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.
HDR captures subtle expressions of light and shadow to amplify the imagination of every storyteller.
All our latest CineAlta cameras including the acclaimed VENICE are HDR ready, supporting the efficient X-OCN format with our AXS-R7 portable memory recorder.
Shooting in X-OCN allows 16-bit scene linear tonal gradation, retaining the camera’s full dynamic range and affording greater capacity for visual expression with dramatically smaller file sizes.

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 in the section, “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 White 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.
SR Live MetaFile
The HDRC-4000 HDR converter unit performs HDR to SDR / SDR to HDR conversions within Sony’s SR Live production workflow.
The parameter settings for each conversion, including SR Live Metadata, can be saved within the HDRC-4000 or stored on an external USB memory as an SR Live MetaFile (.srm) file.
The SRM files can be shared between multiple devices using the file transfer function of an MSU (Master Set-Up Unit) or via the USB memory storage. The files can be used to store a production team’s preferred conversion parameters, or to apply a pre-set value for each parameter.
Preset SR Live MetaFiles and SR Live 3D LUTs
In SR Live, picture painting is based on the customer’s preference, but it could also be used for trials for set-up and easier, more convenient settings by determining the standard value of setting. For such purposes, Sony has provided a selection of pre-set SRM files that have been optimised for use within an SR Live workflow. They can be used for the efficient configuration of equipment for a real-world production, or as the basis of a workflow test prior to a live event.
There are two (2) kinds of SRM files have been provided. One is called “Standard Setting”, and the other one is “Versatile Setting”. Users can select either a “Standard” or a choice of “Versatile” settings. The “Standard” is fixed and primarily intending to derive a conventional look of SDR images, while the “Versatile” settings provide a degree of control over the dispersion of brightness in the HDR signal.
HDR signals can be displayed smoothly even when mixing image signals that have different criteria for brightness as it is possible to express wide luminance signals.
On the other hand, with SDR signals, the luminance level must be strictly controlled.
For this reason, when converting HDR signal to SDR signal, Gain setting decisions for HDR to SDR conversion can be more challenging especially when an input signal is painted/shaded in HDR domain that has a different brightness managing criteria.
To address this challenge, versatile SR Live setting value that can maintain certain SDR image quality can be provided as a “Versatile Setting” SRM file.
Sony has also created a set of 3D-LUT (.cube) files for use in HDR to SDR / SDR to HDR conversion equipment within an SR Live workflow.
The SR Live 3D-LUT files can be used within an HDR production chain to convert a program output from HDR to SDR, or when assessing image quality using an SDR picture monitor.
As same as the set of SRM files, users can select either a “Standard” or a choice of “Versatile” conversion quality. The “Versatile” settings provide a degree of control over the dispersion of brightness in the HDR signal.
