Summary
Motion graphics that look like a week of After Effects work are circulating on X, and many of them are made by Claude Code writing JavaScript. This tutorial from Zinho Automates shows how it is done live, with no AI video generator and no cost beyond a Claude subscription.
The walkthrough starts with setup: installing Node.js and FFmpeg, creating an empty project folder, and running Claude Code on Opus 5.5 with effort set to high. It then moves through four levels. The first is the viral one-line prompt, which produces a polished but generic result. The second is a detailed creative brief for a fictional sleep app called Lumen, which gives Claude a director-style role, a strict style guide that bans default gradients and generic fade-ins, and a storyboard approval step before any code is written. The third has Claude pull frames from a real movie trailer with FFmpeg to borrow its pacing, then build an original sci-fi trailer called The Last Pixel. The fourth composes an original music track in code and builds a beat-reactive visualizer.
The main takeaway is that the quality gap comes from the brief, not the model. The video also sets expectations: Claude produces shapes, text, icons, UI, light and particles, not realistic footage of people or places.
