Printer Papers Part 4 | Final Delivery, Post Production, Editing, OCIO and ACEScg
Added 2022-12-13 21:34:58 +0000 UTCIn part 4 of this series, I cover the ACES color profile and how it can be applied using OCIO to ensure that colors remain consistent from the Houdini viewport to your final delivery format. Please check out this guide for more details about ACES and color spaces in general.
I also show different methods for editing, color grading, and manipulating renders.
The first portion of this focuses on DaVinci Resolve, which can be downloaded for free and is available on Windows, OSX, and Linux. This is the most straightforward way to edit, color and deliver a CG project as everything can be done in one app and requires very little technical steps.
I cover Nuke next, which is also available on Windows, OSX, and Linux but can be quite expensive. It's a useful tool to know if you're working as part of a larger team as collaborating and sharing your node graph is much easier.
Lastly, I show how the OCIO command line tools can be used to automate color space transformations and be scripted to be a more automated step within a larger pipeline.
If you're interested in this, check out this guide on setting the OCIO environment variable, download the ACES config.ocio and read more about how Houdini has implemented OCIO
Comments
The earlier parts of this series cover rendering ACES through Karma, this is just how the deal with the color space in Nuke and Resolve. Is there some part of this workflow that doesn't make sense or are you thinking of a different delivery method outside of these compositing softwares?

2023-07-12 18:11:49 +0000 UTCI'd leave the .exr the way it is which should be ACEScg. You shouldn't need to do any transforms in Nuke in this case as it might result in doubling up the color transform. You should be able to turn on OCIO in the Nuke color tab and enable ACEScg there, so you'd be viewing it correctly but not adjusting any of the pixel values or color transform. You can see more info about the color tab here: https://learn.foundry.com/nuke/content/comp_environment/configuring_nuke/using_ocio_config_files.html

2023-02-06 12:30:10 +0000 UTCExporting from Nuke to Davinci should I write the .exr as ACEScg or ACES 2065-1? I want to stay in ACES going from Nuke to Davinci.
