4K 2K-DPM Quad Offset Borders and Cropping
4K 2K-DPM Quad Offset Borders and Cropping
When a 4K 2D DPM is created using four 2D DPMs, the inner borders are disabled. When a
Quadrant Offset is enabled for one 1080p 2D DPM, the inner borders are enabled.
Crops are calculated so that when you crop from the top or sides of a 4K keyer using
Quadrant Offsets, the entire image is cropped simultaneously. This means, if for example
only the keyers for Quadrant 3 and 4 are on, the crop will not be visible until it reaches the
top edge of Quadrants 1 and 2 in the target space.
Create a 4K 2D DPM Effect in 4K SDQS Mode
In 4K SDQS mode, a 4K 2D DPM is configured using keyers from two logical M/Es. Each 4K
M/E has the first three keyers available (Key 1-Key 3) for K-Frame Standard and Compact
and GV K-Frame X and two for S-series and V-series. 4K DPMs require a 4K source, see the
Kayenne/Karrera/GV Korona Installation & Service Manual for information about configuring
4K sources.
The following example describes how to use bus linking so the same source will be selected
on four keyers from two M/Es and enable a 4K 2D DPM that uses Control Panel reentry to
delegate the 2D DPM to a single keyer button on PGM.
Prerequisite: 4K sources are mapped to the Control Panel (2D DPM configuration can also
be completed using just the switcher menu).
1 Create a bus link so each key will select the same source simultaneously (example):
a In the Source Ops, Bus Links, Links Setup tab, select the Controlling Bus data pad.
b Select a Controlling Bus in the ME Buses tab (ME2, Key1).
c Select the Controlling Bus (Controller) in the Current Link pane, left.
d Select the Linked Bus data pad and select a linked bus (ME 2, Key 2).
e Repeat for the next two links (ME 3, Key 1 and ME 3, Key 2).
f Verify all current links are enabled and the Link Enable button is on.
2 Select a 4K key source on the Control Panel.
3 In the iDPM, Transform, Keyers 2DPM menu tab, select the ME and keyer to be used as a
quarter of the 4K image.
4 Select the Quadrant button in the Clears & Enables pane, top right of the menu and
select an Offset button to move the quarter image to the desired location;
• 1 Offset , top left
• 2 Offset , top right
• 3 Offset , bottom left
• 4 Offset , bottom right.
5 Enable and select quadrants for the other three 2D DPMs, making sure the correct
images for each of the four quadrants are on-screen.
Result: With all four keyers cut on, a full 4K key is visible on-screen.
6 Chain the 2D DPM enabled keyers so they will go on and off air simultaneously:
a In the User Setups, Suite Prefs, Transition Key Chaining menu, with the Key Chains
button selected (bottom left), select a Key Chaining data pad (turns light blue).
