Been trying to figure this out for a while. I have 2 FS100s, do sone long form multicamera shooting, when we format media cards ten file names start again at 000000.mts this is a major isue for us in our media management. On the EX1 this didn't happen, on the 7D this doesn't happen, the file names are continuous and on EX1 you can add clip prefix to files and they are continuous numbered unless you reset it. I can not find this on Fs100? If I missed it please tell me where, if not any recommendations would be greatly appreciated. We edit on Premiere Pro CS5.5 on Mac.
