Presets provide a quick, easy way to apply common animation effects. (See <a href="1_7_3_1.html">Applying preset effects</a>.) For more precise and complex animation, manually create keyframes.</p><p class="paragraph">When you create a keyframe, you specify the value of an effect property for a specific point in time. When you apply different values to keyframes, Adobe Premiere Elements automatically calculates the values between the keyframes, a process called <span class="Emphasis">interpolation</span>. For example, to add a blur effect that increases and decreases over time, you would set three keyframes--the first with no blur, the second with blur, and the third with no blur. Because Adobe Premiere Elements automatically interpolates the blur values between each keyframe, the blur gradually increases between the first and second keyframes and then gradually decreases between the second and third keyframes.</p><p class="paragraph">Animating with keyframes involves the following basic steps:</p><li class="numberstep" type="1" value="1">Apply an effect to a clip.
