DNG "Digital Negative" file format is a standardized and hardware agnostic way to store RAW high quality image data based on TIFF. > Digital Negative (DNG) is a patented, open, lossless raw image format developed by Adobe and used for digital photography. Adobe's license allows use without cost on the condition that the licensee prominently displays text saying it is licensed from Adobe in source and documentation, and that the license may be revoked if the licensee brings any patent action against Adobe or its affiliates related to the reading or writing of files that comply with the DNG Specification. \- via [Wikipedia](https://en.wikipedia.org/wiki/Digital_Negative) # CinemaDNG CinemaDNG is an extension of the DNG format for use with video. Typically each frame of the video is captured as an individual file in sequence. > CinemaDNG is the result of an Adobe-led initiative to define an industry-wide open file format for digital cinema files. CinemaDNG caters for sets of movie clips, each of which is a sequence of raw video images, accompanied by audio and metadata. \- via [Wikipedia](https://en.wikipedia.org/wiki/CinemaDNG) > 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. This format uses a 12-bit Huffman Coding by patching jpeg-9a for 12-bit support. These CinemaDNG files are supported by Blackmagic Design's own DaVinci Resolve software, slimRAW and Fast CinemaDNG Processor. > > The adoption of CinemaDNG among camera manufacturers appears to be hindered by Red Digital Camera’s patent US9245314, which covers in-camera recording of lossless compressed raw video. There had been an unsuccessful attempt to invalidate the patent. # Support Support for DNG is built into most proprietary and open source image and video editors across all major platforms. Although there may be exceptions for particularly simple or low-end applications. - [[Blackmagic DaVinci Resolve]] ## CinemaDNG Unlike DNG, CinemaDNG has not been as widely embraced, due largely to RED Camera's patent trolling of many other camera manufacturers that have tried to implement it internally. Blackmagic even went so far as to remove support for it in most of their cameras. Sigma, still uses it, though it is not clear how, perhaps because the 12-bit codec cannot be used internally. # See Also - [[SlimRAW]] - [FastCinemaDNG](https://www.fastcinemadng.com/download/download.html) # References ```cardlink url: https://ymcinema.com/2019/03/19/the-obsolescence-of-cinemadng-from-digital-negative-to-blackmagic-raw/ title: "The Obsolescence of CinemaDNG: From Digital Negative to Blackmagic RAW - YMCinema - News & Insights on Digital Cinema" description: "CinemaDNG and Blackmagic were best friends. Nevertheless, the codec has been removed on the last update (Blackmagic Camera 6.2) and was replaced by Blackmagic RAW (BRAW). Why? Read below. The history of Cinema DNG DNG for photography, CinemaDNG for videography DNG (Digital Negative) has been developed by Adobe to standardize the way that digital RAW data can be stored and used by photographers. The fact that there were hundreds of RAW type files made it extremely hard for developers to adapt software utilizing RAW files and thus the DNG came to the rescue. Photographers could take the DNGs, make changes" host: ymcinema.com favicon: https://i0.wp.com/ymcinema.com/wp-content/uploads/2018/07/cropped-Company-Logo.png?fit=32%2C32&ssl=1 image: https://i1.wp.com/ymcinema.com/wp-content/uploads/2019/03/No-More-DNGs-e1552925865330.jpeg?fit=1886%2C1080&ssl=1 ```
