Keyframe several different expressions on one property
The Expression Timeline allows you to apply several expressions to a property such that each expression is active only for a certain period of time. Instead of an abrupt change between the expressions you can also smoothly transition from one expression to the next.
In this tutorial we create a transition from one text to another one that reuses as many letters as possible from the first text in the second one. Only where it cannot be avoided, letters are deleted or new ones inserted.
