Mask Dilation

โ€ŒMask Dilation

Use the Mask Dilation field to expand the edges of the mask by a specified number of pixels. This helps prevent auto trackers from picking up unwanted edge details (e.g., blurry hair or soft fringes), especially in lower-sharpness footage. The dilation is applied when the mask is written, allowing you to control how much the mask grows to better exclude problematic regions from tracking.
