What is the application you are trying to meet?  I am not familiar with
the AG-1970, but I would suspect that it is an upgrade to the AG-1960
and if so I don't think I would use it.  It probably won't stand up to
the abuse as a time lapse recorder.

If the image quality only needs to be fair, I would suggest looking at
the industrial S-VHS decks (the ones used in security systems).  I used
to use a Panasonic AG-6750 but better ones have since hit the market.
I think Hitachi even has one that does time lapse audio recording.  Look
around, prices start around $2000US.  The advantage to these decks is
that you probably won't need the timer or the edit controller and there
is no need to pre-black tapes with time code.

If you need good to excellent image quality move up to high end S-VHS
decks such as the Panasonic AG-7750 or the high end HI-8, prices around
$5000US.  Of course with these decks you will need an external edit
controller to control when and how much to record (and tapes will have
to be pre-blacked with time code).

Another approach is to get a good quality consumer grade camcorder with
a time lapse switch.  What these do is record for about 1 second at each
interval.  You will need to have some way of editing this down to one
frame (or field) per record segment.

If you do go with the low end products you will also probably want to 
invest in a time base corrector.  Like anything else in life the more
you pay for it, the better it is likely to be.  Also look for an
expert in the field for guidance (I am no expert).

Since you are interested in the Toaster, what about the SunRize AD516 or
AD1012?  The manufacturer claims these boards digitize 16 or 12 bit sound
on four or eight channels (respectively) direct to disk, let you mix 'em
back down to two or one channel (respectively) and output 'em again, with
SMPTE synchronization.

So how about reading the audio tracks of your raw footage with SMPTE into
a SunRize board, mixing in other stuff, and then outputting them to the
tape with SMPTED sync as part of, or after, the video edit?

Can anyone enlighten me to a device that Abekas has to allow a D-1 (or 2 or
whatever) tape deck to be connected up to a computer via a ethernet 
connection?  I'd like to get a list of people that are using such a
system and what they think.  I just found out about the existence of
this do hicky the other day, so I just want to find out what it is 
all about.  Are there any other products/companies that have similar
devices (Sony?).  

Basically, I posted a message about wanting to doing video capture to 
harddisk.  However, there is NOTHING out ther today that can really
do this in real time (one of the problems has to do with bandwidth
of even the fastest drives being not even close).  I need high
quality capture.  Current compression boards (using things like JPEG)
will not be able to produce a CCIR-601 image and still be within the
bandwidth of standard drives (simple math will tell you that).

As I said if anyone can give some advice I'd appreciate it.  I might
even appreciate some marketing person telling me different about 
video capture using JPEG boards...

I can't resist mentioning a similar market that I dreamed up years ago.

When eating in a cafe with a loud jukebox, I suspected that there were a
number of people (myself definitely included) who would gladly pay $.25
for three minutes of silence.  It shouldn't be much of a technical challenge
to produce a record (nowadays CD) with no audio output.  I was daunted by
the problem of convincing jukebox owners to add it as a selection.

  I believe this is a gross misinterpretation of what Vidiot was saying.
There are numerous criteria one uses when evaluating consumer electronics
of any kind.  The criteria each individual uses should correspond to their
own wants and needs.  If someone places great value on their clock surviving 
power outages, it is not unreasonable to think that they would look for
this feature at the time of purchase.  In that context, the decision to
purchase a vcr without this feature was a "poor" one because it necessitates
the purchase of an add-on unit to achieve something that could have been
included in the original (without settling for poorer picture quality or
inferior recording modes).  As Vidiot explained, his intent was to inform
people now looking to purchase a vcr of a possible additional criteria to
consider so that they may save additional expense at a later date (in the
form of an add-on VCR+ unit).  His post did not warrant your flame.

I believe that if you only record and play back in sp mode, it won't
make a difference, however if you are recording and/or playing LP or SLP
(EP) it will make a difference. in the quality of the recording.

