Lyric Luma-masked Grain

Luma-masked Grain

The Lyric Luma-masked Grain filter is a stylizing effect that applies simple noise-based grain to the source video image through a controllable level-threshold mask to more closely simulate the way grain appears in film, which is generally only visible in the midtones. In the examples above, the added grain is not present in the shadows or highlights. The filter also provides a set of selectable noise-compositing modes.

The Lyric Luma-masked Grain filter includes a set of effect controls that are common across all Lyric effect filters. For a detailed description of these controls, please see the Common Effect Controls documentation.

Additionally, all Lyric Effect filters can be applied through mattes or masks to constrain the filter effect to particular areas of the image. For background information on mattes and masks, please refer to the Lyric Matte Primer.

The Grain Level slider controls the intensity of the grain noise.

Mask Highlights controls the amount of highlight masking, higher values mask the noise out of a broader range of highs, setting it to 0 will apply the noise to all tone levels above middle gray.

Mask Shadows controls the amount of grain-masking in the shadows, higher values mask the noise out of a broader range of shadows, and a 0 value applies the noise to all tone levels below middle gray.

The Rolloff slider controls the smoothness of the mask transition, higher values soften the transition from grain to no-grain.

The 4 modes in the Composite Mode dropdown menu are a subset of the standard Final Cut compositing modes and control the way the grain noise is applied to the underlying video image. Blend and Overlay are the most common, Lighten and Darken are often used for special effects.

By default, the grain noise is animated, changing from frame-to-frame as in film. Checking the Static Grain checkbox will stop this animation, keeping the grain identical from frame-to-frame.

The Effect Controls section is a set of common controls that are documented on the Common Effect Controls page. They can be used to achieve masked and other specialized filter effects.
