HDR10+ ADVANCED FAQ

HDR10+ ADVANCED is the next evolution of the HDR10+ standard, introducing enhanced dynamic metadata to improve brightness, color, motion handling, and scene-specific optimization for a more immersive viewing experience.

HDR10+ ADVANCED content can carry an optional layer of scene-level description called Content Descriptive Metadata. It works in two parts: a genre classification (Movie, Sports, Animation, News, or General) and a set of scene attribute tags that can be combined to describe the characteristics of each specific scene.

The attribute tags cover a wide range of visual properties:  lighting environment (outdoor daylight, indoor LED, low-light, etc.), motion characteristics (fast object motion, slow-paced replay, etc.), camera perspective (wide-angle, close-up, aerial/drone, etc.), and more. Multiple tags can be applied to a single scene simultaneously, allowing precise description;  for example, a soccer match scene might combine Sports + Field Sports + Fast Object Motion + Outdoor Daylight + Panning all at once.

Displays that support HDR10+ ADVANCED can read these tags to inform and optimize their image processing for each scene. The tag system is extensible by design: HDR10+ Technologies, LLC coordinates the definition of new tags as content providers, display manufacturers, and creators collaborate to develop additional scene descriptors that benefit future AI-assisted image processing.

HDR10+ ADVANCED’s genre-based optimization allows displays to automatically tailor picture settings—via tone mapping, color, and motion processing—to broad content types like movies, sports, or documentaries.  It also supports sub-genres, enabling finer adjustments (e.g., lighting type vs. landscape details in golf) for a viewing experience that better aligns with the content.

Standard (global) tone mapping applies a single brightness curve across the entire frame. This works well for most content, but can struggle when a scene contains both very bright highlights and very dark shadow areas simultaneously; the compromise curve required to handle the extremes can crush detail in either direction.

Local Tone Mapping in HDR10+ ADVANCED allows content providers to define specific regions of the frame, circular, elliptical, or rectangular, where tone mapping should be applied differently from the rest of the image. Each defined region carries its own distribution values, allowing the display to tone map that area independently. The result is that a bright, practical light source in the corner of a dark scene, or a sunlit window in an otherwise shadowed room, can be rendered with full detail in both regions simultaneously.

Local Tone Mapping metadata can be defined by the content creator within their color grading suite during the color process, or generated automatically.

Judder, the characteristic stutter of 24fps film,  is intentional. Filmmakers rely on it as part of the cinematic aesthetic. The problem is that as home displays get larger and brighter, judder becomes more noticeable and potentially distracting, so displays have historically applied their own motion smoothing globally, overriding the filmmaker’s intent in the process.

HDR10+ ADVANCED Intelligent Motion Smoothing addresses this by embedding the content provider’s motion intent directly into the video metadata, scene by scene. Rather than leaving smoothing decisions entirely to the display, the metadata communicates the creative latitude the content provider is permitting — on a scale from no smoothing at all (preserving the original cinematic cadence) through to full smoothing. At the maximum setting, the content provider is signalling that smooth motion is the priority for that scene — appropriate for sports, fast action, or scenes where motion characteristics that were imperceptible in a darkened cinema at reference brightness become more apparent on today’s larger, brighter home displays. The display reads this signal and applies motion processing within those bounds, taking into account the viewing environment and the display’s own characteristics.

The reference point is the cinema experience at 14 foot-lamberts — the standard cinema brightness at which filmmakers intend their content to be experienced. HDR10+ ADVANCED Motion Smoothing is designed to help certified displays replicate that intended motion experience, even as real-world viewing conditions vary.

The motion smoothing metadata can be generated automatically at content encoding or set manually by content providers, giving studios full control when they want it and an efficient automatic path when they don’t.

HDR10+ ADVANCED supports video up to 16-bit color depth and brightness levels up to 10,000 nits, providing full backward and forward compatibility.  This ensures the format is future-ready for next-generation displays, while maintaining optimal image quality across current hardware.

Yes. HDR10+ ADVANCED includes Adaptive Cloud Gaming that uses real-time ambient light data and dynamic tone mapping to optimize visibility and immersion with cloud-based games, using compatible HDR10+ GAMING platforms. HDR10+ ADVANCED is the 2025 specification that introduced the Adaptive features for gaming.

HDR10+ ADVANCED adds six key enhancements: extended brightness support (at up to 10,000 nits), Intelligent Motion Smoothing, local tone mapping, genre-based optimization, advanced color control, and adaptive cloud gaming with ambient light adjustments.

No. Neither HDR10+ nor HDR10+ ADVANCED is limited to 4,000 nits, 5,000 nits, or any figure below 10,000 nits. Both specifications support the complete PQ (Perceptual Quantizer) brightness range from 0 to 10,000 nits, as defined by SMPTE ST 2084 — the international standard for HDR video. The 4,000-nit figure that appears in some HDR comparisons originated during a period when a widely used HDR reference monitor capable of approximately 4,000 nits of peak brightness was the standard mastering tool at many studios. Content from that era was graded to a 4,000-nit ceiling because that was what the equipment could display — not because any HDR10+ specification required it. That monitor has since been discontinued.

HDR10+ and all major HDR formats that use the PQ transfer function share the same 10,000-nit brightness ceiling — it is a property of the shared standard, not of any individual format. When a comparison claims one HDR format supports 10,000 nits and another supports only 4,000, it is describing a historical difference in mastering practice, not a difference in what the specifications permit. HDR10+ content has already been mastered to the full 10,000-nit range. The Spears & Munsil Ultra HD HDR Benchmark (2023 Edition) — a professional 4K Blu-ray test disc used by display manufacturers, calibrators, and AV reviewers worldwide — encodes content mastered at 10,000 nits in HDR10+ alongside HDR10 and other formats. It is commercially available and has been reviewed by Sound & Vision, AVForums, and TechRadar, among others.

Most professional HDR content today is mastered to 1,000 nits, matching the peak capability of current premium consumer displays. The brightness a viewer experiences is determined by their display’s panel capability — not the HDR format. A television with 1,000 nits of peak brightness shows all HDR formats at the same maximum brightness. What HDR10+’s dynamic metadata does is ensure your display uses its full brightness capability intelligently: optimizing tone mapping for each scene rather than applying a single fixed setting to the entire program, so every scene looks its best on whatever display you have.

No. Both HDR10+ and HDR10+ ADVANCED support quantization up to 16 bits at the specification level — this has been true since HDR10+’s introduction. Today’s streaming services deliver all HDR content at 10 bits because that is the current ceiling of practical streaming video codecs, a constraint that applies equally to every HDR format. The standard is not the limit; the codec is.

Some HDR formats are marketed as supporting 12 bits. In streaming, these formats are also delivered at 10 bits, the same as HDR10+. The 12-bit capability refers to a specific disc format with very limited real-world adoption by studios. A separate claim holds that a different color encoding method makes 10-bit “equivalent to 12-bit.” Published research puts the actual efficiency improvement from this method at approximately 10% for certain content — a real but modest advantage, and far short of the four-fold precision difference that distinguishes 10-bit from 12-bit.

Bit depth and peak brightness are also independent. HDR10+ uses the PQ (Perceptual Quantizer) transfer function defined in SMPTE ST 2084, which covers content from 0 to 10,000 nits regardless of bit depth. Claims that 10-bit color depth limits HDR to 1,000 nits are technically incorrect.

While standard HDR10+ uses dynamic metadata for scene-by-scene brightness and contrast adjustments, HDR10+ ADVANCED adds new metadata tools for local tone mapping, intelligent motion smoothing, genre-based optimization, and extended brightness control, offering finer-grained adjustments.
