Adding Grain Using a Custom or Monochrome Grain Signature
 
 
 

Use the Custom option to define Red, Green, and Blue Gain curves that are used to generate the grain signature.

Using the Mono option, you can also apply custom monochrome noise, an option that is useful if you are adding grain to monochrome clips. Monochrome noise does not have to be black and white noise. You can adjust the Red, Green, and Blue curves to tint the grain in cases where you are adding grain to, for example, sepia monochrome clips.

To add grain by defining a custom colour or monochrome grain signature:

  1. From the Grain Signature box, click Custom or Mono.

    Instead of RGB sliders, the Custom option provides Red, Green, and Blue Gain curves for each channel that you can edit to produce the grain signature that you need:

  2. To add grain to the clip, adjust the Red, Green, and Blue Gain curves.

    The Red, Green, and Blue Gain curves represent the degree of grain added along the vertical axis, and the corresponding luma value of the selected channel on the horizontal axis. For example, to add grain primarily at the higher luma range of the red channel, drag the right-most control point of the red curve upward.

    (a) Gain curves  

    The Red, Green, and Blue Gain graph provides a thorough set of controls that you can use to modify the Red, Green, and Blue Gain curves as needed:

  3. To adjust the radius of the grain along the X-axis, drag the RGB Radius X sliders:
  4. To adjust the radius of the grain along the Y-axis, drag the RGB Radius Y sliders:
  5. When you are satisfied with the result, click Process to add grain to the clip or continue building your processing pipeline in Batch.
