resolve-dctl

Color Transform Lanaguage library providing transforms for Davinci Resolve

Includes:

S-Curves - Generate S-Curve using various Sigmoid functions
Mid-Highlight - Green Highlight on Middle Gray at 18% reflectance (40.5 IRE) or selectable IRE at Data Levels
Mid-Select - Show Mid Gray at 18% reflectance (40.5 IRE) or select IRE at Data Levels; everything else Black
Blackout - Black Out specified area based on luma
Whiteout - White Out specified area based on luma
full2legal - Convert Data signal to Video levels using proper quantization equation
legal2full - Convert Video signal to Data levels using proper reverse quantization equation
Channel-Saturation - Adjust Red, Green and Blue saturation based on Upper and Lower thresholds
Gray-Chart - Generate Chart with Black, Middle Gray and White in Scene or Linear gamma
Signal-Limiter - Limit clip based on Signal levels
Luma-Limiter - Limit clip based on overall Luma levels
Gray-Chart-Extended - Generate Gray Chart + custom defined Peak value (i.e. 1000 NIT); Uses Linear gamma
Clamp - Clamp values between 0.0 and 1.09
Clamp-Extended - Clamp values between 0 and 1000
Step-Ramp - Generate linear ramp with up to 4096 steps and custom scale
Inverse-S-Curves - Generate Inverted S-Curves using various Sigmoid functions
Power-Knee - Highlight roll-off based on Power function
Inverse-Power-Knee - Inverse Highlight roll-off based on Power function
Quantization - Quantize clip from 1 - 32 bits using Data Level or Video Level
Blanking - Blank to Black or Alpha. Custom Aspect Ratios from 1:4 to 4:1

Transforms use Rec.709 Color Primaries where applicable. Most DCTL files can be used with either a Scene or Linear timeline gamma.

Installation

Save the DCTL files to the relevant locations based on the host Operating System as noted below:

C:\ProgramData\Blackmagic Design\DaVinci Resolve\Support\LUT\

/Library/Application Support/Blackmagic Design/DaVinci Resolve/LUT

LUT folder located within DaVinci Resolve App
