Apple ProRes Raw is one of the most popular video formats in professional video production and post-production. ProRes Raw is a new codec technology developed by Apple for high-quality, high-performance editing in Final Cut Pro X.
The Apple ProRes codec family provides an unparalleled combination of real-time, multistream editing performance, and impressive image quality preservation. ProRes RAW is based on the same principles and underlying technology as existing Apple ProRes codecs, and is ideal for High Dynamic Range (HDR) content creation in Final Cut Pro X, Motion, and Compressor.
ProRes RAW brings the same great performance, quality, and ease of use to raw video that ProRes has brought to conventional video. When you store a clip in the ProRes RAW format rather than in a proprietary camera raw format, you get more control over the processing of the image, including demosaicing, linear-to-log conversions, and custom LUTs.
With ProRes RAW, you can import, edit, and grade video with RAW data straight from your camera sensor — without slowing down your edit. ProRes RAW also provides maximum flexibility for adjusting the look of your video while extending brightness and shadows.
You can render and export faster with ProRes RAW than you can with other raw formats—ProRes RAW is optimized for macOS and the latest Mac computers. And you can fit more footage on every card because ProRes RAW files are smaller than standard formats.
You can choose between two ProRes RAW compression levels: ProRes RAW and ProRes RAW HQ. Both compression levels achieve excellent preservation of raw video content, with Apple ProRes RAW HQ providing additional quality at a higher data rate. ProRes RAW data rates can vary significantly based on image content, because the codec is designed to maintain constant quality and pristine image fidelity for all frames.
Raw video playback requires decoding the video bit stream and converting the decoded raw image. Final Cut Pro streamlines and optimizes this conversion process for Apple ProRes RAW files. When you use ProRes RAW with Final Cut Pro, you get the same real-time, multistream video editing performance you experience with Apple ProRes RAW as you do with standard media.
View ProRes RAW on your Mac
After you install Pro Video Formats on your Mac, you can view ProRes RAW files with QuickTime Player and Quick Look. Since ProRes RAW captures high-dynamic-range data directly from the camera sensor, footage may look overexposed on the display of your Mac.
Because ProRes RAW is an acquisition format created by cameras and video recorders with RAW data straight from your camera sensor, it’s not possible to create ProRes RAW files from video software. To export ProRes RAW files to other formats, use Final Cut Pro X, Motion, or Compressor. You can’t export ProRes RAW to other formats with QuickTime Player.
Digital camera sensors consist of an array of millions of light-sensitive elements called photosites that convert the light exposed to the sensor to an array of digital intensity values. To capture color, most current digital cameras use a color filter array that yields a single primary color value (such as red, green, or blue) at each photosite location. This color filter arrangement is known as a Bayer pattern, where each two-by-two group of photosites consists of one red, one blue, and two green sensor elements. In contrast, conventional RGB images consist of not one but three primary color values (red, green, and blue) at each pixel location.
The process of converting a Bayer pattern image to a conventional RGB image is known as demosaicing. For conventional video, demosaicing and other processing operations are performed within the camera to produce viewable RGB images that can be recorded into a video file.
At playback time, an application needs only to decode the conventional video file to produce RGB images that can be edited and displayed. The demosaicing and processing have already been performed by the camera at capture time and are “burned in.”In contrast, ProRes RAW directly encodes the Bayer pattern image. Demosaicing and processing are deferred to the time of playback and are performed by application software.
This requires more computation during playback but allows for greater flexibility. Just as different image and video codecs must make tradeoffs between compression rate, quality, and complexity, demosaicing algorithms must make tradeoffs between speed, quality, and other factors. Using ProRes RAW lets you defer the choice of demosaicing algorithm until post-production and allows you to take advantage of raw processing enhancements and demosaicing algorithm improvements in future software.
Using Log Conversion with Built-in Camera LUTsMost professional video cameras today support recording in a log format. Using log enables a higher dynamic range of light levels to be represented compared to standard video gamma functions. Because many color-grading workflows are based on working with log video, Final Cut Pro can automatically apply a log conversion setting to ProRes RAW media files during import. With log conversion applied, ProRes RAW files behave just like conventional log video and can be edited the same way.Using built-in log conversion allows you to color correct ProRes RAW video as if it were SDR or HDR video, depending on your library color-processing setting. When your library is set to Standard color processing, you can color correct ProRes RAW video as if it were SDR video. With your library set to Wide Gamut HDR, you can color correct ProRes RAW video as if it were HDR video.RAW to Log Conversion SettingDecoding ProRes RAW directly results in HDR linear values rather than log.
The Raw to Log Conversion setting in the Info inspector applies custom log functions created by different camera vendors so that you can color correct your ProRes RAW files as log video. Because ProRes RAW files contain metadata that identifies the camera manufacturer, Final Cut Pro can apply the correct log function (such as Canon Log 2, Panasonic V-Log, or Sony S-Log3) during import.You can also manually adjust the RAW to Log Conversion setting in the General, Extended, or Settings view of the Info inspector.
