6. Press the Auto Setup button in the Keyers – Chroma Key menu. Preview
for that M/E will now display the chroma key source with a
superimposed cross hair cursor. The cursor actually represents a box of
16 x 16 pixels.
7. Use the joystick to position the cursor on the backing color. Select a
darker area, if one exists, to optimize the backing color suppression.
8. Press the button on top of the joystick. The chroma key will be set up
automatically using the average of the colors selected by the cursor box.
Because
Reshape was off, fine edges of the key will be preserved.
