Magic Music Visuals

Looking for assistance as Ive tried multiple capture cards and webcams as videocapture modules where they appear and are seen but no image comes through to be visible. Any thoughts?

Has anyone had success bringing in the Magewell SDI+ Capture card into Magic on a Mac as a video capture? Magic sees it but nothing comes up on screen? It shows as USB Capture SDI+ and if I open OBS to test the input, I see the camera image clear with no issues. Any idea how to solve this???
