To create a storyboard and animatic for a one-minute film trailer: 1. Visualize each key shot and scene using the provided storyboard template, discussing the camera movements and shot types. 2. Create an animatic in Adobe Premiere by cutting up an existing trailer to mark where shots change and determine the length of each shot. 3. Add up the number of storyboard frames needed to match the animatic, which will provide the structure for the original trailer.
