I work in video production and I highly believe that it is a huge part. I don't do weddings but I believe a camera can capture so many moments that are forgotten or not noticed. Although you may not watch it every other weekend, it's such a great token to have for years to come - and something your children would love to see someday.
If you're only doing a ceremony, I suggest getting a videographer who will shoot with 2 cameras (at least!). A ceremony is an easy edit but only easy if you have more than one camera!
Just a piece of advice , make sure you communicate with your videographers!!! Nowadays, so many people believe that they can purchase a decent camera and some easy editing software and bam, they're pro's. Please be careful!!! Cameras and editing equipment are so inexpensive nowadays and sometimes you can get someone for a really inexpensive price and your edit turns out horrible.
Please do your research! Style is super important. Do not assume they know what they're doing. Make sure you ask key questions:
1. How long will you be shooting (how many hours)
2. How many cameras will there be (the more camera's the better. Two is ideal, three is amazing! - because they'll have more angles to cut to and more options)
3. What are you shooting on (HD/non HD - which even if they're shooting in HD- doesn't necessarily mean your video will be in HD if they don't have blu ray burning capabilities. Also, HD can mean 720 p. - True HD is 1080p or higher.
4. Will you get raw footage (if so, is this on dvd or tape or whatever media they're shooting on - if you get raw footage on dvd that you plan to edit yourself, remember that your footage is compressed by then so if you edit it, you will lose quality as it will have even more compression).
5. How many years have you been doing this?
6. How many weddings have you shot (shooting weddings is very different than shooting other videos).
7. What's your turnaround time for an edit?
8. How long should I expect my wedding video to be (please ask this, poor Skylarr got screwed on her video and I hope this doesn't happen to anyone else)
There are plenty other questions but feel free to PM me if you have specific questions when it comes to video. Good luck guys!
Anyway, I can go on and on but I think it's a wise investment. You are getting what you pay for though, so be careful on skimping on extremely inexpensive vendors.
