# Demo Video Generator ## Overview Generate 1920x1080 demo videos with voiceover, transitions, and CSS animations from a single prompt. Orchestrates Playwright (HTML-to-frame rendering), FFmpeg (compositing and transitions), and Edge TTS (neural voiceover) MCP servers. ## Prerequisites - Python 3.11+ and `uv` package manager - FFmpeg installed (`ffmpeg -version`) - Playwright chromium browser (`uv run playwright install chromium`) - Internet connection for Edge TTS voice synthesis ## Instructions Install the framecraft plugin from the marketplace: ```bash claude plugin marketplace add jeremylongshore/claude-code-plugins-plus-skills claude plugin install framecraft@claude-code-plugins-plus ``` ### Quick Start ```bash uv run python framecraft.py init my-demo # scaffold a project uv run python framecraft.py render scenes.json --auto-duration uv run python framecraft.py validate output.mp4 # quality check ``` ### MCP Orchestration When Playwright, FFmpeg, and Edge TTS MCP servers are available, framecraft orchestrates them directly for maximum control over each frame and audio segment. ### Pipeline Fallback When MCP servers are not available, framecraft runs an atomic CLI pipeline that handles everything in one call. ### Workflow 1. **Story design** -- Choose a narrative arc (problem-solution, hero journey, before-after) 2. **Scene authoring** -- Write HTML scenes with CSS animations, or use built-in templates 3. **Rendering** -- Playwright captures frames,...
