In filmmaking, a pick-up is a small, relatively minor shot filmed or recorded after the fact to augment footage already shot. When entire scenes are redone, it is referred to as a re-shoot. Both types of shots usually occur after continuity, logic, or quality issues are identified during the film editing process. In other words, such shots occur months after the sets have been struck, the costumes and props have been stored, and all the cast and most of the crew have moved on to other projects. If the issues had been identified during principal photography, the director would simply have asked for another take. Therefore, the director and producer must carefully balance the substantial expense of reuniting key cast and crew members on set against whether pick-ups or re-shoots are absolutely necessary to fix plot holes (or worse) in the final cut.
News reporting uses the related but distinctly different concept of "insert" or "reaction shots". These differ from pick-up shots in that they are merely new takes made immediately after the original recording they are used to augment, while pick-ups or reshoots are made much later as an entirely separate recording session.
Local news stations typically send just one remote camera to cover a story, a practice called PSC, or Portable Single Camera. After recording an interview, if there is time (i.e., the reporter is not covering breaking news that must be broadcast immediately), the subject is then asked to "react to questions" and the camera records those additional shots. The reactions from angles other than the original shoot are then edited into the interview's final cut, which then looks less boring than single-angle shots of the interview subject.
