Working with the DSK

Use the following steps to perform a downstream key:
1. Ensure that the DSK is properly set up, and the key "type" is selected on the DSK
Input Setup Menu
. In Chapter 6, refer to the "DSK Setup" section on page 296
for instructions.
2. Please remember the following important DSK rules:
~ For ScreenPRO-II destinations, remember that BG B and the DSK are
mutually exclusive.
~ For single or wide screen Encore systems using single M/E Video
Processors, there are only two DVI input connectors available (
1A and
1B). In this configuration, you cannot use both backgrounds and the
DSK — you can only use two of the three.
~ For stack configurations, remember that DSK sources connect to the
“top” stack Processor.
3. In the Layer Control Section, press DSK to display the DSK Adjustment Menu.
4. On the Destination line, select the destination on which you want to perform the
downstream key.
~ If multiple destinations are active, select the desired destination.
~ If a single destination is active, selections cannot be made.
5. On the ID line, select the IDs of the Processor(s) on which you want to perform the
downstream key.
~ For single screen destinations, ID selections cannot be made.
~ For wide screen destinations only, select All to set up all Processors, or
select the
ID of an individual processor.
6. On the Key Type line, select Luma or Color as required.
7. Adjust DSK parameters, including key type, invert, clip, gain, opacity and fill
source. Refer to the "
Modifying Keys" section on page 326 for details.
8. Perform a CUT or AUTO TRANS.
9. Clear the DSK from Program in the normal manner — by clearing its layer from
Preview and then transitioning.
