## What it does

This skill builds a short hype piece that lands like a showreel. Something hits on the beat every half-second, yet it never reads as random cuts, because one shape carries the eye across every transition: a spark stretches into a line, the line floods the frame into the next background, a full stop detaches and becomes the ball the next scene is built around.

The mechanics: you write a single HTML page that can render any frame from a time value, then render it to MP4 with motion blur and a synthesised soundtrack. The skill asks for the whole brief in one message — product, the one thing viewers should remember, brand colours and fonts, 16:9 or 9:16, length, music, optional direction. Only the product is required; anything left blank it decides itself and tells you what it picked. Hand it a website URL and it reads the page first, so UI labels and taglines use the product's real wording.

Default length for this style is 15 seconds at 128 BPM, range 12–20. The structure is 6–8 scenes of 1.5–3 seconds on a 120–140 BPM grid, with a HUD frame, scene counter and timecode. Made-up facts are off the table: stats, ratings and testimonials come only from the brief or the site, otherwise you get relative bars and skeleton lines. A logo goes in only if the user supplies the file or it is their own product.

# High-energy explainer

A 12–20 second hype piece that hits like a showreel. Every half-second something lands on the beat, but it never feels like random cuts, because **a shape carries the eye across every transition**: a spark becomes a line, the line floods the screen into the next background, a full stop detaches and becomes the ball the next scene is built around.

You write it as one HTML page that renders any frame from a time value, then render it to MP4 with motion blur and a synthesised soundtrack.

## Step 1: Get the brief (one message, then go)

Ask everything in **one** message, then work on your own. Only the product is required; for anything left blank, decide yourself and say what you chose.

1. **Product**: name, and what it does in a few sentences. A website URL is even better.
2. **The one thing** the viewer must remember (e.g. "type an idea, get a live app").
3. **Brand**: colours, fonts, logo file, or "use the website". If none, use the default palette below.
4. **Format**: 16:9 (1920×1080) or 9:16 (1080×1920). Default 16:9.
5. **Length**: default is given below for this style.
6. **Music**: their own track (a file path), or let you synthesise one. Default: synthesise.
7. **Direction** (optional): scenes they want, a tagline, a call to action, anything to avoid.

If they gave a URL, read it (web fetch) for the product's real wording, features, colours and font names before writing anything. Use their real words for UI labels and taglines.
```
