Just to add to Z cheema's post. This has also been my experience. There are those that are great at graphics and intro's with AE etc, and then fall far short with the actual footage!

There are those not so good with graphics and intros but more than make up for it with a fantastic wedding video with beautiful composition, technique, and overall style.

I would rather fall in the latter of the two. I would like to be able to do it all, but if I had a choice my first priority would be the footage of the day, followed by the edit.

Still excellent stuff.
Cheers
