dpx

Dpx is the abbreviation for digital picture exchange. It 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 color channel of a scanned negative in a 10-bit uncompressed 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. The 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.
