and Dolby Vision raise the bar Imaging Glossary
Dolby Vision widens your luminance to give more details in the darks...
...and widens the colour spectrum to give more nuances to your palette
Image Resolution Resolution is sometimes identified by the width and height of the image as well as the total number of pixels in the image. HD is the current standard for high quality images used by broadcasters and online providers. 4K/ Ultra HD in the home, 4K resolution, also called UHD, is 3840 x 2160 pixels – four times the detail of HD. Available in the cinema and at home, High Dynamic Range (HDR) technology is used to produce brighter and sharper images on screen, providing more detail in darker areas of the picture.
Nits: A measurement of how much light the screen sends to your eyes (luminance) within a given area.
Bit depth: A measurement that quantifies how many unique colours are available in an image’s colour palette.
Wider colour gamut: Often referred to as spectrum, this is the ability to showcase more colours
than has previously been possible. The human eye can see far more colours than current screens can display. With Dolby Vision, we widen the colour spectrum, so we can recreate richer, deeper colours on screen.
HDR10: The base layer for UltraHD which supports 10-bit and static metadata. Dolby Vision HDR includes an enhanced layer which adds 12-bit and dynamic metadata to display more accurate images.

Dolby Vision Dolby Vision
Key Benefits • Astonishing brightness • Deep darks • Expanded contrast • Ultravivid colours • Refined details
• Enhanced dimensionality • Wider colour gamut • Biggest creative space, no limits on possibilities in HDR
Dolby Vision delivers a dramatically more dynamic visual experience - astonishing brightness, incomparable contrast, and captivating colour. It achieves this stunning image quality through innovative high-dynamic range (HDR) and wide colour gamut imaging technologies.
As a result, it makes every pixel better, enabling televisions to deliver images with much greater brightness while providing much deeper, more nuanced darks. It renders a fuller palette To ensure a wide adoption of Dolby Vision among consumers, Dolby has worked with manufacturers across all screens: television sets, laptops, tablets and mobile phones. Dolby Vision has been rapidly adopted by big brands such as LG, Panasonic and Toshiba, and is available across most of their range and price points.
Workflows and Deliverables
Dolby has worked hand in hand with the main stakeholders in the film and broadcast industry to develop the most efficient and agile workflows for Dolby Atmos and Dolby Vision. Content is sold in phases to various distribution channels and it can be costly to have to go back to post-production to create new deliverables.
By following our recommended process, you ensure you can
create all the required deliverables from the Dolby Vision and Dolby Atmos masters and produce all the formats required by all broadcasters and digital platforms worldwide. Netflix, Apple TV, Disney+ all request content in Dolby Atmos and Dolby Vision. This ensures that your deliverables will be future- proof and your content will have a longer shelf life in the best possible quality.
Dolby Atmos Workflow • Prepare your editing in Dolby Atmos
• Mix in Dolby Atmos • Render your Dolby Atmos mix in Dolby 7.1, Dolby 5.1, and stereo
• Your 7.1, 5.1, and stereo sound better
• One master for four audio deliverables
Dolby Vision Workflow • Grade HDR first with Dolby Vision
• Perform a Dolby Vision analysis • Review and trim SDR using Dolby Vision tools
• Improve the quality of your SDR grade
• One master for 4 imaging deliverables (Dolby Vision, HDR10, SDR, HLG)
