To use Keying, first select a source in the desired layer:

Layer button -> source number button

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.

Keying/Titling menu -> Type menu -> Select your keying type

Once your keying mode is selected, the

Eikos LE 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 medium intensity.

The black and white levels define where to begin the keying. In the range 0 to 255, 0 repre-

sents no luminance, or black and 255 represents full luminance, or white.

Level Black:

As the Black Level is changed from 0 to 255, things that are black are first

keyed out, followed by dark grey, then light grey, and so forth, until the entire picture is keyed

out at 255.

Level White:

As the White Level is changed from 255 to 0, things that are white are first

keyed out, followed by light grey, then dark grey, and so forth, until the entire picture is keyed

out at 0.
