I'm writing another episode, and I understand, as a rule of thumb, that one page of dialogue equals one minute of film. Can someone tell me if that's true, especially for a web series? Thanks.
What sort of script is it that you're working on?
It is quite accurate over a standard 90 to 120 page script. It is not
page by page accurate. Five pages of dialogue delivered quickly in
the 1930's comedy style will not be five minutes of screen time.
The line "the epic battle ensues" will not last three seconds on
screen.
One great way to "get a handle" is to set a timer and read your
pages out loud. That will give you a reasonable approximation of
how long the scene will be.
How long your film/webseries can be is limited by your provider/host.
What's a 1930's comedy as opposed to "Three's Company"?
