DNxHD Codec: A Comprehensive Guide

The Avid DNxHD codec is a popular choice for high-quality video editing with manageable file sizes. Whether you're a beginner or a pro, understanding DNxHD can help improve your workflow. This guide covers what DNxHD codec is, how it works, its benefits, and simple steps for downloading and installing the Avid DNxHD codec.

Part 1. What is DNxHD Codec?

DNxHD (Digital Nonlinear Extensible High Definition) is a video codec created by Avid in 2004 to streamline post-production workflows. It simplifies editing by converting various source formats into a single, high-quality, and efficient format. DNxHD is commonly stored in MXF or QuickTime (.mov) containers and works similarly to JPEG, compressing each frame independently while preserving high image quality at manageable data rates.

Key Features of DNxHD:

• This works with major editing software like Avid Media Composer, DaVinci Resolve, Adobe Premiere Pro, and media players like VLC and QuickTime.
• Cameras from Sony, RED, and ARRI can record directly to DNxHD, usually as proxies alongside higher-quality footage.
• DNxHD consolidates different codecs, resolutions, and frame rates into one editable format, reducing complexity.
• In Avid Media Composer, using the Import function converts source media into DNxHD, standardizing the editing process.
• DNxHD is widely used in the industry for its reliability and performance. It is ideal for projects requiring high-quality visuals without overwhelming storage or computing resources.

Moreover, there are different variants of DNxHD codec. But what type should you use? This barely depends on the amount of footage, your system's performance, and your storage capacity. Here's a simplified guide based on different data rates for 1080p 24fps footage:

Notes:

• For proxy workflows, you can use DNxHD 36 for lightweight editing, as you'll reconnect to high-quality media later.
• For high-resolution editing, use a higher bitrate like DNxHD 175x or DNxHR HQX for better quality.

Remember, DNxHD HQ is 8-bit, which may not be ideal for projects involving a lot of compositing.

Repairit supports DNxHD, DNxHR, XF-AVC, XF-HEVC and other coding formats, and the success rate of professional coding repair has reached 91.11%. After repair, the video encoding is restored to its original state, eliminating any risk of encoding downgrading or conversion that could damage image quality.

Part 2. Where to Download the Avid DNxHD Codec?

The Avid DNxHD codec can be downloaded directly from Avid’s official website. If you’re using Avid Media Composer, the DNxHD codec is already integrated, so no separate download is needed.

Step 1: Go to the Deliver page.

Step 2: Find Custom Export and click Video under it. Next, choose the following:

• Render: Select Single Clip (for final project) or Individual Clips (for dailies).
• Format: MXF OP-Atom
• Codec: DNxHR
• Type: Choose the quality you need
• Resolution: Select the required frame size
• Frame rate: Match your source footage

Step 3: Under File, set the Filename to Source name. You can also employ the Avid AAF preset if preferred.
