Noise
The Noise effect adds noise, or pixels with randomly distributed color levels. This effect is used to add some texture to an image by way of tiny pixel dustings. The Noise effect can be used to conceal "touch-ups" of a flat color on an image, or remove other problem areas.
In the Properties Area of the Video Effect window you can change the effect propertieschange the effect properties.
The properties of the Noise effect available for setting are its level and the monochrome option. If you check the Monochrome box, it will apply the filter to the tonal elements in the image only without changing the colors.
In the figures below you can see the video picture before and after applying the Noise effect:
