What's the difference between infrared and night vision in this tool?

The Infrared look inverts colours and boosts saturation to mimic a heat-map, where areas appear in vivid contrasting colours. The Night Vision look applies a green tint with raised contrast to imitate a military scope. Infrared is colourful and surreal; night vision is monochrome-green and tactical.

How is the thermal effect created technically?

It combines CSS filters: a hue rotation of around 180 degrees flips colours to their opposites, high saturation intensifies them, and a brightness/contrast adjustment exaggerates the bright-vs-dark separation so the result reads like a heat map. The night-vision look instead uses a strong green tint with high contrast.

What can I use these effects for?

They're popular for stream overlays and intros, horror or sci-fi aesthetics, music videos, reaction content, and previewing a stylised look before committing to it in a full editor. Because the effect is live and reversible, you can toggle it on and off while watching.

Thermal & Night-Vision Video Effects (and How They Really Work)

Q: Does this actually detect heat like a real thermal camera?

No, and this is important: a browser filter only remaps the colours that are already in the video. A real thermal camera senses long-wave infrared radiation that an ordinary camera can't see at all. The filter recreates the look of thermal imaging for creative and aesthetic purposes — it does not measure temperature or reveal anything that wasn't already in the footage.

Thermal & Night-Vision Video Effects

How real thermal and night-vision cameras work, how a browser filter recreates the look, and the creative ways people use it.

Open the Infrared Filter

First, an honest disclaimer. This is a visual effect, not a sensor. It remaps the colours already present in a normal video to look like thermal or night-vision footage. It does not detect heat, reveal hidden objects, or see in the dark. Keep that in mind for anything beyond aesthetics.

How real thermal and night-vision cameras work

Understanding the real devices makes the effect more fun to use. They're actually two completely different technologies:

Thermal (infrared) imaging detects long-wave infrared radiation — heat — that every object emits. It needs no visible light at all, which is why warm bodies glow against a cool background. The familiar rainbow "heat map" is a false-colour palette applied to invisible temperature data.
Night vision works in the opposite way: it amplifies the tiny amount of visible and near-infrared light that is present and intensifies it thousands of times. The classic green image comes from the phosphor screen in the eyepiece — green is the colour the human eye distinguishes best at low brightness.

What the filter actually does

A browser can only work with the pixels in the video it's given, so it imitates these looks with standard CSS adjustments:

Effect	Recipe	Result
Infrared	Hue rotate ~180°, Saturation 200%, Brightness 110%, Contrast 140%	Colours flip to their opposites and intensify into a surreal heat-map look
Night Vision	Strong green tint, Brightness 80%, Contrast 150%	A monochrome-green, high-contrast tactical scope appearance

The infrared trick relies mostly on the 180° hue rotation: it pushes every colour to the opposite side of the colour wheel, so skin tones and warm areas swing toward cool blues and greens while cool areas turn warm — the visual signature of a thermal map. The heavy saturation and contrast then exaggerate the separation.

Creative ways to use it

Stream overlays and intros. Toggle the night-vision look on a webcam or gameplay clip for a tactical, "spec-ops" intro.
Horror and sci-fi aesthetics. The surreal infrared palette instantly makes ordinary footage feel alien or unsettling.
Music and reaction videos. A quick effect change punctuates a beat drop or a reveal without any editing software.
Previewing a stylised grade. See whether a clip suits a heavy, inverted look before you commit to recreating it in a real editor.

Because the effect is applied live and is fully reversible, you can flip between the normal image and the effect while the video plays — handy for comparing or for timing the switch to a moment in the footage.

Frequently asked questions

Does this actually detect heat like a real thermal camera?

No. It only remaps colours already in the video. A real thermal camera senses infrared radiation an ordinary camera can't capture. This recreates the look for creative use — it doesn't measure temperature or reveal anything new.

What's the difference between the Infrared and Night Vision looks?

Infrared inverts colours and boosts saturation for a vivid heat-map; Night Vision applies a green tint with high contrast for a military-scope feel. One is colourful and surreal, the other monochrome-green and tactical.

Will it work on any video?

Yes — paste a URL from any supported platform and apply the effect. It changes only how the video is displayed in your browser; the source file is untouched and other viewers see the original.
