16-Panel Storyboard Prompt Create a 16-panel storyboard for a horizontal 16:9 photorealistic Korean subway action thriller sequence. Overall style: Ultra-realistic action movie, Seoul subway concourse, handheld camera, fluorescent lights, teal signage, metal shutters, wet reflective floor, fast but readable editing, strong motion blur, non-graphic close-quarters action. Main character: YUNA, young Korean woman, short messy black bob, oversized charcoal T-shirt, pale denim shorts, black high-top sneakers, small hoop earrings. Keep her identity, hairstyle, outfit, and body proportions consistent. Panel 1: Extreme close-up of YUNA’s shocked face. Her hand reaches toward the camera, blurred in the foreground. Panel 2: Medium side shot. YUNA leans against a closed metal shutter, breathing fast. A smiling male pursuer stands too close on the left edge. Panel 3: Wide subway corridor shot. Two more pursuers appear in the background under fluorescent lights. Panel 4: YUNA lowers her gaze, tense and trapped, then prepares to move. Panel 5: She suddenly ducks past the closest man and breaks into a run. Panel 6: Side tracking shot. YUNA sprints along the metal shutters, strong motion blur trailing behind her. Panel 7: Low angle on her sneakers splashing lightly across the reflective floor. Panel 8: A pursuer grabs toward her shoulder. She twists away at the last second. Panel 9: Close handheld shot. YUNA blocks an incoming arm with both forearms, face focused. Panel 10: She pivots around the attacker, using his momentum to shove him into the shutter. Panel 11: Side medium shot. Another pursuer steps in. YUNA raises her guard, knees bent. Panel 12: Low-angle action shot. YUNA lands a fast front kick to push him back, non-graphic impact. Panel 13: She turns and runs again down the corridor, teal subway signage streaking behind her. Panel 14: Handheld chase shot from behind. The pursuers are farther back, partially blurred. Panel 15: YUNA slides around a corner near glass doors, nearly losing balance but recovering. Panel 16: Final close-up. She stops under a flickering fluorescent light, breathing hard, eyes fierce, ready to keep running. Storyboard layout: 4x4 grid, numbered panels 1 to 16, cinematic action frames, no captions except panel numbers. Image-to-Video Prompt Generate a 28-second horizontal 16:9 ultra-realistic Korean subway action thriller video from the provided first frame. CORE CONCEPT: A tense, grounded action sequence inside a late-night Seoul subway shopping corridor. YUNA, an ordinary young Korean woman, starts cornered beside a closed metal shutter while three anonymous men block her way. She studies the gap, ducks past the closest man, runs through the corridor, gets chased, briefly fights back with practical defensive moves, then escapes around a corner. The tone should feel like a realistic Korean action thriller: fast, sharp, physical, handheld, but not overly stylized. COLOR AND LIGHTING: Use a realistic modern subway corridor color palette. Neutral white fluorescent ceiling lights. Silver-grey metal shutters. Light grey walls. Clean reflections on the polished floor. Natural skin tones at all times. Slight coolness only in the shadows. Avoid strong teal, green, blue, purple, or cyberpunk color grading. Avoid heavy contrast and crushed blacks. The image should feel clear, realistic, and commercial Korean action drama quality. MAIN CHARACTER LOCK: Only one main heroine: YUNA. YUNA is a young adult Korean woman with a short messy black bob haircut, soft bangs, expressive dark eyes, natural skin texture, oversized charcoal T-shirt, pale washed denim shorts, black high-top sneakers, small hoop earrings, and a thin black bracelet. Keep her face, hairstyle, outfit, body proportions, and identity consistent throughout the entire video. Do not duplicate her. Do not change her outfit, hairstyle, or face. SUPPORTING CHARACTERS: Use exactly three anonymous male pursuers. They wear dark casual streetwear or track jackets. They remain secondary threats. Do not add extra pursuers. Do not turn them into main characters. Do not let them replace or duplicate YUNA. SETTING: Late-night Seoul underground subway shopping corridor. Closed silver metal shop shutters, white fluorescent ceiling lights, simple Korean subway signage, reflective polished floor, glass platform doors, pillars, empty storefronts, distant corridor depth. The location stays consistent throughout the whole video. No outdoor scene, no train interior, no rooftop, no explosion. CAMERA STYLE: Photorealistic Korean action thriller cinematography. Handheld camera at close physical distance. Quick but readable cuts. Realistic motion blur during running. Occasional autofocus shift. Natural fluorescent lighting. Clean floor reflections. Use medium-wide establishing tension, side tracking sprint shots, low-angle footwork shots, close combat framing, and final breathless close-up. No drone, no slow motion, no superhero camera, no impossible camera teleporting. TIMELINE: 0.0s - 3.0s: Start exactly from the first frame. YUNA is pressed near the closed silver metal shutter on the right side of the corridor. One pursuer blocks the left foreground, and two others approach from the mid-background. YUNA breathes quickly, eyes moving between the closest man and the narrow gap beside him. Her fear slowly changes into determination. The camera holds a tense handheld medium-wide shot. Lighting stays neutral white and realistic. 