In this tutorial, you'll learn about Adobe's new feature called Protected Regions or Responsive Regions. This feature allows you to retime animations without having to manually stretch or shrink them. It also allows for changes to be made to the animation without having to duplicate the layer or adjust the composition settings. This feature can save a lot of time and frustration when editing a lengthy documentary or making multiple changes to a low third.
