OBS not recognizing Blackmagic Device

[Frank Diskin]

I recently upgraded to Big Sur and cannot get my Blackmagic UltraStudio Mini Recorder to work in OBS. The option "Blackmagic Device" is available in the list of sources but but cannot be found under source properties. It just shows a check mark where my device should be listed. I am able to use the internal camera of the Mac as a video capture device but my Blackmagic won't work. Everything worked fine with Catalina so I'm wondering if this is a Big Sur issue.

Have you updated your BlackMagic drivers? They did a big sur update and it took a couple of reinstalls for me to get it to work again.

I am running into the same issue. I have installed Blackmagic's 11.7 and 12.0 Beta drivers... no luck on getting any signal to my computer from my Blackmagic intensity shuttle thunderbolt. I've done the install and reinstall close to 5 times. Any leads would be great.

I contacted them, I think they need people to trouble shoot.

Sometimes giving the drivers permissions in Mac screws up but I swear I gave it permission everytime and it worked on like the 6th try,

+1 on this thread. Had a major fail at a multi cam live stream yesterday. Plugging in my UltraStudio Recorder 3g froze OBS every time. Never got picture either.
