You can apply Input Effects (including Freeze) to the background footage, but not to the keyed

SHIFT + CHROMAKEY .
• To apply any of the other Input Effects, apply them to the CURRENT source before pressing
CHROMAKEY . The MX-4 DV ignores effects applied to the NEXT source during chromakey.
Fine-Tuning Key Colors
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 gets keyed.
•
To adjust the brightness range, enter SHIFT + UP ARROW to increase the range of brightness val-
ues 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.
