# Mux Video (Optimal)

Skill Domain: Video Infrastructure & Delivery  
Primary Platform: Mux  
Target Level: Senior / Staff / Platform Architect  
Philosophy: Video is infrastructure. Reliability beats novelty. Analytics validate reality.

## 0. Prime Directive

Mux Video exists to deliver video correctly, everywhere, under real-world conditions — not to feel fast in development.

All decisions optimize for:
- playback reliability
- predictable latency
- measurable experience
- operational sanity

## 1. Canonical Mental Model

### What Mux Video Is
- Managed video pipeline: ingest → transcode → package → distribute → secure
- Abstracts FFmpeg complexity, CDN orchestration, ABR logic, and global delivery variance

### What Mux Video Is Not
- A CMS
- A player
- A social platform
- A monetization engine

---

## 2. Asset Model (Source of Truth)

### Assets
- Canonical representation of media
- Immutable once created
- Represent media, not intent
- Spawn many playback surfaces

### Design Rule
- One asset → many experiences

### Asset Lifecycle
- Ingest (upload or live record)
- Transcode
- Package (HLS / DASH)
- Expose via Playback IDs
- Observe via Mux Data

## 3. Control Planes (Separation of Concerns)

Mux controls:
- ingest stability
- transcoding
- packaging
- global delivery

You control:
- identity
- entitlements
- playback authorization
- business rules
- monetization logic

Failure to respect control planes causes:
- security leaks
- brittle playback
- un-debuggable outages

## 4. Ingest Strategy (Critical)

### On-Demand Ingest
- File upload (API or direct upload)
- Deterministic quality
- Preferred for premium content

### Live Ingest
- RTMP only (by design)
- Encoder quality determines everything downstream

### Live Rule
- If the encoder is unstable, the stream is already lost

### Encoder Best Practices (Non-Negotiable)
- Constant frame rate
