Sony White Paper: What is SR Live for HDR?

The use of High Dynamic Range (HDR) technologies for live production applications represents a new and exciting technical challenge, comparable to other fundamental innovations in the history of content creation for live television. A key challenge has been the addition of 4K HDR production techniques to the existing HD live production environment while simultaneously maintaining the skill sets and workflows required to support the creation of content for the current HD marketplace.

In order to find solutions to these issues Sony has carried out extensive technical research and HDR trials with broadcast and production communities. One of the results has been a free white paper containing detailed information on:

  • Production workflows for the simultaneous creation of 4K HDR and HD SDR programmes
  • Execution of camera shading and/or painting on the HD SDR domain
  • Simultaneous production for both 4K HDR and HD SDR S-Log3 as intermediate production format
  • Look orientated OOTF
  • Characteristics of S-Log3 as Intermediate Production Format
  • Utilisation of HDRC-4000
