A host of vendors used NAB to tout products that can convert High Dynamic Range (HDR) signals from one flavour of HDR to another, and to and from Standard Dynamic Range (SDR).

Evertz showcased new SDR to HDR conversion functionality in its 7814UDX-4K product family of Cross Converters which can be added via a software license. The update allows the device to transfer to and from SD and convert across HLG, PQ (SMPTE-2084) and S.Log3.

The license also makes it possible for the 7814UDX-4K to perform colour space conversion for BT.709, BT.2020, and S.Gamut3.

At the same time, SAM announced FormatFusion4 HDR conversion in its Kahuna production switcher line up (pictured) and support for 4K and HDR conversion in its mid-range KudosPro and UHD1000 products.

SAM Alchemist can also transfer across different HDR flavours when using file-based assets.

Sony was also discussing HDR conversion with its HDRC-4000.

The HDRC-4000 utilises original algorithms, including built-in AIR Matching (AIR refers to Artistic Intent Rendering), to reproduce the image quality and colour determined during S-Log3 production — regardless of the transmission format used.

AJA previewed the FS-HDR, a HDR workflow conversion tool that incorporates technology from Colorfront and provides HDR and Wide Colour Gamut (WCG) processing and conversion for real-time Ultra High Definition (UHD) and HD workflows. It can transfer to and from HDR and Standard Dynamic Range (SDR) and to and from different HDR variants, and includes BT.2020 to BT.709 colour space conversion.
