5 To add softness to the outer range of the key you’re creating, click the plus Softness
control and then click or drag across the portion of the image you’d like to include as a
soft edge.
Once you’ve finished using the range and softness sampling controls to refine the key
you’re using to isolate the subject, nearly every key you pull will benefit from some
further “post-key” refinement. What this means is that, once you’ve created the best
key you can procedurally through sampling the image, you can now adjust the resulting
key itself, which is just a grayscale image, to improve the isolated result. This is what the
Matte Finesse controls are for.
Matte Finesse controls
6 The three most common methods of key refinement using the Matte Finesse controls
are to increase Clean Black to fill in “holes” in the parts of the image you’re omitting
(the background), increase Clean White to close holes in the part of the image you’re
isolating (the foreground), and then use Blur Radius and In/Out Ratio controls to blur the
edge of the key and push it in and out. Using these controls, you can vastly improve
nearly any key without the need to endlessly readjust the Qualifier controls.
More information about using the Matte Finesse controls appears later in this chapter.
7 When you’re finished, click the Highlight control to turn the highlight off, and make
whatever adjustment you need. In this example, the saturation has been raised and the
color balance changed to make the adjustment obvious.

If you have a DaVinci control panel, you can use the fourth trackball to sample the image,
referring to either the Viewer or the display connected to the video output of your
DaVinciworkstation.
