Narrated product walkthroughs — a video pipeline

A storyboard written from each app's own source drives headless Chrome through the real product with a visible cursor and highlight rings; Gemini TTS voices every line, ffmpeg assembles the scenes with captions, and a transcription pass checks that what was said matches what was shown.

Highlights

  1. Demo environments reset and seeded through the public APIs so every take starts clean; off-camera helpers play the second user and claim the guest links.
  2. Hindi and Urdu scripts checked by a Unicode-aware transcription compare with loan-word alias tables; right-to-left captions for Urdu.
  3. Eleven videos produced and eight published on the products' how-to-use pages with WebVTT captions, posters and VideoObject structured data.
