#S-VHS for DTV setup?
6 messages in this thread
I'd like your advice on whether to get an S-VHS rather than VHS VCR.
Currently, none of my gear is set up for S-VHS, but one has to start
somewhere. I would especially like information on how much value an S-VHS
VCR would add to my desktop video setup — or would it? Here's the list:
WHAT I HAVE
———–
.
.Sony SLV-757 VCR
.
.– inputs: Amiga 3000 with 24-bit graphics board
. has 24-bit graphics output
. 6-year old Zenith video camera (not camcorder),
. used with copy stand only
. Your standard cable descrambler and converter
. Panasonic TQ-2022 videodisc recorder
. basically, a recordable laserdisc — BUT with
. VHS quality only, and dropouts. NOT the
. crystal-clear image people imagine when
. they hear "laserdisc".
.
.– outputs: 8-year old 28" Sanyo TV/monitor.
. DCTV slow-scan digitizer for the Amiga
. The recordable laserdisc, to capture moving video
.
WHAT I DO WITH IT
—————–
.
Input to the VCR:
I can animate in real-time using my Amiga and DCTV, which doubles as an
output device — a composite encoder which uses proprietary image
compression to turn a 16-color AMiga display into a reasonable facsimile
of a full-color NTSC image. And animates as fast as the Amiga could
animate any 16-color picture, too.
Usually, though, I render 3-D animation and single-frame them onto my
optical disc, where they can be played at full 30 fps, or faster, or
slower, forwards and backwards. It makes for a great still-store, too.
Output from the VCR:
I don't grab images off the VCR; they're too fuzzy and have too many color
artifacts. I might record 5 seconds of something off the air onto the
optical disc and digitize _that_; the still image should be much better
than my VCR.
Currently, I only output from my VCR to watch something. I'll occasionally
dump some graphics on tape and bring the tape to my local Amiga animators'
meeting.
.
All the devices I own only have composite video connectors. None supports
S-video.
.

MY PLANS FOR THE FUTURE
———————–
.
I hope to do computer animation on the side. If you forget the VCR for a
moment, my setup is good enough for industrials; I have friend who earn
their living doing this with similar setups. Eventually, I hope to add a
second VCR, enabling me to do all sorts of editing, such as building a
demo reel at home. To me, S-VHS hits my target market of low-grade
videographers whose clients may want some flying logos to spruce things
up. I don't feel anything better is worth the considerable expense,
considering that my optical disc unit, on which all my animations get
recorded, is VHS-quality only. If a client wants my output on Betacam,
I'll simply rent a Betacam deck for the day. (He'll still get a
VHS-quality animation on his Betacam tape, though)
.
.
.MY QUESTIONS TO YOU
——————–
.
Considering that the rest of my gear is VHS-quality, and has no S-VHS
connectors, would I gain anything by replacing my VHS VCR by an S-VHS
one?.
Would an S-VHS VCR show better quality when playing back recordings, even
if the incoming signal was plain old composite video, rather than S-video?
(I know the biggest difference comes from recording with S-video — GIGO,
after all)
Would easy access to the S-VHS format help me sell services to S-VHS
customers? (Obviously, right?)
When editing, would generation loss be much smaller with S-VHS?
And what if I couldn't hook up my editing machines through an S-VHS path?
(For example, if I want to overlay computer titles, effects, or more
animations on top of the source image, I need to run the signal through my
composite-only genlock)
.
.
BONUS QUESTION
————–
.
My Sony SLV-757 has been in the shop for weeks. Now I learn they've lost
it, and all 3 parties (the store, the service center, and Sony) will chip
in to get me a new replacement unit. At this point, I'm thinking "why not
pay the difference and have them send me an SLV-R5 instead?" Which brought
on this whole "to S- or not to S-" dilemma.
From reading other messages in CEVideo, it seems like the SLV-R5 is a
better Sony choice than the newer model. Does everyone agree?
Many thanks for all your help.

Aloha BLAQ! I am ALSO not really setup for SVHS but I own a SVHS VCR, I
strongly suggest taking a look at the JVC HR4700U, it has flying erase
heads and Hi Fi sound and only cost me $420 2 years ago.

Blaq, There is no question that SVHS will outperform VHS in almost every regard
(even when the inpit is composite). The Sony SLV-R5U is no longer available. It
was replaced with the SL-1000. Most agree that this was a mistake.
I happen to have two JVC SVHS decks for sale. A used one for $400. An a new one
for $600. They are both Model HRS-660. Excellent editing machine. E-mail me if
you want mor information.

Blaq,
S-VHS gives almost 2x the resolution of VHS. You can see the difference
and it is significant enough that you can see the difference even without
doing a "side by side" type comparison.
If your composite source is outputting a high frequency signal with
quality at the hihger end (like 5.5 Mhz or better) the recording in S-VHS
will capture more detail.
If you want to go "whole hog" Sony has an industrial/high-end consumer
SVHS deck. JVC's BRS-805/605s are nice.
Or, you can save up your dough and get a low end Beta-SP for about $7500
(UVW-1800).

Maybe you should invest in a better animation system – like a PAR.
Your right, if you have the local resources, you can rent a tape machine
for a day and deliver on various formats. I don't know, It seems, from the
info, that you are an animPhile as opposed to a VidiDroid (like myself).
I have been working with Panasonic 76 & 7750 S VHS decks. I don't think
you can go wrong by upgrading to an S deck(s). Even if you can't output
Y/C (S-VHS signal) you might be able to in the future. Plus, you have to
consider what type of post-production facility your work is going to be
run through. If you are not planning to get into full scale video
production it might be worth it, for now, to get an Amiga/LaserDisk link
up with a post production facility. Could you take your LaserDisk player
into the post house and dump onto whatever tape format they will be
mastering on or, would it be possible to go directly onto the master from
LDisk?
VHS quality onto Beta will still be VHS quality but when you go to
insert your Beta'd VHS into a edited Master that is made up of Beta field
footage, delivering on Beta, will be a lot better than delivering on VHS
(or S-VHS) because 1) you have a better transer from you Laser Disk, and
2) your the generation loss will be smaller when going to the master tape.
BTW, my experience with video is GI(G+xy)O in which x=the generation
loss of your tape format and y= system calibrations (phase,levels etc).
Michael,
I'd rather buy an '040 accelerator than a PAR; it would give me much, much
more bang for the buck. One thing I like about recordable optical discs is
their archival ability: every bit of experimental crap I've ever produced
is on the disc, ready to be played to long-suffering friends. <g> Oh, and
I'd never dream about carrying my optical disc recorder around. It weighs
a ton, and I got it for $15,000 off <bg> so I consider an irreplaceable,
one-of-a-kind unit. Heck, repairs on that industrial behemoth would
probably cost more than a PAR. And I wouldn't have the archival
capability.
The many replies I've received, here, and in CEVideo, have got me
convinced. My next purchase will not be an accelerator as I'd thought, but
a S-VHS VCR.
Blaq!
