<Composition>

This is the component to use to register a video to make it renderable and make it show up in the sidebar of the Remotion development interface.

A composition represents the video you want to create, as a collection of clips (for example, several <Sequence>) that will play back to back to form your video.

src/Root.tsx
tsx
import { Composition } from "remotion";
 
export const RemotionRoot: React.FC = () => {
  return (
    <>
      <Composition
        component={Component}
        durationInFrames={300}
        width={1080}
        height={1080}
        fps={30}
        id="test-render"
        defaultProps={{}}
      />
      {/* Additional compositions can be rendered */}
    </>
  );
};
src/Root.tsx
tsx
import { Composition } from "remotion";
 
export const RemotionRoot: React.FC = () => {
  return (
    <>
      <Composition
        component={Component}
        durationInFrames={300}
        width={1080}
        height={1080}
        fps={30}
        id="test-render"
        defaultProps={{}}
      />
      {/* Additional compositions can be rendered */}
    </>
  );
};

API​

A <Composition /> should be placed within a fragment of the root component (which is registered using registerRoot()).

The component takes the following props:

id​

ID of the composition, as shown in the sidebar and also a unique identifier of the composition that you need to specify if you want to render it. The ID can only contain letters, numbers and -.

fps​

At how many frames the composition should be rendered.

durationInFrames​

How many frames the composition should be long.

height​

Height of the composition in pixels.

width​

Width of the composition in pixels.

component or lazyComponent​

Pass the component in directly or pass a function that returns a dynamic import. Passing neither or both of the props is an error.

note

If you use lazyComponent, Remotion will use React Suspense to load the component. Components will be compiled by Webpack as they are needed, which will reduce startup time of Remotion. If you use lazyComponent, you need to use a default export for your component. This is a restriction of React Suspense.

defaultProps​

optional

Give your component default props that will be shown in the preview. You can override these props during render using a CLI flag.

note

Type your components using the React.FC<{}> type and the defaultProps prop will be typesafe.

note

Passing huge objects to defaultProps can be slow. Learn how to avoid it.

Example using component​

tsx
import { Composition } from "remotion";
import { MyComp } from "./MyComp";
 
export const MyVideo = () => {
  return (
    <>
      <Composition
        id="my-comp"
        component={MyComp}
        width={1080}
        height={1080}
        fps={30}
        durationInFrames={3 * 30}
      />
    </>
  );
};
tsx
import { Composition } from "remotion";
import { MyComp } from "./MyComp";
 
export const MyVideo = () => {
  return (
    <>
      <Composition
        id="my-comp"
        component={MyComp}
        width={1080}
        height={1080}
        fps={30}
        durationInFrames={3 * 30}
      />
    </>
  );
};

Example using lazyComponent​

tsx
export const MyVideo = () => {
  return (
    <>
      <Composition
        id="my-comp"
        lazyComponent={() => import("./LazyComponent")}
        width={1080}
        height={1080}
        fps={30}
        durationInFrames={3 * 30}
      />
    </>
  );
};
tsx
export const MyVideo = () => {
  return (
    <>
      <Composition
        id="my-comp"
        lazyComponent={() => import("./LazyComponent")}
        width={1080}
        height={1080}
        fps={30}
        durationInFrames={3 * 30}
      />
    </>
  );
};

Organize compositions using folders​

You can use the <Folder /> component to organize your compositions in the sidebar.

tsx
import { Composition, Folder } from "remotion";
 
export const Video = () => {
  return (
    <>
      <Folder name="Visuals">
        <Composition
          id="CompInFolder"
          durationInFrames={100}
          fps={30}
          width={1080}
          height={1080}
          component={Component}
        />
      </Folder>
      <Composition
        id="CompOutsideFolder"
        durationInFrames={100}
        fps={30}
        width={1080}
        height={1080}
        component={Component}
      />
    </>
  );
};
tsx
import { Composition, Folder } from "remotion";
 
export const Video = () => {
  return (
    <>
      <Folder name="Visuals">
        <Composition
          id="CompInFolder"
          durationInFrames={100}
          fps={30}
          width={1080}
          height={1080}
          component={Component}
        />
      </Folder>
      <Composition
        id="CompOutsideFolder"
        durationInFrames={100}
        fps={30}
        width={1080}
        height={1080}
        component={Component}
      />
    </>
  );
};
