Weird camera behaviour when given offset

Hi there! I am currently in very early development stage of a game, and I am trying to get a camera system a bit like in Dawn Of Aurora’s. I have tried setting the humanoid’s CameraOffset to 1,0,0, but when you turn using the A and D key’s, the camera goes a bit weird, and looks strange.

Here is a video of my camera system:

And here is a video of Dawn Of Aurora’s:

I noticed that their camera mode and movement mode has been set by the developers, so this could be something, but when I flick through the options in my game, nothing changes.

Any help is much appreciated!
