"director of film editing"?
I've read the relevant Wiki entry, yet I'm at a loss. http://en.wikipedia.org/wiki/Film_editor
I need a term to convey the idea that nowadays a film editor's role has grown bigger, a term that would convey the difference between film editors and a person who directs them (just like a director of photography directs cinemathographers who work for him\her).
Actually, I'm trying to translate the Russian term режиссер монтажа (which is fairly new, by the way). The rough translation would be "director of film editing" (If I follow the "director of photography" model).
