About Noddy

A nod shot, noddy headshot or noddy is a type of camera reaction shot used in recorded news or current affairs interviews. They consist of nods and other similar "listening gestures" made by the interviewer. If only one camera is available at the interview site, then these shots are recorded after the actual interview takes place. The shots are spliced into the interview during the editing process to mask any cuts that have been made. This editing technique is almost universally "read" by audiences as expressing realism and therefore creates the illusion of a seamless dialogue in the interview.
