Build a premium, fully-animated PRODUCT-DEMO / launch motion-graphics video from a written brief about your product — the "one seamless film" style: scene-by-scene motion graphics with camera moves, real UI mockups, and full sound design, rendered from HTML+CSS+GSAP to MP4 via HyperFrames. Use whenever someone wants to "make a product demo video", "launch video", "animated walkthrough", "hype/demo reel for <product>", an animated feature or flywheel story, or to add any of these set-pieces: a notification/feedback FLOOD of bubbles, real photos of people as circular avatars, a GitHub/changelog/release mock, a "context accumulates" web of connecting cards, a UI element that MOVES + recolors with the camera following it, a contributors wall, an explosion-into-logo endcard, count-up numbers, 3D panel fly-ins, or camera zoom/dolly transitions. ALSO covers full SOUND DESIGN — picking the right SFX for each animation and placing them (see docs/SOUND.md + the bundled sfx/ kit + templates/). The techniques come from a real launch film (https://youtu.be/spaS08Udkyk), but this is a GENERAL-PURPOSE kit: do not copy that film's story. Ask the user what THEIR product does, pick a story arc that fits it, and re-skin the brand tokens. The bundled example uses deliberately generic placeholder copy. For single-concept explainer reels or talking-head edits this is the wrong tool.

# DemoStudio — the playbook

You are building a **premium product-demo motion-graphics film**: one seamless timeline of
full-screen scenes telling the USER'S story (pick an arc that fits their product, e.g. problem →
product → payoff, before → after, or many inputs → one output; do not default to a feedback-capture
loop), with camera moves between beats. The whole video is **ONE self-contained HyperFrames composition**
(`index.html` = HTML + CSS + GSAP) that renders to MP4, then a single SFX track is muxed on.

**Start from the example:** `example/index.html` is a compact, commented, working scaffold that
shows the whole architecture (paused timeline, 3 scenes, a camera push, a flood, an endcard). Read
it first, then grow it into the real thing scene by scene.
