先学：Prerequisites: 二级调色

学习目标LEARNING OBJECTIVES

学完你能说清窗口（Power Window）是什么、有哪些形状，并会用窗口把调色限制在画面的指定区域里。

概念说明CONCEPTS

窗口（Power Window）是用形状圈定画面区域的遮罩工具——二级调色中最常用的隔离手段：调整只落在形状罩住的区域，区域外的画面分毫不动。

  • 形状家族齐全：线性（Linear）、圆形（Circular）、多边形（Polygon）、钢笔曲线（Curve），从规则几何到徒手勾勒都能画。
  • 窗口属于节点：画在哪个节点就只限制哪个节点；局部调整请开新节点再画窗，别碰已完成的一级调色（见 节点工作流）。
  • 软边决定真假：Soft 参数给遮罩边缘加羽化——让人看不出"这里被圈过"，才是合格的窗口。
  • 会动就要跟踪：窗口不会自己追物体；主体移动时靠跟踪器让窗口跟随（见 跟踪器）。

操作步骤STEPS

  1. 进入 Color 页面，新建串行节点（Option-S/Alt-S）并命名，如 SKY
  2. 在中部面板工具栏点 Window 图标，点选一个形状（如圆形 Circular）Window 面板与形状按钮
  3. 在检视器中拖窗口中心移动位置，拖白色控制点缩放，拖中心手柄旋转
  4. 在该节点上直接调色——效果只落在窗口罩住的区域窗口内的局部调整
  5. 在 Window 面板右侧拉大 Soft 数值，把遮罩边缘羽化到自然
  6. 点检视器左下角 Overlay 选 Off 隐藏轮廓线，按 Command-D/Ctrl-D 对比调整前后

练习PRACTICE

  1. 用圆形窗口圈住画面主体并轻微提亮，再把 Soft 从 0 拉大到看不出边缘。
  2. 换一个镜头，用 Curve 钢笔沿天空轮廓画一个任意形状，给天空单独加暖。

常见问题FAQ

画了窗口再调色，怎么没效果？

先确认窗口画在当前节点上（橙色描边）；再注意调整只发生在形状内部——窗口外的区域是看不到变化的。

窗口边缘太硬，一眼看出被圈过？

拉大 Soft 羽化，并切全屏（Command-F/Ctrl-F）复查。自然的窗口应该让人察觉不到边界。

轮廓线挡住画面，看不清效果？

点检视器左下角 Overlay 选 Off 隐藏；想再看轮廓时选回 Power Window 即可。

主体在动，窗口跟不上怎么办？

用跟踪器让窗口自动跟随运动（见 跟踪器）；逐帧手拖位置只是最后手段。

Learning Objectives学习目标

After this card you can explain what a Power Window is, name its shape types, and use a window to confine a grade to a chosen area of the frame.

Concepts概念说明

A Power Window is a shape-based mask that marks off an area of the frame — the most-used isolation tool in secondary grading: your adjustment lands only inside the shape, and everything outside stays untouched.

  • A full shape family: Linear, Circular, Polygon and the Curve pen — from regular geometry to freehand outlines.
  • Windows belong to a node: a window limits only the node it was drawn on. Open a new node for local work; never touch the node holding your finished primary grade (see Node Workflow).
  • Softness sells the trick: the Soft parameter feathers the mask edge — a good window is one nobody can spot.
  • Motion needs tracking: windows don't follow subjects by themselves; use the tracker to attach them (see Tracker).

Steps操作步骤

  1. On the Color page, add a serial node (Option-S/Alt-S) and label it, e.g. SKY
  2. Click the Window icon in the center palette toolbar and pick a shape (e.g. Circular)The Window palette and shape buttons
  3. In the viewer, drag the window's center to move it, the white control points to resize, and the center handle to rotate
  4. Grade directly on this node — the effect lands only inside the windowA local adjustment inside the window
  5. Drag the Soft value up on the right of the Window palette until the edge looks natural
  6. Click Overlay in the viewer's lower-left corner and choose Off, then press Command-D/Ctrl-D to compare before and after

Practice练习

  1. Circle the subject with a Circular window and brighten it slightly, then raise Soft from zero until the edge disappears.
  2. On another shot, draw a freeform shape along the sky with the Curve pen and warm up the sky alone.

FAQ常见问题

I drew a window but my grading does nothing?

Check the window is on the active node (orange outline), and remember the adjustment only happens inside the shape — nothing changes outside it.

The window edge is so hard it's obvious?

Raise Soft to feather it, then check full screen (Command-F/Ctrl-F). A natural window has an edge no one notices.

The outline blocks my view of the image?

Click Overlay in the viewer's lower-left corner and choose Off; choose Power Window to bring the outline back.

The subject moves and the window can't keep up?

Use the tracker to make the window follow the motion (see Tracker); dragging it frame by frame is a last resort.
