The filters for clearing the video of noise for VirtualDub, Adobe
Premier. Its main task is suppression of noise as small bright lines,
red or blue color, less often green. Because of discontinuity of a
magnetic layer of VHS-tape such lines always are present at the image.

The filter analyses each frame irrespective of others, due to what it
brings in additional distortions in comparison with dynamic filters
(practically there is a loss of clearness in comparison with the
operation blur). In aggregate with high accuracy of definition of noise
the given filter, probably, is the leader among similar filters for
VirtualDub. Is especially convenient at coding in MPEG4 or DivX, since
even after deleting small noise the size of the encoded file decreases.
As the filter relieves from interlacing and the additional filter is not
required.

The level cut of noise can be regulated for any of color components. The
filter is optimized for processors with support MMX, which allows making
reduction of noise in real-time mode.
