Over time, distribution of shot lengths in movies has moved closer to pink noise

by Bayle
2 Mar 2010 at 1:12 am

The statistics of shot durations in 150 films from 1935 to 2005 were analyzed. From about 1970 to the present, the power spectrum of shot durations in individual films has tended to become more like pink noise (power ~= 1/f). Also, autocorrelation shows that the lengths of nearby shots has become more and more correlated.

The authors, Cutting, DeLong, and Nothelfer, speculate that the pink noise

Bayesian truth serum

Neville told me about this neat article from ‘04. It presents a way to offer rewards to people taking a poll in such a way so as to motivate them to be honest, with no prior information about what the distribution of correct answers is. Apparently, previous such techniques are based on the idea of rewarding people for agreeing with other people’s answers. This new thing about this tech
