The Apple ProRes family of video codecs has made it both possible and affordable to edit full-frame, 10-bit, 4:2:2 and 4:4:4:4 high-definition (HD), 2K, 4K, 5K, and larger video sources with multistream performance in Final Cut Pro X. This white paper provides in-depth information about all six members of the Apple ProRes family, including technical specifications and performance metrics.  \nApple ProRes | April 2017 3  \nAuthorized Apple ProRes Implementations  \nApple ProRes is a codec technology developed for high-quality, high-performance editing in Final Cut Pro X. Apple has licensed Apple ProRes to select companies for use in specific products and workflows.  \nIn some instances, unauthorized codec implementations have been used in third-party software and hardware products. Using any unauthorized implementation (like the FFmpeg and derivative implementations) may lead to decoding errors, performance degradation, incompatibility, and instability.  \nFor a list of all authorized Apple ProRes licensees and developers, and for licensing information, go to [support.apple.com/kb/HT5959](support.apple.com/kb/HT5959. If you)[. If you](support.apple.com/kb/HT5959. If you) are using or considering purchasing a product that encodes or decodes Apple ProRes, and that product isnot on this list, contact Apple at [ProRes@apple.com](ProRes@apple.com).  \nApple ProRes | April 2017 4  \nApple ProRes Family Overview  \nApple ProRes codecs provide an unparalleled combination of multistream, real-time editing performance, impressive image quality, and reduced storage rates. Apple ProRes codecs take full advantage of multicore processing and feature fast, reduced-resolution decoding modes. All Apple ProRes codecs support any frame size (including SD, HD, 2K, 4K, 5K, and larger) at full resolution. The data rates vary based on codec type, image content, frame size, and frame rate.  \nAs a variable bit rate (VBR) codec technology, Apple ProRes uses fewer bits on simple frames that would not benefit from encoding at a higher data rate. All Apple ProRes codecs are frame-independent (or “intra-frame”) codecs, meaning that each frame is encoded and decoded independently of any other frame. This technique provides the greatest editing performance and flexibility.  \nA variety of cameras can now capture and record a wider gamut of color values when working in log or raw formats. You can preserve this wider color gamut by recording with the ProRes LOG setting on certain cameras such as the ARRI ALEXA or transcoding from the RED® camera’s REDCODE® RAW format. Final Cut Pro 10.3 or later can process color in wide color gamut and output Apple ProRes files in the Rec. 2020, DCI-P3, or D65-P3 color space. This results in deeper colors and more detail, with richer red and green areas of the image.  \nWith Final Cut Pro 10.3 or later, you can also export Apple ProRes files inside an MXF metadata wrapper instead of exporting .mov files. This makes the exported video file compatible with a wide range of playback systems that rely on the MXF standard for broadcast and archiving.  \nApple ProRes includes the following formats:  \n• Apple ProRes 4444 XQ: The highest-quality version of Apple ProRes for 4:4:4:4 image sources (including alpha channels), with a very high data rate to preserve the detail in high-dynamic-range imagery generated by today’s highest-quality digital image sensors.
