7. DVK-300HD Utility User Interface
7.1 Keying Colour Selection and Key Mask Setting
The first step is to select the mode of operation in the Mode section – the Chroma key
button.
The Mode section
Next, the colour to be keyed out should be selected. This setting depends on the keying
background used. There are two possibilities: green or blue. The choice is made by clicking
on Background color in the Chrominance keyer section.
The Background color function
If the colour of the keyed out background is not uniform, the user can make use of the Detect
button, which will calculate the background's RGB parameters using the automated average.
If the parameters cannot be accessed, the user will be notified about it via a message
window, after which the colour will be reset to default. The Default button is used to select
the default colour.
7.2 Show Alpha Matte Function
The next step is preliminary keying setting. This is done with the Show alpha matte function,
which – after a checkbox is checked – will show a matte view for which colours closer to
white are non-transparent and those closer to black are transparent.
