<p>In After Effects, the keyframe ease, which actually controls the Bézier interpolation between keyframes, consists in two values:</p>
<ul>
<li>The <strong>influence</strong> controls what would be the length of the tangent of the Bézier curve in the graph editor; for horizontal tangents (i.e. with <code>0</code> velocity), it directly controls the acceleration (ease out) and deceleration (ease in) of the motion around the keyframe.</li>
<li>The <strong>velocity</strong> is a signed
