The original title is "How I Made a Product Demo with Claude Code, Playwright, and FFmpeg"

Short summary

The author used Claude Code with Playwright and FFmpeg to generate a 56-second product demo for their open-source Agent OS project in about 30 minutes. Claude Code inspected the app, identified narrative beats, and used Playwright to navigate real product states, recording short clips per beat. A Python script then used FFmpeg to trim, label, and concatenate clips into a final MP4.

• •Claude Code + Playwright + FFmpeg workflow produced a 56-second demo in ~30 minutes
• •Each narrative beat recorded as a separate clip with its own BrowserContext for stability
• •Demo treated as an automated software artifact — regeneratable when the interface changes
