<description>When colors change just a little, the filter decides that it is probably noise, and only slightly changes the color from the previous frame. As the change in color increases, the filter becomes more and more convinced that the change is due to motion rather than noise, and the new color gets more and more weight.</description>
<description>The higher you set it, the more youΓÇÖll cut down on noise ΓÇö but the more blurring you will see. In general, reasonable values range from 10 (to soften the occasional speckle without artifacts) to 25 (to reduce noise with minimal artifacts) to 45 (for better reduction, but visible blurring) up to 80 (to average out really heavy noise at the cost of bad blurring).</description>
