# Opus Js Animations

Direct and render films made entirely in JavaScript, from an idea to a frame-exact MP4, working like a film director.

Direct and render films made entirely in JavaScript, from an idea to a frame-exact MP4, working like a film director. Take the brief, then ask where the sound comes from (the person's audio file, a YouTube or other link fetched with yt-dlp, a score generated in JavaScript, or a voiceover from their ElevenLabs or OpenAI key). Study that audio, ask about look, pacing, 2D or 3D (three.js or not) and the points to land, and present a director's treatment scene by scene.
