I have a lot of videos from a Canon mini dv video camera. I imported them from my camera into iMovie, so now I have them all in an event. The videos play perfectly fine in iMovie.
I tried to copy all of these videos onto an external drive. To do this, I view the event in Finder, show package contents, and open original media; in that folder are the individual mov's that I want.
However, when I open these videos in, say, Quicktime, there is no sound. Maybe I am missing some codecs, but I want these videos and their sound to work like normal and not to rely on rare dependencies.
What can I do to fix these videos?
