noddy
n.— «After the interview is finished, the camera is then turned onto the interviewer who asks some of the questions again and gives a series of “noddies,” that is, reaction shots, nods, smiles, or expressions of sympathetic listening. These are to disguise later edits in the interviewee’s speech. When section of this speech is edited out, the cut is disguised by inserting a noddy,” thus hiding the fact that any editing of the speaker’s words has occurred. Without the “noddy,” the visuals would show an obvious “jump” that would reveal the edit.» —by John Fiske Television Culture , 1987. (source: Double-Tongued Dictionary)
