Noise image effect

Noise is an image postprocessing effect that can simulate both TV and VCR noise.

Like all image effects, Noise is only available in Unity Pro. Make sure to have the Pro Standard Assets installed.

Noise effect with high intensity applied to the scene


Monochrome	If enabled, Noise is more similar to TV noise. If disabled, it more resembles VCR noise - it distorts color values in YUV space, so you also get hue changes, mostly towards magenta/green gues.
Grain Intensity Min/Max	The intensity of noise takes random values between Min and Max.
Grain Size	The size of a single grain texture pixel in screen pixels. Increasing this will make noise grains larger.
Scratch Intensity Min/Max	The intensity of additional scratch/dust takes random values between Min and Max.
Scratch FPS	Scratches jump to different positions on the screen at this frames per second.
Scratch Jitter	While being in the same position, scratches can still jitter a bit.

Hardware support

Noise effect works only on graphics cards with support for pixel shaders (model 2.0) or devices with OpenGL ES2.0 support. Eg. GeForce FX 5200 or Radeon 9500 and up. All image effects automatically disable themselves when they can not run on an end-users graphics card.
