What It Does
The Power of Expression is a book written for After Effects users who want to learn expressions from the ground up. Author François Lefebvre designed it as both a complete course and a daily reference, covering everything from basic syntax to advanced techniques. Available as a hardcover or eBook PDF.
Key Features
Complete expression course. The book assumes no prior coding knowledge and teaches the entire expression language step by step. You’ll learn values, objects, methods, keywords, and syntax rules.
Structured reference format. Since expressions are written code, learning through reading makes more sense than video tutorials. You can quickly search for specific terms and review concepts as needed.
Practical focus. The book explains how expressions work in real After Effects projects, covering linking properties, automation workflows, and maintaining consistency across collaborative work.
Table of contents includes: values and how to apply them, object hierarchy and how to call values, methods and arguments, syntax rules (case sensitivity, comments, statements), keywords like var and if/else, and mathematics with arithmetic operators.
Sample chapter available. A preview PDF shows the book’s layout and teaching style, covering topics like reaching After Effects’ full potential and François Lefebvre’s minimalist approach.
Who It’s For
Motion designers and editors at any skill level. If you’ve avoided expressions because they seem intimidating, this book breaks them down into logical, approachable pieces. If you already use expressions, it serves as a reference to clarify concepts and clean up your code.
Useful for teams who need consistent, maintainable project files. Expressions make templates easier to edit and share across multiple artists.
