You know Captain Disillusion? "The World's Greatest Blenderer"? Well, he does this effect all the time in his videos; Adding videos on top of a board he's holding, to make it seem like he's holding one large, suspiciously bezel-less, screen.
Now, I'd like to emulate that in my video project. This MUST be a simple process, easier than adding a 3D object to a scene, since it's simply tracking a 2D plane and superimposing a 2D layer on top. But I just can't figure out HOW I would look this up! "Chroma keying" just turns up tutorials of how to remove backgrounds from videos (Done that before), and other keywords didn't help.
So, how can I do this? And, do I need a green board for this, or would a white board with dots on it be better? And importantly, how would I go about masking the video (to compensate for fingers, etc)? Would it be better to use Adobe After Effects, since I have that in hand?
Thank you guys for the help! It would be amazing to be able to make this effect work.
