  • Capture

    To extract footage from a tape format and transform it into digitized clips that can be manipulated in an editing program such as Final Cut Pro. Capturing is one of the first steps in the editing process. Footage is captured using different kinds of decks depending on the specific tape format. For example, footage shot onto a mini-DV tape will be captured on a different type of deck than footage shot onto a Betacam tape. For HD, since cards storing digital information is used instead of tapes, clips are imported rather than captured.

  • Color Temperature

    Depending on the source of light used to light a scene, every image has a color tint either on the reddish or blueish spectrum, called the color temperature. The color temperature of different light sources is measured using a scientific temperature scale called the Kelvin scale. A scene lit with natural, outdoor light, for example, will have a blue color temperature and that natural light has a high range of 5,200 to 12,000 degrees Kelvin, but will average 5,600 degrees Kelvin. A scene lit with incandescent lights will have a yellow or orange color temperature and those lights will have a low range of 2,800 to 3,400 degrees Kelvin, usually averaging 3,200 degrees Kelvin. While the human eye automatically adjusts in different light to see perceive white objects as white, videocameras must be adjusted in different light by setting the white balance. Proper adjustment of white balance will create images with accurate color ranges. Neglecting to set the white balance while shooting in different lighting conditions (moving from an indoor to an outdoor scene, for example) may result in an image appearing too blue or too red.

  • Continuity

    Most productions use a continuity supervisor to ensure that shots are set up to match one another. Keeping track of continuity is especially important when different parts of the same scene are shot on different days. Supervisors keep aware of continuity in terms of scenery details, blocking, use of props, actors’ costumes as well as camera angles and lighting schemes.

  • Contrast

    The relationship of dark or black parts of an image to light or white parts. A high contrast image will have deep blacks and very white whites. A low contrast image will have less range between dark and light, black and white and details may not be as apparent. The contrast of an image can controlled by lighting, how much light is used in a scene and how objects are lit. Contrast can also be controlled in film by using high contrast or low contrast film stock. The settings on a monitor on which an image is being viewed will also affect how one perceives the contrast of an image.

  • Contrast Ratio

    A measure used for video displays, the contrast ratio is the ratio of the brightest white level to that of the darkest color (black) in the image. A 1000:1 contrast ratio, for example, indicates that the brightest white is 1000 times brighter than the darkest black. Generally, the greater the contrast ratio, the better the image’s dynamics.

  • Cutaway

    An interruption of a continuous action with a shot of something else. Using cutaways allows editors to avoid jump cuts. It is usually followed by a cutback to the first shot. For example, if the main shot is of a man walking down an alley, possible cutaways may include a shot of a cat on a nearby dumpster or a shot of a woman watching from a window overhead. It’s most common use in dramatic films are to adjust the pace of the main action, to conceal the deletion of some unwanted part of the main shot, or to allow the joining of parts of two versions of that shot.
