[sci.electronics] JVC single-frame recorder

milo@ndmath.UUCP (Greg Corson) (08/03/87)

In "Computer Graphics World" recently they mentioned another recorder that
might be able to record a frame at a time for animation.  The recorder
was the JVC BR-9000U.  Supposedly designed for security applications they
seemed to think it was stable enough to do one-shot recording of computer
animation.  If anyone has had any experience with this machine please let
me know.  I would be very interested in hearing how well it works.

They also mentioned the SONY EVC8 8mm editing system as a possibility for
single frame recording.  It's a double deck 8mm editing system.

I also recently got some info (very little) on a machine by Panasomic that
is supposed to be able to record a frame at a time.  It cost around $2700
I will post the model number when I can find it.

Most of the recorders with built-in single frame recording seem to be
designed for security applications.

What is meant here by single frame recording? It would seem to me that the only
type of machine that could record a single frame would do it while the tape
is stopped.

I'm trying to put together an inexpensive animation system (I don't want to
waste my money when S-VHS editing decks will be out next year), and have
come to realize that I don't need single-frame recording. What I need is
frame-accurate editing (so what if you record n>1 frames; you just back up
to the end of the first one and record the next image).

Something like the Panasonic AG-1950 may be quite adequate (if one can 
tap into that mysterious TTL control interface that they use with their
editing controller).

The May 15/87 issue of _Sound & Video Contractor_ has an article
on time-lapse VTR's, written by Neil Heller, a video security
consultant with Gyyr Products, Anaheim CA. Gyyr manufactures
(modifies?) VHS compatible time-lapse VTR's. The article explains
the problems associated with noise-free single frame recording and
the approach used by Gyyr to overcome these problems. I can't claim
to fully understand the process, and the article is too lengthy to
include in a news item (especially at the speed I type). However,
there it is, and here is Gyyr's address for anyone interested:
