Subject says it.
A band that we are promoting wants us to post concert videos on our website to advertise an event. The videos include images of the audience, including kids (it's a family music event, all ages). I see videos like these all over the place on band websites and it seems like pretty standard practice.
That said, we normally get photo releases even if we have implicit releases (e.g. all employees sign an agreement of understanding saying that photos of them while at work might show up in advertising materials, but we usually get a release anyway).
So we tend to err on the side of maybe going overboard and certainly going far beyond "normal" practice. But curious what people have to say about posting event videos if you can see who's in the audience.
