Three physical measures of the 160 films are used in the analyses below, and one interaction between them. First, the average shot lengths (ASLs) of each filmwere determined. Segmenting films into shots has been a tedious and ongoing process, starting with the measurements by Cutting et al (2010). Subsequently, each filmhas been gone over several times by several individuals both with computer assistance and by hand. Although we occasionally find additional transitions previously missed, we are confident that we have found greater than 99% of themin each film
