Noise HLS and Noise HLS Auto effects
The Noise HLS effect generates static noise in clips that use still or moving source footage. The Noise HLS Auto
effect automatically creates animated noise. Both effects offer various types of noise that can be added to the hue,
saturation, or lightness of a clip. Controls for these effects are the same except for the final control that determines
noise animation.
