ProRes

A highly efficient video codec for compressing image data up to 5K, developed by Apple.

ProRes is used today for camera recordings as well as in post-production and has become an important standard in the field of codecs / formats. ProRes is also used for the delivery of masters to some broadcasters. Many post production tools can work with ProRes natively. Since this codec is delivered as a component of QuickTime, any software that uses the QuickTime framework is able to decode ProRes. 

This video codec enables recording, editing and finishing at full resolution, in 4:2:2 10-bit or 4:4:4:4 12-bit. 


A number of vendors provide native support for this codec, including ARRI (the Alexa and Amira ranges) and Blackmagic Design which supports ProRes in its cameras as well as its post-production software, Resolve. External recorders from AJA and Atomos can also record in this format. 

Editing and finishing software products which support native processing of ProRes include Avid , Adobe Premiere , Final Cut Pro / X and DVS CLIPSTER , amongst others.

ProRes supports a number of frame sizes (SD, HD, 2K, 4K and 5K) at full resolutions, at all common frame rates up to 60p. It’s important to check the broadcaster’s HD delivery requirements and that your camera or edit settings are correctly configured.

Apple ProRes is an intra-frame codec. Each frame is encoded individually without interpolating intermediate images.  As a result, this codec is particularly suited to video editing, the application for which it was developed. The two ProRes 4444  variants operate at 12-bit  4:4:4 and provide an alpha channel.

The ProRes 4444 XQ variant stands for "extended quality" and is particularly suited for HDR and VFX shots and their further processing. Both 4444 versions are "virtually lossless", i.e., there is practically no visible loss through data reduction.
