15sSci-Fi Horror Alien Home Invasion Chase Sequence
A 15-second multi-shot sci-fi horror sequence set in a modern house at night, where a giant alien creature crashes through a window and chases a woman through corridors and stairs until a man shoots it dead. The prompt lays out five timed shots with specific action beats, camera movement implied by the chase, and dim warm lighting with silhouettes.

Prompt (original, unmodified)
High-tension sci-fi horror sequence inside a modern house at night. Dim warm lighting, long hallways, polished floors, soft rain outside. Large translucent curtains move gently from the wind. Shot 1 (0–3s): A man and woman stand frozen inside the living room. The man grips a handgun tightly, staring toward a massive window covered by thin translucent curtains. Outside the curtain— a huge distorted silhouette slowly moves. Shot 2 (3–5s): Suddenly the curtain EXPLODES inward. A massive alien creature crashes through the glass. The man fires instinctively but gets knocked backward onto the floor. The woman screams and runs. Shot 3 (5–9s): The creature chases her aggressively through the house. She sprints down a corridor, slips around corners, races down stairs while the creature crawls rapidly along walls and ceiling behind her. Furniture gets smashed as it pursues her. Shot 4 (9–12s): She stumbles into a downstairs room— dead end. She falls backward against the wall. The creature slowly crawls closer toward her across the floor, towering over her. Its face comes inches from hers. She freezes in terror. Shot 5 (12–15s): A loud GUNSHOT. The creature jerks violently and collapses sideways beside her. Smoke drifts in the doorway. The man stands there holding the gun, breathing heavily.

How this prompt compares
The techniques this prompt uses are more common in cinematic realistic prompts than in the library overall:
| Technique | In cinematic realistic | Library average | Lift |
|---|---|---|---|
| handheld | 31% | 24% | 1.3x |
| low-key | 22% | 17% | 1.31x |
Across all 5,926 prompts, the techniques used here appear at: tracking 41%, wide shot 26%, handheld 24%, warm tone 17%.
The 15s duration is not arbitrary: 71% of the prompts in this library that state a duration ask for exactly 15 seconds — Seedance 2.0 accepts clips up to 15 seconds, so 15s is the model's ceiling and the most common choice.
