The prompt

Scene paragraph A packed boxing arena on fight night, photoreal sports drama. Bright white lights over the ring, a roaring crowd in the dark stands, haze in the air. A young Latina female boxer with tight braids wears a red satin robe over red trunks and red gloves. Live-action footage shot on 35mm film, real people, natural skin and textures.

Medium shot inside the ring under the lights, her robe off, facing an opponent in blue, the camera on a tripod outside the ropes. 0–2s: she bounces on her feet and throws a jab at full speed. 2–4s: she launches a big right hook, and at the moment it lands time slows to extreme slow motion. 4–6s: in slow motion, sweat drops spray off the opponent's headgear while her face stays fierce. 6–8s: time snaps back to full speed as the opponent stumbles back and she resets her stance. Throughout: one clear slowdown and speed-up while the camera holds steady, one continuous take.
