Atem Mini webcam source black on macOS

Hello,
I have an Atom Mini Pro connected via USB-C to my Mac Book Pro (Ventura 13.2). I can see switcher via ATEM Software Controller. However the webcam source shows completely black. The audio is coming through. I tried with faceTime, Photo Booth and WebEx, the video is always black. I rebooted the switcher and sill black. What can I do to fix this?

And do u switched any input to program ?

Video out is set to M/V. I tried 1,2,3,4 and PGM.

After various tentatives I can output still images, but not video output.

That's a very famous bug and there are lot's of threads written here:

To solve it you have to power off/on the Atem and then you will have an image on the USB webcam output.
Till now Blackmagic don't have a solution for this longlasting problem.

I tried it all and nothing. Reboot the ATEM, tried with both MacBook M1 and Intel, nothing seem to work. Only still images, but no video

But do you have video on your multiview in the program window?

I am quite new to this switch. I checked the preview and video is black too.

Perhaps that is the problem. I am using two iPhone as camera.

U must see camera inputs in multiviewer .. And after that , u can switch any camera to PGM output or PREVIEW ..

I finally found out the issue was resolved after downloading the lightning HDMI adapter firmware for iPhone. For some reasons the message was not shown before. After a reboot I got the notification, accepted and it started working.
