clip-js

clip-js is a browser-based video editor built with modern web technologies such as Next.js and Remotion, designed to provide real-time editing and rendering directly in the browser. It enables users to create and edit video compositions using a timeline interface, combining video, audio, images, and text layers into a single project. The system uses a WebAssembly port of FFmpeg to perform high-quality rendering, allowing export of videos without relying on server-side processing. It includes interactive controls for trimming, splitting, and arranging media elements with precise timing. The editor supports dynamic adjustments such as opacity, positioning, and layering to fine-tune compositions. It also incorporates keyboard shortcuts and responsive UI elements to improve workflow efficiency. Overall, it demonstrates how full-featured video editing can be achieved entirely within a web application.
