Research: Match On Action

Matching on action refers to a film editing technique where the editor cuts from one shot to another view that matches the first shot's action. Although the two shots may have actually been shot hours apart from each other, cutting on action gives the impression of continuous time when watching the edited film. By having a subject begin an action in one shot and carry it through to completion in the next, the editor creates a visual bridge which distracts the viewer from noticing the cut or noticing any slight continuity error between the two shots.
A variant of cutting on action is a cut in which the subject exits the frame in the first shot and then enters the frame in the subsequent shot. The entrance in the second shot must match the screen direction and motive rhythm of the exit in the first shot.

Match On Action is a continuity technique that uses jump-cut editing in order to give the viewer the impression of one continuous take.

It's always important to make sure that action in one take matches in the next, like the speed of a person walking for example.

Also, to keep continuity, if a subject leaves on the right, they must enter on the left, and vice versa.
