Using Blackmagic ATEM Television Studio Switcher

Hello everyone,

I was recently introduced to this cool software and I am now trying to get my hands on it.

Basically I want to be able to create some basic fun graphics behind an artist as he performs over a green screen. So I want to be able to key out the green screen, use multiple cameras and switch between them and also add the graphics from TouchDesigner all in realtime.

I have ATEM Television Studio Switcher which can take care of multiple cameras issue and can even do chroma key, if I have to do it there instead of inside TouchDesigner. What is the basic setup (including the nodes that I need to be familiar with) to be able to do this with the equipment that I have?

I will really appreciate any help.
