Mathias Möhl with a new script for After Effects called Expression Timeline which allows you to apply several expressions to a property so that each expression is active for only a certain period of time. How handy is that?! The script is available at AEscripts and also find out more information at Mamoworld.

“The ExpressionTimeline 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. Furthermore, you can specify time intervals in which no expression is active such that the keyframed motion is considered. The script can combine arbitrarily many expressions and works with whatever expressions you give to it.”
