1. START WITH A SPECIFIC VISUAL JOB
Paper animation works when the material changes the meaning of the shot. A fold can make a portrait feel like an introduction. A newspaper layout can turn a product image into a statement. A stack can give a group of photos a beginning and an ending. A tear can mark a before-and-after change.
Write the job in one sentence before choosing a template. For example: open on the finished portrait, fold the paper away, and leave the face full screen for half a second. That sentence gives you a start state, a transition, and an end hold. It also prevents the paper from becoming decoration that delays the important frame.
This sentence is useful when you compare tools, too. A preset that looks impressive in isolation can still be wrong for the edit if it hides the image for too long or ends without a usable hold. Treat the paper motion as a small shot with a beginning, a middle, and a final composition.
