Applying a mask to your Matrox effects

The Matrox color correction, chroma key, and luma key effects allow you to add
a mask to define the area where you want to apply your effect. For example, you
may want to apply a color correction to only one area of your clip and leave the
rest of the clip untouched.

Click the triangle next to Mask to expand the property list.
The properties under Mask let you control the area on the clip where you want to
apply the mask. You can enter the values you want in the text boxes or drag the
appropriate sliders ( Left , Right , Top , and Bottom ).
• Left Adjusts the left edge of your mask.
• Right Adjusts the right edge of your mask .
• Top Adjusts the top edge of your mask.
