Luminance To Alpha

A filter that lets you assign an alpha channel to your media based on a luminance range. Pixels outside this range become transparent.

Compatibility

Luminance To Alpha is compatible with Final Cut Pro, Motion, Premiere Pro and After Effects.

Parameters

Range

Luminance range that is preserved, remaining opaque in the output.

Softness

This parameter lets you smooth the transition between pixels in the range and those outside the range. In doing so, there is less contrast between opaque and transparent pixels.

Background Color

Set to
transparent black by default.
Color used to fill any areas that become newly-transparent as a result of applying this filter.
