Example

tsx
import {AbsoluteFill} from 'remotion';

const Letter: React.FC<{
  children: React.ReactNode;
  color: string;
}> = ({children, color}) => {
  return (
    <AbsoluteFill
      style={{
        backgroundColor: color,
        opacity: 0.9,
        justifyContent: 'center',
        alignItems: 'center',
        fontSize: 200,
        color: 'white',
      }}

      {children}
    </AbsoluteFill>
  );
};
// ---cut---
import {linearTiming, TransitionSeries} from '@remotion/transitions';
import {crossZoom} from '@remotion/transitions/cross-zoom';

const BasicTransition = () => {
  return (
    <TransitionSeries>
      <TransitionSeries.Sequence durationInFrames={40}>
        <Letter color="#0b84f3">A</Letter>
      </TransitionSeries.Sequence>
      <TransitionSeries.Transition
        presentation={crossZoom({strength: 0.4})}
        timing={linearTiming({durationInFrames: 30})}
      />
      <TransitionSeries.Sequence durationInFrames={60}>
        <Letter color="pink">B</Letter>
      </TransitionSeries.Sequence>
