starburst()v4.0.468

Part of the @remotion/starburst package.

Renders a WebGL2-based retro starburst ray pattern as an effect for canvas-based components such as <Video>, <HtmlInCanvas> and <Solid>.

Use it when you want to apply starburst rays through an effects array instead of rendering the <Starburst> component.

starburst() replaces the underlying pixels instead of blending over them. It is usually the first effect in a chain, or applied to a <Solid> background before other effects.

Example​

MyComp.tsx
import {starburst} from '@remotion/starburst';
import {AbsoluteFill, Solid} from 'remotion';

export const MyComp: React.FC = () => {
  return (
    <AbsoluteFill>
      <Solid
        width={1280}
        height={720}
        color="black"
        effects={[
          starburst({
            rays: 16,
            colors: ['#ffdd00', '#ff8800', '#ff4400'],
            rotation: 15,
            smoothness: 0.1,
            origin: [0.5, 0.5],
          }),
        ]}
      />
    </AbsoluteFill>
  );
};

API​

Pass an object with the following properties.

rays​

The number of rays in the starburst pattern. Must be between 2 and 100.

colors​

An array of hex color strings for the rays. Colors are assigned to rays cyclically. Must contain at least 2 colors.

rotation?​

Rotates the starburst pattern in degrees. Defaults to 0.

smoothness?​

Controls the softness of the ray edges. 0 gives hard edges, 1 gives very soft edges. Default: 0.

origin?​

UV coordinate of the starburst origin. [0, 0] is the top-left corner, [1, 1] is the bottom-right corner. Default: [0.5, 0.5].

disabled?​

When true, the effect is skipped. Defaults to false.

Requirements​

starburst() uses a WebGL2 backend. During renders, enable WebGL via Config.setChromiumOpenGlRenderer() (for example 'angle'). See Using WebGL during renders.
