Chapter 10. Adding Effects > Understanding Properties and Animation

Understanding Properties and Animation

A property refers to any effect parameter to which you can assign a value. For example, you can specify a clip’s Opacity property value from 0 percent (completely transparent) to 100 percent (completely opaque), or you can determine the intensity of the Gaussian Blur filter by adjusting its Blur value. You can set any property to a global value, a single value for the duration of the clip. You can also animate a property, varying its values over time.

To produce animation, you change a clip’s properties over time—for example, you create motion by changing a clip’s position over time. In Premiere Elements (as in other programs), you use keyframes to define and control these changes.
