Most of the angles I use are f5 and f2 in cinematic mode (f9).
Reason: Reverse Camera Angle shows the target camera facing your ship, keeping both in view. F5 does the opposite, camera shows your ship and the camera is facing the target. I also use f2, this way, I can simulate a fleet of ships moving. In reality, that fleet isn't moving at all, the invisible camera is.
The camera moves so smoothly because when I use the s-video out on my video card, I use a video capture card on my other computer to record and it records with mpeg. I don't have to set my AA as high since mpeg smoothens it out during recording. Sometimes, speeding up the video 2x helps but 4x shows all the little adjustments in turning very well.
