Premise: 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, 4K and 8K resolution. DNxHD will continue to be used for HD resolutions.
Hypothesis: Avid DNxHR, which stands for "Digital Nonlinear Extensible High Resolution", is a gainy UHDTV post-production codec engineered for multi-generation compositing with reduced storage and bandwidth requirements
