The Quiet Metronome Sequence

Use [adult BlueHoodie character reference], [adult pianist reference] and [practice-room reference]. Create a 12-second cinematic scene: BlueHoodie pauses outside the practice room, leaves one folded card, walks away, and the pianist notices it through the window. Lock both adult identities and the single card; no instant virtuoso transformation.

Confirm required reference images and timing inputs are present before generating. Keep objects, identities, spatial relationships and light direction consistent. Render the clip when video generation is supported; otherwise supply a timed shot list, reference checklist and generation-ready prompt, labeled as a production plan. Do not claim rendered output without an actual file. Check the opening, transition and final frame against the stated counts and geometry.
