Study of Shot Length and Moiton as Contributing Factors to Movie Tempo

摘要

This work seeks to lay the framework of film grammer over the video to be analyzed. We use the shot attributes of motion and shot length to produce a novel continuous measure of one of the asesthetic elemnts of films, namely the movie tempo. We refer to our previous work detailing the study of this construct an dits automatic derivation, and also demonstrating its usefulness as an iexpressive elent and as asound basis for higher semantic descriptions such as dramatic events and story elements. Initial assessment of tempo was performed in our study on the basis that the relative improtance of both shot lenglth and motion in formulating the tempo function was the same. In this paper, we analyze their relative contributins to tempo, and demonstrate how these two factors can be manipulated to influence audience perception of movie time.
