Sub-Frame Motion Blur
You can activate Sub-Frame Motion Blur (SFMB) to simulate a camera panning swiftly.
With a real-life camera, motion blur arises when an object flies past the camera at great speed or when the camera pans rapidly (Sub-Frame Motion Blur). This motion blur helps to create the illusion of real motion rather than a sequence of still pictures and so it is of great use to animation software. Animation software does not use real shutters and real film, so the motion blur must be faked, see Figure 1, below.
