Core Idea

Video encoding involves heavily compressing the video data to reduce the file size, which is a lossy process. This document explains a few factors and settings that can be used to control the quality of the video.

Key Concepts

• CRF
• Resolution (Unsharp text)
• JPEG Quality
• Color accuracy
• GIF Colors
• Video bitrate
• x264 Preset

Code Examples

const MyComponent = () => {
  return <div>Hello World</div>;
};

const Root: React.FC = () => {
  return (
    <Composition
      width={1920}
      height={1080}
      fps={30}
      durationInFrames={100}
      component={MyComponent}
      id="MyComp"
    />
  );
};
