For your analysis, a clip of the legendary “long take” in Goodfellas. The shot begins across the street from the club, and follows the characters through the service entrance, down stairs, through the kitchen, into the club, to the table, ending on the stage. Total shot length: 3:10
A long take or oner is an uninterrupted single shot in a film which lasts much longer than the conventional editing pace either of the film itself or of films in general, sometimes lasting several minutes. In moving camera shots, is often accomplished through the use of a dolly or Steadicam. Long takes of a sequence filmed in one shot without any editing are rare, because of the complexity and coordination it requires.
The term “long take” is used because it avoids the ambiguous meanings of “long shot”, which can refer to the framing of a shot, and “long cut”, which can refer to either a whole version of a film or the general editing pacing of the film. However, these two terms are sometimes used interchangeably with “long take”. -Wikipedia
