Chapter 124: Hardware accelerated encoding

Core Idea

Encoding is the process of converting a sequence of images into a video file. Besides rendering frames, encoding is one of the two steps required to create a video.

Key Concepts

• Enable hardware accelerated encoding
• In SSR APIs
• In the CLI
• In the Studio
• With the config file
• In Remotion Lambda and Cloud Run
• Prerequisites for NVENC (Linux/Windows)
• Controlling quality using --video-bitrate

Code Examples

const serveUrl = '/path/to/bundle';
const outputLocation = '/path/to/frames';

const inputProps = {
  titleText: 'Hello World',
};

const composition = await selectComposition({
  serveUrl,
  id: 'my-video',
  inputProps,
});


await renderMedia({
  composition,
  serveUrl,
  codec: 'prores',
  outputLocation,
  inputProps,
  hardwareAcceleration: 'if-possible',
});
