Generate a video: demo_vid_generate(repo="chitchat") — auto-starts the target webapp, records it, adds voiceover, composes MP4
Draft a script: demo_vid_script_draft(repo="chitchat") — reads the README and generates a narration script
Browse the depot: Categorized gallery of produced videos with inline player, rebuild, delete, and insert into repo README
Chat about it: Built-in chat with personalities, example prompts, and local LLM integration (Ollama/LM Studio)

demo_vid_generate automatically starts the target repo's backend and Vite frontend before recording. Zombie-kills stale processes first. No manual setup — the pipeline scans for start.ps1 and webapp/ directories.
Required: speech-mcp (voiceover), Playwright (recording), FFmpeg (composition). Optional: blender-mcp (3D titles), OBS-mcp (human-in-video), stems-mcp (music), vfx-mcp (effects).
Backend: 11134, Frontend: 11135, speech-mcp: 10909. See WEBAPP_PORTS.md.
