#3/4" or SVHS edit?

Hello folks: I'm at the early stages of planning an editing system for tapes mainly produced on a decent SVHS camera. But possibly from other formats like Hi-8 too. Like many of you, we're talking "home" , low budget equipment here. However instead of just getting a couple SVHS/VHS decks and a controller for starters (such as Pana AG-1970's) I've had some conversations and seen some newsletter type comments suggesting editing to a 3/4" tape system. Thus allowing less generational loss when editing and then copying again. I'm assuming used equipment here. Any opinions from "real" experience out there? I realize I have to end up making a final VHS tape someway at the end. But thought I might have more flexibility and sustaining of quality going 3/4" in between. Thanks, Dick

Any opinions from "real" experience out there? < Well, as someone who's tried it both ways–while 3/4" is preferable because you can get more composite info on the tape, you'll also need a time base corrector/digital frame buffer to get S-VHS quality (a component format) onto 3/4" (a composite format). Also, if you want any degree of edit control (which you'll need for 3/4", since I don't think any models come w/flying erase heads), you'll have to get a true industrial level S-VHS edit deck and an editing 3/4" deck, along w/a industrial level controller (don't have numbers offhand, but each is a couple thousand–used). For the level you're discussing, maybe editing S-VHS – S-VHS would be preferable, since everything more likely to be compatible that way. (Of course, if you want the best dub-down of S-VHS to VHS, you'll still need a TBC/frame buffer–like what comes w/SEGs like the Panasonic WJ-AVE-5 & 7, or the Videonics MX-1–but you can worry about that later.) Hope this helps, Tim Liebe

Dick, Im my opinion 3/4" is about dead. It may hold out more to multi-generation work, but as the power of doing more in "one-pass" continues to increase with DTV advances, multi-generational formats become secondary to higher quality first or second generational formats. I'd go with SVHS on the record side and maybe hi-8 on the source. -John

John: >Im my opinion 3/4" is about dead.< Not dead yet–it may pull through! <g> >It may hold out more to multi-generation work, but as the power of doing more in "one-pass" continues to increase with DTV advances, multi-generational formats become secondary to higher quality first or second generational formats.< But seriously, John… A good point. For putting together a tape, I'd recommend (and did, in fact) a setup much like the one you're discussing here. I still feel, however, that for a modestly-priced dub master, you can't beat 3/4"… Tim

John, if you master to Hi8 then you can use that master a do PCM audio dub … with the proper Hi8 deck of course. This will be MUCH better than the simple linear mono low fi audio dub of SVHS. The only way round this is to mix audio with initial assembly which will not give smooth transitions between cuts. Or suffer a generational loss with SVHS. Either SVHS or Hi8 the final target will probably be VHS for distribution. So I don't see the wisdom of going SVHS for master unless this is for personal use and this is all you're going to playback AND don't care about audio (unlikely). The issue of SVHS/VHS tape better standing up to repeated viewings than Hi8 notwithstanding. Am I overlooking something here? Thanks. -jts

John, So PCM gives Hi-8 decks a dubbable (dubable, dubabel, aargh) HI-Fi audio track, huh? Well that would be an advantage in linear audio editing, for sure. -John

One other consideration. When low cost NLE comes round then one could print to tape … any tape. If capturing in Hi8, well … it would make the most since to print directly to the distribution medium. Where SVHS or VHS. I would assume most would not distribute or maintain their own master copy in Hi8 unless more audio editing were envisioned. With NLE all audio could be added before printing to tape I believe. -jts
