AJA FS-HDR Universal Converter/Frame Synchronizer

AJA FS-HDR HDR/WCG Converter/Frame Synchronizer

AJA FS-HDR is a powerful universal converter/frame synchronizer 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 the Colorfront Engine™ proprietary video processing algorithms.

In Single Channel Mode, FS-HDR also serves as a full, 1-channel up, down, cross-converter for up to 4K/UltraHD HDR/WCG transformations. In 4-Channel Mode, FS-HDR offers four independent channels of 2K/HD HDR/WCG transformations, with both modes providing up, down, and cross conversions, and high-quality frame syncing, all in a slim, 1RU rackmount form factor.

Colorfront Engine

FS-HDR’s HDR/WCG capabilities leverage video and color space processing algorithms within the Colorfront Engine, especially 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. TV Mode and Live Mode are also offered in AJA’s ColorBox.

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 Colorfront Engine TV Mode

TV Mode is an operational mode that provides a simple-to-use transform selection interface with minimal controls required for a live television production. It addresses color correction and camera correction while introducing new controls essential for HDR/SDR transforms, including Sony S-Log3. These new controls for Brightness, Highlight, Super Highlight, and Colorfulness are designed to enable operators to produce high-quality SDR and HDR video by processing within the guardrails of Colorfront’s perceptual processing algorithm, which will maintain perceived color, hue, and saturation without hard clipping artifacts and maintaining proper color relationships. These controls help manage highlights and roll-off in HDR to SDR conversions. They also improve the quality of the SDR output by using more of the information available in the HDR source.

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.

Configurable Frame Delay

FS-HDR offers the largest configurable frame delay in its class of up to 20 frames per channel, ensuring all sources stay on time.

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.
