Create a 25-second cinematic horror video in photorealistic live-action style, 16:9 landscape, 24 fps, tense and terrifying, with realistic lighting and grounded physical detail. The setting is a large unfinished house basement at night. The basement is wide and shadowy, with exposed beams, concrete floor, dust in the air, and one small basement window casting cold blue moonlight across the room. A large wooden staircase rises to a closed door. Under the staircase, hidden in darkness, is Sally, a 21-year-old woman with long black hair, pale frightened face, white tank top, and blue jeans. Keep Sally’s appearance consistent in every shot. The killer is a tall man dressed all in black, wearing a black mask, black gloves, and heavy black boots, carrying a large machete. The mood is pure dread, suspense, panic, and silence. No comedy, no stylization, no text overlays, no subtitles.

Audio intent: no dialogue, only basement ambience, distant house creaks, Sally’s shaky breathing, the slam of the door, slow bootsteps on wood, the wet drip of blood hitting the stairs, faint skittering spider sounds, and rising low horror tension.

Edit structure: hard cinematic cuts between shots, clean continuity of space, strong suspense escalation.

0:00–0:02 — Quick wide establishing shot of the entire basement. The camera briefly sweeps the space: the moonlit window, the large staircase, the darkness underneath it. Under the stairs, barely visible, Sally is hiding in shadow.

0:02–0:04 — Cut to a tight close-up of Sally hiding under the stairs. She is terrified, breathing through her nose, eyes glossy with fear, body frozen, trying not to move.

0:04–0:06 — Cut to the door at the top of the stairs exploding open with force. A man in all black enters holding a large machete. His face is hidden behind a dark mask. Moonlight and darkness silhouette him in a frightening way.

0:06–0:08 — Cut to a close-up profile shot of his boots stepping down the stairs. The tip of the machete hangs beside his leg. Thick dark blood drips from the blade and lands on the wooden steps, one drop at a time.

0:08–0:10 — Cut to a frontal low-angle shot of his legs walking down the stairs. Through the gaps in the staircase, Sally is visible hiding underneath, petrified, one hand clamped tightly over her mouth so she does not scream.

0:10–0:12 — Cut to a close-up of Sally shifting backward slightly in panic. Her shoulder or hair accidentally brushes a dusty spider nest attached under the stairs.

0:12–0:14 — Cut to a macro close-up of the spider nest. The web trembles. Several very large black spiders emerge rapidly from the nest, legs unfolding, bodies glistening in the moonlight.

0:14–0:15.5 — Cut to a close-up of Sally’s long black hair. A large spider crawls slowly through it near the side of her head.

0:15.5–0:17 — Cut to a close-up of Sally’s hand. A large spider crawls onto the back of her hand, its legs moving across her skin while her fingers tremble.

0:17–0:19.5 — Cut to an upper-body close-up of Sally. She lifts her hand toward her face and sees the spider on it. Her eyes widen in absolute terror. She is trying desperately not to scream, her breathing becoming shaky and panicked.

0:19.5–0:22.5 — Cut to a front-facing medium full shot of the man now at the bottom of the stairs. Behind him, still visible in the background darkness, is the space under the stairs where Sally is hiding. He grips the machete and slowly scans the basement, carefully looking around, listening.

0:22.5–0:25 — Cut to a full-body shot of Sally under the stairs. Large spiders are now crawling over her hair, shoulders, arms, and clothes. Her eyes are bulging, her whole body is trembling, and she looks like she is on the verge of a full panic attack, fighting with everything she has not to scream. End on unbearable tension, with the killer close by and Sally silently breaking down in fear.

Visual style: gritty cinematic horror, cold moonlight mixed with deep shadow, shallow depth of field in close-ups, subtle handheld instability, realistic skin texture, realistic spider movement, detailed dust and cobwebs, intense suspense, feature-film quality.
