	- Hypertext Models: Dexter, Trellis,
	- Proposals and Extensions for Multimedia,
	- Data bases for Hypermedia,
	- A most recent Bibliography of Hypertext and Hypermedia.

He asked me to send this posting to the news group, because the news system is

I'm using a RasterOPs Video Expander II and a RasterOps 24XLTV board on
a Mac to put out a comp video signal to a Panasonic 4 head VHS VCR. 
Problem is, although the picture looks great on the computer monitor, and it
looks pretty good on a video monitor, it looks like crap when played back.

There is a lot of computer equipment running, any chance that all the stray
RF is hosing up the VCR?

If I switch to SVHS, will I get a better picture?  If so, how much better?

Any thing I could add to filter or improve the signal?

Thanks!

Hi,
well there was on older E82 model, but the new one comes directly with
this new RS232 inertface developed by GSE (Rapid Timecode).

Also the E82 was to be said to have one of the best SVHS picture
quality in the consumer field. It has about 4.8 Mhz at -10 dB
bandwith.

Hope this helps.

Hello everybody,

I have been sorking on an interactive program in which I would like to
play a series of sounds using lingo.  Unfortunately all of my tests have
indicated that you can only call one sound per handler.  For example:

on soundPlayer
  puppetSound "smoking?"
  puppetSound "uno"
  puppetSound "cinco"
end soundPlayer

results in only playing the sound "cinco".

Has anybody else encountered this problem?  Does anybody have any
solutions?  Should I post this to another newsgroup?  Does Macromedia
have an internet address?  Any help would be greatly appreciated.

I purchased the MediaVision MM Upgrade Kit.  It does come with an NEC 83J. I
called NEC tech support and asked them the differences between an 83J, 83M
and 84.  NEC tech support told me an 83J and 83M are IDENTICAL except for
the model number, 83J is used for OEM drives.  The 84 adds an external dust
door to help prevent dust from entering the drive.  Other than the dust door
all three drives have IDENTICAL capabilities and performance.  Note, this 
data is from NEC tech support (the manufacturer).

If it matters, I'm extremely pleased with my purchase.

I'm afraid there's something important I forgot to tell about this...

I thought we did the test with original PAL-tapes,
but I now found out that they were coded according
to the CCITT rec. H.261-standard. This is a videophone
standard for coding pictures at around 64 Kbit/sec.
I f you are not familiar with this: it means a lot of
data-reduction. The result is that the frame rate was
around 10 Hz, and the pictures are of less quality than 
PAL. 

I will receive more accurate details in a few days,
but the average error was over 150 msec, in either
direction.
 
I intend to do the tests again with non-coded material as
soon as I have the equipment back, but this can take a while,
as it's now being used outside of our lab.
I wonder how well people will perform on the original tapes ...

I'm sorry for the inaccuracy in my orignal posting,

	Ah, I suggest you read the programmers manual of the Sound Blaster...
I don't have it at work with me, but you'll notice that the sampling
frequency is stored in a specific format... Just count the bits, and you'll
get the acuracy with which the sampling frequency is defined... That should
help you...

	As an example, say you're using 8 bits to define a frequency... And
Your Frequence can go from 0 to 22000 Hz... Then you have a 86 Hz acuracy.
At 11000 KHz, it's 43 Hz...  And so on... 440 Hz give 2 Hz accuracy.

	Does this help?

Gilles.

We are getting to the final stages of specifying a multimedia system for
training purposes.  We decided to use DVI technology instead of a VCR or
laserdisc player.  IBM's ActionMedia II board set/software package fits
our requirements perfectly.  However, the IBM rep. we spoke with said
that the video output resolution was fuzzy.  The reviews I have seen
have all said that ActionMedia video quality is not production quality, but
it is adequate for training and presentations.

My question is to anyone who is using this board set:  How fuzzy is the
resolution and is it adequate for training purposes?

We are using a DEC 486/33 with Asymetrix Multimedia Toolbook for authoring,
and a 16" monitor with 1024x768 resolution.

Any answers (either post or e-mail) would be greatly appreciated.  We are
ready to order this board set.  However, we want to check on the resolution
issue before actually committing.

Subject: Re: lip sync
Date: 13 Aug 92 15:15:55 GMT
Organization: GTE Laboratories, Waltham, MA

speaking as a filmmaker in a former life, i've found
that a professional film editor knows when something
is even 1 frame out of sync (that's at 24 fps for film).

in my experience, a general audience can't tell the 
difference at 1 frame out; they may sense something is wrong
at 2 frames out, but don't know quite what; and at 3 or more
frames out, everybody seems to know what's wrong. 

on a 16mm film projector, the optical sound track is ahead
of the picture by some number of frames; the advance is 20 
for 35mm, i'm not sure about 16mm. this is because the film
must be travelling at a constant velocity when it goes over 
the audio playback head, but the film must be held still for 
picture projection. every 1/48 of second the projector's 
shutter opens and displays a frame frozen in the gate. then 
the shutter closes and the film advances to the next frame 
during the following 1/48 of a second, while the screen is black.
several spring-loaded rollers help to smooth out the jitter 
in the film's velocity before it hits the sound head.

note that there must be exactly 20 frames between the gate and 
the sound pickup to play synchronized sound. when threading, the 
size of the bottom loop is the most critical factor. if the loop
is too small, the sound is early; if the loop is too big, the sound
is late. thanks to armies of amateur operators, whole generations 
of elementary school students have grown up watching 16mm films 
out of sync for this very reason. perhaps this explains a certain
insensitivity to this problem among general audiences ... :)

as to whether early or late makes a difference, i'm told
that being early with sound is much worse than being late;
and logically that would seem to make sense; but in my 
experience it didn't matter. i have known experts who could 
tell pretty quickly whether sound was ahead or behind of 
the pix, but most people don't have a clue about the 
direction of the delay when it's under 1/2 second. i know
i didn't; i always had a tough time syncing up wild tracks 
where there was no slate. back and forth, back and forth 
i'd go ...

try editing film on a Steenbeck flatbed some time. since you
have separate sound and picture tracks, it's real easy to 
slip frames back and forth to experience the effect.

	Based on the hardware configuration, it sounds like you don't want
a low-end sound card.  The Sound Blaster is adequate, and it is supported
by almost every software product, but technically, it sucks.  I've used 
SB's  in mutlimedia kiosks for some time now, only because of price.  The
company (not UNISYS) also used other cards, and out of the two choices
you list, the Pro Audio Spectrum is definitely worth the extra $100 or so
(retail).  SB has a lousy ground design which causes hum and buzz, and don't
ask about the gutless amp.
    The MediaVision card(ProAud..) is a next generation card, and has the
    capabilities to prove it.

I'm no expert on sound cards, but this is based on personal experience.  Buy
a Sound Blaster if you want cheap, and a Pro Audio Spectrum if you want 
better sound capabilities.
