The BCC Levels Gamma filter provides options for adjusting contrast and eliminating noise in your image.
Video shot at night or in poorly lit settings often contains noise in the dark areas. Increasing Input Black removes this noise by treating all areas darker than the Input Black setting as black. Washed out or overexposed images do not contain the full range of levels. Increasing Input Black and/or decreasing Input White can boost the contrast of the image.
The built in PixelChooser, with integrated mocha planar tracking allows for greater control over which areas of the image the filter should affect.
