“Todd-AO”的意思、由来-开放百科全书

Todd-AO is an American post-production company founded in 1953, providing sound-related services to the motion picture and television industries. The company operates three facilities in the Los Angeles area. Todd-AO is also the name of the widescreen, 70 mm film format that was developed by Mike Todd and the American Optical Company in the mid-1950s. Todd-AO had been founded to promote and distribute this system.

History

Todd-AO began as a high resolution widescreen film format. It was co-developed in the early 1950s by Mike Todd, a Broadway producer, in partnership with the American Optical Company in Buffalo, New York. It was developed to provide a high definition single camera widescreen process to compete with Cinerama, or as characterized by its creator, "Cinerama outta one hole". Where Cinerama used a complicated setup of three separate strips of film photographed simultaneously, Todd-AO required only a single camera and lens.

The company's focus began to shift after Mike Todd's sudden death in an airplane accident in 1958. The 70 mm Todd-AO process was adopted by Panavision, Cinerama and others. As the production and exhibition markets became saturated with Todd-AO System hardware, the focus of the company gradually began to narrow down to the audio post-production side of the business, and Todd-AO became an independent sound mixing facility for commercial motion picture films and television after acquiring Glen Glenn Sound in 1986.

In May 2014, Todd-AO's parent company, Todd Soundelux, filed for Chapter 11 bankruptcy protection.^[1] As part of the bankruptcy proceedings, the company closed its Hollywood and Santa Monica facilities, leaving only their Burbank location operational.^[2]

On November 17, 2014, Sounddogs acquired the Todd-Soundelux Trademarks (Todd AO and Soundelux) and Copyrights (Sound Effects Library) through Federal Bankruptcy Court (Central District Case No. 2:14-bk-19980)^[3]

Todd-AO process {{anchor|process}}

The Todd-AO process uses two separate film stocks; a 65 mm negative is used during production and then used to produce the 70 mm positives for distribution. The sprocket holes perforations on the two are the same, and the positives are printed using contact printing with the negatives centered on the larger 70 mm film. Contact printing was used on prints that were to be "double system," using a separate, synchronized 35 mm full-coat magnetic film for the 6 sound tracks, in addition to the 70 mm film for the picture. The much more common 70 mm release prints used a slightly optically reduced picture, and placed 4 of the soundtracks on either edge outside of the perforations, and 2 more soundtracks inside the perforations, providing a total of 6 soundtraks, on a 7.5 mm magnetic surface. It is a common error to suppose that only 5 mm of space was devoted to the soundtracks, perhaps because writers do the math and find that 70 - 65 = 5, not allowing for a slightly reduced picture area to accommodate 2 tracks inside the sprocket holes, as well as 4 outside, and perhaps because the souvenir program for Around the World in 80 Days (1956) made this very same error! Anyone with a release print in front of him would immediately see the tracks between the picture and the holes, as well as the wider tracks (to hold 2 tracks each) outside the holes. In fact, they can be seen in Figure 1 of this article, above the caption "positive 70 mm." Todd-AO soundtracks were very high fidelity, indeed, and could hold their own with modern digital tracks above 40 Hz. Even though there were no subwoofers in theaters in those days, Todd-AO delivered high impact bass using crisp sounding horn loaded speakers. Four lens options covered a 128, 64, 48 or 37 degree field of view. The aspect ratio of this format was 2.20:1.

Both film sizes had been used in the past, in the 70 mm Fox Grandeur process in 1929–1930, however Todd-AO's physical format was not compatible with this format. The use of 65 mm photography and 70 mm printing became the standard adopted by others: Super Panavision 70 (essentially the Panavision company's version of Todd-AO) and Ultra Panavision 70 (the same mechanically, but with a slight 1.25:1 anamorphic squeeze to accommodate extremely wide aspect ratio images) are both 65/70 processes. The Soviet film industry also copied Todd-AO with their own Sovscope 70 process, identical, except that both the camera and print stock were 70 mm wide.

The IMAX format also uses 65 mm camera and lab film to create 70 mm prints for projection (also known as the 65/70 mm process); conforming to the pitch and perforation standard for 70 mm Todd-AO film. However, IMAX frame is 15-perfs long and runs horizontally through the projector, whereas the Todd-AO frame is only 5-perfs high and runs vertically through the projector.^[4]

The original version of the Todd-AO process used a frame rate of 30 frames per second, faster than the 24 frames per second that was (and is) the standard. The difference does not seem great, but the sensitivity of the human eye to flickering declines steeply with frame rate and the small adjustment gave the film noticeably less flicker, and made it steadier and smoother than standard processes. The original system generated an image that was "almost twice as intense as any ever seen onscreen before, and so hot that the film has to be cooled as it passes through the Todd-AO projector".^[5]

Only the first two Todd-AO films, Oklahoma! and Around the World in Eighty Days, employed 30 frames per second photography. Because of the need for conventional versions at 24 frames per second, every scene of the former film was shot twice in succession: once in Todd-AO and once in 35 mm CinemaScope. The latter film was shot with two 65 mm Todd-AO cameras simultaneously, the speed of the second camera was 24 frames per second for wide release as optical reduction prints. All subsequent Todd-AO films were shot at 24 frames per second on a 65 mm negative and optically printed to 35 mm film as needed for standard distribution.^[6] In all, around 16 feature films were shot in Todd-AO.

