Videos on TVs and Projectors

I’ve seen videos played on TVs and projectors in Gmod, and other source games. I thought they were just edited in, but they match the screen size perfectly. How do they do it? Some of it, or all, maybe fancy editing, I don’t know.


Greenscreen and/or video editing.



Figured. Thanks.
