HDR10+ Technologies explains that dynamic metadata is generated automatically during the color grading process via statistical analysis of luminance characteristics, rather than through manual authoring. The article also highlights the HDR Dual Carry capability, which allows for the simultaneous transmission of SMPTE ST 2094-40 and ST 2094-10 metadata tracks in broadcast environments.
The automated nature of this metadata generation removes the financial and operational friction typically associated with high-dynamic-range mastering. By making the enhancement a byproduct of the standard grading suite rather than a bespoke manual step, the ecosystem can support a higher volume of content across diverse distribution channels like UHD Blu-ray and OTT streaming. This technical efficiency explains the format's adoption by over 180 companies, as it allows for consistent creative intent without doubling post-production timelines. Watch for further expansion of the Dual Carry standard in terrestrial broadcast as more station groups follow Gray Television's lead in deploying ATSC 3.0 infrastructure.
HDR10+ dynamic metadata is now derived automatically through statistical luminance analysis during color grading and transcoding. This process eliminates the need for manual authoring, allowing HDR content to scale across professional, live, and mobile workflows. By removing production friction, this technical efficiency supports consistent creative intent across diverse distribution channels.
It is derived automatically from colorist decisions using mastering software that analyzes scene-by-scene luminance characteristics during the grading and transcoding process.
HDR Dual Carry is a specification that enables the simultaneous transmission of SMPTE ST 2094-40 and ST 2094-10 tracks within a single encode, which is currently being used for ATSC 3.0 rollouts.
It removes the financial and operational friction of manual mastering, allowing platforms to support a higher volume of HDR content across OTT and broadcast without increasing production timelines.
Gray Television has implemented the Dual Carry standard for its ATSC 3.0 rollout across more than 40 U.S. markets.
