Setup, calibration and show-day notes. If something here is wrong or unclear, tell us — these pages are written from real rooms and they improve when they get corrected.
Before the day
- Confirm the camera can lock exposure. This is not optional. See how it works for why.
- Confirm you can mount it high, with a view of the whole seating area.
- Confirm there will be light on the audience. A crowd in blackout is invisible to a camera.
- Agree where the game sits in the run of show, and who is talking while it happens.
Setting up
- Mount and aim the camera. Frame the seating area and as little else as possible.
- Lock exposure, white balance and focus.
- Capture the empty-room reference before anyone sits down, if you can.
- Choose the detection mode the title calls for — most use posture.
- Calibrate with the actual audience: crouch, capture; stand, capture.
- Set Response. Start in the middle, adjust once you have seen the room react.
On the day
- Recalibrate after the room fills. A half-full room and a full one are different pictures.
- Recalibrate if the lighting state changes materially between calibration and play.
- Give the room one instruction, not three. “Stand up to go up” is enough to start.
- Expect thirty awkward seconds before it clicks. It always clicks.
Troubleshooting
The game reacts when nobody moves
Almost always auto-exposure. Lock it. If it is already locked, check for a moving light source in frame, or a screen visible to the camera.
Tiny movements swing it wildly
The calibrated range is too narrow — usually a camera that is too low or too close. Raise the camera, crop the analysis to the seating area, and recalibrate.
It barely responds
The opposite: the captured range is too wide, or Response is too low. Recalibrate with a genuine crouch and a genuine stand — a polite half-crouch produces a useless range.
Half the room is not playing
Normal for the first minute, and not a software problem. Whoever is on the microphone matters more than any setting here.
It worked at rehearsal and not at the show
Something in the picture changed: lighting state, camera knocked, or the room filled up after you calibrated. Recalibrate.
