I have never really had problems livestreaming with vMix untill the past couple of weeks. I run a church livestream and we use Facebook and a thirdparty sermon site to host our streams. Very recently, the streams will dip framerates to like 1 every 2 or 3 seconds and choppy audio for 20-30 seconds. Then it returns to the normal speed. I'm not the most tech savvy guy in the world and I was wondering if anyone had ideas on what might be casuing this issue.

Thanks in advance.

Does the red stream button in vMix start flashing yellow when this happens?

Are you streaming directly to Facebook, or are you streaming to a 3rd party site like restream.io, which then restreams it to facebook?

My problem may be similar. I'm streaming directly to Facebook live. I'm not sure I'd call it "choppy" but FB does report a drop in the quality (red on the video stream graphic). The vmix "Stream" indicator will flash yellow.

I have a solid, hardwired, FIOS internet connection, so it's not that.

It can be so many things. Try to trace-route the facebook server to see where the issue might be. For a more constant monitoring you can download WinMTR. A change in DNS server might also change the route or provide a better entry point.
RTMP is unfortunately a very old protocol with no resiliance build in. If you find a service that supports SRT entry you might having less issues.
