PERFORMING THE CHROMA KEY

When the preview screen shows the desired chroma key results:

•Press PLAY. The output monitor shows the chroma key image. Press PLAY again to cut back to the background source.

You can also dissolve between the background footage and the chroma key footage using the T-BAR, rather than pressing PLAY.

Using Freeze and

Other Input

Effects

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 CHROMAKEY or

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.

Ending Chroma Key

When you finish using chroma key, press CHROMAKEY.
