How this pair works
Your Trelby file is parsed into a canonical screenplay model (by verified content, not just the file extension), then rendered as Open Screenplay Format. Open Screenplay Format background: The Open Screenplay Format was published in the early 2010s by Kent Tessman (Fade In’s author) as an open XML schema so tools could interoperate without licensing. Fade In saves it natively inside .fadein archives, and Scrite exports it.
