To enable linear blending
Linear blending emulates the combination of colors in a way that more accurately reflects how colors blend in real
life. For example, it corrects dark halos and fringing when high-contrast, saturated colors are blended together. If
linear blending isn’t enabled, RGB colors are blended in the project working color space, which in some cases can
result in edge or halo artifacts. When you enable linear blending, After Effects blends RGB colors in a color space
with a gamma of 1.0, which is considered colorimetrically correct and results in the fewest artifacts. Linear blending
affects layer, text, paint, and 3D blending.
To see the dramatic effects linear blending can produce, try painting with a soft green brush on a red solid and then
applying linear blending.
Compositions render more slowly when linear blending is enabled, so enable it only if necessary.
❖ Choose File > Project Settings, and choose Linear Blending.
Plug-ins and scripts
Plug-ins
Plug-ins are small software programs that work with another program to add functionality. A number of plug-ins
come with After Effects and are automatically installed in folders inside the Adobe After Effects 7.0 folder. You can
otain other plug-ins for After Effects from Adobe or third-party vendors.
Many third-party effects are available in the form of plug-ins. Some plug-ins can also speed rendering and perform
such tasks as format conversion.
You can find information about third-party plug-ins available for After Effects in the Support area of the Adobe
website.
For plug-ins to work with After Effects, they must be in the Plug-ins folder, which is in the Adobe After Effects
7.0\Support Files (Windows) or Adobe After Effects 7.0 (Mac OS) folder by default. For specific instructions about
installing a plug-in, refer to its documentation.
Note: (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.

Scripts (Pro only)
A script is a series of commands that tells your computer to perform a sequence of operations. You can use scripts
to automate many tasks in After Effects Professional. For example, you can direct After Effects to import multiple
footage files.
