Missing audio from QuickTime after importing from iMovie.
I'm trying to export an iMovie project to Quicktime and there's no audio when I play it back in Quicktime. The volume's not muted in iMovie and I've tried all of your steps above.
First, try SHARE/EXPORT MOVIE in the sizes you want. See if the audio works.
If it does, then go back to SHARE/EXPORT TO QUICKTIME and tell us which audio and video codecs you are using.
