#S-VHS for DTV setup?

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. Blaq!

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. Memeber of AMP Midgard Graphics

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. Regards, Gary

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). wmc – via Autopilot!

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!
