Information: - Vitaphone was a sound film system used for feature films and nearly 1,000 short subjects made by Warner Bros. and its sister studio First National from 1926 to 1931. Vitaphone was the last major analog sound-on-disc system and the only one which was widely used and commercially successful. The soundtrack was not printed on the film itself, but issued separately on phonograph records. The discs, recorded at rpm (a speed first used for this system) and typically in diameter, would be played on a turntable physically coupled to the projector motor while the film was being projected. Many early talkies, such as "The Jazz Singer" (1927), used the Vitaphone system. The name "Vitaphone" derived from the Latin and Greek words, respectively, for "living" and "sound". - A film genre (or ) is a motion picture category based on similarities in either the narrative elements or the emotional response to the film (namely, serious, comic, etc.). Most theories of film genre are borrowed from literary genre criticism. The basic genres include fiction and documentary, from which subgenres have emerged, such as docufiction and docudrama. Other subgenres include the courtroom and trial-focused drama known as the legal drama. Types of fiction which may seem unrelated can also be combined to form hybrid subgenres, such as the melding of horror and comedy in the "Evil Dead" films. Other popular combinations are the romantic comedy and the action comedy film. - A lost film is a feature or short film that is no longer known to exist in any studio archives, private collections, or public archives, such as the U.S. Library of Congress. - The Library of Congress ("LOC") is the research library that officially serves the United States Congress and is the "de facto" national library of the United States. It is the oldest federal cultural institution in the United States. The Library is housed in three buildings on Capitol Hill in Washington, D.C.; it also maintains the Packard Campus in Culpeper, Virginia, which houses the National Audio-Visual Conservation Center. - A feature film is a film (also called a movie, motion picture or just film) with a running time long enough to be considered the principal or sole film to fill a program. The notion of how long this should be has varied according to time and place. According to the Academy of Motion Picture Arts and Sciences, the American Film Institute, and the British Film Institute, a feature film runs for 40 minutes or longer, while the Screen Actors Guild states that it is 80 minutes or longer. - The musical film is a film genre in which songs sung by the characters are interwoven into the narrative, sometimes accompanied by dancing. - The term Sound-on-disc refers to a class of sound film processes using a phonograph or other disc to record or play back sound in sync with a motion picture. Early sound-on-disc systems used a mechanical interlock with the movie projector, while more recent systems use timecode. - Warner Bros. Entertainment Inc. (known professionally as Warner Bros. Pictures, often referred to as Warner Bros. and Warner Brothers and abbreviated as WB) is an American entertainment company, film studio and film distributor that is a division of Time Warner and is headquartered in Burbank, California. It is one of the "Big Six" major American film studios. - A sound film is a motion picture with synchronized sound, or sound technologically coupled to image, as opposed to a silent film. The first known public exhibition of projected sound films took place in Paris in 1900, but decades passed before sound motion pictures were made commercially practical. Reliable synchronization was difficult to achieve with the early sound-on-disc systems, and amplification and recording quality were also inadequate. Innovations in sound-on-film led to the first commercial screening of short motion pictures using the technology, which took place in 1923. - The Jazz Singer is a 1927 American musical film. The first feature-length motion picture with synchronized sound, its release heralded the commercial ascendance of sound films and the decline of the silent film era. Directed by Alan Crosland and produced by Warner Bros. with its Vitaphone sound-on-disc system, the film, featuring six songs performed by Al Jolson, is based on a play of the same name by Samson Raphaelson, adapted from one of his short stories "The Day of Atonement". - The phonograph is a device invented in 1877 for the mechanical recording and reproduction of sound. In its later forms it is also called a gramophone (as a trademark since 1887, as a generic name since c. 1900). The sound vibration waveforms are recorded as corresponding physical deviations of a spiral groove engraved, etched, incised, or impressed into the surface of a rotating cylinder or disc, called a "record". To recreate the sound, the surface is similarly rotated while a playback stylus traces the groove and is therefore vibrated by it, very faintly reproducing the recorded sound. In early acoustic phonographs, the stylus vibrated a diaphragm which produced sound waves which were coupled to the open air through a flaring horn, or directly to the listener's ears through stethoscope-type earphones. In later electric phonographs (also known as record players (since 1940s) or, most recently, turntables), the motions of the stylus are converted into an analogous electrical signal by a transducer, then converted back into sound by a loudspeaker. - Smiling Irish Eyes ( 1929 ) is a sound ( All - Talking ) American musical film with Technicolor sequences . The film is now considered a lost film . However , the Vitaphone discs still exist . - A short film is any film not long enough to be considered a feature film. Although no consensus exists as to where that boundary is drawn, the Academy of Motion Picture Arts and Sciences defines a short film as "an original motion picture that has a running time of 40 minutes or less, including all credits". The term featurette originally applied to a film longer than a short subject, but shorter than a standard feature film.
