I understand what you're saying re: it being just the best bits, but there really is no other way of doing it. We could have a showreel that's made from one wedding, but it'd still be the best bits and wouldn't give a broad view of the different weddings we do which in turn would lead to the same problem. We've never had a client say anything along the lines of "why didn't my film look as good as this?" though, because on the whole they do and of course that's why we give out sample DVDs of full films as well.
Would you offer clients the choice of recorded sound or not?
Of course, though that's never been asked or queried before!
Do you find that you clash with Photographers at all?
Not at all. We're unobtrusive anyway for the couple's benefit and this is obviously a benefit for the photographer too. We have a good relationship with most of the photographers we meet (unless they're rubbish), and the majority of our referrals come from photographers. We've even saved their skins a couple of times after they weren't told (or they forgot) to get shots of certain people such as Uncle Dave but we were able to pick off a still from the film. Another photographer included our stills in the wedding album by request of the bride.
In my experience, the videographers get a bit tetchy when they are videoing something like the speeches, and they tell me the shutter sound and flash (if used of course) are ruining their footage.
I don't suppose there's a lot to be done about it though, I'm there to do a job, and so are they?
The only time we get tetchy with photographers is when they stand right in front of our cameras, especially when they're not even taking a shot. We use two radio mics so we can never hear shutter clicks and flash hardly makes a difference.
Right, music! Tricky one.
We would pay, except nobody has ever asked us to. That and the music isn't integral to the film (if we were asked to pay thousands, we'd just use another track) and the majority just goes into the pockets of people totally unrelated to the song.
You're supposed to pay for copyright through the WVRL for every single DVD we produce as well, which is ridiculous. You could have five Take That tracks or five tracks from some unknown but signed artist and you'd still pay the same amount. And they don't ask what tracks you've used, so how on earth can it possibly be paid out fairly?
If YouTube allows the track to be used (with ads) then that's fine by us for now

Again, thanks for all your comments.
