Cinemetrics lab is the latest addition to our site, and is still work in progress. When finished, the lab is envisaged to offer students of film history a range of analytical tools that will help them dissect, visualize and compare film-related data. We started with a large-scale comparative chart which looks a little like a star map. It is a scattergraph each dot on which represents a film available on our database. Select areas by dragging a rectangle to zoom in and see better different areas of film history. Once you have found your film on this map you will see how it relates to thousands of other films on the x-axis of time (past 111 years of film history) and on the y-axis of average shot lengths. What we intend to do is to add more tools to the lab in order to augment its statistics apparatus and enhance its means of data visualizations.

Year/ASL chart. Note the Log10 scale on the y-axis. It allows us to see all films in the very widely spread high ASL range.

List of films in this lab:

Rear Window: (7) ASL 8.4
Rear Window: (7) ASL 8.8


We see two measurements of the same film, Hitchcock's Rear Window, done from the same DVD in the same screening room situation, this one Rear Window: (6) ASL 8.8 done by Jordan Beck, a student in my Montage class, and this one  Rear Window: (6) ASL 8.4. Jourdan used the tool in the advanced mode, me in the simple one.

A Note: Ideally, the results should have been identical, but they are not. First, there were different choices each of us took, for instance, I opted for including the shot under the opening credits (76.4 seconds); apparently, Jordan did not; also, I did more occasional double-clicks (at least 3). Though the graphs look similar, the numbers don't quite tally. This is partly due to the fact that both measurements were done during a public projection, not the best environment for concentration, and also without have seen the film for a long time (this, at least is true for me). To have a more reliable count one of us (or both) should remeasure the film at home.
