An AET file is best known as a template for Adobe After Effects, designed so you can open it repeatedly and save new versions rather than overwrite the source, with the file storing everything that defines the motion graphic: comps, timeline structure, layer stacks, animation keyframes, effect setups, expressions, cameras/lights, render settings, plus organizational items like folders and interpretation settings.

What an AET generally doesn’t hold is the full media; instead it stores links or paths to footage, images, and audio kept elsewhere, which explains why templates are often zipped with a Footage or assets folder and why missing-file prompts appear if media was omitted, plus the fact that AETs can depend on certain fonts or plugins means opening them on a different computer may cause font swaps until everything is installed, and since file extensions aren’t exclusive, verifying the file’s “Opens with” setting or checking its source location is the most reliable way to confirm its creator and needed companion files.

An AEP file is your ongoing After Effects project, while an AET is a reusable template, so in practice the difference lies in purpose: you open an AEP to continue that same project, but you open an AET to begin a new project instance so the original stays clean.

That’s why AET files are a go-to choice for motion-graphics template packs (intros, lower-thirds, slideshows): the designer keeps the AET untouched as the master, and you begin each new video by opening it and doing Save As to create your AEP before customizing text, logos, colors, and media, and although both AET and AEP contain the same technical elements—compositions, layers, keyframes, effects, expressions, cameras/lights, and settings—and both refer to external footage, the AET protects the template while the AEP serves as the editable, ongoing production file.

An AET file is meant to retain the structure and logic of a motion-graphics project but not necessarily its media, holding compositions with their resolution, FPS, duration, and nesting order, and keeping the full layer stack—text, shapes, solids, adjustments, precomps, and placeholders—plus each layer’s settings such as position, scale, rotation, opacity, masks, mattes, blending modes, and parenting, along with all animation info including keyframes, easing curves, markers, and any motion-driving expressions.

In addition, the template captures all effects and their configured values—whether color correction, blurs, glows, distortions, or transitions—plus any 3D setup involving cameras, lights, and 3D layer controls, along with render/preview preferences and project-level organization such as folders, labels, and interpretation rules, but it usually avoids bundling actual footage, audio, fonts, or plugins, relying instead on linked paths that can produce missing-asset or missing-effect warnings on another machine.
