Blackmagic Design recently announced the public beta of Blackmagic Raw, a new and very modern codec that combines the quality and benefits of Raw with the ease of use, speed and file sizes of traditional video formats. Blackmagic Raw is a more intelligent format that gives customers stunning images, incredible performance, cross platform support and a free developer SDK.

The Blackmagic Raw public beta will be demonstrated on the Blackmagic Design IBC 2018 booth at #7.B45. Customers can download the public beta for use with URSA Mini Pro cameras via the Blackmagic Camera 6.0 Beta Update. In addition, DaVinci Resolve 15.1 Update, which includes support for Blackmagic Raw, is also available free of charge from the Blackmagic Design website.

Blackmagic Raw has been in development for years and is a next generation hybrid codec that features multiple new technologies such as an advanced de-mosaic algorithm, extensive metadata support, highly optimised GPU and CPU accelerated processing and more. It can be used from acquisition throughout post production for editing and colour grading, all from a single file.

Traditional Raw codecs have large file sizes and are processor intensive, making them hard to work with. Video file formats are faster, but suffer quality problems due to the use of 4:2:2 video filters that reduce colour resolution. Blackmagic Raw solves these problems with an intelligent design that moves part of the de-mosaic process into the camera where it can be hardware accelerated by the camera itself. This results in incredibly efficient encoding that gives customers the same quality, bit depth, dynamic range and controls as Raw, but with much better performance and smaller file sizes than most popular video codecs. Because the processor intensive partial de-mosaic is done by the camera hardware, software such as DaVinci Resolve doesn't have to do as much work decoding the files. In addition, GPU and CPU acceleration make decoding of frames incredibly fast, so you get extremely smooth performance for editing and grading.

Blackmagic Raw is much more than a simple Raw container format. Its intelligent design actually understands the camera and the sensor. This means the image data, along with the unique characteristics of the image sensor, are encoded and saved into the Blackmagic RAW file, giving customers much better image quality, even at higher compression settings, as well as total control over features such as ISO, white balance, exposure, contrast, saturation and more.

In addition, Blackmagic Raw uses Blackmagic Design Generation 4 Colour Science for superior imaging that results in reproducing extremely accurate skin tones and gorgeous, lifelike colorus that rival those of cameras costing tens of thousands of dollars more. Images are encoded using a custom non-linear 12-bit space designed to provide the maximum amount of colour data and dynamic range.

Blackmagic Raw also makes it easy for any software developer to access all this technology. The free developer SDK lets any third party software application add Blackmagic Raw support on Mac, Windows and Linux. The Blackmagic Raw developer SDK automatically handles the embedded sensor profile metadata, along with Blackmagic Design colour science, for predictable and accurate image rendering that yields consistent colour throughout the entire pipeline.

Blackmagic Raw features two types of file compression. Customers can choose either constant quality or constant bitrate encoding options, depending on the kind of work they are doing. This lets them prioritise image quality or file size. Constant quality uses variable bitrate encoding so complex frames are encoded at higher data rates to preserve detail and maintain the highest possible quality. Blackmagic Raw Q0 has minimum quantisation and yields the highest quality, while Blackmagic Raw Q5 uses moderate quantisation for more efficient encoding and a smaller file size. Blackmagic RAW 3:1, 5:1, 8:1 and 12:1 use constant bitrate encoding to give customers the best possible images with predictable and consistent file sizes. The ratios are based on the unprocessed file size of a single frame from the camera's sensor, making it easy to understand the relative amount of compression being used.

The pristine camera native quality of Blackmagic Raw Q0 and 3:1 are perfect for effects heavy feature film and commercial work. Blackmagic Raw Q5 and 5:1 are extremely high quality making them great for episodic television and independent films. Blackmagic Raw 8:1 and 12:1 offer high quality and speed, making it suitable for productions that wouldn't normally consider shooting Raw. Now, more customers than ever will be able to use high quality Raw images in an incredibly efficient way that was impossible before.

Blackmagic Raw could entirely change the workflow going from camera through post production, said Kees Van Oostrum, director of Photography and president of the American Society of Cinematographers. A superb image quality, fine detail and incredibly small file sizes could possibly make Blackmagic Raw the go-to format for filmmakers. It will be an important change for post because the editorial team can work with the camera original files, which are fast enough to use for everyday editing. That means less confusion in regards to creative choices I make at the camera. The images can now travel throughout the entire workflow because we're shooting, editing and grading with the same files! Blackmagic Raw could be a game changer in the way films, television shows and commercials are made.

Blackmagic Raw dramatically simplifies and speeds up post production workflows. DaVinci Resolve 15.1, which was also released on 14 September, includes full support for Blackmagic Raw. The performance of Blackmagic Raw is
