Eliminating
noise in video Noise in video, manifested
as "snow", refers to random dots and patterns that appear like static
on the screen. Noise is typically present in old movies
and videos recorded under poor lighting conditions. Digitized and over-enhanced
videos may also carry a lot of noise. In WinDVD, you can
easily eliminate or significantly reduce noise by using the De-snow filter. You
can apply De-snow filter to MPEG 2, VC1,
and H.264 videos. To
eliminate noise in video: 1. Open WinDVD 9 and start playing your
video. 2. Click Video and select Enhancement
to open the Enhance Video Panel. In the Enhancement
tab, you can select the filters to apply. 
Note:
If the video enhancement filters are not enabled, click 
Setup to open the Setup dialog box. In the Audio/Video Setup tab, make sure that
Use Hardware Decode Acceleration is not selected. This allows WinDVD to bypass
the hardware-based noise filtering technology provided by your video card. 3.
To remove noise from your video, select De-snow. Below
are screenshots of a video before and after the De-snow filter is applied.
