Many couples forget that wedding videos actually recreate those fleeting moments for you and your partner. Whenever you playback the video, happy memories of that special day flood back and in an instant, that warm fuzzy feeling is recaptured in full HD glory --- provided your videographer is worth his/her salt. After all, watching a video beats staring at still pictures that rarely communicate more than "cheese" and plastic smiles.
Don't forget, even your grandchildren can share the happy moments of wedding day --- that's assuming they weren't present at the event :). Sharing these experiences is very important as a form of imparting one's past, particularly events as important as these --- to the next generation.
Rarely spoken of, a wedding video can also offer solace to a grieving partner. Many avoid this topic as it may not be the most auspicious thing to suggest to a couple about to tie the knot. But just like an insurance policy, some things shouldn't be left unspoken, for years down the road, that wedding video can become a precious keepsake to help cope with difficult times.
