Match On Action

Match on Action is used to show interaction between two characters, for example it could be used to show an object being passed between characters where different shots are joined together.
The important thing to remember is where there is a cut in the middle of any action or movement in the frame, the action must be kept continuous to avoid disruption to the storytelling.

In this extract from Doctor Who, match on action is used to show the object being thrown from one character to another using different shots.
