Working with DSK (Chroma / Luma key)
DSK Mode must be used with remote controllers specifically designed to control the SMX200.
- SMX200 allows to use a live source with green or blue (or any color) background and to key it over another live
input.
- Background is removed and replaced by another source.
- Title can be keyed (DSK) on Analog or Digital Sources.
To use Keying, first select a source in the desired layer:
Then in the main menu, select the Keying/Titling menu.
You now have several choices to key your sources. The Luma Key and the Chroma Key based on the Luma
pixel values and the Chroma pixel values and for both an additional Titling menu which can be useful to
choose the transparency value of your keying.
Once your keying mode is selected, the Smart MatriX provides you some keying advance setting:
For Luma Key:
Luma Keying is used to key from a particular luminous intensity. It produces a hard edged key based
on intensity, which is most suitable for titling effects. You can choose to key things that are extremely
dark or extremely bright and keep everything in between, or invert to key only things that are of a me-
dium intensity.
The black and white levels define where to begin the keying. In the range 0 to 255, 0 represents no
luminance, or black and 255 represents full luminance, or white.
- Level Black:
followed by dark grey, then light grey, and so forth, until the entire picture is keyed out at 255.
- Level White:
followed by light grey, then dark grey, and so forth, until the entire picture is keyed out at 0.
