Inserting Characters and Graphics (1) — Title Key

You can insert (or superimpose) text and graphics into the background image while applying effects. You can use either a luminance key or a chroma key for this insertion.

Luminance Key

In a luminance key, a certain luminance level in the foreground image is used as the threshold for creating the key signal, and the corresponding part of the foreground image is inserted into the background image. Normally the foreground image is on a black background, consisting of bright text to be inserted in the background image.

Two-channel luminance keying

With the optional 2nd Channel DME Board installed, you can also use a second luminance key channel.

Note that to select the foreground signal used for the second luminance key, in the delegation section press the FRGD 2 button, turning it on, then select the desired video signal with one of the AUXILIARY buttons.
