Hi vMix Forum,
We’re a production team in Germany planning to connect with a talent currently in China. Our goal is to use vMix (specifically vMix Calls) to bring their camera and microphone feed into our production here in Germany.

Questions:

1. Has anyone used vMix Calls to connect with participants in China? If so, what was your experience with latency, reliability, and overall quality?
   
2. Are there any known issues or workarounds for using vMix Calls between Europe and China (e.g., firewall restrictions, VPNs, or specific settings)?
   
3. As a sidenote: We’ll also be sending an RTMP feed from Europe to China for the talent to react to. Has anyone successfully received RTMP streams in China from Europe? Any tips or pitfalls to avoid?

Context:

• Our setup includes vMix for production, and we’re open to suggestions for alternative tools if vMix Calls isn’t ideal for this scenario.
  
• The talent in China will need to receive both the RTMP feed and participate in the vMix Call simultaneously.

Thanks in advance for any insights or shared experiences!
