K

Kelvin, the unit of measurement used for absolute temperatures and color temperatures.

KEM

A brand name for a common 'flatbed' film editing machine. (Film Editing)

Key

Also called key source or key cut. A signal that can be used to electronically "cut a hole" in a video picture to allow for insertion of other elements such as text or another video image. The key signal is a switching or gating signal for controlling a video mixer which switches or mixes between the background video and the inserted element.

Key bus

A video switcher crosspoint bus used to select key sources (hole cutters) and/or key fills. Signals available to the key bus are typically the same sources and fills that are supplied to the other switcher crosspoint buses plus additional external key sources and fills.

Key channel

A channel of a digital picture manipulator that is used for manipulating key signals while the corresponding key fill video is manipulated by another channel.

Key frame (keyframe)

An effect that has been stored in memory, similar to a snapshot photograph. Individual key frames can be strung together to create an overall key frame effect, which is similar to animation.

Key frame effect

An overall effect consisting of a series of snapshots called key frames. When the key frames are replayed, the machine (switcher, DPM, etc.) automatically and gradually dissolves from one key frame to the next. A process called inbetweening defines what happens between key frames. The result is a moving animation effect.

Key Grip

The chief grip who works directly with the gaffer in creating shadow effects for set lighting and who supervises camera cranes, dollies and other platforms or supporting structures according to the requirements of the director of photography. (Production)

Key Light

The main light on a subject. (Lighting)

Key Numbers

Numbers placed on the edge of the film stock by the manufacturer as a unique identification point (35mm - every 16 frames: 16mm - every 20 frames). (Film Editing)

Keyer

An electronic circuit that creates a control signal to control a video multiplier based on selective information contained in a video signal.

Keylines:

Lines on mechanical art that show position of photographs or illustrations.

Kick

An object with a shine or reflection on it from another object. (Grip/Lighting)

Kiss

A light that gently brushes a subject. (Lighting)

Kiss die cut:

To cut the top layer of a pressure sensitive sheet and not the backing.

Knock out:

To mask out an image.

Knockout

When a page object overlays another, the image colour in the top object can be set to knockout so that the lower object does not print ink over the area that the top object covers. If this is done the colours of the two objects are not trapped, they butt fit, so any misregistration in the print process will show.
