How “FACESWAP” was made

One prompt in. A finished 60-second vertical horror episode out — script, characters, voices, subtitles and cut, all generated. Here is every step, with the real artifacts.

1

The prompt

The only human input. One paragraph describing the story, the hook, and the tone:

A psychological horror short drama. Emma, a college student pulling an all-nighter alone in her dorm, downloads a mysterious face-swap app called FaceSwap. HOOK in the first 3 seconds: she smiles at her phone camera — and her on-screen face smiles back a half-second LATE. ACT 1: the app scans her face and matches her with a stranger — a cold-eyed man. A countdown appears: 72:00:00. She laughs it off, until every screen and mirror around her starts showing the stranger's face instead of hers. ACT 2: her best friend video-calls, then screams and hangs up; a chilling notification arrives: FOUND YOU. Emma tries to delete the app but the countdown jumps to 07:00:00. FINALE: slow knocking at her dorm door. She looks into the mirror — the reflection is no longer her face. She whispers. The reflection answers.

Story blueprint

Before a single shot is written, the AI drafts the story structure for review — logline, beats, where the hook and twist land:

HOOK
The half-second-late smile
3 seconds in: her screen self answers her smile late. The viewer is already unsettled.
ACT 1
The match & the countdown
The app scans her face and pairs her with a stranger. A 72-hour countdown starts.
TURN
Mirrors stop telling the truth
Every screen and mirror begins showing the stranger's face instead of hers.
ACT 2
FOUND YOU
Her best friend screams on a video call and hangs up. Deleting the app only accelerates the countdown.
FINALE
The knock
A knock at the door. The reflection whispers back. Episode 1 ends.

Characters cast & designed

The AI extracts characters from the story, writes each one a bible, and generates a consistent look that follows them through every shot:

Emma HartleyPROTAGONIST
Introverted, soft, warm. The prey — the eyes we see the horror through. Alone in the dorm at 2:47 AM.
Marcus VossTHE MATCH
Cold, calm, precise. The predator living inside her screens.
Maya TorresBEST FRIEND
Outgoing, warm, confident. The scream on the video call.
FaceSwap AppVOICE
Cold spoken notifications — the instrument, and the cage door.

Script, storyboard & shot prompts

A screenwriter agent turns the beats into an 8–15 line English script; a director agent breaks it into shots with camera and lighting direction; every shot gets an explicit image prompt with the characters' reference looks attached — so Emma looks like Emma in every frame.

Voices, subtitles & final cut

Character-matched AI voices perform the lines, subtitles are burned in, and the shots are assembled into a 9:16 vertical episode — then the timeline editor lets you trim, reorder and export.

Your story. Same pipeline.
