A miniature cassette system originated by Olympus, allowing 30 minutes of recording per side on a capstan-driven tape, 1/7" wide, running at 15/16 ips.
Industry:Software
The decrease in level which occurs when a piece of equipment is inserted into a circuit so that the signal must flow through it.
Industry:Software
The luminance range that can be displayed on a theater projection screen is the ratio of maximum to minimum luminance achievable during projection of film. The maximum achievable highlight is determined by light-source output capacity, projection optical efficiency, the transmission of minimum film densities, screen gain, etc. The minimum is the luminance contribution from house illumination and other stray light, plus optical flare raising black levels, and the transmission of maximum film densities. Measured values in typical first-run theaters show luminance ranges of 500:1 to 300:1 (usually limited by house illumination).
Industry:Software
Line key effects, the video signal which is said to “fill the hole” cut in background video by the key source.
Industry:Software
A clone of an object. If you modify the original, all the instance objects are likewise modified.
Industry:Software
The luminance range, recorded may be reduced from the luminance range, scene intentionally and/or by the limitations of the recording system. Most systems have a maximum effective signal level limiting the high end, and noise limiting the low end. All of the scene that is of interest must be placed within these two limits by the choice of an appropriate transfer function. Some analog functions permit gradual transitions to overload and/or noise. Digital functions have inflexible limits imposed by the number of levels permitted by the bit assignments.
Industry:Software
A pickup pattern which is equally sensitive to sounds from all directions.
Industry:Software
A frame containing all the data representing an image, rather than just the data that has changed since the last frame. The first frame of every video file is a key frame; in addition, they occur throughout the file to refresh image quality and permit certain operations, such as random user access. Compare Delta Frame.
