I have to make a video for our school sport presentation evening. my school has alot of sports team and they want like a 5-10minute video with highlights and interviews and whatever else. was wanting to use a shotgun mic on a boom pole, however someone was telling me that you need a ballam box or some thing that goes on the bottom of the camera. Our camera's have a mic in and a line in which are both 3.5 jacks and the shotgun mic is a xlr. Can i just get a xlr-jack lead and plug it in the mic in, or do i have to use one of these ballam box thingies??
