Claude + Playwright + AWS Polly → narrated MP4
Same Acme contact flow as the first demo, but the output is a single narrated video instead of an interactive page. Per-step CSS spotlights highlight whatever the narrator is talking about; AWS Polly (Arthur, en-GB, neural) reads each step; ffmpeg
composites the title + caption bars in post and stitches the clips.
How it is made
- Capture. Playwright drives the app, applies spotlight CSS and screenshots clean 1920×1080 frames.
- Narrate. AWS Polly synthesises one MP3 per step using the Arthur (en-GB) neural voice.
- Overlay. A headless Playwright pass renders the title and caption bar PNGs from a tiny HTML template.
- Stitch. ffmpeg composites each still, both overlays and the matching MP3, then concatenates the clips.
