DNxHR

In 2014 AVID introduced its Codec DNxHR.

In September 2014 AVID introduced a family of new codecs supporting UHD and 4K resolutions called DNxHR. This is backwards compatible with the Avid DNxHD codec (which is limited to resolutions up to 1920x1080 HD). DNxHD continues to be used and supported by AVID. .

The DNxHR codec has five different versions:

●    DNxHR LB (Low Bandwidth) 8-bit, 4:2:2, offline quality
●    DNxHR SQ (Standard Quality) 8-bit, 4:2:2, sufficient for some TV deliveries
●    DNxHR HQ (High Quality) 8-bit, 4:2:2
●    DNxHR HQX (High Quality Extended) 10-bit/12-bit, 4:2:2, suitable for some UHDTV deliveries
●    DNxHR 444 (Full RGB) with 10-bit/12-bit, 4:4:4, suitable for some cinema masters

The DNxHR codec fits into the ‘resolution independent’ architecture of Avid’s Media Composer enabling flexible, end-to-end workflows for high resolution projects which can now use the compression offered by DNxHR to reduce the large bandwidths of high resolution material.

The high-quality versions of DNxHR codecs are visually lossless. The DNxHR codec can be wrapped in both MXF and MOV containers and like DNxHD, DNxHR can be used by DaVinci Resolve 12 and Adobe Premiere Pro CC as well as other software packages.
