What is letterboxing?

It’s a practice of transferring film shot in the widescreen aspect ratio to standard-width video formats while preserving the film’s original aspect ratio. The image has black bars above and below it a.k.a mattes.

Mattes are required to combine two or more image elements into a single, final image or it’s used to mask certain areas of film emulsion to selectively control which areas are exposed.

There’s static matte, where the shape of the mask doesn’t change from frame to frame. Other shots may require mattes that change, to mask the shapes of moving objects, such as human beings or spaceships. These are traveling mattes. They enable greater freedom of composition and movement.
