Maybe this is dumb question, but what did your contract stipulate? Maybe a point to consider in you next job.
It's not a contractual issue - we agreed to make them a 2-minute-ish video and also send a few photos and the raw video. We gave them our final video, and offered to make any changes they wanted. They decided it would be easier for them to just edit with their own guy on site, for logistical reasons (we're 5 hours away).
We don't really have a problem with them editing the video - we assumed that their video professor would be able to put together something decent. Obviously we were mistaken.
The question is whether we should contact them and ask about changing at least the music. We don't feel that we have a right to MAKE them change the vid - no interest in power plays anyhow - just wondering if we should talk to them about it.
I'm kind of resigned to let it be right now. Apparently for some reason they're happy with it - we still have our cut we can use for promotional stuff, and they're ok, so let it roll. But my god I can't stand watching that thing.
