Vitaphone

Vitaphone was a used in nearly 2,000 short films from Warner Bros. Entertainment sound film process. The properties were: Image recording with classic camera as Bell & Howell standard including electric motor, sound recording on wax plate. The frame rate is 22 per second. When playing each a classic projector and a mechanically driven turntables are rigidly coupled together, the records of 17 inches in diameter ( about 43 cm) are sampled at 33 ⅓ revolutions per minute, from the inside out. The Filmakt a maximum of 1000 feet length ( 300 m ) is synchronized with the associated disk. The duration of Akt and plate is on average 12 minutes. The film sheets are only recorded one side and wearing a pressed arrow when groove beginning. The projectionist can hang up the Stylus exactly arrowhead, while the copy of the film has copied a starting image that comes to stand in front of the picture window.

Vitaphone 1924 stood fully available to the industry. It first emerged short films of an advertising nature, before Warner Bros. produced the first full-length film with the system. Don Juan and The Jazz Singer must be enjoyed to this day with caution if you have to expect that they are played with 24 or 25 frames per second. The Al Jolson's voice too high should notice when The Jazz Singer pursued on TV or video.
