Discuss Kevin’s Test case proposal

Proposal for resolving the conflict between ‘swappable core rendering’ vs ‘doing everything in LMT’

Minimum viable OT update.

Proposal for an alternate/backup plan. The intent here is to make the minimum number of changes to the existing SSTS framework, addressing as many of the issues as possible. This could include, but is not limited to:

This version would accept some issues inherent in the current system, such as hue skews, and mismatches between SDR and HDR.

The point of this track is not to stop work on alternative renderings that may improve things further, but to provide a backstop in case those other avenues fail for some unforeseen reason, and to provide a steelmanned version of the existing method to measure any alternatives against.

And to allow the current system to be “the best it can be”

Christophe Brejon’s Recap

https://chrisbrejon.com/articles/ocio-display-transforms-and-misconceptions/

Status update on OpenDRT being used live on Baldur’s Gate 3 as a replacement for the current SSTS

As a side point to the minimum viable OT update, I would like to add to the agenda a small status update on where our art directors stand are w.r.t. our use of a tweaked version of OpenDRT 0.0.82b1, their experience with it and their evaluation of OpenDRT 0.0.90b2 and JzDT. We will announce the date of the next Panel from Hell where we will announce the official date where this will all go live pretty soon. By this and considering that OpenDRT 0.0.92b2 and JzDT are converging on a similar rendering with minor differences, I hope to enlighten where we might want to go with the improved rendering.
