Film Language Tag: multi-image screen
An optical or digital effect where two or more separate images appear within the same frame at the same time, as with The Birth of a Nation (1915) or More American Graffiti (1979), or on separate screens, as with Napoléon (1927). The most common form is the split screen, with two images side by side.
USAGE: Since Cinerama and similar processes project a single image onto multiple screens, they are not considered multi-image formats.
