Sidebar region ‣ Modifiers ‣ Modifiers

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

Calculate modifiers in linear space instead of sequencer space.

Copiar para as faixas selecionadas

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.

Opções comuns

Each modifier has several buttons at its top:

Mute (eye icon)

Disables the modifier. Very useful to compare the image, with / without modifications.

Move (up/down arrow icon)

The next two buttons are used to change the modifier’s position in the stack.

Remove X

The cross is to delete the modifier from the stack.

Masking

Use it for masking the other modifiers in the stack which are below.

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.

Mask Input Type

Type of input data used for mask.

Faixa:

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

Mask:

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

Mask

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:

Mask animation is offset to the start of the strip.

Absoluto:

Mask animation is in sync with scene frame.

Tipos

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:

Realce, gama e ganho

Realce

Aumenta o valor das cores mais escuras

Gama

Adjusts midtones.

Ganho

Ajusta os realces

Deslocamento, potência e inclinação (ASC-CDL)

The following formula is applied to each RGB color value separately: \(c_{out} = (c_{in}*s + o)^p\)

Inclinação

The multiplier \(s\) influences all color values except black. Its effect is stronger the brighter the source color is.

Deslocamento

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.

Potência

Over-all exponent \(p\), which mainly adjusts the midtones.

Curves Modifier

Curvas de cor e RGB.

This modifier works the same as the Curves Node.

Hue Correct Modifier

HSV multi points curves.

This modifier works the same as the Curves Node.

Máscara

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.

Mask Input Type

Faixa:

Mask:

Mask

Mask Time Mask Input Only

How the start frame of the mask is calculated.

Relative:

Mask animation is offset to the start of the strip.

Absoluto:

Mask animation is in sync with 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.
