A look at the code

# Detect scenes using content-based detection (best for hard cuts)
videos.add_computed_column(
    scenes_content=videos.video.scene_detect_content(
        threshold=27.0,  # Lower = more sensitive
        min_scene_len=15,  # Minimum frames between cuts
    )
)

# View detected scenes
videos.select(videos.title, videos.scenes_content).collect()
