DNxHR is a high-definition video post-production codec developed by Avid technology.

It extends DNxHD to resolutions over full HD and to cinema quality. DNxHR has HD, 2K, UHD and 4K profiles, with 5 quality flavors: LB (low bandwidth), SQ (standard), HQ (high-quality 8bit), HQX (high-quality 12bit) and 444.

DNxHR footage is usually found in MXF video files, but it can also be wrapped into QuickTime .mov containers thanks to the standalone codec both for Windows and Mac.

How to repair a corrupt DNxHR clip?

Whether it's a damaged disk, a corrupt MXF file or a damaged QuickTime movie, the easiest way is certainly to ask our Treasured Repair Service to do it for you.
But for those who can program, here you have a few tips:

Each DNxHR frame starts with this sequence of bytes:

00 02 80 03 - for 2K and HD profiles
00 03 8C 03 - for UHD and 4K profiles

Frame length is fixed and depends on DNxHR profile and flavor (LB, SQ, HQ, HQX or 444).
