I'm posting this query for a colleague who cannot access the net
directly.  He is apparently unhappy with the audio recording quality
on his Panasonic AG-460 2-chip SVHS camcorder.  He is trying to record
piano performances and is having problems with flutter.  He borrowed
another one from his dealer and had the same problem.  I loaned him
my Sony V5000 and he did not have the problem.  Here is his query:

# Is there any poop on your network about Panasonic 460 camcorders and
# performance with Hi-Fi audio?  Panasonic is supposed to announce
# a new SVHS camcorder with 3 chips this week at some show in New Orleans,
# but it may be SVHS-C.  The small drum could be a problem since flutter
# is a real problem in trying to record piano.  Sure wish there was
# an SVHS format with digital audio -- flutter problems disappear I
# would think under a digital sampling scheme.

Any comments or solutions?  Thanks!

Hi Joe, 

I haven't done it before, but from what I understand - you're doing frame
by frame editing (i.e. like computer animation)?  If so, you remix your
sound later, I think, using a professional audio deck.

IM putting the final touchs on my video toaster system.  I have been shopping
around for a a/b editing system and a single frame recorder.
Anyone have any thing to say about this system?

Sony SVO 9600
Sony SVP 9000
Sony SVBK-140
RM450    
S-VHS Pro Editing System.

estimated price $7500 

KNow i just talk to the and he said that the system is 100% compatable with
the toaster and that one of the decks does Single Frame Recording for animations?? Anyone know anything about these systems?  Do they come with TBCs?
Does it single frame rec.?  How good is the a/b rolling system?
Just a few questions before i cough up $8000.

My system consists of 

Video toaster 2.0
A2000
040/33mhz 16megs of ram
1.2 gig harddrive.
2 sony  PVM-1380 MOnitors
1 1084 monitor.
1 Panasonic AG450 Camera
1 Sony 1000a Laser Disc player.

I think thats about it..

Any thing i need to add to the system?  

Let me know..

	I noticed this a few months ago (right after I heard of
it here, in fact). There are some other night-time shows that
use it, but I can't remember the names right now.  
	If the camera remains still, and no-one moves, then the
effect is surprisingly realistic, but as soon as the camera or someone
moves, the effect is almost gone.

Keywords: full-motion video to workstation
Organization: Sandia National Laboratories, Albuquerque, NM
Date: Wed, 13 Jan 93 00:24:19 GMT

The Abekas Model A65 Component Digital Disk Recorder is
probably just what you want to load a bit of full-motion
broadcast video into your workstation.  This box can run
standalone (with its control panel) to record/play up to
about 25 seconds of video (about 800 frames) at a full
30 frames (60 fields) per second.  Around here, we use a
Sony D75 to "play" Betacam tapes into our Abekas. 
If your tape machine doesn't have CCIR-601 (component-digital)
outputs to plug into the Abekas A65, then you will 
also need an outboard A/D converter.  For use with
component-analog video, we have the Abekas
A25 for this -- I think we received one of the first A25s
from Abekas. (Its quite nice, but expensive.) 

Full-motion video, stripped down to just the displayed
image information, still comprises over 20 megabytes
per second of data -- probably too much for your workstation.
However, once your few seconds of video is on the A65, 
you can "rcp" the images, one at a time, to your workstation.
That's right, the A65 is a host on your Ethernet, and 
supports rcp (and ftp) transfers. Faster, but a lot less
standard, is a SCSI interface to the A65.

Of course, most folk use the A65 the other way around:
they render a frame at a time on their workstation (or
maybe a few at a time on their workstation farm), then
dump them to the A65. The A65, then, can "insert edit"
them all at once (up to 800, at least) to tape. The same
A65 (or A66, or even an old A60) does both functions.

One note: The Abekas digital disk products only store 
eight bits of luminance and color difference information.
If you are coming off videotape, I bet you didn't 
have 10-bit information anyway. If you are doing
analytic work from a live video source, you may want
to spend more and get a 10-bit A/D (I think BTS
makes a nice one) and choose a 10-bit capable 
digital disk from one of Abekas's competitors.

If you happen to have a supercomputer around, with a
HIPPI interface, you can do as we have also done --
build a little data reformatter to convert the 
CCIR601 video to HIPPI data bursts. The HIPPI speed
is 100 megabytes per second -- not a bottleneck.
However, 20 MB/sec is pretty fast, even for a
supercomputer. We are actually able
to send the full-motion CCIR-601 video from our
nCUBE computer with some careful nCUBE programming,
all the way to the CCIR-601 inputs of our D75.
The little data reformatter is just a couple of
Altera FPGA's and a HIPPI chipset -- cheap by 
digital video standards.

A short time ago, someone on the net mentioned a process called Filmlook
that was supposed to make video look like film, but at the time no one
seemed to have too much information.  Well, I just noticed today
while I was home at lunch flipping channels that Days of Our Lives is 
apparently using this process.  I don't watch this show so I don't know
how long they have been doing this but it caught my eye because it definitely
doesn't look like other soaps.  My first reaction was, "this looks almost
like it was shot on film", and sure enough, the closing credits list
Filmlook Inc. for image processing.  The process seems to work best for
shots that don't involve much movement, but whenever the camera panned
or there was fast movement, there was a noticeable strobe effect.  I had
to watch for a few minutes to make sure it wasn't supposed to be some kind
of flashback.  I would say the resulting effect is more of a cross between
film and video rather than a pure film look.  So, if anyone is curious about
this process, check out Days of Our Lives, especially if you can watch it
live and flip between Days and other soaps.

