User Guide
Adjust the following controls for either the Noise HLS effect or the Noise HLS Auto effect:
Specifies the type of noise the effect adds. Uniform produces evenly distributed pixel noise. Squared produces
Noise
sparse, high-contrast noise that is distributed randomly. Grain produces grain-like noise that is useful for simulating
film.
Specifies the amount of colored noise that the effect generates, in proportion to the layer's hue values.
Hue
Specifies the amount of grayscale noise that the effect generates, in proportion to the layer's luminance
Lightness
values.
Specifies the amount of colored and grayscale noise that the effect generates, in proportion to the layer's
Saturation
saturation values.
This control is active only when you choose Grain from the Noise pop-up menu.
Grain Size
Specifies the random seed value for the noise. When you set keyframes for Noise
Noise Phase (Noise HLS only)
Phase, the effect cycles through the phases to create animated noise. Greater value differences between keyframes
increase the speed of the noise animation.
Specifies the speed of the noise animation. To increase the rate at
Noise Animation Speed (Noise HLS Auto only)
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.

Paint effects

Paint effect

The Paint effect lets you modify the color and transparency of a layer while leaving the source file unaltered. To use
this effect, apply the effect or simply select any of the paint tools in the Tools panel. You can use the Brush tool to
create spontaneous-looking writing or painting effects by animating paint strokes. You can use the Clone Stamp tool
to retouch footage and perform necessary tasks such as wire removal. Since paint strokes are applied as effects, you
can interleave them with other effects.
