Flash cut
In the United States, some telephone area codes were split or overlaid immediately, rather than being phased in with a permissive dialing period.An example is telephone area code 213, which serves downtown Los Angeles and its immediate environs, split in January 1951 into 213 and 714 all at once.A flash cut can also define a procedure in which multiple components of computer infrastructure are upgraded in multiple ways, all at once, with no phase-in period.In film, an extremely brief shot, sometimes as short as one frame, which is nearly subliminal in effect.Also a series of short staccato shots that create a rhythmic effect.
