![]() ![]() It has a target data rate of approximately 330 Mbit/s for 4:4:4 sources at 1920x1080 and 29.97 fps It shares many features with other, 422, codecs of Apple's ProRes family but provides better quality than 422 HQ in color detail. ProRes 4444 was introduced with Final Cut Studio (2009) as another in the company's line of intermediate codecs for editing material but not for final delivery. for use in post-production and include support for an alpha channel. ProRes 4444 and ProRes 4444 XQ are lossy video compression formats developed by Apple Inc. Fast encoding and decoding (both at full size and half size).Normal 42 Mbit/s and High-Quality 63 Mbit/s for SD resolution at 29.97.Normal 147 Mbit/s and High-Quality 220 Mbit/s and ProRes (LT) 100 Mbit/s as well as ProRes Proxy for HD 45 Mbit/s for HD resolution at 60i.ProRes 44 XQ samples color in the 4:4:4 schema with a color depth of 10 or 12 bits, and can optionally include an alpha channel. All ProRes422-variants use Chroma subsampling of 4:2:2 at 10-bit color depth. ProRes supports different data rates and different resolutions. In 2018 Apple added a new "ProRes RAW" (compressed Bayer filter) to Final Cut Pro X, after Blackmagic Design implemented compressed Bayer as " CinemaDNG 3:1" and "CinemaDNG 4:1" in their cameras and DaVinci Resolve. ProRes is a DCT scalar based intra-frame-only codec and is therefore simpler to decode than distribution-oriented formats like H.264. It is comparable to Avid's DNxHD codec or CineForm which offer similar bitrates and are also intended to be used as intermediate codecs. The benefit of an intermediate codec is that it offers excellent random access performance in post-production applications, and retains higher quality than end-user codecs while still requiring much less expensive disk systems compared to uncompressed video. This is achieved by only using intra-frame compression, where each frame is stored independently and can be decoded with no dependencies on other frames. ProRes is a line of intermediate codecs, which means they are intended for use during video editing, and not for practical end-user viewing. ProRes is widely used as a final format delivery method for HD broadcast files in commercials, features, Blu-ray and streaming. Much like the H.26x and MPEG standards, the ProRes family of codecs use compression algorithms based on the discrete cosine transform (DCT). It is the successor of the Apple Intermediate Codec and was introduced in 2007 with Final Cut Studio 2. for use in post-production that supports video resolution up to 8K.
