MOV files profuced by Canon EOS 7D Mark II 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 heard that Pinnacle Studio 14 can natively support 7D MOV files but I have not tested it. You can have a try.

And another solution I recommend is that you convert the 7D footage to the other common format, like MPEG, AVI as that format is easy to edit and play back. That is what I do with my Canon 5D video 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 Canon 7D MOV footages perfectly.
