Technology.am (Sept. 11, 2009) — Based on the successful DNG file format for still photography, Adobe has released a beta version of a file format called CinemaDNG that is applied to video for higher-end cameras such as SLRs. DNG records the raw data from the image sensor with no in-camera processing.

adobe The CinemaDNG format is designed for storing high-resolution image streams in camera raw format. CinemaDNG is an open, documented format leveraging standard formats for video and imaging — DNG, TIFF, TIFF/EP, MXF, XMP. Each image is encoded using the DNG image format. The image stream can be stored in one of two formats: either as video essence in an MXF file, or as a sequence of image files in a file directory.

In many digital cinematography workflows, captured content is processed by software and hardware in the camera before it is saved to a storage device—and assumptions made during this processing could irrevocably damage the original imagery. Cinema DNG avoids these problems by capturing raw digital data directly from the camera’s sensor, giving artists the power to make qualitative judgments after imagery has been saved to disk.
