A Proposal of Shot Size Index for Cinemetrics In Teams of Osamu Tezuka’s Storyboard Analysis

Abstract

Cinemetrics, the quantitative study of video works, focuses on the average duration per shot. However, other indices are needed for the development of this field. In this paper, we propose and validate an index based on the shot size in terms of direction. Given its importance in the extant video research, we first summarize the existing studies on shot size. We then apply the proposed index to the works of Osamu Tezuka, targeting storyboards that are published as books because identification of authors and selection of indices is easy. Tezuka had a unique disposition toward shot size, which emerged from the necessity to cut costs when he started TV animation. We verified the index by comparing it with the storyboards of Hayao Miyazaki, who has a contrasting background. Statistical validation revealed that the shot size between Tezuka and Miyazaki differed significantly, indicating that shot size is a useful index.
