TBC Questions

[jriker1]

I am looking to buy a Time Based Corrector, specifically the TV One 1T-TBC. Had some questions about it:

1. Has anyone used this unit specifically and have any opinions on it?
2. The back of the unit supposably supports composite and S-video connectors, however the CV connectors, as labeled in the picture below, do not look like any composite connections I have seen.

3. For $90 more, should I be considering the 1T-TBC-GL which has Gen-Lock?

4. If yes to 3, can someone please describe how Gen-Lock works? Read a lot about it however still not sure when it would really be needed and if it's just as simple as plugging a second VCR into the GenLock ports, picking any VHS tape, and running it in parallel to the primary tape.

Also note, if it makes any difference on the Gen-Lock questions, that I will only be using the S-Video connections to dub to my Canopus ADVC110 DV device on the computer.

Thanks.

That's a BNC - Bayonet Neill Concelman - connection; pretty much a standard for professional video. You can buy BNC cables or a BNC-RCA adapter easily.

3. For $90 more, should I be considering the 1T-TBC-GL which has Gen-Lock?TVOne used to make a scan converter/genlock called the Deltascan which was one of the worst genlocks I have ever had the misfortune to use. It had a cheap burst synch crystal which made it virtually useless for its intended purpose. It was also luma key only, which was just insult to injury.

Unless you're going to perform real-time switching or mixing of two or more sources before capture then you don't really need genlocking. The ADVC110 accepts only one signal at a time so, on its own, there's not much need for reference sync.

OK, So I got the TVOne unit. I now have a full three hours of video coming into the PC. So new issue. The top of the video has a tearing effect in it and there are very very thin horizontal wavy black lines going thru it. Something you hardly see on the TV from a distance and even less so if I run it thru NeatVideo cleanup. If I went with a DataVideo TBC-1000 unit instead, do you think it would work any differently or are they are about the same at the $400-500 cost point? What I am getting now is acceptable, however obviously worse than what one would see directly to the TV from the VCR. I am thinking of trying the TBC-1000 however it will be a big hastle since I now own the TVOne unit so would be a lot of back and forth and returns. Thoughts on this?

Thanks.

Without seeing a sample frame, it's hard to say. What is the source of the S-video signal? VHS/S-VHS or a live broadcast? You might just be seeing the usual distortions at the top and bottom of consumer video that are normally hidden due to overscanning. You may also be seeing Line 21 data etc.

Any chance of a sample frame?

The closest example I can show you as I deleted the original conversion and have sent the TBC back for a different one (cables were missing from the box), is this link:

Now picture the above, however also with these real thin wavy lines that are consistant thruout. Also I have heard mention of this Line 21 data. What is that about?
