Go-Motion

Go- Motion is an animation technique that emerged in the early 1980s and is a modification of the stop-motion technique.

In stop-motion animation objects are animated by being changed slightly for each new image; while a setting is photographed for each image in the film. The final sequence, however, it loses its natural motion blur, making the animation may appear jerky when playing the movie.

To produce the necessary effect of focus, therefore, the objects to be moved by computer-controlled motors, while the camera shutter is open during the Go -motion. So the moving parts seem to naturally slightly blurred.
