After entering the era of sound film, copying was changed to one-sided perforation, and the other side was used as the position of vocal cords (optical vocal cords or magnetic vocal cords). Due to the light weight of 16mm film equipment, low film and processing costs, and the continuous progress of emulsion technology, the clarity and granularity of projected images have been improved, so it is widely used in science and education, news, industry and commerce. At the same time, it is also used for making feature films in cinemas in small and medium-sized towns or projection units in remote areas. Most of the existing rural projection teams in China use 16 mm movies. 16mm film can be shot directly with 16mm film and then printed with 16mm projection copy, or reduced with standard 35mm film.

The original film shot by the system extends horizontally to the sound level area, which makes full use of the effective area of 16mm film and simplifies it. Six kinds.
