The Video Limiter effect lets you limit the luminance and color in a clip so that they fall within parameters that you define. These parameters are useful for preserving the video as much as possible while making its signal fall within the broadcasting limits.

Show Split View

Displays one part of the image as the corrected view and the other part of the image as the uncorrected view.

Layout

Determines whether the Split View images are side by side (Horizontal) or above and below (Vertical).

Split View Percentage

Adjusts the size of the corrected view. The default is 50%.

Reduction Axis

Lets you set the limits defining the range of luminance (Luma), color (Chroma), both color and luminance (Chroma and Luma), or the overall video signal (Smart Limit). The Min and Max controls available depend on the Reduction Axis option you choose.

Luma Min

Specifies the darkest level in an image.

Luma Max

Specifies the brightest level in an image.

Chroma Min

Specifies the lowest saturation for the colors in an image.

Chroma Max

Specifies the maximum saturation for the colors in an image.

Signal Min

Specifies the minimum video signal including both brightness and saturation.

Signal Max

Specifies the maximum video signal including both brightness and saturation.

Reduction Method

Lets you compress specific tonal ranges to preserve detail in important tonal ranges (Highlights Compression, Midtones Compression, Shadows Compression, or Highlights and Shadows Compression) or compress all tonal ranges (Compress All). Compress All is the default.

Tonal Range Definition

Defines the tonal range of the shadows, midtones, and highlights in a clip. Drag the square sliders to adjust the threshold values. Drag the triangle sliders to adjust the amount of softness (feathering).

Shadow Threshold, Shadow Softness, Highlight Threshold, Highlight Softness

Determine the threshold and softness of the shadows, midtones, and highlights in a clip. Enter values or click the triangle next to the option name and drag the slider.
