You would have to be more specific INRM, I work in TV and (some) Film production, and just estimating time is an entire industry in itself. When a script comes into a studio it MUST be in a certain format to even be read by a studio aid. This format usually equates to one minute per page. If it's not in that format it will immediately be thrown away.
Then studios count the number of each kind of shot, interior, exterior, effects, etc etc. This is how they determine time and budget.
Typically a non- effects laden motion picture for domestic theatrical release has a three month shooting schedule and then a six month post and marketing cycle. However, there may be literally years between the shooting and marketing / release period. This is all based on focus groups and market surveys to try and release a film at its most strategic time.
As far as the shooting and editing, the honest truth is, this time line has far less to do with the technology involved, and much more to do with the schedules of the stars and producing / directing talent involved.
Here's an example....
The first Star Wars movies staring in 1977 were released in three year intervals using all practical effects and some potical compositing. The new movies are shot completely digitally, and principal photography takes about three months. But the post is so long and involved they are still taking three year intervals.
If you could tell me what you want to know, such as filmed television program, sitcom three camera television program, animated program, animated feature, film feature, summer blockbuster, documentary, etc, I could provide some real life averages.
