Modern films are actually cut quite rapidly. I think the ASL for a modern film is like 2 seconds.
Comparing from 50 to even 100 years ago, ASL’s have always been semi-varied. It really depended on the director or genre of film. However, early films were cut quicker (ASL of 4-6 seconds) until the invention of sound where I think it went up to like 11 seconds. When they had to add in all the audio they kind of lengthened the ASL.
But really, I think the significance on the change of ASL is due to both the choice of the director and the technology.
Some directors tend to use longer shot lengths for cinematic or dramatic purposes, eg. action movies are cut quicker than dramas. Even in like 1915 Soviet directors realized that shot length could affect the emotional outcome of a film. The films in the Soviet film era tended to change quickly between slower ASL’s to quicker edits.
So, really, its all about aesthetics, the genre, and the directors vision of the film that really influenced the average shot lengths :)
