The Cineon System was a ground breaking computer based digital film system created by Kodak in the early 1990s. It was an integrated suite of components consisting a film scanner, a film recorder and workstation hardware with software (the Cineon Digital Film Workstation) for compositing, effects, image restoration and color management.
The system was first released in September 1992 to Cinesite Hollywood. The workstations were initially built on Sun-Transputer based hardware. In July 1993 version 2.1.3 of the software was released for Silicon Graphics Inc (SGI) Onyx hardware. The software was withdrawn from sale by 1997, although a number of customers continued to use it beyond that date. As an end-to-end solution for 4K, 10 bit digital film production, the system was well ahead of its time. The three major components of the system (scanner, workstation software, and recorder) have all received separate AMPAS Scientific and Technical Awards.
The project was also responsible for the creation of the Cineon ( .cin) 10 bit log file format designed to handle digital film frames. Although the product is no longer for sale, Cineon file format that Kodak defined was for a long time commonly used in the film visual effects world, and formed the basis for the SMPTE-standardised Digital Picture Exchange (DPX) format.
The Cineon file format was designed specifically to represent scanned film images, and it has some interesting differences from other formats such as TIFF and JPEG:
Among others FFmpeg and XnView claim to support .cin and .dpx.
Conversions to the Cineon format were defined in a Kodak document by Glenn Kennel. The SMPTE standardized the format further into a related format called DPX which can store more varieties of image information as well as additional header information.
