Noise Options (Animation)
How noise is animated.
•
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 if 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.
Original (left), and with effect applied (right)
Noise
The type of noise. Unique Random creates equal amounts of black and white noise. Squared Random creates
high-contrast noise. Uniform Animation creates animated noise, and Squared Animation creates animated high-
contrast noise. Grain produces grain-like noise similar to film grain.
Hue
The amount of noise added to hue values.
Lightness
The amount of noise added to lightness values.
Saturation
The amount of noise added to saturation values.
Grain Size
This control is active only for the Grain type of noise.
Noise Phase (Noise HLS only)
An input value to the random number generator 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)
The speed of the noise animation. To accelerate or decelerate the noise
animation, animate this property.
