Answers.Body: <p>It's a green screen, otherwise known as chroma keying.  Blue is also used, especially for blonde subjects, or people in green clothing/ costume.  It's not being projected behind him.  If you were standing in the room, you'd just see a green wall.  But it is possible to key footage live, and even to stream a live chroma key.  You just need the right hardware and/ or software.  </p>

Answers.Text: If you want to stream live, Wirecast provides luma and chroma keying options. My studio used Wirecast for many years before upgrading to a Black Magic ATEM 1 M/E, at roughly the same total cost as a PC and hardware capable of handling Wirecast.

  I don't think you can achieve this on a live webcast with only a laptop. You will want either:
  
  1. a dedicated PC with an I7 or better CPU, appropriate video hardware (Blackmagic capture card or comparable) and software switch (Wirecast or comparable), or
  2. a hardware video switch (Blackmagic ATEM 1 M/E or comparable).
  
  Having purchased both types of systems in the past few years, the two options come out to about the same price, and I'm partial to the hardware solution.
