The call sequence
A standard sync-sound take goes like this on a US set:
- 1st AD: "Picture's up." (Final warning, everyone clear.)
- 1st AD: "Roll sound."
- Sound mixer: "Sound speed" or "Speed."
- 1st AD: "Roll camera."
- Operator or 1st AC: "Rolling" or "Camera speed."
- 2nd AC: "Marker," and claps the slate.
- Operator: "Set."
- Director: "Background action," if any, then "Action."
The PAs repeat "rolling" on channel 1 right after step 5, and some shout it outside the stage door. On soundstages, a red light and a bell or buzzer at each door signal the same thing. When the take ends, the director calls "Cut," and the PAs relay "Cut" so lockups can release.
What a lockup does during rolling
A lockup is a PA posted at a door, a hallway, or a sidewalk to stop people and traffic from walking into frame or making noise. When the PA hears rolling, they hold pedestrians politely ("We're rolling, just a minute please"), hold crew coming from base camp, and ask the delivery truck to wait. When they hear cut, they let everyone through. On a city street, the permit terms decide how long a production can hold the public, and police or traffic officers may control the actual stopping.
Things that go wrong
A PA far from set who misses "cut" holds pedestrians for five extra minutes and draws complaints. The fix is to repeat every call you hear and to ask "Are we still rolling?" if the radio's quiet.
Talking on channel 1 during a take is a common new-PA mistake. The 1st AD needs the channel for safety, and a keyed walkie near a microphone can be picked up.
People reacting to "rolling" when it's a rehearsal. If the 1st AD says "rehearsal, not rolling," sound usually doesn't need full silence, but camera may still need stillness in the background.
Related calls
"Rolling reset" or "keep rolling" means the camera keeps recording while everyone goes back to one for another take without cutting. "Hold the roll" means wait, something's wrong. For how each department relays these, see walkie channels, and for the calls just before this one, see last looks.
