What's Flow?
Flow gives After Effects an intuitive curve editor to adjust keyframe easing.
Gone are the days of fighting with speed & influence (what do those even mean?!), or navigating through some bloated 8000-features-in-one garbage pile to find their easing system – just make a curve, hit Apply and you're gold!
Flow is a collaboration between Zack Lovatt and renderTom.
Flow Features
Flow consists of two main components: the Graph Editor and the Library.
The graph editor is all about easing – lose AE's internal graph editor in favour of a modern, snappier, normalized environment.
The library is all about presets – have you come up with some on-brand, snappy easing curves? Have a go-to animation style and want to bring it everywhere you go? Save your curve as a preset, and build out your own custom easing libraries.
Beyond the basics, Flow lets you:
- share your library with others,
- apply curves as expressions,
- quickly copy or paste your curve as cubic bezier values,
- ditch Flow's UI altogether by exporting your library to KBar,
- and more!
New: Flow v1.5 introduces multi-library support, responsive overshoot & undershoot of graph values, dynamic controls location, kbar export, and much more!.
For further information on how to use Flow & what it can help you accomplish, check out our user guide.
