opus-video-skills

The skill in this repository teaches Claude Opus 5.5 to produce a complete hand-painted video, covering storyboarding, animation, review, lyric synchronization and final encoding. All imagery is generated procedurally in code; no image or video generation model is involved. Every frame is a pure function of time, rendered in headless Chrome and encoded with ffmpeg.

Draws every shot with p5.js and the p5.brush watercolour library. Characters act through a library of expressions and motion principles. Music videos are cut to the measured beat, and lyric videos carry word-by-word karaoke subtitles. Example: a 31-second lyric video for 陶喆《小镇姑娘》. Documentation.

• Claude Code with Claude Opus 5.5
• Node.js, Google Chrome, ffmpeg
• Python 3 with numpy (painted-animation tempo detection only)

As plugins (recommended). In Claude Code:

/plugin marketplace add tuzhechen2005/opus-video-skills
/plugin install painted-animation@opus-video-skills

/plugin update fetches new versions.

As personal skills. Clone the repository once and link the skills you want:

git clone https://github.com/tuzhechen2005/opus-video-skills ~/opus-video-skills
ln -s ~/opus-video-skills/skills/painted-animation ~/.claude/skills/painted-animation

Updating is then a git pull in ~/opus-video-skills.

Upgrading from painted-animation. This repository was previously the single painted-animation skill, cloned directly into ~/.claude/skills/painted-animation. That layout no longer works, because the skill now lives in skills/painted-animation/. Remove the old clone and install with either method above.

Describe the video in Claude Code. The matching skill is selected automatically, or it can be invoked by name:

Make a 15-second video of Clawd trying to catch a butterfly.

For a music video, provide the song audio and an LRC lyric file, then optionally answer one combined question about the desired story and feeling, recurring imagery and anything to avoid. The question is never split into five fields and may be left blank. The skill scaffolds a project, presents a storyboard, and reviews every shot. It never starts the complete final render without asking for an explicit local-or-cloud choice; choosing local prohibits cloud full rendering and returns exact local commands.

A new style is a new directory under skills/ containing a SKILL.md, a runnable template/ and at least one worked example, plus an entry in .claude-plugin/marketplace.json. The existing skill's contract is that frames are pure functions of time, render.mjs produces contact sheets and parallel frame renders, and every shot is reviewed from rendered images before the final encode.
