动态关键帧Dynamic Keyframes
学习目标LEARNING OBJECTIVES
学完你能分清静态关键帧（Static）与动态关键帧（Dynamic），并用动态关键帧让调色跟着镜头里的光线变化平滑过渡。
概念说明CONCEPTS
动态关键帧（Dynamic Keyframes）记录两个时间点的调色状态，让参数在它们之间平滑插值——镜头中途光线变了，调色跟着变，观众看不到接缝。
- 静态跳、动态变：静态关键帧（Static）到点瞬间切换，适合硬切式变化；动态关键帧在两帧之间渐变，适合连续变化。
- 关键帧打在节点上：调色页的关键帧以 Corrector 节点为单位，记录该节点全部参数的快照，两点之间一起过渡。
- 面板分左右：
Keyframe面板左侧是关键帧时间线，负责打点和挪点；右侧 Keyframe Editor 显示数值曲线。 - 典型场景：从室内走到室外、日落渐暗、灯光突然打开——凡是"一条镜头里光线变了"的地方。
操作步骤STEPS
- 在调色页面选中镜头和目标节点，点面板切换栏的
Keyframe打开关键帧面板 - 把播放头移到变化起点，点该节点轨道右端的菱形
Mark按钮，打下第一个关键帧
- 把播放头移到变化终点，再点一次
Mark，打下第二个关键帧 - 直接拖动色轮，把画面调成终点想要的样子——改动自动记录在这个关键帧上
- 播放检查：两个关键帧之间所有参数平滑过渡；想改节奏就左右拖动菱形标记
- 需要瞬间跳变时，选中关键帧，把类型从
Dynamic改为Static
练习PRACTICE
- 找一段光线渐变的素材，用两个动态关键帧让曝光平滑跟上光线，播放变化段确认无跳变。
- 把同一组关键帧在
Dynamic与Static之间切换，各播一遍，写下两种过渡的观感差别。
常见问题FAQ
参数的变化曲线在哪里看？
Keyframe 面板右侧的 Keyframe Editor。选中关键帧就能看到数值曲线——曲线越陡，变化越快。
调色变了，但变化的时机不对怎么办？
挪点就行。在关键帧时间线上直接拖动菱形标记，只改"什么时候到位"，不改数值本身。
关键帧打错了怎么删？
在时间线上选中那个菱形标记，按 Delete 删除；删点不影响你在其他关键帧上存好的调色状态。
想让画面里某个窗口跟着人走，也用这个吗？
不是。那是运动跟踪的活——用跟踪器分析路径再贴给窗口，见 运动跟踪。关键帧管"参数随时间变"，跟踪管"选区随物体动"。

After this card you can tell static keyframes from dynamic keyframes, and use dynamic keyframes to make a grade follow the light changes inside a shot with smooth transitions.
Concepts概念说明
Dynamic keyframes record the grade at two points in time and interpolate every parameter smoothly between them — when the light changes mid-shot, the grade follows, and the audience never sees a seam.
- Static jumps, dynamic flows: a Static keyframe switches values the instant it arrives — good for hard changes; a dynamic keyframe ramps between two points — good for continuous change.
- Keyframes live on nodes: Color page keyframing works per Corrector node, storing a snapshot of all its parameters, and everything transitions together.
- The palette has two halves: on the left of the
Keyframepalette, the keyframe timeline places and moves points; on the right, the Keyframe Editor shows the value curves. - Typical scenes: walking from indoors to outdoors, a fading sunset, a lamp switching on — anywhere the light changes within one shot.
Steps操作步骤
- On the Color page, select the shot and the target node, then click
Keyframein the palette switcher to open the keyframe palette - Move the playhead to where the change should start and click the diamond
Markbutton at the right end of the node's track to place the first keyframe - Move the playhead to where the change should finish and click
Markagain for the second keyframe - Drag the wheels until the image looks the way it should at the end — the change is recorded on this keyframe automatically
- Play it back: every parameter eases between the two keyframes; to retime the change, drag the diamond marks left or right
- Need an instant switch instead? Select the keyframe and change its type from
DynamictoStatic
Practice练习
- Take a clip where the light shifts gradually, follow it with two dynamic keyframes so exposure tracks the light, and play the changing section to confirm there is no jump.
- Switch the same keyframe set between
DynamicandStatic, play both, and write down how the two transitions feel different.
FAQ常见问题
Where do I see the value curves?
In the Keyframe Editor on the right of the Keyframe palette. Select a keyframe to see its curve — the steeper the curve, the faster the change.
The grade changes, but the timing is wrong?
Just move the point. Drag the diamond mark along the keyframe timeline — that changes when the value arrives, not the value itself.
How do I delete a misplaced keyframe?
Select the diamond mark on the timeline and press Delete. Removing a point doesn't affect the grade stored on your other keyframes.
I want a window to follow a person — is this the tool?
No. That's motion tracking — analyze the path with the tracker and attach the window to it, see Motion Tracking. Keyframes change parameters over time; tracking moves a selection with an object.
