What it does
Lemo-Opuscar is a plugin for Claude Code (Anthropic's coding assistant) that makes short films without a video AI model. You pick one of 59 styles, such as watercolor, ukiyo-e or 1920s newsreel, describe your story, and the assistant writes code that draws each frame, builds the music, adds a text-to-speech voice and mixes the video. You can also create and keep your own style. It is tuned for Claude Opus 5.5. You need Claude Code, Node 20+, Python 3.11+ and ffmpeg, and the README says each film takes 30 to 60 minutes and a fair amount of tokens.
How easy it is to install
D · terminal, several tools or a specific graphics card · Windows
You install the plugin with two terminal commands, but you also need Claude Code, Node 20+, Python 3.11+ and ffmpeg, and the agent installs further packages and sample libraries itself.
Coming soon: install in 1 click with the RepoPicks app.

What Radar could not check
- Whether it works on Windows: the setup and download helpers are shell scripts (setup.sh, fetch.sh).
- Real token cost and time for one film.
- Exactly what the agent downloads and installs on first use and on later self-updates.
- Disk use after voice models (Kokoro, Whisper) and music sample libraries are downloaded.
- How good the films look with models other than Claude Opus 5.5.
- Whether the Chinese voice option (edge-tts, online) sends your script text to Microsoft's service.
