7.1.2 Keyer Matte
1. The Colour Palette allows selection of a colour for the Keyer Matte .
2. Click on the Colour Palette and the crosshair will move to display the currently selected colour where
the mouse pointer was located. The selected colour RGB values will also be shown to the right.
3. The Luma value determines how bright or dark the selected colour or hue is. The Luma can be
adjusted by clicking on the Luma value and using the pop up keypad to enter the new value.
4. The
Sat
or
Saturation value
moves the crosshair from the center of the colour palette to the outer
edge. The Sat value can be adjusted by clicking on the Sat value and using the pop up keypad . If the
Hue angle is set to 180 degrees then the Sat value determines how much Cyan is in the matte.
5. The
Hue parameter
moves the crosshair around the colour palette in the clockwise or anti-clockwise
direction. The Hue value or angle can be adjusted by clicking on the Hue value and using the pop up
keypad .
Certain colour hues can be found at certain angles on the colour palette. For example, Red is 0
degrees (12 o’clock position), Green is approximately 120 degrees (4 o’clock position) and Blue is
approximately 240 degrees (8 o’clock position).
For Luma key purposes using zero values for Luma, Sat and Hue will allow a black keyer matte to be
chosen as above.
A white keyer matte can be created from Luma 100%, Sat zero and Hue zero.
7.2 Linear key - Quick DSK 2 Setup
Note: The DSK 1 and DSK 2 keyers can only be used for Linear or Luma keying . Chroma keying is not
supported on DSK 1 and DSK 2.
In this downstream keying example, we are supplying the SE-1200 MU with a live video signal on input 2,
this is selected on the Program and Preview rows. We have also connected a CG-350 Character Generator
(separate purchase) which is supplying separate KEY and FILL signals to inputs 5 and 6. These two CG-350
inputs will be used for Linear keying the CG- text and graphics over the live video from input 2.
