openYCoCg

An experimental video codec, built on the Y′COCG colour space, designed for restoration purposes.

The source code with its brew formula will be available on our GitHub repository, as soon as a beta will be released.

Some Context

  • When working with the old colour processes, used in the during the first half century of cinema, it’s often more effective to handle independently, on one hand, the luma Y′ and, on the other hand, the chroma C1 and C2 components.
  • Working with CO and CG is easier than working with the common CB and CR, because the de-correlation of the colour planes is better and the transcoding from and to R′G′B′ is faster.
