Input: original question: Which film festival focuses on [Silent film]?
answer: silent film festival, pordenone silent film festival, mute nights festival...
answer type: Film festival.
auxiliary information: A silent film is a film with no synchronized recorded sound, especially with no spoken dialogue. In silent films for entertainment the dialogue is transmitted through muted gestures, mime and title cards. 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. After the release of The Jazz Singer in 1927, the "talkies", also known as sound film or talking pictures became more and more commonplace. Within a decade, popular widespread production of silent films had ceased, hence production moving into the sound era. A September 2013 report by the United States Library of Congress announced that a total of 70% of American silent feature films are believed to be completely lost.
