HDR & Dolby Vision Masterclass

HDR & Dolby Vision Masterclass

Instructor: Jose Luis Tamez

Jose is a senior content engineer at Dolby Labs and an instructor/consultant for Dolby Vision. He actively does in-person and remote training for companies like Fox, HBO, Cinemax, Disney, Warner Media, Sony, ARRI, Viacom and many others.

Session Overview

The aim of this course is to equip colorists and post professionals with pertinent concepts and methodology to start grading in HDR and work downstream to master and QC deliverables (HDR10, SDR, Cinema48 nit trim, IMF) using the Dolby Vision Workflow.

The course is divided into two sections - the first section covers HDR core concepts - principles, terminology, best practices for image acquisition and setting up the grading workflow.

The second part covers practical applications in DaVinci Resolve. Students will learn how to set up and master a Dolby Vision project from start to end - We will set up the color management, show the workflow and requirements prior to the Dolby analysis, and then work our way down to trims, and generate deliverables in ProRes, IMF and derived versions in SDR. We will also discuss how to export metadata, and QC the deliveries and metadata - an important step prior to studio delivery.

Part 1: Core Concepts

What is HDR?

Understanding HDR Terminology -

SDR/HDR/Color Space

Wide Color Gamuts

Transfer Functions (OETF/EOTF)

Perceptual Quantization (PQ)

Nits/Contrast Ratio

Color Volume/Tone/CIECAM2 Model

HDR Standards - SMPTE ST. 2084, ITU-T BT.2100

Hybrid Log Gamma (HLG)

Maximum Content Light Level Metadata (MaxCLL)

Maximum Frame Average Light Level Metadata (MaxFaLL)

Chroma Subsampling

Characteristics of HDR video - Resolution, bitrate, framerate, wide color gamut and high dynamic range.

Understanding Luminance Levels - Barten Ramp, PQ EOTF Curve, PQ vs HLG.
