Motion graphics are video animations consisting of moving designs, illustrations, and images used in multimedia projects. They are usually created using software and combined with audio. Saul Bass was a pioneer in motion graphics who created title sequences for films. His 1959 sequence for the film Anatomy of a Murder featured a dismembered body that was revealed piece by piece with crew members' names, symbolizing the mystery of the murder plot. Matte paintings, CGI, chroma key, and other visual effects techniques help create realistic backgrounds and environments not present on set.
