An alias caused by unfiltered sampling in the vertical direction by scanning lines. Vertical aliasing is frequently noticed when reading vertical resolution on a resolution chart. The wedge-like lines become finer and finer until they reach the limit of the vertical resolution of the system, but then they may appear to widen or to change position. This is caused by lines on the chart sometimes falling between scanning lines and sometimes on them. In a properly filtered television system, detail finer than the vertical resolution of the system would be a smooth blur.

A variable-width border that occurs at the edges of a wipe pattern. The border is filled with matte video from the border matte generator.

In real life, when an object at rest begins to move, it starts slowly. Similarly, when an object changes its speed, or direction, it rarely does so instantaneously, but rather makes the change gradually (that’s one reason we use splines to describe motion paths in computer animation). In order to create satisfying animation, it is important to be sensitive to the rate at which objects change their direction and speed; these factors are the most expressive component of path animation, like tempo and dynamics in music. In particular, the term slow-in/slow-out refers to an object at rest which gradually accelerates, reaches a final velocity, then slows and stops.
Industry:Software
The ideas of electronic video rental could be realised through the techniques of time compression: video data compression is used for “less than real time” delivery of video/audio as opposed to real-time, compressed video in “normal” distribution applications.
Industry:Software
The parameters associated with raster scanning of a computer display, camera, or video recorder. Denoted by the total line count, field rate, and interlace ratio.
Industry:Software
This usually implies an audio system with more than two channels of information. The additional channels provide “ambiance” or sound information that is happening somewhere other than from the left or right speaker.
Industry:Software
A) Refers to the blanking signals which occur at the end of each field.
b) The time during which the electron beams of an output device are turned off and positioned to the upper left edge of the display.
c) A video synchronising signal that defines the border or black area at the top and bottom of the display and, in a CRT, hides (blanks out) the electron beam’s retrace path from the bottom to the top of the display.
Industry:Software
The hardware (and software in AVC) package which expands the standard pattern system to include rotary wipes, and rotating patterns (and matrix wipes in AVC).
Industry:Software
RealAudio is an on-line audio software platform, from the company Progressive Networks, dedicated to audio links on the Internet via 14.4 kbit/s, 28.8 kbit/s or faster connections. RealAudio software features a player, a server, and development tools, and is available for Windows, Unix, and Apple Macintosh environments.
