Industry:Software
On the 4100 series, an RGB chroma key or a luminance key, as distinct from a composite (encoded) chroma key.

One thousand bytes. Actually 1024 bytes because of the way computer math works out.
Industry:Software
a) The four 8 by 8 blocks of luminance data and the two (for 4:2:0 chroma format), four (for 4:2:2 chroma format) or eight (for 4:4:4 chroma format) corresponding 8 by 8 blocks of chrominance data coming from a 16 by 16 section of the luminance component of the picture.
Macroblock is sometimes used to refer to the pel data and sometimes to the coded representation of the pel values and other data elements defined in the macroblock header. The usage should be clear from the context.
b) The screen area represented by several luminance and colordifference DCT blocks that are all steered by one motion vector. c) The entity used for motion estimation, consisting of four blocks of luminance components and a number of corresponding chrominance components depending on the video format.
Industry:Software
The specification of the direction a pattern moves as the fader is pulled. A normal pattern starts small at the center and grows to the outside while a reverse pattern starts from the edge of the screen and shrinks. Normal/Reverse specifies that the pattern will grow as the fader is pulled down, and shrink as it is pushed up. This definition loses some meaning for wipes that do not have a size per-se such as a vertical bar, however, this feature still will select the direction of pattern movement.
