The ability to key a subject as a regular chroma key, while using the border channel of the keyer to mix in the low luminance portions of the key signal. This allows a true shadow effect where any shadow in the key video appears as if it is in the background. All Ampex switchers have this feature, with variable shadow levels and densities (bdr adj and bdr lum respectively).
Industry:Software
A system of movable guides that automatically prevents the tape from contacting the recorder’s heads during fast forward or rewind modes of operation, thus preventing head wear.
Industry:Software
The amplitude ratio between a 2T pulse and a line bar is sometimes used as an indication of short time distortion. The results of this measurement can be described in units of K-2T or K-PB.
Industry:Software
A perforated metal plate which is mounted close to the inside of a color CRT display surface. This plate causes the red, green and blue electron beams to hit the proper R, G, or B phosphor dots.
Industry:Software
