MP4 vs M4A
I have a huge collection of AIFF files that I had exported via QT to mp4 files. As of recently, I have a group who's doing some EDU podcast related stuff who was hoping to post up my podcast list, but sent me an email letting me know that they couldn't use the mp4 files, as iTunes is interpreting them as video files, and I needed to use .m4a.
I was wondering, since renaming the mp4 to m4a works like a charm and still opens in QT player, if I can just do a mass renaming of all my mp4s, or if I need to run them through another export to change them to m4a's. I notice that the mp4 audio files have an extra SDSM and ODSM mpeg4 track, which is what's making me a little bit uneasy of just renaming and wanted to check.
I'd like to avoid reexporting, since my macpro is estimating it at over 6 hours of reencoding.
Any help is GREATLY appreciated.
