Animation presets can be applied to their originating comp or at any point in the future. That's because the presets are actually stored to a separate file on your hard drive (much like Photoshop Actions).
If you save animation presets in the Favorites folder, they'll appear in the Effects & Presets Window.
Be sure to back up your presets folder or a reinstall could blow away all of your custom work.
All previous favorites from earlier versions are promoted to animation presets.
To create and save an animation preset:
Choose the properties, property group , or effects (or any combo of these) that you want to keep and reuse.
Choose Animation>Save Animation Preset or click the Save Animation button in the Effects & Presets palette.
Give your preset a descriptive name and then add the extension .ffx
Place the preset into the Favorite folder and if you'd like you can create subfolders to organize your effects. These subfolders will show up in the Effects & Presets palette.