I want to take the plunge and go from a no-computer semi-manual
video editing system (Panasonic 1960s, Videonics titlemaker,
WJAVE-5 SEG, Futurevideo 1000Pro Mark II edit controller etc...)
to one that has a computer.

My questions and concerns are below.  Please post answers
even if you know to answers to just some of the questions.
Keep in mind that I edit fairly long (usually 1 hour) videos
and that I'm at the SVHS/Hi8 level of quality.

1) I know one day we'll just digitize the video onto optical disc
   and do non-linear on-line editing and then just "print to
   tape" at 30 fps, full screen etc...

How many years before this is practical and inexpensive (<$10,000) ?
Can any typical computer I buy today (e.g. Amiga 2000, Mac IIci, 486 PC)
be part of that future system?

2) In the meantime, I guess we have to edit on tape and use computers
   as fancy edit controllers/titlers/SEGs.

Is the AMIGA really still head and shoulders above the MAC and PC for
this application or have the MAC and PC made a lot of progress in the
last few months?

What are considered the BEST products for each of the three platforms
that don't cost a fortune and REALLY allow you to be productive in the
editing suite?

3) Is it yet possible to digitize a movie into QuickTime, create an
EDL with non-linear editing and then use the EDL on your tapes?

a) Doesn't it take a LONG time to digitize the video?
b) Don't you need HUGE hard disks?
c) Are the EDLs created in quicktime really compatible with
   the EDLs needed by the edit controller software?
d) Do you have to use SMTPE time code for this to be a real option?

4) Should I wait about another year to get computerized?
   I get the feeling that in about a year things will be much
more standardized, debugged and affordable than they are now. What
do you think?

 Thanks for your answers.

I know of no such ethernet-D1 VCR device, though I may be out of touch.

Related notions:
There are D1 VCR-based data storage devices which may take an ethernet
connection though they are usually configured for larger HIPPI size
connections.  They are not video capture devices though.  A true BTS or
Sony D1 VCR is a true video capture device.
The BTS DCR series d1 VCRs use a ethernet-like cable for communications
between some of their machines, though again, this has nothing to do with
actual image transfer.

The Abekas A60, A65 and A66 are hard disc recorders which can, with the
right options, record images over ethernet, slowly.  They can also, with
the optional A25 interface, digitize full bandwidth CCIR-601 video.  As can
RCI, Accom and other hard disc recorders.

Subject: Encoding My Own Surround Sound
Organization: University of Illinois at Urbana
Date: Wed, 6 Jan 1993 14:03:14 GMT

I'm interested in playing around with a simple method of recording
surround sound information onto my home-grown videotapes for playback
through a Dolby ProLogic surround decoder. I'd like to construct some
kind of black box which has inputs for left, right, center, and surround
channels, perhaps with some level controls for each input.

It seems to me that it wouldn't be too hard to do: the left and right
channels simply go straight to the left and right outputs. The center
channel input is sent to both left and right outputs in equal
proportion. The surround input would go unaltered to the right channel
and be phase-reversed for the left (by simply swapping the + and - leads
on the hookup wire between the surround input and the left channel
output). If possible, I'd like to get away without using any active
components.

This is a simple approach, and it sounds good on paper (at least with my
understanding of the way Dolby ProLogic surround works), but before I go
to the trouble of cobbling together such a device, I'm wondering if
anyone out there has actually experimented with something like this and,
if so, what your experiences were. Alternatively, if this design is
totally worthless and doomed to failure because my understanding of
Dolby ProLogic is flawed, I'd like to know about that, too. ;-)

So, what have people tried? What works, and what doesn't?

Thanks in advance for your input.

Hi Dave:

I recently put together a music video with some of my fellow workers for an
awards presentation.  This method may sound crude, but it ended up working
quite effectively.

In order to duplicate these steps, you must have a camcorder or VCR that 
can perform a Video Insert Edit, meaning the existing audio is left alone,
and the existing video is replaced by new video.

1)  I chose a CD as my source music.  Point the camcorder at the CD player
so the minutes and seconds for the music playing will be recorded along with
the audio of the music (use macro to focus on the LCD display).  Record the
entire song you wish to lip-sync to.

2)  Write a script for the song detailing what video image will go with each
segment of the song (i.e. 12 second segment from 1:45 to 1:57 will be John
on the drums, etc).

3)  Play back the CD through speakers for your actors, and let them know 
what segment they will be performing by cueing them from the CD player timer
as the music is played back for them.

4)  Record the video images of your actors, one segment at a time.  You have
two options here:  A) if your camcorder has video insert capability, and 
your actors usually get things right the first time, you may record directly
onto the original tape with the music and the CD player timer, replacing the
timer video with actor lip-sync video.  B) Record the actors lip-syncing 
onto the camcorder (multiple times, if needed), and then video insert these
images onto the original tape with music and CD timer, using a VCR with video
insert capability.

I probably made this sound more complicated than it really is.  Email me 
back if you have any questions.

Have fun,
Myron

While the encoding scheme for surround seems simple it is not and
cannot be done effectivly in a pasive manner.

There is also the all pass delays on the signal lines to consider.
These all pass delays need to be matched in the Left and right signal
paths.

The matrix also needs to be precision in the signal amplitude matching
If you matrix in the center channel signal with a 5% error then you
will effect the left and right channels as well.  A 5% error in
martixing the surround channel would effectivly distroy the stereo
signal as well.

I will be interested in others postings on this subject.  I would like
to find someone who has designed an encoder so I won't have to!
