Beskrivelse
AJA HDR 4K/UltraHD/2K/HD Frame Sync/Converter
AJA 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.
AJA 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 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.
