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.

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.
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.
ACES Support
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 v3.0 adds an ACES Grading Colorspace and offers ACEScct Input and Output Dynamic Ranges for realtime integration with ACES workflows.

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 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.
• Upload using web GUI
• 33 point .cube format
• Store up to 10 LUTs
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, and v3.0 brings new support for Multi-Channel HD workflows, with integration support for TVLogic’s WonderLookPro and Pomfort’s LiveGrade Pro for continuous real-time LUT updates as grading is performed in third party software.
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.
HDR Workflows for UltraHD and HD with FS-HDR
FS-HDR opens a range of exciting possibilities for the integration of HDR within a range of workflows:
- Converting from a house HDR standard to a delivery HDR standard.
- Converting from a camera OETF to a house HDR standard.
- Converting from HDR standard to SDR for delivery or monitoring.
- Converting SDR camera output to a house HDR standard.
- Converting SDR sources to HDR for integrating into an HDR program.
- Converting HD SDR BT.709 sources to UltraHD HDR BT.2020.
- Converting UltraHD HDR BT.2020 sources to HD SDR BT.709.
- Converting source inputs to Sony S-Log3 S-Gamut3.
Single Channel Mode
4K/UltraHD Conversion Power with simultaneous 2K/HD outputs.
4K/UltraHD delivery, processing and synchronization is fast becoming the next standard, and FS-HDR gets you there with a wealth of digital video connectivity including Quad 1.5G, Dual 3G, Quad 3G with built in BNC connectors and 12G/6G over optional 12G-SDI HD-BNC and 12G-SDI LC Fiber SFP modules.
In single channel mode, FS-HDR will scale up your HD or SD materials to 4K/UltraHD and back, with a huge array of audio channels over Fiber, 3G-SDI, AES, and MADI for an incredible 272 x 208 matrix of audio possibilities.
In Single Channel Mode, HDR processing can be performed on true 4K or UltraHD signals and up, down, cross-conversion is available for HD HDR or HDR SDR needs from an UltraHD source.
The channel can be configured for Colorfront Engine Live mode, Colorfront Engine Film mode, BBC HLG 3D LUTs, User 3D LUTs, or Dynamic LUT mode to accomplish the desired HDR transform.
Enhanced Single Channel Mode offers simultaneous 4K/UltraHD and 2K/HD outputs for Single Master HDR workflows.
Four Channel Mode
Multi-Channel HD HDR Processing.
In Four Channel Mode FS-HDR provides incredibly powerful multi-channel conversion with up to four channels of simultaneous HDR processing for 2K/HD and SD signals. Powerful conversion processing also allows Region of Interest (ROI) scaling, color correction, proc amp controls, motion adaptive deinterlacing and much more.
Each channel can be independently configured for Colorfront Engine Live mode, Colorfront Engine Film mode, BBC HLG 3D LUTs, User 3D LUTs, or Dynamic LUT mode to accomplish the desired HDR transform.
In Four Channel Mode you can also bring in a single HD source and process four separate outputs from it, each with their own HDR/SDR transformations.
Multi-channel density in a 1RU Chassis. Space, energy and power possibilities preserved.
Incredible Digital Connectivity
Video and Audio deserve the connectivity and bandwidth required to meet the demands of your projects.
FS-HDR utilizes standard BNC as well as optional SFP inputs and outputs to integrate easily into a variety of workflows and facilities with support for SDI workflows all the way up to 12G.
FS-HDR has Coax and Fiber* inputs and outputs to accept 4K/UltraHD/2K/HD/SD resolution SDI signals in Single Channel Mode. In Four Channel Mode 2K/HD/SD inputs can be routed to multiple locations simultaneously without the need for any external signal distribution.
A looping Reference Input allows the FS-HDR to be locked to your house reference signal for rock solid stability.
Digital Audio can be disembedded and embedded between SDI, MADI and AES for an incredible array of routing possibilities
* SFP inputs and outputs are optional.
Up, Down, Cross-Conversion
Moving to 4K is never an instant change. Legacy signals and archival material need to be integrated into the 4K environment while 4K/UltraHD sources need to be down-converted for current 2K/HD pipelines.
Utilizing AJA’s remarkable conversion algorithms, FS-HDR supports up, down, cross-conversion from 2K/HD/SD to 4K or UltraHD video and back over 12G/6G/3G-SDI video. Both Square Division (SQD) and Two Sample Interleave (2SI) pixel mapping formats are supported.
AJA’s powerful hardware conversion technology ensures the highest image quality for your productions. Key conversion features include:
- 4K/UltraHD/2K/HD/SD up, down-conversion
- SD/SD aspect ratio conversion
- HD/HD cross-conversion (720p/1080i)
All done in beautiful 10-bit with dedicated hardware.
