HDR10 / Dolby Vision
Also known as: HDR, Dolby Vision IQ, HDR10+, HLG, PQ transfer function
HDR (High Dynamic Range) video formats allow displays to show much brighter highlights and deeper blacks simultaneously, producing images closer to what the human eye sees in real life.
HDR10 is the open, royalty-free baseline standard; Dolby Vision is Dolby's premium version with per-scene or per-frame metadata for better accuracy on supported displays.
HDR10 / Dolby Vision, explained at three levels
At home
HDR video looks more vivid and realistic: sunsets are actually bright, shadows have detail, and the overall image looks less 'washed out' than older video. HDR10 and Dolby Vision are two versions of this technology; Dolby Vision is generally considered higher quality but requires Dolby licensing.
At work
HDR10 and Dolby Vision are formats that tell a screen how bright and how colourful each part of a video should be, using a much wider range than older standard video. HDR10 is free and works almost everywhere; Dolby Vision is licensed and adjusts the picture scene by scene. A business buying displays needs to match the format its content was made in, or the picture falls back to a duller version.
At home
HDR10: open standard, static metadata (one set of brightness instructions for the entire video), max 10,000 nits peak brightness spec, 10-bit colour. Dolby Vision: proprietary, dynamic metadata (adjusts per scene or frame), max 12-bit colour depth, 10,000-nit spec. Dynamic metadata allows Dolby Vision to optimize for each scene's specific content and the capabilities of the playback display.
At work
Streaming platforms encode HDR in multiple formats: Netflix encodes Dolby Vision and HDR10; Apple TV+ delivers Dolby Vision; Amazon Prime Video offers HDR10+. Devices receive the format they support: an Apple TV receives Dolby Vision; a budget TV might receive only HDR10. Content mastered for Dolby Vision typically has a Dolby Vision layer and an HDR10 fallback layer in the same file.
At home
HDR uses the PQ (Perceptual Quantizer) or HLG (Hybrid Log-Gamma) transfer functions to encode brightness. PQ (SMPTE ST 2084) maps absolute brightness values to 0-10,000 nits, used for HDR10 and Dolby Vision. HLG is backward compatible with SDR displays and used in broadcast. Wide Colour Gamut (WCG), such as BT.2020 or P3, accompanies HDR for richer colours.
At work
Tone mapping is applied when HDR content plays on displays that can't achieve the mastered brightness. Dynamic metadata in Dolby Vision allows device-specific tone mapping curves. HDR metadata (MaxCLL, the maximum content light level, and MaxFALL, the maximum frame average light level) in HDR10 helps displays make static tone mapping decisions. Professional mastering monitors (e.g., Sony BVM-HX310) reach 1000+ nits with factory-calibrated HDR accuracy.
Real-world examples
At home
Marcus bought an OLED TV that supports both Dolby Vision and HDR10. When watching Netflix, his TV displays 'Dolby Vision' in the corner because Netflix detects his TV's capability and sends the Dolby Vision stream automatically.
At work
Lena's video production company delivers final masters in Dolby Vision for streaming clients. They use a reference monitor calibrated to P3 D65 and a Dolby Vision analysis tool to verify metadata accuracy before submission.
How it compares
| feature | HDR10 | Dolby Vision | HDR10+ |
|---|---|---|---|
| Metadata type | Static (whole video) | Dynamic (per scene/frame) | Dynamic (per scene) |
| Colour depth | 10-bit | 12-bit | 10-bit |
| Licensing | Free/open | Paid (Dolby) | Free/open |
| Major supporters | Universal | Apple, Netflix, LG | Samsung, Amazon |
For analysts
HDR format support is relevant in media, entertainment, and digital signage procurement decisions, specifying the right HDR format for display and playback equipment affects content quality and compatibility.
History & origin
HDR for video content was standardized as HDR10 in 2015 and adopted by UHD Blu-ray and streaming platforms. Dolby Vision, announced a year earlier in 2014, became the premium competitor with dynamic metadata (adjusting parameters per scene). HDR10+ (Samsung's answer to Dolby Vision, also using dynamic metadata but royalty-free) emerged in 2017. Today many TVs support two or all three (Samsung, for example, skips Dolby Vision), and streaming services deliver different HDR formats to different devices based on capability.
