I have been working and since I could not find a denoise filter in
gimp I went to video editors. Cinepaint would not compile due to
errors during the make command so I tried avidemux which would open
dv2 files but not rawdv so I have to use kino to convert. In the end I
am using kino to figure out video sections (non linear) then use that
info in avidemux which has alot of filters.

I have found that a "mplayer hqdenoise" with tripling all the default
numbers helps then a "sharpen" with standard settings, helps make the
ceremony and gift opening good enough quality

I have not had time to play with a million variations so if anyone
nows better settings I would like the help. Now I have found I want to
play with the reception to find a way to lighten it up a bit. without
losing quality or a filter after the lightening up to fix it (I don't
worry about encoding timesince this is important footage)

those filters plus settings of 2 pass dvd(lavc) aimed to fit 2 hours
into 4 gigs (room for photo slideshow and menu) will give good results
