Operator’s Guide (for Imagestore 750s)
Working with DSKs
All Imagestore 750s provide 4 DSKs (downstream keyers). A key is a video effect that usually
consists of two video sources, fill and key. The keyer mixes the fill, masked by the key, with
upstream program video. In some cases, key values are derived from the luminance of the key’s
fill values. A key can be partially or fully opaque. It is possible for an operator to control the way
the key values mask the fill values.
The Imagestore 750 performs video effects in a configurable order:
DSK 1 is upstream of DSK 2, which is upstream of DSK 3, which is in turn upstream of DSK 4.
The DVE (if present) can be placed before DSK 1, before DSK 2, or before DSK 3.
where the effects to the right have visual priority over effects to the left. We say the effects to the
right are
downstream and effects to the left are upstream . Your panel’s effect buttons, if any,
might occur in any order. Your panel might not have buttons for all video effects.
S In an Imagestore 750 configuration, some or all DSKs can be disabled.
S The LGK-3901 and ISM-3901 have 5 DSKs, and no DVE.
S The DSK-3901 has 2 DSKs, no DVE, and no internal storage audio or video clips.
Keys can be external or internal. The Imagestore 750 supports up to 3 external key sources.
Internal keys are generally called clips, stills, or animations. The number of internal keys is poten-
tially large and is limited only by available memory.
The use of DSKs is affected by certain transition options. See Transition Options on page 110 for
more information.
Performing Key Transitions
You can transition any combination of video effects (including up to 4 DVEs and up to 4 DSKs) to
program output.
Follow these steps to transition one or more keyers to program output:
1 Use the ‘DSK Browser’ menus to select keys and perhaps change their settings. The names of
the selected keys become visible on the associated DSK buttons. See Changing Key Settings ,
following.
2 Press the desired DSK button(s) on preset. Selected DSK buttons are high-tally.
On preset, the DSK buttons have 3 states: cut, fade, and off. Press the button again to cycle it
to its next state. When the state is ‘cut’, the DSK cuts to the program bus during the next tran-
sition and when the state is ‘fade’, the DSK fades (at its current rate) to the program bus.
3 Optionally, set up other video effects, voice-overs, and transition type and rate.
4 Press the Transition button.
To remove key(s) from program, press the desired DSK button(s) on the preset bus to deselect
them and perform a transition in the normal way. Here too, the DSK buttons have 3 states: cut,
fade, and off. When the state is ‘cut’, the DSK cuts from the program bus during the next transi-
tion and when the state is ‘fade’, the DSK fades from the program bus.
Please note: you can “hot cut” keys directly on and off the program bus at any time , as required,
simply by pressing the desired keyer on the program bus. Hot cuts are not recommended.
Hot cuts have side effects on the preset bus, depending on which transition options are active in
the currently selected Imagestore 750.
