Applying a Chroma Key Effect
You can use the options in the Foreground category of 3D Warp to apply a chroma key effect. You
also have the option of using the SpectraMatte option for a chroma key that has higher quality and
gives you greater control over the final look of the effect. For more information, see “Key:
SpectraMatte Effect” on page 463.
To apply a Chroma Key effect:
1. Edit the foreground image onto track V2 and the background image onto track V1 in the
Timeline.
For information about editing a sequence, see “Creating and Editing Sequences” in the Help.
2. Apply the 3D Warp effect to track V2.
For more information, see “Applying the 3D Warp Effect” on page 283.

6. (Option) If Media Composer includes the 3D Spill Suppression parameter category, use Spill
Suppression if necessary to remove spill in the foreground image.
7. (Option) Use the sliders in the Foregnd parameter category to make refining adjustments to
improve the look of the key.
