The following are our preferred project settings for delivering HLG HDR to YouTube.
1. Display HDR Video (P3-ST2084)2. Preferences. Decode Options. Decode H.264/H.265 using hardware acceleration.3. Preferences. Use 10-bit precision in viewers if available. Use Mac display color profiles for viewers.4. Color Management settings. Color science may be DaVinci YRGB (for a node-based workflow), DaVinci YRGB Color Managed or DaVinci Resolve Color Managed with Automatic Color Management. Timeline color space here is DaVinci WG/Intermediate because we’re working with Cullen Kelly’s LUTs, but it could be the native log color space of the camera (e.g. S-Log3/S-Gamut3.cine, etc.) as well. The output color space should be Rec.2020 ST2084 1000 nits.5. DaVinci YRGB Color Managed with automatic color management will work, too.6. Be sure to enable Dolby Vision. Mastering display settings: 1000-nit, BT2020, D65, ST2084, Full7. Export Settings. Format: QuickTime. Codec: H.265. Check ‘use hardware acceleration if available.’ Quality: we prefer 80,000 Kb/s. Encoding Profile: Main 10.8. Export settings. Data Levels: Auto. Dolby Vision Profile 8.4.9. The video will be recognized as HLG in apps that don’t support Dolby Vision, such as Instagram and YouTube, as well as on non-Dolby Vision playback devices like the Samsung S90C QD-OLED pictured here.
