Todd-AO

Todd - AO was a 1955 movie recording process introduced for 70 - mm - wide screen movies.

Background

Todd - AO was created from an idea by Michael Todd, who was already involved in the development of Cinerama. The trademarked name of the method originated as an acronym from Todd and American Optical. With and for this American Optical Company, he wanted to develop a simpler system with a lens should have the same effect on the audience as the three-lane format of Cinerama. With a spherical lens, the image was recorded with a frame rate of 30 frames per second on a 65 mm film negative. The 70 - mm film screening contained the soundtrack to six Magnettonstreifen. Philips has developed a new movie projector with the name DP70 who could project the film strip on a deeply curved screen by 128 degrees. With an intake of 30 frames per second, which prevented the flicker on a 70 mm roadshow presentation, but no direct copy of the film on 35 mm was possible. The first two films had to therefore be additionally recorded with a frequency of 24 frames per second. For Oklahoma! therefore arose at the same time a 35mm CinemaScope version and for Around the World in 80 days, a second Todd-AO version in reduced speed.

When 20th Century Fox participated in Todd - AO, a number of technical changes have been made. The film has now been recorded with a frame rate of 24 frames per second in order to directly produce 35mm film prints can. In the film screening on a deeply curved Cinerama screen was similar dispensed with the use of a new lens from Bausch & Lomb. Expensive renovations for the theater owners accounted for. With South Pacific, the changes were implemented. 20th Century Fox attacked now for all of its 70 - mm - large-scale productions back to this method. Just watching Porgy and Bess with Columbia, United Artists with Alamo and Universal with Airport produced one film in this format. With Todd -70 is a cheaper variant, which was used only once was.

After the success of the first films Panavision developed his own Todd-AO version. The Super Panavision process which could be rented from the other film studios, became the largest competitors by 20th Century Fox on the 70 - mm film market. As Cinerama successfully started 70 mm films on their deeply curved screens show off, we moved to the development of dimension 150. Behind came Todd-AO only by the advent of 70 - mm blow-up. Although Todd - AO was as have better Bildqualtität on the 35 - mm film, but turning on 65 mm film with further processing to the 70 -mm screening was much more complex and therefore more expensive than on 35 - mm film. The last fully filmed in this format film came in 1971 in the cinemas.

The Karlsruhe film actor castle held annually since 2005, a Todd -AO 70mm Festival.
