介绍

遮罩可以在"图像"和"视频片段"编辑器中创建，使用方法为将标题中的模式更改为“遮罩”。这将向编辑器面板添加各种工具和属性，同时隐藏与遮罩交互不需要的其他工具和属性。

Masks have many purposes. They can be used in a motion tracking workflow to mask out, or influence a particular object in the footage. They can be used for manual rotoscoping to pull a particular object out of the footage, or as a rough matte for green-screen keying. Masks are independent from a particular image of movie clip, and so they can just as well be used for creating motion graphics or other effects in the Compositor.

在合成器使用遮罩节点孤立(就是将需要的元素扣像)目标。

虽然 “视频剪辑编辑器” 和“图像编辑器” 用于编辑遮罩，但“合成器”和"图像序列”仅使用已创建的遮罩。

Masks can be animated over the time so that they follow some object from the footage, e.g. a running actor. This can be achieved with shape keys or parenting the mask to tracking markers.

遮罩数据块类型

遮罩数据块类型包含多个遮罩层和样条线。它们是用于掩蔽目标的最高级控制级。遮罩可以在不同的地方重用，并为它们所包含的所有实体保存全局参数。
