Duration sync is mechanical: real voice duration wins; silent frames keep estimates; never hand-edit synced durations.
Check the music against the final cut before assembly. A library track can match the requested mood but open on a quiet build that drains the first seconds of a short launch video. Compare the opening with later five-second sections; when a later section has a stronger, musically clean start, trim from there and keep a short fade-in plus a longer fade-out. If frame or narration timing changes, redo this check against the new final duration so the music never ends early or leaves silence at the tail.

`node <SKILL_DIR>/scripts/frame-packets.mjs --project "$PROJECT_DIR" --storyboard "$PROJECT_DIR/STORYBOARD.md"`
