Adjust mask properties

Last updated on Dec 14, 2023

Before you begin

Create a mask and apply an effect to it.

The editable properties of a mask can vary depending on the type of effect used in the mask. In this example, the Camera Blur effect is used.

Select the mask, and then select Window > Effect Controls panel. In the Effect Controls panel that opens, you'll find mask properties listed under the video clip or effect to which the mask is applied.

To feather the mask: Specify a Mask Feather value. The feathering guide appears around the mask as a dashed line. Drag the handle away from the feathering guide to increase the feathering, or toward the feathering guide to decrease the feathering.
To adjust mask opacity: Specify a Mask Opacity value. The slider controls the mask opacity. At a value of 100, the mask is opaque and blocks out any underlying area of the layer. As you lower the opacity, more of the area under the mask becomes visible.
To expand the mask: Specify a Mask Expansion value. Positive values move the borders outward, and negative values move it inward. You can also drag the handle away from the expansion guide to expand the mask area, or toward the expansion guide to contract the mask area.
To invert the mask: Select the Inverted check box to reverse the masked and unmasked areas. You can protect areas that you want to leave as-is by masking it, and select the Inverted check box to apply effects to the unmasked areas.

The effects are reapplied based on the mask properties you have changed.
