Priority Button; Previewing A Selected Transition; Rev And Norm / Rev Buttons - Datavideo SE-3000 Instruction Manual

4. If the T-Bar or AUTO TRANS button is used again then the KEY1 button will remain On but the LED
above will change back from Green to Red. KEY1 is now removed from the Program output and is
active only in the Preview output.
5. To remove KEY1 from the Preview output press the KEY1 button so it is Off and not back lit Green.
The LED above KEY1 should be Red also. This confirms KEY1 is not active in Program or Preview
and we are now back at point 1.
The Key2 button and the LED above it perform in exactly the same way as described for Key1.

Priority Button

When Key1 and Key2 are both active in Preview (or Program) they may overlap each other on screen.
Using the Priority Button you can change the order of these keyers. The button acts in a toggle on/off way.
So Key1 over Key2 or Key2 over Key1.
NOTE: It is best to check and change the Priority of Key1 and Key2 when they are only active on the
Preview monitor/output.

Previewing a selected transition

It is possible to see or test the effect of a chosen MIX, WIPE or DVE transition in the Preview Monitor before
using it on the Program output.
In order to do this look at the Transition Controls group of buttons on the Control Panel and below the
BGND (Background) button is the TRANS PVW button. Once the TRANS PVW button is ON and backlit
Green, select and use the transition that you want to test on the Preview monitor. You will also notice that the
Preview Monitor switches to the currently selected Program source when the TRANS PVW button is turned
on. Do not worry, the chosen Preset source has not changed. Press the AUTO TRANS button or move the
T-Bar manually to preview the chosen transition.
NOTE: Remember to turn off the TRANS PVW button before attempting to use the chosen transition on
the Program output.

REV and NORM / REV buttons

When the REV and NORM / REV buttons are OFF the selected WIPE or DVE transition will operate in its
default direction only.
When the REV button is ON then the selected transition will operate in the reverse direction only.
When the NORM / REV button is ON the selected WIPE or DVE transition will automatically switch directions
as each transition is completed. The REV button will switch on and off automatically to indicate the direction
of the next transition.
