Is it possible to animate Post Process Volume effect changes in a matinee?

On a Post Process Volume, I am using a grainy film effect on a scene using a sepia color film tint and lowered saturation using, and during the matinee, I’d like for it to slowly come to color through animating the sepia to go back to white and raise the saturation.

Is this possible?
Thanks!

You can’t access PP parameters from Matinee as far as i know. What you can do is make two post process volumes that cover your animated area(one with sepia another with saturated color grading), call these PP volumes into the level BP and then animate Blend Weight parameters of the volumes with a Timeline. You can also animate color grading parameters and use a single pp volume but just interpolating between two different PP volumes’ blend weights would be easier i think.
