Modifiers(モディファイアー)#
参照
- Panel(パネル):
Modifiers are used to make adjustments on the image, like contrast, brightness, saturation, color balance and applying masks.
You can add these modifiers directly to the selected strip, or you can use it within an "Adjustment Layer" effect strip, which allows you to apply these modifiers onto several strips the same time.
- Use Linear Modifiers
Calculates modifiers in linear color space instead of the Sequencer color space.
Calculating modifiers in linear space will match the image processing of the compositor. In most cases this should be enabled, working in a non-linear workflow could have unpredictable results.
- Copy to Selected Strips
Allows you to copy the modifiers to selected strips. This works two ways, you can either replace the old modifiers or append/add to the previous modifiers.
共通のオプション#
Each modifier has several buttons at its top:
- Mute (eye icon)
Disables the modifier, useful to compare the image, with or without modifications.
- Move(移動) (上/下矢印アイコン)
These two buttons change the modifier's position in the stack which affects their computation order.
- Remove(削除)
X Deletes the modifier from the stack.
Masking#
Each Modifier has an option to mask the effect of the modifier and any modifiers below it. For example, to correct the brightness only on a certain zone of the image, you can filter the Brightness/Contrast modifier.
The mask can either be a Mask created in the Mask editor or use another strip as a mask.
- Mask Input Type
Type of input data used for the mask.
- Strip(ストリップ):
Uses the grayscale representation of the image in a strip to mask the affects of the modifier.
- Mask(マスク):
Use a mask data-block to mask the affects of the modifier.
- Mask(マスク)
The Strip or Mask data-block to use as an input.
- Mask Time Mask Input Only
How the start frame of the mask is calculated.
- Relative(相対):
Mask animation is offset to the start of the strip.
- Absolute(絶対):
Mask animation is in sync with the scene frame.
タイプ#
Currently, the following modifiers are supported:
Brightness/Contrast Modifier#
Adjusts the brightness and contrast of the modifier input.
Color Balance Modifier#
Color balance adjustments, either by the Lift, Gamma, and Gain or the Slope, Offset and Power method.
This modifier works similar to the Color Balance Node.
Depending on the selected method, the following operations can be applied to the color values in the sequencer color space:
- Lift/Gamma/Gain(リフト/ガンマ/ゲイン)
- Lift(リフト)
暗い色の値を上げます。
- Gamma(ガンマ)
中間色を調整します。
- Gain(ゲイン)
ハイライトを調整します。
- Offset/Power/Slope (ASC-CDL)(オフセット/パワー/スロープ(ASC-CDL))
The following formula is applied to each RGB color value separately: \(c_{out} = (c_{in}×s + o)^p\)
- Slope(スロープ)
The multiplier \(s\) influences all color values except black. Its effect is stronger the brighter the source color is.
- Offset(オフセット)
Shifts color values after applying Slope by adding the Offset \(o\) to them. Note that the selected value shown in the UI will be subtracted by 1, so the default value of 1 means effectively no offset is applied.
- Power(パワー)
Over-all exponent \(p\), which mainly adjusts the midtones.
Curves Modifier#
Color and RGB curves.
This modifier works the same as the RGB Curves(RGBカーブ)ノード.
Hue Correct Modifier#
HSV multi points curves.
This modifier works the same as the Hue Correct(色相補正)ノード.
Mask(マスク)モディファイアー#
The mask modifier is used to affect the Alpha Channel of the current strip.
- Mask Input Type
Type of input data used for the mask.
- Strip(ストリップ):
Uses the grayscale representation of the image in a strip to affect the alpha of the current strip.
- Mask(マスク):
Use a mask data-block to affect the alpha of the current strip.
- Mask(マスク)
The Strip or Mask data-block to use as an input.
- Mask Time Mask Input Only
How the start frame of the mask is calculated.
- Relative(相対):
Mask animation is offset to the start of the strip.
- Absolute(絶対):
Mask animation is in sync with the scene frame.
Tone Map Modifier#
Used to map one set of colors to another in order to approximate the appearance of high dynamic range images in a medium that has a more limited dynamic range.
This modifier works the same as the Tone Map Node.
White Balance Modifier#
Use it to adjust the white balance by choosing the color that should be white.
Sound Equalizer Modifier#
This modifier can be used to emphasize or suppress sound frequencies. The range is limited to 35Hz - 20kHz and +/-35dB
