Having Issues Previewing GoPro Hero9 feed from ATEM Mini

[fmckinnon]

Hey Gang,
I'm having issues viewing my GoPro Hero9 in OBS. I'm sending it through an ATEM Mini. I'm not using the HDMI out into my iMac, because I don't have a cable that is HDMI out to either USB or USB-C in ... (I'm on an older iMac with Monterey) ... but I'm using the webcam out of the ATEM. I can preview the color bars, so I feel confident that signal is coming from the ATEM into OBS as a video capture device.

99% sure this is a GoPro issue, but thought I'd ask here ...
I've got a quick video I made for "TJ", a local video producer who helped me with purchasing some gear, but haven't gotten any help, so posted it as a private link on YouTube here:

SOLVED:

You'll never guess. So who would've known (not me) that some HDMI cables (ie. all of mine that I bought and kept trying) require you to plug the CORRECT END of the HDMI cable into the mixer vs the camera. Since both ends look identical - and the ports are identical, I was not aware that one end had a "To Source" icon on it, and the other end had a "To Display" icon on it.

My local video guy finally called me back - to his credit, he's been really sick and in bed. He said the cables I bought are long, and have fiber optic conversion happening at both ends, so you have to use the correct end.

Literally unplugged and reversed which end of the cable I was using, and it worked.

I spent almost a week troubleshooting this and almost packed the whole pack full of gear up and shipped it back over plugging in the wrong end of the cable.

I NEVER KNEW THERE WAS A "CORRECT" END OF A HDMI CABLE
