What are the benefits of using Motion Control?
By programming the motion of the camera and changes in zoom and focus of its lens, a complex and fluid camera movement can be achieved. Further sophistication can be added by synchronising camera motion with lighting changes and movements of props. Such sophistication would be very difficult to achieve manually.
In addition, many post-production special effects are achieved by filming the same sequence several times, with the camera movements being identical each time. For example, if the scene were changed to represent the four Seasons of the year before each of four takes, a composite sequence can be assembled easily in post-production by mixing from one take to another, thus giving the impression of the changing Seasons as the camera moved.
Finally, by utilising the data that controlled the motion of the camera during a sequence, it is possible to combine live action shots taken in the real world with computer generated images ('CGI') of either environments or objects. Typically this would be achieved by shooting props against a blue screen, which allows the prop to be isolated from its environment during post-production and combined with computer generated elements.
