Keying setup can be done either by setting directly color references and

tolerances or by using the color grab assistant.

- INVERT BUTTON:

at any time you can choose to invert the

actual keying using this button.

DSK TITLING: after your keying, the DSK titling feature allows you to play with the transparency of your

deleted pixels. Enabling this, simply adjust the opacity settings to make your keyed pixels less or more dark.

This is useful when keying white or light colored text over a bright background.

How to use the LUMA KEY:

Select the lumakiller and then adjust manually, the luma level:

Then adjust the maximum luminance value to define the range of luminance levels which will be deleted.

Once you have completed the setup of your keyed input, place the it in layer B on top of your background

(such as a camera in layer A) in order to complete the keyed title or lower third effect.

How to use the CHROMA KEY:
