AJA Video Systems has announced free v4.0 firmware for the FS-HDR real-time HDR/WCG converter and frame synchronizer featuring a new Colorfront Engine TV Mode, v1.4 BBC HLG LUTs, and more.

The Colorfront Engine TV Mode provides new colour and camera correction essentials, adding Knee Point and Knee Slope controls to better manage highlights and roll-off in SDR and HDR (HLG and PQ) conversions, greatly enhancing the image output. With this mode, more HDRimage information is accessible for use in SDR down-conversions, and SDR expansion into HDR can be more thoughtfully managed. The new mode is powered by an algorithm based on the human visual system that maintains the source colour relationships of the original material though the transform process. To protect the colour fidelity of SDR brand colours used in graphics or in-camera, SDR to HDR and HDR to SDR transforms facilitate seamless round-tripping.

For users looking to take advantage of the latest BBC HLG LUT improvements, FS-HDR v4.0 also includes new v1.4 BBC HLG LUTs and a new LUT 9 for HLG to SDR display-light conversions. Additional enhancements include support for a wider range of camera metadata management schemes to streamline the pass-through of camera and lens metadata through FS-HDR to downstream devices for on-set applications, and the ability to configure the HDR components of the SDI output VPID on a channel-by-channel basis, which has proven vital to workflows that require a consistent VPID.

“HDR production is in a constant state of change. As more HDR workflows are implemented, we’re working alongside customers in the field, taking notes and envisioning new features we can build into firmware releases like v4.0. We’re excited to bring FS-HDR users powerful new features that will simplify their day-to-day production challenges,” said Nick Rashby, President, AJA Video Systems.
