Cinemetrics, Exploring Movie Dynamics with Statistical Style Analysis
“In verse studies, scholars count syllables, feet and stresses; in film studies, we time shots.”
I accidentally discovered the databases at Cinemetrics, where you can look up movie statistical information like Average Shot Length (ASL) to see graphic maps of the data in order to visually understand the flow dynamics of any of 3,295 currently listed films.
Many recent films display an ASL of under five seconds per shot: “The Departed” (3.2 seconds), “Dreamgirls” (2.5 seconds), “Casino Royale” (3.4 seconds), “Sweeney Todd” (4 seconds). On the other hand, some films have notably longer ASLs: “The Darjeeling Limited” (8.2 seconds), “There Will Be Blood” (13.5 seconds), “Paranoid Park” (16.5 seconds).
It would be easy to calculate the average shot length of any film by dividing the running time by the total number of shots but, Cinemetrics goes much further… The Cinemetrics Software Tool is a free, downloadable application or online device created by statistician and computer scientist, Gunars Civjans that lets you analyze, record and submit the sequential scene length of any film to the database – including your own. There are two statistics modes available: the simple mode and the advanced mode. Simple mode only records the frequency of shot changes. The advanced mode allows up to eight buttons to be used to record the different types of shots.
From this data you can study the trendlines of any film. If advanced mode was used to record movie data, a table containing statistical data for each shot type will be displayed.
“Taking shot lengths of a running movie is a manual operation performed in real time, and like any such operation – driving a car or playing a video game – it, too, takes a little practice and patience to master,” explains the author of 10 User tips from Yuri Tsivian.
Cinemetrics has a second database that presents the data created by Barry Salt: “The basic idea behind my methods of statistical style analysis is that the form of films noticeably differ from one to another, and that the variables used to study this should be based on the concepts that film-makers actually use.”
Barry Salt tabulates and analyzes change in camera angle and the variations in depth of shot in the data he provides and in his latest work, Moving Into Pictures
