Others uses of colored mattes appear in ads from Allstate, Aleve, and Kodak among others, and in music videos such as Zebraheads, " Playmate of the Year". IBM has used blue mattes for many of their TV ads, yellow mattes in their "I am Superman" Lotus ads, and green mattes in ads about efficiency & environmental sustainability. Letterbox mattes are not necessarily black. Usually, such matting of 1.85:1 film is eliminated to match the 1.78:1 aspect ratio in the image transference. Because the 1.85:1 aspect ratio does not match the 1.78:1 aspect ratio of widescreen video, slight letter-boxing occurs. On a widescreen television set, a 1.78:1 image fills the screen however, 21:9 aspect ratio films are letter-boxed with narrow mattes. In addition to films produced for the cinema, some television programming is produced in high definition and therefore widescreen. Ĭurrent high-definition television systems use video displays with a wider aspect ratio than older television sets, making it easier to accurately display widescreen films. In addition, recent years have seen an increase of "fake" 2.40:1 letterbox mattes on television to give the impression of a cinema film, often seen in adverts, trailers or tv such as Top Gear. When using a 1.33:1 screen, it is possible to display such programming in either a letter-boxing format or in a 1.33:1 center-cut format (where the edges of the picture are lost).Ī letter-boxed 1.56:1 compromise ratio was often broadcast in analogue transmissions in European countries making the transition from 1.33:1 to 1.78:1. Most television channels in Europe are broadcasting standard-definition programming in 1.78:1, while in the USA, these are down-scaled to letterbox. On television ĭigital broadcasting allows 1.78:1 widescreen format transmissions without losing resolution, and thus widescreen is the television norm. The image is produced by using a map projection-like technique to approximate how the picture might look if projected onto a curved Cinerama screen. The term "SmileBox" is a registered trademark used to describe a type of letter-boxing for Cinerama films, such as on the Blu-ray release of How the West Was Won. When HIT Entertainment in North America released the Wiggles’s “Cold Spaghetti Western” video in the beginning of this century, it was presented in 1.78:1 widescreen but in 1.33:1 letter-boxing format to accommodate full-screen TV's, which were still fairly common at the time of its release in the United States and Canada. Each disc contains a label noting the use of "RCA's innovative wide-screen mastering technique." In cinema and home video The first fully letter-boxed CED release was Amarcord in the past century, and several others followed including The Long Goodbye, Monty Python and the Holy Grail and The King of Hearts. Initially, letter-boxing was limited to several key sequences of a film such as opening and closing credits, but was later used for entire films. The first use of letter-boxing in consumer video appeared with the RCA Capacitance Electronic Disc (CED) videodisc format. The term refers to the shape of a letter-box, a slot in a wall or door through which mail is delivered, being rectangular and wider than it is high. The resulting video-graphic image has mattes empty space above and below it these mattes are part of each frame of the video signal. Letter-boxing is the practice of transferring film shot in a widescreen aspect ratio to standard-width video formats while preserving the film's original aspect ratio.
