修改器

参考

面板:

侧栏 ‣ 修改器 ‣ 修改器

修改器用于对图像进行调整,如对比度,亮度,饱和度,色彩平衡和应用遮罩。

你可以将这些修改器直接添加到选定的片段上,也可以在 "调整图层" 效果片段中使用它,这允许你将这些修改器同时应用到多个片段上。

使用线性修改器

Calculate modifiers in linear space instead of sequencer space.

复制到选定片段

允许你将修改器复制到选定的片段。这有两种方法来实现,你可以替换旧的修改器或追加/添加到以前的修改器。

通用选项

每个修改器顶部都有几个按钮:

禁用(眼睛图标)

禁用修改器。用于比较图像,非常有用,需要/无需修改图像。

移动(上/下箭头图标)

接下来的两个按钮用于更改堆栈中修改器的位置。

删除 X

交叉是从堆栈中删除修改器。

遮罩

用它来遮罩下面堆栈中的其他修改器。

For example, to correct the brightness only on a certain zone of the image, you can filter the Brightness/Contrast modifier by placing a Mask modifier, just before it in the stack. You can choose to use a Mask created in the Mask editor, or to use another strip as a mask (the image of this strip must have an alpha channel). This mask will be applied on all the others modifiers below it in the stack.

输入遮罩类型

Type of input data used for mask.

片段:

Uses the grayscale representation of the image in a strip to affect the alpha of the current strip.

遮罩:

Use a mask data-block to affect the alpha of the current strip.

遮罩

The Strip or Mask data-block to use as an input.

遮罩时间 仅输入遮罩

How the start frame of the mask is calculated.

相对:

Mask animation is offset to the start of the strip.

绝对:

Mask animation is in sync with scene frame.

类型

目前,支持以下修改器:

亮度/对比度修改器

调整修改器输入的亮度和对比度。

色彩平衡修改器

色彩平衡调整,可通过提升、伽玛和增益或斜率、偏移和功率方法进行调整。

This modifier works similar to the Color Balance Node.

../../../../_images/video-editing_sequencer_sidebar_color-balance-modifier.png

根据所选方法,可以将以下操作应用于SEQUENCER颜色空间中的颜色值:

Lift(提升,暗部调节)/Gamma(伽玛,中间调调节)/Gain(增益,高光调节)
Lift(提升)

提亮暗部颜色值。

伽玛

调节颜色的中间调。

增益

调节高亮区域颜色。

Offset(偏移量)/Power(能量)/Slope(斜率)(ASC-CDL:美国电影摄影师协会-色彩决策列表 的简写)

以下公式分别应用于每个RGB颜色值:: math:c_{out} = (c_{in} * s + o) ^ p

斜率

乘数: math:s 影响除黑色外的所有颜色值。其效果越强,光源颜色越亮。

偏移量

应用斜率后,通过向其添加偏移: math:o 来移动颜色值。请注意, UI中显示的选定值将减去1 ,因此默认值为1意味着实际上没有应用偏移量。

能量(乘方)

总体指数:数学:'p',主要调整中间调。

曲线

颜色和RGB曲线。

This modifier works the same as the Curves Node.

色相校正修改器

HSV多点曲线。

This modifier works the same as the Curves Node.

遮罩修改器

The mask modifier is used to affect the Alpha Channel of the current strip.

For example, to correct the brightness only on a certain zone of the image, you can filter the Brightness/Contrast modifier by placing a Mask modifier, just before it in the stack. You can choose to use a Mask created in the Mask editor, or to use another strip as a mask (the image of this strip must have an alpha channel). This mask will be applied on all the others modifiers below it in the stack.

遮罩时间 仅输入遮罩

相对:

绝对:

色调映射节点

用于将一组颜色映射到另一组颜色,以便在具有更有限的动态范围的媒介中接近高动态范围图像的外观。

This modifier works the same as the Tone Map Node.

白平衡修改器

通过选择白色来用它来调节白平衡。

声音均衡修改器

This modifier can be used to emphasize or suppress sound frequencies. The range is limited to 35Hz - 20kHz and +/-35dB
