Dolby Vision is a HDR (High Dynamic Range) format for video that provides enhanced color depth, brightness, and contrast. It was developed by Dolby Laboratories and is designed to deliver a more immersive and visually stunning viewing experience compared to traditional SDR (Standard Dynamic Range) video.
Media industry compares Dolby Vision and HDR10. The main difference between Dolby Vision and HDR10 is the colour depth and brightness the content and equipment is capable of achieving. Dolby Vision content is mastered up to 12-bit colour depth, compared to HDR10's 10-bit (which is where HDR10 gets its name from).
Dolby Vision uses metadata to adjust the brightness, contrast, and color of each frame in real-time, to ensure that the image is displayed exactly as the filmmaker intended. This results in a more vivid and lifelike image, with deep blacks and bright highlights, and a wider range of colors that are closer to what the human eye can see.
Dolby Vision is supported by a range of devices, including TVs, Blu-ray players, streaming devices, and home theater systems. It is also supported by many major streaming services, including Netflix, Amazon Prime Video, and Disney+.
In addition to its technical advantages, Dolby Vision is also designed to be easy for filmmakers to use. It provides a comprehensive set of tools and resources for color grading and post-production, allowing filmmakers to bring their creative vision to life in a way that was previously not possible with traditional SDR video.
Some of the key OEMs that support Dolby Vision are LG, Panasonic, Philips, TCL, Hisense. This is not an exhaustive list and you can check with your OEM provider for the support of Dolby Vision. You may wonder why Samsung is not on list. The reason is that Samsung supports rival format i.e. HDR10+
