Introduction
Core is a TypeScript library for programmatic video editing using WebCodecs. It runs entirely in the browser and supports headless editing, making it ideal for automating video processing tasks.
For server-side usage, you can integrate Core with Playwright or Puppeteer. While using a browser for video rendering in a server environment may seem unconventional, Chromium is one of the most sophisticated rendering engines available, making it a powerful choice for this purpose.
Installation
npm install @diffusionstudio/coreUsage
The engine is commonly used in the following way:
import * as core from '@diffusionstudio/core';
const composition = new core.Composition();Version History
