Well, if you front load your weddings, you don't really have an issue. If the video peeps are using their images from the wedding to advertise their biz. Not an issue. If they are selling stills (aka photographs) you have an issue.
This
silly thing that I posted about almost 2 months ago has gone down without 1 sale. I kid you not. I have not been able to confirm sales from the DJ or video peeps, but they must have. This is the only wedding we have ever shot that has had no post sales.
So, yes its a problem. ANY pro photog or video
KNOWS that there is an exclusivity clause. You have to work together and honestly its expected if you are both pros. If you had this clause, then it makes sense (if they are selling photographs) that it was violated. And odds are their clause does not cover exclusive photography - not too many photogs have videography clauses and vise versa. Video peeps would so come after us if we were capturing "streaming photographs" and selling them as photography.
If you are a PPA member, you should call and ask. If you front loaded your prices, and presold to the families, the video peeps can't really steal enough sales to justify the expense. On the other hand, if you didn't you'll have a lot of work with no sales.
