scope:

This standard defines archive frame rates for D-Cinema that are in addition to the primary frame rates of 24 and 48 fps and the additional frame rates of 25, 30, 50 and 60 fps. These archive frame rates are defined to ensure that the artistic intent of the content producer can be maintained at the point of delivery. All other parameters defined by SMPTE ST 428-1 remain as specified.

This document is part of a suite of SMPTE engineering documents. This part defines the archive frame rates at 16/1, 200/11 (=approx 18.18181818), 20/1 and 240/11 (=approx 21.8181818) frames per second and defines the resulting audio samples per edit unit.
