Ingame Recording

So i suck at making cinematics and this idea came into mind.What if the Game has Ingame Recording?I intended my Idea to record ingame sounds only (of course)
I think that this should came into two categories:

1.)Cinematic Recording-Being able to record your gameplay and you see the Gui around your screen but does not show the gui when recorded.This Category was intended for Flight only where you can fond it easily somewhere in the screen.

2.)Game Display Recording-Will record everything that you can see ingame.This Category is intended for the Menu,Loading Screen,Designer and Inflight.

Questions will be answered down below :)
