FS-HDR, a 1RU, rackmount, universal converter/frame synchronizer, is designed specifically to meet the High Dynamic Range (HDR) and Wide Colour Gamut (WCG) needs of broadcast, OTT, production, post and live event AV environments, where real time, low latency processing and colour fidelity is required for 4K/UltraHD and 2K/HD workflows. Developed in partnership with Colorfront, the FS-HDR’s HDR/WCG functionality is powered by Colorfront Engine proprietary video processing algorithms.

FS-HDR also serves as a full, 1-Channel up, down, cross-converter for 4K/UltraHD/2K/HD HDR transformation, conversion and frame sync needs and in 4-Channel mode, offers 4 independent channels of 2K/HD conversion including HDR transformations.

FS-HDR for Real Time HDR Workflows

Deliver more immersive content to audiences with the power and flexibility of AJA FS-HDR. See how FS-HDR and the Colorfront Engine can simplify real time HDR/WCG transformations, and make it easy to maintain the look you’ve worked to achieve across SDR to HDR, HDR to HDR and HDR to SDR for both 4K and HD needs.

Real Time HDR Converter

The pursuit of High Dynamic Range (HDR) is the dream of getting closer to the Human Visual System (HVS) in all that we experience as viewers. FS-HDR has been designed to get us all there faster with a low profile, stand-alone and real time device uniquely designed to bridge SDR to HDR, HDR to SDR and HDR to HDR, all in real time. 

HDR Conversions:

  • HDR to HDR
  • HDR to SDR
  • SDR to HDR

WCG Conversions:

  • BT.709 and BT.2020

Up and Down Conversions:

  • Converting HD SDR BT.709 sources to UltraHD HDR BT.2020
  • Converting UltraHD HDR BT.2020 sources to HD SDR BT.709 or HD HDR BT.2020

Colorfront Engine™

Maintaining Perceptual Integrity

FS-HDR’s HDR/WCG capabilities leverage video and color space processing algorithms within the Colorfront Engine™,  specially licensed by AJA from Colorfront, and developed by Colorfront’s CTO Bill Feighter and Lead Engineer Tamas Perlaki.

Powered by the Colorfront Engine, FS-HDR’s extensive HDR and WCG processing support enables real time processing of a single channel of 4K/UltraHD/2K/HD including down-conversion to HD HDR  or up to four channels of 2K/HD simultaneously.  FS-HDR also enables the conversion of popular camera formats from multiple vendors into the HDR space, plus conversion to and from BT.2020/BT.709 as needed, critical for the widespread acceptance of HDR alongside SDR in broadcast and OTT workflows.

Real Time Camera LOG Conversions

FS-HDR can take incoming imagery from some of the most popular professional cameras in the world today and convert their LOG output in real time to 4K/UltraHD or 2K/HD and output as either HDR or SDR. This greatly simplifies workflows in a mixed camera environment and provides for a unified input workflow to HDR or SDR capable switchers and more. Additionally, FS-HDR provides the ability to convert to Sony S-Log3 S-Gamut on output from any of these sources for workflows requiring this Log feed to compatible switchers and more.

3D LUT Uploads and Dynamic LUT Support

3D LUTs place color and luma in a 3D space, a much more representative way of how color works in the real world and useful for capturing and relaying more complex color grades than 1D LUTs.

FS-HDR v2.6 supports uploads of user created 3D LUTs (33 point .cube format), with the ability to store and recall as needed through the FS-HDR's simple visual GUI. This is ideal for bringing a standard desired look to a production, applying a creative LUT previously designed for the sake of the project or potentially loading a film emulation LUT for a particular look.

Additionally FS-HDR now supports Dynamic LUT uploads from 3rd party software for live playout with the ability to see changes as you implement them. Support is available now for TV logic WonderLookPro and soon for Pomfort LiveGrade Pro. 

  • Upload using web GUI
  • 33 point .cube format
  • Store up to 10 LUTs

Parametric Controls for HDR Transforms and Colour Correction

FS-HDR provides 21 parametric controls for Colorfront Engine FS-HDR HDR transforms and color correction. Each parametric control is accessible via FS-HDR’s front panel, the web GUI on any browser, or REST interface, and settings can be stored to a preset for recall later or copied to other FS-HDR units. 

Twenty one individual parametric controls enable the following:

  • Adjusting R,G,B, and Master color controls for Lift, Gamma, and Gain
  • Adjusting Saturation
  • Guiding the algorithm’s colour volume expansion from SDR to HDR
  • Adjusting for the Ambient Light in the mastering or viewing environment
  • Managing how SDR highlights and speculars are expanded into HDR
  • Controlling the overall look of camera log inputs between cinematic and television
  • Support for ITU BT.2408-0, Operational Practices in HDR Television Production.

SDR Preview Mode

The Colorfront Engine SDR Preview Mode allows a user to quickly see what an HDR output will look like if it were converted to SDR by an FS-HDR.  This is extremely useful in functions like camera shading, where the operator is making adjustments to an HDR camera while viewing the image on an HDR display.  A key question is "what will this picture look like when down converted to SDR?"  The FS-HDR's unique SDR Preview mode provides a fast way to answer this question without requiring an HDR to SDR equipment chain or reconfiguring the existing HDR monitor. 

When SDR Preview is enabled, the Colorfront Engine maps the video into the currently selected HDR space (PQ or HLG), but with values that will exactly represent the SDR image.  This eliminates the time normally required to change the output format to SDR and the wait for the display to reconfigure.  By simply controlling the on/off state of SDR Preview (from the front panel, Web GUI, or GPI), the operator can make quick, glitch free A/B comparisons of the HDR and SDR images.
