Activity Forums Apple Final Cut Pro X FCP AV OUTPUT

    I am not sure if FCP can see the Black Magic box I have attached to my Imac to get video output. A/V Output is grayed out, and if I go to Playback in Preferences, there is no mention of Black Magic under GPU. Any ideas? Thanks

    Going to need more info than Black Magic Box.

    Which unit? Which version of Blackmagic DesktopVideo are you running?

    How are you connecting to the unit?

    Operating system etc….

    Hi Eric, I’ve got FCP 10.5 on an Imac running Catalina 10.15.7 connected via Thunderbolt to a Black Magic AMA Radeon Pro 580 . Thanks Guy

    Hey Guy,

    This might sound silly, but I had this come up recently:
    Are you using a Thunderbolt cable between the iMac and the Blackmagic eGPU?

    As in many external SSD drives only ships with a USB C cable.
    And, if you in passing have grabbed one of those, the Mac may not see the Blackmagic.
