What problem does it solve? Producing a polished product demo video normally requires video editing skills, recording tools, and voiceover work. This Skill turns screenshots or scene descriptions into a complete narrated video by orchestrating browser rendering, text-to-speech, and video compositing. ## Core Features & Use Cases - Story-driven scene design: Provides proven story structures (Classic Demo, Problem-Solution, 15-Second Teaser) with per-scene pacing, color language, and typography rules. - Automated rendering pipeline: Generates HTML scenes, captures them with playwright, synthesizes narration with edge-tts, and composites everything with ffmpeg into a 1920x1080 video. - Graceful fallbacks: When MCP tools are unavailable, it still outputs scene HTML files, narration scripts, a scenes.json manifest, and a build.sh with manual ffmpeg commands. - Use Case: You just shipped a new CLI tool and need a 30-second launch video. Describe the key moments, and the Skill produces styled terminal scenes, narration audio, and a final MP4 with crossfade transitions. ## Quick Start Create a 30-second demo video for my product using the demo-video skill, with a hook, three feature scenes, and an end card with our URL.
