Gamut Compression Implementation

Document Workspace

Matthias Scharfenberg & Carol Payne - Working Group Co-Chairs
Alex Forsythe - ACES Technical Lead
Steve Tobenkin - ACES Adoption/Comms Lead
 

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
