LUT A Look-up Table (LUT) is an ASCII file that describes specific pixel
values used for image data conversion both on import and export. For example,
you can use a LUT to convert a 10-bit logarithmic film image to a 16-bit linear
image on import. You can use two kinds of LUTs: 1D LUTs and 3D LUTs. See
1D LUT, and 3D LUT.
masking The process of hiding a region of an image. You can use masks to
remove the area outside the mask shape and keep the area inside the mask
shape, or you can use masks to remove the area inside the mask shape and
keep the area outside the mask shape. Pixel Masking lets you temporarily
isolate specific areas of the footage. You can apply effects to the selected area
of an image without affecting the rest.
material A material defines how a layer interacts with lights to define how
a scene is rendered. Each layer must have a material associated with it, but
many layers can share a single material.
matte An image used to define or control the transparency of another image.
When you pull a key, a matte that defines the transparency of the front source
is generated. There are several types of mattes. See also keying, external matte,
garbage matte, static matte and traveling matte.
metadata Information embedded in the image attained through tags that
further describes the image.
motion blur A digital effect that simulates the blur of fast-moving objects.
multiple-point tracking Multi-point tracking tracks as many features as you
want. You can apply the stored motion to various elements, such as the center
point of an object. For example, you could track a halo over the head of a
person in a clip. Assume that in the clip a woman tilts her head and advances
toward the camera. You would want the halo to reflect the position, scaling,
and rotational changes of the tracked features on the woman's head.
mute To turn off a node.
node An element for connecting a composition in a dependency graph.
There are several types of nodes, including input, output, group, tool, and
super tool.
NTSC National Television Standards Committee. The committee that
established the color transmission system used in the United States, Canada,
Mexico and Japan. Also the broadcast standard for North America. The NTSC
standard uses 525 horizontal lines per frame with two fields per frame of 262.5
lines. Each field refreshes at 59.94 Hz. See also PAL, and SECAM.
object Any element in a 3D scene, such as lights, camera, and surfaces.
