Cineon

The Cineon System was one of the first computer based digital film systems, created by Kodak in the early 1990s. It was an integrated suite of components consisting a motion picture film scanner, a film recorder and workstation hardware with software (the Cineon Digital Film Workstation) for compositing, visual effects, image restoration and color management.

The system was first released in September 1992 to Cinesite Hollywood. The workstations were initially built on Inmos-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 The software was withdrawn from sale by 1997, although a number of customers continued to use it beyond that date.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 resolution, 10 bit digital film production and digital intermediate, the system was one of the first. The three major components of the system (scanner, workstation software, and recorder) have all received separate AMPAS Scientific and Technical Awards.

The Cineon 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 newer SMPTE-standardised Digital Picture Exchange (DPX) format.

The Cineon file format was designed specifically to represent scanned film images, and thus has some differences from other formats such as TIFF and JPEG:

Programs like FFmpeg and XnView report 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.

The Cineon 10 bits per pixel color space provides 1024 levels of color as opposed to 256 levels of color in 8 bits per pixel color space. 10 bit YUV and 10 bit RGB are the industry standard. The standard documented and recognized by the Society Of Motion Picture Television Engineers: SMPTE 259M, SMPTE 292M, SMPTE 296M, SMPTE 372M. A .fido file is a type of Cineon Graphics Data File format.

From the late 1980s Glenn Kennel was the principal architect of the Cineon digital film system. Kennel led the development of the Cineon CCD film scanner and laser Film recorder (the Lightning film recorder) in Rochester NY. From February 1990, the Cineon workstation software was written by a team based at Kodak in Melbourne, Australia led by Lindsay Arnold. In early 1995, development moved to Kodak in Rochester, NY, where it was led by David Cok and Jim Minno. In about 1996, software development moved to Palo Alto, California.
