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 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 durationInFrames={40}>
<Title title="Hello" />
</Sequence>
<Sequence from={40}>
<Title title="World" />
</Sequence>
</div>
);
};

You should see two titles appearing after each other. Sequences which are not shown during a frame are unmounted.
Sequences by default are absolutely positioned - you can use layout="none" to disable that.
