Switching the scene automatically (video follows audio)
Here's how to automatically switch to the desired scene when the unit detects audio input that matches specific conditions (Video Follows Audio).
For example, if you're streaming a talk show or a conversation, you can use this to switch between a closeup of the individual who is speaking and
a wide shot of both people when neither person is speaking.
