yuvdenoise  is a spatio-temporal noise-filter for YUV4MPEG2 streams. This is useful to reduce the bitrate
       needed to encode your captured movies for VCD and SVCD creation.

       yuvdenoise - Motion-Compensating-YUV4MPEG2-frame-denoiser

yuvdenoise accepts the following options:

       -gy,u,v[0..255]Gaussianfilterthresholds
           This sets the thresholds for the gaussian filter.  A value of 0 disables  filtering  for  a  specific
           component  and  0,0,0  completely  disables/bypasses  the  filter.  This filter is applied before the
           temporal (-t) filter.
           (default=0,0,0)

       -my,u,v[0..255]Pre3DMedianfilterthresholds
           This sets the thresholds for the pre-processing 3D median filter.   A  value  of  0  disables  median
           filtering for a specific component and 0,0,0 completely disables/bypasses the filter.  This filter is
           applied before the temporal (-t) filter.
           (default=0,0,0)

       -ry,u,v[0..255]Renoisingfilterthresholds
           This  sets  the thresholds for adding random "noise" back into the video stream.  Default is disabled
           (not adding random noise).  This filter, if enabled, is run as the Blast filter (after the median and
           temporal filters).  Reasonable value is 4,8,8 but if you are working with monochrome (black and white
           movie) then 4,0,0 will speed things up by not processing the chroma planes.
           (default=0,0,0)

       -ty,u,v[0..255]Temporalnoise-filterthresholds
           This sets the thresholds for the temporal noise-filter.  Values above 12 may introduce ghosting.  The
           default value for Y' (y) is often a little high and reducing it to 4 or 5 may be necessary.   If  the
           chroma  smears  or  ghosts  try  using  values  of  5 or 6 instead of the default (12).  A value of 0
           disables temporal filtering  for  the  specified  component  (0,0,0  disables/bypasses  all  temporal
           filtering).  Thus for black and white movies 4,0,0 will be faster by not denoising the chroma planes.
           (default=4,8,8)

       -My,u,v[0..255]Post3DMedianfilterthresholds
           This  sets  the  thresholds  for  the post-processing 3D median filter.  A value of 0 disables median
           filtering for a specific component and 0,0,0 completely disables/bypasses the filter.  This filter is
           applied after the temporal (-t) filter.  Reasonable value is  4,8,8  but  if  you  are  working  with
           monochrome  (black  and  white  movie)  then  4,0,0 will speed things up by not processing the chroma
           planes.
           (default=0,0,0)

       As it is self-adapting to the noise-situation found in the stream you normally just can  go  without  any
