Any news about this one ?
I posted about this some time ago here
https://forum.corona-renderer.com/index.php/topic,11447.0.htmlSince then, I made some tests overlaying 2 video layers, and yes, if you make the second layer opacity like 50%, the quality is improved. It's more difficult if you decide later to add a third and more layers to improve quality.
But I noticed the new Vray has this option as a new feature in their demo video for Maya.
So at least someone else cares about this.
EDIT: ups, seems there was already a topic from 2017 with this. Well feel free to delete this
