Flow brings an easy interface to After Effects for customizing animation curves, without needing to venture into the aging, confusing graph editor. Gone are the days of slow, heavy expressions, or fighting with speed and influence (what do those even mean?) – just make a curve, hit APPLY and you’re gold!

Used to the web life? Flow works with the same CSS animation-timing-functions you’ve come to know and love. Our values correspond directly to the values in cubic-bezier (x1,y1,x2,y2). Flow’s core is based on Lea Verou’s cubic-bezier, so you are free to copy URL values and paste them into the extension – Flow will parse them and apply the exact same transition to your selected keyframes or expression.

Flow comes with 25 pre-defined, commonly-used motion curves based on Robert Penner’s Easing Functions. But don’t limit yourself – build your own library and share it with the world, or import custom presets from other animators with the single click of a button.
