YOu can fiddle with computer models in morphing to produce this
effect. Instead of having a constant rate of change you can
speed it up for a short time and then slow it down. If you look
at the frames during the speeded-up set of frames, you will, of
course, find them to be 'gradual'. How could it 'jump'?
