I am trying for the first time to create a slideshow using Lightroom 2005.3 on a Mac running OS running 10.10.5.
Firstly, I can add the MP4 music files ... i select the files, but the music is not added ... no error message, the music is just not added.
Even more annoying is that when i attempt to play the slideshow or preview it, all i see is a black screen and nothing happens. Suggestions would be appreciated.
I'm not sure but it might have something to do with DRM. If the song/music you are trying to add didn't come from a CD you personally own and burnt down to MP3 format Apple/Mac/OS X might be stopping it from being added. Like if the music you are trying to add you downloaded from the iTunes store that is very restrictive on what you can do with it other than listen to it on your Mac, iPhone or iPod.
Actually, the music files in question came from my own CD but were uploaded into itunes ....
