Effect Controls

Mocha Mask and Track

Continuum effects include integrated masking and matte tools that allow you to restrict the effect to specific regions of the image.

• Mocha masks: used to create custom spline masks. Mocha also includes Matte Assist ML and Matte Refine ML, which use machine learning to generate and track masks.
• Pixel Chooser: used to generate geometric shapes, gradients, or mattes based on channel, luma, or color-based selections. Additionally, an AI depth map generator, and an AI-powered face detection model allow for precise control of masks and mattes.

For more information, see Mocha and Pixel Chooser.

Compare Mode

The Compare Mode is used to view the filtered result alongside the original source layer. Several split-screen and side-by-side display options are available.

For more information, see Compare Mode.

• View: Allows you to set the viewer to display various outputs for the Color Gradient.

  • Center: Lightens or darkens the center of the image.

  Spot Group

  A radial gradient (Spot) defines the region that is lightened or darkened. The Spot controls allow precise adjustment of its position and falloff.

  Note: In some host applications, you must highlight the effect title in the Effect Controls panel to enable the on-screen Position control.

  • Position: Adjusts the center of the radial gradient using the on-screen control.
  • Aspect: Sets the aspect ratio of the radial gradient.
  • Radius: Sets the unblurred radius of the spot.
  • Falloff Radius: Controls the width of the blurred transition area.
  • Falloff: Moves the falloff toward or away from the center point.
  • GPU Rendering:Specifies how the effect is rendered.
    • Default: Uses product-wide default of 16 bit half-float GPU rendering.
    • 16 Bit Float: Manually force 16 bit half-float GPU rendering.
    • 32 Bit Float: Manually force 32 bit full-float GPU rendering.
    • Disabled: Forces CPU rendering.
