Reuse components using Sequences

Let's say we want to show two titles that both fade in after each other.

In order to make a title reusable, we first factor it out into it's own component.

tsx
import {interpolate, useCurrentFrame} from 'remotion'
 
const Title: React.FC<{title: string}> = ({title}) => {
    const frame = useCurrentFrame()
    const opacity = interpolate(frame, [0, 20], [0, 1], {extrapolateRight: 'clamp'})
 
    return (
      <div style={{opacity}}>{title}</div>
    )
}
 
export const MyVideo = () => {
  return (
    <div
      style={{
        flex: 1,
        textAlign: "center",
        fontSize: "7em",
      }}
    >
      <Title title="Hello World" />
    </div>
  );
};

tsx
import {interpolate, useCurrentFrame} from 'remotion'
 
const Title: React.FC<{title: string}> = ({title}) => {
    const frame = useCurrentFrame()
    const opacity = interpolate(frame, [0, 20], [0, 1], {extrapolateRight: 'clamp'})
 
    return (
      <div style={{opacity}}>{title}</div>
    )
}
 
export const MyVideo = () => {
  return (
    <div
      style={{
        flex: 1,
        textAlign: "center",
        fontSize: "7em",
      }}
    >
      <Title title="Hello World" />
    </div>
  );
};

Now we can use the <Sequence> component to limit the duration of the first title and time-shift the appearance of the second title.

tsx
import { Sequence } from "remotion";
 
export const MyVideo = () => {
  return (
    <div
      style={{
        flex: 1,
        textAlign: "center",
        fontSize: "7em",
        backgroundColor: "white",
      }}
    >
      <Sequence from={0} durationInFrames={40}>
        <Title title="Hello" />
      </Sequence>
      <Sequence from={40}>
        <Title title="World" />
      </Sequence>
    </div>
  );
};

tsx
import { Sequence } from "remotion";
 
export const MyVideo = () => {
  return (
    <div
      style={{
        flex: 1,
        textAlign: "center",
        fontSize: "7em",
        backgroundColor: "white",
      }}
    >
      <Sequence from={0} durationInFrames={40}>
        <Title title="Hello" />
      </Sequence>
      <Sequence from={40}>
        <Title title="World" />
      </Sequence>
    </div>
  );
};

You should see two titles appearing after each other. Titles which are not shown during a frame are unmounted. This is why the layout did not shift (as it does in HTML) when you added a second title. If you want the titles to overlap in time, use absolute positioning if necessary.
