Two actions at the same time

Split Screen are an editing tool to make a scene look different and to show either more than one action at the time, or the same action, but from different camera shots. To me personally, I hate to miss out on anything, so I usually end up rewinding the scene, and focus on only one scene at a time.

The technology made split screen a lot easier to make, but 20 years ago, it was a little bit more complicated. They had to film the actions separately, and replicate both images on the same negative.

In a DVD special features, where the directors and actors are being filmed to talk about a movie's special effects and behind the scenes, usually there will be a smaller screen to show what they are mentioning and to help the viewers to visualize better.

Often also, the split screen is used to show a telephone conversation between two persons.
