Thank you. This is important information:

UPDATE: I figured out my problem.
For the Intel Mac-
Before Desktop Video can work properly it must be authorized by the user. Open System Preferences/Security & Privacy and on the General tab there should be a message about Desktop Video asking for permission to the system. Click the lock icon, enter your Admin password and authorize Desktop Video. That fixed the problem for me. Desktop Video recognized the UltraStudio Recorder and I had the option to use either SDI or HDMI input.
For the M1 MacBook Air-
A similar situation except there were message bubbles that warned that authorization was needed and gave instructions for shutting down and rebooting in a special way, holding the Touch ID power button until you enter a special boot mode to authorize Desktop Video. After authorizing and rebooting go back to System Preferences/Security & Privacy and make sure Desktop Video isn't asking for permission. Desktop Video should launch from the System Preferences then and you can configure the UltraStudio Recorder when it's connected.
All of this explicit authorization is something new for Mac users. Most every app that's installed and wants access to the system seems to need to be given explicit permission now in the Security & Privacy section of the System Preferences.
