Nonlinear Animation is a more advanced method of animation. Unlike key framing, nonlinear animation is completely independent of time. You blend and layer animation sequences called clips, to set up the motion for objects. You can also use this method to explore variations in parts of the animation without losing your previous work or affecting other parts of the animation. For example-you can make the walking part of the animation a clip and then adjust the leg motion without affecting the way the rest of the character moves.
