For years when making internal communications videos to send to staff at our hotels round the world, we dilligently produced tapes in either PAL, PAL-M, PAL-N, SECAM, SECAM-V and NTSC (I'm told this stands for Not The Same Colour
). Only recently, when we switched to a different Video production company, did they tell us that it's not necessary to produce VHS tapes in any of the variants. Apparently the variations in the standards only become important when you're working with broadcast quality material. We decided to go with it (and save a fortune) and produce our tapes in the three basic standards. We had no complaints.
