Can't import movie to iMovie
I can't import some movies to iMovie and can't work out why. I've changed the file formats from Mov to MP4 and so on; they play fine in Quicktime. iMovie 11 can see the files (not greyed out, in white) but I can't import.
I've tried to expert from Quicktime but that doesn't work. I've used AVCHD to change formats but none of that works. I've tried to import the videos on iPad as well but it's not working that way.
Any one have any ideas?
Thank you in advance
