Morph Source

The morph source function gives you the capability of morphing two shapes that are not currently morphing. This is particularly useful if you insert a movie into your current movie and you want to cause morphing between shapes in the current movie and those in the inserted movie. Each shape can have only one morph source. The morph source dialog asks you to select a shape from the previous key frame to assign as the morph source to a selected shape in the current key frame.
