[HELP] Camera in a square

[..:D&G:..]

Hello, I joined FFS recently and I saw their lobby. I wanted to ask you guys, how can I do like them, when you hit F1, the camera is in a small square, not on the whole screen.

The camera/view of the game would be in one of those boxes. How can I do that?

There's more stuff involved such as animations thought.
