To magnetise by being put within the magnetic influence of a magnetic field.
Industry:Software
The maximum separation in time which can be given to regularly spaced instantaneous samples of a wave of bandwidth W for complete determination of the waveform of the signal. Numerically, it is equal to 1/2 W seconds.
Industry:Software
Editing using media like tape, in which material must be accessed in order (e.g., to access scene 5 from the beginning of the tape, one must proceed from scene 1 through scene 4).
See Nonlinear Editing.
Industry:Software
A successful motion path has two components: geometry and timing. The geometry is created by choosing keyframes. The timing of the path is more complex, and can be affected by the geometry.
Intuitively, the timing of a path is simply the speed of motion of the object as it moves along the path. Since PictureMaker starts with keyframes and creates in-between positions, PictureMaker determines the velocity by deciding how many in-betweens to place between each keyframe (and where to place them). Several methods can be used to determine velocity along the path. a) Place frame evenly between all keyframes. Closely placed keyframes will correspond with slow moving parts of the path.
b) Specify a relative velocity at selected keyframes, and specify correspondences between any keyframe and a frame in the final animation.
Industry:Software
A number describing the loss of vertical resolution due to interlace, in addition to any other loss. It is sometimes confused with the Kell factor.
Industry:Software
The property of a magnetic material that causes variations in the residual flux density of a tape to occur with temperature, time, and/or mechanical flexing. Magnetic instability is a function of particle size, magnetization, and anisotropy.
Industry:Software
When time-varying information is sampled at a rate R, the highest frequency that can be recovered without alias is limited to R/2.
Aliasing may be generated by under sampling temporally in frame rate, or vertically in lines allocated to image height, or horizontally in analogue bandwidth or in pixel allocation. Intermodulations prior to band limiting may “preserve” some distracting effects of aliasing in the final display. Note: Sampling at a rate below the Nyquist limit permits mathematical confirmation of the frequencies present (as for example in a Fourier analysis of recorded motion). If the sampling window is very small (as in synchronised flash exposure), however, it may become a subjective judgement whether strobing is perceived in the image for motion approaching the limiting velocity (frequency).
Industry:Software
A modern method of addressing the display memory.
The display memory (in the IBM PC world) was originally located in a 128-Kbyte area from A000:0 through BFFF:F, too small for today’s display systems with multi-megabyte memories. Linear addressing allows the display memory to be addressed in upper memory, where a large contiguous area is set aside for it.
Industry:Software
Alternate raster lines are scanned producing an odd field (odd-numbered lines) and an even field (even-numbered lines). An interlace of 1:1 implies vertically adjacent lines comprise the field.
Industry:Software
The technology and process of recording audio/video information using magnetism as the medium for storage of information. The term is often used to mean the process/capability of both recording and reproduction/playback.
