What is CinemaDNG?
The CinemaDNG Initiative offers a solution to interoperability problems that arise from proprietary raw digital cinema formats by defining a single open file format for digital cinema files to streamline workflows and enable easy archival and exchange of files. The CinemaDNG file format ensures the preservation of a pristine version of the original raw image and its associated metadata. As cinema production becomes completely digital, CinemaDNG fulfills the same role as the original film negative. Based on the successful DNG file format for still photography, the CinemaDNG file format adds features for cinema-related workflows, as well as support for XMP metadata. You can learn more about the DNG format and XMP metadata on Adobe.com.

What are the advantages of CinemaDNG for content producers?
Proprietary raw file formats are specific to certain manufacturers or cameras. This presents workflow and interoperability roadblocks since content producers are limited to hardware and software solutions that support the format from their camera. By using the CinemaDNG format, content producers can simplify their workflows and ensure maximum compatibility. Content producers also bear the risk that particular raw formats will not be supported in the future. Business dynamics cause cameras to be discontinued and proprietary raw formats to be abandoned. Like the original film negative, the CinemaDNG format is designed to archive pristine data in a format that will be available to content producers for many years.

What are the advantages of CinemaDNG for manufacturers?
The CinemaDNG format removes barriers to new camera adoption since files from new models will be instantly supported by more applications. Manufacturers can reduce development costs by removing the need to develop proprietary formats and conversion utilities. CinemaDNG files may contain proprietary metadata, which allows for product differentiation.

What are RAW images files?
A raw image is an unprocessed image taken from a digital camera's image sensor.

How does CinemaDNG compare to DPX?
The DPX file format is designed for workflows that originate on film. Its goal is to represent the characteristics of film and not to preserve raw data from digital cinema cameras. CinemaDNG, in contrast, is designed specifically for workflows using digital cinema cameras—where physical film is not used.

Will the Adobe DNG converter work with CinemaDNG sequences?
Yes, it does.

What metadata is required for CinemaDNG?
Same as for DNG.

Is there a CinemaDNG logo that I can use in my product or web page?
Yes, there is. Learn more about and download the CinemaDNG logo package.
