Letterboxing (video) is the practice of transferring video shot in a widescreen aspect ratio (16:9) to standard-width video formats (4:3) while preserving the video’s original aspect ratio. The resulting videographic image has mattes (black bars) above and below it; these mattes are part of the image (i.e., of each frame of the video signal).
Letterboxing was developed for use in 4:3 television displays before widescreen television screens were available.
Letterbox mattes are usually symmetrical (both the top and bottom mattes are roughly similar in size), but in some instances the picture can be elevated so the bottom matte is much larger, usually for the purpose of placing "hard" subtitles within the matte to avoid overlapping of the image.
