Īt the April 2010 NAB Show, Digital Video Systems launched the first Windows 7 platform with the ability to encode to all the varieties of Apple ProRes at speeds far faster than real time on their Clipster product.

Īpple released ProRes bundled with other pro codecs as a download for users with "qualifying copies of Final Cut Pro, Motion, or Compressor" installed, for OS X with QuickTime 7.6 and newer.

Without Final Cut Pro installed, QuickTime Player can also be used to capture ProRes 422 video from any compatible attached camera, using the "Maximum" quality setting when producing a Movie Recording.

Installing Final Cut Pro will install the ProRes codecs for encoding files on macOS. On 1 October 2011, JCodec introduced an open source ( FreeBSD License) pure Java decoder for ProRes 422, a translate of FFmpeg version. On 15 September 2011, FFmpeg introduced a free decoder for ProRes 422 for libavcodec.įFmbc, a fork of FFmpeg customized for broadcast and professional usage, supports ProRes 4 files. On 28 August 2008, Apple introduced a free ProRes QuickTime Decoder for both Mac and Windows that allows playback of ProRes files through QuickTime. ProRes RAW therefore aims at quality and better color reproduction, rather than performance. It is built upon the same technology as other ProRes codecs, but is directly applied to the raw data coming from the sensor, thus delaying the debayering process to the post-production stage. Alpha channel support at up to 16-bit sample depth.It has a target data rate of approximately 500 Mbit/s for 4:4:4 sources at 1920x1080 and 29.97 fps, and requires OS X v10.8 (Mountain Lion) or later.

ProRes 4444 XQ was introduced with Final Cut Pro X version 10.1.2 in June 2014. 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) 100Mbit/s as well as ProRes Proxy for HD 45Mbit/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.
