Of course, with moving media the results can be less than stellar (pun intented). We found out that it does work, especially if you have a clip filmed under high-gain, low-light conditions. Our plug works by combining the last n (user configurable from 1 to 10) frames, and averaging them. Therefore, if you have any fast-moving objects in the clip, they will exhibit ghost trails. Depending on their speed, these trails will be more or less pronounced. Very fast objects (i.e those that appear in only one or two frames) will disappear entirely (which is, of course, the definition of noise reduction).
