Yon,
I have not looked at the clip (same results as highlighted above), so this may be invalid. Is there room for some artistry in the wedding clip? If so, try black & white (or seriously desaturated color), add a slight blur, and some slow motion with a Linear Timewarp. Perhaps a touch of the Dream Glow filter that blows out the whites, adding to the surreal look. Don''t overdo it though.
Depending on how bad the snow is, it could well become a non factor.
