Pick list A list of frequently used tools and other elements that you can pick

process To create the final image or sequence of images using effects,
transitions, composite, or container clips in your sequence.
proxy A low resolution copy of a high resolution image, one for each frame.

provide low resolution stand in clips in a compositing environment so
composites can be quickly created. See also composition thumbnails.
Region of Definition (ROD) In Composite each image has a size and position
within a 2D reference plane also called the Image Reference Frame (IRF). The
Region of Definition (ROD) of an image is the rectangle enclosing that image
in the IRF. This rectangular region is always aligned with the main X & Y axes
of the IRF.
Region of Interest (ROI) A region (usually rectangular) that is determined
by the user in order to limit certain calculations. See also Domain of Definition
(DOD).
render The process of creating a final image or sequence of images from a
scene.
resolution The amount and degree of detail contained in the video image,
measured along both the horizontal and vertical axes by dots or lines.
RGB A color model that defines pixels according to red, green, and blue
channel values.
ROD See Region of Definition.
ROI See Region of Interest. See also Domain of Definition.
