After Effects Expressions training

Learn Expressions in After EffectsAfter Effects logo

With expressions you can automate and simplify the workflow when working with animations, motion graphics and everything else in After Effects. You can work a lot faster, and more flexible, than if you only use keyframes. Expressions are especially useful when building MOGRTs – Motion Graphics Templates.

Pfeiffer did research for Adobe that shows that you can add graphics to a short video four times faster with Motion Graphics Templates!  Read the report here.

Expression code

Expressions are JavaScript based code

To work effectively with Motion Graphics in After Effects you need to know how to write expressions – code based on JavaScipt, with some special adaptations for After Effects. It sounds very hard to work with code, but but when you understand how these expressions are made, you’ll see that you don’t really have to write the code manually. After Effects can write most of the code for you!

Expressions can automate things that would take a long time to do manually

During this training you’ll earn how Expressions can be built faster and easier with point-ad-click, Expression Language Manus, and copy/paste from web sites and PDFs. You’ll learn what can be controlled with expressions – and what can’t be controlled with expressions. You’ll also learn how to build your own Expressions Library, to make re-using them a lot easier.

  • What are expressions?
  • Built-in Expression helpers in After Effects
  • Variables
  • Dimensions and Arrays, simplified
  • Expression Controls
  • Finding and fixing errors
  • Logical operators (if/else, and, or etc.) in combination with checkboxes, sliders, menus etc.
  • Treating text strings and splitting, changing and merge text
  • Time Expressions
  • Replacing keyframes with expressions
  • Rounding, maximum, minimum, PI and other JavaScript Math
  • Principles for building Motion Graphics projects with expressions
  • Exporting and sharing Motion Graphics Templates
  • Workshop


The first day of this two-day training is an intro to Expressions with lots of small projects. The second day is workshop based, where you build your own Motion Graphics projects with expressions. You can bring existing projects you want to streamline, or you can bring some Graphics elements (logos, fonts, still images and video, etc.) and start a new project.

When you’ve completed the two days, you’ll have one or more projects on your system with lots of useful expressions you can re-use in upcoming Motion Graphics projects in After Effects. You’ll also get an overview of the most used expressions for Motion Graphics, and a list of links to online resources like tutorials, forums, Facebook groups and blogs where you can learn more about expressions.


On-site training – or on Zoom/Teams

This is an on-site course, held at your companies’ premises. You must provide a room for the training, with a projector or big TV. Alternatively, it can be done online via Zoom or Teams.



You must know your OS (Windows eller MacOS) well, and manage to make folders, copy files, delete files, use keyboard shortcuts, etc. You must have the newest version of After Effects installed on your system. A free 7-day trial is OK.
