I've been using OBS for a few months now, and the past few weeks I've run into the audio getting out of sync. It starts in sync, but it seems to at certain points just lose about a second= the audio is ahead of the video. I know you can delay the audio, but it can be in sync at first, and then out of sync later so that's not really helping me. I have been working for a few weeks to try to figure out what might be causing it, and I think that when I switch to the NDI input for a minute or longer, when I cut back to the ATEM, it's out of sync. I was just wondering if anyone else had seen switching back and forth to an NDI source cause the audio to lose sync. Or if you've run into it using an ATEM and an NDI. Thanks for any help or ideas to try.
Here's the way I've got it setup.
Mac running OBS with an ATEM Mini Pro to switch between two HDMI sources. This is routed in as a Video source.
NDI source routed in from another mac that is running ProPresenter. The Mac with OBS is using NDI Syphon to see the ProPresenter screen.
The audio is routed from the ATEM mic input into the OBS Mic/Aux.
