Noise HLS effect and Noise HLS Auto effect
The Noise HLS and Noise HLS Auto effects
add noise to the hue, lightness, and saturation components of an
image. The noise generated by the Noise HLS Auto effect is automatically
animated noise; you choose the speed of the animation. To animate
the Noise HLS effect, use keyframes or expressions. Controls for
these effects are the same except for the Noise Phase or Noise Animation
Speed control, which controls noise animation.
These effects work with 8-bpc color.
Original (left), and with effect applied (right)
- Noise
- The type of noise. Uniform produces uniform
noise. Squared creates high-contrast noise. Grain produces grainlike
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.
