I know how the green/blue screen process works, keying, tracker markers e.t.c. But I noticed in a music video I watched today that the focus changed through a shot, and the false digital background also changed focus.
Is it just a case of constantly digitally matching the focus of the background with everything else? Or is there something else involved that I've missed out? Focus, marker? Just kidding.
