Defining workflow
So this is just a bit of musing.
I need a more comprehensive and fluent workflow to do the compositing. A proven and methodical approach. I need to be able to break apart the roto into hair and other, then feather unique areas, apply an s_edge_blur (is that the best?) and s_refine_matte. Complicated shots where characters are moving toward the camera might need a special treatment.
I’ll continue with what I am currently doing, pass over the entire 1st act, simplify and keep it saveable, and make sure it renders. How many elements might be an issue.
