# Route: music-to-video

- **Input:** A music track, a video whose audio becomes the track, or a track generated from a mood brief — with no narration or website capture. User images or videos are optional, so a complete video needs zero supplied assets.
- **Output:** A beat-synced MP4 driven by a deterministic beat/energy map (`audiomap.json`). It may become a lyric video, slideshow, visualizer, or kinetic promo without changing pipelines.
- **Triggers:** "make a video for this song", "beat-synced video", "lyric video", "music visualizer", "kinetic promo to this beat".

## Interview

- **Must-haves:** the **music source** — a track file, a video to pull audio from, or generate one from a mood description · **destination → aspect**.
- **Deferred (announce):** brand (font + palette) and the genre feel are chosen at its Step 3 by design — they emerge from the track's analysis, not from a question up front.
- **Pitch round:** `message` — the visual concept riding the beat grid (lyric treatment, montage story, kinetic type); brand and genre feel still land at Step 3.
- **Run-shape:** both.
