What are Story Groups?
Story Groups are story-related containers in the library, like shows, scenes, or shots. Shows contain scenes, scenes contain shots, and shots contain video/audio clips. They can also hold anything related to that group, like pictures or pdfs. Plus, they are also timelines where you can assemble your movie. See Growing a Story in the Pretend User Guide to learn more.
