When the Preview screen shows the desired chroma key results:
¨ Press PLAY . The Output monitor shows the Chroma Keyed image. Press PLAY
again to cut back to the background source.
You can also dissolve between the Background footage and the Chroma Key foot-
age using the T-BAR , rather than pressing PLAY .
You can apply Input Effects (including Freeze) to the Background footage, but not to the
Keyed footage.
¨ To apply the freeze effect, press FREEZE either before or after pressing CHROMA
KEY or SHIFT+CHROMA KEY .
¨ To apply any of the other Input Effects, apply them to the CURRENT source before
pressing CHROMA KEY . MXPro ignores effects applied to the NEXT source during
Chroma Key.
You can fine-tune the chroma key effect so that more or less of the keyed footage gets
keyed. You can separately adjust the range of colors and video brightness that get
keyed.
• To adjust the brightness range, enter SHIFT+UP ARROW to increase the range of
brightness values that get keyed, replacing more of the keyed footage with the
background footage. Use SHIFT+DOWN ARROW to decrease the brightness
range, reducing the portion of the image that gets keyed.
• To adjust the color range , enter SHIFT+RIGHT ARROW to increase the range of
colors that get keyed, replacing more of the keyed footage. Use SHIFT+LEFT
ARROW to decrease the range of key-colors, reducing the portion of the image
that gets keyed.
When you finish using chroma key, press CHROMA KEY .
