The 3D parameters include:
Show Paths: A checkbox that lets you turn the visibility of the lines you’re drawing to
sample the image on and off. Turning lines off does not affect the key in any way.
Colorspace: A drop-down menu that lets you choose whether you’re sampling colors in
YUV colorspace or HSL colorspace. YUV is the default, but if you find you’re not getting
satisfactory results, you can reset the Qualifier palette and switch to HSL to see if that
works any better.
Softness: A single parameter lets you adjust the overall softness of the key you’re
creating. The default value is 50. Raising this value increases key softness, lowering it
decreases key softness.
Despill: If you’re using the 3D keyer to pull a blue or green screen key to create
transparency in conjunction with the optional Alpha output in the Node Editor, this
checkbox lets you turn on an automatic color correction that eliminates blue or green
spill from the image, while retaining the image’s original color.
Sample list: A list shows each line you drew as a sampled entry. A color patch at
the left shows you the average color you sampled, clicking the color patch lets you
temporarily turn any color sample off to evaluate its contribution to the overall key. A
plus or minus icon shows you whether that patch is adding to or subtracting from the
key. The average red, green, and blue color values are shown next, and a trash can
icon at the right lets you delete any sample from the list.
Matte Finesse Controls
After you’ve used the sample controls and qualifier parameters to create the most useful key for
your purposes, you may find that it has problems that cannot be overcome easily by the
available adjustments. Issues such as chattery edges, holes, or noisy bits can sometimes be
easily fixed using the Matte Finesse controls. These controls filter the output of the Qualifier
controls and are adjustments that are made to the matte itself, so they may work well in some
instances, and poorly in others, depending on what you’re trying to do.

Denoise has been re-added to the Matte Finesse controls, providing a distinct way to post-
process extracted keys to selectively reduce the noise in a key, getting rid of stray areas of
qualification and softly filling “holes” in a matte.
