Overview
Dolby Vision is a proprietary HDR (High Dynamic Range) format from Dolby Laboratories, introduced in 2014. Unlike pure grip or lighting equipment, it is an end-to-end technical chain for moving images: from color correction (grading) in post-production, through mastering and encoding, to distribution and playback on end devices. The key difference from HDR10 lies in the dynamic metadata: while HDR10 uses static values for the entire film, Dolby Vision transmits scene- or frame-specific instructions on how a display should render brightness, contrast, and colors.
Technical Specifications
- Color Depth: up to 12 bits per channel (HDR10: 10 bits)
- Peak Brightness: mastering specified up to a maximum of 10,000 nits; professional reference monitors currently operate up to approximately 4,000 nits
- Color Space: supports Rec. 2020 (ITU-R BT.2020)
- Dynamic Metadata: according to SMPTE ST 2094-10 (Dolby format), scene- or frame-wise
The metadata exists in different profiles, for example as single-layer (e.g., Profile 5, Profile 8 with backward compatibility to HDR10/SDR) or as dual-layer with an additional enhancement layer (e.g., Profile 7 for Ultra HD Blu-ray).
Use in Post-Production
Dolby Vision is indirectly relevant to the camera and lighting departments because the material shot on set is later graded in an HDR workflow. The actual creation of Dolby Vision metadata occurs during grading: common color suites like DaVinci Resolve, Baselight, or Flame can generate Dolby Vision metadata and set so-called trims, with which colorists manually adjust the rendering for different display brightness levels. For distribution, Dolby collaborates with studios and post-production houses through a certified pipeline process. A further development, Dolby Vision 2, was announced in September 2025.
