Keying Mode
Keying is an extension of the PIP function and is realized by reducing the designated color
from the image color input by the PIP channel. The image matting function can be applied to
some simple special effect processing and caption adding.
Caption Add
PIP Channel + Main Picture Channel = Caption Effect
Parameter Settings
Select "function" in the main menu
→
Choose "on" in the "PIP settings" menu and
"keying" in the "mode". And choose black for "color key" in the "settings" menu.
As seen in the Fig. 10.4, the image of white characters on black background is input to the
PIP channel; when the two pictures are overlapped, we can get the caption effect by removing
the black.
