Managing and animating shape paths and masks

You animate mask paths and shape paths in much the same way that you animate other properties: set keyframes for the Mask Path or Path property, set paths at each keyframe, and After Effects will interpolate between these specified values.

• Rotoscoping introduction and resources

• Select shape paths, shapes, and shape groups
• Select masks, segments, and vertices

• Convert a path between manual Bezier and RotoBezier
• Modify a Bezier mask path or shape path
• Change a mask path numerically
• Designate the first vertex for a Bezier path
• Animate a mask path with Smart Mask Interpolation
