I need to find a shortcut in renaming several video files at once instead of having to rename each file by itself. I need the video files to be in order chronologically and having to rename 100 video clips takes too long when I have to do it everyday. I can't cut and paste cause the files need to be "(video name) 1 of 100" or some variation of that. There is a short cut in Windows to do this, with this known there has to be a mac way.
