We'll start our list with terms you'll often encounter when talking about the former.

• B-roll
  This is footage that's shot in addition to the main footage. For example, B-roll footage from a wedding might include audience reaction shots or footage of the venue. It's used to add interest and provide context to the main footage.
• Compositing
  The process of superimposing layers of pictures or video onto each other. Titles superimposed onto video footage is a good example.
• Montage
  An effective video editing technique where related clips or images are assembled in a sequence. Think of the training sequences in a "Rocky" film, and you see an example of montage.
• Raw footage
  As the name suggests, the footage captured by your cameras that will be turned into the final product. You'll usually have a great deal more raw footage than the finished video will show.
• Rendering
  This is the process of taking the edited video and producing it in a usable format. Different formats may be employed depending on the channel used for distribution. For example, a DVD will use a different format than a YouTube video.
• Voice-over
  Audio from an off-screen presenter or narrator, describing the action. This is recorded separately from the video footage and combined during the video editing process.

• Crossfade
  A fade-in of one video source as another that fades out at the same time. It's also commonly referred to as "dissolve."
• Cut
  Unlike a cross-fade, this is a sudden change from one clip to another.
• Cutaway
  In this editing technique, a shot of something different from the main subject is inserted into video, and then the main subject is returned to.
• Jump cut
  Sudden, abrupt jump in the action while the focus of the shot stays the same.
• Wipe
  A moving line or shape reveals the new shot as it moves across the frame. Often used to establish the passage of time or to set a new location.

• Chromakeying
  Also known as green screening. With chromakeying, an image is electronically added to the shot on areas that are color-keyed. A weather map in a news broadcast is an excellent example.
• Crawl
  A crawl is a set of graphics or text designed to move across the frame while other actions occur. This is often used in commercials or infomercials.
• Filters/filter effects
  Filters are digital effects used to change the look of the original footage. Colorizing, adding a tint, or using sepia are some examples of filter effects that can be added.
• Sound effects
  These are special sounds, usually prerecorded, that are added to the video soundtrack to augment or simulate real sounds.
