Docs

https://openimageio.readthedocs.io/en/latest/oiiotool.html and specifically ociodisplay https://openimageio.readthedocs.io/en/latest/oiiotool.html#cmdoption-ociodisplay

Usage

With aces $OCIO set

--ociodisplay  %s %s   Apply the named OCIO display and view (optional
                       args: from=, looks=, key=, value=)

Convert linear (acescg) exr to sRGB jpg with Rec.2020 'look' applied.

So this example

• from=acescg (optional inputcolorspace arg)
• display=ACES
• view=Rec.2020

OpenImageIO-1.5.0-OCIO/bin/oiiotool.exe /d/ocio_balls/balls.exr --ociodisplay:from=acescg ACES Rec.2020 -o /d/ocio_balls/out.jpg

In theory, but I cant get it to work... Same setup works in nuke

Convert sRGB jpg 'texture' to a linear exr to display correctly when viewed at Rec.2020

OpenImageIO-1.5.0-OCIO/bin/oiiotool.exe /d/ocio_balls/balls.exr --ociodisplay:from=out_rec2020 ACES Raw -o /d/ocio_balls/out.jpg
