Evan Abrams covers Interpolation Expressions, such as linear and ease, for modifying animation motion.

One of the fundamentals of creating animation is to modify the interpolation settings of motion. We know these as “ease” when speaking of animation. Check out this latest tutorial from Motion Designer Evan Abrams that covers working with Interpolation Expressions in After Effects from what are some of his most used scripting tricks.

“Some of my MOST used expressions in Adobe After Effects are the linear() and ease(), from the family of interpolation expressions,” Evan notes. “They help massage and manage data in your expressions, allowing more versatile connections between properties.” Once you get to know them, you’ll be using them all the time!
