ABSTRACT
This chapter explores how to improve the animations by focusing on the timing and speed changes of the movements. It shows a few quick tricks, and focuses on the Graph Editor: an industrial-strength tool for refining the animations. The chapter provides the keyframe velocity tour with roving and hold keyframes. Keyframed values in the timeline default to linear interpolation. This means the values they are assigned to – rotation, scale, effect parameters, and such – change by a constant amount from frame to frame in-between keyframes. An important feature of the Graph Editor is its ability to superimpose multiple values on the same graph, making it easier to coordinate multiple properties. Position keyframes are a special case with the Graph Editor. A single Position keyframe contains multiple parameters: X Position, Y Position, and in the case of a 3D Layer, Z Position. Adjusting the timing of a single Position keyframe affects all of the XYZ values together.
