FS-HDR, a 1RU, rackmount, universal converter/frame synchronizer, is designed specifically to meet the High Dynamic Range (HDR) and Wide Color Gamut (WCG) needs of broadcast, OTT, production, post, and live event AV environments, where real time, low latency processing and color 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.
In Single Channel Mode, FS-HDR also serves as a full, 1-Channel up, down, cross-converter for 4K/UltraHD/2K/HD HDR transformation. In 4-Channel Mode, FS-HDR offers 4 independent channels of 2K/HD HDR/WCG transformations as well as up, down, and cross conversions.
TV Mode is a new operational mode that provides a simple to use transform selection interface with minimal controls required for live television production. It addresses color correction and camera correction while adding two new controls essential for HDR/SDR transforms. These new controls are for Knee Point and Knee Slope and they help to manage highlights and roll-off in HDR to SDR and HDR to SDR conversions. They also improve the quality of the SDR output by using more of the information available in the HDR program. Shouldn’t your SDR deliverable benefit from all the effort put into your HDR production?
The Colorfront Engine uses conversion algorithms based on the human visual system that provide better SDR to HDR color transformation as well, improving the overall look of SDR sources used in your HDR production. To protect and maintain color fidelity of SDR brand colors used in graphics or in-camera, the combination of SDR to HLG and HLG to SDR transforms using the Colorfront Engine TV Mode provides the necessary “round-tripping” capabilities.
A perceptual transform integrates the various human perceptual phenomena into a model or perceptually linear transform space. Unique to the FS-HDR Colorfront Engine TV Mode, transforms are calculated in this perceptual space. Dynamic range, surround illumination, color volume, perceived saturation, and perceived hue are accounted for.

Up and Down Conversions:
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 enable 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.
Colorfront Engine TV Mode provides specific conversions and simplified controls for highlight and roll-off management in live television broadcast productions.
Colorfront Engine Live Mode provides conversions and controls that support live applications such as broadcast, OTT, A/V, and venue.
Colorfront Engine Film Mode provides conversions and controls, including ASC CDL, for applications such as on-set camera preview and look creation.
FS-HDR provides parametric controls for Colorfront Engine’s HDR transforms and color correction in Live, TV and Film Modes. 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.
Colorfront Engine parametric controls enable the following:
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.
The Academy Color Encoding System (ACES) is becoming an industry standard for managing color throughout the life cycle of a motion picture or television production. From capture through editing, VFX, mastering, public presentation, archiving, and future remastering, ACES ensures a consistent color experience that preserves the creative vision.
FS-HDR offers an ACES Grading Color Space with ACEScct Input and Output Dynamic Ranges for real time integration with ACES workflows.
Colorfront Engine in Film Mode offers built-in LOOK selection including film stock emulation and popular aesthetic looks, valuable tools for on-set and episodic production and you can even mix between any two for unique specific aesthetic needs:
BBC HLG LUTs Mode offers additional functionality that adds HDR conversion options, particularly for television broadcasters who are looking for specific conversion criteria.
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 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.
FS-HDR also supports Dynamic LUT uploads from 3rd party software for live playout, with the ability to see changes as you implement them.
Single Channel Dynamic LUTs support 4K resolutions while Four Channel Mode supports Multi-Channel HD workflows, with integration support for TVLogic’s WonderLookPro and Pomfort’s LiveGrade Pro grading software for continuous real time LUT updates.
Dynamic LUT support for both Single Channel and Multi-Channel workflows

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.
FS-HDR opens a range of exciting possibilities for the integration of HDR within a range of workflows:
