Continuity editing - Match-on-action

Match-on-action is when an action is started in one shot and continues in the next with the same energy. It can act as a distraction from accidental errors in the continuity such as items moving by them selves.

I filmed an example but it turns out my camera is broken but this video shows the concept well.

In one shot a page is being turned and in the next the action is still happening. To the audience it appears the action is happening continually rather than in two separate pieces.
