ABSTRACT
This chapter focuses on creating complex animations that are easy to edit. It includes many examples showing the benefits of nesting two dimension comps. The chapter covers Precomposing. Nesting a comp not only allows for animating multiple layers as a group, it is also a convenient way to apply an effect to a group of layers at once. A comp that is nested inside another comp is often referred to as a precomp, or intermediate comp, indicating that it is not the final output comp. Nested comps can also help to manage a sequence of video clips. The Composition Navigator is a new user interface element that has been added to the top of the Composition panel. Preserve Frame Rate is particularly useful to “lock” animation keyframes to a movie’s frame rate. Collapsing transformations and continuous rasterization rewires the rendering order.
