Innobits Video Purifier removes contaminations in videos. Contaminations are defined as dithering artifacts, unwanted video noise and unpleasant signaturs from filtering processing. Innobits Video Purifier removes only noise that shouldn't be in the video in the first place, which means that animated noise is not touched. Also, InnobitsVideo Purifier does not "smear out" the noise or put any "new" pixels into the video - it simply uses already existing pixels.
To see is to believe! Please feel free to download these samples of Purified videos.
