Noise > Noise HLS effect, Noise HLS Auto effect

The Noise HLS effect generates static noise in layers 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 layer. Controls for these effects are the same except for the final control that determines noise animation.

Adjust the following controls for either the Noise HLS effect or the Noise HLS Auto effect:

Noise

Specifies the type of noise the effect adds. Uniform produces evenly distributed pixel noise. Squared produces sparse, high-contrast noise that is distributed randomly. Grain produces grain-like noise that is useful for simulating film.

Hue

Specifies the amount of colored noise that the effect generates, in proportion to the layer's hue values.

Lightness

Specifies the amount of grayscale noise that the effect generates, in proportion to the layer's luminance values.

Saturation

Specifies the amount of colored and grayscale noise that the effect generates, in proportion to the layer's saturation values.

Grain Size

This control is active only when you choose Grain from the Noise pop-up menu.

Noise Phase (Noise HLS only)

Specifies the random seed value for the noise.When you set keyframes for Noise Phase, the effect cycles through the phases to create animated noise. Greater value differences between keyframes increase the speed of the noise animation.

Noise Animation Speed (Noise HLS Auto only)

Specifies the speed of the noise animation. To increase the rate at which the noise effect changes, set the value higher. For slower changing noise, set a lower value. To accelerate or decelerate the speed of the noise, set keyframes for this control.
