Build Better Rigs: Slider Controls and the Wiggle Expression

Expressions in After Effects can feel like learning a second language just to move a single layer. In this video, we're breaking down expression controls—the simple sliders and checkboxes that turn a messy timeline into a professional workflow.

We'll start by building a custom control panel for everyone's favorite expression: the Wiggle. By adding slider controls directly to your layers, you can easily animate and adjust your wiggle frequency and amplitude (or speed and strength) without diving back into the code every time.

What you’ll learn in this tutorial:
• Why expression sliders are essential for building better rigs.
• How to rename and organize your sliders for a clearer workflow.
• Using the pick whip to link your wiggle expression to custom sliders.
• The secret to animating expressions over time using keyframes on your sliders.

Whether you’re a beginner or looking to streamline your professional workflow, this first video in our series will help you master the power of After Effects expression controls.
