5 steps to your ideal HDR and SDR version

In each production the data to be delivered and the best possible quality of your work play the central role. Currently, groundbreaking new formats and quality levels of film that revolutionise the film experience are already in the door, such as dynamic HDR and UHD.

Storytelling redefined

Optimised SDR and the best dynamic HDR experience with the Dolby Vision workflow

High Dynamic Range (HDR) in particular provides an image reproduction that is even closer to reality by combining the high contrast images with an extended colour space. These can already be output dynamically – sequence by sequence – and optimised for each end device. This is as significant a change as the transition from SD to HD and from black and white to colour. This heralds a new era in cinematic storytelling.

At the same time, SDR versions are still essential for standard transmission. Therefore an efficient and flexible workflow is mandatory for every production.

1. Workflow coordination

Already in the run-up the effort and the costs involved in post production and mastering can be significantly minimized. By coordinating the camera sytems used, the recording format and the editing technology, we can provide you with advice before the start of production so that nothing stands in the way of the data to be delivered.

2. Editing

When editing the film in post production, proxy material can be used to save resources. After the picture lock, the material is then further processed by us. The editing of the film does not necessarily have to be done on Magenta TV.

Flexibility and technology:

Of course, you can also benefit from our infrastructure already during the editing. Just book one of our edit suites and bring your favourite editor with you if you wish. Central, synchronized working, short distances between color correction and sound studio as well as a render farm for encoding are at your disposal.

3. bringing online

Here, for example, the RAW data is made available online via our AVID editing system.  

Depending on the source material, this can take between one day and two weeks. In order to avoid longer processing times, it is advisable to coordinate the process in advance (see Step 1 – Workflow coordination).

The material is then sent to our colorists for color grading.

4. HDR Master and Color Grading

Dolby-Vision HDR color correction is similar to the existing color grading workflow. The goal is to preserve more of what the original camera captured and limit creative compromises.

We work in the Nucoda FilmMaster in PQ at a defined peak luminance of 1000 Nits and in the color space based on the human visual perception system. For this we use the Dolby Vision compliant reference monitor “Sony BVM X300”, which also achieves high brightness levels and a wide colour space.

From this the HDR master will be created first, which does not yet contain any dynamic metadata. Our system then uses the Dolby-Vision algorithm to analyze the master grade and stores the obtained metadata.

The content is mapped for SDR at 100 Nits via a Dolby Engine and we then perform the “Trim Pass”. Attention: Since there are different DolbyVision models which are conditionally compatible, please coordinate the workflow in advance (step 1).

The HDR PQ master and the SDR master for the standard broadcast workflow will be finally rendered.  Now you have the clean files as a starting point for further processing.

In the following and final step the credits, title, sound, graphics and/or subtitles are now assembled in our AVID editing system.

5. Finishing / Dolby Vision package

The entitled HDR material is re-analysed.
Another advantage of the DolbyVision workflow on Magenta TV, besides the optimized SDR version, is the easy creation of versions of your film with different titles in different languages and/or dubbed versions.

The trim data of the Dolby Vision workflow is used by the Clean HDR PQ Master from step 4. It is checked whether further adjustments are necessary.

The dynamic metadata is exported and a Dolby Mezzanine HDR PQ is rendered out. This provides you with the titled versions for a generic HDR PQ and the dynamic Dolby Vision mezzanine.

All about HDR

Would you like background information and to find out more about HDR, the formats and their differences? Then simply read our article “What you need to know about HDR as a film maker”.


For directors, producers and other filmmakers, the dynamic HDR offers enormous new possibilities to narrate the story. This can be done sequence by sequence as well as cross-platform.

The Dolby Vision workflow offers a very efficient way to make your work available for both dynamic HDR and optimized for SDR. Furthermore, different titled and/or synchronized versions can be created with a moderate amount of work.
