Only if the anamorphic lens for recording and projection are used, the aspect ratio deviates to the film material by a factor of the width thereof from compression.
35 mm 70 mm: Both Cinemascope 35 mm with 4 Perforationsschritten per image and anamorphic projection (22 mm × 18 mm ) and 70 mm projection with 5 Perforationsschritten per frame ( 52.2 mm × 23.0 mm) are common.
Integrated components of film formats
These include film cassettes and film loader. Cartridges are disposable, loaders can be used again and again. The Super -8 format is inextricably linked with a disposable cartridge, as single -8.
