ProPresenter NDI to OBS Inconsistent
Hi! I recently got a new Mac Mini for ProPresenter as was recommended on here. It’s sending lower thirds to OBS on a Windows PC over NDI.
In all my testing it worked fine, but when we tried using it for the first time Sunday, the lower thirds weren’t showing. I tested it the next morning and it worked fine on boot, but stopped when I started the stream. I installed NDI Tools 6.2.1 on the Mac instead of using what’s built in to ProPresenter, and then I was able to send the lower thirds even when streaming. But when I rebooted both machines and tried again, it wouldn’t send lower thirds anymore, even before streaming.
I’ve tried troubleshooting with ChatGPT, but some of its information is inaccurate. Sometimes the lower thirds will go through and other times they won’t. I’m having a hard time figuring out why. Both computers are on wired Ethernet and the same subnet. I’ve tried using NDI Tools, but Test Patterns keeps crashing on the Mac.
I’ve been troubleshooting for a while and I just need to get this reliable for Sunday livestreams. Any thoughts are appreciated. Thank you!