3.0s - 5.5s: The closest pursuer takes one step toward her. YUNA lowers her center of gravity, shifts her weight onto her back foot, then suddenly slips sideways along the shutter. She ducks under his reaching arm and squeezes through the narrow gap. The movement is continuous and physically clear: bend knees, lean shoulder, step through, push off. 5.5s - 8.5s: YUNA breaks into a sprint down the corridor. The camera whips slightly and follows from behind and beside her. Her sneakers hit the polished floor with clear contact. Her T-shirt and bob haircut move naturally. The three pursuers react late and start chasing behind her. Motion blur appears in the background, but her body remains readable. 8.5s - 11.5s: Side tracking shot along the closed metal shutters. YUNA runs left to right under white fluorescent lights. The floor reflections stretch naturally under her feet. She glances back once, then accelerates. Keep the color clean and neutral, with natural skin tone. 11.5s - 14.5s: A pursuer catches up and reaches for her shoulder. YUNA plants her right foot, twists her torso, and pulls her shoulder away before he can grip her. She blocks his arm with both forearms. The camera moves close but keeps the action clear. No weapons, no blood, no graphic violence. 14.5s - 17.5s: Using his forward momentum, YUNA pivots around him and shoves him into the closed metal shutter. The impact is quick and non-graphic. The shutter rattles. YUNA immediately steps backward, keeps her hands up, and scans for the next attacker. Lighting remains realistic, not stylized. 17.5s - 20.5s: The second pursuer steps in from the corridor center. YUNA shifts her weight, raises one knee, and delivers a grounded front kick to push him backward. The kick is fast but realistic, with clear balance and foot contact. He stumbles backward without exaggerated flying. 20.5s - 23.5s: YUNA turns and runs again. The camera follows close behind her shoulder. White ceiling lights streak slightly from motion. The pursuers fall farther behind, partially obscured by motion and distance. She keeps one hand near the wall for balance while running. 23.5s - 26.0s: She reaches a corner near glass platform doors. Her foot slips slightly on the shiny floor, but she catches herself by touching the wall with one hand. The camera briefly loses focus, then recovers as she turns the corner. The movement feels urgent and imperfect, not overly choreographed. 26.0s - 28.0s: Final close-up after the corner. YUNA stops under a clean white fluorescent light, breathing hard. Her skin tone remains natural. She looks back toward the corridor, listening to approaching footsteps. Her expression is frightened but determined. She turns her eyes forward again, ready to keep running. End on her intense breathless face. ACTION CONTINUITY: The story must flow clearly: cornered beside shutter → reads the gap → ducks past closest pursuer → sprints → pursuer reaches → block and pivot → shove into shutter → front kick second pursuer → run again → slip at corner → recover → breathless final close-up. Do not begin with her already sprinting. Do not teleport her from one part of the corridor to another. Do not change the corridor layout between shots. PHYSICAL REALISM: Realistic human biomechanics. Clear weight transfer, grounded feet, natural sprinting, believable blocking, pivoting, pushing, kicking, slipping, and recovery. No superhuman jumps. No wire-fu. No impossible body bends. No excessive foot sliding. Combat should feel close, fast, gritty, practical, and non-graphic. AUDIO FEEL: Subway corridor ambience, fluorescent hum, fast breathing, sneakers squeaking on polished floor, footsteps approaching, clothing movement, metal shutter rattle, distant train rumble, muffled voices, tense action sound design. No music required. No subtitles. FINAL STYLE: Ultra-realistic Korean underground action thriller. Natural subway lighting, clean grey-and-white environment, tense handheld camera, practical close-quarters fight, grounded physical action, readable motion blur, urgent cinematic energy. NEGATIVE PROMPT: No heavy teal grading, no green color cast, no blue skin, no purple neon, no cyberpunk lighting, no crushed blacks, no oversaturated colors, no outdoor street, no daylight, no train interior, no rooftop, no explosion, no fantasy powers, no superhero action, no weapons, no gore, no blood, no duplicate YUNA, no extra heroine, no extra pursuers, no identity drift, no changing hairstyle, no changing outfit, no distorted face, no warped hands, no extra fingers, no broken limbs, no floating body, no teleportation, no disappearing characters, no unreadable action blur, no subtitles, no watermark, no black borders.
