In Adobe Premiere Elements, you can create three types of Bezier interpolation: Bezier, Auto Bezier, and Continuous Bezier.</p><p class="run-inhead">Bezier interpolation</p><p class="paragraph">Provides the most precise control because you manually adjust the shape of the path segments on either side of the keyframe. Unlike other interpolation methods, the two direction handles on a Bezier keyframe operate independently so you can create a curving motion path that suddenly turns into a corner. This interpolation method is ideal for drawing a motion path that follows a complex shape.</p><p class="paragraph">If you apply Bezier interpolation to the keyframe of an effect property, Adobe Premiere Elements creates a smooth transition on both sides of the keyframe. The initial position of the direction handles is calculated using the same method used in Auto Bezier interpolation.</p><p class="run-inhead">Auto Bezier interpolation</p><p class="paragraph">Creates a smooth rate of change through a keyframe. You might use Auto Bezier spatial interpolation to create the motion of a car turning on a curving road.</p><p class="paragraph">As you change an Auto Bezier keyframe value, the positions of the direction handles change automatically to maintain a smooth transition between keyframes. These adjustments change the shape of the segments on both sides of the keyframe. If the previous and next keyframes also use Auto Bezier interpolation, the shape of the segments on the far side of the previous or next keyframe also changes. If you adjust an Auto Bezier direction handle manually, you convert it to a Continuous Bezier keyframe.</p><p class="run-inhead">Continuous Bezier interpolation</p><p class="paragraph">Like Auto Bezier interpolation, Continuous Bezier interpolation creates a smooth rate of change through a keyframe. However, you set the positions of Continuous Bezier direction handles manually. Adjustments change the shape of segments on either side of the keyframe. If you apply Continuous Bezier interpolation to all keyframes of a property, the values at each keyframe are adjusted to create smooth transitions. Smooth transitions are maintained as you move a Continuous Bezier keyframe.</p></ol><hr /><div class="breadcrumbs"><a href="1_8_8_2.html" title="About spatial and temporal interpolation">Previous</a> | <a href="1_8_8_4.html" title="Adjusting Bezier keyframe interpolation">Next</a> | <a href="#top">Top</a> | <a href="1_8_0_0.html">Animating Effects</a> > <a href="1_8_8_0.html">Controlling the smoothness of animation</a></div></td></tr></table>
