If scope, movietone, full aperture, or 70mm films are projected slightly out of frame, if the projectors' aperture plates are overcut, or if a film has sloppily made negative splices, white flashes will appear at the top and/or bottom of the frame at every shot change (sometimes several dozen times over the course of a reel!). Care must be taken to monitor framing closely, as the exact location of these splices can change from reel to reel depending on how the film was printed.

The standard aspect ratio for scope films was eventually changed from 2.35:1 to 2.39:1 to account for thicker splices, which is helpful but does not fully eliminate the problem.
