With animation presets, you can save and reuse specific configurations of layer properties and animations, including keyframes, effects, and expressions. For example, if you created an explosion using several effects with complex property settings, keyframes, and expressions, you can save all of those settings as a single animation preset. You can then apply that animation preset to any other layer.
Many animation presets don’t contain animation; rather, they contain combinations of effects, transform properties, and so on. A behavior animation preset uses expressions instead of keyframes to animate layer properties.
Animation presets can be saved and transferred from one computer to another. The filename extension for an animation preset is .ffx.
After Effects includes hundreds of animation presets that you can apply to your layers and modify to suit your needs, including many text animation presets. (See Text animation presets.)
You can browse and apply animation presets in After Effects using the Effects & Presets panel or Adobe Bridge. To open the Presets folder in Adobe Bridge, choose Browse Presets from the Effects & Presets panel menu or from the Animation menu.
