JR 6245: 1st Idea

If we are filming in such an area like woodland for example, we could have a swish pan representing the movement of a character in a frantic, panicy manor. With this the camera quickly swishes around and a figure can just be seen in the distance but then goes out of picture because of the pace of the swish. The camera then swishes back, as if to represent the character noticed the figure, but the figure, at a second look, is gone.
