First of all, please think of the dimensions of the T.V. screen with respect
to a theater. You do need a lot higher definition for those sizes but HDTV
resolution should be sufficient to produce picture leaving the audience
less desireous of 35mm films.

Another factor: the print film's resolution is fixed; better lens may
improve the picture but there isn't much else you can do to it.
You can take that same HDTV resolution and apply well-known image
processing techniques to increase resolution (contrast enhancement for
instance), to apply anti-aliasing and a host of other
filters to come damn close to print film. So lets not despair.

And then those of us who are in rural areas (or can't get decent reception
for whatever reason) lose all the broadcast stations.  For instance, if I
disconnect my cable and use an antenna (on the roof) I get 2.5 channels (2
half-decent, one barely watchable).  With cable I get all the broadcast
channels I could want and then some (ie, 3 FOX affiliates, etc...).  And I
live in f'king New Jersey! What do you do if you live in Montana or
someplace?  I'd pay a buck or two extra a month to keep these channels.
I'd rather go on the way I'm paying now, of course...

The most recent issue of PC Mag has a short (half page) write up
(Sept. 29, pg. 42) on the Video Blaster.. 

To summerize:  The board has three composite video connectors, 
switchable via software. It does not support S-video input. Includes
a mixer and stereo audio input and ouput jacks. No treble, bass, or
balance control. Allows 2.1 million collors.  Image quality is good,
though close inspection reveals a few flaws, suce as distortion around 
the borders of moving images. Rudimentary DOS controller software as 
well as more sophisticated Windows utilities that let you scale the
video window to any size. Can freeze video image (capture) in .BMP,
.GIF, .PCX, TIFF, .TGA, or IBM MMotion files in color depths from
8 to 32 bits.  Has a Windows Media Control Interface driver, which means
any Windows multimedia package that can send MCI commands can control
the Video Blaster.  Comes bundled with Mathematica's Tempra Show and
Crative Labs' MMPlay. List Price: $495. Requires: 2MB RAM, full length 
16-bit slot, VGA adapter with feature connector, DOS 3.0 or later,
Windows 3.0 or later.  Creative Labs Inc., 1901 McCarthy Blvd., Milpitas,
CA 95035; 800-998-5227, 408-428-6600.

product, and appologize to PC Mag if I am infringing in any way

OK. Seriously. It's a copy protection system for VHS tapes wich takes advantage
of the slow AGC response of VHS VCRs by putting some very high white level
signals in the vertical retrace. There have been many versions of Macrovision
which have tried to keep this from effecting any TVs, but, so far, they don't
seem to have suceeded. I have no idea what the name "Macrovision" means in this

There is a FCC ruling (PRB-1) that states that communities may not restrict
the building of antennas by zoning rules, local ordinances, etc.  This
ruling does *not* apply to deed covenants, which are deemed voluntary 
restrictions.  If you sign the deed, you agree to the antenna, skylight,
flagpole, toolshed, etc. restrictions.

I just read an article in "Video Systems" Sept 92 pp4 titled 
"Patent impending".  This short article was about how Montage has
patented the use of the storyboard/time line approach used in non-linear 
editors.  Did anyone else read this?  Do you also think this is nuts that
a company could actually patent/copyright the way on-disk video data is
displayed on a video screen?  This to me seems like a variation on 
'look and feel', a concept that aids all involved and should not result in
royalties to some lawyer fat company (it aids user, developers, marketers,
etc).  Another thing, as implied by the article and MANY articles in the
Communciations of the ACM, patenting software... what the !@#$!@#$.  
All this accomplishes is hurt the little guy.  Big companies go for
something which they aren't sure that really can protect them, but hey
they have the money.  The little companies end up at the short
end of the stick since there's no way they could ever attempt to even
fight the larger company.  Hence the big company gets to do what it
wants

Is there a non-biased informed individual out there that could shed 
some light on this issue?

If animation is your goal maybe you should look at the Sony EVO-9650.  It has
VISCA like the CVD-1000, single frame recording, video/PCM/time code insert,
and digital special effects. I believe the time code is 8mm time code and not

Yes, check out the Sony 9700, dual deck Hi8 editor. It goes for just under
$5000, and has a slew of nice features, including time code and insert
capabilities.

>Is there such a thing as an editor that would talk to Hi8 as master

Yes, check out the Video Toolkit from Abbate (sp?) software. It is a Mac
based program that can perform interformat editing, even between consumer
and professional gear. As far as I know, however, it is limited in its
insert capabilities.

Funny, I would describe the HQ circuitry as a silly consumer function.  It
makes the picture "better" by filtering and removing information from the
source.  The result may look better to some, but it's basically an optical
illusion.  If you care anything about generation loss, you want your copy
to be as close to the original as possible.  Therefore, you DON'T want HQ
processing while copying.  The picture from my camcorder doesn't look any
better to me with the HQ circuits active, so I leave the edit switch ON at
all times.  So I guess we have two opposing viewpoints here.

At any rate, in answer to the original poster, whether you agree with me or
Mike, the edit switch is only supposed to have an effect when playing back.
The position of the switch on the recording device should make no difference.

        Can the Video Toaster really be full broadcast quality?

        Conventional wisdom dictates that it is impossible for a device as
        inexpensive as NewTek's Video Toaster to generate a true broadcast
        quality signal.  However, new technology breakthroughs incorporated
        into the custom chips invented by NewTek are changing the price/
        performance rules of the entire video industry.  The following
        reports show that the Video Toaster fully meets the most stringent
        specifications for broadcast video (both RS-170A and FCC).

    It goes on to list all the specifications and show that there are
no violated upper or lower limits for either the FCC or RS-170A specs.
The tests were performed at KSAS/Fox Television.

    As for contact info, the Video Toaster Answer Line is 800-368-5441.

   The Video Toaster is a bit big for the A3000's small form factor, and makes
for a rather tight fit.
   The uppermost BNC, Input 1, will not go through the slot in the back of your
machine, so you'll either have to cut room on your A3000 (thus voiding any
warranty you may have), or remove the BNC and resolder it onto the bottom
(after Preview Out).
   Initially, the Toaster had a problem running with the A3000's ECS Denise
chip, but Video Toaster's 2.0 software removed that compatibility problem.
   The A4000 appears to have a small form factor as well, so I suspect that it
may be a tight fit in there as well.
   As an option, a product called "The Toaster Cozzy" ($799) can be bought.  It
is an external case that will house and power your Video Toaster for your
Amiga.  Makes for easier access to your BNCs.

If this is a FAQ, please direct me to it.

I am involved in lighting simulation of architectural spaces using raytracing and radiosity.  Up to now I have been using film recorders to produce a "hard" copy of these images to make them easier to view for those without a computer.  I am interested in using videotape as an alternative media but I need some basic information about what is involved.

I will be using a Indigo(R4k) Elan as my primary platform.  Because my images are 24-bit I would like to use hardware which has comparable accuracy.  I have heard that I will need a "frame grabber" but I don't know very much about what it does except "grabbing a frame" from the screen.  Could someone point me to a source of products available and/or give me a brief description of what I should look for.

Also, what kind of specs and features do I need in a VCR?
