core vs editly
Browser-based video engines compared
core provides a browser-side engine for composing and rendering media on a timeline, while editly creates finished videos from code using ffmpeg. core is suited to interactive browser applications with a custom editing interface; editly is oriented toward scripted, repeatable video generation.
core: Compose and Render Video in the Browser
Diffusion Studio Core is a TypeScript engine for composing and rendering video, audio, and images in browser-based timeline applications. It suits developers building editors or media tools that need interactive playback and browser-based output.
editly: Create Videos from Code and Media Clips
Editly is a Node.js command-line tool and JavaScript API for assembling videos from clips, images, titles, and audio. It suits creators and developers who want repeatable edits defined in code, with transitions and overlays rendered through ffmpeg.
