Vincent Wei released 15 ten-second motion-design films that Claude Opus 5.5 wrote from one prompt each

A small team that wanted a ten-second animated film used to need a motion designer, a brief, and about a week. Vincent Wei published mg-styles-15 on 2 October, a repository of fifteen ten-second motion-design films that Claude Opus 5.5 wrote from a single prompt each, with the films, the prompts and the full source code in the repository under MIT. The repository had 240 stars at the time of writing.

The fifteen styles are: frame-by-frame line boil, isometric 2.5D, flat vector, line art, 3D render, shape morph, sticker explainer, cyberpunk HUD, collage cut-out, aurora glassmorphism, geometric Bauhaus, 80s synthwave, pixel art, liquid motion, and variety captions. The last one renders at 9:16 vertical for social video; the other fourteen are horizontal.

What is in the repository

The README says each film started from one prompt sent to Claude Opus 5.5 and then went through two rounds of review and revision through what the author calls an AI jury system. The initial generation is a single prompt. The repository holds the final films under videos/, the complete prompts under prompts/, the generated code for each film under demos/, and shared assets including textures, HDRI files and font references.

The rendering is browser-native where possible. The README says each film is drawn with SVG, Canvas, WebGL or Three.js, with Blender used for the 3D-render style. A live showcase runs at vincentwei1021.github.io/mg-styles-15.

The licence and what the prompts contain

The MIT licence covers the author's work. Third-party assets keep their original licences, including CC0 for public-domain images, OFL for the fonts and BSD-3-Clause for a sound library. The prompts folder lists each style as a plain-text brief: the look, the brand constraints, the output format and the length. A reader can change the brief, change the length or switch an output to vertical and re-run.

The author also published two earlier repositories, anything2explainer and video-talkcraft, both for making explainer videos with Claude Code and Codex. mg-styles-15 is the first to publish the prompts as the artefact alongside the films.

For a product or marketing team, the prompt is the part that is hard to write and the part the author has done the work on. Copying a prompt from the repository is faster than writing one from scratch, and reading the generated code afterwards shows what a working Three.js motion-design file looks like for a given style. The repository does not say how long each film took the model to produce, so the cost of running these at volume still needs measuring on your own account.
