We have tried changing the latency and it does not seem to work for our case as the error keeps re-occurring during the show.
The video will stutter very often.
We confirmed it is Aximmetry's NDI issue as the NDI Studio Monitor was smooth.
Because of that, I had the idea of using the NDI webcam to bring in the video and audio, and it worked smoothly.
Please update us as soon as you can for this fix.
Also, we noticed that the rendering fluxes more often Sometimes faster, and sometimes slower than the audio. But this is after over 6 hours of stream we had done.
I had a similar issue with stuttering video.
We tried to sniff the network packets - see if something cause for the bottle neck.
Eventually, the solution for that was simply - changing the network cable - seriously !!