Martin, i wouldn't worry to much about having a loudness button. As near
as i can tell no stereo equipment manufacturer has made a true loudness 
contour mode for years. Sure they have button labeled loudness but all
it is bass boost that has the added feature of possibly blowing out woofer
cones if used at higher volume. So if the equipment has a bass control 
just turn it up at lower volume levels and down at high instead of pushing 
a switch.

To tell if a tape is macrovision encoded, play it in a vcr and fiddle
with the vertical hold on the tv. The bar at the top/bottom of the
picture will have bright pulsing rectangles instead of the normally
dark bar. The basic principle behind the macrovision eliminator boxes
is to recreate or blankout the rectangles from that bar.

The only time i've noticed bent vertical bars was after doing some

Does anyone know what the cause of a periodic crackling on the Nicam 
sound output of my Mitsubushi HS-B52 video could be. The crackling is
not present on the mono FM soundtrack, and is not accompanied by any
disturbance to the picture. Other people I know receiving Nicam from
the same transmiter (Sudbury, Suffolk) speak of a crystal clear signal.

The crackling sounds the same as you would expect from electrical
interference, but I have heard it even when I have ensured all other 
electrical appliances in the house are turned off (including central
heating boiler !)

The interference is also present  when listening via headphones connected
directly to the video recorder.


Any suggestions gratefully received.

Forget magnetic, but optical storage is definitely an option!
If what I've heard is correct, the CD standard is being re-defined - future
CDs complying with the new standard (which I'm not sure when it'll be finalized)are supposed to have a lifetime of 1,000 years...
And CDs are durable enough if you handle them carefully and don't get them

NNTP-Posting-Host: hela.ins.cwru.edu


Last night I purchased the Sony TR71 after a long and hard debate over the 
TR71 and the FX510 Handycam.  But I'm still fighting over the decision.  
(Why did Sony have to make such similiar cameras?!?!?  It would have been
easier if there was only one choice!)  The main differences come down to:
 
Size - TR71 is about 4X4X6 inches     FX510 is about 4X4X10 inches
Weight - 1.4lbs 			1.9lbs
Lux	 2 lux				1 lux
Feature  Mosaic graphic digitization	Superimposed graphics
 
I think the final decision was based more on size.  The TR71 is just so
small and compact.  The FX510 did not really feel heavier, and was just
as comfortable to hold, but may be slightly more difficult to carry around.
I was also torn between the two graphic features.  I really like the 
superimposed graphics.  The mosaic feature is ok, nothing special.  Probably
would be good in transistions.  My question would be does anyone really
like the superimpose feature, and use it quite often?  Both of these cameras
are the same price.  Does anyone have a recommendation for either?  Would
or is the reliability factor in favor of either?  How about latest technology?
Would any of you choose one over the other, and why?  Any replies greatly
appreciated (I have two weeks to take back the TR71).  Thanx!!!

ps - the main uses of the camera would be sports (indoor basketball and 
outdoor football), skiing, beach/ocean scenes, and the usual indoor

This just means that the video has been re-released in a consumer package
that is nearly twice as long as the video cassette itself.  This package
was used in the initial release of "Rattle and Hum" to music stores three
years ago.  The "long box" (like the current CD packaging) is designed to
allow record stores to display the video in an existing record bin.

The JVC HR-S7000U and HR-S8000U are the best S-VHS VCRs I've ever seen.  
It's a real shame they were discontinued three years ago.  Anybody have a 
used one (either model, in excellent condition) that they want to sell?

I've had my HR-S7000U for 4 years now and I want to get a second VCR.
Nothing on the market has the same features - for example:

- Program the VCR while it's recording, even while it's timer recording. 

- Both on-screen and front display programming.  Programming via the front
  panel or via the remote.

- Programming when the VCR is off (sounds weird but the JVCs can do it)

- Automatic index marking when record is invoked.  

- Manual marking of indexes in either record or play mode.  Manual erasure
  of index marks

- Address marking (up to 9999 addresses per tape).

- Manual marking and erasure of addresses.

- Manual or automatic control of audio levels.

- Manual tracking control (no automatic tracking for me thanks especially
  after hearing about all the problems with HiFi dropouts).

- Switched electrical outlet on the back (to control monitor).
