Quick development update:
I made a few additional changes to the gamut-compress master branch.

  • On the Nuke node and the Nuke Blinkscript Node:

    • Add helper functions for calculating max distance limits given a source gamut or an input image.
    • Set default distance limit values according to average of popular digital cinema cameras
    • As suggested a couple meetings ago, I modified the threshold parameter to be adjustable for each RGB component.

  • On the Resolve DCTL I’ve fixed a bug with the shadow rolloff parameter not working.

  • Thanks to some excellent help from @Jacob I’ve added a Fuse version of the GamutCompress tool for Blackmagic Fusion. It works in Fusion Studio and in Resolve Lite or Resolve Studio’s Fusion page. No watermark, fully functional.

  • For the record, both the Nuke node and the Fuse are fully functional in Nuke Non-Commercial, and Blackmagic Resolve Lite.
