Section 2 — Concepts
Default Keyframe
An important E-MEM concept is the Default Keyframe. A Default Key-
frame is a standard collection of effect settings. When the work buffer is
cleared, the initial settings it receives will be those defined as the Default
Keyframe. The Default Keyframe does not alter effect registers and does
not change current source selections or panel delegations, which should
only be changed directly by the operator (
Figure 42 ).
Figure 42. Default Keyframe
The operator can define exactly what these default settings should be (Suite
Preference), and these settings can be stored and reused to meet varying
requirements. A separate set of factory default settings also exist that
cannot be changed, but may be loaded to the Default Keyframe and then to
the work buffer, typically for system test and initial system installation.
Source Memory
Source memory is a Zodiak system feature that retains the last settings of
keying and video processing parameters used for each source on each bus.
Source memory permits the operator to hot cut from one key to another
and retain the settings for each source. Source memory keying settings
include Clip, Gain, Mask, and many other parameters used for various
keying functions. Video processing (proc amp) settings include Lumi-
nance, Chrominance, DC Offset, etc. The source memory feature can be
turned on and off by the operator.
