 In
the sixties, in China, a new picture movie film format was created from the
Super 8. The purpose of the chinese authorities
was the development of portable cine equipment to satisfy the cultural life
of the people in mountainous areas and remote areas, and of the Frontier
Guard. This people had no acces to a medium of mass culture as important as
the cinematographic medium. About 1965,
the Ministry of Culture of China approved making a chinese portable cine projector.
In 1966, the Beijing Film Equipment Factory and the Beijing Research Institute created the 8.75 mm motion picture film. The same year, the Nanjing Film Equipment Factory was designated to starting the development of a 8.75 mm cine projector. In October 1967, the goverment authorities designated the 8.75 mm format as means of development in rural areas, supplemented by 16 mm, 35 mm. And in the same year, the first prototype of projector was finished, the model 8.75-1 (but the serial production of this model started in 1970, after the 8 protoypes was created and subsequently improved). In 1968, Shangai Film Equipemnt Factory developed a method to printing 8.75 mm film.
The 8.75 mm was a lightweight equipment, because it traveled to distant provinces. In these remote areas, there was no electric current. A power generation equipment was necessary be transported with the projectors. The total weight of projector and generator was over 10 kg. This chinese small format was created from Super 8. The
sprocket holes are similar, but the image area is more large: 4.51 mm x 6.01
mm. The film width is the result of dividing the 35 mm film into 4 strips.
The chinese designers had the folowing premise: the rational use of
film. With this wide, the production of 8.75
film copies from a 35 mm positive film. The sound system was a magnetic
playback, with a high frequeny up to 7 kHz. In the seventies were printed
more than 60,000 films. In the early eighties, the chinese authorities
stopped production in this format when the television became the predominant. |

In later years, other equipment plants were designated
to manufacture cine projectors. The most important was the Zhejiang Film
Equipment Factory. In 1969 started the production of a 8.75 mm projector,
the Zhejiang I. The following model was a Zheijiang II. And in february
1974, this factory made a new projector, the Zhejiang FL. In 1972, Shangai
Film Equipment Factory made a prototype. And, in 1973, the production of
new projector was started in a equipment plant of Shandong.
