High Dynamic Range (HDR) offers broadcasters and content creators limitless expressive possibilities.
Sony Professional HDR can offer the solutions you need to create visually stunning HDR images, for any production.
From cinematography and TV broadcasting to live events and corporate videos, we’ll help realise your vision with a comprehensive portfolio of hardware, recording formats and workflow options – from acquisition to post-production and mastering.
The choice of industry leading broadcasters, production houses and OB Truck Companies around the world, SR Live for HDR offers these compelling benefits:
• Realisation of a Scene Referred HDR production workflow
• Simultaneous creation of both HDR and SDR programme content
• SDR-based camera shading using existing tools and techniques
• ‘As-seen’ conversion, to maintain creative intent throughout the production and delivery chain
In an SR Live production workflow, it is recommended that 4K HDR is used as the principal production format, allowing conversion to any format required for distribution. During shooting, the Video Engineer can perform simultaneous production of 4K HDR/HD SDR by adjusting the HD SDR output as described at, “SDR-based camera shading”, below. This eliminates the need for a dedicated crew for HDR adjustment and enables efficient operation that follows the conventional HD production workflow.
These are the summarised key features of Sony SR Live – more detailed information is available in our latest Whitle Paper, downloadable at the link on this page.
HDRC-4000 – the foundation of SR Live production
The HDRC-4000 can support a wide variety of video signal conversion, including 4K HDR, HD HDR, 4K SDR and HD SDR – without signal loss and while achieving greater workflow efficiency.
Importantly, this means that the same picture tone after conversion between 4K HDR to another 4K HDR format, is retained. It is also possible to achieve the same HD SDR image matching after 4K HDR to HD SDR conversion has taken place, at later stage in the production process.
AIR Matching function
The HDRC-4000 can also provide “as seen” conversion of the AIR Matching function to faithfully retain the producer’s artistic intent, across any distribution format, throughout conversion.
SDR-based camera shading
While SDR remains prevalent, broadcasters and production houses must avoid degradation of the SDR production workflow – even if they’re producing in HDR at the same time. With SDR-based shading, camera operators (shaders/painters) can continue using their knowledge of picture quality in SDR production for both SDR and HDR images.
SR Live Metadata
Sony’s recently introduced SR Live Metadata packet stores 26 parameters, describing creative decisions and camera adjustments made by camera operators during production. Embedded within the SDI signal, this metadata provides information to allow exact duplication of the SDR programme from the HDR layer. This is available even if conversion from HDR to SDR takes place at a later stage in the production process at the broadcast station. It also allows metadata parameters to be checked visually, both live and during post-production.
