Now, using expressions in After Effects is an entire study by itself, let alone how to use them in this one instance. If you're in need of a continuous background, or are creating a flat, two-dimensional animation that doesn't travel along the z-axis, this tutorial is pretty cut and dry and gives you the exact answers you're going to need in order to create it. There are several methods to achieve this, but Borup utilizes a semi-simple layering process in After Effects that slides each layer at different speeds across the frame. Essentially what this does is gives the illusion of depth using the parallax effect. Parallax scrolling is used a lot in video games, but can also be used in animation and other media. Mikey Borup shares a tutorial that makes parallax scrolling a little bit easier. Selecting a region changes the language and/or content on I first started dabbling in After Effects and Flash several years ago, the first videos I made were simple animations (think cave drawings.) Not really knowing anything about layers or expressions made for interesting results when I tried to achieve the parallax effect - the illusion that objects move more quickly or slowly depending on how far away they are. Here's a basic example of looping with expressions: If you want to know more about it, see Understanding the Expressions language. You can create expressions by using the pick whip or by copying simple examples and modifying them to suit your needs. The expressions language is based on the standard JavaScript language, but you do not need to know JavaScript to get started with expressions. Rather than animating the Position property with keyframes, you can apply a wiggle expression to it. For example, you have a ball moving across the screen from left to right, but you also want that ball to wiggle. Unlike a script, which tells the application to do something, an expression tells a property to do something. When you want to create and link complex animations, but want to avoid creating tens or hundreds of keyframes by hand, try using expressions. An expression is small piece of JavaScript code that you can plug into animated properties in your After Effects projects, that evaluate to a single value for a single layer property at a specific point in time.
