  • Device Control with a JVC CR-850U

    Posted by Jeffrey Lonigro on April 7, 2008 at 12:08 am

    I am having an issue using FCP 5.04 an AJA IO and a JVC CR-850U 3/4″ deck. When I hit the space bar in log and capture the tape rolls but if I hit it again to stop it doesn’t stop. The same thing happens with hitting k on the keyboard. Hitting J and K works fine and if I click on the controls using the mouse that works fine. I have it sety for Sony RS422.

    that is an OS / configuration error.

    what computer and OS are you running?

    How is the deck connected to the Io.

    [Jeffrey Lonigro] “OS 10.4.11 “

    5.04 is not certified for that os

    what deck control protocol are you using ( there is not one for JVC)

    What version of FCP is certified? I think there is a JVC protocol but it’s RS232? I had Sony RS422 selected. I think I tried others but that didn’t solve it.

    [Jeffrey Lonigro] “What version of FCP is certified?”

    its more like your FCP was not made for the QT version you are running – I believe that 5.0 shipped with QT 6x. NOT the 7.4 you are most likely running.

    As for device control- my guess is that the Sony protocol has the stop / start settings to run differently than JVC does and if that is the case you are plain out of luck.

    Don’t forget – it may just be the deck- they are quite long in the tooth for usage- ( I have not worked on a 3/4 deck in over 10 years)

    that’s what i was think as well. Someone else suggested the quicktime issue. would it be advised to downgrade back to a previous version? if so what’s the best way and what version would you suggest?
