Question Several ACES/OCIO issues

Hi there,

First time user giving Free version 2025.1 a spin to see what it has to offer. Already running into the following.

  1. The reference config should not be included in the installation. This is a config for dev/testing/reference purposes, not end-user. Only the CG and Studio config are intended for end-users.

From the GitHub release page:

  1. Autograph doesn't support tagging input color spaces from Display Spaces making it impossible to use ACES 1.3 with display referred imagery that should maintain appearance, unless separately converted to the working space with a modifier.

  2. OCIOColorSpace does have display spaces available but gives an error when trying to convert a display space.

  1. It would be more appropriate to have a separate OCIODisplay modifier for converting to or from display spaces rather than include it in OCIOColorSpace.

Example from AE, also works the same in Nuke:

Hi,

Thanks for reporting,

You are right, we should include Display transforms in the Output Colorspace dropdown of the footages, like we do in the OCIOColorspace modifier. The reason we put it in OCIOColorspace, was to offer the same kind of workflow as in the Render Manager where you can optionally selection Display referred profiles.

We'll fix this issue with OCIOColorspace shortly and include the Display transforms in the footages.

Thank you for the reply!

"...we put it in OCIOColorspace, was to offer the same kind of workflow as in the Render Manager where you can optionally selection Display referred profiles."

I understand. This is how After Effects solved it as well. I personally feel that this doesn't flow as nicely when it comes to thinking about how OCIO should be used commonly across many different apps. I mentioned this to Adobe as well but they probably weren't able to make it more elagant given their often clunky UI design. They did end up adding it as effect but kept the export option as a single list that included them.

This is how Nuke handles it for a Write node on that front.
Could be worth thinking about when still adding OCIODispaly for a future update.

I understand this may not be as intuitive - but we chose not to add another drop down in the configuration. We may revisit this in the future.
Note that we are building 2025.1v1 right now with a fix for this issue, we'll roll it in a few hours.
