Lyric Self Composite
The Lyric Self Composite filter is a stylizing effect that can be used to produce a wide variety of special image effects. It is inspired by the many digital photographic effects that are achieved by layering a slightly-modified version of an image over itself and selecting one of the various compositing modes. The lyric filter lets you construct the blending layer via bluring, offseting, inversion and/or level adjusts and includes several unusual composite modes that can achieve interesting psychedelic effects. It also incorporates a composite iteration control, so that the blend layer can be composited multiple times to intensify an effect.
The default settings for this filter are neutral and make no change to the source video, it is a very general-purpose effects tool that invites experimentation.
The Lyric Self Composite 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.
Self Composite works by taking a copy of the source video image to make a compositing layer that is modified by the controls in the Composite Layer Effects section and then composited with the original source video using the mode selected in the Composite Mode dropdown menu.
The available modes are the same as those for compositing video tracks in Final Cut plus some additional modes, including Add & Subtract which are the same as Linear Dodge and Linear Burn in Photoshop, and three logical blend modes, And, Or and XOR which produce interesting psychedelic effects.
The Repetitions control specifies how many times to repeat the composite, which generally has the effect of intensifying the effect. The Fine Tune slider controls the transparency of the final composite, which essentially fine-tunes the composite effect.
The Composite Layer Effects section contains controls that modify the image copy prior to compositing. Perhaps the most commonly-used layer modification is blurring, controlled by the Blur slider. The Offset slider moves the compositing layer up and to the left by the number of pixels specified. This is often used to generate edge effects. Darken/Lighten adjusts the brightness of the compositing layer, and Invert and Desaturate perform the expected modifications.
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.
