multicam-skill

Sync and edit multi-camera footage of the same scene. Step 1 — sync timelines via audio cross-correlation (envelope-based, robust under low SNR). Step 2 — director-style auto-edit: pick the cleanest audio track, switch cameras on speaker changes / silence boundaries / motion beats, with optional crop-zoom virtual close-ups and picture-in-picture. Use when the user says "多机位", "multicam", "sync these camera angles", "match camera timelines", "auto-edit multicam", or provides 2+ video files of the same event from different angles.
