Use the “Mask Feather” property to adjust the softness of the mask edges. Press “F” to reveal the Feather property and keyframe it to control the feathering over time.5. Animating Mask Shape: To change the shape of a mask over time, add keyframes to the mask path property.6. Mask Opacity: Along with position, scale, and shape, you can also animate the opacity of a mask to gradually reveal or hide elements. Press “T” to reveal the “Opacity” property, create keyframes, and adjust the value as needed.7. Mask Expansion: If you wish to animate the expansion or contraction of a mask, use the “Mask Expansion” property. Press “M” twice to reveal the Mask Expansion property and keyframe the value to control its size over time.8. Easy Ease: To add a more organic and smooth motion to your mask animations, apply the “Easy Ease” keyframe assistant.
