An apparatus and method for home and professional media editing aims is presented. The method uses task -oriented approach rather than well-known "timeline" or "storyboard" ways for dealing with media (video and audio) resources. The aim of this paper is to describe AVSEL, a language that can be used for formalization of user actions during editing video resources. In particular, logic aspects of editing process is underlined, namely, editing process is considered as process of making decisions and AVSEL is descriptor language to express editing logic in formal terms. Syntax and language semantics are given along with explaining samples. Some advantages of this approach, such as rendering optimization, flexible control of editing process are described.
