What they did
According to the repo README, the video was made in two generations, both in Claude Code: a first pass on Opus 5.5 Medium, kept in a legacy folder, and a second on Opus 5.5 that produced everything else. The only direction given was to use the Clawd character design and to give each lyric interesting visuals and transitions; after the first generation the author also asked for p5.brush strokes and for every scene to flow into the next. Opus wrote a shot-by-shot storyboard, then an animation guide it used to brief sub-agents running in parallel, one per chapter. Every frame is painted with p5.js in headless Chrome and the render script encodes the MP4 with ffmpeg. The author says no scene ideas came from him.
How it went
The finished video is on YouTube and the repository, with about 2,100 stars when checked, contains everything needed to re-render it from the nine chapter files. The README gives no token cost, wall-clock time or count of failed attempts. The author has since published a separate, more general base for making Claude animations the same way, which he describes as more reliable, suggesting the first approach needed rework to be reusable.
Worth knowing
The song is not the author's: it comes from a 2024 Udio generation found on YouTube, with lyric interpretations from a third party. Rendering needs Node, Chrome and ffmpeg and paints frame by frame, so budget time for it. This account is a README rather than a write-up: it states what was given and what came out, not what went wrong along the way.
