Turns one image into the back of a DVD case: a big hero still on top, a row of smaller stills below, a synopsis block, then credits, a spec bar (runtime, rating, audio) and a barcode along the bottom. Any genre fits: a hockey brothers sports film, a 3 AM convenience-store thriller, a road movie, a documentary about an old bathhouse.

How to prompt: start with dvdbacklayout, DVD back cover, then the genre, then the hero still (who, where, doing what), the small stills (one thing per still; for NSFW keep each small still to one person, because group positions in small cells melt together), synopsis, credits, spec bar and barcode, and finally the color scheme. Write on-image text in English or Chinese only; Japanese comes out garbled. MOSS layout mode (a JSON with a box for each element) also works and gives a steadier layout.
