Video information that is input in digital video recorders or distributed over the Internet comes in various different qualities. One possibility to improve the video quality and also to improve the efficiency of the video encoder is to use different types of spatial or temporal video filters. This paper presents a comparison of the noise reduction efficiency for three different video filters. Additionally, the improvement of MPEG-2 encoding efficiency is compared. The results provide an efficiency function that can be used to select an appropriate filter type for a special situation.
