Noise Phase
Specifies the placement of noise. This control is active only if you choose Uniform Animation or
Squared Animation from the Noise pop-up menu.
Noise Options (Animation)
Specifies how you animate noise.
•
Cycle Noise
Produces a cycle of noise that plays through once in the specified amount of time.
•
Cycle (In Revolutions)
Specifies the numbers of revolutions of the Noise Phase that the noise cycles through before
it repeats. (Available only when Cycle Noise is selected.)
Alter the timing of the Noise Phase keyframes to adjust the speed of the Noise Phase cycles.

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.
Noise HLS effect: Original image track (left); Noise HLS (center); Noise HLS applied twice with low Saturation values (right).
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 clip’s hue values.
Lightness
Specifies the amount of grayscale noise that the effect generates, in proportion to the clip’s luminance
values.
Saturation
Specifies the amount of colored and grayscale noise that the effect generates, in proportion to the clip’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.
