Shot - Reverse Shot

Shot reverse shot also known as countershot is a film technique where one character is shown looking at another character (often off-screen), and then the other character is shown looking back at the first character. Since the characters are shown facing in opposite directions, the viewer assumes that they are looking at each other.

Match On Action

Match On Action means that when something happens in the scene then when there is a cut, the same piece of action must be going on. This is an example of continuity editing and is very important in helping the audience continually understands exactly what is happening.
