Before you begin: to access production-level settings, you must have adequate permission. You need to be either the production admin or account admin. 

To access the screenplay builder settings, go to your Production Settings as shown below. 

With the Screenplay Builder, you create or edit a fiction script. As you shoot and ingest material into Flow, you make rough cuts for each scene and export the screenplay to your edit suite.

If you don't want to use fiction scripts, you can disable this setting as seen below. Also, you can read more about the Screenplay builder in the article Creating or editing a fiction script using the Screenplay app.
