Enhanced Dolby Vision 2: Utilizing Metadata to Minimize Jittery Image Appearance
In the world of high-definition television, the pursuit of a seamless viewing experience continues. Two significant developments have emerged recently, with Dolby Vision 2 and the introduction of the Authentic Motion feature.
Dolby Vision 2, an update to the existing Dolby Vision standard, is not a radical departure but rather an enhancement. The basic set of metadata for Dolby Vision has remained unchanged, but extensions in HDR playback focus on topics such as maintaining a TV image that is not too dark in any environment, improved ambient light recognition, and optimization of playback for gaming and sports.
The "Authentic Motion" option, offered through the Dolby Vision 2 HDR technology, is designed to reduce judder and make scenes feel more authentically cinematic shot-by-shot. This feature is being introduced primarily by Hisense, making it the first TV manufacturer to integrate Dolby Vision 2 into its higher-end models.
Judder, a noticeable stutter in the movement of objects on screen, can be more pronounced on larger TV screens and bright projections due to movements traveling longer across the screen. Smaller displays, on the other hand, often make judder less noticeable because movements cover less distance. HDR displays, with their higher base luminance, can also make judder more noticeable.
TV manufacturers address judder with algorithms for motion compensation, such as Digital Natural Motion, Active Motion, TruMotion, Motionflow, or AI Motion Enhancer. However, these algorithms can create an effect similar to a low-budget video production, often referred to as the "soap opera" or "soap" effect. The strength of motion compensation is usually adjustable in several stages, and its use is divisive among viewers.
Dolby Vision-capable TVs that are still on the old standard can play DV2 content, but without the new features. For those seeking more information on this topic, resources can be found on the ct 3003 website, our website, and Peertube.
Dolby Vision, a dynamic HDR format, has been around for over ten years, and its latest update, Dolby Vision 2, promises to elevate the viewing experience further. Whether you prefer the natural motion of standard settings or the smoothness of enhanced motion compensation, the choice is now more diverse than ever.
