Unique-frame deduplication

For a 4-second smoke PDF, only ~14 unique composites are rendered versus ~129 timeline frames at 30 fps—roughly an order-of-magnitude reduction in static-camera mode.

Parallel workers

OCR and frame compositing scale with CPU core count. AAC re-encoding overlaps with video rendering.

Camera mode trade-off

Smooth pan-and-zoom requires per-frame compositing and scales with total frame count—ideal for short demos, heavier on long documents.

Correctness

Eleven automated tests cover text indexing, cue timing, highlight mapping, and camera planner behavior.
