This document is intended to help studio and post production partners better understand the considerations when creating a content creation and delivery specification for Dolby Vision HDR masters and the associated deliverables. This is merely a reference and studios are welcome to customize the specifications that we’ve outlined to suit their specific needs.

You may omit formats as per your own requirements.

If you are at a studio and looking to define your spec, this is a great starting point to help outline the specific details that will help your post partners deliver a complete and correct project.

Dolby Vision Metadata

Metadata Version	4.0.2 for CMv4.0 (preferred)
	5.1.0 for CMv4.0 (preferred with cinema targets)
	2.0.5 for CMv2.9 (legacy - no longer recommended)
Level 254 CM Version	4 1 (indicates latest automatic backwards compatible algorithm) or 4 2 (indicates user-modified backwards compatible metadata)
Canvas Area	1:1.77778
Active Image Area	Project or shot dependent (should match letterboxed / pillarboxed area)
Frame Rate	Must match corresponding video content
Mastering Display Primaries	P3D65 or BT.2020 (P3D65 recommended)
Color Encoding Primaries	P3D65 or BT.2020 (must match corresponding video content)
Trim Metadata	Included as L8 (optional, follow Dolby Vision Best Practices Guide)
MaxFALL/MaxCLL	Included as L6 (optional)

 

 

Note:

• • All Dolby Vision Metadata must be validated using Metafier that is part of the Dolby Vision Professional Tools.
    • All FAIL or ERROR messages must be resolved.
    • All WARNING messages should be reviewed and adjusted as necessary.

• • SDR Rec.709 deliverables as well as all encoded bitstreams are derived from the Dolby Vision HDR master/mezzanine and its metadata. Thus, you should run a full, linear review pass by validating theHDR content and Dolby Vision metadata through a Dolby Vision content mapping process to SDR Rec.709, 100nit.
  • Textless elements must be delivered with the same Dolby Vision metadata from the original texted shots. It is assumed that the all substituted text elements for localized versions are the same approximate size and luminance. This will ensure  consistent Dolby Vision mapping across all localized versions.
  • ISXD track file is not yet widely supported.
  • Optional: HDR10 static metadata values, MaxCLL and MaxFALL should be calculated on the ST.2084(PQ) master and included as Level 6 metadata in the Dolby Vision metadata. Only active program material should be included when calculating these values, and all slates, head leaders, tail leaders, etc. must be excluded.
