iMovie event not viewable after import
Good day,
I put a GoPro HD Hero video (mp4 files) on an external drive (Windows XP formatted) and I try to import in into iMovie. When it's completed, I can't view the event movie : the image is black and, considering the sound, I always hear the same part of the movie which is not the first plan (I think it should because I renamed the files to be in chronological order).
I already did the same operation with another HD Hero movie, located at the same place, and I didn't encounter any issue.
Even after having imported the movie again and again, I got the same result.
I don't know what to do, so, if anybody could help, it would be great.
I work on a iMac, with last release of each software. The movie size is pretty long, as it reaches 10 hours.
Tank for your help.
P.S. : I will be out of home until sunday evening.
