DNxHR codec

Avid DNxHR, which stands for "Digital Nonlinear eXtensible High Resolution", is a lossy UHDTV post-production codec engineered for multi-generation compositing with reduced storage and bandwidth requirements. The codec was specifically developed for resolutions considered above FHD/1080p, including 2K and 4K. 8K resolution is currently not supported. DNxHD will continue to be used for HD resolutions.[1]

On September 12, 2014, Avid Technology, Inc. announced the DNxHR codec as part of a broader "Avid Resolution Independence" announcement at their Fall 2014 Avid Connect event, which was held during the IBC 2014 conference in Amsterdam, Netherlands.[1]

On December 22, 2014, Avid released Media Composer 8.3 which included support for 4K project formats and the DNxHR codec. Further details for the DNxHR codec were outlined in the "Avid High-Resolution Workflows Guide - December 2014".[2]
