Transition Controls Panel; Key 1 And Key 2 - Datavideo SE-1200MU Quick Start Manual

Transition Controls Panel

Key 1 and Key 2

Each KEY button has an LED above it. This LED can be Red or Green. The KEY button itself can be Off or On (back
lit Green when On). To understand the relationship between the KEY button and the LED above, try the
following example with Key1 already set up as described under the previous Keying sections
selection transition).
1. If the KEY1 button is Off and the LED above it is Red then KEY1 is not active in Program or Preview.
2. If the KEY1 button is On and the LED above it is Red then KEY1 is currently active in Preview Only.
3. If a CUT, MIX, WIPE transition is performed with the T-Bar or AUTO TRANS button then KEY1 will move to
the Program output. Once the transition is complete, the LED above KEY1 will change from Red to Green
to confirm the key is currently active on the Program output.
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.
Once Key1 and Key2 are properly set up, they can both be used separately within the same production or placed
over one another so they are both displayed within the Preview / Program output.
Before using the two keys at the same time in a live production, some preparations are required. The best way is
to keep the keys simple. The user should decide which key should be on top and practice the effect that you
want to create a few days before the live event.
The SE-1200 MU has several buttons for deciding the on-screen order of the Key1/Key2 as well as deciding how the
key will enter or exit, from the production. In the following example, we will be using buttons on the Transition
Controls and Transitions panels whilst looking at the Preview and Program monitors.
