NBN ISO 12222:2021

1.1 This document specifies the position and dimensions of machine-readable identification numbers
on 16 mm, 35 mm and 65 mm motion-picture film. These numbers are intended to be a machine-readable
version of the latent image key number. This document also specifies the encoding format to be used
for these machine-readable numbers, as well as the area scanned and the spectral characteristics of the
scanner.
1.2 This document also specifies the position, dimensions and content of human-readable
identification (key) numbers for use on 16 mm, 35 mm and 65 mm motion-picture films intended for
original photography or intermediate printing which also include the machine-readable key number
described in 1.1.
NOTE These numbers normally are exposed onto the film at the time of manufacture.
1.3 This document further specifies an area that may be used for optional manufacturer-specific film-
type identification information.
1.4 This document also specifies an area on the film which is not to be exposed by the film manufacturer,
thus leaving it available for customer data recording.
1.5 Finally, this document specifies an optional frame line index mark for 35 mm and 65 mm film.
