SMPTE 254 – Motion-Picture Film (35-mm) – Manufacturer-Printed Latent-Image Identification Information (Revision of SMPTE 254-2002)

1 Scope

1.1 This standard specifies the position and dimensions of machine-readable identification numbers. Thesenumbers are intended to be a machine-readable version of the latent image key number. This standard alsospecifies the encoding format to be used for these machine-readable numbers, as well as the area scannedand 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 printingwhich also include the machine-readable key numbers described in 1.1. These numbers normally will beexposed 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-typeidentification information.

1.4 This standard also specifies an area on the film which is not to be exposed by the filmmanufacturer, thus leaving it available for customer data recording.

1.5 Finally, this standard specifies an optional frameline index mark.
