I have some Quicktime movie files that I want to use in iMovie, but they’re in the MPEG 1 muxed format; when I import to iMovie, I lose the sound file.
How can I convert them for use in iMovie? I have MPEG Streamclip, but no Quicktime Pro (which is one way, apparently).
Any help is much appreciated. I’m a bit of a tech idiot, so please type very slowly.
