Formalism approach to Substance, Methods&Objectives of Montage

There are two different approaches to Montage among Formalists, First one explains montage as resolving of the material into its elements and subsequent building from them of a film whole (Constructive Editing). In the second approach, Montage is a Dialectic process to make meaning from a conflict. In this article, we want to compare these approaches and look for differences and similarities to unify two opposite approaches. First of all, we need to know how they approach Material of Montage (or Movie), Form and finally to Process itself. So we have few questions: How different is Material of Montage in each approach? Which Concepts are similar between two approaches? How can we unify those approaches? How different approaches to montage itself makes differences in methods of montage?
To find answers we will study Eisenstein's Film Form and Film Sense also Pudovkin's Film Technique and Film Acting and some of their classic movies. At the end of this article, we hope to achieve a united formal approach to Montage of movies.
