Dpx

Digital Picture Exchange (DPX) is a common file format for digital intermediate and visual effects work and is an ANSI/SMPTE standard (268M-2003). The file format is most commonly used to represent the density of each colour channel of a scanned negative in a 10-bit log format where the gamma of the original camera negative is preserved as taken by a film scanner. Other common video formats are also supported. DPX provides a great deal of flexibility in storing color and other information for exchange between production facilities. Multiple forms of packing and alignment are possible.The DPX file format was originally derived from the output file format (.cin) of the Kodak Cineon 'FIDO' film scanner, and has been published by SMPTE as ANSI/SMPTE 268M-2003 (originally was version 1 268M-1994).
