Frank–Thank you for the input. The losses I refer to using Hi8 occur in generations all made with the 9700 which I assume uses internal Y-C dubbing. What I have been doing is editing on the 9700 (using Toaster for effects) and then transfering to VHS for distribution using a consumer VCR. My greatest losses actually occur in this last step. My thought is that since a professional S-VHS recorder has VHS capability, I will be able to make VHS copies using the S-VHS recorder and retain the Y-C dubbing. I am using a device made by CCI Electronics which converts the Toaster composite output to Y-C. I haven't noticed any losses attributable to the Toaster. At the same time, I am hopeful that the S-VHS setup will give me one more generation to play with—we'll see about that. Does any of this make sense ? I appreciate your help and am still grateful for your showing me how to put CG over framestores. Don't hesitate to tell me if I'm on the wrong track with the S-VHS plan. –\/ |<-

Van, unless you are using a tbc when you edit, you are going to incurr a loss of signal quality. The 9700 may in fact have internal YC, but I don't think it has a tbc correcting the signal during your edit. The other unit you described from CCI cannot increase your existing resolution, it can only make it possible for you to use the YC dub input on your SVHS machine. You could still see some benefit from using a TBC at this final stage, you might want to borrow or rent a transcoding tbc and experiment with it before you plunk down any money. Regards Frank

May I jump in with a question? Is a transcoding tbc a special breed? I have a newly-acquired toaster with a Personal TBC. I have been assuming that when I pass images from the player deck through the tbc, toaster etc. and out to the recorder deck, I would be getting better results than if I did a straight dub by connecting the two decks directly. Is this the case or do I need a different type of tbc? (Does one ever stop buying equipment when you get into video). Thanks, Barbara Andrew

Barbara, Welcome to the world of video. The "buying" never ends if you want to keep up with technology. In response to your question, your image quality will only be as good as the weakest link in your system. Yes, a transcoding TBC is different from your Personal TBC. And in some ways better, certainly more expensive. Your signal when using a TBC, is technically better than going from machine to machine. It may not be a visable difference on your edit master. You should however notice a difference when going another generation. There are better TBC's available. I try to think of the old hot rod saying "Speed costs money, how fast do you want to go?" when upgrading equipment. You can go faster, only you can decide if you need to. The next depressing time is when you find out how much your equipment is worth when you need to sell it at upgrade time. Karl – via Whap!

Karl, thanks for your reply. I'm not trying to go terrifically fast with this video setup, although I sometimes feel a bit of windburn when I find out about what other people are doing. Over the years I've always figured on a two-year payback timeframe for any equipment … I'm reluctantly having to change my mindset to a one-year term and refuse to admit to myself that it's really only about 3 weeks. I don't really consider the equipment to have any resale value (consequently I'm surrounded by old equipment — anyone want to buy an Osborne computer? only 10 years old). I still have tons to learn about video and there always seems to be just one more thing I really need to get. And I'm learning a lot from the chat in this forum. Thanks again. Barbara

Barbara, I see someone else responded to your question to me. Unfortunately the answer that was given was somewhat misleading. Let me set you straight. The Personal TBC WILL TRANSCODE SVHS and Hi-8 signals at a high enough bandwidth to give you better resolution than a plain composite signal for input to the Toaster. This of course presupposes that you: 1. Have either an SHVS or Hi-8 playback source. 2. Have set the proper jumpers on the Personal TBC card (as specified in your manual. Regarding your enquiry about straight VTR to VTR hookups as opposed to going through a TBC. You will indeed get better results using the TBC. You may quote me as follows: "To be in the video business , is to be in debt" I have yet to meet anyone in the biz who is free and clear, no matter how sucessful they become. There is ALWAYS some new technology that gobbles up a portion of your expendable cash and then some. Regards Frank

Hi Frank, nice to see you again…. I am dubbing SVHS tapes and own a PTBC II. Am I better off to go straight from deck to deck, or use the P TBC SVHS in and COMPOSITE out? –Paul < Motorola Inside > 😉

Paul, that depends on how good the composite input to your deck is. What you might gain in a Y358 dub without the TBC, can be sabatoged with tape transport induced time base error.The time base error comes from the playback deck, AND the record deck. Removing half of the time base error from the dub process by using a TBC will reduce perceptable generation loss greatly. I believe that it is a good rule of thumb to ALWAYS use a TBC when possible. Since your TBC only transcodes one way (S to composite) it is better than no tbc at all, but not quite as good as a TBC that processes YC throughout. BTW, it looks like we are getting quite a soaking from the storm (SJ area), how is it goping up your way? Regards Frank

Thanks for the help there Frank. Highway 101 was closed at the county line and I had some poor lady stuck in an elevator in greenbrae. Lady had to stand up for 2 hours, the floor was soaked, she said it was rain water. Rough day. Very wet. Russian River getting too high. Turned off pager.

If you go deck to deck in your S-VHS dubbing, you will elimanate the NTSC artifacting (i.e. Dot crawl)… Forrest

Frank, thank you for your answer. I see I was on the right track. I'm not looking for broadcast quality or anything, but I do want to get the end product as clear and sharp as I possibly can. It's a problem in this video area, people tell you they want something low budget, but sub-consciously they really expect the type of quality they're used to seeing on TV. I haven't yet found a way to explain they can't have both! Thanks again, Barbara.
