调色 · Color

Power Window(窗口)是调色页里限定调色作用范围的形状遮罩,让调整只作用于画面的某个区域。

  • 内置形状:圆形、矩形、椭圆、线性渐变等,也可以手绘多边形。
  • 可以旋转、缩放、羽化边缘(Softness),让边界自然过渡。
  • 配合跟踪器,窗口可以跟随画面中的运动对象;也可反选,只调整窗口之外的区域。

A Power Window is a shaped mask in the Color page that limits a grade to part of the image.

  • Built-in shapes include circles, rectangles, ellipses, and linear gradients, plus freehand polygons.
  • Windows can be rotated, scaled, and feathered (Softness) so the edge blends naturally.
  • Combined with the Tracker, a window can follow a moving subject; with Outside nodes it can grade everything outside the window instead.
