Introduction High Efficiency Image File Format (HEIF) is a file format for individual images and image sequences. It was developed by the Moving Picture Experts Group (MPEG) and is defined by MPEG-H Part 12. In June 2017, Apple announced support for HEIF in macOS High Sierra and iOS 11. Digital Picture Exchange (DPX) is a common file format for digital intermediate and visual effects work and is an ANSI/SMPTE standard. DPX is the worldwide-chosen format for still frames storage in most Digital Intermediate post-production facilities and film labs.
Technical details The HEIF specification also defines the means of storing High Efficiency Video Codec (HEVC)-encoded intra images and HEVC-encoded image sequences in which inter prediction is applied in a constrained manner. The DPX file format was originally derived from the Kodak Cineon open file format (.cin file extension) used for digital images generated by Kodak's original film scanner.
