# Guided Promo Video

> End-to-end guided workflow for creating a promotional hype video. Extracts brand identity from the repo, generates beat-synced music, and produces a high-energy motion.dev composition rendered via Helios CLI. Use when making brand-aligned promo or hype videos.

You may be operating inside the brand's repository, or working from an external context.

Do not guess brand identity. Either analyze the codebase or research the provided URL.

------------------------------------------------------------
EXECUTION PIPELINE
------------------------------------------------------------

STEP 1 — Gather Context

⛔ STOP. Ask the user these two questions:

1. "Are we inside your brand's repository, or would you like to provide a URL (e.g. your marketing site) so I can research your brand online?"

2. "Would you like generated background music? If yes, you'll need an ELEVEN_LABS_API_KEY in your environment. You can get one at https://elevenlabs.io → Profile → API Keys."

Wait for the user to respond to both questions.

Do not attempt to read .env files or verify keys yourself.
Trust the user's responses.

If the user provides a URL, use it for brand research in STEP 3 instead of analyzing the codebase.
If the user declines music, skip STEP 4 and STEP 5.


------------------------------------------------------------
STEP 2 — Ensure Helios Runtime Dependencies

Install required packages:

npm install @helios-project/core @helios-project/renderer @helios-project/cli

You will render using DOM mode.

------------------------------------------------------------
STEP 3 — Extract Brand Intelligence From Repo

If the user provided a URL instead of a repo, fetch that URL and extract
the same brand signals from the live site. Skip codebase-specific items
(Tailwind config, design tokens, etc.) and focus on visible brand elements.

Analyze:

• Tailwind config or CSS variables
• Global stylesheets
• Design tokens
• Logo assets
• Favicon
• Hero sections
• Marketing copy
• CTA structure
• Product positioning
• UI components
• Existing motion usage

Construct internal brand profile:

• Core value proposition
• Target audience
• Tone of voice
• Visual density
• Primary palette
• Accent palette
• Typography character
• Emotional positioning

All creative decisions must align with this.

------------------------------------------------------------
STEP 4 — Generate Original Music (Skip if no music)

Use ElevenLabs with existing ELEVEN_LABS_API_KEY.

Generate instrumental track matching:

• Brand tone
• Emotional arc
• Target runtime

Save audio locally.

------------------------------------------------------------
STEP 5 — Analyze Audio With ffmpeg (Skip if no music)

Extract:

• BPM
• Beat timestamps
• Downbeats
• Energy peaks

Create beat timing map.

All animations must align to this timing map.

------------------------------------------------------------
STEP 6 — Read Motion Design Rules

Before producing the creative specification, read and internalize:

skills/guided/motion-design-rules

Every rule in that skill is mandatory for this composition.

------------------------------------------------------------
STEP 7 — Produce Creative Specification

You are a senior creative director and motion systems architect designing for Helios using motion.dev.

Input example:
make a 15 second hype video

Output:

• One structured creative specification
• Wrapped in a single code block
• No explanation outside it

The specification must include:

• Duration
• Aspect ratio
• Brand summary
• Motion language
• Beat synchronized scene breakdown
• Exact timestamps
• Voiceover
• On screen text
• Visual composition
• Explicit motion.dev animation behavior
• Transition logic
• Layering order
• Audio direction
• Asset requirements

Use motion.dev compatible terminology only.

------------------------------------------------------------
STEP 8 — Implement DOM Based Helios Composition

Using the creative specification:

Create a composition.html file that:

• Uses HTML + CSS + motion.dev
• Implements animations using WAAPI / CSS / motion.dev
• Aligns animations to beat timestamps
• Includes generated audio file
• Has exact duration

Expose Helios runtime:

```js
import { helios } from "@helios-project/core";

window.helios = helios;

helios.bindToDocumentTimeline({
  autoSyncAnimations: true
});
```

Requirements:

• window.helios must be defined
• helios.bindToDocumentTimeline() must be called
• autoSyncAnimations: true must be enabled
• All CSS and WAAPI animations must sync correctly
• No randomness
• Deterministic timing

------------------------------------------------------------
STEP 9 — Render Using Official Helios CLI (DOM Mode)

Render with:

npx helios render ./composition.html -o output.mp4

Requirements:

• Correct aspect ratio
• Correct duration
• Audio attached
• CSS and WAAPI fully synchronized
• High quality MP4 output

Output file must be:

output.mp4

------------------------------------------------------------
RUNTIME RULES
------------------------------------------------------------

If duration ≤ 15 seconds
Prioritize punch and clarity.

If no duration specified
Default to 30 seconds.

Never restate the original prompt.
Never explain reasoning.
Creative specification must be output inside a single code block only.
