DNxHD is a high-definition video post-production codec developed by Avid technology.
It is used mainly in Avid workflows, like in flagship editing app Media Composer.
DNxHD 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.
Recorders like above AJA KiPro Quad can use the DNxHD encoding in their recordings.
Treasured is capable of detecting and previewing DNxHD media in damaged files or disks.
Supported DNxHD profiles include:
- Dimensions: 720p, 1080i and 1080p (all frame rates supported)
- Bit Rates: 36Mbps, 60Mbps, 75Mbps, 90Mbps, 110Mbps, 115Mbps, 120Mbps, 145Mbps, 175Mbps, 185Mbps, 220Mbps
- Bit Depth: 8bit, 10bit depth
DNxHD media is repaired without major problem.

Frame length is fixed and depends on DNxHD profile. Possible values are: 188416, 303104, 458752, 606208, and 917504 bytes.
