Introduction

Welcome to the hlg-tools wiki! This is where documentation and tutorials are kept for the project. You can also find a collection of pq2hlg commands in the Movies Database.

Tools

These are the main parts of the hlg-tools suite. Most of them generate 3D LUTs that perform some type of conversion.

• pq2hlg - LUT generator for converting PQ (typically HDR10) into HLG
• hlg2pq - LUT generator for converting HLG into PQ (typically HDR10)
• mono709 - LUT generator for grayscaling BT.709 SDR
• pqstat - Accepts a raw 10-bit PQ stream and outputs basic statistics

Movies Database

The Movies Database wiki page contains reasonable pq2hlg commands for movies I have personally converted to HLG.
