I really want to use vMix to stream live to Facebook with 2 guests via vMix call.

Have been using Zoom.us up to now with no problems, but want to change as vMix offers a lot for functionality.

Today was the second week in a row that I have tried with vMix and at the last second as to revert to zoom to do it due to issues with vMix call.

The issue today was a delay in video; video freezing and poor audio quality with one guest (the other guest was fine)- I played with settings and could not sort.

At the last second we shut down vMix and went to Zoom and the video and audio from that guest was fine (so I assume that means the problem was not on her end)

Not sure where to start troubleshooting this ... anyone have any idea?

Test.....Test.....Test.....Test.....with your guests, well in advance of the show/

There are a number of factors to be aware of:

- Their basic ability to connect to vMix Call (ie not be blocked by a corp firewall)
- Their available bandwidth in both directions
- Their ability to select/use the correct audio device
- Their ability to select/use the correct camera
- Their computer's specifications
- Don't let them run any unnecessary programs that might slow the system
- Don't let them rely on Wi-Fi

If they have webcams don't reach for insanely high-resolution or frame-rates. Most built-in webcams can only support 720p30.

Zoom is itself a webrtc-based service. That is, if they're joining using a browser. It's just less bandwidth intensive since it's compositing the streams at the server.

Were you able to determine the issues you experienced and have you used vMix Call reliably since?

I ask because I too have been using Zoom (with Wirecast) for bringing in guests remotely and I'm experimenting with vMix and vMix Call. I'm wondering if there might be more of a chance of network congestion with the vMix WebRTC servers vs. Zoom's servers (if, for example, since Zoom's call service is core to their business, maybe they have more infrastructure in place to mitigate congestion?).

I've tried vMix Call once with two guests and it worked great. One came in via Firefox browser on a Windows 10 laptop; the other via Google Chrome on a Windows 10 laptop. I'm planning to experiment with it more soon.

Thanks.
