CinemaDNG

[1] CinemaDNG caters for sets of movie clips, each of which is a sequence of raw video images, accompanied by audio and metadata.

[2] The emphasis is on having a systematic structure that supports the very complicated workflows, involving many stages and suppliers and software and hardware components, of movie development.

[28] The CinemaDNG specification is largely about this systematic directory structure and the requirements and constraints that ensure that individual files fit within it.

If CinemaDNG follows the same sort of path to standardization as DNG, (or indeed, PDF), there will first be a period while the specification is tested in the marketplace to ensure that it works in practise as well as theory.

In November 2014 Blackmagic Design introduced an extension to the CinemaDNG format in the form of a lossy compression scheme used in their URSA cameras.
