Fountain format

Fountain is a plain text format for screenwriting. Example:

FADE IN:

INT. COFFEE SHOP - DAY

JOHN (30s, tired programmer) stares at his laptop.

JOHN
This code does not work.

SARAH slides into the seat across from him.

SARAH
Have you tried turning it off and on again?

FADE OUT.

The server understands all standard Fountain elements. Scene headings, character cues, dialogue, parentheticals, transitions, action lines, section headings, and notes.

Runtime estimate

The server estimates runtime based on the standard rule of 1 page equals 1 minute of screen time. Page count is calculated from action and dialogue lines.