Todd-AO was developed and tested in Buffalo, New York at the Regent Theatre. Richard Rodgers and Oscar Hammerstein II went there to see Todd-AO test footage, which led them to approve its use for Oklahoma!. Ampex Corporation engineers were in charge of developing the Todd-AO sound system. Ampex would later go on to manufacture the sound system, including selectable four-track composite (CinemaScope) or six-track composite (Todd-AO) or four-track interlocked or six-track interlocked or optical sound sources.

The Todd-AO Company also offered a 35 mm anamorphic process technically similar to 35 mm Panavision or CinemaScope. This may cause some confusion if a Todd-AO credit (not necessarily the more specific Todd-AO 35 credit) appears in some widescreen films made in the 1970s and 1980s. It becomes even more confusing as 70 mm prints were made for films which, unlike earlier pictures made in the process, were shown in multiplexes, like Dune and Logan's Run.

During the late 1970s through the early 1990s 65 mm photography such as that used in processes like Todd-AO or Super Panavision became rare. However, some major films had 70 mm prints made by blowup from 35 mm negatives mostly for the benefit of six-track sound. These prints would typically play only in a few theatres in a few large cities while everyone else viewed the film in 35 mm. The advent of multichannel digital sound in the 1990s obviated these very expensive prints. "Blow-up" 70 mm prints also followed the Todd-AO layout, although in the case of films made with a 1.85:1 aspect ratio, it was retained in the 70 mm version, with the sides of the 70 mm frame left black.

Curved screen vs. flat

While Todd-AO was intended to be "Cinerama out of one hole", the extreme wide angle photography and projection onto a very deeply curved screen (which is what that would imply) saw little use. Most Todd-AO theatre installations had only moderately curved screens and the extreme wide angle camera lenses were used only on a few shots here and there. Todd-AO films made after 1958 used a conventional flat widescreen, and resembled ordinary films, except for their greater clarity and six-track stereo sound. A variation on Todd-AO called Dimension 150 did, however, make use of Cinerama-like deeply curved screens. Only two films were made in Dimension 150 – In the Beginning, directed by John Huston, and Patton, starring George C. Scott. In some venues, however, Todd-AO and Dimension 150 films received their first run in Cinerama theatres in order that they be shown on a deeply curved screen – such as the first Atlanta showings of The Sound of Music.^[7]

Todd-AO and roadshows

Todd-AO films were closely associated with what was called roadshow exhibition. At the time, before multiplex theatres became common, most films opened at a large single screen theatre in the downtown area of each large city before eventually moving on to neighborhood theatres. With the roadshow concept, a film would play, often in 70 mm at a movie palace downtown theatre exclusively, sometimes for a year or more. Often a "hard ticket" policy was in effect, with tickets sold for specific numbered seats, and limited showings per day. Most Todd-AO films through the late 1960s, including Those Magnificent Men in Their Flying Machines and The Sound of Music, were initially shown on a roadshow basis.

In some US cities, individual theaters were converted for use in the 1950s as dedicated Todd-AO "Cinestage" showplaces. These theaters showed exclusive roadshow engagements of Todd-AO and other 70 mm films on large, deeply curved screens. They included the Rivoli Theatre in New York City,^[8] the Cinestage Theatre in Chicago,^[9] and Hunt's Cinestage Theatre in Columbus, Ohio.^[10]

The roadshow era ended in the early 1970s, although a very few films (among them Gandhi) were shown in roadshow format after that.

Todd-AO attempts 35 mm widescreen

In the 1970s, under the leadership of Dr. Richard Vetter, Todd-AO made an attempt to compete with Panavision in the 35 mm motion picture camera rental market. The company built a series of anamorphic lenses in the 2.35:1 scope format, and owned several camera bodies (Mitchell and Arriflex) that they would provide with the lens package. Of the five original Planet of the Apes films, Conquest of the Planet of the Apes is the only entry filmed in Todd-AO 35 using ARRI Arriflex 35IIC cameras with lenses provided by The Carl Zeiss Group, (the other Apes pictures were filmed in Panavision).

By the 1980s the venture was moribund, and was abandoned. Eventually all of the Todd-AO cameras and lenses, both 35 mm and 65 mm (70 mm), were sold to Cinema Products in Los Angeles. Cinema Products is now defunct.
