Question / Help Audio Loses Sync within One Second

Hi,
I'm using the OBS Camera plugin to shoot video from my iPhone11, and the Focusrite Scarlett Audio interface to bring audio from my wireless mic into OBS. Working on a 2018 Macbook Air running 10.14.

I shot a test video with this new set up, to figure out the lag offset. In iMovie I could sync up audio and video at the beginning, but within one second the audio was several frames out of sync. Oddly, the audio sounds fine and the video looks fine, it just won't hold sync. The other odd thing is that each time I shot a new test video the lag was different, it ranged form 100ms to 1600ms.

I'd greatly appreciate any help in troubleshooting. This is so strange, I don't even know where to start.

Here's the log file:

Thanks so much!
Bruce
