A background image, video clip, or video feed to be displayed on the background plane in a scene.
Back plate can also be spelled as one word in other software products.
A chroma key feature that senses the color of the chroma key backing and replaces it with a complementary color. As a result, the two colors cancel each other. This eliminates the halo or fringing effect surrounding the foreground object in the chroma key.
A chroma key feature that senses the color of the chroma key backing and replaces it with an adjustable luminance level. This prevents the backing color from appearing in the chroma key.
A video generator that produces a solid-color output which can be adjusted for hue, chroma, and luminance.
A plane in a scene on which images, video clips, or video feeds are projected.
The default animation layer to which all other layers are merged when you plot an animation.

The process of automating a frequently performed task by storing commands in a script or “batch file”.
For example, batch load refers to the process of loading or processing more than one file with a single command.
The bits per second (bps) rate at which the information carrying capacity of a communication channel is measured.
In MotionBuilder, the position in which a character is weighted, wherein all of the character’s limbs should be in neutral positions, neither fully extended nor fully contracted.
A character animation file format that contains skeleton hierarchy information and motion data.
BVH, one of the most popular motion capture data file formats, is mainly used as a standard representation of motion capture of humanoid structures.
In MotionBuilder, a humanoid skeleton that stands on two legs, making contact with the floor using only the feet.
The memory in a graphic display device that holds a complete one-bit-per-pixel image.
The lowest transmittable luminance level that can occur during the active picture portion of a video signal. When viewed on a monitor this signal level is seen as black.
In MotionBuilder, any selection of nodes or sensors with captured data, a part or complete hierarchy of models with plotted data, or a Control rig that can be used to perform a motion blend.
In MotionBuilder, the connecting lines between the joints that compose an Actor skeleton.
In MotionBuilder, a 3D model that has a rigid skeleton and is covered by a mesh. The mesh contains a texture and body features that give the model a distinct appearance.
Rigid bodies that limit the area in which the eyes, eyebrows, and mouth of a face model can move in an Actor Face.
A part of a hierarchy or tree-based data structure where there is only one route between any pair of nodes. A node on a branch has only one parent.
Along with contrast, a property that determines the luminance of an object.
A file format for audio data that contains the minimum information – or metadata – considered necessary for all broadcast applications. It contains information such as timestamp and other metadata contained in the header file.
The Broadcast Wave Format (BWF) can be used for the seamless exchange of audio material between different broadcast environments and between equipment based on different computer platforms.
This standard audio format was created by the European Broadcasting Union as a successor to the WAV format. See the EBU-TECH 3285 document (Specification of the Broadcast Wave Format [BWF]) form the European Broadcasting Union.
An area of memory used for storing messages.
A texture that defines the height of bumps on a surface, on a per-pixel basis.
A texture that contains two direction vectors and is used to convey relief in a texture.
