In video keying, the video signal that is inserted into the “hole” cut in the background video by a key signal.

A tool used to clean, manipulate, or modify captured motion data. You can use filters and filtering options to manipulate captured data according to your own specifications and to correct noisy or distorted motion capture data.

The process of cleaning, manipulating, modifying or otherwise tweaking captured motion data.

A Forward Kinematics system that lets you control individual pivot points on a model’s skeleton.

A method of moving a hierarchy (such as a limb) in which the lower elements of the hierarchy follow the motion of parent elements. For example, if you rotate the shoulder using forward kinematics, the upper arm, forearm, hands and fingers follow.

Frames per second.

See frame rate .

A single image at a specific point in time within an animation.

The individual picture image on a strip of film or a complete television picture made up of two fields.

A frame can be used as a unit of measurement.

The rate at which sequences of images are captured or displayed. The frame rate is usually measured in frames per second (fps).

Also referred to as an FCurve, a graphic depiction of an animated value. The time and value of the animated value displays on two axes: the vertical axis representing the value, and the horizontal axis representing the time.
