Hiding Black Magic card from Media Composer

Is there a way to keep Media Composer from seeing my Black Magic video card? I don't use it to capture. I only use it for monitoring from Resolve. Is there a settings file I can edit to keep MC from seeing it?

Sorry...there was an option in MC5.5 to turn off the external devices. But that option went away in MC6.

You may want to try to use the terminal to load and unload the Decklink drivers. Drivers are referred to as kexts (kernel extensions)

Kext can be loaded and unloaded during runtime using the kextload and kextunload command lines.

in order to load kext, from terminal write:
sudo kextload kextName (where kextName stands for the kext name you want to load)
enter your password and press enter
the system should reply with a success or fail message.


in order to unload kext, from terminal write:
sudo kextunload kextName (where kextName stands for the kext name you want to unload)
enter your password and press enter
the system should reply with a success or fail message.


Since you may want to do this regularly, you might want to save it as a script.

I can confirm that the kextunload-trick works. You need the -b option though. This is the complete command:
sudo kextunload -p -b com.blackmagic-design.desktopvideo.iokit.driver

And to reload the driver:
sudo kextload -b com.blackmagic-design.desktopvideo.iokit.driver

Thanks!

I have MC6.5 and I can now turn it off.
