RP 195:2004 - SMPTE Recommended Practice - Use of the Reference Mark in Manufacturer-Printed Latent Image Key Numbers for Unambiguous Film Frame Identification

This practice specifies the procedure for unambiguously identifying film frames which have been exposed on film stock carrying latent-image key numbers of an incompatible repetition rate. — Particular examples are the identification of 35-mm 3-perforation frames on stock conforming to SMPTE 254, and the identification of 65-mm 15-perf frames on stock conforming to ANSI/SMPTE 270. The procedure is quite general and may be extended to other frame sizes on other film stocks. — This practice also specifies a standard notation for film positions identified according to this practice. The standard notation is used in relevant SMPTE practices for film-to-tape transfer and negative conforming.
