Noise: Keyframes Video Filter

Adds synthetic visual noise to the image to introduce randomness, texture, or signal degradation.
Unlike film grain simulations, this filter produces a digital-style noise that can be animated over time.

Noise: Keyframe is a spatial effect evaluated per frame.

Parameters

Amount (0.0 - 100.0%)

Controls the intensity of the noise applied to the image.

  • Low values (≈0.0 - 20.0%)
    Subtle noise. Fine speckling is visible primarily in flat or midtone areas.

  • Mid values (≈20.0 - 60.0%)
    Clearly visible noise. Texture becomes apparent across most of the image.

  • High values (≈60.0 - 100.0%)
    Strong noise. A structured pattern may become visible, with noise appearing to align along rows and columns.

Notes:

  • The noise is not monochrome; particles contain subtle color variation.
  • At high values, the noise can appear grid-like or patterned, rather than fully random.
  • Noise is applied uniformly across the frame; it does not respond to luminance or edges.

Keyframes

The Amount parameter can be keyframed.

This enables:

  • Gradual buildup or reduction of noise
  • Pulsing or rhythmic noise effects
  • Time-based transitions between clean and degraded images

Visual characteristics

  • Fine to coarse digital noise
  • Slightly colored noise particles
  • Uniform distribution across the frame
  • At high values, visible structure rather than purely random grain
  • Can reduce perceived image clarity and contrast

Recommended use cases

  • Glitch or digital degradation effects
  • Simulating signal interference or instability
  • Adding texture to flat or synthetic imagery
  • Transitional effects using animated noise
  • Abstract or experimental visuals

Tips and usage notes

  • Use low Amount values for subtle texture; higher values quickly become dominant.
  • Evaluate the effect at full resolution, as noise structure is resolution-dependent.
  • Keyframing small fluctuations in Amount often looks more natural than large jumps.
  • This filter is not a replacement for film grain or photographic noise simulations.

Limitations

  • Noise pattern may appear structured at high values
  • No control over noise color, scale, or distribution
  • No luminance-based or adaptive behavior
  • Can introduce visible banding or patterning when overused
