DVD menus are important to provide information about the movie and allow the viewer 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 that matches the movie's tone, smooth transitions, appealing graphics and movement, visual effects for impact, and readable typography. Good examples are the Iron Man, Sin City, Italian Job, and Transformers menus which use animation, effects, film clips, and graphics to engage viewers.
