Basic Editing: Straight Cuts, Split Edits & Match-on-Action

Match on Action

        A Match on Action is where an action is filmed showing it from numerous angles, but not repeating a part. For example, a student wants to prove to their teacher they can do a Match on Action. They film someone going through a door, from one side of the door and then the other. The student opens the door fully on the first take, then on the second the door is still being opened. This will be a poorly executed Match on Action.
        This is a scene from The Hobbit: An Unexpected Journey, where the dwarves make many Match on Actions throwing and catching plates and so forth. I hope this has helped! :)

Straight Cuts and Split Edits

        Cuts in films can be either L cuts (split edits) or straight cuts. In a film timeline, the video is above the audio, so an L cut would separate the two, overlaying audio onto a separate video. Most cuts are straight cuts, which means the video and audio change at the same time. L cuts can work backwards, meaning the video stays on longer whilst the audio changes first. In an L cut in the shape of an L, the video changes whilst the audio remains the same for a small while. The video below describes L cuts:
