What are two tools for making masks in After Effects?

The Pen tool and shape tool are the primary tools used for creating masks in After Effects. The Pen tool is particularly useful for drawing custom paths and shapes, allowing for precise control over the mask's outline. This enables users to create intricate and detailed masks that can follow the contours of an object or shape in a video or composition.

The shape tool, on the other hand, provides a quick way to create basic geometric masks (like rectangles, ellipses, and polygons) that can be used to hide or reveal portions of layers. Both tools contribute significantly to the flexibility and creativity of masking in After Effects, making it easier to isolate subjects, create complex visual effects, or apply adjustments to specific areas of a layer.

The other options involve tools that serve different purposes in After Effects. The brush tool and eraser tool are primarily used for painting or erasing on layers rather than for masking. The selection tool and transform tool manipulate layers but do not create masks. The clone tool and paint tool are used for duplicating and painting effects directly on layers. Thus, the Pen tool and shape tool stand out as the most relevant for mask creation.
