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

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