# Long-form source analysis

A file is not considered reviewed merely because it appears in `source_inventory.json`.

For every video longer than 90 seconds:

```bash
python scripts/analyze_video_windows.py source.mp4 analysis/source_name --windows 60 --top 16
```

Required review:

1. Inspect the global contact sheet from beginning to end.
2. Open the top-ranked windows plus the first and last window.
3. Note recurring subjects, camera direction, lighting changes, and usable actions.
4. For each proposed B-roll cut, inspect at least one second before and after the window.
5. Reject cuts whose useful action starts late, leaves frame early, or is visually repetitive.

The numeric score is only a candidate finder. It cannot recognize narrative relevance, identities, logos, or whether motorcycles actually ride on a highway.
