Apply custom ease in/ease out to motion tweens
The Custom Ease In/Ease Out dialog box displays a graph representing the degree of motion over time. The
horizontal axis represents frames, and the vertical axis represents percentage of change. The first keyframe is repre-
sented as 0%, and the last keyframe is represented as 100%.
The slope of the graph's curve represents the rate of change of the object. When the curve is horizontal (no slope),
the velocity is zero; when the curve is vertical, an instantaneous rate of change occurs.
