Chapter 6, Setting Up Realtime Effects with Adobe Premiere
• Map This view consists of a cube that contains a color spectrum, located
under
Chroma Map, and a luminance spectrum located under Luma Map.
When you adjust the keyer controls, you can see the visual representation of
your changes in the
Chroma Map or Luma Map:
•
Matte This view displays the matte used to create your key effect. In the
following example, you can see a white silhouette against black, with
semi-transparent areas, such as soft edges, seen as grays. As explained for
the
Output view, you can use the tracking rectangle in the Matte Window
to select an area containing the colors on which you want to key.
¥Tip You can switch to the Matte view to further refine your key color. For
example, in
Matte view, your key color (such as green) appears as black,
and opaque areas appear as white. If you notice some white spots that you
want to key, hold down the
CTRL key as you draw the tracking rectangle
over the white dots to add them to your key color. You can also adjust the
keyer controls until the undesired white spots disappear.
