AJA Release Control Link Software

AJA Release Control Link software v1.3.0 for FS-HDR

Control Link Software v1.3 is control software for utilising a Tangent kb panel alongside a FS-HDR for tactile control of the FS-HDR's Colorfront Engine-Live parameters.

Control of the FS-HDR Colorfront Engine-Film and TV Mode parameters will be supported in a future release.

v1.3 adds PQ Output NIT Level and P3 Colorspace Clamp controls for Colorfront Engine-Live and fixes an issue with Saturation parameter default values.

If you are using an FS-HDR version before 3.0 please use the v1.1 version of the Control Link software.

Please read the FS-HDR Release Notes and see the FS-HDR manual for instructions on using this software alongside the FS-HDR with a Tangent kb panel.

FS HDR Overview

FS-HDR, a 1RU, rack mount, universal converter/frame synchroniser, 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.

FS-HDR Colorfront Engine TV Mode

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 colours 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.
