Plug-ins are small software modules—with filename extensions such as .aex, .pbk, .pbg, and .8bi—that add functionality to an application. Effects in After Effects are implemented as plug-ins, as are some features for importing and working with certain file formats. The Photoshop Camera Raw plug-in, for example, provides After Effects with its ability to work with Camera Raw files.

Install and load plug-ins

You can obtain plug-ins for After Effects and other Adobe products from Adobe or other vendors. For specific instructions for installing a plug-in, see its documentation.

When After Effects starts, it loads plug-ins from several folder, including the Plug-ins folder. If a plug-in doesn’t come with an installer or with specific instructions for its installation, then you can usually install the plug-in by placing it in the Plug-ins folder.

By default, the Plug-ins folder is in the following location:

  • (Windows) Program Files\Adobe\Adobe After Effects <version>\Support Files

  • (Mac OS) Applications/Adobe After Effects <version>

Several plug-ins come with After Effects and are automatically installed in the Plug-ins folder.


When loading plug-ins, After Effects ignores the contents of folders with names that begin and end in parentheses; for example, the contents of the folder (archived_effects) are not loaded.

After Effects also loads plug-ins from a MediaCore folder, which is intended to hold plug-ins shared between After Effects and Premiere Pro. Some third-party plug-in installers install their plug-ins in this folder. In general, unless specifically instructed to do so, don’t install plug-ins in the MediaCore folder. If you install a plug-in in this folder that is not supported by one or more of the applications that read from this folder, you may encounter errors or other problems.


(Mac OS) Some third-party plug-in installers incorrectly install their plug-ins into the Mac OS X Package for After Effects. To reveal these plug-ins, Control-click the After Effects application icon in the Finder and choose Show Package Contents. You can then move the plug-ins into the After Effects Plug-ins folder.

When exchanging After Effects projects between computer systems, make sure that the plug-ins that the project depends on are installed on both systems. Similarly, if you're rendering a composition with multiple computers on a network, make sure that all plug-ins used in the composition are installed on all rendering computers.


On Mac OS, press Command+Option+Shift+Help to generate a list of all plug-ins loaded into After Effects (including version numbers). For information on using this command on Windows or with a Macintosh keyboard that doesn't have a Help button, see Todd Kopriva’s blog on the Adobe website.
