Chroma keys are not just for weather reports but to set up interesting interview backgrounds for podcasts and other online events. If you set up a different chroma key, say one for each of your three cameras, you can create the illusion that you are cutting around a virtual set.
Another use for this type of Key might be for putting lyrics on a stream. If you connect a graphics source, such as Propresenter, and put white text over a green colored background you can have the switcher remove the green color and layer the text over your video. Another great thing about using a chroma key is that it allows you to keep a thin outline, such as a black line around white text, for easy readability.
