Opus 5.5 + Motion Canvas: AI explainer video studio
Opus 5.5 writes the script and scene code, Motion Canvas animates, Manim draws diagrams and Kokoro voices it, with voiceover length driving scene timing.
Opus 5.5 + Motion Canvas just f*cking killed the explainer video agency.. add Manim + Kokoro and you've got the building blocks for your own explainer studio the stack: Opus 5.5 → write the script, split it into beats, write the scene code http://anthropic.com/claude-opus-5-5 Motion Canvas → animate in TypeScript with a live preview editor, built for visuals synced to a voiceover http://github.com/motion-canvas/motion-canvas Manim → graphs, equations and diagrams that draw themselves. community fork of the engine 3Blue1Brown built http://github.com/ManimCommunity/manim Kokoro → 82M open-weight voice model, Apache 2.0, runs on your own machine http://github.com/hexgrad/kokoro the useful part: the voice drives the timeline every line of the script becomes one voice clip. the clip length sets the scene length. rewrite one line, regenerate that clip, and only that scene re-times the loop: script → beats → voice → scenes → diagrams → sync → preview → export give the agent your topic, your audience, one reference video and the format (16:9 or 9:16). lock the first 5 seconds, then let it carry the style through the rest save this, then go build your own explainer studio, run by your AI employee ↓
