Hey,
I have undertaken such projects several times, creating pre and post wedding videos. I suggest creating a simple storyline as well to keep the audience interested.. something like -
This is a love story about a boy named Mark and a beauty named Laura, whose lives are going to change forever.
OR
The boy is Mark and Laura is the girl, he is the man and she seems to the pearl.

blossomed in library of the university of surrey, he asked her out while having indian curry.

Their loved ones are plenty and they should be too, friends love them as much as their family do.

Finally on 8th August 2013, Mark found the courage and the ring to keep Laura forever.

this is just an example, please dont go with the actual words and excuse my bad poetry, I can do much better if I actually put my mind to it. And even better if you give me details about your love story.
Anyways, this is just an option, we can go ahead with what you suggested as well, that infact would be easier for me :)
