mask green matte for VFX?

Hi I’m in movie industry and my studio would like to use UE4 as previz.

we would like to sync 3d BG with real green matte BG like video clip in following link.

I have 0 idea how to start and there's no keyword I can find. what kind of camera should we use and what kind of hardware or plugin or skill should I learn in UE4?

keywords “mixed reality” and “Augmented Reality” should turn up a few things.

I think some folks do it by attaching a vr motion tracker to the camera, so “vr” is probably a keyword too.

also “ue4 media framework” since you would probably need to figure out how to stream your camera into the material.
