Match on action refers to a technique used when trying to give the impression of a passage of time in a scene. This is achieved by filming two shots from the same scene of action and cutting them together. These shots may have in fact been filmed hours apart… The character will often begin the action in one shot and carry it through into completion in the next; this distracts the viewer from noticing the jump in time or the fact that there is a “continuity error” between the two shots.
This effect can also be achieved by letting a character exit a frame in the first shot and then entering the frame in the same direction (exiting from left to right and then entering from the left)… This continues the rhythm of the screen direction.
