Flash CS4 has a number of pre-made motion tweens ready for you to use. In this recipe, you will apply motion presets to symbol instances.
Have a file open that contains a movie clip symbol instance. If you do not have such a file, make a new file in Flash, create a shape or import a file, and then go to Modify | Convert to Symbol. Name the symbol, choose movie clip for Type, and hit OK. You are ready to roll.
1. Go to Window | Motion Presets to get the Motion Presets panel if it is not already open.
2. Double-click on the Default Presets folder to gain access to the presets.
3. Select your symbol instance by clicking on it with the Selection tool.
4. Click on a preset, such as fly-in-blur-left and click Apply.
5. Save and test your movie (Ctrl/Cmd Return).
