This standard defines additional frame rates for D-Cinema that are in addition to the primary frame rates of 24 and 48 frames per second. These additional 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 428-1, D-Cinema Distribution Master (DCDM) — Image Characteristics, remain as specified. This document is part of a suite of SMPTE engineering documents. This part defines the image characteristics of the additional frame rates individually at 25, 30, 50 and 60 frames per second, and also defines the resulting audio samples per edit unit. Other parts will define further provisions to support the additional frame rates defined by this standard.
