Modify Transform properties

You can create more efficient animations by modifying Transform properties and avoiding Layer and Object Attribute properties. For example, using the Transform Scale property to change an object's width results in a smaller file size than using the Width property in the Layer palette (which changes the object to a bitmap when exported). Transform attributes are located on the Transform palette, Object Opacity on the Opacity palette, as the Object > Transform > Flip Horizontal and Flip Vertical commands, and within an object's Transform properties in the composition's Timeline window. You can also animate any of these transform properties from the Timeline window.
