create-vo-anchored-beat-video

Purpose

Produce a shortform explainer video whose visuals are word-precisely anchored to a pre-rendered voiceover. The molecule's core claim:

Every beat boundary snaps to a Whisper word boundary on the rendered VO. When the VO says "no scars," the NO SCARS slate is on screen for exactly that 0.80s.

This is achieved by rendering the VO first (not last), extracting word-level timestamps, then authoring one HTML hyperframe per script "station" (a sentence, a stat, a callout, a transition) with a deterministic window.renderAt(t) renderer driven frame-by-frame by Playwright. Beat durations are derived from Whisper timestamps, not authored arbitrarily.

Use when the user wants any of:

• Listicle ("5 things about X")
• Mechanism explainer ("how X actually works in 60 seconds")
• Stat-bombing / data ad
• Myth-buster / Q&A ("MYTH / FACT" pairs)
• Cost-math comparison ad
• Narrative monologue (founder story, patient testimony with VO)
• Document-reveal ("The Receipt" credentialing ad)
• Any 30-90s script-first shortform with mixed motion-graphics + B-roll
