Hey gang, I'm shooting a corporate project and part of it involves shooting a presentation screen all day. The camera is on a tripod and every hour I check the frame and change tapes. I'm shooting these with a Sony 1000N (Mini DV Cam using Sony DVC tapes) and I've never had a mini dv camera shooting for this many hours and days straight. I spot check every once and awhile but I wont be capturing this footage until next week. Should I be running a head cleaner? If so how often? What kind of stress is 6 or so hour long tapes a day putting on the camera?
