Question: Information: - 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. - 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". - Footlights and Fools ( 1929 ) is a sound film billed by Warner Brothers as an all - talking musical film , released in Vitaphone with Technicolor sequences . - 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 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". - A silent film is a film with no synchronized recorded sound, especially with no spoken dialogue. The silent film era lasted from 1895 to 1936. In silent films for entertainment, the dialogue is transmitted through muted gestures, mime and title cards which contain a written indication of the plot or key dialogue. The idea of combining motion pictures with recorded sound is nearly as old as film itself, but because of the technical challenges involved, synchronized dialogue was only made practical in the late 1920s with the perfection of the Audion amplifier tube and the introduction of the Vitaphone system. During silent films, a pianist, theatre organist, or, in large cities, even a small orchestra would often play music to accompany the films. Pianists and organists would either play from sheet music or improvise; an orchestra would play from sheet music.
