Adobe has introduced a beta version of CinemaDNG, a new file format for raw video. More details over at Adobe Labs.
When film is used as the capture medium, cinematographers take great care when handling source film footage. Developed in response to the move to digital capture by many cinematographers, CinemaDNG is a digital replacement for film negatives that helps cinematographers ensure that their digitally captured scenes retain their pristine quality so they can be used to deliver the film’s artistic vision. CinemaDNG is similar to the popular DNG format used for digital still photography but adds elements to specifically support digital cinema workflows.
