# About

Flow gives After Effects an intuitive curve editor to adjust easings between keys. 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!

Developed by Zack Lovatt and renderTom, based on cubic-bezier.com by Lea Verou.

Bezier Graph

- Hold SHIFT to lock y-axis to nearest floor/ceiling
- Hold ALT to lock handle angle
- Hold CTRL to lock handle length
- Hold SHIFT+CTRL to move handles symmetrically

Default Library

Flow comes with 25 pre-defined, common curves for every day use.

User Library

Tired of the same-old quad and cubic curves? The User Library library lets you save your own curve shapes for easy access later. Double-click any item to immediately apply it:

- Hold SHIFT to apply with EASE IN
- Hold CTRL to apply with EASY EASE
- Hold ALT to apply with EASE OUT

Want to share your library or import an existing one? Use the Import / Export functions to spread your curves far and wide.

Bezier Values

Used to the web life? Flow works with the same webkit-transition-timing-functions you’ve come to know and love. Our values correspond directly to the values in cubic-bezier(0,0,1,1).

Apply as Expression

Don’t want to mess with your perfect keys? Instead, try applying your curve as an expression. Flow will apply the curve to each pair of keys.

Special thanks to Paul Conigliaro (@conigs ) for optimizing our expressions!
