Le prompt
[GOAL]
Security-camera footage, 12 seconds, at night: a fixed CCTV camera mounted high on a lamp post watches Maud cross the harbour pier with a flashlight; something large moves in the water beside her.
[REFERENCE BINDING]
Maud corresponds to @Image 1: use it for her face, short dark hair, long dark green oilskin coat, cream sweater, navy trousers and black rubber boots. The views on the sheet show one single woman. Do not reproduce the sheet layout or its gray background.
The location corresponds to @Image 2: the same concrete pier, bollards, iron railing and white-and-red lighthouse, now at night in light rain. Use it only for the location.
[SHOT 1 | 0-3s | Empty pier]
Initial state: the empty pier seen from high above at the landward end, light rain, the lighthouse beam sweeping slowly across the frame. Nothing moves except rain and the beam.
[SHOT 2 | 3-6s | She enters]
Primary event: Maud enters from the bottom left corner, small in frame, holding a flashlight, and walks along the pier toward the lighthouse. End state: she is halfway along the pier.
[SHOT 3 | 6-9s | In the water]
Primary event: beside the pier, a large dark shape breaks the surface for a moment and disappears, leaving a wide ripple. Maud stops and swings her flashlight onto the water. End state: the flashlight beam on the black water.
[SHOT 4 | 9-12s | She looks up]
Primary event: the beam finds nothing. Maud stays still for a beat, then slowly turns and looks straight up at the camera. End state: hold on her small upturned face in the flashlight spill.
[VISUAL STYLE]
Real CCTV footage: fixed high-angle wide view, low-light sensor, heavy digital noise, low bitrate compression blocks, slight frame-rate stutter, washed-out greenish-grey night image, the flashlight and lighthouse beam blooming and clipping. Documentary realism, nothing cinematic.
[CAMERA AND PERFORMANCE]
The camera is locked and never moves, zooms or reframes. Maud moves like a real person at night: careful steps on wet concrete, a short hesitation before turning to the water.
[AUDIO]
<Rain on metal, distant waves, the low electrical hum of the camera, a single splash.>
{No dialogue.} No music.
[No subtitles.]
[EXCLUSIONS]
No on-screen text, no timestamp, no REC icon, no logos. No other people. No monster shown clearly: the shape stays dark and unreadable. No cinematic lighting, no camera movement.
[MAINTAIN CONSISTENCY]
One woman, Maud, matching @Image 1; the same pier and lighthouse as @Image 2; one fixed camera position for all 12 seconds.
Vous obtiendrez
Un plan fixe de 12 secondes, vu d'en haut : la nuit, une forme dans l'eau, un regard vers la caméra.
À surveiller
Tout y est (plan fixe, forme dans l'eau, lampe), mais l'image reste trop belle pour une vraie caméra de surveillance, et la fin part dans un voile blanc. Coût : 3 crédits par seconde en 480p, 147 crédits pour les quatre plans (49 s). Chaque plan peut passer en 1080p sans être regénéré.
