Mask Generator

This effect lets you create a mask from any video or image. The video or image is converted to gray scale and made partially transparent. Brightness (luminance), one of the color channels red/green/blue or an alpha channel (for image files in PNG or TGA format) can be set under Type as an information source for transparency.

• Click on Apply effect to activate the Open FX plug-in.

Invert: Reverses transparent and opaque areas in the mask.

Low in/high in: Lets you determine a range between the minimum and maximum brightness values for the source (independent of type) for which the image/video will be opaque. If both values are the same, the mask created will have hard borders (threshold value), whereas if the second value is higher, a graduated fade will appear at the mask borders.

Low out/high out: Lets you set the minimum/maximum transparency value. If lows are increased in value, the entire image will become brighter (less transparent)

NOTE 1.0 corresponds to maximum white, therefore maximum opacity.
