Alparysoft Denoise Filter is for removing noise from the video image.

The filter for removing noise from the video image. In the process of recording video, as well as at its transmitting and transfer to various carriers, different kinds of noise worsening the quality of video image can appear on the tape. Besides, high- frequency noise reduces the compression coefficient of the video. Reducing the video image noise is what this filter is intended for.
<p>
The filter is constructed according to the Microsoft. DirectShow. technology, and can be inserted into various programs which support this technology. The filter provides the intra-frame and inter-frame noise suppression. Automatic noise level evaluation (which enables the filter to automatically determine the applicable techniques) can be switched on at the "Properties" page of this filter; or you can choose the noise suppression level yourself.

The filter can be applied to two kinds of videos:
high quality (low noise level) - the quality of the image will remain largely unchanged, while the gain in compression rate will make up to 10%.
much noise - the quality of the video image will be improved, and the gain in the rate of compressing to MPEG format can make up to 80%. For practically all movies with much noise, the 1.5 times increase in compression rate has been observed.
