A successful motion path has two components: geometry and timing. The geometry is created by choosing keyframes. The timing of the path is more complex, and can be affected by the geometry.

Intuitively, the timing of a path is simply the speed of motion of the object as it moves along the path. Since PictureMaker starts with keyframes and creates in-between positions, PictureMaker determines the velocity by deciding how many in-betweens to place between each keyframe (and where to place them). Several methods can be used to determine velocity along the path. a) Place frame evenly between all keyframes. Closely placed keyframes will correspond with slow moving parts of the path.

b) Specify a relative velocity at selected keyframes, and specify correspondences between any keyframe and a frame in the final animation.
