Source Memory

used key memory settings for that key mode will be applied to the key cut
signal. This organizational structure allows source memory to retain dif-
ferent settings for the same source, and it also accommodates split keys.

Because each source on each bus has its own source memory, different set-
tings can be used for the same source on different buses. For example,
Camera 1 on M/E 1 Key 2 can be set up as a chroma key. At the same time,
Camera 1 on M/E 1 Key 3 can be set up as a luminance key with a black
and white proc amp setup. Calling up that same source on different buses
provides different keying effects.

Different source memory settings are retained for the different key modes.
These different settings can be applied to the same source on the same bus,
as needed. For example, a camera source on M/E 1 Key 1 can be setup for
both a chroma key and a preset pattern. The operator can choose the key
type for that source as the session requires. Choosing a chroma key will
recall its latest chroma key source memory settings, which can then be
altered without changing the preset pattern source memory settings.
Choosing preset pattern on that same source and bus later in the session
will recall its unaltered source memory settings.

When a key split is performed a different key cut signal is selected for use.
On a Zodiak system with source memory on, that new key cut source’s key
mode and keyer settings will be used for the split key (

Figure 45

). This is

different from the Grass Valley 4000 switcher, which associated its source
memory only with the key fill signal.
