(Covers every link in AE animation, the most basic key frame principle, key frame type, and the most difficult part of curve adjustment in animation adjustment. Of course, there are some animation skills later, such as camera animation skills, how to make rich dynamics, etc. Here I share 7 small cases to explain and practice animation. Moreover, in order to improve efficiency, I also provide the drawn AE graphics files, so that everyone can start directly from the animation.)
