Hi.
Sorry to take so long but I posted this question a few times with no replies. It’s nice to see some suggestiopns, thank you all.
To answer Bob’s questions:
1 – Yes, we have One single TBC feeding the deck. then I loop the black through the deck and out to the genlock input of the decklink card. I don’t output black to deck during capture (just to let you know).
2 – The VTR I’m using is a SONY PVW-2800. I’ve also tried using a Sony UVW-1800 with similar results.
I guess the test now is to try blacking a tape using the 4 field option, then to output from the AVID, then digitize in FCP with the decklink, then lay back to the same tape. IF there’s srtill a shift then I’ll know it’s something else…
I discussed this issue a long time ago with some of the BMD staff and in the end it was what they called analogue blanking… A term I’m not familiar with, but perhaps it’s another word for teh same thing.
Thanks again for your help.
Kai
