MOV files profuced by Panasonic are a long GOP format that is highly compressed, so it is not a good playing and editing format. Some MOV video player and editing software can not handle this MOV files. I would suggest that you convert the MOV footage to the other common format, like MPEG, AVI as that format is easy to edit and playback. That is what I do with my MOV footage and the results are excellent. There are rare programs which allows to import and make deal with this high compressed MOV files. Now share a program called Aunsoft Video Converter which can convert and edit MOV footages perfectly. http://www.aunsoft.com/convert_canon_mov_to_avi_for_windows_movie_maker/
