Creating a 4-corner pin effect
The Matrox 4-corner pin effect lets you anchor each corner of a video or graphics
clip onto points in an underlying clip, even if the underlying clip is angled or
skewed. You could use this effect, for example, to overlay a video clip onto an
underlying clip of a television screen.

Edge Softness
Lets you apply softness to the edges of your clip. If your
clip is skewed, you may get more desirable results using the
Skewed Edge
Softness
control.
•
Skewed Edge Softness
If you altered your clip so that the perspective is
skewed, you should use this option to apply softness to the edges of your
clip.
¡ Important
Skewed Edge Softness
is not supported on clips where any
corner is positioned beyond the boundaries of another corner. In order for the
Skewed Edge Softness
to work correctly, your clip should be a flat plane
with four visible corners.
