STEP 1
最後まで音が続く素材
動作を最後のコマまで止めずに続ける
AI への指示L-cut source 1: a static close-up of the hands and a hand-crank coffee mill; the grinding sound must run steadily to the last frame. L-cut source 2: a static close-up of a paper dripper on a glass server; quiet so the previous sound can trail in.
L-cut source 1: a static close-up of the hands and a hand-crank coffee mill; the grinding sound must run steadily to the last frame. Character: the man from the character reference sheet: same face, small scar at the end of the left eyebrow, short slightly messy black hair, open plain dark-navy cotton overshirt jacket with one left chest pocket over a plain white crew-neck T-shirt, charcoal grey chinos, black plain sneakers. Location: a small old Japanese kissaten coffee shop with a dark wooden counter, worn leather stools and a window with lace curtains. 0.0s-1.0s: he steadies the wooden coffee mill on the counter with his left hand. 1.0s-3.0s: his right hand starts turning the crank in slow even circles; beans crackle inside. 3.0s-5.0s: the crank keeps turning at the same speed without stopping, a little ground coffee dust on the counter. Shot on a cinema camera with a 85mm lens, one window on the left as the only light source, real skin texture with pores, visible fabric fibers, dark wood mill, brass crank, roasted bean texture. Natural, neutral color, no heavy grading. No text, no logos. Ambient sound: continuous coffee grinding, crisp and close.

Character: the man from the character reference sheet: same face, small scar at the end of the left eyebrow, short slightly messy black hair, open plain dark-navy cotton overshirt jacket with one left chest pocket over a plain white crew-neck T-shirt, charcoal grey chinos, black plain sneakers. Location: a small old Japanese kissaten coffee shop with a dark wooden counter, worn leather stools and a window with lace curtains. 0.0s-1.5s: he holds a gooseneck kettle above the dripper. 1.5s-4.0s: a thin stream of hot water circles over the coffee grounds; they bloom and bubble. 4.0s-5.0s: he lifts the kettle away; steam drifts. Shot on a cinema camera with a 85mm lens, one window on the left as the only light source, real skin texture with pores, visible fabric fibers, paper filter fibers, blooming coffee grounds, glass server. Natural, neutral color, no heavy grading. No text, no logos. Ambient sound: soft pouring water, quiet room tone.
