The filter for VirtualDub to remove video noise on VHS
movie. 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.
The level cut of noise can be regulated for any of
color components. The filter is optimized for
processors with support MMX-technology.
