DVD menus are important to provide viewers with information about the movie and allow them to change settings like language. Motion graphics and compositing enhance menus by keeping viewers engaged until the movie starts. Effective menu design considers the target audience, color combination suited to the film's tone, smooth transitions, appealing graphics and movement, visual effects, and readable typography. Good menus displayed elements like scenes from the film, animation, visual effects and transitions as shown in examples from Iron Man, Sin City, The Italian Job, and Transformers.
