skills/talking-head
# Talking-Head Video Processing Process direct-to-camera videos with sentence-level precision, rolling captions, and multi-format output. ## Full Pipeline Overview ``` Raw Video (47+ min) ↓ smart_chunk.py Chunks (2.5-3.5 min) ↓ mlx_transcribe.py --word-timestamps Transcript (word-level timestamps) ↓ sentence_split.py (precise cuts, no overlap) Sentence Clips (~10s each, frame-accurate) ↓ analyze_script.py (RECALL-FIRST) Topics with complete arcs (hook → elaborate → conclude)

Detect silence regi
