Please clarify your question. Are you asking about trying to CONTROL the tape decks (using the RS-422 interface)? Or are you asking about simply digitizing the VIDEO signal for input to your computer?
I would start with the video first. Whatever standard your tape deck puts out (NTSC, PAL, etc.) you should set the DeckLink to a compatible video standard. Once that is operating properly, THEN I would tackle the deck control (RS-422).
I am a new user to black magic decklink, Before that i edit on footages from 5d mark 2 in which i just convert the footage and start my edit but now i have to dump serveral kind of tapes like.
Organization where i am working now they use decklink for capturing the tapes. I want to know that what setting should be made to the decklink while dumping through:- Betacam recorder, Hdcam recorder & others.
Tutorial is requested about the basiscs of how to use a black magic decklink.
