How do they do recordings in a studio (say Coronation St for example) when 3 actors or so are in the one room and each of them is filmed in a 'head and shoulders shot', after saying their lines, the camera flicks to the next actor when they begin delivering their lines?
What I mean is, do they stop recording or do they press some sort of button that will flick to the next camera to film the actor whilst still recording/rolling?
The sound also seems to stay intact i.e. when an actor says their line and whilst saying it, camera pans to another actor whilst their voice is still going at the same time. It's almost like they don't stop recording?
Very confusing stuff!!

When making a film they generally film shots separately and the other actor doesn't even have to be there.
TV generally will have several cameras following the actors simultaneously.
Assuming you are referring to multi-camera television shoots, electronic rather than film (where scenes or sequences are recorded using several video cameras and cutting between them in real time) the piece of equipment used is called a vision mixer (UK) or video switcher (US). I was going to launch into a detailed description but this link does most of it for me:

Isn't the internet wonderful?
P.S: I operated various vision mixers for many years, so if you have any specific further questions......
and another point is budget. In the American series LAW AND ORDER, they use sometimes just one camera for the interior of the police office. The technique they use to cover all the characters dialogue, is scanning/panning. eg actor one will be facing camera, and says his words as actor two enters from screen right, into frame. Camera follows actor one as he moves left, as actor three enters from screen left the camera leaves actor one and fixes on actor three, who joins actor two for dialogue, as actor four enters into frame from right to left saying his words as he moves across frame, camera picks up on him and follows as he exits frame to fix on actor five entering the office door. He walks toward camera......and so on, just like a ballet, choreographed and marked for a whole scene, which without anything going wrong can be done and dusted in minutes. Saving the expense of having more than one camera and crew. Its all down to cost these days.
