Noise image effect
Noise is an image postprocessing effect that can simulate both TV and VCR noise.
As with the other image effects, this effect is only available in Unity Pro and you must have the Pro Standard Assets installed before it becomes available.
Noise effect with high intensity applied to the scene
Monochrome | If enabled, Noise is similar to TV noise. If disabled, it more closely 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 framerate. |
Scratch Jitter | Scratches can jitter slightly while remaining close to their original positions. |
Hardware support
This effect requires a graphics card with pixel shaders (2.0) or OpenGL ES 2.0. PC: NVIDIA cards since 2003 (GeForce FX), AMD cards since 2004 (Radeon 9500), Intel cards since 2005 (GMA 900); Mobile: OpenGL ES 2.0; Consoles: Xbox 360, PS3.
All image effects automatically disable themselves when they can not run on end-users graphics card.
