Capture dilemma: Use line TBC for old news footage?
2 Attachment(s)
Happy New Year to all.
I'm working on on a capture of an old news story that was recorded to a home VCR from a news broadcast about fifteen years ago. Samples are enclosed (they came straight out of VirtualDub). My equipment is a JVC SR-V101US and a BVTBC10 external TBC from LS. My dilemma with this tape is as follows:

Panasonic has a field TBC, essentially multi-line TBC, and is less prone to do this. But it's still not immune if the timing is really off/bad. Quote:

You need an ES10/15. :congrats: |
Thanks for the advice!

Third sample attached with TBC initially off and then turned on during the taking of the sample.

ES10/15 can be safe to buy on eBay.
However, remember these were consumer items, equally used by smart people, and the bucktooth numbnuts neighbor that plays his music too loud at 2am. Problems: - You want DVD recorder, not ash tray. If not confirmed non-smoking, avoid. If answer is "I don't know", assume smoking, avoid. If seller sniffs it and "smells nothing", assume seller couldn't smell fart from a skunk, avoid. Trust me, I've been through that BS many times (not with ES10/15, or even video equipment, but other items). Learned my lesson, you learn from me. People get lung cancer (tar buildup, etc), but so do items. - Pets are nice, but not near video electronics. If not pet-free home, assume it's full of dog/cat/whatever hair and dander. Again, been there, done that. - Kids are dumb with electronics. You want to know how it was used, who used it. Otherwise it could be full of LEGOs, old PB&J sandwich, snot boogers, etc. In fact, assume that's the case, unless given info to the contrary. eBay is a gamble. It's hard to screw up the ES10/15, but certainly not impossible. Do your research, ask questions, try to minimize your risk. Realize that most sellers lie and BS to sell stuff, so you need to watch for weasel statements. Anything improper, any uneasy feelings, no deal, move on, regardless of how tempting to price. |

Can I get the cheat sheet? Was that 4th new capture unchanged?

I also noticed that the frame TBC is darkening the levels and smearing the chroma a little bit. |

But ES10/15 probably still in your future. That's ugly source. |

I see zero chroma smearing. I just looked at the samples in 2x on my calibrated video system. :question: |

Has Frame TBC

It's best to have line TBC off on the JVC deck to allow the ES15 to do its job, I understand. |

Alrighty, well, the Panasonic ES15 showed up, I added it to the workflow, and... the frame jumps are as effectively neutralized as I could have hoped for. Thank you, LS! Here's Sample E.

Except now you have to choose between the line wiggle or the frame jump, What happens when you turn on the VCR's line TBC while the ES15 in line?

- JVC TBC on = ES10/15 TBC(ish) does nothing - JVC TBC off = signal passed to ES10/15 for processing, signal TBC(ish)'d The -ish is because it's a crippled TBC, thanks for anti-copy. You rarely see tearing/wiggle pass, but other issues can come up frame still required the actual frame TBC. Anyway -- there's no wiggle there. :wink2: (Yes, yes, slight wiggle, TBC can never 100% perfectly pixel-lock. But this is better than the JVC was doing, and far better than sans-TBC.) |
