This glossary contains industry-standard terms and terms that apply to Autodesk
Composite.
1D LUT A 1D Look-up Table (LUT) is generated from one measure of gamma
(white, gray, and black) or a series of measures for each color channel. With a
pair of 1D LUTs, the first converts logarithmic data to linear data, and the second
converts the linear data back to logarithmic data to print to film.
1-point stabilizing A technique for removing the horizontal or vertical jitter
motion from a camera.
1-point tracking Tracking or stabilizing a single feature in motion, then
applying that motion to a second element, so that the two appear to be locked
together.
2-point stabilizing A technique for removing the motion or changes in
scale/rotation (zoom/roll).
2-point tracking A technique for tracking two features, using the relationship
between the two to track scale/rotation.
3D LUT A type of LUT for converting from one color space to another. It
applies a transformation to each value of a color cube in RGB space. 3D LUTs
use a more sophisticated method of mapping color values from different color
spaces. A 3D LUT provides a way to represent arbitrary color space
transformations, as opposed to the 1D LUT where a component of the output
color is determined only from the corresponding component of the input color.
In essence, the 3D LUT allows cross-talk, i.e. a component of the output color
is computed from all components of the input color providing the 3D LUT tool
with more power and flexibility than the 1D LUT tool. See also 1D LUT.
