Hi

New to OBS. I want to record a music performance (audio sync is important)

So for I am trying to mix 2-3 different angle using NDI sources (iphone and ipad) and a usb webcam. At first , all are off with audio and from one another. So I offset the audio and add rendey delay to the sources so that all is in sync

The problem is that over a short period of time, they all get somewhat out of sync again. And if I turn off/on one of the source, the offset is different again.

so my question is,what can I do to nail the difference and have it consistent over time?
