That was an unfortunate experience and from the sounds of it, the lady in charge probably didn't handle it very well in being irate. However, many events will not permit video recording or even let dideo cameras in the venue. The higher the profile of the company/celebrity/ promotions company the more vigilant they are about it. Video includes audio and all it takes is an off color joke, off hand remark and a prominent person within that company is in big trouble. Digital recording is so easily edited and just as easily broadcasted on youtube, facebook etc. Video recording is also an uninterupted and all-encompassing and intrusive as opposed to just voice recording that normally is requested from the interviewee. I am not surprised that your video was stopped. This is not a reflection on Noront in my opinion.
