Scriptable camera type won't work properly?

I'm making a camera animation script that does stuff when you jump and land etc But whenever you change camera type to scriptable it won't focus on anything, or you can't change CameraSubject, so it just stays there fixed in one position. How would you do this?

Camera's subject is what the camera is attached to. (Normaly the player's head) Camera's focus is what the camera is looking at. (Normaly the player's head too) Scriptable type is like if you had a anchored camera. Cannot move.

If you need the camera to stay in a position and always look to the player, try the Watch type.

Tell me what you actually need.
