How this pair works
Your Movie Magic Screenwriter file is parsed into a canonical screenplay model (by verified content, not just the file extension), then rendered as Trelby. Trelby background: Trelby began in 2003 as the commercial Blyte, was open-sourced and renamed in 2012, and remains free software — maintained by its community and notable for still importing formats other apps abandoned, including Adobe Story’s .astx.
