Ok, here a link to my pack of filters :
http://dl.free.fr/qXfb5FsxH
Get the rar file, unpack it in "plugins" of VDub.
Ok, there is a lot of filters. Some have name spoke for them.
The filters you may need are :
Median V2.0.0
Chroma Shifter V1.0.0
Ignore alls VHS filters, they are now totaly useles with filters
like NV !!!
Median filter : You can chose the filter mode, i suggest you chose
"Vertical". Filter size is the number of pixels used around the
center wich the filter will use to do the median. Try 1 or 2, but normaly
not more to reduce side effect.
Threshold is the min differance value betwen the pixel value and
median value for the filter to be applied. Default value are for YCbCr
mode, in RGB, default value are 20,20,20. Maybe try to filter only Y
(if your video is in YCbCr mode), i dont know if VHS dropouts are only
on Y channel or all. But, you can disable filter on some channels if
you want.
Setting/Test mode : allow you to see where the filter will be applied,
the pixels will be marked on high colors. Use it to adjust the size and
the threshold level to have "only" the dropout filtered.
Interlace mode : Check it if you work on interlaced video.
Note : Median filter is slow, and speed decrease as filter size increase.
Chroma shift : Allow you to shift chroma as you want, often useful
on VHS.
If it's not the case, i strongly suggest you to get the last version
of VDub (1.8.6), and of course, to work with YCbCr video.
Tel me when you've got the file, i remove it after.
