I have a similar problem to this person on the Apple discussion board
I spent almost 60 hours building, narrating and editing a Keynote presentation only to find that when I export the file to Quicktime, the audio isn't included. Its a silent film
The advice given in that thread has not worked for me.
The presentation already has all the sounds embedded, hence there's no need for a mic so I use Soundflower as the system output to create an audio sinkhole, like sending to
/dev/null. When I export the movie (
File > Export > Movie, and I've tried both
Slideshow Recording and
Self Playing) I get a silent film and any video or sound files that were in the presentation are just stills and do not play.
However, if I choose
Play > Play Recorded Slideshow then everything is fine, the presentation movie plays with all the video and sounds all at the times I set them off. If I knew the location of that recording then I can ignore the export's strange ideas on how to process the recording and take that.
I've unzipped the .key file and found a file called
MovieRecording-XXX.mov (where XXX is some kind of GUID) but it's really an audio track, and of course, it's mute. I can't find the whole video that is inside Keynote.
~/Library and I'm trying the temp directories but have found nothing so far. I have also looked through the data/metadata in the unzipped dirs and can't find a reference to it.
I'm actually about to try and make a screen recording of the one inside Keynote but that's obviously not ideal.
Any help or pointers will be much appreciated.
