This video will cover how to handle objects moving around the frame - specifically transitions between keyframes using easing functions. When animating objects, easing is used to make motion look more natural.

A linear motion with an instantaneous start and stop appears artificial; adding smooth start and stop, acceleration, or “bounce” effects can remedy this. To demonstrate, we’ll create a logo drop like you see here. We’ll begin with the object out of the frame and set the first keyframe. Then we’ll move our play head forward several seconds and move the object into the center of the frame and set another keyframe. Now, you can see that the logo drops slowly into the second position over time.

To apply an easing function, right click on the timeline between the two keyframes you’ve created. There are a range of pre-defined actions from which to choose. We’ll go with “Out Elastic” to create a bounce effect. You can see that effect here.

All easing functions can be customized, so users are in complete control over how to animate objects around the frame.

In the next video we’ll go over easing functions in more detail and demonstrate a few of the pre-defined options.
