ACES in After Effects — Razor Crest VFX Lecture 05

As we continue the Razor Crest lectures, we need to be able to view ACEScg in After Effects. Since there is currently no way to do this natively, we'll use the OpenColorIO plugin by fnord. This will allow us to view a one-to-one representation of the image between the V-Ray frame buffer and After Effects. I'll also show you the method to maintain After Effects' Display Color Management as disabling it is a more cumbersome approach than simply using the Color Profile Converter. Disabling AE's Display Color Management requires multiple steps, and you have to Preserve RGB for each image and sequence, and remember to do it on output too depending on your workflow. The Color Profile Converter is one step once and it works for all your footage, which is more convenient in my opinion. I should have added more explanation in the video. More explanation of why we have to do this: You have enable "Linear working color space" for After Effects to work with linear color, otherwise it won't display properly regardless of ACEScg or sRGB. And by enabling it, if Color Management is turned on, which is on by default, it automatically gamma corrects linear color based on your working space. That's what you want for linear sRGB. Secondly, ACEScg is a linear colorspace, but AE doesn't know of it, and assumes that an exr, for example, is linear sRGB. However, the color primaries between ACEScg and sRGB are different. That's why we have to use the plugin to convert ACEScg to sRGB, or else the colors will be wrong. But the plugin also applies gamma correction, so now you get two applications of gamma correction and the image now looks washed out. If you have disabled Color Management, then this is not a problem, otherwise, we have to fix the double correction. That's why we use the Color Profile Converter. I highly recommend not disabling AE's color management because it causes other less obvious problems when outputting from AE. Keep in mind that this entire workflow might be outdated for you. AE 2023.1 has built-in OCIO, which might simplify things for you These lectures were originally built for a college VFX class that I teach, taking students from beginner to intermediate level. Over the course of this 9-hour course, brush up on PBR surfacing with UDIMs, learn about lighting, AOVs, render layers, batch and sequence rendering, EXR compositing, and ACEScg with Maya, V-Ray, and After Effects.
