Hey There Total_warrior,
I see that you posted some questions concerning cinematics. There is allot to it.
Angle wise is just experimenting, look at other cinematics to get ideas (or look at movies, and watch the camera angles closely).
In regards to smooth camera movement (panning) you can use a camera system created by Anitarf. (

If you are looking more simplistic stuff, have a look in my map `Darkness Within´ and look for systems "Camera"
It's something I made quite a while back, but it does the job (somewhat).
If you have more questions, feel free to ask.
Good luck on your project
