​​Goals

​​The work completed by the Gamut Mapping Architecture group, which resulted in a scene-referred RGB Gamut Compression Algorithm, requires implementation of the algorithm in major software applications.  The scope of work for the working group is as follows:
  • ​​Outline baseline implementation standards and documentation
  • ​​Work with software developers to ensure implementation across specialties such that productions can use the tool at scale 
​​
​​Our initial target software for implementation will be:
​​On Set: Pomfort LiveGrade
​​VFX: OpenColorIO
​​Grading/Finishing: Baselight, Resolve, Colorfront
​​

​​Deliverables

  • ​​Documentation detailing the implementation best practices and test materials (if applicable).
  • ​​Reference implementations in at least one application for major production uses (on set, VFX, grading/finishing)
​​

​​Workflow Stages

​​

​​On Set

  • ​​Should be tracked as an LMT in AMF
  • ​​Should default to always on in on-set applications

​​Dailies

  • ​​If used on set, should also be present in dailies media 

​​VFX

  • ​​Should not be baked into pulls
  • ​​Should be treated in VFX as “pixel healing” in the comp, and should not be inverted out on return to DI

​​Grading/Finishing

  • ​​Need a way to track VFX vs non-VFX shots, as VFX will have the gamut compression already applied
