That's the method I use 95% of the time. We have a simple gizmo based on it. The trick is to get a crop of the reference frame of a representative area set to reformat, blur, reformat back up, divide, then multiply source.
Then if the flicker's not global mask the result off. Great for match flicker too, just reverse the divide's inputs.
