# Easing

Easing in Premiere Pro is a little different than what we have implemented for After Effects. Limitations of Premiere's API force us to interpolate ease curves using a large number of additional keyframes, rather than just adjusting the speed and influence of two keyframes.&#x20;

* First, select a TrackItem that has two or more keyframes on one or more of its properties.
* The available properties to apply easings to will appear at the top of your Easing panel. You can only apply easings to one of these properties at a time.
* The keyframes that are on the selected property will also appear in your panel. By default, none of the keys are selected. This means that any easing in the panel will apply to **all** of the keyframes on that property.
* To apply easing to a subset of the total number of keys, click and drag the marquee selector in the Keyframe Timeline to select the keys you wish to ease

* Once selected, you can apply easing in a few different ways
  * Drag the Speed graph to adjust the speed curve
  * Adjust the Cubic Bezier graph handles in the Cubic display
  * Paste cubic bezier values in the Cubic display
  * Drag the influence or speed sliders
  * Apply an easing preset from an existing easing library

Once applied, you'll notice the interpolated keyframes added by Motion Studio:

In the panel, we don't show these additional keys, to keep things nice and clean:

To remove any keys added by Motion Studio, you can click the "Clean Keys" icon in the top-left corner

You can also apply **Auto-Bezier**, **Linear,** and **Hold** keyframe interpolation from the panel:
