Adjust the Primatte RT parameters:
1 In the Primatte RT Dashboard, or the Inspector > Filters tab, choose Matte from the
Output Type pop-up menu.
The matte is displayed in the Canvas. When the Primatte RT filter is first applied to the
image, it automatically starts to pull the key. However, often the matte is not clean—
there are many gray areas. Any dark areas of the matte result in transparency in the
areas that should be opaque.
2 Clean up the matte in the Primatte RT parameters:
a In the Auto Sample parameter, click Blue. If using a green screen shot, click Green.
When the Primatte RT filter is first applied to an image, the image is auto-sampled
and the best estimated keying color is inferred. By clicking Auto Sample, the
dominant color in the image (between red, green, and blue) is automatically sampled
and used as the keying color.
