Vis Exo EFFECT — HORROR

Horror Video Effects, Free

Make an ordinary room frightening. The light fails the way real ones do — a dying bulb, a stuttering tube, a failing supply, a storm — something stands in the dark whenever it goes out, blood hits the lens, and the sounds and title cards to go with it. Built over your own footage, in the browser.

Why Make Horror Here

Light that fails properly

More than ten light styles: a dying bulb with dropouts in bursts, a fluorescent tube that buzzes and stutters, a failing mains supply that sags and restrikes, a storm, a poltergeist strobe, a candle, a flickering subway car, police lights. The flicker has the lag and warm-up of a real filament, so it reads as light and not as a filter.

Something in the dark

Whenever the lights drop out a figure can be there: a person standing, a tall thin thing, a child, someone peeking round the frame, a crouching shape, a far-off figure, or just eyes. It glimpses somewhere new each time, lurks in one place, creeps closer, stalks the tracked subject, turns round, or jumps the moment the light returns.

It stands behind your subject

With a tracked subject selected, the figure stands behind them, cut by their outline, and stalks them through the shot.

Blood on the lens

Splatter, drips, arterial spray, a smear or creeping edges, in fresh, bright, dark, stage or black ichor, kept to the whole frame or to the subject or the room around them.

Palettes and scenes

Tungsten, sickly green, moonlight, sodium, blood red or the colours of the lamps already in your shot, and ready-made scenes to start from.

Sound and titles

Matching horror sound effects and voices, and title cards built for it: possessed lettering, a tape-counter card and slow, dreadful lines.

Frequently Asked Questions

How do I make a horror video effect for free?

Open the tool: Horror Flicker is already on. Load a dark-ish room, pick a light style and palette, turn on the figure if you want one, and export. No watermark, no sign-up.

Does it add a monster to my footage?

It can add a dark figure that appears in the moments the light goes out. It is a drawn silhouette, not a rendered creature, and it is built to be seen for a flicker and not stared at.

Can I keep the effect to one person or to the room?

Yes. Set Keep the look to the person, a tracked subject or a rotoscope shape, or to everything but them.

Will it work on a phone?

The effects run in the browser on a phone; heavier AI features such as the tracked subject prefer a computer.

Is anything uploaded?

No. The footage stays on your device.
