The critical feature that sets After Effects apart is its sophisticated handling of Illustrator and Photoshop file imports. Both file types follow identical import workflows, offering three distinct approaches that professional animators must master.
Your first option imports files as flattened graphics—essentially treating them like JPEGs. While rarely ideal, this approach proves valuable when you need simplified assets or want to avoid layer complexity in your timeline. The second option allows selective layer extraction, perfect when you need just one element from a multi-layered source file. This targeted approach keeps your project lean and organized.
The third option—and the one we'll focus on—represents After Effects' true power. The software reads your source file comprehensively: analyzing layer structure, preserving positioning data, maintaining appearance settings, and converting everything into a native After Effects composition. Your imported comp mirrors the original layout exactly, complete with proper layer names and all applied settings intact. When importing Photoshop files specifically, you'll encounter an additional option for handling layer styles like drop shadows and bevels—choose whether to convert them to After Effects native styles or render them as static graphics.
Here's a crucial workflow consideration: theoretically, updating your source files should propagate changes to After Effects, though this dynamic linking primarily affects content rather than structural modifications. Understanding this relationship helps you plan your revision workflow effectively.
Before diving into the import process, we need to address a fundamental workflow challenge that trips up even experienced users. When After Effects imports Illustrator or Photoshop files as compositions, it inherits dimensional data from your source files—but static files lack temporal properties like duration, timecode, and frame rates. After Effects fills this gap by borrowing these settings from your most recently created or edited composition. This seemingly minor detail can create major headaches if your last comp was only 10 frames long, as extending composition duration after the fact proves surprisingly cumbersome.
The solution is elegantly simple: create a "dummy composition" before every import session. This throwaway comp serves one purpose—establishing your desired default settings for the incoming file. Think of it as calibrating your import environment to ensure consistent, predictable results across all your projects.
Beyond import mechanics, we'll tackle After Effects' most persistent organizational challenge. Unlike Photoshop's robust layer management system, After Effects offers limited organizational tools—no layer groups, no sophisticated filtering, just layer names, label colors, and basic solo/visibility controls. As your compositions grow more complex, effective layer organization becomes critical for maintaining both sanity and productivity. We'll explore practical strategies for managing increasingly crowded timelines.
Let's implement this workflow step-by-step. Starting with a fresh After Effects project, your first priority should be establishing proper file organization. Save your project immediately and create a centralized folder structure containing all media assets, project files, and eventual exports. While After Effects technically allows distributed file storage across multiple drives, this approach inevitably leads to missing media headaches and broken project links. Centralized organization pays dividends throughout your project lifecycle.
Now for the dummy composition setup. Navigate to Composition > New Composition and select any reasonable preset—the specific dimensions matter less since they'll be overridden by your import file. Focus instead on temporal settings: ensure square pixel aspect ratios (standard for all modern media), set appropriate frame rates for your delivery requirements, and establish reasonable duration defaults. Background color is irrelevant since imported layers will cover it entirely.
With your dummy comp created, you're ready for the actual import. Navigate to your source file but resist the urge to double-click immediately. Instead, verify your import settings: "Import As" should be set to "Composition," and "Retain Layer Sizes" must be checked. This latter setting proves crucial—it maintains each layer's content-based bounding box rather than forcing document-wide dimensions, resulting in more manageable and predictable layer behavior.
A critical warning: if After Effects detects sequentially numbered files (like "infographic_01," "infographic_02"), it automatically assumes you want to create an image sequence and will attempt to import them as video frames. Disable this "Image Sequence" option unless you specifically need this functionality.
Upon successful import, After Effects generates a composition folder containing your main comp plus individual layer assets. Double-click the composition (not the folder) to reveal your perfectly laid-out timeline. Every layer maintains its original position, naming, and appearance—no manual repositioning required. The folder contains individual layer elements for advanced manipulation, but the composition provides your primary working environment.
This import methodology works identically for both Illustrator and Photoshop files, though Photoshop imports offer additional layer style handling options. Master this workflow early—it forms the foundation for virtually every motion graphics project you'll tackle, and proper execution here prevents countless downstream complications.
