Invert Motion
The Invert Motion option makes reversing keyframes in a single layer easy. This option allows you to easily change a zoom-in to zoom-out or switch a pan right to a pan left.
A simple example of Invert Motion is when you have a layer with two keyframes that you want to reverse. If the keyframes cause the layer to zoom in during the slide duration, using Invert Motion will make the layer zoom out instead. In this case, the first keyframe has a zoom value of 60, and the second keyframe has a zoom value of 80.
By right-clicking on either keyframe and selecting Invert Motion, the zoom value of 80 is applied to the first keyframe, and the zoom value of 60 is applied to the second keyframe.
This action makes the layer zoom out instead of zooming in.
When you have several keyframes with layer effects on a slide, using the Invert Motion option will change the order of the keyframes but won’t affect the layer effects or Motion Easing. Fly-ins will still be Fly-ins, and Fly-outs will still be Fly-outs.
If you intended a Fly-in to turn into a Fly-out or vice versa, change those options manually.
When changing the order of keyframes, you might need to reset any Motion Easing options, as well. When the keyframes became inverted, the keyframe that was originally at the beginning of the motion is now at the end. Motion Easing must be applied to the keyframe that starts motion, not the keyframe at the end, so be sure to reapply any Motion Easing settings to match the new keyframe placement.
