Have any of you Toaster users had any experience with either the DPS TBC IV or the DPS Personal Component Adapter? My local Toaster dealer tells me this combination does the same thing, at somewhat lower cost, than the Y/C Plus, i.e. that it allows input of S-video to the Toaster and Toaster output of S-video? Is my dealer confused on this? Thanks for the help. Tom

Thomas, Before you invest in any component adaptors, you might be interested in something I learned recently. NONE of the currently available products will passs actual YC THRU the Toaster. They may attatch to the pin type connectors on the Toaster board but they are still COMPOSITE branches of the same inputs/outputs that feed the BNC connectors. With Toaster's current design, it is impossible to "keep" the YC information seperated while the Toaster is processing it. All of the devices currently available and planned for release utilize some form of filtering technology to process some of the dot crawl and chroma shift, which makes the signal "appear" as though it were YC thrughout. Of the units that I have actually seen ,the Smith Audio Visual YC PLUS, the DPS component adaptor, and the Prime Image YC PLUS-PLUS, I am most impressed with the Prime Image unit. It doesn't require a slot and it allows selection of the Betacam/MII/SVHS outputs as well as the composite/SVHS inputs via an external switch. It retails for $699. If you want more direct info you can contact Prime Image at (408) 867-6519. As far as I know, they do NOT sell direct, you would still have to order the product through a dealer. Regards Frank

Frank, It's important information such as you have just provided me regarding the Personal Component Adapter that makes me feel like CIS is worth every penny! Thanks so very much for taking the time to point this out to me. I'll be talking with my dealer about this. Fortunately, my dealer is having some difficulties getting the DPS TBC IV's and the Personal Component Adapter so I have some time before laying my cash down. Obviously you have had a chance to directly see the output of these three component adapters. In your opinion do they make a significant improvemnt in the Toaster's output? I know this is asking for a judgment call on your part, but any information is better than none. My primary reason for getting the Personal TBC IV is that I have the original Personal TBC in my Toaster 2.0 system in my Amiga 2000, but with the purchase of the Toaster 4000 card I felt that I ought to upgrade my TBC's to the latest generation. My dealer then mentioned the Personal Component Adapter and it all seemed like a worthwhile thing to do. Let me hasten to add that I am not a video professional like yourself, but simply a serious video hobbyist. I do show my edited videos on a Sony 1042 commercial projector on a six ft high gain screen in my home and because of this larger image size I like to have the best quality Toaster output that I can afford. Frank, while I have your ear, I am becoming increasingly interested in non-linear editing. The recent issue of Desktop Video had some quite interesting articles on this subject. Do you first hand experience with any non-linear editing systems? Yes, I know that right now they are too expensive for a mere amateur, but I am hoping they will break the $3K price range sometime in the next year. Finally, I would like to thank you for the interesting questions and discussions that you often instigate on the Amiga forums. As a frequent "lurker" and sometime participant, I find these discussions always interesting and frequently useful. Tom

Thomas, Thanks for all the kudos, I am not certain I deserve all of them, but I'll take what I can get <g>. Regarding the component adaptors;l think that all three have a similar appearence with regard to filtering certain artifacts out of the video signal. I wouldn't say that one unit really offers a substantial improvement over the other. There is a slight edge to the YC Plus unit from Smith Audio/Visual, probably because of the Furudjia circuits. Your question about the TBC represents a valid consideration, since the specs on the original DPS board were not all that impressive compared to what is currently available. An upgrade might be in order,m but I wouldn't limit my choices to the DPS product line. Prime Image has a very good board that has impressive specs, but doesn't offer the kind of "tie-in" to other products/capabilities that the TBC IV offers. Regarding non-linear edit systems; My only direct experience has been with Mac based systems which were primarily designed to be used as "Off-Line" editing tools. Materials could be previewed in any of several versions the "Off-Line" before commiting to a final version which would be produced using the higher quality "On-Line" gear. It's becoming fairly obvious that new technology is fast approaching which will make broadcast quality non-linear hard disk based edit systems an affordable reality. I am hopeful that I will be able to take advantage of such a system as it becomes available. At the moment, no such system exists. Hopefully we might see something that we can all afford to buy within the next two to three years. Regards Frank

Frank, Again thanks for the useful information. I think your conclusion about non-linear editing becoming affordable over the next two to three years is quite correct. This may well be the next "revolution" in desktop video. NewTek has ocassionally mentioned that they are working on a product in this area. The near future should, indeed, be interesting! Tom

Is there any adaptor on the market that will allow me to go direct to the head-to-head input/output connectors on my U-Matic (Y-688) VTR's? HAve never seen anything advertised that will allow this type of Y/C transfer to/from my computer. Any information is appreciated! Alan Wolney

Alan, There are a couple of options, but they will only degrade or "filter" the signal somewhat. There's a composite-to-Y688 transcoder from a company called V.I.P., you will find their product in the current Markertek catalog. There are also some transcoding TBC units that will fit the bill. IMHO, you aren't really gaining anything by adding more circuitry to the signal path when attempting to go to Y688, since the composite input of your Umatic deck already handles the transcoding task for you.

Frank, I had no intention of going composite to y-688. I wanted to make SVHS to U-Matic transfers for editing purposes, and have a TBC inbetween the source and record U-Matic decks. When editing, the results look far cleaner when using the head to head dub connections, but would look even better if there were a y-688 TBC inbetween. Alan Wolney

Alan, There should be a VIP encoder model that does the trick (check Markertek catalog), if not I would contact Broadcast Systems design (see their ad in the current issue of Video Toaster User) and see if their model ten can transcode from "S" to Y-688. Frank
