ST 254:2008 - SMPTE Standard - Motion-Picture Film (35-mm) — Manufacturer-Printed Latent-Image Identification Information

1.1 This standard specifies the position and dimensions of machine-readable identification numbers. These numbers are intended to be a machine-readable version of the latent image key number. This standard 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 standard also specifies the position, dimensions, and content of human-readable identification (key) numbers for use on 35-mm motion-picture films intended for original photography or intermediate printing which also include the machine-readable key numbers described in 1.1. These numbers normally will be exposed onto the film at the time of manufacture. — 1.3 This standard further specifies an area that may be used for optional manufacturer-specific film-type identification information. — 1.4 This standard 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 standard specifies an optional frameline index mark.
