HDR Image Analyzer 12G

HDR Image Analyzer 12G delivers a comprehensive array of tools for the effective analysis of up to 4x 4K/UltraHD signals, utilising both 12G-SDI and NDI connectivity.

Analyze HLG, PQ, Rec.2020, Rec.709 and native camera Log colour spaces – from 8K/UltraHD2/4K/UltraHD/2K/HD content in a powerful, real time, 1RU device. 


Developed in partnership with Colorfront, the AJA HDR Image Analyzer 12G supports a wealth of inputs from camera Log formats to SDR (Rec. 709), PQ (ST 2084), and HLG and offers Wide Color Gamut (WCG) support for BT.2020 alongside traditional BT.709 and P3, with Dolby Vision® dynamic metadata inspection and analysis for advanced HDR mastering and QC applications. AJA hardware prowess ensures high reliability and performance, with 4x 12G-SDI inputs, dual 10 GigE, and DisplayPort connections.

Specifically designed to be used wherever high performance colour analysis is needed, the 1RU form factor excels in a range of environments, providing the confidence you need for consistent and predictable HDR production and mastering.

8K/UltraHD2 Analysis

HDR Image Analyzer 12G provides the necessary connectivity to support advanced 8K/UltraHD2 HDR/WCG and SDR production monitoring and analysis workflows, including video payload identifier (VPID) analysis.

8K/UltraHD2 workflows are increasing, and so are the products that support them. Ensure your workflow gets set up correctly the first time by validating 8K/UltraHD2 VPIDs before you get started with HDR Image Analyzer 12G.

Providing the same high quality and precision analysis tools available for all other video formats, this powerful analyzer is a smart investment for today's needs as well as ensuring you are ready for tomorrow.

Dolby Vision

Supports Dolby Vision® dynamic metadata inspection and analysis for advanced HDR mastering and QC applications.

  • Display of SDI embedded Dolby Vision dynamic metadata
  • Supports both Dolby Vision v4.0 and v2.9 through automatic detection
  • Presents scene-by-scene/shot-by-shot metadata in various ways:
    • Visually in the waveform showing NIT markers for L1 metadata (Min, Mid, Max)
    • Other Dolby Vision metadata in Dolby Vision tools in human readable text

Multi-Channel Signal Analysis

Simultaneously analyze up to 4x 4K/UltraHD signals side-by-side. Perfect for camera matching and camera testing applications providing the ability to see, in real-time, the matching adjustments made.  This is also helpful for analyzing different cameras in a multi-camera environment, multiple deliverables, or even QCing multiple projects at one time.  Mix and match SDI and NDI signal analysis for ultimate flexibility.

NDI Signal Analysis

The use of Network Device Interface (NDI) is expanding into a wide range of applications from Pro AV to broadcast and postproduction applications. NDI and SDI signals are often being used within the same applications.  

New in version 3.0 is the ability to analyse and monitor NDI signals by adding NDI streams to the list of available source devices for signal analysis. NDI signals can now be analysed with the same high quality tools as your SDI signals. Applications are endless and HDR Image Analyzer 12G helps to bridge the gap between SDI and NDI workflows.

  • NDI inputs support 4K/UltraHD/2K/HD
  • Supports “Full NDI” (High Bandwidth NDI)
  • Mix and match SDI and NDI signal analysis
