Hi guys, I just got a Macbook a couple of months ago and I need some help please with using iMovie ) I want to create a little movie using clips from my holidays. I downloaded them from dropbox... where they were uploaded for me by a friend. They were .mpg files at the time. When I found I couldn't open these in iMovie I did some google research and downloaded Any Video Converter Ultimate and converted them into .mp4 files. When I try import these newly converted files from Any Video Converter Ultimate into iMovie, the files appear grey and I cannot select them to import. When I try drag them in, I am told they are still incompatible. I have also tried moving them into iPhoto but that also tells me it's an unrecognised format... I just don't understand!! Can anyone help me or give advice please??
