Remotion Rule: Light Leaks

Light Leaks

This only works from Remotion 4.0.415 and up. Use npx remotion versions to check your Remotion version and npx remotion upgrade to upgrade your Remotion version.

<LightLeak> from @remotion/light-leaks renders a WebGL-based light leak effect. It reveals during the first half of its duration and retracts during the second half.

Typically used inside a <TransitionSeries.Overlay> to play over the cut point between two scenes. See the transitions rule for <TransitionSeries> and overlay usage.

Prerequisites

npx remotion add @remotion/light-leaks

Basic usage with TransitionSeries

import { TransitionSeries } from "@remotion/transitions";
import { LightLeak } from "@remotion/light-leaks";

<TransitionSeries>
  <TransitionSeries.Sequence durationInFrames={60}>
    <SceneA />
  </TransitionSeries.Sequence>
  <TransitionSeries.Overlay durationInFrames={30}>
    <LightLeak />
  </TransitionSeries.Overlay>
  <TransitionSeries.Sequence durationInFrames={60}>
    <SceneB />
  </TransitionSeries.Sequence>
</TransitionSeries>;

Props

• durationInFrames? — defaults to the parent sequence/composition duration. The effect reveals during the first half and retracts during the second half.
• seed? — determines the shape of the light leak pattern. Different seeds produce different patterns. Default: 0.
• hueShift? — rotates the hue in degrees (0–360). Default: 0 (yellow-to-orange). 120 = green, 240 = blue.

Customizing the look

import { LightLeak } from "@remotion/light-leaks";

// Blue-tinted light leak with a different pattern
<LightLeak seed={5} hueShift={240} />;

// Green-tinted light leak
<LightLeak seed={2} hueShift={120} />;

Standalone usage

<LightLeak> can also be used outside of <TransitionSeries>, for example as a decorative overlay in any composition:

import { AbsoluteFill } from "remotion";
import { LightLeak } from "@remotion/light-leaks";

const MyComp: React.FC = () => (
  <AbsoluteFill>
    <MyContent />
    <LightLeak durationInFrames={60} seed={3} />
  </AbsoluteFill>
);
