Key Takeaways
- HDR and Dolby Vision are two main HDR formats that offer better picture quality than standard dynamic range.
- HDR10 is a free and open-standard format that uses static metadata and supports up to 4,000 nits peak brightness.
- Dolby Vision requires a license and fee, uses dynamic metadata, and supports up to 10,000 nits peak brightness.
- Dolby Vision currently produces better image quality than HDR10 due to its dynamic metadata.
- However, there are no TVs that can fully take advantage of Dolby Vision compared to HDR10.
Understanding HDR and Dolby Vision
HDR (High Dynamic Range) and Dolby Vision are both technologies that enhance the viewing experience by providing a wider range of colors and contrast than standard dynamic range (SDR). HDR is an open standard that is supported by a wide range of devices, while Dolby Vision is a proprietary technology that is only supported by certain devices.
HDR
HDR is an open standard that is supported by a wide range of devices, including TVs, monitors, and smartphones. It uses static metadata that applies to the entire movie or show, which means that the HDR "look" is determined per movie or show.
HDR10 is a specific implementation of HDR that is free and open-standard.
It supports up to 4,000 nits peak brightness, with a current 1,000 nit peak brightness target.
HDR10 can be mastered anywhere up to 4,000 cd/m², depending on the content, but it doesn't have a minimum brightness.
Dolby Vision
Dolby Vision is a proprietary technology that is only supported by certain devices, such as some LG OLED TVs and LCDs from Vizio and TCL. It requires a license and fee from Dolby. Dolby Vision uses dynamic metadata, which can adapt the picture's light/dark values either in scene-to-scene or frame-by-frame, carrying instructions to the TV to tell it how bright or dark it should be at any given moment.
This dynamic metadata improves contrast, detail, and color reproduction.
Dolby Vision supports up to 10,000 nits peak brightness, with a current 4,000 nit peak brightness.
It is currently capable of producing better image quality than HDR10, mainly due to its dynamic metadata.
Which is Better: HDR or Dolby Vision?
In terms of which is better, it ultimately depends on personal preference and the specific devices being used. HDR is an open standard supported by a wide range of devices, making it more widely compatible.
On the other hand, Dolby Vision offers more advanced features, such as dynamic metadata, which can result in a more accurate and consistent viewing experience.
Some people may prefer the wider compatibility of HDR, as it can be enjoyed on various devices. HDR10, being an open standard, is supported by a wide range of TVs, monitors, and smartphones. This means that users can experience HDR content without the need for specific devices or licenses.
On the other hand, Dolby Vision provides a more advanced and refined viewing experience. Its dynamic metadata allows for scene-by-scene adjustments, resulting in more accurate color reproduction and contrast.
However, Dolby Vision requires a license and fee from Dolby, and there are currently no TVs that can take full advantage of what it provides compared to HDR10.
Summary
HDR and Dolby Vision are technologies that improve the viewing experience by providing a wide range of colors and contrast. HDR is an open standard supported by a wide range of devices, while Dolby Vision is a proprietary technology supported only by certain devices.
Dolby Vision uses dynamic metadata that can adjust the color and contrast on a scene-by-scene basis, which can result in a more accurate and consistent viewing experience.
Which one is better depends on personal preference and the specific devices being used.
HDR10 and Dolby Vision are two different HDR formats that are used in modern TVs and monitors. The main difference between the two is that HDR10 is an open-standard and non-proprietary, while Dolby Vision requires a license and fee from Dolby.
Dolby Vision is capable of producing better image quality than HDR10 due to its dynamic metadata, which can change information such as color and brightness dynamically on a frame-by-frame basis.
However, there are currently no TVs that can take full advantage of what Dolby Vision provides as opposed to HDR10.
