Lock a click track before a scoring session

Reinforce music-prep order from scoring-stage training. Downbeat is not called until tempo map, streamers, and the click are locked to picture.

1. Confirm the picture version.
2. Confirm the start-of-picture timestamp.
3. Lock the tempo map and click to that picture.
4. Check streamers and punches against the cue list.
5. Play a silent bar for the orchestra to hear the click.
6. Record only after the conductor and mixer confirm sync.
7. Do not ‘fix it in the take’ if the click is off by a frame.
