Runway Ruby adds ACES color and EXR sequence export

Runway's Ruby, a model for converting standard-range video into high-dynamic-range output, added exports suited to professional color workflows: scene-referred ACEScg image sequences in half-float EXR format. The announcement specifies support for ACES 1.3 and 2.0. Export announcement and Ruby product description.

Scene-referred images represent scene light before the final adjustment for a particular display. That gives effects artists a common basis for combining imagery and applying the final look later. Ruby's export change therefore concerns how its output enters compositing and finishing work. OpenEXR's explanation.
