## Extracting to separate audio files (from YouTube)

We get the audio **from YouTube** so you can mix and match in the episode, full movie, and anywhere else:

1. Install [yt-dlp](https://github.com/yt-dlp/yt-dlp) (e.g. `winget install yt-dlp`).
2. Run **`scripts/download-soundtrack-audio.ps1`** to download audio from the playlists above into `assets/audio/playlist-1/`, `playlist-2/`, etc.
3. Run **`scripts/scan-audio-assets.ps1`** to register all tracks in **`data/audio-assets.json`**.

The **Soundtrack** page (`interfaces/soundtrack.html`) lists and plays these local files so you can mix and match. Use `placement` and `notes` in `data/audio-assets.json` to assign tracks to acts, segments, or time ranges.

## Placement

- **Episode 1 (60 min):** Map each playlist (or tracks within) to **acts**, **segments**, **stacks**, or **time ranges** as we cut the episode. Use `placement` and `notes` in `data/soundtrack-playlists.json` (playlists) and `data/audio-assets.json` (local tracks) to record where each goes (e.g. "Act 1 / Seed", "Stack 2 main story", "15:00–25:00").
- **Full movie:** Same idea — assign playlists/tracks to reels, acts, or key beats so the music gives the story its **pulse** and **dance**.
- **Storyboard / trading cards:** When building 30-second frames, we can tag a frame or a run of frames with a `soundtrack_playlist` or `soundtrack_track` id so the edit knows which music to lay under.
