Harry Frank returns with a new course focused on After Effects expressions programming. If you are new to the topic, or if you have some experience in the course topic, Harry will guide you from the basics into the heavy-duty code.

The structure of the course will use both conceptual lessons as well asl project-based lessons. Beginning with some basic math concepts, expressions and Javascript syntax, the course will build momentum and move into more advanced concepts such as world space, trigonometry, and understanding Javascript in more detail. You’ll gain tips and tricks that you’ll use in your daily workflow.

If you’re not using expressions, you should be! If you are…this course can take your knowledge to the next level.

Frank started in this business by studying classical percussion and audio engineering at the Fredonia School of Music in Fredonia, NY. After working the audio industry for a couple years, he slowly started to branch out into video editing and motion graphics in 1996. He’s worked as a freelance motion designer with clients such as, Blur Studio, Bl:nd, Digital Kitchen, NBC, and more. He’s currently a designer and product guru for Red Giant, where he produces content that helps animators and vfx artists better utilize their numerous software products.
