I haven't written a shader before, anyone have one they could share?
Or is this possible without shaders, i.e. just Gem objects?

I have done a lot of this type of processing with a shader. Just
pick the color in the desired range and set the alpha of a pixel in
that range to 0. After that just lay the video on top of each other.

I was wondering whether it is possible convert a specific color,
like green-screen chroma key, to alpha information using Gem. They
idea is to overlap many green-screen videos. I can see the pieces,
but I can't see the whole.
