filmación
/filmaˈθjon/ · B2 · noun · f
filming
🎬🎥 filmación = film + -ación (the act of), so film-ing as an action noun
Spanish takes film and adds -ación, the same ending as English -ation. It turns a verb into the act of doing it. Say film-ma-ción: it is the act of filming. Compare grabación (recording) and publicación (publishing).
