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 the following program which can convert and edit Canon 7D MOV footages perfectly.
