in
"assemble" mode, rather your VTR. This is a feature of professional
decks as opposed to consumer grade, although some pro-sumer decks
allow you to do this.
A good example of a VTR which can do this is the EVO-9650 with which
you can do "insert" and "assemble" edits. Here is a quick primer on
the difference between the two.
Most home brand VTR's do "assemble" edits, which is why you get a
glitch when you start and stop recording. Newer decks have a feature
called "flying erase" heads which allow you to roll back into
previously recorded video and start recording with no picture
break-up. But this is still an "assemble" edit. Some even hold a
still image in memory from the last frame and allow you to continue
the action from there.
The difference basically between "assemble" and "insert" is that with
"insert" you have a continuous control track and or time-code and
that when you edit you're just inserting images in the video or audio
portion of the tape. This does not break control track or time-code
which are recorded on seperate channels. "Assemble" on the other hand
is recording video, audio, control track and time-code if you've got
it, all at the same time.
With frame by frame you need to do "insert" edits which means that
you have to have pre-stripped the tape with time-code. But because
the PAR plays back in real-time, you can put your VTR in assemble
mode, and even with a home deck that allows you to do audio only
recording, you can lay down the animation in real time and go back
and insert audio only, as the control track and or time code has
already been laid. However it gets more complicated the more precise
your start and stop time for audio needs to be.
