If you have set up your Studio to live stream to another platform like YouTube or Twitch, the audio/video from your Studio appears on the other website only while you are recording.
Any participant (Host, Guest, or Producer) with their camera on appears on the live stream, including in Studios set to only record audio.
If a participant has their camera off but their microphone on, they can still be heard.
If all participants have their cameras off or the Host enables Low Data Mode, then the live stream video displays as a solid black square (like in the example image below).
NOTE: Live Video Delay
There is usually a short delay, or latency, between the Studio recording and the live stream on the other platform. It can vary depending on the other platform's settings and is generally around 20 seconds.
